Renal Complications after Hematopoietic Stem Cell Transplantation: Role of Graft-Versus-Host Disease in Renal Thrombotic Microangiopathy.

Hematopoietic stem cell transplantation (HSCT) is a widely accepted treatment for mainly hematopoietic disorders. Recent advances in transplantation techniques have increased the number of long-time survivors with chronic kidney disease (CKD). The presence of CKD affects outcomes and is associated with high mortality rates. Therefore, physicians treating transplant survivors should consider renal complications and optimize management of patients with CKD after HSCT. The pathology of CKD after HSCT is affected by many factors, and the causes of renal thrombotic microangiopathy (TMA) are diverse…

Obstructive sleep apnea and craniofacial appearance in MPS type I-Hurler children after hematopoietic stem cell transplantation.

OBJECTIVES: Mucopolysaccharidosis type I (MPS I) is an inherited lysosomal storage disorder characterized by severe multi-systemic organ manifestations including obstructive sleep apnea syndrome (OSAS). Hematopoietic stem cell transplantation (HSCT) is the treatment of choice in severe MPS I (MPS IH, Hurler syndrome). However, the effect of HSCT on OSAS in MPS IH still remains unclear. The purpose of this study was to analyze respiratory patterns during sleep following HSCT in MPS IH children and to relate these findings to craniofacial abnormalities. METHODS: Overnight polysomnographies of n…

Autologous peripheral blood stem cell transplantation for relapsed/refractory HIV-associated lymphoma: a phase II clinical study.

The outcome of relapsed/refractory HIV-associated lymphoma remains poor, even in the era of combined antiretroviral therapy. However, recent reports showed the efficacy of autologous stem cell transplantation (ASCT). We conducted a single-arm, multicenter phase II study in patients with relapsed/refractory HIV-associated lymphoma to assess the safety and efficacy of ASCT. The study included 14 patients with relapsed/refractory HIV-associated lymphoma. Five patients who achieved partial remission or better after the standard salvage regimen proceeded to ASCT.

Impact of Obesity on Clinical Outcomes of Elderly Patients Undergoing Allogeneic Hematopoietic Cell Transplantation for Myeloid Malignancies.

Allogeneic hematopoietic cell transplantation (allo-HCT) is a high-risk treatment option for patients with hematologic malignancies. Advanced age and obesity can impact outcomes after allo-HCT. Previous registry studies of all age groups found that obesity does not affect outcomes. However, obesity can accelerate age-related decline in physical function and exacerbate comorbid conditions in older patients. Studies evaluating the effect of obesity on elderly patients undergoing allo-HCT are lacking. We performed a retrospective analysis of 86 nonobese (body mass index [BMI] <30) and obese (BMI …

Use of hematopoietic cell transplantation in younger patients with acute myeloid leukemia: A National Cancer Database Study.

Younger patients with intermediate or high-risk acute myeloid leukemia (AML) obtain overall survival benefit from the upfront use of hematopoietic cell transplantation (HCT). We queried the National Cancer Database to study 19,897 younger patients (18-60 years) with intermediate or high-risk AML reported between 2003-2012. Multivariable logistic regression analysis was performed to identify variables associated with the utilization of HCT. Approximately 18.5% of younger patients received HCT as a part of initial therapy. A lower rate of utilization of HCT was associated with receipt of care in…

Clinical effects of recombinant thrombomodulin and defibrotide on sinusoidal obstruction syndrome after allogeneic hematopoietic stem cell transplantation.

Sinusoidal obstruction syndrome (SOS) is a lethal complication after hematopoietic stem cell transplantation (HSCT). Defibrotide (DF) is the only drug internationally recommended for SOS treatment in Western countries. Recombinant human soluble thrombomodulin (rhTM), which is promising for the treatment of patients with disseminated intravascular coagulation, is also reported to be potentially effective for SOS. To clarify the safety and efficacy of DF and rhTM, we conducted a retrospective survey of these agents in Japan. Data from 65 patients who underwent allogeneic HSCT and received DF (n …
