Filter by:Chronic granulomatous disease (CGD) is a rare genetic disease of innate immune due to the malfunction of phagocytic cells unable to destroy pathogens during infection. The four genes implicated are CYBB, CYBA, NCFA and NCF2 respectively encoding Nox2, p22phox, p47phox and p67phox. Nox2 analogs have recently been discovered in cells other than phagocytes. So the question arises on physiopathological impact of the absence of theses proteins not only in phagocytes but also in other cells types such as fibroblasts or neurons. The principal objective is thus to study the impact of protein deficits Nox2 and p22phox, in the pathophysiology of neurons from inducible pluripotent bone marrow cells (iPSC). For this purpose, a collection was built of fibroblasts and keratinocytes from patients with different forms of CGD to get iPSC similar to embryonic marrow cells and differentiable into several cell types (neurons, phagocytes).
The investigators hypothesize that neutrophils and monocytes developed under the influence of Interferon- gamma-1b (IFN-γ-1b, Actimmune*) in vivo will display enhanced function across a broad range of activities related in large part to the transcriptional activation effects of this cytokine. The investigators will evaluate the effects of IFN-γ in healthy human subjects in vivo on gene expression, biologic activity markers, and functional activity of myeloid cells in single dose studies and in steady state studies.
Many genetic diseases of lymphohematopoietic cells (such as sickle cell anemia, thalassemia, Diamond-Blackfan anemia, Combined Immune Deficiency (CID), Wiskott-Aldrich syndrome, chronic granulomatous disease, X-linked lymphoproliferative disease, and metabolic diseases affecting hematopoiesis) are sublethal diseases caused by mutations that adversely affect the development or function of different types of blood cells. Although pathophysiologically diverse, these genetic diseases share a similar clinical course of significant progressive morbidity, overall poor quality of life, and ultimate death from complications of the disease or its palliative treatment. Supportive care for these diseases includes chronic transfusion, iron chelation, and surgery (splenectomy or cholecystectomy) for the hemoglobinopathies; prophylactic antibiotics, intravenous immunoglobulin, and immunomodulator therapies for the immune deficiencies; and enzyme replacement injections and dietary restriction for some of the metabolic diseases. The suboptimal results of such supportive care measures have led to efforts to implement more aggressive therapeutic interventions to cure these lymphohematopoietic diseases. The most logical strategies for cure of these diseases have been either replacement of the patient's own hematopoietic stem cells (HSC) with those derived from a normal donor allogeneic bone marrow transplant (BMT) or hematopoietic stem cell transplant (HSCT), or to genetically modify the patient's own stem cells to replace the defective gene (gene therapy).
Background: - Chronic Granulomatous Disease (CGD) causes immune system problems. Treatment is usually a bone marrow transplant from a fully matched donor. Researchers want to try using partially matched donors for patients who do not have a fully matched donor available. The researchers will also use the drug cyclophosphamide to try to improve the outcomes when using a partially matched donor. Objective: - To learn the effectiveness of using cyclophosphamide with a transplant from a partially matched donor in treating CGD. Eligibility: - Recipients: age 2-65 with CGD with an ongoing infection that has not been cured by standard treatment and no fully matched donor available in an appropriate timeframe. Design: - Recipients will: - be admitted to the hospital 2 weeks before transplant. - be screened with blood and urine tests, breathing and heart health tests, X-rays, and/or magnetic resonance imaging. They may have a bone marrow aspiration and biopsy. - meet with a social worker and dentist. - get chemotherapy, radiation, and other medicines. - get an intravenous (IV) catheter in their chest. - have the transplant. - get more medicines and standard supportive care. - have blood drawn frequently. - have to stay in the Washington, D.C. area for 3 months post-transplant. - be followed closely for the first 6 months, and then less frequently for at least 5 years.
