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.

Variations in (%) of SHBG: in monophasic OCs

no weight gain

no acne

no side-effects on lipids

minimal impact on glucose and insulin

less impact on vasomotor system

Clinical benefits of progestins with no androgenic activity

Use of progestins in OC

• different progestins have different interactions with steroid receptors (thus different effects)

• non androgenic progestins can preferably be used with E2

• androgenic progestins can be combined (and often are) with EE

• most of the progestins does not modify coagulation

BP

Increased progestative and antigonadotrophic action , clinicaly insignificant interaction with androgenic receptors

Minimal interaction with glucocorticoid, but noted adhaerence with mineralcorticoid receptor, which can che determine an competitive inhibition with aldosterone, although in doses used in OC it does not seems relevant

Cinetics 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)

 Cyproterone Acetate   Cyproterone Acetate  

Progestin with antiandrogenic 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.».

It has antiandrogenic activity (cca 20% of that one from Ciproterone Acetate) and binding strength for 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 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 caracteristics is blocking the androgenic receptor (1/3 activity of ciproterone acetate).

Does not have androgenic, estrogenic, glucocorticoid or antiglucocorticoide actions.

Levonorgestrel 

Has a very efficient progestative activity, high antigonadotrophic action, strong antiestrogenic activity and a weak androgenic and anabolic activity

Thanks to the strong 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.

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 placeboWomen who are receiving active estrogen will also receive progesterone (the bio-identical human progestin) for 12 days per month.
