The importance of IgG4 in the predictive model of thyroiditis

[摘要] Immunoglobulin (Ig)G4-related sclerosing disease (IgG4-RSD) is a new disease entity first proposed with regard toautoimmune pancreatitis. A 67-year-old male patient was examined because of weight loss and an abdominal pain. Based onthe clinical characteristics, laboratory parameters and ultrasound features, we identified the diagnosis of the IgG4-relatedsystemic disease (IgG4-RSD), that was confirmed by the histopathological analysis after the biopsy of the head of pancreas.After confirmation, we started with the corticosteroid therapy with a good clinical, biochemical and morphological response.During the previous therapy, the disturbance of glucoregulation appeared, so we had to change the modality of treatment.We decided to add Azathioprine to the therapy in a dose of 150 mg/day. We achieved a stable phase of the disease with IgG4.37 g/l and IgG4 0.179 g/l, and with no side effects from the therapy.
