Depression of dehydroepiandrosterone in Japanese diabetic men—comparison between non-insulin-dependent diabetes mellitus and impaired glucose tolerance. Eur J Endocrinol 1996;135:101–4. ISSN 0804–4643
Hyperglycemia is known to reduce dehydroepiandrosterone (DHEA) circulating levels; however, the mechanism by which hyperglycemia decreases DHEA is not elucidated. In this study, serum DHEA and DHEA sulfate (DHEA-S) levels were compared in 50 men with non-insulin-dependent diabetes mellitus (NIDDM) and 50 age-matched men with impaired glucose tolerance (IGT) receiving only diet therapy. Serum concentrations of DHEA and DHEA-S in the NIDDM group were significantly lower than in the IGT group (7.8 and 9.7 nmol/l vs 3.4 and 4.9 μ mol/l, respectively; p< 0.01) but there was no significant difference in immunoreactive insulin between the two groups. When the results from both groups were combined, HbA1c was significantly inversely related to DHEA (r = −0.243. p<0.01) and DHEA-S (r = −0.305, p<0.01). Immunoreactive insulin showed no correlation with DHEA and DHEA-S. Multiple regression analysis showed that HbA1c was independently negatively related to both DHEA and DHEA-S. We conclude that hyperglycemia may decrease serum DHEA and DHEA-S in Japanese men with NIDDM, but the depression of DHEA(-S) is independent of serum insulin level.
