Interleukin 17A (IL-17)-producing CD4(+) T helper type 17 (Th17) cells have recently drawn attention as possible effector cells of acute graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (HCT) in murine models. Their role after allogeneic HCT in humans is unknown. In this prospective study, Th17, Th1/17, and Th1 cells were quantified in the peripheral blood of 80 patients within the first 3 months after allogeneic HCT using intracellular cytokine staining and flow cytometry. Within the observation period, Th1, Th1/17, and Th17 cells did not reconstitute to levels of healthy control subjects. In contrast to Th1 cells, no further expansion of Th1/17 and Th17 cells was observed during the first month after HCT. Antithymocyte globulin during conditioning significantly reduced the frequency of Th1/17 and Th17 cells but not of Th1 cells. Acute GVHD was not associated with significant changes in the size of the Th1, Th1/17, or Th17 cell subsets. Cytomegalovirus reactivation triggered the expansion of all T helper subsets, and Th1 cells showed the strongest increase. In contrast, no significant changes were found in the T helper cell compartment of patients with bacterial infections compared with time-matched control subjects. In conclusion, quantitative reconstitution of Th1, Th1/17, and Th17 cells is impaired within the first 3 months after HCT, especially when antithymocyte globulin is administered during conditioning. Cytomegalovirus reactivation, but not acute GVHD or bacterial infection, triggered the absolute expansion of these T cell subsets. (C) 2013 American Society for Blood and Marrow Transplantation.
