Background: Pregnancy typically prohibits the specific immunotherapy (SIT) of various allergic conditions, with the exception of pre-existing Hymenoptera venom allergies. International consensus currently recommends the continuation of a well-tolerated SIT with insect venom during pregnancy, since there is a significant risk of anaphylaxis after insect stings with potentially dismal outcomes for mother and fetus.
Case report: We report on a 28-year old woman, becoming pregnant during specific immunotherapy with Hymenoptera venom. SIT was continued during pregnancy and a premature birth occurred at the 24th week.
Discussion and conclusion: Unfortunately, there are still conflicting opinions in Germany regarding SIT during pregnancy, and the decision to perform such therapy is entirely based on knowledge and/or level of comfort of the primary physician. Thus, obstetricians should closely work together with an allergologist in cases of pregnant women with insect sting allergies.
