Inflammatory Myopathy

Inflammatory myopathy (pronounced: in-flam-ma-tor-ee my-op-a-thee) is a group of diseases that involve chronic (long-term) muscle inflammation (myositis), accompanied by muscle weakness. The cause of much inflammatory myopathy is unknown (idiopathic).

Etymology

The term "Inflammatory myopathy" is derived from the Greek words "inflammatio" meaning inflammation, "myo" meaning muscle, and "pathos" meaning disease.

Types

There are three main types of inflammatory myopathies: Polymyositis, Dermatomyositis, and Inclusion body myositis.

  • Polymyositis affects the muscles closest to the center of the body, and is characterized by inflammation and progressive weakness.
  • Dermatomyositis is characterized by a skin rash preceding or accompanying progressive muscle weakness.
  • Inclusion body myositis is characterized by progressive muscle weakness and wasting, affecting both distal and proximal muscles.

Symptoms

Common symptoms of inflammatory myopathy include muscle weakness, fatigue, muscle pain, difficulty swallowing (dysphagia), and weight loss.

Diagnosis

Diagnosis of inflammatory myopathy is typically made through a combination of clinical examination, blood tests, muscle biopsy, and imaging studies.

Treatment

Treatment for inflammatory myopathy typically involves the use of medications to reduce inflammation and suppress the immune system, such as corticosteroids and immunosuppressive drugs. Physical therapy may also be beneficial.
