Pregnancy represents a unique immune tolerant condition that cannot be attributed merely to generalized immunosuppression. However, research released just before the start of this flu season indicates that, in the case of the flu, the opposite may be true during pregnancy.It is a given that, during pregnancy, women have more problems, and are more likely than other demographic groups to die from complications after the flu. A variety of mechanisms have been described, ranging from the non-self recognition, immunomodulation of specific inflammatory cell populations and a Th2-directed shift of the immune response, which are mediated by both localized and systemic mediators.
In the past, scientists have speculated that this is from a pregnancy-induced suppression of the immune system. Furthermore, an inflammatory response directed toward the conceptus is no longer considered an obligatory deleterious response; instead, it is considered an important factor that is necessary for normal growth and development. These immunomodulatory changes during pregnancy may also affect concurrent conditions and alter the course of inflammatory diseases.
Herein, we review the main immunomodulatory changes that occur during pregnancy and their effect on coexisting inflammatory conditions, with a specific focus on gastrointestinal disorders. Intrahepatic cholestasis of pregnancy: changes in maternal-fetal bile acid balance and improvement by ursodeoxycholic acid. It should be noted that the research did not only measure a woman’s response to the flu itself, but also the response women experienced during pregnancy after the flu vaccine, according to the text of the actual Stanford research.“Intriguingly, these differences were present prior to influenza vaccination and were further enhanced after vaccination. Specifically, the researchers analyzed the immune responses of 21 women during pregnancy against the immune responses of 29 women who were not pregnant. They studied the pregnant women just before being vaccinated with an inactivated flu vaccine, seven days after administration of the flu vaccine, and six weeks after giving birth.
