Long-Term Recipient Health-Related Quality of Life and Donor-Recipient Relationship following Sibling Pediatric Hematopoietic Stem Cell Transplantation

Pediatric Hematopoietic Cell Transplantation: A Longitudinal Assessment of Health-Related Quality of Life of Pediatric Donors

Pediatric donors may be at increased risk of psychological and social challenges following hematopoietic cell transplantation (HCT). Through a retrospective chart review, we evaluated the health-related quality of life (HRQL) of pediatric donors over time and examined facilitators and barriers to implementing a longitudinal psychosocial assessment. Fifty-one pediatric donors (M = 10.7 years, SD = 3.7) completed an HRQL questionnaire across six time points (T1 to T6) from prior to donation to 2 years after. Change in mean scores was assessed using a linear mixed-effect model for repeated measures design. Facilitators and barriers to implementation were examined. HRQL of pediatric donors improved between T1 and T6 with significant change in physical, emotional, and overall functioning. Facilitators to retention included the support of a clinical coordinator. Barriers to implementation included the absence of infrastructure to maintain contact with pediatric and their families. HRQL of pediatric donors of HCT improved steadily over time. Pattern of results suggests a need to further explore factors that contribute to change across time. Development of a longitudinal standardized assessment protocol that can be prospectively and feasibly implemented is integral to supporting the well-being of this group.

Growth in the face of overwhelming pressure: A narrative review of sibling donor experiences in pediatric hematopoietic stem cell transplant

Sibling donation in pediatric hematopoietic stem cell transplant (HSCT) can be emotionally distressing for children, but may simultaneously evoke positive emotions, and has the potential to facilitate personal growth. We conducted a narrative review of sibling donor experiences, which included an analysis of psychosocial distress and post-traumatic growth (PTG). We searched the following databases: MEDLINE, CINAHL, PsycInfo, and SCOPUS. Search concepts used to develop key terms included HSCT, siblings, children, and psychosocial outcomes. Specific inclusion criteria included a) research articles published in English in peer-reviewed journals until September 2020, and b) reported trauma symptoms and PTG characteristics of sibling donation experiences. Four themes were identified: fear and anxiety related to HLA testing, overwhelming pressure to donate, guilt and blame when the ill child died, as well as emotional and physical isolation following donation. Sibling responses also included evidence of PTG, articulated as a deepened appreciation for life, closer relationships with the ill child and other family members, increased personal strength, and spiritual growth. These results highlight a critical need for future research approaches that further empower sibling donor voices, such as those found in participatory, arts-based methodologies.

Long-term survivors demonstrate superior quality of life after haploidentical stem cell transplantation to matched sibling donor transplantation

BACKGROUND

It has been well-documented that haplo-identical hematopoietic stem cell transplantation (HID-HSCT) can provide outcomes comparable to conventional matched sibling donor (MSD) HSCT, however, little is known about the effects on quality of life (QoL) in long-term survivors. This study is to investigate the differences in longitudinal performance of QoL between HID and MSD HSCT using a comprehensive assessment system.

METHODS

This prospective study enrolled consecutive patients who had received allogenic-HSCT (allo-HSCT) between January 2018 and December 2019 in our center. All patients were informed to complete QoL questionnaires including the Mos 36-Item Short-Form Health Survey (SF-36) and the Functional Assessment of Cancer Therapy Bone Marrow Transplant (FACT-BMT, version 4), using an online applet, before transplantation and at scheduled time points after transplantation. The linear mixed-effects model was used to analyze the variation trend of different dimensions of both SF-36 and FACT-BMT with different follow-up times.

RESULTS

Of the 425 participants, recipients of HID and MSD who survived more than 1 year (n = 230) were included in the final analysis of QoL (median age [range]: 36, [15, 66]). The 3 year overall survival (OS) of HID and MSD was 82.42% and 86.46%, respectively. QoL was assessed using both SF-36 and FACT-BMT and there was longitudinal recovery with clinical significance in the cohort. Compared to MSD-HSCT patients, HID-HSCT recipients demonstrated superior QoL performance in some subscales describing physical and mental wellness. Specifically, the difference in physical performance is more remarkable using FACT-BMT whereas that in mental wellness is more significant using SF36. In the subsequent stratified analysis, patients with a history of aGVHD or CMV reactivation demonstrated inferior QoL.

CONCLUSIONS

Long-term survivors of HID HSCT achieved better QoL in some sub-scales compared to MSD HSCT. In addition, SF-36 and FACT-BMT demonstrated different performance thus combination of both improved capacity of the evaluation system.

Suitability of haematopoietic cell donors: updated consensus recommendations from the WBMT standing committee on donor issues

The contribution of related donors to the globally rising number of allogeneic haematopoietic stem cell transplantations (HSCT) remains increasingly important, particularly because of the growing use of haploidentical HSCT. Compared with the strict recommendations on the suitability for unrelated donors, criteria for related donors allow for more discretion and vary between centres. In 2015, the donor outcome committee of the Worldwide Network for Blood and Marrow Transplantation (WBMT) proposed consensus recommendations of suitability criteria for paediatric and adult related donors. This Review provides updates and additions to these recommendations from a panel of experts with global representation, including the WBMT, the European Society for Blood and Marrow Transplantation donor outcome committee, the Center for International Blood and Marrow Transplant Research donor health and safety committee, the US National Marrow Donor Program, and the World Marrow Donor Association, after review of the current literature and guidelines. Sections on the suitability of related donors who would not qualify as unrelated donors have been updated. Sections on communicable diseases, clonal haematopoiesis of indeterminate potential, paediatric aspects including psychological issues, and reporting on serious adverse events have been added. The intention of this Review is to support decision making, with the goal of minimising the medical risk to the donor and protecting the recipient from transmissible diseases.

Late complications and quality of life assessment for survivors receiving allogeneic hematopoietic stem cell transplantation

PURPOSE

The survival rates of patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) have improved. However, HSCT can induce significant long-term complications. Therefore, we investigated the late complications and risk factors for quality of life (QOL) post-HSCT.

METHODS

We retrospectively analyzed 67 adult survivors over 2 years after HSCT between 2015 and 2018 at Ulsan University Hospital, Ulsan, Korea. The survey data including FACT-BMT, Hospital Anxiety and Depression Scale, and NCCN Distress Thermometer were collected as patient-reported outcomes using a tablet PC during a routine practice of survivorship clinic.

RESULTS

The median age was 46 years. The most common symptom was fatigue (80.6%). Younger age (< 60 years), acute lymphoblastic leukemia (ALL), chronic graft-versus-host disease (GVHD), and immunosuppressant use were significantly associated with worse QOL and depression. Additionally, younger survivors (< 60 years) showed significantly more fatigue and anxiety compared with elderly survivors (≥ 60 years). Female sex was significantly associated with lower physical well-being and higher distress than male sex.

CONCLUSION

Younger patients (< 60 years), female, ALL, chronic GVHD, and continuous immunosuppressant use were significant risk factors for worse QOL and depression. Hence, creating a more active survivorship care plan after HSCT, specifically for these patients, is required.
