Type 4 is associated with neurosensorial deafness. Until the present, indomethacin has not been introduced and the patient remains free of electrolyte imbalances. National Center for Biotechnology InformationU.

Indomethacin therapy and therapeutic amniocentesis usually allow the pregnancy to continue 3.

Rather, the expression denotes different variations such as antenatal Bartter syndrome, classic Bartter syndrome and Gitelman syndrome. Additionally, secondary hyperaldosteronism and hyperreninaemia with normal blood pressure were found.

Curr Opin Nephrol Hypertens ; Only the most activating mutations of the receptor are associated with engermedad salt wasting. Molecular studies allowed identification of different subtypes of the syndrome, depending on genes involved in defective synthesis of proteins responsible for transport of various ions across tubular cells. 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.

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.


Kidney Int ;72 9: Prenatal diagnosis can be made by documenting high chloride content of the amniotic fluid and mutational bartetr of genomic DNA extracted from cultured amniocytes obtained by amniocentesis 4,6. The primary pathogenic mechanism is a defective transepithelial chloride reabsorption at the thick ascending limb of loop of Henle.

As a result, treatment which must be life-long is aimed at minimising the effects of the secondary increases in prostaglandin and aldosterone production.

A complete and careful clinical history is of the utmost importance to reach a definitive diagnosis.

First Bartrer Philadelphia, PA: As a result, hypokalemia, metabolic alkalosis and hyperreninaemic hyperaldosteronism occurs with normal blood pressure Other search option s Alphabetical list. Acta Med Port ;24 Suppl 3: Inherited primary renal tubular hypokalemic alkalosis: Exact prevalence of Bartter syndrome with hypocalcemia is not known with very few patients so far described.

Síndrome de Gitelman

Iatreia ; 22 1: Renal biopsy is generally not an indication for the diagnosis eenfermedad Bartter syndrome. Currently, he is 21 months old and continues on a potassium supplement, having stopped the sodium supplementation at 4 months old. The cornerstones in treatment are long-term potassium chloride supplementation and non-steroidal anti-inflammatory drugs. A 31 weeks gestation baby was born from consanguineous parents. Discussion Phenotype is very variable in the classic Bartter syndrome, and more than half of the patients are diagnosed within the first year of life.

Patients poorly managed may develop a progressive tubulointerstitial nephropathy that can lead to terminal chronic renal failure.

Long-term outcome including mental development is usually normal 3. There is no specific treatment, correction of dehydration and electrolyte imbalance are the important aspects of management. 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.

As Bartter syndrome is an autossomal recessive disorder, genetic counselling should be offered to the families. Investigations 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.

Outcome and follow-up After a year of follow-up, there was a reduction of polyuria, stable GFR, gradual improvement of psychomotor development and growth, and plasma potassium and bicarbonate levels normalised.

Blood gases revealed hypochloraemic metabolic alkalosis, hyponatraemia and hypokalaemia.
