Brief Summary

Diabetic patients who have long-term insulin used can product antibody against exogenous insulin, the investigators named this condition Exogenous insulin antibody syndrome (EIAs). Exogenous insulin antibody can cause blood glucose fluctuation, high blood glucose and refractory hypoglycemia, and have a serious impact on the health of diabetic patients. After adding glucocorticoid, some EIAs patients can reduce insulin dosage, correct hypoglycemia, even eliminate insulin antibody in about half a year, and achieve the goal of blood glucose stability. But up to now, there is no study to evaluate the improvement of blood glucose by glucocorticoid intervention in EIAS patients receiving insulin therapy. This project plans to collect 20 cases of EIAS and carry out a randomized, double-blind, placebo-controlled clinical trial to evaluate the improvement of blood glucose by glucocorticoid intervention.

Detailed Description

Diabetic patients who have long-term insulin used can product antibody against exogenous insulin, the investigators named this condition Exogenous insulin antibody syndrome (EIAs).Exogenous insulin antibody can lead to serious clinical consequences , such as blood glucose fluctuations, high blood glucose and refractory hypoglycemia, which is not only affect patients' blood glucose control, but also have a serious impact on the health of diabetic patients. Change to the oral antidiabetic drugs, change the insulin type or add glucocorticoids to the patients with serious disease are the main treatments. However, most of these treatment schemes are case reports, and there is no randomized controlled cohort study on the treatment scheme. The biosynthetic human insulin sequence is exactly the same as that of human insulin. Why do some diabetics have insulin antibody? The investigators speculated that insulin antibody production in some patients with EIAs is related to autoimmune disorder. After adding glucocorticoid, some EIAs patients can reduce insulin dosage, correct hypoglycemia, even eliminate insulin antibody in about half a year, and achieve the goal of blood glucose stability. However, there is no study to evaluate the effect of glucocorticoid intervention on the improvement of blood glucose in the EIAs population. This project plans to collect 20 cases of EIAs and carry out a randomized, double-blind, placebo-controlled clinical trial to evaluate the improvement of blood glucose by glucocorticoid intervention, so as to provide scientific basis for the standardized diagnosis and treatment of EIAs.
