应用 Ｐ Ｃ Ｒ 和 Ｅ Ｌ Ｉ Ｓ Ａ 技术对３２ 例急性特发性血小板减少性紫癜（ Ｉ Ｔ Ｐ） 患儿的外周血进行了人细小病毒 Ｂ１９（ Ｈ Ｐ Ｖ Ｂ１９） 、 Ｅ Ｂ 病毒（ Ｅ Ｂ Ｖ） 、巨细胞病毒（ Ｃ Ｍ Ｖ） 及乙型肝炎病毒（ Ｈ Ｂ Ｖ） 系列检测。结果：病例组 Ｈ Ｐ Ｖ Ｂ１９ Ｄ Ｎ Ａ 阳性８ 例（２５ ．０ ％ ） ，与正常对照组比较有显著性差异（ Ｐ＜ ０ ．０５） 。 Ｅ Ｂ Ｖ Ｄ Ｎ Ａ 阳性２ 例， Ｃ Ｍ Ｖ Ｄ Ｎ Ａ 阳性３ 例， Ｈ Ｂｓ Ａｇ 和 Ｈ Ｂｅ Ａｇ 同时阳性２ 例，４种病毒的总阳性率为４６ ．９ ％ （１５／３２ 例） 。提示：近半数儿童 Ｉ Ｔ Ｐ 病例的发生可能与上述病毒感染有关，而 Ｈ Ｐ Ｖ Ｂ１９ 较其他病毒与 Ｉ Ｔ Ｐ 的关系更为密切。
Peripheral blood samples from 32 children with acute idiopathic thrombocytopenic purpura (ITP) were tested for the presence of human parvovirus B19 (H P V B19) and E B virus (E E) using the P C R and E L I S A techniques B V), cytomegalovirus (C M V) and hepatitis B virus (H B V) series of tests. Results: There were 8 cases (25.0%) positive for H P V B19D N A in the case group, which were significantly different from the normal control group (P0.05). 2 cases were positive for E B V D N A, 3 cases were positive for C M V D N A, 2 cases were positive for H Bs Ag and H Be Ag, and the total positive rate of 4 kinds of viruses was 46%. 9% (15/32 cases). Hint: Nearly half of children with ITP cases may be related to the above virus infection, and HpVB19 more closely related to other viruses and ITP.
