Menopause

Paul Beck, MD, FACOG, FACS

what is menopause
What is Menopause
  • Loss of ovarian activity – loss of menses
  • Loss of estrogen-significant impact
  • Life span in menopause – 1/3 to ½
menopause demographics

42 million women over age 50

52 million by 2010

8.8 million women age 50 to 54

Average age at menopause 51.4 years

(range – 45 to 55 years)

MenopauseDemographics
primary symptoms of menopause
Primary Symptoms of Menopause
  • Cycle changes
  • Oligoamenorrhea – amenorrhea
  • Vasomotor
  • Vaginal dryness
secondary symptoms of menopause
Secondary Symptoms of Menopause
  • Urinary – stress/urge incontinence
  • Frequency – burning ( cystitis)
  • Psychophysiologic changes
  • Musculoskeletal pains
  • Decrease concentration
  • Decreased libido
actions of estrogen
Actions of Estrogen
  • Development of ovaries, tubes, uterus and vagina
  • Secondary sexual characteristics
  • HPO axis interaction
  • Proliferative changes in the endometrium
  • Increases fat deposition and vascular profusion of skin
actions of progesterone
Actions of Progesterone

Specific

  • Interacts with hypothalmus and pituitary to regulate menstrual cycle
  • Produces secretory changes in the endometrium
  • Increases viscosity of cervical mucus
  • Prepares breast for lactation during pregnancy
consequences and impact of estrogen loss
Consequences and Impact of Estrogen Loss
  • Hot flashes
  • Sleep disturbance
  • Urogenital Atrophy
  • Osteoporosis
  • Skin Dryness
  • Aging
managment
Managment
  • Hormone therapy
  • Alternative therapy
  • Grin and bear it
estrogen progesterone therapy potential risks and concerns
Estrogen/Progesterone TherapyPotential Risks and Concerns
  • Women’s health initiative study
  • Breast cancer
  • Cardio vascular disease
  • Venous thrombosis
  • Endometrial cancer
  • Compliance/therapy
whi objective
WHI Objective
  • Assess benefits and risks of the most commonly used E/P combination in the US
  • 16,608 women randomized
  • 8, 506 – E+P (.625 CEE + 2.5 MP)
  • 8, 102 – placebo
  • Planned duration 8.5 years
  • Post menopausal women age 50 – 79 years
whi main outcome measures
WHI Main Outcome Measures
  • Primary outcome

coronary heart disease (CHD): non-fatal

myocardial infarction and CHD death

  • Primary adverse outcome

invasive breast cancer

  • Secondary outcomes

stoke

pulmonary embolism

endometrial cancer

cholorectal cancer

hip fracture

death due to other causes

whi continued
WHI Continued
  • No substantive difference between groups at baseline
  • Mean age 63.2 for E+P group
  • Mean age 63.3 for placebo group
  • 2/3 between 60 and 79 years
whi status
WHI Status
  • E+P study stopped early – 531 2002, mean 5.2 years
  • Reason – increase in invasive breast cancer exceeded the safety boundary for harm
  • Evidence for some increase in CHD, stroke and pulmonary embolism
  • Outweighed evidence fracture decrease
  • Unopposed estrogen study continued
whi time trends
WHI Time Trends
  • CHD began to develop soon after randomization (first year)
  • Breast Cancer – comparable through first four years then curve for estrogen began to rise more rapidly then placebo
  • 5.2 years sharper increase- more pronounced
women s heath initiative primary conclusion
Women’s Heath Initiative Primary Conclusion

“The risk-benefit profile found in this trial is not consistent with the requirements for a viable intervention for primary prevention of chronic diseases, and the results indicate that this regiment should not be initiated or continued for primary prevention of CHD.”

Writing Group for the Women’s Health Initiative Investigators

JAMA 2002;288:321-333

whi implications limitations
WHI Implications/Limitations
  • Absolute risks –small-previously described
  • E/PT for treatment of menopausal symptoms not evaluated
  • Only one drug used not comparable for other E/PTs
alternative measures vasomotor symptoms
Alternative MeasuresVasomotor Symptoms
  • Progesterone/oral and transdermal works/adverse affect on lipid profile
  • Micronized natural plant progesterone – no adverse effect on lipid profile – no trials regarding vasomotor symptoms
  • Exercise –beneficial (selection bias)
  • Soy – significant reduction in hot flashes- requires large amounts – lowers LDL
vasomotor symptoms continued
Vasomotor Symptoms(continued)
  • Black Cohosh: significant improvement
  • Dong Quai: no improvement when used alone
  • Evening Primrose Oil: no more effective than placebo
  • Antidepressants: SSRIs – 50% improvement
  • St. John’s Wort: use in mild depression beneficial – for menopausal symptoms – questionable efficacy
  • Other Herbal Supplements/Homeopathy: flaxseed oil, fish oil, omega 3, red clover, ginseng, rice bran oil, wild yam, calcium, gotukola, licorice root, sage, sarsaparilla, passion flower, ginkgo biloba and valerian root – no evidence
menopause preventing cardiovascular disease
MenopausePreventing Cardiovascular Disease
  • Soy: claim based on lipid lowering effects
  • Vitamin C, E, and B Carotene: no good evidence
  • Fish Oil: Omega-3 fatty acids and N-3 polyunsaturated fatty acids – effective for secondary prevention of cardiac events – no large trials as a means of primary prevention in postmenopausal women who are at risk
  • Red Clover: does not improve plasma lipids- no long term studies
menopause preventing bone loss
MenopausePreventing Bone Loss
  • Soy: (i.e., isoflavone) - small studies on postmenopausal women show increase in lumbar spine BMD – no difference in hip
  • Hip Fracture: no studies documenting reduction
  • Magnesium: deficiency may contribute to decreased BMD
summary
Summary
  • Black Cohosh: good for vasomotor symptoms
  • Soy: good for VMS –bone – lowers lipid levels
  • Exercise: good for VMS
  • Fish Oil: good for secondary prevention of cardiac events, not VMS
  • Magnesium: good for bone density – no evidence of prevention of hip fractures
