Infections During Pregnancy May be Twice As Likely to Cause Autism: Study

美国哥伦比亚大学梅尔曼公共卫生学院官网日前发布公告称,该校科学家与挪威公共卫生研究院合作开展的一项研究显示,怀孕初期感染过单纯性疱疹病毒2型(HSV-2)的孕妈妈,生出自闭症谱系障碍(ASD)男孩的风险比没感染的妈妈高出一倍,首次为孕期感染该病毒与自闭症存在高度关联提供了免疫学证据。研究结果刊登在22日出版的美国微生物学会期刊《mSphere》上。

A Columbia University study released on Wednesday said women who had infections early in pregnancy may be twice likely to have a child with autism.

"We believe the mother's immune response to HSV-2 (herpes simplex type 2) could be disrupting fetal central nervous system development, raising risk for autism," said the research team leader Milada Mahic to NBC News.

For instance, the Zika virus can infect a developing baby's brain and some viruses may cause severe birth defects, including brain damage, according to the research.

The research was published in the journal mSphere, a U.S. journal that makes fundamental contributions to microbial sciences.

However, some experts drew a different conclusion. Ian Lipkin, an infectious disease expert at Columbia University oversaw the research and believes that it's actually the mother's immune response that causes the damage.

The chemicals made by inflammation cross the placenta and directly affect the developing brain of the fetus, Lipkin said.

Autism refers to a broad range of symptoms, including relatively mild social awkwardness of Asperger's syndrome, profound mental retardation which debilitates repetitive behaviors and an inability to communicate.
