Pseudohypoaldosteronism with increased sweat and saliva electrolyte values and frequent lower respiratory tract infections mimicking cystic fibrosis.
Four patients with severe pseudohypoaldosteronism caused by multiple end-organ resistance to aldosterone had frequently recurring lower respiratory tract infections and persistently elevated sweat and saliva electrolyte values. The increased saliva electrolyte values in these patients probably affect normal mucociliary function in the respiratory tract and facilitate the occurrence of frequent lower respiratory tract involvement. Patients with pseudohypoaldosteronism may require treatment similar to that for cystic fibrosis to prevent long-term respiratory complications.
