Acute liver injury that followed food-dependent exercise-induced anaphylaxis.

We describe an unusual case of acute liver injury that followed food-dependent exercise-induced anaphylaxis (FDEIAn). A 45-year-old man who experienced anaphylactic shock induced by postprandial exercise and took alcohol that night was admitted the following day to our hospital because of general fatigue. Laboratory examinations revealed elevated hepatic enzymes (aspartate aminotransferase (AST) 6,110 IU, alanine aminotransferase (ALT) 4,178 IU). He had two similar episodes in the past. We speculated that acute liver injury in this case might be induced by interaction of anaphylactic shock and alcohol.
