What the study is about

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.

Conditions: Inflammation In Skeletal Muscle
