摘要: 目的 探讨类风湿性关节炎(rheumatoid arthritis,RA)患者抗环瓜氨酸肽(anti-cyclic citrullinated peptide,ACCP)抗体与超声检出的骨侵蚀的相关性。方法 对符合1987年RA分类标准的RA患者的双侧腕关节、第1~5掌指关节及第2~3近节指间关节进行常规灰阶超声和能量多普勒(power Doppler,PD)超声检查,观察关节骨侵蚀、滑膜增厚及PD血流信号情况,分析ACCP抗体阳性和阴性患者的骨侵蚀、滑膜增厚、PD血流信号评分之间的差异,并探讨ACCP、病程与骨侵蚀的关系。结果 RA患者101例,其中女性81例,ACCP抗体阳性患者75例,ACCP抗体阳性组与阴性组的骨侵蚀总评分在两组间差异有统计学意义(P=0.009),而滑膜增厚及PD血流信号总评分在两组间差异无统计学意义。在病程>3年的患者中,ACCP抗体阳性组与阴性组之间的骨侵蚀总评分差异有统计学意义(P=0.01)。结论 ACCP抗体阳性、病程>3年的RA患者有较高的骨侵蚀评分。

Abstract: Objective To explore the relationship between the anti-cyclic citrullinated peptide (ACCP) antibody and bone erosion in patients with rheumatoid arthritis (RA). Methods One hundred and one RA patients were enrolled. Eighty-one of these patients were female, and 75 cases were ACCP positive. Gray scale (GS) and power Doppler (PD) ultrasound was performed to assess bone erosion, synovial hypertrophy, and PD signal. The bilateral wrists, I-V metacarpophalangeal joints, Ⅱ-Ⅲ metacarpophalangeal joints of the hands were detected by GS and PD ultrasound. Appropriate statistical analysis methods were used to analyze the difference of ultrasonographic characteristics in ACCP-positive and ACCP-negative patients, and explore the relationship of the ACCP antibody, disease duration with bone erosion. Results Bone erosion score in ACCP-positive patients was significantly greater than in ACCP-negative patients (P=0.009). No statistically significant difference was observed in synovial hypertrophy and PD signal between ACCP-positive patients and ACCP-negative patients. In RA patients with a disease duration >3 years, however, bone erosion score in ACCP-positive patients was significantly greater than that in ACCP-negative patients (P=0.01). Conclusion ACCP-positive RA patients with a disease duration >3 years had higher bone erosion score.
