[Differential diagnosis in hypokalemia. A case of Liddle syndrome].
A case of Liddle's syndrome showing weakness, hypertension, metabolic alkalosis and hypokalemia, identifiable as Liddle's syndrome, allows us to face the differential diagnosis among ionic dysfunctions, as primitive and secondary hyperaldosteronism, hypercorticism and pseudohyperaldosteronism. We discuss hypokalemia due to reduced potassium pool, or referable to altered ionic redistribution without losses. Concerning the treatment of important hypokalemia, we face manners and times of intravenous administration of potassium salts, potassium-sparing diuretics and supplementation per os; besides, we stress the dietetic contribution of rich in potassium foods, for the correction of the light hypokalemia and against deficit of pool referable to the long-term diuretic therapy.
