摘要:
目的 探讨实验室常规指标在类风湿关节炎(RA)伴间质性肺疾病(ILD)鉴别诊断中的应用价值。方法 选取2014年1月—2021年10月四川大学华西医院RA-ILD患者80例(RA-ILD组)和单纯RA患者89例(单纯RA组)。收集所有患者的一般资料和实验室常规检测结果[全血细胞计数、抗环瓜氨酸肽(CCP)抗体、类风湿因子(RF)、C反应蛋白(CRP)、红细胞沉降率(ESR)、乳酸脱氢酶(LDH)],并计算淋巴细胞/单核细胞比值(LMR)、中性粒细胞/淋巴细胞比值(NLR)和中性粒细胞/单核细胞比值(NMR)。依据性别、年龄和抗CCP抗体、RF水平将所有患者分别分组。采用Logistic回归分析评估RA-ILD发生的影响因素。采用受试者工作特征(ROC)曲线评价各项指标鉴别诊断RA-ILD的效能。结果 RA-ILD组LDH和MO#均高于单纯RA组(P<0.05),LMR低于单纯RA组(P<0.05);其他指标2个组之间差异均无统计学意义(P>0.05)。LDH和LMR的变化在女性组和年龄<60岁组中更为显著。LDH、MO#升高和LMR降低是RA-ILD发生的危险因素[比值比(OR)值分别为1.01、8.317、0.805,95%可信区间(CI)分别为1.003~1.017、1.555~44.498、0.671~0.966,P<0.05]。LDH、MO#、LMR单项检测和联合检测鉴别诊断RA-ILD的曲线下面积(AUC)分别为0.697、0.611、0.633和0.744;在女性、年龄<60岁或抗CCP抗体<170 U·mL-1的患者中,LDH有较高的鉴别诊断效能(AUC分别为0.777、0.763、0.817)。结论 LDH、MO#升高和LMR降低与RA-ILD发生风险增加有关,尤其是对于女性或年龄<60岁的RA患者。LDH、MO#、LMR或可作为RA-ILD鉴别诊断和风险评估的指标。
