COVID-19 is linked to novel seizures and subsequent adverse outcomes, including death, in patients without a previous history of epilepsy, new research shows. In a retrospective study of more than 900 patients admitted to the hospital with COVID-19, those without a known history of epilepsy had three times greater odds of experiencing novel seizures than those with a known history of epilepsy.

In addition, among patients with new-onset seizures, hospital stays were about 15 days longer – and mortality rates were significantly higher.

“We’re finding that there are many neurological consequences that can happen with COVID-19 infections, and it’s important for clinicians to keep that in mind as they monitor people long term,” said study investigator Neeraj Singh, MD, neurologist and epileptologist with Northwell Health System, Great Neck, New York.

Dr. Singh noted that although seizures “might not be the most common thing we see in people with COVID-19, they seem to be new seizures and not just a seizure we knew would happen in someone with epilepsy.”

“So there’s definitely a need now for more prospective research and following people over time to fully understand all the different things that might be newly a problem for them in the long term,” he added.

Dr. Singh and Hardik Bhaskar, an undergraduate student at Hunter College, New York, presented the study findings at the American Academy of Neurology’s 2021 annual meeting.
 

Largest sample to date

“This study explores the relationship between the incidences of COVID-19 infections and [novel] epileptic seizures in the largest sample to date in a single New York–based hospital system,” the investigators noted. Novel seizures included both new-onset and breakthrough seizures.

Dr. Singh told meeting attendees that the “early epicenter” of the COVID pandemic was in New York and occurred from Feb. 29, 2020 to June 1, 2020. Patients with COVID-19 “had multiple neurological sequelae, including seizures, strokes, and encephalopathy,” he said.

However, the effects of COVID-19 on individuals with epilepsy “remain unclear,” Dr. Singh said.

For their study, the researchers assessed 917 patients in 13 New York City metropolitan hospitals. All participants had received a confirmed positive test result on PCR for COVID and had received an antiepileptic medication upon admission. The patients were admitted between Feb. 14 and June 14, 2020.

For the study, the patients were first divided into two groups: those with a history of epilepsy (n = 451), and those without such a history (n = 466).

The first group was further divided on the basis of those who presented with breakthrough seizures and those who presented without them. The second group was further divided on the basis of those who presented with new-onset seizures and those who presented without them.
 

Significant adverse outcomes

Results showed that 27% of the patients without a history of epilepsy experienced a novel/new-onset seizure and that 11% of the patients with a history of epilepsy experienced a novel/breakthrough seizure (odds ratio, 3.15; P < .0001).

In addition, participants with new-onset seizures had a longer stay in the hospital (mean, 26.9 days) than the subgroup with a history of epilepsy and no breakthrough seizures (10.9 days) and the subgroup with a history of epilepsy who did experience breakthrough seizures (12.8 days; P < .0001 for both comparisons).

In the group of patients with a history of epilepsy, there were no significant differences in lengths of stay between those with and those without breakthrough seizures (P = .68).

Although mortality rates did not differ significantly between the full group with a history of epilepsy versus the full group without epilepsy (23% vs. 25%; OR, 0.9), the mortality rate was significantly higher among patients who experienced novel seizures than among those who did not experience such seizures (29% vs. 23%; OR, 1.4; P = .045).

Mr. Bhaskar noted that there are “many hypotheses for the mechanism by which COVID-19 might cause seizures.” Those mechanisms include proinflammatory cytokine storms, which may increase the rate of apoptosis, neuronal necrosis, and glutamate concentrations and may disrupt the blood-brain barrier. Another hypothesis is that SARS-CoV-2 infection may lead to hypoxia and abnormal coagulation, resulting in stroke and a subsequent increase in the risk for seizures.

Interestingly, “the presence of antiepileptic medications in patients with epilepsy may confer a protective effect against breakthrough seizures,” Dr. Singh said. “However, some subclinical seizures may be misdiagnosed as encephalopathy when patients present with COVID-19 infections.”

He added that further research is needed into the mechanisms linking these infections and new-onset seizures and to “identify subclinical seizures in encephalopathic patients.”

Asked during the question-and-answer session whether the investigators had assessed differences by demographics, such as age or sex, Dr. Singh said, “We have not subdivided them that way yet,” but he said he would like to do so in the future. He also plans to look further into which specific medications were used by the participants.

The investigators have reported no relevant financial relationships.

Black patients with multiple sclerosis (MS) or neuromyelitis optica spectrum disorder (NMOSD) may respond differently to common MS treatment compared to their White peers, new research suggests. In a study of almost 200 patients, Black participants with MS or NMOSD showed significantly more rapid B-cell repopulation 6-12 months after receiving anti-CD20 infusion therapy with rituximab or ocrelizumab (Rituxan, Ocrevus, Genentech) than did White participants.

“The results showed that this B-cell targeted therapy wore off more quickly in African Americans,” said study coinvestigator Gregg J. Silverman, MD, a professor at New York University.

He said that, although the study was more observational in design, “over time when people come back to the clinic, it gives you an idea of whether the agent is still working in their bodies.”

Overall, “our findings raise the question of whether the same therapy dose may be equally effective for all people,” coinvestigator Ilya Kister, MD, also from NYU, added in a press release.

Dr. Kister noted that this could have implications for the way Black patients with autoimmune diseases are treated in the future.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

More severe disease in Black patients

Anti-CD20 infusion therapy, or B-cell depletion therapy, is commonly used to treat autoimmune diseases, including MS and NMOSD. “While previous research has shown that this type of infusion therapy is effective for people with these diseases, we also know that Black people tend to have more severe courses of MS,” Dr. Kister said.

“We wanted to compare how quickly the B cells came back in Black people and White people after treatment,” he added.

Dr. Silverman noted that he has been “studying this agent in autoimmune disease for many years. And from all the different studies, I don’t think we had the right population to ask this question. Demographics were just reviewed as they were.”

The current study included 168 participants (mean age, 44 years; 71% women) who had a diagnosis of MS (n = 134) or NMOSD (n = 32) or who were considered to have MS or NMOSD (n = 2). In addition, 36% of the participants self-identified as Black or African American, 36% self-identified as White, and 28% self-identified as another race.

Flow cytometry results were available for all patients after undergoing anti-CD20 infusions at the NYU MS Care Center. Cluster analyses were conducted on the following B-cell subsets: CD19, CD20, IgD, and CD27. “B-cell repopulation was defined as any detectable number of CD19+ cells on flow cytometry,” the investigators reported.
 

Clinical implications?

Results showed that 29.8% of the full study group showed B-cell repopulation a mean of 6.8 months after infusion. In those with B-cell repopulation, 80.3% had IgD+/CD27– subsets, 11.6% had IgD–/CD27+, 6.2% had IgD–/CD27–, and 1.8% had IgD+/CD27+. These B-cell subset ratios did not differ significantly between the Black and White participants.

Interestingly, no patients showed B-cell repopulation before 4 months after infusion. From 4 to 6 months after infusion, there were no significant differences between the Black and White participants in terms of frequency of B-cell repopulation (20.8% vs. 17.9%, respectively; P = .79).

However, repopulation was significantly more frequent in the Black patients 6-12 months after infusion (76.2% vs. 33.3%; P = .02).

Overall, the findings “may have implications for clinical management of MS/NMOSD” in Black individuals, the investigators wrote.

“I was impressed by the differences we saw in responses of patients that were self-declaring as African Americans versus those who were Whites,” Dr. Silverman said. However, “as we say in science: it gives us an answer but it raises even more questions, which may well be important for helping us understand how the agent works and how the disease affects different people.”

Still, Dr. Silverman noted that the findings give clinicians using the agent “a signal that they should be very vigilant. It was an observation at one center, but we’re asking our colleagues [at other clinics] to think about being more careful as they review data with their patients.”

He added that future multicenter studies will allow these issues to be assessed more comprehensively. “This was a discovery study; it now needs validation; and maybe the next step would be looking into the mechanism.”

Dr. Silverman pointed out that the Food and Drug Administration–approved label for this type of therapy “allows for somewhat more frequent dosing. So that might be indicated if it’s found that it’s wearing off in an individual. Perhaps they should be treated more frequently?”

“At a minimum, this has raised our vigilance – and we’re interested to see what the feedback will be at the [AAN] meeting,” he added.
 

Real-world data

Commenting on the findings, Eric Klawiter, MD, associate professor of neurology at Harvard Medical School and director of the Multiple Sclerosis and NMO unit at Massachusetts General Hospital, both in Boston, noted that an important study factor was the focus on repopulation to identify specific groups “who may be early repopulators” as it relates to disease activity and disability progression in MS.

“I thought this was a nicely designed study that made good use of real-world data in MS and NMOSD,” added Dr. Klawiter, who was not involved with the research. He pointed out that timing was another interesting aspect of the study. “As we typically use these cell-depleting agents on an ‘every-6-month’ basis, the most pertinent time frame surrounds those that repopulate prior to 6 months.”

If the current study would have shown differences between the Black and White participants at that time point, “I think that would have been most pertinent from a clinical standpoint and a greater opportunity for intervention,” Dr. Klawiter said. “But we saw that, before 4 and 6 months, [the difference] wasn’t significant.”

Still, “after 6 months, the study demonstrates that Black people with MS and NMOSD may repopulate faster,” he added.

“The only real change a clinician could make would be to modify the frequency of the dosing. So if we can identify certain characteristics that would lead you to want to evaluate for the need of redosing sooner, I think that would be useful,” he said.

Specific characteristics identified in previous research include body mass index. “If there are also ethnicity factors, that would be an additional demographic factor that a clinician should pay close attention to,” said Dr. Klawiter.

He noted that his current practice is to check flow cytometry and B-cell counts at the time of a patient’s next infusion. “And if I’m seeing that B-cell levels are repleting at that time point, I am already then making adjustments with their next infusion as to the dosing frequency,” he added.

“This [study] may elucidate some of the potential reasons why we see some people replete their B cells faster than others, but I think additional studies are necessary to make that determination,” Dr. Klawiter concluded.

Genentech provided funding for the study. Dr. Silverman reported no relevant financial relationships. Dr. Klawiter reported having received research funds and consulting fees from Genentech.

“At a minimum, this has raised our vigilance – and we’re interested to see what the feedback will be at the [AAN] meeting,” he added.
 

Real-world data

Commenting on the findings, Eric Klawiter, MD, associate professor of neurology at Harvard Medical School and director of the Multiple Sclerosis and NMO unit at Massachusetts General Hospital, both in Boston, noted that an important study factor was the focus on repopulation to identify specific groups “who may be early repopulators” as it relates to disease activity and disability progression in MS.

“I thought this was a nicely designed study that made good use of real-world data in MS and NMOSD,” added Dr. Klawiter, who was not involved with the research. He pointed out that timing was another interesting aspect of the study. “As we typically use these cell-depleting agents on an ‘every-6-month’ basis, the most pertinent time frame surrounds those that repopulate prior to 6 months.”

If the current study would have shown differences between the Black and White participants at that time point, “I think that would have been most pertinent from a clinical standpoint and a greater opportunity for intervention,” Dr. Klawiter said. “But we saw that, before 4 and 6 months, [the difference] wasn’t significant.”

Still, “after 6 months, the study demonstrates that Black people with MS and NMOSD may repopulate faster,” he added.

“The only real change a clinician could make would be to modify the frequency of the dosing. So if we can identify certain characteristics that would lead you to want to evaluate for the need of redosing sooner, I think that would be useful,” he said.

Specific characteristics identified in previous research include body mass index. “If there are also ethnicity factors, that would be an additional demographic factor that a clinician should pay close attention to,” said Dr. Klawiter.

He noted that his current practice is to check flow cytometry and B-cell counts at the time of a patient’s next infusion. “And if I’m seeing that B-cell levels are repleting at that time point, I am already then making adjustments with their next infusion as to the dosing frequency,” he added.

“This [study] may elucidate some of the potential reasons why we see some people replete their B cells faster than others, but I think additional studies are necessary to make that determination,” Dr. Klawiter concluded.

Genentech provided funding for the study. Dr. Silverman reported no relevant financial relationships. Dr. Klawiter reported having received research funds and consulting fees from Genentech.

A minimally invasive blood test along with artificial intelligence (AI) may flag early-stage Alzheimer’s disease, raising the prospect of early intervention when effective treatments become available.

In a study, investigators used six AI methodologies, including Deep Learning, to assess blood leukocyte epigenomic biomarkers. They found more than 150 genetic differences among study participants with Alzheimer’s disease in comparison with participants who did not have Alzheimer’s disease.

All of the AI platforms were effective in predicting Alzheimer’s disease. Deep Learning’s assessment of intragenic cytosine-phosphate-guanines (CpGs) had sensitivity and specificity rates of 97%.

“It’s almost as if the leukocytes have become a newspaper to tell us, ‘This is what is going on in the brain,’ “ lead author Ray Bahado-Singh, MD, chair of the department of obstetrics and gynecology, Oakland University, Auburn Hills, Mich., said in a news release.

The researchers noted that the findings, if replicated in future studies, may help in providing Alzheimer’s disease diagnoses “much earlier” in the disease process. “The holy grail is to identify patients in the preclinical stage so effective early interventions, including new medications, can be studied and ultimately used,” Dr. Bahado-Singh said.

“This certainly isn’t the final step in Alzheimer’s research, but I think this represents a significant change in direction,” he told attendees at a press briefing.

The findings were published online March 31 in PLOS ONE.
 

Silver tsunami

The investigators noted that Alzheimer’s disease is often diagnosed when the disease is in its later stages, after irreversible brain damage has occurred. “There is currently no cure for the disease, and the treatment is limited to drugs that attempt to treat symptoms and have little effect on the disease’s progression,” they noted.

Coinvestigator Khaled Imam, MD, director of geriatric medicine for Beaumont Health in Michigan, pointed out that although MRI and lumbar puncture can identify Alzheimer’s disease early on, the processes are expensive and/or invasive.

“Having biomarkers in the blood ... and being able to identify [Alzheimer’s disease] years before symptoms start, hopefully we’d be able to intervene early on in the process of the disease,” Dr. Imam said.

It is estimated that the number of Americans aged 85 and older will triple by 2050. This impending “silver tsunami,” which will come with a commensurate increase in Alzheimer’s disease cases, makes it even more important to be able to diagnose the disease early on, he noted.

The study included 24 individuals with late-onset Alzheimer’s disease (70.8% women; mean age, 83 years); 24 were deemed to be “cognitively healthy” (66.7% women; mean age, 80 years). About 500 ng of genomic DNA was extracted from whole-blood samples from each participant.

The researchers used the Infinium MethylationEPIC BeadChip array, and the samples were then examined for markers of methylation that would “indicate the disease process has started,” they noted.

In addition to Deep Learning, the five other AI platforms were the Support Vector Machine, Generalized Linear Model, Prediction Analysis for Microarrays, Random Forest, and Linear Discriminant Analysis.

These platforms were used to assess leukocyte genome changes. To predict Alzheimer’s disease, the researchers also used Ingenuity Pathway Analysis.
 

Significant “chemical changes”

Results showed that the Alzheimer’s disease group had 152 significantly differentially methylated CpGs in 171 genes in comparison with the non-Alzheimer’s disease group (false discovery rate P value < .05).

As a whole, using intragenic and intergenic/extragenic CpGs, the AI platforms were effective in predicting who had Alzheimer’s disease (area under the curve [AUC], ≥ 0.93). Using intragenic markers, the AUC for Deep Learning was 0.99.

“We looked at close to a million different sites, and we saw some chemical changes that we know are associated with alteration or change in gene function,” Dr. Bahado-Singh said.

Altered genes that were found in the Alzheimer’s disease group included CR1L, CTSV, S1PR1, and LTB4R – all of which “have been previously linked with Alzheimer’s disease and dementia,” the researchers noted. They also found the methylated genes CTSV and PRMT5, both of which have been previously associated with cardiovascular disease.

“A significant strength of our study is the novelty, i.e. the use of blood leukocytes to accurately detect Alzheimer’s disease and also for interrogating the pathogenesis of Alzheimer’s disease,” the investigators wrote.

Dr. Bahado-Singh said that the test let them identify changes in cells in the blood, “giving us a comprehensive account not only of the fact that the brain is being affected by Alzheimer’s disease but it’s telling us what kinds of processes are going on in the brain.

