BACKGROUND AND AIMS: The advent of direct-acting antiviral agents promises to change the management of hepatitis C virus infection (HCV) in patients with chronic kidney disease (CKD), a patient group in which the treatment of hepatitis C was historically challenging. We investigated the safety and efficacy of all-oral, interferon-free direct-acting antiviral agents for the treatment of hepatitis C in a 'real-world' cohort of patients with CKD.
METHODS: We performed an observational single-arm multi-centre study in a large (n=198) cohort of patients with stage 1-3 CKD who underwent antiviral therapy with DAAs for the treatment of HCV. The primary end-point was sustained virologic response (serum HCV RNA <15IU/mL, 12 weeks after treatment ended) (SVR12). We collected data on on-treatment adverse events (AEs), severe AEs, and laboratory abnormalities.
RESULTS: The average baseline eGFR (CKD-EPI equation) was 70.06±20.1mL/min/1.72m2; the most common genotype was HCV 1b (n=93, 51%). Advanced liver scarring was found in 58 (46%) patients by transient elastography. Five regimens were adopted: elbasvir/grazoprevir (n=5), glecaprevir/pibrentasvir (n=4), ritonavir-boosted paritaprevir/ombitasvir/dasabuvir (PrOD) regimen (n=40), simeprevir±daclatasvir (n=2), and sofosbuvir-based combinations (n=147). The SVR12 rate was 95.4% (95% CI, 93.8%; 96.8%). There were nine virological failures - eight being relapsers. Adverse events occurred in 30% (51/168) of patients, and were managed clinically without discontinuation of therapy or hospitalization. One of the most common AEs was anaemia (n=12), which required discontinuation or dose reduction of ribavirin in some cases (n=6); deterioration of kidney function occurred in three (1.7%).
CONCLUSIONS: All-oral, interferon-free therapy with DAAs for chronic HCV in mild-to-moderate CKD was effective and well-tolerated in a 'real-world' clinical setting. Studies are in progress to address whether sustained viral response translates into better survival in this population.
