Case presentation An month-old female child was presented. Blood pressure was normal and polyuria was documented. Summary Epidemiology Exact prevalence of Bartter syndrome with hypocalcemia is not known with very few patients so far described.

Type 4 is associated with neurosensorial deafness. Signs of chronic tubulointerstitial nephropathy can occur during evolution. The tubular defect in Bartter syndrome cannot be corrected. J Bras Nefrol ;34 1: The typical features include early onset of foetal polyuria causing maternal polyhydramnios and preterm delivery, intrauterine growth restriction, postnatal polyuria and dehydration, nephrocalcinosis and osteopenia.

The definitive diagnosis is performed with molecular analysis. Only comments written in English can be processed. Biochemical analysis of the amniotic fluid was not performed.

Nat Clin Pract Nephrol ; 4: The neonatal period usually passes without major problems. The ABS is a rare entity but it should be suspected in any neonate with antenatal history of unexplained and rapidly increasing polyhydramnios in the late second trimester, that presents during the early neonatal period with polyuria and severe dehydration.

There was clinical improvement and plasma potassium and bicarbonate normalised. Background Bartter battter is a group of rare autosomal-recessive disorders with a unifying pathophysiology caused by a defect in one of the transporters involved in distal tubule transport of sodium and chloride.

Molecular studies allowed identification of different subtypes of the syndrome, depending on genes involved in defective synthesis of proteins responsible for enfermead of various ions across tubular cells. Pregnancy enffermedad complicated by severe polyhydramnios at 24 weeks, which led to hospitalization and therapeutic amniodrainage at 28 weeks of gestation. In our patient, the early suspicion of diagnosis allowed the anticipation and more aggressive correction of dehydration and electrolyte imbalances, being aware that potassium supplements are usually needed by weeks of age 1,7,9.

Currently, he is 21 months old and continues on a potassium supplement, having stopped the sodium supplementation at 4 months old. The resulting hypokalaemia will stimulate prostaglandin synthesis, which in turn will induce compensatory increases in the activity of the renin, angiotensin and adrenergic systems to maintain blood pressure.

Genetics of hypercalciuric stone forming diseases. The renal ultrasound at D3 was normal and at D36 was suggestive of macroscopic nephrocalcinosis both renal sinuses had hyper-reflected spots ; at 8 months medullary nephrocalcinosis was confirmed the medullary pyramids were hyperechoic, bilaterally, and cortical thickness was preserved with no signs of hydronephrosis.

Am J Med Sci ; Hypocalcaemia may be asymptomatic or associated with paresthesias, carpopedal spasm, and seizures. Bartter syndrome is a group of rare autosomal-recessive disorders caused by a defect in distal tubule transport of sodium and chloride.

Furthermore, nearly all ABS patients develop medullary nephrocalcinosis within the first month of life 1which was also observed emfermedad us. Potassium supplements were introduced at D Afterwards, he was transferred and followed in a secondary hospital. The increased arrival of fluid to more distal potassium secreting sites will promote kaliuresis.

Foetal karyotype was 46, XY normal.

A premature newborn male was born at 31 weeks and 3 days of gestation. Kidney Int ;72 9: Only the most activating mutations of the receptor are associated with significant salt wasting. Hyperplasia of the juxtaglomerular apparatus has been observed but can be mild or even absent. Although the molecular study was not performed, he started indomethacin enfeemedad potassium supplement, improving his appetite and enfermedda.

Our case report presented all those features. Unexplained metabolic alkalosis and hypokalemia: Rev Fac Med ;19 2: In a child with failure to thrive, hypochloraemic metabolic alkalosis and hypokalaemia, this diagnosis must be considered. The newborn was discharged on the 6 th week of life, so we decided not to start indomethacin because of the risk of necrotizing enterocolitis and acute renal failure before this age 1,3,7.

The investigation revealed negative allergology study, normal sweat test, negative antitransglutaminase antibody, abdominal and kidney ultrasound without changes, including nephrocalcinosis and endoscopy with incompetent cardia and normal intestinal biopsy. 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. Summary and related texts.

Investigations The investigation revealed negative allergology study, normal se test, negative antitransglutaminase antibody, abdominal and kidney ultrasound without changes, including nephrocalcinosis and endoscopy with incompetent cardia and normal intestinal biopsy.

His older brother, also born preterm, had nephrocalcinosis and hypercalciuria attributed to prematurity and its complications. The documents contained in this web site are presented for information purposes only. Treatment 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.

Blood pressure is typically normal.

The long-term prognosis is generally ve, but close attention to electrolyte balance, volume status and growth is recommended. The majority of children with a timely and appropriate therapy have clinical improvement and catch up growth. QJM ; 93 4:
