Pooled analysis of antidepressant levels in lactating mothers, breast milk, and nursing infants.

OBJECTIVE: The available data on antidepressant levels in nursing infants were analyzed in order to calculate average infant drug levels and determine what factors influence plasma drug levels in breast-feeding infants of mothers treated with antidepressants. METHOD: Electronic searches of MEDLINE, PreMEDLINE, Current Contents, Biological Abstracts, and PsycINFO from 1966 through July 2002 followed by bibliographic searches identified 67 relevant studies (two unpublished). By consensus the authors identified 57 studies of maternal plasma, breast milk, and/or infant plasma antidepressant levels from nursing mother-infant pairs, measured by liquid chromatography. RESULTS: Infants with recent prenatal exposure and symptomatic infants included in case reports were analyzed separately. Infant plasma levels were standardized against the average maternal level for each drug. The average infant-maternal plasma ratio was calculated for each drug, and correlations of infant plasma level to maternal dose, maternal plasma level, and breast milk level were calculated. Nortriptyline, paroxetine, and sertraline usually produce undetectable infant levels. Of drugs currently used, fluoxetine produces the highest proportion (22%) of infant levels that are elevated above 10% of the average maternal level. Based on smaller numbers, the data on citalopram indicate that it produces elevated levels in 17% of infants. The milk-to-plasma ratios for 11 antidepressants had a statistically significant negative association with the percentage of the drug bound to protein. CONCLUSIONS: Nortriptyline, paroxetine, and sertraline may be preferred choices in breast-feeding women. Minimizing the maternal dose may be helpful with citalopram. Current data do not support monitoring breast milk levels in individual patients. Future researchers should report maternal, breast milk, and infant antidepressant levels along with other appropriate variables.

Prevention of postpartum depression: a pilot randomized clinical trial.

OBJECTIVE: The authors attempted to reduce the rate of postpartum depression in high-risk women and to increase the time to recurrence. METHOD: Nondepressed pregnant women with at least one past episode of postpartum major depression were recruited into a randomized clinical trial. Mothers were assigned randomly to a 17-week trial of sertraline or placebo immediately after birth and assessed for 20 sequential weeks with the Hamilton Rating Scale for Depression. RESULTS: Of 14 subjects who took sertraline, one (7%) suffered a recurrence. Of eight subjects who were assigned to placebo, four (50%) suffered recurrences. This difference was significant. The time to recurrence was significantly longer in the sertraline-treated women than in the placebo-treated women. CONCLUSIONS: Sertraline conferred preventive efficacy for postpartum-onset major depression beyond that of placebo.

Randomized clinical trial of bright light therapy for antepartum depression: preliminary findings.

BACKGROUND: Bright light therapy was shown to be a promising treatment for depression during pregnancy in a recent open-label study. In an extension of this work, we report findings from a double-blind placebo-controlled pilot study. METHOD: Ten pregnant women with DSM-IV major depressive disorder were randomly assigned from April 2000 to January 2002 to a 5-week clinical trial with either a 7000 lux (active) or 500 lux (placebo) light box. At the end of the randomized controlled trial, subjects had the option of continuing in a 5-week extension phase. The Structured Interview Guide for the Hamilton Depression Scale-Seasonal Affective Disorder Version was administered to assess changes in clinical status. Salivary melatonin was used to index circadian rhythm phase for comparison with antidepressant results. RESULTS: Although there was a small mean group advantage of active treatment throughout the randomized controlled trial, it was not statistically significant. However, in the longer 10-week trial, the presence of active versus placebo light produced a clear treatment effect (p =.001) with an effect size (0.43) similar to that seen in antidepressant drug trials. Successful treatment with bright light was associated with phase advances of the melatonin rhythm. CONCLUSION: These findings provide additional evidence for an active effect of bright light therapy for antepartum depression and underscore the need for an expanded randomized clinical trial.

