Adoptive T Cell Immunotherapy for Patients with Primary Immunodeficiency Disorders.

ABSTRACT: Primary immunodeficiency disorders (PID) are a group of inborn errors of immunity with a broad range of clinical severity but often associated with recurrent and serious infections. While hematopoietic stem cell transplantation (HSCT) can be curative for some forms of PID, chronic and/or refractory viral infections remain a cause of morbidity and mortality both before and after HSCT. Although antiviral pharmacologic agents exist for many viral pathogens, these are associated with significant costs and toxicities and may not be effective for increasingly drug-resistant pathogens. Thus, the emergence of adoptive immunotherapy with virus-specific T lymphocytes (VSTs) is an attractive option for addressing the underlying impaired T cell immunity in many PID patients. VSTs have been utilized for PID patients following HSCT in many prior phase I trials, and may potentially be beneficial before HSCT in patients with chronic viral infections. We review the various methods of generating VSTs, clinical experience using VSTs for PID patients, and current limitations as well as potential ways to broaden the clinical applicability of adoptive immunotherapy for PID patients.

Project description:BackgroundCaregivers of children with primary immunodeficiency disorders (PIDs) experience significant psychological distress during their child's hematopoietic cell transplantation (HCT) process.ObjectivesThis study aims to understand caregiver challenges and identify areas for health care system-level improvements to enhance caregiver well-being.MethodsIn 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.ResultsAmong 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.ConclusionsCertain 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.