This study is a longitudinal and cross-sectional evaluation of patients with Chronic Granulomatous Disease (CGD) who received or are receiving hematopoietic cell transplantation (HCT) for their disease under a variety of protocols used by participating institutions compared to a control non-HCT group receiving standard care. Investigators at multiple centers caring for patients with CGD in North America and 3 centers in Europe will participate. Patients with CGD will have been treated according to institutional practice and protocols. Investigators will enroll these patients as subjects in this protocol. This study will investigate which patients benefit most from HCT, and what types of transplants are optimal for patients with CGD, in the context of overall outcomes in CGD patients with and without transplant.
Background: - There are very few documents to help young adults living with advanced cancer discuss their concerns and end-of-life preferences. A new document, Voicing My CHOiCES, allows young adults to explain what kind of care they would want if they became unable to communicate or make medical decisions on their own. Researchers want to study if this document is helpful. Objective: - To study if Voicing My CHOiCES can reduce anxiety, improve sense of support, and improve communication about advanced care planning. Eligibility: - Adults 18 to 39 years old being treated for cancer. Design: - Participants will answer questions about their age, gender, employment, religion, health, and marital status. They will also complete several brief questionnaires: 1. General Anxiety Short Form 2. Peace, Equanimity and Acceptance in the Cancer Experience 3. Functional Assessment of Social Support 4. Quality of Communication 5. Prior Communication about Advanced Care Planning - Then a health care professional will introduce Voicing My CHOiCES . Participants will review the document and comment on parts they find relevant. They will also say if any important items are missing. Participants will complete 3 pages of the document with the assistance of a health care provider. They will be asked for positive and negative observations. - The second stage of the study will take place about 1 month later. Participants will repeat the brief questionnaires listed above. They will be asked if they shared any of the preferences they described when completing the 3 pages of Voicing My CHOiCES during visit 1 with a family member, friend, or health care provider. Research staff will ask the participant for permission to contact the people they spoke with in order to learn whether their conversations about the document were helpful. They will ask for feedback on how to make Voicing My CHOiCES more helpful.
HLH, HLH-related disorders, Chronic Granulomatous (CGD), HIGM1, Immune dysregulation, polyendocrinopathy, enteropathy, and X-linked inheritance (IPEX) and severe LAD-I represent primary immune disorders that are typically fatal without Hematopoietic Cell Transplant (HCT). However, transplant is often complicated by inflammation, infection and other co-morbidities. In addition, these disorders have been shown to be cured with partial chimerism, making them an ideal target for the use of reduced intensity approaches, where a portion of patients may not achieve full donor chimerism, but instead achieve stable mixed chimerism. Reduced-intensity conditioning strategies have demonstrated improved survival with decreased Treatment Related Mortality (TRM) in institutional series for patients with HLH (Cooper et al., 2006; Marsh et al., 2010; Marsh et al., 2011). However, graft loss and unstable chimerism remain challenges. An institutional case series from Cincinnati Children's Hospital demonstrated full or high-level chimerism and improved durable engraftment using intermediate (Day -14) timing alemtuzumab (Marsh et al., 2013b). This study aims to test the efficacy of the Intermediate RIC strategy in a prospective multi-center study including HLH as well as other primary immunodeficiencies where allogeneic transplant with RIC has been shown to be feasible and stable chimerism is curative.
This is a single arm, phase I study to assess the tolerability of abatacept when combined with cyclosporine and mycophenolate mofetil as graft versus host disease prophylaxis in children undergoing unrelated hematopoietic stem cell transplant for serious non-malignant diseases as well as to assess the immunological effects of abatacept. Participants will be followed for 2 years.
This study hypothesizes that a reduced intensity immunosuppressive preparative regimen will establish engraftment of donor hematopoietic cells with acceptable early and delayed toxicity in patients with immune function disorders. A regimen that maximizes host immune suppression is expected to reduce graft rejection and optimize donor cell engraftment.
This is a standard of care treatment guideline for allogeneic hematopoetic stem cell transplant (HSCT) in patients with primary immune deficiencies.
