Physical function and quality of life in patients with chronic GvHD: a summary of preclinical and clinical studies and a call for exercise intervention trials in patients

The impact of acute and chronic aerobic and resistance exercise on stem cell mobilization: A review of effects in healthy and diseased individuals across different age groups

Stem cells (SCs) play a crucial role in tissue repair, regeneration, and maintaining physiological homeostasis. Exercise mobilizes and enhances the function of SCs. This review examines the effects of acute and chronic aerobic and resistance exercise on the population of SCs in healthy and diseased individuals across different age groups. Both acute intense exercise and moderate regular training increase circulating precursor cells CD34+ and, in particular, the subset of angiogenic progenitor cells (APCs) CD34+/KDR+. Conversely, chronic exercise training has conflicting effects on circulating CD34+ cells and their function, which are likely influenced by exercise dosage, the health status of the participants, and the methodologies employed. While acute activity promotes transient mobilization, regular exercise often leads to an increased number of progenitors and more sustainable functionality. Short interventions lasting 10-21 days mobilize CD34+/KDR + APCs in sedentary elderly individuals, indicating the inherent capacity of the body to rapidly activate tissue-reparative SCs during activity. However, further investigation is needed to determine the optimal exercise regimens for enhancing SC mobilization, elucidating the underlying mechanisms, and establishing functional benefits for health and disease prevention. Current evidence supports the integration of intense exercise with chronic training in exercise protocols aimed at activating the inherent regenerative potential through SC mobilization. The physical activity promotes endogenous repair processes, and research on exercise protocols that effectively mobilize SCs can provide innovative guidelines designed for lifelong tissue regeneration. An artificial neural network (ANN) was developed to estimate the effects of modifying elderly individuals and implementing chronic resistance exercise on stem cell mobilization and its impact on individuals and exercise. The network's predictions were validated using linear regression and found to be acceptable compared to experimental results.

Immunosuppression-Free Status at 1 Year after Haploidentical Hematopoietic Cell Transplantation with Post-Transplantation Cyclophosphamide

The development of chronic graft-versus-host disease (GVHD) in 1-year survivors after matched related or unrelated hematopoietic cell transplantation was shown to be associated with higher nonrelapse mortality (NRM) and worse overall survival (OS). The impact of chronic GVHD requiring immunosuppression (IS) for recipients of haploidentical transplantation (HIDT) with post-transplantation cyclophosphamide (PTCy) who have survived to 1 year post-transplantation has not been studied previously and was investigated for this analysis. A total of 322 adult patients who underwent HIDT at our center were included in this study. The effect of IS-free status on post-transplantation outcomes was assessed. The median follow-up for survivors was 63.9 months (range, 18.3 to 165 months). A total of 163 patients (65%) were IS-free at 1 year post-HIDT. Baseline characteristics of this group were similar to those of patients still requiring IS, except for higher percentages of female donor-male recipient pairs (28% versus 15%; P =.03) and female donors (48% versus 30%; P =.008). Logistic regression to identify patients more likely to be on IS at 1 year post-HIDT identified the use of a female donor as a significant risk factor (odds ratio, 2.11; P = .009). In a Cox regression analysis, patients requiring IS at 1 year post-transplantation had higher NRM (hazard ratio [HR], 4.18; 95% confidence interval [CI], 1.80 to 6.72; P < .001) and showed a trend toward worse disease-free survival (DFS) (HR, 1.59; 95% CI, .95 to 2.66; P =.08), with no impact on OS (HR, 1.44; 95% CI, .90 to 2.31; P = .13) or relapse (HR, .77; 95% CI, .37 to 1.61; P = .49). These results indicate that use of a female donor is a significant risk factor for requiring IS at 1 year post-HIDT. Additionally, chronic GVHD requiring IS at 1-year post-HIDT no significant effect on relapse but is associated with higher NRM and a trend toward worse DFS.

Prehabilitative high-intensity interval training and resistance exercise in patients prior allogeneic stem cell transplantation

Physical capacity prior allogeneic stem cell transplantation (allo-HCT) has been shown as a relevant prognostic factor for survival after transplant. Therefore, we evaluated feasibility and preliminary efficacy of a high-intensity interval training (HIIT) and moderate to high-intensity resistance exercise (RE) to increase physical capacity in patient's prior allo-HCT. In this multicentre single arm pilot study, a supervised exercise program was performed twice weekly for 4-12 weeks prior allo-HCT, depending on the individual time remaining. Outcomes were feasibility (recruitment, adherence, safety), physical capacity (cardiorespiratory fitness [VO2peak], muscle strength) and patient reported outcomes (physical functioning, fatigue). Thirty patients were intended, 16 could be included, and 14 completed post intervention assessment (75% male, 55 ± 11 years). The study was stopped early due to a low recruitment rate. Nine patients (64%) reached the initial minimum planned number of eight exercise sessions. Individual adherence was high with 92% for HIIT and 85% for RE. 87% of all performed exercise sessions were completed without complaints and VO2peak increased significantly from 20.4 to 23.4 ml/kg/min. The low recruitment rate suggests that initiation of the intervention concept immediately before allo-HCT is feasible only in a small number of patients. In particular, the timeframe directly prior allo-HCT seems too short for exercise interventions, although the exercise program was designed to improve outcomes in a very short time frame. HIIT and RE were feasible, effective and well accepted by the included patients.

Reciprocal associations between beliefs about medicines, health locus of control and adherence to immunosuppressive medication in allogeneic hematopoietic cell transplant patients: Findings from the ADE-TRAM study

PURPOSE

Patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT) are required to strictly adhere to immunosuppressive medications to avoid rejection and infective complications. Since medication adherence is among the most important modifiable behaviors to achieve better outcomes, the aims of this study were to measure the baseline and longitudinal trends of medication adherence and investigate the psychological factors associated with medication adherence in allo-HSCT patients.

METHODS

This was a single-center, longitudinal study of patients who underwent allo-HSCT to treat hematological malignancies at the University hospital of Florence (Italy). Adherence was measured with the Immunosuppressive Medication Self-Management Scale; psychological factors (i.e., beliefs about medicines and health locus of control) were measured with the Beliefs About Medicines Questionnaire and Multidimensional Health locus of Control Scale. Data were collected 1, 3, 6 and 12 months after discharge. A mixed effects model was performed after adjusting for demographic characteristics.

RESULTS

50 adult patients were included in this study. Adherence to immunosuppressant was optimal and increased significantly 3 months after bone marrow transplantation (B = 0.23, p = 0.041). Patients with lower concerns about immunosuppressive medications were more likely to be adherent (B = 0.02, p = 0.040), while those having beliefs that their disease was due to external factors were less likely to be adherent (B = -0.02, p = 0.026) than their counterparts.

CONCLUSIONS

These results underline the importance of psychological factors in affecting adherence to immunosuppressants of allo-HSCT patients. Healthcare providers and researchers should target medication beliefs and reorient locus of control with appropriate interventions, in order to improve adherence.

Unrelated female-to-male bone marrow transplantation would be preferred over cord blood transplantation in male patients

BACKGROUND AIMS

Allogeneic hematopoietic stem cell transplantation from female donors to male recipients (female-to-male allo-HCT) is a well-established risk factor for a greater incidence of non-relapse mortality (NRM) and chronic graft-versus-host disease (GVHD). In contrast, unrelated cord blood transplantation (UCBT) is associated with a lower incidence of chronic GVHD. In this study, survival outcomes were compared between the UCBT and unrelated female-to-male bone marrow transplantation (UFMBMT) groups.

METHODS

We evaluated male allo-HCT recipients who underwent UCBT or UFMBMT between 2012 and 2020 in Japan. There were 2517 cases in the UCBT group, 456 cases in the HLA-matched UFMBMT group and 457 cases in the HLA-mismatched UFMBMT group.

RESULTS

HLA-mismatched UFMBMT was significantly associated with a decreased risk of relapse (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.57-0.98], P = 0.033) and HLA-matched UFMBMT had the tendency of a decreased risk of relapse (HR 0.78; 95% CI 0.61-1.01, P = 0.059). HLA-matched UFMBMT was also associated with favorable OS (HR 0.82; 95% CI 0.69-0.97, P = 0.021). The relationship between the donor sources and relapse was similarly observed in the lymphoid malignancy cohort.

CONCLUSIONS

The difference of graft-versus leukemia effect by H-Y immunity according to donor sources might contribute to the difference in clinical impact. It might be desirable for patients who could sufficiently wait for donor coordination to select BMT rather than UCBT, even if only unrelated female donors are available for male recipients.

Psychological states and needs among post-allogeneic hematopoietic stem cell transplantation survivors

OBJECTIVES

To analyze psychological states and needs of patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS

Questionnaires were sent to 101 allo-HSCT survivors and 96 questionnaires were returned. The questionnaire covered several categories: (1) demographics and general information, (2) physical conditions, (3) psychologic status and sleep quality, (4) survivor's comments on transplantation, (5) demands and needs, (6) preferred forms and channels of information.

