Repro Exam 3 Flashcards
(273 cards)
List the criteria for dx of PCOS
ovarian dysfunction
clinical evidence of androgen excess
polycytic ovaires
exclusion of other conditons that cause same signs/sx
Discuss the pathophysiology underlying PCOS including insulin, steroidal hormones, FSH/LH, metabolic effects, androgen effects and origin, effects on endometrium
hyperandrogenism: dysfunctional gonatropin metabolism and excessive androgen production are believed to be downstream consequences of insulin
resistance, deregulation of hypothalamic-pituitary axis (LH/FSH) and possibly
abnormal melatonin levels that hinder LH/FSH balance
Low or
low-normal SHBG with a serum testosterone within the upper end of normal
range may be associated with excess androgen stimulation in target tissues
because of elevated free testosterone
5-alpha reducatse activity is increased
insulin: prompts the ovary theca cells to enhance the synthesis & release of
androgens and indirectly enhance androgen synthesis through modulation of CHO
levels
Discuss the ways hyperandrogenism presents clinically from most common to least common
hirsutism
acne
male pattern balding
What are the mechanisms that underlie CVD in the PCOS patient?
Impairment of cardiac structure & function - inc cardiac size & dec ejection
fraction, inc BP
Endothelial dysfunction - likely 2nd to insulin resistance (IR)
Lipid abnormalities - inc Tg’s, LDL, & dec HDL – likely 2nd to IR
Chronic low-grade inflammation
Cardiopulmonary impairment - dec maximal O2 consumption (2 studies
have shown with PCOS pts) – directly related to IR
What are the MOA that underlie the development of endometrial hyperplasia and carcinoma in the PCOS patient?
Due to anovulation, presence of DM II (hyperinsulinemia) & obesity,
HTN
inc insulin levels associated with inc risk for cancer due to up-regulation of
estrogen-producing aromatase enzyme systems in endometrial glands &
stroma → additive & deleterious results for a pt with both inc insulin &
anovulatory.
inc fasting plasma insulin causes endometrial hyperplasia to advance to
carcinoma 30% of the time.
Anovulation – prolonged exposure to estrogen in the absence of
progesterone.
Dysregulation of endometrial gene expression in PCOS women
accompanies progesterone resistance in the tissue.
Hyperandrogensism – common finding in endometrial cancer. Androgen
receptor & 5α-reductase are present in endometrium with overexpression
of endometrial androgen receptors.
Hypersecretion of LH (modulator of endometrial growth) – evidenced by
ability of LH to promote growth of human endometrial cancer cells in
vitro. LH receptors also are overexpressed in anovulatory PCOS women
with endometrial hyperplasia and carcinoma
What is the initial lab work for dx? What imaging if necessary to meet 2 of the 3 criteria can be ordered?
serum free testerone, total testosterone, FSH/LH,
TVUS
List the goals of medical management for a PCOS patient
Restoring/Induction of ovulation
Normalization of endometrium
Amelioration of symptoms hyperandrogenism
Reduce insulin resistance
Management of underlying of metabolic abnormalities, & reduce risk factors for
type 2 diabetes & CVD
Lifestyle is the first line treatment for PCOS pts with dysinsulinemia, list the lifestyle treatments and what outcomes are shown with each when incorporated
stress management: Stress of all kinds – causes ↑ in adrenaline & norepinephrine → ↑
in blood glucose, dec insulin secretion, ↑ prod but dec utilization, dec inflammation
sleep hygiene: inc appetite and food intake, inc weight gain, inc IR and glucose intolerance
weight loss: inc insulin sensitivity, dec hirtuism, inc SHBG, dac total & free T to normal or near normal levels
Exercise: dec IR, aids in weight loss, inc permeability of glucose into muscle cells w/o insulin
diet: dec insulin, dec inflammation, increase SCFA’s, regularize cycle,

Discuss the forms progesterone/progestins available for PCOS pts and how and when you would prescribe them with doses and C/I
Progesterone: OMP 100-400 mg qhs 10-14 days
every 1 to 2 months, used for protecting endometrium, regulates menstural cycle, treament of endometiral hyperplasia
Progestins: treatment of endometrial hyperplasia, provera (5-10 mg/d), norethindrone acetate (2.5-10 mg/d) either cyclically or continously
Mirena IUD: treatment of hyperplasia/prevention of carcinoma
When is metformin useful with PCOS and how would you prescribe it with doses as well as C/I
restores menstrual cyclicity & ovulation in 30-50% of PCOS pts,
ability to protect endometrium is less well establishes considered second-line
therapy
