Granulomatosis With Polyangiitis (GPA) Causes, Symptoms, Diagnosis And Treatment

Granulomatosis With Polyangiitis

What Is GPA?

Granulomatosis with polyangiitis or GPA is a serious condition which is known to cause tissue damage.

Formerly referred as Wegener’s granulomatosis, GPA is a systemic disorder which involves both granulomatosis and polyangiitis. A systemic disorder entails inflammation that is present in the entire body.

It is a form of vasculitis, which may affect lungs, respiratory system, kidneys, ears, throat, skin and other organs.

Those whose kidney, brain or gut is not affected in GPA are said to suffer from limited GPA. However, the word ‘limited’ has misleading connotations since it seems to imply that the condition is not serious when in reality the other symptoms may be dangerous enough to prove to be fatal.

A rare disease, GPA can occur in any age. However, it generally occurs to those between the age of 40 and 50.

In recent years, the awareness regarding GPA has grown immensely. This has lead to better diagnoses which may prevent organ failure.

The presence of effective treatment also ensures a relatively normal life for those affected.
