A Case of an Elderly Woman Who Developed Corneal Perforation in the Clinical Course of Myeloperoxidase Positive Antineutrophil Cytoplasmic Antibody-Associated Vasculitis

Figure 1

Clinical course of MPO-ANCA and C-reactive protein. During her clinical course, AAV and scleritis relapsed twice, at 65 months and 53 months before the current admission. At 65 and 53 months before the current admission, the MPO-ANCA titer was in the positive range and obviously increased, and C-reactive protein levels were also increased, although the C-reactive protein level was low, at less than 1.0 mg/dL (green circle). At the time of admission, C-reactive protein levels did not obviously increase (green circles). In addition, although the MPO-ANCA titer at the time of admission was positive, the titer was not obviously increased compared to the levels over the previous several months.