RESULTS

Depression and poor sleep quality were major concerns troubling allo-HSCT survivors. A notable discrepancy exists between clinically diagnosed depression (4.2%) and self- reported depression based on BDI-13 (55.2%). Young adults (18-49 years old), chronic graft-versus-host disease, the ECOG performance score of 2-4, surviving within 5 years since HSCT, no or low dose of ATG used and being single were significantly associated with self-reported depression. Based on the PSQI score, 75% of survivors experienced varying degrees of sleep quality impairment. Young adults, chronic GVHD and the ECOG score of 2-4 were significantly associated with worse sleep quality. The majority of patients reported unmet needs on physical and psychosocial aspects. Nutrition information was the most important topic, followed by disease treatments and fatigue. Differences in informational needs were found in the survivors according to age, time since HSCT and gender. WeChat public account and WeChat applet, mobile interactive platform and one-to-one conversation were the favorite channel for information.

CONCLUSIONS

Clinicians should establish more appropriate survivorship care plans focusing on survivors' psychologic states, demands and needs.

Influence of SPIO labelling on the function of BMSCs in chemokine receptors expression and chemotaxis

Bone marrow-derived mesenchymal stem cells (BMSCs) are increasingly being used in bone marrow transplantation (BMT) to enable homing of the allogeneic hematopoietic stem cells and suppress acute graft versus host disease (aGVHD). The aim of this study was to optimize the labelling of BMSCs with superparamagnetic iron oxide particles (SPIOs), and evaluate the impact of the SPIOs on the biological characteristics, gene expression profile and chemotaxis function of the BMSCs. The viability and proliferation rates of the SPIO-labeled BMSCs were analyzed by trypan blue staining and CCK-8 assay respectively, and the chemotaxis function was evaluated by the transwell assay. The expression levels of chemokine receptors were measured by RT-PCR and flow cytometry. The SPIOs had no effect on the viability of the BMSCs regardless of the labelling concentration and culture duration. The labelling rate of the cells was higher when cultured for 48 h with the SPIOs. Furthermore, cells labeled with 25 µg/ml SPIOs for 48 h had the highest proliferation rates, along with increased expression of chemokine receptor genes and proteins. However, there was no significant difference between the chemotaxis function of the labeled and unlabeled BMSCs. To summarize, labelling BMSCs with 25 µg/ml SPIOs for 48h did not affect their biological characteristics and chemotaxis function, which can be of significance for in vivo applications.

Impact of Chronic Graft-Versus-Host Disease (GVHD) on Patients' Employment, Income, and Informal Caregiver Burden: Findings From the Living With Chronic GVHD Patient Survey

BACKGROUND

Development of chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT) results in impaired physical function and quality of life. However, limited data exist regarding the employment and financial impact on patients and caregivers.

OBJECTIVE

The objective of this study was to describe the impact of chronic GVHD on patient employment, disability leave, income, reliance on caregivers, and effects on caregiver employment.

STUDY DESIGN

The Living With Chronic GVHD Patient Survey was a cross-sectional online survey administered from May to August 2020 in the United States to adult HSCT survivors diagnosed with chronic GVHD within the past 5 years. Data on respondent demographics and disease characteristics and the effects of chronic GVHD on employment, income, and need for caregiver assistance were collected. Respondents were also asked to report on the impact of their chronic GVHD on their caregivers' employment. All data were summarized using descriptive statistics; no formal statistical comparisons were conducted.

RESULTS

A total of 165 respondents completed the survey (median age, 57.0 years; 63.6% women; 83.0% White); respondents had been experiencing chronic GVHD for a median (range) of 4.5 (0.1-36.7) years, with a median (range of 0.5 (0-3.6) years from most recent transplant to chronic GVHD diagnosis. Among those employed full- or part-time at the time of their most recent transplant (n=80), 61.3% reported taking disability leave, 58.8% worked reduced hours, 27.5% took a less demanding job, and 33.8% left a job because of chronic GVHD. Additionally, 71.3% believed they had lost income due to chronic GVHD. Among all respondents, 72.1% reported receiving regular caregiver assistance. Respondents commonly reported employment changes among unpaid caregivers (34.5% reduced their working hours; 16.6% terminated a job).

CONCLUSIONS

HSCT survivors who develop chronic GVHD are vulnerable to employment changes and financial hardship. This analysis highlights the need for effective therapies and improved symptom management to reduce the multifaceted burden of chronic GVHD on patients and their caregivers and ultimately improve long-term HSCT outcomes.

A longitudinal multidimensional rehabilitation program for patients undergoing allogeneic blood and marrow transplantation (CaRE-4-alloBMT): Protocol for a phase II feasibility pilot randomized controlled trial

BACKGROUND

Allogeneic blood and marrow transplantation (alloBMT) is a curative treatment for blood cancers associated with various treatment-related adverse events and morbidities. Current rehabilitation programs are limited for patients undergoing alloBMT and research is urgently needed to test the acceptability and effectiveness of these programs. In response, we developed a 6-month multidimensional longitudinal rehabilitation program that spans from pre transplant to 3 months post transplant discharge (CaRE-4-alloBMT).

METHODS

This study is a phase II randomized controlled trial (RCT) conducted at the Princess Margaret Cancer Centre in patients undergoing alloBMT. A total of 80 patients stratified by frailty score will be randomized to receive usual care (n = 40) or CaRE-4-alloBMT plus usual care (n = 40). The CaRE-4-alloBMT program includes individualized exercise prescriptions, access to online education through a dedicated self-management platform, wearable technology for remote monitoring, and remote tailored clinical support. Feasibility will be assessed by examining the recruitment and retention rates and adherence to the intervention. Safety events will be monitored. Acceptability of the intervention will be assessed through qualitative interviews. Secondary clinical outcomes will be collected through questionnaires and physiological assessments at baseline (T0, 2-6 weeks pre-transplant), transplant hospital admission (T1), hospital discharge (T2), and 3 months post-discharge (T3).

CONCLUSION

This pilot RCT study will determine the feasibility and acceptability of the intervention and study design and will inform full-scale RCT planning.

Effects of Exercise Programs on Psychoemotional and Quality-of-Life Factors in Adult Patients with Cancer and Hematopoietic Stem Cell Transplantation or Bone Marrow Transplantation: A Systematic Review

This review analyzed the effects of an exercise program on psychoemotional and quality-of-life (QoL) factors in adult patients with cancer and hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT). Studies were identified from the PubMed and Web of Science databases (from inception to 24 August 2022), according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The methodological quality of the included studies was assessed with the Physiotherapy Evidence Database (PEDro) scale, based in turn on the Delphi list. A total of 20 randomized controlled studies were included with 1219 participants. The main result of this systematic review is that exercise program interventions produce improvements on psychoemotional and QoL factors in adult patients with cancer and HSCT or BMT. Moreover, exercise programs may have a beneficial effect on health, maintaining or increasing the patient's QoL. Further, it has a positive effect on the prevention and control of transplant complications in combination with medical treatment.

Patient-reported symptom burden and impact on daily activities in chronic graft-versus-host disease

BACKGROUND

Chronic graft-versus-host disease (GVHD) is a potentially life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT) treatment for hematologic malignancies. There are limited patient-reported data concerning symptom burden and effects on activities of daily living (ADL).

METHODS

The cross-sectional Living With Chronic GVHD Patient Survey was administered online in the United States (May-August 2020) to participants aged ≥18 years who underwent allogeneic HSCT, were diagnosed with chronic GVHD by a healthcare provider, and self-reported active chronic GVHD (within past 5 years). Information on patient demographics, disease characteristics, symptom burden, and ability to perform ADL was collected. Symptom burden was assessed using the validated Lee Symptom Scale (range from 0-100 with higher scores indicating greater burden). All data were summarized using descriptive statistics; no formal statistical comparisons were conducted.

RESULTS

Out of 580 participants who entered the survey screener, 165 participants (28.4%) across 33 states fulfilled all study eligibility criteria, completed the entire survey, and were included (age: mean [SD], 53.7 (13.8) years; median [range], 57.0 [18-78] years; female, n = 105 [63.6%]; White, n = 137 [83.0%]). Respondents described their chronic GVHD severity primarily as moderate (n = 54 [32.7%]) or severe (n = 102 [61.8%]) at the time when symptoms were at their worst. One-third of respondents (33.9%) indicated that their chronic GVHD symptoms were at their worst for ≥1 year in duration. Mean (SD; range) Lee Symptom Scale score was 44.8 (19.4; 2-100); 44% of respondents considered "dry eye" the most burdensome symptom. Almost half of respondents (n = 73 [44.2%]) rated their overall quality of life (QoL) as poor. Participants reported a detrimental impact of symptoms on ADL, including basic activities (eg, eating, personal hygiene, dressing).

CONCLUSIONS

Survey respondents self-reported high chronic GVHD symptom burden and felt that their symptoms severely interfered with physical function and ADL. Effective strategies to mitigate chronic GVHD symptoms are needed to improve QoL among HSCT survivors.

