Prevalence and Determinants of Chronic Kidney Disease Among Hypertensive Cameroonians According to Three Common Estimators of the Glomerular Filtration Rate.

Hypertension is a risk factor for renal diseases, which, in turn, are precursors of hypertension. The authors assessed the prevalence and determinants of chronic kidney disease (CKD) among 336 hypertensive adult Cameroonians (mean age, 60.9±11.3 years; 63.4% women) at Yaoundé. Any participant with an estimated glomerular filtration rate <60 mL/min/1.73 m(2) regardless of the equation used (Cockcroft-Gault [CG], Modification of Diet in Renal Disease [MDRD], and Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) and/or dipstick proteinuria was reviewed 3 months later. Participants presented a high prevalence of diabetes (18.5%), dyslipidemia (17.6%), gout/hyperuricemia (10.7%), overweight/obesity (68.8%), self-medication (37.5%), and alcohol consumption (33.3%). Hypertension was uncontrolled in 265 patients (78.9%). The prevalence of CKD was 49.7%, 50.0%, and 52.1% according to MDRD, CKD-EPI, and CG equations, respectively. Advanced age, adiposity, and severity of hypertension were determinants of CKD. Nearly half of the hypertensive patients had CKD regardless of the estimators used, predicted by well-known risk factors. ©2016 Wiley Periodicals, Inc.
