The experience and preparation of pediatric sibling bone marrow donors

Evaluation of Children with Malignancies for Blood and Marrow Transplantation: A Report from the ASTCT Committee on Practice Guidelines

Evaluation of a candidate for hematopoietic cell transplantation (HCT) is a complex process with substantial intercenter variability. Although literature providing guidance for evaluating the eligibility of adults is well established, similar guidance for children is lacking. To address gaps between adult recommendations and the specific needs of children, we convened a panel of pediatric HCT experts from a wide geographic range of American Society of Transplantation and Cellular Therapy (ASTCT) member institutions to offer recommendations for pediatric-focused pre-HCT evaluation. In this report from the ASTCT Committee on Practice Guidelines, we present a practical framework for evaluating children with malignancies who are candidates for HCT. We also highlight key differences from adults and emphasize areas of unmet need that require additional research to delineate best practices.

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.

Transplant center practices for psychosocial assessment and management of pediatric hematopoietic stem cell donors

Understanding the potential emotional and psychological risks of pediatric sibling HSC donation is an area of research that remains in its infancy. A cross-sectional survey was distributed electronically to directors at all CIBMTR and EBMT centers to describe current transplant center practices for obtaining assent, preparation for the physical/emotional experiences of donation, and monitoring the post-donation well-being of pediatric donors (<18 years of age). Respondents were 45/91 (49%) and 66/144 (46%) of CIBMTR and EBMT centers, respectively. Although 78% of centers reported having a mechanism in place to ensure donor free assent, centers also reported only limited assessment of psychosocial suitability to manage the emotional risks of donation. More than half of centers reported no psychosocial follow-up assessment post-donation. Few centers have policies in place to address donor psychological needs. Future investigations should include medical and psychosocial outcomes following full integration of comprehensive psychosocial screening and surveillance of pediatric donors.

Donor Selection for Allogenic Hemopoietic Stem Cell Transplantation: Clinical and Ethical Considerations

Allogenic hematopoietic progenitor cell transplantation (allo-HSCT) is an established treatment for many diseases. Stem cells may be obtained from different sources: mobilized peripheral blood stem cells, bone marrow, and umbilical cord blood. The progress in transplantation procedures, the establishment of experienced transplant centres, and the creation of unrelated adult donor registries and cord blood banks gave those without an human leucocyte antigen- (HLA-) identical sibling donor the opportunity to find a donor and cord blood units worldwide. HSCT imposes operative cautions so that the entire donation/transplantation procedure is safe for both donors and recipients; it carries with it significant clinical, moral, and ethical concerns, mostly when donors are minors. The following points have been stressed: the donation should be excluded when excessive risks for the donor are reasonable, donors must receive an accurate information regarding eventual adverse events and health burden for the donors themselves, a valid consent is required, and the recipient's risks must be outweighed by the expected benefits. The issue of conflict of interest, when the same physician has the responsibility for both donor selection and recipient care, is highlighted as well as the need of an adequate insurance protection for all the parties involved.

Family Strategies to Support Siblings of Pediatric Hematopoietic Stem Cell Transplant Patients

OBJECTIVE

To describe the strategies families report using to address the needs and concerns of siblings of children, adolescents, and young adults undergoing hematopoietic stem cell transplant (HSCT).

METHODS

A secondary semantic analysis was conducted of 86 qualitative interviews with family members of children, adolescents, and young adults undergoing HSCT at 4 HSCT centers and supplemented with a primary analysis of 38 additional targeted qualitative interviews (23 family members, 15 health care professionals) conducted at the primary center. Analyses focused on sibling issues and the strategies families use to address these issues.

RESULTS

The sibling issues identified included: (1) feeling negative effects of separation from the patient and caregiver(s); (2) experiencing difficult emotions; (3) being faced with additional responsibilities or burdens; (4) lacking information; and (5) feeling excluded. Families and health care providers reported the following strategies to support siblings: (1) sharing information; (2) using social support and help offered by family or friends; (3) taking siblings to the hospital; (4) communicating virtually; (5) providing special events or gifts or quality time for siblings; (6) offering siblings a defined role to help the family during the transplant process; (7) switching between parents at the hospital; (8) keeping the sibling's life constant; and, (9) arranging sibling meetings with a certified child life specialist or school counselor.

