Myositis
Call for an AppointmentSpecialists in Duke’s nationally ranked rheumatology center diagnose and manage treatment of myositis, a group of diseases characterized by muscle inflammation. Our experienced rheumatologists collaborate with other Duke specialists to relieve the muscle weakness and fatigue associated with myositis and help you return to an active lifestyle.
About Myositis
Myositis is caused by inflammation in the muscles. It includes polymyositis, which primarily causes muscle weakness, and dermatomyositis, which involves both skin rashes and muscle weakness.
Inclusion-body myositis is characterized by gradual muscle weakness throughout the body, while polymyositis primarily involves weakness in the muscles in the body’s middle section.
Inflammatory myositis may be linked to other autoimmune conditions -- including lupus, scleroderma, and rheumatoid arthritis -- and may cause complications such as difficulty breathing or swallowing. As a result, we take a comprehensive approach to treatment that draws upon the experience of specialists throughout Duke. Our goal is to provide you the best care for your individual needs.

Tests
If you have muscle weakness or other symptoms that may indicate myositis, our experienced doctors will carefully review your medical history and perform a complete physical exam to make a definitive diagnosis. Your evaluation may include:
Blood Tests
Your doctor may order blood tests that measure elevated levels of muscle enzymes and rheumatoid factors such as antibodies and proteins.
Electromyogram (EMG)
A small metal needle inserted through the skin and into the muscles records impulses or electrical activity that pinpoint damage or weakness.
MRI
MRI images can show signs of muscle damage.
Muscle Biopsy
The doctor removes a small sample of muscle tissue to be examined under a microscope for signs of myositis.
Skin Biopsy
The doctor removes a small sample of skin tissue to be examined under a microscope to help diagnose dermatomyositis.
