简要总结
Objective:
To collect information and biospecimens (such as blood, muscle, and skin samples) that will be used to research causes and treatments of inflammatory muscle diseases.
Eligibility:
People aged 2 years and older with suspected or confirmed inflammatory muscle disease. Healthy volunteers aged 18 years and older are also needed.
Design:
Participants will have at least 1 clinic visit. Each visit will last 4 to 8 hours. Some may return for additional visits.
All participants will undergo these procedures (unless they are unable to):
- Physical exam, including blood and urine tests.
- Magnetic resonance imaging (MRI) scan of the thigh. Participants will lie still on a table with padding around 1 thigh. The table will slide into a tube. The scan will last for approximately 40 minutes.
Some procedures are optional:
- Muscle biopsy: An area of skin will be numbed. A quarter-inch cut will be made. Several pieces of muscle tissue, about the size of grains of rice, will be removed.
- Skin biopsy: An area of skin will be numbed. A piece of skin about a quarter inch in diameter will be removed.
- Lymph node biopsy: A small sample of fluid or tissue from a lymph node will taken to check for infection.
- Genetic testing. Some of the samples collected may be used for genetic testing.
详细描述
Study Description:
This is an observational study to characterize the different types of inflammatory myopathies, understand their etiology, pathogenesis, prognosis, and response to different treatments.
Objectives:
Primary objective: Define the different types of inflammatory muscle diseases, their etiology, pathogenesis, prognostic factors, and response to different treatments.
Secondary objectives: Study different diagnostic modalities that may help to diagnose and monitor the evolution of the disease in patients with myositis.
