ASSESSMENT OF THE CORRELATION OF BIOCHEMISTRY TESTS AND BIOLOGICAL PARAMETERS TO ESTIMATED GLOMERULAR FILTRATION RATE IN CHRONIC RENAL FAILURE SUBJECTS
Main Article Content
Abstract
Objectives: To investigate the correlation of biochemical tests and biological parameters with the glomerular filtration rate established by the formulas Cockcroft - Gault, MDRD, CKD - EPI 2009, 24-hour creatinine clearance on subjects with impaired renal function. chronic kidney. Methods: Cross-sectional study based on 44 Vietnamese citizens, aged 18 years or above who have chronic kidney disease. Results: Age has a low negative correlation with Cockcroft – Gault (r=-0,39); glucose has low correlation with Cockcroft – Gault (r=-0,37), MDRD (r=-0,32), CKD – EPI 2009 (r=-0,34); creatinine is highly inversely correlated with Cockcroft – Gault (r=-0,82), MDRD (r=-0,92), CKD – EPI 2009 (r=-0,90), CrCl 24h (r=0,71); urea is highly inversely correlated with Cockcroft – Gault (r=-0,63), MDRD (r=-0,73), CKD – EPI 2009 (r=-0,73), CrCl 24h (r=-0,48); Gender, BMI, blood pressure, albumin levels, protein levels and uric acid levels were not correlated with eGFR calculated by the formulas. Besides, CrCl 24h has a high positive correlation with Cockcroft – Gault (r=0,72), MDRD (0,77), CKD – EPI 2009 (0,78). The eGFR calculated by MDRD had the lowest deviation with 24h CrCl (deviation -1.44). Conclusions: There is a relationship between age, glucose, urea, and creatinine, CrCl 24h with established glomerular filtration rate; MDRD formula gives the best estimate with CrCl 24h.
