RESUMO
Antenatal Bartter syndrome is a rare condition that affects approximately 1.2 individuals per million. It is caused by renal tubular dysfunction that impairs the reabsorption of sodium and chloride. This results in various symptoms such as polyuria, vomiting, dehydration, and failure to thrive. Because of its low prevalence, diagnosing this disorder can be challenging for medical professionals. In this report, we describe a rare case of a 3-month-old female infant who had symptoms of Bartter syndrome, such as severe hypotension, facial flattening, cough, and seizures. She also had the typical features of the condition, except for prematurity and hypercalciuria, which were not present. In this case, we highlight the importance of regular follow-ups and monitoring of patients with dehydration and electrolyte imbalances, as these can lead to complications in Bartter syndrome. Early intervention and close monitoring can enhance patient outcomes and avoid complications.
