Project description:Intrahepatic cholestasis of pregnancy (ICP) has important fetal implications. There is increased risk for poor fetal outcomes, including preterm delivery, meconium staining of amniotic fluid, respiratory distress, fetal distress and demise.One hundred and one women diagnosed with ICP between January 2005 and March 2009 at San Francisco General Hospital were included in this study. Single predictor logistic regression models were used to assess the associations of maternal clinical and biochemical predictors with fetal complications. Clinical predictors analyzed included age, race/ethnicity, gravidity, parity, history of liver or biliary disease, history of ICP in previous pregnancies, and induction. Biochemical predictors analyzed included serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilirubin, direct bilirubin, albumin, total protein, and total bile acids (TBA).The prevalence of ICP was 1.9%. Most were Latina (90%). Labor was induced in the majority (87%) and most were delivered by normal spontaneous vaginal delivery (84%). Fetal complications occurred in 33% of the deliveries, with respiratory distress accounting for the majority of complications. There were no statistically significant clinical or biochemical predictors associated with an increased risk of fetal complications. Elevated TBA had little association with fetal complications until reaching greater than 100 µmoL/L, with 3 out of 5 having reported complications. ICP in previous pregnancies was associated with decreased risk of fetal complications (OR 0.21, p = 0.046). There were no cases of late term fetal demise.Maternal clinical and laboratory features, including elevated TBA, did not appear to be substantial predictors of fetal complications in ICP.

Project description:Purpose:This study aimed to analyze the clinicopathological features, treatment, and feto-maternal outcomes of pregnancy complicated by malignant ovarian germ cell tumors (MOGCTs), to increase the awareness on this condition. Patients and Methods:We retrospectively reviewed the medical records of patients diagnosed with MOGCTs during pregnancy, who were treated and followed-up at Peking Union Medical College Hospital from January 2000 to December 2017. The demographic characteristics, pathological features, treatment and prognosis were analyzed. Results:The histological subtypes varied in 14 patients (dysgerminoma, n=1; immature teratoma, n=4; yolk sac tumor, n=6; and mixed germ cell tumors, n=3). Ten (71.4%) patients, including three who opted for conservative therapy until childbirth, one who only received salvage chemotherapy during pregnancy, and six who underwent cystectomy or unilateral salpingo-oophorectomy during pregnancy, desired fetal preservation. After undergoing surgery, four patients chose surveillance instead of timely adjuvant chemotherapy. Eight patients delivered their babies, and the preterm delivery rate was 50.0%. One newborn died of premature birth. The median follow-up period was 44 (range: 13 to 86) months. During the current study period, 12 patients had survived and did not report any diseases. However, two died due to disease progression. Conclusion:Pregnant women with MOGCTs had favorable outcomes. However, when a malignant tumor is suspected, surgery cannot be avoided. Thus, instead of timely postoperative adjuvant chemotherapy, close surveillance may be an acceptable alternative for pregnant women with low-risk MOGCTs.

Project description:Fetal digestive system malformations (DSMs) are correlated with chromosomal anomalies. The prenatal diagnosis of DSMs allows for timely treatment and reduces perinatal morbidity and mortality. However, genetic screening for fetal DSMs is rarely reported. This study aimed to investigate genetic etiology and pregnancy outcomes in cases of fetal DSM by analyzing correlations between DSM types and chromosomal anomalies. This retrospective single-center study included 126 fetuses in whom DSMs were detected via prenatal ultrasonography. Genetic etiology was investigated using conventional karyotyping, chromosome microarray analysis (CMA), and whole-exome sequencing (WES). DSMs were categorized as simple DSM (Group A), DSM combined with abnormal ultrasound soft markers (Group B), and DSM combined with comorbidities of other systems (Group C). Abnormal karyotypes were detected in 11/126 (8.7 %) fetuses. Four more pathogenic copy number variants (CNVs) were detected using CMA, increasing the detection rate to 11.9 %. The detection rates significantly differed between the three DSM types (1.78 %, 8.11 %, and 33.33 % in Groups A, B, and C, respectively). The overall adverse pregnancy outcome rate was 33.9 %, and 11.5 %, 23.5 %, and 81.3 %, (P < 0.001), respectively, in Groups A, B, and C. Out of 83 live births, three neonates died, 26 underwent postnatal surgery with 24 favorable outcomes, and 54 did not undergo surgery and were basically normal. Two neonates who underwent WES were diagnosed with CHD7-associated Charge syndrome and JAG1-associated Alagille syndrome, respectively. Our findings demonstrate that fetal DSM is closely related to chromosome aneuploidies, CNVs, and point mutations. The prognoses of most fetuses with simple DSM and those with comorbid abnormal ultrasound soft markers were favorable in the absence of chromosomal anomalies and severe structural malformations, provided they underwent timely surgery as neonates. These findings provide guidance for the prenatal diagnosis and clinical management of fetal DSMs and the genetic counseling of parents.

