A Case of Anti-GAD Antibody-Positive Diabetes with Idiopathic Thrombocytopenic Purpura (ITP)

Abstract

A 78-year-old man was diagnosed as having diabetes mellitus and Idiopathic Thrombocytopenic Purpura (ITP) in 1988. He was started on 5mg of prednisolone daily in 1993. His blood sugar level gradually increased to 1994, and therefore he was admitted to our hospital and insulin therapy was started in 1997. During the admission period, he was found to have anti-GAD and JA-2 antibodies indicating that he was suffered from type 1 diabetes. We report this case because the occurence of type 1 diabetes with ITP is considered to be relatively rare.
