BACKGROUND: It has been reported that total serum IgE is increased in alcohol abusers, but the mechanisms responsible are not known. Production of IgE depends on B-cell stimulation by both antigens and some cytokines, particularly IL-4 and IL-13. Chronic alcoholism and alcoholic liver disease are accompanied by changes in cytokine production. AIM OF THE STUDY: To evaluate if IgE increase in alcoholics could be associated to a ethanol-induced imbalance of the cytokine profile. PATIENTS AND METHODS: A total of 65 patients (53 males and 12 females, aged 47 +/- 12 years), admitted to the hospital because of ethanol abstinence symptoms entered the study. On admission, total serum IgE was measured by chemiluminescent EIA and serum IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, and interferon-gamma were measured by ELISA. Data were compared with those of 40 healthy control subjects. RESULTS: Serum IgE, IL-6, IL-8, IL-10, IL-12, and IL-13 were found to be high in alcoholic patients compared with healthy volunteers. Some parallelism was observed between serum IgE and both serum IL-10 and IL-13 were increased in alcoholics. CONCLUSIONS: Total serum IgE elevation in alcoholics with abstinence syndrome is accompanied by an increase of some type 2 cytokines. Ethanol-induced alterations in the cytokine profile may contribute to increased IgE levels in alcoholics.
