超声评分在膝关节类风湿关节炎中的临床意义

摘要

目的 探讨膝关节类风湿关节炎超声诊断的价值及超声评分系统的临床意义.方法 收集2013年7月至2015年12月丽水市两家三级甲等综合医院膝关节类风湿关节炎患者500例作为观察组,另收集同期健康成人500例作为对照组.观察两组膝关节滑膜厚度、增生滑膜内血管检出率、超声评分、类风湿性关节炎疾病活动度评分、C反应蛋白、红细胞沉降率、髌上囊积液、髌下囊积液、关节腔积液、膝关节软骨和骨表面情况.结果 与对照组比较,观察组膝关节滑膜厚度[(0.50±0.19)cm vs.(0.13±0.05)cm,P=0.000]、髌上囊液体深度[(0.62±0.27)cm vs.(0.23±0.05)cm,P=0.000]、髌下囊液体深度[(0.58±0.12)cm vs.(0.21±0.04)cm,P=0.000]、关节腔液体深度[(0.48±0.28)cm vs.(0.12±0.08) cm,P=0.000]、红细胞沉降率[(43.29±12.58)mm/h vs.(12.95±4.39)mm/h,P=0.000]、C反应蛋白水平[(8.95±3.29)mg/L vs.(3.29±1.54)mg/L,P=0.000]、增生滑膜内血管检出率(84.20% vs.13.00%,P=0.000)均明显增加.且超声评分与类风湿关节炎患者类风湿关节炎疾病活动度评分、C反应蛋白水平、红细胞沉降率、髌上囊液体深度、髌下囊液体深度和关节腔液体深度均呈正相关(r=0.583、0.258、0.383、0.219、0.228、0.248,均P<0.05).结论 超声在类风湿性关节炎中具有良好的诊断价值,超声评分系统可以较好地反映患者的疾病严重度.%Objective To investigate the diagnostic values of ultrasound in rheumatoid knee arthritis and the clinical significance of ultrasonic scoring system.Methods From July 2013 to December 2015,500 cases of patients with rheumatoid knee arthritis in two grade A class 3 hospitals of Lishui City were collected as the observation group and contemporaneous 500 healthy adults were collected as the control group.The knee joint synovial thickness,vascular detection rate in hyperplasia synovium,ultrasound score,rheumatoid arthritis disease activity score,erythrocyte sedimentation rate (ESR),C reactive protein (CRP),suprapatellar bursa effusion,infrapatellar bursa effusion,joint effusion,knee joint cartilage and bone surface were observed in the two groups.Results Compared with the control group,the observation group got a significant increase in knee joint synovial thickness [(0.50±0.19)cm vs.(0.13±0.05) cm,P=0.000)];depth of suprapatellar bursa fluid [(0.62±0.27)cm vs.(0.23±0.05) cm,P=0.000];depth of infrapatellar bursa fluid [(0.58±0.12)cm vs.(0.21±0.04) cm,P=0.000];joint fluid depth [(0.48±0.28)cm vs.(0.12±0.08) cm,P=0.000];ESR [(43.29±12.58)mm/h vs.(12.95±4.39) mm/h,P=0.000)];CRP level [(8.95±3.29)mg/L vs.(3.29±1.54) mg/L,P=0.000)];vascular detection rate in hyperplasia synovium (84.20% vs.13.00%,P=0.000).Moreover the ultrasound score was positively corrected with rheumatoid arthritis disease activity score,CRP level,ESR,suprapatellar bursa fluid depth,infrapatellar bursa fluid depth and joint fluid depth in the patients with rheumatoid arthritis (r=0.583,0.258,0.383,0.219,0.228,0.248;P<0.05).Conclusion Ultrasound has good diagnostic value in the patients with rheumatoid arthritis,and the ultrasonic scoring system can better reflect the severity of the disease.
