摘要
目的探讨关节彩超对不同中医证型的系统性红斑狼疮(SLE)病情活动的评估意义。方法102例不同证型(据诊疗方案分为热毒血瘀型、气血亏虚型、脾肾阳虚型、肝肾阴虚型,为了方便统计,我们将热毒血瘀型记为实证,将后3种证型记为虚证)的SLE患者按有无关节症状分为两组,利用关节彩超观察手、腕、膝、足部关节腔内滑膜炎症、血流信号及骨质破坏程度,根据滑膜分级、多普勒信号和骨侵蚀程度来评估关节炎症并计分。收集所有患者实验室炎性指标和自身抗体结果,并进行病情活动度(SLEDAI)评分,统计分析患者关节彩超评分与实验室炎性指标、关节疼痛数、SLEDAI评分及有无症状的相关性。结果相比于无症状者,患者的关节超声评分和C3含量这两项指标差异有统计学意义(P <0. 05);实证和虚证患者间超声评分差异有统计学意义(P <0. 05),但有或无症状患者间评分差异无统计学意义(P> 0. 05);患者关节疼痛数与超声评分呈显著正相关(B=0. 124,P=0. 003),实验室检测指标中仅C4含量与超声评分呈负相关(B=-4. 018,P=0. 048)。结论关节彩超可作为评估SLE患者证型和病情活动的技术手段之一,尤其对实证(热毒血瘀型)患者具有一定的鉴别意义。
