Abstract

Diabetic peripheral neuropathy (DPN) is a microvascular complication of diabetes mellitus. The aim of this meta-analysis was to evaluate the effects of methylenetetrahydrofolate reductase (MTHFR) 677 C>T and ACE I/D polymorphisms in the development of DPN. We systematically reviewed published studies on MTHFR 677 C>T and ACE I/D polymorphisms and DPN found in various types of electronic databases. Strengthening the Reporting of Observational studies in Epidemiology (STROBE) quality score systems were used to determine the quality of the articles selected for inclusion. Odds ratios (ORs) and its corresponding 95 % confidence interval (95 % CI) were calculated. We used STATA statistical software (version 12.0, Stata Corporation, College Station, TX, USA) to deal with statistical data. Our results indicated an association of ACE D>I mutation (OR = 1.43, 95 % CI 1.12-1.83, P = 0.004) and MTHFR 677 C>T mutation (OR = 1.43, 95 % CI 1.08-1.90, P = 0.014) with DPN under the allele model, and similar results were also found under the dominant model (all P < 0.05). Subgroup analysis by country indicated that the MTHFR 677 C>T polymorphism may be the main risk factor for DPN in Turkey under four genetic models. ACE D>I mutation was correlated with DPN in Japanese and Pakistani populations in the majority of groups. The relationships of MTHFR 677 C>T and ACE I/D polymorphisms with DPN patients presented in this meta-analyses support the view that the MTHFR and ACE genes might play an important role in the development of DPN.
