HRT – after HERS, WHI, MWS … • HERS and WHI : study population too old • In spite of negative publication, positive messages for estrogens use • Latest results speak very positively about benefits of estrogens DP – HORMOGIN Sao Paulo 2007
Conclusions after WHI • HT with Prempro (CEE+MPA) should not be used for prevention of CHD in women of this age group • Other therapies, lower doses, other routes of delivery to be studied • Shorter duration of treatment is advised (but for how long?)

Progestins & hemostatic factors No variations in coagulation factors when progestins are administered without estrogens. Progestins with glucocorticoid action increase the procoagulant effects of thrombin (Herkert O 2001) Estrogenicity of COC, indicate an increase of SHBG, and potentialize the risk of DVT.

Clinical benefits of progestins with no androgenic activity • no weight gain • no acne • no side-effects on lipids • minimal impact on glucose and insulin • less impact on vasomotor system
Use of progestins in OC different progestins have different interactions with steroid receptors (thus different effects) non androgenic progestins can preferably be used withE2 androgenicprogestins can be combined (and often are) withEE most of the progestins does not modify coagulation
Increased progestative and antigonadotrophic action , clinicalyinsignificant interaction withandrogenic receptorsMinimalinteraction withglucocorticoid, but notedadhaerence with mineralcorticoid receptor, which can che determine an competitive inhibition with aldosterone, although in doses used in OC it does not seems relevantCinetics similar to levonorgestrel, bioavailability close to 100%, binding to SHBG above 50%. After oral administration, plasmatic pic is reached within 1 hour (increasing with repeated intake to 12-18 hours) Gestodene
High progestative and antigonadotrophic power caracterised by aminimal antiestrogenic action. No estrogenic, gluco and mineralocorticoid effects andlow affinity for androgen receptors.Desogestrel is a prodrug, rapidly trasformed on hepatic level to an active compound (citochrome P450; 3-Ketodesogestrel, etonorgestrel - ETG)Binding to SHBG is above 30%, and 58% to albumins. Bioavailability is 76%. Desogestrel
Cyproterone Acetate Progestin withantiandrogenic activity, thus blocking the action of testosterone in tissues. It is stocked on adipose level, with some residual glucocorticoid activity. Coadjuvant in hirsutism treatment (EE 35mcg/CPA 2mg). «Not used in USA; high estrogen content and collateral hepatic risks; antiacne effect incostante.».
Chlormadinone Acetate It hasantiandrogenic activity (cca 20% of that one from Ciproterone Acetate) and binding strengthfor Progesterone receptor (PR) 1/3 superior to the one of P and a weak binding with glucocorticoid receptors. 17-OH-progesterone derivated. Scarse effect of the first hepatic passage with bioavailability close to 100%.
Drospirenone Drospirenone is an 17-alfa-spirolactone derivative. Antimineralocorticoid activity of drospirenone,similar to the one progesterone, is linked to the action in renin-angiotensine-aldosterone system. Better control of body weight and of hydric retention. Antiandrogenic caracteristicsis blocking the androgenic receptor (1/3 activity of ciproterone acetate). Does not have androgenic, estrogenic, glucocorticoid or antiglucocorticoide actions.
Levonorgestrel Has a very efficientprogestative activity, high antigonadotrophic action, strong antiestrogenic activity anda weak androgenic and anabolic activity Thanks to thestrong antiestrogenic activity of LNG, increase of SHBG, in connection to OC use, is lower than other progestins; but after 1-3 cycles this effects dissapears. LNG is considered as progestin with minor risks of venous tromboembolism (Lidegaard O, 2009 – van Hylckama A, 2009), and is a gold standard in comparison with other progestins in the issue of coagulation profile.

KEEPS is designed to test this theory by recruiting 720 healthy, recently menopausal women for a randomized, placebo-controlled, double-blinded trial of HT for four years. ORAL E/P Five-year, randomized, placebo-controlled, double-blinded study, each participant will be evaluated for four years. Conducted at nine national sites Approximately 720 recently menopausal women ages 42 to 58 is being recruited Study participants will be divided into three groups and will receive either transdermal estrogen (via skin patch), oral estrogen or placebo Women who are receiving active estrogen will also receive progesterone (the bio-identical human progestin) for 12 days per month.
