Background
Systemic immunoglobulin light-chain amyloidosis (AL) is a plasma cell dyscrasia resulting in multisystem organ failure and death. Autologous hematopoietic stem-cell transplantation (ASCT) has been widely used to treat patients with AL. However, treatment-related mortality remains high and reported series are subject to selection bias.Methods
To define the role of patient selection in stem cell transplantation, we evaluated 24 consecutive AL patients transplanted at our center.Results
Complete hematologic response was achieved in all 20 patients surviving >100 days posttransplantation. The 1-year overall survival (OS) rate after ASCT was 78.5%. The 5- and 10-year progression-free and OS rates were 57% and 47%, respectively. Treatment-related deaths owing to cardiovascular problems occurred in 16% of cases.Conclusion
ASCT for AL amyloidosis can be safely performed in experienced transplantation centers, and increased risk is associated mainly with cardiovascular system involvement. 相似文献3.

Osteopetrosis is a rare skeletal dysplasia resulting from an osteoclast defect leading to increased bone mass and density. Hematopoietic stem cell transplantation can rescue the disease phenotype and prevent complications. However, little is known about the skeletal changes hematopoietic stem cell transplantation induces in patients with this disease. The purpose of this study was to describe the skeletal changes after hematopoietic stem cell transplantation in a retrospective cohort of patients diagnosed with osteopetrosis in one medical center over 13 years. For this purpose, all available epidemiological, hematological, biochemical, and radiographic data were collected and quantitatively analyzed. We found a significant early change in bone metabolism markers coinciding with hematopoietic recovery after stem cell transplantation. Hematopoietic stem cell transplantation induced a later significant improvement in both skeletal mineral distribution and morphology but did not lead to complete radiological normalization. Presumably, changes in bone metabolism, skeletal mineral distribution, and morphology were the result of renewed osteoclast function enabling bone remodeling. We propose that biochemical bone metabolism markers and radiological indices be routinely used to evaluate response to hematopoietic stem cell transplantation in patients with osteopetrosis. © 2020 American Society for Bone and Mineral Research. 相似文献

The plasma cell dyscrasias (PCDs) include a number of entities such as multiple myeloma, primary amyloidosis, and monoclonal immunoglobulin deposition disease. Hematopoietic cell transplant (HCT) is the only cure for a variety of hematologic and oncologic diseases. Clinically significant renal impairment is a common feature in plasma cell myeloma, affecting 20% to 55% of patients at initial diagnosis; 2% to 3% of patients present with failure sufficiently severe to require hemodialysis.This circumstance is associated with a high early mortality. The necessity for immunosuppression after HCT could complicate its management and may precipitate the development of complications. In some patients an effective alternative could be kidney transplant (KT); however, the presence of 2 transplants will require optimal adjustment of immunosuppression and management of complications.At present, there are few published cases of KT after HCT, and the experience of managing 2 transplants is limited. We would like to describe our experience with 4 patients who had a PCD and initially received HCT and received subsequent KT.In our experience the progress and outcome of KT after HCT were optimal. We would like to address that a higher incidence of cytopenia associated with the combination of immunosuppression (lenalidomide, tacrolimus, mycophenolate, etc.) and other drugs (ie, valganciclovir) should be considered together with an increased risk of opportunistic infections and PCD relapse. 相似文献

The practice of hematopoietic stem cell transplantation to rescue patients from the myeloablative effects of chemo- or radiotherapy, or to replace defective hematopoiesis, is based on the assumption that hematopoietic stem cells in the graft have sufficient proliferative potential to supply mature blood cells for the remainder of the recipient’s lifespan. However, the mechanism(s) whereby this is achieved are not well understood. Here we address the reconstruction of the hematopoietic system by considering the effects of stem cell and progenitor cell renewal and differentiation. We conclude that stem cell self-renewal is necessary for hematological recovery and that infused committed progenitor cells (CFU-GM) may contribute to the neutrophil count in the early posttransplant period. 相似文献

