GDA and type 1 diabetes mellitus: Furthermore, we propose to study the SCT effect by measuring the insulin TTD, HbA1c, c-peptide’s fasting and postprandial levels, and T1DM auto antibodies (zinc transporter 8, glutamic acid decarboxylase (GDA), islet cell cytoplasmic auto-antibodies (ICA) in the beta cell, and insulin auto antibodies to protein tyrosine phosphatase) before and 1, 3, 6, 12, 18, and 24 months after the transplantation and then in yearly follow-up to determine its efficacy on the mentioned parameters.
