MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Intranasal corticosteroid (Nasacort) use during pregnancy for the treatment of seasonal allergies has increased over the past decade. Nasacort is now available over the counter since October 2013 in the US and January 2015 in Canada. Given that seasonal allergies are prevalent during pregnancy and that a medication available over-the-counter is likely to be used frequently, we aimed to study the risk of using Nasacort during gestation. Furthermore, given the potential public health impact, the objectives of our study were to assess the safety of intranasal triamcinolone exposure during pregnancy on the occurrence of major congenital malformations, small-for-gestational-age (SGA) newborn, and spontaneous abortions.
Use of intranasal triamcinolone during the first trimester of pregnancy was not significantly associated with the risk of overall congenital malformations (OR 0.88, 95%CI 0.60-1.28; 31 exposed cases) compared to non-exposure; it was however associated with the risk of respiratory defects (OR 2.71, 95%CI 1.11-6.64; 5 exposed cases). This is important given that a medication given for the treatment of respiratory diseases is associated with respiratory defects in newborns.
Pregnancy exposure to intranasal triamcinolone was not significantly associated with the risk of spontaneous abortions (OR 1.04, 95%CI 0.76-1.43; 50 exposed cases). No association was found between 2nd or 3rd trimester exposure to intranasal triamcinolone and the risk of SGA (OR 1.06, 95%CI 0.79-1.43; 50 exposed cases).
