A Pilot Study to Identify the Differences in Adipose Tissue Function After Restoring Normal Glycemic Control Following Pancreas Transplantation

Clinical measures of adipose tissue mass (BMI, waist circumference, waist-to-hip ratio) do
not adequately explain the inter-individual and ethnic heterogeneity in diabetes. . There is
a need to identify novel/universal markers of risk for diabetes (DM) and cardiovascular
disease (CVD). These biomarkers also can become additional outcome measures for an
intervention such as pancreatic/kidney transplant. If biological markers show an improvement
with an intervention before anthropometric changes occur, intermediate outcomes can be an
encouraging finding for practitioners. This study will focus on the central question of
"adipose tissue dysfunction" as mediator of metabolic complications of positive energy
balance, independent of body fat content and distribution. This study will address the
question of effect of hyperglycemia on adipose tissue function independent of body fat mass.
This project will take advantage of unique expertise of our investigators to perform detailed
metabolic studies in patients with diabetes who undergo pancreatic/kidney transplant. The
results of the proposed study will provide support to the novel approach of identifying
adipose tissue dysfunction, rather than obesity and fat distribution, as predictor of
diabetes and CVD across all ethnic groups, age and gender. We will obtain necessary
preliminary data for future grant submissions to support our central hypothesis and develop
stronger interactions within and outside The University of Texas Medical Branch (UTMB) with
clinical investigators in the area of DM and its complications.
