Treatment of chronic hepatitis C in patients with chronic kidney disease with Sofosbuvir-basead regimes

Background: To analyze the effectiveness and the safety of Sofosbuvir-based regimens to treat patients with chronic hepatitis C virus (HCV) infection and chronic kidney disease (CKD). Methods: A retrospective, observational study in patients with chronic HCV infection and CKD treated with Sofosbuvir-based regimens was performed. Liver fibrosis, comorbidities, HCV genotype and sustained virological resposnse (SVR) at 12th week post-treatment were evaluated. Kidney function was accessed by serum creatinine and glomerular filtration rate (GFR). The assumed level of significance was 5 %. Results: Thirty-five patients were treated. The mean age was 52.1 +/- 10.9 years, 19 (54.3 %) were women, 32 (91.4 %) were already kidney transplanted and 3 (8.6 %) were on hemodialysis. The SVR by intention to treat was 88.6 %. The mean GFR was 65.8 +/- 28.6 and 63.7 +/- 28.3 ml/min pre- and post-treatment respectively (p > 0.05). Treatment was interrupted in 1 (2.85 %) patient due to anemia and in 2 (5.7 %) due to loss of kidney function. Conclusion: Sofosbuvir-based regimens are effective to treat HCV in patients with CKD. In patients with mild CKD this type of therapy seems to be safe. (C) 2020 Sociedade Brasileira de Infectologia. Published by Elsevier Espana, S.L.U.
