Studies of the Natural History of Rheumatic Diseases
What this study is about
This study will explore the causes of rheumatic diseases and why many of them affect certain minority communities more severely. Rheumatic diseases may cause joint pain, stiffness or swelling. Some can involve bones, muscles, tendons or ligaments. Some cause abnormalities of the immune system-the body s defense against disease.
View original scientific description
This study will explore the causes of rheumatic diseases and why many of them affect certain minority communities more severely. Rheumatic diseases may cause joint pain, stiffness or swelling. Some can involve bones, muscles, tendons or ligaments. Some cause abnormalities of the immune system-the body s defense against disease. Some rheumatic diseases are painful or deforming and some can be life threatening. Information obtained from this study will be used to learn about the disparities in rheumatic disease in the minority community and to design further, more targeted, research studies to address this issue. Patients with known or suspected rheumatic disease 18 years of age or older may be eligible for this study. Candidates will undergo a medical history and physical examination to confirm the diagnosis of rheumatic disease and determine what is needed for evaluation and treatment. Participants will receive standard medical care for rheumatic disease and arthritis. No experimental treatments, medications or procedures will be included in this study. Procedures may include routine blood tests for blood chemistries, cell counts, and antibodies commonly found in patients with rheumatic disease; a urine test for proteins and cells; and X-rays and other imaging tests to check for abnormalities in the lungs or other organs. All medical information will be kept confidential. Patients who are found to be eligible for other current NIH research studies will be offered an opportunity to participate in these studies....

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
