Resumo: Chronic kidney disease (CKD) is a global public health problem. The elderly have progressive decrease of renal function, and those with hypertension and diabetes are at increased risk of kidney damage. These chronic diseases are common to the elderly and promote renal injury. This study aimed to identify the best method to assess early glomerular filtration (GF) in elderly subjects. Formulas based on serum creatinine and creatinine clearance of 24 hours were compared with the formula based on serum cystatin C chosen as gold standard. We conducted an observational, analytical, cross-sectional design of the glomerular filtration rate and the development of kidney disease, through results obtained in clinical evaluation, and biochemistry and urinalysis laboratory tests. Participants were 180 patients of both sexes, aged over 60 years, from the Centro de Atenção Integrada da Melhor Idade [Center for Integrated Management of the Elderly], in the city of Manaus, State of Amazonas, Brazil. Scatter plots were constructed by calculating the correlation coefficient, as well as Bland Altman plotted diagrams and ROC curves. The average age of the elderly participants was 67 years; 68.8% were female and 31.1% male; 43.5% had hypertension; 19%, chronic renal failure; and 38.83%, diabetes mellitus. By observing the regression equation, when the CKD-epiCys was zero, creatinine clearance (CrCl) was 62.07 ml/min/1.73m2, which means overestimation of the real FG rate. The average assessed by CrCl. and CKD-epiCys was 28.8 ml/min/1,73m2, a value above zero, which would be ideal. This shows that CrCl. overestimates FR assessed by CKD-epiCys. The ROC curve for CrCl to discriminate the presence of FG <60 ml / min measured by the standard was 0.65, with 95% confidence interval from 0.56 to 0.76 (p = 0.006). The CrCl had statistically significant predictive power concerning the presence of KD. The regression was assessed by ...
