Quality of Life of Patients with Wiskott Aldrich Syndrome and X-Linked Thrombocytopenia: a Study of the Primary Immune Deficiency Consortium (PIDTC), Immune Deficiency Foundation, and the Wiskott-Aldrich Foundation.

BACKGROUND: We undertook a study to determine the impact of Wiskott Aldrich Syndrome (WAS) and X-linked thrombocytopenia (XLT) and their therapies upon the health-related quality of life (HRQOL) of patients and their families. MATERIALS AND METHODS: We undertook a survey of patients and their families, who self-identified as having either WAS or XLT. We assessed the PedsQL™ 4.0, the parent proxy form, and the family impact module. These results were compared with normative data from previously published reports. RESULTS: Sixty-eight patients (29 patients completed both the PedsQL™ 4.0 and the parent proxy form; 21 completed only the PedsQL™ 4.0; and 18 completed only the parent proxy form) were included. In contrast to patient-reported outcomes, parents of patients who had a bone marrow transplant (BMT) reported that their children had better QOL scores compared with those who did not (82.6 vs. 73.3, p = 0.023). The QOL of patients vs. previously published normative data showed decreases in patient scores for psychosocial health (72.62 vs. 86.58, p = < 0.001), emotional functioning (69.91 vs. 82.64, p = < 0.001), social functioning (77.55 vs. 91.56, p = < 0.001), and school functioning (70.46 vs. 85.67, p = < 0.001). The family impact study revealed deficits in emotional, social, and cognitive functioning, communication, and worry. CONCLUSION: These results show that patients with WAS/XLT are significantly impacted with respect to QOL. BMT offered a better QOL for patients according to parents, but not as reported by the patients. Future studies should incorporate QOL to provide more data and a better understanding of outcomes for long-term survivors and decision-making regarding BMT.

Supporting caregivers during hematopoietic cell transplantation for children with primary immunodeficiency disorders.

BACKGROUND: Caregivers of children with primary immunodeficiency disorders (PIDs) experience significant psychological distress during their child's hematopoietic cell transplantation (HCT) process. OBJECTIVES: This study aims to understand caregiver challenges and identify areas for health care system-level improvements to enhance caregiver well-being. METHODS: In this mixed-methods study caregivers of children with PIDs were contacted in August to November 2017 through online and electronic mailing lists of rare disease consortiums and foundations. Caregivers were invited to participate in an online survey assessing sociodemographic variables, the child's medical characteristics, psychosocial support use, and the World Health Organization-5 Well-Being Index. Open-ended questions about health care system improvements were included. Descriptive statistics and linear multivariate regression analyses were conducted. A modified content analysis method was used to code responses and identify emergent themes. RESULTS: Among the 80 caregiver respondents, caregivers had a median age of 34 years (range, 23-62 years) and were predominantly female, white, and married with male children given a diagnosis of severe combined immune deficiency. In the adjusted regression model lower caregiver well-being was significantly associated with lower household income and medical complications. Challenges during HCT include maintaining relationships with partners and the child's healthy sibling or siblings, managing self-care, and coping with feelings of uncertainty. Caregivers suggested several organizational-level solutions to enhance psychosocial support, including respite services, online connections to other PID caregivers, and bedside mental health services. CONCLUSIONS: Certain high-risk subpopulations of caregivers might need more targeted psychosocial support to reduce the long-term effect of the HCT experience on their well-being. Caregivers suggested several organizational-level solutions for provision of this support.

Psychosocial services for primary immunodeficiency disorder families during hematopoietic cell transplantation: A descriptive study.

OBJECTIVE: Caregivers for patients undergoing hematopoietic cell transplantation (HCT) are susceptible to significant psychosocial distress. This cross-sectional study aimed to describe psychosocial support services offered and used by caregivers of pediatric primary immune deficiency (PID) during HCT at 35 hospitals across North America. METHOD: Caregivers of pediatric patients with PID were recruited by e-mail to participate in an anonymous 140-question survey instrument between April and May 2016 (N = 171). RESULT: Of those meeting inclusion criteria (53%), family counseling services were only offered to fewer than half of caregivers (42%). Of the survey participants not offered counseling services, the majority desired family counseling (70%) and sibling counseling (73%). That said, when offered counseling, utilization rates were low, with 22% of caregivers using family counseling and none using sibling counseling. SIGNIFICANCE OF RESULTS: These results indicate the need to offer and tailor counseling services for families throughout the HCT process. Further research should focus on reducing barriers to utilization of counseling services such as offering bedside counseling services, online modalities, and/or financial assistance.

Primary Immune Deficiency Treatment Consortium (PIDTC) report.

The Primary Immune Deficiency Treatment Consortium (PIDTC) is a network of 33 centers in North America that study the treatment of rare and severe primary immunodeficiency diseases. Current protocols address the natural history of patients treated for severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome, and chronic granulomatous disease through retrospective, prospective, and cross-sectional studies. The PIDTC additionally seeks to encourage training of junior investigators, establish partnerships with European and other International colleagues, work with patient advocacy groups to promote community awareness, and conduct pilot demonstration projects. Future goals include the conduct of prospective treatment studies to determine optimal therapies for primary immunodeficiency diseases. To date, the PIDTC has funded 2 pilot projects: newborn screening for SCID in Navajo Native Americans and B-cell reconstitution in patients with SCID after hematopoietic stem cell transplantation. Ten junior investigators have received grant awards. The PIDTC Annual Scientific Workshop has brought together consortium members, outside speakers, patient advocacy groups, and young investigators and trainees to report progress of the protocols and discuss common interests and goals, including new scientific developments and future directions of clinical research. Here we report the progress of the PIDTC to date, highlights of the first 2 PIDTC workshops, and consideration of future consortium objectives.