CONCLUSIONS

Understanding the above strategies and sharing them with other families in similar situations can begin to address sibling issues during HSCT and can improve hospital-based, family-centered care efforts.

Unmet needs of siblings of pediatric stem cell transplant recipients

BACKGROUND AND OBJECTIVES

In 2010, the Bioethics Committee of the American Academy of Pediatrics issued recommendations that pediatric hematopoietic stem cell donors should have an independent advocate. Formulating appropriate guidelines is hindered by the lack of prospective empirical evidence from families about the experience of siblings during typing and donation. Our aim was to provide these data.

METHODS

Families with a child scheduled to undergo hematopoietic stem cell transplant were recruited. All family members, including children aged 9 to 22 years, were eligible. Qualitative interviews were conducted within 3 time periods: pretransplant, 6 to 8, and 9 to 11 months posttransplant. Quantitative scales assessing decision satisfaction and regret were administered at time 2.

RESULTS

Thirty-three families were interviewed. Of the 119 family members, 76% perceived there was no choice in the decision to HLA-type siblings; 77% perceived no choice in sibling donation; 86% had no concerns about typing other than needle sticks; and 64% had no concerns about donation. Common concerns raised were dislike of needle sticks (19%), stress before typing results (14%), and fear of donation (15%). Posttransplantation, 33% of donors wished they had been given more information; 56% of donors stated they benefited from donation. Only 1 donor expressed regret posttransplant.

CONCLUSIONS

Most family members did not view sibling typing and donation as a choice, were positive about the experience, and did not express regrets. We recommend education for all siblings before typing, comprehensive education for the donor by a health care provider pretransplant, and systematic donor follow-up after transplantation.

Immediate and long-term somatic effects, and health-related quality of life of BM donation during early childhood. A single-center report in 210 pediatric donors

Since 1968, when Leiden undertook the first successful European pediatric BM transplantation with a 7-year-old sibling donor, more than 300 young children have donated BM in our unit. We first retrospectively studied a cohort of 210 donors, younger than 13 years at donation, to survey procedures of donor eligibility and study immediate effects of BM donation. We then performed a long-term follow-up (FU) and health-related quality of life (HRQoL) study. Despite documentation of previous medical conditions, no child was declared unfit to donate. We found that iron deficiency anemia or low-iron stores in BM did not result in treatment or extended FU. Harvest volumes exceeded 15 mL/kg in 65% of donors, with more than half requiring allogeneic blood transfusions. Donors had no structured FU after their first post-donation control. In this study, 25% of donors reported at least one somatic complaint at long-term FU. Finally long-term HRQoL revealed high scores in most subdomains (representing a higher QoL), compared to norm groups. These results indicate the need for development of (inter)national guidelines for pediatric stem cell donor care management.

Shared decision-making in pediatric allogeneic blood and marrow transplantation: what if there is no decision to make?

INTRODUCTION

Shared decision-making between health care professionals, patients, parents, and guardians is widely recommended today. However, it is unclear what happens when collaborative language is used by physicians in clinical situations for which patients and parents/guardians believe there is no decision to be made.

METHODS

We conducted a qualitative study of decision-making for pediatric allogeneic blood and marrow transplantation by interviewing patients, parents, grandparents, donor siblings, and nondonor children after the decision to proceed to transplant but before the transplantation. Each interview was audio recorded, transcribed, and coded for major themes.

RESULTS

In total, 107 members of 30 families at four sites were interviewed, including 15 patients, 22 mothers, 2 stepmothers, 1 grandmother, 19 fathers, 3 stepfathers, 1 grandfather, 13 sibling donors, and 31 nondonor children (siblings, half-siblings, and cousins). In all, 81% of parents/guardians, 73% of patients, 31% of donors, and 29% of other children reported there was no decision to be made. Almost all (88%) parents/guardians indicated that the physician's recommendation was a large determinant in their agreement to go forward with the transplantation. All parents/guardians reported that "agreeing to a plan" was a better description of what their consent entailed.

