An intensive lifestyle intervention significantly improved cognition and function in many patients with mild cognitive impairment (MCI) or early dementia due to Alzheimer’s disease, in what authors said is the first randomized controlled trial of intensive lifestyle modification for patients diagnosed with Alzheimer’s disease. Results could help physicians address patients at risk of Alzheimer’s disease who reject relevant testing because they believe nothing can forestall development of the disease, the authors added. The study was published online in Alzheimer’s Research & Therapy.

Although technology allows probable Alzheimer’s disease diagnosis years before clinical symptoms appear, wrote investigators led by Dean Ornish, MD, of the Preventive Medicine Research Institute in Sausalito, California, “many people do not want to know if they are likely to get Alzheimer’s disease if they do not believe they can do anything about it. If intensive lifestyle changes may cause improvement in cognition and function in MCI or early dementia due to Alzheimer’s disease, then it is reasonable to think that these lifestyle changes may also help to prevent MCI or early dementia due to Alzheimer’s disease.” As with cardiovascular disease, the authors added, preventing Alzheimer’s disease might require less intensive lifestyle modifications than treating it.
 

Study Methodology

Investigators randomized 26 patients with Montréal Cognitive Assessment scores of 18 or higher to an intensive intervention involving nutrition, exercise, and stress management techniques. To improve adherence, the protocol included participants’ spouses or caregivers.

Two patients, both in the treatment group, withdrew over logistical concerns.

After 20 weeks, treated patients exhibited statistically significant differences in several key measures versus a 25-patient usual-care control group. Scores that improved in the intervention group and worsened among controls included the following:

• Clinical Global Impression of Change (CGIC, P = .001)
• Clinical Dementia Rating-Global (CDR-Global, -0.04, P = .037)
• Clinical Dementia Rating Sum of Boxes (CDR-SB, +0.08, P = .032)
• Alzheimer’s Disease Assessment Scale (ADAS-Cog, -1.01, P = .053)

The validity of these changes in cognition and function, and possible biological mechanisms of improvement, were supported by statistically significant improvements in several clinically relevant biomarkers versus controls, the investigators wrote. These biomarkers included Abeta42/40 ratio, HbA1c, insulin, and glycoprotein acetylation. “This information may also help in predicting which patients are more likely to show improvements in cognition and function by making these intensive lifestyle changes,” the authors added.

In primary analysis, the degree of lifestyle changes required to stop progression of MCI ranged from 71.4% (ADAS-Cog) to 120.6% (CDR-SB). “This helps to explain why other studies of less intensive lifestyle interventions may not have been sufficient to stop deterioration or improve cognition and function,” the authors wrote. Moreover, they added, variable adherence might explain why in the intervention group, 10 patients improved their CGIC scores, while the rest held static or worsened.
 

Caveats

Alzheimer’s Association Vice President of Medical and Scientific Relations Heather M. Snyder, PhD, said, “This is an interesting paper in an important area of research and adds to the growing body of literature on how behavior or lifestyle may be related to cognitive decline. However, because this is a small phase 2 study, it is important for this or similar work to be done in larger, more diverse populations and over a longer duration of the intervention.” She was not involved with the study but was asked to comment.

Investigators chose the 20-week duration, they explained, because control-group patients likely would not refrain from trying the lifestyle intervention beyond that timeframe. Perhaps more importantly, challenges created by the COVID-19 pandemic required researchers to cut planned enrollment in half, eliminate planned MRI and amyloid PET scans, and reduce the number of cognition and function tests.

Such shortcomings limit what neurologists can glean and generalize from the study, said Dr. Snyder. “That said,” she added, “it does demonstrate the potential of an intensive behavior/lifestyle intervention, and the importance of this sort of research in Alzheimer’s and dementia.” Although the complexity of the interventions makes these studies challenging, she added, “it is important that we continue to advance larger, longer studies in more representative study populations to develop specific recommendations.”
 

Further Study

The Alzheimer’s Association’s U.S. POINTER study is the first large-scale study in the United States to explore the impact of comprehensive lifestyle changes on cognitive health. About 2000 older adults at risk for cognitive decline are participating, from diverse locations across the country. More than 25% of participants come from groups typically underrepresented in dementia research, said Dr. Snyder. Initial results are expected in summer 2025.

Future research also should explore reasons (beyond adherence) why some patients respond to lifestyle interventions better than others, and the potential synergy of lifestyle changes with drug therapies, wrote Dr. Ornish and colleagues.

“For now,” said Dr. Snyder, “there is an opportunity for providers to incorporate or expand messaging with their patients and families about the habits that they can incorporate into their daily lives. The Alzheimer’s Association offers 10 Healthy Habits for Your Brain — everyday actions that can make a difference for your brain health.”

Investigators received study funding from more than two dozen charitable foundations and other organizations. Dr. Snyder is a full-time employee of the Alzheimer’s Association and in this role, serves on the leadership team of the U.S. POINTER study. Her partner works for Abbott in an unrelated field.

Among stroke survivors with diabetes or obesity, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) reduced secondary stroke risk by up to 16%, according to authors of a recent meta-analysis. With benefits across administration routes, dosing regimens, type 2 diabetes status, and total and nonfatal strokes, the findings could improve GLP-1 RA implementation by stroke specialists in patients with stroke history and concurrent type 2 diabetes or obesity, authors said. The study was published online in the International Journal of Stoke.

Extending Longevity

Agents including GLP-1 RAs that have been found to reduce cardiovascular events among patients with type 2 diabetes and patients who are overweight or obese also reduce risk of recurrent stroke among patients with a history of stroke who are overweight, obese, or have metabolic disease, said American Heart Association (AHA) Chief Clinical Science Officer Mitchell S. V. Elkind, MD, who was not involved with the study but was asked to comment.

“Stroke is a leading cause of mortality and the leading cause of serious long-term disability,” he added, “so medications that help to reduce that risk can play an important role in improving overall health and well-being and hopefully reducing premature mortality.”

Investigators Anastasia Adamou, MD, an internal medicine resident at AHEPA University Hospital in Thessaloniki, Greece, and colleagues searched MEDLINE and Scopus for cardiovascular outcome trials involving adults randomly assigned to GLP-1 RAs or placebo through November 2023, ultimately analyzing 11 randomized controlled trials (RCTs).

Among 60,380 participants in the nine studies that assessed total strokes, 2.5% of the GLP-1 RA group experienced strokes during follow-up, versus 3% in the placebo group (relative risk [RR] 0.85, 95% confidence interval [CI] 0.77-0.93). Regarding secondary outcomes, the GLP-1 RA group showed a significantly lower rate of nonfatal strokes versus patients on placebo (RR 0.87, 95% CI 0.79-0.95). Conversely, investigators observed no significant risk difference among the groups regarding fatal strokes, probably due to the low rate of events — 0.3% and 0.4% for treated and untreated patients, respectively.

Subgroup analyses revealed no interaction between dosing frequency and total, nonfatal, or fatal strokes. The investigators observed no difference in nonfatal strokes among participants by type 2 diabetes status and medication administration route (oral versus subcutaneous).

“The oral administration route could provide the advantage of lower local ecchymoses and allergic reactions due to subcutaneous infusions,” Dr. Adamou said in an interview. But because oral administration demands daily intake, she added, treatment adherence might be affected. “For this reason, our team performed another subgroup analysis to compare the once-a-day to the once-a-month administration. No interaction effect was again presented between the two subgroups. This outcome allows for personalization of the administration method for each patient.”

Addressing Underutilization

Despite more than 2 decades of widespread use and well-established effects on body weight, HbA1c, and cardiovascular risk, GLP-1 RAs remain underutilized, authors wrote. This is especially true in primary care, noted one study published in Clinical Diabetes.

“GLP-1 RAs have been used for many years to treat diabetic patients,” said Dr. Adamou. But because their impact on cardiovascular health regardless of diabetic status is only recently known, she said, physicians are exercising caution when prescribing this medication to patients without diabetes. “This is why more studies need to be available, especially RCTs.”

