Incarceration versus treatment takes center stage in a new analysis of U.S. data from researchers in the United Kingdom.

The researchers performed an observational study looking at rates of incarceration, income, and drug-related deaths from 1983 to 2014 in the United States. They found a strong association between incarceration rates and drug-related deaths. Also, a very strong association was found between lower household income and drug-related deaths. Strikingly, in the counties with the highest incarceration rates, there was a 50% higher rate of drug deaths, reported Elias Nosrati, PhD, and associates (Lancet Public Health. 2019 Jul 3;4:e326-33). It is clearer every day that our opioid epidemic was in part wrought by a zealous push to change protocols on treating chronic pain. The epidemic also appears tied to well-meaning but overprescribing doctors and allegedly unscrupulous pharmaceutical companies and distributors. What we are learning through this most recent study is that another factor tied to the opioid and overdose epidemic could be incarceration.

According to the study, an increase in crime rates combined with sentencing reforms led the number of people incarcerated in state and federal prisons to soar from less than 200,000 in 1970 to almost 1 million in 1995. Furthermore, Dr. Nosrati and associates wrote, “Incarceration is directly associated with stigma, discrimination, poor mental health, and chronic economic hardship, all of which are linked to drug use disorders.”

Treatment for drug addiction in prison systems is rare, as is adequate mental health treatment. However, treatment for this population would likely help reduce drug overdose deaths and improve the quality of life for people who are incarcerated and their families. In the Philadelphia prison system, for example, treatment for inmates is available for opioid addiction, both with methadone and now more recently with buprenorphine (Suboxone). The Philadelphia Department of Prisons also provides cognitive-behavioral therapy. In Florida, Chapter 397 of the Florida statutes – known as the Marchman Act – provides for the involuntary (and voluntary) treatment of individuals with substance abuse problems.

The court systems in South Florida have a robust drug-diversion program, aimed at directing people facing incarceration for drug offenses into treatment instead. North Carolina has studied this issue specifically and found through a model simulation that diverting 10% of drug-abusing offenders out of incarceration into treatment would save $4.8 billion in legal costs for North Carolina counties and state legal systems. Diverting 40% of individuals would close to triple that savings.

There are striking data from programs treating individuals who are leveraged into treatment in order to maintain professional licenses. These such individuals, many of whom are physicians, airline pilots, and nurses, have a rate of sobriety of 90% or greater after 5 years. This data show that leveraged treatment has teeth and that those success rates are close to double the rates found within the general population.

In addition to the potential reduction in morbidity and mortality as well as the financial savings, why is treatment important? Because of societal costs. When parents or family members are put in jail for a drug charge or other charge, they leave behind a community, family, and very often children who are affected economically, emotionally, and socially. Those children in particular have higher risks of depression and PTSD. Diverting an offender into treatment or treating an incarcerated person for drug and mental health problems can change the life of a child or family member, and ultimately can change society.

The Food and Drug Administration has revised its 2017 guidance on fish consumption.

Lynda Banzi/MDedge News

The revision touts the health benefits of fish and shellfish and promotes safer fish choices for those who should limit mercury exposure – including women who are or might become pregnant, women who are breastfeeding, and young children.

Those individuals should avoid commercial fish with the highest levels of mercury and should instead choose from “the many types of fish that are lower in mercury – including ones commonly found in grocery stores, such as salmon, shrimp, pollock, canned light tuna, tilapia, catfish, and cod,” according to an FDA press statement.

The potential health benefits of eating fish were highlighted in the U.S. Department of Health and Human Services/Department of Agriculture 2015-2020 Dietary Guidelines for Americans, and in 2017 the FDA and the Environmental Protection Agency released advice on fish consumption, including a user-friendly reference chart regarding mercury levels in various types of fish.

Although the information in the chart has not changed, the FDA revised its advice to expand on the “information about the benefits of fish as part of healthy eating patterns by promoting the science-based recommendations of the 2015-2020 Dietary Guidelines for Americans.”

The advice calls for consumption of at least 8 ounces of seafood per week for adults (less for children) based on a 2,000 calorie diet, and for women who are pregnant or breastfeeding, 8-12 ounces of a variety of seafood per week selected from choices lower in mercury.

