Résumé
Le syndrome de pseudo-Bartter, caractérisé par une alcalose hypochlorémique-hypokaliémique, mime les anomalies biochimiques du syndrome de Bartter sans atteinte rénale primaire. Il peut survenir suite à des vomissements chroniques au cours de la grossesse liés à des désordres psychiatriques. Il peut affecter aussi le foetus. L’absence de symptômes maternels due à l’installation lente des anomalies biochimiques au cours de la grossesse pourrait faire sousestimer de sérieux désordres électrolytiques présents chez la mère et son enfant à la naissance. Deux situations de cet ordre sont décrites où le diagnostic a été posé chez le nouveau-né et, a posteriori, chez sa mère. Les obstétriciens doivent rester attentifs aux signes de désordre alimentaire de leur patiente qui les minimise souvent.
Abstract
Pseudo-Bartter Syndrome is defined by a hypochloremic-hypokaliemic metabolic alkalosis but without primary tubular renal defects. This metabolic imbalance can result from a state of often hidden chronic vomiting in some psychiatric disorders. It can affect both the pregnant mother and her foetus. Owing to the paucity of symptoms due to the slow installation of these biochemical disturbances, a diagnosis of pseudo-Bartter syndrome could be missed at birth in the mother and her infant. This potential misdiagnosis could expose the mother and her baby to serious complications during the first hours of life. We report on two cases of neonatal pseudo-Bartter in which the diagnosis was made a posteriori in the mothers.
