The main mechanism for the occurrence of TA-GVHD is the transfer of T lymphocytes from the blood donor that damage and promote a response in the tissues of the recipient.
After recognizing host tissues as foreign, the cytokines released by transfused T lymphocytes, such as interleukin-1 IL-1 and tumor necrosis factor TNF , drive an inflammatory response. These cytokines activate inflammatory cells, including natural killer NK cells, macrophages, and other T lymphocytes, resulting in the destruction of host tissues thereby causing TA-GVHD.
However, in immunosuppressed patients, these cells are not destroyed by the recipient's immune system and so after proliferation and producing cytokines, the lymphocytes may cause a TA-GvHD-related inflammatory response. Thus, the only effective method to prevent this disease completely is to inactivate donor lymphocytes by irradiating blood components.
Determination No. Although Vetter and Dodd consider the performance of both methods to be similar, 8 dose uniformity may fail to meet the quality standards in linear accelerators if the method is not standardized. This was also reported by Janatpour et al.
Protocols also differ in respect to the distance between the container and the radiation source, the quantity of bags to be irradiated by each procedure, and the range of results. This study aimed to evaluate the efficiency of irradiation of PRBCs and possible damage to red blood cells using this method.
When fewer than 18 bags are being processed, a special lid was created to reduce the size inside the container in order to better control irradiation. A computed tomography CT of the container was performed to provide images for the Eclipse three-dimensional treatment planning system.

Thus, the only effective method to prevent this disease completely is to inactivate donor lymphocytes by irradiating blood components. The analytical anisotropic algorithm AAA was used to calculate dose distribution in the irradiated material including identifying regions of uneven irradiation.
First, the clinical questions were addressed, and the evidence-based clinical practice guidelines were identified, graded and selected to answer the clinical questions. Conclusion: This paper is an evidence-base approach on the recommendations for transfusion therapy in children with cancer.
Selection of evidence and quality of the clinical practice guidelines The English and Spanish guidelines search comprised from January through December , that yielded , PubMed titles for review see Annex 2.
Se describen las recomendaciones, indicaciones y consideraciones especiales en los distintos procedimientos transfusionales.
