Children with many inherited nonmalignant disorders can be cured or their condition alleviated by hematopoietic stem cell transplantation (HSCT). Umbilical cord blood (UCB) units are a rapidly available stem cell source and offer great flexibility in HLA matching, allowing nearly uniform access to HSCT. Although reduced-intensity conditioning (RIC) regimens promise decreased treatment-related morbidity and mortality, graft failure and infections have limited their use in chemotherapy-naive patients.

Mucopolysaccharidosis type II (MPS II) is a lysosomal storage disease (LSD) caused by a deficiency of the iduronate-2-sulfatase (IDS) that catabolizes glycosaminoglycans (GAGs). Abnormal accumulations of GAGs in somatic cells lead to various manifestations including central nervous system (CNS) disease. Enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT) are the currently available therapy for MPS II, but both therapies fail to improve CNS manifestations. Read More

In the last few years, more children and adolescents healed from leukemia go back to their daily life, even if they can show some psycho-social difficulties. The study adopted semi-structured interviews and a mixed-method approach to examine the narratives of 75 children and adolescents about their return to school post 2-years treatment for leukemia. The aims are to collect their illness experiences, to understand how they feel about school and daily routines and to identify the best socio-demographic and illness predictors of a good re-adaptation to school and daily life.

Inherited bone marrow failure syndromes (IBMFS) are a group of cancer-prone genetic diseases characterized by hypocellular bone marrow with impairment in one or more hematopoietic lineages. The pathogenesis of IBMFS involves mutations in several genes which encode for proteins involved in DNA repair, telomere biology and ribosome biogenesis. The classical IBMFS include Shwachman-Diamond syndrome (SDS), Diamond-Blackfan anemia (DBA), Fanconi anemia (FA), dyskeratosis congenita (DC), and severe congenital neutropenia (SCN). Read More

Graft-versus-host disease (GVHD) is a common complication of hematopoietic stem cell transplant, which is known to be mediated by cytotoxic T-cell effectors and dysregulated inflammatory cytokines. Similarly, the lung injury observed in severe COVID-19 cases appears to be related to a massive production of proinflammatory cytokines. The selective JAK1/2 inhibitor ruxolitinib has shown promising results in the context of GVHD, and different trials are currently underway in patients with severe COVID-19; nevertheless no clinical observation of safety or efficacy of treatment with ruxolitinib in this context has been published yet.

The use of cyclophosphamide (CY) for bidirectional tolerization of recipient and donor T cells is associated with reduced rates of graft versus host disease (GVHD) and non-relapse mortality (NRM) after human leukocyte antigen (HLA) matched hematopoietic stem cell transplantation (HSCT). However, recurrent disease remains the primary barrier to long term survival. We extended our two-step approach to HLA matched related HSCT using a radiation-based myeloablative conditioning regimen combined with a high dose of T cells in an attempt to reduce relapse rates while maintaining the beneficial effects of CY tolerization.

Currently, the prognosis of Ph+ acute lymphoblastic leukemia (Ph+ ALL) patients relapsing after an allogenic hematopoietic stem cell transplantation (allo-SCT) remains poor, with few therapeutic options available. Here we present the case of a 32 years old patient with dasatinib-resistant post-transplant molecular relapse of ALL, who received, as second-line therapy, the combination of ponatinib and donor lymphocyte infusion (DLI).

Graft-versus-host disease (GVHD) is a potentially fatal complication of allogeneic hematopoietic stem cell transplantation. The gastrointestinal tract is a major target organ of GVHD, and disruption of the barrier function of the intestinal mucosa leads to an influx of danger signals derived from intestinal microbiota, which may further exaggerate GVHD. We have shown that the recombinant human R-spondin1 protects intestinal stem cells against GVHD, improves intestinal dysbiosis, and ameliorates GVHD. Read More

Background: Delirium is a highly prevalent and preventable neuropsychiatric condition with major health consequences. Thiamine deficiency is a well-established cause of delirium in those with chronic, severe alcoholism, but there remains an underappreciation of its significance in non-alcoholic populations, including patients with cancer. Treatment of suspected thiamine-related mental status changes with high dose intravenous (IV) thiamine has preliminary evidence for improving a variety of cognitive symptoms in oncology inpatient settings but has never been studied for the prevention of delirium in any population.

Aplastic anaemia is a rare, previously fatal condition with a significantly improved survival rate owing to advances in understanding of the pathophysiology and improved treatment strategies including haematopoietic stem cell transplantation. Although a rare condition, aplastic anaemia continues to present a high burden for affected patients, their families and the health system due to the prolonged course of disease often associated with high morbidity and the uncertainty regarding clinical outcome. Modern molecular and genetic techniques including next-generation sequencing have contributed to a better understanding of this heterogeneous group of conditions, albeit at a cost of increased complexity of clinical decision-making regarding prognosis and choice of treatment for individual patients.
