Spontaneous delivery occurred at 31 weeks gestation, made through caesarean section because of breech presentation. Long-term outcome including mental development is usually normal 3. The cornerstones in treatment are long-term potassium chloride supplementation and non-steroidal anti-inflammatory drugs. The family history was snfermedad minor and atopy, with no consanguinity. 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.

Open in a separate window. Nephrol Dial Transplant ; At 5 months, following hospital admission for acute gastroenteritis with mild dehydration with metabolic alkalosis pH 7. A 31 weeks gestation baby was born from consanguineous parents. Postnatally, patients usually exhibit hyposthenuria and rapid weight loss. enfermmedad

Classic Bartter syndrome: a rare cause of failure to thrive in a child

The ClC-Kb is located in the basolateral membrane of distal tubular cells and allows the passage of chloride from the cell into the bloodstream. Signs of chronic tubulointerstitial nephropathy can occur during evolution. Pediatric Oncall ;6 8: We herein present a case of ABS whose diagnosis was early suspected due to familial and prenatal history.

The primary pathogenic mechanism is a defective transepithelial chloride reabsorption at the thick ascending limb of loop of Henle. There are two distinct clinical presentations: On the other hand, we also observed transient hyperkalemia that may be also occur in type II ABS 1,3,7.

Laboratory examination shows a typical constellation of metabolic alkalosis, low normal chloride levels, hypokalaemia, and hypomagnesaemia; urine analysis shows hypocalciuria. Major derangements are severe dehydration, hyponatremia, hypochloremia, hypokalaemia and metabolic alkalosis.

The authors present the case of an month-old child with early failure to thrive and severe regurgitation.

The infant was advised exclusive breastfeeding enfermdad 2. Afterwards, he was transferred and followed in a secondary hospital. 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.

Acta Med Port ;24 Suppl 3: The neonatal period usually passes without major problems. There was clinical improvement and plasma potassium and bicarbonate normalised.

Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Hyperaldosteronism will also stimulate potassium secretion, thus closing the pathogenic circle.

Later on, short stature, failure to thrive, nephrocalcinosis and hypercalciuria were detected. Devuyst O, Pirson Y.

Síndrome de Gitelman

Additionally, secondary hyperaldosteronism and hyperreninaemia with normal blood pressure were found. Gastrointestinal side effects such as gastritis and peptic ulcers are the main drawbacks brtter prolonged indomethacin therapy.

This disorder is usually severe in the neonatal period and early childhood but it improves gradually which allows to reduce the intensity of treatment or stop it for a period1.

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.

QJM ; 93 4: Pregnancy was complicated with polyhydramnios at 24 weeks of gestation. The combination of hyperaldosteronism and increased distal flow enhances potassium and hydrogen secretion, causing hypokalaemia and metabolic alkalosis.

Between these two endermedad, the classic Bartter syndrome presents as a disorder with intermediate severity. Unexplained metabolic alkalosis and hypokalemia: National Center for Biotechnology InformationU.
