Bartter Syndrome Type I. Clinical Case of a Pregnant Woman with Polyhydramnios

Abstract

Bartter syndrome is an inherited renal tubular disorder characterized by salt wasting, hypokalemia and metabolic acidosis due to impaired salt reabsorption in the ascending limb of the loop of Henle in the renal nephrons. Currently, five types of the disease are known. While the clinical signs of type 3 (classical type) appear in childhood and later ages, types 1, 2, 4, 5 (antenatal type) are characterized by severe polyhydramnios in the antenatal period and antenatal fetal death. This article is about a pregnant woman carrying a fetus with antenatal Bartter syndrome type I.
