Uric acid and glucose metabolism in uncomplicated libyan diabetic patients
364 Views Short Communication
Uric acid has increasingly been associated with insulin resistance, hyperinsulinemia, and type 2 diabetes mellitus. Diabetic patients who are hyperuricemic have a risk of developing diabetic complications. Pathogenesis of uric acid may decrease nitric oxide bioavailability in vascular smooth muscle, endothelial cells and direct scavenging of nitric oxide by uric acid. A decrease in endothelial nitric oxide production by uric acid has also been associated with endothelial dysfunction and insulin resistance. This study aims is to determine the relationship between uric acid and glucose levels in patients with type 2 diabetes mellitus. The study included 161 Libyan patients (67 males and 94 females) diagnosed with type 2 diabetes mellitus. Both levels of serum uric acid and hemoglobin A1c (HbA1c) were determined. The patients were divided into two groups. The controllable diabetic group with HbA1c of less than 06.0% and the uncontrollable diabetic group with HbA1c of more than 06.0%. Patients who are suffering from type 2 diabetes mellitus without complications were included whereas patients with smoking, alcoholism, nephrotic disease, malignancy, hepatitis, and renal failure or kidney disease were excluded. The mean and standard deviation of uric acid, HbA1c and Pearson correlation coefficient test were considered. In the controllable diabetic group, serum uric acid mean was found to be 4.807 ± 1.39 and HbA1c was found to be 5.032 ± 1.39. In the uncontrollable diabetic group, serum uric acid was 4.897 ± 1.66 and HbA1c was 8.396 ± 1.65. Uric acid level has significantly been correlated with HBA1C in controlled and uncontrolled diabetic patients (p < 0.05). In addition, the uric acid level was found to be higher in uncontrolled diabetic group than that in the controlled group (p < 0.05). A possible relationship between serum uric acid and incidence of type 2 diabetes mellitus was noted. Thus, uric acid can be used as a potential biomarker to indicate impaired glucose metabolism.
