Research background

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be related to complications such as graft-versus-host disease (GvHD) and infections. GvHD is a crucial and potentially fatal complication of allo-HSCT. The pathogenesis of this complication is associated with the cytokine storm.

Research motivation

There is a small amount of medical data on the cytokine profiles in patients after allogeneic stem cell transplantation. In this report, the cytokine level was assessed in the early period after allo-HSCT (during the first 30 d after transplantation).

Research objectives

Before, during, and after blood sampling for cytokine determination, cytokine-producing cells were not stimulated with mitogenic substances. Therefore, the obtained cytokine levels and their profiles may be regarded as those which reflect real values in patients who underwent allo-HSCT.

Research methods

We enrolled 62 patients after allo-HSCT due to acute myeloid leukemia (AML). All subjects underwent standard immunosuppressive therapy based on cyclosporin and methotrexate with addition of antilymphocyte globulin in the case of unrelated donor transplantation. Peripheral blood samples were collected from each patient at the checkpoints: Before conditioning treatment, after its completion (day -1), and after transplantation on days +2 +4, +6, +10, +20, and +30, unless death occurred earlier. The samples were not stimulated with mitogenic substances. Serum levels of IL-2 and IFN-gamma were determined using ELISA.

Research results

In the final analysis, patients were divided into four groups based on the occurrence of aGvHD and infection. Significantly higher levels of IFN-gamma were found in group II on days +20 (P = 0.014) and +30 (P = 0.008) in comparison with other groups of patients.

Research conclusions

Higher IFN-gamma levels are more related to infectious complications than the occurrence of aGvHD. Within the first 30 d after allo-HSCT, serum levels of IL-2 in patients with AML are very low and diagnostically insignificant.

Research perspectives

More studies are warranted to create a more precise cytokine profile.