“Normally you don’t have access to the brain. This gives us a simple blood test to get an ongoing reading of the course of events in the brain – and potentially tell us very early on before the onset of symptoms,” he added.
 

Cautiously optimistic

During the question-and-answer session following his presentation at the briefing, Dr. Bahado-Singh reiterated that they are at a very early stage in the research and were not able to make clinical recommendations at this point. However, he added, “There was evidence that DNA methylation change could likely precede the onset of abnormalities in the cells that give rise to the disease.”

Coinvestigator Stewart Graham, PhD, director of Alzheimer’s research at Beaumont Health, added that although the initial study findings led to some excitement for the team, “we have to be very conservative with what we say.”

He noted that the findings need to be replicated in a more diverse population. Still, “we’re excited at the moment and looking forward to seeing what the future results hold,” Dr. Graham said.

Dr. Bahado-Singh said that if larger studies confirm the findings and the test is viable, it would make sense to use it as a screen for individuals older than 65. He noted that because of the aging of the population, “this subset of individuals will constitute a larger and larger fraction of the population globally.”
 

Still early days

Commenting on the findings, Heather Snyder, PhD, vice president of medical and scientific relations at the Alzheimer’s Association, noted that the investigators used an “interesting” diagnostic process.

“It was a unique approach to looking at and trying to understand what might be some of the biological underpinnings and using these tools and technologies to determine if they’re able to differentiate individuals with Alzheimer’s disease” from those without Alzheimer’s disease, said Dr. Snyder, who was not involved with the research.

“Ultimately, we want to know who is at greater risk, who may have some of the changing biology at the earliest time point so that we can intervene to stop the progression of the disease,” she said.

She pointed out that a number of types of biomarker tests are currently under investigation, many of which are measuring different outcomes. “And that’s what we want to see going forward. We want to have as many tools in our toolbox that allow us to accurately diagnose at that earliest time point,” Dr. Snyder said.

“At this point, [the current study] is still pretty early, so it needs to be replicated and then expanded to larger groups to really understand what they may be seeing,” she added.

Dr. Bahado-Singh, Dr. Imam, Dr. Graham, and Dr. Snyder have reported no relevant financial relationships.

News of actor/comedian Pete Davidson expressing relief after finally receiving a diagnosis of borderline personality disorder (BPD) prompted a recent Twitter discussion among physicians regarding the ongoing debate on whether or not to tell a patient he or she has this diagnosis.

“I’ve heard from [many] trainees that they were told never to tell a patient they had BPD, but I can hardly think of anything more paternalistic and stigmatizing,” Amy Barnhorst, MD, vice chair of community psychiatry at University of California, Davis, tweeted.

“Most patients, when I explain it to them, have this kind of reaction – they feel relieved and understood,” she added.

“I was told that as well [not to tell] in one of my practicum placements,” one respondent who identified herself as a clinical/forensic psychologist tweeted back. “I said it anyway and the person was relieved there was a name for what they were living with.”

However, others disagreed with Dr. Barnhorst, noting that BPD is a very serious, stigmatizing, and challenging disorder to treat and, because of this, may cause patients to lose hope.

Still, Dr. Barnhorst stands by her position. Although “there is a negative stigma against a diagnosis of BPD,” that idea more often comes from the clinician instead of the patient, she said.

“I’ve never had a patient say, ‘how dare you call me that!’ like it was an insult,” she said in an interview. Not disclosing a diagnosis “is like you’re not trusting a patient to be a reasonable adult human about this.”
 

‘Hard diagnosis’

Although BPD is a “hard diagnosis, we would never withhold a diagnosis of cancer or liver disease or something else we knew patients didn’t want but that we were going to try and treat them for,” said Dr. Barnhorst.

BPD is linked to significant morbidity because of its common association with comorbid conditions, such as major depressive disorder, substance use disorders, and dysthymia. A history of self-harm is present in 70%-75% of these patients and some estimates suggest up to 9% of individuals with BPD die by suicide.

In an article published in Innovations in Clinical Neuroscience investigators discussed “ethical and clinical questions psychiatrists should consider” when treating BPD, including whether a diagnosis should be shared with a patient.

After such a diagnosis a patient may “react intensely in negative ways and these responses may be easily triggered,” the researchers wrote.

“A propensity that will likely cause psychiatrists anguish, however, is BPD patients’ increased likelihood of attempting suicide,” they added. Part of the problem has been that, in the past, it was thought that a BPD prognosis was untreatable. However, the researchers note that is no longer the case.

Still, Kaz Nelson, MD, associate professor of psychiatry and behavioral sciences at the University of Minnesota, Minneapolis, has labeled BPD a so-called “asterisk” disorder.  

As she wrote in a recent blog, “We tell patients when they meet criteria for a medical diagnosis.* We show compassion and nonjudgmentalism to patients.* We do not discriminate against patients.*” However, the asterisk for each of these statements is: *Except for those with BPD.
 

Ongoing debate

Starting around the 1980s, the DSM listed personality disorders under the No. 2 Axis, which is for conditions with symptoms that are “not mitigatable,” said Dr. Nelson.

“It really started as well-meaning therapists who care about their patients who wanted to develop some precision in understanding people, and them starting to notice some patterns that can get in the way of optimal function,” she said in an interview.

The thought was not to disclose these diagnoses “because that was for you to understand, and for the patient to discover these patterns over time in the course of your work together,” Dr. Nelson added.

Although treatment for BPD used to be virtually nonexistent, there is now hope – especially with dialectic-behavior therapy (DBT), which uses mindfulness to teach patients how to control emotions and improve relationships.

According to the National Education Alliance for BPD, other useful treatments include mentalization-based therapy, transference-focused therapy, and “good psychiatric management.” Although there are currently no approved medications for BPD, some drugs are used to treat comorbid conditions such as depression or anxiety.

“We now know that people recover, and the whole paradigm has been turned on its head,” Dr. Nelson said. For example, “we no longer categorize these things as treatable or untreatable, which was a very positive move.”

So why is the field still debating the issue of diagnosis disclosure?

“To this day there are different psychiatrists and some medical school curricula that continue to teach that personality disorders are long-term, fixed, and nontreatable – and that it’s kind of disparaging to give this kind of diagnosis to a patient,” Dr. Nelson said.

Dr. Nelson, also the vice chair for education at the University of Minnesota, Minneapolis, medical school, reported that there “we acknowledge BPD’s painful history and that there are these misconceptions. They’re going to be on the front line of combating discrimination and the idea that if you see a patient with possible BPD coming you should run. That’s just unacceptable.”

Dr. Nelson noted that the idea of disclosing a BPD diagnosis is less controversial now than in the past, but “the whole thing is still under debate, and treatment guidelines [on BPD] are old and expired.”

Criteria for BPD were not updated when the DSM-5 was published in 2013, and that needs to be fixed, Dr. Nelson added. “In the meantime, we’re trying to get the word out that it’s okay to interact with people about the diagnosis, discuss treatment plans, and manage it as one would with any other psychiatric or medical illness.”
 

An evolution, not a debate

Paul Appelbaum, MD, past president of the American Psychiatric Association and current chair of the organization’s DSM steering committee, said in an interview that he hasn’t been involved in any recent debate on this issue.

“I think practice has changed to the point where the general practice is to discuss patient diagnoses with [patients] openly. Patients appreciate that and psychiatrists have come to see the advantages of it,” said Dr. Appelbaum, a professor of psychiatry, medicine, and law at Columbia University, New York.

Dr. Appelbaum noted that patients also increasingly have access to their medical records, “so the reality is that it’s no longer possible in many cases to withhold a diagnosis.”

“I don’t think it’s a debate; I think it’s been an evolution,” he said. “Maybe not everyone is entirely on board yet but there has been a sea change in psychiatric practices.”

Asked whether there needs to be some type of guideline update or statement released by the APA regarding BPD, Dr. Appelbaum said he doesn’t think the overall issue is BPD specific but applies to all psychiatric diagnoses.

“To the extent that there are still practitioners today that are telling students or residents [not to disclose], I would guess that they were trained a very long time ago and have not adapted to the new world,” he said.

