Wegener's granulomatosis overview


 * Associate Editor-In-Chief:

Overview
Wegener's granulomatosis is a form of vasculitis that affects the lungs, kidneys and other organs. Due to its end-organ damage, it can be a serious disease that requires long-term immune suppression. It is named after Dr. Friedrich Wegener, who described the disease in 1936.

Wegener's granulomatosis is part of a larger group of vasculitic syndromes, all of which feature the presence of an abnormal type of circulating antibody termed ANCAs (antineutrophil cytoplasmic antibodies) and affect small and medium-size blood vessels. Apart from Wegener's, this category includes Churg-Strauss syndrome and microscopic polyangiitis. Although Wegener's granulomatosis affects small and medium-sized vessels, it is formally classified as one of the small vessel vasculitides in the Chapel Hill system.
