Guillain-Barré syndrome (GBS) is a rare autoimmune disorder that affects the peripheral nervous system. The purpose of our study was to evaluate maternal and fetal/neonatal outcomes among pregnancies complicated by GBS.We performed a retrospective cohort study using the Healthcare Cost and Utilization Project – National Inpatient Sample from the United States. ICD-9 codes were used to identify all pregnant women who delivered between 1999 and 2015 and had a diagnosis of GBS. The remaining women without GBS who delivered during that time period constituted the comparison group. The associations between maternal GBS and obstetrical and fetal/neonatal outcomes were evaluated using multivariate logistic regression, while adjusting for the confounding effects of maternal characteristics.Of 13,792,544 births included in our study, 291 were to women with GBS, for an overall incidence of 2.1/100,000 births. A steady increase in maternal GBS was observed over the study period (from 1.26 to 3.8/100,000 births, p=0.02). Further, women with GBS were more likely to have pregnancies complicated by preeclampsia, OR 1.69 (95 % CI 1.06–2.69), sepsis, 9.30 (2.33–37.17), postpartum hemorrhage, 1.83 (1.07–3.14), and to require a transfusion, 4.39 (2.39–8.05). They were also at greater risk of caesarean delivery, 2.07 (1.58–2.72) and increased length of hospital stay, 4.48 (3.00–6.69). Newborns of women with GBS were more likely to be growth restricted, 2.50 (1.48–4.23).GBS in pregnancy is associated with maternal and newborn adverse outcomes. These patients would benefit from close follow-up throughout their pregnancy and in the postpartum period. [ABSTRACT FROM AUTHOR]

Acute pancreatitis is a rare condition that can be associated with significant complications. The objective of this study is to evaluate the maternal and newborn outcomes associated with acute pancreatitis in pregnancy. A retrospective cohort study using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from the United States was performed. All pregnant patients with acute pancreatitis were identified using International Classification of Disease-9 coding from 1999 to 2015. The effect of acute pancreatitis on maternal and neonatal outcomes in pregnancy was evaluated using multivariate logistic regression, while adjusting for baseline maternal characteristics. From 1999 to 2015, there were a total of 13,815,919 women who gave birth. There were a total of 14,258 admissions of women diagnosed with acute pancreatitis, including 1,756 who delivered during their admission and 12,502 women who were admitted in the antepartum period and did not deliver during the same admission. Acute pancreatitis was associated with increased risk of prematurity, OR 3.78 (95% CI 3.38–4.22), preeclampsia, 3.81(3.33–4.36), postpartum hemorrhage, 1.90(1.55–2.33), maternal death, 9.15(6.05–13.85), and fetal demise, 2.60(1.86–3.62) among women diagnosed with acute pancreatitis. Among women with acute pancreatitis, delivery was associated with increased risk of requiring transfusions, 6.06(4.87–7.54), developing venous thromboembolisms, 2.77(1.83–4.18), acute respiratory failure, 3.66(2.73–4.91), and disseminated intravascular coagulation, 8.12(4.12–16.03). Acute pancreatitis in pregnancy is associated with severe complications, such as maternal and fetal death. Understanding the risk factors that may lead to these complications can help prevent or minimize them through close fetal and maternal monitoring. [ABSTRACT FROM AUTHOR]

Background: Behcet's disease (BD) is a rare, multi-systemic inflammatory disorder for which only limited and contradictory data exists in the context of pregnancy. Our objective was to estimate the prevalence of BD in pregnancy and to evaluate maternal and fetal outcomes associated with pregnant women living with BD. Methods: Using the 1999--2013 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from the United States, we performed a population-based retrospective cohort study consisting of pregnancies that occurred during this time period. ICD-9 codes were used to identify delivery admissions to women with or without BD. Multivariate logistic regression was used to estimate the adjusted effects of BD on maternal and fetal outcomes. Results: Among the 12,592,676 pregnancies in our cohort, 144 were to women with BD, for an overall prevalence of 1.14 cases/100,000 births between 1999 and 2013. Over the study period, the prevalence of BD rose from 0.5 to 2.4/100,000 births. Women with BD demonstrated a two-fold greater frequency of non-delivery hospital admissions during pregnancy, and were more likely to be Caucasian, have private medical insurance, be of the upper income quartiles, and deliver at an urban teaching hospital. Women with BD were at greater risk for preterm labor and postpartum venous thromboembolism, while their newborns were more likely to be born premature. Conclusion: BD-associated pregnancies are increasing in prevalence and are associated with a greater risk for adverse maternal and fetal outcomes in pregnancy. Appropriate thromboprophylaxis during pregnancy should be considered given the increased risk for venous thromboembolism. [ABSTRACT FROM AUTHOR]
