Abstract/OtherAbstract:
Chronic inflammation and decreased frequency of regulatory T cells (Tregs) in visceral adipose tissue contribute to the propagation of insulin resistance to diabetes mellitus. We tested the hypothesis that new-onset post-transplant diabetes mellitus (PTDM) is associated with measurable changes in Treg subsets following allogeneic hematopoietic stem cell transplantation (HCT). PTDM before day+100 and Treg phenotype at engraftment were determined in 36 HCT recipients without preceding history of diabetes mellitus. Among patients with new onset PTDM (N= 24), the frequency of circulating CLA(+) (skin-homing) Tregs was decreased (1.53% vs. 3.99%; P=0.002) and the percentage of α(4)β(7)(+) (gut-homing) Tregs was increased (17.9% vs. 10.7%; P=0.048). In multivariate analysis patients with PTDM continued to demonstrate elevated ratios of α(4)β(7)(+) Tregs to CLA(+) Tregs (odds ratio, 18.1; P=0.020). PTDM is associated with altered immune regulation post-HCT and could represent a target to modulate alloreactivity.