Most neurologists traditionally have left management of type 2 diabetes and other metabolic disorders to primary care doctors, said Dr. Elkind. “However, these medications are increasingly important to vascular risk reduction and should be considered part of the stroke specialist’s armamentarium.”

Vascular neurologists can play an important role in managing metabolic disease and obesity by recommending GLP-1 RAs for patients with a history of stroke, or by initiating these medications themselves, Dr. Elkind said. “These drugs are likely to become an important part of stroke patients’ medication regimens, along with antithrombotic agents, blood pressure control, and statins. Neurologists are well-positioned to educate other physicians about the important connections among brain, heart, and metabolic health.”

To that end, he said, the AHA will update guidelines for both primary and secondary stroke prevention as warranted by evidence supporting GLP-1 RAs and other medications that could impact stroke risk in type 2 diabetes and related metabolic disorders. However, no guidelines concerning use of GLP-1 RAs for secondary stroke prevention in obesity exist. Here, said Dr. Elkind, the AHA will continue building on its innovative Cardiovascular-Kidney Metabolic Health program, which includes clinical suggestions and may include more formal clinical practice guidelines as the evidence evolves.

Among the main drivers of the initiative, he said, is the recognition that cardiovascular disease — including stroke — is the major cause of death and morbidity among patients with obesity, type 2 diabetes, and metabolic disorders. “Stroke should be considered an important part of overall cardiovascular risk, and the findings that these drugs can help to reduce the risk of stroke specifically is an important additional reason for their use.”

Dr. Elkind and Dr. Adamou reported no conflicting interests. The authors received no financial support for the study.

As the availability of potential biomarkers for Parkinson’s disease drives the debate around diagnosing prodromal Parkinson’s disease (pPD) from theory to practice, said authors of a recent study, clinicians should weigh each patient’s preferences, circumstances, and goals against the potential benefits and harms of disclosure. The study and an accompanying editorial appeared online in Neurology.

Because markers such as SNCA, LRRK2, and GBA mutations impact small subgroups of patients at risk of developing monogenic forms of Parkinson’s disease, wrote Richard N. Rees, MBChB, MD, from the Department of Clinical and Movement Neurosciences at University College London Queen Square Institute of Neurology, and colleagues, researchers are working to identify people at risk of idiopathic Parkinson’s disease using models based on known risk and protective factors. The recent development of highly accurate cerebrospinal fluid (and potentially serum) alpha-synuclein seed amplification assays, which may show Parkinson’s disease’s signature before overt symptoms appear, will reinforce these efforts, authors added.
 

‘Tap the Brakes’

However, sources interviewed by Neurology Reviews counseled caution with potential prodromal Parkinson’s disease biomarkers. “As the science advances in Parkinson’s disease and related disorders,” said Michael S. Okun, MD, “our ability to predict who will and will not be diagnosed will improve. We should, however, tap the brakes and consider the consequences of making a diagnosis in someone at risk — especially someone without symptoms.” Dr. Okun is National Medical Advisor to the Parkinson’s Foundation and director of the Norman Fixel Institute for Neurological Diseases at University of Florida Health in Gainesville, Florida. He was not involved with the study.

Neurologists should ask themselves why they are testing for Parkinson’s disease biomarkers, said Dr. Okun, and what counseling and shared decision-making they provided beforehand. “This already complex scenario becomes even more complicated when we consider that many people with GBA gene mutations and some with LRRK2 mutations may never actually manifest Parkinson’s disease.”

A Holistic Approach to Shared Decision-Making

To avoid needlessly scaring patients, Dr. Hoy suggested broaching the topic of Parkinson’s disease biomarkers during advance care planning. “In the same conversation that you might talk about establishing surrogate decision-makers or potential do-not-resuscitate/intubate orders, you can talk about the potential of predictive testing, which is becoming more prevalent across domains of clinical practice.”

Understanding each patient’s values, preferences, and priorities requires a holistic approach, he said. “In the context of prodromal Parkinson’s disease, the benefits of enrolling in a new clinical trial or implementing lifestyle changes might vary depending on the person. Do you think this person would be likely to enroll in a clinical trial or implement those lifestyle changes?” Additionally, he recommended considering how a patient might react to a false diagnosis.

Whereas a diagnosis of mild cognitive impairment might not lead to Alzheimer’s disease or dementia, wrote Dr. Rees and colleagues, growing evidence including a review published in Neurology in 2022 supports the accuracy of alpha-synuclein seed amplification assays in detecting both established and prodromal Parkinson’s disease. For people thusly diagnosed, Dr. Rees and colleagues wrote, the psychosocial burden of inevitable progression could create feelings of helplessness, possibly undermining benefits of early knowledge.

Beyond patients’ reactions, said Dr. Hoy, a diagnosis of prodromal Parkinson’s disease could result in social stigma, changes to interpersonal relationships, or discrimination. “Understanding the implications and uncertainties of potential disclosure, relative to what a person would want to know or might be able to do about it, will be the key for deciding when is the right time,” he said.
 

Supporting Primary Care

As the shared decision-making burden likely will fall to primary care providers, Dr. Hoy added, neurologists should prioritize increasing these providers’ capacity to advise and refer patients appropriately. Although it is too soon to develop clinical guidelines, he said, neurologists could help educate such providers about pPD and the growing availability of promising biomarkers.

“Parkinson’s is thought of as a movement disorder first and foremost,” said Dr. Hoy. However, various non-motor symptoms including sleep problems, depression, anxiety, apathy, constipation, and gastrointestinal issues often appear before movement-related symptoms during the prodromal phase.

As potentially the first line of defense against prodromal Parkinson’s disease, primary care providers also should know the distinction between early and timely diagnosis, added Dr. Hoy. Introduced by Dr. Rees and colleagues in a 2018 review published in F1000Research, timely diagnosis balances patient preferences, the availability and efficacy of DMT, and health systems’ ability to support and manage individuals at every stage of disease.

The current study was funded by a Parkinson’s UK grant (which paid Dr. Rees’s salary). The editorial was supported by a National Institute of Mental Health Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative award, a grant from the National Institute on Aging, and a Wellcome Discovery Award. Dr. Hoy reported no relevant disclosures.

As the availability of potential biomarkers for Parkinson’s disease drives the debate around diagnosing prodromal Parkinson’s disease (pPD) from theory to practice, said authors of a recent study, clinicians should weigh each patient’s preferences, circumstances, and goals against the potential benefits and harms of disclosure. The study and an accompanying editorial appeared online in Neurology.

Because markers such as SNCA, LRRK2, and GBA mutations impact small subgroups of patients at risk of developing monogenic forms of Parkinson’s disease, wrote Richard N. Rees, MBChB, MD, from the Department of Clinical and Movement Neurosciences at University College London Queen Square Institute of Neurology, and colleagues, researchers are working to identify people at risk of idiopathic Parkinson’s disease using models based on known risk and protective factors. The recent development of highly accurate cerebrospinal fluid (and potentially serum) alpha-synuclein seed amplification assays, which may show Parkinson’s disease’s signature before overt symptoms appear, will reinforce these efforts, authors added.
 

‘Tap the Brakes’

However, sources interviewed by Neurology Reviews counseled caution with potential prodromal Parkinson’s disease biomarkers. “As the science advances in Parkinson’s disease and related disorders,” said Michael S. Okun, MD, “our ability to predict who will and will not be diagnosed will improve. We should, however, tap the brakes and consider the consequences of making a diagnosis in someone at risk — especially someone without symptoms.” Dr. Okun is National Medical Advisor to the Parkinson’s Foundation and director of the Norman Fixel Institute for Neurological Diseases at University of Florida Health in Gainesville, Florida. He was not involved with the study.

