Brief Summary
Axial spondyloarthritis is an inflammatory disease characterized by the involvement of the sacroiliac joints and the spine. Disease activity and structural changes are determined by using physical examination, imaging studies, laboratory parameters, and patient-reported indices. Among laboratory studies, Erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) are the most commonly utilized parameters. However, the level of ESR and CRP are inadequate in demonstrating disease activity and inflammation compared to other diseases. In this study, the investigators aimed to analyze and compare the systemic inflammatory index (SII), which is a hematologic parameter between subjects with radiographic axial spondyloarthritis, non-radiographic axial spondyloarthritis, and healthy controls. Secondarily, the relationship between disease activity and enthesitis score and SII scores in patients with radiographic and non-radiographic axial spondyloarthritis will be investigated.

Bath Ankylosing Spondylitis Disease Activity Index includes six questions which includes the following six parameters: fatigue, spinal pain, peripheral joint pain, attachment point inflammation, and duration and severity of morning stiffness. A total score, ranging from 0 to 10, was calculated according to the patients' responses to six questions, with a higher score indicating more severe illness.
The ASDAS-ESR is deduced using formula that is chosen by the ASAS group. ASDAS-ESR is calculated with the answers of spinal, peripheral pain, morning stiffness on BASDAI, the patient global assessment, and erythrocyte sedimentation rate (mm/h).
The ASDAS-CRP is deduced using formula that is chosen by the ASAS group. ASDAS-CRP is calculated with the answers of spinal, peripheral pain, morning stiffness on BASDAI, the patient global assessment, and erythrocyte C-reactive protein (mg/dl).
It is used to evaluate the sensitivity of enthesis points by palpation in patients with ankylosing spondylitis. Scoring is done by giving 1 point for sensitive areas and 0 points if there is no sensitivity on the fifth lumbar spinous process, bilateral first and seventh costochondral joints, iliac crystals, posterior and anterior iliac spines, attachment sites of achilles tendon to the calcaneus.
