Effectiveness of Bath Wipes After Hematopoietic Cell Transplantation: A Randomized Trial.

ABSTRACT: Objective: Bacteremia is a leading cause of morbidity and mortality in children undergoing hematopoietic cell transplantation (HCT). Infections of vancomycin-resistant enterococci (VRE) and multidrug resistant (MDR) gram-negative rods (GNRs) are common in this population. Our objective was to assess whether experimental bath wipes containing silver were more effective than standard bath wipes containing soap at reducing skin colonization by VRE and MDR GNRs, and nonmucosal barrier injury bacteremia. Study Design: Patients undergoing autologous or allogeneic HCT in a tertiary referral center were randomized to receive experimental or standard bath wipes for 60 days post-HCT. Skin swabs were collected at baseline, discharge, and day +60 post-HCT. The rate of VRE colonization was chosen as the marker for efficacy. Results: Experimental bath wipes were well tolerated. Before the study, the rate of colonization with VRE in HCT recipients was 25%. In an interim analysis of 127 children, one (2%) patient in the experimental arm and two (3%) in the standard arm were colonized with VRE. Two (3%) patients had nonmucosal barrier injury bacteremia in the standard arm, with none in the experimental arm. MDR GNRs were not isolated. The trial was halted because the interim analyses indicated equivalent efficacy of the two methods. Conclusions: Skin cleansing with silver-containing or standard bath wipes resulted in very low and equivalent rates of bacteremia and colonization with VRE and MDR GNRs in children post-HCT. Future studies in other high-risk populations are needed to confirm these results.

Project description:BackgroundCaregivers of patients undergoing hematopoietic stem cell transplantation (HCT) experience an immense caregiving burden before, during, and after HCT.MethodsWe conducted an unblinded, randomized trial of a psychosocial intervention (BMT-CARE) for caregivers of patients undergoing autologous and allogeneic HCT at Massachusetts General Hospital. Caregivers were randomly assigned to BMT-CARE or usual care. BMT-CARE was tailored to the HCT trajectory and integrated treatment-related education and self-care with cognitive-behavioral skills to promote coping. Caregivers assigned to BMT-CARE met with a trained interventionist (a psychologist or a social worker) in person, via telephone, or via videoconferencing for 6 sessions starting before HCT and continuing up to day +60 after HCT. The primary endpoint was feasibility, which was defined as at least 60% of eligible caregivers enrolling and completing 50% or more of the intervention sessions. We assesed caregiver quality of life (QOL; Caregiver Oncology Quality of Life Questionnaire), caregiving burden (Caregiver Reaction Assessment), psychological distress (Hospital Anxiety and Depression Scale), self-efficacy (Cancer Self-Efficacy Scale-Transplant), and coping (Measures of Current Status) at baseline and 30 and 60 days after HCT. We used mixed linear effect models to assess the effect of BMT-CARE on outcomes longitudinally.ResultsWe enrolled 72.5% of eligible caregivers (100 of 138), and 80% attended 50% or more of the intervention sessions. Caregivers randomized to BMT-CARE reported improved QOL (B = 6.11; 95% CI, 3.50-8.71; P < .001), reduced caregiving burden (B = -6.02; 95% CI, -8.49 to -3.55; P < .001), lower anxiety (B = -2.18; 95% CI, -3.07 to -1.28; P < .001) and depression symptoms (B = -1.23; 95% CI, -1.92 to -0.54; P < .001), and improved self-efficacy (B = 7.22; 95% CI, 2.40-12.03; P = .003) and coping skills (B = 4.83; 95% CI, 3.04-6.94; P < .001) in comparison with the usual-care group.ConclusionsA brief multimodal psychosocial intervention tailored for caregivers of HCT recipients is feasible and may improve QOL, mood, coping, and self-efficacy while reducing the caregiving burden during the acute HCT period.

Project description:BackgroundInsight regarding transfusion practices in Hematopoietic Stem cell Transplantation (HSCT) are lacking and the impact of red cell transfusion in this high risk group on outcomes following HSCT are not well appreciated. Red blood cell transfusion can be life-saving, however, liberal use of transfusion in critically ill patients failed to demonstrate significant clinical benefit. A large number of other observational studies have also demonstrated an association between red blood cell transfusions and increased morbidity such as infections and multi organ failure as well as increased mortality. The role of red cell transfusion on the clinical outcomes observed in patients undergoing HSCT remains poorly understood and a prospective randomized study of transfusion is required to gain insight and knowledge on best transfusion practices in this high risk population.MethodsThis report describes the design and methodological issues of a randomized pilot study evaluating red cell transfusion triggers in the setting of Hematopoietic Stem Cell Transplantation. This study has been funded by a peer review grant from the Canadian Blood Services and is registered on Clinicaltrials.gov NCT01237639.ResultsIn 3 Canadian centres, 100 patients undergoing Hematopoietic Stem Cell Transplantation will be randomized to either a restrictive (target hemoglobin of 70-90 g/L) or liberal (target hemoglobin of 90-110 g/L) red cell transfusion strategy, based daily hemoglobin values up to 100 days post-transplant. The study will stratify participants by centre and type of transplant. The primary goal is to demonstrate study feasibility and we will collect clinical outcomes on 1) Transfusion Requirements, 2) Transplant Related Mortality, 3) Maximum grade of acute Graft versus Host Disease, 4) Veno-occlusive Disease, 5) Serious Infections, 6) Bearman Toxicity Score, 7) Bleeding, 8) Quality of Life, 9) Number of Hospitalizations and 10) Number of Intensive Care Unit (ICU) Admissions.ConclusionUpon completion, this pilot trial will provide preliminary insight into red cell transfusion practice and its influence in hematopoietic stem cell transplant outcomes. The results of this trial will inform the conduct of a larger study.

