    Abstract:
    We assessed the plasma corticotropin (adrenocorticotropic hormone) and cortisol responses to ovine corticotropin releasing hormone (oCRH) and the cerebrospinal fluid levels of CRH and corticotropin in alcoholics at various durations of abstinence and compared these variables with age-equivalent controls. Alcoholics who were tested at 1 week of abstinence (n = 11) demonstrated a significantly attenuated corticotropin response to oCRH compared with their response at 3 weeks of abstinence. Nine of these alcoholic patients demonstrated a significantly blunted corticotropin response at both 1 and 3 weeks of abstinence compared with controls (n = 15). A markedly exaggerated corticotropin response to oCRH, associated with tachycardia, was exhibited by 2 alcoholics at both 1 and 3 weeks of abstinence. Alcoholics who were abstinent greater than 3 weeks did not differ in their response to oCRH compared with controls. Controls demonstrated a significant inverse correlation between baseline cortisol levels and the cortisol response to oCRH. This correlation was not evident in any of the alcoholic groups, including those patients who were abstinent greater than 6 months. There was a positive correlation between cerebrospinal fluid concentrations of CRH and corticotropin in all patient groups. These findings indicated that alcoholics have significantly altered hypothalamic-pituitary-adrenal axis functioning up to 3 weeks following the cessation of drinking, with a more subtle impairment present for greater than 6 months following abstinence.
