Gender and menopause impact severity of fibrosis among patients with nonalcoholic steatohepatitis.

ABSTRACT: Estrogens inhibit stellate cell activation and fibrogenesis. Thus, gender and reproductive states may influence the degree of fibrosis in patients with nonalcoholic steatohepatitis (NASH). To investigate the association between gender, menopause, and the severity of liver fibrosis in patients with NASH, we analyzed 541 adult patients enrolled from our Duke Liver Clinics (n?=?338) and the Duke Metabolic and Weight Loss Surgery Program (n?=?203) who had a histologic diagnosis of NASH. Multiple ordinal logistic regression models were used to assess the association between gender, menopause, and severity of liver fibrosis. Overall, men, premenopausal, and postmenopausal women composed 35.1%, 28.4%, and 36.5% of the population, respectively. The mean age was 48 years and 22% had advanced fibrosis. After adjusting for covariates (enrolling site, grades of portal inflammation, and hepatocyte ballooning) and potential confounders (race, body mass index, diabetes/prediabetes, hypertension), adjusted cumulative odd ratio (ACOR) and 95% confidence interval (CI) for greater fibrosis severity was 1.4 (0.9, 2.1) (P?=?0.17) for postmenopausal women and 1.6 (1.0, 2.5) (P?=?0.03) for men, having premenopausal women as a reference. There was borderline interaction between gender and age group divided by age 50, the average age at menopause in the U.S. (P?=?0.08): ACOR and 95% CI of having greater fibrosis severity in men compared to women was 1.8 (1.1, 2.9) for patients with age <50 years (P?=?0.02) and 1.2 (0.7, 2.1) for patients with age ?50 years (P?=?0.59).Men are at a higher risk of having more severe fibrosis compared to women before menopause, while postmenopausal women have a similar severity of liver fibrosis compared to men. These findings may be explained by the protective effects of estrogen against fibrogenesis.

Project description:Fatigue and pruritus are common in patients with chronic liver diseases of all etiologies, but clinical awareness is mostly restricted to those with cholestatic liver diseases. We assessed the impact of fatigue and pruritus on patient-reported outcomes (PROs) of patients with advanced nonalcoholic steatohepatitis (NASH). Specifically, PROs (Short Form-36, Chronic Liver Disease Questionnaire-NASH, Euro-Qol 5 Dimension, and Work Productivity and Activity Impairment instruments) were assessed at baseline in patients with histologically confirmed bridging fibrosis (F3) or compensated cirrhosis (F4) due to NASH enrolled in STELLAR 3 and 4. Presence of fatigue and pruritus were indicated by a score of 4 or less on the respective items of the Chronic Liver Disease Questionnaire-NASH (scale range, 1-7). Among the included 1,669 patients with advanced NASH (mean age = 58 ± 9 years, 48% F3, 42% with psychiatric comorbidities), 33% and 27% had fatigue and pruritus, respectively. Patients with NASH with fatigue were younger, more likely to be female, cirrhotic, and diabetic, and had higher body mass index and more comorbidities (all P < 0.05). All PRO scores of patients with fatigue were significantly impaired (mean up to -31% of a PRO range size in comparison to patients without fatigue). In multivariate analysis, predictors of fatigue included diabetes, history of depression or nervous system comorbidities, and lower serum albumin (P < 0.05). Patients with pruritus had demographic characteristics similar to those with fatigue, but a higher prevalence of dermatologic comorbidities. All PROs were impaired (by up to -19% of a range size, all P < 0.01) in patients with NASH with pruritus. Female gender, lower serum albumin, and a history of depression, nervous system, and dermatologic comorbidities were associated with increased risk of pruritus (P < 0.05). Conclusion: Clinically significant fatigue and pruritus are common in patients with advanced NASH, and these symptoms negatively affect PROs.

Project description:UnlabelledThe characteristics of nonalcoholic fatty liver disease (NAFLD) in elderly patients are unknown. Therefore, we aimed to examine the differences between elderly and nonelderly patients with NAFLD and to identify determinants of nonalcoholic steatohepatitis (NASH) and advanced fibrosis (bridging fibrosis or cirrhosis) in elderly patients. This is a cross-sectional analysis of adult participants who were prospectively enrolled in the NASH Clinical Research Network studies. Participants were included based on availability of the centrally reviewed liver histology data within 1 year of enrollment, resulting in 61 elderly (age ≥65 years) and 735 nonelderly (18-64 years) participants. The main outcomes were the presence of NASH and advanced fibrosis. Compared to nonelderly patients with NAFLD, elderly patients had a higher prevalence of NASH (56% versus 72%, P = 0.02), and advanced fibrosis (25% versus 44%, P = 0.002). Compared to nonelderly patients with NASH, elderly patients with NASH had higher rates of advanced fibrosis (35% versus 52%, P = 0.03), as well as other features of severe liver disease including the presence of ballooning degeneration, acidophil bodies, megamitochondria, and Mallory-Denk bodies (P ≤ 0.05 for each). In multiple logistic regression analyses, independent determinants of NASH in elderly patients included higher aspartate aminotransferase (AST) (odds ratio [OR] = 1.12, P = 0.007) and lower platelets (OR = 0.98, P = 0.02); and independent determinants of advanced fibrosis included higher AST (OR = 1.08, P = 0.007), lower alanine aminotransferase value (OR = 0.91, P = 0.002), and an increased odds of having low high-density lipoprotein (OR = 8.35, P = 0.02).ConclusionElderly patients are more likely to have NASH and advanced fibrosis than nonelderly patients with NAFLD. Liver biopsy may be considered in elderly patients and treatment should be initiated in those with NASH and advanced fibrosis.
