Randomized dose-ranging pilot trial of omega-3 fatty acids for postpartum depression.

OBJECTIVE: Postpartum depression (PPD) affects 10-15% of mothers. Omega-3 fatty acids are an intriguing potential treatment for PPD. METHOD: The efficacy of omega-3 fatty acids for PPD was assessed in an 8-week dose-ranging trial. Subjects were randomized to 0.5 g/day (n = 6), 1.4 g/day (n = 3), or 2.8 g/day (n = 7). RESULTS: Across groups, pretreatment Edinburgh Postnatal Depression Scale (EPDS) and Hamilton Rating Scale for Depression (HRSD) mean scores were 18.1 and 19.1 respectively; post-treatment mean scores were 9.3 and 10.0. Percent decreases on the EPDS and HRSD were 51.5% and 48.8%, respectively; changes from baseline were significant within each group and when combining groups. Groups did not significantly differ in pre- or post-test scores, or change in scores. The treatment was well tolerated. CONCLUSION: This study was limited by small sample size and lack of placebo group. However, these results support further study of omega-3 fatty acids as a treatment for PPD.

Lesbian perinatal depression and the heterosexism that affects knowledge about this minority population.

The medical literature about homosexuality and mental health is expanding; however, a paucity of research about lesbian mental health remains. No research about lesbian perinatal depression has been published. This paper highlights the heterosexism that perpetuates research and health care disparities between heterosexual and lesbian/gay/bisexual individuals. We acknowledge barriers that distance lesbian women from research and health care, and emphasize the importance of moving beyond these barriers to fill in gaps of knowledge about the specific health care needs of this minority population. We use an analysis of stress factors as a framework to generate hypotheses about perinatal depression in lesbian women. We conclude with suggestions for future study in the form of questions that should be asked and pursued in research.

Psychiatric disorders during pregnancy.

Treating women with psychiatric disorders during pregnancy is a challenge for numerous reasons. Balancing the risks and benefits of symptoms and treatments is particularly important during pregnancy because both medication and maternal illness may have adverse effects on the fetus. Communication of options in the management of psychiatric disorders in pregnancy is vital to optimal treatment. One barrier to effective communication has been a paucity of research from which clinicians can draw information, particularly in the area of pharmacological treatment. However, emerging evidence points to the low risk of many psychotropic medications during pregnancy. Uncertainty must not prevent frank risk-benefit discussions from occurring between treating physicians and their pregnant patients. Psychiatrists can prepare themselves for management decisions by reviewing the current literature.

Diminished response to pleasant stimuli by depressed women.

This study examined the self-report and facial expressions of emotional response to pictorial stimuli and the incidental learning of pleasant and unpleasant words by depressed (n = 20) and nondepressed (n = 20) women. Depression was associated with reports of diminished emotional response and reduced frequency and intensity of facial expressions only to pleasant stimuli. The 2 groups did not differ in response to hedonically unpleasant stimuli, even those specifically relevant to the emotion of sadness. In a similar vein, depressed and nondepressed participants showed differences in incidental recall for only pleasant self-referential terms. There was no difference in recall of unpleasant words. These findings suggest the importance of hedonic deficits on psychological processes in clinical depression.

Prevention of recurrent postpartum depression: a randomized clinical trial.

BACKGROUND: Women who have suffered one episode of postpartum-onset major depression (PPMD) comprise a high-risk group for subsequent episodes. We conducted a double-blind, randomized clinical trial to test the efficacy of nortriptyline in the prevention of recurrent PPMD. METHOD: Nondepressed women who had at least one past episode of PPMD (Research Diagnostic Criteria) were recruited during pregnancy. Subjects were randomly assigned to nortriptyline or placebo. Treatment began immediately postpartum. Each subject was assessed for 20 sequential weeks with the Hamilton Rating Scale for Depression and Research Diagnostic Criteria for recurrence of major depression. RESULTS: No difference was found in the rate of recurrence in women treated with nortriptyline compared with those treated with placebo. Of 26 subjects who took nortriptyline preventively, 6 (0.23, 95% exact confidence interval [CI] = 0.09 to 0.44) suffered recurrences. Of 25 subjects who took placebo, 6 (0.24, 95% exact CI = 0.09 to 0.45) suffered recurrence (Fisher exact p = 1.00). CONCLUSION: Nortriptyline did not confer additional preventive efficacy beyond that of placebo. The rate of recurrence of PPMD (one fourth of women) was unacceptably high.

