Increased levels of the cytokine resistin were significantly associated with an increased risk for death in adults with pulmonary arterial hypertension (PAH), based on data from more than 1000 individuals.

Resistin, a cytokine expressed in adipocytes, has been associated with poor clinical outcomes in heart failure and cardiovascular disease, Li Gao, MD, of Johns Hopkins University, Baltimore, Maryland, and colleagues wrote. While mouse studies have shown that human resistin drives pulmonary vascular remodeling and the development of PAH, the role of resistin as a biomarker for PAH remains unclear.

In a study published in Respiratory Research, the researchers reviewed biospecimens and clinical and genetic data from 1121 adults with PAH, 808 with idiopathic PAH (IPAH), and 313 with scleroderma-associated PAH (SSc-PAH). They examined the associations between serum resistin levels and PAH outcomes in multivariate regression models, using machine-learning algorithms to develop models to predict mortality.

Resistin levels were significantly higher in all patients with PAH and patients with the two subtypes than in control participants (all P < .0001). Resistin was also associated with significant discriminative properties, with area under the curve (AUC) measures of 0.84, 0.82, and 0.91 for PAH overall, IPAH, and SSc-PAH, respectively.

Elevated resistin levels (defined as > 4.54 ng/mL) were significantly associated with an increased risk for death (hazard ratio, 2.6; P < .0087) as well as with older age and shorter distance on the 6-minute walk test (P = .001 for both) and reduced cardiac capacity based on the New York Heart Association functional class (P < .014).

Survival models derived from machine learning confirmed the prognostic value of resistin for mortality in PAH as seen in the random forest model, with an AUC of 0.70. “When we used the AUC values of the ROC curve as criteria to evaluate how well resistin levels discerned the presence of PAH, all three tests had excellent discriminative ability (AUCs were 0.84, 0.82, and 0.91 for all PAH, IPAH, and SSc-PAH, respectively),” the researchers wrote.

The researchers also evaluated three RETN genetic variants (rs7408174, rs3219175, and rs3745367) for a specific association with serum resistin levels and measures of PAH severity. Resistin levels were highest among individuals who were carriers of either the rs3219175 or rs3745367 mutation, the researchers noted.

The findings were limited by several factors, including missing data on the 6-minute walk test from several centers, which led to the elimination of that item from the survival analysis. Other limitations included the inability to control for PAH therapy at the time of assessment and the collection of serum at a different time from other clinical variables.

However, “our study provides evidence to support the use of circulating biomarkers as objective and accessible tools for noninvasive PAH risk stratification,” the researchers said. Additional research is needed to strengthen the association, but the findings suggest that resistin represents a novel biomarker for PAH prognostication and risk stratification and may have implications for the development of new treatments.
 

Biomarker Research Expands Diagnosis and Treatment Horizons

“It is a dynamic time in PAH research and clinical management, given the recent approval and use of the BMP/TGF beta balancing agent sotatercept (Winrevair) as an effective agent to target the molecular origins of this disease,” Stephen Chan, MD, professor of medicine and director of the Vascular Medicine Institute at the University of Pittsburgh, Pittsburgh, Pennsylvania, said in an interview.

The growing number of medications that can be used to treat patients with PAH will likely be more effective if patients are identified and treated early, said Dr. Chan, who was not involved in the study.

However, the time to diagnosis for patients with PAH is still more than 3 years from the start of symptoms, he said. Factors contributing to the delay include the requirement of an invasive cardiac catheterization procedure to make the final diagnosis, the status of PAH as a borderline orphan disease, and the often nonspecific nature of the initial symptoms of PAH.

Consequently, “there is an unmet need to develop effective and preferably noninvasive tools to aid in early diagnosis of PAH,” Dr. Chan added.

The power of the study is in the number of patients included, as much of previous PAH research has involved small studies of patients that could not be replicated or did not generalize to the larger patient population, Dr. Chan said.

The use of the PAH Biobank allows researchers to access a larger population of patients with PAH. “With that in mind, it is not surprising that some markers would emerge as potentially powerful and clinically meaningful,” he said.

“Currently, we do not have a reliable blood-based biomarker that we use in clinical PAH practice, although there are emerging studies that suggest other markers such as metabolites, RNA molecules, and proteins that may serve in the same capacity. If these studies turn out to be reproducible, generalizable, and specific to PAH in larger populations, measuring resistin could be helpful in making early diagnosis, particularly in areas that do not have invasive catheterization facilities (and globally) and for nonspecialists who are puzzled about the nonspecificity of initial symptoms of PAH,” Dr. Chan said.

Resistin could also be incorporated into existing risk stratification scores, such as the REVEAL risk score, that are already used in PAH clinical practice as guidance for when and how to use currently approved medications, he added.

Limitations of the study included the focus only on resistin alone, not in combination with other molecules that might perform better. Also, no independent validation cohort was used, he noted. “While PAH Biobank certainly offered larger numbers than we typically see, we would have to see validation in large independent cohorts for us to be convinced that measurements of resistin should be used in clinical practice.”

Resistin is not specific to PAH, which makes interpretation of the results more complicated, said Dr. Chan. “In this study, the authors used a smaller healthy control cohort of 50 patients as a comparison to their PAH cohort. However, they did not compare their PAH cohort with other cohorts that represent these other ‘resistin-relevant diseases’ and thus do not know whether they can distinguish PAH from any of these other diseases based on simply the resistin levels.” The frequency of comorbidities in patients with PAH, such as obesity, other inflammatory diseases, and cardiovascular disease, could confound the resistin levels.

The study was supported by the National Institutes of Health. Neither the researchers nor Dr. Chan had financial conflicts to disclose.

Individuals with preexisting sleep disturbances including obstructive sleep apnea (OSA), insomnia, and abnormal sleep duration showed significantly increased vulnerability to COVID-19, as well as an increased risk for hospitalization, mortality, and long COVID, according to new data from more than 8 million individuals.

Sleep disturbances, though common in the general population, are generally overlooked as a risk factor for COVID-19, wrote Jiawei Zhou, MD, of The First Hospital of China Medical University, Shenyang, China, and colleagues. Most previous research has focused on the impact of COVID-19 on sleep disturbances, not the impact of sleep disturbances on COVID-19, and most studies on the latter topic have focused only on OSA, the researchers wrote.

In a meta-analysis published in eClinicalMedicine, part of The Lancet Discovery Science, the researchers identified 48 observational studies published between October 27, 2023, and May 8, 2024, that involved COVID-19 and sleep disturbances including OSA, insomnia, abnormal sleep duration, and night shift work, among others. The study population included 8,664,026 adults.

The primary outcomes were COVID-19 susceptibility, hospitalization, mortality, and long COVID. Overall, the presence of preexisting sleep disturbances was associated with a significantly increased risk for each of these outcomes, with odds ratios (ORs) of 1.12, 1.25, 1.45, and 1.36, respectively.

