General health, symptom occurrence, and self-efficacy in adult survivors after allogeneic hematopoietic stem cell transplantation: a cross-sectional comparison between hospital care and home care

The effect of hematopoietic stem cell transplantation on patient-reported subjective oral dryness: a systematic review focusing on prevalence, severity and distress

OBJECTIVE

The aim of the present systematic review is to assess the prevalence and severity of and distress caused by xerostomia over time in adult hematopoietic stem cell transplantation (HSCT) recipients.

METHODS

PubMed, Embase, and the Cochrane Library were searched for papers published between January 2000 and May 2022. Clinical studies were included if patient-reported subjective oral dryness was reported in adult autologous or allogeneic HSCT recipients. Risk of bias was assessed according to a quality grading strategy published by the oral care study group of the MASCC/ISOO, resulting in a score between 0 (highest risk of bias) and 10 (lowest risk of bias). Separate analysis focused on autologous HSCT recipients, allogeneic HSCT recipients receiving a myeloablative conditioning (MAC), and those receiving a reduced intensity conditioning (RIC).

RESULTS

Searches yielded 1792 unique records; 22 studies met the inclusion criteria. The quality scores ranged between 1 and 7, with a median score of 4. The prevalence, severity, and distress of xerostomia increased shortly after HSCT. Severity of xerostomia in allogeneic MAC recipients was higher compared to allogeneic RIC recipients 2-5 months post-HSCT (mean difference: 18 points on 0-100 scale, 95% CI: 9-27); after 1-2 years, there was no significant difference anymore.

CONCLUSION

The prevalence of xerostomia in HSCT recipients is high in comparison to the general population. The severity of complaints is raised during the first year post-HSCT. The intensity of the conditioning plays a key role in the short-term development of xerostomia, while factors affecting the recovery in the long term remain largely unknown.

Symptom Burden and Recovery in the First Year After Allogeneic Hematopoietic Stem Cell Transplantation

BACKGROUND

Patients are affected by various symptoms after allogeneic hematopoietic stem cell transplantation (allo-HSCT) that can affect recovery. Research has mainly focused on symptom occurrence; thus, little is known about patients' overall symptom burden.

OBJECTIVE

The aim of this study was to examine patient-reported symptom burden in the first year after allo-HSCT and whether a high symptom burden 4 months after allo-HSCT predicts recovery, that is, general health and sick leave, 1 year after transplantation.

METHODS

Allo-HSCT patients aged 18 to 65 years were included (n = 189). Questionnaire data were collected on admission to the allo-HSCT unit, as well as 4 and 7 months and 1 year after allo-HSCT. Logistic regression evaluated relationships between demographic characteristics, chronic graft-versus-host disease, physical activity, and a high symptom burden.

RESULTS

Tiredness, susceptibility to infection, disinterest in sex, and physical weakness remained the most frequent symptoms, while distressing symptoms varied during the first year after allo-HSCT.Poor general health 1 year after allo-HSCT was associated with older age, low physical activity, and a high symptom burden 4 months after allo-HSCT. Full-time sick leave 1 year after allo-HSCT was associated with chronic graft-versus-host disease, low physical activity, and a high symptom burden 4 months after transplantation.

CONCLUSIONS

Experiencing a high symptom burden 4 months after allo-HSCT can affect recovery 1 year after transplantation. Furthermore, low physical activity 4 months after allo-HSCT can predict both general health and sick leave 1 year after transplantation.

IMPLICATIONS FOR PRACTICE

Repeated symptom assessment, including experienced distress, is central for reducing overall symptom burden and supporting recovery after allo-HSCT.

Hospital nurses' experiences of assessing health status changes in stem-cell transplanted patients in home care: A qualitative study

AIMS AND OBJECTIVES

To explore hospital nurses' experience assessing changes in the health status of stem-cell transplanted patients in home care (HC).

BACKGROUND

Stem-cell transplanted patients in HC are treated at home instead of in hospital wards. Hospital nurses visit patients daily and play a key role in assessing the patients' health status. Previous studies on HC for stem-cell transplanted patients focus mainly on safety in HC versus hospital care. No studies regarding nurses' experience assessing patients' health status at home when patients undergo stem-cell transplantation were found.

DESIGN

Qualitative study with an explorative design.

METHODS

Data were collected via 14 individual semi-structured interviews with hospital nurses working with stem-cell transplanted patients in HC. Data were analysed using systematic text condensation. The reporting of the study was guided by the COREQ checklist.