CONCLUSIONS

To be respectful of patients and parents/guardians, we suggest that "agreeing to a plan" may be a better description for what parents/guardians must consider when the alternative to a transplantation is likely death. In this clinical context, the shared decision-making model with a focus on "a decision to be made" may be misleading.

The management of the sibling hematopoietic stem cell donor

Hematopoietic stem cell transplants are procedures with curative potential for patients with diseased, damaged, or absent stem cells. Because a sibling has the best chance of immunocompatibility with one in need of a transplant, siblings are the most suitable donors of stem cells. However, when siblings are stem cell donors, various ethical issues arise concerning the risks and benefits to the pediatric donor. Because of the critical and potential rapid deterioration of the recipient's condition, the needs of the sibling donor may be overlooked. This potential lack of advocacy for the pediatric sibling donor creates a role for the primary care provider to assess the child's physical and psychological ability to undergo the donation procedure, examine the ethical issues in choosing to use the pediatric sibling as the stem cell donor, prepare the child for the procedure, and follow-up with the sibling donor once the procedure is completed.

Ethical issues in bone marrow transplantation in children

In the 50 years since the first successful human bone marrow transplant (BMT) was performed in 1959, BMT has become the optimal therapy for a wide variety of life-threatening paediatric haematological, immunological and genetic disorders. Unfortunately, while BMT generally provides the only possibility of cure for such afflicted children, few (25%) have a matched sibling available, and suitably matched unrelated donors are often not identified for many children in need of BMT. And even where BMT is possible, treatment is complex and arduous and associated with significant mortality and morbidity. The issues raised when either or both the donor and recipient are children and lack the capacity to make informed and rational decisions relating to BMT pose great challenges for all involved. This paper examines some of the ethical dilemmas that confront patients, families and medical practitioners when considering bone marrow transplantation in a child.

Bone Marrow Donation from the Perspective of Sibling Donors

This study aimed to characterize the sociodemographic profile of sibling bone marrow donors and to describe how they perceive the donation. This was a descriptive, exploratory and longitudinal study. Participants were 20 related bone marrow donors, between 18 and 42 years of age (mean=30.5 years, sd=7.47). Interviews were held before and immediately after the donation. Sociodemographic data were subject to descriptive statistical analysis and qualitative data to categorical content analysis. In the interviews held before the donation, stressor events were the sibling’s disease and treatment and the responsibility of being the donors. During the interviews after the donation, the following were mentioned: anxiety on the day before and on the day of the donation, pain the following day, and acknowledgement of the health team’s support as a facilitator of the donation process. In view of the findings, it is important for the team to outline intervention strategies to meet to the donors’ specific needs.

Psychosocial assessment prior to pediatric transplantation: a review and summary of key considerations

Prior to listing for transplantation, patients participate in a comprehensive, multidisciplinary evaluation. One component of this process, incorporated by the vast majority of transplant centers, is a psychosocial assessment conducted by a mental health professional. The primary objectives of a pre-transplant psychosocial assessment are to identify risk factors for difficulty adjusting post-transplant as well as behaviors that may compromise transplantation outcomes. This paper aims to provide a summary of key considerations for pediatric transplant teams describing what this assessment might include, when it should be performed, training requirements for the evaluators, how results of the evaluation might best be utilized and suggestions for optimal patient preparation. Our findings suggest that the evaluation, which can be conducted by a variety of professionals, should include assessment of patient knowledge and motivation for transplant, mental health and substance abuse history, presence or absence of family and social support, availability of financial resources, past history of treatment adherence, and the quality of the family's relationship with the transplant team. Repeat assessments and utilizing the initial evaluation for outcome assessment should be considered. Finally, the evaluation offers a unique opportunity for better preparing patients and families for transplantation.

