BackgroundMajor depressive disorder during pregnancy associates with potentially detrimental consequences for mother and child. The current study examined peripheral blood gene expression as a potential biomarker for prenatal depressive symptoms.MethodMaternal RNA from whole blood, plasma and the Beck Depression Inventory were collected longitudinally from preconception through the third trimester of pregnancy in 106 women with a lifetime history of mood or anxiety disorders. The expression of 16 genes in whole blood involved in glucorticoid receptor (GR) signaling was assessed using real-time polymerase chain reaction. In parallel, plasma concentrations of progesterone, estradiol and cortisol were measured. Finally, we assessed ex vivo GR sensitivity in peripheral blood cells from a subset of 29 women.ResultsmRNA expression of a number of GR-complex regulating genes was up-regulated over pregnancy. Women with depressive symptoms showed significantly smaller increases in mRNA expression of four of these genes – FKBP5, BAG1, NCOA1 and PPID. Ex vivo stimulation assays showed that GR sensitivity diminished with progression of pregnancy and increasing maternal depressive symptoms. Plasma concentrations of gonadal steroids and cortisol did not differ over pregnancy between women with and without clinically relevant depressive symptoms.ConclusionsThe presence of prenatal depressive symptoms appears to be associated with altered regulation of GR sensitivity. Peripheral expression of GR co-chaperone genes may serve as a biomarker for risk of developing depressive symptoms during pregnancy. The presence of such biomarkers, if confirmed, could be utilized in treatment planning for women with a psychiatric history. [ABSTRACT FROM PUBLISHER]

Objective Outcome investigations of prenatal maternal depression and psychotropic exposure rely extensively on maternal retrospective recall. This study compared postnatal recall to prospective documentation of illness and medication exposures. Design Prospective cohort and retrospective case–control studies. Setting Emory Women’s Mental Health Program (prospective study) and Emory University Department of Psychology (retrospective study). Sample A total of 164 women who participated in both the prospective and retrospective studies. Methods Women with a history of mental illness were followed during pregnancy for prospective prenatal assessments of depression and medication exposures. At 6 months postpartum, some of these women also participated in a retrospective study during which they were asked to recall prenatal depression and medication use. Agreement between prospective and retrospective documentation of exposures was analysed. Main outcome measures Occurrence of maternal depression during pregnancy and maternal use of pharmacological agents during pregnancy. Results There was only moderate agreement ( k = 0.42) in prospective versus retrospective reporting of prenatal depression. Positive predictive value for recalling depression was 90.4%; however, negative predictive value for denying depression was only 53.8%. Participants accurately recalled psychotropic use but significantly underreported use of nonpsychotropic medications. Conclusions Studies using retrospective data collection may be susceptible to systematic recall bias with underreporting of maternal depression and use of nonpsychotropic agents during pregnancy.

The objectives of this study were 1) to determine the prevalence of suicidal ideation (SI) in pregnant women with a history of neuropsychiatric illness, 2) to assess the relative sensitivity of commonly used depression rating scales for detecting SI, and 3) to examine the sociodemographic and clinical predictors of SI in pregnant women. Demographic data, Beck Depression Inventory [BDI] and Hamilton Rating Scale for Depression [HRSD] questionnaires, and SCID interviews were obtained from 383 pregnant women presenting to the Emory Women’s Mental Health Program or the Emory Women’s Epilepsy Program. Among those who completed both scales, 29.2% endorsed SI on the BDI and 16.9% on the HRSD, with 33.0% endorsing SI on at least one of the rating scales and 13.1% on both rating scales. The rate of SI endorsement on the BDI was 73.3% higher than the HRSD. Multivariate logistic regression demonstrated that SI in pregnant women was associated with unplanned pregnancy (OR = 2.97), current major depression (OR = 4.12), and comorbid anxiety disorder (OR = 4.17). Further studies are warranted to identify additional predictors of perinatal suicidality and to clarify the nature of the association between such factors and the presence of SI in pregnant women.

Objective:Pregnancy has frequently been referred to as a time of emotional well-being for patients. However, systematic data about the risk for relapse of depression during pregnancy are sparse.Method:We completed a longitudinal cohort study of thirty-two (N?=?32) women with histories of depression who were euthymic at conception and who either discontinued or attempted to discontinue antidepressant therapy proximate to conception. Subjects were prospectively followed across pregnancy once per trimester using structured clinical interviews. Rates of relapse and time to relapse were examined. Factors distinguishing the population with respect to risk for relapse including demographic characteristics and illness history were also examined.Results:Seventy-five percent (N?=?24) of patients relapsed during pregnancy. The majority of relapses (79%, N?=?19) occurred in the first trimester, and relapse was more prevalent in women with histories of more chronic depression.Conclusions:Pregnancy is not “protective” with respect to risk for relapse of depression. Careful treatment planning is necessary for those women on antidepressants who plan to conceive or who become pregnant. [ABSTRACT FROM AUTHOR]

This study tests the hypothesis that maternal depression during pregnancy predicts temperament in offspring aged 6 m to 5 y. Previous studies have shown that maternal depression is related to negative affect and that certain temperament factors, such as negative affect and behavioral inhibition, in children predict affective disorders. Here, maternal depression is divided into depression during pregnancy vs. depression postpartum. Maternal depression was determined by the Beck Depression Inventory (BDI) throughout pregnancy and postpartum (prospectively) and by a diagnostic interview (SCID) at 6 months postpartum. The data show that maternal depression during pregnancy, but not postpartum, predicted the ratings of negative affect in the offspring. Importantly, symptoms of depression in the mother (BDI) were used as a control variable in the analyses in order to control for potential bias related to the mother's mood. In addition, cortisol levels in response to a mild stressor at 6 months of age predicted negative affect in infants and toddlers. We conclude that the effects of maternal depression on behavioral problems and vulnerability to mental illness may be mediated by altered temperament and enhanced stress responsiveness.