In subgroup analyses, the association between preexisting sleep disturbances and greater susceptibility and hospitalization was higher in younger adults (younger than 60 years) than in older adults (aged 60 years and older), but the risk for death was lower in younger adults with sleep disturbances than in older adults with sleep disturbances (OR, 1.22 vs OR, 2.07, respectively). Men with sleep disturbances had a higher risk for COVID-19 mortality than women with sleep disturbances.

Preexisting sleep disturbances overall were significantly associated with long COVID and more so in a subgroup analysis of patients whose definition of long COVID was symptoms lasting 3 or more months vs those lasting 1 month (P = .029).

When the researchers broke down associations with COVID-19 outcomes and specific sleep disturbances, they found significant associations between OSA and all four primary outcomes. Abnormal sleep duration was associated with an increased risk for COVID-19 susceptibility, hospitalization, and long COVID. Night shift work was associated with an increased risk for COVID-19 susceptibility and hospitalization, and insomnia was associated with an increased risk for long COVID.

Although the exact mechanism behind the associations between preexisting sleep disturbances and COVID-19 outcomes is uncertain, persistent sleep deprivation could set the stage in various ways, including the promotion of elevated C-reactive protein and interleukin-6 levels, the researchers wrote.

“Overall, the compromised innate and adaptive immune functions combined with a persistent inflammatory state may explain the higher risk of susceptibility, severity, and longer recovery time observed in patients with sleep disturbances. Fortunately, early intervention for sleep disturbances could attenuate the adverse effects of COVID-19,” they noted in their discussion.

The findings were limited by several factors including the observational nature of the studies and the heterogeneity of outcomes, the researchers wrote. Looking ahead, randomized, controlled trials are needed to examine the effect of interventions for sleep disturbances in the prevention and course of COVID-19, they said.

However, the study is the first known to examine multiple types of sleep disturbances and their possible influences on the full clinical course of COVID-19 and support the need for early evaluation and intervention for individuals with sleep disturbances to reduce short-term and long-term effects of the disease, the researchers concluded.
 

Findings Reflect the Need to Address Sleep Issues Early

Although the results of the current study were not surprising, “it is always worth doing meta-analyses to see if there is a potential signal in the published data to suggest a need for a new study,” Arun Chatterjee, MD, professor of pulmonary, critical care, allergy, and immunologic diseases at Wake Forest University, Winston-Salem, North Carolina, said in an interview.

“Lack of sleep, whether acute active deprivation (zero sleep for one night) or subacute/chronic sleep debt, such as only 5 hours per night, has been demonstrated to affect lymphocyte proliferation, reduce immune globulin levels, increase inflammatory markers, shorten telomeres, and affect the immune system in various ways,” said Dr. Chatterjee, who was not involved in the meta-analysis.

The clinical takeaway from the current meta-analysis is that adequate sleep is important for various reasons, Dr. Chatterjee said. “Sleep disruption affects health across a spectrum of systems; adding an annual sleep wellness and screening event to healthcare visits is probably worth the investment,” he noted.

Much more is needed in the way of additional research, Dr. Chatterjee told this news organization. Notably, studies are needed to examine what sleep disruption does to immune status, as well as all other physiologic and mental health systems, he said.

The study was supported by the National Natural Science Foundation of China and the Key Laboratory of Respiratory Diseases of Liaoning Province. The researchers had no financial conflicts to disclose. Chatterjee had no financial conflicts to disclose.

Preconception and prenatal care are more complicated in women with chronic health conditions but attention to disease management and promoting the adoption of a healthier lifestyle can improve outcomes for mothers and infants, according to a growing body of research.

The latest version of the International Federation of Gynecology and Obstetrics Preconception Checklist, published in the International Journal of Gynecology & Obstetrics, highlights preexisting chronic medical conditions such as diabetes, lupus, and obesity as key factors to address in preconception care through disease management. A growing number of studies support the impact of these strategies on short- and long-term outcomes for mothers and babies, according to the authors.
 

Meet Glycemic Control Goals Prior to Pregnancy

“Women with diabetes can have healthy pregnancies but need to prepare for pregnancy in advance,” Ellen W. Seely, MD, professor of medicine at Harvard Medical School and director of clinical research in the endocrinology, diabetes, and hypertension division of Brigham and Women’s Hospital, Boston, said in an interview.

“If glucose levels are running high in the first trimester, this is associated with an increased risk of birth defects, some of which are very serious,” said Dr. Seely. Getting glucose levels under control reduces the risk of birth defects in women with diabetes close to that of the general population, she said.

The American Diabetes Association has set a goal for women to attain an HbA1c of less than 6.5% before conception, Dr. Seely said. “In addition, some women with diabetes may be on medications that should be changed to another class prior to pregnancy,” she noted. Women with type 1 or type 2 diabetes often have hypertension as well, but ACE inhibitors are associated with an increased risk of fetal renal damage that can result in neonatal death; therefore, these medications should be stopped prior to pregnancy, Dr. Seely emphasized.

“If a woman with type 2 diabetes is on medications other than insulin, recommendations from the ADA are to change to insulin prior to pregnancy, since we have the most data on the safety profile of insulin use in pregnancy,” she said.

To help women with diabetes improve glycemic control prior to pregnancy, Dr. Seely recommends home glucose monitoring, with checks of glucose four times a day, fasting, and 2 hours after each meal, and adjustment of insulin accordingly.

A healthy diet and physical activity remain important components of glycemic control as well. A barrier to proper preconception and prenatal care for women with diabetes is not knowing that a pregnancy should be planned, Dr. Seely said. Discussions about pregnancy should start at puberty for women with diabetes, according to the ADA, and the topic should be raised yearly so women can optimize their health and adjust medications prior to conception.

Although studies of drugs have been done to inform preconception care for women with diabetes, research is lacking in several areas, notably the safety of GLP-1 agonists in pregnancy, said Dr. Seely. “This class of drug is commonly used in type 2 diabetes and the current recommendation is to stop these agents 2 months prior to conception,” she said.
 

Conceive in Times of Lupus Remission

Advance planning also is important for a healthy pregnancy in women with systemic lupus erythematosus (SLE), Sayna Norouzi, MD, director of the glomerular disease clinic and polycystic kidney disease clinic of Loma Linda University Medical Center, California, said in an interview.

“Lupus mostly affects women of childbearing age and can create many challenges during pregnancy,” said Dr. Norouzi, the corresponding author of a recent review on managing lupus nephritis during pregnancy.

“Women with lupus face an increased risk of pregnancy complications such as preeclampsia, problems with fetal growth, stillbirth, and premature birth, and these risks increase based on factors such as disease activity, certain antibodies in the body, and other baseline existing conditions such as high blood pressure,” she said.