Neurologists should ask themselves why they are testing for Parkinson’s disease biomarkers, said Dr. Okun, and what counseling and shared decision-making they provided beforehand. “This already complex scenario becomes even more complicated when we consider that many people with GBA gene mutations and some with LRRK2 mutations may never actually manifest Parkinson’s disease.”

The most reliable predictors of remission in newly diagnosed epilepsy include patient history, seizure characteristics, and onset age, according to authors of a recent review. Clinical prediction models can help neurologists identify which patients could benefit from more aggressive early treatment, authors added, although concerns over bias and model applicability leave room for improvement.

Triggering Aggressive Treatments

“These models are helpful because if you can predict that someone is going to do well with one or two medications, that’s great,” said Aatif M. Husain, MD. “But if you know early on that someone likely will not do well, will need many medications, and still not have their seizures under control, you’re much more likely to be more aggressive with their management, such as closely refer them to a specialist epilepsy center and evaluate them for surgical treatment options. This could minimize the amount of time their seizures are inadequately controlled.” Dr. Husain is an epileptologist, neurologist, and sleep medicine specialist at Duke University Health System in Durham, North Carolina. Dr. Husain was not involved with the study, which was published in Epilepsia.

“But the other important finding is that these models so far have not been that great,” he added.

Prognosis Predictors

Investigators Corey Ratcliffe of the University of Liverpool in England and colleagues systematically searched MEDLINE and Embase for relevant publications, ultimately analyzing 48 models across 32 studies. The strongest predictors of seizure remission were history and seizure types or characteristics, the authors wrote, followed by onset age.

Regarding seizure history, a March 2018 JAMA Neurology study and a December 2013 BMC Neurology study linked factors such as history of seizures in the year pre-diagnosis, family history of epilepsy, and history of febrile seizures and of migraines with lower chances of seizure remission. Seizure types with increased chances of poor outcomes in the review included status epilepticus and seizures with complex or mixed etiologies. Additional seizure types associated with poor control include tonic-clonic seizures, frequent focal seizures, and seizures stemming from certain genetic predispositions, said Dr. Husain.

Although the roles of many of the foregoing factors are easily explained, he added, other variables’ impact is less clear. Younger onset often signals more refractory seizures, for example, while data regarding older onset are mixed. “Sometimes older individuals will have mild epilepsy due to a stroke, tumor, or something that can be relatively easily treated,” said Dr. Husain. Conversely, epilepsy can become more complicated if such patients take several medications and/or have coexisting medical problems that seizures or antiseizure medications exacerbate. “So sometimes it’s not so obvious.”
 

Incorporating Imaging, AI

Dr. Husain found it surprising that very few of the selected models incorporated EEG and MRI findings. “Subsequent research should look at those, since they are important diagnostic tests.” Moreover, he recommended including more sophisticated quantitative and connectivity analyses of EEG and MRI data. These analyses might provide additional prognostic information beyond a simple visual analysis of these tests, Dr. Husain explained, although their potential here remains unproven.

As for factors not represented in the review, he said, future studies will help clarify AI’s role in predicting newly diagnosed epilepsy outcomes. A study published in Epilepsia showed that among 248 potential pediatric surgical candidates, those whose providers received alerts based on machine learning analysis of prior visit notes were more likely to be referred for presurgical evaluation (9.8% versus 3.1%). Future clinical models will use AI to examine not only established elements of neurologic history, said Dr. Husain, but also other types of history such as socioeconomic characteristics, geographic location, and other such data.

Additionally, study authors recommended a standardized approach to prediction modeling, using Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) guidelines. Using consistent definitions, outcomes, and reporting requirements will facilitate communication among researchers, reduce bias, and support systematic between-study comparisons, Mr. Ratcliffe and colleagues wrote.
 

Reaching General Neurologists

Epilepsy specialists are generally aware of reliable outcome predictors, Dr. Husain said, though they do not use models per se. “But the vast majority of patients with epilepsy are seen by general neurologists.” And the lack of awareness among these physicians and primary care practitioners drives a need for education to facilitate appropriate referrals to subspecialty centers, he said.

The stakes for timely referrals can be high. Although using appropriate outcome models improves patients’ quality of life sooner, said Dr. Husain, allowing seizures to go untreated or undertreated results in neuroplastic changes that hinder long-term seizure control.

The fact that all 32 included studies reflected a high risk of bias, and 9 studies raised high applicability concerns, raises questions regarding the models’ validity, he added. Mr. Ratcliffe and colleagues attributed both types of concerns to the fact that 20% of included studies used baseline treatment response data as outcome predictors.

Nevertheless, Dr. Husain cautioned against dismissing prediction models in newly diagnosed epilepsy. “Practicing neurologists need to realize that the perfect model has yet to be developed. But the current tools can be used to help manage patients with epilepsy and predict who will do well and not as well,” he said.

Dr. Husain is a member of the American Epilepsy Society. He has been a consultant and researcher for Marinus Pharmaceuticals, PranaQ, and UCB, and a consultant for Eisai, Jazz Pharmaceuticals, Merck, and uniQure. Study authors reported no funding sources or relevant conflicts of interest.

In a small, nonrandomized controlled trial, the injectable calcitonin gene-related peptide (CGRP) inhibitor erenumab significantly reduced treatment-resistant flushing and erythema associated with rosacea. Skin-related quality-of-life (QOL) measures also improved, albeit modestly.

The study was published in JAMA Dermatology.

“The transient erythema of rosacea is one of the most challenging rosacea symptoms to treat,” Emmy Graber, MD, MBA, who was not involved with the study, said in an interview. “As flushing can adversely impact quality of life in our rosacea patients, it is important to find therapeutic options for our patients. This study is exciting, not only because the treatment was successful for a notable number of patients, but also because it involved a drug with a novel mode of action in rosacea.” Dr. Graber practices in Boston and is an affiliate clinical instructor at Northeastern University, Boston.

Spotlight on CGRP

Rosacea’s pathophysiology remains incompletely understood, wrote Nita K.F. Wienholtz, MD, PhD, Department of Dermatology, Bispebjerg and Frederiksberg Hospital, University of Copenhagen, Denmark, and coinvestigators. However, they added, mounting evidence suggests a possible role for CGRP. For example, a study published in JAMA Dermatology in 2015 revealed elevated CGRP levels in facial skin biopsies from patients with rosacea.

For the present study, the investigators enrolled 30 adults (including 23 women) with rosacea who experienced at least 15 days of moderate to severe erythema or extreme flushing during a 4-week, treatment-free run-in period. Most participants (87%) had previously failed one or more rosacea treatments because of a lack of efficacy or adverse reactions, and 43% had failed three or more treatments.

Participants received 3-monthly 140-mg doses of erenumab, which is approved by the Food and Drug Administration for migraine prevention. Patients recorded scores on the Patient Self-Assessment (PSA) and item 2 of the Flushing Assessment Tool online daily and made a final follow-up visit 12 weeks after the third dose.

Among the 27 patients who completed the study, the mean number of days with moderate to severe flushing from week 9 to week 12 fell by 6.9 from 23.6 days over 4 weeks at baseline (P < .001). Patients most severely affected by flushing at baseline experienced an 81% decline in days with severe to extreme flushing. Overall, 26% of patients experienced at least 50% reductions in moderate to extreme flushing days. The number of days with moderate to severe erythema as measured by PSA fell by 8.1 (mean) from baseline, and 56% of patients experienced at least 50% reductions in PSA scores. No unexpected safety signals emerged.
 

Questions Over QOL Data

“Although there were significant decreases in flushing and erythema,” wrote John S. Barbieri, MD, MBA, in an accompanying Editor’s Note, “the present study had relatively modest improvements in quality of life.” He is director of the Advanced Acne Therapeutics Clinic, Brigham and Women’s Hospital, Boston, and associate editor and evidence-based practice editor of JAMA Dermatology.

