Association of polymorphisms of angiotensin I converting enzyme 2 with retinopathy in type 2 diabetes mellitus among Chinese individuals.

ABSTRACT: To examine the association of Angiotensin I converting enzyme 2 (ACE2) gene polymorphisms and retinopathy in a Chinese type 2 diabetes mellitus (T2DM) cohort.A total of 743 T2DM participants were involved in this study including 408 female and 335 male cases. Female cases were divided into two groups: diabetes without retinopathy (DNR group, n=171) and with retinopathy (DR group, n=237), the latter was further subclassified into nonproliferative DR (NPDR group, n=121) and proliferative DR (PDR group, n=116). Male cases were assigned to DNR group (n=153) and DR group (n=182) which was further grouped into NPDR group (n=86) and PDR group (n=96). Two single nucleotide polymorphisms (SNPs; rs2074192 and rs714205) in ACE2 gene were genotyped.In female cases, the frequency of genotypes TT in rs2074192 and CC in rs714205 were higher in DR and PDR group than in DNR group (P<0.05). The frequency of alleles T in SNP rs2074192 and C in SNP rs714205 was higher in DR group (P<0.05) and PDR group (P<0.05) than in DNR group. The frequency of allele T in SNP rs2074192 was higher in PDR group (P=0.04) than in NPDR group. The frequency of haplotype TC and CG was higher in DR and PDR groups, respectively (P<0.05). No positive results were found in male cases.Our results revealed that SNPs rs2074192 and rs714205 in ACE2 gene were associated with the susceptibility of DR and PDR.

Project description:ImportanceThe renin-angiotensin system has been implicated in mood disorders. Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are among the most commonly used medications, yet their effects on mental health outcomes, particularly suicide, are poorly understood. This study examined the association between suicide and exposure to ACEIs and ARBs. Because of differences in their mode of action, it was speculated that ARBs would be associated with a higher risk of suicide than ACEIs.ObjectiveTo examine the association between suicide and exposure to ARBs compared with ACEIs.Design, setting, and participantsThis population-based nested case-control study of individuals aged 66 years and older used administrative claims databases in Ontario, Canada, from January 1, 1995, to December 31, 2015. Data analysis was performed from January to April 2019. Cases were individuals who died by suicide within 100 days of receiving an ACEI or ARB. The date of death served as the index date. For each case, 4 controls were identified and matched by age (within 1 year), sex, and presence of hypertension and diabetes. All individuals received an ACEI or ARB within 100 days before the index date.ExposuresUse of an ACEI or ARB.Main outcomes and measuresConditional logistic regression was used to estimate odds ratios for the association between suicide and exposure to ARBs compared with ACEIs.ResultsNine hundred sixty-four cases were matched to 3856 controls. The median (interquartile range) age of cases and controls was 76 (70-82) years. Most cases (768 [79.7%]) and controls (3068 [79.6%]) were men. Among cases, 260 (26.0%) were exposed to ARBs, and 704 (18.4%) were exposed to ACEIs. Among controls, 741 (74.0%) were exposed to ARBs, and 3115 (81.6%) were exposed to ACEIs. Compared with ACEI exposure, ARB exposure was associated with higher risk of death by suicide (adjusted odds ratio, 1.63; 95% CI, 1.33-2.00). The findings were consistent in a sensitivity analysis excluding individuals with a history of self-harm (odds ratio, 1.60; 95% CI, 1.29-1.98).Conclusions and relevanceThe use of ARBs may be associated with an increased risk of suicide compared with ACEIs. Preferential use of ACEIs over ARBs should be considered whenever possible, particularly in patients with severe mental health illness.
