Future mums needed for study into influenza and pregnancy

The study, funded by the National Health and Medical Research Council, aims to determine why pregnant women are so vulnerable to viral infections like influenza.

“Pregnant women tend to experience more severe bouts of influenza and swine flu than non-pregnant women,” Professor Peter Wark*, co-investigator on the study, said.

“The rate of hospitalisation among pregnant women infected with influenza is four times that of the general population, and if those women develop pneumonia up to 20 per cent require intensive care treatment.” 

The research team is seeking women who are intending to become pregnant, and are able to visit John Hunter Hospital to provide blood samples before, during and after their pregnancy.

“We suspect part of the changes in the immune system that occur with pregnancy also make it difficult for a pregnant woman to fight viral inflections,” Professor Wark said.

Co-investigator Professor Roger Smith** said he hoped the team’s findings would help guide emergency therapy of women infected with influenza.

“It is very important we understand exactly why pregnant women are more vulnerable to influenza infections if we are going to develop better methods of preventing viral diseases during pregnancy,” Professor Smith said.

“In the 2009 (H1N1) influenza pandemic, 50 per cent of the pregnant women infected worldwide were hospitalised.  Of those, 23 per cent were admitted to an Intensive Care Unit and eight per cent died.”

“Next time there is a pandemic we want to be able to better protect pregnant women.”
