CF could be presented as PBS, mainly in patients younger than 2 years. [elsevier.es]

Although there is significant variability in the presentation of some subtypes of Bartter syndrome, there is still a strong genotype-phenotype correlation in some mutations, like the one we present here. [scielo.mec.pt]

Out of 11 cases, 6 (54.54%) patients in PBS group presented with features consistent with PBS leading to CF diagnosis labeled as “early presenters”. [cysticfibrosisjournal.com]

Among BS cases, antenatal/neonatal BS (ABS) usually shows distinct polyhydramnios prenatally and presents features of BS in the early neonatal period. [casereports.bmj.com]

In some individuals, hypercalciuria is also present. Mutations in several genes have been associated with the disorder. [journalrip.com]

• Disability

  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]

  We may also use ultrasound imaging to look for calcium deposits in your child's kidneys. It is very unusual for Bartter syndrome to cause severe kidney failure, but in those rare cases, we treat the kidney failure as needed. [childrenscolorado.org]

  Kidney function is also normal if the disease is treated,[4] but occasionally patients proceed to end-stage kidney failure. [en.wikipedia.org]

  Medicine may be needed that blocks the kidney's ability to get rid of potassium. High doses of nonsteroidal anti-inflammatory drugs (NSAIDs) may also be used. Infants who have severe growth failure may grow normally with treatment. [medlineplus.gov]

Affected individuals may be encouraged to undergo a cardiac workup to screen for risk factors for cardiac arrhythmias. Individuals with a prolonged QT interval should avoid drugs that prolong the QT interval. [rarediseases.org]

The initial treatment of the patient with oral potassium was not satisfactory. Treatment with acetylsalicylic acid was associated with some effect, and an allergic reaction led withdrawal of treatment. [peertechzpublications.com]

Management and treatment Especially in the perinatal period, treatment includes vigorous salt and fluid replacement therapy. Non-steroidal anti-inflammatory drugs (e.g. indomethacin or celecoxib) are the second mainstay of therapy. [orpha.net]

Parents were counseled regarding the prognosis, and the need for parental and prenatal testing. The baby was discharged on day 33 at a weight of 1.42 kg. At 3 ½ mo-of-life, the child was weighing 2.5 kg. BERA confirmed profound hearing loss. [link.springer.com]

Prognosis The perinatal course is critical because of the complications of severe prematurity. Life expectancy may be reduced in severe cases and chronic renal failure may develop in a subset of children. [orpha.net]