“It can be difficult to distinguish between a lupus flare and pregnancy-related issues, so proper management is important,” she noted. The Predictors of Pregnancy Outcome: Biomarkers in Antiphospholipid Syndrome and Systemic Lupus Erythematosus (PROMISSE) study findings indicated a lupus nephritis relapse rate of 7.8% of patients in complete remission and 21% of those in partial remission during pregnancy, said Dr. Norouzi. “Current evidence has shown that SLE patients without lupus nephritis flare in the preconception period have a small risk of relapse during pregnancy,” she said.

Before and during pregnancy, women with lupus should work with their treating physicians to adjust medications for safety, watch for signs of flare, and aim to conceive during a period of lupus remission.

Preconception care for women with lupus nephritis involves a careful review of the medications used to control the disease and protect the kidneys and other organs, said Dr. Norouzi.

“Adjustments,” she said, “should be personalized, taking into account the mother’s health and the safety of the baby. Managing the disease actively during pregnancy may require changes to the treatment plan while minimizing risks,” she noted. However, changing medications can cause challenges for patients, as medications that are safer for pregnancy may lead to new symptoms and side effects, and patients will need to work closely with their healthcare providers to overcome new issues that arise, she added.

Preconception lifestyle changes such as increasing exercise and adopting a healthier diet can help with blood pressure control for kidney disease patients, said Dr. Norouzi.

In the review article, Dr. Norouzi and colleagues noted that preconception counseling for patients with lupus should address common comorbidities such as hypertension, diabetes, obesity, and dyslipidemia, and the risk for immediate and long-term cardiovascular complications.
 

Benefits of Preconception Obesity Care Extend to Infants

Current guidelines from the American College of Obstetricians and Gynecologists and the Institute of Medicine advise lifestyle interventions to reduce excessive weight gain during pregnancy and reduce the risk of inflammation, oxidative stress, insulin resistance, and lipotoxicity that can promote complications in the mother and fetus during pregnancy.

In addition, a growing number of studies suggest that women with obesity who make healthy lifestyle changes prior to conception can reduce obesity-associated risks to their infants.

Adults born to women with obesity are at increased risk of cardiovascular disease and early signs of heart remodeling are identifiable in newborns, Samuel J. Burden, PhD, a research associate in the department of women and children’s health, Kings’ College, London, said in an interview. “It is therefore important to investigate whether intervening either before or during pregnancy by promoting a healthy lifestyle can reduce this adverse impact on the heart and blood vessels,” he said.

In a recent study published in the International Journal of Obesity, Dr. Burden and colleagues examined data from eight studies based on data from five randomized, controlled trials including children of mothers with obesity who engaged in healthy lifestyle interventions of improved diet and increased physical activity prior to and during pregnancy. The study population included children ranging in age from less than 2 months to 3-7 years.

Lifestyle interventions for mothers both before conception and during pregnancy were associated with significant changes in cardiac remodeling in the children, notably reduced interventricular septal wall thickness. Additionally, five studies of cardiac systolic function and three studies of diastolic function showed improvement in blood pressure in children of mothers who took part in the interventions.

Dr. Burden acknowledged that lifestyle changes in women with obesity before conception and during pregnancy can be challenging, but should be encouraged. “During pregnancy, it may also seem unnatural to increase daily physical activity or change the way you are eating.” He emphasized that patients should consult their physicians and follow an established program. More randomized, controlled trials are needed from the preconception period to examine whether the health benefits are greater if the intervention begins prior to pregnancy, said Dr. Burden. However, “the current findings indeed indicate that women with obesity who lead a healthy lifestyle before and during their pregnancy can reduce the degree of unhealthy heart remodeling in their children,” he said.

Dr. Seely, Dr. Norouzi, and Dr. Burden had no financial conflicts to disclose.

Preconception and prenatal care are more complicated in women with chronic health conditions but attention to disease management and promoting the adoption of a healthier lifestyle can improve outcomes for mothers and infants, according to a growing body of research.

The latest version of the International Federation of Gynecology and Obstetrics Preconception Checklist, published in the International Journal of Gynecology & Obstetrics, highlights preexisting chronic medical conditions such as diabetes, lupus, and obesity as key factors to address in preconception care through disease management. A growing number of studies support the impact of these strategies on short- and long-term outcomes for mothers and babies, according to the authors.

The recent Food and Drug Administration (FDA) approval of ensifentrine marks the first new treatment for patients with persistent chronic obstructive pulmonary disease (COPD) in more than a decade, according to manufacturer Verona Pharma.

Ensifentrine offers a new medication and a new delivery method, according to a company press release. Ensifentrine is the first-in-class selective dual inhibitor of both phosphodiesterase 3 (PDE 3) and PDE 4, combining both bronchodilator and nonsteroidal anti-inflammatory effects in a single molecule. The drug is delivered through a standard jet nebulizer.
 

Disease Management Made Easier

Although currently approved therapies for COPD, such as bronchodilators and inhaled corticosteroids (ICS), have benefited many patients, additional treatment options are still needed to help those who remain symptomatic and suffer from frequent exacerbations, said Diego J. Maselli, MD, of the University of Texas Health Science Center, San Antonio.

“Ensifentrine is a new class of medication that inhibits both PDE 3 and PDE 4; this results in both bronchodilation and suppression of the inflammatory response in COPD,” said Dr. Maselli, who was not involved in studies of ensifentrine.

“Large phase III, double-blind, randomized, placebo-controlled studies have demonstrated that ensifentrine improved lung function and reduced the risk of exacerbations in patients with symptomatic moderate to severe COPD,” he said. The study participants were on no long-acting maintenance therapy, or they were receiving long-acting beta agonist (LABA) or long-acting muscarinic antagonist (LAMA) with or without inhaled corticosteroids, he noted.

The FDA approval was supported by data from the phase 3 ENHANCE 1 and 2 trials, which included 760 and 789 adults aged 40-80 years with moderate to severe symptomatic COPD, respectively. Participants were randomized to 3 mg ensifentrine delivered via nebulizer or a placebo twice daily.

In the studies, ensifentrine significantly improved lung function based on the primary outcome of average forced expiratory volume per second within 0-12 hours of administration compared with placebo in both studies. In ENHANCE 1, ensifentrine significantly improved symptoms and quality of life compared with placebo at 24 weeks. The ENHANCE 2 results showed similar trends in favor of ensifentrine, although the differences were not significant at 24 weeks. However, the effects of ensifentrine vs placebo were consistent overall across all symptom and quality of life endpoints at all assessments during the study period, the researchers wrote.

In addition, the inhaled drug was well tolerated, with similar proportions of ensifentrine and placebo patients reporting treatment-emergent adverse events (38.4% and 36.4%, respectively, in ENHANCE 1 and 35.3% and 35.4%, respectively, in ENHANCE 2). The most common treatment-emergent adverse events were nasopharyngitis, hypertension, and back pain, reported in < 3% of the ensifentrine group.

