Systemic lupus erythematosus (SLE) mostly affects young women of reproductive age group. SLE patients may conceive as any normal woman but complication may occur in these patients if the disease is active. Pregnancy in SLE may lead to 1. Aggravation of SLE (Lupus flare) 2. Pre-term delivery, intrauterine growth retardation and foetal loss (in presence of antiphospholipid antibodies) 3. Neonatal lupus especially in presence of Anti-Ro / La antibody. For a successful pregnancy, both from maternal and foetal aspects, disease should be quiescent for at least six months before the conception...

Maternal prenatal anxiety is associated with infants' temperamental negative affectivity (NA), but it is unclear to what extent children vary in their susceptibility to prenatal influences. We tested a hypothesis that infants' respiratory sinus arrhythmia (RSA), an index of parasympathetic vagal tone and a potential marker of differential susceptibility to environmental influences, moderates the effects of maternal prenatal anxiety on the development of infant NA. Prenatal anxiety was assessed during the last trimester of pregnancy in a low-risk community sample...

Inflammation plays a key role in human term and preterm labor (PTL). Intrauterine LPS has been widely used to model inflammation induced complications of pregnancy including PTL. It has been shown to induce an intense myometrial inflammatory cell infiltration, but the role of LPS-induced inflammatory cell activation in labor onset and fetal demise is unclear. We investigated this using a mouse model of PTL, where an intrauterine injection of 10 µg of LPS (serotype 0111:B4) was given at E16 of CD1 mouse pregnancy...

Intrauterine growth restriction (IUGR) is a common pregnancy complication and is a leading cause of fetal morbidity and mortality. Placental hypoxia contributes to adverse fetal consequences, including IUGR. Exposing pregnant rats to hypoxia can lead to IUGR; however, assessment of maternal vascular function in a rat model of hypoxia, and the mechanisms that may contribute to adverse pregnancy outcomes, has not been extensively studied. We hypothesized that exposing pregnant rats to hypoxia will affect maternal systemic vascular function and increase the uterine artery resistance index (RI), which will be associated with IUGR...

Preeclampsia and intrauterine growth restriction are two separate disease entities that, according to numerous reports, share the same pathogenesis. In both, angiogenesis disorders and generalized inflammation are the dominant symptoms. In this study, we hypothesized that both diseases demonstrate the same profile in early preeclampsia, late preeclampsia, and intrauterine growth restriction patients, with the only difference being the degree of exacerbation of lesions. One hundred sixty-seven patients were enrolled in the study and divided into four groups: early preeclampsia, late preeclampsia, and intrauterine growth restriction groups, and one control group...

INTRODUCTION: Twin-twin transfusion syndrome (TTTS) is the major cause for fetal demise in monochorionic diamniotic pregnancies. Estimated combined cardiac output (CCO) has not been studied in this setting. The primary aims of this study were to compare CCO in twin donor and recipient fetuses and assess differences in CCO before and after laser coagulation therapy. A secondary aim was to evaluate the relationship of CCO with perinatal mortality, defined as intrauterine or neonatal mortality (≤30 days of age) in fetuses that underwent laser coagulation therapy...

OBJECTIVE: To determine whether adverse outcomes were more common in late preterm pregnancies complicated by preeclampsia and growth restriction compared to those affected by preeclampsia alone. METHODS: This was a retrospective cohort study of 8,927 singleton pregnancies with preeclampsia. Pregnancies with small for gestational age (SGA) neonates (birthweight <10(th) percentile) were compared to those appropriate for gestational age (AGA) neonates. Maternal outcomes included cesarean delivery (CD) rate, CD for fetal heart rate (FHR) abnormalities, abruption, postpartum hemorrhage (PPH), maternal transfusion, acute renal failure, and peripartum cardiomyopathy...

PURPOSE OF REVIEW: Selective intrauterine growth restriction (sIUGR) in twin pregnancies presents a complex management problem for the fetal medicine specialist. This review summarizes what is currently known about sIUGR pathophysiology, particularly in monochorionic pregnancies and looks at the results of early trials of fetal intervention in high-risk sIUGR pregnancies. RECENT FINDINGS: sIUGR in monochorionic pregnancies is due to unequal placental sharing, but the clinical outcome is determined by the characteristics of the placental vascular anastomoses...

