Evaluation of various prediction equations to estimate GFR is rare in our population. The aim of this study was to compare GFR estimated by various prediction equations with GFR by creatinine clearance (GFRer) in Bangladeshi population. Serum creatinine and 24 hours urinary creatinine concentrations were measured in 216 adult Bangladeshi subjects (100 males and 116 females). Creatinine clearance rate was calculated and adjusted for body surface area to obtain GFRcr. GFR was also calculated by CKD-EPI, MDRD4, Cockcroft-Gault, Jelliffe, Mawer, Bjornsson, Gates, Apollo-Chennai and Mayo Clinic prediction equations and compared with GFRcr. Results were expressed as mean + SD and compared by two-tailed paired t-test, precision (r2) and receiver-operating characteristic curve. Mean ± SD of age of the total subjects was 57.15 ±10.96 years. The mean GFILzr was 42.41 ± 22.95 mL/min/1.73m2. Estimated GFR (eGFR) by CKD-EPI, MDRD4, Cockcroft-Gault, Jelliffc 1, Jelliffe 2, Mawer, Bjornsson, Gates, Apollo-Chennai and Mayo Clinic prediction equations were 8.19 ± 13.80, 5.30 ±13.61, 11.54 ± 16.86, 8.66± 18.64, 17.25 ± 19.98, 10.86 ± 22.48, 14.60 ± 17.92, 12.18 ± 16.42, 39.86 ± 21.96 and 20.47 ± 20.49 mL/min/1.73m2 higher than GFR, (P 〈 0.001). The precision (r2) of eGFRs were 0.7114, 0.6924, 0.6431, 0.4802, 0.5048, 0.5921, 0.6286, 0.6158, 0.1635, and 0.5586 for CKD-EPI, MDRD4, Cockcroft-Gault, Jelliffe 1, Jelliffe 2, Mawer, Bjornsson, Gates, Apollo-Chennai and Mayo Clinic prediction equations, respectively. The area under receiver-operating characteristic curve was the lowest for MDRD4 equation. This study revealed that GFR estimated by standardized MDRD4 variables equation is closer to creatinine clearance rate in the study population.展开更多

In addition, this scheme is applied in clinical studies evaluating the risks of CKD and the efficacy of various interventions directed towards improving its course. Disagreements between creatinine-based and cystatin-based e GFR values and between e GFR values and measured GFR have been reported in various cohorts. These disagreements are the consequence of variations in the rate of production and in factors, other than GFR, affecting the rate of removal of creatinine and cystatin C. The disagreements create limitations for all e GFR formulas developed so far. The main limitations are low sensitivity in detecting early CKD in several subjects, e.g., those with hyperfiltration, and poor prediction of the course of CKD. Research efforts in CKD are currently directed towards identification of biomarkers that are better indices of GFR than the current biomarkers and,particularly, biomarkers of early renal tissue injury.展开更多
