ABSTRACT
The prevalence of chronic renal failure (CRF) in 460 patients with diabetes mellitus attending the diabetic outpatient clinic at the University Hospital of the West Indies in Jamaica was determined from a review of medical records. The prevalence of CRF was 10 (39/386) in the diabetic clinic population. Significant positive associations with CRF were found with male gender (20/98, 20 vs 19/287, 7; odds ratio (OR), 3.24; p = 0.001); age 60 years and older (22/162; 14 vs 17/221, 8; OR, 2.01; p = 0.04); fasting blood glucose concentrations exceeding 8.0 mmol/L (22/162, 13 vs 12/182, 7; OR, 2.08; p = 0.05); the presence of significant proteinuria as a marker for outcome (13/39, 33 vs 48/346, 14; OR, 3.60; p = 0.02) and peripheral vascular disease (6/20, 30 vs 139/386, 10; OR, 4.75; p = 0.005). The prevalence of CRF did not differ significantly between patients with Type 1 and Type 2 diabetes mellitus. Also, the presence of CRF was not significantly associated with duration of diabetes mellitus, type of hypoglycaemic agents used, or history of hypertension. However, the presence of persistent proteinuria was significantly associated with duration of diabetes mellitus exceeding five years (46/255, 17 vs 11/149, 7; OR, 2.52; p = 0.005) and a history of hypertension (41/235, 17 vs 20/198, 10; OR, 1.88; p = 0.03) but not with age or gender. This study emphasizes the need to evaluate patients with diabetes mellitus for renal impairment so that intervention strategies may be adopted early to delay progression to endstage renal disease