Barbieri_John2024_Boston_web.jpg

Compared with baseline (6.22), mean Dermatology Life Quality Index scores fell 2.08 points and 2.73 points at weeks 8 and 20, respectively (P = .004 and .003). At the same intervals, the mean baseline Rosacea Quality of Life score (48.22) decreased by 2.58 points and 4.14 points, respectively (P = .04 and .02).

No significant changes appeared in gauges of anxiety and depression. These findings, authors wrote, could stem from their decision to omit a follow-up visit at week 12 — where they may have seen mental-health effects which disappeared by week 20 — in response to patients’ logistical concerns.

However, Dr. Webster questioned the value of QOL measurements in rosacea. “Quality-of-life measures are blunt instruments,” he explained, and reducing severe itching or chronic pain improves the lives of affected patients. “But what question are you going to ask to tease out whether being less red-cheeked has made someone’s life easier? It’s not a problem that lends itself to quality-of-life assessments.” Moreover, he said, regulators who increasingly require such measures in clinical trials ignore this point, creating challenges for drug developers and researchers.

Because the study was neither blinded nor controlled, Dr. Webster suggested considering it a tantalizing proof of concept. “If I were putting money into a CGRP inhibitor, I’d want at least a small, placebo-controlled, double-blinded study.”

Study authors and Dr. Barbieri recommended larger randomized studies involving different populations and erenumab doses. For now, Dr. Barbieri wrote, CGRP inhibition represents a promising potential strategy for patients who have rosacea with comorbid migraine or recalcitrant flushing and erythema.

In a small, nonrandomized controlled trial, the injectable calcitonin gene-related peptide (CGRP) inhibitor erenumab significantly reduced treatment-resistant flushing and erythema associated with rosacea. Skin-related quality-of-life (QOL) measures also improved, albeit modestly.

The study was published in JAMA Dermatology.

“The transient erythema of rosacea is one of the most challenging rosacea symptoms to treat,” Emmy Graber, MD, MBA, who was not involved with the study, said in an interview. “As flushing can adversely impact quality of life in our rosacea patients, it is important to find therapeutic options for our patients. This study is exciting, not only because the treatment was successful for a notable number of patients, but also because it involved a drug with a novel mode of action in rosacea.” Dr. Graber practices in Boston and is an affiliate clinical instructor at Northeastern University, Boston.

Spotlight on CGRP

Rosacea’s pathophysiology remains incompletely understood, wrote Nita K.F. Wienholtz, MD, PhD, Department of Dermatology, Bispebjerg and Frederiksberg Hospital, University of Copenhagen, Denmark, and coinvestigators. However, they added, mounting evidence suggests a possible role for CGRP. For example, a study published in JAMA Dermatology in 2015 revealed elevated CGRP levels in facial skin biopsies from patients with rosacea.

For the present study, the investigators enrolled 30 adults (including 23 women) with rosacea who experienced at least 15 days of moderate to severe erythema or extreme flushing during a 4-week, treatment-free run-in period. Most participants (87%) had previously failed one or more rosacea treatments because of a lack of efficacy or adverse reactions, and 43% had failed three or more treatments.

Participants received 3-monthly 140-mg doses of erenumab, which is approved by the Food and Drug Administration for migraine prevention. Patients recorded scores on the Patient Self-Assessment (PSA) and item 2 of the Flushing Assessment Tool online daily and made a final follow-up visit 12 weeks after the third dose.

Among the 27 patients who completed the study, the mean number of days with moderate to severe flushing from week 9 to week 12 fell by 6.9 from 23.6 days over 4 weeks at baseline (P < .001). Patients most severely affected by flushing at baseline experienced an 81% decline in days with severe to extreme flushing. Overall, 26% of patients experienced at least 50% reductions in moderate to extreme flushing days. The number of days with moderate to severe erythema as measured by PSA fell by 8.1 (mean) from baseline, and 56% of patients experienced at least 50% reductions in PSA scores. No unexpected safety signals emerged.
 

Questions Over QOL Data

“Although there were significant decreases in flushing and erythema,” wrote John S. Barbieri, MD, MBA, in an accompanying Editor’s Note, “the present study had relatively modest improvements in quality of life.” He is director of the Advanced Acne Therapeutics Clinic, Brigham and Women’s Hospital, Boston, and associate editor and evidence-based practice editor of JAMA Dermatology.

Compared with baseline (6.22), mean Dermatology Life Quality Index scores fell 2.08 points and 2.73 points at weeks 8 and 20, respectively (P = .004 and .003). At the same intervals, the mean baseline Rosacea Quality of Life score (48.22) decreased by 2.58 points and 4.14 points, respectively (P = .04 and .02).

No significant changes appeared in gauges of anxiety and depression. These findings, authors wrote, could stem from their decision to omit a follow-up visit at week 12 — where they may have seen mental-health effects which disappeared by week 20 — in response to patients’ logistical concerns.

However, Dr. Webster questioned the value of QOL measurements in rosacea. “Quality-of-life measures are blunt instruments,” he explained, and reducing severe itching or chronic pain improves the lives of affected patients. “But what question are you going to ask to tease out whether being less red-cheeked has made someone’s life easier? It’s not a problem that lends itself to quality-of-life assessments.” Moreover, he said, regulators who increasingly require such measures in clinical trials ignore this point, creating challenges for drug developers and researchers.

Because the study was neither blinded nor controlled, Dr. Webster suggested considering it a tantalizing proof of concept. “If I were putting money into a CGRP inhibitor, I’d want at least a small, placebo-controlled, double-blinded study.”

Study authors and Dr. Barbieri recommended larger randomized studies involving different populations and erenumab doses. For now, Dr. Barbieri wrote, CGRP inhibition represents a promising potential strategy for patients who have rosacea with comorbid migraine or recalcitrant flushing and erythema.

Dermatologists are well aware of guidelines limiting long-term antibiotic use for acne to 3-4 months, but a perceived lack of supporting data, along with in-office realities unaddressed by guidelines, hinder clinicians’ ability and willingness to follow them, according to the authors of a recently published study.

“This study explored why dermatologists still prescribe a good number of long-term antibiotics for people with acne,” the study’s senior author Howa Yeung, MD, MSc, assistant professor of dermatology at Emory University, Atlanta, said in an interview. “And we found a lot of reasons.” The study was published online in JAMA Dermatology.

Yeung_Howa_ATLANTA_2022_web.jpg

Using online surveys and semi-structured video interviews of 30 dermatologists, infectious disease physicians with expertise in antimicrobial stewardship, dermatology residents, and nonphysician clinicians, the investigators assessed respondents’ knowledge and attitudes regarding long-term antibiotics in acne. Salient themes impacting long-term antibiotic prescriptions included the following:

• A perceived dearth of evidence to justify changes in practice.
• Difficulties with iPLEDGE, the Risk Evaluation and Mitigation Strategy (REMS) for managing the teratogenic risks associated with isotretinoin, and with discussing oral contraceptives.
• “Navigating” discussions with about tapering-off of antibiotics.
• Challenging patient demands.
• A lack of effective tools for monitoring progress in antibiotic stewardship.

“It’s surprising there are so many barriers that make it difficult for dermatologists to stick with the guidelines even if they want to,” said Dr. Yeung, a coauthor of the recently released updated American Academy of Dermatology (AAD) acne management guidelines.

A dermatologist who wants to stop systemic antibiotics within 3 months may not know how to do so, he explained, or high demand for appointments may prevent timely follow-ups.

A major reason why dermatologists struggle to limit long-term antibiotic use is that there are very few substitutes that are perceived to work as well, said David J. Margolis, MD, PhD, who was not involved with the study and was asked to comment on the results. He is professor of epidemiology and dermatology at the University of Pennsylvania, Philadelphia.

