Summary
Patients with primary Sjögren
Area of Science:
- Rheumatology and Immunology
Background:
- Primary Sjögren's syndrome is a chronic autoimmune disease affecting exocrine glands.
- Autoantibody status (ANA/anti-ENA) is a key factor in autoimmune disease classification.
Purpose of the Study:
- To investigate the clinical differences in primary Sjögren's syndrome based on the presence or absence of antinuclear and anti-ENA antibodies.
Main Methods:
- Fifty female patients diagnosed with primary Sjögren's syndrome were divided into two groups: ANA/anti-ENA positive and ANA/anti-ENA negative.
- Evaluation included glandular and extraglandular involvement, and corticosteroid treatment frequency.
Main Results:
- ANA/anti-ENA negative patients exhibited milder and delayed onset of both glandular and extraglandular disease.
- Less frequent corticosteroid use was observed in ANA/anti-ENA negative patients.
- Leukopenia was exclusively observed in ANA/anti-ENA positive patients.
Conclusions:
- Autoantibody status significantly influences the clinical presentation and disease severity in primary Sjögren's syndrome.
- ANA/anti-ENA negativity may indicate a less aggressive disease course.
