Resistência aos mineralocorticóides: pseudo-hipoaldosteronismo tipo 1

Abstract: RESUMOPseudo-hipoaldosteronismo tipo 1 (PHA1) é uma doença genética rara, caracterizada por vômitos, desidratação, baixo ganho pôndero-estatural e perda urinária de sal no período neonatal. Indivíduos afetados apresentam hiponatremia, hipercalemia, aumento da atividade de renina plasmática e concentrações muito elevadas de aldosterona plasmática, secundárias a uma resistência renal ou sistêmica à aldosterona. A forma sistêmica do PHA1 é a mais grave, havendo necessidade de reposição de doses altas de NaCl. Os … Show more

“…8 This form is associated with autosomal recessive transmission. 6 ENaC is a hetero-multimeric protein formed by three subunits (alpha, beta, and gamma) and is expressed in multiple tissues: distal nephron, colon, sweat and salivary glands and epithelial lung cells. Therefore, this is a more severe condition because of a systemic mineralocorticoid resistance, with affected patients requiring extremely high doses of sodium to compensate their multiorgan salt wasting and sometimes fatal hyperkalemia.…”
