Introduction: Hyperuricemia is considered to be an independent risk factor for renal dysfunction in diabetics and
albuminuria can be used as a surrogate marker of early diabetic nephropathy. We studied the correlation between
hyperuricemia and albuminuria in type 2 diabetes mellitus patients. Materials and Methods: In a cross-sectional
study of 90 patients (45 men and 45 women) with type 2 diabetes mellitus, serum uric acid, albuminuria and
urinary albumin-creatinine ratio were determined. Other parameters namely blood pressure, body mass index,
serum cholesterol, serum triglycerides, glomerular filtration rate and fasting blood glucose were also assessed.
Results: The mean age of the study population was 61.49 ± 11.4 years. Serum uric acid levels for
normoalbuminuric, microalbuminuric, and macroalbuminuric patients were 5.01 ± 1.46, 6.8 ± 1.16 and 8.58 ±
0.42mg/dL respectively. Serum uric acid level had a significant positive correlation with urinary albumin creatinine
ratio even after adjustment for age, sex, body mass index, insulin use, smoking, diabetes duration, systolic blood
pressure, diastolic blood pressure, fasting plasma glucose, serum cholesterol, triglycerides, and calculated
creatinine clearance. There was also significant association between hyperuricemia and serum triglyceride, fasting
blood glucose, cholesterol levels, glomerular filtration rate, serum creatinine levels, age, duration of diabetes
mellitus, and body mass index. Conclusions: We demonstrated that serum uric acid levels have a significant
independent positive correlation with albuminuria.
Keywords: Type 2 diabetes, hyperuricemia, diabetic nephropathy, albuminuria.