Psychological effects of hematopoietic SCT on pediatric patients, siblings and parents: a review

Although hematopoietic SCT (HSCT) has become standard therapy for many life-threatening disorders of childhood, there is little research on the psychosocial ramifications of HSCT on patients, siblings and parents. Pediatric patients experience numerous psychological reactions throughout hospitalization, the procedure and recovery process: anxiety, depression, behavioral and social problems, and post-traumatic stress reactions. Similarly, sibling donors are at risk of developing emotional disturbances such as post-traumatic stress reactions, anxiety and low self-esteem. Parental distress, anxiety and depression levels are often increased as a result of their child undergoing the HSCT process. The distress and anxiety may be even greater for parents whose healthy child also becomes part of the HSCT process through donating their marrow. Thus, it is critical to develop interventions for pediatric patients and their families. There is, however, minimal research of interventions aimed at decreasing distress and improving emotional and psychosocial functioning for children undergoing HSCT, siblings and parents. Cognitive-behavioral interventions are the most researched treatment approaches for children with cancer and chronic illness and these are promising in improving emotional distress, compliance with treatment and behavioral problems associated with HSCT. Appropriate arenas in which pediatric patient interventions may focus include social skills and emotional well-being. Familial interventions that aim to enhance protective factors, improve communication, and decrease parental anxiety and depression are crucial, and cancer-specific interventions may serve as a template for the development of HSCT-specific interventions.

Children as hematopoietic stem cell donors

In the past half-century, hematopoietic stem cell transplantation has become standard treatment for a variety of diseases in children and adults, including selected hematologic malignancies, immunodeficiencies, hemoglobinopathies, bone marrow failure syndromes, and congenital metabolic disorders. There are 3 sources of allogeneic hematopoietic stem cells: bone marrow, peripheral blood, and umbilical cord blood; each has its own benefits and risks. Children often serve as hematopoietic stem cell donors, most commonly for their siblings. HLA-matched biological siblings are generally preferred as donors because of reduced risks of transplant-related complications as compared with unrelated donors. This statement includes a discussion of the ethical considerations regarding minors serving as stem cell donors, using the traditional benefit/burden calculation from the perspectives of both the donor and the recipient. The statement also includes an examination of the circumstances under which a minor may ethically participate as a hematopoietic stem cell donor, how the risks can be minimized, what the informed-consent process should entail, the role for a donor advocate (or some similar mechanism), and other ethical concerns. The American Academy of Pediatrics holds that minors can ethically serve as stem cell donors when specific criteria are fulfilled.

Multiple BM harvests in pediatric donors for thalassemic siblings: safety, efficacy and ethical issues

Allogeneic BMT represents the only chance of cure for beta-thalassemia. Occasionally, two affected individuals from the same family share a matched healthy sibling. Moreover, a high incidence of transplant rejection is still observed in Pesaro class III patients, requiring a second BMT procedure. In these settings, one option is to perform a second BM harvest from the same donor. Although BM harvest is a safe procedure in children, ethical issues concerning this invasive practice still arise. Here, we describe our series of seven pediatric, healthy donors, who donated BM more than once in favor of their beta-thalassemic HLA-identical siblings between June 2005 and January 2008. Three donors donated BM twice to two affected siblings and four donors donated twice for the same sibling following graft rejection of the first BMT. All donors tolerated the procedures well and no relevant side effects occurred. There was no significant difference between the two harvests concerning cell yield and time to engraftment. Our experience shows that for pediatric donors, a second BM donation is safe and feasible and good cellularity can be obtained. We suggest that a second harvest of a pediatric donor can be performed when a strong indication for BMT exists.