Project description:ImportanceThe management of lymphoma diagnosed during pregnancy is controversial and has been guided largely by findings from case reports and small series.ObjectiveTo determine maternal and fetal outcomes of women diagnosed with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) during pregnancy.Design, setting, and participantsThis retrospective analysis studied a cohort of 39 pregnant women diagnosed with HL and NHL (31 HL and 8 NHL) at a single specialized cancer institution between January 1991 and December 2014.Main outcomes and measuresWe examined data on disease and treatment characteristics, as well as maternal and fetal complications and outcomes. The Kaplan-Meier method was used to compare progression free survival (PFS) and overall survival (OS) according to receipt of antenatal therapy and other clinical factors. Univariate and multivariate analyses were performed by using Cox proportional hazard regression models to identify potential associations between clinical and treatment factors and survival.ResultsThe median (range) age of the 39 women in the patient cohort was 28 (19-38) years; 32 women (82%) had stage I or II disease at diagnosis, and 13 had bulky disease. Three women electively terminated the pregnancy to allow immediate systemic therapy; of the remaining 36 women, 24 received antenatal therapy (doxorubicin based combination chemotherapy in 20 of 24 patients), and 12 deferred therapy until after delivery. Four women experienced miscarriage, all of whom had received antenatal systemic therapy and 2 during the first trimester. Delivery occurred at a median (range) of 37 (32-42) weeks and was no different based on receipt of antenatal (median [range], 37 [33-42] weeks) vs postnatal (median [range], 37 [32-42] weeks) therapy (P = .21). No gross fetal malformations or anomalies were detected. At a median (range) follow-up time of 67.9 (8.8-277.5) months since the diagnosis of lymphoma, 5-year rates of PFS and OS were 74.7% and 82.4%, respectively; these rates did not differ according to timing of therapy. On univariate analysis, bulky disease (>10 cm), extranodal nonbone marrow involvement, and poor performance status (Eastern Cooperative Oncology Group score, ≥2) predicted increased risk of disease progression. On multivariate analysis, extranodal nonbone marrow disease and performance status remained significant for both PFS and OS.Conclusions and relevanceSystemic therapy given for lymphoma after the first trimester of pregnancy is likely safe and results in acceptable maternal and fetal outcomes.

Project description:Adequate iron supply during pregnancy is essential for fetal development. However, how fetal or amniotic fluid iron levels are regulated during healthy pregnancy, or pregnancies complicated by intraamniotic infection or inflammation (IAI), is unknown. We evaluated amniotic fluid and fetal iron homeostasis in normal and complicated murine, macaque, and human pregnancy. In mice, fetal iron endowment was affected by maternal iron status, but amniotic fluid iron concentrations changed little during maternal iron deficiency or excess. In murine and macaque models of inflamed pregnancy, the fetus responded to maternal systemic inflammation or IAI by rapidly upregulating hepcidin and lowering iron in fetal blood, without altering amniotic fluid iron. In humans, elevated cord blood hepcidin with accompanying hypoferremia was observed in pregnancies with antenatal exposure to IAI compared with those that were nonexposed. Hepcidin was also elevated in human amniotic fluid from pregnancies with IAI compared with those without IAI, but amniotic fluid iron levels did not differ between the groups. Our studies in mice, macaques, and humans demonstrate that amniotic fluid iron is largely unregulated but that the rapid induction of fetal hepcidin by inflammation and consequent fetal hypoferremia are conserved mechanisms that may be important in fetal host defense.

