Wegener's granulomatosis can mimic sepsis and ARDS, complicating diagnosis in critically ill patients. Early diagnosis and immunosuppressive therapy are crucial for recovery from this rare multisystem vasculitis.

Area of Science:

  • Nephrology
  • Pulmonology
  • Rheumatology

Background:

  • Wegener's granulomatosis is a rare autoimmune disease causing granulomatous vasculitis affecting the respiratory tract and kidneys.
  • It can present with symptoms mimicking sepsis and acute respiratory distress syndrome (ARDS), posing diagnostic challenges.

Observation:

  • A 19-year-old female presented with acute respiratory and renal failure, initially treated for sepsis and managed with extracorporeal membrane oxygenation (ECMO).
  • Deterioration upon hydrocortisone tapering, coupled with renal biopsy findings and positive anti-proteinase 3 antibodies (PR3-ANCA), indicated Wegener's granulomatosis.

Findings:

  • Diagnosis was confirmed by renal biopsy showing vasculitis and glomerulonephritis, positive PR3-ANCA, and multisystem involvement.
  • Prompt immunosuppressive therapy with cyclophosphamide and prednisolone led to rapid recovery of pulmonary, renal, and neurological functions.

Implications:

  • This case highlights the importance of considering rare conditions like Wegener's granulomatosis in the differential diagnosis of ARDS and sepsis.
  • Intensive care physicians must be aware of Wegener's granulomatosis to avoid misdiagnosis and delayed, potentially harmful treatments.