Content analysis and dermatologic gaps in online patient education materials for graft-versus-host disease

Graft-versus-host disease (GVHD) is a complex systemic disease which is associated with significant physical and psychological distress in patients. Given the complexity of this disorder and its multifactorial effects, it is important for patients to have access to education and learning about their disease. Patient education has been shown to reduce the uncertainty and stress that follows complex diseases such as GVHD. To our knowledge no studies have evaluated the content of patient education materials on GVHD, especially from a dermatologic perspective. Despite the complexity of GVHD, cutaneous manifestations are common and often require management by dermatology. In this cross-sectional study, a Google search engine was utilized to assess websites for information on GVHD etiology, pathophysiology, symptoms, treatment, coverage of Acute GVHD, Chronic GVHD, cutaneous presentations, dermatologic management, and quality of life. It was evident that there was inconsistent inclusion of cutaneous manifestations of acute and chronic GVHD and dermatologic management of GVHD. Results of this study emphasize the need for more robust integration of skin-specific information guided by expert dermatologist opinion in publicly available patient education materials online.

A Phase 1 Thorough QT/QTc Study of Therapeutic and Supratherapeutic Doses of Belumosudil in Healthy Subjects

Belumosudil is a selective Rho-associated, coiled-coil-containing protein kinase-2 inhibitor. In this crossover design thorough QT/QTc study, single therapeutic (200 mg) and supratherapeutic (1000 mg) oral doses of belumosudil, moxifloxacin (positive control), and placebo were administered to 34 subjects. Twelve-lead electrocardiograms and serial pharmacokinetic sampling were acquired. The effect of belumosudil on the placebo-corrected, change-from-baseline QTcF was small, and an effect exceeding 10 ms could be excluded across all time points with both doses. Using concentration-QTc analysis, an effect on ΔΔQTcF >10 ms can be excluded up to belumosudil concentrations of ≈12 080 ng/mL, more than 2-fold above mean C_max after the supratherapeutic dose. There was no clinically relevant effect on heart rate or cardiac conduction (ie, the PR and QRS intervals) for belumosudil. No differences in safety were noted between belumosudil and placebo treatment. Assay sensitivity was demonstrated by moxifloxacin's effect on the QTc interval. In conclusion, belumosudil at therapeutic and supratherapeutic doses did not have a clinically meaningful effect on electrocardiogram parameters.

Limonium tetragonum Promotes Running Endurance in Mice through Mitochondrial Biogenesis and Oxidative Fiber Formation

The purpose of this study was to examine whether Limonium tetragonum, cultivated in a smart-farming system with LED lamps, could increase exercise capacity in mice. C57BL/6 male mice were orally administered vehicle or Limonium tetragonum water extract (LTE), either 30 or 100 mg/kg, and were subjected to moderate intensity treadmill exercise for 4 weeks. Running distance markedly increased in the LTE group (100 mg/kg) by 80 ± 4% compared to the vehicle group, which was accompanied by a higher proportion of oxidative fibers (6 ± 6% vs. 10 ± 4%). Mitochondrial DNA content and gene expressions related to mitochondrial biogenesis were significantly increased in LTE-supplemented gastrocnemius muscles. At the molecular level, the expression of PGC-1α, a master regulator of fast-to-slow fiber-type transition, was increased downstream of the PKA/CREB signaling pathway. LTE induction of the PKA/CREB signaling pathway was also observed in C2C12 cells, which was effectively suppressed by PKA inhibitors H89 and Rp-cAMP. Altogether, these findings indicate that LTE treatment enhanced endurance exercise capacity via an improvement in mitochondrial biosynthesis and the increases in the formation of oxidative slow-twitch fibers. Future study is warranted to validate the exercise-enhancing effect of LTE in the human.

Safety analysis of patients who received ruxolitinib for steroid-refractory acute or chronic graft-versus-host disease in an expanded access program

Outside of clinical trials and before commercial availability for acute and chronic graft-versus-host disease (GVHD), the Janus kinase (JAK) 1/JAK2 inhibitor ruxolitinib was available to US patients with steroid-refractory GVHD through an open-label, multicenter expanded access program (EAP) sponsored by Incyte Corporation. To assess the safety of ruxolitinib, data on serious adverse events (SAEs) reported among patients in the EAP were collected. Patients ≥12 years old who received allogeneic hematopoietic cell transplantation for a hematologic malignancy and developed any-grade acute or chronic steroid-refractory GVHD received ruxolitinib at a starting dose of 5 mg twice daily (BID; acute GVHD) or 10 mg BID (chronic GVHD). At data extraction (May 8, 2020), 60 patients with acute GVHD and 549 with chronic GVHD were enrolled. In the acute and chronic GVHD cohorts, 41 (68.3%) and 186 (33.9%) patients, respectively, had ≥1 SAE. Sepsis (8.3%) and respiratory failure (6.7%) were the most common SAEs in the acute GVHD cohort, and pneumonia (4.9%), sepsis (3.8%), and lung infection (3.5%) in chronic GVHD. Infection SAEs were reported in 23.3% and 20.0% of patients with acute and chronic GVHD, respectively. Overall, these safety findings demonstrate the tolerability of ruxolitinib in steroid-refractory GVHD.

Phase 1 Studies to Evaluate the Food Effect and Relative Bioavailability of Tablet and Capsule Formulations of Belumosudil in Healthy Adult Subjects

Belumosudil is a selective Rho-associated coiled-coil containing protein kinase 2 inhibitor. A capsule formulation was used during early clinical development of belumosudil; it was later replaced by a tablet formulation, which mimicked the capsule's release properties and facilitated manufacturing scalability. To assess belumosudil's pharmacokinetics, including potential food effects, and evaluate the relative bioavailability of the 2 formulations, 2 phase 1 clinical trials were conducted. Administration of both belumosudil tablets and capsules with food increased exposure ≈2× as compared to the fasted state and delayed time to maximum concentration by 0.5 hour, indicating a decrease in the rate but increase in the extent of absorption with fed administration. Relative bioavailability was slightly higher when belumosudil was administered as tablets vs capsules, although the difference was not clinically meaningful. Safety and tolerability were generally consistent with the known safety profile of belumosudil. The results of these studies support administration of belumosudil with food.

Health State Utilities for Sickle Cell Disease: A Catalog Prepared From a Systematic Review

OBJECTIVES

Sickle cell disease (SCD) is a complex, chronic condition that impairs health-related quality of life of affected individuals and their caregivers. As curative therapies emerge, comprehensive cost-effectiveness models will inform their value. These models will require descriptions of health states and their corresponding utility values that accurately reflect health-related quality of life over the disease trajectory. The objectives of this systematic review were to develop a catalog of health state utility (HSU) values for SCD, identify research gaps, and provide future directions for preference elicitation.

METHODS

Records were identified through searches of PubMed and Embase, Tufts Medical Center Cost-Effectiveness Analysis Registry, reference lists of relevant articles, and consultation with SCD experts (2008-2020). We removed duplicate records and excluded ineligible studies. For included studies, we summarized the study characteristics, methods used for eliciting HSUs, and HSU values.

RESULTS

Five studies empirically elicited utilities using indirect methods (EQ-5D) (n = 3) and Short Form-6 Dimension (n = 2); these represent health states associated with general SCD (n = 1), SCD complications (n = 2), and SCD treatments (n = 3). Additionally, we extracted HSUs from 7 quality-adjusted life-years-based outcome research studies. The HSU among patients with general SCD without specifying complications ranged from 0.64 to 0.887. Only 36% of the HSUs used in the quality-adjusted life-year-based outcomes research studies were derived from individuals with SCD. No study estimated HSUs in caregivers.

CONCLUSIONS

There is a dearth of literature of HSUs for use in SCD models. Future empirical studies should elicit a comprehensive set of HSUs from individuals with SCD and their caregivers.

Effects of Exercise Programs on Physical Factors and Safety in Adult Patients with Cancer and Haematopoietic Stem Cell Transplantation: A Systematic Review

This study looks at the effects of exercise programs on physical factors and safety in adult patients with cancer and hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT). A systematic search was performed in the PubMed and Web of Science databases (from inception to 26 August 2021). A review was carried out following the Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) checklist. The methodological quality of the included studies was assessed with the Physiotherapy Evidence Database (PEDro) scale, based, in turn, on the Delphi list. A total of 25 randomized controlled trials studies were included, comprising 1434 patients. The most significant result of this systematic review is that exercise program interventions are safe and produce positive changes in cardiorespiratory fitness, muscle strength, and the functional mobility-state in adult patients with cancer and HSCT or BMT. Only 3 patients from the 711 participants in the exercise interventions (i.e., 0.42%) reported adverse events related to exercise interventions. Moreover, exercise training programs may have a cardiological and muscular protective effect, as well as a healthy effect on the prevention and control of transplant complications, improving health outcomes.

