Both public and private health plans score poorly when it comes to providing access to autoimmune medication, according to a report commissioned by the Autoimmune Association and Let My Doctors Decide, a national partnership of health care professionals. The analysis, published Jan. 26, found that 75% of insurers in the United States have policies that can limit coverage for Food and Drug Administration–approved medications for Crohn’s disease, lupus nephritis, multiple sclerosis, psoriasis, psoriatic arthritis, rheumatoid arthritis, and ulcerative colitis.

“Choice among health plans is a hallmark of the American health insurance system, yet this analysis shows that people living with autoimmune conditions have few, if any, coverage choices that do not involve significant to severe access restrictions,” the authors wrote.

The study looked at three common utilization management policies by health plans that can limit coverage of certain medications: step therapy, formulary/tier placement, and prior authorization. To compare health plans, researchers weighted these policies using a point system. Each medication indicated for each condition was given a score of 0-4 based on access restrictions in a health plan. If a plan used step therapy, it received one point, and requiring prior authorization added an additional point. They also added points based on where a drug appeared on a plan’s formulary. A lower total score meant fewer access barriers. The numbers were then added, and each health plan received a grade of A, B, C, or F based on their average score. The datasets and analysis were provided and performed by the data analytics firm MMIT.

Nearly 9 in 10 Medicare plans received a C or worse for coverage of medication received via mail order or the pharmacy. In commercial plans, the majority of plans scored Cs or Fs for six of the seven conditions, excluding lupus nephritis, where 67% of all commercial health plans scored a B for access to these medications.

Physician-administered medications tended to receive poorer coverage than drugs received via pharmacy. Across all conditions, 65% of Medicare Advantage plans scored an F for physician-administered medication access. For both psoriasis and multiple sclerosis, at least 80% of Medicare plans earned failing scores because of these restrictions. Coverage was poorer on both commercial and health exchange plans, where across all conditions, 83% achieved failing scores. Two exceptions were the Southern and Northern California PPO plans by the Kaiser Foundation Health Plan. Out of the largest 25 health plans in the United States, these two plans earned As in coverage for physician-administered medications across all seven autoimmune conditions.

The report shows “a growing disconnect between science and health insurance benefit designs that were developed in the 1960s and 1970s,” Kenneth Thorpe, PhD, of Emory University, Atlanta, said in an interview. Insurers originally designed these benefits to prevent excessive utilization in a population of mostly acutely ill patients, he said, whereas now, 90% of healthcare spending is linked to chronic conditions. For these patients, research shows that incentivizing patients to adhere to medications results in fewer hospitalizations and, therefore, more cost savings, Thorpe noted. These plans also do not consider that there is no average patient, he said, and healthcare providers should be able to match each patient to the best treatment option for them rather than trying out other less expensive medications first. “To the extent that physicians can have the flexibility to provide medications and treatments to patients that are going to have the best clinical response, that’s better outcomes at lower cost,” Dr. Thorpe said. While research shows heterogeneity in patient outcomes with different medication, “benefit designs from the past just don’t recognize that.”

Neither America’s Health Insurance Plans nor Pharmaceutical Care Management Association responded to a request for comment.

Quardricos Driskell, executive director of Let My Doctors Decide and vice president of government relations and public policy at the Autoimmune Association, hopes the study will spur action by policy makers and health plans to improve access to medications for the people who need them. Another larger point of the report is to “uphold the sanctity of protecting the doctor and patient relationship,” he said in an interview, adding “that decisions fundamentally need to be made not by insurance plans or middleman pharmacy benefit managers, but by the provider and patient.”

Mr. Driskell and Dr. Thorpe reported no relevant financial relationships.

The rising national suicide rate is being driven by increases among younger people and among people of color, according to a new report. 

Significant increases in suicide occurred among Native American, Black and Hispanic people, with a startling rise among young Black people. Meanwhile, the rate of suicide among older people declined between 2018 and 2021, the Centers for Disease Control and Prevention has reported.

In 2021, 48,183 people died by suicide in the United States, which equates to a suicide rate of 14.1 per 100,000 people. That level equals the 2018 suicide rate, which had seen a peak that was followed by declines associated with the pandemic.

