Antenatal Bartter syndrome also called hyperprostaglandin E syndromeis characterised by the additional features of maternal polyhydramnios, prematurity, severe polyuria, high urinary calcium excretion, nephrocalcinosis and very elevated levels of prostaglandin E2 in the blood and urine.

Open in a separate window. The combination of hyperaldosteronism and increased distal flow enhances potassium and hydrogen secretion, causing hypokalaemia and metabolic alkalosis.

The mother can be treated antenatally with indomethacin, which improves the prognosis 3,4. The birth weight of the baryter was g, which was appropriate for gestational age. GFR, glomerular filtration rate. Bartter syndrome type 5 Bartter syndrome type V Prevalence: Pregnancy was complicated with polyhydramnios at 24 weeks of gestation.

Additional information Further information on this disease Classification s 4 Gene s 1 Other website s 0.

In classic Bartter syndrome symptoms start during the first 2 years of life as polyuria, polydipsia, vomiting, constipation, salt craving, tendency to dehydration, muscular hypotonia, lethargy, developmental delay and failure to thrive.

Acta Med Port ;24 Suppl 3: We report a case of classic Bartter syndrome with delayed diagnosis, successful treatment and molecular study.

We wanted to leave a word of caution, namely to obstetricians and enferemdad as to the importance of making a complete and careful clinical history, because ABS manifestations can be neglected and mislead by the diagnosis of prematurity. On the other hand, we also observed transient hyperkalemia that may be also occur in type II ABS 1,3,7. Type 4 is associated with neurosensorial deafness.


Classic Bartter bartteer is a rare disease, which may lead to unnecessary medical investigation and diagnosis delay. The tubular defect in Bartter syndrome cannot be corrected.

The molecular study revealed a genetic mutation in ClC-Kb, confirming that it was the classic form of Bartter syndrome. There is no specific treatment, correction of dehydration and electrolyte imbalance are the important aspects of management.

Síndrome de Bartter antenatal

A 31 weeks gestation baby was born from consanguineous parents. Curr Opin Nephrol Hypertens ; Am J Med Sci ; The child presented with early failure to thrive less than the third percentile and severe regurgitation. Despite the hyperkalaemia detected during the first week of life, it could have been confused with hypoaldosteronism or pseudohypoaldosteronism type I, the presence of a normal blood pressure was consentaneous with type II ABS. 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 typical features include early onset of foetal polyuria causing maternal polyhydramnios and preterm delivery, intrauterine growth restriction, postnatal polyuria enfermddad dehydration, nephrocalcinosis and osteopenia.

First Edition Philadelphia, PA: J Pediatr ; 3: Please review our privacy policy. Bartter syndromes and other salt-losing tubulopathies. As a result, treatment which must be life-long is aimed at minimising the effects of the secondary increases in prostaglandin and aldosterone production. Abstract Bartter syndrome is a group of rare autosomal-recessive disorders caused by a defect in distal tubule dd of abrtter and chloride.

Currently, he is 21 months old and continues on a potassium supplement, having stopped the sodium supplementation at 4 months old. Prenatal diagnosis can be made by documenting high chloride content of the amniotic fluid and mutational analysis of genomic DNA extracted from cultured amniocytes obtained by amniocentesis 4,6.

Pregnancy was complicated by severe polyhydramnios at 24 weeks, which led to hospitalization and therapeutic amniodrainage at 28 weeks of gestation. Check this box if you wish to receive a copy of your message.


J Bras Nefrol ;34 1: 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. Geary DF, Schaefer F, editors.

Laboratory tests revealed table 1 normal glomerular filtration rate GFRincreased urinary chloride, increased fractional sodium and potassium excretion, slightly increased urinary calcium, normal plasma magnesium and increased plasma renin and aldosterone. Discussion Phenotype is very variable in the classic Bartter syndrome, and more than half of the patients envermedad diagnosed within the first year of life.

Síndrome de Gitelman

Int J Pediatr ; doi: Later on, short stature, failure to thrive, nephrocalcinosis and hypercalciuria were detected. Generally, the use of prostaglandin synthetase inhibitors is required to control disease, indomethacin being the most recommended and well tolerated in children.

Kleta R, Bockenhauer D. National Center for Biotechnology InformationU. The newborn was admitted at the intensive care unit because of prematurity.

With the clinical diagnosis vartter 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. Neonatal Bartter syndrome type 1.

Laboratory examination shows a typical constellation of metabolic alkalosis, low normal chloride levels, hypokalaemia, and hypomagnesaemia; urine analysis shows hypocalciuria. Background Bartter syndrome 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.

Antenatal Bartter syndrome results from disturbed salt reabsorption along the thick ascending limb of Henle TAL due to defects either in the NKCC2 sodium-potassium-chloride co-transporter gene, renal outer medullary potassium channel potassium ion channel gene, barttin or both ClC-Ka and ClC-Kb chloride ion channel genes.
