Association of uric acid and uric acid to creatinine ratio with chronic kidney disease in hypertensive patients.

Background: Recent studies have shown that the serum uric acid/creatinine ratio (SUA/SCr) is a better predictor of chronic kidney disease (CKD) than serum uric acid (SUA) isolated. The aim of the present study was to evaluate the association of isolated SUA and the SUA/SCr with CKD in hypertensive patients.

Methods: Cross-sectional study conducted with hypertensive patients followed-up by the Primary Health Care Service (PHC).
