Diffuse Interstitial Lung Disease Revealing Antisynthetase Syndrome

Area of Science:

• Rheumatology and Pulmonology
• Autoimmune Diseases
• Connective Tissue Diseases

Background:

• Interstitial lung disease (ILD) is a common complication of connective tissue diseases, sometimes being the initial presentation.
• Antisynthetase syndrome (ASS) is a complex autoimmune disorder characterized by specific autoantibodies, notably anti-Jo-1.
• The severity of ILD significantly impacts prognosis and guides treatment strategies in ASS.

Observation:

• A 53-year-old female patient presented with ILD.
• The ILD was the presenting symptom that led to the diagnosis of ASS.
• The patient's condition was monitored during follow-up.

Findings:

• The patient was diagnosed with Antisynthetase Syndrome (ASS) based on the presence of ILD.
• Treatment involved high-dose corticosteroids and cyclophosphamide.
• The patient experienced a favorable clinical evolution following treatment.

Implications:

• This case highlights the importance of recognizing ILD as a potential early sign of ASS.
• Aggressive immunosuppressive therapy, including corticosteroids and cyclophosphamide, can effectively manage ASS-associated ILD.
• Prompt diagnosis and management are crucial for improving patient prognosis in ASS.
