(HealthDay News) — Sofosbuvir-based treatment appears to guarantee renal safety for patients with chronic hepatitis C virus over one year of follow-up, according to a study published online in the Journal of Clinical Pharmacy and Therapeutics.
Thalia Medeiros, from the Universidade Federal Fluminense in Niterói, Brazil, and colleagues evaluated renal biomarkers among 94 chronic hepatitis C patients treated with sofosbuvir therapy. Urine samples were collected at the end of therapy, after 12 weeks sustained virological response, and one year post-treatment.
The researchers found that 98.9% of patients reached sustained virological response. In patients with glomerular filtration rate (GFR) ≥45 mL/min/1.73 m² there was significant improvement in renal biomarkers, as indicated by a progressive increase in mean GFR values until one year. There was no evidence of tubular dysfunction. There was no change in renal biomarkers among patients with baseline GFR <45 mL/min/1.73 m².
“In a ‘real-life experience’ of a Brazilian center, sofosbuvir therapy appears to guarantee renal safety for patients with chronic hepatitis C followed until one year after treatment,” the authors write.
