Both autologous and allogeneic hematopoietic stem cell transplants are important therapeutic options for several benign and malignant disorders. Pulmonary complications, although they have become less frequent, remain a significant cause of morbidity and mortality after hematopoietic stem cell transplant. These complications range from bacterial, fungal, and viral pulmonary infections to noninf...

Background: In patients with chronic myeloid leukemia subjected to allogeneic hematopoietic stem cell transplant, the possible negative impact of imatinib therapy in the pre-transplant period is still controversial. Methods and materials: A retrospective study of patients with chronic myeloid leukemia who received allogeneic hematopoietic stem cell transplant between January 2004 and December 2...

Objective(s): Cord blood (CB) is known as a valuable source of hematopoietic stem cells (HSC). Identifying strategies that enhance expansion and maintain engraftment and homing capacity of HSCs can improve transplant efficiency. In this study, we examined different culture conditions on ex vivo expansion and homing capacity of CB-HSCs. Materials and Methods: In this study, 4-5 different units o...

Allogeneic hematopoietic stem cell transplantation is a life-saving procedure for hematopoietic malignancies, marrow failure syndromes, and hereditary immunodeficiency disorders. However, wide application of this procedure is limited by availability of suitably HLA-matched adult donors. Umbilical cord blood (UCB) has being increasingly used as an alternative hematopoietic stem cell source for t...

INTRODUCTION Sinusitis is a common morbidity in general population, however little is known about its occurrence in severely immunocompromised patients undergoing allogeneic hematopoietic stem cell transplantation. OBJECTIVE The aim of the study was to analyze the literature concerning sinusitis in patients undergoing allogeneic bone marrow transplantation. METHODS An electronic database se...

stem cell-based therapies have recently opened up new horizons for treatment of various types of diseases including diabetes mellitus. however, long-term efficacy and safety of these novel modalities still remain a serious question. hereby, we aim to report the one-year follow-up results in the diabetic patients who underwent fetal liver-derived hematopoietic stem cell allotransplantation. fift...

background: the study attempts to assess the relationship between chimerism analysis using polymerase chain reaction of short tandem repeat (str) and the incidence of chronic graft versus host disease (gvhd) as well as survival. methods: the retrospective cohort included all patients who received allo-hsct between 2005 to 2013. data collected by day +100 were reviewed in terms of the incidence ...

RNAi is a powerful method for suppressing gene expression that has tremendous potential for therapeutic applications. However, because endogenous RNAi plays a role in normal cellular functions, delivery and expression of siRNAs must be balanced with safety. Here we report successful stable expression in primates of siRNAs directed to chemokine (c-c motif) receptor 5 (CCR5) introduced through CD...

Major histocompatibility class I deficiency, due to genetic lesions in TAP1, TAP2, TAPBP, or B2M, manifests with recurrent sinopulmonary infections and granulomatous skin ulceration, is predominately treated antimicrobial prophylaxis chest physiotherapy. One previous report of hematopoietic stem cell transplantation has been described the literature, demonstrating cure immune defect without sig...

allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...