Experts said rebounding suicide rates are common following times of crisis, such as the COVID-19 pandemic. Suicide declines have also occurred during times of war and natural disaster, when psychological resilience tends to increase and people work together to overcome shared adversity.

“That will wane, and then you will see rebounding in suicide rates. That is, in fact, what we feared would happen. And it has happened, at least in 2021,” Christine Moutier, MD, chief medical officer of the American Foundation for Suicide Prevention, told the New York Times.

The new CDC report found that the largest increase was among Black people aged 10-24 years, who experienced a 36.6% increase in suicide rate between 2018 and 2021. While Black people experience mental illness at the same rates as that of the general population, historically they have disproportionately limited access to mental health care, according to the American Psychiatric Association.

CDC report authors noted that some of the biggest increases in suicide rates occurred among groups most affected by the pandemic. 

From 2018 to 2021, the suicide rate for people aged 25-44 increased among Native Americans by 33.7% and among Black people by 22.9%. Suicide increased among multiracial people by 20.6% and among Hispanic or Latinx people by 19.4%. Among White people of all ages, the suicide rate declined or remained steady.

“As the nation continues to respond to the short- and long-term impacts of the COVID-19 pandemic, remaining vigilant in prevention efforts is critical, especially among disproportionately affected populations where longer-term impacts might compound preexisting inequities in suicide risk,” the CDC researchers wrote.

At the time of a nephritis flare in patients with systemic lupus erythematosus (SLE), elevated levels of two neutrophil extracellular trap (NET) protein complexes, elastase-DNA and HMGB1-DNA, predict declining renal function, poor response to therapy, and adverse renal outcomes, according to work presented at the annual meeting of the Canadian Rheumatology Association.

“These proteins are not only predominantly elevated in patients with proliferative lupus nephritis, but they correlate with adverse renal outcomes when patients are followed over 24 months,” reported Laura P. Whittall-Garcia, MD, a clinical fellow in rheumatology at the University of Toronto.

Lupus nephritis is common in SLE, developing in about 50% of patients, according to Dr. Whittall-Garcia. Of these, up to 20% will not respond to standard therapies, typically resulting in end-stage renal disease. Up until now, there has been no reliable method of predicting this adverse clinical course.
 

Proteins identified in NETs

The series of studies conducted by Dr. Whittall-Garcia and coinvestigators were focused on NETs, a network of strings of DNA that typically bind pathogenic microbes to prevent infection but can participate in the pathology of immune-mediated conditions. As Dr. Whittall-Garcia explained, DNA extruded from NETs has been a source of autoantigens.

Based on earlier work, they pursued the hypothesis that high mobility group box 1 (HMGB1) and elastase, which are both NET components, mediate NETosis, the immune response that protects against microbes in healthy individuals but contributes to tissue damage in patients with immune-related disorders. The first aim of this work was to confirm that elevations of elastase-DNA and HMGB1-DNA correlate with active lupus nephritis. The second aim was to determine if levels of these proteins at the time of lupus nephritis flare predicted renal outcomes at 12 and 24 months.

To pursue the first hypothesis, 49 patients with active SLE (18 of whom had active lupus nephritis) were evaluated along with 23 patients with inactive SLE and 20 healthy controls.

Highest levels seen in proliferative nephritis

Relative to healthy controls, patients with active SLE have highly significantly increased levels of both proteins (P < .0001). And relative to those with inactive SLE, the levels of active patients were higher but fell short of statistical significance. However, when the researchers compared those with active lupus nephritis with those who had active SLE but no nephritis, both proteins were significantly higher (P < .04), and the levels in patients with proliferative relative to nonproliferative lupus nephritis were higher still (P < .009).

To pursue the second aim of the study, the researchers retrospectively evaluated 109 patients with SLE. All had active lupus nephritis, a baseline estimated glomerular filtration rate (eGFR) greater than 30 mL/min prior to the flare, and at least 2 years of follow-up. They evaluated complete response at 12 and 24 months, percent decline in eGFR, and severe renal impairment (eGFR ≤ 30 mL/min) in the context of levels of elastase and HMGB1.