Osteopathic Treatment and Evaluation in the Clinical Setting of Childhood Hematological Malignancies

Simple Summary

Children: adolescents, and young adults who are affected by hematological malignancies and who are undergoing intensive phases of cancer treatment including hematopoietic stem cell transplantation, experience diminished functional ability. This study was aimed at assessing if osteopathic treatment and evaluation can be used when an 11-week precision-based exercise program is run inside the hospital. Our results support that osteopathy plus precision-based intervention could be a desirable support in the clinical prise en charge of these children and adolescents. Osteopathy is a safe method for the evaluation of clinical conditions and requires strong multidisciplinary synergy between pediatricians and exercise physiologists.

Abstract

Children: adolescents, and young who are adults affected with hematological malignancies (CAYA-H) and who are undergoing intensive phases of cancer treatment, including hematopoietic stem cell transplantation (HSCT), experience diminished functional ability. This study was aimed at assessing the feasibility, efficacy, safety, and satisfaction of an osteopathic intervention in CAYA-H attending an 11-week precision-based exercise program (PEx). All of the participants were given 4–10 treatments according to the prescription ordered by the sports medicine doctor in charge of the PEx, and the following outcomes were assessed: (1) spinal column range of motion (ROM) by palpation; (2) lower and upper limb joints ROM by a goniometer; (3) orthostatic posture by plumb line assessment; (4) chest and abdomen mobility by inspection and palpation; (5) cranial-sacral rhythmic impulse (CRI) by palpation; and (6) adverse effects. Goal attainment scaling (GAS) was used to identify the accomplishment of a desired clinical result. Moreover, HSCT patients who were affected with graft-versus-host disease and/or osteonecrosis had their joints assessed in terms of ROM as tools to monitor the effectiveness of immunosuppressive treatment. A total of 231 CAYA-H were identified, and 104 participated in the study (age 10.66 ± 4.51 yrs; 43% F). PEx plus osteopathy reached positive GAS scores by improving the ROMs of the spinal column and/or limbs (81% and 78%, respectively), chest and abdomen mobility (82%), and CRI (76%). Only minor reversible adverse effects were noticed during the study. Together, our data seem to initiate a new course where osteopathy could be useful in evaluating structural edges due to the clinical history of each CAYA-H. Given the contributions that were obtained by the GAS scores, osteopathic treatment seems to reveal interesting potential that can be targeted in the future.

Clinical characterization and cytokine profile of fatigue in hematologic malignancy patients with chronic graft-versus-host disease

Limited information is available regarding clinical and biological properties of fatigue in patients with chronic graft-versus-host disease (cGvHD). Patients with moderate-to-severe cGvHD per NIH criteria were enrolled on a cross-sectional study and categorized as "fatigued" if SF-36 vitality score was <40. Clinical and laboratory parameters of fatigued (n = 109) and nonfatigued patients (n = 72) were compared. In univariate analysis, walk velocity, NIH joint-fascia score, human activity profile, and SF-36 physical and mental health self-report scales were correlates of fatigue. No cGvHD biomarkers were associated with fatigue. NIH joint score, Lee sleep and depression questions, and PG-SGA activities and function score jointly predicted fatigue. Though higher rates of depression and insomnia were reported in the fatigued group, antidepressant or sleep aid use did not differ between groups. Survival ratio was not significantly different by fatigue status. Pathophysiology of fatigue in patients with cGvHD is complex and may involve mechanisms unrelated to disease activity. Patients with cGvHD experiencing fatigue had higher rates of untreated depression and insomnia, highlighting the need to focus clinical management of these conditions to improve health-related quality of life.

Association between plasma procollagen type III N-terminal peptide (P3NP) levels and physical performance in elderly men: The Korean Frailty and Aging Cohort Study (KFACS)

BACKGROUND

Physical performance decline associated with aging is clinically important in the development of disability in the older population. More recently, procollagen type III N-terminal peptide (P3NP) and synaptosomal-associated protein of 25 kDa (SNAP25) have been suggested as potential biomarkers for physical performance decline.

OBJECTIVE

The objective of this pilot study was to examine plasma P3NP and SNAP25 levels in relation to muscle mass, strength, and performance status, and to investigate the association of plasma P3NP and SNAP25 levels with sarcopenia components.

METHODS

Seventy-nine community-dwelling elderly men (mean age: 78.1 ± 3.5 years) were randomly selected and matched by age from the Korean Frailty and Aging Cohort Study. The sample was classified into the "normal," "low muscle mass only," "sarcopenia," and "low physical performance only" groups according to the criteria of the Asian Working Group for Sarcopenia 2019. Estimates and 95% confidence intervals (CIs) of log P3NP and log SNAP25 levels by muscle mass, strength, and performance status were obtained using a generalized linear model. Pearson correlations and multiple linear regression analyses were used to assess the association of log P3NP and log SNAP25 levels with appendicular skeletal muscle mass (ASM) index, handgrip strength, and physical performance.

RESULTS

Log P3NP levels tended to be associated with low physical performance compared with the normal group (estimate = 0.54; 95% CI = -0.05, 1.14; p = 0.072). Log P3NP levels were inversely associated with physical performance (short physical performance battery and five-times sit-to-stand test) after adjusting for potential confounders (all p < 0.05) and tended to have an inverse association with gait speed (p = 0.078). Log P3NP levels tended to have a positive correlation with the ASM index (r² = 0.042; p = 0.070), but not with handgrip strength (r² = 0.0009; p = 0.795). However, no significant association between plasma SNAP25 levels and physical performance was observed.

CONCLUSION

Plasma P3NP levels might be a potential biomarker for decreased physical performance in elderly men. Further studies with larger sample sizes are needed to confirm our findings.

Psychosocial aspects of hematopoietic stem cell transplantation

Hematopoietic stem cell transplantation (HSCT) has become a conventional and potentially curative treatment for various hematological diseases. As more sophisticated procedures have been developed and mortality rates have decreased, attention has shifted to the psychosocial challenges associated with transplantation. The psychosocial difficulties accompanying transplantation are addressed in the context of both quality of life (QOL) and psychopathological research. Among the psychiatric comorbidities of HSCT, anxiety, depression, sleep and sexual disorders, delirium and post-traumatic stress disorder are the most studied conditions. Recently, more attention has been focused on the psychosocial burden of caregivers. Devising recommendations for the management of psychiatric symptoms and psychosocial interventions in HSCT sufferers and close relatives is a major concern to consultation–liaison psychiatrists and transplant teams. This review synthesizes and critically evaluates the current literature on the psychosocial aspects of HSCT and appraises the clinical significance of these outcomes. Issues of QOL assessment; psychosocial functioning and QOL in the course of HSCT; impact of graft-versus-host disease and other predictors of QOL and psychosocial functioning; comorbid psychiatric disorders; and interventions to maintain or improve QOL and reduce psychopathology and psychosocial burden on family members are presented.

Analysis of factors associated with patient-reported physical functioning scores at discharge of allogeneic hematopoietic stem cell transplantation patients: a cross-sectional study

PURPOSE

The purpose of this study was to clarify the independent factors related to patient-reported physical functioning (PF) scores at discharge of patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS

A total of 103 patients who underwent allo-HSCT were included in this cross-sectional study. As a screening method, a single regression analysis was conducted with the PF domain in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at discharge as the dependent variable, and body mass index, adverse events related to HSCT, and objective physical functions as independent variables. Multiple regression analysis was performed with PF as the dependent variable and variables that passed the screening by single regression analysis and confounders as independent variables.

RESULTS

The mean PF score at discharge of the patients was 76.5 (standard deviation: 15.2). Based on the results of screening by the single regression analysis, length of stay, infections (+ / -), acute graft-versus-host disease grade, brief fatigue inventory score (BFI), knee extensor strength, and 6-min walk distance (6MWD) were included in the multiple regression analysis. BFI (B =  - 11.94, p < 0.001) and 6MWD (per 10 m) (B = 0.56, p = 0.001) were extracted as significant independent variables governing the PF at discharge in the multiple regression model (adjusted R² = 0.59).

CONCLUSION

Higher exercise tolerance and lower fatigue in patients who underwent allo-HSCT were associated independently with patient-reported better PF scores at discharge.

Role of Physical Activity and Cardiac Rehabilitation in Patients Undergoing Hematopoietic Stem Cell Transplantation

Hematopoietic stem cell transplantation (HSCT) is a standard treatment for several malignancies, and >50,000 HSCT are performed annually worldwide. As survival after HSCT improves, cardiovascular disease and associated risk factors have gained importance as a significant cause of morbidity and mortality in this cohort. In this article, we detail the risk factors for cardiovascular disease and their impact in patients undergoing HSCT. Additionally, we critically review the data on the impact of physical exercise in patients undergoing HSCT. Although limited by significant heterogeneity in methodologies, small sample sizes, attrition, and lack of long-term cardiovascular follow-up, most of these studies reinforce the beneficial effects of physical activity and exercise in this patient population. Cardiac rehabilitation (CR) is a structured exercise and lifestyle modification program that is typically instituted in patients who experience acute cardiovascular events. We review the data on CR in the oncologic and nononcologic populations with an aim of building a framework for use of CR in HSCT patients.

