Association between hyperuricemia and glycated hemoglobin in type 2 diabetes at the District Hospital of Dschang

Abstract

Introduction: given the difficulty to obtain glycemic control in type 2 diabetes, the exploration of others pathophysiological hypotheses could improve the understanding of this phenomenon. We conducted this study to search for an association between uric acid and uncontrolled diabetes.

Methods: it was a cross-sectional study in a population of type 2 diabetes with normal postprandial and fast blood sugar for the last three months at the District Hospital of Dschang. Chi square test were used to analyzed categorical variables and Pearson correlation coefficient to evaluate the relationship between uric acid level and HbA1c. Means were compared using Kruskal-Wallis´s or Student´s test.

Results: our study of 80 patients found that, female sex and central obesity were risk factors for hyperuricemia. Prevalence of hyperuricemia and uncontrolled diabetes was respectively 27.5% and 33.8%. The proportion of women with hyperuricemia was significantly higher than that of men (59.1% versus 40.9%, p=0.021) and this inequality of proportion was more marked particularly after 45 years (40% versus 18.8%, p=0.022). Hyperuricemia was not significantly associated to uncontrolled diabetes (OR=2.01 IC (0.73-5.52), p=0.095). Serum uric acid was positively and significantly correlated to glycated hemoglobin (r=0.318, p=0.002) and hyperuricemia was significantly correlated to uncontrolled diabetes (r=0.712, p=0.035). The mean of glycated hemoglobin is abnormal (7.14%) when uric acid level is around 5.75 mg/dl without sex distinction.

Conclusion: these results suggest that the rate of glycated hemoglobin is associated to serum uric acid variations during type 2 diabetes.
