Goals of hormone replacement therapy (ex. menopause)

~ reduce estrogen withdrawal symptoms (hot flashes, lack of sleep, cognitive symptoms, vaginal discomfort)
~ reduce chances of osteoporosis
~ treat urogenital atrophy (common post menopause - ex. prolapse, stress incontinence, etc)


What is premature ovarian insufficiency = failure? Should it be treated like menopause?

menopause = ave age 51
POF = iatrogenic (surgery, chemo, radiation; infection; autoimmune)

POF is NOT menopause - lower risk of breast cancer but earlier onset CHF and osteoporosis. Hormone RT is recommended at least until at least normal age of onset of menopause (NA menopause society), but findings of menopause studies cannot be generalized here


What are biggest health risks of menopause?

CV disease is leading cause of death post-menopause


What are risks associated with combined hormone therapy? (estrogen + progesterone)

- breast cancer (combined but not with estrogen, think opposite endometrial cancers)
IMPORTANT: breast cancer risk increases after 5 years of hormone therapy, no changes if 1-4 years of therapy only; risk does not increase with estrogen alone. also remember that biggest predictor of breast cancer is family history, everything else pails in comparison significantly
- cardiovascular disease
- dementia (some studies)
- stroke (transdermal estrogen alone does not increase risk, but oral estrogen does!)
- DVT (transdermal estrogen does not increase risk, but oral estrogen does)
- smaller studies showed that estrogen does not directly increase CV disease - if taken pre menopause or during menopause - arterial health good, but if taken post menopause, say > 55-65 years old, it can increase mural thrombi - timing (KEEPS study)
- PE
- very slight 1:1000 incr. in ovarian cancer
primarily based on women's health initiative study


what are benefits of combined hormone therapy?

- reduction in osteoporosis
- reduction in endometrial cancers
- reduction in colon cancers
- reduction in estrogen withdrawal symptoms (vasomotor = think hot flashes, etc)


What are specific risks of combined therapy?

biggest is breast cancer if used beyond 5 years, but benefit of colon cancer


Absolute counterindications to hormone therapy?

think similar to birth control:
~ Live Dreamily (DVT) in BC, Canada (bleeds, CV, Cancer) = think lots of retirees post menopausal
~ ACUTE Liver Disease (makes worse)
~ undiagnosed vaginal BLEEDS
~ vascular thrombosis (DVT)
~ uterine and breast cancer


Side effects of hormone therapy?

abnormal uterine bleeding
breast tenderness
edema, heartburn, nausea
mood changes (progesterone)


Main principles of pharmacotherapy?
high/low doses, short/long duration

doses low, duration short <5 years b/c of breast cancer risk


would you give progesterone to women with no uterus?

no point - mainly used to prevent endometrial hypertrophy, if no endometrium, has no added benefit and increased risk of breast cancer
