Filter by:The aim of the SAID study is to create a national resource in Sweden to enable comprehensive immunological analyses of an extremely complex and clinically challenging group of individuals with variable forms of immune system dysregulation. We hope to establish a biobank of primarily blood and fecal samples from children and adults, with confirmed or suspected immune dysregulation, as well as age- and sex- matched healthy controls, for comparisons of immune cell/mediator alongside various clinical presentations of these immunological diseases as well as microbiome samples as possible a possible modifier of clinical presentations. The project will also include the establishment of a national database with deep immunological data, treatment and clinical outcomes for these patients, accessible to participating researchers and clinicians.
Background: People with GATA2 deficiency have a mutation on the GATA2 gene. This gene affects immune function. People with this disease are prone to serious infections; in time, they may develop blood cancers. A hematopoietic stem cell (HSC) transplant can cure GATA2 deficiency, but using stem cells donated by other people can cause serious side effects. Objective: To test a new drug (JSP191) to see if it can make HSC transplants safer. Eligibility: People aged 6 to 70 years who have GATA2 deficiency. Design: Participants will be screened. They will have a physical exam, with blood and urine tests. They will have tests of their heart and lung function. They may have a bone marrow biopsy: Their hip will be numbed; a large needle will be inserted to draw out tissue from inside the pelvis. Participants will have a central venous catheter placed in a vein of the neck or chest. This will be used to draw blood and administer drugs. JSP191 will be given through the catheter about 11 days before the transplant. This is part of conditioning: preparing the body to receive the new stem cells. Conditioning also includes other medications and total body irradiation. Donor stem cells will be administered through the catheter. Participants will receive other approved drugs to help prevent side effects. Participants will stay in the hospital from the beginning of the conditioning until several weeks after the transplant. They will remain in the local area for 100 days after discharge; they will come to the clinic at least once a week during this time. Follow-up visits will continue for 3 years.
The aim of this study is to identify both the humoral immunological response through the detection of induced antibodies and the cellular immunological response through the detection of interferon gamma production by functional CD4+ and CD8+ cells in different groups of immunocompromised patients. For antibody detection, LIAISON® SARS-CoV-2 TrimericS assay (DiaSorin) will be used and for the evaluation of cellular immunity - QuantiFERON SARS-CoV-2 assay (QIAGEN).
The investigators will examine whether a combination of at-home nucleic acid amplification tests, on-demand telemedicine, and delivery of prescriptions such as Paxlovid quickly after testing positive for COVID-19, can reduce severe outcomes and hospitalization of immunocompromised patients and those who are 65 years and older. They will also analyze whether these efforts lower the cost of care compared to standard of care.
The overall purpose of the trial is to evaluate the efficacy and safety of possible combination antiviral therapy DAA (remdesivir + nirmatrelvir/r)∞ versus the reference monotherapy (nirmatrelvir/r alone) and to assess the efficacy and safety of increasing the nirmatrelvir/r course from 5- to 10 days in immunocompromised patients diagnosed with asymptomatic or mild to moderate COVID-19.
RESPIRE is a randomized, unblinded, controlled study to measure the impact of a strategy based on a PCR test on the adjustment of antimicrobial therapy in immunocompromised patients suspected with ventilator-associated or hospital-acquired pneumonia (VAP/HAP) requiring mechanical ventilation (MV) in Intensive Care Unit (ICU). The gold-standard microbiological diagnostic method for pneumonia in the ICU is based on culture identification and antimicrobial susceptibility testing. Results are obtained in several days after the initiation of empiric antimicrobial therapy, exposing patients to a potential inappropriate broad-spectrum antimicrobial treatment. We aim to measure the impact of a PCR-based strategy to improve the percentage of patients with VAP or HAP receiving targeted antimicrobial therapy 24 hours after diagnosis compared to standard care
Background: Allogeneic hematopoietic stem cell transplant involves taking blood stem cells from a donor and giving them to a recipient. The transplants are used to treat certain diseases and cancers. Researchers want to see if the transplant can treat VEXAS Syndrome. Objective: To see if stem cell transplants can be successfully performed in people with VEXAS and even improve the disease. Eligibility: People ages 18-75 who have VEXAS Syndrome that has caused significant health problems and standard treatment either has not worked or is not available. Design: Participants will be screened with: Physical exam Medical review Blood and urine tests Heart and lung function tests Bone marrow biopsy Participants will have a chest x-ray. They will have an imaging scan of the head, chest, abdomen, pelvis, and sinus. They will have a bone density scan. They will have a dental exam and eye exam. They will meet with specialists. They will repeat some screening tests. Participants will be admitted to the NIH hospital. They have a central venous catheter put into a vein in the chest or neck. They will receive drugs to prepare their bone marrow for the transplant. They may have total body irradiation. They will receive the donor stem cells through the catheter. They will get other drugs to prevent complications and infections. After discharge, they must stay in the DC area for 3 months for weekly study visits. Participants will have study visits 30, 60, 100, 180, 210, 240, 300, and 360 days later. After that, they will have yearly visits for 2 years and then be contacted yearly by phone....
The first version of this preprint article is registered on the 4th of May 2020 under the digital object identifier of:10.31219/osf.io/u56fc. COVID-19 infections virus spread worldwide and impact many countries with sever economical sequences. The effective antiviral medication or vaccination for the virus is unavailable until the present date and it takes months or years to discover the effective treatment or test the efficacy of the discovered treatment. Based on these facts, the human immune system against the virus may have an effective role to regulate the infection and reduce the mortality rate among the infected patients. This proposed research article aims to explore the available medication/ natural supplementation to boost the immunity system of the patients against COVID-19 infections and reduce the mortality rate among infected patients. Methods: a proposed clinical trial will be carried out to investigate the effect of the different treatment modalities on the human immune system against COVID-19 infection.
The purpose of this study is to identify if there is a relationship between multiple sclerosis disease-modifying therapy exposure, immunodeficiencies, and infection risk in subjects living with MS.
Background: The immune system defends the body against disease. It has many different parts spread out in the body, including in the blood and skin. To learn more about it, researchers want to study samples from people with healthy immune systems and people with conditions that affect how the immune system works. Objective: To learn about how the different parts of the immune system come together to make a whole. Eligibility: People age 2 and older who have a condition that affects the immune system or have a family member with such a condition. Design: Participants will be screened with medical and medicine review. Other lab tests may also be reviewed. Some participants will take a pregnancy test. Participants will give blood samples. They may also give saliva, stool, and urine samples. A sterile cotton swab may be rubbed over their skin or inside the cheek or nose to collect cells. If participants have samples collected as part of their regular medical care, their doctor may be asked to send parts of the samples that otherwise would be thrown away. These samples may be from biopsies, endoscopies, or other procedures. Some participants may have optional skin punch biopsies. For this, their skin is numbed. Then a tool removes 1 or 2 small pieces of skin from the forearm or thigh. Participants medical records will be checked to see if they have any changes in their health over time. If they have a study visit, they may talk about their medical history and have a physical exam. Participation lasts 5 years....
