新华社华2月8日消息（记者任海军） 8日公布的一项研究成果显示，与从未接触过艾滋病病毒环境的婴儿相比，那些曾接触过母体艾滋病病毒环境但自身未感染的婴儿的抵抗力较差。这项研究成果9日将发表在《美国医学会杂志》上。
英国帝国理工学院的研究人员分析了母体艾滋病病毒感染与母亲及婴儿体内特异性抗体水平之间的关系。这项研究于2009年3月至2010年4月在南非西开普省开展，研究对象包括109名已感染及未感染艾滋病病毒的妇女及其子女。在新生儿16周时，研究人员提取他们的血清样品，测试其特异性抗体水平。
研究人员发现，与未接触过艾滋病病毒的婴儿相比，曾接触但未感染艾滋病病毒的婴儿体内针对Ｂ型流感嗜血杆菌、百日咳杆菌、肺炎球菌和破伤风杆菌的特异性抗体的水平较低。
研究人员表示，接触过艾滋病病毒但并未感染的婴儿代表了一个脆弱群体，他们下呼吸道感染和脑膜炎的发病率会增加，第一年的死亡率是普通婴儿的数倍。这项研究成果可以解释为何这部分婴儿拥有较高的发病率和死亡率。

Xinhua News Agency, China Feb. 8 (Xinhuanet Ren Haijun) 8 to a study released Tuesday shows that the environment and never had contact with HIV than babies who have been exposed to the environment but maternal HIV infection in infants not their own Resistance is poor. 9 results of this study will be published in "Journal of the American Medical Association"on.
Researchers at Imperial College London analyzed the maternal HIV infection and the body of the mother and baby relationship between the level of specific antibodies. The study in March 2009 to April 2010 the Western Cape Province in South Africa carried out study including 109 who had HIV infection and uninfected women and their children. 16 weeks in the newborn, the researchers extracted their serum samples were tested for specific antibody levels.
The researchers found that HIV has not been exposed infants compared to previous exposure of infants infected with HIV but not the body against Haemophilus influenzae type B, pertussis, pneumococcal and tetanus bacilli, low levels of specific antibodies .
The researchers said the exposed but not infected with HIV represent a vulnerable group and the baby, they lower respiratory tract infections and will increase the incidence of meningitis, the first year of infant mortality rate is several times more than ordinary. The findings may explain why this part of the infant has a high morbidity and mortality.