Repercussões psicológicas do transplante de medula óssea no doador relacionado

O desenvolvimento do transplante de medula óssea (TMO), nas últimas décadas, permitiu o tratamento de doenças que antes eram invariavelmente fatais. Dentre os tipos de transplante realizados, o alogênico exige a participação ativa de um membro familiar, em geral, o irmão, que arca com o encargo da doação. O objetivo do presente estudo é analisar as repercussões psicológicas dessa doação nos doadores relacionados. A amostra foi composta por dez doadores, vinculados à Unidade de TMO do HCFMRP-USP, avaliados antes e após a doação. Os instrumentos utilizados foram: roteiro de entrevista, escalas e técnicas projetivas. Os resultados demonstraram que o nível de ansiedade dos sujeitos se encontrava dentro do esperado, porém foram constatados sintomas de estresse. Afirmaram terem ficado ansiosos e relataram dor no momento pós-doação, mas acreditam que esta foi mais fácil do que imaginaram. Finalmente, em relação aos dados das técnicas projetivas, constatou-se uma alta suscetibilidade emocional, indícios de sugestionabilidade e dependência.

Supporting Siblings Through the Pediatric Bone Marrow Transplant Trajectory

When a child undergoes bone marrow transplant (BMT), the entire family is affected by the demands of the transitions encountered throughout the BMT experience. Although there is a growing body of knowledge on how healthy siblings adjust to the BMT experience, there is still much to be learned. Part of a larger study aimed at detailing healthy siblings' lived experiences of BMT, this article presents findings specific to one of the study's objectives that focused on understanding siblings' perspectives of how nurses and other health professionals can best support siblings throughout the BMT trajectory. A qualitative research study guided by the philosophy of hermeneutic phenomenology was conducted. Eight siblings of pediatric BMT recipients were recruited. Semistructured, open-ended interviews, demographic data, and field notes were the primary sources of data. Interview transcripts were analyzed and interpreted using van Manen's approach. Seven themes emerged: (1) include me in the definition of "family," (2) be caring, (3) share information with me, (4) give me choices, (5) help me share my feelings, (6) provide opportunities for me to meet my peers, and (7) create a healthy hospital environment. Findings showed that siblings have definite thoughts about how nurses and other health professionals should support them, but their support needs are not being met.

An Interruption in Family Life: Siblings' Lived Experience as They Transition Through the Pediatric Bone Marrow Transplant Trajectory

PURPOSE/OBJECTIVES

To arrive at an understanding of the lived experience of healthy donor and nondonor siblings as they transition through the bone marrow transplantation (BMT) trajectory.

RESEARCH APPROACH

Qualitative study guided by the philosophy of hermeneutic phenomenology.

SETTING

Participants' homes or the investigator's university or hospital office.

PARTICIPANTS

Eight siblings of pediatric BMT recipients were recruited based on their knowledge of the experience of transitioning through the BMT trajectory.

METHODOLOGIC APPROACH

Data were collected by semistructured, open-ended interviews; demographic forms; and field notes during a period of six months. Data analysis occurred concurrently with data collection. Thematic statements were isolated using Van Manen's selective highlighting approach. Interviews were reviewed repeatedly for significant statements.

MAIN RESEARCH VARIABLE

Siblings' lived experience of the BMT trajectory.

FINDINGS

Interruption in family life emerged as the essence of siblings' lived experience. Four themes supported this essence: life goes on, feeling more or less a part of a family, faith in God that things will be okay, and feelings around families.

CONCLUSIONS

Hermeneutic phenomenologic research increases understanding of what being a sibling of a pediatric BMT recipient means. This study is one of the few that have afforded siblings the opportunity to speak about what is important to them.

INTERPRETATION

Findings from this study provide insight into how siblings live and cope throughout the BMT trajectory and will guide nurses as they seek to provide more sensitive and comprehensive care.

Hematopoietic stem cell donation in children: a review of the sibling donor experience

Hematopoietic Stem Cell Transplant (HSCT) represents the second most frequent major organ transplant in the United States. Compared with other family members, siblings are more likely to be immunologically matched with the recipient and therefore are often the most suitable donors. Due to a dearth of information on the positive and adverse effects of HSCT on pediatric sibling donors, we sought to examine available data. Eight published reports assessing the pediatric sibling donor experience were identified in the literature. Studies were predominately small (n < 44) and cross-sectional. Results suggest a range of psychological distress responses with higher distress in pediatric donor than non-donor siblings. Recommendations include future longitudinal research on sibling donor psychosocial adjustment, identification of sibling donors at high risk for maladaptive responses, and development of educational and psychosocial interventions for this overlooked pediatric population.

