AI Article Synopsis

  • The study aimed to explore the link between the PLA2G7 gene polymorphisms (G994T and R92H) and the risk of developing preeclampsia (PE) in Chinese women, using a case-control design involving 273 PE patients and 530 healthy pregnant women.
  • Significant findings showed that the G994T polymorphism was more common in PE patients, with the GT + TT genotype associated with a higher risk for PE even after adjusting for factors like age and BMI (odds ratio = 4.926).
  • The study concluded that the G994T polymorphism increases the risk of preeclampsia, while the R92H polymorphism had no significant association.

Article Abstract

Objective: To investigate the relationship between platelet-activating factor acetylhydrolase (PAF-AH) gene (PLA2G7) G994T (V279F, rs76863441) and R92H (rs1805017) polymorphisms and risk of preeclampsia (PE) in Chinese women.

Study Design: This is a case-control study of 273 patients with PE and 530 healthy pregnant women.

Main Outcome Measures: PLA2G7 genotypes were determined by polymerase chain reaction amplification and restriction analysis. Plasma PAF-AH, apolipoprotein (apo) B-containing lipoprotein-associated PAF-AH (apoB-PAF-AH), total high-density lipoprotein (HDL)-associated PAF-AH (H-PAF-AH), apoE-containing HDL-associated PAF-AH (apoE-H-PAF-AH) activities, and clinical, metabolic, and oxidative stress parameters were also analyzed.

Results: The frequencies of the GT + TT genotype (14.7 versus 9.2%, P = 0.019) and T allele (7.5% versus 4.6%) of PLA2G7 G994T polymorphism were significantly higher in patients with PE than in the control subjects. The GT + TT genotypes remained a significant predictor for PE in a regression model including age, body mass index (BMI), plasma PAF-AH, H-PAF-AH, apoE-H-PAF-AH and apoB-PAF-AH activities as covariates (odds ratio (OR) = 4.926, 95% confidence interval (CI): 1.707-14.219, P = 0.003). The ratio of apoB-PAF-AH to H-PAF-AH activities was significantly higher, while serum triglyceride levels were lower in patients with the GT genotype compared with patients with the GG genotype (P < 0.05). No significant differences were observed in the frequencies of the R92H genotype and allele between the PE and control groups.

Conclusions: The PLA2G7 G994T, but not R92H, genetic polymorphism is associated with the risk of PE in Chinese women.

Background: IgG antibodies (Abs) to platelet factor 4 complexed to heparin (PF4/H) commonly occur after heparin exposure but cause life-threatening complications of heparin-induced thrombocytopenia (HIT) in only a few patients. Presently, only platelet activation assays reliably distinguish anti-PF4/H Abs that cause disease (HIT Abs) from those likely to be asymptomatic (AAbs).

Objectives: Recent studies indicate that complement activation is an important serologic property of HIT Abs and is essential for FcγRIIA-mediated cellular activation.

Angiogenesis, a key point in the association of gut microbiota and its metabolites with disease.

The gut microbiota is a complex and dynamic ecosystem that plays a crucial role in human health and disease, including obesity, diabetes, cardiovascular diseases, neurodegenerative diseases, inflammatory bowel disease, and cancer. Chronic inflammation is a common feature of these diseases and is closely related to angiogenesis (the process of forming new blood vessels), which is often dysregulated in pathological conditions. Inflammation potentially acts as a central mediator.

The threats to chemical warfare-associated agents (CWA), including nitrogen mustard, are increasing, and no direct antidote is currently available to mitigate the deleterious cutaneous and systemic responses to prevent mortality. Though most of these agents act as alkylating agents, a significant knowledge gap exists in the molecular mechanisms of how these vesicants cause toxic effects. Studies, including ours, have shown that exposure to reactive oxygen species (ROS)-generating stimuli, including alkylating chemotherapeutic agents, and thermal burn injuries with ethanol produce the potent family of lipid mediators, Platelet-activating factor (PAF) agonists that induce local inflammation, and multi-system organ dysfunction (MOD).

Platelet-Neutrophil aggregate formation induces NLRP3 inflammasome activation in VITT.

Background: Although rare, vaccine-induced thrombotic thrombocytopenia (VITT) following adenoviral vector COVID-19 vaccination is a concerning and often severe adverse effect of vaccination. The generation of high anti-platelet factor 4 (PF4) antibody titers, promotes the formation of immune complexes capable of activating platelets and neutrophils through FcγRIIa.

Objective: Given that Platelet-leukocyte aggregate (PLA) formation and inflammasome activation are common features of thromboinflammatory diseases, we aimed to evaluate if these are also features of VITT.

Excessive alcohol consumption is detrimental to human health, and it is implicated in the development of heart disease, stroke, and cancer. However, the last few decades have given rise to epidemiological evidence suggesting that low-to-moderate consumption of red wine and beer may reduce the risk of cardiovascular diseases. Studies have shown that moderate consumption of wine and beer protects against ischemic stroke, increases HDL plasma concentrations, and reduces platelet aggregation and insulin resistance.
