Metabolic syndrome in preeclampsia women in gorgan

Protective Effect of Akkermansia muciniphila on the Preeclampsia-Like Mouse Model

Preeclampsia (PE) is known as a metabolism-related complication of pregnancy related to gut dysbiosis including the decreased abundance of Akkermansia muciniphila (A. muciniphila). However, the modulatory role of A. muciniphila as a supplement for PE remains ambiguous. This study investigated the effect of A. muciniphila administration on PE-like mice and its underlying mechanisms. A total of twenty-four C57BL/6 mice were randomly assigned into three groups. PE-like symptoms were induced by continuous injection of L-NAME intraperitoneally from gestational day (GD) 11 to GD18 combined with oral administration of pasteurized A. muciniphila during GD14-18 or not. Mice were sacrificed at GD19 to collect for further evaluation. Decreased A. muciniphila was observed in a successfully established PE-like model than normotensive pregnant control (NP), inversely correlated to increased systolic blood pressure blood and 24-h proteinuria. After supplementing with A. muciniphila, mice showed significantly minimized blood pressure and protein expression in urine, increased number of pups and weight of both embryos and placentas. In addition, colonies of bacteria, inflammatory cytokines (TNF-α and IL-6), and metabolic products of lipids including TC, FC, and TG were alleviated by A. muciniphila in the placentas. Among proteins linked with bowel barrier functions, diminished 2-AG and growing ZO-1 and occludin were attributable to A. muciniphila. Also, enhanced Treg/Th17 ratios were found in the intestines of mice treated with A. muciniphila. A. muciniphila facilitated alleviating PE-like symptoms and was beneficial as a novel probiotic therapeutic agent for PE.

Adverse pregnancy outcomes and future risk of heart failure

PURPOSE OF REVIEW

Cardiovascular disease (CVD) is the leading cause of death in women. Women with history of adverse pregnancy outcomes (APOs) have approximately two-fold risk of future CVD, but until recently the association with future heart failure (HF) was unclear. Here, we summarize evidence for associations of APOs with HF, potential underlying mechanisms, and future directions for clinical translation.

RECENT FINDINGS

Women with history of hypertensive disorders of pregnancy (HDPs) have roughly two-fold risk of future HF compared with other parous women even after accounting for interval development of coronary artery disease. The HDPs portend heightened risk of HF with both reduced and preserved ejection fraction. Gestational diabetes mellitus (GDM) and other APOs such as preterm delivery, small-for-gestational-age delivery, and placental abruption may also confer additional risk for HF development. Possible underlying mechanisms linking APOs to HF include shared upstream risk factors and genetics, accelerated development of cardiometabolic risk factors postpartum, persistent endothelial and microvascular dysfunction, and impaired natriuretic peptide signaling.

SUMMARY

History of APOs, including HDPs and GDM, confer increased risk for development of HF years after delivery. Further research is needed to define strategies to optimize prepregnancy and postpartum cardiovascular health toward HF prevention.

Effects of Probiotic Supplementation during Pregnancy on the Future Maternal Risk of Metabolic Syndrome

Probiotics are live microorganisms that induce health benefits in the host. Taking probiotics is generally safe and well tolerated by pregnant women and their children. Consumption of probiotics can result in both prophylactic and therapeutic effects. In healthy adult humans, the gut microbiome is stable at the level of the dominant taxa: Bacteroidetes, Firmicutes and Actinobacteria, and has a higher presence of Verrucomicrobia. During pregnancy, an increase in the number of Proteobacteria and Actinobacteria phyla and a decrease in the beneficial species Roseburia intestinalis and Faecalibacterium prausnitzii are observed. Pregnancy is a "window" to the mother's future health. The aim of this paper is to review studies assessing the potentially beneficial effects of probiotics in preventing the development of diseases that appear during pregnancy, which are currently considered as risk factors for the development of metabolic syndrome, and consequently, reducing the risk of developing maternal metabolic syndrome in the future. The use of probiotics in gestational diabetes mellitus, preeclampsia and excessive gestational weight gain is reviewed. Probiotics are a relatively new intervention that can prevent the development of these disorders during pregnancy, and thus, would reduce the risk of metabolic syndrome resulting from these disorders in the mother's future.
