Hepatic Fat Reduction Due to Resmetirom in Patients With Nonalcoholic Steatohepatitis Is Associated With Improvement of Quality of Life.

BACKGROUND & AIMS: Nonalcoholic steatohepatitis (NASH) is a chronic liver disease associated with adverse clinical outcomes and impaired health-related quality of life (HRQL). METHODS: Patients with biopsy-proven non-cirrhotic NASH with hepatic fat fraction of ≥10% by magnetic resonance imaging-proton density fat fraction were enrolled in a phase 2, multicenter, double-blind, randomized, placebo-controlled study of resmetirom. HRQL was assessed using Short Form-36 throughout 36 weeks of treatment. RESULTS: One hundred twenty-five NASH patients were enrolled (50 ± 11 years old, 50% male, 94% white, body mass index 35 ± 6 kg/m2, 39% with diabetes mellitus). Of these, 84 patients received 80 mg of resmetirom daily, and 41 received placebo. At baseline, HRQL scores were not different from general population norms (Physical Component Summary [PCS] 47.9 ± 9.3 vs 50, Mental Component Summary 50.4 ± 10.0 vs 50; all P > .05). By treatment week 12, patients who received resmetirom experienced improvement of Bodily Pain and Short Form-6D utility scores (P < .05); no HRQL improvement was noted in placebo (all P > .05). Improvement in PCS continued up to week 36 of treatment with resmetirom, again with no improvement in placebo group (all P > .05). Adjusted for the baseline score and clinicodemographic confounders, meeting the endpoint of a decrease in proton density fat fraction of ≥30% by week 12 (met by 54 of 116 treatment completers; 47 of 54 on resmetirom) was independently associated with greater improvements in Physical Functioning and PCS scores at week 36 (P < .05). Patients with improvement in NASH and fibrosis on liver biopsy also showed improvement in components of HRQL. CONCLUSIONS: Patients with NASH treated who improved their hepatic fat fraction and/or Nonalcoholic Fatty Liver Disease Activity Score on serial liver biopsy experienced improvement of HRQL. Further studies are needed to confirm long-term sustainability of that improvement. CLINICALTRIALS: gov #NCT02912260.

Is asthma associated with cognitive impairments? A meta-analytic review.

INTRODUCTION: Asthma is a chronic disease with significant health burden and socioeconomic and racial/ethnic disparities related to diagnosis and treatment. Asthma primarily affects the lungs, but can impact brain function through direct and indirect mechanisms. Some studies have suggested that asthma negatively impacts cognition, while others have failed to identify asthma-related cognitive compromise. We aimed to conduct a meta-analysis of cognition in individuals with asthma compared to that in healthy controls. We also examined the impact of some key potential moderators. METHOD: Data on cognitive outcome measures and sociodemographic, illness-related, and study-related variables were extracted from studies reporting cognitive test performance in individuals with asthma compared to that in controls. RESULTS: There was no evidence of publication bias. A random-effects model examining differences in task performance between 2017 individuals with asthma and 2131 healthy controls showed significant effects in the small to medium range. Cognitive deficits associated with asthma were global, with strongest effects on broader measures involving academic achievement and executive functioning, but with additional impact on processing speed, global intellect, attention, visuospatial functioning, language, learning, and memory. Severity of asthma was a key moderator, with greatest cognitive deficits associated with severe asthma. Cognitive burden was also greatest in asthma patients who were younger, males, from low socioeconomic backgrounds, and from racial/ethnic minorities. Effects were independent of type of population (child versus adult), type of study (norm-referenced versus control-referenced), or reported use of oral or inhaled corticosteroid medications. CONCLUSIONS: There is cognitive burden associated with asthma, particularly among vulnerable groups with severe asthma. This could be due to increased risk of intermittent cerebral hypoxia in severe asthma. The clinical need to assess cognition in individuals with asthma is underscored.
