| Popis: | This prospective cohort-designed study was performed to verify whether higher levels of serum lipoprotein(a) (Lp(a)) could be a risk factor for deep vein thrombosis (DVT) in Chinese patients with spinal cord injuries (SCI).During 2013-2014, consecutive patients with first-ever SCI were recruited and assessed for DVT using color Doppler ultrasonography for 15 days after injury and whenever clinically requested. Using logistic regression models, multivariate analyses were performed. Receiver operating characteristic curves tested the overall predicted accuracy of Lp(a) and other markers.In this study, 358 patients were screened in the analysis, and 279 patients with SCI were included and completed the 15-day follow-up. Fifty-five patients (19.7%) were diagnosed with DVT. Patients with SCI with DVT had significantly higher Lp(a) levels on admission (554 mg/L [interquartile range, 416-790 mg/L] vs. 158 mg/L [interquartile range, 72-252 mg/L]; P0.0001). Adjusted for common risk factors, multivariate analyses showed that serum Lp(a) ≥ 300 mg/L could be used independently to predict DVT (odds ratio, 10.35; 95% confidence interval [CI], 2.37-45.35; P0.0001). With an area under the curve (AUC) of 0.91 (95% CI, 0.86-0.94), Lp(a) showed a significantly greater discriminatory ability in predicting DVT compared with high-sensitivity C-reactive protein (AUC, 0.81; 95% CI, 0.74-0.88; P0.01), homocysteine (AUC, 0.78; 95% CI, 0.71-0.84; P0.01) and age (AUC, 0.66; 95% CI, 0.59-0.73; P0.001).Increased serum Lp(a) levels were independent predictors of DVT in patients with SCI in China, suggesting a possible role of Lp(a) in the pathogenesis of DVT. |
