Association between Genetic Polymorphisms in DEFB1 and Susceptibility to Digestive Diseases.

ABSTRACT: Aberrant expression of defensins is implicated in the pathogenesis of digestive diseases. However, the contribution of specific defensins and the influence of their genetic polymorphisms on the progression of digestive diseases remain controversial. In the present meta-analysis, we investigated the association between DEFB1 SNPs and the susceptibility to digestive diseases.Case-control studies that reported the correlation between DEFB1 SNPs and the susceptibility to digestive diseases were identified through electronic databases searches, and high-quality studies that satisfied our inclusion criteria were selected for this meta-analysis. Statistical analyses were performed utilizing STATA software version 12.0.The present meta-analysis revealed that patients with digestive diseases exhibited higher frequencies of the DEFB1 genetic variants rs11362G>A, rs1800972C>G, and rs1799946G>A compared to healthy controls under the allele model. Subgroup analysis based on country showed that the rs1800972C>G variant under allele model and rs1799946G>A are associated with the susceptibility to digestive diseases in Hungarian and Italian populations, respectively. Subgroup analysis based on disease type showed that: (1) rs11362G>A variant was strongly associated with severe acute pancreatitis (SAP) and chronic gastritis, (2) frequency of rs1800972C>G variant was higher in SAP subgroup, and (3) frequency of rs1799946G>A variant was positively associated with the susceptibility to Crohn's disease (CD) under the allele model and with SAP.Our meta-analysis provides evidence that DEFB1 genetic polymorphisms rs11362G>A, rs1800972C>G and rs1799946G>A are important contributing factors to the development of digestive diseases.

Project description:BackgroundNew hypoglycemic agents include sodium-glucose cotransporter-2 inhibitors (SGLT2is), glucagon-like peptide 1 receptor agonists (GLP1RAs), and dipeptidyl peptidase-4 inhibitors (DPP4is). The association between each class of these new hypoglycemic drugs and the risks of various digestive system diseases is unknown. We aimed to explore this relationship by performing a meta-analysis.MethodsWe included large randomized trials of SGLT2is, GLP1RAs, and DPP4is. Outcomes of interest were 91 kinds of digestive diseases including 75 kinds of gastrointestinal disorders and 16 kinds of hepatobiliary disorders. Meta-analysis was done to generate pooled risk ratio (RR) and 95% confidence interval (CI). Subgroup analysis was conducted according to 3 different drug classes.ResultsWe included 21 large trials in this meta-analysis. Compared with placebo, GLP1RAs were associated with the higher risks of gastric ulcer hemorrhage (RR 2.68, 95% CI 1.07-6.68; Pdrug = .035; I2 = 0), pancreatitis (RR 1.48, 95% CI 1.02-2.15; Pdrug = .041; I2 = 0), cholangitis acute (RR 5.96, 95% CI 1.04-34.08; Pdrug = .045; I2 = 0), and cholecystitis acute (RR 1.52, 95% CI 1.08-2.15; Pdrug = .017; I2 = 1.5%), but were not significantly associated with the occurrences of the other 87 kinds of digestive diseases (Pdrug ranged from .064 to .999). SGLT2is versus placebo were not significantly associated with the occurrences of 91 kinds of digestive diseases (Pdrug ranged from .077 to .995). DPP4is versus placebo were not significantly associated with the occurrences of 91 kinds of digestive diseases (Pdrug ranged from .085 to .999).ConclusionsNeither SGLT2is nor DPP4is are associated with the occurrences of various kinds of digestive diseases, whereas GLP1RAs are associated with the higher risks of 4 kinds of digestive diseases, namely, gastric ulcer hemorrhage, pancreatitis, cholangitis acute, and cholecystitis acute. These findings seem to suggest that GLP1RAs are not applicable for patients at high risk of 4 specific digestive diseases, whereas SGLT2is and DPP4is are safe for patients susceptible to digestive diseases. However, our findings require to be further verified by future studies with sufficient statistical power.
