The role of viral diversity in the pathogenesis of BK polyomavirus (BKPyV)-associated disease is poorly understood. Here, we report near full-length BKPyV genome sequences from two allogeneic hematopoietic cell transplant recipients infected with BKPyV genotype II, which is uncommon in the USA.

Background: Chronic graft-vs-host disease (cGvHD) is a severe immune-mediated complication that affects patients following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Oral manifestations of cGvHD, such as ulcers and mucosal inflammation, significantly impair quality of life and often require long-term treatment. Existing therapies provide limited relief, prompting the exploration of new approaches, including the use of autologous platelet lysate (PL) gel for its regenerative properties.

Primary or secondary hypogammaglobulinemia is associated with persistent norovirus and infections despite immunoglobulin replacement therapy. Allogeneic hematopoietic cell transplantation for hematologic indications can lead to immune reconstitution by correcting a previously undiagnosed concurrent primary immunodeficiency.

Background: Despite decades of post-allogeneic hematopoietic cell transplantation (HCT) growth factor utilization, its role remains undefined, leading to ongoing debates and research. The theoretical impacts of growth factors have been challenged in numerous studies.
Methods: In this retrospective cohort study conducted at the Princess Margaret Cancer Centre, we analyzed the clinical outcomes of 509 patients who underwent allogeneic HCT between May 1, 2019, and May 31, 2022.

Whether the fat-soluble vitamins A, D, E, and K are associated with development of graft-versus-host disease (GvHD) after allogeneic stem cell transplantation, is unclear. We assessed if the levels of these vitamins were associated with development of GvHD during the first year after transplantation using data from a two-armed randomized nutritional intervention trial. Changes in plasma levels during 1-year follow-up were analyzed using a linear mixed model for repeated measurements.

Unlabelled: Minimal residual disease (MRD) is the most important prognostic factor for B-cell acute lymphoblastic leukemia (B-ALL) however nearly 20-30% of patients relapsed even when they achieved negative MRD, how to identify these patients is less addressed. In this study, we aimed to reassess the prognostic significance of MRD and IKZF1 in adult B-ALL patients receiving pediatric chemotherapy regimens. In the PDT-ALL-2016 cohort (NCT03564470), adult B-ALL patients were treated with a pediatric-inspired regimen; patients were redefined as standard (MRD-negative and IKZF1wild-type), intermediate (MRD-positive or IKZF1 deletion), and high-risk (MRD-positive and IKZF1 deletion) groups by combining IKZF1 deletion status and MRD.
