Anti-CD146 Linked to Silica in Systemic Sclerosis
Comparative analysis across exposed workers, cancer controls, and healthy donors supports specificity.
This study explores the association of anti-CD146 autoantibodies with systemic sclerosis, highlighting their correlation with occupational exposure, particularly to crystalline silica. It examined 93 systemic sclerosis patients, revealing a 15% positivity rate for anti-CD146 antibodies, compared to 5% in healthy controls. Notably, this antibody showcases 57% sensitivity and 88% specificity for indicating occupational exposure. The findings suggest that AACD146 may serve as a significant biomarker in diagnosing and managing systemic sclerosis related to occupational factors, despite limitations in study design.
1. Anti-CD146 autoantibodies may indicate occupational exposure in systemic sclerosis. 2. 15% of systemic sclerosis patients tested positive compared to 5% of healthy controls. 3. Primary exposure linked to crystalline silica. 4. Antibody sensitivity: 57%, specificity: 88%. 5. Findings suggest AACD146 as a promising biomarker in systemic sclerosis management.
