Case Report: Fatal Complications of BK Virus-Hemorrhagic Cystitis and Severe Cytokine Release Syndrome Following BK Virus-Specific T-Cells.

ABSTRACT: BK virus (BKV)-hemorrhagic cystitis (HC) is a well-known and rarely fatal complication of hematopoietic stem cell transplantation (HSCT). Treatment for BKV-HC is limited, but virus-specific T-cells (VST) represent a promising therapeutic option feasible for use posttransplant. We report on the case of a 16-year-old male with dedicator of cytokinesis 8 (DOCK8) deficiency who underwent haploidentical HSCT complicated by severe BKV-HC, catastrophic renal hemorrhage, and VST-associated cytokine release syndrome (CRS). Gross hematuria refractory to multiple interventions began with initiation of posttransplant cyclophosphamide (PT/Cy). Complete left renal arterial embolization (day +43) was ultimately indicated to control intractable renal hemorrhage. Subsequent infusion of anti-BK VSTs was complicated by CRS and progressive multiorgan failure, with postmortem analysis confirming diagnosis of hepatic sinusoidal obstruction syndrome (SOS). This case illustrates opportunities for improvement in the management of severe BKV-HC posttransplant while highlighting rare and potentially life-threatening complications of BKV-HC and VST therapy.

Project description:IntroductionBK virus-associated hemorrhagic cystitis (BK-HC) is a debilitating and poorly understood complication of hematopoietic stem cell transplantation (SCT). Hematuria, dysuria, and other symptoms associated with BK-HC are common in the immediate post-SCT period, making BK-HC difficult to distinguish from other conditions presenting with these symptoms. Despite published criteria for diagnosis, the degree to which these criteria are consistently applied to either clinical diagnosis or to studies informing BK-HC management is unclear. We present a case of BK-HC in a pediatric SCT recipient, and discuss the challenges associated with treatment in the absence of rigorous data to inform clinical management.MethodsWe reviewed all cases of BK viruria at our center in patients undergoing SCT between January 2015 and December 2019. We then performed a scoping review of publications in PubMed addressing BK-HC, specifically focusing on how BK-HC was defined. Publications using the keywords "BK polyomavirus" and "hemorrhagic cystitis" were included if they involved a clinical study of SCT recipients and a full-text article was available in English. Case reports were excluded. Analysis focused on whether BK-HC was explicitly defined and whether the definition incorporated elements of diagnostic criteria published by European Conference on Infections in Leukemia (ECIL).ResultsA total of 30 studies published between January 2018 and 30 June 2021 met criteria for review, including 4 clinical trials, 7 prospective observational studies, and 19 retrospective observational studies. Fifteen of these studies included pediatric patients (7 pediatric only, 8 combined adult and pediatric). Of the 30 publications, 19 included a definition of either BK-HC or BK cystitis, with only five using ECIL criteria, all of which were observational studies. Multiple interventions are described for treatment of BK-HC, including cidofovir, leflunomide, quinolones, hyperbaric oxygen, keratinocyte growth factor, and BK-specific cytotoxic T lymphocytes. However, evidence to support efficacy for any of these interventions is lacking.DiscussionAlthough BK-HC is a well-known complication of SCT, evidence to support available treatment options is limited. Well-controlled studies that incorporate clear diagnostic criteria are needed to better define the risk factors, natural history, and ideal interventions.

