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:BackgroundIn a recent trial, a 6-session intervention (BMT-CARE) integrating medical information with cognitive-behavioral strategies improved quality of life (QOL), mood, coping skills, and self-efficacy for family/friend caregivers of hematopoietic stem cell transplantation (HCT) recipients. This study examined whether improvements in coping and self-efficacy mediated the intervention effects on QOL and mood.MethodsFrom December 2017 to April 2019, 100 caregivers of HCT recipients were enrolled into a randomized clinical trial of BMT-CARE versus usual care. Caregivers completed self-report measures of QOL (CareGiver Oncology Quality of Life questionnaire), depression and anxiety symptoms (Hospital Anxiety and Depression Scale), coping skills (Measure of Current Status), and self-efficacy (Cancer Self-Efficacy Scale-Transplant) at enrollment (before HCT) and 60 days after HCT. Causal mediation regression models were used to examine whether changes in coping and self-efficacy mediated intervention effects on QOL as well as depression and anxiety symptoms.ResultsImprovements in 60-day QOL in patients assigned to BMT-CARE were partially mediated by improved coping and self-efficacy (indirect effect, 6.93; SE, 1.85; 95% CI, 3.71-11.05). Similarly, reductions in 60-day depression and anxiety symptoms were partially mediated by improved coping and self-efficacy (indirect effect for depression, -1.19; SE, 0.42; 95% CI, -2.23 to -0.53; indirect effect for anxiety, -1.46; SE, 0.55; 95% CI, -2.52 to -0.43). Combined improvements in coping and self-efficacy accounted for 67%, 80%, and 39% of the total intervention effects on QOL and depression and anxiety symptoms, respectively.ConclusionsCoping and self-efficacy are essential components of a brief psychosocial intervention that improves QOL and mood for caregivers of HCT recipients during the acute recovery period.Lay summaryA 6-session program (BMT-CARE) focused on providing medical information, caregiving skills, and self-care and coping strategies has been previously reported to improve the quality of life and mood of caregivers of hematopoietic stem cell transplantation recipients in comparison with caregivers who receive care as usual. Using statistical models, this study suggests that learning coping skills and improving self-efficacy are the most essential components of this program that likely lead to better quality of life and mood for caregivers.

Project description:Bronchiolitis obliterans syndrome has been associated with increased morbidity and mortality after allogeneic hematopoietic stem cell transplant (HSCT). Previous studies have suggested that azithromycin may reduce the incidence of post-lung transplant bronchiolitis obliterans syndrome.To evaluate if the early administration of azithromycin can improve airflow decline-free survival after allogeneic HSCT.The ALLOZITHRO parallel-group trial conducted in 19 French academic transplant centers and involving participants who were at least 16 years old, had undergone allogeneic HSCT for a hematological malignancy, and had available pretransplant pulmonary function test results. Enrollment was from February 2014 to August 2015 with follow-up through April 26, 2017.Patients were randomly assigned to receive 3 times a week either 250 mg of azithromycin (n?=?243) or placebo (n?=?237) for 2 years, starting at the time of the conditioning regimen.The primary efficacy end point was airflow decline-free survival at 2 years after randomization. Main secondary end points were overall survival and bronchiolitis obliterans syndrome at 2 years.Thirteen months after enrollment, the independent data and safety monitoring board detected an unanticipated imbalance across blinded groups in the number of hematological relapses, and the treatment was stopped December 26, 2016. Among 480 randomized participants, 465 (97%) were included in the modified intention-to-treat analysis (mean age, 52 [SD, 14] years; 75 women [35%]). At the time of data cutoff, 104 patients (22%; 54 azithromycin vs 50 placebo) had experienced an airflow decline; 138 patients (30%) died (78 azithromycin vs 60 placebo). Two-year airflow decline-free survival was 32.8% (95% CI, 25.9%-41.7%) with azithromycin and 41.3% (95% CI, 34.1%-50.1%) with placebo (unadjusted hazard ratio [HR], 1.3; 95% CI, 1.02-1.70; P?=?.03). Of the 22 patients (5%) who experienced bronchiolitis obliterans syndrome, 15 (6%) were in the azithromycin group and 7 (3%) in the placebo group (P?=?.08). The azithromycin group had increased mortality, with a 2-year survival of 56.6% (95% CI, 50.2%-63.7%) vs 70.1% (95% CI, 64.2%-76.5%) in the placebo group (unadjusted HR, 1.5; 95% CI, 1.1-2.0; P?=?.02). In a post hoc analysis, the 2-year cumulative incidence of hematological relapse was 33.5% (95% CI, 27.3%-39.7%) with azithromycin vs 22.3% (95% CI, 16.4%-28.2%) with placebo (unadjusted cause-specific HR, 1.7; 95% CI, 1.2-2.4; P?=?.002).Among patients undergoing allogeneic HSCT for hematological malignancy, early administration of azithromycin resulted in worse airflow decline-free survival than did placebo; these findings are limited by early trial termination. The potential for harm related to relapse requires further investigation.clinicaltrials.gov Identifier: NCT01959100.
