Serum salusin-β levels in patients with systemic lupus erythematosus
CLINICAL RHEUMATOLOGY(2023)
摘要
Objective Endothelial dysfunction (ED) has an important role in the pathogenesis of systemic lupus erythematosus (SLE). Studies on other inflammatory diseases show that salusin-β with various mechanisms may play a role in the promotion of ED and inflammation. The aim of this study was to measure serum salusin-β levels in SLE patients and evaluate it as a potential biomarker in assessing SLE activity and predicting organ involvement. Methods In a cross-sectional study, 60 patients diagnosed with SLE and 30 age- and sex-matched healthy controls were enrolled. Disease activity of SLE patients was assessed by the systemic lupus erythematosus disease activity index 2000 (SLEDAI-2 K). Serum levels of salusin-ß were measured using a human salusin-ß enzyme-linked immunosorbent assay kit. Results Serum salusin-β levels in SLE and control groups were 474.2 ± 117.1 pg/ml and 157.7 ± 88.7 pg/ml, respectively. The difference was significant ( P = 0.001). There was no significant correlation between serum salusin-β levels with age ( r = − 0.06, P = 0.632) and SLEDAI ( r = − 0.185, P = 0.158). In patients with nephritis and thrombosis, serum salusin-β was significantly higher. In addition, in patients with serositis, serum salusin-β was significantly lower. Multiple linear regression analysis showed that serum salusin-β levels retained a significant association with nephritis and thrombosis after model adjustment for serositis, nephritis, and thrombosis. Conclusions Our findings showed that salusin-β might have a possible role in the pathogenesis of SLE. Salusin-β may be a potential biomarker for nephritis and thrombosis in SLE. Key Points • Serum salusin-β levels were significantly higher in SLE patients than the control group. • There was no significant correlation between serum salusin-β levels with age and SLEDAI. • Serum salusin-β levels retained a significant association with nephritis and thrombosis.
