Transient pseudohypoaldosteronism with hyponatremia-hyperkalemia in infant urinary tract infection

PURPOSE: We describe an uncircumcised male infant and a female neonate treated for infant urinary tract infection who had multiple hormonal and electrolyte abnormalities consistent with the diagnosis of transient pseudohypoaldosteronism. MATERIALS AND METHODS: We retrospectively reviewed these 2 cases. RESULTS: In each case successful treatment of infant urinary tract infection was accompanied by the resolution of all hormonal and electrolyte abnormalities, including hyperaldosteronemia, hyperreninemia, hyponatremia and hyperkalemia. CONCLUSIONS: Because of future renal scarring, decreased renal function and possible hypertension, appropriate hormonal studies should be performed in infants with infant urinary tract infection who also have hyponatremia and hyperkalemia.
