The association of serum uric acid level with metabolic risk factors in patients with type 2 diabetes and their relation to eGFR status

Abstract

BackgroundThe importance of uric acid has been increasingly appreciated because of its association with the development of diabetes mellitus and related diseases, and with the increasing incidence of diabetes, studying the impact of hyperuricemia in patients with diabetes type 2 is necessary. So we aimed to measure serum uric acid (SUA) levels in patients with diabetes type 2 and to assess the relation between the estimated glomerular filtration rate (eGFR) and the SUA in patients with type 2 diabetes (T2DM).Subjects and methodsThis study is a cross-sectional conducted on 142 adult patients who attended the Outpatients Diabetes Clinic and Endocrinology Center in the Department of Internal Medicine, Assiut University Hospitals, in the period from the 1st of November 2021 up to October 2022. We measured serum uric acid level, serum creatinine, cholesterol, low- and high-density lipoproteins, triglycerides, and eGFR.ResultsOverall, 142 patients were enrolled in the study; all patients had type 2 diabetes. The mean age of the participants was 61.08 ± 9.73 years. Based on SUA level, 46 (32.4%) patients had normal SUA and 96 (67.6%) patients had high SUA. Sixty-nine (48.6%) patients had normal eGFR and 73 (51.4%) patients had reduced eGFR. We found that serum uric acid had a positive significant correlation with the number of metabolic syndrome criteria, cholesterol, low-density lipoproteins, and triglycerides. Meanwhile, it had a negative significant correlation with eGFR and high-density lipoproteins.ConclusionSerum uric acid was strongly associated with metabolic syndrome components and reduced eGFR in patients with T2DM.
