ABSTRACT
Summary:Comorbid conditions have not been studied systematically for impact upon patient outcome in the setting of hematopoietic stem cell transplantation (HSCT). Patients formerly excluded from myeloablative transplant due to comorbid illnesses now receive reduced-intensity conditioning regimens; hence, the incidence of comorbid conditions in HSCT recipients is expected to increase. Comorbid grading systems developed without regard for oncology patients have been applied in retrospective fashion to HSCT patients. Two commonly used scales (Charlson Comorbidity Index and the Adult Comorbidity Inventory-27) fail to include critical information: tumor and histologic type/stage, extent of prior treatment, donor stem cell source and cell type and preparative regimen. Further, data are reported in retrospective rather than prospective fashion. Despite limitations, however, such grading systems exhibit ease and utility for evaluation and may have predictive value for patient outcome. Modifying such approaches to include additional factors and appropriate weighting of components may enable an improved comparison of techniques and study results. These scoring systems may elucidate predictors of outcome and disease natural history and enhance statistical efficiency methods of HSCT. Refined scoring could be used effectively to assign patients to differing transplant conditioning regimens, that is, myeloablative vs reduced intensity. Prospective validation of such grading systems is encouraged.Bone Marrow Transplantation (2005) 36, 475–479. doi:10.1038/sj.bmt.1705041; published online 4 July 2005

    Sensitized patients are at high risk for graft rejection during transplantation. It is of interest to investigate the effect of mesenchymal stromal cells (MSCs) in sensitized hematopoietic stem cell transplantation. MSCs were generated from bone marrow cells of BALB/c mice. The molecular markers...

    Rapid identification of a matched unrelated donor is essential for patients in need of hematopoietic SCT. We carried out a retrospective evaluation of 549 unrelated donor searches (UDSs), which were completed in 2005 for 23 German transplant centers. On the basis of the patient's HLA-DRB1 allele...

    Summary:Chronic graft-versus-host disease (cGVHD) occurs in approximately 60–80% of those who survive over 100 days after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the pathophysiology of cGVHD is poorly understood. To gain more insight into the immunological...

    Ocular GvHD affects about 40-60% of patients receiving bone marrow transplantation. Ocular complaints worsen quality of life (QoL), which, besides survival time, is a primary end point in a patient's follow-up. The aim of our study was to assess the ocular surface status and vision-related QoL...
