PRIMARY OBJECTIVES:
I. To determine whether pre-transplant insulin resistance predicts for the development of new onset post-transplant diabetes mellitus (PTDM) in individuals without diabetes undergoing matched related donor (MRD) hematopoietic stem cell transplant (HCT).
II. To define the role of circulating tissue-specific Th1 cells in the development of PTDM.
III. To characterize the phenotype and function of circulating tissue-specific regulatory T cells (Tregs) in HCT recipients with or without PTDM.
OUTLINE:
Patients undergo OGTT and a standard 2-step euglycemic hyperinsulinemic clamp procedure prior to HCT. Patients then undergo repeat OGTT and a 2-step euglycemic hyperinsulinemic clamp procedure once after HCT between days 90-100.

You may be eligible if
Patients undergoing MRD allogeneic HCT
DONOR: Donors undergoing stem cell collection for match related allogeneic stem cell transplant
You may not be if
Patients who have not received an allogeneic HCT
Recent or current history of diabetes mellitus, defined as:1) diabetes therapy within 6 months of enrollment, or 2) fasting blood glucose at "pre-admit" (screening) visit \>= 126 mg/dL
