May The Neutrophil Lymphocyte Ratio be A New Marker For Uveitis Development In Ankylosing Spondylitis?

Abstract

May The Neutrophyl Lymphocıde Ratıo Be A New Marker For Uveıt Development In Ankylosıng Spondilitis? Introduction Neutrophil-lymphocyte ratio (NLR) is a marker that has been researched in recent years to be used as a marker of inflammation. The aim of our study is to evaluate the NLR in Ankylosing Spondylitis (AS) patients with uveitis, which is an extraarticular involvement, while having uveitis and to compare it with the NLR at first admission. Methods: Ninety patients with uveitis and diagnosed with AS according to the modified New York Criteria were included in the study. The files of the patients were analyzed retrospectively. NLR was calculated arithmetically using neutrophil and lymphocyte values in complete blood count. Results: There was no significant difference between the genders in terms of age, duration of diagnosis, and body mass index (p = 0.104, p = 0.073, p = 0.557, respectively). No significant difference was found between genders in terms of NLR values at first admission and at the time of uveitis (p = 0.016). The aim of our study was that there was a significant difference between the NLR values (1.660 ± 0.67 and 2.623 ± 1.293, respectively) in both genders at first admission and at the time of uveitis (p <0.001). The aim of our study was that there was a significant difference between the NLR values (1.660 ± 0.67 and 2.623 ± 1.293, respectively) in both genders at first application and at the time of uveitis (p <0.001). Conclusion: As a result, we found that NLR increased when having uveitis compared to the time of first admission. NLR may be a new marker for evaluating increased inflammation and disease activity in AS patients. Keywords: Ankylosing spondylitis, disease activity, neutrophil lymphocyte ratio, uveitis