The safety profile of ensifentrine is a plus for patients, said Dr. Maselli. “Ensifentrine was well tolerated in these studies, and the side effect profile was similar to placebo,” he said. The “ensifentrine is delivered via nebulizer and dosed every 12 hours. Some patients may still prefer the use of inhalers, while others may feel more comfortable with this mode of delivery,” he said. 

In clinical practice, “ensifentrine is a welcome addition to the current armamentarium of therapies for COPD as an option for patients who are symptomatic or who have frequent exacerbations,” Dr. Maselli emphasized.

Looking ahead, more studies are needed to evaluate ensifentrine in broader populations of COPD patients, Dr. Maselli said. For example, ensifentrine could be used as an add-on therapy for patients receiving triple therapy (ICS/LABA/LAMA) and for patients with other obstructive inflammatory diseases such as asthma, bronchiectasis, and cystic fibrosis, he noted.

Dr. Maselli disclosed serving as a consultant for GlaxoSmithKline, AstraZeneca, Amgen, and Sanofi/Regeneron; he also serves on the Editorial Board of CHEST Physician.

Philips Respironics Inc. has issued updated instructions for the use of its OmniLab Advanced+ (OLA+) Ventilator because of its demonstrated failure in the ventilator inoperative alarm that can cause an interruption or loss of therapy, according to a recall statement from the US Food and Drug Administration (FDA).

The OLA+ Ventilator is designed for use by individuals with obstructive sleep apnea, breathing problems, and mixed apnea and is approved for children aged 7 years and older, as well as adults.

The recall does not involve removal of the devices from where they are used or sold but does update the instructions for use, and its use without following the updated instructions could result in serious injury or death, according to the statement.

Following an alarm failure, the device may fail in one of two ways: By entering a ventilator inoperative state after three reboots within 24 hours (with no therapy and audible and visual alarms present) or by entering a ventilator inoperative state without rebooting first.

According to the statement, the alarm issue may be corrected with a software patch, available from Philips, or the company will offer a replacement device for patients until the affected devices are repaired. The statement updates an April 1, 2024, urgent recall from Philips urging the immediate removal of a patient from an OLA+ Ventilator and connecting them to alternative ventilation if possible if the ventilator’s inoperative alarm occurs.

The device failures may cause interruption or loss of therapy with effects including anxiety, confusion/disorientation, changes in respiratory rate, dyspnea, tachycardia, respiratory failure, and even death in especially vulnerable individuals. One death and 15 injuries have been reported as a result of the alarm failure, according to the FDA.

Children with asthma who were insured by Medicaid were significantly less likely to receive specialist care over a 1-year period than children with private insurance, based on claims data from nearly 200,000 children.

Primary care clinicians successfully manage many children with asthma, but data on specialist care according to insurance coverage are lacking, wrote Kimberley H. Geissler, PhD, of the University of Massachusetts Chan Medical School–Baystate, Springfield, Massachusetts, and colleagues.

Despite many interventions over time, “low-income children insured by Medicaid, many of whom are from minoritized racial and ethnic groups, continue to have worse outcomes and higher rates of poorly controlled asthma than children who are privately insured,” Dr. Geissler said in an interview.

“Because differences in whether a child sees an asthma specialist could contribute to these disparities, better understanding specialist use among both groups of kids may help inform potential solutions,” she said.

In a study published in JAMA Network Open, the researchers identified children with asthma aged 2-17 years using data from the Massachusetts All-Payer Claims Database for the years 2015-2020. The study population included 198,101 children and 432,455 child-year observations from children with asthma during a year when they met at least one of three criteria with any asthma diagnosis: One or more hospital visits, two or more outpatient visits, or at least one outpatient visit and at least one asthma medication.
 

Outpatient Visit Outcome

The primary outcome of asthma specialist care was defined as at least one outpatient visit with any asthma diagnosis to a clinician with a code of allergy and immunology, pulmonology, or otolaryngology.

A total of 66.2% of the child-year observations involved Medicaid and 33.8% involved private insurance. Approximately 15% of the children received asthma specialist care. However, nearly twice as many children with private insurance received asthma specialty care compared with those with Medicaid (20.6% vs 11.9%). In a full logistic regression analysis, children with Medicaid insurance were 55% less likely to receive asthma specialist treatment than children with private insurance.

Allergy and immunology was the most common specialty used, and the child-years for this specialty among children with Medicaid were less than half of those among children with private insurance (7.1% vs 15.9%).

Rates of persistent asthma were 20.0% and 16.9% in children with Medicaid and private insurance, respectively. Overall, children with persistent asthma were nearly four times as likely to receive asthma specialist care (adjusted odds ratio, 3.96). However, the difference in odds of receiving specialty care based on insurance type in favor of private insurance was greater among children with persistent asthma than among those without persistent asthma (−24.0 percentage points vs −20.8 percentage points).

The researchers found a similar pattern of difference in asthma specialty care in a sensitivity analysis limiting the results to child-year observations with at least one outpatient visit with any asthma diagnosis in a calendar year, although they also found a slight narrowing of the difference between the groups over time.

“Contrary to expectations, disparities in specialist care by insurance type were even more striking in children with persistent asthma,” the researchers wrote in their discussion. Notably, the growth of specialty drugs such as biologics for moderate to severe asthma are mainly prescribed by specialists, and ensuring access to specialists for children with Medicaid may reduce disparities in asthma control for those with severe or poorly controlled disease, they added.

The study findings were limited by several factors including the use only of data from Massachusetts, which may not generalize to other states, and the use of completed specialist visits without data on referrals, the researchers noted. Other limitations included a lack of data on asthma symptom frequency or control and on the setting in which an asthma diagnosis was made.

However, the results suggest a need for more attention to disparities in asthma care by insurance type, and more research is needed to determine whether these disparities persist in subsets of children with asthma, such as those with allergies or chronic medical conditions, they concluded.
 

Takeaways and Next Steps

“Perhaps unsurprisingly, children with private insurance were more likely to receive asthma specialist care than children with Medicaid,” Dr. Geissler told this news organization. The researchers expected a smaller gap between insurance types among children with persistent asthma, a marker for asthma severity, she said. However, “we found that the gap between those with Medicaid and those with private insurance is actually larger” for children with persistent asthma, she added.

As improved treatments for hard-to-control asthma become more available, pediatricians and primary care clinicians should follow the latest clinical guidelines for referring children to specialists for asthma care, said Dr. Geissler.

“Additionally, asthma specialists should ensure that their practices are accessible to children with Medicaid, as these families may face higher barriers to care; for example, transportation needs or scheduling challenges,” she said. Other strategies to overcome barriers to care might include electronic consultations with specialists or primary care–oriented interdisciplinary asthma clinics, which may be useful for all children with asthma but may particularly benefit those insured by Medicaid, she noted.

