Background/Purpose: Vaspin is a novel adipokine with insulin-sensitizing functions that exerts anti-inflammatory actions1,2. It has been associated with cardiovascular (CV) disease, CV risk factors and inflammation in the general population and in chronic inflammatory conditions different from axial SpA (axSpA)2-4. In particular, it has been suggested that vaspin may act as a compensatory mechanism for inflammation and CV disease1,3. This could be relevant for axSpA, given the high incidence of CV disease (mainly due to accelerated atherosclerosis) exhibited by these patients5,6, which turns this comorbidity into a matter of major concern among rheumatologists. However, data on the role of vaspin regarding surrogate markers of atherosclerosis in the context of axSpA is scarce. For this reason, we aimed to evaluate the implication of vaspin in subclinical atherosclerosis in axSpA at the genetic and protein level.
Methods: This study included 385 patients that fulfilled the Assessment of SpondyloArthritis international Society (ASAS) classification criteria for axSpA7. Clinical data was retrieved from medical records. Carotid US was performed to evaluate the presence of subclinical atherosclerosis (carotid plaques and abnormal carotid intima-media thickness [cIMT] values). 3 polymorphisms of vaspin (rs2236242, rs35262691 and rs7159023), previously associated with CV risk factors and/or reported as functional gene variants, were genotyped by TaqMan probes. Serum vaspin levels were assessed by ELISA. Statistical analysis was performed using STATA® v. 11.1, adjusting the results by potential confounding factors.
Results: We disclosed that the C allele of rs35262691 conferred a higher risk of developing carotid plaques in axSpA (p< 0.05)(Table 1). Regarding serum vaspin levels, even if they showed no statistically significant association with carotid plaques or cIMT values, these values positively correlated with factors associated with high CV risk such as systolic blood pressure (p=0.02) and waist circumference (p=0.03). Furthermore, serum vaspin levels were significantly higher in female patients than in males (p< 0.001).
Conclusion: Our results show for the first time that vaspin rs35262691 polymorphism is associated with carotid plaques in axSpA. The relevance of this molecule in the atherosclerotic process is further demonstrated by the relationship between serum levels and CV risk factors. All these data support a key role of vaspin in atherosclerosis in axSpA.