The mechanism underlying the increased susceptibility of type 2 diabetes in offspring of maternal malnutrition is poorly determined. Here we tested the hypothesis that functional microRNAs (miRNAs) mediated the maternal low protein (LP) isocaloric diet induced pancreatic β-cell impairment. We performed miRNA profiling in the islets from offspring of LP and control diet mothers to explore the potential functional miRNAs responsible for β-cell dysfunction. We found that LP offspring exhibited impaired glucose tolerance due to decreased β-cell mass and insulin secretion...

OBJECTIVE: Superimposed pre-eclampsia (SPE) is resolved only with the termination of the pregnancy. Therefore, the risk prediction and prevention is very important. We aimed to evaluate the characteristics of patients who develop SPE and their controllable risk factors during mid-trimester. DESIGN AND METHOD: A total of 283 pregnant women with chronic hypertension were included for the study. Blood pressure (BP) and body weight were recorded at 10, 20, 24, 28, and 32 weeks of gestation and pregnancy outcomes were evaluated...

OBJECTIVE: Placental activation of the renin-angiotensin system (RAS) plays an important role in pathogenesis of preeclampsia. RAS induces reactive oxygen species (ROS) production by activating NADPH oxidases. Keap1-Nrf2 system is a critical regulator for cellular anti-oxidative stress response through controlling transcription of antioxidant genes. This study has explored the relationship between RAS-induced ROS signaling and Keap1-Nrf2 system in preeclampsia. DESIGN AND METHOD: To examine the contribution of Keap1-Nrf2 system to preeclampsia pathology, we generated transgenic mouse models of preeclampsia/pregnancy-associated hypertension (PAH mice), in which RAS is activated selectively in late pregnancy, under deficient, normal or active Nrf2 conditions...

Pre-eclampsia is a pregnancy-specific hypertensive disorder that affects 2-8 % of pregnancies. This disorder can lead to seizure, multi-organ failure and maternal death. The best approach to prevent pre-eclampsia-associated adverse outcomes is to be able to prevent pre-eclampsia as early as possible. Unfortunately, current diagnostic methods are ineffective at predicting the risk of pre-eclampsia during early pregnancy. In humans, low levels of a group of placenta-derived Pregnancy Specific Glycoproteins (PSGs) have been associated with intrauterine growth retardation and pre-eclampsia and there is a significant enrichment of cases with deletions in the PSG gene locus in pre-eclampsia patients...

OBJECTIVE: To study the postnatal changes in lymphocyte subsets in early preterm infants and the effect of perinatal factors on lymphocyte subsets. METHODS: A total of 61 early preterm infants were enrolled. Flow cytometry was used to measure the absolute counts of lymphocytes and lymphocyte subsets at 1, 7, 14, and 28 days after birth, as well as at 6 months after birth for 17 of these early preterm infants. The effects of perinatal factors, such as antepartum use of hormone, intrauterine infection, gestational age at birth, and Ureaplasma urealyticum (UU) colonization, on lymphocyte subsets were analyzed...

BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) is a specific pregnancy-related disorder without standard medical therapies. Ursodeoxycholic acid (UDCA) is the most used medicine, but the efficacy and safety of UDCA remain uncertain. Several meta-analyses had been made to assess the effects of UDCA in ICP. However, the samples were not large enough to convince obstetricians to use UDCA. We conducted a meta-analysis to evaluate the effects and safety of UDCA in patients with ICP, which included only randomized controlled trials (RCTs)...

Most non-immune individuals exposed to the highly contagious measles virus will develop measles. Complications, such as encephalitis and bacterial infections due to measles virus-induced immunomodulation, account for an acute mortality rate of approximately 0.1% (1). It has been calculated that measles-related immunomodulation may last for several years and may contribute to child mortality on a larger scale than acute measles-related mortality (2). Since humans provide the only host for the virus, and an efficient vaccine is available, it is possible to eliminate measles...
