Abstract PURPOSE: To appraise the incidence of liver toxicity in a population of patients receiving fosamprenavir/ritonavir (FPV/r) with a high frequency of viral hepatitis co-infection. METHOD: 636 patients, 341 (54\%) with HCV antibodies and 38 (5.6\%) bearing serum HBsAg, were recruited. All of them received FPV/r 700/100 twice every day. 93 (27\%) patients who tested positive for HCV antibodies showed an AST to platelet ratio index (APRI) higher than 1.5, consistent with significant liver fibrosis. RESULTS: After a median (range) follow-up time of 6.91 (0.46-20.66) months, 3 (0.47\%) patients developed grade 3 ALT elevation. All the former patients were hepatitis virus co-infected, 2 with hepatitis C virus and 1 with hepatitis B virus. The frequency of grade 3 ALT elevation in patients with HCV antibodies was 0.58\% and in those harbouring HBsAg it was 2.63\%. 4 (0.62\%) patients suffered from a liver decompensation and 1 died due to a hepatic cause while on follow-up. No patients with APRI equal to or higher than 1.5 showed grade 3 ALT elevation. CONCLUSION: The incidence of adverse hepatic events in patients receiving FPV/r including combinations seems to be low, even in subjects co-infected with hepatitis virus and in those with significant liver fibrosis.
