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±28.3ml/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.
