Asymptomatic hyperkalemia as a form of presentation of pseudohypoaldosteronism. An Pediatr (Engl Ed). 2022 Mar;96(3):263-264http://hdl.handle.net/10668/21916In the paediatric age group, hyperkalaemia tends to be asymptomatic, so serum potassium levels greater than 5.5 mEq/L should be verified and investigated, as they may be indicative of potentially severe diseases, as occurred in the case presented here.1 The patient was a boy aged 5 years with a personal history of obesity and type 1 diabetes in whom a blood chemistry panel ordered during a check up revealed a serum potassium level of 6.8 mEq/L in absence of other electrolyte abnormalities. A second test confirmed the finding of hyperkalaemia. Previous blood tests have not found abnormal levels of this ion, and the patient had been asymptomatic at all times.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/PotassiumSerumAge GroupsHematologic TestsDiabetes Mellitus, Type 1FemaleHumansHyperkalemiaHyponatremiaMalePseudohypoaldosteronismresearch article35256312open accessPotasioElectrólitosPruebas hematológicasObesidadDiabetes Mellitus tipo 110.1016/j.anpede.2021.02.0112341-2879https://doi.org/10.1016/j.anpede.2021.02.011