“The FDA’s revised advice highlights the many nutrients found in fish, several of which have important roles in growth and development during pregnancy and early childhood. It also highlights the potential health benefits of eating fish as part of a healthy eating pattern, particularly for improving heart health and lowering the risk of obesity,” the press release states.

Despite these benefits – and the recommendations for intake – concerns about mercury in fish have led many pregnant women in the United States to consume far less than the recommended amount of seafood, according to Susan Mayne, PhD, director of the FDA’s Center for Food Safety and Applied Nutrition.

“Our goal is to make sure Americans are equipped with this knowledge so that they can reap the benefits of eating fish, while choosing types of fish that are safe for them and their families to eat,” Dr. Mayne said in the FDA statement.

In response to the revised guidance, John S. Cullen, MD, president of the American Academy of Family Physicians, said that all women should be counseled to eat a well-balanced and varied diet including meats, dairy products, fruits, vegetables, and grains, and pregnant women should limit their intake of fish and seafood products to 8-12 ounces, or about 2-3 fish meals, per week.

Pregnant women may eat salmon in moderation, but should avoid raw seafood of any type because of possible contamination with parasites and Norwalk-like viruses, he said, adding that seafood like shark, swordfish, king mackerel, tilefish, Bigeye (Ahi) tuna steaks, and other long-lived fish high on the food chain should be avoided completely because of high mercury levels.

“While the AAFP did not review the revised advice to the dietary guidelines, family physicians are on the front lines encouraging healthy nutrition for pregnant and breastfeeding women and young children. It’s an ongoing, important part of the patient-physician conversation that begins with the initial prenatal visit,” Dr. Cullen said in a statement.

Similarly, Christopher M. Zahn, MD, vice president of practice activities for the American College of Obstetricians and Gynecologists, said the FDA/EPA updated guidance is in line with ACOG recommendations.

“The guidance continues to underscore the value of eating seafood 2-3 times per week during pregnancy and the importance of avoiding fish products that are high in mercury. The additional emphasis on healthy eating patterns mirrors ACOG’s long-standing guidance on the importance of a well-balanced, varied, nutritional diet that is consistent with a woman’s access to food and food preferences,” he said in a statement, noting that “seafood is a nutrient-rich food that has proven beneficial to women and in aiding the development of a fetus throughout pregnancy.”

PHILADELPHIA – Administering tranexamic acid to patients with traumatic brain injury (TBI) before they are admitted to the hospital does not improve neurologic outcomes, according to an investigation presented at the annual meeting of the American Academy of Neurology. For patients with TBI and intracranial hemorrhage (ICH), however, treatment with a 2-gram bolus of tranexamic acid within 42 minutes of injury significantly improves the rate of 28-day survival. Tranexamic acid therefore “is the first therapeutic with evidence for benefit in acute TBI,” said Susan Rowell, MD, trauma medical director at Duke University in Durham, North Carolina.

No effective treatment is available for TBI, which is a major cause of death after trauma. In 2010, the CRASH-2 trial (Lancet. 2010 Jul 03;376[9734]:23-32), suggested that tranexamic acid, a lysine analogue that decreases the breakdown of clots, safely reduced the rate of death from hemorrhage in patients with trauma and bleeding. Patients treated within 1 hour of injury were significantly more likely to survive than those treated at 1 hour or more after injury.

Two small, prospective trials failed to show that tranexamic acid reduced in-hospital mortality, improved neurologic function at discharge, or reduced the progression of ICH. A meta-analysis of both trials, however, showed a trend toward a benefit of treatment with this therapy.
 

A multicenter, prehospital trial

Dr. Rowell and colleagues hypothesized that prehospital administration of tranexamic acid to patients with moderate to severe TBI early after injury would increase the likelihood of a favorable neurologic outcome. Between March 2015 and March 2017, they enrolled 1,280 participants in a multicenter, prehospital trial. Eligible participants had moderate to severe TBI, were not in shock (as evidenced by a systolic blood pressure greater than 90 mm Hg before randomization), and were enrolled within 2 hours of injury.

