Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aimed to investigate the relationship between the systemic immune inflammation index (SII), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and disease activity and functional status in patients with ankylosing spondylitis (AS). A cross-sectional clinical study was conducted, and a total of 90 patients diagnosed with AS according to the Modified New York Criteria, aged between 18 and 65, who presented to our outpatient clinics were included in the study. Demographic data, disease duration, age at symptom onset, and laboratory parameters, including platelet, neutrophil, basophil, eosinophil, lymphocyte counts, mean platelet volume (MPV), red blood cell distribution width (RDW), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), were recorded. NLR and PLR values were calculated. The Systemic Immune Inflammation Index (SII) was calculated by dividing the product of neutrophil and platelet counts by the lymphocyte count. We investigated all of these parameters and disease activity scores. Disease activity was assessed with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), spinal mobility with the Bath Ankylosing Spondylitis Metrology Index (BASMI), and functional status with the Bath Ankylosing Spondylitis Functional Index (BASFI). In addition, during the routine follow-ups of patients, requested blood tests were examined, and platelet, neutrophil, basophil, eosinophil, lymphocyte counts, mean platelet volume (MPV), RDW (red blood distribution width), CRP, and ESR values will be recorded. Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune inflammation index (SII) were calculated
