Project description:BackgroundCytomegalovirus (CMV) infection is a common complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT) and in patients receiving novel hematological therapies. Its impact on morbidity and mortality necessitates effective management strategies. Despite recent advances in diagnostics and treatment, unresolved questions persist regarding monitoring and treatment, prompting the need for updated recommendations.MethodsA consensus was reached among a panel of experts selected for their expertise in CMV research and clinical practice. Key clinical areas and questions were identified based on previous surveys and literature reviews. Recommendations were formulated through consensus and graded using established guidelines.ResultsRecommendations were provided for virological monitoring, including the timing and frequency of CMV DNAemia surveillance, especially during letermovir (LMV) prophylaxis. We evaluated the role of CMV DNA load quantification in diagnosing CMV disease, particularly pneumonia and gastrointestinal involvement, along with the utility of specific CMV immune monitoring in identifying at-risk patients. Strategies for tailoring LMV prophylaxis, managing breakthrough DNAemia, and implementing secondary prophylaxis in refractory cases were outlined. Additionally, criteria for initiating early antiviral treatment based on viral load dynamics were discussed.ConclusionThe consensus provides updated recommendations for managing CMV infection in hematological patients, focusing on unresolved issues in monitoring, prophylaxis, treatment, and resistance. These recommendations aim to guide clinical practice and improve outcomes in this high-risk population. Further research is warranted to validate these recommendations and address ongoing challenges in CMV management with emerging antiviral combinations, particularly in pediatric populations.

Project description:IntroductionStudies addressing the role of haploidentical as alternative to HLA-matched donors for stem cell transplantation (SCT) often include patients with diverse hematological malignancies in different remission statuses.MethodsWe compared outcomes of children with acute lymphoblastic leukemia (ALL) undergoing SCT in second complete remission (CR2) from haploidentical (n = 25) versus HLA-matched donor (n = 51).ResultsPatients were equally distributed across both groups according to age, immunophenotype, time to and site of relapse, relapse risk-group allocation, and minimal residual disease (MRD) before SCT. Incidence of graft failure, acute graft versus host disease (GVHD), and other early complications did not differ between both groups. We found no differences in overall survival (58.7% versus 59.5%; p = .8), leukemia free survival (LFS) (48% versus 36.4%; p = .5), event free survival (40% versus 34.4%; p = .69), cumulative incidence (CI) of subsequent relapse (28% versus 40.9%; p = .69), treatment related mortality (24% versus 23.6%; p = .83), CI of cGVHD (4.5% versus 18.7%; p = .2), and chronic GVHD-free and leukemia-free survival (44% versus 26.3%; p = .3) after haploidentical donor SCT. Chronic GVHD (HR = 0.09; p=.02) had protective impact, and MRD ≥ 0.01% before SCT (HR = 2.59; p=.01) had unfavorable impact on LFS.DiscussionThese results support the role of haploidentical donor SCT in children with ALL in CR2.

Project description:ObjectiveThe COVID-19 pandemic has been difficult for families across the world due to fears about infection risk, increased social isolation, and significant changes in family roles and routines. Families with a child undergoing pediatric hematopoietic stem cell transplant (HCT) may be at even greater risk for poor adjustment during COVID-19 given their child's increased risk for infection. The purpose of the current study was to qualitatively examine the impact of COVID-19 on family adjustment during pediatric HCT to inform clinical care.MethodsTwenty-nine caregivers of children (≤12 years) who underwent an HCT within the past 2 years completed semi-structured qualitative interviews and demographic questionnaires in the first 4 months following initial COVID-19 quarantine.ResultsTwenty-two themes emerged from the interviews using grounded theory methodology. Although nearly half of caregivers described COVID-19 as a stressor, 69% of caregivers reported adequate adjustment to COVID-19. Caregivers generally attributed their positive adjustment to HCT preparing the family for COVID-19 and more difficult adjustment to increased physical or social isolation and COVID-19 amplifying germ fears. The child's HCT treatment status also had important implications on family adjustment to COVID-19.ConclusionsResults suggest that families undergoing pediatric HCT are uniquely prepared to cope with the impacts of a global pandemic; however, families experiencing certain risk factors (e.g., more recent transplant, impaired access to social support, reduced access to coping tools) may experience poorer adjustment during pandemics such as COVID-19 and may benefit from increased psychosocial support from their healthcare team.

