Giant coronary aneurysms due to Kawasaki disease: A case−control study

BACKGROUND: Epidemiologic features of giant coronary aneurysm due to Kawasaki disease and its risk factors are still not clear. METHODS: Sixty-six patients with giant coronary aneurysms were reported to a 15th nationwide survey of Kawasaki disease in Japan. With all other patients treated in the same hospital as a control group, odds ratios were calculated for certain potential risk factors. RESULTS: Infant males aged less than 1 year,neutrophil concentration among leukocyte, late administration of intravenous gammaglobulin (IVGG) therapy and additional administration of IVGGwere considered as risk factors of giant coronary aneurysms due to Kawasaki disease. In univariate analysis, use of IVGG therapy and a large amount of IVGG (2500+ mg/kg)elevated the risk, whereas the relationship disappeared after the adjustment. CONCLUSIONS: The observation of 66 cases with giant coronary aneurysms due to Kawasaki disease reported to the nationwide survey provides some risk factors and consideration about the aneurysms.     

上海地区1998－2002年川崎病流行病学特征

目的 对上海地区川崎病发病情况进行调查，了解中国发达地区川崎病的流行病学特征。方法 参照日本流行病学调查方案，制作统一调查表和诊断指南，调查对象为1998年1月1日－2002年12月31日上海地区50家有儿科临床服务的二级及二级以上医院收治的所有川崎病病例。结果 调查表回收率100％，将18例不符合表格填写要求者剔除后，对768例进行分析。上海地区5岁以下儿童川崎病发病率呈逐年增高趋势， 1998年为16.79/10万，1999年为25.65/10万，2000年为28.16/10万，2001年为28.05/10万，2002年为36.76/10万。男女性别比为1.83:1；发病年龄为1个月～18.8岁（中位数1.8岁），发病年龄高峰为9.6个月；全年均可发病，但以春夏之交较多见。主要症状表现为发热持续5 d以上者最为常见（99.3％），其后依次为口唇、口腔黏膜损害（83.5％）、指（趾）端脱皮（82.9％）、皮疹（81.0％）、结膜充血（78.4％）、颈部淋巴结肿大（69.3％）、肢端充血硬肿（48.1％），45.2％的病例有肛周脱皮。心血管损害发生率24.3％，以冠状动脉扩张最为常见，占68％，其次为冠状动脉瘤，占10%。急性期病死率为0.26%，死因为冠状动脉瘤破裂和急性心力衰竭。再发率为1.82%。 结论 上海地区川崎病发病率明显低于日本，但高于西方国家。发病率呈增高趋势，性别分布和心血管损害与其他报道相似。发病季节分布与北京地区的报道相似，但与其他报道不同。
