Outline of Final Research Achievements |
Biomarkers for knee osteoarthritis are quite important in estimating onset and progression of OA. To investigate the relationship between radiological knee OA changes and values of urinary CTX-II, one of candidate biomarkers of knee OA, in Japanese, we performed longitudinal population-based cohort study for three years. Urinary CTX-II was significantly higher in the OA progression group than that in the OA non-progression group in female. We further performed X-ray evaluation of knee OA at six years and found that uCTX-II values became significantly higher at three years than those at the start point in OA onset group of both gender. In addition, cases with higher values of mean uCTX-II had higher numbers of knee OA progression cases in both gender. These findings suggest that repeated measurements of uCTX-II could estimate the onset and progression of knee OA in Japanese.
