Summary

Antisynthetase syndrome (ASS) is an overlap connective tissue disease characterized by the presence of myositis-specific autoantibodies directed against tRNA-synthetases. Clinical manifestations are myositis, interstitial lung disease (ILD), Raynaud's phenomenon, mechanic's hands and polyarthritis. Clinical presentation varies between ASS patients. ASS is potentially life threatening due to lung involvement, especially in rapidly progressive forms. Anti-histidyl-tRNA synthetase (anti-Jo1) antibodies are the most frequently detected antibodies in ASS (60 % of patients). Anti-threonyl-tRNA synthetase (anti-PL7) and alanyl-tRNA synthetase (anti-PL12) antibodies are each detected in 10 % of patients approximatively. Anti-tRNA-synthetases antibodies are mutually exclusive.

Clinical heterogeneity of ASS patients appears to be associated with specific autoantibodies profile. Patients with anti-Jo1 antibodies have a more systemic presentation (especially with muscle involvement), whereas patients with anti-PL7 or anti-PL12 antibodies have more frequent and isolated ILD. If anti-PL7 and anti-PL12 antibodies are associated with more severe ILD and poorer survival is still matter of debate.

Aims of this study were to compare ILD severity at diagnosis and clinical course in patients with ASS according to antisynthetase autoantibodies types.
