Objective: Granulomatous polyangiitis patients generally have ANCA targeting Proteinase 3 (PR3), while microscopic polyangiitis and eosinophilic granulomatous polyangiitis patients generally have ANCA targeting myeloperoxidase (MPO). Patients positive for both PR3-ANCA and MPO-ANCA are uncommon and any diagnostic value of this situation has not been well described. The aim of this study was to determine whether there were any patterns of clinical presentations or outcomes of patients who tested positive for both PR3-ANCA and MPO-ANCA. Methods: A retrospective clinical audit was carried out. A list of patients who had tested positive for both PR3- ANCA and MPO-ANCA was obtained from ACT Pathology from 2003-2013. Medical records were then used to determine their clinical outcomes. Results: 3 of the 15 study patients we.. View More»
