Pregnancy and Neonatal Outcomes Following Prenatal Exposure to Dolutegravir.

ABSTRACT: BACKGROUND:Birth outcome data with dolutegravir exposure during pregnancy, particularly in the first trimester, are needed. SETTING:Data were prospectively collected from the Antiretroviral Pregnancy Registry and European Pregnancy and Paediatric HIV Cohort Collaboration. METHODS:We reviewed 2 large, independent antiretroviral pregnancy registries to assess birth outcomes associated with maternal dolutegravir treatment during pregnancy. RESULTS:Of 265 pregnancies reported to the Antiretroviral Pregnancy Registry, initial exposure to dolutegravir occurred at conception or first trimester in 173 pregnancies and during the second or third trimester in 92 pregnancies. There were 246 (92.8%) live births resulting in 255 neonates (9 twins), 6 (2.3%) induced abortions, 11 (4.2%) spontaneous abortions, and 2 (0.8%) stillbirths. Birth defects occurred in 7 (2.7%) of 255 live-born neonates, 5 (3.1%) of 162 (includes 6 twins) with conception/first-trimester exposure. Of 101 pregnancies reported to the European Pregnancy and Paediatric HIV Cohort Collaboration, outcomes were available for 84 pregnancies (16 continuing to term and 1 lost to follow-up). There were 81 live births (80 with known initial dolutegravir exposure at conception or first, second, and third trimesters in 42, 21, and 17 live births, respectively), 1 stillbirth (second-trimester exposure), 1 induced abortion (first-trimester exposure), and 1 spontaneous abortion (first-trimester exposure), respectively. Birth defects occurred in 4 live births (4.9%; 95% confidence interval: 1.4 to 12.2), 3 of 42 (7.1%) with exposure at conception or first trimester. CONCLUSIONS:Our findings are reassuring regarding dolutegravir treatment of HIV infection during pregnancy but remain inconclusive because of small sample sizes.

Project description:Background and objectivesThere is a lack of well-controlled US studies of intramuscular (IM) interferon beta (IFNβ)-1a use in pregnant women with multiple sclerosis; however, in the European Medicines Agency region, IFNβ formulations may be considered during pregnancy if clinically needed based on data from European Union cohort registries. The AVONEX Pregnancy Exposure Registry was established to prospectively study the effects of IM IFNβ-1a on the risk of birth defects and spontaneous pregnancy loss in a US population.MethodsPregnant women with multiple sclerosis exposed to IM IFNβ-1a within ~ 1 week of conception or during the first trimester were included. Participants were followed until there was a pregnancy outcome, live-born infants were followed until age 8-12 weeks. Data were collected on IM IFNβ-1a exposure, demographics, patient characteristics, medical history, and pregnancy outcomes, including live births (with or without birth defect), spontaneous abortions/miscarriages and fetal death/stillbirth, elective abortions (with and without birth defect), and ectopic pregnancies. A population-based birth defect surveillance program, the Metropolitan Atlanta Congenital Defects Program (MACDP), served as the primary external control group for evaluating the risk of birth defects.ResultsThree-hundred and two patients with a median (range) age of 31.0 (16-48) years and a median (range) gestational age at the time of enrollment of 10.1 (4-39) weeks were evaluable. Most patients (n = 278/302; 92%) reported IM IFNβ-1a exposure in the week before conception and most (n = 293/302; 97%) discontinued treatment before the end of the first trimester. Of 306 pregnancy outcomes, there were 272 live births, 28 spontaneous abortions of 266 pregnancies enrolled before 22 weeks' gestation (rate 10.5%; 95% confidence interval 7.2-15.0), five elective abortions, and one stillbirth. There were 17 adjudicator-confirmed major birth defects of 272 live births (rate 6.3%; 95% confidence interval 3.8-10.0); the pattern of birth defects observed was not suggestive of a relationship to prenatal IM IFNβ-1a exposure.ConclusionsThis large US registry study suggests IM IFNβ-1a exposure during early pregnancy was not clinically associated with adverse pregnancy outcomes in women with multiple sclerosis. These findings help inform clinicians and patients in weighing the risks and benefits of IM IFNβ-1a use during pregnancy.Clinical trial registrationClinicalTrials.gov: NCT00168714, 15 September, 2005.

Project description:OBJECTIVE:To evaluate the risk of adverse maternal and infant outcomes following in utero exposure to duloxetine. DESIGN:Cohort study nested in the Medicaid Analytic eXtract for 2004-13. SETTING:Publicly insured pregnancies in the United States. PARTICIPANTS:Pregnant women 18 to 55 years of age and their liveborn infants. INTERVENTIONS:Duloxetine exposure during the etiologically relevant time window, compared with no exposure to duloxetine, exposure to selective serotonin reuptake inhibitors, exposure to venlafaxine, and exposure to duloxetine before but not during pregnancy. MAIN OUTCOME MEASURES:Congenital malformations overall, cardiac malformations, preterm birth, small for gestational age infant, pre-eclampsia, and postpartum hemorrhage. RESULTS:Cohort sizes ranged from 1.3 to 4.1 million, depending on the outcome. The number of women exposed to duloxetine varied by cohort and exposure contrast and was around 2500-3000 for early pregnancy exposure and 900-950 for late pregnancy exposure. The base risk per 1000 unexposed women was 36.6 (95% confidence interval 36.3 to 36.9) for congenital malformations overall, 13.7 (13.5 to 13.9) for cardiovascular malformations, 107.8 (107.3 to 108.3) for preterm birth, 20.4 (20.1 to 20.6) for small for gestational age infant, 33.6 (33.3 to 33.9) for pre-eclampsia, and 23.3 (23.1 to 23.4) for postpartum hemorrhage. After adjustment for measured potential confounding variables, all baseline characteristics were well balanced for all exposure contrasts. In propensity score adjusted analyses versus unexposed pregnancies, the relative risk was 1.11 (95% confidence interval 0.93 to 1.33) for congenital malformations overall and 1.29 (0.99 to 1.68) for cardiovascular malformations. For preterm birth, the relative risk was 1.01 (0.92 to 1.10) for early exposure and 1.19 (1.04 to 1.37) for late exposure. For small for gestational age infants the relative risks were 1.14 (0.92 to 1.41) and 1.20 (0.83 to 1.72) for early and late pregnancy exposure, respectively, and for pre-eclampsia they were 1.12 (0.96 to 1.31) and 1.04 (0.80 to 1.35). The relative risk for postpartum hemorrhage was 1.53 (1.08 to 2.18). Results from sensitivity analyses were generally consistent with the findings from the main analyses. CONCLUSIONS:On the basis of the evidence available to date, duloxetine is unlikely to be a major teratogen but may be associated with an increased risk of postpartum hemorrhage and a small increased risk of cardiac malformations. While continuing to monitor the safety of duloxetine as data accumulate over time, these potential small increases in risk of relatively uncommon outcomes must be weighed against the benefits of treating depression and pain during pregnancy in a given patient.