“I don’t want to speak for the APA, but speaking for myself: I certainly encourage residents that I teach to be open about a diagnosis. It’s not just clinically helpful in some cases, it’s also ethically required from the perspective of allowing patients to make appropriate decisions about their treatment. And arguably it’s legally required as well, as part of the informed consent requirement,” Dr. Appelbaum said.

Regarding DSM updates, he noted that the committee “looks to the field to propose to us additions or changes to the DSM that are warranted by data that have been gathered since the DSM-5 came out.” There is a process set up on the DSM’s website to review such proposals.

In addition, Dr. Appelbaum said that there have been discussions about using a new model “that focuses on dimensions rather than on discreet categories” in order to classify personality disorders.

“There’s a group out there that is formulating a proposal that they will submit to us” on this, he added. “That’s the major discussion that is going on right now and it would clearly have implications for borderline as well as all the other personality disorders.”

In a statement, the APA said practice guidelines for BPD are currently under review and that the organization does not have a “position statement” on BPD for clinicians. The last update to its guideline was in the early 2000s.

In an article published in Innovations in Clinical Neuroscience investigators discussed “ethical and clinical questions psychiatrists should consider” when treating BPD, including whether a diagnosis should be shared with a patient.

After such a diagnosis a patient may “react intensely in negative ways and these responses may be easily triggered,” the researchers wrote.

“A propensity that will likely cause psychiatrists anguish, however, is BPD patients’ increased likelihood of attempting suicide,” they added. Part of the problem has been that, in the past, it was thought that a BPD prognosis was untreatable. However, the researchers note that is no longer the case.

Still, Kaz Nelson, MD, associate professor of psychiatry and behavioral sciences at the University of Minnesota, Minneapolis, has labeled BPD a so-called “asterisk” disorder.  

As she wrote in a recent blog, “We tell patients when they meet criteria for a medical diagnosis.* We show compassion and nonjudgmentalism to patients.* We do not discriminate against patients.*” However, the asterisk for each of these statements is: *Except for those with BPD.
 

Ongoing debate

Starting around the 1980s, the DSM listed personality disorders under the No. 2 Axis, which is for conditions with symptoms that are “not mitigatable,” said Dr. Nelson.

“It really started as well-meaning therapists who care about their patients who wanted to develop some precision in understanding people, and them starting to notice some patterns that can get in the way of optimal function,” she said in an interview.

The thought was not to disclose these diagnoses “because that was for you to understand, and for the patient to discover these patterns over time in the course of your work together,” Dr. Nelson added.

Although treatment for BPD used to be virtually nonexistent, there is now hope – especially with dialectic-behavior therapy (DBT), which uses mindfulness to teach patients how to control emotions and improve relationships.

According to the National Education Alliance for BPD, other useful treatments include mentalization-based therapy, transference-focused therapy, and “good psychiatric management.” Although there are currently no approved medications for BPD, some drugs are used to treat comorbid conditions such as depression or anxiety.

“We now know that people recover, and the whole paradigm has been turned on its head,” Dr. Nelson said. For example, “we no longer categorize these things as treatable or untreatable, which was a very positive move.”

So why is the field still debating the issue of diagnosis disclosure?

“To this day there are different psychiatrists and some medical school curricula that continue to teach that personality disorders are long-term, fixed, and nontreatable – and that it’s kind of disparaging to give this kind of diagnosis to a patient,” Dr. Nelson said.

Dr. Nelson, also the vice chair for education at the University of Minnesota, Minneapolis, medical school, reported that there “we acknowledge BPD’s painful history and that there are these misconceptions. They’re going to be on the front line of combating discrimination and the idea that if you see a patient with possible BPD coming you should run. That’s just unacceptable.”

Dr. Nelson noted that the idea of disclosing a BPD diagnosis is less controversial now than in the past, but “the whole thing is still under debate, and treatment guidelines [on BPD] are old and expired.”

Criteria for BPD were not updated when the DSM-5 was published in 2013, and that needs to be fixed, Dr. Nelson added. “In the meantime, we’re trying to get the word out that it’s okay to interact with people about the diagnosis, discuss treatment plans, and manage it as one would with any other psychiatric or medical illness.”
 

An evolution, not a debate

Paul Appelbaum, MD, past president of the American Psychiatric Association and current chair of the organization’s DSM steering committee, said in an interview that he hasn’t been involved in any recent debate on this issue.

“I think practice has changed to the point where the general practice is to discuss patient diagnoses with [patients] openly. Patients appreciate that and psychiatrists have come to see the advantages of it,” said Dr. Appelbaum, a professor of psychiatry, medicine, and law at Columbia University, New York.

Dr. Appelbaum noted that patients also increasingly have access to their medical records, “so the reality is that it’s no longer possible in many cases to withhold a diagnosis.”

“I don’t think it’s a debate; I think it’s been an evolution,” he said. “Maybe not everyone is entirely on board yet but there has been a sea change in psychiatric practices.”

Asked whether there needs to be some type of guideline update or statement released by the APA regarding BPD, Dr. Appelbaum said he doesn’t think the overall issue is BPD specific but applies to all psychiatric diagnoses.

“To the extent that there are still practitioners today that are telling students or residents [not to disclose], I would guess that they were trained a very long time ago and have not adapted to the new world,” he said.

“I don’t want to speak for the APA, but speaking for myself: I certainly encourage residents that I teach to be open about a diagnosis. It’s not just clinically helpful in some cases, it’s also ethically required from the perspective of allowing patients to make appropriate decisions about their treatment. And arguably it’s legally required as well, as part of the informed consent requirement,” Dr. Appelbaum said.

Regarding DSM updates, he noted that the committee “looks to the field to propose to us additions or changes to the DSM that are warranted by data that have been gathered since the DSM-5 came out.” There is a process set up on the DSM’s website to review such proposals.

In addition, Dr. Appelbaum said that there have been discussions about using a new model “that focuses on dimensions rather than on discreet categories” in order to classify personality disorders.

“There’s a group out there that is formulating a proposal that they will submit to us” on this, he added. “That’s the major discussion that is going on right now and it would clearly have implications for borderline as well as all the other personality disorders.”

In a statement, the APA said practice guidelines for BPD are currently under review and that the organization does not have a “position statement” on BPD for clinicians. The last update to its guideline was in the early 2000s.

News of actor/comedian Pete Davidson expressing relief after finally receiving a diagnosis of borderline personality disorder (BPD) prompted a recent Twitter discussion among physicians regarding the ongoing debate on whether or not to tell a patient he or she has this diagnosis.

“I’ve heard from [many] trainees that they were told never to tell a patient they had BPD, but I can hardly think of anything more paternalistic and stigmatizing,” Amy Barnhorst, MD, vice chair of community psychiatry at University of California, Davis, tweeted.

“Most patients, when I explain it to them, have this kind of reaction – they feel relieved and understood,” she added.

“I was told that as well [not to tell] in one of my practicum placements,” one respondent who identified herself as a clinical/forensic psychologist tweeted back. “I said it anyway and the person was relieved there was a name for what they were living with.”

However, others disagreed with Dr. Barnhorst, noting that BPD is a very serious, stigmatizing, and challenging disorder to treat and, because of this, may cause patients to lose hope.

Still, Dr. Barnhorst stands by her position. Although “there is a negative stigma against a diagnosis of BPD,” that idea more often comes from the clinician instead of the patient, she said.

“I’ve never had a patient say, ‘how dare you call me that!’ like it was an insult,” she said in an interview. Not disclosing a diagnosis “is like you’re not trusting a patient to be a reasonable adult human about this.”
 

‘Hard diagnosis’

Although BPD is a “hard diagnosis, we would never withhold a diagnosis of cancer or liver disease or something else we knew patients didn’t want but that we were going to try and treat them for,” said Dr. Barnhorst.

BPD is linked to significant morbidity because of its common association with comorbid conditions, such as major depressive disorder, substance use disorders, and dysthymia. A history of self-harm is present in 70%-75% of these patients and some estimates suggest up to 9% of individuals with BPD die by suicide.

Results from a phase 2 placebo-controlled trial of the investigational antiamyloid drug donanemab show that the novel agent met the primary outcome of slowing cognitive decline in patients with early symptomatic Alzheimer’s disease (AD). 

Results from the TRAILBLAZER-ALZ trial were presented at the 2021 International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD) and were simultaneously published online March 13 in the New England Journal of Medicine.

