Filter by:This is a two part protocol (Parts A and B) in healthy volunteers evaluating the pharmacokinetics/ pharmacodynamics (PK/PD) of azithromycin to investigate the usefulness of various biomarkers (e.g., Interleukin-10 (IL-10), Granulocyte macrophage colony-stimulating factor (GM-CSF), mature dendritic cell (MDC), with and without ex vivo lipopolysaccharide (LPS) stimulation) as markers of macrolide anti-inflammatory activity. Part A is a randomized, open-label parallel group study evaluating PK/PD of a single azithromycin dose of 250 or 1000 mg. Data from Part A will be used to assess the dose resulting in induction/inhibition of various ex vivo biomarkers relative to a 250 mg dose of azithromycin (the clinical dose used in treatment of neutrophil-induced inflammatory conditions). This information will guide the range of doses to be studied in a first time in humans (FTIH) study of a new chemical entity. Part B is a repeat dose study treating subjects with Azithromycin (250 mg every other day for 3 weeks), the dose approximates that used in the treatment of chronic neutrophil related inflammatory conditions. This information will provide insight into whether the biomarker effects change over time on repeat dosing and any potential differences observed between single and repeat doses.
The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study is being conducted among VITAL participants and will examine whether vitamin D or fish oil have effects upon A) autoimmune disease incidence, B) biomarkers of systemic inflammation, and C) chronic knee pain. Blood samples at baseline and in follow-up will be collected in a randomly selected subcohort of 1500 individuals and analyzed for changes in biomarkers of systemic inflammation: C-reactive protein, interleukin-6, and tumor necrosis factor-receptor 2. Approximately 1300 individuals with chronic, frequent knee pain will be followed with annual questionnaires to evaluate the effects of the supplements on chronic knee pain.
This study is an access and distribution protocol for unlicensed cryopreserved cord blood units (CBUs) in pediatric and adult patients with hematologic malignancies and other indications.
This non-interventional, epidemiological study assesses long-term outcomes in subjects receiving immunoglobulins (IgG) for any treatment purpose, irrespective of the regimen prescribed by the treating physician, under routine clinical conditions in Germany. Long-term outcome data are collected on patient characteristics in the various indications, drug utilization of intravenous and subcutaneous IgG (e.g. treatment and dosing patterns), effectiveness (i.e. number of infections), tolerability, health related quality of life, and economic variables (number of hospitalizations, sick-leave days etc.) with the possibility to estimate direct costs.
Background: - Some children experience a sudden onset of symptoms similar to those found in obsessive-compulsive disorder that may be caused by the body s reaction to an infection with streptococcal bacteria, most commonly seen as strep throat or scarlet fever. When the body s immune system reacts against brain cells following a streptococcal infection, the condition is known as PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections). The immune system response can be inactivated by treatment with a drug known as intravenous immunoglobulin (IVIG). Because there is insufficient research on IVIG s effects on the immune system of children with PANDAS, including whether IVIG is helpful in treating obsessive-compulsive symptoms related to PANDAS, researchers are interested in examining whether IVIG is an appropriate treatment for PANDAS and its associated symptoms. Objectives: - To test the safety and effectiveness of intravenous immunoglobulin for the treatment of obsessive-compulsive disorder in children with PANDAS (pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection). Eligibility: - Children between 4 and 12 years of age who have obsessive-compulsive disorder (with or without a tic disorder) with sudden onset of symptoms following Group A streptococcal bacterial infections. Design: - Participants will be screened by telephone to obtain medical history and other information, followed by in-person screening at the National Institutes of Health Clinical Center. - Participants will be admitted to the hospital to receive 2 days of infusions of either IVIG or a placebo. Frequent blood samples, imaging studies, and other tests will be performed during this visit. - Six weeks after the inpatient stay, participants will return for further blood samples and other tests. Participants who did not receive the study drug, or who received the drug but did not respond to the initial IVIG infusion, will have the option to receive IVIG at this time. - Followup visits will take place 3 months and 6 months after the first evaluation, followed by yearly follow-ups for 5 additional years.
The purpose of this study is to collect DNA samples from patients undergoing routine care at the University of Chicago. These samples will be tested for differences in genes that may suggest greater risk of side effects or chance of increased benefit from certain medications. The results will be made available to the patient's treating physician and the researchers will track whether or not this information is used in routine health care.
This study will evaluate the use of the AMICUS device in patients where Therapeutic Plasma Exchange (TPE) is prescribed by their physicians.
The investigators have recently evidenced the presence of antibodies to endothelial cells and fibroblasts in patients with idiopathic or SSc-associated PAH. The investigators also have identified several target antigens of anti-fibroblasts antibodies. The objective of this study is to further investigate for the presence of antibodies to endothelial cells and fibroblasts in patients and characterize the antigen specificity of autoantibodies in patients with different types of non idiopathic and non SSc-associated PAH, such as PAH associated with HIV infection, porto-pulmonary hypertension, congenital heart diseases, systemic lupus erythematosus, mixed connective tissue disease and Sjögren's syndrome
The purpose of this SLE study is to evaluate the efficacy, safety and tolerability of two different doses of LY2127399 administered in addition to standard of care therapy in participants with active SLE.
Background: - The Center for Human Immunology, Autoimmunity, and Inflammatory Diseases (CHI) is conducting a variety of laboratory research experiments that require blood, bone marrow, urine, stool, and/or tissue samples from patients with a diagnosis of an immunologic, autoimmune, or inflammatory disorder, as well as from their healthy relatives. Donated samples will be sent to the CHI laboratory at the National Institutes of Health to be used in research that may provide more information on the changes in the immune system caused by these specific disorders. Objectives: - To collect blood, leukapheresis cells, bone marrow, urine, stool, cheek swab, and tissue samples from patients with immune-mediated and inflammatory diseases, as well as from family members, for ongoing exploratory research studies. Eligibility: - Individuals at least 2 years of age who have been diagnosed with an immune-mediated or inflammatory disease, or have signs or symptoms of an immune or inflammatory disease without a formal diagnosis. - Immediate family members (parent, child, sibling, grandchild) of the above mentioned individuals. Design: - Participants will be screened with a complete medical history, physical examination, and blood and urine samples. - Participants will provide blood, urine, stool, cheek swab, and tissue samples as required by the study researchers. - Participants who have immune or inflammatory diseases will also provide blood and bone marrow samples collected through biopsies and leukapheresis (to collect specific blood cells). - Adult relatives will provide additional samples through more invasive procedures such as leukapheresis and bone marrow biopsies. Child relatives (between 2 and 18 years of age) will not undergo these invasive procedures. - No treatment will be provided as part of this protocol.