Patients were randomized to one of three treatment arms and followed for 6 months. The first treatment arm received a 1-gram bolus of tranexamic acid before hospital admission and an 8-hour, 1-gram infusion of tranexamic acid in the hospital. The second arm received a 2-gram bolus of tranexamic acid before hospital admission and a placebo infusion in the hospital. The third arm received a placebo bolus and placebo infusion. Paramedics and participants were blinded to treatment assignment. The trial was conducted at 20 hospitals and 39 emergency medical services agencies in the United States and Canada.

The study’s primary outcome was functional neurologic outcome at 6 months, as measured by the Glasgow Outcomes Scale – Extended (GOSE). The investigators dichotomized results into favorable and poor categories. Other prespecified outcomes included early and late mortality, the disability rating scale (DRS), and progression of ICH.
 

Treatment was administered early

The researchers identified 1,280 eligible patients, of whom 1,063 were randomized. The modified intention-to-treat analysis included 309 participants in the placebo group, 312 in the bolus-maintenance group (the 1-gram group), and 345 in the bolus-only group (the 2-gram group). The population’s average age was approximately 42 years, and 75% of the sample was male. About half of the patients had a Glasgow Coma Scale score between 3 and 8. Injury severity and prehospital care were similar among the groups.

The researchers provided the drug infusion at an average of 0.7 hours (42 minutes) after injury, “which is actually quite early,” said Dr. Rowell. They observed few infusion-related deviations, and the entire bolus was infused in about 95% of patients. Approximately 70% of patients received the full 8-hour infusion. This result was influenced partly by stopping rules and by providers who requested unblinding to give open-label tranexamic acid. Overall, 57% of patients in the trial had an ICH on head CT, which was approximately the proportion that the researchers had anticipated.

Dr. Rowell and colleagues completed the 6-month follow-up for 85% of patients. They saw no difference in the 6-month neurologic outcome between the group of all patients who received tranexamic acid and those who received placebo. The investigators also saw no differences between groups in early and late mortality and the DRS.

About half of patients with ICH were evaluated for progression. Progression occurred in 20% of the placebo arm, 17% of the bolus-maintenance arm, and 15% of the bolus-only arm. The differences between groups were not statistically significant. Participants in the bolus-only group, however, were significantly less likely to die, compared with the placebo and the bolus-maintenance groups. The odds ratio of death for the bolus-only group, compared with the others, was about 0.5. The absolute mortality rate for the placebo and bolus-maintenance groups was 17%, compared with 12% for the bolus-only group. Most deaths were attributable to TBI, and few patients died of exsanguination.

In addition, the bolus-only group also had improved long-term neurologic outcome, as assessed by the 6-month DRS and the 6-month GOSE, compared with the bolus maintenance group.

Among patients with ICH, survival increased by approximately 12% at 10 hours after injury in the bolus-only group, compared with the bolus-maintenance and placebo groups. This difference persisted throughout the follow-up period, said Dr. Rowell.

Among predefined major adverse events, seizure-like activity occurred in 5% of the bolus-only group, compared with 2% of the placebo and bolus-maintenance groups. The researchers found no significant differences in any thrombotic event between the bolus-only group and the placebo group.

The study was sponsored by University of Washington, Seattle. Collaborators included the National Heart, Lung, and Blood Institute; the U.S. Army Medical Research and Development Command; and the American Heart Association. Dr. Rowell had no relevant disclosures.

For patients with TBI and intracranial hemorrhage (ICH), however, treatment with a 2-gram bolus of tranexamic acid within 42 minutes of injury significantly improves the rate of 28-day survival. Tranexamic acid therefore “is the first therapeutic with evidence for benefit in acute TBI,” said Susan Rowell, MD, trauma medical director at Duke University in Durham, North Carolina.

No effective treatment is available for TBI, which is a major cause of death after trauma. In 2010, the CRASH-2 trial (Lancet. 2010 Jul 03;376[9734]:23-32), suggested that tranexamic acid, a lysine analogue that decreases the breakdown of clots, safely reduced the rate of death from hemorrhage in patients with trauma and bleeding. Patients treated within 1 hour of injury were significantly more likely to survive than those treated at 1 hour or more after injury.

