A case of polyglandular autoimmune syndrome type III complicated with autoimmune hepatitis.
A 58-year-old woman complaining of finger tremor was referred to our hospital. The diagnosis of Graves' disease was made based on increased free triiodothyronine (18.88 pg/ml) and free thyroxine (7.47 ng/dl), low TSH (<0.005 microIU/ml) and increased TSH receptor binding antibody activity (70.9%). Serum level of AST (62 U/l) and ALT (93 U/l) were increased and liver biopsy revealed linkage of adjacent portal areas by lymphoplasmacytic infiltrates and fibrosis with piecemeal necrosis. Although antinuclear antibody was negative, these findings indicated that she had autoimmune hepatitis (AIH) according to the criteria of the International Autoimmune Hepatitis Scoring System. Slowly progressive type 1 diabetes mellitus (DM) was confirmed by a diabetic response pattern due to 75 g-oral glucose tolerance test, and seropositivity towards anti-glutamic acid decarboxylase (725 U/ml) and islet cell (80 JDF Units) antibodies. This case exhibited an extremely rare combination of three different autoimmune diseases, including Graves' disease, slowly progressive type 1 DM and AIH, and had no known sensitive human leukocyte antigen (HLA) typing or haplotype for these disorders. Although it is common for patients with Graves' disease to exhibit abnormal liver function, it is important to make an accurate diagnosis of AIH because of this life-threatening disorder.
