Adrenocorticotropin and cortisol responses to ovine corticotropin-releasing factor in alcohol dependence disorder. Preliminary report

Abstract

A 100-micrograms bolus of synthetic ovine corticotropin-releasing factor was administered intravenously to 10 nondepressed inpatients suffering from an alcohol dependence disorder. The test was performed during withdrawal and after 4 weeks of abstinence. During withdrawal, the plasma cortisol responses of alcoholic patients and 7 control subjects were similar, except for an earlier decrease of cortisol in the former group. However, after 4 weeks of abstinence, the cortisol response was significantly lower in alcoholic patients than in controls. These abnormalities observed during discontinuance of alcohol consumption may reflect adaptive mechanisms of the hypothalamic-pituitary-adrenal activity which may be previously altered by chronic alcohol intoxication.
