title: Cigarette smoking is associated with elevated adrenal androgen response to adrenocorticotropin.
abstract: Cigarette smoking alters the pattern of endogenous steroid levels. We examined this phenomenon in two separate male groups. Group A consisted of 189 dyslipidemic men participating in the Helsinki Heart Study and group B of 100 men including patients with heart disease and healthy controls. The subjects in the latter group underwent ACTH-testing. In group A, smokers had significantly higher basal androstenedione and dehydroepiandrosterone sulfate (DHEAS) levels and androstenedione/cortisol ratios than nonsmokers. Mean concentrations of cortisol, dehydroepiandrosterone (DHEA), androstanediol glucuronide, testosterone, and sex-hormone binding globulin (SHBG) did not differ between smokers and nonsmokers. In group B, smokers had lower high density lipoprotein (HDL)-cholesterol and apolipoprotein AI and higher triglyceride levels than nonsmokers. Basal androstenedione and ACTH stimulated androstenedione and DHEA concentrations were higher in smokers. No significant differences were found in basal insulin, SHBG, estrone, estradiol, testosterone, free testosterone, and dihydrotestosterone concentrations between smokers and nonsmokers. These results suggest that smoking decreases the activity of either 21- or 11 beta-hydroxylase in the adrenal cortex, which results in increased secretion of adrenal androgens.
