Antenatal Bartter syndrome typically presents with polyhydramnios and preamture delivery. Prenatal diagnosis is very difficult. [scinapse.io]

The initial work-up was done to exclude surgical and renal causes of her presentation, and the diagnosis was confirmed by gene analysis to be type III—classic Bartter syndrome. [casereports.bmj.com]

Antenatal BS is characterized by in utero or neonatal age of presentation, presence of nephrocalcinosis, higher urinary loss of sodium, potassium, and chloride. Classical BS presents at a later age and is milder in course. [indianjnephrol.org]

Antenatal Bartter syndrome is a rare condition that can present with different clinical features. [ncbi.nlm.nih.gov]

• Weakness

  In addition, patients can experience muscle weakness and cramping as well as hearing loss and intellectual disability. With treatment available, life expectancy is not reduced. No genotype-phenotype correlation has been reported. [sema4.com]

  The commonest are lethargy, transient weakness and/or tetany, paresthesiae, thirst and joint pains due to chondrocalcinosis. Blood pressure is usually lower than normal. Sudden cardiac arrest may occur. [rarerenal.org]

  Some common ones include: Constipation Frequent urination Generally feeling unwell Muscle weakness and cramping Salt cravings Severe thirst Slower than normal growth and development Antenatal Bartter syndrome may be diagnosed before birth. [webmd.com]

  Mutations in these genes can cause a loss of salt in the urine Some of the symptoms of Bartter Syndrome are increased urine volume, increased urine frequency, dehydration, constipation, reduced potassium levels, weak bones, and muscle spasms The syndrome [dovemed.com]

  So, therefore, you are looking at muscle weakness and heart issues. Do not forget that. In general, hypokalema you should know always causes muscle weakness for reasons we just talked about. [lecturio.com]

• Short Stature

  To help treat short stature and growth delays, hormone therapy may be recommended. Speech and occupational therapy can improve dexterity and daily living skills. Renal therapy and kidney support treatments may be necessary. [verywell.com]

  The pediatrician told us that Ethan was tiny because he was on soy milk formula and his vomiting was due to a condition called cyclic vomiting. We believed different; a Mother’s Intuition knew something was wrong with our baby boy. [barttersyndromefoundation.org]

  After two weeks he was re- admitted a third time as vomiting and dehydration were not relieved. [jpma.org.pk]

• Polydipsia

  […] along with: hypokalemia metabolic alkalosis hypotension or normotension elevated plasma renin elevate aldosterone antenatal polyhydramnios Classification There are two subtypes of Bartter syndrome: classic: presents in early childhood with polyuria, polydipsia [radiopaedia.org]

  At the age of 3 years, she developed moderate polyuria and polydipsia, with mild failure to thrive. [scielo.br]

  After birth, the infant is seen to urinate and drink excessively ( polyuria, and polydipsia, respectively). Life-threatening dehydration may result if the infant does not receive adequate fluids. [en.wikipedia.org]

• Constipation

• Polyuria

  Prenatal manifestations, mainly recurrent polyhydramnios because of fetal polyuria, lead to premature delivery. After birth, polyuria leads to life-threatening dehydration. Prenatal genetic diagnosis needs an index case. [scinapse.io]

  Polyuria of type 3 ABS may be less severe than in other types of ABS. [casereports.bmj.com]

  Hydram-nios is due to fetal polyuria. The continued polyuria in postnatal life leads to dehydration and renal salt wasting and contributes to growth retardation. Hypercalciuria may lead to early-onset nephrocalcinosis. [sjkdt.org]

  He developed polyuria, hyponatremia, and hypokalemia at 15 mo, and was diagnosed with suspected Antenatal BS and started on NaCl and KCl supplementation. He was also found to be hypercalcemic at that time. [endocrine.org]

  Appropriate fluid and electrolyte support was given to the patient to prevent hyponatremia, hypochloremia, hypokalemia, renal failure, and further weight loss. [indianjnephrol.org]

  Investigations revealed hypochloremic, hypokalemic metabolic alkalosis with hyponatremia (serum sodium 106 mEq/L, potas-sium 2 mEq/L, chloride 65 mEq/L, bicarbonate 29.6 mmol/L, and pH 7.568). [sjkdt.org]

• Calcium Increased

  Although treated, hypokalemia persisted almost universally but was less pronounced than at diagnosis, whereas the amount of urinary calcium excretion dropped to normal limits in most cases: at the last follow-up, one patient showed a urinary calcium increase [journals.plos.org]

Sodium chloride and potassium requirements were up to 35 and 4 meq/kg/day during treatment, respectively. [indianjnephrol.org]

Diagnosis - Bartter syndrome- antenatal- type 1 Prognosis - Bartter syndrome- antenatal- type 1 Treatment - Bartter syndrome- antenatal- type 1 Once ABS is confirmed, mother should be treated antenatally at the earliest with indomethacin (1 mg/kg/day) [checkorphan.org]

Long-term prognosis is guarded. Lack of satisfactory control may lead to morbidity, growth failure, and renal insufficiency [2, 18, 23]. 8. Prognosis Untreated ABS patients may succumb to dehydration, dyselectrolytemia, and intercurrent infections. [ncbi.nlm.nih.gov]

Thus, Bartter's syndrome in the fetus though rare must be considered as an etiologic factor of hydramnios in pregnancy especially if seen in a recurrent manner. [medknow.tv]

Etiology Type 1 Bartter syndrome is caused by mutations in the SLC12A1 (15q15-q21) encoding sodium-potassium-chloride co-transporter protein, NKCC2 whereas Type 2 Bartter syndrome is caused by mutations in KCNJ1 (11q24) encoding renal outer medullary [orpha.net]
