Hematopoietic cell transplantation (HCT) is an elective, curative treatment option for patients with sickle cell disease (SCD). Transplant requires extensive self-management behaviors to be successful. The purpose of this study was to describe potential barriers and facilitators to self-management in a group of pediatric patients with SCD prior to HCT and their medical outcomes post-HCT. A multiple case study approach was used to describe 4 pairs of transplant recipients grouped by age, donor type, and donor source. Each pair included a case with minimal and increased post-HCT complications. Complications included readmissions, graft-versus-host disease, systemic infections, and survival in the first year post-HCT. Variables were retrospectively collected and content analyzed to identify barriers and facilitators within and across pairs using existing self-management frameworks. While higher risk transplants experienced more complications, 3 of the 4 cases with increased complications had a larger number of modifiable barriers identified compared with those experiencing minimal complications. At least one modifiable barrier and multiple facilitators were identified in all cases. A standardized psychosocial assessment process with an established plan to mitigate barriers and promote facilitators to self-management is essential to optimize outcomes in patients with SCD undergoing elective HCT.

Abstract Hematopoietic Cell Transplantation (HCT) from sibling donors has been demonstrated to cure sickle cell disease. Concerns about high regimen related toxicity particularly in older patients and in those with advanced organ damage and the potential for late sequelae such as chronic graft-versus-host disease (GVHD) and infertility have limited the applicability of HCT. HCT following a reduced intensity conditioning (RIC) regimen has the potential for reducing toxicity and making this curative therapy more acceptable and applicable to this group of patients. We report preliminary results on the first five patients enrolled on a pilot study to evaluate the safety and efficacy of HCT following a RIC regimen for patients with high risk sickle cell disease. All patients received bone marrow from a matched sibling donor. The conditioning regimen consisted of Busulfan 2 mg/kg orally q12 hr x 2 days (0.8mg/kg IV q 6 hr x 2 days for patient#3, 4, 5), Fludarabine 35 mg/m2/dose IV daily x 5 days, anti-thymocyte globulin 30 mg/kg/dose IV daily x 5 days and total lymphoid irradiation 500 cGy with shielding of the liver, lungs, heart, and gonads. GVHD prophylaxis consisted of cyclosporine A and Mycophenolate mofetil. Clinical characteristics, outcomes and donor chimerism in peripheral blood genomic DNA and of subjects are summarized in the Table.1 The preparative regimen was well tolerated with no serious infections or mucositis in any patient. No patient has had recurrence of previous sickle cell related symptoms. Lineage-specific chimerism analysis (patients # 3, 4, 5), reveal predominance of donor erythropoiesis (Table 2). These findings indicate that HCT for sickle cell disease following a RIC regimen is well tolerated and can lead to stable long term engraftment.

Abstract Excellent outcomes in hematopoietic cell transplantation (HCT) from HLA-identical siblings, improvements in conditioning regimens, novel graft-versus-host disease prophylaxis, and the availability of alternative donors have all contributed to the increased applicability and acceptability of HCT for sickle cell disease (SCD). In young children with symptomatic SCD with an available HLA-identical related donor, HCT should be carefully considered. HCT from alternative donors is typically undertaken only in patients with severe symptoms, causing or likely to cause organ damage, and in the context of clinical trials. Patients undergoing HCT for SCD require careful counseling and preparation. They require careful monitoring of unique organ toxicities and complications during HCT. Patients must be prospectively followed for a prolonged time to determine the long-term outcomes and late effects of HCT for SCD. Thus, there is a need for a universal, longitudinal clinical registry to follow patients after HCT for SCD in conjunction with individuals who do not receive HCT to compare outcomes. Antibody-based conditioning and ex-vivo umbilical cord blood expansion are likely to improve the availability and acceptability of HCT. In addition, new disease-modifying drugs and the emerging option of the autologous transplantation of gene-modified hematopoietic progenitor cells are likely to expand the available therapeutic options and make decision-making by patients, physicians, and caregivers even more complicated. Future efforts must also focus on determining the impact of socioeconomic status on access to and outcomes of HCT and the long-term impact of HCT on patients, families, and society.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Hematopoietic cell transplantation (HCT) is a treatment option utilized to cure many childhood disorders, with cancer, sickle cell disease (SCD), and aplastic anemia being a few. The decision of whether or not to pursue HCT involves uncertainty and risk. Pediatric patients with SCD and their families undergo a decision-making process distinct from patients with childhood cancer. Patients with sickle cell disease (SCD) realize an awareness of unpredictable disease progression and conflict when considering HCT, while patients with cancer perceive an urgency for survival. We applied Connor's Framework of Decisional Conflict and a multiple-case study approach to describe the level and source of decisional conflict in patients with SCD and their families in a real-life decision choice of HCT. The contribution of the pediatric patient in the decision was also described in our four families. Observation, survey, and interview methods allowed us to gain an in-depth understanding of their conflict. Through pattern-matching and cross-case synthesis, we found that the level and sources of conflict among 11 participants varied within and across family members. Some experienced levels that resulted in a delayed decision or feeling unsure. The patients and their family members ultimately navigated their uncertainties together to come to consensus on whether to proceed with HCT. Future studies should implement individualized interventions from a family research perspective to decrease the decisional conflict this population faces.

Hematopoietic stem cell transplantation can be curative for sickle cell disease, but decision-making is often complex. This How I Treat provides a perspective on how to negotiate this process for an individual patient.
