Serum bilirubin subfractions in patients with alcohol abuse during detoxication.
Sera were obtained from 41 alcohol abusers consecutively admitted for detoxication. Blood samples were withdrawn on the second, fourth and seventh days of abstention. Initial bilirubin values were moderately elevated in 10 patients. Determination of the bilirubin subfractions by high performance liquid chromatography showed elevated values of unconjugated (alpha), monoconjugated (beta), diconjugated (gamma) and albumin-bound (delta) bilirubin, in 8, 15, 4 and 15 patients, respectively. During abstention, the total bilirubin value normalized rapidly, only three patients still had values above the upper reference limit after 7 days. In patients with initially elevated values of bilirubin subfractions, only a few had elevated beta and gamma levels on the seventh day, whereas delta levels decreased at a slower rate and remained virtually unchanged. On admission, 27 patients exhibited elevated levels of serum bile acids; these values decreased during abstention and after 7 days only six patients had slightly elevated values. Only five patients had initially elevated levels of alkaline phosphatase (ALP). These became normalized in all but two patients during abstention. The results suggest that mild cholestasis is common among alcohol-abusers without clinically evident liver disease and that these changes are reversible on abstention.