“Based on data limitations, we could not examine why we observed such big differences in specialist use by insurance type; for example, whether pediatricians were referring to specialists less for Medicaid-insured kids, or whether kids with Medicaid were less likely to see a specialist after a referral was made,” Dr. Geissler said. More research is needed to examine not only these factors but also the appropriateness of specialty care based on clinical guidelines to ensure high-quality evidence-based care for children with asthma who are insured by Medicaid, she said.
 

Improve Access and Expand Analysis

Asthma is a chronic and prevalent disease and requires a comprehensive approach that sometimes calls for specialist care, Anne Coates, MD, a pediatric pulmonologist in Portland, Maine, said in an interview.

Dr. Coates said she was surprised by the results of the current study but commended the authors for highlighting the limitations of the study, which illustrate areas for additional research. Notably, “the authors couldn’t observe referrals to specialists from primary care physicians; they used completed visits as a proxy,” Dr. Coates said.

More studies are needed to assess the completion of referral visits regardless of children’s insurance in order to better understand and address the barriers to specialty care, she added.

The current study is important because of the extent of asthma coupled with the significant number of children across the United States who are insured by Medicaid, especially underserved populations, she said.

“The burden of asthma differentially affects people of color who are living in lower resourced areas, and it is important in further research to understanding the barriers to helping people get the care they need,” Dr. Coates told this news organization. Some alternatives might include telehealth visits or even a hybrid visit to a primary care provider (PCP) who has high-speed internet, and the specialist could then conduct a telehealth visit from the PCP’s office, with the PCP acting as on-site eyes and ears, said Dr. Coates, who has used this strategy in her practice in Maine, where many patients live far from specialist care.

The study was supported by the National Heart, Lung, and Blood Institute and the University of Massachusetts Center for Clinical and Translational Science-Biostatistics, Epidemiology & Research Design Component. Dr. Geissler and Dr. Coates had no financial conflicts to disclose.

Analysis of finger sweat detected isoniazid in adults with tuberculosis (TB) for ≤ 6 hours after administration, based on data from a new pilot study.

Risk factors for TB treatment failure include poor medication compliance and insufficient exposure to medications, but measurement of drugs in samples of blood, saliva, or sweat can help assess adherence and inform dose adjustments, Katherine Longman, a PhD student at the University of Surrey, Guildford, England, and colleagues wrote.

Although TB is treatable, “it is well known that insufficient drug dosing leads to treatment failure and drug resistance, and so ensuring that patients have sufficient drug exposure is important,” said corresponding author Melanie J. Bailey, PhD, also of the University of Surrey.

“This can be carried out using blood, but blood is painful to collect and difficult to transport. Finger sweat offers a completely noninvasive way to sample patients,” but its use to determine medication adherence has not been examined, she said.

In a pilot study published in the International Journal of Antimicrobial Agents, the researchers reviewed data from 10 adults with TB who provided finger sweat, blood, and saliva samples at several time points ≤ 6 hours after receiving a controlled dose of isoniazid (median of 300 mg daily). They used liquid chromatography–mass spectrometry to examine the samples.

Overall, “isoniazid and acetyl isoniazid were detected in at least one finger sweat sample from all patients,” with detection rates of 96% and 77%, respectively, the researchers wrote. Given the short half-life of isoniazid, they used a window of 1-6 hours after administration. Isoniazid was consistently detected between 1 and 6 hours after administration, while acetyl isoniazid had a noticeably higher detection rate at 6 hours.

The researchers also examined creatinine to account for variability in volume of sweat samples, and found that finger sweat was significantly correlated to isoniazid concentration. The maximum isoniazid to creatinine ratio in finger sweat occurred mainly in the first hour after drug administration, and the activity of isoniazid in finger sweat over time reflected isoniazid concentration in serum more closely after normalization to creatinine, they said. The Pearson’s correlation coefficient (r) was 0.98 (P < .001; one-tailed), with normalization to creatinine, compared with r = 0.52 without normalization (P = .051).

The study findings were limited by several factors including the lack of knowledge of the last drug dose and lack of confirmation testing with an established method of analysis, the researchers noted. However, the results support the potential of the finger sweat test as a screening tool to indicate patients’ nonadherence or to identify patients at risk of low medication exposure.

“We were surprised that we were able to detect the drug in so many patient samples because the sample volume is so low, and so detection is challenging,” said Dr. Bailey. “We were also surprised that fingerprint and drug levels correlated so well after normalizing to creatinine. This is exciting as it unlocks the possibility to test drug levels, as well as providing a yes/no test.”

In practice, the finger sweat technique could reduce the burden on clinics by offering a completely noninvasive way to test a patient’s medication adherence. Looking ahead, more research is needed to explore whether creatinine normalization is widely applicable, such as whether it works for patients with abnormal kidney function, she added.
 

Noninvasive Option May Mitigate Treatment Challenges

The current study presents a strategy that might address current limitations in TB management, said Krishna Thavarajah, MD, a pulmonologist and director of the interstitial lung disease program at Henry Ford Hospital, Detroit, Michigan, in an interview.

Both self-administered treatment and directly observed therapy (DOT) for TB therapy have limitations, including adherence as low as 50% for TB regimens, she said. In addition, “DOT availability and efficacy can be limited by cost, personnel availability from an administration perspective, and by distrust of those being treated.”

In the current study, “I was struck by the correlation between the sweat and serum values of [isoniazid] and by the level of sophistication of noninvasive testing, being able to normalize for creatinine to account for different volumes of sweat,” said Dr. Thavarajah. In clinical practice, finger sweat isoniazid could potentially serve as an adjunct or alternative to DOT in patients with TB.

Although adherence to the sampling protocol and possible patient distrust of the process (such as concerns over what else is being collected in their sweat) might be barriers to the use of a finger sweat strategy in the clinical setting, appropriate patient selection, patient training, and encouraging clinicians to incorporate this testing into practice could overcome these barriers, said Dr. Thavarajah.

However, more research is needed to study the finger sweat strategy in larger, real-world samples and to study accuracy and treatment adherence with monitoring in a population undergoing DOT, she said.

The study was supported by the Engineering & Physical Sciences Research Council and by Santander PhD Mobility Awards 2019. The researchers had no financial conflicts to disclose. Dr. Thavarajah had no financial conflicts to disclose.

In the current study, “I was struck by the correlation between the sweat and serum values of [isoniazid] and by the level of sophistication of noninvasive testing, being able to normalize for creatinine to account for different volumes of sweat,” said Dr. Thavarajah. In clinical practice, finger sweat isoniazid could potentially serve as an adjunct or alternative to DOT in patients with TB.

