BK-virus (BKV) is an important etiological agent for late-onset hemorrhagic cystitis (HC) in patients undergoing hematopoietic stem cell transplantation. Late-onset HC causes significant morbidity among these patients. Therapeutic approaches remain predominantly symptomatic. Several treatment options have been used with variable success rates. Cidofovir has the highest specificity against BKV; however, its lack of availability in the majority of countries, high costs and potential nephrotoxic effects limit its use. The present study reports three cases of severe and prolonged BKV-associated HC (BKHC). HC was resolved in all three of the patients using oral levofloxacin. Thus, levofloxacin may be an effective treatment modality for achieving complete clinical and molecular response in patients with refractory, severe BKHC.

Background: BK hemorrhagic cystitis (BK-HC) is a common complication following hematopoietic stem cell transplantation (HSCT), particularly when posttransplant cyclophosphamide (PTCy) is used as graft-versus-host disease (GVHD) prophylaxis. However, comparative studies of BK-HC incidence in matched sibling donors (MSD) and unrelated donors (MUD) often include small haploidentical (HAPLO) donor cohorts and usually lack detailed information on disease evolution, coinfections, management and impact on outcomes.
Objectives: This study aimed to evaluate the incidence, risk factors, and outcomes in patients with hematologic malignancies undergoing HSCT from MSD, MUD, HAPLO donors using PTCy as GVHD prophylaxis.

Background: Haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) serves as an important option for patients without an HLA matched donor in treating hematological disorders, while patients may experience various complications after transplantation. Mycophenolate mofetil (MMF), a cornerstone drug for graft-versus-host disease (GvHD) prophylaxis, effectively reduces the incidence of acute GvHD, and the efficacy of MMF varies among individuals associated with MMF-related transporters and metabolic enzymes single nucleotide polymorphisms (SNPs). However, limited studies have systematically reported the correlations between the MMF-related SNPs and post-transplant complications.

Background: Hemorrhagic cystitis (HC) is a serious complication following hematopoietic stem cell transplantation (HSCT) associated with significant morbidity and mortality. Early identification of at-risk patients and prompt diagnosis are crucial for effective management. This prospective cohort study evaluated the potential of uroflowmetry as a predictive tool for detecting HC in pediatric HSCT patients.

: Radiation therapy (RT) plays a crucial role in managing prostate cancer, offering effective disease control and improving survival rates in both localized and recurrent cases. However, RT can lead to hemorrhagic cystitis, a significant late complication resulting in chronic morbidity and other health issues. This study aims to evaluate the real-world incidence of radiation-induced hemorrhagic cystitis requiring surgical intervention.
