Pseudohypoaldosteronism type 1 (PHA-1, MIM #264350) is caused by defective transepithelial sodium transport. Affected patients develop life-threatening neonatal-onset salt loss, hyperkalemia, acidosis, and elevated aldosterone levels due to end-organ resistance to aldosterone. In this report, we present a patient diagnosed as PHA-1 who had clinical and laboratory findings compatible with the diagnosis and had genetically proven autosomal recessive PHA-1. The patient received high doses of sodium supplementation and potassium-lowering therapies; however, several difficulties were encountered in the management of this case. The aim of this presentation was to point out the potential pitfalls in the treatment of such patients in the clinical practice and to recommend solutions.

Pseudohypoaldosteronism type II is a rare Mendelian disorder characterized by hypertension, hyperkalemia, hyperchloremia and metabolic acidosis, despite a normal glomerular filtration rate. Four genes (, , and ) are associated with this disease. Mutations in the gene cause pseudohypoaldosteronism type II in either an autosomal dominant or a recessive inheritance pattern.

Pseudohypoaldosteronism type 2 (PHA2) is a rare inherited condition of altered tubular salt handling. It is characterized by the specific constellation of hyperkalaemic hyporeninemic hypertension, hyperchloremic metabolic acidosis and hypercalciuria. Molecular genetic testing confirms the diagnosis in the majority of cases.

Introduction: Pseudohypoaldosteronism type 1b (PHA1B) is a rare autosomal recessive disease caused by dysfunction of amiloride-sensitive epithelial sodium channels (ENaC), that might present with a wide variety of pulmonary symptoms.
Methods: We provide a systematic review of published cases with PHA1B and respiratory symptoms, adding a relevant case from our clinic.
Results: Thirty-seven publications presenting 61 cases were identified apart from our case.
Pseudohypoaldosteronism type 1 (PHA1) is a rare, heterogeneous group of disorders characterized by resistance to aldosterone action. We report the case of a 17-day-old Saudi female infant who presented on the third day of life with persistent hyperkalemia, hyponatremia, and metabolic acidosis. Initial evaluation for congenital adrenal hyperplasia was unremarkable.