With elevations in either NET remnant, the odds ratio of failing to achieve a complete response at 24 months were approximately doubled for elastase-DNA (OR, 1.96; P = .01) and for HMGB1 (OR, 2.61; P = .02). For the endpoint of severe renal impairment 24 months after a lupus nephritis flare, there was also a positive association with both elastase-DNA (OR, 1.55; P = .005) and HMBG1-DNA (OR, 1.91; P = .01).

“For every 100-unit increase in elastase-DNA complexes, there is a 4.8% decrease in eGFR,” reported Dr. Whittall-Garcia, who noted this relationship was highly statistically significant (P < .0001). For HMGB1-DNA, each 100-unit increase was associated with a 5.3% decrease in eGFR (P = .0006).
 

No other biomarkers compare for prognosis

“After adjusting for multiple variables, these protein levels at the time of the flare outperformed all conventional biomarkers, including proteinuria and complement levels,” Dr. Whittall-Garcia said.

Larger validating studies are needed, but Dr. Whittall-Garcia is optimistic that measuring these NET remnant levels will prove useful for monitoring patients at the time of the lupus nephritis flare and over time for the purposes of predicting adverse outcomes and response to therapy.

Although more work is needed, Adegbenga A. Bankole, MD, associate professor of medicine at Virginia Tech University and chief of the rheumatology division at the Carilion Clinic, both in Roanoke, agreed that this is a promising research direction. He reported that NETs have been attracting interest at several research centers for their potential in helping to understand the pathogenesis of lupus nephritis.

“It is unlikely that any one test will ever be a panacea in the diagnosis or predictor of outcomes in lupus nephritis,” Dr. Bankole said in an interview, but “given the importance of NETosis in the development of this disease, studies like this will form the basis of the multistep process through which we will improve patient care.”

With further progress in this area, Dr. Bankole predicted that these studies will lead to clinical applications.

“Dr. Whittall-Garcia and her team will help in the development of diagnostic and/or predictive algorithms that may go on to help improve survival of future patients with SLE,” he said.Dr. Whittall-Garcia and Dr. Bankole report they have no relevant financial relationships.

Larger validating studies are needed, but Dr. Whittall-Garcia is optimistic that measuring these NET remnant levels will prove useful for monitoring patients at the time of the lupus nephritis flare and over time for the purposes of predicting adverse outcomes and response to therapy.

Although more work is needed, Adegbenga A. Bankole, MD, associate professor of medicine at Virginia Tech University and chief of the rheumatology division at the Carilion Clinic, both in Roanoke, agreed that this is a promising research direction. He reported that NETs have been attracting interest at several research centers for their potential in helping to understand the pathogenesis of lupus nephritis.

“It is unlikely that any one test will ever be a panacea in the diagnosis or predictor of outcomes in lupus nephritis,” Dr. Bankole said in an interview, but “given the importance of NETosis in the development of this disease, studies like this will form the basis of the multistep process through which we will improve patient care.”

With further progress in this area, Dr. Bankole predicted that these studies will lead to clinical applications.

“Dr. Whittall-Garcia and her team will help in the development of diagnostic and/or predictive algorithms that may go on to help improve survival of future patients with SLE,” he said.Dr. Whittall-Garcia and Dr. Bankole report they have no relevant financial relationships.

Asymptomatic adults, teens, and pregnant women with no known history or symptoms of herpes infection need not undergo routine screening, according to the latest recommendation from the U.S. Preventive Services Task Force.

The 2023 recommendation reaffirms the conclusion from 2016, wrote Carol M. Mangione, MD, of the University of California, Los Angeles, and members of the task force.

“Currently, routine serologic screening for genital herpes is limited by the low predictive value of the widely available serologic screening tests and the expected high rate of false-positive results likely to occur with routine screening of asymptomatic persons in the U.S.,” the authors said.

In the recommendation, published in JAMA, the authors affirmed with moderate certainty and a grade D recommendation that the risks of routine screening for herpes simplex virus (HSV) in asymptomatic individuals outweigh the benefits.

The task force found no new evidence on the accuracy of serologic screening tests, the benefits of early detection and treatment, or on the harms of screening and treatment since the 2016 review of 17 studies in 19 publications, with data from more than 9,000 individuals.

