Sofosbuvir-based regimen is safe and effective for hepatitis C infected patients with stage 4–5 chronic kidney disease: a systematic review and meta-analysis

BACKGROUND: Whether sofosbuvir is suitable for hepatitis C virus (HCV) infected patients with severe renal impairment is inconclusive. This systematic review aims to evaluate the safety and effectiveness of SOF-based regimen in the setting of stage 4 and 5 chronic kidney disease (CKD). METHODS: We conducted a systematic literature search in PubMed, Web of Science, EMBASE and Google Scholar with searching strategy: (sofosbuvir OR Sovaldi OR Harvoni OR Epclusa OR Vosevi) AND (severe kidney impairment OR severe renal impairment OR end-stage renal disease OR dialysis OR renal failure OR ESRD OR renal insufficiency OR hepatorenal syndrome OR HRS). Sustained virological response (SVR12/24) rate and serious adverse event (SAE) rate with 95% confidence intervals were aggregated. Subgroup analysis was implemented to evaluate the impact of treatment strategy and patient characteristics. RESULTS: Twenty-one studies met inclusion criteria, totaling 717 HCV infected patients with CKD stage 4 or 5 (58.4% on dialysis). Pooled SVR12/24 was 97.1% (95% CI 93.9–99.3%), and SAE rate was 4.8% (95% CI 2.1–10.3%). There was no significant difference at SVR12/24 (97.1% vs 96.2%, p = 0.72) or SAE rate (8.8% vs 2.9%, p = 0.13) between subgroups applying full or decreased dose of sofosbuvir. Cirrhotic and non-cirrhotic patients achieved comparable sustained virological response (RR 0.93, 95% CI 0.85–1.02). Four studies reported eGFR/serum creatinine pre- and post- treatment, with no significant modification. CONCLUSIONS: Our study suggests SOF-based regimen might be used safely and effectively in patients living with HCV infection/stage 4–5 CKD, with normal and reduced dose of sofosbuvir. Prospective and well-controlled trials are needed to confirm these findings. TRIAL REGISTRATION: PROSPERO CRD42018107440.
