Women who received allergen-specific immunotherapy before or during pregnancy experienced no increased risk for adverse pregnancy outcomes, according to a study published in The Journal of Allergy and Clinical Immunology: In Practice.
“Our primary aim was to examine congenital malformations, though we did also study a variety of other pregnancy outcomes,” Niki Mitselou, MD, doctoral student in the department of pediatrics at Örebro University Hospital in Sweden, said in a press release.
The researchers examined data from 924,790 singleton pregnancies in Sweden between 2005 and 2014.