Project description:RationaleEffective immunomodulatory therapies for children with life-threatening "cytokine storm" triggered by acute influenza infection are lacking. Understanding the immune profiles of children progressing to severe lung injury and/or septic shock could provide insight into pathogenesis.ObjectivesTo compare the endotracheal and serum cytokine profiles of children with influenza-related critical illness and to identify their associations with severe influenza-associated complications.MethodsChildren with influenza-related critical illness were enrolled across 32 hospitals in development (N = 171) and validation (N = 73) cohorts (December 2008 through May 2016). Concentrations of 42 cytokines were measured in serum and endotracheal samples and clustered into modules of covarying cytokines. Relative concentrations of cytokines and cytokine modules were tested for associations with acute lung injury (ALI), shock requiring vasopressors, and death/ECMO.Measurements and main resultsModules of covarying cytokines were more significantly associated with disease severity than individual cytokines. In the development cohort, increased levels of a serum module containing IL6, IL8, IL10, IP10, GCSF, MCP1, and MIP1α [shock odds ratio (OR) = 3.37, family-wise error rate (FWER) p < 10-4], and decreased levels of a module containing EGF, FGF2, SCD40L, and PAI-1 (shock OR = 0.43, FWER p = 0.002), were both associated with ALI, shock, and death-ECMO independent of age and bacterial coinfection. Both of these associations were confirmed in the validation cohort. Endotracheal and serum cytokine associations differed markedly and were differentially associated with clinical outcomes.ConclusionWe identified strong positive and negative associations of cytokine modules with the most severe influenza-related complications in children, providing new insights into the pathogenesis of influenza-related critical illness in children. Effective therapies may need to target mediators of both inflammation and repair.

Project description:Hemorrhagic cystitis (HC) caused by viral infections such as BK virus, cytomegalovirus, and/or adenovirus after allogeneic hematopoietic stem cell transplantation (allo-HCT) causes morbidity and mortality, affects quality of life, and poses a substantial burden to the health care system. At present, HC management is purely supportive, as there are no approved or recommended antivirals for virus-associated HC. The objective of this retrospective observational study was to compare the economic burden, health resource utilization (HRU), and clinical outcomes among allo-HCT recipients with virus-associated HC to those without virus-associated HC using a large US claims database. Claims data obtained from the Decision Resources Group Real-World Evidence Data Repository were used to identify patients with first (index) allo-HCT procedure from January 1, 2012, through December 31, 2017. Outcomes were examined 1 year after allo-HCT and included total health care reimbursements, HRU, and clinical outcomes for allo-HCT patients with virus-associated HC versus those without. Further, a generalized linear model was used to determine adjusted reimbursements stratified by the presence or absence of any acute or chronic graft-versus-host disease (GVHD) after adjusting for age, health plan, underlying disease, stem cell source, number of comorbidities, baseline reimbursements, and follow-up time. Of 13,363 allo-HCT recipients, 759 (5.7%) patients met the prespecified criteria for virus-associated HC. Total unadjusted mean reimbursement was $632,870 for patients with virus-associated HC and $340,469 for patients without virus-associated HC. In a multivariable model, after adjusting for confounders, the adjusted reimbursements were significantly higher for virus-associated HC patients with and without GVHD compared to patients without virus-associated HC (P < .0001). Patients with virus-associated HC stayed 7.9 additional days in the hospital (P < .0001) and 6.1 additional days (P = .0009) in the intensive care unit (ICU) for the index hospitalization, as compared to patients without virus-associated HC. The hospital readmission rate was higher for allo-HCT patients with versus without virus-associated HC (P < .0001), resulting in 12.9 more days in the hospital (P < .0001) and 7.3 more days in the ICU (P < .0001) after the index hospitalization. Among patients with GVHD, those with virus-associated HC had significantly higher all-cause mortality as compared to those without virus-associated HC (23.2% versus 18.4%; P = .0035). In an adjusted analysis, patients with virus-associated HC had a significantly higher risk of mortality, regardless of the presence of GVHD. When stratified by GVHD, there were no significant differences in the baseline risk for renal impairment; virus-associated HC was associated with increased risk for renal impairment in the follow-up period in patients with or without GVHD (P < .0001 for both). After allo-HCT, patients with virus-associated HC have significantly higher health care reimbursements and HRU, with worse clinical outcomes, including renal impairment, irrespective of the presence of GVHD and significantly higher all-cause mortality in the presence of GVHD. Our results highlight the unmet clinical need for effective strategies to prevent and treat virus-associated HC in HCT recipients that may also reduce costs among these patients.
