High plasma concentration of uric acid are frequently associated with inflammation and endothelial dysfunction and may contribute to PE pathogenesis. This study aimed to evaluate the vitamin D (VD) immunomodulatory effect on the NLRP1/NLRP3 inflammasomes in placental explants from preeclamptic (PE) and normotensive (NT) pregnant women. Study design Placental explants from 10 late-onset PE (LOPE), 10 early-onset PE (EOPE), and 10 NT pregnant women were cultured with or without monosodium urate (MSU) and VD. Main outcome measures Gene and protein expression of NLRP1, NLRP3, HMGB1, caspase-1, interleukin-1 beta (IL-1β), and IL-18 were determined by quantitative PCR and Western blotting/ELISA. Statistical significance was accepted at p < 0.05. Results Basal gene and protein expression of NLRP1/NLRP3 and IL-1β, IL-18 and HMGB1 were significantly higher in explants from EOPE compared to LOPE and NT pregnant women. In addition, culture with MSU increased these inflammatory markers, and concomitant treatment with MSU+VD decreased this effect. Conclusions The results demonstrated that NLRP1 and NLRP3 inflammasomes are upregulated in the placental tissue of EOPE women, associated with high production of inflammatory cytokines. The in vitro treatment with VD downregulated placental inflammasomes induced by MSU, suggesting its immunomodulatory role in the systemic inflammation of PE.","PeriodicalId":13054,"journal":{"name":"Hypertension in Pregnancy","volume":"41 1","pages":"139 - 148"},"PeriodicalIF":1.5,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45883813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the acute hemodynamic effects of PlGF in vivo are not known. The aim of this study was to report acute cardiovascular changes induced by recombinant human PlGF administered intravenously in male Guinea Pigs with implanted telemeters. PlGF decreased mean arterial blood pressure by 10–20% within minutes. The magnitude of reduction was similar at three dose levels; however, the duration of relative hypotension was dose-dependent. Blood pressure reduction resulted in a compensatory increase in heart rate, or reflex tachycardia. To rule out any direct effect on the heart, PlGF was tested in the ex vivo Langendorff heart preparation, and no cardiac changes were found. Together these results suggest that the PlGF-related changes in blood pressure are largely mediated by its actions in the vasculature.","PeriodicalId":13054,"journal":{"name":"Hypertension in Pregnancy","volume":"41 1","pages":"99 - 106"},"PeriodicalIF":1.5,"publicationDate":"2022-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46492299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods A total of 20 PPCM patients who exhibited LV recovery (ejection fraction ≥50%) in the follow-up period and 20 age-matched, healthy women were included in the study. Standard 2D echocardiographic examinations were performed. Global longitudinal strain and global circumferential strain were analyzed. Results Age, weight, body surface area, smoking, heart rate, and systolic and diastolic blood pressure were similar in both groups. Echocardiographic examination showed no significant difference between both groups. Only the global longitudinal strain (18.1 ± 2.7 vs 20.16 ± 1.7, p = 0.02) and global circumferential strain (22.1 ± 2.9 vs 24.4 ± 1.19, p = 0.01) were significantly lower in PPCM patients. The lowest values for longitudinal strain belonged to the basal and mid regions of anterior, anteroseptal and lateral walls in the PPCM patients. Conclusion Subclinical myocardial damage may persist in PPCM patients with full LV systolic recovery. 3D Speckle Tracking strain analysis is a useful method for detecting subtle myocardial dysfunction.","PeriodicalId":13054,"journal":{"name":"Hypertension in Pregnancy","volume":"41 1","pages":"89 - 96"},"PeriodicalIF":1.5,"publicationDate":"2022-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43140319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
