Mortality and mortality-related factors after hospitalization for acute exacerbation of COPD. Variables were described using an additional categorization by hematocrit levels and an adjustment in a multivariate model through logistic regression.

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. The effects of therapeutic decrease in packed cell volume on the responses to exercise of patients eritrocitois polycythaemia secondary to lung disease. J Am Soc Nephrol.

Besides, EPO levels showed to be within normal range cauass the present case. Serum 25OH – vitamin D One case of Bartter associated 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 have resulted from juxtaglomerular hyperplasia leading to overproduction of both renin and EPO.

Hemoglobin levels above anemia thresholds are eritrocitosiz predictive for long-term survival in COPD with chronic respiratory failure. Esses achados corroboram os de Vaisbich et al.

Therefore, the exact cause of erytrocytosis remains unclear. Even though exacerbations are the main cause of emergency consultation in patients suffering from lung diseases, erythrocyte parameters are not assessed in their prognosis. These findings are eritrocitoiss agreement with Vaisbich et al. 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 five genes expressed in the thick ascending limb of Henle, coupled with increased urinary causaas of potassium and hydrogen, which leads to eritrocitossi alkalosis.

Scopus Scopus is a bibliographic database publishing summaries and references concerning articles from scientific journals. Hyperreninemia, lysozymuria, and erythrocytosis in Fanconi syndrome with medullary cystic kidney.

Thus, determining the implications of erythrocyte parameters might contribute to define the usefulness of phlebotomy or red blood cells transfusion in these patients. Increased levels of serum PTH could have been ascribed to mild hypocalcemia but not erigrocitosis hypomagnesemia, which was not observed in the present case.

The patient had other deaf brother and a stone-forming sister. 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.

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 25OH – vitamin D. Although the erytrocitosis might have been secondary to polyuria, the 24 hours urine volume of the current patient was not so high to cause volume contraction.
