Pulmonary disease in Behçet's syndrome

Area of Science:

• Rheumatology
• Pulmonology
• Immunopathology

Background:

• Behçet's syndrome is a multisystem vasculitis.
• Pulmonary involvement is a rare but serious complication.

Observation:

• A review of 28 cases of Behçet's syndrome with haemoptysis revealed a distinct clinical pattern.
• Haemoptysis, often with pyrexia, chest pain, and dyspnoea, was the predominant symptom.
• Pulmonary disease frequently co-occurred with active disease in other sites, though haemoptysis was the main complaint.

Findings:

• Patients with Behçet's syndrome and haemoptysis showed a male predominance and higher rates of thrombophlebitis and deep vein thrombosis.
• Pulmonary vasculitis, potentially driven by immune complexes, underlies the pathogenesis, leading to thrombosis, infarction, haemorrhage, and aneurysms.
• Corticosteroids and anticoagulants had limited efficacy in severe cases, with pulmonary haemorrhage being a frequent cause of death.

Implications:

• Pulmonary disease with haemoptysis carries a grave prognosis in Behçet's syndrome.
• Accurate diagnosis and timely, appropriate treatment are imperative.
• Pulmonary disease with haemoptysis should be considered a minor diagnostic criterion for Behçet's syndrome.