Serum fluvoxamine levels in breastfed infants.

BACKGROUND: Between 10% and 15% of new mothers will experience an episode of postpartum depression. Although antidepressants are effective agents for the treatment of postpartum depression, minimal data are available to support their safety in infants of breastfeeding mothers. METHOD: In this article, we present 2 cases of nursing mother-infant pairs in which the mother was treated with fluvoxamine and in which infant serum fluvoxamine levels were obtained. Both mothers began the fluvoxamine treatment postpartum, and serum levels were obtained from mothers and infants after a minimum of 7 days on a stable maternal dose. One level was obtained from the infant in case 1, and 2 levels were obtained from the infant in case 2. RESULTS: Each of the infant serum fluvoxamine levels obtained was too low to quantify (at a limit of detection of 2.5 ng/mL). Neither of the infants experienced adverse events related to the mother's treatment with fluvoxamine. Each of the infants is reportedly healthy 2 to 3 years after the exposure. CONCLUSION: While these results are encouraging, they are limited and cannot be generalized to all cases of infants exposed to fluvoxamine. Additional mother-infant serum fluvoxamine levels and infant behavioral observations will facilitate the risk-benefit decision-making process for women who choose to breast-feed while taking fluvoxamine.

Risk-benefit decision making for treatment of depression during pregnancy.

OBJECTIVE: The Committee on Research on Psychiatric Treatments of the American Psychiatric Association identified treatment of major depression during pregnancy as a priority area for improvement in clinical management. The goal of this article was to assist physicians in optimizing treatment plans for childbearing women. METHOD: The authors' work group developed a decision-making model designed to structure the information delivered to pregnant women in the context of the risk-benefit discussion. Perspectives of forensic and decision-making experts were incorporated. RESULTS: The model directs the psychiatrist to structure the problem through diagnostic formulation and identification of treatment options for depression. Reproductive toxicity in five domains (intrauterine fetal death, physical malformations, growth impairment, behavioral teratogenicity, and neonatal toxicity) is reviewed for the potential somatic treatments. The illness (depression) also is characterized by symptoms of somatic dysregulation that compromise health during pregnancy. The patient actively participates and provides her evaluation of the acceptability of the various treatments and outcomes. Her capacity to participate in this process provides evidence of competence to consent. Included in the decision-making process are the patient's significant others and obstetrical physician. The process is ongoing, with the need for incorporation of additional data as the pregnancy and treatment response progress. CONCLUSIONS: The conceptual model provides structure to a process that is frequently stressful for both patients and psychiatrists. By applying the model, clinicians will ensure that critical aspects of the risk-benefit discussion are included in their care of pregnant women.

Serum valproate levels in 6 breastfeeding mother-infant pairs.

BACKGROUND: Women with bipolar disorder are at high risk for recurrence of an affective episode in the postpartum period, and treatment with a mood stabilizer may be indicated. Few data are available to inform the risk-benefit decision regarding the use of valproate for women with bipolar disorder who elect to breast-feed. METHOD: Serum valproate levels were obtained from 6 breastfeeding mother-infant pairs. All mothers had a diagnosis of bipolar disorder (Research Diagnostic Criteria) and were taking divalproex sodium as prophylaxis for or treatment of a recurrent affective episode. None of the mothers received valproate during pregnancy. RESULTS: The mothers had serum valproate levels near or within the therapeutic range (39.4 to 79.0 microg/mL). Infant serum levels were low, ranging from 0.7 to 1.5 microg/mL (0.9%-2.3% of maternal serum levels). No adverse clinical effects were observed in the infants. CONCLUSION: Serum valproate levels were low in nurslings of mothers treated with valproate. These data can be used to inform clinical decisions regarding the use of valproate during breastfeeding.

Pharmacologic treatment of depression during pregnancy.