RESULTS

Three categories emerged from the data analysis: 1) Effective communication and clinical intuition enhances the assessment of patients' general health condition; 2) It is challenging to rely on one's own judgment in remote assessment; and 3) There are key facilitators in performing remote clinical assessments.

CONCLUSIONS

Effective communication and clinical intuition enhanced the assessment of patients' general health conditions. The lack of physical presence during remote assessments made using clinical intuition in the assessment process difficult. Experience with hematopoietic stem-cell transplantation was seen as important to facilitate accurate remote clinical assessments.

RELEVANCE TO CLINICAL PRACTICE

Nurses with responsibility for hospital at-home telephone care should receive training in remote communication and should shadow hospital at-home nurses during in home visits to gain experience assessing patients' health status. Telehealth aspects such as videoconferencing and remote patient monitoring should be considered for more accurate remote assessment. This could potentially result in more effective assessments and reduced readmissions and could promote nurses' confidence in their assessments.

Important factors associated with sick leave after allogeneic haematopoietic stem cell transplantation-a 1-year prospective study

Purpose

This study examines sick leave (SL) and factors associated with full-time SL 1 year after allogeneic haematopoietic stem cell transplantation (allo-HSCT) in patients of working age from 2009 to 2016 (n = 122).

Methods

Questionnaire data were collected on admission to the allo-HSCT unit, at 7 months and 1 year after allo-HSCT. Associations between factors and SL were analysed using logistic regression analyses.

Results

One year after allo-HSCT, 76% of participants were on SL, with 36% on full-time SL. In univariable analyses, chronic graft-versus-host-disease (cGvHD) (OR 3.07; 95% CI 1.34–7.07; p = 0.01), having symptoms of depression at 7 months (OR 4.81; 95% CI 1.69–13.69; p = 0.00) and low levels of vocational satisfaction at 7 months after treatment (OR 3.27; 95% CI 1.27–8.41; p = 0.01) were associated with full-time SL 1 year after allo-HSCT. cGvHD (OR 3.43; 95% CI 1.35–8.73; p = 0.01) and having symptoms of depression at 7 months after allo-HSCT (OR 3.37; 95% CI 1.2–11.58; p = 0.02) remained significant in multivariable analysis.

Conclusion

The majority of allo-HSCT survivors were on SL 1 year after treatment, and cGvHD, low vocational satisfaction and depressive symptoms were associated with full-time SL 1 year after allo-HSCT.

Implications for Cancer Survivors

Healthcare professionals need to be observant of and manage the consequences of cGvHD and patients’ symptoms of depression in order to support them appropriately in their return-to-work process.

Implementing a Feasible Exercise Programme in an Allogeneic Haematopoietic Stem Cell Transplantation Setting-Impact on Physical Activity and Fatigue

Physical exercise for patients treated with allogeneic haematopoietic stem cell transplantation (allo-HSCT) has shown positive effects on the quality of life and fatigue in experimental trials. However, there is a need for longitudinal evaluation of exercise programmes implemented in a real-world clinical setting. The aim of this prospective study was to evaluate the impact of an exercise programme introduced before allo-HSCT on physical activity and fatigue before, during and after in-patient care. A structured exercise programme, including strength and endurance exercises, was implemented at a Swedish university hospital four weeks before transplantation, continuing during in-patient care and after discharge. Between March 2016 and May 2018, 67 adult patients, 33 women and 34 men with a mean age of 55.5 years participated. Fatigue was measured by the Multidimensional Fatigue Inventory at four time points. The patients documented their exercises on a checklist each week during the entire study period. The fatigue trajectory differed between various sub-groups, thus individualized supervision and support to maintain motivation is needed. In conclusion, a structured yet realistic exercise programme before admission is beneficial for allo-HSCT patients in order to reduce fatigue and prepare them for transplantation both physically and mentally.

Self-efficacy for symptom management in the acute phase of hematopoietic stem cell transplant: A pilot study

PURPOSE

Hematopoietic stem cell transplant (HSCT) is an intensive treatment associated with distressing treatment and disease-related symptoms that affect patient outcomes such as functional status and quality of life. Self-efficacy for symptom management (SESM) is a person's belief in their ability to perform behaviors to prevent and relieve symptoms. Presence of SESM can impact symptom distress and functional status. This study describes the changes over time and relationships among SESM, symptom distress, and physical functional status in adults during the acute phase of HSCT.

