dehydroepiandrosterone-hdl-c

この研究の注釈：

50mg of DHEA over 12 weeks in healthy postmenopausal women with an average age of 64.6yrs and who were sedentary at the start of the study.

With the introduction of exercise, beneficial changes in body composition were due to exercise and there was no difference in the DHEA group relative to placebo.

A reduction in small dense LDL particles (oxidized LDL usually) was noted.

研究の資金源に関する問題点：

NIH grant, likely a nonissue

この研究の注釈：

50mg of DHEA given for 3 months in a double blind manner to aged men with low circulating DHEA levels but otherwise healthy status was unable to significantly influence any study parameter despite increasing circulating DHEA levels. The only effect that was notable was an increasing trend to increase LDL and Triglycerides, which did not reach statistical significance.

この研究の注釈：

2 months of DHEA supplements, 50mg at bedtime, was able to increase circulating levels of Platelet cyclic guanosine-monophosphate, a biomarker for Nitric Oxide.

It increased testosterone and estrogen, as well as plasminogen activating factor-1. Interestingly, DHEA also lowered LDL. Other biomarkers measured were not significantly affected.

この研究の注釈：

50mg of DHEA take daily for 1 year in otherwise healthy but aged individuals of both genders was able to reduce fasting triglycerides and HDL-C, but was unable to influence other measured parameters and body composition.

この研究の注釈：

DHEA at 50mg for 4 months was unable to influence serum testosterone levels in men, while it increased testosterone levels only in women with low circulating androgens. SHBG dropped in men and women, and DHEA-S in serum increased in both groups.

No effects on carbohydate metabolism or insulin sensitivity were seen. Fat mass decreased, no effects on well being and quality of life were seen.

Patients were hypoadrenics.
