Your kidneys filter creatinine from the blood into the urine and reabsorb almost none of it. The serum creatinine is then used to estimate the GFR (eGFR) based on a formula. Why Creatinine Tests Are Done Doctors use serum creatinine and eGFR to check how well your kidneys work. As kidney...
Random-effect linear regression model was used to assess changes in eGFRcre over 96 weeks from starting ART, and from switching to DTG. Results: At study entry, 20 participants (9.3%) had eGFRcre < 90 ml/min/1.73 m2. During EFV-based ART, an additional 17 (8%) developed eGFRcre < ...
Logistic regression models were used to estimate the association between baseline characteristics and having a cystatin C–based eGFR (eGFRcys) that was more than 30% lower than the serum creatinine–based eGFR (eGFRcr) or an eGFRcys that was more than 30% higher than the eGFRcr. AOR indicat...
Recently, several other indicators based on serum creatinine and cystatin C were reported. In the studies by Yang et al. [36] and Fu et al. [37], the new version of SI, serum creatinine × cystatin C-based eGFR, also showed its potential to screen for low muscle mass or sarcopenia ...
All creatinine-based eGFR equations overestimated GFR (p < 0.01 for each creatinine based eGFR equation). However, eGFR by CKD-EPICys was not significantly different from mGFR (p = 0.38). The CKD-EPICys exhibited lowest bias [mean bias: −3.53 ± 14.70 ml/min/1.73m2 (95% CI: -0.608...
The National Kidney Foundation recently endorsed the refit Chronic Kidney Disease Collaboration (CKD-EPI) equation for estimated glomerular filtration rate (eGFR) using creatinine, age and sex [2021 eGFRCr(AS)] without a coefficient for race. We evaluated the impact of adopting the 2021 eGFRCr(AS...
Two equations based on creatinine values were correlated (MDRD and MCQE); they were not correlated with CG. 29 level athletes, characterized from a high release of creatinine. The use of equations should be accurately evaluated: the CG equation can overestimate the eGFR, the MDRD and MCQE ...
Additionally, the agreement between the KDIGO CKD-risk score classification based on eGFR and semi-quantitative and quantitative ACR indicates that the semi-quantitative results obtained with the test strip are reliable. However, reporting the category in which the patient is classified has limited ...
Cystatin C is less influenced thancreatinineby race, so GFR estimates based on cystatin C alone (eGFRcys) include only age and sex, and not race. This allows GFR to be estimated without specification of race. This can be quite helpful in mixed-race populations. However, eGFRcys is not mor...
Then, we compared the risks of eMACEs and renal events among the 20 categories overall for eGFR and proteinuria, using the group with the greatest eGFR (≥ 90 mL/min/1.73 m2) and lowest proteinuria (< 300 mg/g) as the reference2. We assessed the independent associations of ...