Although adherence to the sampling protocol and possible patient distrust of the process (such as concerns over what else is being collected in their sweat) might be barriers to the use of a finger sweat strategy in the clinical setting, appropriate patient selection, patient training, and encouraging clinicians to incorporate this testing into practice could overcome these barriers, said Dr. Thavarajah.

However, more research is needed to study the finger sweat strategy in larger, real-world samples and to study accuracy and treatment adherence with monitoring in a population undergoing DOT, she said.

The study was supported by the Engineering & Physical Sciences Research Council and by Santander PhD Mobility Awards 2019. The researchers had no financial conflicts to disclose. Dr. Thavarajah had no financial conflicts to disclose.

Analysis of finger sweat detected isoniazid in adults with tuberculosis (TB) for ≤ 6 hours after administration, based on data from a new pilot study.

Risk factors for TB treatment failure include poor medication compliance and insufficient exposure to medications, but measurement of drugs in samples of blood, saliva, or sweat can help assess adherence and inform dose adjustments, Katherine Longman, a PhD student at the University of Surrey, Guildford, England, and colleagues wrote.

Although TB is treatable, “it is well known that insufficient drug dosing leads to treatment failure and drug resistance, and so ensuring that patients have sufficient drug exposure is important,” said corresponding author Melanie J. Bailey, PhD, also of the University of Surrey.

“This can be carried out using blood, but blood is painful to collect and difficult to transport. Finger sweat offers a completely noninvasive way to sample patients,” but its use to determine medication adherence has not been examined, she said.

In a pilot study published in the International Journal of Antimicrobial Agents, the researchers reviewed data from 10 adults with TB who provided finger sweat, blood, and saliva samples at several time points ≤ 6 hours after receiving a controlled dose of isoniazid (median of 300 mg daily). They used liquid chromatography–mass spectrometry to examine the samples.

Overall, “isoniazid and acetyl isoniazid were detected in at least one finger sweat sample from all patients,” with detection rates of 96% and 77%, respectively, the researchers wrote. Given the short half-life of isoniazid, they used a window of 1-6 hours after administration. Isoniazid was consistently detected between 1 and 6 hours after administration, while acetyl isoniazid had a noticeably higher detection rate at 6 hours.

The researchers also examined creatinine to account for variability in volume of sweat samples, and found that finger sweat was significantly correlated to isoniazid concentration. The maximum isoniazid to creatinine ratio in finger sweat occurred mainly in the first hour after drug administration, and the activity of isoniazid in finger sweat over time reflected isoniazid concentration in serum more closely after normalization to creatinine, they said. The Pearson’s correlation coefficient (r) was 0.98 (P < .001; one-tailed), with normalization to creatinine, compared with r = 0.52 without normalization (P = .051).

The study findings were limited by several factors including the lack of knowledge of the last drug dose and lack of confirmation testing with an established method of analysis, the researchers noted. However, the results support the potential of the finger sweat test as a screening tool to indicate patients’ nonadherence or to identify patients at risk of low medication exposure.

“We were surprised that we were able to detect the drug in so many patient samples because the sample volume is so low, and so detection is challenging,” said Dr. Bailey. “We were also surprised that fingerprint and drug levels correlated so well after normalizing to creatinine. This is exciting as it unlocks the possibility to test drug levels, as well as providing a yes/no test.”

In practice, the finger sweat technique could reduce the burden on clinics by offering a completely noninvasive way to test a patient’s medication adherence. Looking ahead, more research is needed to explore whether creatinine normalization is widely applicable, such as whether it works for patients with abnormal kidney function, she added.
 

Noninvasive Option May Mitigate Treatment Challenges

The current study presents a strategy that might address current limitations in TB management, said Krishna Thavarajah, MD, a pulmonologist and director of the interstitial lung disease program at Henry Ford Hospital, Detroit, Michigan, in an interview.

Both self-administered treatment and directly observed therapy (DOT) for TB therapy have limitations, including adherence as low as 50% for TB regimens, she said. In addition, “DOT availability and efficacy can be limited by cost, personnel availability from an administration perspective, and by distrust of those being treated.”

An intervention combining an individualized walking program and education and significantly reduced low back pain recurrence in adults, compared with controls, based on data from approximately 700 individuals.

Exercise, including walking, is recommended to prevent recurrence of low back pain, but data on the effectiveness and cost-effectiveness of walking as an intervention are lacking, wrote Natasha C. Pocovi, PhD, of Macquarie University, Sydney, Australia, and colleagues.

In a study known as WalkBack, published in the Lancet, the researchers randomized 351 adults aged 18 years and older with a history of more than two prior episodes of low back pain to an intervention and 350 to no intervention.

The intervention consisted of six sessions of education and progressive walking with a physiotherapist over 6 months; both intervention and control groups were followed for a minimum of 12 months and a maximum of 36 months. The mean age of the participants was 54 years, and 81% were female. The primary outcome was the number of days to recurrence of low back pain severe enough to limit activity, based on monthly self-reports.

The intervention was significantly more effective at preventing activity-limiting low back pain recurrence, compared with no intervention (hazard ratio, 0.72; P = .0002), with a median of 208 days and 112 days to recurrence in the intervention and control groups, respectively.

The risk of any low back pain recurrence also was significantly reduced in the intervention group, compared with the controls (HR, 0.80; P = .0066); as was the risk of care-seeking recurrence of low back pain (HR, 0.57; P < .0001).

Overall, the experience of at least one adverse event over 12 months was similar between the intervention and control groups (52% and 54%, respectively), but significantly more adverse events related to lower extremities occurred in the intervention group, compared with the control group (100 vs 54). The intervention also was more likely to be cost effective, compared with a no-treatment control, the researchers wrote.

The findings were limited by several factors including the relatively homogeneous population and that neither the therapists nor participants were masked to group allocation. In addition, the study was conducted during the COVID-19 pandemic, so a telehealth model of video consultations was used instead of in-person meetings, but this protocol change allowed for inclusion of participants from diverse locations including rural and remote areas, the researchers said.

More research is needed to assess the implementation of a walking and exercise intervention as part of a discharge plan after an episode of low back pain and to examine the effectiveness of an intervention involving fewer sessions and a range of healthcare providers, they added. However, the results support the value of the intervention, which has a strong potential for successful implementation because of accessibility and low cost.
 

Preventive Interventions Need More Real-World Research

“Preventive interventions for back pain are an important yet neglected consideration,” Diarmuid Denneny, a doctoral candidate at Brunel University London, and Jackie Walumbe, PhD, of the University of Oxford (England), wrote in an accompanying editorial.

Although recurrence of low back pain is common, guidance on prevention and management is lacking, they said. Strengths of the current study include attention to patient and public preferences in the study design; however, the majority of the participants were of relatively high socioeconomic status and 89% reported post-secondary education.

