All are features of Bater syndrome EXCEPT?: (A) Hypokalaemia, (B) Metabolic Alkalosis, (C) Hypocalciuria, (D) Salt wasting
Answer is C. Bater syndrome is an autosomal recessive disorder characterized by hypokalemia and metabolic alkalosis resulting from excessive chloride, potassium and sodium wasting in the thick ascending limb of the loop of Henle. In Bater syndrome: Hypochloremic Metabolic alkalosis, hypokalemia, hyponatremia, hypercalciuria and increased urinary chloride loss are seen. Elevated urinary levels of chloride (>20-30 mEq/L) are characteristic of Bater syndrome.
