Kashin-Beck disease(KBD) is an endemic degenerative osteoarthropathy of uncertain etiology. The aim of our study was to identify changes in C-telopeptide of type Ⅱ collagen(CTX-Ⅱ), pyridinoline(PYD), and deoxypyridinoline(DPD) among KBD patients. 54 KBD patients and 78 healthy controls were included this study. Urinary samples were collected and measured by ELISA. The median quantities of PYD, CTX-Ⅱ, and DPD of KBD patients were 1107.73 ng/μmol.cre, 695.11 ng/μmol.cre, and 1342.34 pml/μmol.cre, while the median quantities of healthy controls were 805.59 ng/μmol.cre, 546.47 ng/μmol.cre, and 718.15 pml/μmol.cre, respectively. The differences between KBD patients and healthy controls were statistically significant(Z = 4.405, 3.653, and 3.724; P < 0.001). The higher levels of PYD, CTX-Ⅱ, and DPD detected in KBD patients indicate that they could be used as biomarkers of KBD.
