Three cases of urticaria/angioneurotic oedema produced by alcoholic beverages are presented. In two of them, the causative agent was probably yeasts in wines. An intracutaneous test with Candida, a conjunctival provocation test with Candida, and peroral challenge tests with wines were positive in both cases. The symptoms disappeared when the patients went on a low-yeast diet. In the third case, ethanol itself and acetic acid apparently were the factors underlying urticaria. Peroral challenge tests with ethanol, brandy and acetic acid were positive, but those with acetaldehyde remained negative. The patient has been asymptomatic after giving up alcoholic drinks alone.

Urticaria, after ingesting ethanol, is rare. A 36-year-old Caucasian male developed multiple, generalized, pruritic urticarial lesions 5 to 15 minutes after drinking alcoholic beverages of any type. A blinded challenge with 5 mL of chemically pure 95% ethanol in concentrated grape juice caused urticaria and an elevation of plasma histamine. Pure grape juice alone was unreactive. Prick skin tests with Brewers' yeast, ethanol, acetaldehyde, and acetic acid were negative. Hydroxyzine (25 mg, p.o., q.i.d.), given for three days prior to challenge, inhibited skin response and histamine release. Biopsy of the urticarial lesions caused by ethanol ingestion showed mast cell degranulation. In this subject, ethanol appeared to directly affect mast cell mediator release by non-IgE mechanisms.
