Association of ACE polymorphism and diabetic nephropathy susceptibility.

ABSTRACT: AIM:The study was aimed to analyze whether ACE rs267604983 polymorphism was related to the onset of diabetic nephropathy (DN). METHODS:80 DN patients and 78 healthy controls were enrolled in the study. The differences of age, sex, body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) between two groups were analyzed. The genotyping of ACE rs267604983 was conducted by the technology of PCR-HRM. Odds ratio (ORs) with 95% CI were used to evaluate the relationship of ACE rs267604983 with DN susceptibility. RESULTS:The AA genotype of ACE rs267604983 was remarkably associated with the risk for DN (OR = 2.90, 95% CI = 1.12-7.51). In addition, for the A allele carriers, the risk for DN increased 1.87 fold (OR = 1.87, 95% CI = 1.16-3.01). The subgroup analysis showed that the AA genotype was found higher in normal albuminuria group than other groups (P = 0.006), while AG genotype was higher in macro albuminuria group (P = 0.036). CONCLUSION:ACE rs267604983 polymorphism is associated with the risk of DN. AA genotype and A allele may increase the risk for DN. Furthermore, AA and AG genotypes may have effects on the subgroups of DN.

Project description:BackgroundStudies evaluating the association between monocyte chemoattractant protein-1 (MCP-1) -2518 A > G (rs1024611) polymorphism and type 2 diabetes mellitus (T2DM) and diabetic nephropathy (DN) are contradictory. The present study aims to provide a comprehensive assessment and more reliable estimation of the relationship between the MCP-1 rs1024611 polymorphism and T2DM and DN risk.MethodsEligible articles were retrieved from the PubMed, Web of Science, EMBASE, Cochrane, and China National Knowledge Infrastructure databases. The effect summary odds ratios (ORs) and 95% confidence intervals (CIs) were obtained to calculate the summary effect size. Heterogeneity was analyzed by subgroup analysis and meta-regression. Publication bias was tested using funnel plots and Egger's test.ResultsIn total, sixteen studies were included. Thirteen studies involving 2,363 patients with T2DM and 4,650 healthy controls found no significant association between the MCP-1 rs1024611 polymorphism and T2DM in the overall population. Ethnicity stratification found an association between the GG + GA genotype and decreased T2DM risk in Caucasians (OR = 0.79, 95% CI: 0.66-0.93, P = 0.006; PQ = 0.372). No significant risks were found in the Asian population for any genetic models. Seven studies found an association between the GG + GA genotype and DN risk in the Asian population (OR = 1.37, 95% CI: 1.11-1.71, P = 0.004, PQ = 0.222). No significant risks were found in the Caucasian population with any genetic models. There were no statistically significant differences in genotype distribution between patients with T2DM and DN in Asians or Caucasians. Meta-regression revealed that genotyping method was a major driver of heterogeneity in five genetic models (GG + GA vs. AA: P = 0.032; GG vs. GA + AA: P = 0.028; GG vs. AA: P = 0.035; GG vs. GA: P = 0.041; G vs. A: P = 0.041).ConclusionThe MCP-1 rs1024611 polymorphism is associated with susceptibility to T2DM in Caucasians and DN in Asians. Larger, well-designed cohort studies are needed in the future to verify this association.
