OBJECTIVE: Neutrophil lymphocyte ratio (NLR) has emerged as a valuable and reliable method for follow-up of systemic inflammatory disease. We herein aimed to evaluate the role of NLR in the clinical follow-up of inflammation and also to compare its relationship with other measures, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). MATERIAL AND METHODS: A total of 35 active ankylosing spondylitis (AS) and 38 healthy volunteers were included in the study. The patient group was enrolled for treatment with one anti-tumor necrosis factor (TNF) drug. Total blood count, ESR, CRP, and BASDAI score were obtained before and 3 months following the treatment. NLR was found with a mathematical calculation of the ratio of neutrophils with lymphocytes. RESULTS: The mean NLR value of the control group and patients was 1.90±0.89 and 2.67±1.17, respectively (p<0.05). After a 3-month course of treatment, the patient group had a mean NLR value of 1.8±0.7, which was significantly lower than pretreatment values (p<0.001). The post-treatment mean ESR, CRP, and BASDAI scores were significantly lower than mean baseline scores (p<0.001, p=0.007, p<0.001, respectively). Also, NLR was found to be correlated with BASDAI, ESR, and CRP (r=0.388, p<0.001; r=0.455, p<0.0001; and r=0.3389, p<0.005, respectively). CONCLUSION: Neutrophil lymphocyte ratio could be a reliable and easily accessible method for follow-up of patients with AS.
