摘要
目的探讨川崎病(KD)患儿血清五聚蛋白-3(PTX 3)水平对静脉注射免疫球蛋白(IVIG)抵抗的影响和预测价值。方法选择2017年1月—2022年7月诊治的KD患儿为研究对象,根据IVIG治疗情况判断是否存在IVIG抵抗,应用非条件二分类logistic回归分析PTX3与IVIG抵抗的关系,应用受试者工作特征(ROC)曲线分析PTX 3预测IVIG抵抗的效能。结果纳入292例KD患儿,男187例、女105例,中位年龄25.0(10.0~32.0)月,出现IVIG抵抗49例(16.8%)。非条件二分类logistic回归分析显示,皮疹、颈淋巴结肿大、白细胞计数及CRP升高、血清钠下降、ALT≥33.2 IU/L、肌酐≥42.5μmol/L、血清铁蛋白≥180.3μg/L、PTX3≥19.3 ng/mL为影响IVIG抵抗的危险因素(P<0.05)。ROC曲线显示,PTX3预测IVIG抵抗的曲线下面积(AUC)为0.77(95%CI:0.68~0.85,P<0.001),具有中等准确度。取截断值21.5 ng/mL时,预测IVIG抵抗的灵敏度为0.71,特异度为0.69,约登指数为0.40。结论PTX 3是影响KD患儿IVIG抵抗的独立危险因素,在预测IVIG抵抗方面具有较好效能。
Objective To explore the effect and predictive value of serum pentraxin-3(PTX 3)level on intravenous immunoglobulin(IVIG)resistance in children with Kawasaki disease(KD).Methods Children with KD diagnosed and treated from January 2017 to July 2022 were selected as the study objects.IVIG resistance was determined according to the IVIG treatment outcome.The relationship between PTX 3 and IVIG resistance was analyzed by binary logistic regression.Receiver operating characteristic(ROC)curve was used to analyze the efficacy of PTX 3 in predicting IVIG resistance.Results A total of 292 KD children(187 boys and 105 girls)with a median age of 25.0(10.0-32.0)months were included,and 49 patients(16.8%)showed IVIG resistance.Binary logistic regression analysis showed that the independent risk factors of IVIG resistance were rash,cervical lymph node swelling,increased white blood cell count and CRP,decreased serum sodium,ALT≥33.2 IU/L,creatinine≥42.5μmol/L,serum ferritin≥180.3μg/L and PTX 3≥19.3 ng/mL.The ROC curve showed that the area under the curve(AUC)of PTX 3 for predicting IVIG resistance was 0.77(95%CI:0.68~0.85,P<0.001),with moderate accuracy.When the cut-off value was 21.5 ng/mL,the sensitivity,specificity,and Youden index for predicting IVIG resistance were 0.71,0.69,and 0.40 respectively.Conclusions PTX3 is an independent risk factor for IVIG resistance in KD children,and has a good effect in predicting IVIG esistance.
