Prevalence of chronic kidney disease in a city of southeast Brazil

Abstract Introduction: Chronic kidney disease (CKD) is a worldwide public health alarming problem. Objective: This study investigated the estimated prevalence of kidney disease in diabetic and high-risk hypertensive patients to cardiovascular disease registered in Hiperdia program of a city of southeast of Brazil. Methods: It is a transversal study conducted between May 2014 and August 2015. The study has included randomly 243 diabetic and high-risk hypertensive patients to cardiovascular disease which were originally referred from primary health care to the Hiperdia. CKD was classified based on cause, Glomerular Filtration Rate (GFR), and albumin creatinine ratio (ACR). Were considered abnormalities GFR < 60 mL/min/1.73m2 and/or ACR ≥ 30 mg/g. Results: Of the 243 patients, 89 (36.6%) showed alterations in renal function markers in the first collection. Of these, 60 patients had a GFR < 60 mL/min/1.73 m2 and 25 the GFR was < 45 mL/min/1.73 m2. The ACR was ≥ 30 mg/g in 43 patients and eight of the values were > 1000 mg/g. In 15 patients studied were found both changes. Of the 89 participants with abnormal renal function markers in the first collection 63 held the second test and 42 kept the changes being diagnosed with CKD. None of these patients had prior knowledge of the diagnosis of kidney disease and the need for consultation with the nephrologist. Conclusion: The prevalence of CKD was 17.3% of disease in the population studied.
