Alcoholic beverages in acute porphyria.

Abstract

Alcohol consumption habits and the clinical consequences of intake of alcoholic beverages were examined in 254 individuals with a diagnosis of acute intermittent porphyria or variegate porphyria, using a questionnaire. The study failed to demonstrate a connection between the amount of ethanol consumed, or the frequency of ingestion, and the development of symptoms of acute porphyria, other than in extreme consumption patterns. It was concluded that agents in alcoholic beverages other than ethanol play important roles in precipitating the porphyric symptoms. A majority of the individuals were able to identify alcoholic beverages that were less well tolerated and those that were better tolerated. The results suggest that polyphenolic compounds and 3 to 5 carbon chain hydrophobic alcohols may be responsible for the induction of clinical symptoms in acute porphyria by some alcoholic beverages. On the basis of these findings advice is proposed on alcohol counseling in inducible porphyria.