Project description:This is a multicenter prospective observational study that included a large cohort (n = 397) of allogeneic (allo-HSCT; (n = 311) and autologous (ASCT) hematopoietic stem cell transplant (n = 86) recipients who were monitored for antibody detection within 3-6 weeks after complete severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination from February 1, 2021, to July 20, 2021. Most patients (n = 387, 97.4%) received mRNA-based vaccines. Most of the recipients (93%) were vaccinated more than 1 year after transplant. Detectable SARS-CoV-2-reactive antibodies were observed in 242 (78%) of allo-HSCT and in 73 (85%) of ASCT recipients. Multivariate analysis in allo-HSCT recipients identified lymphopenia < 1 × 109 /ml (odds ratio [OR] 0.33, 95% confidence interval [95% CI] 0.16-0.69, p = .003), active graft versus host disease (GvHD; OR 0.51, 95% CI 0.27-0.98, p = .04) and vaccination within the first year of transplant (OR 0.3, 95% CI 0.15-0.9, p = .04) associated with lower antibody detection whereas. In ASCT, non-Hodgkin's lymphoma (NHL; OR 0.09, 95% CI 0.02-0.44, p = .003) and active corticosteroid therapy (OR 0.2, 95% CI 0.02-0.87, p = .03) were associated with lower detection rate. We report an encouraging rate of SARS-CoV-2-reactive antibodies detection in these severe immunocompromised patients. Lymphopenia, GvHD, the timing of vaccine, and NHL and corticosteroids therapy should be considered in allo-HSCT and ASCT, respectively, to identify candidates for SARS-CoV-2 antibodies monitoring.

Project description:We report the nationwide experience with solid organ transplant (SOT) and hematopoietic stem cell transplant (HSCT) recipients diagnosed with coronavirus disease 2019 (COVID-19) in Spain until 13 July 2020. We compiled information for 778 (423 kidney, 113 HSCT, 110 liver, 69 heart, 54 lung, 8 pancreas, 1 multivisceral) recipients. Median age at diagnosis was 61 years (interquartile range [IQR]: 52-70), and 66% were male. The incidence of COVID-19 in SOT recipients was two-fold higher compared to the Spanish general population. The median interval from transplantation was 59 months (IQR: 18-131). Infection was hospital-acquired in 13% of cases. No donor-derived COVID-19 was suspected. Most patients (89%) were admitted to the hospital. Therapies included hydroxychloroquine (84%), azithromycin (53%), protease inhibitors (37%), and interferon-β (5%), whereas immunomodulation was based on corticosteroids (41%) and tocilizumab (21%). Adjustment of immunosuppression was performed in 85% of patients. At the time of analysis, complete follow-up was available from 652 patients. Acute respiratory distress syndrome occurred in 35% of patients. Ultimately, 174 (27%) patients died. In univariate analysis, risk factors for death were lung transplantation (odds ratio [OR]: 2.5; 95% CI: 1.4-4.6), age >60 years (OR: 3.7; 95% CI: 2.5-5.5), and hospital-acquired COVID-19 (OR: 3.0; 95% CI: 1.9-4.9).

Project description:Risk factors for severe SARS-Cov-2 infection course are poorly described in children following hematopoietic cell transplantation (HCT). In this international study, we analyzed factors associated with a severe course (intensive care unit (ICU) admission and/or mortality) in post-HCT children. Eighty-nine children (58% male; median age 9 years (min-max 1-18)) who received an allogeneic (85; 96%) or an autologous (4; 4%) HCT were reported from 28 centers (18 countries). Median time from HCT to SARS-Cov-2 infection was 7 months (min-max 0-181). The most common clinical manifestations included fever (37; 42%) and cough (26; 29%); 37 (42%) were asymptomatic. Nine (10%) children following allo-HCT required ICU care. Seven children (8%) following allo-HCT, died at a median of 22 days after SARS-Cov-2 diagnosis. In a univariate analysis, the probability of a severe disease course was higher in allo-HCT children with chronic GVHD, non-malignant disease, immune suppressive treatment (specifically, mycophenolate), moderate immunodeficiency score, low Lansky score, fever, cough, coinfection, pulmonary radiological findings, and high C-reactive protein. In conclusion, SARS-Cov-2 infection in children following HCT was frequently asymptomatic. Despite this, 10% needed ICU admission and 8% died in our cohort. Certain HCT, underlying disease, and SARS-Cov-2 related factors were associated with a severe disease course.