Weighing the risks of G-CSF administration, leukopheresis, and standard marrow harvest: ethical and safety considerations for normal pediatric hematopoietic cell donors

BACKGROUND

Granulocyte colony stimulating factor (G-CSF) is used for collection of hematopoietic cells in most adult and a smaller but significant percentage of pediatric normal donor harvests. Short and long-term risks of G-CSF administration and leukopheresis are not well understood in the pediatric population.

PROCEDURE

Literature review including observations from the IBMTR, NMDP, EBMT, German Donor Registry, and the authors' work.

RESULTS

G-CSF causes temporary discomfort in a minority of younger donors. Rare serious side effects of G-CSF have yet to be reported in children. To date, an increase in hematological malignancies after short-term G-CSF use has not been detected in adult donors and no cases have been reported in children. Reported complications of leukopheresis in children are rare and minor, but donors <20 kg may be exposed to allogeneic blood products. Pediatric aged donors vary widely in their ability to assent or consent to the risks of a donation procedure. There are key regulations and ethical imperitives, which must be addressed in deciding which donation procedures are appropriate for minors.

CONCLUSIONS

While short term administration of G-CSF and leukopheresis appear to be safe and effective procedures when used to assist in collection of a hematopoietic cell graft from a normal pediatric donor, institutions adding or substituting one or both of these procedures for standard marrow donation must decide whether the donor should be considered a research subject, and if so, whether the new procedures are a minor increase over minimal risk. Because these procedures are being performed on and off study at many pediatric centers, a comprehensive study addressing donor safety could help clarify risks of rare adverse events.

Pediatric cardiothoracic domino transplantation: the psychological costs and benefits

The first domino transplants were carried out in the UK in 1987, since which time 52 such procedures have been carried out involving patients within the paediatric cardiothoracic transplant programmes of Harefield and Great Ormond Street Hospitals. Although there are medical advantages in using domino organs--such as the ability for preoperative cross-matching, the heart not being subjected to the biochemical changes of brain death and less post-transplant coronary artery disease in the recipients of domino hearts compared with the recipients of hearts from cadaveric donors--the psychological sequelae for both donor and recipient have not been previously studied. The objective of this study was to identify the main psychological themes for patients involved in the domino programmes at the two hospitals, focusing on those situations where both patients were cared for in the same tertiary centre. Patients and their families were interviewed during routine outpatient clinic visits. Negative themes identified by patients included anxiety, guilt, resentment and anger if either patient had a poor outcome or suffered significant complications, disappointment and low self-esteem for potential donors whose heart was not used and recipient awareness of donor characteristics. Positive themes included gratefulness, comfort for the recipient that someone had not had to die for them directly and the benefit to the donor of giving their heart to another patient. In conclusion, domino transplantation has many medical advantages but there are significant negative psychological concomitants which need to be addressed within the multi-disciplinary management of these patients.

Preparing children to be bone marrow donors

PURPOSE/OBJECTIVES

To review literature regarding children as bone marrow donors and describe the evaluation of an individualized intervention to support children who will be donors for parents or siblings.

DATA SOURCE

Research studies, abstracts, and clinical reports describing interventions or psychosocial issues related to child donors, parent interviews, and clinical experiences.

DATA SYNTHESIS

Child marrow donors and caregivers benefit from interventions that illuminate the process and provide psychosocial support. Use of a teaching book enhances intervention and provides a tool for parents to use after transplantation.

CONCLUSIONS

Psychosocial distress in child marrow donors and parents can be minimized through education and therapeutic interventions. Research is needed to validate the efficacy of interventions and determine whether psychosocial complications are decreased.

IMPLICATIONS FOR NURSING

Child donors, especially those for parents, should receive support and attention for their unique psychosocial needs.
