DESCRIPTION (provided by applicant): Primary immune deficiencies (PIDs) are rare, life-threatening inherited defects in the immune system. The focus of the PID Treatment Consortium (PIDTC) will be on three PIDs that can be cured with hematopoietic cell transplantation (HCT), enzyme replacement or gene therapy: severe combined immunodeficiency (SCID), Wiskott-Aldrich syndrome (WAS) and chronic granulomatous disease (CGD). The objectives of the consortium are to characterize the long term outcomes and late effects in children with SCID, WAS and CGD who undergo HCT; to define the critical factors and biologic markers that influence the outcomes of children with SCID, WAS and CGD following HCT; to design and implement prospective clinical trials that improve care for children with PID; to prove the feasibility of newborn screening for SCID; and to provide training to physician scientists in the understanding and treatment of PIDs. Project 1 is a prospective study of SCID infants to identify early biomarkers and other disease- or HCT-related factors that affect engraftment, early immune reconstitution and survival. Project 2 is a cross-sectional retrospective study of SCID, exploring patient- and HCT-related factors that affect long term survival, immune reconstitution, late effects and quality of life. Project 3 addresses early and long-term outcomes following HCT in WAS and CGD, evaluating the degree of engraftment on outcome and identifying which patients with CGD are most likely to benefit from HCT. The Pilot Project Program will start with a Pilot Study of newborn screening for SCID. It will determine the efficacy of a novel test using newborn blood spots for early detection of SCID among Navajo Indians, who have a high incidence of SCID. The PIDTC encompasses 14 major centers that care for the majority of SCID, WAS and CGD patients in North America, bringing together for the first time physician/scientists with broad expertise in genetics, molecular biology, immunology, HCT, gene therapy and medical management. Parent advocacy groups will participate in PIDTC operations and oversight, subject recruitment, and dissemination of information resulting from our studies. These studies will resolve critical questions concerning HCT for these disorders and form the basis for future prospective clinical trials.

描述（由申请人提供）：原发性免疫缺陷（PID）是免疫系统中罕见的、危及生命的遗传性缺陷。 PID 治疗联盟 (PIDTC) 的重点将放在三种可通过造血细胞移植 (HCT)、酶替代或基因疗法治愈的 PID：严重联合免疫缺陷 (SCID)、Wiskott-Aldrich 综合征 (WAS) 和慢性肉芽肿性关节炎疾病（CGD）。该联盟的目标是描述接受 HCT 的 SCID、WAS 和 CGD 儿童的长期结果和后期影响；确定影响 SCID、WAS 和 CGD 儿童 HCT 后结局的关键因素和生物标志物；设计和实施前瞻性临床试验，以改善对 PID 儿童的护理；证明新生儿SCID筛查的可行性；并为医师科学家提供了解和治疗 PID 的培训。项目 1 是一项针对 SCID 婴儿的前瞻性研究，旨在确定影响植入、早期免疫重建和存活的早期生物标志物和其他疾病或 HCT 相关因素。项目 2 是 SCID 的横断面回顾性研究，探索影响长期生存、免疫重建、迟发效应和生活质量的患者和 HCT 相关因素。项目 3 讨论 WAS 和 CGD 中 HCT 后的早期和长期结果，评估结果的植入程度并确定哪些 CGD 患者最有可能从 HCT 中受益。该试点项目将从新生儿 SCID 筛查试点研究开始。它将确定一种使用新生儿血斑进行早期检测 SCID 的新型测试的功效，该测试可在 SCID 发病率较高的纳瓦霍印第安人中进行早期检测。 PIDTC 包含 14 个主要中心，为北美的大多数 SCID、WAS 和 CGD 患者提供护理，首次汇集了在遗传学、分子生物学、免疫学、HCT、基因治疗和医疗管理方面具有广泛专业知识的医生/科学家。家长倡导团体将参与 PIDTC 的运作和监督、受试者招募以及我们研究结果的信息传播。这些研究将解决有关这些疾病的 HCT 的关键问题，并为未来的前瞻性临床试验奠定基础。
