Cystatin C-based equations in renal transplantation: moving toward a better glomerular filtration rate prediction?

Abstract : Creatinine-based glomerular filtration rate (GFR) estimators perform poorly in renal transplant recipients. Cystatin C might be a better alternative to serum creatinine in assessing renal graft function. We compared several cystatin C-based equations with the modification diet renal disease (MDRD) equation in 120 adult renal transplant recipients for whom the GFR was measured by the gold standard inulin clearance. Mean inulin-measured GFR was 52.6 mL/min/1.73 m (range, 13-119). The Hoek, Rule, Le Bricon, and Filler cystatin C-based formulas showed significantly better performances (accuracy 30% of 82%, 81%, 78%, and 71%), than the MDRD equation (58%, Mac Nemar test, P<0.01). Sensitivity to detect a GFR below 60 mL/min/1.73 m was significantly higher for the Hoek and the Rule equations (0.95, 95% CI 0.91-1) than for the MDRD equation (0.76, 95% CI 0.67-0.85). These data confirm that cystatin C as a GFR marker offers significant advantages over creatinine in renal transplantation.
