Abstract | BACKGROUND: METHODS: To evaluate the mechanism of hypoglycemia, we measured the inhibition of insulin binding to erythrocytes and IM9 lymphocytes in a sample of the patient's dialyzed serum before and after immunosuppressive therapy. RESULTS: In the patient's pre-treatment serum IgG, the binding of (125)I-insulin to erythrocytes was markedly inhibited in a dose-dependent manner until the cold insulin level reached 10(-9) mol/L. We also observed dose-dependent inhibition of insulin binding to IM9 lymphocytes, which reached approximately 82% inhibition and persisted even when diluted 1:20. After treatment with glucocorticoids, insulin-erythrocyte binding activity returned to between 70% and 80% of normal, while the inhibition of insulin-lymphocyte binding was reduced by 17%. CONCLUSION:
