Overview
Natural History
- Bartter Syndrome usually occurs in childhood. Patient presents with the history of:
- Constipation
- Growth failure. The rate of weight gain is much lower than that of other children of similar age and gender.
- Increased urinary frequency. The patient needs to urinate more often than usual.
- Low blood pressure
- Kidney stones
- Muscle cramping and weakness[1]
Complications
Kidney failure is a possible complication.
- Bartter syndrome type I and type II are salt-wasting renal tubular disorders that are clinically characterized by polyhydramnios leading to premature delivery, marked polyuria, and a tendency towards nephrocalcinosis.[2]
- Gallstones might represent a new complication of antenatal Bartter syndrome.[3]
- Hypokalemia in Bartter syndrome can be exacerbated by electrolytes and fluid losses. Diarrhea, vomiting, alcohol abuse, cocaine, or other drugs result in electrolyte and fluid loss. Severe hypokalemia can lead to rhabdomyolysis, prolonged QT interval, life-threatening arrhythmia, syncope, and sudden death.[4][5]
Prognosis
- The limited prognostic information available suggests that early diagnosis and appropriate treatment of infants and young children with classic Bartter Syndrome (type 3) may improve growth and perhaps neuro-intellectual development. On the other hand, sustained hypokalemia and hyperreninemia can cause progressive tubulointerstitial nephritis, resulting in end-stage renal disease (Kidney failure). With the early treatment of the electrolyte imbalances, the prognosis for patients with Classic Bartter Syndrome is good.
- Patients with Bartter syndrome type I and II tend to present a satisfactory prognosis after a median follow-up of more than 10 years.[3]
