L'œdème aigu du poumon chez des patientes en menace d'accouchement prématuré traitées par inhibiteurs calciques : place de facteurs prédisposants ou pharmacologiques spécifiques ?

Calcium channel blockers of the dihydropyridin's family have been associated with the onset of an acute pulmonary edema when they are used as a treatment of preterm labor. We report here four cases of pulmonary edema in pregnant women treated with nicardipine (Loxen) for preterm labor. The physiopathology of pulmonary edema, the pharmacology of calcium channel blockers of dihydropyridin's family and the detailed analysis of our cases and those of the literature make us discuss of the role of these agents and associated population and risk factors in such complication.     

Origine fœtale des maladies de l'adulte : quelle importance pour la pratique obstétricale ?

The Developmental Origins of Human Adult Disease are thought to be secondary to a perturbation of the embryonic or fetal development, which leads to metabolic disorders such as diabetes or hypertension at adulthood. Maternal undernutrition or overnutrition, repeated glucocorticosteroids administered to the mother, or placental dysfunction are the most frequently considered causal factors. Therefore, it is necessary that the obstetrician is aware of these phenomena, as this knowledge may contribute to the prevention of adult diseases. Little is known yet, on the pathophysiological or epigenetic mechanisms that lead to theses observations, and more studies are needed both in humans and animal models.
