Abstract

Androgenic Polycystic Ovary Syndrome (PCOS) creates physical/emotional burdens in 4-20% of premenopausal women living with PCOS (WLWP) including: few menstruations per year, subfertility, hirsutism/acne and low quality of life by validated PCOS Questionnaire (PCOSQ). Combined hormonal contraceptives (CHC), the current standard-of-care, improve PCOSQ only 16%; with stopping CHC, benefits disappear within 6-months. We hypothesize too-fast brain/luteinizing hormone (LH) pulses cause PCOS. Progesterone (P4) slows LH when testosterone (FreeT) is normal. Combining two approved medications, Cyclic P4 with anti-androgen, Spironolactone (Sp), will likely provide effective, durable benefits. WLWP lit-review suggested significant P4 7-14-day benefits. A 6-month prospective feasibility study of CyclicP4/Sp is necessary. Overall purpose: Perform a pilot study in 40 WLWP on Cyclic P4 (300 mg/bedtime, 14 days/month) plus Spironolactone (Sp, 200 mg/d). Feasibility: Assess longitudinal within-WLWP 6-month changes in: 1) PCOSQ; 2) FreeT, HbA1c, and LH; plus 3) WLWP's acceptance of CyclicP4/Sp. Methods: Single-centre, prospective, longitudinal single cohort study. Recruit ~7-8 WLWP/month over 4-6 months; 85% retention. Eligible WLWP have physician-diagnosed PCOS, are 1-month off CHC/metformin, ages 19-35 (avoiding adolescence/perimenopause), HbA1c <6.4% (no diabetes) and commit to non-hormonal contraception, if needed. Recruitment uses online, internet, strategic ads and tear-tab posters.…

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
