Transdermal estradiol for postpartum depression: results from a pilot randomized, double-blind, placebo-controlled study.

ABSTRACT: Postpartum depression (PPD) is a common complication following delivery, though evidence-based treatment options are limited. This study explores the feasibility and efficacy of outpatient PPD treatment with transdermal estradiol (TE). In a pilot, double-blind, placebo-controlled trial, women with PPD were randomized to receive transdermal 17β-estradiol (100 mcg/day) or placebo patch. Over 6 weeks, women completed weekly ratings on the Beck Depression Inventory (BDI), Edinburgh Postnatal Depression Scale (EPDS), and Hamilton Depression Scale (HAM-D). Primary outcome measures were treatment response (> 50% decrease from baseline BDI) and remission (BDI < 10) at 6 weeks, and secondary outcome measures included severity on all scales at weeks 3 and 6. Of 12 recruited women, 6 received TE and 6 received placebo. By week 6, 5 women receiving TE responded to treatment and 4 showed symptom remission, compared to 2 responders and 1 remitter in the placebo group. This difference was not significant (p = 0.24). In a mixed-model of BDI ratings, TE was associated with a 9.2 point decrease at 3 weeks (95%CI - 19.5 to + 1.0, p = 0.074) and a 10.5 point decrease at 6 weeks (95%CI - 21.0-0.0, p = 0.049) compared to placebo, though these differences did not survive multiple comparisons correction. Analogous effects were found for HAM-D but not EPDS scores. Interestingly, no significant difference in plasma estradiol levels existed between groups. We were unable to demonstrate a significant therapeutic benefit of TE compared with placebo in PPD. Although limited by under-recruitment and loss to follow-up, our results suggest TE is a feasible option for outpatient PPD management, with preliminary evidence (based on secondary outcomes) for efficacy. Therapeutic effects may be seen as early as 3 weeks and may not directly depend on peripheral measures of estradiol.

Project description:BackgroundDietary recommendations for selenium differ between countries, mainly because of uncertainties over the definition of optimal selenium status.ObjectiveThe objective was to examine the dose-response relations for different forms of selenium.DesignA randomized, double-blind, placebo-controlled dietary intervention was carried out in 119 healthy men and women aged 50-64 y living in the United Kingdom. Daily placebo or selenium-enriched yeast tablets containing 50, 100, or 200 microg Se ( approximately 60% selenomethionine), selenium-enriched onion meals ( approximately 66% gamma-glutamyl-methylselenocysteine, providing the equivalent of 50 microg Se/d), or unenriched onion meals were consumed for 12 wk. Changes in platelet glutathione peroxidase activity and in plasma selenium and selenoprotein P concentrations were measured.ResultsThe mean baseline plasma selenium concentration for all subjects was 95.7 +/- 11.5 ng/mL, which increased significantly by 10 wk to steady state concentrations of 118.3 +/- 13.1, 152.0 +/- 24.3, and 177.4 +/- 26.3 ng/mL in those who consumed 50, 100, or 200 microg Se-yeast/d, respectively. Platelet glutathione peroxidase activity did not change significantly in response to either dose or form of selenium. Selenoprotein P increased significantly in all selenium intervention groups from an overall baseline mean of 4.99 +/- 0.80 microg/mL to 6.17 +/- 0.85, 6.73 +/- 1.01, 6.59 +/- 0.64, and 5.72 +/- 0.75 microg/mL in those who consumed 50, 100, or 200 microg Se-yeast/d and 50 microg Se-enriched onions/d, respectively.ConclusionsPlasma selenoprotein P is a useful biomarker of status in populations with relatively low selenium intakes because it responds to different dietary forms of selenium. To optimize the plasma selenoprotein P concentration in this study, 50 microg Se/d was required in addition to the habitual intake of approximately 55 microg/d. In the context of established relations between plasma selenium and risk of cancer and mortality, and recognizing the important functions of selenoprotein P, these results provide important evidence for deriving estimated average requirements for selenium in adults. This trial was registered at clinicaltrials.gov as NCT00279812.