“Part of the reason antibiotics are being used to treat acne is that they’re effective, and effective for severe disease,” he said. The alternatives, which are mostly topicals, said Dr. Margolis, do not work as well for moderate to severe disease or, with isotretinoin, involve time-consuming hurdles. Dr. Margolis said that he often hears such concerns from individual dermatologists. “But it’s helpful to see these in a well-organized, well-reported qualitative study.”

Infectious disease specialists surveyed considered limiting long-term antibiotic use as extremely important, while several dermatologists “argued that other specialties ‘underestimate the impact acne has on people’s lives,’ ” the authors wrote. Other respondents prioritized making the right choice for the patient at hand.

Although guidelines were never meant to be black and white, Dr. Yeung said, it is crucial to target the goal of tapering off after about 3-4 months — a cutoff with which guidelines from groups including the AAD, the Japanese Dermatological Association in guidelines from 2016, and 2017, respectively, and others concur.

He added, “Some folks believe that if the oral antibiotic is working, why stop? We need to develop evidence to show that reducing oral antibiotic use is important to our patients, not just to a theoretical problem of antibiotic resistance in society.” For example, in a study published in The Lancet in 2004, patients who used strictly topical regimens achieved efficacy similar to that of those who used only oral antibiotics.

[embed:render:related:node:268230]

In addition, some clinicians worried that limiting antibiotics could reduce patient satisfaction, spurring switches to other providers. However, he and the other authors of the JAMA Dermatology study noted that in a survey of patients with acne published in the Journal of Clinical and Aesthetic Dermatology in 2019, 76.9% said they would be “very or extremely likely” to use effective antibiotic-free treatments if offered.

Because most respondents were highly aware of the importance of antibiotic stewardship, Dr. Yeung said, additional passive education is not necessarily the answer. “It will take a concerted effort by our national societies to come up with resources and solutions for individual dermatologists to overcome some of these larger barriers.” Such solutions could range from training in communication and shared decision-making to implementing systems that provide individualized feedback to support antibiotic stewardship.

Many ongoing studies are examining antibiotic stewardship, Dr. Margolis said in the interview. However, he added, dermatologists’ idea of long-term use is 3 months, versus 1 month or less in other specialties. “Moreover, dermatology patients tend to be much healthier individuals and are rarely hospitalized, so there may be some issues comparing the ongoing studies to individuals with acne.” Future research will need to account for such differences, he said.

The study was funded by an American Acne & Rosacea Society Clinical Research Award. Dr. Yeung is associate editor of JAMA Dermatology. Dr. Margolis has received a National Institutes of Health grant to study doxycycline versus spironolactone in acne.

Three recent publications highlight the ability of telestroke protocols not only to match the quality of in-person care, but in some instances to exceed it. These studies set the stage for larger studies comparing outcomes and efficiency of various telemedicine and transport models and gauging stakeholder satisfaction, authors said.

Surprising Results

In a single-site retrospective comparison of 252 patients with acute stroke assessed under an in-house telestroke protocol and 2437 assessed in person, telestroke provided statistically significant advantages in the following areas:

• Door-to-imaging times (median: 38 minutes vs 44)
• Rates of intravenous (18.2% vs 8.6%) and mechanical (10.4% vs 5.1%) treatment
• Length of stay (median: 6 days vs 8)
• Symptomatic hemorrhagic transformation rate (1.1% vs 5.1%)
• Mortality (6.7% vs 11.1%)

Massaud_Rodrigo_BRAZIL_web.jpg

The better metrics observed in the telestroke group were especially surprising, said lead author Rodrigo Meirelles Massaud, MD, because the same team of neurologists conducted both types of evaluations. “This consistency ensures that the quality and expertise of medical care were maintained across both groups,” said Dr. Massaud, a neurologist at the Hospital Israelita Albert Einstein in São Paulo, Brazil. The study appeared online in Frontiers in Neurology.

The findings also counter the preconceived notion that distance medicine could be inferior because of the inability to conduct direct physical examinations and the potential for communication failures, he said. The telestroke group’s younger average age (63.5 years vs 69.5 years) and lower initial National Institutes of Health Stroke Scale (NIHSS) scores — 2 versus 3 — might explain the disparity, Dr. Massaud added, because both factors augur improved outcomes.

Conversely, the authors wrote that the in-person group’s lower median door-to-groin puncture time in ischemic stroke (103.5 minutes vs 151.5 for telemedicine) likely resulted from the need to transport patients from satellite facilities to a hub hospital with neurologists on continuous standby. After adjustment for initial NIHSS score and age, both groups achieved similar percentages of patients with modified Rankin Scale (mRS) scores of 0-2 at discharge: 58.5% for in-person evaluation versus 61.9% for telemedicine (P = .028).
 

Acute Ischemic Stroke

In another study, a systematic review that included 7396 thrombolysed patients with acute ischemic stroke, odds ratios (ORs) revealed no significant differences between telestroke and in-person care for the percentage of mRS scores 0-2 at discharge (1.06; P = .5), 90-day mortality (OR, 1.16; P = .17), and symptomatic intracranial hemorrhage (OR, 0.99; P = .93). The study appeared in the March International Journal of Stroke.

The lack of significant differences between telestroke and in-person care regarding mortality and mRS scores of 0-2 (which defines a good outcome) surprised researchers, said lead author Ahmed Mohamed, who is completing a master of health sciences degree in medical physiology at the University of Toronto Temerty Faculty of Medicine, Toronto, Ontario, Canada.

“When we were starting this project,” he said, “we thought that telemedicine would probably take longer than conventional treatment.” And waiting longer for treatment — especially for patients with acute ischemic stroke — leads to worse outcomes. “However,” Mr. Mohamed said, “that wasn’t the case.” Additional measures that showed no significant differences included rates of intravenous tissue plasminogen activator (ivtPA) use and endovascular mechanical thrombectomy.
 

Telestroke Expansion

Authors of a study that analyzed the impact of expanding telestroke coverage beyond community ERs credited many postexpansion improvements to the addition of advanced practice providers (APPs). ProMedica Stroke Network, Toledo, Ohio, added seven APPs in June 2020 to provide two-way audiovisual inpatient stroke and TIA consultations and follow-ups at 19 spoke facilities supported by vascular neurologists at the hub comprehensive stroke center (CSC).

Revamping the TS workflow resulted in a threefold increase in TS cart utilization, a 31% decrease in transfers to the CSC, and a higher home discharge rate from spoke hospitals than from the CSC (57.38% versus 52.8%, respectively). Diagnostic sensitivity also improved, with overall decreases in stroke and TIA diagnosis of 11.5% and 39.8%, respectively, and a 12.9% increase in identification of stroke mimics. The study was published in the March Annals of Neurology.
 

Future Directions

All three author groups called for larger, more granular follow-up studies. Mr. Mohamed said that the 7396-patient review of 33 studies does not show whether video consultations with neurologists produce better outcomes than phone calls, for example, or whether utilizing different telestroke modalities such as a third-party telemedicine service provides better outcomes than other methods. Additionally, authors wrote, future research should compare telestroke versus non-telestroke patient transport models to optimize treatment plans and outcomes and validate potential advantages and disadvantages of telemedicine for patients with acute ischemic stroke.

“There is also a need to understand the long-term outcomes of patients treated via telestroke versus in-person care,” said Dr. Massaud. Future studies could include randomized, controlled trials comparing telestroke to traditional care in various settings with larger sample sizes, he said. “Additionally, research into the cost-effectiveness of telestroke services, patient satisfaction, and the impact of telestroke on different subtypes of stroke could provide a more comprehensive understanding of its benefits and limitations.”

Dr. Massaud and Mr. Mohamed reported no relevant financial interests. Authors of all three studies reported no funding sources or potential conflicts of interest.

In another study, a systematic review that included 7396 thrombolysed patients with acute ischemic stroke, odds ratios (ORs) revealed no significant differences between telestroke and in-person care for the percentage of mRS scores 0-2 at discharge (1.06; P = .5), 90-day mortality (OR, 1.16; P = .17), and symptomatic intracranial hemorrhage (OR, 0.99; P = .93). The study appeared in the March International Journal of Stroke.

