title: [Graves' disease with markedly elevated serum immunoglobulin E].
abstract: A 37-year-old female with Graves' disease was reported. An abnormally high concentration of serum IgE was observed by radioimmuno-sorbent test before treatment. Laboratory findings showed no evidence of atopic diseases or other known diseases with hyperglobulinemia E. There is no reported case of Graves' disease associated with remarkably elevated plasma IgE level. In the present patient, a further elevation of serum IgE concentration was observed when the dose of methimazole reached about 500 mg in total. Allergic mechanism may be the cause of this phenomenon. Serum IgE level was decreased gradually after replacement of methimazole by propylthiouracil. IgE level was not parallel with thyroid functions, and even when her thyroid function was normalized after subtotal thyroidectomy, IgE concentration was still increased around 900 IU/ml. The mechanism of hyperglobulinemia E in this case was discussed.