Studies of the accuracy of serologic screening for herpes simplex virus-2 in the 2016 report mainly reflect populations with higher HSV-2 prevalence and are of limited applicability to the U.S. primary care population, the authors wrote. Evidence from the 2016 review also showed limited and inconsistent support for the early identification and treatment of HSV-2 in asymptomatic individuals, including those who were pregnant.

No new evidence has emerged since 2016 regarding harms of screening or treating genital herpes in asymptomatic individuals, the authors noted. “Based on previous evidence, the USPSTF estimated that using the widely available serologic tests for HSV-2, nearly 1 of every 2 diagnoses in the general U.S. primary care population could be false,” they said. The task force also concluded that the low accuracy of the current tests could prompt unnecessary treatment for individuals with false-positive diagnoses, as well as social and emotional harm for these individuals.

During a period of public comment from Aug. 16, 2022, to Sept. 12, 2022, individuals expressed concerns that the recommendation against routine screening showed a disinclination to take herpes seriously, and concerns that asymptomatic individuals could transmit the infection to sexual partners, the authors said. However, the estimated seroprevalence of HSV-1 and HSV-2 has declined in recent decades, and other comments supported the USPSTF’s analysis of the evidence and noted their consistency with current clinical practice.

The task force noted that research gaps remain and recognized the need to improve screening and treatment of genital herpes to prevent symptomatic episodes and transmission. Specifically, the USPSTF recommendation calls for more research to assess the accuracy of screening tests, to enroll more study participants from populations disproportionately affected by HSV, to examine the effect of behavioral counseling, and to clarify associations between HSV and pregnancy outcomes. In addition, the task force called for research to create an effective vaccine to prevent genital HSV infection and to develop a cure.
 

Targeted screening makes sense for now

“Given the frequency and severity of the range of diseases seen with HSV and the large proportion of persons who are asymptomatic, identifying carriers through type-specific serologic screening has long been considered a plausible strategy,” Mark D. Pearlman, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial.

However, accuracy of the currently available serology screening tests is low, and the adverse social and psychological effects and the impact on relationships for many asymptomatic individuals who test positive and may be incorrectly identified as infected remains a concern, said Dr. Pearlman.

Although some may be disagree about the value of routine serotesting for HSV-2 in asymptomatic individuals, other strategies can reduce the spread of infection and help those infected, he said.

Many experts continue to recommend targeted serotesting to high-risk populations, such as pregnant women whose nonpregnant partner is known to have genital or oral herpes and whose own infection status or serostatus is uncertain, said Dr. Pearlman. Other targeted strategies include screening individuals with recurrent or atypical genital symptoms and negative polymerase chain reaction assay or culture results, a clinical herpes diagnosis without laboratory confirmation, or those at increased risk because of a high number of sexual partners or a history of HIV infection, he said.

“Of note, the current CDC STI guidelines and ACOG both concur with the USPSTF that routine screening in the general population or routine screening during pregnancy are not recommended,” Dr. Pearlman said. Meanwhile, research efforts continue to help reduce the impact of HSV disease and development of a more effective testing methodology “might tip the balance in favor of routine screening” in the future, he emphasized.

The recommendations were supported by the Agency for Healthcare Research and Quality. The members of the task force received reimbursement for travel and an honorarium but had no other relevant financial conflicts to disclose. Dr. Pearlman had no financial conflicts to disclose.

Repetitive transcranial magnetic stimulation (rTMS) is associated with reduced symptom severity in patients with comorbid major depressive disorder (MDD) and substance use disorders (SUDs), new research suggests.

In a retrospective observational study, participants receiving 20-30 rTMS sessions delivered over a course of 4-6 weeks showed significant reductions in both craving and depression symptom scores.

In addition, the researchers found that the number of rTMS sessions significantly predicted the number of days of drug abstinence, even after controlling for confounders.

“For each additional TMS session, there was an additional 10 days of abstinence in the community,” principal investigator Wael Foad, MD, medical director, Erada Center for Treatment and Rehabilitation, Dubai, United Arab Emirates, told this news organization.

However, Dr. Foad noted that he would need to construct a randomized controlled trial to further explore that “interesting” finding.

The results were published in the Annals of Clinical Psychiatry.
 

Inpatient program

The researchers retrospectively analyzed medical records of men admitted to the inpatient unit at the Erada Center between June 2019 and September 2020. The vast majority were native to the UAE.

