[摘要] 目的 探討类风湿性关节炎(RA)患者血清25-羟基维生素D3[25(OH)D3]水平的变化,并分析其与CRP、RF、RDW的关系。 方法 选取2018年1月至2019年7月100例于我院就诊并诊断为类风湿性关节炎的患者(RA组)及100例健康体检人群(对照组)进行研究;根据疾病活动指数将RA组分为低活动组(n=57)和高活动组(n=43),比较各组25(OH)D3、CRP、RF、RDW水平,同时对25(OH)D3与CRP、RF、RDW的相关性进行Pearson相关分析。 结果 与正常对照组比较,RA组25(OH)D3水平明显降低(P<0.05);CRP、RF、RDW水平明显升高(P<0.05)。高活动组25(OH)D3水平明显低于低活动组(P<0.05),而CRP、RF、RDW明显高于低活动组(P<0.05)。Pearson相关分析显示,25(OH)D3与CRP、RF、RDW呈负相关(r值分别为-0.380、-0.433、-0.220,P<0.05)。 结论 25(OH)D3水平可能与RA的发生发展及严重程度有一定关系,RA患者25(OH)D3水平的检测与对病情及治疗效果的判断具有重要价值。

[Abstract] Objective To explore the changes of serum 25-hydroxyvitamin D3 [25(OH)D3] in patients with rheumatoid arthritis (RA), and to analyze its correlation with CRP, RF and RDW. Methods A total of 100 patients admitted to our hospital and diagnosed as RA (the RA group, n=100) and 100 examined healthy people (the control group, n=100) from January 2018 to July 2019 were researched. According to disease activity index, the RA group was divided into the low activity group(n=57) and the high activity group(n=43). The levels of 25(OH)D3, CRP, RF and RDW in each group were compared, and Pearson correlation analysis was made on the correlation between 25(OH)D3 and CRP, RF and RDW at the same time. Results Compared with the normal control group, the level of 25(OH)D3 in the RA group decreased significantly(P<0.05). The levels of CRP, RF and RDW increased significantly(P<0.05). The level of 25(OH)D3 in the high activity group was significantly lower than that in the low activity group(P<0.05), while CRP, RF and RDW were significantly higher than those in the low activity group(P<0.05). Pearson correlation analysis showed that 25(OH)D3 was negatively correlated with CRP, RF and RDW(r=-0.380, -0.433, -0.220 respectively(P<0.05). Conclusion The level of 25(OH)D3 can be related to the occurrence, development and severity of RA, and the detection of 25(OH)D3 level in patients with RA is of great value in judging the condition and therapeutic efficacy.

类风湿关节炎(Rheumatoid arthritis,RA)是一种侵犯关节为主的关节滑膜炎特征的全身性、多系统受累的炎症性自身免疫性疾病。持续的双手和腕关节及全身小关节滑膜的慢性炎症、血管翳形成是患者致畸和致残的主要病因之一[1]。目前发病机制尚不明了,免疫系统功能紊乱,淋巴细胞数目和功能的异常为主要观点,遗传和环境因素、炎症反应可能对RA的发生、发展具有一定的促进作用。最新研究发现,维生素D[25-hydroxyvitamin D3,25(OH)D3]可作为一种新型的免疫调节剂,可以调节机体免疫平衡、抑制炎症反应[2]。近年来外周血细胞参数水平作为一些自身免疫性疾病和肿瘤的新型炎症标志物也被广泛研究,如中性粒细胞-淋巴细胞比值(Neutrophil/lymphocyte ratio,NLR)、红细胞分布宽度(Erythrocyte distribution width,RDW)等[3]。然而,关于RA患者25(OH)D3水平的研究结果尚不一致,且25(OH)D3水平变化与C反应蛋白(C-reactive protein,CRP),类风湿因子(Rheumatoid factor,RF)以及血细胞参数RDW水平之间的关系亦不明确,本文旨在探讨类风湿性关节炎患者血清中25(OH)D3、CRP、RF、RDW水平及之间的相关性,为临床诊断与治疗提供依据,现报道如下。……
