Association between Interleukin-10 gene polymorphisms and risk of early-onset preeclampsia.

ABSTRACT: We conducted a case-control study to investigate the role of IL-10 -1082A/G (rs1800896), -819T/C (rs1800871), and -592A/C (rs1800872) polymorphisms in the development of early-onset preeclampsia. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay was applied to assess the polymorphisms of IL-10 -1082A/G (rs1800896), -819T/C (rs1800871), and -592A/C (rs1800872). The genotype distributions of IL-10 -1082A/G (rs1800896), -819T/C (rs1800871), and -592A/C (rs1800872) confirmed with HWE in the controls, and the P value for HWE was 0.41, 0.38 and 0.26, respectively. The results of the multivariate logistic regression analysis revealed that the association of individuals expressing the CC genotype and AC+CC of IL-10 -592A/C (rs1800872) with a significantly increased risk of early-onset preeclampsia in co-dominant and dominant models, compared to the AA genotype; the OR (95% CI) for these individuals was determined to be 2.09 (1.12-3.90) and 1.66 (1.03-2.71), respectively. In the recessive model, we found that CC genotype of IL-10 -592A/C (rs1800872) was associated with the increased risk of early-onset preeclampsia when compared with AA+AC genotype (OR = 1.67; 95% CI = 1.01-2.92). In conclusion, our study has indicated that IL-10 -592A/C (rs1800872) polymorphism was associated with an increased risk of early-onset preeclampsia in a Chinese population.

Project description:BackgroundPreeclampsia is a serious pregnancy-specific syndrome with incompletely understood pathogenesis. Previous study has demonstrated that the decreased CXCR2 in preeclamptic placentas may contribute to the development of preeclampsia. The role of single nucleotide polymorphisms (SNPs) of CXCR2 gene in the pathogenesis of preeclampsia remains largely unexplored. Thus, we aimed to investigate the association between polymorphisms of CXCR2 gene and preeclampsia in Han Chinese women.MethodsTotally 481 pregnant women, including 243 controls and 238 patients with preeclampsia were recruited. The rs1126579 and rs2230054 polymorphisms in CXCR2 gene were tested using polymerase chain reaction-restriction fragment length polymorphism method.ResultsSignificantly increased risk of preeclampsia was observed in the rs1126579 CC or TC/CC genotypes when compared with TT genotype (CC vs. TT: odss ratio [OR] = 2.11, 95% confidence interval [CI] = 1.18-3.76, p = 0.039; TC/CC vs. TT: OR = 1.89, 95% CI = 1.29-2.78, p = 0.001). Markedly higher risk of preeclampsia was found to be associated with rs1126579 TC genotype (TC vs. TT/CC: OR = 1.48, 95% CI = 1.04-2.12, p = 0.031). After stratification analysis, the different distribution of TC/CC genotypes was particularly significant in the severe preeclampsia group (OR = 2.15, 95% CI = 1.42-3.24, p < 0.01), the early-onset severe preeclampsia group (OR = 1.97, 95% CI = 1.14-3.42, p = 0.013), and the late-onset severe preeclampsia group (OR = 2.29, 95% CI = 1.39-3.78, p < 0.01). Besides, TC genotype carriers had a 1.55 fold increased risk of severe preeclampsia (95% CI = 1.06-2.27, p = 0.022) and a 1.80 fold increased risk of late onset severe preeclampsia (95% CI = 1.14-2.83, p = 0.01) than those of TT/CC genotype carriers.ConclusionsOur study suggests a genetic association between rs1126579 polymorphism in CXCR2 gene and increased risk of preeclampsia. These data provide a new clue for future investigation.

Project description:BackgroundInterleukin-10 (IL-10) is an important immunomodulatory cytokine. Several studies focused the association between IL-10 promoter gene polymorphisms and graft rejection risk in kidney transplantation recipients. However, the results of these studies remain inconclusive. The aim of this study was to conduct a meta-analysis to further assess the associations.MethodsThe PubMed, Embase, and Ovid Medline databases were searched. Two independent authors extracted data, and the effects were estimated from an odds ratio (OR) with 95% confidence intervals (CIs). Subgroup and sensitivity analyses identified sources of heterogeneity.ResultsA total of 16 studies including 595 rejection patients and 1239 stable graft patients were included in order to study the IL-10 -1082 (rs1800896 G/A), -819 (rs1800871 C/T), -592 (rs1800872 C/A) and IL-10 (-1082,-819,-592) polymorphisms. The -1082 G/A polymorphism was not associated with an increased graft rejection risk (OR = 1.03; 95%CI, 0.85-1.25, P = 0.74 for GA+AA vs. GG model). Moreover, all of the -819 C/T (OR = 1.06, 95%CI, 0.79-1.42, P = 0.70 for TA+TT vs. CC model), -592 C/A (OR = 1.10, 95% CI, 0.85-1.42, P = 0.47 for AC+AA vs. CC model) and IL-10 (-1082,-819,-592) polymorphisms (OR = 1.00, 95%CI, 0.79-1.27, P = 0.98 for I+L vs. H model) did not increase the graft rejection risk. In addition, we also performed subgroup analysis by ethnic group (mainly in Europeans or Asians) and rejection type (acute or chronic). There was also lack of evidence of a significant association between the IL-10 gene polymorphism and graft rejection risk. The present meta-analysis indicated that the IL-10 gene polymorphism was not associated with graft rejection risk in kidney transplantation recipients.ConclusionThis meta-analysis found evidence that the IL-10 polymorphism does not increase the risk of graft rejection in kidney transplantation recipients. Further chronic rejection and other ethnic population studies are needed to confirm our results.
