Q

what happens biologically during the menopause transition
- FSH and LH
- E and P
- flow regularity and amount
- E types

A

↓ number and function of follicles + ↓ response to FSH and LH
No progesterone release = irregular + heavy (may also be lighter)
increased FSH and LH
prev more estradiol -. more estrone
increasing and fluctuating E and decreasing P in perimenopause

Q

how does E changes in menopause cause hot flashes

A

↓E = ↓ endorphin conc in hypothalamus = ↑NE, ↓5HT levels = narrow thermoregulatory zone in hypothalamus (narrowed thermoneutral zone)
KNDy neurons in hypothalamus- control of thermoregulatory centers are stimulated by neurokinin B + inhibited by estrogen
↓ estrogen = hypertrophy of KNDy neurons = ↑activity = hot flashes
Target of new tx approaches for VMS (neurokinin 3 receptor antagonists)

21
Q

describe GSM sx and physiology

A

Degeneration of connective tissue (collagen, elastin, smooth muscle) = vaginal shortening + narrowing
Reduced vaginal blood flow and secretions
↓ Glycogen production = △ vaginal pH from acidic to alkaline (↑pH)
Thinning mucosa + ↓ blood flow = ↓ secretions
Sx: vaginal atrophy (dryness, irritation/ itch, dyspareunia, post coital spotting), lower urinary tract (recurrent UTI, LUTS), sexual fx (low libido)

