OBJECTIVES: Hypertensive disorders of pregnancy (HDP) represent the most common cause of maternal-fetal morbidity and mortality. Yet, the prevalence and cost of postpartum (42-day) readmission (PPR) among HDP-complicated pregnancies in the United States remains unknown. This study provides national prevalence and cost estimates of HDP, and examine factors associated with potentially preventable PPR following HDP-complicated pregnancies. METHOD: The 2013 and 2014 Nationwide Readmissions Databases were used to investigate HDP and PPR among delivery hospitalizations to women aged 15-49 years...

Lewis blood group antibodies, which are mostly naturally occurring and considered clinically insignificant, have rarely been documented as a cause of acute hemolytic transfusion reactions (AHTRs). This report presents two cases of AHTRs caused by anti-Lea occurring in postpartum black females (one group B, one group AB) whose pregnancies were complicated by preeclampsia. Neither anti-Lea was detected by automated solid-phase red cell adherence technology in pre-transfusion testing. Therefore, red blood cell units, compatible by electronic crossmatch, were issued and transfused...

Microvascular dysfunction originating during a preeclamptic pregnancy persists postpartum and likely contributes to increased CVD risk in these women. One putative mechanism contributing to this dysfunction is increased vasoconstrictor sensitivity to endothelin-1 (ET-1), mediated by alterations in ET-1 receptor type-B (ETBR). We evaluated ET-1 sensitivity, ETAR and ETBR contributions to ET-1-mediated constriction, and the mechanistic role of  ETBR in endothelium-dependent dilation in vivo in the microvasculature of postpartum women who had preeclampsia (PrEC, n=12) and control women who had a healthy pregnancy (HC, n=12)...

OBJECTIVE: As a frequent hypertensive disorder in pregnancy, preeclampsia causes 15% of all preterm deliveries. This study aims to understand its mechanism via analyzing gene expression and methylation data. METHODS: Human gene expression microarray data (GSE73374) and corresponding DNA methylation microarray data (GSE73375) of preeclamptic placental tissues (n = 19) and normotensive placental tissues (n = 17) were obtained from the Gene Expression Omnibus. Differentially expressed genes (DEGs), differentially methylated regions (DMRs) and CpG islands (DMIs) were identified and compared...

Aspirin is currently the most widely prescribed treatment in the prevention of cardiovascular complications. The indications for the use of aspirin during pregnancy are, however, the subject of much controversy. Since the first evidence of the obstetric efficacy of aspirin in 1985, numerous studies have tried to determine the effect of low-dose aspirin on the incidence of preeclampsia, with very controversial results. Large meta-analyses including individual patient data have demonstrated that aspirin is effective in preventing preeclampsia in high-risk patients, mainly those with a history of preeclampsia...

REVIEW
Amel A F El-Sayed
This review is divided into three parts. The first part briefly describes the pathogenesis of preeclampsia. This is followed by reviewing previously reported management strategies of the disease based on its pathophysiological derangements. Finally, the author defines the safe and acceptable methods/medications that may be used to 'prevent' preeclampsia (in high risk patients) and those that may be used to 'treat' preeclampsia (meant to prolong the pregnancy in patients with established preeclampsia). The review concludes that multi-center trials are required to include multiple drugs in the same management protocol...

A clinical review of risk factors, diagnostic criteria, and patient care. ABSTRACT: Preeclampsia, one of four hypertensive disorders of pregnancy, has traditionally been characterized as new-onset hypertension and proteinuria developing after 20 weeks' gestation. It is, however, now understood to be a complex, progressive, multisystem disorder with a highly variable presentation and a number of potentially life-threatening complications. The American College of Obstetricians and Gynecologists Task Force on Hypertension in Pregnancy has refined preeclampsia diagnostic criteria accordingly, and as the disorder's pathogenesis has been more clearly defined, new targets for screening, diagnosis, prevention, and treatment have emerged...

It is not clear whether infection with cytomegalovirus (CMV) is associated with hypertensive disorders in pregnant women. Through a case-control study design, 146 women suffering from hypertensive disorders in pregnancy (cases) and 146 age-matched normotensive pregnant women (controls) were examined for the presence of anti-CMV IgG and IgM antibodies with enzyme-linked immunoassays. IgM seropositive samples were further assayed by enzyme-linked fluorescent assay (ELFA). Anti-CMV IgG antibodies were found in 138 (94...

Hypertensive disorders affect about one third of all people aged 20 and above, and are treated with anti-hypertensive drugs. Preeclampsia (PE) is one form of such disorders that only develops during pregnancy. It affects ten million pregnant women globally and additionally causes fetal loss and major newborn disabilities. The syndrome's origin is multifactorial, and anti-hypertensive drugs are ineffective in treating it. Biomarkers are helpful for predict its development. Generic drugs, such as low dose aspirin, were proven effective in preventing preterm PE...

Pre-eclampsia is a disease of pregnancy affecting 5%-8% of all pregnancies and a leading cause of maternal and fetal mortality. Despite improvements in the diagnosis, there is no effective method for prevention and treatment. While studies in women are of critical importance, investigation of pathological mechanisms in pregnant women is necessarily limited, and the ability to establish cause and effect relationships, difficult. Mouse models have been instrumental in defining pathogenic mechanisms in preeclampsia and in the identification of pravastatin as a potential treatment to prevent pregnancy complications associated with placental dysfunction...

Background: We sought to determine if immune disorders early in life were associated with the later risk of Guillain-Barré syndrome, a neurological disorder thought to be infection-related. Methods: We conducted a longitudinal cohort study with 16 108 819 person-years of follow-up for a population of 1 108 541 parous women in Quebec, Canada (1989-2014). The outcome was Guillain-Barré syndrome. We identified women with potential risk factors for future Guillain-Barré syndrome, including immune-mediated and rheumatological diseases, cancer, transfusion, surgical procedures and pregnancy-specific disorders...

Preeclampsia (PE) is one of the most common pregnancy-specific pathologic complications, and is characterised by onset of hypertension and proteinuria. Placental trophoblast cell apoptosis is generally accepted as a major cause of PE. However, the details of the mechanism underlying the condition remain unclear. Here, we aimed to investigate a possible association between microRNA (miR)-34a and human trophoblast cell apoptosis during PE. We evaluated miR-34a expression in placentas from patients with PE compared with those from healthy pregnant individuals...

BACKGROUND: Preterm birth (PTB) is a multifactorial syndrome occurring before the 37th week of full-term pregnancy [1]. Babies delivered preterm experience short-term and long-term complications affecting multiple organ systems, and serious maternal complications include hemorrhage and infection. Each year, an estimated 15 million babies are born preterm, and complications from prematurity are the leading cause of death among children up to 5 years of age [2]. With another increase in PTB rates over the last several years, the United States continues to have the highest incidence of any industrialized country [3]...
