Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers Clinical Trials Information presented on Clinical Trials Search isn't designed to be a substitute for certified healthcare advice, travels to or professional assistance using a genuine medical doctor. We are not physicians. Always confer with your dr. about Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers Clinical research trials and Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers medical trials happen in hundreds of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectualness of new drugs. The intention of the studies / undertakings is to solve certain human healthcare questions. Clinical trials are a popular manner for mDs, government agencies, and private sector companies to locate treatments for all forms of circumstances, such as Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers. Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment choices before they are available to the general public. Some times the human subjects get treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers clinical trial. Participants frequently get the best healthcare available for their Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers condition. Risks are a reality, nonetheless, and can include extra or frequent physician trips, medical risks (possibly life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with exacting guidelines to protect clinical trials subjects.

Blood Component Collection from Patients with Rheumatic Disease and Healthy Volunteers
For Condition: Rheumatic Diseases,Healthy
Status: Recruiting
Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) ,
Synopsis: This study will collect white blood cells or plasma (the liquid part of the blood), or both, from healthy volunteers and from patients with rheumatic disorders for research purposes. Rheumatic disorders involve abnormalities of the immune system, the body's defense against disease. The immune system consists of white blood cells such as lymphocytes and monocytes, which produce substances such as antibodies and cytokines. White cells and plasma will be collected through a procedure called apheresis (described below). Healthy volunteers and patients with confirmed or suspected rheumatic disease who are 18 years of age or older may be eligible for this study. Patients must be participating in a current protocol of the National Institute of Arthritis and Musculoskeletal and Skin Diseases. All candidates will be screened with a history, physical examination, and blood tests for hepatitis B and C and HIV infection. Women of childbearing age will be tested for pregnancy. Routine blood tests will be done in all volunteers, and in patients where needed. Pregnant women and people who test positive for hepatitis or HIV may not participate. Participants will undergo apheresis to collect lymphocytes, monocytes, or plasma from the blood. For this procedure, a needle is placed in a vein in the arm. Blood flows from the vein through a tube (catheter) into a machine that spins the blood, separating it into its components. The required cells or plasma are extracted, and the rest of the blood, including the red cells and platelets, is returned to the body through the same needle or through a second needle placed in the other arm. Cells collected from volunteers will be used in studies comparing the number and function of similar cells from patients with rheumatic diseases, focusing on the differences in number and function of the cells in health and disease. Components collected from patients will be used only for studies described in the protocol in which they are currently enrolled.
Details: Blood components will be collected using apheresis from normal volunteers and patients with rheumatic diseases. Mononuclear cells and plasma will be used by various investigators for research studies.

Protocol Entry Criteria: INCLUSION CRITERIA - Subjects with Rheumatic Diseases: Patients with a diagnosed or suspected rheumatic disease, who are actively involved in a NIAMS protocol (have a current, signed consent form) Ability to give informed consent Age greater than or equal to 18 years EXCLUSION CRITERIA - Subjects with Rheumatic Diseases: History of allergy to acid-citrate-dextrose (ACD) anticoagulant History of bleeding diatheses Hemoglobin less than 9.0 g/dL Platelet count less than 50,000/mm(3) Pregnancy Inadequate peripheral venous access Active hepatitis B, C and/or HIV infection Symptomatic coronary artery or valvular heart disease Any concomitant illness that in the opinion of the investigators will substantially increase risk of apheresis. INCLUSION CRITERIA - Healthy Volunteers: Subjects shall meet all donor eligibility criteria for autologous blood donation recommended or required by the Standards of the American Association of Blood Banks (1) and the Code of Federal Regulations of the Food and Drug Administration (2), with the exception of the travel exclusions related to malaria exposure and hypothetical exposure to the agent of variant Creutzfeldt-Jacob disease. Ability to give informed consent Age greater than or equal to 18 years EXCLUSION CRITERIA - Healthy Volunteers: History of autoimmune or chronic rheumatic disease within the last 5 years, with the exception of osteoarthritis Active hepatitis B, C, and/or HIV infection History of allergy to acid-citrate (ACD) anticoagulant History of coagulopathies and bleeding diatheses Symptomatic coronary artery disease or valvular heart disease Hemoglobin less than 12.0 g/dL Platelet count less than 100,000/cubic mm Pregnancy Inadequate peripheral venous access Any concomitant illness that in the opinion of the investigators will substantially increase the risk of apheresis or make the volunteer ineligible for study controls are needed for (eg: active infection, allergies, etc.)
