Descriptive Information
Brief Title MICRO-RNAs OF NEUTROPHILS IN RENAL ANTINEUTROPHIL CYTOPLASMIS ANTIBODY (ANCA) -ASSOCIATED VASCULITIS
Official Title MICRO-RNAs OF NEUTROPHILS IN RENAL ANCA-ASSOCIATED VASCULITIS
Brief Summary Activation of neutrophils by ANCA ("Anti-Neutrophil Cytoplasm Antibodies") and subsequent microvascular endothelial cell damage is the main feature of ANCA-associated vasculitis (AAV), a severe autoimmune disease that often targets the kidney. There is no specific treatment for AAV to date and 25% of patients with renal damage evolve towards end-stage renal disease, requiring dialysis and kidney transplantation. In addition, there is no reliable biological marker of the disease activity available, which makes the diagnostic, follow-up and treatment of patients difficult. Therefore, the identification of new therapeutic targets and non-invasive biomarkers constitutes a major clinical challenge to improve AAV patients care and to ameliorate their renal outcome.
Detailed Description Not Provided
Study Type Observational
Study Design Observational Model: Case-Control
Time Perspective: Prospective
Target Follow-Up Duration Not Provided
Biospecimen Retention:   Samples Without DNA
Description:
50 mL of blood and 10 mL of urine by patient
Sampling Method Non-Probability Sample
Study Population This will be done in total in 50 patients with ANCA-associated vasculitis (AAV) and 20 control patients. Among the 50 patients with AAV, 30 patients will be newly diagnosed and 20 already followed for AAV
Condition ANCA-associated Vasculitis
Intervention Other: Non interventional study
This is a non interventional study because all levies are performed during visit planned for the care of patients.
Study Groups/Cohorts
  • Group AAV
    Patients recruited from the Nantes University Hospital. 50 milliliter of blood and 10mL of urine are collected from these patients during levies in clinical visit.
    Intervention: Other: Non interventional study
  • Group control

    People recruited from the "Etablissement français du sang" (French blood establishment ).

    10 milliliter of blood are collected from these donors

    Intervention: Other: Non interventional study
Publications * Not Provided

*   Includes publications given by the data provider as well as publications identified by ClinicalTrials.gov Identifier (NCT Number) in Medline.
