Diagnosis: Whenever possible, it is important to confirm the diagnosis of Wegener’s by biopsying an involved organ and finding the pathologic features of this disease under the microscope. Because many diseases may mimic Wegener’s (and vice versa), before starting a treatment regimen it is essential to be as certain of the diagnosis as possible.
Medications such as prednisone help suppress the immune system and treat the early signs and symptoms of Wegener's granulomatosis.
Most people require another immunosuppressive drug, such as cyclophosphamide, azathioprine or methotrexate, to counteract the body's immune reaction.
Statistics: Studies of Wegener's granulomatosis (WG) since the late 1980s indicate a probable increase in incidence of unknown cause and significance, possibly related to antineutrophil cytoplasmic antibody (ANCA) testing. In the population-based Swedish Inpatient Register, we identified 1938 individuals diagnosed with WG in the period 1975-2001, and calculated the annual age and sex adjusted incidences.