The lack of significant differences between telestroke and in-person care regarding mortality and mRS scores of 0-2 (which defines a good outcome) surprised researchers, said lead author Ahmed Mohamed, who is completing a master of health sciences degree in medical physiology at the University of Toronto Temerty Faculty of Medicine, Toronto, Ontario, Canada.

“When we were starting this project,” he said, “we thought that telemedicine would probably take longer than conventional treatment.” And waiting longer for treatment — especially for patients with acute ischemic stroke — leads to worse outcomes. “However,” Mr. Mohamed said, “that wasn’t the case.” Additional measures that showed no significant differences included rates of intravenous tissue plasminogen activator (ivtPA) use and endovascular mechanical thrombectomy.
 

Telestroke Expansion

Authors of a study that analyzed the impact of expanding telestroke coverage beyond community ERs credited many postexpansion improvements to the addition of advanced practice providers (APPs). ProMedica Stroke Network, Toledo, Ohio, added seven APPs in June 2020 to provide two-way audiovisual inpatient stroke and TIA consultations and follow-ups at 19 spoke facilities supported by vascular neurologists at the hub comprehensive stroke center (CSC).

Revamping the TS workflow resulted in a threefold increase in TS cart utilization, a 31% decrease in transfers to the CSC, and a higher home discharge rate from spoke hospitals than from the CSC (57.38% versus 52.8%, respectively). Diagnostic sensitivity also improved, with overall decreases in stroke and TIA diagnosis of 11.5% and 39.8%, respectively, and a 12.9% increase in identification of stroke mimics. The study was published in the March Annals of Neurology.
 

Future Directions

All three author groups called for larger, more granular follow-up studies. Mr. Mohamed said that the 7396-patient review of 33 studies does not show whether video consultations with neurologists produce better outcomes than phone calls, for example, or whether utilizing different telestroke modalities such as a third-party telemedicine service provides better outcomes than other methods. Additionally, authors wrote, future research should compare telestroke versus non-telestroke patient transport models to optimize treatment plans and outcomes and validate potential advantages and disadvantages of telemedicine for patients with acute ischemic stroke.

“There is also a need to understand the long-term outcomes of patients treated via telestroke versus in-person care,” said Dr. Massaud. Future studies could include randomized, controlled trials comparing telestroke to traditional care in various settings with larger sample sizes, he said. “Additionally, research into the cost-effectiveness of telestroke services, patient satisfaction, and the impact of telestroke on different subtypes of stroke could provide a more comprehensive understanding of its benefits and limitations.”

Dr. Massaud and Mr. Mohamed reported no relevant financial interests. Authors of all three studies reported no funding sources or potential conflicts of interest.

Three recent publications highlight the ability of telestroke protocols not only to match the quality of in-person care, but in some instances to exceed it. These studies set the stage for larger studies comparing outcomes and efficiency of various telemedicine and transport models and gauging stakeholder satisfaction, authors said.

Surprising Results

In a single-site retrospective comparison of 252 patients with acute stroke assessed under an in-house telestroke protocol and 2437 assessed in person, telestroke provided statistically significant advantages in the following areas:

• Door-to-imaging times (median: 38 minutes vs 44)
• Rates of intravenous (18.2% vs 8.6%) and mechanical (10.4% vs 5.1%) treatment
• Length of stay (median: 6 days vs 8)
• Symptomatic hemorrhagic transformation rate (1.1% vs 5.1%)
• Mortality (6.7% vs 11.1%)

Massaud_Rodrigo_BRAZIL_web.jpg

The better metrics observed in the telestroke group were especially surprising, said lead author Rodrigo Meirelles Massaud, MD, because the same team of neurologists conducted both types of evaluations. “This consistency ensures that the quality and expertise of medical care were maintained across both groups,” said Dr. Massaud, a neurologist at the Hospital Israelita Albert Einstein in São Paulo, Brazil. The study appeared online in Frontiers in Neurology.

The findings also counter the preconceived notion that distance medicine could be inferior because of the inability to conduct direct physical examinations and the potential for communication failures, he said. The telestroke group’s younger average age (63.5 years vs 69.5 years) and lower initial National Institutes of Health Stroke Scale (NIHSS) scores — 2 versus 3 — might explain the disparity, Dr. Massaud added, because both factors augur improved outcomes.

Conversely, the authors wrote that the in-person group’s lower median door-to-groin puncture time in ischemic stroke (103.5 minutes vs 151.5 for telemedicine) likely resulted from the need to transport patients from satellite facilities to a hub hospital with neurologists on continuous standby. After adjustment for initial NIHSS score and age, both groups achieved similar percentages of patients with modified Rankin Scale (mRS) scores of 0-2 at discharge: 58.5% for in-person evaluation versus 61.9% for telemedicine (P = .028).

A retrospective analysis of Medicare data revealed that between 2000 and 2017, immunohistochemistry (IHC) claims associated with melanoma diagnoses grew from 11% to 51%. Rising utilization — and substantial geographic variation in practice patterns — argue for further research to optimize IHC use in the diagnoses of melanoma, according to the authors.

But with sparse guidance regarding best practices for IHC in melanoma diagnosis, concerns for appropriate use are rising, they wrote in their report, recently published in JAMA Dermatology.

Kenechukwu Ojukwu, MD, MPP, of the department of pathology and laboratory medicine, University of California, Los Angeles, and coinvestigators, searched the Surveillance, Epidemiology, and End Results (SEER)–Medicare database for incident in situ or invasive cutaneous melanoma in patients 65 years and older and accompanying IHC claims made during the month of diagnosis through 14 days afterward.

Among 132,547 melanomas in 116,117 patients, 43,396 (33%) had accompanying IHC claims. Such claims were less common with increasing age, declining from 44% in patients aged 65-74 years to 18% in patients 85 aged years and older. Although melanoma incidence increased throughout the period studied, melanoma mortality rates remained relatively stable.

By summary stage at diagnosis, IHC utilization ranged from 29% of in situ cases to 75% of distant cases. After the researchers controlled for year of diagnosis, IHC use was statistically significantly associated with all demographic, tumor, and geographic characteristics examined, except race and ethnicity. Across all the years of the study, regional usage ranged from a low of 22% in Detroit to a high of 44% in both Louisiana and San Jose-Monterey, California. Figures for 2017 ranged from 39% of cases in Kentucky and Atlanta to 68% in New Mexico.

[embed:render:related:node:268401]

“Given the extensive use of IHC in clinical practice,” the authors concluded, “studies examining the resulting outcomes of IHC on different domains, such as symptom burden, quality of life, and mortality, are crucial.”

The “notable” regional variation in IHC utilization suggests uncertainty about its optimal employment in clinical practice, and, they wrote, “these findings highlight the need for research to identify where IHC provides the most value and to develop guidelines regarding the appropriate use of IHC.”

In an accompanying JAMA Dermatology editorial, Alexandra Flamm, MD, wrote, “now is an exciting time to practice dermatopathology, with an increased number of ancillary tests, such as IHC, that can be used to diagnose malignant neoplasms more precisely and to more accurately determine prognosis and therapeutic options in this age of precision medicine”.

However, added Dr. Flamm, a dermatologist and dermatopathologist at New York University, New York City, the increasing number of ancillary tests is fueling awareness of appropriate use and the importance of ensuring high-quality, value-based healthcare. “With this increased scrutiny on the appropriateness of ancillary histopathologic testing within dermatopathology,” she wrote, “the need is growing for parameters that can be used to guide when to use IHC testing and other ancillary testing.” And using dermatopathologist-developed tools such as American Society of Dermatopathology guidelines for 11 IHC tests can help ensure that appropriate medical decision-making is taken into account when creating these tools, she added.