•

Patients surviving HSCT have a higher incidence of cardiovascular risk factors and cardiovascular disease than the general population.

•

Physical activity can improve cardiovascular fitness, strength, and quality of life and decrease fatigue in HSCT patients and survivors.

•

In addition to physical exercise, cardiac rehabilitation also involves dietary and smoking cessation counseling, medication management, and psychosocial support, and it may therefore offer a unique framework to mitigate cardiovascular risk in HSCT.

•

Early referral, cardiovascular risk stratification, monitoring for complications, and multimodal lifestyle interventions should form the backbone of cardiac rehabilitation in this population.

•

Outcome data on quality of life indices and survival as potential benefits of cardiac rehabilitation in HSCT are needed.

Physical function after lung transplantation for late-onset noninfectious pulmonary complications after allogeneic hematopoietic stem cell transplantation

PURPOSE

Late-onset noninfectious pulmonary complications (LONIPCs) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) are fatal, and lung transplantation is the only curative treatment. Although lung transplantation for LONIPCs may confer good survival rates, it is unclear whether or how impaired physical functioning is restored. Thus, this study aimed to investigate the long-term course and associated changes in physical functions after lung transplantation in patients with LONIPCs after allo-HSCT.

METHODS

This prospective cohort study enrolled 15 patients who received lung transplantation for LONIPCs after allo-HSCT between 2012 and 2018. Dyspnea scores, performance status, physical function, and exercise tolerance were assessed before lung transplantation and up to 2 years after transplantation.

RESULTS

Two years after lung transplantation, the dyspnea scores and performance status improved, but did not recover completely. Physical function was assessed using the knee extensor strength (KES) and 6-min walk test (6MWT); the results were poor until 3 months after transplantation but improved over 2 years. The 6MWT distance showed improvement to a nearly healthy level (562.7 m). Recovery of exercise tolerance was associated with recovery in % vital capacity (%VC; r=0.5) and KES (r=0.4) from 3 months to 2 years after lung transplantation. Furthermore, a flat thorax, which is a characteristic of patients with LONIPCs, affected the %VC at 2 years after transplantation (r=0.8).

CONCLUSION

Lung transplantation for LONIPCs may restore impaired physical function. A multifaceted rehabilitation program should be considered, especially to improve muscle weakness and pulmonary function.

Should healthcare organisations offer ongoing rehabilitation services for patients undergoing haematopoietic cell transplant? A narrative review

Purpose

Hematopoietic stem cell transplant (HSCT) patients can suffer from long-term transplant-related complications that affect their quality of life and daily activities. This study, a narrative review, aims to report the impact of HCT complications, the benefits of rehabilitation intervention, the need for long-term care and highlights the research gap in clinical trials involving rehabilitation.

Design/methodology/approach

A comprehensive search strategy was performed on several databases to look for relevant articles published from 1998 to 2018. Articles published in English with the following terms were used: hematopoietic stem cell transplant, chronic graft-versus-host disease, rehabilitation, exercise, physical therapy, occupational therapy. A patient/population, intervention, comparison, and outcomes (PICO) framework was employed to ensure that the search strategies were structured and precise. Study year, design, outcome, intervention, sample demographics, setting and study results were extracted.

Findings

Of the 1,411 records identified, 51 studies underwent title/abstract screening for appropriateness, 30 were reviewed in full, and 19 studies were included in the review. The review found that, for the majority of patients who underwent HSCT and developed treatment-related complications, rehabilitation exercises had a positive impact on their overall quality of life. However, exercise prescription in this patient group has not always reflected the scientific approach; there is a lack of high-quality clinical trials in general. The review also highlights the need to educate healthcare policymakers and insurance companies responsible for rationing services to recognise the importance of offering long-term follow-up care for this patient group, including rehabilitation services.

Practical implications

A large number of HSCT patients require long-term follow-up from a multidisciplinary team, including rehabilitation specialists. It is important for healthcare policymakers and insurance companies to recognise this need and take the necessary steps to ensure that HSCT patients receive adequate long-term care. This paper also highlights the urgent need for high-quality rehabilitation trials to demonstrate the feasibility and importance of rehabilitation teams.

Originality/value

Healthcare policymakers and insurance companies need to recognise that transplant patients need ongoing physiotherapy for early identification of any functional impairments and appropriate timely intervention.

Functional capacity, pulmonary function, and quality of life in hematopoietic stem cell transplantation survivors

OBJECTIVE

Hematopoietic stem cell transplantation (HSCT) is used as a treatment for several diseases. The objective was to evaluate the functional capacity, pulmonary function, and quality of life (QoL) in HSCT survivors.

METHODS

The patients were submitted to spirometry and six-minute walk test (6MWT) and evaluation of QoL (Functional Assessment of Cancer Therapy Bone Marrow Transplantation-FACT-BMT) and the level of physical activity (Human Activity Profile-HAP) in the post-HSCT outpatient ambulatory.

RESULTS

The sample was composed of 103 individuals with a mean age of 42.1 ± 12 and a median HSCT time of 5 (2-11) years. The average distance walked in the 6MWT was 524.7 ± 73.5 m; the FACT-BMT score, 82 ± 8.7 points; FEV₁, 76.8 ± 22.6%; and HAP, 71.9 ± 11.2 points. There was a significant difference between debilitated and physically active individuals for the variables: forced expiratory volume in the first second (FEV₁) in liters (p = 0.008) and % of predicted (p = 0.017), FEV₁/FVC (p = 0.032), distance on the 6MWT (p < 0.001), fatigue after the 6MWT (p < 0.001), and physical well-being (p = 0.005).

CONCLUSIONS

HSCT survivors have long-term changes in functional capacity, pulmonary function, and QoL. Subjects more active had better results in pulmonary function and functional capacity.

Impact of cGVHD on socioeconomic outcomes in survivors with pediatric hematopoietic stem cell transplant in Japan: a cross-sectional observational study

We conducted a cross-sectional observational study investigating socioeconomic status among Japanese survivors of pediatric hematopoietic stem cell transplantation (HCT) and the impact of chronic graft-versus-host disease (cGVHD) on socioeconomic outcomes, which are topics not well explored in the previous research. We collected data on socioeconomic outcomes from 442 HCT survivors through a questionnaire and obtained demographic and clinical information from their attending physicians and a national database between February 2013 and November 2014. We used logistic regression analysis to examine the relationship between cGVHD and socioeconomic outcomes in allogeneic HCT (allo-HCT) survivors. Most survivors did not experience socioeconomic problems. Nevertheless, allo-HCT survivors with cGVHD aged 8-15 years had poorer economic status (p = 0.013), and allo-HCT survivors with cGVHD aged ≥ 16 years were more likely to have never married (p = 0.034) and less likely to have more than a high school education (p = 0.023), compared with allo-HCT survivors without cGVHD. Thus, cGVHD in Japanese allo-HCT survivors was a risk factor for economic difficulties for those aged 8-15 years, and for never marrying and low educational achievement in those aged ≥ 16 years.

Epidemiology and Treatment of Chronic Graft-versus-Host Disease Post-Allogeneic Hematopoietic Cell Transplantation: A US Claims Analysis

Chronic graft-versus-host disease (cGVHD) is a complication of hematopoietic cell transplantation (HCT). Although the clinical outcomes of cGVHD are well documented, few studies have assessed treatment practices outside of clinical trials. The present study aimed to quantify the prevalence of cGVHD, examine provider prescribing patterns, and evaluate the healthcare cost and resource utilization (HCRU) in a US cGVHD population. We analyzed anonymized claims from the Medicare Fee-for-Service (FFS) 5% sample for beneficiaries enrolled between 2013 and 2016 and PharMetrics commercial 2013 to 2018 databases to identify cGVHD in allogeneic HCT recipients. cGVHD was identified based on International Classification of Diseases Ninth/Tenth Revision diagnosis codes for cGVHD or unspecified GVHD with a first diagnosis >180 days post-HCT or a maintained unspecified GVHD diagnosis for >12 months postindex of unspecified GVHD diagnosis. Longitudinal and line of therapy (LOT) analyses were based on the PharMetrics dataset for 2013 to 2018. Healthcare costs were calculated by adding the inpatient, outpatient, and pharmacy insurer and beneficiary paid amounts for the commercially insured population. Total HCRU was assessed using the number of inpatient and outpatient visits following the initial cGVHD diagnosis. In 2016, the projected prevalence of cGVHD in the United States based on the Medicare FFS and PharMetrics commercial databases was 14,017 individual patients. Within 3 years after undergoing allogeneic HCT, 42% of patients developed cGVHD; 66% of the cGVHD patients had a prior diagnosis of acute GVHD. The majority of cGVHD patients received at least one systemic therapy; 71% and 47% of cGVHD patients progressed to a second and third LOT, respectively. A total of 24 unique therapeutic agents and more than 150 combinations were used in the second and third LOTs. Corticosteroids and corticosteroid combination therapy were the most common forms of treatment across all examined LOTs. Furthermore, the most commonly used agents in the first LOT, second LOT, and third LOT were corticosteroids only, calcineurin inhibitors only, and corticosteroids only, respectively. In the 12 months postdiagnosis, cGVHD patients had an average of 21.0 cGVHD-related inpatient and outpatient visits (2.8 inpatient and 18.2 outpatient visits). A significant proportion of allogeneic HCT recipients continue to develop cGVHD, and despite advances in the understanding of cGVHD, corticosteroids remain the mainstay of therapy. Patients often progress beyond the first LOT, at which time the utilization of systemic therapies is highly variable, demonstrating the need for evidence-based treatment approaches.

