创伤性骨关节炎患者血清SOST、SFRP5水平变化及其对预后的预测价值

Changes of serum SOST and SFRP5 levels in patients with traumatic osteoarthritis and their prognostic value

目的探讨创伤性骨关节炎(PTOA)患者血清骨硬化蛋白(SOST)、分泌型卷曲相关蛋白5(SFRP5)水平变化及其对预后的预测价值。方法选取2020年1月至2022年1月该院收治的84例PTOA患者作为疾病组,另选取同期在该院体检的健康者84例作为健康组。采用酶联免疫吸附试验检测疾病组和健康组血清SOST、SFRP5水平。对疾病组随访1年并采用Lysholm膝关节功能评分评估PTOA患者预后情况。采用Spearman相关性分析法分析PTOA患者血清SOST、SFRP5水平与Lysholm膝关节功能评分的相关性;采用多因素Logistic回归分析PTOA患者预后影响因素;并采用受试者工作特征(ROC)曲线分析血清SOST、SFRP5水平对PTOA患者预后不良的预测价值。结果与健康组比较,疾病组血清SOST、SFRP5水平均明显降低,差异有统计学意义(P<0.05)。Spearman相关性分析结果表明,疾病组血清SOST、SFRP5水平均与Lysholm膝关节功能评分呈正相关。多因素Logistic回归分析结果显示,体重指数>25 kg/m^(2)、入院时凯尔格伦-劳伦斯分级为Ⅲ/Ⅳ级、软骨Outerbridge分级为Ⅲ/Ⅳ级均为PTOA患者预后不良的独立危险因素(P<0.05);术后长期锻炼、SOST、SFRP5水平为保护因素(P<0.05)。ROC曲线分析表明,血清SOST、SFRP5水平联合预测PTOA患者预后不良的ROC曲线下面积(AUC)均高于SOST、SFRP5水平单独预测PTOA患者预后不良的AUC(Z=2.316,P=0.021;Z=2.356,P=0.019)。结论PTOA患者血清SOST、SFRP5水平较健康者降低,二者均与PTOA患者的不良预后相关,对患者预后具有一定的预测效能。

Objective To investigate the changes of serum sclerostin(SOST)and secreted frizzled related protein 5(SFRP5)levels and their prognostic value in patients with post-traumatic osteoarthritis(PTOA).Methods 84 patients with PTOA admitted to the hospital from January 2020 to January 2022 were selected as the disease group,and 84 healthy patients who underwent physical examination in the hospital during the same period were selected as the health group.Serum SOST and SFRP5 levels were detected in the diseased and healthy groups by enzyme-linked immunosorbent assay.The patients in the disease group were followed up for 1 year and the prognosis of PTOA patients was evaluated by Lysholm knee function score.Spearman correlation analysis was used to analyze the correlation between serum SOST,SFRP5 and Lysholm knee function score in PTOA patients.Multivariate Logistic regression was used to analyze the prognostic factors of PTOA patients.The predictive value of serum SOST and SFRP5 levels in poor prognosis of PTOA patients was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the healthy group,the serum SOST and SFRP5 levels in the disease group were significantly decreased,and the difference was statistically significant(P<0.05).Spearman correlation analysis showed that serum SOST and SFRP5 levels were positively correlated with Lysholm knee function score.Multivariate Logistic regression analysis showed that body mass index>25 kg/m^(2),Kelgran-Lawrence gradeⅢ/Ⅳat admission and cartilage Outerbridge gradeⅢ/Ⅳat admission were independent risk factors for poor prognosis in PTOA patients(P<0.05).Long-term exercise,SOST and SFRP5 levels were protective factors(P<0.05).ROC curve analysis showed that the area under ROC curve(AUC)of serum SOST and SFRP5 combined in predicting poor prognosis of PTOA patients was higher than that of SOST and SFRP5 alone in predicting poor prognosis of PTOA patients(Z=2.316,P=0.021;Z=2.356,P=0.019).Conclusion Serum SOST and SFRP5 levels are reduced in PTOA patients compared to healthy individuals,both of which are associated with poor prognosis in PTOA patients and have some predictive efficacy for patient prognosis.
