Webserum cystatin C level, and, for this reason, increases in cystatin C are detectable much earlier in the course of CKD when levels of creatinine are still in the normal range.11 This enables more timely diagnosis and initiation of treatment, allowing the optimal benefits of therapy for the patient to be realized.

WebThis version does not include race, as do the 2009 and 2012 CKD-EPI creatinine and creatinine-cystatin C equations. See here for more on our approach to addressing race and bias on MDCalc. With the 2024 equation, for the same creatinine value, the 2024 equation will estimate a lower GFR for Black patients and a higher GFR for non-Black patients.

WebThe use of cystatin C-based GFR-estimating equations, alone or in conjunction with creatinine-based GFR-estimating equations, is therefore highly recommended to eliminate the use of race coefficients in estimating GFR. Although sex is a more biology-oriented parameter than race, sex terms may in some cases be controversial, involving self ... WebThe cystatins are a family of cysteine protease inhibitors which share a sequence homology and a common tertiary structure of an alpha helix lying on top of an anti-parallel beta sheet. The family is subdivided as described below. Cystatins show similarity to fetuins, kininogens, histidine -rich glycoproteins and cystatin-related proteins.
