“…Most of the studies that examined this issue were conducted in patients with moderate CKD. Gonzalez-Parra and colleagues 110 observed a significant mean decrease in GFR of 9 ml/min per 1.73 m 2 in 35 patients treated with a sofosbuvirbased regimen with a baseline GFR of 30 to 60 ml/min per 1.73 m 2 , whereas no significant decline in GFR occurred in 8 patients treated with the PrOD regimen. Rosenblatt et al 111 also reported that in a series of 90 patients, a baseline CrCl < 60 ml/min predicted a decline in kidney function with sofosbuvir therapy.…”