“Given that pain is known to have a higher impact on marginalized and minoritized groups and those experiencing socioeconomic deprivation, we recommend caution in extrapolating these findings to different contexts,” the editorialists wrote.

They also cautioned that the complex nature of the intervention, which included not only walking but education and physiotherapist appointments, might make it difficult to isolate walking as the key factor in the patients’ improvement. The editorialists also emphasized the need for studies of similar interventions conducted by alternative providers including exercise professionals and digital platforms.

However, the WalkBack trial represents progress toward greater support for individuals with recurrent back pain and may be a foundation for other research involving how other forms of physical activity compare in improving back pain, with attention to the role of publish health in delivering physical activity interventions, they said.

The study was supported by the National Health and Medical Research Council, Australia. Dr. Pocovi disclosed scholarships funded by the National Health and Medical Research Council Low Back Pain Centre of Research Excellence (ANZBACK) and Macquarie University. Mr. Denneny disclosed support from an Economic and Social Research Council fellowship, and disclosed consulting fees from Live Well with Pain and Leva clinic; a grant from the Chartered Society of Physiotherapy.

Upadacitinib (Rinvoq) is now indicated for patients aged 2 years or older with active polyarticular juvenile idiopathic arthritis (pJIA) and psoriatic arthritis (PsA) who cannot tolerate or achieve adequate disease response with one or more tumor necrosis factor (TNF) blockers, according to a press release from manufacturer AbbVie. 

For the youngest patients, upadacitinib is also available as a weight-based oral solution (Rinvoq LQ) in addition to the previously available tablets, according to the company. JIA, which includes pJIA and juvenile PsA, affects nearly 300,000 children and adolescents in the United States, and alternatives to TNF inhibitor (TNFi) therapy are limited, according to the company. 

“Pediatric patients with pJIA and PsA can be severely limited in their ability to complete daily physical tasks and participate in everyday activities. Understanding their needs today and knowing the likelihood of disease in adulthood underscores the need for additional treatment options,” Aarat Patel, MD, a pediatric rheumatologist at Bon Secours Rheumatology Center, Richmond, Virginia, said in the press release. “Having a treatment option available for patients who do not respond well to a TNFi addresses a need for the healthcare community, patients, and their families,” he said.

Upadacitinib, a Janus kinase (JAK) inhibitor, is being studied for multiple immune-mediated inflammatory diseases. The new indication was supported by data from adults with rheumatoid arthritis (RA) and PsA, 51 pediatric patients with pJIA and active polyarthritis, and safety data from 83 pediatric patients aged 2 years to younger than 18 years with pJIA and active polyarthritis. 

In the studies, the drug’s safety in pediatric patients was similar to the known safety profile in adults, which includes increased risk for serious infections such as tuberculosis, cancer, immune system problems, blood clots, and serious allergic reactions to components of the drug, according to the press release. However, the safety and effectiveness of upadacitinib for pJIA and PsA in patients younger than 2 years are unknown.

“Upadacitinib plasma exposures in pediatric patients with pJIA and PsA at the recommended dosage are predicted to be comparable to those observed in adults with RA and PsA based on population pharmacokinetic modeling and simulation,” according to the press release.

Currently, upadacitinib’s only other pediatric indication is for moderate to severe atopic dermatitis in children aged 12 years or older. Upadacitinib also is indicated for treatment of adults with moderate to severe RA, active PsA, active ankylosing spondylitis, active nonradiographic axial spondyloarthritis, and moderate to severe ulcerative colitis and Crohn’s disease, but safety and efficacy for its use in treatment of these conditions in children and adolescents is unknown.

Upadacitinib also is being studied in phase 3 trials for treatment of conditions including alopecia areata, ankylosing spondylitis, atopic dermatitis, axial spondyloarthritis, Crohn’s disease, giant cell arteritis, hidradenitis suppurativa, psoriatic arthritis, RA, systemic lupus erythematosus, Takayasu arteritis, ulcerative colitis, and vitiligo, according to the press release.

Non-respiratory symptoms including poor sleep, fatigue, pain, anxiety, and depressive symptoms were prevalent among adults with cystic fibrosis (AwCF) and persisted after 1 year of follow-up, based on data from more than 200 individuals in a study presented at the American Thoracic Society (ATS) 2024 International Conference.

“People with cystic fibrosis have qualitatively reported burden from extrapulmonary symptoms that were not being addressed by their health care providers; this is the first study to examine these symptoms concurrently in a large sample over time,” said lead author Kristin A. Riekert, PhD, of Johns Hopkins University, Baltimore, in an interview.

Previous cross-sectional studies have shown a high prevalence of poor sleep quality, fatigue, pain, depression, and anxiety among AwCF, but longitudinal data showing the persistence of symptoms are lacking, Dr. Riekert and colleagues noted in their abstract.
 

Sleep Quality, Anxiety, and Other Assessments

The researchers recruited a total of 236 AwCF aged 18 years and older from two cystic fibrosis (CF) centers between April 2021 and August 2022. They examined the prevalence of poor sleep quality, fatigue pain, depression, and anxiety in AwCF on the basis of five assessments: At baseline and at 3, 6, 9, and 12 months.

Participants were assessed via an online survey using the Fatigue Severity Scale (cutoff, > 4), Pittsburgh Sleep Quality Index (cutoff, > 5), Patient Health Questionnaire (cutoff, > 9), Generalized Anxiety Disorder (cutoff, > 9), and PROMIS Pain Intensity (cutoff, > 50 T score). Chronic symptoms were defined as positive scores on four or more assessments for individuals who completed four or five time-point assessments. The mean age of the participants was 37 years, 52% were women, 95% were non-Hispanic White, and 86% had been prescribed CF modulator therapy.

At 12 months, 62% of participants reported poor sleep, and 34% reported fatigue. In addition, 17% reported depressive symptoms, 14% reported anxiety symptoms, and 7% reported pain at 12 months.

Overall, 49% of participants met the criteria for chronic poor sleep quality, and 29% met the criteria for chronic fatigue, with positive assessments at four or more time points over the course of a year. In addition, 40%, 30%, and 18% of participants reported taking medication in the past 7 days for pain, mental health, and sleep, respectively.

The findings suggest that patients with CF might benefit from routine assessments of non-pulmonary symptoms in clinical care and from access to health care providers, including mental health professionals, to address non-pulmonary concerns, the researchers wrote in their abstract.

“We delayed starting the study until elexacaftor/tezacaftor/ivacaftor (ETI) was FDA-approved because there was an assumption that people with CF would have less fatigue because of respiratory improvements from ETI,” Dr. Riekert told this news organization. “Instead, the prevalence of fatigue and poor sleep quality was higher and more chronic than we had anticipated,” she noted.

