Abstract

PURPOSE: We investigated the prevalence of financial toxicity in a population undergoing hematopoietic cell transplantation (HCT) evaluation and measured its impact on post-transplant clinical and health-related quality-of-life outcomes. MATERIALS AND METHODS: This was a prospective study in patients undergoing evaluation for allogeneic HCT between January 1, 2018, and September 23, 2020, at a large academic medical center. Financial health was measured via a baseline survey and the comprehensive score for financial toxicity-functional assessment of chronic illness therapy (COST-FACIT) survey. The cohort was divided into three groups: none (grade 0), mild (grade 1), and moderate-high financial toxicity (grades 2-3). Health-related quality of life outcomes were measured at multiple time points. Multivariate logistic regression analysis evaluated factors associated with financial toxicity. Kaplan-Meier curves and log-rank tests was used to evaluate overall survival (OS) and nonrelapse survival. RESULTS: Of 245 patients evaluated for transplant, 176 (71.8%) completed both questionnaires (median age was 57 years, 63.1% were male, 72.2% were White, and 39.2% had myelodysplastic syndrome, 38.1% leukemia, and 13.6% lymphoma). At initial evaluation, 83 (47.2%) patients reported no financial toxicity, 51 (29.0%) with mild, and 42 (23.9%) with moderate-high financial toxicity. Patients with financial toxicity reported significant cost-cutting behaviors, including reduced spending on food or clothing, using their savings, or not filling a prescription because of costs (P <.0001). Quality of life was lower in patients with moderate-high financial toxicity at 6 months (P =.0007) and 1 year (P =.0075) after transplant. Older age (>62; odds ratio [OR], 0.33 [95% CI, 0.13 to 0.79]; P =.04) and income ≥$60,000 in US dollars (USD) (OR, 0.17 [95% CI, 0.08 to 0.38]; P <.0001) were associated with lower odds of financial toxicity. No association was noted between financial toxicity and selection for transplant, OS, or nonrelapse mortality. CONCLUSION: Financial toxicity was highly correlated with patient-reported changes in compensatory behavior, with notable impact on patient quality of life after transplant. Prospective cohort study demonstrates a major impact of #FinancialToxicity in driving cost-cutting behaviors and worse quality of life in patients undergoing bone marrow transplant [ABSTRACT FROM AUTHOR]