IHC Usage Growing

“The paper confirms what I already knew,” said Whitney High, MD, JD, who was not involved with the study and was asked to comment on the results. “Use of IHC in dermatopathology has increased substantially, and probably will continue to increase over time.” The societal burden of IHC costs represents a legitimate concern, said Dr. High, professor of dermatology and pathology and director of dermatopathology at the University of Colorado, Aurora.

“However,” he told this news organization, “the histologic diagnosis of melanoma is sometimes substantially subjective — and all physicians, including pathologists, even though they are not providing care in the physical presence of the patient, are fiduciaries.” If an IHC stain would meaningfully improve a patient’s care, he said, physicians should attempt to provide it, unless strictly disallowed by a payer. Controlling medical-care costs might be better left to professional societies to guide care standards over time, he noted.

A longitudinal study incorporating two validated patient-reported outcome (PRO) tools showed that compared with patients with epidermal chronic cutaneous graft-versus-host disease (GVHD), those with sclerotic and combination disease experienced worse symptoms and quality-of-life (QOL) impairment. Independent of potential confounders, these PROs moreover predicted non-relapse mortality for all three disease subtypes, making PROs potentially useful adjuncts for risk stratification and treatment decisions, the study authors said.

“These two findings highlight the importance of patient-reported outcomes in measuring this disease,” lead author Emily Baumrin, MD, MSCE, assistant professor of dermatology and medicine at the University of Pennsylvania, Philadelphia, told this news organization. The study was published online February 28 in JAMA Dermatology.

Baurmrin_Emily_PA_web.jpg

Symptoms and QOL

The investigators monitored 436 patients from the Chronic GVHD Consortium until December 2020. The Lee Symptom Scale (LSS) skin subscale was used to evaluate symptom burden and the Functional Assessment of Cancer Therapy–Bone Marrow Transplantation (FACT-BMT) was used to measure quality of life.

Patients with sclerotic GVHD and combination disease at diagnosis had significantly worse median LSS scores than did those with epidermal disease (25, 35, and 20 points, respectively; P = .01). Patients with sclerotic disease had worse median FACT-BMT scores versus those with epidermal involvement (104 versus 109 points, respectively; P = .08).

Although these scores improved with all skin subtypes, LSS skin subscale and FACT-BMT scores remained significantly worse (by 9.0 points and 6.1 points, respectively) for patients with combination and sclerotic disease versus those with epidermal disease after adjusting for potential confounders.

Regarding mortality, every 7-point worsening (clinically meaningful difference) in FACT-BMT score at diagnosis of skin chronic GVHD conferred 9.1% increases in odds of both all-cause mortality and non-relapse mortality, after adjustment for factors such as age and sex. Likewise, for every 11 points worsening (clinically meaningful difference) in LSS skin subscale scores at diagnosis, researchers observed odds increases of 10% in all-cause mortality and 16.4% in non-relapse mortality.

Because patients with combination disease had only slightly more epidermal body surface area (BSA) involvement but significantly higher symptom burden than the other subtypes, the authors added, combination disease may represent a distinct phenotype. “Since we’ve also shown that the severity of patient-reported outcomes is associated with mortality,” Dr. Baumrin said in the interview, “perhaps these patients are at the highest risk of mortality as well.”

[embed:render:related:node:267680]

A growing population

Although many might think of chronic GVHD as rare, she noted, the number of allogeneic hematopoietic cell transplant (HCT) survivors living in the United States is growing. In a modeling study published in October of 2013 in Biology of Blood and Marrow Transplantation, authors predicted that by 2030, this figure will reach 502,000 — about half of whom will develop chronic GVHD, she said.

With more HCTs being performed each year and ongoing improvements in supportive care, patients are living longer post transplant. “Therefore, many transplant survivors are being taken care of in the community outside of transplant centers.”

Accordingly, Dr. Baumrin said, study findings are relevant to dermatologists in academic and transplant centers and the community who provide skin cancer screenings or other dermatologic care for transplant recipients. “Upon diagnosis of chronic GVHD, the evaluation of disease burden by patient-reported outcome measures may assist in assessing disease severity and response to treatments over time — and to stratify patients at higher risk for mortality and communicate that back to transplant physicians.”

Incorporating PROs into clinical practice might prove especially helpful for patients with sclerotic chronic cutaneous GVHD. Currently, clinicians assess cutaneous GVHD clinically, using parameters including skin thickness. The National Institutes of Health (NIH) Skin Score, used in clinical trials, also measures BSA.

“The issue with sclerosis is, it’s hard to determine clinical severity based on physical examination alone,” Dr. Baumrin said. It can be difficult to quantify skin thickness and changes over time. “So it’s hard to detect improvements, which are often slow. Patient-reported outcome measures may be a more sensitive way to detect response to treatment than our clinical assessments, which are often crude for sclerotic disease.”

In a secondary analysis of the phase 2 clinical trial of belumosudil, a treatment for chronic GVHD, published in October 2022 in Transplantation and Cellular Therapy, response rate was around 30% measured by NIH Skin Score and 77% by PROs. “Our clinical examination in sclerotic type disease falls short in terms of determining therapeutic benefit. PROs might complement those clinical measures,” she said.

Future research will involve determining and validating which PROs matter most clinically and to patients, added Dr. Baumrin. Although widely used in evaluating transplant patients, LSS skin subscale and FACT-BMT scores may not represent patients’ experience of living with cutaneous chronic GVHD as effectively as might other tools such as the Dermatology Life Quality Index (DLQI) or Patient-Reported Outcomes Measurement Information System (PROMIS) measures, she explained.

Study strengths included authors’ use of well-validated PROs rather than novel unvalidated measures, Sandra A. Mitchell, PhD, CRNP, of the National Cancer Institute, Rockville, Maryland, and Edward W. Cowen, MD, MHSc, of the Dermatology Branch at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), Bethesda, Maryland, wrote in an accompanying editorial in JAMA Dermatology. However, they added, incorporating causes of death might have revealed that the excess mortality associated with sclerotic disease stemmed at least partly from adverse effects of prolonged immunosuppression, particularly infection.

If future studies establish this to be the case, said Dr. Baumrin, reducing immunosuppression might be warranted for these patients. “And if death is primarily due to chronic GVHD itself, maybe we should treat more aggressively. PROs can help guide this decision.”

The study was supported by the NIH/NIAMS and the University of Pennsylvania. Dr. Baumrin and three coauthors report no relevant financial relationships; other authors had disclosures related to several pharmaceutical companies. Dr. Mitchell and Dr. Cowen had no disclosures.

The investigators monitored 436 patients from the Chronic GVHD Consortium until December 2020. The Lee Symptom Scale (LSS) skin subscale was used to evaluate symptom burden and the Functional Assessment of Cancer Therapy–Bone Marrow Transplantation (FACT-BMT) was used to measure quality of life.

Patients with sclerotic GVHD and combination disease at diagnosis had significantly worse median LSS scores than did those with epidermal disease (25, 35, and 20 points, respectively; P = .01). Patients with sclerotic disease had worse median FACT-BMT scores versus those with epidermal involvement (104 versus 109 points, respectively; P = .08).

Although these scores improved with all skin subtypes, LSS skin subscale and FACT-BMT scores remained significantly worse (by 9.0 points and 6.1 points, respectively) for patients with combination and sclerotic disease versus those with epidermal disease after adjusting for potential confounders.

Regarding mortality, every 7-point worsening (clinically meaningful difference) in FACT-BMT score at diagnosis of skin chronic GVHD conferred 9.1% increases in odds of both all-cause mortality and non-relapse mortality, after adjustment for factors such as age and sex. Likewise, for every 11 points worsening (clinically meaningful difference) in LSS skin subscale scores at diagnosis, researchers observed odds increases of 10% in all-cause mortality and 16.4% in non-relapse mortality.

