Filter by:Recent studies suggest that the JAK/STAT signaling pathway constitutes a new step in the clinical and therapeutic progress of sarcoidosis. Further investigations are necessary to identify the most suitable patients to receive treatment targeting this pathway, in particular in cases of severe sarcoidosis refractory to the various therapeutic lines.
Today, there is an increased use of non-medical, invasive cosmetic treatments globally without sufficient awareness of possible health risks. A particular problem is young men injecting large amounts of paraffin oil into skeletal muscles especially on upper arms and chest to increase the visible size of the muscles. Several case reports have suggested that intramuscular injection of paraffin oil induces foreign body reaction and granuloma formation and subsequently hypercalcemia. Our hypothesis is that increased generation of activated vitamin D (1,25(OH)2D3) in the marcrophages may be responsible for the persistent hypercalcemia. Now trhe investigators want to include a large group of men who injected 100-10.000 ml paraffin oil to identify risk factors for developing hypercalcemia and try to understand the pathogenesis of the disease. Additionally, granuloma tissue from selected patients will be cultured ex vivo to investigate whether they produce 1,25(OH)2D3 or PTHrP and to test which drugs can most effectively be used to lower calcium levels in these men. Subsequently, we will try to stratify the men according to the severity of the changes in calcium homeostasis as we suggest that this stratification will be the basis for future intervention trials
When children with chronic granulomatous disease (CGD) got BCG infection the treatment would be a tough task. The goal of the proposed research is to observe weather vitamin D supplementation can help the CGD children get through this challenge.
Background: CGD causes infections and inflammation. The only cure currently is a bone marrow transplant. Most often a perfectly matched bone marrow donor is used. Researchers want to see if they can lower the risks of using a mismatched donor. Objectives: To see if it is safe to use a related bone marrow donor who is only a partial match to a person with CGD. To see how well drugs given to a person before and after transplant help the body accept the transplant. Eligibility: People ages 4-65 with CGD for whom stem cell transplant may be a cure and who do not have a perfectly matched donor, related or unrelated. Design: Participants will be screened with: Medical history Physical exam Blood tests Participants will be admitted to the hospital about 2 weeks before the transplant. They will have blood, urine, breathing, and heart tests. They may have CT and/or MRI scans. They will have a needle inserted into their hipbone to remove marrow. They will have dental, neurologic, and psychologic tests. They will have a central catheter placed: A line will be placed into a vein in their upper chest. They will get drugs, chemotherapy, and radiation to prepare for the transplant. Participants will receive the donated cells through their catheter. The cells will be from one of their relatives. Participants will stay in the hospital about 6 weeks after the transplant. After they leave the hospital, participants will have to stay in the area with visits about 2 times a week for approximately 100 days post transplant. Then visits will be every 3 to 6 months for 2 years. Then visits will be once a year.
This is a Phase I/II clinical trial of gene therapy for treating Chronic Granulomatous Disease using a high-safety, high-efficiency, self-inactivating lentiviral vector TYF to functionally correct the defective gene. The objectives are to evaluate the safety and efficacy of the TYF-CGD gene transfer clinical protocol.
An open-label, multi-center, phase 2 study of the efficacy of denosumab in subjects with giant cell rich tumors of bone. The population will consist of subjects with the following tumor types: aneurysmal bone cysts (ABC), giant cell granuloma (GCG) and other giant cell rich lesions (primary bone, non-malignant).
Treatment Study to assess of safety and efficiency of conditioning with Plerixafor and G-CSF as additional agents for prevention of graft failure after transplantation in patients with chronic granulomatous disease
Chronic Granulomatous Disease (CGD) is an inherited immunodeficiency disorder which results from defects that prevent white blood cells from effectively killing bacteria, fungi and other microorganisms. Chronic granulomatous inflammation may compromise vital organs and account for additional morbidity. CGD is thought to affect approximately 1 in 200,000 persons, although the real incidence might be higher due to under-diagnosis of milder phenotypes. The first gene therapy approaches in X-CGD have shown that effective gene therapy requires bone-marrow (BM) conditioning with chemotherapy to make space for the gene-modified cells to engraft. These studies demonstrated that transplantation of gene modified stem cells led to production of white blood cells that could clear existing infections. However, some trials using mouse-derived retroviral vectors were complicated by the development of myelodysplasia and leukemia-like growth of blood cells. This trial will evaluate a new lentiviral vector that may be able to correct the defect, but have much lower risk for the complication. This study is a two-part, prospective non-controlled, non-randomized Phase I/II clinical trial to assess the safety, feasibility and efficacy of cellular gene therapy in patients with chronic granulomatous disease using transplantation of autologous bone marrow CD34+ cells transduced ex vivo by the G1XCGD lentiviral vector containing the human CGD gene. Primary objectives include evaluation of safety and evaluation of efficacy by biochemical and functional reconstitution in progeny of engrafted cells and stability at 12 months. Secondary objectives include evaluation of clinical efficacy, longitudinal evaluation of clinical effect in terms of augmented immunity against bacterial and fungal infection, transduction of CD34+ hematopoietic cells from X-CGD patients by ex vivo lentivirus-mediated gene transfer, and evaluation of engraftment kinetics and stability. Approximately 3-6 patients will be treated per site with a goal of 16 total patients to be treated with G1XCGD lentiviral vector.
X-linked chronic granulomatous disease (X-CGD) is a rare inherited immune defect, which is caused by the inability of phagocytic cells to produce reactive oxygen species due to a defect in the gp91phox subunit of the NADPH oxidase complex. X-CGD patients suffer from recurrent and life-threatening infections and severe hyperinflammatory complications. The only curative treatment for X-CGD is allogenic hematopoietic stem cell transplantation, but this procedure implies severe risks and many patients lack an appropriate donor. Therefore alternative curative approaches are urgently needed. In this study, patients will be treated with gene-corrected autologous CD34+ cells, using a SIN gammaretroviral vector for ex-vivo gene-therapy.
The purpose of this study is to determinate whether in newborns just cleaning the umbilical stump when changing diapers (with water and soap if necessary)is effective in preventing local cord infections and not delaying cord separation as just as cord care alcohol, usually applied in our hospital and suggested to parents at dismission.
