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.