Project description:Pregnancy in kidney disease is considered high risk, but the degree of this risk is unclear. We tested the hypothesis that kidney disease in pregnancy is associated with adverse maternal and fetal outcomes.Retrospective study comparing pregnant women with and without kidney disease.Using data from an integrated health care delivery system from 2000 through 2013, a total of 778 women met the criteria for kidney disease. Using a pool of 74,105 women without kidney disease, we selected 778 women to use for matches for the women with kidney disease. These women were matched 1:1 by age, race, and history of diabetes, chronic hypertension, liver disease, and connective tissue disease.Kidney disease was defined using the NKF-KDOQI definition for chronic kidney disease or International Classification of Diseases, Ninth Revision codes prior to pregnancy or serum creatinine level > 1.2mg/dL and/or proteinuria in the first trimester.Maternal outcomes included preterm delivery, delivery by cesarean section, preeclampsia/eclampsia, length of stay at hospital (>3 days), and maternal death. Fetal outcomes included low birth weight (weight < 2,500g), small for gestational age, number of admissions to neonatal intensive care unit, and infant death.Compared with women without kidney disease, those with kidney disease had 52% increased odds of preterm delivery (OR, 1.52; 95% CI, 1.16-1.99) and 33% increased odds of delivery by cesarean section (OR, 1.33; 95% CI, 1.06-1.66). Infants born to women with kidney disease had 71% increased odds of admission to the neonatal intensive care unit or infant death compared with infants born to women without kidney disease (OR, 1.71; 95% CI, 1.17-2.51). Kidney disease also was associated with 2-fold increased odds of low birth weight (OR, 2.38; 95% CI, 1.64-3.44). Kidney disease was not associated with increased risk of maternal death.Data for level of kidney function and cause of death not available.Kidney disease in pregnancy is associated independently with adverse maternal and fetal outcomes when other comorbid conditions are controlled by matching.

