The purpose of this study is to identify genes that increase the risk of developing vasculitis, a group of severe diseases that feature inflammation of blood vessels. 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.

Detailed Description:

The systemic vasculitides comprise several inflammatory diseases of blood vessels, usually arteries, which may cause systemic, multi-organ disease that can result in substantial morbidity and increased mortality. Each type of vasculitis is a rare ("orphan") disease. 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. 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. The Vasculitis Clinical Research Consortium (VCRC) currently focuses on 6 specific types of vasculitis that were selected to represent a balance between unmet medical and scientific needs, prevalence in North America, feasibility of study, and an interest in studying a spectrum of small, medium, and large vessel vasculitides.

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. Larger and more ambitious genetic studies in vasculitis are expected to generate numerous hypotheses for translational research in gene expression, biochemistry, and molecular pathology.

A one-time collection of clinical data and DNA would substantially increase the sample sizes for genetic association studies in all six vasculitides studied in the VCRC. Many patients are seen at participating VCRC centers but do not enroll in the Longitudinal Studies. These patients often are interested in participating in research studies but cannot return frequently for visits, usually due to distance from the VCRC centers. This approach would be particularly useful for the rarer forms of vasculitis under study (Takayasu's Arteritis (TAK), Polyarteritis Nodosa (PAN), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (EGPA) and also for Giant Cell Arteritis (GCA), since elderly patients have been particularly likely to decline participation in the Longitudinal Studies due to travel constraints.

Inclusion Criteria:

4. Diagnostic criteria for Granulomatosis with Polyangiitis (Wegener's) (GPA) and Microscopic Polyangitis (MPA)

  • Diagnosis of GPA or MPA. Widely accepted diagnostic criteria, as opposed to classification criteria or definitions, have not been developed for GPA & MPA.
  • For diagnosis of GPA meets at least 2 of the following 5 modified ACR criteria:

    1. Nasal or oral inflammation with oral ulcers or nasal discharge with pus or blood
    2. Abnormal chest radiograph with nodules, fixed infiltrates, or cavities
    3. Urinary sediment with microhematuria or red cell casts
    4. Granulomatous inflammation within the wall of an artery or in the perivascular area on biopsy
    5. Antineutrophil cytoplasmic antibody (ANCA) positive by enzyme immunoassay for either PR3- or MPO-ANCA
  • For diagnosis of MPA, meets the Chapel Hill Consensus Conference Definition for MPA:

    1. Necrotizing vasculitis, with few or no immune deposits, that affects small vessels (i.e., capillaries, venules, arterioles)
    2. Necrotizing arteritis involving small- and medium-sized arteries may be present
    3. Necrotizing glomerulonephritis is very common
    4. Pulmonary capillaritis often occurs

      Inclusion Criteria:

      5. Diagnostic criteria for Eosinophilic Granulomatosis with Polyangiitis (Churg-Strauss)

      1. Asthma
      2. Peak peripheral blood eosinophilia of >10% of total WBC
      3. Peripheral neuropathy attributable to vasculitis
      4. Transient pulmonary infiltrates on chest imaging studies
      5. Paranasal sinus abnormalities or nasal polyposis
      6. Eosinophilic inflammation on tissue biopsy

      If patients have 4 of the above 6 criteria but lack clearcut documentation of small vessel vasculitis, they are also eligible for enrollment.

      General Exclusion Criteria:

  • Inability to give informed consent and to sign the consent form
  • Enrolled in VCRC protocols 5502, 5503, 5504, 5505, 5506, 5522, or 5523
  • Unwilling to provide blood for DNA collection