rapid effects of E on arteries
dilation and NO releasel
26
long term effects of E on CV health
↓atherosclerosis, vascular injury, smooth muscle cell growth ↑ endothelial cell growth
27
midlife changes on bone health
bone loss occurs at faster rate with loss of estrogens = always assess for osteoporosis RFs
28
midlife changes on cognition
estrogens modulate aspects of brain function (hippocampus) → NT (ie 5HT, NE, dopamine, ACh) Loss of estrogens = may affect concentration, memory (esp verbal memory- what was that word?) Eff on cognition LT unknown- is it the loss of estrogens or is it aging
29
early or premature menopause is associated with increased risk of
osteoporosis, CV disease, cog impairment/ memory, early mortality
30
lifestyle management of menopausal sx include
cooling techniques (layers, fan), avoid triggers (excessive alcohol, spicy foods), maintain healthy body weight, smoking cessation, exercise
31
what are phytoestrogens
plant compounds with estrogen like activity but 500-1000x weaker than estradiol
32
3 types of phytoestrogens
isoflavones lignans coumestans
33
3 isoflavones of soy
daidzein, genistein, glycetin
34
isoflavone supplement efficacy, how long to work, cautions
Marginal effect with hot flashes, inconsistent results Takes 8-12wks to work Food is a better source Caution with hormone sensitive cancers and supplements
35
femarelle efficacy
RCT showed ↓in vasomotor sx, no adverse △ in breast or endometrium
36
black cohosh sus mech + AEs + efficacy
may act as a SERM, exact mech unknown most studies have found no effect, but generally well tolerated rare liver damage
37
what hormone replacement to use if pt has had a hysterectomy
E alone - no endometrial protection from systemic E required
38
systemic MHT is safe and effective for
healthy pts <60yrs of age or <10yrs after last menstrual period For early or premature menopause, consider MHT until average age of menopause
39
why is P added in MHT
endometrial protection from systemic estrogen (prevents endometrial cancer)
40
what is E used for in MHT
sx management such as VMS + doses can be adjusted for sx management
41
vaginal estrogen is used for 1. GSM 2. VMS
1
42
what is the most common MHT regimen
EPT continuous
43
what is EPT cyclic
estrogen continuous, progestogen x12-14d
44
what is the timing hyp9othesis
: increased risk of atherosclerosis with age/ time after menopause (E is usually protective and prevents plaque formation) If start E >10yrs after menopause = is actually harmful as it can dislodge the plaques that have already formed due to prothrombotic and proinflamamtory effects of estrogen Primary benefit of MHT is <10yrs after menopause
45
what was the women's health initiative
designed as an RCT to assess if MHT reduced CV morbidity and mortality (CEE and medroxyprogesterone were used)
46
describe the relationship between MHT and VTE
E has a dose dependent procoagulant effect Increased risk of VTE with both WHI-EPT and ET with greatest risk in first year, with familial thrombophilia or other RFs Transdermal E may have lower VTE risk, but are based on obs studies only (may just be d/t lower dose)
47
describe the relationship between MHT and CV risk
Age and time since menopause matter- those at high risk of CVD should avoid MHT (hx VTE, stroke, CHd event) Mod risk with comorbidities may use transdermal or lower dose of E Comorbidities: HPTN, smoking, obesity, DM
48
describe the relationship between MHT and breast cancer
EPT in WHI showed ↑ after 5yrs of use ET alone did not show increase of breast cancer in WHI May be differences in risk with type of progestogens - progesterone may have lower risk compared to synthetic progestins Avoid MHT if personal hx of breast cancer Caution if strong family hx
49
oral estrogen effects (TG, SHBG, TBG, CRP, hormones, lipids)
High first pass eff: ↑TG, SHBG, TBG, CRP Some △ in hormones Improve lipids ↑HDL, ↓LDL
50
when should you choose TD over PO estrogens
Avoid first pass effect: smokers, high TG, HPTN, ↓libido, gallbladder disease, RF for VTE/ CVD For consistent lvls: migraine, shift workers, malabsorption issues
51
0.625mg CEE = ____ 17b-estradiol (oral) = __ug patch = ___pumps estrogel = ___ug EE
1mg 50ug patch 1-2 pumps 5ug EE
52
progesterone doses for systemic HT- continuous and micronized
P: continuous MPA 2.5mg or micronized progesterone 100mg daily// cyclic MPA 5mg or micronized progesterone 200mg F12-14d/mth
53
continuous EPT BTB is expected __________
up to 6-9mths after starting, if >!2 mths = investigate
54
cyclic EPT will lead to bleed when
withdrawal bleed when progesterone is stopped at the end of the 12-14d cycle
55
what is tibolone
Selective tissue estrogenic activity regulator (STEAR)- usually not 1st line Synthetic steroid analogue of the progestin, norethynodrel
56
tibolone is converted into
3 active metabolites with estrogenic, progestogenic, and androgenic activity (doesn’t need + P)
57
androgenic eff of tibolone may help with
libido
58
AEs of tibolone
fatigue, breast tenderness, fluid retention, stomach upset/ nausea, increased appetite Same risk profile as other MHTs
59
advantages of tibolone
less BTB compared to EPT, less mood effects b/c no progesterone
60
tissue selective estrogen complexes combined _____
E with a SERM
61
duavive is
bazedoxifen + CE
62
duavive effects
↓BTB and breast tenderness comp EPT No increase in breast density (cancer)
63
bazedoxifen is a
SERM with antagonistic ER eff on uterus and breast- agonist eff on bones Inhibits endometrial hypertrophy as an antagonist
64
bioidentical hormones are
chemically identical in molecular structure to human hormones
65
most MHT products come from
plant sources
66
biest =
estriol (80%) + estradiol (20%) or estriol (50%) + estradiol (50%)
67
triest =
estriol (80%), estradiol (10%), estrone (10%)
68
T or F:Natural progesterone creams (compounded) should not be used with estrogen for endometrial protection
T- lacks evidence that it will prevent endometrial hyperplasia
69
hormone customization for bioidentical hormones are made based on
blood levels or saliva testing
70
when to d/c MHT
Individualized decision on when to discontinue- decision to continue should be reassessed at regular intervals (ex- annually) No age limit to continue MHT- can be continued as long as individual is getting benefit, even into 60s Baseline risk changes over time
71
nonhormonal options for VMS
SNRIs/SSRIs oxybutynin gabapentinoids clonidine
72
SSRI MOA in VMS
increase 5HT lvls in thermoreg zone
73
gabapentinoids MOA in VMS
for VMS unknown, may have direct eff on hypothalamic thermoreg center
74
clonidine MOA in VMS
centrally acting a2 adrenergic agonist, may decrease vascular reactivity Not as effective as other nonhormonal rx options
75
nonpharm tx for GSM

76

moisturizers and lubricants

what moisturizers can be used in GSM
polycarbophil hyluronic acid
