Title: Neutrophil-to-lymphocyte ratio in thyroid ophthalmopathy
Abstract: PURPOSE: To evaluate the neutrophil-to-lymphocyte ratio (NLR) levels to predict the severity of infl ammation in thyroid ophthalmopathy (TO).METHODS: Fifty-six patients with TO and 40 healthy subjects were included in this study.TO patients were divided into two groups according to clinical activity score (CAS).Group 1 included 24 active TO patients and Group 2 included 32 inactive TO patients.The thyroid status, white blood cell (WBC), neutrophil, and lymphocyte counts were performed.NLR was calculated by dividing the neutrophil count by the lymphocyte count.RESULTS: The mean age was 53.6 ± 5.4 in active TO group, 54.2 ± 5.6 in inactive TO group, and 52.7 ± 5.2 in the control group.The WBC, neutrophil, lymphocyte and NLR levels were higher in patients with TO than in the control group (p < 0.05).A signifi cant difference in NLR was found between the inactive and active TO groups (p < 0.05).CONCLUSION: NLR values were found to be higher in patients with TO than in controls.NLRvalues were also found higher in active TO patients than in inactive TO patients (Tab.3, Ref. 26).
