Subclinical atherosclerosis may be seen at an early age of ankylosing spondylitis (AS). Syndecan 1 (S1) expression is increased in response to proinflammatory cytokine and inflammation. High S1 may reduce carotid atherosclerosis progression. We aimed to investigate the relationship between S1 levels and subclinical atherosclerosis in patients with AS. Fifty-eight patients diagnosed with AS and 58 age-, sex-, and body mass index-matched controls were included in the study. S1 level and carotid intima-media thickness (cIMT) were evaluated using appropriate methods. AS patients' cIMT (0.53 ± 0.1 vs 0.45 ± 0.1 mm, p = .008), S1 (6.0 [1.7-149.2] vs 5.5 [1.0-29.8] ng/ml, p = .020), CRP (C-reactive protein) (2.1 [0.1-19.7] vs 1.1 [0.3-9.6] mg/dl, p = .012), fibrinogen (330.2 ± 87.0 vs 278.0 ± 54.5 mg/dl, p < .001) values were significantly higher than the values of the control group. There was a negative correlation between cIMT and CRP (p = .034), age (p < .001), disease duration (p = .005), BASDAI (p = .048) and fibrinogen (p = .009) in AS patients. There was a negative correlation between cIMT and S1 (p = .029). In multivariate analysis, an independent relationship was found between cIMT and age (β = 0.611, p < .001) and syndecan (β = -0.196, p = .046). S1 level may rise in AS patients to suppress the inverse effects of proinflammatory cytokines and inflammation. A negative relationship between the cIMT values of AS patients and S1 level may reveal that S1 has a protective effect on the development of atherosclerosis in AS patients, independent of disease activity.