The inpatient program focuses on treating patients with SUDs and is the only dedicated addiction rehabilitation service in Dubai, the investigators noted.

They analyzed outcomes for 55 men with mild to moderate MDD who received rTMS as standard treatment.

Participants were excluded from the data analysis if they had another comorbid diagnosis from the DSM-5 other than SUD or MDD. They were also excluded if they used an illicit substance 2 weeks before the study or used certain medications, including antipsychotics, benzodiazepines, or mood stabilizers.

When patients first arrived on the unit, they were detoxed for a period of time before they began receiving rTMS sessions.

The 55 men received 20-30 high-frequency rTMS sessions over the course of 4-6 weeks in the area of the dorsolateral prefrontal cortex. Each session consisted of 3,000 pulses delivered over a period of 37.5 minutes.  Severity of depression was measured with the Clinical Global Impression–Severity Scale (CGI-S), which uses a 7-point Likert scale.

In addition, participants’ scores were tracked on the Brief Substance Craving Scale (BSCS), a self-report scale that measures craving for primary and secondary substances of abuse over a 24-hr period.

Of all participants, 47% said opiates and 35% said methamphetamine were their primary substances of abuse.
 

Significant improvement

Results showed a statistically significant improvement (P < .05) between baseline and post-rTMS treatment scores in severity of depression and drug craving, as measured by the BSCS and the CGI-S.

The researchers noted that eight participants dropped out of the study after their first rTMS session for various reasons.

Dr. Foad explained that investigators contracted with study participants to receive 20 rTMS sessions; if the sessions were not fully completed during the inpatient stay, the rTMS sessions were continued on an outpatient basis. A study clinician closely monitored patients until they finished their sessions.

For each additional rTMS session the patients completed beyond 20 sessions, there was an associated excess of 10 more days of abstinence from the primary drug in the community.

The investigators speculated that rTMS may reduce drug craving by increasing dopaminergic binding in the striatum, or by releasing dopamine in the caudate nucleus.

Study limitations cited include the lack of a control group and the fact that the study sample was limited to male inpatients, which limits generalizability of the findings to other populations.
 

Promising intervention

Commenting on the study, Colleen Ann Hanlon, PhD, noted that, from years of work using TMS for depression, “we know that more sessions of TMS during the acute treatment phase tends to lead to stronger and possibly more durable results long-term.”

Dr. Hanlon, who was not involved with the current research, formerly headed a clinical neuromodulation lab at Wake Forest University, Winston-Salem, N.C. She is now vice president of medical affairs at BrainsWay, an international health technology company specializing in Deep TMS.

She noted that Deep TMS was approved by the Food and Drug Administration for smoking cessation in 2020, “which was a tremendous win for our field at large, and requires only 15 acute sessions followed by 3 weekly sessions” of deep TMS.

“I suspect this is just the beginning of a new era in neuromodulation-based therapeutics for people struggling with drug and alcohol use disorders,” Dr. Hanlon said. 

The study behind the FDA approval for smoking approval was a large double-blind, sham-controlled multisite clinical trial where investigators used an H4 coil – a TMS coil that modulates multiple brain areas involved in addictive behaviors simultaneously.

Results from that study showed that 15 sessions of deep TMS significantly improved smoking cessation rates relative to sham (10 Hz, 120% motor threshold, H4 coil, 1,800 pulses/session).

“The difference in cigarette consumption and craving was significant as early as 2 weeks after treatment initiation,” said Dr. Hanlon. “I am looking forward to the future of this field for all people suffering from drug and alcohol use disorders.”

The study and services provided through the Erada Center were funded by the government of Dubai. The investigators reported no relevant financial relationships.

Key clinical point: Nearly half of the patients with psoriatic arthritis (PsA) treated with apremilast achieved disease activity index for psoriatic arthritis (DAPSA) low disease activity/remission at 6 or 12 months, with lower baseline disease activity being the only factor associated with the achievement of low disease activity or remission.

Major finding: Overall, 42.7% and 54.9% of patients achieved DAPSA low disease activity or remission at 6 and 12 months, respectively. Baseline DAPSA was inversely associated with the odds of achieving low disease activity or remission at 6 months (odds ratio [OR] 0.84) and 12 months (OR 0.91; both P < .01).

