AB  - Objectives: Establishment of association between: (a) Val158Met COMT (G1947A) polymorphism and preeclampsia; (b) cytokines gene expression and COMT genotypes. Methods: 50 preeclampsia and 50 healthy pregnant women were enrolled. COMT genotyping was done by PCR/RFLP. TNF-α, IL-1β, and IL-6 mRNA levels were determined by Real-time PCR. Results: Variant (AA) homozygotes carried 3.7-fold increased preeclampsia odds, especially for severe (OR = 9.0, 95%CI (2.09-38.799)) and early forms (OR = 6.6, 95%CI (1.62-26.87)). AA homozygotes with PE had higher TNF-α levels compared to controls (P = 0.012). Conclusions: Val158Met COMT polymorphism increases preeclampsia risk. TNF-α expression and Val158Met COMT polymorphism have concomitant roles in PE pathogenesis.

AB  - Insufficient response to oxidative stress in placenta is proposed as a contributing factor for preeclampsia (PE) development. Glutathione S-transferases (GST) have significant role in detoxification processes. Conflicting results were published by several research groups regarding GST T1 and GST M1 deletion polymorphism as risk factors for PE. The aim of the present meta-analysis was to get a better understanding of the impact of these polymorphisms in preeclampsia development. To identify relevant case-control studies, the author team searched Clarivate Analytics Web of Science, Scopus, PubMed, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, major subject journals, and gray literature. Pooled odds ratios and 95% confidence intervals for GST M1 and GST T1 deletion polymorphism and preeclampsia were derived from random effects models. This meta-analysis included 10 eligible studies. The pooled analyses showed no association between GST M1/GST T1 deletion polymorphisms and susceptibility to PE. Even though high heterogeneity was founded among results for GST M1 and double null genotypes, Egger's and Begg's tests (0.17 and 0.18, respectively) revealed no statistical evidence of publication bias among included studies. The present updated systematic review and meta-analysis found no association between GST M1 and GST T1 deletion polymorphism and PE risk.

AB  - Problem Preeclampsia has a multifactorial origin with genetic, immunological, and environmental factors described as main contributors to its onset. This study aimed to investigate glutathione-S-transferase M1 (GSTM1) and glutathione-S-transferase T1 (GSTT1) gene polymorphisms, the expression of pro-inflammatory cytokines (TNF-alpha, IL-1 beta, IL-6), and the potential relationship between GST polymorphisms and cytokine expression levels in preeclampsia and uncomplicated pregnancy. Method of Study This prospective case-control study included 50 women with preeclampsia and 50 healthy pregnant women. DNA and RNA were extracted from women leukocytes. Deletion polymorphisms were analyzed by PCR, while cytokine mRNA expression was analyzed by real-time PCR. Results GSTM1 null genotype with present GSTT1 increased the risk for preeclampsia development. Deletion of GSTT1 without deletion of GSTM1 increased the risk for early preeclampsia. Relative mRNA expression of TNF-alpha was significantly higher in preeclampsia compared to healthy pregnant women (P = 0.006). Expression of IL-1 beta was significantly higher in severe and late preeclampsia compared to the control group (P = 0.005, P = 0.007, respectively). A significant positive correlation between TNF-alpha and IL-1 beta was observed (Spearman's rho = 0.312, P = 0.028) and between IL-1 beta and IL-6, in preeclampsia group (Spearman's rho = 0.296, P = 0.037). IL-1 beta was significantly increased in patients with GSTT1 null genotype (P = 0.015) while IL-6 was increased in patients with GSTM1 null genotype (P = 0.015). Conclusions GSTM1 null genotype represents a risk factor for preeclampsia development, while GSTT1 null genotype favors early preeclampsia. Preeclampsia is also associated with increased expression of pro-inflammatory cytokines, predominantly TNF-alpha and IL-1 beta.
