Treatment of hemodialysis patients infected with two or three hepatitis C virus (HCV) genotypes (Gt) with interferon-free regimens has not been possible until the recent introduction of pan-genotypic next generation therapy. The main reason is that sofosbuvir (SOF)-containing regimens are contraindicated in patients with low glomerular filtration rate. We describe here a case of a chronic HCV infection in a patient with end-stage renal disease, successfully treated with glecaprevir/pibrentasvir (GLE/PIB). Limited published data are available regarding the efficacy of antiviral therapy in patients with rare HCV recombinant Gt 2k/1b. We were not able to identify any reports describing treatment of hemodialysis patients with this recombinant type of HCV. We present a 57-year-old patient with autosomal-dominant polycystic kidney disease with liver involvement with end-stage of kidney disease. He was infected with HCV Gt 2k/1b variant after initiation of hemodialysis. This subtype appeared in Russia (Soviet Union that times) as a result of high frequency of virus mutations, and actually is widely spread in some states of the post-Soviet space, as well as in the countries with intensive migration from Russia and other former Soviet republics. In this particular case, we observed a tendency to a rapid progression of liver fibrosis despite mild clinical activity of chronic hepatitis C. A 12-week course of GLE/PIB allowed achieving sustained virologic response (SVR) and was well tolerated.
