Abstract:
BACKGROUND:The monocyte chemoattactant protein-1 gene polymorphism is associated with spinal tuberculosis susceptibility. OBJECTIVE:To investigate the association between serum monocyte chemoattactant protein-1 expression level and spinal tuberculosis susceptibility in Han population of Hunan province. METHODS:The patients with spinal tuberculosis and the healthy volunteers were recruited in Xiangya Hospital of Central South University from December 2004 to December 2010. The empty peripheral venous blood 2 mL were col ected from the subjects in early morning, then the monocyte chemoattactant protein-1-362 genotypes were detected by polymerase chain reaction and DNA sequencing technology. And the serum monocyte chemoattactant protein-1 level was detected by enzyme linked immunosorbent assay technology. The ROC curve was used for diagnostic tests to calculate diagnostic threshold value of serum monocyte chemoattactant protein-1 level to spinal tuberculosis susceptibility, and to analyze the diagnostic titer. RESULTS AND CONCLUSION:208 patients with spinal tuberculosis and 210 healthy volunteers were included. The serum monocyte chemoattactant protein-1 level of the spinal tuberculosis patients was significantly higher than that of the healthy volunteers [(134.58±51.63) ng/L vs. (39.18±17.45) ng/L, P<0.01]. The serum monocyte chemoattactant protein-1 level could not be affected by gender, but over-expressed in patients with monocyte chemoattactant protein-1-362-CC genotypes. The serum monocyte chemoattactant protein-1 level higher than 101.65 ng/L indicated that the patients might suffered from spinal tuberculosis (sensitivity:85.5%, specificity:94.3%, Youden index:0.799, area under curve of ROC:0.946, 95%confidence interval:0.916-0.975, P<0.01). The serum monocyte chemoattactant protein-1 level may be associated with spinal tuberculosis susceptibility in Han population of Hunan province, highly expressed serum monocyte chemoattactant protein-1 can be used as one of the indicators for the diagnosis of spinal tuberculosis.
