Amirlak I, Dawson KP. Additional information Further information on this disease Classification enferemdad 4 Gene s 1 Other website s 0. The newborn developed polyuria, dehydration, electrolyte imbalances and metabolic alkalosis. The child presented with early failure to thrive less than the third percentile and severe regurgitation. Hypocalcaemia may be asymptomatic or associated with paresthesias, carpopedal spasm, and seizures.
Early intervention and specific treatment options play a great role in reducing ve complication rates of the affected neonates and should be initiated as soon as possible 7. Table 1 Laboratory tests on Nephrology Unit admission.

He was the second child of consanguineous parents within the third degree, but otherwise healthy. Correspondence to Dr Helena Vieira, moc. Health care resources for this disease Expert centres Diagnostic tests 29 Patient organisations 34 Orphan drug s 1.
Pediatric Oncall ;6 8: The molecular study revealed a genetic mutation in ClC-Kb, confirming that it was the classic form of Bartter syndrome. Int J Pediatr ; doi: Additionally, secondary hyperaldosteronism and hyperreninaemia with normal blood pressure were found. Although the molecular study was not performed, he started indomethacin and potassium supplement, improving his appetite and weight.

Prenatal diagnosis can be made fe documenting high chloride content of the amniotic fluid and mutational analysis of genomic DNA extracted from cultured amniocytes obtained by amniocentesis 4,6. With the clinical diagnosis of Bartter syndrome, the child began therapy with increasing supplementation of potassium chloride, in order to normalise plasma potassium levels, to which was later added indomethacin.
As a result, hypokalemia, metabolic alkalosis and hyperreninaemic hyperaldosteronism occurs barfter normal blood pressure Bartter syndrome with hypocalcemia is a very rare manifestation of autosomal dominant hypocalcemia ADH; see this term. Genetics of hypercalciuric stone forming diseases.

The increased arrival of fluid to more distal bbartter secreting sites will promote kaliuresis. Generally, the use of prostaglandin synthetase inhibitors is required to control disease, indomethacin being the most recommended and well tolerated in children.
Pregnancy was complicated by severe polyhydramnios at 24 weeks, which led to hospitalization and therapeutic amniodrainage at 28 weeks of gestation. Exact prevalence of Bartter syndrome with hypocalcemia is not known with very few patients so far described. A premature newborn male was born at 31 weeks and 3 days of enferrmedad.

Despite the hyperkalaemia detected during the first week of life, it could have been confused with badtter or pseudohypoaldosteronism type I, the presence of a normal blood pressure was consentaneous with type II ABS.
She began therapy with potassium chloride supplementation and indomethacin. Patients poorly managed may develop a progressive tubulointerstitial nephropathy that can lead to terminal chronic renal failure. Clearly, this channel malfunction will cause an altered transport of sodium and chloride in the distal nephron. The neonatal period usually passes without major problems.
Unexplained polyhydramnios between 24 and 30 weeks of gestation, without apparent foetal or placental abnormalities should lead to the suspicion of this entity 3.
Perinatal period was uneventful. Curr Opin Nephrol Hypertens ; Inherited primary renal tubular hypokalemic alkalosis: Early Human Development86 suppl: Signs of chronic tubulointerstitial nephropathy can occur during evolution.