Project description:BackgroundOptimal prevention of late cytomegalovirus (CMV) disease is poorly defined.ObjectiveTo compare valganciclovir prophylaxis with polymerase chain reaction-guided preemptive therapy.DesignRandomized, double-blind trial. (ClinicalTrials.gov: NCT00016068).SettingMulticenter trial.Patients184 recipients of hematopoietic cell transplantation (HCT) who were at high risk for late CMV disease (95 patients received valganciclovir and 89 received placebo).Intervention6 months of valganciclovir (900 mg/d) or placebo. Patients with polymerase chain reaction positivity at 1000 copies/mL or greater or a 5-fold increase over baseline were treated with ganciclovir or valganciclovir (5 mg/kg or 900 mg twice daily, respectively).MeasurementsThe composite primary end point was death, CMV disease, or other invasive infections by 270 days after HCT. Secondary end points were CMV disease, CMV DNAemia, death, other infections, resource utilization, ganciclovir resistance, quality of life, immune reconstitution, and safety.ResultsThe primary composite outcome occurred in 20% of valganciclovir recipients versus 21% of placebo-preemptive therapy recipients (treatment difference, -0.01 [95% CI, -0.13 to 0.10]; P = 0.86). There was no difference in the primary end point or its components 640 days after HCT. The incidence of a CMV DNAemia level of 1000 copies/mL or greater or a 5-fold increase over baseline was reduced in the valganciclovir group (11% vs. 36%; P < 0.001). Neutropenia was not significantly different at the absolute neutrophil count of less than 0.5 × 109 cells/L (P = 0.57); however, more patients received hematopoietic growth factors in the valganciclovir group (25.3% vs. 12.4%; P = 0.026). No significant differences were seen in other secondary outcomes.LimitationSome high-risk patients were not included.ConclusionValganciclovir prophylaxis was not superior in reducing the composite end point of CMV disease, invasive bacterial or fungal disease, or death when compared with polymerase chain reaction-guided preemptive therapy. Both strategies performed similarly with regard to most clinical outcomes.Primary funding sourceRoche Laboratories.

Project description:Autologous hematopoietic stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). However, up to 30% of MM patients are unable to collect optimal numbers of peripheral blood (PB) CD34+ hematopoietic stem and progenitor cells (HSPCs) with standard G-CSF mobilization. Motixafortide is a novel cyclic-peptide CXCR4 inhibitor with extended receptor occupancy and enhanced in-vivo activity. The GENESIS Trial is a prospective, phase III, double-blind, placebo-controlled, international, multicenter, superiority trial with 122 adult patients randomized (2:1) to motixafortide+G-CSF or placebo+G-CSF for HSPC mobilization for ASCT in MM (NCT03246529). The primary endpoint of the study was met, with motixafortide+G-CSF enabling 92.5% of patients to collect ≥6x106 CD34+ cells/kg within 2 apheresis procedures versus 26.2% with placebo+G-CSF (p<0.0001). A key, prespecified secondary endpoint was also met, with motixafortide+G-CSF enabling 88.8% of patients to collect ≥6x106 CD34+ cells/kg in 1 apheresis versus 9.5% with placebo+G-CSF (p<0.0001). Motixafortide+G-CSF was safe and well-tolerated, with the most common treatment-emergent adverse events observed being transient, Grade 1/2 injection site reactions (pain: 50%, erythema: 27.5%, pruritis: 21.3%). In addition, extended immunophenotyping and single-cell transcriptional profiling were performed on CD34+ HSPCs mobilized on the GENESIS Trial, as well as a contemporaneous MM cohort undergoing plerixafor+G-CSF mobilization for ASCT and 3 cohorts of allogeneic HSPC donors undergoing single-agent mobilization with motixafortide, plerixafor or G-CSF alone. Motixafortide+G-CSF resulted in a 10.5-fold increase in primitive HSPCs collected versus placebo+G-CSF (p<0.0001); and significantly greater numbers of early stem and progenitors versus both placebo+G-CSF (p<0.0001) and plerixafor+G-CSF (p=0.0327). Motixafortide also preferentially mobilized HSPC subsets with upregulated gene expression pathways associated with enhanced self-renewal, regeneration and quiescence (EGF, NFB/TNF and HBO1). In conclusion, motixafortide+G-CSF mobilized significantly greater CD34+ HSPC numbers within 2 apheresis procedures versus placebo+G-CSF. Motixafortide also preferentially mobilized primitive stem and early progenitor cells with unique transcriptional profiles versus plerixafor and G-CSF.