Two small, prospective trials failed to show that tranexamic acid reduced in-hospital mortality, improved neurologic function at discharge, or reduced the progression of ICH. A meta-analysis of both trials, however, showed a trend toward a benefit of treatment with this therapy.
 

A multicenter, prehospital trial

Dr. Rowell and colleagues hypothesized that prehospital administration of tranexamic acid to patients with moderate to severe TBI early after injury would increase the likelihood of a favorable neurologic outcome. Between March 2015 and March 2017, they enrolled 1,280 participants in a multicenter, prehospital trial. Eligible participants had moderate to severe TBI, were not in shock (as evidenced by a systolic blood pressure greater than 90 mm Hg before randomization), and were enrolled within 2 hours of injury.

Patients were randomized to one of three treatment arms and followed for 6 months. The first treatment arm received a 1-gram bolus of tranexamic acid before hospital admission and an 8-hour, 1-gram infusion of tranexamic acid in the hospital. The second arm received a 2-gram bolus of tranexamic acid before hospital admission and a placebo infusion in the hospital. The third arm received a placebo bolus and placebo infusion. Paramedics and participants were blinded to treatment assignment. The trial was conducted at 20 hospitals and 39 emergency medical services agencies in the United States and Canada.

The study’s primary outcome was functional neurologic outcome at 6 months, as measured by the Glasgow Outcomes Scale – Extended (GOSE). The investigators dichotomized results into favorable and poor categories. Other prespecified outcomes included early and late mortality, the disability rating scale (DRS), and progression of ICH.
 

Treatment was administered early

The researchers identified 1,280 eligible patients, of whom 1,063 were randomized. The modified intention-to-treat analysis included 309 participants in the placebo group, 312 in the bolus-maintenance group (the 1-gram group), and 345 in the bolus-only group (the 2-gram group). The population’s average age was approximately 42 years, and 75% of the sample was male. About half of the patients had a Glasgow Coma Scale score between 3 and 8. Injury severity and prehospital care were similar among the groups.

The researchers provided the drug infusion at an average of 0.7 hours (42 minutes) after injury, “which is actually quite early,” said Dr. Rowell. They observed few infusion-related deviations, and the entire bolus was infused in about 95% of patients. Approximately 70% of patients received the full 8-hour infusion. This result was influenced partly by stopping rules and by providers who requested unblinding to give open-label tranexamic acid. Overall, 57% of patients in the trial had an ICH on head CT, which was approximately the proportion that the researchers had anticipated.

Dr. Rowell and colleagues completed the 6-month follow-up for 85% of patients. They saw no difference in the 6-month neurologic outcome between the group of all patients who received tranexamic acid and those who received placebo. The investigators also saw no differences between groups in early and late mortality and the DRS.

About half of patients with ICH were evaluated for progression. Progression occurred in 20% of the placebo arm, 17% of the bolus-maintenance arm, and 15% of the bolus-only arm. The differences between groups were not statistically significant. Participants in the bolus-only group, however, were significantly less likely to die, compared with the placebo and the bolus-maintenance groups. The odds ratio of death for the bolus-only group, compared with the others, was about 0.5. The absolute mortality rate for the placebo and bolus-maintenance groups was 17%, compared with 12% for the bolus-only group. Most deaths were attributable to TBI, and few patients died of exsanguination.

In addition, the bolus-only group also had improved long-term neurologic outcome, as assessed by the 6-month DRS and the 6-month GOSE, compared with the bolus maintenance group.

Among patients with ICH, survival increased by approximately 12% at 10 hours after injury in the bolus-only group, compared with the bolus-maintenance and placebo groups. This difference persisted throughout the follow-up period, said Dr. Rowell.

Among predefined major adverse events, seizure-like activity occurred in 5% of the bolus-only group, compared with 2% of the placebo and bolus-maintenance groups. The researchers found no significant differences in any thrombotic event between the bolus-only group and the placebo group.