Project description:ImportanceFexofenadine hydrochloride is a frequently used drug for treatment of allergic conditions during pregnancy, but the fetal safety of fexofenadine use has not been well studied.ObjectiveTo investigate the risk of adverse fetal outcomes associated with fexofenadine use during pregnancy.Design, setting, and participantsA nationwide registry-based cohort study was conducted on pregnancies in Denmark from January 1, 2001, to December 31, 2016. Data analysis was performed from March 21, 2019, to January 29, 2020. From a cohort of 1 287 668 pregnancies, fexofenadine use was compared with cetirizine hydrochloride use during pregnancy, matched in a 1:1 ratio on propensity scores. Distinct study cohorts and exposure time periods were applied according to each outcome analysis. Sensitivity analyses included comparing pregnancies with vs without fexofenadine exposure during pregnancy but with previous use before pregnancy and with loratadine use during pregnancy as additional comparator groups.ExposureFilled prescription for fexofenadine.Main outcomes and measuresMajor birth defects and spontaneous abortion. Secondary outcomes were preterm birth, small size for gestational age (SGA), and stillbirth. Logistic regression was used to estimate prevalence odds ratios (ORs) of major birth defects, preterm birth, and SGA, and Cox proportional hazards regression was used to estimate hazard ratios (HRs) of spontaneous abortion and stillbirth.ResultsFor the analyses of major birth defects and spontaneous abortion, a total of 2962 and 4901 pregnancies with fexofenadine use were included, respectively, matched in a 1:1 ratio with pregnancies with cetirizine use. Mean (SD) age of the fexofenadine cohort for analyses of major birth defects was 30.6 (4.8) years and, for analysis of spontaneous abortion, 30.4 (5.5) years. Infants born with major birth defects occurred in 118 pregnancies (4.0%) with fexofenadine use compared with 112 pregnancies (3.8%) with cetirizine use. Spontaneous abortion occurred in 413 pregnancies (8.4%) with fexofenadine use compared with 439 pregnancies (9.0%) with cetirizine use. Fexofenadine use during pregnancy was not associated with an increased risk of major birth defects (prevalence OR, 1.06; 95% CI, 0.81-1.37) or spontaneous abortion (HR, 0.93; 95% CI, 0.82-1.07) compared with cetirizine use during pregnancy. Preterm birth occurred in 370 pregnancies (7.5%) with fexofenadine use compared with 382 pregnancies (7.7%) with cetirizine use (prevalence OR, 0.97; 95% CI, 0.83-1.12), SGA occurred in 515 pregnancies (10.1%) with fexofenadine use compared with 523 pregnancies (10.2%) with cetirizine use (prevalence OR, 0.98; 95% CI, 0.87-1.12), and a total of 16 pregnancies (0.3%) with fexofenadine use ended in stillbirth compared with 24 pregnancies (0.4%) with cetirizine use (HR, 0.67; 95% CI, 0.36-1.27). Sensitivity analyses of the primary outcomes, including the comparisons of pregnancies with loratadine use and pregnancies unexposed to fexofenadine during pregnancy but with prior use of fexofenadine, showed similar results.Conclusions and relevanceUse of fexofenadine during pregnancy does not appear to be associated with an increased risk of adverse fetal outcomes.

Project description:ObjectiveTo provide outcome data concerning pregnancies exposed to the Interleukin-1 (IL-1) inhibitors prior to conception in both men and women, during pregnancy and breast feeding.MethodsRetrospective data were collected from members of the International Society for Systemic Autoinflammatory diseases and collated in a single centre. A uniform data collection sheet was used to obtain standardized data including maternal age and diagnosis, type, duration of and response to IL-1 blockade, pregnancy duration, delivery, mode of feeding and neonatal development.ResultsThere were 31 maternal-exposed pregnancies from seven countries and we report the first data on paternal exposure: six to anakinra and five to canakinumab, with no negative outcomes. We also report the first data on canakinumab-exposed pregnancies: eight pregnancies that resulted in the delivery of seven healthy infants of normal gestational age and birthweight. There were 23 anakinra-exposed pregnancies resulting in the birth of 21 healthy infants, and one baby with unilateral renal agenesis and ectopic neurohypophysis. There were two first trimester miscarriages affecting a mother with active disease. There were no serious neonatal infections. Fourteen infants were breast fed with no complications. There were no reports of developmental delay, with follow-up of up to 10 years (median 18 months).ConclusionThis series substantially increases the published experience of IL-1 blockade and reproduction including the first data on canakinumab and on paternal exposure to these agents. Data are generally reassuring, although the case of renal agenesis is the second reported in an anakinra-exposed pregnancy.

Project description:BACKGROUND:Investigations of the association of combination antiretroviral therapy (ART) with pregnancy outcomes often rely on routinely collected clinical data, which are prone to missing data and measurement error. Measurement error in gestational age may bias the relation between combination ART and gestational age-based outcomes. METHODS:We demonstrate the use of multiple overimputation to address missing data and measurement error in gestational age. Using routinely collected clinical data from public health facilities in Lusaka, Zambia, we multiply imputed missing data and multiply overimputed observed values of gestational age. Poisson models with robust variance estimators were used to estimate risk ratios (RRs) for the associations of duration of combination ART with small for gestational age (SGA) and preterm birth. We compared results from a complete-case analysis, using multiple imputation to address missing data only and using multiple overimputation to address missing data and measurement error. RESULTS:In the complete-case analysis, there was no evidence of an association between duration of combination ART and SGA or preterm birth. When we performed multiple overimputation, RRs for SGA moved past the null, but remained imprecise. For preterm birth, RRs for 9-32 weeks of combination ART moved away from the null as the variance due to measurement error increased. CONCLUSION:When we used multiple overimputation to account for measurement error and missing data, we observed an increased risk of preterm birth with longer duration of combination ART. Future analyses examining associations between combination ART and pregnancy outcomes should consider using multiple overimputation to address measurement error in gestational age.