Postpartum depression recurrence versus discontinuation syndrome: observations from a randomized controlled trial.

OBJECTIVE: To differentiate characteristics of a discontinuation syndrome from a recurrence of major depressive disorder in the context of a randomized trial. METHOD: We performed a randomized clinical trial to compare the efficacy of sertraline versus placebo for the prevention of recurrent postpartum DSM-IV major depressive disorder. Women whose depression did not recur in the initial 17-week active treatment trial were followed through the taper phase (weeks 18-20). At week 17, 3 women assigned to placebo and 8 assigned to sertraline remained in the trial. Nine symptoms that characterize discontinuation syndrome were extracted from the 25-item Asberg Rating Scale for Side Effects (ASE) and assessed weekly during the taper phase. The 21-item Hamilton Rating Scale for Depression was used to evaluate depressive symptoms. RESULTS: In the taper phase, there were no significant differences between the sertraline- and placebo-treated women on the sum of the ASE-derived symptoms. Both groups had low levels of symptoms on the ASE during the weeks of taper. None of the 3 women assigned to placebo and 2 of the 8 women assigned to sertraline suffered a depressive recurrence within 6 weeks of the end of the study. CONCLUSIONS: A gradual taper of sertraline (75 mg) over 3 weeks did not lead to discontinuation syndrome; however, the systematic dissection of symptoms resulted in our conclusion that the duration of preventive therapy should be extended to 26 weeks (about 6 months) in subsequent randomized trials, consistent with the treatment guidelines for a single episode of depression.

Bridging the gap: recruitment of African-American women into mental health research studies.

OBJECTIVE: To develop a strategy for recruiting African-American women into a research study for pregnant women. METHODS: With few exceptions, NIH-funded investigators must include women and minorities in clinical research. The authors used the recommendations provided in the Outreach Notebook for the NIH Guidelines on Inclusion of Women and Minorities as Subjects in Clinical Research as a guide to help them reach out to African-American women in the community. RESULTS AND CONCLUSIONS: The outreach experience led to a conference for African-American women about mental health. On the basis of this experience, the authors formulated a five-pronged approach for recruitment of African-American women into their study. The NIH guidelines were useful for this purpose.

Verapamil treatment for women with bipolar disorder.

BACKGROUND: Additional pharmacological treatments are needed for patients with bipolar disorder. We describe our experience with verapamil in an inclusive, sequential series of outpatient women (some pregnant) with bipolar disorder. METHODS: All women who were prescribed verapamil for bipolar disorder (n = 37) were included. We used the criterion of 50% reduction in scores on the Mania Rating Scale or the Hamilton Rating Scale for Depression to define response for women who were treated for an acute episode of bipolar hypomania/mania or depression, respectively. For euthymic women who chose verapamil maintenance treatment, we evaluated whether they met criteria for a recurrent episode during therapy. RESULTS: Treatment for acute episodes was initiated in 28 women. Of women with depression and mania, 39% and 100% responded, respectively. Seven of the nine patients (77%) with mixed states responded: all seven improved to response criterion on the mania scale, and two responded on the depression scales as well. Six of eight patients who received continuation therapy remained well. CONCLUSIONS: These data provide evidence that verapamil is effective for mania. The response rate for mania compares favorably to that for other mood stabilizers. After decades of case reports and underpowered clinical trials, we must definitively study verapamil for efficacy and gender specificity in bipolar disorder.

An open trial of morning light therapy for treatment of antepartum depression.

OBJECTIVE: About 5% of pregnant women meet criteria for major depression. No pharmacotherapy is specifically approved for antepartum depression; novel treatment approaches may be welcome. The authors explored the use of morning bright light therapy for antepartum depression. METHOD: An open trial of bright light therapy in an A-B-A design was conducted for 3-5 weeks in 16 pregnant patients with major depression. The Hamilton Depression Rating Scale, Seasonal Affective Disorders Version, was administered to assess changes in mood. A follow-up questionnaire was used to assess outcome after delivery. RESULTS: After 3 weeks of treatment, mean depression ratings improved by 49%. Benefits were seen through 5 weeks of treatment. There was no evidence of adverse effects of light therapy on pregnancy. CONCLUSIONS: These data provide evidence that morning light therapy has an antidepressant effect during pregnancy. A randomized controlled trial is warranted to test this alternative to medication.

