摘要 目的:探讨血清软骨寡聚基质蛋白(COMP)检测在骨关节炎(OA)预后判断中的作用。方法:选取100例资料完整的OA患者与30例正常体检者。检测OA患者血沉(ESR)、C反应蛋白(CRP)及血清中COMP水平,与正常对照组比较。观察分析OA患者基础血清COMP水平与患者年龄、ESR、CRP水平和病程长短的相关性。同时拍摄患者双膝关节X线片,测量膝关节间隙宽度。后每隔1年复查(共5年),考察OA病情进展者(膝关节间隙缩窄≥2mm,或在观察期内行全膝关节置换术)与未进展者ESR、CRP及血清COMP水平的变化与差异,以及血清COMP水平变化与膝关节间隙缩窄的相关性。结果:1OA患者组基础血清COMP检测值为12.4±2.7U/L,正常对照组为5.2±1.8U/L。OA患者组基础血清COMP、ESR及CRP检测值均明显高于正常对照组,差异有显著性。2OA患者组基础血清COMP水平与患者年龄及病程长短无相关性,但与ESR及CRP有相关性。3100例OA患者中有37例OA病情进展,OA病情进展组血清COMP水平明显高于病情未进展组,差异有显著性。血清COMP水平与膝关节间隙缩窄程度相关性分析显示,在OA病情进展组,随着血清COMP水平的增高,关节间隙有明显缩窄的趋势。结论:血清COMP作为关节软骨损伤的标志,对OA的预后判断有一定帮助作用。