Rehabilitation Interventions in the Multidisciplinary Management of Patients With Sclerotic Graft-Versus-Host Disease of the Skin and Fascia

Graft-versus-host disease (GVHD) is a multisystemic disorder that affects 30%-80% of patients who undergo allogeneic hematopoietic stem cell transplantation 10%-15% of GVHD patients develop sclerotic features affecting the skin or deeper tissues, leading to functional limitations and poor quality of life. There is limited literature regarding the indications and efficacy of specific rehabilitative interventions in sclerotic GVHD (sclGVHD). In this article, we summarize the current evidence supporting rehabilitation intervention in sclGVHD and offer our approach to the multidisciplinary management of this disease. In addition, we review techniques that have been employed in other sclerotic skin diseases (eg, iontophoresis, extracorporeal shock waves, botulinum toxin A, adipose derived stromal vascular fraction), but that require further validation in the sclGVHD setting. Ultimately, optimal care for this complex disease requires a multidisciplinary approach that includes a rehabilitation and adaptive program tailored to each patient's needs.

Importance of Monitoring Physical Function for Quality of Life Assessments in Hematopoietic Stem Cell Transplantation Patients: A Prospective Cohort Study

BACKGROUND/AIM

Physical function is known to decrease after hematopoietic stem cell transplantation (HSCT), with the most substantial impairment noted at 90 days post-transplantation. Little is known about the natural course of physical function during the acute post-transplant period preciously. The aim of the study was to monitor the changes in physical function through serial evaluations of the physical function, and identify the effect of physical function on QoL during the acute post-transplant period.

PATIENTS AND METHODS

This prospective cohort study included 41 patients admitted for planned autologous or allogeneic HSCT. Physical impairment was evaluated with decrease in the de Morton Mobility Index (DEMMI) every week and defined as a DEMMI score of more than 2 points after HSCT. The outcome variables for QoL included visual analogue scale (VAS), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and Zung Self-rating Depression Scale (SDS) at enrollment and discharge.

RESULTS

Based on DEMMI scores, 24.40% of all HSCT patients showed physical impairment, for whom the DEMMI score showed an overall decrease during hospitalization with significant differences in scores at 1, 2, and 3 weeks after HSCT, between 1 week before and 3 weeks after HSCT, and between 1 and 3 weeks after HSCT. There was no significant difference of VAS between admission and discharge between the groups. Each functional subscale of EORTC QLQ-C30 differed significantly between the groups, with lower scores in the physical impairment group. There was only a significant difference in SDS at discharge between the groups. QoL pre-transplantation can be a predictive factor for physical impairment during the acute post-transplant period, which can be detected in the early period after HSCT.

CONCLUSION

Patients during acute post-transplant period had physical impairment and QoL of pre-transplantation was considered a predictive factor for physical impairment. The physical impairment can be detected in the early period after HSCT. Therefore, monitoring of standardized functional outcome measures is important to prevent physical impairment following HSCT.

Lessons learned from a pilot randomized clinical trial of home-based exercise prescription before allogeneic hematopoietic cell transplantation

Allogeneic hematopoietic cell transplantation (alloHCT) is a life-saving technology that can cure otherwise incurable diseases, but imposes significant physiologic stress upon recipients. This stress leads to short-term toxicity and mid- to long-term physical function impairment in some recipients. Exercise interventions have demonstrated preliminary efficacy in preserving physical function in HCT recipients, but the role of these interventions prior to HCT (prehabilitative) is less known. We tested a 5- to 12-week, prehabilitative higher intensity home-based aerobic exercise intervention in a randomized study of alloHCT candidates. Of 113 patients screened, 34 were randomized to control or intervention groups, 16 underwent pre- and post-intervention peak oxygen consumption (VO2peak) testing, and 12 underwent pre- and post-intervention 6-min walk distance (6MWD) testing. No significant differences in VO2peak or 6MWD were seen pre- to post-intervention between intervention and control groups, but final numbers of evaluable participants in each group were too small to draw inferences regarding the efficacy of the intervention. We conclude that the design of our prehabilitative intervention was not feasible in this pilot randomized study, and make recommendations regarding the design of future exercise intervention studies in alloHCT.

Exercise before, during, and after Hospitalization for Allogeneic Hematological Stem Cell Transplant: A Feasibility Randomized Controlled Trial

People with cancer who undergo allogeneic hematological stem cell transplant (allo-HSCT) experience significant deconditioning that can compromise quality of life. Exercise has shown to be beneficial before or after allo-HSCT; however, little is known about exercise therapy delivered across the continuum of care. We conducted a feasibility randomized controlled trial of exercise delivered prior to admission, during the inpatient stay, and after discharge versus control in people with planned allo-HSCT. Feasibility was assessed via recruitment and retention rates, the incidence of adverse events, and adherence to the exercise prescription. Estimates of efficacy were measured at baseline, one week prior to hospital admission, and 100 days and one year after transplant. The recruitment and retention rates were 20% and 33%, respectively. One serious adverse event occurred during the baseline six-minute walk test that precluded participation in the study and no adverse events were associated with the intervention. From baseline to pre-transplant, the intervention group improved six-minute walk test distances by 45 m (95% CI: −18.0 to 108.7)—a finding that warrants further investigation with an adequately powered trial. Our study contributes important feasibility considerations and pilot data for future exercise intervention research in allo-HSCT recipients.

Psychometric properties of the Activities Scale for Kids-performance after allogeneic hematopoietic stem cell transplantation in adolescents and children : Results of a prospective study on behalf of the German-Austrian-Swiss GVHD Consortium

Background

The psychometric properties of an instrument, the Activity Scale for Kids-performance (ASKp), were assessed which was proposed to capture physical functioning after allogeneic hematopoietic stem cell transplantation (HSCT). Additionally, this multicenter observational prospective study investigated the influence of clinical correlates focusing on chronic graft-versus-host disease (cGVHD).

Methods

Patient-reported ASKp, clinician-reported Karnofsky/Lansky status (KPS/PSS), patient characteristics and cGVHD details were assessed of 55 patients with a median age of 12 years at baseline after day +100 post-HSCT and every 3 months during the next 18 months. The psychometric properties were evaluated and ASKp and KPS/PSS status was compared using ANOVAS and multiple regression models.

Results

The German version of the ASKp showed good psychometric properties except for ceiling effects. Discrimination ability of the ASKp was good regarding the need for devices but failed to predict cGVHD patients. Both the ASKp and the KPS/PSS were associated with patients after adoptive cell therapy being in need for devices, suffering from overlap cGVHD and from steroid side effects but not with patients’ age and gender. In contrast to the KPS/PSS the ASKp only showed significant differences after merging moderate and severe cGHVD patients when comparing them to No-cGVHD (F = 4.050; p = 0.049), being outperformed by the KPS/PSS (F = 20.082; p < 0.001).

Conclusion

The ASKp showed no clear advantages compared to KPS/PSS even though economical and patients’ effort was higher. Further application range may be limited through ceiling effects. Both should be taken into consideration. Therefore, the results may not support the usage of ASKp after HSCT and rather suggest KPS/PSS, both patient and clinician reported.

Comparison of HLA-matched sibling and unrelated donor transplantation in adult patients with acquired severe aplastic anemia

The recent improvements in the outcomes of severe aplastic anemia (SAA) patients who received allogeneic stem cell transplantation (SCT) from unrelated donors (URD) suggest the possibility of its alternative first-line treatment. To address this issue, results of adult SAA patients receiving allogeneic SCT were compared between the following three donor-type groups: 8/8-matched sibling (MSD; n = 153), 8/8 well-matched unrelated (WM-URD; n = 72), and 6-7/8 partially matched unrelated (PM-URD; n = 33). Proportion of patients who experienced immunosuppressive treatment failures was significantly higher in the URD groups than in the MSD group (P< 0.01). The incidences of graft failure and transplant-related mortality, and graft-vs.-host disease-free, failure-free survival rates of the MSD, WM-URD, and PM-URD groups were 14.6, 0, and 0% (P< 0.01); 6.1, 10.3, and 21.7% (P= 0.03); and 76.7, 55.5, and 51.5% (P< 0.01), respectively. The overall survival (OS) rate of the MSD group (93.9%) was higher than that of the PM-URD (78.3%; P < 0.01) group, but not to that of the WM-URD (86.2%; P= 0.18) group. Our study showed comparable OS between the MSD group and WM-URD group, which suggest that the URD-SCT can be used as a first-line treatment for adult SAA patients with WM-URD.

Individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation: a feasibility study

PURPOSE

The purpose of this study is to evaluate the feasibility of an individualized exercise program for people undergoing hematopoietic stem cell transplantation.

METHODS

This is a feasibility study of an individualized in-hospital exercise training program for people undergoing hematopoietic stem cell transplantation. Participants performed the exercise program based on daily clinical, hemodynamic and hematological assessment. The program was carried out on a daily basis for 20-40 min during their hospital admission. The primary outcome was feasibility (recruitment, adherence and attrition rates) of the exercise program. The secondary outcomes were functional capacity, peripheral muscle strength, and health-related quality of life evaluated on admission and prior to hospital discharge. The adverse events rate was recorded during the intervention.

RESULTS

Twenty-six participants (58% female), aged 40 ± 15 (mean ± SD) years were included. The exercise program feasibility was demonstrated by 100% recruitment, 86% exercise adherence and 12% attrition rates with no adverse events recorded. Significant differences were observed in functional capacity (p = 0.03), upper and lower-limb muscle strength (p = 0.01) from admission to discharge (23 ± 7 d).

CONCLUSIONS

An individualized exercise training program based on daily clinical parameters is feasible for hospitalized patients undergoing hematopoietic stem cell transplantation. This intervention warrants further investigation in a randomized controlled trial. Implications for rehabilitation The individualized in-hospital exercise training program guided by daily clinical, hemodynamic and hematologic parameters is feasible, safe and with good adherence in people undergoing hematopoietic stem cell transplantation. People undergoing hematopoietic stem cell transplantation may improve functional capacity and upper and lower limb muscle strength following in-hospital exercise training program. The individualized in-hospital exercise training program could tentatively be introduced as part of the rehabilitation process in people undergoing hematopoietic stem cell transplantation.

Humanistic burden of patients with chronic graft-versus-host disease - systematic literature review of health-related quality of life and functional status

INTRODUCTION

Chronic graft-versus-host disease (GVHD) is a serious complication of allogeneic hematopoietic stem cell transplantation (HSCT). This study aims to provide a systematic overview of evidence on the health-related quality of life (HRQoL) and functional capacity of HSCT patients with National Institutes of Health (NIH)-defined chronic GVHD. Areas covered: English-language articles published between 2007 and 2017 were searched using PubMed. Studies that used the 2005 or 2015 NIH consensus criteria for the diagnosis and staging of chronic GVHD and had a cohort size of at least 100 patients were included. Expert opinion: Disease severity and organ involvement were the most important predictors of HRQoL and functionality in chronic GVHD patients. Further, identified predictors of HRQoL were nutrition status and functional capacity, while functional status was also associated with disease symptoms, nutrition status, age, and survival. Data regarding the effect of symptom bother on HRQoL were limited. Our findings confirm that the management of chronic GVHD should focus on improving not only clinical outcomes but also on HRQoL and functional capacity. Therefore, to evaluate new treatment options it is recommended to include patient relevant endpoints into prospective studies. This study also highlights the importance of nonpharmacological aspects in the management of chronic GVHD.

Negative impact of chronic graft-versus-host disease and glucocorticoid on the recovery of physical function after allogeneic hematopoietic stem cell transplantation

Quality of life of patients who undergo allogeneic hematopoietic stem cell transplantation (HSCT) temporally deteriorates and recovers over several years. We retrospectively evaluate the impact of chronic graft-versus-host disease (GVHD) and glucocorticoid on physical recovery. We included 162 patients who underwent their first allogeneic HSCT between October 2010 and December 2015 in a single hospital. All patients are planned to undergo physical function tests before and 1, 3, 12 months after allogeneic HSCT. Scores of knee extension strength and distance covered in the 6-min walk test (6MWT) recovered at the 12-month assessment. Both chronic GVHD and high dose glucocorticoid were associated with delayed recovery of body mass index (BMI), hand grip strength, knee extension strength, and duration of standing on one foot. Lung GVHD and high dose glucocorticoid had negative impact on the distance covered in the 6MWT. A multivariate analysis revealed that chronic GVHD and glucocorticoid was an independent risk factor for decreased BMI and delayed recovery of muscle strength, respectively. Our results suggest that high-risk patients who have chronic GVHD or who receive glucocorticoid therapy may require reduced dose of glucocorticoid and long-term physical support to recover physical function after transplantation.

Comparison of survival outcome between donor types or stem cell sources for childhood acute myeloid leukemia after allogenic hematopoietic stem cell transplantation: A multicenter retrospective study of Study Alliance of Yeungnam Pediatric Hematology-oncology

We compared transplant outcomes between donor types and stem cell sources for childhood acute myeloid leukemia (AML). The medical records of children with AML in the Yeungnam region of Korea from January 2000 to June 2017 were reviewed. In all, 76 children with AML (male-to-female ratio = 46:30) received allogenic hematopoietic stem cell transplantation (allo-HSCT). In total, 29 patients received HSCT from either a matched-related donor or a mismatched-related donor, 32 patients received an unrelated donor, and 15 patients received umbilical cord blood. In term of stem cell sources, bone marrow was used in 15 patients and peripheral blood in 46 patients. For all HSCT cases, the 5-year overall survival (OS) was 73.1% (95% CI: 62.7-83.5) and the 5-year event-free survival (EFS) was 66.1% (95% CI: 54.5-77.7). There was no statistical difference in 5-year OS according to the donor types or stem cell sources (P = .869 and P = .911). There was no statistical difference in 5-year EFS between donor types or stem cell sources (P = .526 and P = .478). For all HSCT cases, the 5-year relapse rate was 16.1% (95% CI: 7.3-24.9) and the 5-year non-relapse mortality (NRM) was 13.3% (95% CI: 5.1-21.5). There was no statistical difference in the 5-year relapse rate according to the donor types or stem cell sources (P = .971 and P = .965). There was no statistical difference in the 5-year NRM between donor types or stem cell sources (P = .461 and P = .470).

Better outcomes of modified myeloablative conditioning without antithymocyte globulin versus myeloablative conditioning in cord blood transplantation for hematological malignancies: A retrospective (development) and a prospective (validation) study

Cord blood transplantation (CBT) is an effective option for treating hematological malignancies, but graft failure (GF) remains the primary cause of therapy failure. Thus, based on myeloablative conditioning (MAC) of busulfan with cyclophosphamide (Bu/Cy) or total body irradiation with Cy (TBI/Cy), fludarabine (Flu) was added to Bu/Cy and cytarabine (CA) to TBI/Cy for a modified myeloablative conditioning (MMAC). To compare the prognosis of MMAC with MAC, we conducted a retrospective study including 58 patients who underwent CBT with MAC or MMAC from 2000 to 2011. Neutrophil and platelet engraftment rate, overall survival (OS) and disease free survival (DFS) were significantly higher in the MMAC group (adjusted hazard ratio [HR], 2.58, 2.43, 0.36 and 0.37; p < 0.01, p = 0.01, p = 0.02 and p = 0.02, separately). Nonrelapse mortality (NRM) was comparable (p = 0.183). To validate the outcomes noted in the MMAC group, we conducted a prospective single‐arm clinical trial including 188 patients who underwent CBT with MMAC from 2011 to 2015. Engraftment rate, survival and NRM of the MMAC group in the prospective trail (MMAC‐P) were similar to the MMAC group in the retrospective study (MMAC‐R). This study is the first to demonstrate the superiority of MMAC to MAC in CBT for hematological malignancies.

What's new?

Cord blood transplants can help patients with blood cancer, but too often, the transplant fails due to immune rejection or other problems. Typically, patients receive myeloablative conditioning (MAC) prior to CBT, but more intense regimen might improve transplant success. Here, the authors compared the success of modified myeloablative conditioning (MMAC) with conventional MAC by looking at 58 patients over an 11‐year period. They then followed up with a four‐year prospective study, including 188 patients who received cord blood transplant with MMAC. The modified conditioning regimen boosted graft success and improved survival of patients with hematological cancers.

Palliative care during and following allogeneic hematopoietic stem cell transplantation

PURPOSE OF REVIEW

The purpose of this review is to synthesize recent literature regarding the provision of palliative care to patients during and following allogeneic hematopoietic stem cell transplantation (HSCT), highlighting factors which mediate impairments in health-related quality of life in this patient population, and the intervention approaches and models of care delivery that clinicians can consider to address unmet needs for palliative care and to strengthen patient and family resiliency.

RECENT FINDINGS

Provision of palliative care simultaneous with the delivery of treatment directed at the underlying malignancy has emerged as a recommended practice for patients with advanced cancer and high-symptom burden, and a recent randomized trial demonstrates the effectiveness of early palliative care in reducing some of the symptom burden and mood disturbances associated with HSCT. Although more research is needed, there is an expanding body of research-tested interventions to ameliorate the physical and psychological morbidity of HSCT across the transplant trajectory.