As previously reported by Medscape Medical News, topline results showed that donanemab slowed cognitive decline by 32% on the Integrated AD Rating Scale (iADRS) from baseline to 76 weeks relative to placebo.

The newly released detailed findings showed that “the use of donanemab resulted in a better composite score for cognition and for the ability to perform activities of daily living than placebo at 76 weeks, although results for secondary outcomes were mixed,” the investigators, with first author Mark A. Mintun, MD, an employee of Eli Lilly, reported.   

Results revealed improvement in scores on the Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and the 13-item cognitive subscale of the AD Assessment Scale (ADAS-Cog13), but the differences between the two treatment groups were not significant. In addition, score changes on the AD Cooperative Study–Instrumental Activities of Daily Inventory (ADCS-iADL) and the Mini-Mental State Examination (MMSE) were not “substantial.”

However, the donanemab group did show an 85-centiloid greater reduction in amyloid plaque level at 76 weeks, as shown on PET, compared with the placebo group.
 

Proof of concept?

The humanized antibody donanemab, which was previously known as LY3002813, targets a modified form of deposited amyloid-beta (A-beta) peptide called N3pG.

The randomized, placebo-controlled, double-blind TRAILBLAZER-ALZ trial, which was described as a “phase 2 proof of concept trial” in the AD/PD program, was conducted at 56 sites in the United States and Canada and included 257 patients between the ages of 60 and 85 years (52% were women). PET confirmed tau and amyloid deposition in all participants.

The active treatment group (n = 131) was randomly assigned to receive donanemab 700 mg for three doses; after that, treatment was bumped up to 1,400 mg. Both the donanemab and placebo groups (n = 126) received treatment intravenously every 4 weeks for up to 72 weeks.

Participants also underwent F-florbetapir and F-flortaucipir PET scans at various timepoints and completed a slew of cognitive tests.

The study’s primary outcome measure was change between baseline and 76 weeks post treatment on composite score for cognition, as measured by the iADRS. The iADRS combines the ADAS-Cog13 and the ADCS-iADL.

This measure ranges from 0 to 144, with lower scores associated with greater cognitive impairment. Both treatment groups had an iADRS score of 106 at baseline.
 

More research needed

Results showed that the score change from baseline on the iADRS was –6.86 for the active treatment group vs –10.06 for the placebo group (group difference, 3.2; 95% confidence interval [CI], 0.12-6.27; P = .04). Although significant, “the trial was powered to show a 6-point difference,” which was not met, the investigators note.

Differences in score changes from baseline to 76 weeks for the treatment vs. placebo groups on the following secondary outcome measures were:

• CDR-SB: –0.36 (95% CI, –0.83 to –0.12).
• ADAS-Cog13: –1.86 (95% CI, –3.63 to –0.09).
• ADCS-iADL: 1.21 (95% CI, –0.77 to 3.2).
• MMSE: 0.64 (95% CI, –0.4 to 1.67).

The CDR-SB was designated as the first secondary outcome, and because it did not show a significant between-group difference, “the hierarchy failed and no definite conclusions can be drawn from data regarding the differences between groups in the change in the ADAS-Cog13,” the investigators wrote.

In addition, the differences in scores on the latter two secondary outcomes were not “substantial,” they reported.

However, at 76 weeks, the donanemab group showed a reduction of 84.13 centiloids in amyloid plaque level vs. an increase of 0.93 centiloids in the placebo group (between-group difference, 85.06 centiloids). At 24 weeks, the active-treatment group had a 67.83-centiloids greater reduction vs. the placebo group.

In addition, 40%, 59.8%, and 67.8% of the donanemab group achieved “amyloid-negative status” at 24, 52, and 76 weeks, respectively. Amyloid-negative status was defined as an amyloid plaque level of less than 24.1 centiloids.

Total incidence of death or serious adverse events did not differ significantly between the groups. However, the donanemab group had significantly more reports of ARIA-E compared with the placebo group (26.7% vs. 0.8%).

Overall, the researchers noted that more trials of longer duration with larger patient numbers are warranted “to further determine the efficacy and safety of donanemab” in AD.
 

Positive signal?

In a statement, Maria Carrillo, PhD, chief science officer for the Alzheimer’s Association, said the organization “is encouraged by this promising data.

“It is the first phase 2 Alzheimer’s trial to show positive results on a primary outcome measure related to memory and thinking,” Dr. Carrillo said. However, “more work needs to be done on this experimental drug therapy.”

Dr. Carrillo noted that because the trial was moderately sized and only 180 participants completed the study, “we look forward to the results of a second, larger phase 2 trial of this drug.”

Still, she added, there were several “novel and innovative aspects” in the way the study was conducted noting that it showcases the evolution of AD research.

“I’m hopeful for the future,” Dr. Carrillo said.

Also commenting on the results, Howard Fillit, MD, neuroscientist and founding executive director and chief science officer of the Alzheimer’s Drug Discovery Foundation, said the study showed “the pharmacology works” and that the drug did what it was supposed to do in terms of removing A-beta plaque.

“It also gave us a signal in a relatively small phase 2 study that there might be a modest cognitive benefit,” said Dr. Fillit, who was not involved with the research.

He noted that although the rate of decline slowing was statistically significant it remains to be seen whether this is clinically meaningful, particularly in light of the fact that the secondary outcome results were mixed.  

“Basically, it was a positive study that probably needs to be followed by another, much larger study to get us to really see the benefit,” Dr. Fillit said.

Dr. Mintun is an employee of Eli Lilly, which funded the study. Dr. Carrillo and Dr. Fillit have reported no relevant financial relationships.

Overall, the researchers noted that more trials of longer duration with larger patient numbers are warranted “to further determine the efficacy and safety of donanemab” in AD.
 

Positive signal?

In a statement, Maria Carrillo, PhD, chief science officer for the Alzheimer’s Association, said the organization “is encouraged by this promising data.

“It is the first phase 2 Alzheimer’s trial to show positive results on a primary outcome measure related to memory and thinking,” Dr. Carrillo said. However, “more work needs to be done on this experimental drug therapy.”

Dr. Carrillo noted that because the trial was moderately sized and only 180 participants completed the study, “we look forward to the results of a second, larger phase 2 trial of this drug.”

Still, she added, there were several “novel and innovative aspects” in the way the study was conducted noting that it showcases the evolution of AD research.

“I’m hopeful for the future,” Dr. Carrillo said.

Also commenting on the results, Howard Fillit, MD, neuroscientist and founding executive director and chief science officer of the Alzheimer’s Drug Discovery Foundation, said the study showed “the pharmacology works” and that the drug did what it was supposed to do in terms of removing A-beta plaque.

“It also gave us a signal in a relatively small phase 2 study that there might be a modest cognitive benefit,” said Dr. Fillit, who was not involved with the research.

He noted that although the rate of decline slowing was statistically significant it remains to be seen whether this is clinically meaningful, particularly in light of the fact that the secondary outcome results were mixed.  

“Basically, it was a positive study that probably needs to be followed by another, much larger study to get us to really see the benefit,” Dr. Fillit said.

Dr. Mintun is an employee of Eli Lilly, which funded the study. Dr. Carrillo and Dr. Fillit have reported no relevant financial relationships.

An eye-opening moment during March 7’s Meghan Markle/Prince Harry interview with Oprah Winfrey was Markle’s admission that, before the royal couple moved from the U.K., she was suicidal and had nowhere to turn for help.

For health care practitioners, this has resurfaced the debate over universal suicidality screening and discussion about what should happen when patients screen positive.

The American Psychiatric Association reports suicide is the 10th leading cause of death in the United States, but the second leading cause of death in people age 10-34 years old.

The latest data from the Centers for Disease Control and Prevention show that, in 2019, suicide rates dropped for the first time in 14 years. However, it is widely expected that, in the face of the COVID-19 pandemic and its associated isolation, loneliness, and stress, the next round of data will show a surge in suicide deaths.

Individuals’ mental health “has been deteriorating” since COVID-19, said Ludmila De Faria, MD, chair of the APA’s Committee on Women’s Mental Health.

“I can see it in my office. People who didn’t necessarily complain about anxiety and depression before or who had been stable for many years are decompensating now,” Dr. De Faria said in an interview.

