Analysis of 71 cases of insulin autoimmune syndrome / 中国免疫学杂志

ABSTRACT

Objective:To know the clinical features of insulin autoimmune syndrome to improve diagnostic level. Methods:Focused oninsulin autoimmune syndrome ( IAS ), to make retrospective analysis by summarizing medical history, clinical manifestations,insulin levels,treatment and prognosis of 71 IAS cases recently fifteen years reported in the literature on CNKI. Results:Among the 71 IAS cases,there were 40 cases with a history of hyperthyroidism,31 cases taking methimazole before onset and 43 cases with hypoglycemic episodes with clear regularity, of which 30 cases hypoglycemic episodes occurred during the night or on early morning. 35 cases had disorders of consciousness and such patients had lower blood glucose level and higher insulin level; 36 cases received hormone therapy with shorter time for IAA turning negative,and 26 cases only stopped taking the causative drug;69 cases have a remission,1 case prognosis was unknown due to auto-discharge,and 1 case dies of combined pleural endotheliomas. Conclusion:IAS is one of the important causes of severe spontaneous hypoglycemia and is clinically relatively rare. It often combines with autoimmune diseases,induced by hydroxyl drug and vulnerable to disturbance of consciousness. Patients who have disorders of consciousness should be treated with hormonotherapy in time. Early identification and appropriate treatment generally lead to good prognosis.
