Matched Marrow, Sibling Shadow: The Epidemiology, Experience, and Ethics of Sibling Donors of Stem Cells

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.

The experience of adults with sickle cell disease and their HLA-matched adult sibling donors after allogeneic hematopoietic stem cell transplantation

AIM

To provide a rich description and in-depth understanding of the recipient-donor allogeneic hematopoietic stem cell transplantation experience.

BACKGROUND

A stem cell transplant has a high likelihood of improving symptoms of sickle cell disease in adults. While studies have reported the transplant experiences of recipients and donors with haematological malignancies, no published reports have examined the experience of both adult recipients with sickle cell disease and their donors.

DESIGN

Exploratory qualitative descriptive analysis.

METHODS

We conducted individual interviews with 13 recipients and donors (eight males, five females) representing five recipient-donor dyads and one recipient-donor triad from one Midwest transplant centre between August 2017-February 2018. Interviews were digitally audio-recorded, transcribed verbatim and analysed using conventional content analysis.

FINDINGS

Five themes were identified: the downward spiral and a second chance; getting the monster off my back; difficult and manageable; it was worth it; and relating to the healthcare team.

CONCLUSIONS

The results provide a description and insights into the complex nature of the stem cell transplant experience in sickle cell disease from the perspectives of both recipients and donors.

IMPACT

Health provider awareness of recipient-donor experiences can contribute to family-centred care that supports the health and quality of life for both recipients and donors. This understanding promotes high quality clinical care and improved communications by taking into account the knowledge, values and informed preferences of recipients and donors and contributes to improved decision-making and clinical care. Future research can assess family experiences that support informed choice for potential transplant candidates.

Pilot Study of Educational Interventions for Pediatric Hematopoietic Stem Cell Sibling Donors to Increase Knowledge of Donation and Transplantation Procedures

Background

Siblings are frequently identified as a tissue match for patients with malignant and nonmalignant diseases and are selected to donate hematopoietic stem cells (HSC). Research on preparing siblings donors for stem cell donation is limited. Even after donation procedures are explained, siblings have been found to have difficulty understanding the information and may experience anxiety, particularly amongst younger donors. No prospective studies examining educational tools and transplant knowledge in sibling stem cell donors are currently available. This pilot study assessed donor comprehension of HSC donation procedures and compared knowledge prior to and post an educational intervention.

Methods

Assessment of baseline knowledge regarding HSC donation was assessed before and after the consent/information meeting with the medical team. Donors were then stratified into 2 groups by age. Donors aged 10 to 15 played an adapted version of the therapeutic game ShopTalk and donors aged 16 to 25 were provided a workbook designed for sibling stem cell donors. Assessment of knowledge was repeated 24 hours after the intervention.

Results

Participants included 17 siblings of pediatric transplant recipients, ages 10-25. Mean knowledge scores increased from 59.6% to 68.8% following the meeting with the medical provider and further increased to 88.5% after an educational intervention. Results suggest that education that provides information via a game or workbook increases knowledge in sibling donors.

Conclusion

Limited interactive educational material on stem cell donation is available for pediatric HSC donors. Additional visual and/or interactive information for sibling donors may increase knowledge and perhaps comfort with the donation process, beyond that which is provided by the medical teams. Providing detailed information about donation and discussion of procedures should be tailored to the individual learning style and supplemented with additional visual information.

Psychopathological Aspects in Childhood Hematopoietic Stem Cell Transplantation (HSCT): The Perception of Parents and Adolescents

Background: Data about psychosocial sequelae of childhood Hematopoietic Stem Cell Transplantation (HSCT) are limited and the association with a specific donor type or other medical factors is largely unknown (Chang et al., 2012). The aim of the present study was to compare the psychological aspects of pediatric HSCT survivors with healthy peers. A secondary aim was to detect whether parents and children differed in the perception of mental health status. The influence of medical factors on psychological status was also examined. Method: Thirty seven HSCT survivors (23 males) with a mean age of 14.4 years (SD = 3.03; range 8.16-18.33) were recruited. Twenty-six patients underwent an allogenic HSCT (matched unrelated donor, n = 20; matched sibling donor, n = 6) and 11 patients received an autologous HSCT. The children psychological aspects were assessed using the Youth Self Report (YSR) (Achenbach and Rescorla, 2001) and compared to a group of matched healthy peers. At the same time, parents were requested to complete the Child Behavior Checklist 6-18 (Achenbach and Rescorla, 2001). Medical and socio-demographic data were also collected. Results: HSCT survivors reported significantly higher levels of somatic complains (t27 = 3.14; p = 0.004; mean = 3.1) when compared to healthy peers (mean = 1.5). The parent CBCL scores on "child total competence" exceeded the normative clinical cutoff in 48.6% cases. Inter-rater agreement between parent and patient reports was present only in three scales: total competence score (K = 0.06, p = 0.002), somatic complaints (K = 0.21, p = 0.003) and attention problems (k = 0.13; p = 0.02). According to Ancova models, internalizing problems were more frequent in HSCT from family donors (F2 = 3.13; p = 0.06) or in the presence of acute complications (F1 = 11.95; p = 0.003). Conclusion: In contrast to the perception of parents, pediatric HSCT survivors reported good psychological health. However, they complained about more somatic problems as compared with healthy peers. Medical aspects such as donor source and the presence of acute complications should be taken into consideration for the psychological approach in order to improve pediatric HSCT survivor care.
