What is microscopic polyangiitis?

Microscopic polyangiitis refers to the condition that causes blood vessel inflammation (vasculitis), which can lead to organ damage. The exact cause is unclear. What’s clear is that it is not a form of cancer. Nor is it contagious.

Mostly, it affects kidneys, lungs, nerves, skin, and joints.

The symptoms depend on where is affected. In general, patients experience:

  • Fatigue
  • Fevers
  • Loss of appetite and weight
  • Muscle/joint pain
  • Nerve damage
  • Skin lesions
  • Shortness of breath or coughing up of blood (when it affects the lungs)

Sometimes, there are even no symptoms until the organ (such as kidney) stops to work. Therefore, if you’re worried, you need to consult your doctor for details and undergo urine tests and other examinations to determine the condition.

Treatment for this disorder usually involves medications like corticosteroids and cyclophosphamide.
