How is granulomatous vasculitis treated?
Vasculitis is a relatively common disease in modern society; however, some patients still lack sufficient understanding of it. So, how is granulomatosis with polyangiitis (GPA) treated?
How Is Granulomatosis with Polyangiitis Treated?
The primary treatment for granulomatosis with polyangiitis involves glucocorticoids combined with immunosuppressive agents. Combination therapy enhances efficacy and reduces the required glucocorticoid dose. Patients with concurrent infections also require prompt and aggressive antimicrobial therapy. During active disease phases, glucocorticoids—such as prednisone—are typically administered alongside cyclophosphamide. For severe cases—including central nervous system vasculitis, respiratory involvement with hypoxemia, or progressive renal failure—pulse-dose therapy (e.g., methylprednisolone) combined with cyclophosphamide is recommended. Close monitoring for adverse drug reactions—including bone marrow suppression, secondary infections, and peripheral leukopenia—is essential.

Granulomatosis with polyangiitis predominantly affects small- to medium-sized arteries and veins, producing diverse clinical manifestations across multiple organ systems. Involvement of the ear, nose, and throat may present as nasal crusting, sinusitis, otitis media, ear pain, persistent rhinorrhea, purulent or bloody nasal discharge, oral ulcers, or relapsing polychondritis. Respiratory tract and pulmonary involvement may cause hoarseness, cough, dyspnea, wheezing, and hemoptysis.

Renal involvement often manifests as asymptomatic hematuria—with or without elevated serum creatinine—and varying degrees of proteinuria. Cutaneous manifestations are highly variable; the most common finding is lower-limb palpable purpura, which may be associated with focal necrosis or ulceration. Other cutaneous features include urticaria, livedo reticularis, and subcutaneous nodules. We hope this information proves helpful to you!
