This case study highlights ANCA-positive vasculitis presenting as acute renal failure in an elderly male. Early recognition of renal deterioration is crucial for diagnosing vasculitis and avoiding misdiagnosis of other conditions.

Area of Science:

  • Nephrology
  • Rheumatology
  • Geriatrics

Background:

  • Vasculitis is increasingly diagnosed in the elderly population.
  • Elderly patients often present with non-specific symptoms, complicating diagnosis.
  • Acute renal failure (ARF) in the elderly requires careful differential diagnosis.

Observation:

  • An 84-year-old male presented with weight loss, low-grade fever, anemia, and epigastric pain.
  • Initial diagnosis was suspected digestive neoplasia.
  • Progressive renal insufficiency developed after 14 days, leading to the identification of ANCA-positive vasculitis.

Findings:

  • The patient's clinical presentation was attributed to Antineutrophil Cytoplasmic Antibody (ANCA)-positive vasculitis.
  • The case illustrates the diagnostic challenge of non-oliguric acute renal failure in older individuals.

  • Acute deterioration of renal function served as a critical indicator for re-evaluating the clinical data.

    • Implications:

    • Emphasizes the importance of considering vasculitis in the differential diagnosis of unexplained renal failure in the elderly.
    • Highlights the need for systematic evaluation of renal insufficiency, especially in patients with unknown baseline renal function.
    • A focused pursuit of alternative diagnoses, like malignancy, can delay the identification of underlying vasculitis.
