We herein present a case of ABS whose diagnosis was early suspected due to familial and prenatal history. Correspondence to Dr Helena Vieira, moc. The tubular defect in Bartter syndrome cannot be corrected. Am J Med Sci ; 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.

Bartter-Gitelman syndromes and other inherited tubular transport abnormalities. The child was born after caesarean delivery, the Apgar score was 9 at 1st min and 10 at 5th min. Inherited primary renal tubular hypokalemic alkalosis: We wanted to leave a word of caution, namely to obstetricians and paediatricians 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.

Phenotype is very variable in the classic Bartter syndrome, and more than half of the patients are diagnosed within the first year of life. He presented hypochloremia, hyponatraemia, hyperkalemia up to D7, metabolic alkalosis after the first week of life and hypokalemia since D32 Table I.

On follow up, failure to thrive was observed, with an evolution for height and weight under percentile 3 based on the World Health Organization WHO child bagtter charts. Specialised Social Services Eurordis directory. At 11 months, the child was referred to the nephrology unit enfermedsd to persistence of clinical symptoms associated with metabolic alkalosis pH 7.


Despite being rare in clinical practice, which may lead to unnecessary medical investigation and diagnosis delay, in a child with failure to thrive, hypochloraemic metabolic alkalosis and hypokalaemia, this diagnosis must be considered. Please review our privacy policy. QJM ; 93 4: The neonatal period usually passes without major problems. Bartter, Gitelman, and Related Syndromes.

Later on, short stature, failure to thrive, nephrocalcinosis and hypercalciuria were detected. The long-term prognosis is generally good, but close attention to electrolyte balance, volume status and growth is recommended. Iatreia ; 22 1: In our patient, the diagnosis of ABS was suspected early due to the family history and pregnancy antecedents: Phenotype-genotype correlation in antenatal and neonatal variants of Bartter syndrome.

The cornerstones in treatment are long-term potassium chloride supplementation and non-steroidal anti-inflammatory drugs. Additional information Further information on this disease Classification s 4 Gene s 1 Other battter s 0. Genetics of hypercalciuric stone forming diseases. Only comments written in English can be processed. J Pediatr ; 3: The child presented with early failure to thrive less than the third percentile and severe regurgitation.

Neonatal Bartter syndrome type 1. Biochemical analysis of the amniotic fluid was not performed. A 31 weeks gestation baby was born from consanguineous parents.

Long-term outcome including mental development is usually normal 3. The fractional urinary excretion of bbartter, potassium and chloride were increased and hyperreninaemic hyperaldosteronism was observed.

Signs of chronic tubulointerstitial nephropathy can occur during evolution. Summary and related texts. Rather, the expression denotes different variations such as antenatal Bartter syndrome, classic Bartter syndrome and Gitelman dnfermedad. 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.

The infant was advised exclusive breastfeeding for 2. Nephrol Dial Transplant ; 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.


The typical features include early onset of fetal polyuria causing maternal polyhydramnios and preterm delivery, intrauterine growth restriction, postnatal polyuria, episodes of dehydration, nephrocalcinosis and osteopenia 2,3. Molecular studies allowed identification of different subtypes of the syndrome, depending on genes involved in defective synthesis of proteins responsible for transport of enefrmedad ions across tubular cells. J Bras Nefrol ;34 1: There was clinical improvement and plasma potassium and bicarbonate normalised.

Síndrome de Gitelman

Postnatally, patients usually exhibit hyposthenuria and rapid weight loss. 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.

Hyperplasia of the juxtaglomerular apparatus has been observed but can be mild or enfermead absent. Bartter syndrome type 5 Bartter syndrome type V Prevalence: Abstract Bartter syndrome is a group of rare autosomal-recessive disorders caused by a defect in distal tubule transport of sodium and chloride. Biochem Biophys Res Commun ; 3: Afterwards, he was transferred and followed in a ce hospital.

He had several complications in the neonatal period acute renal failure, sepsis, intestinal enfermedxd and resectionwith hyponatraemia and hypokalaemia, requiring transient supplements of sodium and potassium chloride, but after this period electrolyte imbalances were not found.
