Cyclic Progesterone Therapy in Androgenic Polycystic Ovary Syndrome (PCOS)—A 6-Month Pilot Study of a Single Woman’s Experience Changes

Background and Objectives: Women with androgenic Polycystic Ovary Syndrome (PCOS) have increased endometrial cancer risk that cyclic progesterone will prevent; it may also reverse PCOS’s neuroendocrine origins. This pilot study’s purpose was to document 6-month experience changes in a woman with PCOS taking cyclic progesterone therapy because she was intolerant of combined hormonal contraceptive therapy, the current PCOS standard of care. A 31-year-old normal-weight woman with PCOS had heavy flow, irregular cycles, and was combined hormonal contraceptives-intolerant. She was prescribed cyclic oral micronized progesterone (OMP) (300 mg/h.s. cycle days 14–27). She kept Menstrual Cycle Diary© (Diary) records, starting with the 1st treatment cycle for six cycles; she was on no other therapy. Statistical analysis a priori hypothesized progesterone decreases high estradiol (E2) experiences (flow, cervical mucus, fluid retention, front-of-the-breast tenderness and anxiety); analysis focused on these. Our objectives: (1) changes from cycles 1 to 6 in E2-related experiences; and (2) follicular phase E2-related changes from cycle 1 (no therapy) to cycles 3 and 6. Materials and Methods: Data from consecutive Diaries were entered into an SPSS database and analyzed by Wilcoxon Signed Rank Test (Objective #1) within-person whole cycle ordinal data, and (Objective #2 follicular phase) repeated measures ANOVA. Results: Cyclic OMP was associated with regular, shorter cycles (±SD) (28.2 ± 0.8 days). Comparison of cycles 1–6 showed decreased fluid retention (p = 0.001), breast tenderness (p = 0.002), and cervical mucus (p = 0.048); there were no changes in flow or anxiety. Fluid retention in the follicular phase also significantly decreased over time (F (1.2, 14.7) = 6.7, p = 0.017). Conclusions: Pilot daily Diary data suggest women with PCOS have improved everyday experiences on cyclic progesterone therapy. Larger prospective studies with more objective outcomes and randomized controlled trials of this innovative PCOS therapy are needed.Medicine, Faculty ofNon UBCEndocrinology, Division ofMedicine, Department ofPopulation and Public Health (SPPH), School ofReviewedFacultyResearche

Adult Premenopausal Bone Health Related to Reproductive Characteristics—Population-Based Data from the Canadian Multicentre Osteoporosis Study (CaMos)

Amenorrhea is important for women’s bone health. However, few have reported reproductive, anthropometric (body mass index [BMI], height) and bone health (areal bone mineral density [BMD], prevalent fractures) in a population-based study. The purposes of this cross-sectional study of women in the randomly-selected Canadian Multicentre Osteoporosis Study (CaMos) population were: (1) to describe reproductive, demographic, anthropometric and lifestyle variables; and (2) in menstruating women, to relate reproductive and other variables to BMD at the lumbar spine (L1-4, LS), femoral neck (FN) and total hip (TH) sites and to prevalent fragility fractures. This study describes the reproductive characteristics of 1532 women aged 30–60 years. BMD relationships with reproductive and other variables were described in the 499 menstruating women. Mean menarche age was 12.8 years, 96% of women were parous and 95% had used combined hormonal contraceptives (CHC). Infertility was reported by 9%, androgen excess by 13%, amenorrhea by 8% and nulliparity by 4%. LS BMD was negatively associated with amenorrhea and androgen excess and positively related to current BMI and height. A later age at menarche negatively related to FN BMD. BMI and height were strongly related to BMD at all sites. Prevalent fragility fractures were significantly associated with quartiles of both LS and TH BMD.Medicine, Faculty ofOther UBCNon UBCEndocrinology, Division ofMedicine, Department ofPopulation and Public Health (SPPH), School ofReviewedFacult

Women’s Mid-Life Night Sweats and 2-Year Bone Mineral Density Changes: A Prospective, Observational Population-Based Investigation from the Canadian Multicentre Osteoporosis Study (CaMos)