Although other parts of the interview may have been controversial, said Dr. De Faria, Markle’s disclosure has opened up a much-needed discussion.

“I’m all for people talking about mental health, and I commend [Markle] for sharing her struggle and putting it out there,” she added.

In a perfect world, she noted, there would be universal suicide screening by all medical professionals.

However, Dr. De Faria, associate clinical professor of psychiatry, University of Florida, Gainesville, acknowledged that from a resource standpoint this is not a pragmatic solution.

Primary care physicians are often the frontline defense for suicide prevention, noted Mona Masood, DO, a Philadelphia-area psychiatrist and founder and chief organizer of the Physician Support Line, a free mental health hotline exclusively for doctors staffed by volunteer psychiatrists.   

“I believe our general practitioner colleagues, our family medicine colleagues are the ones who are going to be seeing the majority of mental health concerns or illnesses because of the stigma that is often there from seeing a psychiatrist,” Dr. Masood said in an interview.

Dr. De Faria noted that the Patient Health Questionnaire-2 (PHQ-2) for mental health offers a simple screen that includes two key questions. It asks: Over the last 2 weeks, how often have you been bothered by the following problems?

• Little interest or pleasure in doing things.
• Feeling down, depressed, or hopeless.

However, both Dr. De Faria and Dr. Masood emphasized that individualized follow-up questions and follow-up care are equally important.

Unlike Dr. De Faria, who prefers universal screening but understands the challenges of implementing it, Dr. Masood favors targeted screening.

“For physicians, the whole point of what we do is to save lives. To talk to somebody about the complete opposite and to ask, ‘Are you planning on ending your life?’ is very jarring. But for the patient, that may be their only outlet. A primary care provider may be the only professional that they talk to about their mental health,” said Dr. Masood.

Patients can easily say “no” to suicidal ideation questions from a general screen, but targeted, probing questions let patients know that they’re being heard and seen beyond their physical examination, she added.

She also suggested that clinicians ask open-ended questions of those patients who are struggling.

Dr. Masood noted that having a plan in place before screening a patient is especially key.

“I’d argue that one of the subconscious reasons why so many doctors do not ask the question [about suicidality] is because if you ask it, you have to be ready for the answer and to know what you’d do,” she said.

All primary care physicians should have “mental health professionals as resources in your back pocket” in order to have a referral ready to give to patients in need, she said.

“Outside of your clinic time, have a rapport with your local psychiatrist or therapist and know where to send someone who is suicidal,” Dr. Masood said. “Know what is in your local area so you’ll already know how to implement your plan.”

Dr. Masood also recommended:

• Informing staff about protocols for patients with suicidal thoughts who need to go to the hospital for evaluation.
• Creating a safe space in the clinic/office, such as an unused exam room, where patients can wait for next steps.
• Having staff inform a patient’s emergency contact about the situation.
• Trying for a “warm handoff,” where the emergency contact takes the patient to the nearest crisis center and having staff call ahead to let them know to expect the patient.
• If the patient has no emergency contact, following your state’s involuntary crisis response protocol, which involves calling 911 for emergency services.  

In addition, the APA’s suicide prevention page includes a long list of helpful resources for patients, families, and physicians.

Posttraumatic stress disorder may occur in up to a third of patients who recover from severe COVID-19 infection, new research suggests.

A study of more than 300 patients who presented to the emergency department with the virus showed a 30.2% prevalence for PTSD 30-120 days after COVID recovery.

Factors linked to higher rates of PTSD included experiencing delirium or agitation during the acute COVID phase or having persistent medical symptoms after hospitalization. 

Additional diagnoses, such as depressive and hypomanic episodes and generalized anxiety disorder (GAD), were also present in some of the survivors.

“Previous coronavirus epidemics were associated with PTSD diagnoses in postillness stages, with meta-analytic findings indicating a prevalence of 32.2%,” write the investigators, led by Delfina Janiri, MD, department of psychiatry, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome.

However, data focused specifically on COVID-19 have been “piecemeal,” they add.

The findings were published online Feb. 18 in a research letter in JAMA Psychiatry.
 

A traumatic event

From April to October 2020, the researchers assessed 381 consecutive patients (100% white; 56.4% men; mean age, 55.3 years) who presented to the ED and subsequently participated in a health check at the Fondazione Policlinico Universitario Agostino Gemelli.

The mean length of stay for the 309 patients hospitalized with severe COVID-19 was 18.4 days.

Results showed that 115 participants (30.2%) had PTSD, based on DSM-5 criteria, and 55.7% of the women had the disorder. Additional diagnoses found in the full patient population included:

• Depressive episodes (17.3%).
• GAD (7%).
• Hypomanic episodes (0.7%).
• Psychotic disorders (0.2%).

Patients with PTSD had higher rates than those without PTSD of a previous history of psychiatric disorders (34.8% vs. 20.7%; P = .003) and of delirium or agitation during hospitalization, as assessed with the Confusion Assessment Method (16.5% vs. 6.4%; P = .002).

In addition, 62.6% of those with PTSD had three or more persistent COVID-19 symptoms vs. 37.2% of their counterparts without PTSD (P < .001).

After logistic regression analyses, significant factors associated with a PTSD diagnosis were persistent medical symptoms (P = .002), delirium or agitation (P = .02), and being female (P = .02).

The investigators note that their results are “in line” with findings reported in research examining other traumatic events. This includes about 30% of Hurricane Katrina survivors who experienced PTSD, as did around 25% of survivors of the 2011 “Great Japan Earthquake and Tsunami.”

Study limitations cited include the “relatively small” size of the patient population, that it focused on only one participating center, and that it didn’t include a control group of non-COVID patients who reported to the ED.

“Further longitudinal studies are needed to tailor therapeutic interventions and prevention strategies,” the researchers write.

Dr. Janiri and four of the five other authors have disclosed no relevant financial relationships. The other author, Gabriele Sani, MD, reported having received personal fees from Angelini Spa, Janssen, and Lundbeck outside the submitted work.

The Food and Drug Administration has approved the antisense oligonucleotide casimersen (Amondys 45, Sarepta Therapeutics) injection for the treatment of patients with Duchenne muscular dystrophy (DMD) plus a rare DMD mutation, the agency has announced. 

This particular mutation of the DMD gene “is amenable to exon 45 skipping,” the FDA noted in a press release. The agency added that this is its first approval of a targeted treatment for patients with the mutation.

“Developing drugs designed for patients with specific mutations is a critical part of personalized medicine,” Eric Bastings, MD, deputy director of the Office of Neuroscience at the FDA’s Center for Drug Evaluation and Research, said in a statement.

The approval was based on results from a 43-person randomized controlled trial. Patients who received casimersen had a greater increase in production of the muscle-fiber protein dystrophin compared with their counterparts who received placebo.
 

Approved – with cautions

The FDA noted that DMD prevalence worldwide is about 1 in 3,600 boys – although it can also affect girls in rare cases. Symptoms of the disorder are commonly first observed around age 3 years but worsen steadily over time. DMD gene mutations lead to a decrease in dystrophin.

As reported by Medscape Medical News in August, the FDA approved viltolarsen (Viltepso, NS Pharma) for the treatment of DMD in patients with a confirmed mutation amenable to exon 53 skipping, following approval of golodirsen injection (Vyondys 53, Sarepta Therapeutics) for the same indication in December 2019.  

The DMD gene mutation that is amenable to exon 45 skipping is present in about 8% of patients with DMD.

The trial that carried weight with the FDA included 43 male participants with DMD aged 7-20 years. All were confirmed to have the exon 45-skipping gene mutation and all were randomly assigned 2:1 to received IV casimersen 30 mg/kg or matching placebo.

Results showed that, between baseline and 48 weeks post treatment, the casimersen group showed a significantly higher increase in levels of dystrophin protein than in the placebo group.

Upper respiratory tract infections, fever, joint and throat pain, headache, and cough were the most common adverse events experienced by the active-treatment group.

Although the clinical studies assessing casimersen did not show any reports of kidney toxicity, the adverse event was observed in some nonclinical studies. Therefore, clinicians should monitor kidney function in any patient receiving this treatment, the FDA recommended.

Overall, “the FDA has concluded that the data submitted by the applicant demonstrated an increase in dystrophin production that is reasonably likely to predict clinical benefit” in this patient population, the agency said in its press release.

