CONTEXT: Allogeneic hematopoietic stem cell transplantation (HSCT) has become a well-defined therapeutic strategy for a wide variety of malignant and non-malignant diseases with curative potential. Immune reconstitution post-HSCT is a complex and dynamic process, achieved in stages, depending on the type of transplant, the characteristics of the donor and the recipient, and the occurrence and stage of the graft versus host disease (GvHD).OBJECTIVE: The objective of our study is to identify the correlations between regenerating cell lineage and the time required for complete reconstitution of the immune status depending on the type of allogeneic transplantation.DESIGN: We retrospectively evaluated 16 patients, who have been undergoing allogeneic transplantation between January 2015 and March 2018, and who survived at least 100 days after transplantation in the Pediatric Department, Fundeni Clinical Institute, Bucharest. We analyzed the immune status (B, T and NK cells) by immunophenotyping, using the following markers: Lambda, Kappa, CD56, CD5, CD19, TCRgd/CD16, CD3, CD38, CD20, CD8, CD4, CD45 at well-defined checkpoint intervals (3, 6, 9, 12, and 24 months after the transplant). Absolute values of each subgroup were calculated using the percentage of each subset and absolute count from the leukocytes. RESULTS: In this study, 16 patients have been undergoing allogeneic HSCT transplantation for malignant and non-malignant diseases. There were achieved 5 haploidentical HSCT, 8 HSTC from a matched unrelated donor (MUD), and 4 matched sibling donor (MSD). 5 patients experienced immune recovery during the first 6 months, the NK cells subset has reconstituted in the first 3 months, and the last one to recover was the T cells subset (CD4+). In our study group, the immune reconstitution rate was 20% for haploidentical transplantation, 37.5% for MUD and 25% for MSD. Moreover, delayed immune reconstitution has been associated with the occurrence/reactivation of viral infections (CMV, EBV, BKV, and JCV) with increased frequency in the post-grafting period.CONCLUSIONS: In our center, patients undergoing transplantation from MSD have the fastest immune reconstitution. The immune reconstitution of patients after allogeneic HSCT influences long-term survival by contributing to the management of infectious complications and of GvHD.

Download and read online ebook The European Blood and Marrow Transplantation Textbook for Nurses write by Michelle Kenyon. This book was released on 2018-03-14. The European Blood and Marrow Transplantation Textbook for Nurses available in PDF, EPUB and Kindle. This book is open access under a CC BY 4.0 license. This textbook, endorsed by the European Society for Blood and Marrow Transplantation (EBMT), provides adult and paediatric nurses with a full and informative guide covering all aspects of transplant nursing, from basic principles to advanced concepts. It takes the reader on a journey through the history of transplant nursing, including essential and progressive elements to help nurses improve their knowledge and benefit the patient experience, as well as a comprehensive introduction to research and auditing methods. This new volume specifically intended for nurses, complements the ESH-EBMT reference title, a popular educational resource originally developed in 2003 for physicians to accompany an annual training course also serving as an educational tool in its own right. This title is designed to develop the knowledge of nurses in transplantation. It is the first book of its kind specifically targeted at nurses in this specialist field and acknowledges the valuable contribution that nursing makes in this area. This volume presents information that is essential for the education of nurses new to transplantation, while also offering a valuable resource for more experienced nurses who wish to update their knowledge.

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is widely used in the treatment of haematological malignancies as a form of immunotherapy acting through a graft-versus-leukemia (GvL) reaction. This curative allogeneic response can be associated with severe drawbacks, such as frequent and severe graft-versus-host disease (GvHD) and a long-lasting immunodeficiency, especially now with the development of innovative strategies such as umbilical cord blood transplantation or transplants from haplo-identical family donors (Haplo-HSCT). In the long-term follow-up of these patients, severe post-transplant infections, relapse or secondary malignancies may be directly related to persistent immune defects. Reconstitution of the different lymphocyte populations (B, T, NK, NKT) and antigen presenting cells of myeloid origin (monocytes, macrophages and dendritic cells) should be considered not only quantitatively but especially qualitatively, in terms of functional subsets. Immune deficiency leading to an increased susceptibility to infections lasts for more than a year. Although infections that occur in the first month mostly result from a deficiency in both granulocytes and mononuclear cells (MNC), later post-engraftment infections are due to a deficiency in MNC subsets, primarily CD4 T-cells and B-cells. T-cell reconstitution has been extensively studied because of the central role of T-cells in mediating both GvHD, evidenced by the reduced incidence of this complication following T-Cell depletion, and a GvL effect as shown by DLI. In the recent years there has been renewed interest in the role of NK-cells, especially in the context of Haplo-HSCT, and in B-cell reconstitution. This Frontiers Research Topic will provide state of the art knowledge of the mechanisms of immune reconstitution in an allogeneic environment, in order to improve monitoring and therapeutic intervention in allo-HSCT patients.

Download and read online ebook Stem Cell Transplantation for Hematologic Malignancies write by Robert J. Soiffer. This book was released on 2004-01-29. Stem Cell Transplantation for Hematologic Malignancies available in PDF, EPUB and Kindle. A comprehensive survey of the current state-of-the-art in hematopoietic stem cell transplantation for malignant disease. The authors focus on the indications and results of transplantation for acute leukemia, chronic myelogenous leukemia, lymphoma, multiple myeloma, and breast cancer. Special attention is given to transplant-related complications, including the pathophysiology and clinical consequences of acute and chronic GVHD, delayed immune reconstitution leading to infectious complications, and organ damage to the lung and liver. Additional chapters address the sources of stem cells and the effects of graft manipulation used to eliminate residual contaminating tumor cells in autologous transplantation, or to reduce the number of T lymphocytes causing GVHD in allogenic transplantation.