CONTEXT: Despite the frequency of depression in women of childbearing age, information to guide patients and physicians through a consideration of treatment during pregnancy is limited. OBJECTIVE: To identify risk factors associated with treatment of major depression during pregnancy to help physicians develop treatment plans that optimize clinical care. DATA SOURCES: Reports of prospective controlled trials in English were identified from MEDLINE and Health STAR using the search terms antidepressant during pregnancy and depression during pregnancy, by manually searching bibliographies of review articles, and through discussions with investigators for 1989-1999. STUDY SELECTION: We selected studies in which maternal and infant health outcomes associated with antidepressant exposure were compared with those of non-teratogen-exposed controls. Four studies published since 1993 were identified and included in the analysis. DATA EXTRACTION: We abstracted information about identification of subjects, comparison groups, pregnancy, and birth outcomes. We organized the data along 5 domains of reproductive toxicity: intrauterine fetal death, morphologic teratogenicity, growth impairment, behavioral teratogenicity, and neonatal toxicity. DATA SYNTHESIS: Data were available for tricyclic antidepressants (collectively), fluoxetine, and newer selective serotonin reuptake inhibitors (collectively). Exposure to these agents did not increase risk for intrauterine death or major birth defects. Decreased birth weights of infants exposed to fluoxetine in the third trimester were identified in 1 study. The development of children whose mothers took tricyclics or fluoxetine during gestation did not differ from that of controls. Direct drug effects and withdrawal syndromes occurred in some neonates whose mothers were treated with antidepressants near term. CONCLUSIONS: Although few in number, new information from prospective studies provides a welcome change from decision making based on nonprospective data. Monitoring and interventions for patients with identified risks (eg, poor weight gain) are recommended.

Obsessions and compulsions in women with postpartum depression.

OBJECTIVE: The quantity, content, and intensity of the obsessions and compulsions of women with postpartum onset major depressive disorder were compared with those of women with major depressive disorder with non-postpartum onset. METHOD: Sequential cases of women with postpartum onset major depression (N = 37) and major depression (N = 28) who presented to our Women's Mood Disorders program were included. Psychiatric examination using DSM-IV criteria and the Inventory to Diagnose Depression established the diagnosis of major depression. Obsessive thoughts and compulsions were reported on the Yale-Brown Obsessive Compulsive Scale and reviewed during the psychiatric examination. Comparisons between groups were performed with chi-square statistics, Fisher exact test and its extensions, and Mann-Whitney U test. RESULTS: Although more women with postpartum onset major depression (N = 21, 57%) than major depression (N = 10, 36%) reported obsessional thoughts, the difference between the groups was not significant (p = .13). However, for women who endorsed obsessions, those with postpartum onset had a higher median number (median = 7) than women without postpartum onset (median = 2, p = .00). Most of the difference in frequency of thoughts was owing to more women with postpartum onset major depression having aggressive thoughts (N = 20, 95%) than women with major depression (N = 6, 60%, Fisher exact p = .03). The most frequent content of the aggressive thoughts for women with postpartum onset major depression was causing harm to their newborns or infants. The presence or number of obsessional thoughts or compulsions was not related to severity of the depressive episode. CONCLUSION: Childbearing-aged women commonly experience obsessional thoughts or compulsions in the context of major depressive episodes. Women with postpartum onset major depression experience disturbing aggressive obsessional thoughts more frequently than women with non-postpartum major depression.

Serum levels of valproate and carbamazepine in breastfeeding mother-infant pairs.

Few data are available about the use of anti-convulsants during breastfeeding. In this article, three women with bipolar disorder who insisted upon breastfeeding their infants were studied. One mother was treated with carbamazepine (CBZ) and two were treated with valproate (VLP) monotherapy. Mother and infant serum levels were assessed when maternal steady-state was reached. The infant whose mother took CBZ developed a serum level that was 15% of the total maternal CBZ. Free CBZ was 20% of maternal values. The two infants whose mothers took VLP developed low serum levels (1.5 and 6.0% of maternal values). In the series, the serum levels of both CBZ and VLP were lower than previously reported values. However, information is limited and careful monitoring is recommended.

Serum sertraline and N-desmethylsertraline levels in breast-feeding mother-infant pairs.

OBJECTIVE: The authors' goal was to study the serum sertraline levels of breast-feeding mothers and their infants. METHOD: They obtained serum levels of sertraline and N-desmethylsertraline in nine mother-infant pairs. RESULTS: Sertraline levels were very low (less than 2 ng/ml) in seven of the nine infants and low (3 ng/ml) in one. N-Desmethylsertraline levels were also low (6 ng/ml or less) in seven of the nine infants. One infant had a high level of N-desmethylsertraline, and one infant had unusual serum sertraline and N-desmethylsertraline values (half of its mother's levels). All infants were thriving. CONCLUSIONS: Most breast-feeding infants whose mothers were taking sertraline had very low serum levels of both sertraline and N-desmethylsertraline, consistent with published reports. The authors discuss in detail the one infant with unusually high levels.