Project description:ImportanceStillbirth is a devastating pregnancy outcome with far-reaching economic and psychosocial consequences, but despite significant investment, a screening tool for identifying those fetuses at risk for stillbirth remains elusive. Maternal reporting of decreased fetal movements (DFM) has been found to be associated with stillbirth and other adverse perinatal outcomes.ObjectiveTo examine pregnancy outcomes of women presenting with DFM in the third trimester at a tertiary Australian center with a clear clinical management algorithm.Design, setting, and participantsThis cohort study used data on all births meeting the inclusion criteria from 2009 through 2019 at Mater Mothers' Hospital in Brisbane, Australia. This is a tertiary center and Australia's largest maternity hospital. All singleton births without a known congenital anomaly after 28 weeks' gestation were included. Among 203 071 potential participants identified from the hospital database, 101 597 individuals met the eligibility criteria. Data analysis was performed from May through September 2020.ExposurePresentation to hospital with DFM after 28 weeks gestation.Main outcomes and measuresThe primary outcome of this study was the incidence of stillbirth. Multivariate analysis was undertaken to determine the association between DFM and stillbirth, obstetric intervention, and other adverse outcomes, including being born small for gestational age (SGA) and a composite adverse perinatal outcome (at least 1 of the following: neonatal intensive care unit admission, severe acidosis [ie, umbilical artery pH <7.0 or base excess -12.0 mmol/L or less], 5-minute Apgar score <4, or stillbirth or neonatal death). The hypothesis being tested was formulated prior to data collection.ResultsAmong 101 597 women with pregnancies that met the inclusion criteria, 8821 (8.7%) presented at least once with DFM and 92 776 women (91.3%) did not present with DFM (ie, the control population). Women presenting with DFM, compared with those presenting without DFM, were younger (mean [SD] age, 30.4 [5.4] years vs 31.5 [5.2] years; P < .001), more likely to be nulliparous (4845 women [54.9%] vs 42 210 women [45.5%]; P < .001) and have a previous stillbirth (189 women [2.1%] vs 1156 women [1.2%]; P < .001), and less likely to have a previous cesarean delivery (1199 women [13.6%] vs 17 444 women [18.8%]; P < .001). During the study period, the stillbirth rate was 2.0 per 1000 births after 28 weeks' gestation. Presenting with DFM was not associated with higher odds of stillbirth (9 women [0.1%] vs 185 women [0.2%]; adjusted odds ratio [aOR], 0.54; 95% CI, 0.23-1.26, P = .16). However, presenting with DFM was associated with higher odds of a fetus being born SGA (aOR, 1.14; 95% CI, 1.03-1.27; P = .01) and the composite adverse perinatal outcome (aOR, 1.14; 95% CI, 1.02-1.27; P = .02). Presenting with DFM was also associated with higher odds of planned early term birth (aOR, 1.26; 95% CI, 1.15-1.38; P < .001), induction of labor (aOR, 1.63; 95% CI, 1.53-1.74; P < .001), and emergency cesarean delivery (aOR, 1.18; 95% CI, 1.09-1.28; P < .001).Conclusions and relevanceThe presence of DFM is a marker associated with increased risk for a fetus. This study's findings of a nonsignificantly lower rate of stillbirth among women with DFM may be reflective of increased community awareness of timely presentation to their obstetric care clinician when concerned about fetal movements and the benefits of tertiary level care guided by a clear clinical management protocol. However, DFM was associated with increased odds of an infant being born SGA, obstetric intervention, early term birth, and a composite of adverse perinatal outcomes.