SUMMARY

Palliative care interventions delivered by an interdisciplinary team that includes transplant clinicians and palliative care across the HSCT trajectory can alleviate physical and psychological morbidity, thereby improving the patient and family experience of HSCT.

Transplants of unrelated cord blood or sibling allogeneic peripheral blood stem cells/bone marrow in adolescent and young adults with chronic myeloid leukemia: comparable outcomes but better chronic GVHD-free and relapse-free survival among survivors with cord blood

Adolescent and young adult (AYA) patients with hematological malignancy aged 15 to 39 years are recognized as a separate entity, and the efficacy and safety of unrelated cord blood transplantation (CBT) for chronic myeloid leukemia (CML) in AYA patients has not been reported. From March 2002 to June 2015, total of 106 CML patients received allogeneic hematopoietic cell transplantation (allo-HCT) in our center. Included in the present study were CML patients aged 15 to 39 years who received unrelated CBT or sibling allo-HCT, and 74 consecutive AYA patients with CML enrolled in this analysis. The day-100 cumulative incidences of grade 2–4 aGVHD and grade 3–4 aGVHD were similar following CBT and sibling-PBSCT/BMT. The cumulative incidences of cGVHD and extensive cGVHD were 21.7% and 5.3% in the CBT cohort, which were significantly lower than those in the sibling-PBSCT/BMT cohort (58.0% and 45.5%), respectively (p = 0.046, 0.008). There was no significant difference between the two cohorts in terms of transplant-related mortality (TRM), relapse, and long-term survival (overall survival and leukemia-free survival). The 5-year probability of GVHD-free/relapse-free survival (GRFS) was 47.9% and 33.4% in the CBT and the sibling-PBSCT/BMT cohorts, respectively (p = 0.632); among patients who survived more than 100 days after transplantation (n = 61), the 5-year probability of chronic GVHD-free, relapse-free survival (CRFS) was 66.2% in the CBT cohort, which was significantly higher than that in the sibling-PBSCT/BMT cohort (37.4%) (p = 0.037). Our study suggests that for AYA patients with CML, transplantation using unrelated CB offers comparable outcomes to sibling -PBSCT/BMT, including similar aGVHD, TRM, relapse, and long-term survival; however, from the perspective of quality of life, unrelated CBT have a lower incidence of cGVHD and a higher CRFS among survivors.

Quality of life of patients with graft-versus-host disease (GvHD) post-hematopoietic stem cell transplantation

OBJECTIVE

Assessing the quality of life of adult patients with hematological cancer in the 100 days after transplantation of hematopoietic stem cells and verifying whether the variable graft-versus-host disease (GvHD) is predictive of worse results.

METHOD

An observational correlational and quantitative study with 36 adult participants diagnosed with hematologic cancer who underwent hematopoietic stem cell transplantation from September 2013 to June 2015.

RESULT

The mean age was 37 years, 52.78% were female, and 61.11% were diagnosed with leukemia. Quality of life scores showed a significant impact between pre-transplantation and pre-hospital discharge, and also within the 100 days post-transplantation. The statistical analysis between the scores for the groups with and without GvHD showed a significant difference between the presence of the complication and worse results.

CONCLUSION

Quality of life is altered as a result of hematopoietic stem cells transplantation, especially in patients who have graft-versus-host disease.

OBJETIVO

Avaliar a qualidade de vida de pacientes adultos com câncer hematológico nos 100 dias do transplante de células-tronco hematopoéticas e verificar se a variável doença do enxerto contra o hospedeiro é preditiva de piores resultados.

MÉTODO

Estudo observacional, correlacional e quantitativo, com 36 participantes adultos, diagnosticados com câncer hematológico que se submeteram ao transplante de células-tronco hematopoéticas de setembro de 2013 a junho de 2015.

RESULTADO

A média de idade foi 37 anos, 52,78% eram do sexo feminino, e 61,11% com diagnóstico de leucemia. Os escores de qualidade de vida demonstraram impacto significativo entre o pré-transplante e a pré-alta hospitalar e entre os 100 dias pós-transplante. A análise estatística entre os escores dos grupos com e sem doença do enxerto contra o hospedeiro evidenciou significância entre a presença desta complicação e piores resultados.

CONCLUSÃO

A qualidade de vida é alterada em decorrência do transplante de células-tronco hematopoéticas, em especial nos pacientes que apresentam doença do enxerto contra o hospedeiro.

National Institutes of Health Hematopoietic Cell Transplantation Late Effects Initiative: The Patient-Centered Outcomes Working Group Report

In 2015, the National Institutes of Health convened six working groups to address the research needs and best practices for late effects of hematopoietic stem cell transplantation survivors. The Patient-Centered Outcomes Working Group, charged with summarizing the HRQOL evidence base, used a scoping review approach to efficiently survey the large body of literature in adult and pediatric HCT survivors over 1 year after transplantation. The goals of this paper are to (1) summarize the current literature describing patient-centered outcomes in survivors, including the various dimensions of health-related quality of life affected by HCT, and describe interventions tested to improve these outcomes; (2) highlight areas with sufficient evidence allowing for integration into standard practice; (3) address methodological issues that restrict progress in this field; (4) identify major gaps to guide future research; and (5) specify priority research recommendations. Patient-centered outcomes were summarized within physical, psychological, social, and environmental domains, as well as for adherence to treatment, and health behaviors. Interventions to improve outcomes were evaluated for evidence of efficacy, although few interventions have been tested in long-term HCT survivors. Methodologic issues defined included lack of consistency in the selection of patient-centered outcome measures, along with the absence of a standard for timing, frequency, and mode of administration. Recommendations for HCT survivorship care included integration of annual screening of patient-centered outcomes, use of evidence-based practice guidelines, and provision of treatment summaries and survivorship care plans after HCT. Three priority research recommendations included the following: (1) design and test risk-targeted interventions with dose-intensity modulation matching the needs of HCT survivors with priority domains, including sexual dysfunction, fatigue, sleep disruption, nonadherence to medications and recommended health care, health behaviors including physical inactivity and healthy eating, and psychological dysfunction, with particular consideration of novel technologies to reach HCT survivors distant from their transplantation centers; (2) design a consensus-based methodologic framework for outcomes evaluation; and (3) evaluate and compare existing practices for integrating patient-centered outcome screening and interventions across HCT survivorship programs.

QUALIDADE DE VIDA NOS PRIMEIROS SEIS MESES PÓS-TRANSPLANTE DE CÉLULAS-TRONCO HEMATOPOÉTICAS

RESUMO Objetivo: avaliar a qualidade de vida dos pacientes adultos com câncer hematológico submetidos ao transplante de células-tronco hematopoéticas nos primeiros seis meses e comparar entre as modalidades de transplante. Método: estudo observacional, longitudinal, com 55 participantes, acompanhados nas etapas pré-transplante, pós 100 dias e pós 180 dias, em um hospital de ensino, referência no Brasil para este tratamento. Para avaliação foram utilizados dois instrumentos internacionais, ambos validados e traduzidos para a língua portuguesa (Brasil): Quality of Life Questionnarie-Core 30 e Functional Assessment Cancer Therapy-Bone Marrow Transplantation. Resultados: os resultados evidenciaram que a média de idade dos participantes foi de 36 anos, 65% (n=36) possuem diagnóstico de leucemia e 71% (n=39) foram submetidos ao transplante alogênico. Quanto ao instrumento Quality of Life Questionnarie-Core 30, foram resultados significantes a função social e fadiga, e no questionário Functional Assessment Cancer Therapy-Bone Marrow Transplantation os domínios bem-estar funcional e índice de avaliação de resultado do tratamento foram significantes entre a primeira e a segunda etapa. Conclusões: apesar do transplante ser um tratamento complexo e agressivo, percebe-se que os pacientes consideram sua qualidade de vida geral satisfatória ao longo do processo terapêutico. Os achados do estudo evidenciam que uma parcela significativa, 69% dos pacientes, recupera sua qualidade de vida após os primeiros seis meses de tratamento.

Efficacy of antithymocyte globulin for allogeneic hematopoietic cell transplantation: a systematic review and meta-analysis

The efficacy of rabbit antithymocyte globulin (ATG) for the prevention of graft-versus-host disease (GVHD) has been evaluated in several randomized control trials, but the results show some discrepancies. Therefore, we performed a systematic review and meta-analysis covering the latest RCTs including six trials (total 845 patients). The incidence of acute and chronic GVHD was significantly lower in the ATG arms (risk ratio, 0.75 and 0.54, respectively). No significant differences were found regarding overall survival, the incidence of relapse, and non-relapse mortality; however, the incidence of cytomegalovirus and Epstein-Barr virus reactivation increased (risk ratio, 1.25 and 1.33), and neutrophil engraftment was significantly delayed (median, 2.66 days). In conclusion, rabbit ATG should be beneficial as a GVHD prophylaxis in addition to conventional regimens, with close monitoring of virus reactivation and enough attention to delayed engraftment. Studies comparing the timing and dosage of ATG are essential to determine the suitable prophylactic regimens.