However, it noted that definitive clinical benefits such as improved motor function were not “established.”

“In making this decision, the FDA considered the potential risks associated with the drug, the life-threatening and debilitating nature of the disease, and the lack of [other] available therapy,” the agency said.

It added that the manufacturer is currently conducting a multicenter study focused on the safety and efficacy of the drug in ambulatory patients with DMD.

The FDA approved casimersen using its Accelerated Approval pathway, granted Fast Track and Priority Review designations to its applications, and gave the treatment Orphan Drug designation.

The approval was based on results from a 43-person randomized controlled trial. Patients who received casimersen had a greater increase in production of the muscle-fiber protein dystrophin compared with their counterparts who received placebo.
 

Approved – with cautions

The FDA noted that DMD prevalence worldwide is about 1 in 3,600 boys – although it can also affect girls in rare cases. Symptoms of the disorder are commonly first observed around age 3 years but worsen steadily over time. DMD gene mutations lead to a decrease in dystrophin.

As reported by Medscape Medical News in August, the FDA approved viltolarsen (Viltepso, NS Pharma) for the treatment of DMD in patients with a confirmed mutation amenable to exon 53 skipping, following approval of golodirsen injection (Vyondys 53, Sarepta Therapeutics) for the same indication in December 2019.  

The DMD gene mutation that is amenable to exon 45 skipping is present in about 8% of patients with DMD.

The trial that carried weight with the FDA included 43 male participants with DMD aged 7-20 years. All were confirmed to have the exon 45-skipping gene mutation and all were randomly assigned 2:1 to received IV casimersen 30 mg/kg or matching placebo.

Results showed that, between baseline and 48 weeks post treatment, the casimersen group showed a significantly higher increase in levels of dystrophin protein than in the placebo group.

Upper respiratory tract infections, fever, joint and throat pain, headache, and cough were the most common adverse events experienced by the active-treatment group.

Although the clinical studies assessing casimersen did not show any reports of kidney toxicity, the adverse event was observed in some nonclinical studies. Therefore, clinicians should monitor kidney function in any patient receiving this treatment, the FDA recommended.

Overall, “the FDA has concluded that the data submitted by the applicant demonstrated an increase in dystrophin production that is reasonably likely to predict clinical benefit” in this patient population, the agency said in its press release.

However, it noted that definitive clinical benefits such as improved motor function were not “established.”

“In making this decision, the FDA considered the potential risks associated with the drug, the life-threatening and debilitating nature of the disease, and the lack of [other] available therapy,” the agency said.

It added that the manufacturer is currently conducting a multicenter study focused on the safety and efficacy of the drug in ambulatory patients with DMD.

The FDA approved casimersen using its Accelerated Approval pathway, granted Fast Track and Priority Review designations to its applications, and gave the treatment Orphan Drug designation.

Repeated intravenous infusions of ketamine provide rapid relief for patients with posttraumatic stress disorder, new research suggests.

In what investigators are calling the first randomized controlled trial of repeated ketamine administration for chronic PTSD, 30 patients received six infusions of ketamine or midazolam (used as a psychoactive placebo) over 2 consecutive weeks. 

Between baseline and week 2, those receiving ketamine showed significantly greater improvement than those receiving midazolam. Total scores on the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) for the first group were almost 12 points lower than the latter group at week 2, meeting the study’s primary outcome measure.

In addition, 67% vs. 20% of the patients, respectively, were considered to be treatment responders; time to loss of response for those in the ketamine group was 28 days.

Although the overall findings were as expected, “what was surprising was how robust the results were,” lead author Adriana Feder, MD, associate professor of psychiatry, Icahn School of Medicine, Mount Sinai, New York, told this news organization.

It was also a bit surprising that, in a study of just 30 participants, “we were able to show such a clear difference” between the two treatment groups, said Dr. Feder, who is also a coinventor on issued patents for the use of ketamine as therapy for PTSD, and codirector of the Ehrenkranz Lab for the Study of Human Resilience at Mount Sinai.

The findings were published online Jan. 5 in the American Journal of Psychiatry.
 

Unmet need

Ketamine is a glutamate N-methyl-D-aspartate (NMDA) receptor antagonist that was first approved by the U.S. Food and Drug Administration for anesthetic use in 1970. It has also been shown to be effective for treatment-resistant depression.

PTSD has a lifetime prevalence of about 6% in the United States. “While trauma-focused psychotherapies have the most empirical support, they are limited by significant rates of nonresponse, partial response, and treatment dropout,” the investigators write. Also, there are “few available pharmacotherapies for PTSD, and their efficacy is insufficient,” they add.  

“There’s a real need for new treatment interventions that are effective for PTSD and also work rapidly, because it can take weeks to months for currently available treatments to work for PTSD,” Dr. Feder said.

The researchers previously conducted a “proof-of-concept” randomized controlled trial of single infusions of ketamine for chronic PTSD. Results published in 2014 in JAMA Psychiatry showed significant reduction in PTSD symptoms 24 hours after infusion.

For the current study, the investigative team wanted to assess whether ketamine was viable as a longer-term treatment.

“We were encouraged by our initial promising findings” of the earlier trial, Dr. Feder said. “We wanted to do the second study to see if ketamine really works for PTSD, to see if we could replicate the rapid improvement and also examine whether a course of six infusions over 2 weeks could maintain the improvement.”

Thirty patients (aged 18-70; mean age, 39 years) with chronic PTSD from civilian or military trauma were enrolled (mean PTSD duration, 15 years).

The most cited primary trauma was sexual assault or molestation (n = 13), followed by physical assault or abuse (n = 8), witnessing a violent assault or death (n = 4), witnessing the 9/11 attacks (n = 3), and combat exposure (n = 2).

During the 2-week treatment phase, half of the patients were randomly assigned to receive six infusions of ketamine hydrochloride at a dose of 0.5 mg/kg (86.7% women; mean CAPS-5 score, 42), while the other half received six infusions of midazolam at a dose of 0.045 mg/kg (66.7% women; mean CAPS-5 score, 40).

In addition to the primary outcome measure of 2-week changes on the CAPS-5, secondary outcomes included score changes on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Impact of Event Scale-Revised (IES-R).

Treatment response was defined as a 30% or more improvement in symptoms on the CAPS-5. A number of measures were also used to assess potential treatment-related adverse events (AEs).
 

Safe, effective

Results showed significantly lower total CAPS-5 scores for the ketamine group vs. the midazolam group at week 1 (score difference, 8.8 points; P = .03) and at week 2 (score difference, 11.88 points; P = .004).

Those receiving ketamine also showed improvements in three of the four PTSD symptom clusters on the CAPS-5: avoidance (P < .0001), negative mood and cognitions (P = .02), and intrusions (P = .03). The fourth symptom cluster – arousal and reactivity – did not show a significant improvement.

In addition, the ketamine group showed significantly greater improvement scores on the MADRS at both week 1 and week 2.

Treatment response at 2 weeks was achieved by 10 members of the ketamine group and by three members of the midazolam group (P = .03).

Secondary analyses showed rapid improvement in the treatment responders within the ketamine group, with a mean change of 26 points on the total IES-R score between baseline and 24 hours after their first infusion, and a mean change of 13.4 points on the MADRS total past-24-hour score, a 53% improvement on average.

“A response at 2 weeks is very rapid but they got better sometimes within the first day,” Dr. Feder noted.

There were no serious AEs reported. Although some dissociative symptoms occurred during ketamine infusions, with the highest levels reported at the end of the infusion, these symptoms had resolved by the next assessment, conducted 2 hours after infusion.

The most frequently reported AE in the ketamine group, compared with midazolam, after the start of infusions was blurred vision (53% vs. 0%), followed by dizziness (33% vs. 13%), fatigue (33% vs. 87%), headache (27% vs. 13%), and nausea or vomiting (20% vs. 7%).
 

‘Large-magnitude improvement’

The overall findings show that, in this patient population, “repeated intravenous ketamine infusions administered over 2 weeks were associated with a large-magnitude, clinically significant improvement in PTSD symptoms,” the investigators write.

The results “were very satisfying,” added Dr. Feder. “It was heartening also to hear what some of the participants would say. Some told us about how their symptoms and feelings had changed during the course of treatment with ketamine, where they felt stronger and better able to cope with their trauma and memories.”

