Total body irradiation (TBI) is frequently used in hematopoietic stem cell transplantation (HSCT) and is associated with many complications due to radiation injury to the normal cells, including normal stem cells. Nevertheless, the effects of TBI on the mesenchymal stromal stem cell (MSC) are not fully understood. Bone marrow-derived MSCs (BM-MSCs) isolated from normal adults were irradiated with 200 cGy twice daily for consecutive 3 days, a regimen identical to that used in TBI-conditioning HSCT. The characteristics, differentiation potential, cytogenetics, hematopoiesis-supporting function, and carcinogenicity of the irradiated BM-MSCs were then compared to the non-irradiated control...

BACKGROUND: CMV reactivation is a major cause of severe complications in allogeneic hematopoietic stem cell transplant (HSCT) recipients. The risk of CMV reactivation depends on the serostatus (+/-) of the donor (D) and recipient (R). The reconstitution of CMV-specific T-cell responses after transplantation is crucial for the control of CMV reactivation. OBJECTIVES: The study aimed to determine the cellular immune status correlating with protection from high-level CMV viremia (>5000 copies/ml) and disease...

Post-transplant lymphoproliferative disorders (PTLDs) are life-threatening complications of solid-organ transplantation and bone marrow transplantation leading to a high mortality. PTLD represents a heterogeneous group of lymphoproliferative diseases. They become clinically relevant because of the expansion of transplantation medicine together with the development of potent immunosuppressive drugs associated now with long survival. The risk of PTLD is highest in the early post-transplant period, but the cumulative risk increases with time...

Post-operative pancreatic fistula (POPF) following pancreatic resection is a life-threatening surgical complication. Cell sheets were prepared and harvested using temperature-responsive culture dishes and transplanted as patches to seal POPF. Two different mesenchymal stem cell (MSC) sheets were compared in terms of the preventative ability for pancreatic leakage in a rat model. Both rat adipose-derived stem cell (rADSC) and bone marrow-derived stem cell (rBMSC) sheets were transplanted. Those rADSC and rBMSC sheets are created without enzymes and thus maintained their cell-cell junctions and adhesion proteins with intact fibronectin on the basal side, as well as characteristics of MSCs...

Severe aplastic anemia is a rare and potentially life-threatening disease of the bone marrow often requiring allogeneic hematopoietic stem cell transplantation. Pathogenesis of the disease can vary and often remains enigmatic. Occasionally, severe aplastic anemia is associated with prior severe acute hepatitis. Differential diagnosis of acute non-viral hepatitis challenges the physician as pathogenesis remains unclear.We here present a case of a young patient presenting with acute hepatitis followed by severe aplastic anemia successfully treated with allogeneic hematopoietic stem cell transplantation...

PURPOSE: Avascular necrosis of the talus is one of the most notable complications associated with talar neck fractures with frequent evolution of the osteonecrosis into a difficult arthrodesis. We tested whether the injection of bone marrow mesenchymal stem cells (MSCs) could improve the repair process of the osteonecrosis. MATERIAL AND METHODS: Forty-five early (without collapse) post-traumatic talus osteonecroses (group 1; study group) were treated between 1995 and 2012 with percutaneous injection of progenitor cells (autologous bone marrow concentrate from the iliac crest)...

The primary challenge in organ transplantation continues to be the need to suppress the host immune system long-term to ensure prolonged allograft survival. Long-term non-specific immunosuppression can, however, result in life-threatening complications. Thus, efforts have been pursued to explore novel strategies that would allow minimization of maintenance immunosuppression, eventually leading to transplant tolerance. In this scenario, bone marrow-derived mesenchymal stromal cells (MSC), given their given unique immunomodulatory properties to skew the balance between regulatory and memory T cells, have emerged as potential candidates for cell-based therapy to promote immune tolerance...

Patients with inherited bone marrow failure syndromes are usually identified when they develop hematologic complications such as severe bone marrow failure, myelodysplastic syndrome, or acute myeloid leukemia. They often have specific birth defects or other physical abnormalities that suggest a syndrome, and sequencing of specific genes or next-generation sequencing can determine or confirm the particular syndrome. The 4 most frequent syndromes are Fanconi anemia, dyskeratosis congenita, Diamond Blackfan anemia, and Shwachman Diamond syndrome...

Hemorrhagic cystitis is one of the complications of allogeneic hematopoietic stem cell transplantation. Treatment of hemorrhagic cystitis is difficult, especially in pediatric patients. A pediatric case of severe hemorrhagic cystitis after hematopoietic stem cell transplantation was treated in our hospital with arterial embolization combined with corticosteroid therapy because the conventional therapy was invalid for him. After the treatment, hemorrhagic cystitis was cured. During follow-up, the patient was in stable condition, with normal urine, blood cells returned to normal, bone marrow was in complete remission state, and disease-free survival for more than 8 months...

BACKGROUND: Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high-risk patients. Ulceration can lead to severe pain and difficulty with eating and drinking, which may necessitate opioid analgesics, hospitalisation and supplemental nutrition. These complications may disrupt cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients...

Over the last decades, significant advances in the diagnosis and therapeutics have considerably improved success rate from bone marrow transplant in patients suffering from otherwise life-threatening diseases, allowing now for prolonged survival and better quality of life after an allograft. However, infectious diseases remain one of the most serious complication in this population, hence associated with a high morbidity and mortality. Prevention, in particular through vaccination, constitutes a cornerstone of the management of immunocompromised hosts, since this procedure aims to protect them once back to life in community after long periods of hospitalization...

The evolution of HLA typing and transplantation techniques makes it easier to identify a donor for hematopoietic stem cell (HSC) transplantation. This activity, strongly regulated by regulatory or normative texts, implies in addition biological, medical, para-medical and sometimes psychological evaluations. The benefit/risk discussion is complicated because it must take into account the benefit/risk ratio for the recipient, and the donor risk. No Evidence-Based Medicine data is available and serious events are very rare situations...

Since the demonstration that hematopoietic cells are present in circulating blood, peripheral blood stem cell transplantation (PBSCT) has become an area of interest. The invention of growth factors such as the granulocyte colony-stimulating factor (G-CSF) and the availability of apheresis techniques allowed the wide application of peripheral blood stem cells (PBSC) in both autologous and allogeneic hematopoietic stem cell transplantation settings. It has been since 1986 that clinically introduced, peripheral blood stem cells replaced bone marrow as a stem-cell source to nearly 100% in the autologous and to approximately 75% in the allogeneic transplantation setting...
