Menopause Flashcards
What are some presenting symptoms of early menopause/primary ovarian insufficiency?
Irregular periods, difficulties conceiving, sudden change in menstrual cycle (may have prolonged prodrome of oligomenorrhoea or develop sudden amenorrhoea)
What are the criteria for primary ovarian insufficiency/early menopause?
Irregular menstrual cycles (oligo or amenorrhoea for >4 months) and 2 FSH levels of >25, four weeks or more apart
What should you include in history specific to primary ovarian insufficiency/early menopause?
specific questions around childhood diseases, medications, medical conditions (hypothyroidism, diabetes), hx of CRTx, pregnancy, stress, weight loss, exercise, hyperprolactiemia (headaches and galactorrhoea), androgenic sx, previous uterine surgery (Asherman’s), FHx of premature ovarian insufficiency
What are some causes (and frequencies) of primary ovarian insufficiency/early menopause?
Idiopathic 88%
X chromosome abnormalities e.g. Turners, among others 6.7%
Iatrogenic e.g. CRTx 2.1%
Autosomal causes e.g. FSH receptor mutation 1.6%
Autoimmune causes 0.8%
46XY gonadal dysgenesis 0.5%
What investigations should be done specific to primary ovarian insufficiency/early menopause?
hCG, prolactin, TFTs, FSH x 2, LH, oestradiol, testosterone, day 21 progesterone; AMH may be considered
USS looking at ovarian volume, ET, follicle count
Karyotype – Turners, Y chromosome test, and fragile x
Consider adrenocortical antibodies, TPO antibodies
What are complications of primary ovarian insufficiency/early menopause?
- Reduced life expectancy
- Infertility
- Reduced BMD and increased fractures
- Increased risk of CVD
- Negative psych and QOL as a result
- Sexual dysfunction and dyspareunia
- Increased risk of dementia
What is the treatment of primary ovarian insufficiency/early menopause?
Tend to have more hot flushes - MHT used for symptoms of low oestrogen
Good for the hot flushes
Primary prevention for CV disease, BMD and dementia
Not found to increase the risk of breast cancer before the natural age of menopause – give until the age of menopause then stop
Give bio-identical oestrogen/progesterone replacement where possible and consider testosterone
Contraception still needed as pregnancy is not impossible
What bone mineral density defines osteoporosis?
BMD >2.5 SD below the mean
Note: FRAX score is useful to match bone density and risk factors
What is the treatment for osteoporosis in menopause?
Lifestyle: avoid being underweight, stop smoking/reduce ETOH, PA (e.g. resistance training), falls prevention;
Pharm: vit D, bisphosphonates (1st line), OE2, denosumab or teriparatide (both special authority)
How would you treat surgical menopause?
- Treat urogenital sx/dyspareunia with topical oestrogen therapy
- Treat sexual desire with transdermal testosterone patch/cream (only cream available in NZ); SSRI’s also have some efficacy
How does surgical menopause differ to natural menopause with respect to hormones?
Get a sudden drop in androgen levels ( doesn’t happen in natural menopause) - therefore more likely to report sexual dysfunction
What medications are contraindicated in menopause for those with a hx of ERPR+ Breast Ca?
HRT and tibolone
What treatments can be used when the patient has a hx of ERPR+ Breast Ca?
For vasomotor sx use clonidine, gabapentin, SSRI/SNRI; if also on tamoxifen use Citalopram or venlafaxine
For urogenital sx use vaginal moisturisers, lubricants, or if no benefit discuss with the breast team about use of Ovestin.
x % of women will have vaginal dryness and dyspareunia at menopause?
50% - topical vaginal oestrogen helps
How would you treat low desire in those with menopause? What are the ADRs
Consider testosterone cream (warn it is being used off label).
ADRs: increased hair growth at the site of application or in areas prone to hirsuitism such as the chin and lip. High dose ADRs: acne, hirsutism, voice deepening, androgenic alopecia, and clitoromegaly. If the women does not respond – stop it.
How should you stop HRT/MHT?
You can give women the choice - though quite a lot of them prefer to do a slow taper. You can prescribe ½ doses for them or they can cut tablets or take alternate days and decrease over a few months. Also the matrix patches are good here as women can cut little bits off the patch each week and so decrease the dose - need to continue the progestogen though if they have a uterus until they stop estrogen.
Which sx typically flare when MHT is stopped?
Vasomotor sx
(Vasomotor symptoms improve or resolve spontaneously within a few months to a few years of onset in the majority of women, suggesting that most women should be able to discontinue HT within a few years of starting treatment. Approximately 75% of women who try to stop are able to stop HT without major difficulty)
When should you investigate abnormal bleeding on MHT?
If <6 months since starting continuous MHT and exam, swabs and smear are normal it requires no further investigations for now.
What symptoms can be associated with menopause (the climacteric)?
Heavy periods due to drop in progesterone; irregular (with reducing frequency) and often lighter periods (loss of oestrogen).
Cessation of periods is the only sign that happens to all menopausal women with a uterus.
Urogenital and Vasomotor symptoms: Vaginal dryness, dyspareunia, vaginal itching and burning, urinary frequency and urgency, recurrent low sexual desire.
Psych symptoms: Sleep disturbance, depressive sx, anxiety and irritability, reduced memory and concentration.
Metabolic symptoms: Central abdominal fat deposition, IR, increased risk of T2DM, dyslipidaemia.
Cardiovascular: impaired endothelial function
Skeletal changes: accelerated bone turnover and bone loss, increased bone fracture
What examination and investigations should you do for someone at menopause?
BP, BMI, review recent smears and mammography, confirmatory bloods
What are the evidence based non pharmacological treatments for menopause?
weight reduction, exercise, smoking cessation, behavioural modification, meditation, CBT, paced respiration; avoid hot drinks containing caffeine, avoid spicy food, avoid alcohol, fans on desk and beside the bed, cooling scarves/clothing, wearing layers of loose cotton clothing.
What are the evidence based hormonal pharmacological treatments for menopause?
Gabapentin >900mg/day (ADRs drowsiness, headaches and GI upset);
SSRI/SNRIs (citalopram and venlafaxine);
clonidine;
stellate ganglion block (only if severe debilitating sx where other Rx are contraindicated or ineffective);
Unclear evidence: phytoestrogens, black cohosh, st John’s wort, Chinese herbal medicine.
What are the overall main findings from the Women’s health initiative study?
Combined HRT is associated with increased risk of breast cancer - 6-9 extra cases of breast cancer (baseline 63) per 100 women in 5 years of use (9 in 60-69yr group) with combined vs 2-5 extra with oestrogen only.
Cardiovascular benefits in 50’s and reduction in all cause cardiovascular mortality; neutral risk for women in their 60’s and harm if initiated in 70’s.
4-6 extra cases of endometrial cancer with oestrogen only.
5-8 extra cases of VTE with combined vs oestrogen only with a baseline rate of 26.
1-3 extra cases of stroke with other combined or oestrogen only treatment.
No increased risk of ovarian cancer, CHD or femur fracture.
What are the participant characteristics to consider in WHI?
WHI included 50% of women who were high risk (smokers, BMI, HTN, diabetes, unfavourable gail risk score, ETOH intake) and included women who had previously been on MHT
