This case report highlights a rare complication of microscopic polyangiitis (MPA). Autopsy revealed severe pancreatic vasculitis, emphasizing the need for clinicians to consider pancreatic involvement in MPA patients.

Area of Science:

  • Nephrology
  • Pathology
  • Rheumatology

Background:

  • Microscopic polyangiitis (MPA) is a rare autoimmune disease characterized by inflammation of small blood vessels.
  • Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, particularly anti-myeloperoxidase (MPO) ANCA, can affect multiple organs.

Observation:

  • An 84-year-old woman with MPO-ANCA-related MPA presented with fever and progressive renal failure.
  • Despite successful initial treatment with prednisolone, the patient later experienced cardiac arrest and died.
  • Autopsy revealed systemic vasculitis with fibrinoid necrosis, most severely affecting the pancreas, alongside interstitial pneumonia and crescentic glomerulonephritis.

Findings:

  • Pancreatic involvement, manifesting as severe vasculitis and fibrinoid necrosis, was identified as a significant finding in this MPA case.

Related Experiment Videos

  • This represents the first reported case focusing specifically on pancreatic involvement as a complication of MPA.

    • Implications:

    • Nephrologists should consider pancreatic involvement in the differential diagnosis of patients with microscopic polyangiitis.
    • Early recognition and management of pancreatic complications may improve outcomes in MPA patients.
