    Abstract Necrotizing vasculitis of small blood vessels is a rare condition, but when it affects important organs it can lead to life-threatening organ damage and death. Thus, recognizing these conditions at an early stage before they spread to become systemic is a constant challenge to clinical medicine. The objectives of this review are: to give advice on clinical indications for ANCA diagnostics and laboratory procedures for highly specifically detecting the most important ANCA; to provide some data on the autoantigens involved in ANCA reactivity in small vessel vasculitides; and to discuss at the occurrence of ANCA in different vasculitic populations and at different stages of disease. One important task for the near future will be to standardize the assays used for ANCA detection/quantification and to harmonize the results given to clinicians by ensuring that international reference reagents are used by laboratories and the diagnostic industry. Finally, the author has attempted to summarize the role that ANCA are currently believed to play in the immuno-inflammatory events that take place in tissues and that affect small vessels in idiopathic vasculitis. The review concludes that the presence of ANCA is likely to become an important criterion for diagnosing idiopathic small vessel vasculitis.

    Abstract Purpose of review: This review aims to draw attention to the features that distinguish drug-induced vasculitis and drug-induced lupus-like disease from those of idiopathic autoimmune syndromes, first and foremost primary vasculitides and systemic lupus erythematosus. Drug-induced vasculitis and drug-induced lupus-like disease are seen in patients treated long term with a drug, and close to 100 drugs representing all pharmacologic classes have been assumed capable of inducing such syndromes. The clinical phenotypes vary from single tissue or organ involvement to severe systemic inflammatory disease dominated by vasculitis and sometimes organ failure.
    Recent findings: The recent discovery of antineutrophil cytoplasm antibodies in a large serological subset of drug-induced vasculitis/drug-induced lupus-like disease caused by long-term antithyroid drug treatment has opened new avenues for differential diagnostics. Antineutrophil cytoplasm antibodies with specificity to more than one lysosomal antigen, combined with presence of antibodies to histones and beta-2 glycoprotein 1 constitute a unique serological profile for drug-induced vasculitis/drug-induced lupus-like disease.
    Summary: Rational use of laboratory marker profiles is likely to aid in distinguishing drug-induced from idiopathic syndromes. Hence, the use of antineutrophil cytoplasm antibodies and other autoantibodies as biomarkers of different phenotypes of drug-induced vasculitis/drug-induced lupus-like disease is the main focus of this review.

    Abstract Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitides are systemic or more limited conditions characterized by necrotizing destruction of small and medium-sized vessels (eg, capillaries, venules, and arterioles). ANCAs are the most predominant autoantibodies in patients affected by vasculitis, but other autoantibodies may also occur, probably reflecting pathogenetic events in affected tissue. These autoantibodies are assumed to play a role in the initiation and propagation of chronic inflammation. ANCAs are valuable for clinical diagnosis, follow-up, and guidance in therapy.

    Abstract Clinical recognition of drug-induced vasculitic and lupus-like syndromes is very important because continued use of the offending drug can lead to irreversible and life-threatening vasculitic organ damage (e.g. end-stage renal disease or pulmonary haemorrhage). Withdrawal of the drug often leads to spontaneous recovery, meaning that immunosuppressive therapy can be avoided. The presence of myeloperoxidase-antineutrophil cytoplasmic antibodies, IgM anticardiolipin antibody, and antihistone antibodies in combination was found to be characteristic of drug-induced vasculitic syndromes caused by the antithyroid drugs propylthiouracil and methimazol. Clinically, skin vasculitis and arthralgias predominated and renal vasculitis was rare.

    Abstract This article reviews data concerning the applicability of anti-citrullinated peptide antibodies in the diagnosis, estimation of prognosis, and follow-up of patients with rheumatoid arthritis (RA). The production of anti-citrullinated peptide antibodies is closely associated with the presence of the HLA-DRB1 shared epitope, a known risk factor for development of RA, and the production may be influenced by environmental factors such as tobacco smoking. Patients who harbor this antibody from the early stage of their disease develop more severe erosive disease than patients with RA who lack the antibody. The anti-citrullinated peptide antibody level may be a reflection of disease activity, at least in the early phase of the disease. The antibody can sometimes be found several years before the onset of clinical symptoms of RA, which may represent an open window for preventive measures to be taken.

    Abstract Before the mid-1980s the only autoantibody widely used to assist in diagnosing vasculitic disease was IgG antibody to the alpha(3) domain of the noncollagenous part of type IV collagen (anti-glomerular basement membrane). Since that time, antineutrophil cytoplasmic antibodies (ANCAs) directed at the azurophilic granule proteins proteinase-3 and myeloperoxidase have been established as clinically useful autoantibodies to support a diagnosis of Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome and limited forms of these primary, small vessel necrotizing and often granulomatous vasculitides. The establishment of standardized methods for identifying those antibodies was needed before they could be used in clinical practice. The levels of both types of ANCAs tend to increase in parallel with the degree of clinical disease activity, and they decrease with successful immunosuppressive therapy. More than one assay may have to be used to discover imminent exacerbations in proteinase-3-ANCA associated syndromes. Although autoantibodies to endothelial cells may be important players in the pathogenesis of several vasculitic conditions, they have not gained clinical popularity because of lack of standardized detection methods.

    Abstract This review intends to highlight important differences between neutrophil-specific autoantibodies (NSA) typically found in chronic inflammatory bowel diseases (CIBD) and anti-neutrophil cytoplasm antibodies (ANCA) associated with primary systemic small vessel vasculitides (SSVV). Indirect immunofluorescence (IF) techniques alone cannot distinguish NSA from ANCA and special measures must be taken to separate these two autoantibody populations. Many autoantigens originating in all cell compartments may be targeted by NSA in CIBD, several of these being constituents of neutrophil nuclei. Apart from the use of NSA in the differential diagnosis between Crohn's disease (CD) and ulcerative colitis (UC), very limited clinical significance is ascribed to these antibodies in CIBD. Laboratory reports on NSA-positivity must be clearly distinguishable from reports on ANCA to help avoid clinical misinterpretation.

    Abstract In this essay we describe a number of the known and not so known experiences of the early anti-neutrophil cytoplasmic antibodies (ANCAs) days, explaining why and how we reached consensus on the standard indirect immunofluorescence (IIF) techniques, the naming of the two principal C- and P-ANCA patterns, why we chose to use IIF as the standard technique, how the solid phase assays have developed and where we stand today, the use of ANCA for diagnosis and the importance of using several techniques for that purpose, how ANCA titres are related to disease activity and the clinical impact of this, and finally the implications of ANCA being a natural, polyclonal antibody response against various epitopes in relation to diagnostics and disease patterns.
