CST3 and chronic kidney disease: In a recent analysis Lucas G et al evaluated the association of eGFR, estimated by three different equations (Cockcroft/Gault, MDRD and CKD-Epi with and withous the inclusion of cystatin C besides creatinine), with clinical events in HIV-infected patients in the SMART study and found that eGFR estimates using plasma cystatin C had stronger associations with mortality, cardiovascular events and opportunistic diseases than eGFR based on plasma creatinine [21].
