Human JC and BK polyomaviruses (JCV/BKV) can establish a latent infection without any clinical symptoms in healthy individuals. In immunocompromised hosts infection or reactivation of JCV and BKV can cause lethal progressive multifocal leukoencephalopathy (PML) and hemorrhagic cystitis, respectively. Vaccination with JCV/BKV derived antigen epitope peptides or adoptive transfer of virus-specific T cells would constitute an elegant approach to clear virus-infected cells. Furthermore, donor leukocyte infusion (DLI) is another therapeutic approach which could be helpful for patients with JCV/BKV infections...

To date, only 1 case of BK polyomavirus (BKPyV) encephalitis combined with transplant-associated thrombotic microangiopathy has been reported in a hematopoietic stem cell transplantation (HCT) recipient. We report the case of a HCT recipient who developed thrombotic microangiopathy and subsequent BKPyV encephalitis. She died despite treatment with cidofovir, ciprofloxacin, and intravenous immunoglobulin without improvement in mental status. Early suspicion of BKPyV encephalitis in a HCT recipient presenting with altered mentality and hemorrhagic cystitis is important...

Cyclophosphamide (CPM) is an alkylating agent widely used for the treatment of malignant neoplasia and which can be used in the treatment of multiple rheumatic diseases. Medication administration errors may lead to its reduced efficacy or increased drug toxicity. Many errors occur in the administration of injectable drugs. The present study aimed at structuring a routine for cyclophosphamide use, as well as creating a document with pharmacotherapeutic guidelines for the patient. The routine is schematized in three phases: pre-chemotherapy (pre-ChT), administration of cyclophosphamide, and post-chemotherapy (post-ChT), taking into account the drugs to be administered before and after cyclophosphamide in order to prevent adverse effects, including nausea and hemorrhagic cystitis...

As diagnosis and treatment of cancer is improving, medical and social issues related to cancer survivorship are becoming more prevalent. Hemorrhagic cystitis (HC), a rare but serious disease that may affect patients after pelvic radiation or systemic chemotherapy, has significant unmet medical needs. Although no definitive treatment is currently available, various interventions are employed for HC. Effects of nonsurgical treatments for HC are of modest success and studies aiming to control radiation-induced bladder symptoms are lacking...

Cyclophosphamide and ifosfamide are widely used drugs for malignancies and rheumatologic conditions. One of the most significant adverse reactions to these drugs is hemorrhagic cystitis (HC). Mesna is the most widely used uroprotective agent that acts to neutralize the caustic metabolite, acrolein, responsible for induction of HC. However, mesna is not a perfect alternative and studies since its discovery have investigated the use of alternative drugs and adjuncts to increase mesna's efficacy. This review details some of the recent work into novel uroprotective agents for drug-induced hemorrhagic cystitis...

INTRODUCTION: Hemorrhagic cystitis (HC) represents a challenging clinical entity. While various intravesical agents have been utilized in this setting, limited data exist regard¬ing safety or efficacy. Herein, then, we evaluated the effectiveness and complications associated with intravesical alum instillation for HC in a contemporary cohort. MATERIALS AND METHODS: We identified 40 patients treated with intravesical alum for HC between 1997-2014. All patients had failed previous continuous bladder irrigation with normal saline and clot evacuation...

Cyclophosphamide (CYP) induced hemorrhagic cystitis is a dose-limiting side effect involving increased oxidative stress, inflammatory cytokines and suppressed activity of nuclear factor related erythroid 2-related factor (Nrf2). Thymoquinone (TQ), an active constituent of Nigella sativa seeds, is reported to increase the expression of Nrf2, exert antioxidant action, and anti-inflammatory effects in the experimental animals. The present study was designed to explore the effects of TQ on CYP-induced hemorrhagic cystitis in Balb/c mice...

Adenoviruses (AdVs) are DNA viruses that typically cause mild infections involving the upper or lower respiratory tract, gastrointestinal tract, or conjunctiva. Rare manifestations of AdV infections include hemorrhagic cystitis, hepatitis, hemorrhagic colitis, pancreatitis, nephritis, or meningoencephalitis. AdV infections are more common in young children, due to lack of humoral immunity. Epidemics of AdV infection may occur in healthy children or adults in closed or crowded settings (particularly military recruits)...

BACKGROUND: Batracylin is a heterocyclic arylamine topoisomerase inhibitor with preclinical anticancer activity. Marked species differences in sensitivity to the toxicity of batracylin were observed and attributed to differential formation of N-acetylbatracylin by N-acetyltransferase. A Phase I trial of batracylin in cancer patients with slow acetylator genotypes identified a dose-limiting toxicity of hemorrhagic cystitis. To further explore the metabolism of batracylin and N-acetylbatracylin across species, detailed studies using human, rat, and dog liver microsomal and hepatocyte preparations were conducted...

Post bone marrow transplant patients are susceptible to atypical infections, especially viral pathogens. The risk increases many folds in cases of allogeneic transplantation, which also receive GVHD prophylaxis. Viral pathogens like cytomegalovirus and herpes are the common ones encountered during follow-up period. However, in recent times there have been reports of a variety of disease manifestations of rare viruses like polyoma virus and adenovirus. These viral infections may play a crucial role in morbidity and mortality in immunocompromised patients...

OBJECTIVE: Ifosfamide (IFO) is considered an essential drug for the treatment of pediatric, adolescent and young adult patients with solid tumors. Hemorrhagic cystitis (HC) is one of the dose-limiting toxicity of IFO. However, there are insufficient evidence for risk factor and supportive care of IFO-induced HC. METHODS: In this retrospective study, patients (<30-year-old) with malignant solid tumors who had been treated with IFO-based chemotherapy, were categorized according to the presence or absence of HC, and were analyzed possible risk factors for IFO-induced HC...
