The purpose of this study is to determine the proportion of patients who become positive for islet-related autoantibodies after immunoglobulin administration by measuring islet-related autoantibodies (GAD antibody, IA-2 antibody, insulin antibody, and ZnT8 antibody) before and after immunoglobulin therapy.
Another purpose is to determine how long it takes for patients who become positive for islet-related autoantibodies to become negative.

Biomarker Kinetics and Incidence Study
Exploratory
Pragmatic
Not applicable
The proportion of patients who seroconvert to positive for one or more islet-associated autoantibodies (GAD antibody, IA-2 antibody, insulin antibody, and ZnT8 antibody) after immunoglobulin therapy (IVIg).
1) The time it takes for islet-associated autoantibodies to become negative again in patients who became positive after receiving immunoglobulin.
2) The incidence of diabetes.
