WebIntroduction: Dense fine-speckled 70 (DFS70) antibody is defined as an antinuclear antibody (ANA) pattern in indirect immunofluorescence (IIF). The presence of anti-DFS70 antibody has been shown as a potential marker for the exclusion of systemic autoimmune rheumatic diseases (SARD) (without any other SARD-associated autoantibodies). WebAnti-DFS70 antibodies are present in up to 11 % of SRA pa- tients – and in many cases disease-relevant ANA are ob- served at the same time as anti-DFS70. † After a diligent ANA differentiation, either relevant ANA have been determined (fi nding: SRA likely) or not (fi nding: no serological indication of SRA).
WebAnti-DSF70 had a specificity of 86.8%, a sensitivity of 26.9% and a positive predictive value of 68.2% at an ANA titer of ≥1:160, with respect to the absence of a connective tissue disease. Conclusion: Autoantibodies to DSF70 often occur in CTD patients and are therefore not a valid exclusion criteria for a CTD.
