A Study of Association of C-Peptide with Diabetic Peripheral Neuropathy
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 4
Abstract
Background: The aim of our study was to evaluate the relationship between C-peptide and DPN in community-based patients with type 2 diabetes. Methods: In total, 220 consecutive type 2 diabetic patients treated by our regional medical consortium were enrolled. DPN was assessed by clinical symptoms, signs, and electromyography. Results: Fasting C-peptide, 2-h postprandial C-peptide and ΔC-peptide (i.e., 2-h postprandial C-peptide minus the fasting C-peptide) serum concentrations in the non-DPN group were significantly higher than those in the clinical DPN group (all P ≤ 0.040) and the confirmed DPN group (all P < 0.002). The three C-peptide parameters were independently associated with DPN (all P < 0.05) after adjusting for age, sex, diabetes duration, smoking status, systolic pressure, body mass index, angiotensin-converting enzyme inhibitors/ angiotensin receptor blocker use, fasting plasma glucose, HbA1c, triglyceride and estimated glomerular filtration rate. Compared with the ΔC-peptide quartile 1 (reference), patients in quartile 3 (odds ratio [OR], 0.110; 95% confidence interval [CI] 0.026–0.466; P = 0.003) and quartile 4 (OR, 0.012; 95% CI 0.026– 0.559; P = 0.007) had a lower risk of DPN after adjusting for the confounders. Conclusion: C-peptide was negatively associated with DPN in community-based type 2 diabetic patients.
