研究概览
简要总结
This study that aims to evaluate the psychophysiology of premenstrual mood disorders (PMDs) at baseline and after treatment with sertraline. Participants will include women with PMDs and healthy female controls. Participation involves a baseline visit to determine eligibility and three study visits that include questionnaires and stress reactivity assessment via an acoustic startle paradigm. Female participants with PMDs will receive sertraline during the premenstrual phase.
详细描述
Among women with premenstrual mood dysphoric disorder (PMDD), baseline arousal is heightened during the luteal phase of the menstrual cycle compared to the follicular phase, as measured by acoustic startle response (ASR). Healthy female controls do not show cyclic changes in this measure of physiologic arousal. It has been suggested that such heightened physiologic arousal during the luteal phase may be due to differences in neurosteroid modulation of Gamma-aminobutyric acid (GABA)-A receptor function. Research indicates that women with premenstrual mood disorders (PMDs) may have sub-optimal sensitivity to the progesterone metabolite allopregnanolone (ALLO), a GABA-A receptor modulator. In animal models, intracerebroventricular injection of corticotrophin releasing factor (CRF) increases amplitude of the acoustic startle response, while ALLO administration attenuates this CRF-enhanced startle. The primary aim of this study is to examine differences in ASR by menstrual cycle phase (follicular, luteal) and group (control, PMDD). Secondary aim is to examine the impact of luteal phase treatment with a selective serotonin reuptake inhibitor (SSRI) on psychophysiology in women with PMDs. An exploratory aim is to examine immune function among these women.

研究组 & 干预措施
Sertraline
To determine the impact of short term luteal phase treatment with Sertraline 50mg tablets (PMDD group only) on acoustic startle response across the menstrual cycle. Sertraline 50 mg tablets are administered daily from ovulation until menses onset.
干预措施: Sertraline (Drug)
结局指标
主要结局
Acoustic Startle Response (ASR) Magnitude Based on Menstrual Cycle Phase
时间窗: Month 1 (Follicular), Month 2 (Luteal)
Acoustic startle response (ASR) is measured during the follicular and luteal phase of the menstrual cycle in controls and those with PMDD. Magnitude of ASR is measured using the eyeblink reflex, by recording activity from the orbicularis oculi muscle. Recording is performed via two surface disk electrodes (Ag-AgCl) applied underneath the left eye; one in line with the pupil and one 1-2 cm lateral to the first one. For the primary outcome of baseline ASR magnitude over the menstrual cycle, peak amplitude of the blink reflex was determined in the 20-120-ms time frame following stimulus onset relative to baseline (baseline is the average baseline electromyography (EMG) level for the 50 ms immediately preceding auditory stimulus onset). ASR is measured in microvolts, and raw ASR results are standardized to t-scores. Higher ASR t-score indicates greater contraction of the the orbicularis oculi muscle. A t-score of 50 indicates the population mean with a standard deviation of 10.
Impact of Sertraline on ASR Magnitude
时间窗: Month 2 (Luteal), Month 3 (Luteal)
This outcome examines the impact of luteal phase treatment with a selective serotonin reuptake inhibitor (SSRI) (PMDD group only) on acoustic startle response (ASR). ASR is measured using the eyeblink reflex, measured by recording activity from the orbicularis oculi muscle. Recording is performed via two surface disk electrodes (Ag-AgCl) applied underneath the left eye; one in line with the pupil and one 1-2 cm lateral to the first one. Peak amplitude of the blink reflex is determined in the 20-120-ms time frame following stimulus onset. PMDD participants complete test day 3 (Luteal Month 3) while on sertraline and their ASR magnitude will be compared to their previous luteal test day (Luteal Month 2). ASR is measured in microvolts, and raw ASR results are standardized to t-scores. Higher ASR t-score indicates greater contraction of the the orbicularis oculi muscle. A t-score of 50 indicates the population mean with a standard deviation of 10.