METHODS

Patients (n = 40) completed measures of symptom distress, SESM, and physical function at time points prior to and at days 7, 15 and 30 post-transplant. Clinical outcomes were length of stay and number of readmissions.

RESULTS

Symptom distress, physical function, and SESM changed significantly over time. There was a significant negative relationship between symptom distress and physical function and between symptom distress and SESM at all points. The lowest levels of SESM and physical function were at day 7 when symptom distress was highest. Symptom distress was a moderator for the relationship between physical function and SESM at day 15.

CONCLUSION

This was the first study to examine SESM in the acute phase of HSCT. Higher SESM was associated with fewer symptoms and increased physical function. Less symptom distress was associated with higher physical function and confidence to manage symptoms. These findings provide the basis for development of patient-centered interventions to enhance SESM when symptoms are at their highest immediately after HSCT.

The importance of graft cell composition in outcome after allogeneic stem cell transplantation in patients with malignant disease

BACKGROUND

Graft-versus-host disease (GVHD) and relapse remain majobstacles ftreatment success in allogeneic hematopoietic stem cell transplantation (HSCT). In the present study, we evaluated the immune cell profile of the graft to outcome after HSCT.

STUDY DESIGN AND METHOD

Flow cytometry data of graft cell subsets [CD34⁺ , CD3⁺ , CD19⁺ , CD4⁺ , CD8⁺ , CD3-CD56⁺ CD16⁺ , CD4⁺ CD127^low CD25^high ] from G-CSF primed peripheral blood stem cell (PBSC) donors was collected retrospectively from 299 patients with hematological malignancies undergoing HSCT between 2006 and 2013. The association to overall survival, transplant-related mortality (TRM), GVHD and probability of relapse was analyzed. Patients outcome from HLA-identical sibling (Sib) (n = 97) and unrelated donors (URD) (n = 202) were analyzed separately as all URD patients received anti-thymocyte globulin (ATG).

RESULTS

Five-year overall survival was similar in the two cohorts (68% (Sib) vs 65% (URD)). The relapse incidence was significantly lower in the Sib cohort (24% vs 35%, P = 0.04). Multivariate analysis in the URD group revealed an association between a higher CD8⁺ dose and less relapse (HR, 0.94; 95%CI, 0.90-0.98; P = 0.006) as well as an association between higher CD34⁺ dose and both higher TRM (HR, 1.09; 95%CI, 1.02-1.20; P = 0.02) and relapse (HR, 1.09; 95%CI, 1.01-1.17; P = 0.025). The Sib analysis showed an association between a higher graft CD19⁺ dose and more severe acute GVHD (HR, 1,09; 95%CI, 1.03-1.15; P = 0.003) and TRM (HR, 1.09; 95%CI, 1.01-1.17; P = 0.036). In addition, a higher CD4⁺ graft content was associated to an increased risk for chronic GVHD (HR, 1.02; 95%CI 1.00-1.04; P = 0.06).

CONCLUSION

These data indicate an importance of PBSC dongraft composition in patients with a hematological malignancy.

The Meaning of Self-efficacy for Symptom Management in the Acute Phase of Hematopoietic Stem Cell Transplantation

BACKGROUND

Hematopoietic stem cell transplantation (HSCT) is an intensive treatment that offers the potential for longer life or cure for some types of cancer. Hematopoietic stem cell transplant is associated with decreased quality of life and functional status and distressing symptoms. Self-efficacy for symptom management (SESM) is a person's belief in his/her ability to implement behaviors to manage these symptoms. Presence of SESM can affect symptom distress, healthcare utilization, and posttransplantation outcomes.

OBJECTIVE

The aim of this study was to explore the meaning of SESM in adults during the acute phase of HSCT.

METHODS

Interviews were conducted before and at 30 days after transplantation. Descriptive thematic analysis was performed on verbatim interview transcripts.

RESULTS

Themes of confidence, being responsible, and caring for mind, body, and spirit were identified, with subthemes of self-confidence, confidence in others, confidence and symptom level, vigilance, self-advocacy, and normalcy. Participants reported having high SESM before transplantation and having much less or no SESM when symptom distress was the most severe.

CONCLUSIONS

This is the first study to examine the patient's perspective of self-efficacy in the acute phase of HSCT. This contributes to existing literature on the concept of symptom management and expands nursing knowledge of SESM in patients undergoing HSCT.

