本文用间接荧光法检查了99例临床疑似呼吸道合胞病毒(RSV)感染患儿鼻咽部脱落细胞RSV抗原,阳性率57.6%,与血清学检查比较,阳性符合率75.5%,说明该方法具有敏感快速的优点,对小婴儿RSV感染,可提高阳性诊断率。本文还观察了58例血清学检查阳性病例的临床特点,探讨了年龄、喘憋程度和恢复期血清RSV-IgG抗体滴度的关系,认为临床上小婴儿喘憋程度较重的原因似与血清中RSV-IgG抗体产生不足有关。
The indirect fluorescent method was used to examine the RSV antigen in nasopharyngeal exfoliated cells of 99 cases of children with clinical suspected RSV infection, the positive rate was 57.6%. Compared with the serological tests, the positive coincidence rate was 75.5%, indicating that this method has The advantage of being sensitive and fast can improve the positive diagnosis rate of RSV infection in infants. This article also observed the clinical features of 58 cases of serological positive cases, discusses the relationship between age, wheezing and convalescent serum RSV-IgG antibody titers, that the clinical severity of wheezing in infants and young children seemed similar to serum RSV-IgG antibodies in the lack of related.
