Antineutrophil cytoplasmic antibodies (ANCA) are well known to be associated with small vessel vasculitic diseases such as microscopic polyangiitis (MPA), allergic granulomatous angiitis (AGA), and Granulomatosis with poly angiitis: GPA (Wegener's). Disease assessment by 1) vasculitic activity, 2) damage resulting from vasculitis, and 3) patient function, were the required endpoints for the therapeutic trials in ANCA- associated vasculitis (AAV). Harmonized steroids and cyclophosphamide or azathioprine are effective for active AAV. In evaluating tools for monitoring disease, titers of ANCA and the levels of CRP were found useful in AAV. However, it will be important for clinicians to observe AAV patients more closely and reduce immunosuppressive drug doses more cautiously, especially to prevent several infections (i.e., deep mycosis, pneumocystis jirovecii pneumonia and cytomegalovirus). We indicated that strategy of infection control in immunosuppressive therapy for AAV. (J Jpn Coll Angiol, 2009, 49: 93-99)