Exercise training is 3.5 times more likely to result in a clinically meaningful response in liver fat, compared with standard clinical care, for patients with nonalcoholic fatty liver disease (NAFLD), according to a new systematic review and meta-analysis.

An exercise dose of 750 metabolic equivalents of task (MET)–minutes per week – or 150 minutes per week of brisk walking – was required to achieve a treatment response, independently of weight loss.

“In the absence of a regulatory agency–approved drug treatment or a cure, lifestyle modification with dietary change and increased exercise is recommended for all patients with NAFLD,” first author Jonathan Stine, MD, an associate professor of medicine and public health sciences and director of the fatty liver program at the Penn State Health Milton S. Hershey Medical Center, Hershey, said in an interview.

“With that said, there are many key unanswered questions about how to best prescribe exercise as medicine to our patients with NAFLD, including whether the liver-specific benefit of exercise can be seen without any body weight loss,” Dr. Stine said. “And if found, what dose of exercise is required in order to achieve clinically meaningful benefit?” He noted that this analysis is a step toward helping to answer these questions.

The study by Dr. Stine and colleagues was published online in The American Journal of Gastroenterology.
 

Analyzing studies

Exercise training, which includes planned and structured physical activity intended to improve physical fitness, has been shown to provide multiple benefits for patients with NAFLD, the study authors wrote. The gains include improvements in liver fat, physical fitness, body composition, vascular biology, and health-related quality of life.

However, it has been unclear whether exercise training achieves a 30% or more relative reduction in liver fat, which is considered the minimal clinically important difference and is a surrogate for histologic response or improvement in liver fibrosis.

In their systematic review and meta-analysis, Dr. Stine and colleagues analyzed the evidence for MRI-measured liver reduction in response to exercise training across different doses, with a 30% or more relative reduction serving as the primary outcome. They included randomized controlled trials in adults with NAFLD who participated in exercise training programs.

The 14 studies included a total of 551 participants. The average age of the participants was 53 years, and the average body mass index was 31 kg/mg². The duration of the interventions ranged from 4 to 52 weeks and included different types of exercise, such as aerobic, high-intensity interval, resistance, and aerobic plus resistance training.

No study yielded the clinically significant weight loss required for histologic response (7%-10%). The average weight loss was about 2.8% among those who participated in exercise training.

Overall, seven studies with 152 participants had data for the 30% or more relative reduction in MRI-measured liver fat. The pooled rate was 34% for exercise training and 13% for the control condition.

In general, those who participated in exercise training were 3.5 times more likely to achieve a 30% or more relative reduction in MRI-measured liver fat than those in the control condition.

Among all participants, the mean change in absolute liver fat was –6.7% for the 338 participants enrolled in exercise training, compared with –0.8% for the 213 participants under the control condition. The pooled mean difference in absolute change in MRI-measured liver fat for exercise training versus the control was –5.8%.

For relative change in MRI-measured liver fat, researchers analyzed nine studies with 195 participants – 118 participants in exercise training, and 77 control participants. The mean relative change was –24.1% among the exercise training group and 7.3% among the control group. The pooled mean difference in relative change for exercise training versus the control was –26.4%.

For all 14 studies, an exercise dose of 750 or more MET-minutes per week resulted in a significant treatment response. This equates to 150 minutes per week of moderate-intensity exercise, such as brisk walking, or 75 minutes per week of vigorous-intensity exercise, such as jogging or cycling.

Among participants who had 750 MET-minutes per week, there was a –8% absolute and –28.9% relative mean difference in MRI-measured liver fat, compared with –4.1% and –22.8%, respectively, among those who had fewer than 750 MET-minutes per week.

An exercise dose of 750 or more MET-minutes per week led to a 30% or more relative reduction in MRI-measured liver fat in 39.3% of participants, compared with 25.7% who had fewer than that threshold.

The treatment response was independent of clinically significant body weight loss of more than 5%.

“Prior to our study, it was felt that body weight loss of at least 5% was required in order to significantly improve liver histology,” Dr. Stine said. “Our findings challenge this thought in that exercise training achieved rates of clinically significant liver fat reduction.”
 