The study was sponsored by University of Washington, Seattle. Collaborators included the National Heart, Lung, and Blood Institute; the U.S. Army Medical Research and Development Command; and the American Heart Association. Dr. Rowell had no relevant disclosures.

Louisiana physicians who treat Medicaid patients for hepatitis C will see less administrative burden under an arrangement approved by the Centers for Medicare & Medicaid Services.

Dynamic Graphics/Thinkstockphotos

Beginning July 15, physicians will no longer have to seek prior authorization or preauthorization to prescribe the authorized generic version of Epclusa (sofosbuvir/velpatasvir) to any Medicaid patient with hepatitis C. There will be no forms to file.

The change comes as part of a supplemental rebate agreement approved June 26 by CMS. That same day, Louisiana announced a deal with Asegua Therapeutics, a wholly owned subsidiary of Epclusa maker Gilead, that essentially caps the annual cost to the state for treating hepatitis C in incarcerated patients and Medicaid recipients.

State officials estimate about 39,000 Louisianans fit those criteria; the goal of the program is to cure at least 31,000 of them by the time the 5-year agreement expires.

“This new model has the potential to save many lives and improve the health of our citizens,” Louisiana Gov. John Bel Edwards (D) said in a statement. “Asegua was willing to come to the table to work with us to help Louisiana residents and we are pleased to initiate this 5-year partnership. Ultimately our goal is to eliminate this disease in Louisiana, and we have taken a big step forward in that effort.”

The agreement was designed to change very little in terms of the mechanics of how Medicaid managed care organizations, which cover most of the state’s Medicaid population and handle coverage and claims. The biggest change is that, when a spending cap is reached, Asegua will rebate 100% excess costs to the state. Louisiana officials did not disclose what the annual financial caps were as part of the agreement.

“We really thought it was important to leave the system – as much as possible – intact because we think that is going to make us most successful,” Alex Billioux, MD, of the Louisiana Department of Health said in an interview. “We think it leverages existing patient relationships and existing [Medicaid managed care organization] care management responsibilities.”

He added that, by keeping current processes unchanged, “it takes what is an otherwise very complicated arrangement with the state and makes it a little simpler.”

Patients will see no change in terms of copayments for the approved generic topping out at $3 depending on income level as they would have prior to the agreement. The biggest difference for them is that “people who couldn’t be treated are now going to have access to those prescriptions,” Dr. Billioux said.

Some cautious optimism surrounds this kind of arrangement and the potential effect it can have on the affected population.

“Innovation geared to improve access to hepatitis C treatment is critical, particularly in areas like Louisiana where treatment rates for Medicaid patients have been very low,” Robert Brown, MD, member of the American Liver Foundation’s National Medical Advisory Committee and hepatologist at Weill Cornell Medical College, New York, said. “If we can enhance patient access to treatment, we know we will improve health outcomes. However, it is too early to tell if this innovation will be a success. At the end of the day, the number of additional patients cured will determine if this was the right approach.”

SAN DIEGO – The prevalence of obstructive sleep apnea (OSA) is substantially lower using the Centers for Medicare & Medicaid Services apnea-hypopnea index definition of OSA than using the one recommended by the American Academy of Sleep Medicine.

Doug Brunk/MDedge News

In addition, among individuals who did not have OSA using the CMS definition but met criteria using the AASM definition of OSA, an apnea-hypopnea index (AHI) of five events or greater per hour was associated with a greater likelihood of having hypertension.

The findings come from an analysis which set out to assess the relationship between OSA and hypertension using the AASM-recommended definition and the 2018 American Heart Association/American College of Cardiology blood pressure guidelines, and to determine if there is an association between hypertension and OSA among individuals who did not meet the CMS definition of OSA.

“Given the substantial morbidity associated with hypertension, these results suggest that universal adoption of the AASM AHI definition would be a reasonable step in ensuring appropriate diagnosis and treatment of OSA,” lead study author Stuart F. Quan, MD, said at the annual meeting of the Associated Professional Sleep Societies.

