Oral corticosteroid use during pregnancy and risk of preterm birth.

ABSTRACT: OBJECTIVE:To evaluate the associations between oral corticosteroid (OCS) dose early and late in pregnancy and preterm birth (PTB) among women with RA. METHODS:Pregnant women in the MotherToBaby Pregnancy Studies (2003-2014) with RA (n = 528) were included in the primary analysis. Information was collected by phone interview and from medical records. We estimated risk ratios (RR) for OCS dose trajectories and other disease-related medications before gestational day 140 and hazard ratios (HR) for time-varying exposures after gestational day 139. RESULTS:PTB risk was 15.5% overall. Compared with no OCS, PTB risk was increased in high (adjusted (a)RR: 4.77 (95% CI: 2.76, 8.26)) and medium (aRR: 1.81 (95% CI: 1.10, 2.97)) cumulative OCS dose trajectories during the first 139 gestational days. The low cumulative trajectory group was associated with an increased risk of PTB that was not statistically significant (aRR: 1.38 (95% CI: 0.79, 2.38)), and DMARDs were not associated with PTB (biologic DMARDs aHR: 1.08 (95% CI: 0.70, 1.66); non-biologic DMARDs aHR: 0.87 (95% CI: 0.55, 1.38)). OCS exposure to ?10 mg of prednisone equivalent daily dose after gestational day 139 vs none was associated with increased PTB rate (aHR: 2.45 (95% CI: 1.32, 4.56)), whereas <10 mg was associated with a modestly increased rate of PTB that was not statistically significant (aHR: 1.18 (95% CI: 0.60, 2.30)). CONCLUSION:Higher OCS doses vs no OCS use, both earlier and later in pregnancy, were associated with an increase in PTB among women with RA.

Project description:BACKGROUND: The association between the risk of orofacial clefts in infants and the use of corticosteroids during pregnancy is unclear from the available evidence. We conducted a nationwide cohort study of all live births in Denmark over a 12-year period. METHODS: We collected data on all live births in Denmark from Jan. 1, 1996, to Sept. 30, 2008. We included live births for which information was available from nationwide health registries on the use of corticosteroids during pregnancy, the diagnosis of an orofacial cleft and possible confounders. RESULTS: There were 832,636 live births during the study period. Exposure to corticosteroids during the first trimester occurred in 51,973 of the pregnancies. A total of 1232 isolated orofacial clefts (i.e., cleft lip, cleft palate, or cleft lip and cleft palate) were diagnosed within the first year of life, including 84 instances in which the infant had been exposed to corticosteroids during the first trimester of pregnancy. We did not identify any statistically significant increased risk of orofacial clefts associated with the use of corticosteroids: cleft lip with or without cleft palate, prevalence odds ratio (OR) 1.05 (95% confidence interval [CI] 0.80-1.38]; cleft palate alone, prevalence OR 1.23 (95% CI 0.83-1.82). Odds ratios for risk of orofacial clefts by method of delivery (i.e., oral, inhalant, nasal spray, or dermatologic and other topicals) were consistent with the overall results of the study and did not display significant heterogeneity, although the OR for cleft lip with or without cleft palate associated with the use of dermatologic corticosteroids was 1.45 (95% CI 1.03-2.05). INTERPRETATION: Our results add to the safety information on a class of drugs commonly used during pregnancy. Our study did not show an increased risk of orofacial clefts with the use of corticosteroids during pregnancy. Indepth investigation of the pattern of association between orofacial clefts and the use of dermatologic corticosteroids during pregnancy indicated that this result did not signify a causal connection and likely arose from multiple statistical comparisons.

Project description:BackgroundPreterm birth (PTB), a leading cause of infant mortality and morbidity, has a complex etiology with a multitude of interacting causes and risk factors. The role of environmental contaminants, particularly bisphenol A (BPA), is understudied with regard to PTB.ObjectivesIn the present study we examined the relationship between longitudinally measured BPA exposure during gestation and PTB.MethodsA nested case-control study was performed from women enrolled in a prospective birth cohort study at Brigham and Women's Hospital in Boston, Massachusetts, during 2006-2008. Urine samples were analyzed for BPA concentrations at a minimum of three time points during pregnancy on 130 cases of PTB and 352 randomly assigned controls. Clinical classifications of PTB were defined as "spontaneous," which was preceded by spontaneous preterm labor or preterm premature rupture of membranes, or "placental," which was preceded by preeclampsia or intrauterine growth restriction.ResultsGeometric mean concentrations of BPA did not differ significantly between cases and controls. In adjusted models, urinary BPA averaged across pregnancy was not significantly associated with PTB. When examining clinical classifications of PTB, urinary BPA late in pregnancy was significantly associated with increased odds of delivering a spontaneous PTB. After stratification on infant's sex, averaged BPA exposure during pregnancy was associated with significantly increased odds of being delivered preterm among females, but not males.ConclusionsThese results provide little evidence of a relationship between BPA and prematurity, though further research may be warranted given the generalizability of participant recruitment from a tertiary teaching hospital, limited sample size, and significant associations among females and within the clinical subcategories of PTB.CitationCantonwine DE, Ferguson KK, Mukherjee B, McElrath TF, Meeker JD. 2015.

