ABSTRACT
BACKGROUND: Recently, the rise of syphilitic seroresistance brings great confusion to the clinical diagnosis and treatment of syphilis, and no clear diagnostic marker has been found to distinguish syphilitic seroresistance from other progression of syphilis. This study evaluated the serum chemokines levels of CCL2, CXCL8, CXCL9, and CXCL10 and its correlation with blood routine, coagulation, and biochemical indexes in seroresistant syphilitic patients.
METHOD: Serum levels of chemokines were quantitatively determined by Flow Cytometric Bead Array (CBA). The results expressed in pg/ml. Clinical parameters were detected and analyzed according to the clinical laboratory standards. A correlation analysis was subsequently performed.
RESULTS: The seroresistant syphilitic patients increased significantly serum chemokines levels of CXCL8 (***p < 0.001), CXCL9 (***p < 0.001), and CXCL10 (**p < 0.01) when compared to noninfected individuals, but the CCL2 was not statistically significant, and serum CXCL8 shows a strong association with platelets (r = 0.51, **p = 0.004) and serum CXCL10 was significantly positively related to INR levels (r = 0.49, **p = 0.007).
CONCLUSION: Increasing serum abnormalities in CXCL8, CXCL9, and CXCL10 level combining with platelets of peripheral blood and plasmatic INR in syphilis patients may be helpful for the diagnosis of serofast state.
