The study aims at investigating the relationship between hypothalamic-pituitary-adrenal (HPA) axis alterations and aggression level in alcoholic patients during early and late alcohol withdrawal. Serum levels of basal cortisol and dehydroepiandrosterone sulphate (DHEAS) were measured three times, and cortisol and DHEAS response to dexamethasone twice during the early and late withdrawal periods in alcohol dependent males (n=30) and once in healthy control males (n=20). Abnormal cortisol non-suppression response to dexamethasone in dexamethasone suppression test (DST) was observed in some proportion of the patients in early withdrawal, which normalized in late withdrawal. The study revealed reduced basal DHEAS levels and reduced DHEAS response to dexamethasone in late withdrawal. When the patients were assessed in two separate groups as high- and low-aggressives, in the high-aggression group abnormality in DST was observed during both early and late withdrawal periods, in the low-aggression group it was observed only in early withdrawal. While basal DHEAS levels were low in the high-aggression group only in early withdrawal, it was reduced in the low-aggression group during late withdrawal period. Some alterations of the HPA axis during alcohol withdrawal might be associated not only with alcohol use per se but also with aggressivity tendency of alcoholic patients. (c) 2007 Elsevier Inc.
