目的探讨类风湿关节炎(RA)患者中贫血的发生率、严重程度及其与RA病情活动及治疗间的关系。方法对2002-07-2004-04在北京大学人民医院风湿免疫科住院的239例类风湿关节炎患者进行回顾性分析。结果(1)RA患者中贫血的发生率为51.4%,伴发贫血的程度为轻、中度的贫血;(2)RA贫血组患者和RA不伴发贫血组患者在病程、晨僵、血沉、C反应蛋白、双手X线分级方面的差异有显著性。(3)RA贫血患者和RA不伴发贫血患者在白细胞计数及血小板计数方面差异有显著性。(4)RA贫血患者住院前后的Hb水平存在显著性差异。结论(1)贫血是RA最常见的关节外表现之一,伴发贫血程度为轻、中度贫血。(2)RA伴发的贫血与病情活动性相关,病情活动性越高,贫血程度越重;并且贫血程度越重者,关节破坏越重,病情预后差。(3)RA贫血患者的血红蛋白水平可以随着抗风湿治疗后RA病情的好转而上升。

Anemia in patients with rheumatoid arthritis

Objective To investigate the prevalence of anemia in patients with rheumatoid arthritis (RA) and the relationship between anemia and disease activity of RA. Methods Retrospectively analyze the data of 239 RA patients. Results (1)Estimates of the prevalence of the anemia was 51.4% ;the level of anemia was mild and moderate,and none was severe. (2)There were statistic differences between the patients with anemia and without anemia in disease duration,morning stiff ness,ESR,CRP and degree of X-ray change. (3)There were statistic differences between the patients with anemia and without anemia in leukocyte counts and platelet counts. (4)The level of hemoglobin (Hb) was significantly increased after anti-rheumatoid treatment. Conclusion (1)Anemia is a common sign in individuals with rheumatoid arthritis. The level of anemia is mild and moderate. (2)There are important associations between anemia and disease activity of RA. (3)The level of hemoglobin is increased after anti-rheumatoid treatment.
