卵白によるアレルギーが成因と考えられる膵炎の一例

Abstract

A 40-year-old man who had occasionally felt abdominal pain due to unknown causes since his childhood was treated under the provisional diagnosis of ideopathic pancreatitis, because the increases of elastase Ⅰ were simultaneously related to his abdominal complaint without any other findings such as lithiasis, gastrointestinal disease, hyperparathyroidism etc. One day, soon after eating sukiyaki, he suffered from severe epigastralgia more than before. Next day, the laboratory date revealed that the IgE-RAST for egg white was positive and the ratio of eosinocytes in the patient's white blood cells was high, additionally increasing lipase, trypsin and elastase Ⅰ in serum. These clinical features suggest that this case of pancreatitis is related to an allergic reaction by egg white.
