Alcoholism-associated hyperhomocysteinemia and previous withdrawal seizures.

Abstract

BACKGROUND:

Higher homocysteine levels were found in actively drinking alcoholics as well as in early abstinent patients. Furthermore, it has been shown that high homocysteine levels predicted first-onset alcohol withdrawal seizures. The aim of the present study was to determine plasma homocysteine levels in actively drinking alcoholics and patients with early abstinence in order to evaluate whether there is an additional association between elevated plasma homocysteine levels and a history of alcohol withdrawal seizures.

METHODS:

Two groups of patients with an established diagnosis of alcohol dependence were studied. Group A comprised 56 consecutively admitted alcoholics who had been abstinent from alcohol between 24 to 72 hours before hospitalization. Group B consisted of 144 consecutively recruited alcoholics who were admitted - acutely intoxicated - for withdrawal treatment. Furthermore, groups were divided into two subgroups: patients with and without a history of alcohol withdrawal seizures.

RESULTS:

Alcoholics of GROUP B with a history of withdrawal seizures had significantly (p<.0001) higher homocysteine levels than actively drinking patients without seizures in their history: 42.0 micromol/l (SD 26.4) versus 22.5 micromol/l (SD 11.4). Using a logistic regression analysis, history withdrawal seizures in Group B but not in Group A patients were best predicted by a high homocysteine level at admission (Wald chi2=15.5, p<.0001; odds ratio 1.11, 95% CI 1.05-1.20).

CONCLUSIONS:

Homocysteine levels on admission may be a useful screening method to identify actively drinking patients with a higher risk of alcohol withdrawal seizures.