Abstract

Background Enterococcus intestinal domination (EID), a state of dysbiosis wherein enterococci comprise ≥30% abundance within the microbiota, has been associated with Enterococcus bacteremia, graft-versus-host disease, and mortality in the allogeneic hematopoietic stem cell transplant (allo HCT) population. The acute leukemia (AL) chemotherapy population includes patients receiving intensive chemotherapy, but not all patients go on to have an allo HCT. The impact of EID on outcomes including mortality in the AL chemotherapy population is unknown. Methods Microbiota composition from weekly stool samples was analyzed using 16S ribosomal RNA gene sequencing. Patients were analyzed in 2 cohorts: AL chemotherapy cohort and allo HCT cohort. α -diversity and richness were calculated. Kaplan-Meier analysis was used to analyze mortality. Results A total of 929 stool samples were collected from 139 patients. Both allo HCT and AL cohorts had a decline in α-diversity and richness over the course of treatment that tended not to return to baseline months later. EID was observed in at least 1 sample in 36% of allo HCT patients and 49% of AL patients. Patients with observed EID had lower α-diversity over time. Similar to the HCT cohort, AL patients with EID had reduced overall survival. We identified 4 other genera that were commonly found in ≥30% relative abundance within the microbiota, but none were associated with mortality. In fact, in allo HCT, Bacteroides abundance ≥30% was associated with improved survival. Conclusions EID is associated with increased all-cause mortality in HCT and AL cohorts. Unlike EID, relative abundance ≥30% by other genera is not associated with increased all-cause mortality. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Although allogeneic hematopoietic stem cell transplantation (HCT) can be a curative therapy for hematologic disorders, it is associated with treatment-related complications and losses in cardiorespiratory fitness and physical function. High-intensity interval training (HIIT) may be a practical way to rapidly improve cardiorespiratory fitness and physical function in the weeks prior to HCT. The primary aim of this study was to assess the feasibility of implementing a pre-HCT home-based HIIT intervention. The secondary aim was to evaluate pre to post changes in cardiorespiratory fitness and physical function following the intervention. Methods: This was a single-arm pilot study with patients who were scheduled to undergo allogeneic HCT within six months. Patients were instructed to complete three 30-minute home-based HIIT sessions/week between the time of study enrollment and sign-off for HCT. Sessions consisted of a 5-minute warm-up, 10 high and low intervals performed for one minute each, and a 5-minute cool-down. Prescribed target heart rates (HR) for the high- and low-intensity intervals were 80–90% and 50–60% of HR reserve, respectively. Heart rates during HIIT were captured via an Apple Watch and were remotely monitored. Feasibility was assessed via retention, session adherence, and adherence to prescribed interval number and intensities. Paired t-tests were used to compare changes in fitness (VO2peak) and physical function [Short Physical Performance Battery (SPPB), 30-second sit to stand, and six-minute walk test (6MWT)] between baseline and sign-off. Pearson correlations were used to determine the relationship between intervention length and changes in cardiorespiratory fitness or functional measures. Results: Thirteen patients (58.8±11.6 years) participated in the study, and nine (69.2%) recorded their training sessions throughout the study. Median session adherence for those nine participants was 100% (IQR: 87–107). Adherence to intervals was 92% and participants met or exceeded prescribed high-intensity HR on 68.8±34.8% of intervals. VO2peak improved from baseline to sign-off (14.6±3.1 mL/kg/min to 17.9±3.3 mL/kg/min; p<0.001). 30-second sit to stand and SPPB chair stand scores significantly improved in adherent participants. Improvements in 30-second sit to stand (13.8±1.5 to 18.3±3.3 seconds) and 6MWT (514.4±43.2 to 564.6±19.3) exceeded minimal clinically important improvements established in other chronic disease populations, representing the minimum improvement considered meaningful to patients. Conclusions: Findings demonstrate that implementing a pre-HCT home-based remotely monitored HIIT program is feasible and may provide benefits to cardiorespiratory fitness and physical function.

Abstract

The gut microbiota influences the development and homeostasis of the mammalian immune system 1–3 , can alter immune cell compositions in mice 4–7 , and is associated with responses to immunotherapy that rely on the activity of peripheral immune cells 8–12 . Still, our understanding of how the microbiota modulates circulatory immune cells remains limited, particularly in humans where a lack of manipulative experiments makes inference challenging. Here we overcome this challenge by studying hundreds of hospitalized—and closely monitored—bone marrow transplantation patients as they recover from chemotherapy-induced immune ablation. This aggressive treatment causes large shifts in both circulatory immune cell and microbiota populations, allowing the relationships between the two to be studied simultaneously over time with unprecedented resolution. We analyzed daily changes in white blood cell counts from 2,235 patients, and 10,680 longitudinal fecal microbiota samples to identify bacterial genera consistently associated with those changes. Bayesian inference and validation across different patient cohorts revealed consistent associations between intestinal bacteria and peripheral immune cell dynamics in the context of immunomodulatory medications, clinical metadata and homeostatic feedbacks between peripheral immune cells. The quantification of validated microbiota associations enabled us to contrast the potency of fermentatively active, obligate anaerobic bacteria with that of medications with known immunomodulatory mechanism, and this way estimate the microbiota potential to alter peripheral immune cell dynamics directly in patients. Our analysis establishes and quantifies the link between the intestinal microbiota and immune cell dynamics in humans, with implications for microbiota-driven modulation of immunity and immunotherapies that rely on circulatory immune cells.
