Much has been written in the lay literature regarding potential benefits of dehydroepiandrosterone (DHEA). Although it was removed from the over-the-counter market in 1985, the Dietary Supplement Health Education Act of 1994 allowed the drug to be marketed as a food supplement. Because DHEA no longer falls under the scrutiny of the Food and Drug Administration, many unverified claims have been put forth in the press espousing its therapeutic value. This barrage of "infomercials" has left the average American consumer (and health care professional) curious about DHEA and its possible therapeutic utility. One focus of recent research is to define the role of DHEA in diabetes mellitus. Although it has been claimed that decreased levels of endogenous DHEA are associated with diabetes, impaired glucose tolerance, hyperglycemia, and insulin resistance, much of the information is based on cross-sectional studies. Other claims correlate decreased endogenous DHEA levels with adverse cardiovascular effects. Some information is contradictory and indicates high doses of exogenous DHEA may produce adverse cardiovascular effects, an undesirable outcome in patients with diabetes mellitus. At this time, its administration in patients with diabetes is not warranted. Long-term trials evaluating the role of exogenous DHEA and its effect on patients with diabetes should be conducted.
