Tolerability and efficacy of anti‐HBV nucleos(t)ide analogues in HBV‐DNA‐positive cirrhotic patients with HBV/HCV dual infection

Abstract

We evaluated tolerability and virological and clinical impact of anti-Hepatitis B Virus (HBV) nucleos(t)ide analogues in cirrhotic patients with HBV/Hepatitis C Virus (HCV) coinfection. The virological and clinical course of 24 consecutive HBsAg/HBV-DNA/anti-HCV-positive patients with cirrhosis was compared with that of 24 HBsAg/HBV-DNA-positive, anti-HCV-negative cirrhotic patients, pair-matched for age (±5 years), sex, HBeAg/anti-HBe status and Child-Pugh class. Patients in both groups were previously untreated with oral antiviral agents at enrollment and were treated for at least 24 months (range 24-54). At the 12th and 18th month of treatment, HBV-DNA was negative in 21 (87.5%) and 23 (95.8%) patients with hepatitis B and C and in 20 (83.3%) and 22 (91.6%) in patients with isolated HBV; all patients in both groups were HBV-DNA-negative at month 24 and at subsequent observations. Treatment was well tolerated by all patients in both groups. At the last observation (for co-infected patients, median 44 months and range 24-54; for mono-infected patients, median 40 months and range 24-54), a deterioration in Child class was observed in eight (47%) of 17 patients in patients with both HBV and HCV who were HCV-RNA-positive at baseline, but in none of seven HCV-RNA-negative patients in the same group, and in one patient (4.2%) in the mono-infected patients. Reactivation of HCV infection was relatively infrequent (12.5% of cases) and never associated with a clinical deterioration. Treatment with nucleotides in HBsAg/HBV-DNA/anti-HCV-positive patients with cirrhosis showed a favourable virological effect in all cases, but a favourable clinical result only in the HCV-RNA-negative at baseline.
