ABSTRACT
Objective To explore the interaction of angiotensin converting enzyme (ACE) insertion/deletion(I/D) polymorphism(rs1799752)with diabetic kidney disease (DKD) development as well as its interaction with smoking and obesity in Chinese type 2 diabetic mellitus (T2DM) using the improved experiment method. Methods From June 2016 to March 2018, 300 T2DM patients with DKD [DKD(+)] and 300 T2DM patients without DKD[DKD(-)] were selected from China-Japan Friendship Hospital. The improved Triple Primer Method that combined PCR with capillary electrophoresis was established in this study to detect the ACE genotype. The relevant clinical data as well as the frequencies of genotype and allele of ACE gene I/D polymorphism between two groups were statistically analyzed. Patients were further grouped based on smoking status and obesity for multivariate regression. Results Frequency of the DD genotype and D allele were significantly higher in DKD(+) group than in DKD(-) group [DD genotype15.0% (45 cases) vs 7.3%(22 cases),χ2=10.8, P=0.004;D allele36.5%(219 cases) vs 28.0%(168 cases),χ2=9.92, P=0.02]. Multivariate logistic regression analysis found that D allele of rs1799752 was associated with a significantly higher risk of DKD in both recessive model(OR=1.45, 95%CI1.06-2.00, P=0.022 after adjustments) and additive model(OR=1.41, 95%CI1.04-1.90, P=0.025 after adjustments). In the smoker group and the obese group, D allele showed significant relationship with DKD incidence (P<0.05 after adjustments) in both recessive model and dominant model. No such relationships were observed in non-smoker group and non-obese group (P>0.05). Conclusions I/D polymorphism of ACE gene is associated with the incidence of DKD in T2DM patients. DD genotype of the ACE gene is the risk factor for T2DM patients with DKD. D allele may increase DKD incidence in the presence of smoking and obesity.
