Secondary leukemia occurring after hematopoietic stem cell transplantation (HSCT) for acute myeloid leukemia (AML) is rare. Secondary AML usually follows autologous and not allogeneic transplants. When a new leukemia develops in a patient successfully treated with an allogeneic HSCT, the possibility of a de novo or secondary leukemia from either the donor or recipient should be considered. We p...

Hematopoietic stem cell transplant (HSCT)-associated thrombotic microangiopathy (TMA) is a complication that occurs in 25% to 35% of HSCT recipients and shares histomorphologic similarities with hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). The hallmark of all thrombotic microangiopathies is vascular endothelial cell injury of various origins, resulting in micro...

Allogeneic hematopoietic stem cell transplantation (HSCT) following myeloablative (conventional) conditioning regimen is associated with a high incidence of transplant-related morbidity and mortality, limiting its use to younger patients without medical co-morbidities. Over the past few years, it has become more evident that the alloreactivity of transplanted donor immunocompetent cells against...

Transplantation of hematopoietic stem cells (HSCT) has become the standard treatment for many patients with congenital or acquired disorders of the hematopoietic system or with chemo-radio or immuno-sensitive malignancies. HSCT has undergone rapid expansion over the past two decades. Despite the high cost and the complexity of the procedure, HSCT has developed in developing countries. The trans...

PURPOSE/OBJECTIVES To identify growth patterns and gastrointestinal (GI) symptoms in pediatric patients during the first four months after hematopoietic stem cell transplantation (HSCT) and to assess whether an association exists between acute graft-versus-host disease (GVHD) and growth pattern changes or GI symptoms. DESIGN A prospective, longitudinal cohort design. SETTING A tertiary chil...

Tumor relapse is the primary cause of mortality in patients with hematologic cancers following autologous hematopoietic stem cell transplantation (HSCT). Vaccination early after HSCT can exploit both the state of lymphopenia and minimal residual disease for generating antitumor immunity. Here, multiple vaccinations using lymphoma cells engineered to secrete heat shock protein fusion gp96-Ig wit...

The idiopathic pneumonia syndrome (IPS) represents a common and often fatal complication of hematopoietic stem cell transplantation (HSCT). Gelsolin is a highly conserved actin-binding protein normally present in plasma that may serve a basic physiological role in limiting acute lung injury of diverse etiologies. We hypothesized that depletion of circulating gelsolin following HSCT might play a...

The immune system of patients with severe combined immunodeficiency (SCID) reconstitutes to a large extent during the first years after hematopoietic stem cell transplantation (HSCT). It was suggested, however, that accelerated loss of thymus output may cause impaired immune function at the long term. To address this issue, we studied patients with SCID who underwent allogeneic HSCT 5 to 32 yea...

BACKGROUND Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered the cornerstone in treatment of hematological malignancies. However, relapse of the hematological disease after allo-HSCT remains a challenge and is associated with poor long-term survival. Chimeric antigen receptor redirected T cells (CAR-T cells) can lead to disease remission in patients with relapsed/refr...

Different molecular aberrations can be discriminated into certain prognostic subgroups in cytogenetically normal acute myeloid leukemia (CN-AML) patients but their impact on allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains controversial and studies from Asian populations are lacking. Forty-two adult non-M3 AML patients receiving allo-HSCT from 2002 to 2009 in southern Taiw...
