Clinical diagnosis of patients and demographic characteristics were obtained from the patients’ medical records. </p> <p style="text-align:justify;"> <b>Results: </b> A total of 337 subjects (305 women, 32 men) were included in this study. The mean age was 49.8 ± 14.2 years. Of the 337 participants, 111 (32.9%) had an IIF-DFS pattern and 226 (67.1%) had a non-DFS pattern. Anti-DFS70 antibodies were positive in 20.1% of individuals. Sixty eight individuals had AARDs. An IIF-DFS pattern was observed in 22.1% and a non-DFS pattern was observed in 77.9% of individuals with AARDs (p <0.05). Anti-DFS70 antibodies were positive in 13.2% of patients with AARDs. The frequency of AARDs was significantly lower in individuals with anti-DFS70 antibodies compared to individuals with other anti-ENAs antibodies (p <0.05). </p> <p style="text-align:justify;"> <b>Conclusion: </b> Anti-DFS70 antibodies may be present in patients with AARDs but AARDs are less prevalent in patients who had anti-DFS70 antibodies, compared with patients who had other anti-ENAs. <br /> </p>}, number={3}, publisher={Alanya Alaaddin Keykubat Üniversitesi}