Mevalonic aciduria because of mutations of the gene for mevalonate kinase causes limited synthesis of isoprenoids, the effects of which are widespread. The outcome for affected children is poor. A child with severe multisystem manifestations underwent orthotopic liver transplantation at age 50 months for the indication of end‐stage liver disease. This procedure corrected liver function and eliminated portal hypertension, and the patient showed substantial improvement in neurological function. However, autoinflammatory episodes continued unabated until hematopoietic stem cell transplantation was performed at 80 months. Through this complex therapy, the patient now enjoys a high quality of life without significant disability. 相似文献

Introduction
Iron overload is an important problem in candidates for and survivors of hematopoietic stem cell transplantation (HSCT), and affects long-term outcome and survival. The objective of the present study was to determine the effect of iron overload on early toxic or infectious complications and survival.Patients and Methods
We retrospectively reviewed the medical records for 250 adult patients (162 men and 88 women; median [range] age, 34 [16-71] years who underwent HSCT between September 2003 and August 2008. The HSCT grafts were autologous in 102 patients, and allogeneic in 148.Results
Follow-up was 315 (1-1809) days. Mean (SD) pre-HSCT serum ferritin concentration was 1402.6 (5016.2) ng/mL in the entire group, 647.6 (1204.3 ng/mL in autologous recipients, and 1410.6 (2410.4) ng/mL in allogeneic recipients. Twenty-eight autologous graft recipients (27.4%) and 102 allogeneic recipients (68.9%) demonstrated serum ferritin concentrations of 500 ng/mL or greater, and were classified as the high-ferritin group. High ferritin concentrations were significantly associated with toxic or infectious complications including mucositis, fungal infections, pneumonia, and sinusoidal obstruction syndrome in the early post-HSCT setting. A significant effect of pre-HSCT ferritin concentration on overall survival and transplant-related mortality was observed. The effect of pre-HSCT ferritin on survival was independent of the comorbidity index at Cox regression analysis. In the entire study population, the probability of survival was significantly lower when ferritin concentration was greater than 500 ng/mL.Conclusion
Transplant-related mortality has decreased substantially with the development of supportive treatments. Pretransplantation risk assessment and risk-adapted strategies such as decreasing iron overload might further improve transplant-related complications. 相似文献18.

Pulmonary complications may occur after hematopoietic stem cell transplantation for hematologic malignancies. Lung transplantation is the only treatment option for end-stage lung failure. We presented a case of acute myeloid leukemia who received a hematopoietic stem cell transplantation and underwent bilateral lung transplantation with end-stage usual interstitial pneumonia and chronic obstructive lung disease. This case showed that lung transplantation could be successfully applied in properly selected hematologic malignancy patients with long disease-free survival, like lung transplantations performed for other indications. 相似文献

We retrospectively analyzed the data of 175 patients who underwent autologous (n = 69) or allogeneic hematopoietic stem cell transplantation (HCT) (n = 106) including 19 (27.5%) and 38 (35.8%) recipients who had bone marrow fibrosis (BMF) prior to transplantation, respectively. We investigated the effects of BMF on engraftment, graft-versus-host disease (GVHD), early posttransplant complications, and survival. Pretransplantation BMF did not delay engraftment and showed no impact either on early posttransplant complications or on the development of acute and/or chronic GVHD. Probability of 1-year overall survival (OS) and progression-free survival (PFS) of autologous HCT recipients were similar, namely 76.7% versus 88.6% (P > .005) and 26.33% versus 16.5% (P > .05) among patients with versus without fibrosis, respectively. In allogeneic HCT recipients, the probability of 1-year OS was 35.2% among patients with versus 48.9% among those without fibrosis (P = .004) PFS at 1 year was inferior among allogeneic HCT recipients with BMF: 27.8% versus 51.2% (P = .0008). Cox regression analysis revealed BMF to be independently associated with age, Sorror comorbidity index, primary disease, and disease status during HCT (P = .045). 相似文献
