Comparison of physical and emotional side effects of progesterone or medroxyprogesterone in early postmenopausal women.

OBJECTIVE: To compare the mood and somatic effects during the initial 2 months of medroxyprogesterone acetate (MPA) or progesterone combined with conjugated equine estrogen (CEE) in early postmenopausal women. DESIGN: Twenty-three nondepressed, early postmenopausal women (average age, 52.5 years) completed a 91-day, single-blind pilot study with the following sequence of treatments: 1 week of no substance; 2 weeks of placebo; 2 weeks of progestogen only; 1 week of placebo; and 2 months of "standard hormone replacement therapy cycles," which consisted of (in order) 2 weeks of 0.625 mg CEE, 2 weeks of CEE plus progestogen, 2 weeks of CEE, and 2 weeks of CEE plus progestogen. Ten women who completed the study received MPA (5 mg/day) as their progestogen, and 13 who completed the study received micronized, oil-suspended progesterone (200 mg/day) as their progestogen. All participants made daily assessments of mood using the Profile of Mood States and daily recordings of somatic symptoms. All subjects had plasma follicle-stimulating hormone of greater than 35 IU/L and had not had spontaneous vaginal bleeding for more than 1 year. RESULTS: None of the hormone treatments had a detectable effect on mood. MPA users reported more vaginal bleeding and breast tenderness than progesterone users. CONCLUSIONS: In contrast with the widely held belief among psychiatrists that progesterone depresses mood, neither of the progestogens we used in normal, nondepressed and nonanxious women showed this effect. Absence of an effect on mood was also found when the results of the two progestogens were combined. The lesser side effects of the micronized progesterone-containing regimen suggest that some women may prefer it to an MPA-containing regimen.

Dehydroepiandrosterone supplementation and bone turnover in middle-aged to elderly men.

In the present placebo-controlled, double-blind study, we assessed the effect of dehydroepiandrosterone (DHEA) supplementation (90 mg orally/d) on bone turnover in 43 healthy men, 56-80 yr old. Placebo or steroid was given for 6 months, followed by a 1-month washout period and then a further 6 months of the opposite agent. Serum samples were collected at baseline 3, 6, 7, and 13 months and assayed for procollagen peptide, bone-specific alkaline phosphatase, and osteocalcin, all markers of bone formation. Measurements were also made of serum cortisol, DHEA/DHEA-S, E2 and free and total T. First void, fasting urine was collected at baseline, 6, 7, and 13 months and assessed for deoxypyridinoline, a marker of bone resorption. Mean serum DHEA and DHEA-S levels in treated men were increased approximately 3-fold ( approximately 2.2 ng/ml to approximately 6 ng/ml) and 4.5-fold ( approximately 1000 ng/ml to approximately 4500 ng/ml), respectively, after 6 months and returned to baseline after washout. Similarly, circulating E2 concentrations were also increased 1.4-fold (from approximately 16-23 pg/ml; P < 0.001), a finding not observed with any other measured hormone. Bone marker levels remained remarkably constant at each sampling interval; procollagen peptide at approximately 8.0 ng/ml; bone-specific alkaline phosphatase at approximately 21.0 U/liter; deoxypyridinoline at approximately 4.5 nmol/mmol Cr. Osteocalcin showed a transient reduction from approximately 10.2- 6.2 ng/ml, P < 0.005 to P < 0.001, at 3 months, but this decline was observed in both treated and controls. Stratifying the marker levels by age or baseline DHEA/DHEA-S levels did not affect the findings. We conclude that oral DHEA does not affect bone turnover in middle-aged to elderly men when used for a 6-month period at doses targeted to restore circulating levels of the steroid to that seen in young adults.
