Granulomatosis with polyangiitis (GPA) is a multiorgan or systemic disease classified as a vasculitis. Typically people with GPA present in a hospital setting but sometimes are not as sick and will show up in the rheumatologist's office. The main problems with GPA are renal and lung so often referred to a renal-pulmonary syndrome.
Risk factors for relapse
Continue maintenance therapy for 24 to 36 months. Some experts would treat such patients indefinitely if the degree of organ damage was severe and a relapse would be poorly tolerated. [1]
