Prediction of Rejection in Renal Transplantation by Immune Parameters

چکیده مقاله:
Background: Monitoring of phenotypic characteristics of T-lymphocytes in peripheral blood is commonly performed to give the clinical parameters in the management of kidney transplant recipients. Objective: To predict rejection in renal transplantation by immune parameters. Methods: 16 non-diabetic kidney transplant candidates (4 females and 12 males, age = 20-65 yr, first time transplant) were selected. The transplanted patients were divided into two groups based on the rejection during 3 weeks post transplant: group I (n = 9) without rejection and group II (n = 7) with a rejection episode. Immune parameters including lymphocytes subpopulations (by flowcytometry) and immunoglobulin classes (IgM, IgG, IgA and IgE by nephlometric assay) before and 45 days after transplantation were determined. Results: The results of this investigation showed that the level of immunoglobulin IgG, IgM, IgA and IgE decreased post transplantation due to immunosuppressive drugs. CD3, CD4, CD8 T cells count, CD56 NK cells count and CD20 B cells count pre- and post-transplantation did not show any significant differences. The amount of IgE (220 vs. 462 IU/ml), CD3 (62% vs. 69.7%) and CD4 (35% vs. 41.3%) cells increased in group II during rejection episode pre-transplantation. In addition, IgA increased pretransplantation in group I those without rejection episode in comparison with group II with a rejection episode. Forty five days post transplantation IgA (209 vs. 152 mg/dl), IgG (1009 vs. 703 mg/dl) and CD20 (15% vs. 10%) increased in group I patients. Conclusion: It is suggestive that pre-transplantation increases IgE, CD3 and CD4 are predictive of acute rejection.

متن کاملImmune response and histology of humoral rejection in kidney transplantation.
The adaptive immune response forms the basis of allograft rejection. Its weapons are direct cellular cytotoxicity, identified from the beginning of organ transplantation, and/or antibodies, limited to hyperacute rejection by preformed antibodies and not as an allogenic response. This resulted in allogenic response being thought for decades to have just a cellular origin. But the experimental st...

Immune profiling: molecular monitoring in renal transplantation.
Molecular techniques have become a mainstay for most biomedical research. In particular, sensitive methods for gene transcript detection and advanced flow cytometry have been crucial in fostering our understanding of the basic mechanisms promoting allosensitization and adaptive immune regulation. These technologies have been validated in vitro, and in pre-clinical settings, and as such their cl...
