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. 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 ...
WebSep 11, 2009 · The mean cystatin C in the largest equation study, conducted by the CKD-EPI group, was 1.8 (SD = 0.8) mg/L (17), whereas the mean cystatin C level in the present study was 0.95 (0.30) mg/L. Application of a regression equation outside of the range of cystatin C values in which it was developed may introduce bias into the estimates; … WebFeb 17, 2024 · Current practice guidelines for CKD recommend measuring cystatin C when precision of eGFR is required and suggest adding cystatin C for confirmatory testing in situations when creatinine is less accurate, such as in persons who may underproduce creatinine because they are frail. 5,6,17 As efforts advance to improve CKD detection …
