To investigate the safety of total body irradiation-based myeloablative conditioning (TBI-MAC) in adolescent and young adult (AYA) Philadelphia chromosome (Ph)-negative acute lymphoblastic leukemia (ALL) patients treated with pediatric protocols, treatment outcomes of 106 AYA patients aged 16-39 years old undergoing allogeneic stem cell transplant (allo-SCT) with TBI-MAC in the first remission were compared according to chemotherapy types before transplant. Pediatric and adult protocols were used in 56 and 50 of the patients, respectively. The cumulative incidence (CI) of non-relapse mortality (NRM) and the overall survival (OS) rates were not significantly different between the pediatric-protocol and adult-protocol group (NRM: 4 % vs.

Prolonged severe neutropenia and mucocutaneous barrier impairment resulting from the conditioning regimen or central venous catheter placement are major risk factors for invasive candidiasis in the early phase after HCT. Graft-versus-host disease (GVHD) and corticosteroid use affect the development of invasive candidiasis in the post-engraftment phase after allogeneic HCT.

We performed a prospective observational study in which 110 patients with MDS who were decided to undergo HSCT were enrolled. Among these 110 patients, 77 patients were enrolled in this study within 1 month from the decision for HSCT.

Thus, understanding commonalities in the pathophysiology of cGVHD and autoimmune diseases, such as the presence of disease-risk HLA alleles, is imperative for developing novel therapies against cGVHD. Alloantibodies against H-Y antigens encoded on the Y-chromosome are well-described risk factors for cGVHD in female-to-male transplantation.

Tax is the most important regulatory protein for HTLV-1. We aimed to reveal a unique amino acid sequence (AA) of complementarity-determining region 3 (CDR3) of the T-cell receptor (TCR)β and TCRα chains of HLA-A*02:01-restricted Tax -specific cytotoxic T cells (Tax-CTLs).

He did not have severe graft-versus-host disease, but he developed interstitial pneumonia six months after transplantation when his oral cyclosporine A (CsA) dose was reduced to 10 mg/day. He was given prednisolone (PSL), which temporarily improved his respiratory condition, but he quickly deteriorated when PSL was reduced.

This study aimed to evaluate the association between candidemia and noninfectious interstitial pneumonia (IP) in allogeneic hematopoietic cell transplantation (HCT) recipients.
Methods: Using a Japanese transplant registry database, we analyzed 9143 pediatric and adult patients with hematological malignancies who underwent their first (n = 7531) or second (n = 1612) allogeneic HCT between 2009 and 2019.
Objectives: Isavuconazole is a convenient triazole antifungal agent with a broad antifungal spectrum. A randomized, open-label study (ClinicalTrials.gov, NCT03471988) was conducted to evaluate the efficacy and safety of isavuconazole in Japanese patients with deep-seated mycoses.

Due to frequent intradialytic hypotension, ultrafiltration with cell-free and concentrated ascites reinfusion therapy (CART) was performed to adequately manage the body fluid status and massive ascites. During HD with CART, her blood pressure was maintained compared with that during HD without CART, and an ultrafiltration volume of 3.

Idiopathic pneumonia syndrome (IPS) is a fatal pulmonary complication after allogeneic hematopoietic stem cell transplantation (allo-HCT). However, it is often difficult to diagnose IPS, since a considerable number of IPS patients are critically ill, which makes it difficult for them to undergo bronchoscopy. In this study, we explored the risk factors of IPS based on two definitions.

Chromosome analysis is a powerful prognostic tool in myeloid malignancies. Recipients who experience relapse after allogeneic hematopoietic cell transplantation (allo-HCT) often show chromosomal changes between diagnosis and relapse. However, the clinical impact of chromosomal changes and the efficacy of post-relapse treatment according to chromosomal changes have not been fully investigated.