Project description:ObjectiveTo describe discordance in antenatal corticosteroid use and resuscitation following extremely preterm birth and its relationship with infant survival and neurodevelopment.Study designA multicenter cohort study of 4858 infants 22-26 weeks of gestation born 2006-2011 at 24 US hospitals participating in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network, with follow-up through 2013. Survival and neurodevelopmental outcomes were available at 18-22 months of corrected age for 4576 (94.2%) infants. We described antenatal interventions, resuscitation, and infant outcomes. We modeled the effect on infant outcomes of each hospital increasing antenatal corticosteroid exposure for resuscitated infants born at 22-24 weeks of gestation to rates observed at 25-26 weeks of gestation.ResultsDiscordant antenatal corticosteroid use and resuscitation, where one and not the other occurred, were more frequent for births at 22 and 23 but not 24 weeks (rate ratio [95% CI] at 22 weeks: 1.7 [1.3-2.2]; 23 weeks: 2.6 [2.2-3.2]; 24 weeks: 1.0 [0.8-1.2]) when compared with 25-26 weeks. Among infants resuscitated at 23 weeks, adjusting each hospital's rate of antenatal corticosteroid use to the average at 25-26 weeks (89.2%) was projected to increase infant survival by 7.1% (95% CI 5.4-8.8%) and survival without severe impairment by 6.4% (95% CI 4.7-8.1%). No significant change in outcomes was projected for infants resuscitated at 22 weeks, where few (n = 22) resuscitated infants received antenatal corticosteroids.ConclusionsInfants born at 23 weeks were more frequently resuscitated without antenatal corticosteroids than other extremely preterm infants. When resuscitation is intended, consistent provision of antenatal corticosteroids may increase infant survival and survival without impairment.Trial registrationClinicalTrials.govNCT00063063 (Generic Database) and NCT00009633 (Follow-Up Study).

Project description:BACKGROUND:Pregnant women with a history of preterm birth are at risk for recurrence, often requiring frequent prenatal visits for close monitoring and/or preventive therapies. Employment demands can limit uptake and adherence to recommended monitoring and preterm birth prevention therapies. METHOD:We conducted a qualitative descriptive study using in-depth interviews (IDIs) of pregnant women with a history of preterm birth. IDIs were conducted by trained qualitative interviewers following a semi-structured interview guide focused on uncovering barriers and facilitators to initiation of prenatal care, including relevant employment experiences, and soliciting potential interventions to improve prompt prenatal care initiation. The IDIs were analyzed via applied thematic analysis. RESULTS:We described the interview findings that address women's employment experiences. The current analysis includes 27 women who are majority self-described as non-Hispanic Black (74%) and publically insured (70%). Participants were employed in a range of professions; food services, childcare and retail were the most common occupations. Participants described multiple ways that being pregnant impacted their earning potential, ranging from voluntary work-hour reduction, involuntary duty hour reductions by employers, truncated promotions, and termination of employment. Participants also shared varying experiences with workplace accommodations to their work environment and job duties based on their pregnancy. Some of these accommodations were initiated by a collaborative employee/employer discussion, others were initiated by the employer's perception of safe working conditions in pregnancy, and some accommodations were based on medical recommendations. Participants described supportive and unsupportive employer reactions to requests for accommodations. CONCLUSIONS:Our findings provide novel insights into women's experiences balancing a pregnancy at increased risk for preterm birth with employment obligations. While many women reported positive experiences, the most striking insights came from women who described negative situations that ranged from challenging to potentially unlawful. Many of the findings suggest profound misunderstandings likely exist at the patient, employer and clinical provider level about the laws surrounding employment in pregnancy, safe employment responsibilities during pregnancy, and the range of creative accommodations that often allow for continued workplace productivity even during high risk pregnancy.