Serum bupropion levels in 2 breastfeeding mother-infant pairs.

BACKGROUND: These are the first reported data on bupropion and hydroxybupropion levels in infants whose treated mothers were breastfeeding. The information will assist physicians and parents in the risk-benefit decision-making process for bupropion treatment during breastfeeding. METHOD: Serum samples were obtained by venipuncture from 2 mother-infant pairs. The serum was assayed for levels of bupropion and its most active metabolite, hydroxybupropion. RESULTS: Neither infant had quantifiable serum levels of bupropion or its metabolite at steady state. Neither infant had medical problems during the time of maternal therapy. CONCLUSION: We recommend obtaining and publishing additional serum level findings for breastfeeding mother-infant pairs since data for bupropion are favorable but limited.

Collaborative management of women with bipolar disorder during pregnancy and postpartum: pharmacologic considerations.

Bipolar disorder is a chronic condition characterized by periods of mania, depression, or mixed states (co-occurring mania and depression). The postpartum period is associated with a high risk for symptom relapse or intensification, which can be reduced with the use of medications. Abrupt discontinuation of these medications increases the probability of relapse, which is associated with high-risk behaviors, significant family dysfunction, and suicide. Drugs used to treat patients with bipolar disorder vary in teratogenic potential. Although first trimester lithium use is associated with Ebstein's anomaly, the risk was overestimated in the past. Valproate and its derivatives and carbamazepine are human teratogens. Lamotrigine does not negatively impact major reproductive outcomes, but the data are limited. Typical antipsychotic medications are relatively well studied and the data do not identify major morphologic teratogenicity. There are fewer studies of newer atypical antipsychotic medications, and registries have been developed to collect prospective data. Clinical management of bipolar disorder during pregnancy, postpartum, and lactation requires a careful balancing of maternal and fetal risks and benefits. Communication and careful comanagement between the obstetric and psychiatric team is essential when treating women with bipolar disorder during the reproductive years.

Successful recruitment strategies for women in postpartum mental health trials.

Recruiting women into research protocols allows investigators to examine the efficacies of treatments and to study other outcomes among women with mental illnesses. However, achieving recruitment goals has been difficult for researchers. The objective of this study was to examine the success rates of different strategies for recruiting women into clinical trials for the prevention and treatment of postpartum major depression. This is a descriptive study designed to examine which recruitment efforts, over a 4-year period, yielded women who participated in the studies. It was conducted in an outpatient clinic affiliated with a major urban teaching hospital where women of childbearing age sought treatment for affective disorders. All women (n=589) who called about our research studies were systematically screened. The women were either pregnant or in the postpartum period. Our results show that in both studies, obstetricians and other healthcare professionals referred a large number of women. These referrals yielded relatively high rates of participation. However, other methods were differentially successful for the two studies: media appearances and advertising resulted in almost 50% of the screening calls for the prevention study, whereas mass mailings and other promotional materials were more effective for the treatment study. Those materials contributed 44% of screening calls for the treatment study. Our conclusions were that women were most likely to enter the research studies when referred by an obstetrician or other professional.

The impact of postpartum depression on mothering.

As a rule, mothers are the primary caregivers of infants regardless of employment or marital status. Thus, any factors that impact mothering affect the infant and have public health significance. National attention is now focused on postpartum depression, a major variable affecting mothering. The impact of postpartum depression on the various components of the maternal role is described. Recommendations for health care practice include screening for depression across the first postpartum year and developing a strong network for mental health referrals.
