The Relationship Between Diabetic Neuropathy and Uric Acid/High-Density Lipoprotein Ratio in Patients With Type-2 Diabetes Mellitus

Background: We aimed to investigate whether there was a relationship between diabetic peripheral distal neuropathy (DPDN), one of the most common chronic complications in patients with type 2 diabetes mellitus (T2DM), and the uric acid/HDL ratio, which can be used as an indicator of poor metabolic status. Methodology: The study consisted of a total of 150 subjects, including 50 patients with T2DM (group 1) who were determined to have diabetic peripheral distal neuropathy with electroneuromyography (ENMG), 50 patients with T2DM who were determined to not have DPDN in their ENMG (group 2), and 50 healthy individuals (group 3). Participants’ serum fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), uric acid, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride levels were analyzed. The uric acid/HDL-C ratio (UHR) was calculated. The relationship between UHR and other parameters was evaluated in all three groups. Results: Patients with T2DM who had diabetic neuropathy (group 1), did not have diabetic neuropathy (group 2), and healthy subjects (group 3) were similar in terms of age and gender (p=0.066, p=0.185). Groups 1 and 2 were similar in terms of the duration of diabetes and FBG values (p=0.825, p=0.572), but these values were lower in group 3 than in groups 1 and 2 (p<0.05). HbA1c did not differ significantly between groups 1 and 2 (p=0.607). Creatinine levels were similar in the three groups. Uric acid levels were significantly higher in group 1 than in group 2 (p=0.040), but there was no significant difference between groups 1 and 3 or between groups 2 and 3 (p>0.05). UHR was significantly lower in group 1 than in groups 2 and 3 (p<0.001), but no significant difference was found between groups 2 and 3. Conclusion: In our study, we found that the UHR level of the group with diabetic neuropathy was statistically significant compared to the levels of the other two groups. However, no significant difference was found between the patients with diabetes who did not have neuropathy and the healthy group. Based on the findings of our study, we can say that the UHR level is a predictor of the microvascular complications of diabetes.
