1 Male & Female HRT Risks, Successes, the Future? Teresa Bailey, PharmD, BCPS, BCACP, FCCP June 2015 Objectives Explain the association of testosterone therapy with mortality, myocardial infarction, and stroke in men with low testosterone levels. Discuss the potential benefits of hormone replacement therapy in women Discuss the pros and cons of dehydroepiandrosterone for peri- and postmenopausal women. Pathophysiology Menopause o Loss of ovarian function leading to a state of permanent amenorrhea o Ovaries no longer able to respond to pituitary stimulating hormones, so estrogen levels are low and production of FSH and LH increases dramatically. o Average age of onset-51.4 years o Onset unaffected by: race, socioeconomic status, alcohol consumption, age of menarche, or age of last pregnancy. Cigarette smoking may accelerate onset up to 2 years because of gametotoxic effects of cigarette smoke on steroid hormone metabolism by liver. o Premature menopause-loss of ovarian function before the age of 35 years due to ovarian surgery, endocrinologic, autoimmune disorders 2 Estrogen and Progestin Therapy Benefits and Risks of Estrogen and Progestin Therapy (Ann Intern Med 1992;117(12):10381041) Benefits Estrogen 1. Relieves genitourinary atrophy Thinning of hair of the mons and shrinkage of the labia minora Atrophy of vulva leads to pruritus and pain Vaginal pH 4.55 68 creating a favorable environment for bacterial colonization Loss of lubrication dyspareunia Recurrent episodes of urinary frequency and urgency with dysuria 2. Relieves vasomotor instability Occurs in 75%–85% of women. Occurs usually within 12–24 months after the last menstrual period. Increased skin temperature, nausea, dizziness, headache, palpitations, diaphoresis, night sweats. 3. Osteoporosis-Reduction of hip fractures by 25%. Reduction of vertebral fractures by 50%. Estrogen reduces rate of resorption but does not restore bone loss. Progestin 1. Decrease risk of estrogen-induced irregular bleeding, endometrial hyperplasia, and carcinoma 2. Protection against breast carcinoma 3. Enhancement of estrogen prophylaxis of osteoporosis 4. Lowers LDL cholesterol by 11% and increases HDL cholesterol by 10%. However, was not shown to lower coronary heart disease based on HERS trial. 5. Increase in life expectancy 6. Insomnia and fatigue 7. Mood changes 8. Sexual function Risks Estrogen 1. Endometrial cancer by unopposed estrogen. Duration of estrogen use dependent; eightfold for 10–20 years of use. Recommended not to use in women with a history of endometrial cancer. 2. Breast cancer with unopposed estrogenuncertain. May increase slightly (25%) among women who take estrogen for 1020 years. Recommended not to use in women with a history of breast cancer. 3. Increased risk of cardiovascular outcomes. (See WHI trial). 4. Adverse effects: bloating, headache, breast tenderness (5–10%) 5. Unpredictable uterine bleeding with unopposed estrogen (35–40%) Progestin 1. Adverse effects: bloating, weight gain, irritability, depression. (Dose related) 2. Unpredictable endometrial bleeding with continuous estrogen/progestin during first 8–12 months (30–50%) 3 Contraindications of HRT • • • • • • • • • Undiagnosed abnormal genital bleeding Known, suspected, or history of breast cancer Known or suspected estrogen-dependent neoplasia Active DVT, PE, or a history of these conditions Active arterial thromboembolic disease (stroke and MI), or a history of these conditions Known anaphylactic reaction or angioedema to estrogens/progestins Known liver dysfunction or disease Known protein C, protein S, or antithrombin deficiency, or other known thrombophilic disorders Known or suspected pregnancy Efficacy on Coronary Artery Disease (JAMA 1998;280:605-613) WHI Trial: Efficacy on Coronary Artery Disease (NIH News Release NHLBI Stops Trial of Estrogen Plus Progestin Due to Increased Breast Cancer Risk, Lack of Overall Benefit. www.nhlbi.nih.gov/new/press/02-07-09.htm) Objective: HRT alter risk for coronary heart disease in postmenopausal women with established coronary disease Methods o R, DB, PC, 20 US center.
