Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis: Group of systemic vasculitis with a strong association with ANCA. The disorders are characterized by necrotizing inflammation of small and medium size vessels, with little or no immune-complex deposits in vessel walls.Vasculitis: Inflammation of any one of the blood vessels, including the ARTERIES; VEINS; and rest of the vasculature system in the body.Antibodies, Antineutrophil Cytoplasmic: Autoantibodies directed against cytoplasmic constituents of POLYMORPHONUCLEAR LEUKOCYTES and/or MONOCYTES. They are used as specific markers for GRANULOMATOSIS WITH POLYANGIITIS and other diseases, though their pathophysiological role is not clear. ANCA are routinely detected by indirect immunofluorescence with three different patterns: c-ANCA (cytoplasmic), p-ANCA (perinuclear), and atypical ANCA.Microscopic Polyangiitis: A primary systemic vasculitis of small- and some medium-sized vessels. It is characterized by a tropism for kidneys and lungs, positive association with anti-neutrophil cytoplasmic antibodies (ANCA), and a paucity of immunoglobulin deposits in vessel walls.Wegener Granulomatosis: A multisystemic disease of a complex genetic background. It is characterized by inflammation of the blood vessels (VASCULITIS) leading to damage in any number of organs. The common features include granulomatous inflammation of the RESPIRATORY TRACT and kidneys. Most patients have measurable autoantibodies (ANTINEUTROPHIL CYTOPLASMIC ANTIBODIES) against neutrophil proteinase-3 (WEGENER AUTOANTIGEN).Antibodies, Monoclonal, Murine-Derived: Antibodies obtained from a single clone of cells grown in mice or rats.Remission Induction: Therapeutic act or process that initiates a response to a complete or partial remission level.Peroxidase: A hemeprotein from leukocytes. Deficiency of this enzyme leads to a hereditary disorder coupled with disseminated moniliasis. It catalyzes the conversion of a donor and peroxide to an oxidized donor and water. EC 1.11.1.7.Churg-Strauss Syndrome: Widespread necrotizing angiitis with granulomas. Pulmonary involvement is frequent. Asthma or other respiratory infection may precede evidence of vasculitis. Eosinophilia and lung involvement differentiate this disease from POLYARTERITIS NODOSA.Immunosuppressive Agents: Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.Recurrence: The return of a sign, symptom, or disease after a remission.Glomerulonephritis: Inflammation of the renal glomeruli (KIDNEY GLOMERULUS) that can be classified by the type of glomerular injuries including antibody deposition, complement activation, cellular proliferation, and glomerulosclerosis. These structural and functional abnormalities usually lead to HEMATURIA; PROTEINURIA; HYPERTENSION; and RENAL INSUFFICIENCY.Prednisolone: A glucocorticoid with the general properties of the corticosteroids. It is the drug of choice for all conditions in which routine systemic corticosteroid therapy is indicated, except adrenal deficiency states.Myeloblastin: A polymorphonuclear leukocyte-derived serine protease that degrades proteins such as ELASTIN; FIBRONECTIN; LAMININ; VITRONECTIN; and COLLAGEN. It is named for its ability to control myeloid cell growth and differentiation.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.

A 70-year-old woman with a history of end-stage renal disease secondary to anti-neutrophil cytoplasmic autoantibody-associated vasculitis had been receiving hemodialysis for 5 years. The patient underwent attempted right internal jugular vein cannulation for temporary hemodialysis catheter placement. Pulsating mass developed in the neck and angiography revealed a subclavian artery pseudoaneurysm 4 days later. The pseudoaneurysm disappeared spontaneously during the interval between the diagnosis and the planned surgical procedure. Such delayed onset and spontaneous resolution of subclavian artery pseudoaneurysm is uncommon. Close observation may be optimal if delayed onset of pseudoaneurysm occurs after small needle puncture with cessation of antiplatelet/anticoagulant administration.  (+info)

  • pathogenesis
  • A recent genome-wide association study of patients with ANCA-associated vasculitides confirmed the genetic contribution to the pathogenesis of these conditions, with significant association of PR3-ANCA and human leukocyte antigen-DP and the genes encoding α1-antitrypsin and PR3. (bmj.com)
  • While the vasculitides share the trait of vascular inflammation, the unique disease phenotypes, clinical courses, differences in prognoses, and responses to therapy suggest that important differences exist in pathogenesis. (clinicaltrials.gov)
  • cutaneous
  • Arthritis: Pain or swelling (60%), often initially diagnosed as rheumatoid arthritis Skin: nodules on the elbow, purpura, various others (see cutaneous vasculitis) Nervous system: occasionally sensory neuropathy (10%) and rarely mononeuritis multiplex Heart, gastrointestinal tract, brain, other organs: rarely affected. (wikipedia.org)
  • If the person has kidney failure or cutaneous vasculitis, a biopsy is obtained from the kidneys. (wikipedia.org)
  • autoimmune
  • Results of these studies will provide vasculitis researchers with insight into the causes of these diseases and generate new ideas for diagnostic tests and therapies, and will be of great interest to the larger communities of researchers investigating vasculitis and other autoimmune, inflammatory, and vascular diseases. (clinicaltrials.gov)
  • They are detected as a blood test in a number of autoimmune disorders, but are particularly associated with systemic vasculitis, so called ANCA-associated vasculitides. (wikipedia.org)
  • protein
  • The antibodies are directed against a particular protein found in the GBM, type IV collagen, specifically the noncollagenous region of its α3 chain. (wikipedia.org)
  • vascular
  • Other more recent reports of widespread livedo and acral purpura due to vascular coagulation similar to that seen in livedoid vasculitis but with a much more rapid, widespread and intense onset have been linked to cocaine laced with levamasole. (oncologynurseadvisor.com)
  • affects
  • However, taken together, vasculitis affects tens of thousands of Americans and is responsible for substantial morbidity and mortality and almost one billion dollars per year in hospital care alone. (clinicaltrials.gov)
  • inflammatory
  • Neutrophil apoptosis, or programmed cell death, is vital in controlling the duration of the early inflammatory response, thus restricting damage to tissues by the neutrophils. (wikipedia.org)
  • These antibodies will circulate at low levels until a pro-inflammatory trigger - such as infection, malignancy, or drug therapy. (wikipedia.org)
  • nomenclature
  • In 1994, Falk and Jennette convened an International Consensus Conference that yielded the Chapel Hill Nomenclature for Small Vessel Vasculitis that has now been adopted on a worldwide basis. (wikipedia.org)
  • Nearly two decades later, clinicians and scientists from numerous disciplines were invited to Chapel Hill to revisit the nomenclature and participate in the 15th International Vasculitis & ANCA workshop. (wikipedia.org)
  • genetic
  • Larger and more ambitious genetic studies in vasculitis are expected to generate numerous hypotheses for translational research in gene expression, biochemistry, and molecular pathology. (clinicaltrials.gov)
  • known
  • Also known as pauci-immune RPGN, type III RPGN accounts for 55% of RPGN and features neither immune complex deposition nor anti-GBM antibodies. (wikipedia.org)
  • mice
  • In vivo data are available for humans and mice on the pathogenicity of anti-MPO but it is more controversial for PR3-ANCA. (bmj.com)
  • studies
  • The great majority of published studies on the genetics of vasculitis have used modest-sized cohorts that are only suitable for investigation of a few candidate genes at a time, or to detect large effect sizes, so that replicated findings are highly skewed to the HLA region. (clinicaltrials.gov)
