Chen, Lee, Chiu, Tung, Chiu, Cheng (2019) Real-world effectiveness and safety of ledipasvir/sofosbuvir for genotype 6 chronic hepatitis C patients in Taiwan Journal of gastroenterology and hepatology ()
Infection with hepatitis C virus (HCV) genotype (GT) 6 is uncommon in Taiwan, and reports of ledipasvir/sofosbuvir (LDV/SOF) treatment for GT6 are few. This study evaluates the effectiveness and safety of LDV/SOF in treating chronic hepatitis C (CHC) patients with GT6 infection. CHC patients that were infected with GT6 and treated for 12 weeks with LDV/SOF at two hospitals were enrolled. All patients were followed for an additional 12 weeks after the completion of LDV/SOF treatment. Demographics, HCV viral load, lipid and sugar profiles, and adverse events were recorded and reviewed. A total of 127 patients were enrolled. Cirrhosis was found in 68.2% of them. Sustained virological response (SVR), determined by per-protocol analysis, was 97.6%. The SVR rates for cirrhosis versus non-cirrhosis (96.5% vs 100%, P = 0.229) and low versus high viral load (cutoff value: 106 IU/mL; 100% vs 95.6%, P = 0.108) were similar. Following HCV clearance, significantly lower glycosylated hemoglobin was present both in patients with or without diabetes mellitus. Twenty-three (18.1%) patients exhibited adverse events, and each adverse event presented with an incidence of 0.8% to 3.1%. Neuropsychiatric symptoms were the most common. During treatment, 18 patients (14.2%) had alanine aminotransferase elevations consistent with more than grade 1 abnormalities, and none had signs of decompensation. Renal function remained unchanged. The high SVR and excellent safety of LDV/SOF treatment for GT6 CHC patients suggest that LDV/SOF is a favorable option for treating GT6 CHC patients in Taiwan and Asia. © 2019 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.