Dr. Quan, of the division of sleep and circadian disorders at Brigham and Women’s Hospital in Boston, noted that a number of studies have demonstrated that OSA is a risk factor for hypertension and a variety of other medical conditions. “Rightly or wrongly, the most important metric for determining whether OSA is present and determining its severity, is the apnea-hypopnea index,” he said. “It’s the most common metric used for determining OSA severity, and mostly importantly, Medicare and some other insurers use this metric to determine whether a person is eligible for treatment. If a person falls above the line, they can get continuous positive airway pressure, for example. If they’re below the line, that’s too bad; they don’t have OSA insofar as the insurance company is concerned.”

There is no controversy as to what constitutes apnea, he continued, but some disagreement exists on the definition of hypopnea. The AASM recommends using a 3% oxygen desaturation or an arousal, while Medicare uses a definition of hypopnea requiring only a 4% oxygen desaturation. Hypertension definitions have changed recently as well. Before 2018, the definition of hypertension was greater than 140/90 mm Hg for people younger than age 65 years and 150/80 mm Hg for people age 65 years and older. In 2018, the AHA and ACC changed the hypertension guidelines, defining normal as less than 120/80 mm Hg.

“Previous studies linking OSA and hypertension used older definitions, but to my knowledge there are no current studies examining the association between OSA and hypertension using new definitions,” Dr. Quan said.

He reported on results from an analysis of 6,307 participants in the Sleep Heart Health Study who underwent home polysomnography. Their AHI defined by a 3% oxygen desaturation or an arousal was classified into four categories of OSA severity: fewer than 5 events per hour (normal sleep), 5-14 events per hour (mild sleep apnea), 15-29 events per hour (moderate sleep apnea), and 30 or more events per hour (severe sleep apnea).

The researchers used three definitions of dichotomous BP elevation: elevated (greater than 120/80 mm Hg or use of hypertension medications [meds]), stage 1 (greater than 130/80 mm Hg or meds), or stage 2 (greater than 140/90 mm Hg or meds). They used logistic regression to assess the association between elevated BP and/or hypertension and OSA severity, controlling for demographics and body mass index. Additional analyses utilized multiple linear regression to determine the relationship between natural log AHI and systolic and diastolic BP, controlling for the same covariates.

For all definitions of elevated BP, increasing OSA severity was associated with greater likelihood of an elevated or hypertensive status in fully adjusted models. Specifically, the odds ratios among those with elevated BP was 1.30 (95% confidence interval, 1.10-1.54), 1.41 (95% CI, 1.15-1.72), and 1.69 (95% CI, 1.32-2.17) for mild, moderate, and severe sleep apnea, respectively. The ORs among those with stage 1 BP was 1.27 (95% CI, 1.09-1.49), 1.36 (95% CI, 1.13-1.63), 1.58 (95% CI, 1.27-1.97) for mild, moderate, and severe sleep apnea, while the OR among those with stage 2 BP was 1.07 (95% CI, 0.92-1.26), 1.22 (95% CI, 1.02-1.45), 1.38 (95% CI, 1.12-1.69) for mild, moderate, and severe sleep apnea. Linear regression found that AHI was associated with both systolic and diastolic BP in fully adjusted models.

“Using the AASM and CMS AHI definitions, increasing severity of AHI is associated with greater likelihood of having an elevated blood pressure or hypertension,” Dr. Quan concluded. “However, the prevalence of OSA was substantially lower using the CMS definition of OSA. In fact, 218 of these individuals had moderate to severe OSA when the AASM definition was applied.”

He characterized the study as “a practical analysis, a way to help identify patients who might benefit from treatment. This is not the issue of whether the science of 3% AHI is better than 4%.”

The Sleep Heart Health Study was supported by the National Heart, Lung, and Blood Institute. Dr. Quan reported that he helped draft the AASM AHI recommendations but had no other relevant disclosures.

Isotretinoin use may increase vulnerability to psychiatric conditions, but available evidence does not support a causal relationship, on the basis of data from a retrospective study of 17,829 psychiatric adverse events reported to the Food and Drug Administration over 2 decades.

