Abstract

Aims: A rare case of the insulin autoimmune syndrome (IAS) accompanied by insulin receptor anomaly is reported. Methods: Antibodies to insulin and insulin receptor were determined in the patient with severe hypoglycaemia before and after the treatment with prednisolone. Results: Titers of antibody to insulin and insulin receptors were 73.0% and 41.5%, respectively. Drug-induced lymphocyte stimulation tests were all negative for the suspicious drugs. Her HLA-DR was DRB1*0403/04051. Following steroid therapy, the formation of antibodies was suppressed and alleviated her symptoms. Scatchard analysis yielded findings specific to polyclonal antibodies. Conclusions: The changes in autoantibodies resulted in alleviation of the hypoglycemic symptoms as a result of steroid therapy.
