Use Of Glecaprevir/Pibrentasvir In Patients With Chronic Hepatitis C Virus Infection And Severe Renal Impairment

[GRAPHICS]Background/Aims: Data on treatment efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) for chronic hepatitis C virus (HCV) infection in Asian patients with severe renal impairment are limited. This study aimed to study the treatment and side effects of GLE/PIB in these patients infected with non-1 genotype (GT) HCV.Methods: We prospectively recruited patients with Child's A cirrhosis and eGFR <30 mL/min/1.73 m(2) in Hong Kong and Taiwan during 2017-2018 to receive GLE/PIB treatment.Results: Twenty-one patients (GT2, n=7; GT3, n= 6; and GT6, n=8) received GLE/PIB for 11.2 +/- 1.8 weeks. All except one were treatment-naive. GLE/PIB was initiated in 16 patients while on dialysis (seven on peritoneal dialysis [PD] and nine on hemodialysis) and in five patients before dialysis. One patient died of PD-related peritonitis during treatment and two were lost to follow up. The SVR12 rate in the remaining 18 patients was 100%. All patients achieved undetectable levels at 4-, 12-, 24- and 48-week after treatment. Patients with deranged alanine aminotransferase showed normalization after 4 weeks and the response was sustained for 48 weeks. No significant adverse event was observed.Conclusions: GLE/PIB treatment was associated with high efficacy and tolerability in HCV-infected patients with severe renal impairment.
