Abstract
BACKGROUND: Chronic kidney disease (CKD) was a relative contraindication to hepatitis C virus (HCV) treatment in the interferon/ribavirin era. AIM: To determine the efficacy, tolerability and safety of sofosbuvir/ledipasvir (SOF/LDV) and paritaprevir/ritonavir/ombitasvir/dasabuvir (PrOD) regimens in persons with CKD. METHODS: We identified persons initiated on a SOF/LDV or PrOD regimen from October 30, 2014 to April 30, 2016. We excluded those with missing HCV genotype or eGFR values. We determined treatment completion and sustained virologic response (SVR) rates, and proportion developing worsening renal function or grade 3/4 haematologic toxicity. RESULTS: Among 13 663 persons on SOF/LDV±ribavirin, 14% and 1% persons had CKD Stage 3 and 4-5 respectively, 67.8% completed treatment, 98.2% achieved SVR. Treatment completion or SVR rates did not decline with advanced CKD or ribavirin administration. Among 3961 persons on PrOD±ribavirin, 9% and 3% persons had CKD Stage 3 and 4-5, respectively, 74.0% completed treatment and 98.2% achieved SVR. A decrease in treatment completion rates was seen in CKD stage 4-5 and those on ribavirin, but this did not impact SVR rates. A >10 mL/min/1.73 m2 drop in eGFR from baseline was observed in 30%-38% of persons with baseline eGFR ≥60 mL/min/1.73 m2 , but in only 0%-6% with CKD4-5. Grade 3/4 anaemia was more frequent in persons with CKD4-5, but ribavirin co-administration did not appear to affect this. CONCLUSIONS: SOF/LDV and PrOD achieved high SVR rates in CKD population. Treatment completion rates were lower than expected. A decline in eGFR and development of anaemia were observed in a substantial proportion of persons, but the clinical implications remain unclear.
