Since its first description by Wegener in 1936, Wegener's granulomatosis has undergone significant changes in terms of clinical scope, diagnosis, and treatment. It is no longer tenable to insist on the fulfillment of the Wegener's triad to make the diagnosis. The wide range of clinical presentations is encompassed by the ELK (ear, nose, and throat; lung; kidney) classification in which any combination or singular involvement of the major sites can be considered within the Wegener's spectrum if supported by the appropriate pathologic findings or the presence of a cytoplasmic antineutrophil cytoplasmic antibody pattern. Treatment is based on the extent of involvement and clinical tempo. Trimethoprim-sulfamethoxazole may be used for patients with localized disease. Systemic disease, including involvement of the kidney, mononeuritis multiplex, and skin vasculitis, is treated with systemic glucocorticoids and cyclophosphamide. Research into the antineutrophil cytoplasmic antibody phenomenon is yielding new insights into possible pathogenic mechanisms. |
