摘要:

目的  评估血清骨保护素(OPG)在预测川崎病(KD)合并冠状动脉损害(CAL)中的应用价值。方法  选择90例KD患儿作为KD组、30例因感染性疾病发热的患儿为发热组、20例系统性红斑狼疮(SLE)患儿为SLE组、30例健康儿童为正常对照组。对所有研究对象均应用ELISA法检测血清骨保护素(OPG),并同时检测外周血象、肝功、血沉(ESR)、C反应蛋白(CRP)等生化指标。90例KD患儿均行经胸二维超声心动图(TTE)检查,对合并CAL者进一步根据其冠状动脉扩张程度(冠状动脉瘤直径)进行CAL严重程度的分组,应用Logistic逐步回归分析等统计学方法筛选出KD并CAL的危险因素,并进一步应用ROC分析评价相关危险因素在预测CAL方面的价值。结果  KD组患儿血清OPG含量明显高于发热组、SLE组及正常对照组(P<0.05)。90例KD患儿中有38例(42.2%)在急性期合并了CAL,其中冠脉扩张者18例,冠脉瘤14例,巨大冠脉瘤6例。统计结果显示,KD合并CAL组血清OPG、CRP明显高于KD无CAL患儿组(P<0.05),KD合并CAL组血ALB水平低于KD无CAL组(P<0.05)。Logistic逐步回归分析表明,OPG、CRP及ALB是KD发生CAL的危险因素。ROC分析表明,OPG、CRP及ALB是预测KD急性期发生CAL的可靠指标。线性回归分析表明,OPG与CAL的严重程度呈正相关(r=0.895)。结论  OPG是KD患儿发生CAL的危险因素,并与CAL的严重程度密切相关,可以用于预测急性期KD患儿是否发生CAL。

Abstract:

Objective  To evaluate the clinical value of osteoprotegerin(OPG) in predicting coronary artery lesions(CAL) of Kawasaki disease(KD). Methods   90KD patients(KD group), 30 febrile patients with infective diseases( fever group), 20 patients with sytemic lupus erythematousus(SLE group) and 30 healthy children(control group) were included in this study.  Blood samples were collected for routine laboratory tests, including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell count(WBC), hemoglobin(HB), platelet count (PLT), serum albumin(ALB) and OPG concentration. The severity of coronary arterylesions was determined by the diameter of the involved coronary artery. Multivariate logistic regression was used to find risk factors of CAL. A receiver operatingcharacteristic curve (ROC) was established to confirm the diagnostic value of the risk factors.  Results  Serum OPG level of the KD group is higher than that in the fever group, SLE group and control group(P<0.05). Serum OPG and CRPlevel is significantly higher in KD patients with CAL than those without CAL(P<0.05), and serum ALB level was lower(P<0.05). Multivariate logistic regression results showed that OPG, CRP and ALB were risk factors of CAL in KD patients. Serum OPG, CRP and ALB levels of patients with acute KD were all reliable indicators to predict CAL development by ROC analysis(P<0.05).  Conclusion  Serum OPG is an independent risk factor of CAL for patients with KD, and may help to predict CAL in the acute phase of KD.