IMPLICATIONS FOR PRACTICE

Nurses can assess SESM before transplantation and implement interventions to enhance SESM when symptoms are at their most distressing after HSCT. The findings from this study can provide the basis for creating behavioral interventions to enhance self-efficacy for symptom management in HSCT patients.

Steps to Enhance Early Recovery After Hematopoietic Stem Cell Transplantation: Lessons Learned From a Physical Activity Feasibility Study

AIMS

This pilot study tested and refined a free-living physical activity intervention. The investigators evaluated the acceptability and feasibility of the intervention after hematopoietic stem cell transplantation and determined preliminary effects on physical activity, fatigue, muscle strength, functional ability, and quality of life.

DESIGN

This pilot study used a 1-group, pretest-posttest design.

METHODS

The free-living physical activity intervention consisted of an education component and 6 weeks of gradually increasing physical activity after discharge from the hospital. The intervention was designed to increase steps by 10% weekly. Subjects were assessed before transplantation and during the seventh week after discharge from the hospital after completing the intervention. Pretest-posttest scores were analyzed with paired t tests.

RESULTS

Subject wore the physical activity tracker for an average of 38 of 42 days and met their physical activity goals 57% of the time. Subjects reported significantly less physical fatigue after the free-living physical activity intervention compared with baseline (P = .05). Improvements in quality of life approached significance (P = .06).

CONCLUSION

The findings demonstrate that the free-living physical activity intervention implemented during the very early recovery period after transplantation is feasible and acceptable. The intervention potentially reduces fatigue and improves quality of life. The positive results must be interpreted cautiously given the pilot nature of the study. The evidence supports continued investigation.

Strength Training to Enhance Early Recovery after Hematopoietic Stem Cell Transplantation

Intensive cancer treatment followed by hematopoietic stem cell transplantation (HCT) results in moderate to severe fatigue and physical inactivity, leading to diminished functional ability. The purpose of this study was to determine the efficacy of an exercise intervention, strength training to enhance early recovery (STEER), on physical activity, fatigue, muscle strength, functional ability, and quality of life after HCT. This single-blind, randomized clinical trial compared strength training (n = 33) to usual care plus attention control with health education (UC + AC with HE) (n = 34). Subjects were stratified by type of transplantation and age. STEER consisted of a comprehensive program of progressive resistance introduced during hospitalization and continued for 6 weeks after hospital discharge. Fatigue, physical activity, muscle strength, functional ability, and quality of life were assessed before HCT hospital admission and after intervention completion. Data were analyzed using split-plot analysis of variance. Significant time × group interactions effects were noted for fatigue (P = .04). The STEER group reported improvement in fatigue from baseline to after intervention whereas the UC + AC with HE group reported worsened fatigue from baseline to after intervention. Time (P < .001) and group effects (P = .05) were observed for physical activity. Physical activity declined from baseline to 6 weeks after hospitalization. The STEER group was more physically active. Functional ability tests (timed stair climb and timed up and go) resulted in a significant interaction effect (P = .03 and P = .05, respectively). Subjects in the UC + AC with HE group were significantly slower on both tests baseline to after intervention, whereas the STEER group's time remained stable. The STEER group completed both tests faster than the UC + AC with HE group after intervention. Study findings support the use of STEER after intensive cancer treatment and HCT. Strength training demonstrated positive effects on fatigue, physical activity, muscle strength, and functional ability. The exact recovery patterns between groups and over time varied; the STEER group either improved or maintained their status from baseline to after intervention (6 weeks after hospital discharge) whereas the health education group generally declined over time or did not change.

Towards in vivo amplification: Overcoming hurdles in the use of hematopoietic stem cells in transplantation and gene therapy

With the advent of safer and more efficient gene transfer methods, gene therapy has become a viable solution for many inherited and acquired disorders. Hematopoietic stem cells (HSCs) are a prime cell compartment for gene therapy aimed at correcting blood-based disorders, as well as those amenable to metabolic outcomes that can effect cross-correction. While some resounding clinical successes have recently been demonstrated, ample room remains to increase the therapeutic output from HSC-directed gene therapy. In vivo amplification of therapeutic cells is one avenue to achieve enhanced gene product delivery. To date, attempts have been made to provide HSCs with resistance to cytotoxic drugs, to include drug-inducible growth modules specific to HSCs, and to increase the engraftment potential of transduced HSCs. This review aims to summarize amplification strategies that have been developed and tested and to discuss their advantages along with barriers faced towards their clinical adaptation. In addition, next-generation strategies to circumvent current limitations of specific amplification schemas are discussed.
