Early Menopause Is Associated With Lack of Response to Antiviral Therapy in Women With Chronic Hepatitis C

Background & Aims Chronic hepatitis C (CHC) and liver fibrosis progress more rapidly in men and menopausal women than in women of reproductive age. We investigated the associations among menopause, sustained virologic response (SVR), and liver damage in patients with CHC. Methods We performed a prospective study of 1000 consecutive, treatment-naive patients 18 years of age and older with compensated liver disease from CHC. Liver biopsy samples were analyzed (for fibrosis, inflammation, and steatosis) before patients received standard antiviral therapy. From women (n = 442), we collected data on the presence, type, and timing of menopause; associated hormone and metabolic features; serum levels of interleukin-6; and hepatic tumor necrosis factor (TNF)-α. Results Postmenopausal women achieved SVRs less frequently than women of reproductive age (46.0% vs 67.5%; P P = .283). By multivariate regression analysis, independent significant predictors for women to not achieve an SVR were early menopause (odds ratio [OR], 8.055; 95% confidence interval [CI], 1.834–25.350), levels of γ-glutamyl transpeptidase (OR, 2.165; 95% CI, 1.364–3.436), infection with hepatitis C virus genotype 1 or 4 (OR, 3.861; 95% CI, 2.433–6.134), and cholesterol levels (OR, 0.985; 95% CI, 0.971–0.998). Early menopause was the only independent factor that predicted lack of an SVR among women with genotype 1 hepatitis C virus infection (OR, 3.933; 95% CI, 1.274–12.142). Baseline levels of liver inflammation, fibrosis, steatosis, serum interleukin-6 ( P = .04), and hepatic TNF-α ( P = .007) were significantly higher among postmenopausal women than women of reproductive age. Conclusions Among women with CHC, early menopause was associated with a low likelihood of SVR, probably because of inflammatory factors that change at menopause.
