Serum proteomic profiling and haptoglobin polymorphisms in patients with GVHD after allogeneic hematopoietic cell transplantation

چکیده
We studied serum proteomic profiling in patients with graft versus host disease (GVHD) after allogeneic hematopoietic cell transplantation (allo-HCT) by two-dimensional gel electrophoresis (2-DE) and mass spectrometry analysis. The expression of a group of proteins, haptoglobin (Hp), alpha-1-antitrypsin, apolipoprotein A-IV, serum paraoxonase and Zn-alpha-glycoprotein were increased and the proteins, clusterin precursor, alpha-2-macroglobulin, serum amyloid protein precursor, sex hormone-binding globulin, serotransferrin and complement C4 were decreased in patients with extensive chronic GVHD (cGVHD). Serum haptoglobin (Hp) levels in patients with cGVHD were demonstrated to be statistically higher than in patients without cGVHD and normal controls (p < 0.01). We used immunoblotting and PCR in combination with 2-DE gel image analysis to determine Hp polymorphisms in 25 allo-HCT patients and 16 normal donors. The results demonstrate that patients with cGVHD had a higher incidence of HP 2-2 phenotype (43.8%), in comparison to the patients without cGVHD (0%) and normal donors (18.7%), suggesting the possibility that specific Hp polymorphism may play a role in the development of cGVHD after allo-HCT. In this study, quantitative serum Hp levels were shown to be related to cGVHD development. Further, the data suggest the possibility that specific Hp polymorphisms may be associated with cGVHD development and warrant further investigation.

Assessment of Cyclosporine Serum Concentrations on the Incidence of Acute Graft versus Host Disease Post Hematopoietic Stem Cell Transplantation
Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment option for hematological disorders. Cyclosporine (CsA) is one of the major immunosuppressive agents for the prophylaxis against graft versus host disease (GvHD). In this retrospective study, we evaluated the effects of CsA serum levels on the incidence of acute GvHD and transplant outcomes. 103 adult patients rece...

Background : Graft versus host disease (GVHD) is among major complications of allogeneic hematopoietic stem cells transplantation, and also is an important factor affecting the outcome of transplantation. An increased incidence of GVHD has been suggested following allogeneic peripheral blood stem cells (PBSC) transplantation, however, how this affects survival is not yet well clear. In this stu...
