Granulomatosis With Polyangiitis: Cardiac, Renal, and Respiratory Involvement

Area of Science:

• Nephrology
• Rheumatology
• Pulmonology

Background:

• Granulomatosis with polyangiitis (GPA), previously Wegener's granulomatosis, is an anti-neutrophilic cytoplasmic autoantibody (ANCA)-associated small-vessel vasculitis.
• GPA typically manifests as necrotizing granulomatous inflammation in the respiratory tract and necrotizing glomerulonephritis.

Observation:

• A male patient in his 60s presented with a complex clinical scenario.
• The patient experienced rapidly progressive renal failure necessitating dialysis.
• He also developed diffuse alveolar hemorrhage, acute respiratory distress syndrome (ARDS), circulatory shock, pulmonary embolism, and biventricular dilated cardiomyopathy.

Findings:

• This case illustrates the severe and multi-systemic impact of GPA.
• The patient's presentation included critical cardiorespiratory and renal complications.
• Diagnosis was supported by clinical presentation, antibody testing, imaging, and kidney biopsy.

Implications:

• Early recognition and aggressive management are crucial for patients with severe GPA.
• Understanding GPA's potential for rapid, life-threatening complications is vital for clinicians.
• This case underscores the importance of a multidisciplinary approach in managing complex vasculitis cases.