“Although one study highlighted consistent reporting of depression and suicide in patients taking isotretinoin in the United States from 1982 to 2000, few studies have examined reports of psychiatric adverse events at the national level since 2000,” wrote Sean Singer of Harvard University, Boston, and his colleagues.

In a study published in JAMA Dermatology, the researchers reviewed data from the FDA’s Adverse Event Reporting System between 1997 and 2017.

A total of 17,829 psychiatric adverse events in which isotretinoin was the primary suspect drug were reported during the study period. The researchers classified the events into 12 categories; the most common were depressive disorders (42%), emotional lability (17%), and anxiety (14%). The number of reported psychiatric adverse events was similar between men and women (8,936 and 8,362 events, respectively).

The researchers also identified 2,278 reports of suicidal ideation, 602 reports of attempted suicide, and 368 reports of completed suicide.

In addition, the researchers examined data from the iPLEDGE program and found completed suicide rates of 8.4 per 100,000 patients in 2009 and 5.6 per 100,000 patients in 2010. However, these rates were lower than national suicide rates in the general population of 11.8 per 100,000 people in 2009 and 12.1 per 100,000 people in 2010.

Patient age was available for 13,553 adverse event reports, and patients aged 10-19 years accounted for 53% of the reports overall and 58% of completed suicides for which age was reported.

The high number of psychiatric adverse events in the youngest age group “could reflect more isotretinoin prescriptions in this age group or may suggest that teenagers are particularly vulnerable to psychiatric adverse events while taking isotretinoin,” the researchers said.

The findings were limited by several factors, including the reliance on proper clinician reports to the Adverse Event Reporting System database and the separation of some psychiatric terms into categories that may reflect symptoms of other psychiatric diagnoses, the researchers said.

However, “Our data showed high numbers of reports of emotional lability, anxiety disorders, insomnia, self-injurious behavior, and psychotic disorders with isotretinoin as the primary suspect drug,” they noted.

“Although no causal link has been established between isotretinoin and psychiatric adverse events, it is important to recognize that there are data that suggest patients using this drug may be vulnerable to a number of psychiatric conditions” and that monthly iPLEDGE visits are an opportunity to screen patients for these conditions, they said.

They also stressed that “the risk of psychiatric adverse events in patients taking isotretinoin must be considered in the context of a known increased risk of suicidal ideation in patients with acne independent of isotretinoin therapy.”

Isotretinoin use may increase vulnerability to psychiatric conditions, but available evidence does not support a causal relationship, on the basis of data from a retrospective study of 17,829 psychiatric adverse events reported to the Food and Drug Administration over 2 decades.

“Although one study highlighted consistent reporting of depression and suicide in patients taking isotretinoin in the United States from 1982 to 2000, few studies have examined reports of psychiatric adverse events at the national level since 2000,” wrote Sean Singer of Harvard University, Boston, and his colleagues.

In a study published in JAMA Dermatology, the researchers reviewed data from the FDA’s Adverse Event Reporting System between 1997 and 2017.

MILAN – Health-related quality of life improved for patients with moderate to severe genital psoriasis while they received ixekizumab, according to data presented at the World Congress of Dermatology.

After 12 weeks of ixekizumab administration, nearly half of patients who received ixekizumab in the randomized, double-blind, placebo-controlled trial achieved a Dermatology Life Quality Index (DLQI) score of 0 or 1, compared with fewer than 5% of those receiving placebo. At the end of one year, 46.7% of the original ixekizumab group and 50.8% of those who transitioned to ixekizumab from placebo via an open-label extension arm achieved a DLQI of 0 or 1. A DLQI score of 0 or 1 on a 30-point scale indicated that psoriasis had no effect on health-related quality of life.

Among patients with plaque psoriasis, genital involvement is common – present in over 60% at some point during the disease course, Lyn Guenther, MD, of Guenther Dermatology Research Centre, London, Ont., and her colleagues wrote in the poster accompanying the presentation. Sexual health and overall quality of life can be negatively affected by genital psoriasis, they added.

