A world-first study has found low-dose aspirin may treat flu-induced blood vessel inflammation, creating better blood flow to the placenta during pregnancy. Animal studies examined whether the treatment for preeclampsia could be applied to flu infections – and the results, according to the research team, were very promising. Lead researcher and RMIT Post-Doctoral Research Fellow, Dr Stella Liong, said flu infections during pregnancy can resemble preeclampsia, a pregnancy complication that causes inflammation to the aorta and blood vessels.
Low-dose aspirin is commonly taken to prevent preeclampsia, as it stops the body from creating chemicals that cause inflammation. When the vascular system is inflamed, it leads to poor blood flow and affects the aorta's function. This is especially a problem during pregnancy where good blood flow to the placenta is crucial to the development of the fetus.
" Dr. Stella Liong, Lead Researcher and RMIT Post-Doctoral Research Fellow The research, led by RMIT University in collaboration with Trinity College Dublin, Ireland Professor John O'Leary and University of South Australia Professor Doug Brooks, found fetuses and placenta from mice with influenza A were smaller than those from uninfected mice. Markers of low oxygen to the blood and poor blood vessel development were also evident in the fetuses.
However, mice treated daily with low-dose aspirin had less inflammation and improved fetal development and offspring survival. While the research .