However, “we were pleasantly surprised that depression and anxiety, while still prevalent, were less prevalent and chronic than previously reported,” Dr. Riekert said in an interview. “We attribute this to the CF Foundation’s mental health initiative that has increased the frequency of annual screening for depression and anxiety and provided resources to help people with cystic fibrosis obtain mental health services,” she said.

The study findings suggest that clinicians should assess people with CF for chronic fatigue and poor sleep along with depression and anxiety and provide treatment or referral, Dr. Riekert said. “For example, cognitive behavioral therapy can effectively treat all the symptoms that were measured in our study,” she noted.

Limitations of the study include the lack of data on how the non-respiratory symptoms interact with respiratory symptoms or pulmonary exacerbations, said Dr. Riekert. “While we assessed these symptoms five times, it was for a year; longer-term follow-up seems merited given our findings,” she said. In addition, “we need to study approaches to make cognitive behavioral therapy and other therapy more accessible for people with cystic fibrosis,” Dr. Riekert said.
 

Targeting Non-Pulmonary Dimensions of CF Care

The current study highlights an aspect of quality of life that is often forgotten when managing adults with CF and may affect their well-being despite effective therapy to improve function and prolong life, said Wissam Chatila, MD, professor of thoracic medicine and surgery at the Lewis Katz School of Medicine at Temple University, Philadelphia, in an interview.

The high incidence of poor sleep, fatigue, depression, and anxiety seen in the current study was “somewhat surprising,” Dr. Chatila said. Also somewhat surprising was the chronicity of the symptoms considering the cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies (designed to correct the malfunctioning protein made by the CFTR gene) that have changed the face of CF, he noted.

However, recent growth in the number of adult patients with CF (more than 50% in certain countries) has led to a change in pathologies that physicians have to manage, and the current study addresses some of the emerging pathologies, said Dr. Chatila.

“Beyond demonstrating survival data from registries and other epidemiologic studies, this study sheds light on the need to address patient-reported outcomes that may or may not be directly related to the pulmonary and GI effects of the CFTR modulators,” he said. “Recognizing the extent of the dysfunction that many CF patients continue to suffer from will eventually lead to identifying factors that contribute to poor outcomes and the mechanisms involved,” he added.

Overall, the current study illustrates the potential benefits of offering personalized medicine to adults with CF that improves not only their physical function but also their mental health, Dr. Chatila said.

Non-respiratory symptoms including poor sleep, fatigue, pain, anxiety, and depressive symptoms were prevalent among adults with cystic fibrosis (AwCF) and persisted after 1 year of follow-up, based on data from more than 200 individuals in a study presented at the American Thoracic Society (ATS) 2024 International Conference.

“People with cystic fibrosis have qualitatively reported burden from extrapulmonary symptoms that were not being addressed by their health care providers; this is the first study to examine these symptoms concurrently in a large sample over time,” said lead author Kristin A. Riekert, PhD, of Johns Hopkins University, Baltimore, in an interview.

Previous cross-sectional studies have shown a high prevalence of poor sleep quality, fatigue, pain, depression, and anxiety among AwCF, but longitudinal data showing the persistence of symptoms are lacking, Dr. Riekert and colleagues noted in their abstract.
 

Sleep Quality, Anxiety, and Other Assessments

The researchers recruited a total of 236 AwCF aged 18 years and older from two cystic fibrosis (CF) centers between April 2021 and August 2022. They examined the prevalence of poor sleep quality, fatigue pain, depression, and anxiety in AwCF on the basis of five assessments: At baseline and at 3, 6, 9, and 12 months.

Participants were assessed via an online survey using the Fatigue Severity Scale (cutoff, > 4), Pittsburgh Sleep Quality Index (cutoff, > 5), Patient Health Questionnaire (cutoff, > 9), Generalized Anxiety Disorder (cutoff, > 9), and PROMIS Pain Intensity (cutoff, > 50 T score). Chronic symptoms were defined as positive scores on four or more assessments for individuals who completed four or five time-point assessments. The mean age of the participants was 37 years, 52% were women, 95% were non-Hispanic White, and 86% had been prescribed CF modulator therapy.

At 12 months, 62% of participants reported poor sleep, and 34% reported fatigue. In addition, 17% reported depressive symptoms, 14% reported anxiety symptoms, and 7% reported pain at 12 months.

Overall, 49% of participants met the criteria for chronic poor sleep quality, and 29% met the criteria for chronic fatigue, with positive assessments at four or more time points over the course of a year. In addition, 40%, 30%, and 18% of participants reported taking medication in the past 7 days for pain, mental health, and sleep, respectively.

The findings suggest that patients with CF might benefit from routine assessments of non-pulmonary symptoms in clinical care and from access to health care providers, including mental health professionals, to address non-pulmonary concerns, the researchers wrote in their abstract.

“We delayed starting the study until elexacaftor/tezacaftor/ivacaftor (ETI) was FDA-approved because there was an assumption that people with CF would have less fatigue because of respiratory improvements from ETI,” Dr. Riekert told this news organization. “Instead, the prevalence of fatigue and poor sleep quality was higher and more chronic than we had anticipated,” she noted.

However, “we were pleasantly surprised that depression and anxiety, while still prevalent, were less prevalent and chronic than previously reported,” Dr. Riekert said in an interview. “We attribute this to the CF Foundation’s mental health initiative that has increased the frequency of annual screening for depression and anxiety and provided resources to help people with cystic fibrosis obtain mental health services,” she said.

The study findings suggest that clinicians should assess people with CF for chronic fatigue and poor sleep along with depression and anxiety and provide treatment or referral, Dr. Riekert said. “For example, cognitive behavioral therapy can effectively treat all the symptoms that were measured in our study,” she noted.

Limitations of the study include the lack of data on how the non-respiratory symptoms interact with respiratory symptoms or pulmonary exacerbations, said Dr. Riekert. “While we assessed these symptoms five times, it was for a year; longer-term follow-up seems merited given our findings,” she said. In addition, “we need to study approaches to make cognitive behavioral therapy and other therapy more accessible for people with cystic fibrosis,” Dr. Riekert said.
 

Targeting Non-Pulmonary Dimensions of CF Care

The current study highlights an aspect of quality of life that is often forgotten when managing adults with CF and may affect their well-being despite effective therapy to improve function and prolong life, said Wissam Chatila, MD, professor of thoracic medicine and surgery at the Lewis Katz School of Medicine at Temple University, Philadelphia, in an interview.

The high incidence of poor sleep, fatigue, depression, and anxiety seen in the current study was “somewhat surprising,” Dr. Chatila said. Also somewhat surprising was the chronicity of the symptoms considering the cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies (designed to correct the malfunctioning protein made by the CFTR gene) that have changed the face of CF, he noted.

However, recent growth in the number of adult patients with CF (more than 50% in certain countries) has led to a change in pathologies that physicians have to manage, and the current study addresses some of the emerging pathologies, said Dr. Chatila.
