Two Cases of Salt Wasting Crisis in Newborn: Primary and Secondary Pseudohypoaldosteronism

Many disorders can cause life-threatening salt wasting crisis in newborns. In these cases, dehydration, electrolyte disturbances and shock are predominant in addition to the manifestations of the primary disease. The most dramatic of these syndromes is congenital adrenal hyperplasia while other causes are less common. Pseudohypoaldosteronism, a disorder caused by defective target organ effect of aldosterone is a rare cause of the salt wasting crisis. Salt wasting can occur through urine, sweat, saliva or intestinal secretions. It occurs primarily or secondary to other disorders. Here we report two cases; one is familial hypoaldosteronism, second is the pseudohypoaldosteronism secondary to Prune-belly syndrome.
