Abstract

Abstract: Objective

·To verify the efficacy of adjusted global antiphospholipid syndrome score (aGAPSS) in the risk assessment of new thromboembolic events in the patients with systemic lupus erythematosus (SLE).

Methods

·A total of 330 SLE patients admitted to Renji Hospital, Shanghai Jiao Tong University School of Medicine from December 2012 to March 2016 were retrospectively analyzed. The patients were divided into thrombosis group and control group according to whether there were new thromboembolic events during hospitalization. Demographic data and clinical data of the two groups were collected, and aGAPSS was calculated according to the five risk indicators. Receiver operator characteristic curve (ROC curve) was used to evaluate the diagnostic efficacy of aGAPSS in the patients with new thromboembolic events.

Results

·A total of 60 patients (18.2%) had new thromboembolic events. Compared with the control group, aGAPSS significantly increased in the thrombosis group (P=0.000). The results of ROC curve showed that when the aGAPSS>7 scores, the area under the curve for the diagnosis of new thromboembolic events was 0.752 (95%CI 0.702-0.797), and the sensitivity and specificity were 48.33% and 94.07%, respectively.

Conclusion

·aGAPSS can be used to assess the risk of thromboembolic events in SLE patients and provide reference for clinical treatment decision-making.

Key words: systemic lupus erythematosus (SLE), thromboembolism, adjusted global antiphospholipid syndrome score (aGAPSS)