She noted, however, that this was not a study designed to specifically assess ketamine in treatment-resistant PTSD. “Some patients had had multiple treatments before that hadn’t worked, while others had not received treatment before. Efficacy for treatment-resistant PTSD is an important question for future research,” Dr. Feder said.

Other areas worth future exploration include treatment efficacy in patients with different types of trauma and whether outcomes can last longer in patients receiving ketamine plus psychotherapy treatment, she noted.

“I don’t want to ignore the fact that currently available treatments work for a number of people with chronic PTSD. But because there are many more for whom [the treatments] don’t work, or they’re insufficiently helped by those treatments, this is certainly one potentially very promising approach that can be added” to a clinician’s toolbox, Dr. Feder said.
 

Speaks to clinical utility

Commenting for this news organization, Gerard Sanacora, MD, PhD, professor of psychiatry at Yale University, New Haven, Connecticut, called this a “very solid and well-designed” study.

“It definitely builds on what’s been found in the past, but it’s a critical piece of information speaking to the clinical utility of this treatment for PTSD,” said Dr. Sanacora, who is also director of the Yale Depression Research Program and was not involved with the current research.

He agreed with the investigators that PTSD has long been a condition that is difficult to treat.

“It’s an area that has a great unmet need for treatment options. Beyond that, as ketamine is becoming more widely used, there’s increasing demand for off-label uses. This [study] actually provides some evidence that there may be efficacy there,” Dr. Sanacora said.

Although he cautioned that this was a small study, and thus further research with a larger patient population will be needed, it provides a compelling foundation to build upon.

“This study provides clear evidence to support a larger study to really give a definitive statement on the efficacy and safety of its use for PTSD. I don’t think this is the study that provides that definitive evidence, but it is a very strong indication, and it very strongly supports the initiation of a large study to address that,” said Dr. Sanacora.

He noted that, although he’s used the term “cautious optimism” for studies in the past, he has “real optimism” that ketamine will be effective for PTSD based on the results of this current study.

“We still need some more data to really convince us of that before we can say with any clear statement that it is effective and safe, but I’m very optimistic,” Dr. Sanacora concluded. “I think the data are very strong.”

The study was funded by the Brain and Behavior Research Foundation, Mount Sinai Innovation Partners and the Mount Sinai i3 Accelerator, Gerald and Glenda Greenwald, and the Ehrenkranz Laboratory for Human Resilience. Dr. Feder is a coinventor on issued patents for the use of ketamine as therapy for PTSD.

Multifocal microvascular injury in the brain and olfactory bulbs is another possible adverse outcome from COVID-19, new research suggests.

Postmortem MRI brain scans of 13 patients who died from COVID-19 showed abnormalities in 10 of the participants. Of these, nine showed punctate hyperintensities, “which represented areas of microvascular injury and fibrinogen leakage,” the investigators reported. Immunostaining also showed a thinning of the basal lamina in five of these patients.

Further analyses showed punctate hypointensities linked to congested blood vessels in 10 patients. These areas were “interpreted as microhemorrhages,” the researchers noted.

There was no evidence of viral infection, including SARS-CoV-2.

“These findings may inform the interpretation of changes observed on [MRI] of punctate hyperintensities and linear hypointensities in patients with COVID-19,” wrote Myoung-Hwa Lee, PhD, a research fellow at the National Institute of Neurological Disorders and Stroke, and colleagues. The findings were published online Dec. 30 in a “correspondence” piece in the New England Journal of Medicine.
 

Interpret with caution

The investigators examined brains from a convenience sample of 19 patients (mean age, 50 years), all of whom died from COVID-19 between March and July 2020.

An 11.7-tesla scanner was used to obtain magnetic resonance microscopy images for 13 of the patients. In order to scan the olfactory bulb, the scanner was set at a resolution of 25 mcm; for the brain, it was set at 100 mcm.

Chromogenic immunostaining was used to assess brain abnormalities found in 10 of the patients. Multiplex fluorescence imaging was also used for some of the patients.

For 18 study participants, a histopathological brain examination was performed. In the patients who also had medical histories available to the researchers, five had mild respiratory syndrome, four had acute respiratory distress syndrome, two had pulmonary embolism, one had delirium, and three had unknown symptoms.

The punctate hyperintensities found on magnetic resonance microscopy were also found on histopathological exam. Collagen IV immunostaining showed a thinning in the basal lamina of endothelial cells in these areas.

In addition to congested blood vessels, punctate hypointensities were linked to areas of fibrinogen leakage – but also to “relatively intact vasculature,” the investigators reported.

“There was minimal perivascular inflammation in the specimens examined, but there was no vascular occlusion,” they added.

SARS-CoV-2 was also not found in any of the participants. “It is possible that the virus was cleared by the time of death or that viral copy numbers were below the level of detection by our assays,” the researchers noted.

In 13 of the patients, hypertrophic astrocytes, macrophage infiltrates, and perivascular-activated microglia were found. Eight patients showed CD3+ and CD8+ T cells in spaces and lumens next to endothelial cells.

Finally, five patients showed activated microglia next to neurons. This is “suggestive of neuronophagia in the olfactory bulb, substantial nigra, dorsal motor nucleus of the vagal nerve, and the pre-Bötzinger complex in the medulla, which is involved in the generation of spontaneous rhythmic breathing,” wrote the investigators.

In summary, vascular pathology was found in 10 cases, perivascular infiltrates were present in 13 cases, acute ischemic hypoxic neurons were present in 6 cases, and changes suggestive of neuronophagia were present in 5 cases.

The researchers noted that, although the study findings may be helpful when interpreting brain changes on MRI scan in this patient population, availability of clinical information for the participants was limited.

Therefore, “no conclusions can be drawn in relation to neurologic features of COVID-19,” they wrote.

The study was funded by NINDS. Dr. Lee and all but one of the other investigators reported no relevant financial relationships; the remaining investigator reported having received grants from NINDS during the conduct of this study.

Multifocal microvascular injury in the brain and olfactory bulbs is another possible adverse outcome from COVID-19, new research suggests.

Postmortem MRI brain scans of 13 patients who died from COVID-19 showed abnormalities in 10 of the participants. Of these, nine showed punctate hyperintensities, “which represented areas of microvascular injury and fibrinogen leakage,” the investigators reported. Immunostaining also showed a thinning of the basal lamina in five of these patients.

Further analyses showed punctate hypointensities linked to congested blood vessels in 10 patients. These areas were “interpreted as microhemorrhages,” the researchers noted.

There was no evidence of viral infection, including SARS-CoV-2.

“These findings may inform the interpretation of changes observed on [MRI] of punctate hyperintensities and linear hypointensities in patients with COVID-19,” wrote Myoung-Hwa Lee, PhD, a research fellow at the National Institute of Neurological Disorders and Stroke, and colleagues. The findings were published online Dec. 30 in a “correspondence” piece in the New England Journal of Medicine.

The investigators examined brains from a convenience sample of 19 patients (mean age, 50 years), all of whom died from COVID-19 between March and July 2020.

An 11.7-tesla scanner was used to obtain magnetic resonance microscopy images for 13 of the patients. In order to scan the olfactory bulb, the scanner was set at a resolution of 25 mcm; for the brain, it was set at 100 mcm.

Chromogenic immunostaining was used to assess brain abnormalities found in 10 of the patients. Multiplex fluorescence imaging was also used for some of the patients.

For 18 study participants, a histopathological brain examination was performed. In the patients who also had medical histories available to the researchers, five had mild respiratory syndrome, four had acute respiratory distress syndrome, two had pulmonary embolism, one had delirium, and three had unknown symptoms.

The punctate hyperintensities found on magnetic resonance microscopy were also found on histopathological exam. Collagen IV immunostaining showed a thinning in the basal lamina of endothelial cells in these areas.

In addition to congested blood vessels, punctate hypointensities were linked to areas of fibrinogen leakage – but also to “relatively intact vasculature,” the investigators reported.

“There was minimal perivascular inflammation in the specimens examined, but there was no vascular occlusion,” they added.

SARS-CoV-2 was also not found in any of the participants. “It is possible that the virus was cleared by the time of death or that viral copy numbers were below the level of detection by our assays,” the researchers noted.
