Cavitary lung lesions carry a broad differential diagnosis. Even in patients who have a firmly established diagnosis of GPA, cavities may have other causes, and a thorough assessment of other organ sites is warranted.
Identifying reliable biomarkers of disease activity in granulomatosis with polyangiitis is the goal of a collaboration between Cleveland Clinic and Case Western Reserve University
Study findings support the addition of a conventional maintenance agent, in the absence of contraindications, with rituximab to reduce the risk of relapse in granulomatosis with polyangiitis patients.
GPA (Wegener’s) characteristically has a relapsing course, and studies support continuing maintenance medications for at least 36 months.

Addition of a conventional maintenance agent to rituximab and glucocorticoids reduced the incidence of GPA relapse without resulting in a higher incidence of adverse events in study.
