Abstract

Letter to the Editor in response to the article ‘Transient Pseudohypoaldosteronism in an Infant: A Case Report’ by T. Latt et al.

 

To the Editor,

We want to congratulate Latt and colleagues on the article describing a case of a patient with transient pseudohypoaldosteronism.1 Electrolyte derangements in course of this rare entity may be much more severe, as in our patient presenting with hyponatremia of 103 mmol/L. We feel that we can contribute to the topic by reporting our patient and discussing hyponatremia management.
