Effect of Dehydroepiandrosterone (DHEA) on Hot Flashes in Postmenopausal Women

2014-07-23 16:45:14 | BioPortfolio

Summary

The purpose of the study is to evaluate the effect of daily oral intake of DHEA 50 mg for 4 months on reducing vasomotor symptoms (hot flashes) compared to placebo administration in postmenopausal women.

Description

Humans, along with the other primates, are unique among animal species in having adrenals that secrete large amounts of the inactive precursor steroids dehydroepiandrosterone (DHEA) and especially its sulfate DHEA-S. The marked reduction in the formation of DHEA-S by the adrenals during aging results in a dramatic fall in the formation of androgens and estrogens in peripheral target tissues, a situation that has been proposed to be associated with age-related diseases including skin atrophy, insulin resistance and obesity. Much attention has been given to the benefits of DHEA administered to postmenopausal women, especially on the bone, skin, vagina and well being after oral as well as percutaneous administration of the precursor steroid.

This study proposes to study the effect of 50 mg oral DHEA capsules during a period of 4 months administered to postmenopausal women experiencing 50 or more moderate to severe hot flushes per week. Participants will be stratified by the number of hot flushes experienced per week. The two strata are: 50-70 or more than 70 hot flushes per week. During the study several biological and clinical parameters will be evaluated, as well as the reduction of the number of hot flashes and improvement of overall quality of life.

Subjects will be evaluated at specific time intervals during the study for the above mentioned parameters as well as tolerability and adverse reactions.

Medical and Biotech [MESH] Definitions

A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.

A sudden, temporary sensation of heat predominantly experienced by some women during MENOPAUSE. (Random House Unabridged Dictionary, 2d ed)

Excess production of ADRENAL CORTEX HORMONES such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE. Hyperadrenal syndromes include CUSHING SYNDROME; HYPERALDOSTERONISM; and VIRILISM.

The circulating form of a major C19 steroid produced primarily by the ADRENAL CORTEX. DHEA sulfate serves as a precursor for TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE.

The inner zone of the adrenal cortex. This zone produces the enzymes that convert PREGNENOLONE, a 21-carbon steroid, to 19-carbon steroids (DEHYDROEPIANDROSTERONE; and ANDROSTENEDIONE) via 17-ALPHA-HYDROXYPREGNENOLONE.
