Boceprevir is highly effective in treatment-experienced hepatitis C virus-positive genotype-1 menopausal women

AIM: To investigate the safety/efficacy of Boceprevirbased triple therapy in hepatitis C virus (HCV)-G1 menopausal women who were historic relapsers, partial-responders and null-responders. METHODS: In this single-assignment, unblinded study, we treated fifty-six menopausal women with HCV-G1, 46% F3-F4, and previous PEG-α/RBV failure (7% null, 41% non-responder, and 52% relapser) with 4 wk lead-in with PEG-IFNα2b/RBV followed by PEGIFNα2b/RBV+Boceprevir for 32 wk, with an additional 12 wk of PEG-IFN-α-2b/RBV if patients were HCV-RNA-positive by week 8. In previous null-responders, 44 wk of triple therapy was used. The primary objective of retreatment was to verify whether a sustained virological response (SVR) (HCV RNA undetectable at 24 wk of follow-up) rate of at least 20% could be obtained. The secondary objective was the evaluation of the percent of patients with negative HCV RNA at week 4 (RVR), 8 (RVR BOC), 12 (EVR), or at the end-of-treatment (ETR) that reached SVR. To assess the relationship between SVR and clinical and biochemical parameters, multiple logistic regression analysis was used. RESULTS: After lead-in, only two patients had RVR; HCV-RNA was unchanged in all but 62% who had ≤ 1 logio decrease. After Boceprevir, HCV RNA became undetectable at week 8 in 32/56 (57.1%) and at week 12 in 41/56 (73.2%). Of these, 53.8% and 52.0%, respectively, achieved SVR. Overall, SVR was obtained in 25/56 (44.6%). SVR was achieved in 55% previous relapsers vs. 41% non-responders (Ρ = 0.250), in 44% F0-F2 vs 54% F3-F4 (Ρ = 0.488), and in 11/19 (57.9%) of patients with cirrhosis. At univariate analysis for baseline predictors of SVR, only previous response to antiviral therapy (OR = 2.662, 95%CI: 0.957-6.881, Ρ= 0.043), was related with SVR. When considering "on treatment" factors, 1 log10 HCV RNA decline at week 4 (3.733, 95%CI: 1.676-12.658, Ρ= 0.034) and achievement of RVR BOC (7.347, 95%CI: 2.156-25.035, Ρ= 0.001) were significantly related with the SVR, al-though RVR BOC only (6.794, 95%CI: 1.596-21.644, Ρ = 0.010) maintained significance at multivariate logistic regression analysis. Anemia and neutropenia were managed with Erythropoietin and Filgrastim supplementation, respectively. Only six patients discontinued therapy. CONCLUSION: Boceprevir obtained high SVR response independent of previous response, RVR or baseline fibrosis or cirrhosis. RVR BOC was the only independent predictor of SVR

Early menopause is associated with lack of response to antiviral therapy in women with chronic hepatitis C.

BACKGROUND AND 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-naïve 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 < .0001) but as frequently as men (51.1%; 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

Peginterferon-A_2B plus ribavirin is more effective than peginterferon-A_2A plus ribavirin in menopausal women with chronic hepatitis C

Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naïve patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44.2% of Peg-IFNα-2a-treated patients and in 51.2% of Peg-IFNα-2b-treated patients (intention-to-treat; P = 0.139). Age, fibrosis stage and genotype 2 and 3 were independently associated with SVR by multivariate analysis. Analysing by gender, the difference in SVR between PEG-IFNα types was not significant in men but highly significant in women (Peg-IFNα-2a:39.1%vs Peg-IFNα-2b:54.4%, P = 0.007). This was attributable to a higher SVR rate with Peg-IFNα-2b in the difficult postmenopausal population (26.9% Peg-IFNα-2a vs 46.0% Peg-IFNα-2b, P = 0.040). In women, absence of menopause, genotype 2 hepatitis C virus infection and use of Peg-IFNα-2b were independently associated with SVR. In conclusion, predictive factors for SVR are different in men and women. Factors differing between genders are menopause, severe steatosis and peg-interferon used. The higher SVR rate with Peg-IFNα-2b in menopausal women is likely attributable to more favourable pharmacokinetics that allows Peg-IFNα-2b to reach visceral fat and oppose the increased cytokine production and enhanced inflammatory status in menopause
