Pulmonary involvement in antisynthetase syndrome

Area of Science:

• Rheumatology
• Pulmonology
• Immunology

Background:

• Lung involvement is a hallmark of antisynthetase syndrome (ASS), significantly impacting patient prognosis.
• Interstitial lung disease (ILD) is the primary pulmonary manifestation, but other conditions like pulmonary arterial hypertension can occur.

Purpose of the Study:

• To review clinical features, radiological patterns, prognostic factors, pathogenesis, and treatment of lung involvement in ASS.
• To highlight clinical differences based on autoantibody specificities in ASS patients.

Main Methods:

• Literature review focusing on lung involvement in antisynthetase syndrome.
• Analysis of clinical data, radiological findings, and treatment outcomes.

Main Results:

• Pulmonary involvement in ASS ranges from mild to rapidly progressive disease, with ILD being most common.
• Autoantibody specificities influence the clinical presentation and prognosis of lung disease in ASS.
• Risk factors for progressive lung damage are critical for identifying patients needing aggressive management.

Conclusions:

• Early diagnosis and appropriate treatment of lung involvement in ASS are essential to prevent chronic lung damage.
• Further research into novel therapeutic options is needed for refractory cases of ASS-related lung disease.
