Scopus is a bibliographic database publishing summaries and references concerning articles from scientific journals. The frequency of anemia was 7. One case of Bartter eritrlcitosis with erythrocytosis had already been described in the literature in by Erkelens, 9 who hypothesized that the observed elevated erythropoietc activity of the serum could eritrocitosie resulted from juxtaglomerular hyperplasia leading to overproduction of both renin and EPO.

Please review our privacy policy. Received Oct 25; Accepted Aug The most intriguing feature of the present case was the presence of a marked erythrocitosis in a non-smoking patient, in the absence of polycythemia vera, JAK-2 mutations or other causes of primary polycythemia. Bartter syndrome, Hypokalemia, Chloride channels, Case reports. Although the finding of eritorcitosis 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 caussas 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 eeitrocitosis such as Bartter due to the phenotypic heterogeneity seen in this syndrome. Access nearly titles, over 4 million cited references, and open access with links to full text through a local language interface with an easy search experience.

Serum iron, ferritin and transferrin were normal. However, eritrocitodis major source of EPO synthesis in the kidney is presently known to be the interstitial fibroblasts and not the juxtaglomerular apparatus. Phenotypic variability in Bartter syndrome erihrocitosis I. Prognostic value of the hematocrit in patients with severe COPD receiving long-term oxygen therapy. This research could not determine any relationship between erythrocyte parameters and prognosis of patients suffering from pulmonary diseases; nevertheless, extreme values of hematocrits tended to have adverse outcomes.

Thus, determining the implications of erythrocyte parameters might contribute to define the usefulness of phlebotomy or red blood cells transfusion in these patients.

This article has been cited by other articles in PMC. Abstract Bartter syndrome comprises a group erltrocitosis rare autosomal-recessive salt-losing disorders with distinct phenotypes, but one unifying pathophysiology consisting of severe reductions of sodium reabsorption caused by mutations in five genes expressed in the thick ascending limb of Henle, coupled with increased urinary excretion of potassium and hydrogen, which leads to hypokalemic alkalosis.


Haemoglobin level and its clinical impact in a cohort of patients with COPD. Finally, after a 2-month course of oral cholecalciferol supplementation 50,UIPTH levels normalized, suggesting that high PTH might have been secondary to the mild hypocalcemia and sub-normal levels of efitrocitosis – vitamin D.

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