Women’s hot flushes and night sweats, collectively called vasomotor symptoms (VMS), are maximal (79%) in late perimenopause. The evidence describing whether VMS are associated with loss of areal bone mineral density (BMD) is mixed. We examined baseline and 2-year data for 1570 randomly selected women aged 43–63 in the Canadian Multicentre Osteoporosis Study (CaMos), a prospective Canada-wide study; we used linear regression to assess the relationship of night sweats (VMSn) with BMD and its changes. Clinically important VMSn occurred for 12.2%. Women with VMSn were slightly younger (54.5 vs. 55.3 years, p = 0.02) and less likely to use sex steroid therapies (39.8% vs. 51.4%, p < 0.05). BMD at the lumbar spine (L1-4), femoral neck (FN) and total hip (TH) were similar between those with/without VMSn. In adjusted models, we did not find a significant association between VMSn and 2-year change in L1-4, FN and TH BMD. Age, reproductive status, weight, sex steroid therapy and smoking status were associated with 2-year change in BMD. Incident fractures over 2 years also did not differ by VMSn. Our analyses were restricted to VMSn and may not truly capture the relationship between VMS and BMD. Additional research involving VMS, bone loss and fracture incidence is needed.Medicine, Faculty ofOther UBCNon UBCEndocrinology, Division ofMedicine, Department ofPopulation and Public Health (SPPH), School ofReviewedFacult

Does Molimina Indicate Ovulation? Prospective Data in a Hormonally Documented Single-Cycle in Spontaneously Menstruating Women

Approximately 33% of normal-length (21–35 days) cycles have subclinical ovulatory disturbances and lack sufficient progesterone, although their normal length ensures enough estrogen. Subclinical ovulatory disturbances are related to significant premenopausal spine bone loss (−0.86%/year). Molimina, non-distressing premenstrual experiences, may detect ovulation within normal-length cycles. This prospective study assessed the relationship between molimina and ovulation. After 1-cycle of daily diary and first morning urine collections, women answered the Molimina Question (MQ): “Can you tell by the way you feel that your period is coming?” and were invited to share (a) predictive premenstrual experience(s). A 3-fold increase in follicular-luteal pregnanediol levels confirmed ovulation. In 610 spontaneously menstruating women (not on hormonal contraception, mean age 31.5 ± 5.3, menarche age 12.7 ± 1.5, cycle length [CL] 29 days, MQ positive in 89%), reported premenstrual experiences which included negative moods (62%), cramps (48%), bloating (39%), and front (26%) or axillary (25%) breast tenderness. Of 432 women with pregnanediol-documented cycles, 398 (92%) were ovulatory (CL: 29 ± 5) and 34 (8%) had ovulatory disturbances (CL: 32 ± 14). Women with/without ovulatory cycles were similar in parity, body mass index, smoking, dietary restraint and the MQ; ovulatory-disturbed cycles were longer. Molimina did not confirm ovulation. A non-invasive, inexpensive ovulation indicator is needed to prevent osteoporosis.Medicine, Faculty ofOther UBCNon UBCEndocrinology, Division ofMedicine, Department ofNeurology, Division ofObstetrics and Gynaecology, Department ofPopulation and Public Health (SPPH), School ofReviewedFacult

Phase II 6-month Cyclic Progesterone/Spironolactone pilot Therapy Trial in Polycystic Ovary Syndrome : pre-post, single-arm feasibility study

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. Measures at 0 and 6 months: as above plus K+ (safety assessment). Menstrual Cycle Diary monitoring (flow, adherence), 2 visits, monthly telephone/emails for support and assessment of any adverse effects. Statistical analysis: changes by paired T-test. Summary: A feasibility 6-month study of CyclicP4/Sp will facilitate a CIHR-funded RCT of CHC versus this innovative and likely beneficial treatment for WLWP.Medicine, Faculty ofEndocrinology, Division ofMedicine, Department ofPopulation and Public Health (SPPH), School ofUnreviewedFacultyResearche

Oral Micronized Progesterone for Perimenopausal Vasomotor Symptoms Study

This is a randomized, double-masked, placebo-controlled trial of oral micronized progesterone (300 mg at bedtime daily) for hot flushes and night sweats (collectively vasomotor symptoms, VMS) in women stratified to be in Early or Late Perimenopause. We have recently completed a similar trial showing that oral micronized progesterone provides effective therapy for healthy postmenopausal women with VMS. Currently there is no effective, evidence based treatment for perimenopausal VMS.
