Kaninde A, Grace ML, Joyce C, et al. - In this prospective study, researchers reviewed the clinical course, outcome and incidence of infantile salt wasting correlated with urinary tract infection (UTI) and/or urinary tract malformation (UTM) over a two‐year surveillance period on the island of Ireland. Infants under one year of age presenting for the first time with hyponatraemia (Na < 130 mmol/L) and/or hyperkalaemia (K > 5.0 mmol/L) associated with urosepsis/UTM have been identified. Salt wasting is a rare complication of UTI, particularly when associated with underlying UTM. Boys seem to be at particular risk.
