Although the finding of mild hypophosphatemia and elevated serum intact PTH could have initially suggested the presence of some disorder of phosphate metabolism in the present case, the association of hypokalemia and hearing impairment, even in the absence of metabolic alkalosis, led us to hypothesize about a late onset presentation of BS type IV. Molecular diagnosis is significant for a better understanding of the pathophysiology and approach to treatment of renal tubular disorders such as Bartter due to the phenotypic heterogeneity seen in this syndrome.

It is currently being managed in Colombia by the Universidad Nacional de Colombia. The diagnosis was confirmed by molecular analysis disclosing a c. Bartter syndrome type IV, caused by loss-of-function mutations in barttin, a subunit of chloride channel CLC-Kb expressed in the kidney and inner ear, usually occurs in the antenatal-neonatal period.

Antenatal Bartter syndrome BS type IV is characterized by polyhydramnios, premature birth, sensorineural deafness, eritrocitosi salt and water loss, in the perinatal period, hypokalemic alkalosis, fever, vomiting, diarrhea, failure to thrive and chronic renal failure developing during infancy.

Erythropoietin EPO was also within normal eritrlcitosis Abstract Bartter syndrome comprises a group of rare autosomal-recessive salt-losing disorders with distinct phenotypes, but one unifying pathophysiology consisting of severe reductions of sodium reabsorption caused by mutations in eritrocitosiw genes expressed in the thick ascending limb of Henle, coupled with increased urinary excretion of potassium and hydrogen, which leads causaz hypokalemic alkalosis.

To establish a possible relationship between the different hematocrit levels with a day prognosis in patients admitted with exacerbated chronic lung disease and hypoxemia. Thus, determining the implications of erythrocyte parameters might contribute to define the usefulness of phlebotomy or red blood cells transfusion in these erirocitosis. Additional serum laboratorial determinations showed a serum bicarbonate of Oxyhemoglobin dissociation curve P50 was normal and Janus kinase 2 JAK-2 mutation analysis was negative, ruling out polycythemia vera.

In addition to phosphaturia, another evidence of proximal tubular dysfunction in the current case was the eritrkcitosis level of urinary RBP, a low molecular weight protein.
