Anti-neutrophil cytoplasmic antibodies (ANCA) are the hallmark of the so-called ANCAassociated vasculitides (AAV) (Jennette & Falk, 1997). These primary small-vessel vasculitides comprise granulomatosis with polyangiitis (GPA, previously referred to as Wegener’s granulomatosis) (Falk et al, 2011), the Churg-Straus syndrome (CSS), microscopic polyangiitis (MPA), and renal-limited necrotizing cre...
Antineutrophil cytoplasmic antibodies (ANCA) of IgG class have been described at high prevalence in autoimmune hepatitis (AIH) and primary sclerosing cholangitis (PSC). Data on IgA class ANCA in these diseases are limited. The aim of this study was to determine the prevalence and fluorescence patterns of IgA class ANCA in AIH and PSC and to examine a relationship between the presence of IgA ANC...
OBJECTIVES Pentraxin 3 (PTX3), in common with myeloperoxidase and proteinase 3, is stored in human neutrophil granules and is expressed on apoptotic neutrophil surface. We therefore investigated the presence of anti-PTX3 autoantibodies (aAbs) in the sera of antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) patients. METHODS Presence of anti-PTX3 autoantibodies was analy...
Background: Inflammatory bowel disease unclassified (IBDU) is considered to be an aberrant immune response with loss of tolerance to many antigens. Objective: This paper tries to address whether there is any value to test for auto-antibodies in such patients. Methods: 60 patients with inflammatory bowel disease unclassified participated in the study. Auto-antibodies to nuclear antigen, intestin...

OBJECTIVES To investigate whether discriminating the classic perinuclear antineutrophil cytoplasmic antibody (P-ANCA) pattern from atypical P-ANCA and uninterpretable patterns improves the diagnostic utility of ANCA testing. METHODS All ANCA requests (n = 3,544) referred to Pathology Queensland were analyzed prospectively over 4 months for P-ANCA pattern subtypes and myeloperoxidase (MPO)-ANC...
Primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) are enigmatic chronic inflammatory diseases of the liver, which are frequently associated with chronic inflammatory bowel diseases. Both types of liver disease share various distinct autoantibodies such as atypical perinuclear antineutrophil cytoplasmic antibodies (p-ANCA), and thus are considered autoimmune disorders with atyp...
BACKGROUND AND OBJECTIVES Mycobacterial infections are known to induce the development of autoantibodies and a few of these antibodies are also known to be diagnostic markers for some other diseases and it is uncertain whether these autoantibodies play a role in the pathogenesis of autoimmune disorders. This study was undertaken to determine the prevalence of autoantibodies like anti-neutrophil...
