Study Question: Is there an association between dydrogesterone exposure during early pregnancy and the reporting of birth defects?
Summary Answer: This observational analysis based on global safety data showed an increased reporting of birth defects, mainly hypospadias and congenital heart defects (CHD), in pregnancies exposed to dydrogesterone, especially when comparing to progesterone.
What Is Known Already: Intravaginal administration of progesterone is the standard of care to overcome luteal phase progesterone deficiency induced by ovarian stimulation in ART. In recent years, randomized controlled clinical trials demonstrated that oral dydrogesterone was non-inferior for pregnancy rate at 12 weeks of gestation and could be an alternative to micronized vaginal progesterone.
Introduction And Objective: Proton pump inhibitor (PPI) use in children increases the risk of infections, prompting inquiry into the impact of prenatal PPIs exposure on serious infections in offspring. As a research gap in this area exists, this study aimed to address it by assessing the association between prenatal PPIs exposure and serious infections in infants during their first year of life.
Methods: Using the French health insurance data warehouse (SNDS) (2013-2018), we conducted a retrospective cohort study on singleton, full-term liveborn non-immunocompromised infants, stratified by PPI use during the first three months of life (early-life use).
Objectives: Fluoropyrimidine-based therapies, 5-fluorouracil (5-FU) and its oral prodrugs, capecitabine and tegafur/oteracil/gimeracil (S-1), are pivotal drugs to treat gastric cancer. Fluoropyrimidines are associated with cardiotoxicity including ischemic cardiopathy. The mechanisms of ischemic cardiopathy are considered to be multifactorial, potentially involving metabolites of 5-FU generated by the dihydropyrimidine dehydrogenase (DPD).

- * Researchers excluded pregnancies that ended in termination or miscarriage and those with prior blood cancer histories, focusing on the survival rates and maternal health during these malignancies compared to healthy pregnancies.
- * The study found that of nearly 10 million pregnancies analyzed, 1,366 were associated with haematological cancers, providing new insights into their incidence and effects on maternal morbidity and mortality.
