系统性红斑狼疮患者活动性发热特点及相关性分析

目的 探讨系统性红斑狼疮(SLE)患者活动性发热的临床特点并进行相关性分析.方法 由各参研单位根据统一方式收集病历资料,总结江苏省1999-2009年住院SLE患者的临床资料及治疗情况,分析发热与SLE的临床表现、免疫学指标、疾病活动及治疗情况间的关系.组间的计数资料比较采用x2检验,非正态分布的计量资料比较采用秩和检验,相关性分析采用Logistic回归分析.结果 1762例SLE患者纳入研究范围,其中活动性发热患者729例,非发热患者1033例,通过对照研究,发热组入院年龄、是否初治、光敏感、浆膜炎、神经精神系统累及、肝脾淋巴结肿大、血白细胞、血红蛋白、红细胞沉降率(ESR)、C反应蛋白(CRP)、丙氨酸转氨酶(ALT)、白蛋白、血清肌酐、补体C3、抗双链DNA (dsDNA)抗体、抗Sm抗体、SLE疾病活动指数(SLEDAI)评分、既往治疗与非发热组比较差异有统计学意义(尸＜0.05)；Logistic回归分析显示血白细胞异常[比值比(OR)=1.396,95％可信区间(CI)1.114～1.711,P=0.004]、CRP (OR=1.005,95％CI 1.002～1.009,P=0.002)、ALT( OR=1.003,95％CI 1.001 ～1.005,P=0.005)、血清肌酐(OR=0.997,95％CI 0.995～0.999,P=0.007)、血红蛋白(OR=0.986,95％CI0.981～0.992,P=0.000)、入院年龄(OR=0.984,95％CI 0.974～0.993,P=0.001)及环磷酰胺应用比例(OR=0.557,95％CI 0.382～0.813,P=0.002)与SLE 患者发热相关.结论 发热是SLE常见的临床表现之一.血白细胞下降、CRP升高、肝功能异常、贫血、入院年龄轻为SLE患者出现发热症状的危险因素,而肾累及、环磷酰胺应用为保护因素.

Clinical features and correlation research of fever in systemic lupus erythematosus patients

Objective To investigate the clinical features of systemic lupus erythematosus (SLE) patients with fever and find out the related factors.Methods Data was collected by the same methods in the past ten years in fifteen hospitals in Jiangsu province and then the data were retrospectively analyzed.The potentially possible risk factors of fever in SLE were selected and then analyzed by chi-square test,Wilcoxon rank sum test and Logistic regression analysis.Results All 1762 patients were investigated.Seven hundred and twenty-nine had active fever.Age at hospitalization,initially treated patients,photosensitivity,serositis,nervous system involvement,generalized lymphadenopathy/hepatosplenomegaly,white blood cell count (WBC),haemoglobin (HB),erythrocyte sedimentation rate (ESR),C-reaction protein (CRP),alanine aminotransferase (ALT),albumin (ALB),serum creatinine (Scr),complement C3,anti-dsDNA antibodies positive rate,anti-Sm antibodies positive rate,SLEDAI score and past therapies were factors associated with SLE fever.Logistic regression analysis showed that abnormal WBC count (OR=1.396,95％CI 1.114-1.711,P=0.004),CRP(OR=1.005,95％CI 1.002-1.009,P=0.002),ALT(OR=1.003,95％CI 1.001-1.005,P=0.005),Scr (OR=0.997,95％CI0.995-0.999,P=0.007),HB (OR=0.986,95％CI 0.981-0.992,P=0.000),age (OR =0.984,95％ CI 0.974-0.993,P=0.001 ) and past usage of cyclophosphamide (CTX) (OR =0.557,95％CI 0.382-0.813,P=0.002) were correlated with SLE fever.Conclusion Fever is one of the most common clinical manifestations of SLE patients.Leucopenia,elevated CRP levels,liver function abnormalities,anemia,younger age are risk factors for SLE fever,while renal impairment and past usage of CTX are protective factors.
