Allogeneic hematopoietic cell transplantation offers high cure rates for patients with hematological and oncological diseases. Graft-versus-host disease (attack of donor's white blood cells on patient's tissues) is a serious complication also affecting the patient's immune system. Therefore, patients in the early phase after allogeneic cell transplantation are at high risk for severe infectious complications. So far, no predictive biomarkers for the development of the chronic form of graft-versus-host disease are available. By analysing serially immune cell populations of the peripheral blood we will investigate whether certain subsets of cells are associated with development of chronic graft-versus-host disease. In addition, the patients' immune regeneration will be evaluated by serial analyses of peripheral blood immune cell populations 3 months to 2 years after allogeneic cell transplantation.

Primary Outcome Measures:
  • Correlation of perturbed B cell homeostasis with chronic graft-versus-host disease activity of immune system [ Time Frame: October 2007 until December 2010 ]

Secondary Outcome Measures:
  • Difference of time-dependent pattern of immune reconstitution after allogeneic cell transplantation between patients with and without chronic graft-versus-host disease [ Time Frame: October 2010 until December 2010 ]
  • Compare number of clinically defined bacterial, viral and fungal infectious episodes between patients with and without chronic graft-versus-host disease [ Time Frame: October 2007 until December 2010 ]
  • Compare the number of circulating T, DC, NK subsets in patients with and without chronic GVHD to identify their respective role in development and prolongation of chronic GVHD [ Time Frame: October 2007 until December 2010 ]
  • Investigate the impact of different immunosuppressive/immunomodulatory treatments for chronic GVHD on various immune cell populations [ Time Frame: October 2007 until December 2010 ]
  • Assess the chimerism of antigen-presenting cells in circulation and tissue specimens and correlate it with occurrence of chronic GVHD [ Time Frame: October 2007 until December 2010 ]
