This case study details a patient with polyangitis overlap syndrome, a rare condition causing multi-system vasculitis. Early diagnosis and treatment are crucial for managing this severe autoimmune disorder.

Area of Science:

  • Rheumatology
  • Internal Medicine
  • Pathology

Background:

  • A 45-year-old woman with a history of smoking, hypertension, and myocardial infarction presented with critical limb ischemia.
  • Initial symptoms included cold paresthesias, fingertip pain, and acral necroses, alongside evidence of bilateral digital and internal carotid artery occlusions.

Observation:

  • The patient exhibited elevated inflammatory markers (ESR 101/130 mm) and responded temporarily to rheological treatment and methylprednisolone.
  • Further complications arose, including abdominal pain, intermittent claudication, hemoptysis, pulmonary reticular shadows, and acute kidney injury (creatinine 5.5 mg/dl).

Findings:

  • Histological examination confirmed vasculitis, and high titers of cytoplasmic antineutrophil cytoplasmic antibodies (cANCA) were detected.

  • Despite aggressive immunosuppressive therapy with cyclophosphamide and glucocorticoids, the patient experienced worsening renal failure, stroke, and angina.

    • Implications:

    • This case highlights the complex and severe presentation of polyangitis overlap syndrome, a challenging diagnosis.
    • The patient's rapid decline and fatal outcome underscore the critical need for prompt recognition and multidisciplinary management of systemic vasculitis.