Project description:This study reports on 382 COVID-19 patients having undergone allogeneic (n = 236) or autologous (n = 146) hematopoietic cell transplantation (HCT) reported to the European Society for Blood and Marrow Transplantation (EBMT) or to the Spanish Group of Hematopoietic Stem Cell Transplantation (GETH). The median age was 54.1 years (1.0-80.3) for allogeneic, and 60.6 years (7.7-81.6) for autologous HCT patients. The median time from HCT to COVID-19 was 15.8 months (0.2-292.7) in allogeneic and 24.6 months (-0.9 to 350.3) in autologous recipients. 83.5% developed lower respiratory tract disease and 22.5% were admitted to an ICU. Overall survival at 6 weeks from diagnosis was 77.9% and 72.1% in allogeneic and autologous recipients, respectively. Children had a survival of 93.4%. In multivariate analysis, older age (p = 0.02), need for ICU (p < 0.0001) and moderate/high immunodeficiency index (p = 0.04) increased the risk while better performance status (p = 0.001) decreased the risk for mortality. Other factors such as underlying diagnosis, time from HCT, GVHD, or ongoing immunosuppression did not significantly impact overall survival. We conclude that HCT patients are at high risk of developing LRTD, require admission to ICU, and have increased mortality in COVID-19.

Project description:Hematopoietic stem cell transplantation (HSCT) is widely used in pediatric patients as a successful curative therapy for life-threatening conditions. The treatment is intensive, with risks of serious complications and lethal outcomes. This study aimed to provide insight into current data on the place and cause of death of transplanted children, the available specialized pediatric palliative care services (SPPCS), and what services HSCT professionals feel the SPPCS team should provide. First, a retrospective database analysis on the place and cause of death of transplanted pediatric HSCT patients was performed. Second, a survey was performed addressing the availability of and views on SPPCS among HSCT professionals. Database analysis included 233 patients of whom the majority died in-hospital: 38% in the pediatric intensive care unit, 20% in HSCT units, 17% in other hospitals, and 14% at home or in a hospice (11% unknown). For the survey, 98 HSCT professionals from 54 centers participated. Nearly all professionals indicated that HSCT patients should have access to SPPCS, especially for pain management, but less than half routinely referred to this service at an early stage. We, therefore, advise HSCT teams to integrate advance care planning for pediatric HSCT patients actively, ideally from diagnosis, to ensure timely SPPCS involvement and maximize end-of-life preparation.

Project description:To identify factors associated with parent activation in parents of children undergoing pediatric hematopoietic stem cell transplant (HSCT) in the 6 months following HSCT, and to address if their association with parent activation changes over time.Measures for this analysis, including the Parent-Patient Activation Measure (Parent-PAM), were completed by parents (N?=?198) prior to their child's HSCT preparative regimen and again at 6 months post-HSCT. Clinical data were also collected. A repeated measures model was built to estimate the association between clinical and demographic factors and parent well-being on Parent-PAM scores. Interactions with time were considered to test for changing effects over time.Throughout the HSCT course, older parent age was associated with lower Parent-PAM scores (??=?-0.29, p?=?0.02) and never being married was associated with higher scores (versus married, ??=?12.27, p?=?0.03). While higher parent emotional functioning scores were not associated with activation at baseline, they were important at 6 months (baseline, ??=?-0.002, p?=?0.96; interaction, ??=?0.14, p?=?0.03). At baseline, longer duration of illness was associated with increased activation, but this effect diminished with time (baseline, ??=?3.29, p?=?0.0002; interaction, ??=?-2.40, p?=?0.02). Activation levels dropped for parents of children who went from private to public insurance (baseline, ??=?2.95, p?=?0.53; interaction, ??=?-13.82, p?=?0.004). Clinical events did not affect Parent-PAM scores.Our findings reveal important changes in the factors associated with parent activation in the first 6 months after pediatric HSCT. These findings may reflect the emotional and financial toll of pediatric HSCT on parent activation.