Ongoing research

Dr. Stine and colleagues are continuing their research and are directly comparing exercise doses of 750 MET-minutes per week and 1,000 MET-minutes per week to standard clinical care in adults with biopsy-proven nonalcoholic steatohepatitis, or the progressive type of NAFLD.

“Importantly, this new study we’re undertaking is designed to mimic a real-world setting in which people’s daily schedules are highly variable,” he said. “Our experienced team of exercise professionals may vary frequency and time of exercise in a week so long as our study participant achieves the prescribed dose of exercise.”

Currently, leading professional societies have not reached consensus regarding the optimal physical activity program for patients with NAFLD, the study authors wrote. However, most clinical guidelines support at least 150 minutes per week of moderate-intensity aerobic activity.

Although more head-to-head clinical trials are needed, exercise training appears to reduce liver fat and provides other benefits, such as cardiorespiratory fitness, body composition changes, and improvements in vascular biology, they wrote.

“The important piece here is that this review shows that there does not have to be weight loss for improvements in fatty liver,” Jill Kanaley, PhD, a professor of nutrition and exercise physiology at University of Missouri–Columbia, said in an interview.

Dr. Kanaley, who wasn’t involved with this study, has researched exercise training among patients with NAFLD. She and her colleagues have found that moderate-and high-intensity exercise can decrease intrahepatic lipid content and NAFLD risk factors, independently of abdominal fat or body mass reductions.

“So often, people get frustrated with exercise if they do not see weight loss,” she said. “But in this case, there seems to be benefits of the exercise, even without weight loss.”

The study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases. The authors have received research funding and have had consultant roles with numerous pharmaceutical companies. Dr. Kanaley reported no relevant financial relationships.

Key clinical point: Preventive monitoring for cardiovascular risk is suggested in tofacitinib-treated patients with psoriatic arthritis (PsA) as higher atherosclerotic cardiovascular disease (ASCVD) risk appears to be associated with a higher incidence of major cardiovascular events (MACE) and malignancies.

Major finding: The risk for MACE appeared to be higher among patients with PsA and high vs low 10-year ASCVD risk (incidence rate [IR] 1.37 [95% CI 0.03-7.63] vs 0.08 [95% CI 0.0-0.42]), with the incidence of malignancies being the highest in patients with PsA and an intermediate 10-year ASCVD risk (IR 2.56, 95% CI 1.11-5.05).

Study details: Findings are from a post hoc analysis of 10 clinical trials including patients with PsA (n = 783) and psoriasis (n = 3663) who received tofacitinib.

Disclosures: This study was sponsored by Pfizer. Some authors declared receiving speaker fees or grant or research support or serving as consultants for various sources, including Pfizer.

Key clinical point: Signatures of circulating microRNA in patients with psoriatic arthritis (PsA) and patients with psoriasis were significantly different from those in control individuals, with some even being differentially regulated between PsA and psoriasis.

Major finding: Overall, 9 microRNA best differentiated patients with PsA and psoriasis from control individuals (area under the curve [AUC] ≥0.70; all P < .05) and 4 microRNA best differentiated patients with PsA from patients with psoriasis (all P < .05). A combination of 4 microRNA (miR-19b-3p, miR-21-5p, miR-92a-3p, and let-7b-5p) vs miR-92a-3p alone could better differentiate between patients with PsA and psoriasis (AUC 0.92 vs 0.82).

Study details: This cross-sectional study included 51 patients with PsA, 40 patients with psoriasis, and 50 control individuals.

Disclosures: This study did not receive any specific funding. Two authors declared being employees or shareholders of TAmiRNA GmbH or holding intellectual property for the diagnostic use of microRNA in bone diseases.

A combination of 4 microRNA (miR-19b-3p, miR-21-5p, miR-92a-3p, and let-7b-5p) vs miR-92a-3p alone could better differentiate between patients with PsA and psoriasis (AUC 0.92 vs 0.82).

Study details: This cross-sectional study included 51 patients with PsA, 40 patients with psoriasis, and 50 control individuals.

Disclosures: This study did not receive any specific funding. Two authors declared being employees or shareholders of TAmiRNA GmbH or holding intellectual property for the diagnostic use of microRNA in bone diseases.
