应用间接ＥＵＳＡ法测定９６例小儿病毒性心肌炎柯萨奇病毒Ｅ特异性ＩｇＭ（ＣＶＢ。－ＩＭ牡）。结果阳性３０例，总阳性率３１．３％：１９例健康儿中有１例阳性，阳性率５．３％，两者比较差异有显著意义（ｘ＝４，２０，Ｐ＜０．０５）病程＜２月者阳性率为４２．４％（２８／６６例）．病程２～６月者阳性率为７．７（１／１３例），病程＞６月者阳性率为５．９％（１／１７例）．后两组与病程＜２月组比较差异均显著（分别为４，９．６．６１，Ｐ均＜（０．０５）。提示ＣＶＢ－ＩＭ测定对小儿病毒性心肌炎病原学的早期诊断有临床意义
Indirect EUSA method was used to detect Coxsackievirus E-specific IgM (CVB.-IM) in 96 pediatric patients with viral myocarditis. The positive rate was 31.3%. The positive rate was 5.3% in 19 healthy children. The difference was significant (x = 4,20, P <0.05) Duration of <2 months positive rate was 42.4% (28/66 cases). The positive rate was 7.7% (1/13 cases) in 2 ~ 6 months and 5.9% (1/17 cases) in duration> 6 months. The difference between the latter two groups and the course of <2 months was significant (4,9.6.61 respectively, P <0.05), which indicated that the CVB-IM was clinically useful in the early diagnosis of pediatric viral myocarditis etiology significance