Because patients with combination disease had only slightly more epidermal body surface area (BSA) involvement but significantly higher symptom burden than the other subtypes, the authors added, combination disease may represent a distinct phenotype. “Since we’ve also shown that the severity of patient-reported outcomes is associated with mortality,” Dr. Baumrin said in the interview, “perhaps these patients are at the highest risk of mortality as well.”

A growing population

Although many might think of chronic GVHD as rare, she noted, the number of allogeneic hematopoietic cell transplant (HCT) survivors living in the United States is growing. In a modeling study published in October of 2013 in Biology of Blood and Marrow Transplantation, authors predicted that by 2030, this figure will reach 502,000 — about half of whom will develop chronic GVHD, she said.

With more HCTs being performed each year and ongoing improvements in supportive care, patients are living longer post transplant. “Therefore, many transplant survivors are being taken care of in the community outside of transplant centers.”

Accordingly, Dr. Baumrin said, study findings are relevant to dermatologists in academic and transplant centers and the community who provide skin cancer screenings or other dermatologic care for transplant recipients. “Upon diagnosis of chronic GVHD, the evaluation of disease burden by patient-reported outcome measures may assist in assessing disease severity and response to treatments over time — and to stratify patients at higher risk for mortality and communicate that back to transplant physicians.”

Incorporating PROs into clinical practice might prove especially helpful for patients with sclerotic chronic cutaneous GVHD. Currently, clinicians assess cutaneous GVHD clinically, using parameters including skin thickness. The National Institutes of Health (NIH) Skin Score, used in clinical trials, also measures BSA.

“The issue with sclerosis is, it’s hard to determine clinical severity based on physical examination alone,” Dr. Baumrin said. It can be difficult to quantify skin thickness and changes over time. “So it’s hard to detect improvements, which are often slow. Patient-reported outcome measures may be a more sensitive way to detect response to treatment than our clinical assessments, which are often crude for sclerotic disease.”

In a secondary analysis of the phase 2 clinical trial of belumosudil, a treatment for chronic GVHD, published in October 2022 in Transplantation and Cellular Therapy, response rate was around 30% measured by NIH Skin Score and 77% by PROs. “Our clinical examination in sclerotic type disease falls short in terms of determining therapeutic benefit. PROs might complement those clinical measures,” she said.

Future research will involve determining and validating which PROs matter most clinically and to patients, added Dr. Baumrin. Although widely used in evaluating transplant patients, LSS skin subscale and FACT-BMT scores may not represent patients’ experience of living with cutaneous chronic GVHD as effectively as might other tools such as the Dermatology Life Quality Index (DLQI) or Patient-Reported Outcomes Measurement Information System (PROMIS) measures, she explained.

Study strengths included authors’ use of well-validated PROs rather than novel unvalidated measures, Sandra A. Mitchell, PhD, CRNP, of the National Cancer Institute, Rockville, Maryland, and Edward W. Cowen, MD, MHSc, of the Dermatology Branch at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), Bethesda, Maryland, wrote in an accompanying editorial in JAMA Dermatology. However, they added, incorporating causes of death might have revealed that the excess mortality associated with sclerotic disease stemmed at least partly from adverse effects of prolonged immunosuppression, particularly infection.

If future studies establish this to be the case, said Dr. Baumrin, reducing immunosuppression might be warranted for these patients. “And if death is primarily due to chronic GVHD itself, maybe we should treat more aggressively. PROs can help guide this decision.”

The study was supported by the NIH/NIAMS and the University of Pennsylvania. Dr. Baumrin and three coauthors report no relevant financial relationships; other authors had disclosures related to several pharmaceutical companies. Dr. Mitchell and Dr. Cowen had no disclosures.

When pediatric patients with epilepsy shift to adult care, inherent challenges are complicated by a near-total lack of efforts to smooth the transition, according to a recent survey. Many respondents received little to no information regarding the process, and many adults were still receiving care from family physicians or pediatric neurologists. The study was published online in Epilepsy & Behavior.

Room for Improvement

“We are not doing as good a job with planning for transition as we should,” said Elaine C. Wirrell, MD, who was not involved with the study. “It is not just a simple issue of sending your patient to an adult neurologist. Transition is a process that happens over time, so we need to do a better job getting our families ready for moving on to an adult provider.” Dr. Wirrell is director of pediatric epilepsy and professor of neurology at the Mayo Clinic in Rochester, Minnesota.

Clumsy Transitions

Investigators distributed a 25-question survey to patients and caregivers who attended the 2019 Epilepsy Awareness Day at Disneyland, and through online support groups in North America. Among 58 responses, 32 came from patients between ages 12 and 17 years or their caregivers.

Despite attempts to recruit a diverse cross-section of respondents, most patients had severe epilepsy and comorbidities: 43% had daily or weekly seizures; 45% were on three or more antiseizure medications; and 74% had intellectual disabilities.

Many children with early-life epilepsies suffer from developmental and epileptic encephalopathy, which has associated non-seizure symptoms including learning challenges, behavioral issues, and other medical concerns, Dr. Wirrell said. Therefore, she said, finding a neurologist who treats adults — and has the expertise and interest to care for such patients — can be difficult.

“We’re seeing many patients not making that transition, or maybe not making it appropriately, so they’re not necessarily getting to the providers who have the most expertise in managing their epilepsy.” Among adults surveyed, 27% were still being followed by pediatric neurologists, and 35% were visiting family doctors for epilepsy-related treatment.

Because the needs of children with complex epilepsy can extend well beyond neurology, Dr. Wirrell added, managing such cases often requires multidisciplinary pediatric teams. “Finding that team on the adult side is more challenging.” As a result, she said, patients may transfer their neurology care without getting additional support for comorbidities such as mood disorders and learning disabilities.

The foregoing challenges are complicated by the fact that pediatric neurologists often lack the time (and in the United States, reimbursement) to adequately address the transition process, said Dr. Wirrell. Providers in freestanding children’s hospitals may face additional challenges coordinating with adult-care providers outside their facilities, she said.

“There’s also potentially a reluctance of both families and physicians to transition the patient on, because there’s concern that maybe there isn’t anybody on the adult side who is able to do as good a job as what they have on the pediatric side.”
 

Well-Coordinated Transitions Should Have No Surprises

Transition should be a planned, independence-promoting process that results in smooth, well-coordinated movement of pediatric patients into adult care — one without surprises or disconnections, the authors wrote. However, 55% of respondents never heard the term “transition” from any provider, even though 69% of patients were being treated in academic specialty centers.

Among 12- to 17-year-olds, 72% had never discussed transition with their healthcare team. That figure includes no 17-year-olds. Approximately 90% of respondents said they received sufficient time during healthcare visits, but 54% reported feeling stressed when moving from pediatric to adult care.

Given resource constraints in many pediatric epilepsy programs, the study authors recommended patient-empowerment tools such as a transition toolkit to help patients and families navigate the transition process even in places without formal transition programs.

“Many of these children are coming over with boatloads of medical records,” Dr. Wirrell said. “It’s not fair to the adult provider, who then has to go through all those records.” Instead, she said, pediatric teams should provide succinct summaries of relevant test results, medication side effects, prior treatments tried, and the like. “Those summaries are critically important so that we can get information to the person who needs it.”

Although successful transition requires significant coordination, she added, much of the process can often be handled by nonphysicians. “There are some very good nurse-led transition programs. Often, we can have a nurse providing education to the family and even potentially having a joint visit with an adult epilepsy nurse for complex patients.”

Pediatric providers also must know when to begin the transition process, Dr. Wirrell said. As soon as patients are 13 or 14 years old, she suggested discussing the process with them and their families every 6 to 12 months, covering specifics ranging from how to order medications to why adult patients may need power of attorney designees.

On a broader scale, said Dr. Wirrell, a smooth handoff requires planning. Fortunately, she said, the topic is becoming a significant priority for a growing number of children’s hospitals specific not only to epilepsy, but also to other chronic illnesses.
