摘 要 目的:探讨免疫球蛋白G型类风湿因子(IgG-RF)在类风湿关节炎患者中的检测价值,为临床此类患者的诊断和治療提供依据。方法:选取498例类风湿关节炎患者,根据其IgG-RF水平分为阳性组(n=204)和阴性组(n=294)并分析IgG-RF与类风湿关节炎患者临床表现、各实验室指标、以及病情活动程度的相关性。结果:IgG-RF阳性组患者骨侵蚀、关节畸形、红细胞沉降率升高和高IgG血症的发生比例及吸烟指数、吸烟史和现吸烟比例均较阴性组高(P<0.05);两组患者在DAS28评分、关节外表现发生情况、低补体血症、血小板升高、链球菌溶血素O阳性以及C-反应蛋白升高等方面的发生情况差异无统计学意义(P>0.05);结论:IgG-RF水平在类风湿关节炎患者中的检测价值显著,可在临床上进一步试验。

ABSTRACT Objective: To explore the value of the detection of immunoglobulin G-type rheumatoid factor (IgG-RF) in patients with rheumatoid arthritis so as to provide reference for the diagnosis and treatment of these diseases. Methods: A total of 498 patients with rheumatoid arthritis were selected and divided into a positive group (n=204) and a negative group (n=294) based on the IgG-RF positive determination threshold. The correlation between IgG-RF levels and clinical manifestations, laboratory indicators, and disease activity were analyzed. Results: The incidence of bone erosion and joint deformity, erythrocyte sedimentation rate increment, hyperglycemia, smoking index and history and current smoking rate were higher in the positive group than the negative group (P<0.05). There were no significant differences in the incidence of extra-articular manifestations, hypocomplementemia, platelet elevation, streptolysin O positive and C-reactive protein elevation and the DAS28 scores between the two groups (P>0.05). Conclusion: IgG-RF level has a significant detection value in patients with rheumatoid arthritis and can be further tried in clinical practice.

类风湿关节炎是临床常见的自身免疫性疾病,是一种慢性综合征,女性发病率远高于男性,且多发于40~60岁年龄段[1]。该病主要表现为患者出现持续性、对称性关节疼痛和肿胀,晨起受累关节僵硬,中晚期患者发生关节畸形,以掌指关节屈曲及尺度偏斜最为常见,此外,部分患者会出现皮下结节及发热症状[2-3]。类风湿关节炎患者长期遭受该疾病带来的身体疼痛及心理负担,生活质量严重下降。由此可见,早期有效的诊断对此类患者的治疗及预后具有重要意义[4-5]。类风湿因子(RF)一直作为类风湿关节炎的诊断指标沿用至今,最常用的是免疫球蛋白M型RF(IgM-RF),但由于其灵敏度高、特异度较差,偶尔有患者漏诊。近年来,有研究表明,免疫球蛋白G型RF(IgG-RF)对类风湿关节炎的检测也具有显著效果[6-7]。……
