Telaprevir decreases estimated glomerular filtration rate in HIV-hepatitis C virus coinfected patients.

We investigated kidney function outcome in 24 chronic hepatitis C genotype 1 patients coinfected with HIV receiving telaprevir in a single tertiary care hospital in Spain. A statistically significant median (interquartile range) decrease in estimated glomerular filtration rate (eGFR, ml/min/1.73 m) relative to baseline [93.6 (73.0-109.0)] was seen at weeks 4 [86.5 (34.0-112.0), P = 0.014], 8 [90.0 (49.0-111.0), P = 0.026] and 12 [89.5 (54.0-113.0), P = 0.017]. These changes reversed after telaprevir discontinuation. Patients presenting an eGFR decrease had a higher risk of haematological toxicity.