In the study, adult patients were included if they had chronic plaque psoriasis present in genital and nongenital areas. For overall psoriasis and genital involvement, the Static Physician’s Global Assessment (sPGA) was 3 or greater, and total body surface area involvement was at least 1%. Also, patients had to have failed or been intolerant to at least one topical therapy for genital psoriasis.

Patients were excluded if they had genital pustules or vesicles, significant uncontrolled medical or psychiatric comorbidities, recent infection, or prior interleukin-17 antagonist treatment.

In all, patients received ixekizumab 160 mg (75 patients) or placebo (74) subcutaneously every 2 weeks during the initial 12-week study period. For the open-label extension arm, 74 patients in the active arm and 65 patients in the placebo arm went on to receive 80 mg of ixekizumab every 4 weeks, with a step-up option to every other week dosing depending on clinical response.

Patients were given the Short Form Health Survey (SF-36) at baseline and at week 12 and week 52; investigators recorded the mean change for baseline for both the physical and mental component.

Participants also completed the DLQI, which was administered nine times over the 52-week study period.

From baseline, SF-36 scores climbed in both the physical and mental domains for those on ixekizumab, wrote Dr. Guenther and her coinvestigators, with “improvements in all SF-36 domains” for those on ixekizumab at 12 weeks, which continued through week 52. For patients who transitioned to ixekizumab from placebo, “improvements in all SF-36 domains were achieved at week 52,” they wrote.

The mean change from baseline on the SF-36 for the ixekizumab population was 3.5 on the physical domain and 4.8 on the mental component. For the placebo-ixekizumab group, scores improved by a mean 4.5 on the physical domain and 4.9 on the mental domain. Those who stayed on ixekizumab saw some decline in SF-36 scores, with a physical component improvement of 2.5 and mental component improvement of 3.6 at 52 weeks.

Ixekizumab (Taltz), a monoclonal antibody targeting interleukin-17A, is approved for moderate to severe plaque psoriasis, and active psoriatic arthritis..

“Ixekizumab provided clinically meaningful and persistent improvements in HRQoL in patients with moderate to severe genital psoriasis,” wrote Dr. Guenther and her colleagues.

Dr. Guenther and two coauthors reported receiving remuneration from several pharmaceutical companies, including Eli Lilly, which funded the study. Four coauthors are employees and shareholders of Eli Lilly.

The tyrosine kinase inhibitor dasatinib was found to transiently inhibit CAR T-cell function in mice, suggesting applicability as an on-off control for CAR T-cell therapy, investigators report.

“In this study, we focused our efforts on evaluating dasatinib as a control drug for CAR T cells,” wrote Katrin Mestermann, PhD, of the University of Würzburg in Germany and colleagues in Science Translational Medicine.

The researchers explored the pharmacological effects of dasatinib on CAR T-cell function using a mouse xenograft model. In this model, dasatinib was administered every 6 hours to sustain serum levels above a mandatory threshold to ensure human pharmacokinetic equivalence.

The team observed that dasatinib interferes with several cellular mechanisms that effect CAR T-cell activity, including inhibition of protein phosphorylation and cytokine secretion, among others.

Short-term administration of dasatinib was shown to not alter antilymphoma activity of CD19-CAR T cells, according to data from in vivo experiments.

In addition, upon cessation of dasatinib, CAR T-cell antitumor activity was rapidly restored, based on in vitro experiment data.

Dr. Mestermann and her colleagues also noted that the dose of dasatinib was titratable to attain either partial or complete inhibition of CAR T-cell activity. These effects could be maintained for several days without altering T-cell survival.

“A short treatment course of dasatinib, administered early after CAR T-cell infusion, protects a proportion of mice from otherwise fatal cytokine release syndrome,” the researchers wrote.

Cytokine release syndrome is the most frequently seen acute toxicity linked to CAR T-cell therapy, they explained.

“Further studies are warranted to determine whether dasatinib is also effective in clinical situations with established cytokine release syndrome,” they concluded.

The study was funded by the Cluster Biotechnologie Bayern and Free State of Bavaria, the German Cancer Aid, and the University of Würzburg. The authors reported financial affiliations with Amgen, Bristol-Myers Squibb, Celgene, Janssen, Novartis, Takeda, and others.
