Nevertheless, necrotizing granulomas are a hallmark of this disease. However, many biopsies can be nonspecific and 50% provide too little information for the diagnosis of GPA. 140:
and a form of vasculitis that affects small- and medium-size vessels in many organs but most commonly affects the upper respiratory tract, lungs and kidneys. The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels. Typical signs and symptoms

In generalized non-organ-threatening disease, remission can be achieved with a combination of methotrexate and corticosteroids, where the steroid dose is reduced after a remission has been achieved and methotrexate is used as maintenance therapy. Treatment measures for localised GPA of the nose and

Rituximab may be substituted for cyclophosphamide to induce remission since it is similarly effective and has a comparable side effect profile. The dose of corticosteroids is generally tapered (decreased) very slowly over the course of several months to reduce the risk of another GPA flare. After a

Oral and intravenous cyclophosphamide are both effective for induction of GPA remission. Oral cyclophosphamide at a dose of 2 mg/kg/day was the standard treatment for many years; this regimen resulted in complete remission in more than 75% of people with GPA but is associated with significant

Today, medication toxicity is managed more carefully and long-term remissions are possible. Some affected individuals are able to lead relatively normal lives and remain in remission for 20+ years after treatment.
