Immune reactions are among the most serious complications observed after hematopoietic stem cell transplantation (HSCT) in children. Microarray technique allows for simultaneous assessment of expression of nearly all human genes. The objective of the study was to compare the whole genome expression in children before and after HSCT. A total of 33 children referred for HSCT were enrolled in the study. In 70% of the patients HSCT was performed for the treatment of neoplasms. Blood samples were obtained before HSCT and six months after the procedure. Subsequently, the whole genome expression was assessed in leukocytes using GeneChip Human Gene 1.0 ST microarray. The analysis of genomic profiles before and after HSCT revealed altered expression of 124 genes. Pathway enrichment analysis revealed upregulation of five pathways after HSCT: allograft rejection, graft-versus-host disease, type I diabetes mellitus, autoimmune thyroid disease, and viral myocarditis. The activation of those pathways seems to be related to immune reactions commonly observed after HSCT. Our results contribute to better understanding of the genomic background of the immunologic complications of HSCT.

Objectives: Patients with refractory myasthenia gravis (MG) have few treatment options. Autologous hematopoietic stem cell transplantation (HSCT) has been used to treat immune diseases; however, its use in the treatment of MG is not broadly considered. Our objective is to report on the efficacy and safety of HSCT in refractory MG.

Introduction: Thrombocytopenia is a common clinical problem in cancer patients undergoing high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HSCT). It can occur as prolonged isolated thrombocytopenia (PIT) or secondary failure of platelet recovery (SFPR) and may cause potentially fatal bleeding. However, data on the treatment of post-transplant thrombocytopenia is still lacking.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is recommended for patients with KMT2A-rearranged (KMT2A-r) leukemia whereas relapse remains high. We aimed to determine whether intensified conditioning containing decitabine (Dec) could reduce relapse compared with standard myeloablative conditioning in adult patients with KMT2A-r leukemia.
Methods: We performed a multicenter retrospective study at seven institutions in China.

Background: Hematopoietic stem cell transplantation (HSCT) patients often receive consecutive intensive chemotherapy, which can lead to gastrointestinal complications and acute graft-versus-host disease (GVHD), placing patients at high nutritional risk.
Aim: This retrospective study aimed to evaluate the benefits of nutritional support in maintaining nutritional status, reducing weight loss without increasing the incidence of catheter-related bloodstream infections (CRBSI) or liver dysfunction, and improving clinical outcomes in HSCT patients at high nutritional risk.
Methods: A total of 526 patients who underwent HSCT were included in the study.

Phthalates and bisphenols, ubiquitous compounds found in various everyday products, have garnered attention due to their potential health-disrupting effects. This study aimed to (1) investigate urinary phthalate metabolites and bisphenol A (BPA) levels in donors and recipients prior to allogeneic hematopoietic stem cell transplantation (HSCT) and monitor changes in these compounds in pediatric recipients at different time points (Day-9, Day 0, Day+7, Day+28, Day+90), and (2) assess their association with engraftment success. Urine samples from pediatric recipients and donors were collected for analysis of phthalate metabolites and BPA in 34 donor-recipient pairs.
