Bipolar disorder in the postpartum period: the impact of a prenatal mood episode on maternal improvement at postpartum discharge after joint inpatient hospitalization.

Bipolar disorder (BD) is linked to a high risk of relapse in the year postpartum. The aim of this study was to search for an association of a mood episode during pregnancy with a lack of maternal improvement after a post-partum episode requiring joint hospitalization. In an observational, naturalist, and multicentric study, 261 women suffering from a BD and jointly hospitalized with their child in a Mother-Baby Unit (MBU) were assessed for risk factors associated with a lack of maternal improvement at discharge. A directed acyclic graph (DAG)-based approach was used to identify confounders to be included in a multiple regression model. In bivariate analyses, a lack of improvement (16.9%) was associated with pregnancy specificities (decompensation, psychotropic treatment, antipsychotics, and benzodiazepines intake), as well as maternal smoking during pregnancy and baby's neonatal hospitalization. In a multivariate analysis based on DAG, a lack of improvement was linked to psychiatric decompensation during pregnancy (OR = 3.31, 95%CI [1.55-7.35], p = 0.002), independently from maternal age, mother's maltreatment during childhood, low level of education, single status, low familial social support, and diagnosis of personality disorder. This study shows the critical importance of mental health during pregnancy in women with BD. Clinical screening and evaluation of the benefit/risk balance of psychotropics during pregnancy are essential.

Risk for Autism Spectrum Disorders According to Period of Prenatal Antidepressant Exposure: A Systematic Review and Meta-analysis.

Importance: Several studies have examined the links between prenatal exposure to antidepressants and autism spectrum disorders (ASDs) in children, with inconsistent results, especially regarding the impact of the trimester of exposure. Objective: To perform a systematic review of the literature and a meta-analysis of published studies to assess the association between ASDs and fetal exposure to antidepressants during pregnancy for each trimester of pregnancy and preconception. Data Sources: PubMed, EMBASE, and PsycINFO databases up to May 2016 were searched in June 2016 for observational studies. For the meta-analyses, data were analyzed on RevMan version 5.2 using a random-effect model. For the review, studies were included if they had been published and were cohort or case-control studies, and for the meta-analysis, studies were included if they were published studies and the data were not derived from the same cohorts. Study Selection: We included all the studies that examined the association between ASDs and antenatal exposure to antidepressants. Data Extraction and Synthesis: Three reviewers independently screened titles and abstracts, read full-text articles, and extracted data. The quality of the studies was also assessed. Main Outcomes and Measures: Primary outcome was the association between antidepressants during pregnancy and ASDs. Secondary outcomes were the associations between antidepressants in each individual trimester or before pregnancy and ASDs. Results: Our literature search identified 10 relevant studies with inconsistent results. For prenatal exposure, the meta-analysis on the 6 case-control studies (117 737 patients) evidenced a positive association between antidepressant exposure and ASDs (odds ratio [OR], 1.81; 95% CI, 1.49-2.20). The association was weaker when controlled for past maternal mental illness (OR, 1.52; 95% CI, 1.09-2.12). A similar pattern was found whatever the trimester of exposure considered (first trimester: OR, 2.09, 95% CI,1.66-2.64; second: OR, 2.00, 95% CI, 1.55-2.59; and third: OR, 1.90, 95% CI, 1.20-3.02. Controlled for past maternal mental illness: first trimester: OR, 1.79; 95% CI, 1.27-2.52, second: OR, 1.67, 95% CI, 1.14-2.45; and third: OR, 1.54, 95% CI, 0.82-2.90). No association was found when the 2 cohort studies were pooled (772 331 patients) for the whole pregnancy (hazard ratio, 1.26; 95% CI, 0.91-1.74) or for the first trimester. In addition, preconception exposure to antidepressants was significantly associated with an increased risk for ASDs (OR controlled for past maternal illness, 1.77; 95% CI, 1.49-2.09). Conclusions and Relevance: There is a significant association between increased ASD risk and maternal use of antidepressants during pregnancy; however, it appears to be more consistent during the preconception period than during each trimester. Maternal psychiatric disorders in treatment before pregnancy rather than antenatal exposure to antidepressants could have a major role in the risk for ASDs. Future studies should address the problem of this potential confounder.
