This case report details a 62-year-old woman diagnosed with Wegener Vasculitis, a form of ANCA-associated systemic vasculitis. Treatment with cyclophosphamide and prednisolone led to significant clinical improvement.

Area of Science:

  • Nephrology
  • Rheumatology
  • Immunology

Background:

  • Systemic vasculitis can present with diverse symptoms, often affecting multiple organs.
  • Wegener Vasculitis, now known as Granulomatosis with Polyangiitis (GPA), is a rare autoimmune disease characterized by inflammation of blood vessels.

Observation:

  • A 62-year-old woman with a history of hypertension presented with constitutional symptoms, anemia, hematuria, proteinuria, and renal failure.
  • Renal biopsy indicated chronic glomerulonephritis; however, clinical presentation and positive P-ANCA (Perinuclear Anti-Neutrophil Cytoplasmic Antibodies) suggested systemic vasculitis.
  • Subsequent development of maxillary sinusitis, nasal ulcers, and pneumonitis, despite non-granulomatous biopsy findings, supported the diagnosis of Wegener Vasculitis.

Findings:

  • The patient's presentation, including renal involvement and upper/lower respiratory tract inflammation, aligns with ANCA-associated systemic vasculitis.

Related Experiment Videos

  • The diagnosis was confirmed based on clinical criteria and serological markers (P-ANCA).

    • Implications:

    • This case highlights the importance of considering Wegener Vasculitis in patients with unexplained renal failure and multi-systemic inflammatory signs.
    • Effective treatment with immunosuppressive therapy (cyclophosphamide and prednisolone) can lead to favorable outcomes in ANCA-associated vasculitis.
    • The report contributes to the understanding of clinical classification criteria for ANCA-associated systemic vasculitis.
