Received Oct 25; Accepted Aug Excluiu-se nefrocalcinose, por meio de tomografia computadorizada helicoidal. J Clin Endocrinol Metab. As pointed out by Brum et al. National Center for Biotechnology InformationU.

Leucocytes and platelet counts were normal and the bone marrow biopsy was mildly hypocellular causaw for an erythroid hyperplasia. Although the erytrocitosis might have been secondary eirtrocitosis polyuria, the 24 hours urine volume of the current patient was not so high to cause volume contraction.

Repetitive hemodilution writrocitosis chronic obstructive pulmonary disease and pulmonary hypertension: The absence of metabolic alkalosis in the current patient although unexpected, has already been described in cases of BS type I or II 78 or even in other adult onset presentations of BS type IV.

We report an unusual case of late onset presentation of Bartter syndrome IV and mild phenotype in a 20 years-old man who had hypokalemia, deafness, secondary hyperparathyroidism and erythrocytosis. The patient had other deaf brother and a stone-forming sister.

Javier Leonardo Galindo http: Polycythaemia due to hypoxaemia: 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. J Am Soc Nephrol.

Phenotypic variability in Bartter syndrome type I.

Adult presentation of Bartter syndrome type IV with erythrocytosis

Serum 25OH – vitamin D Erythropoietin EPO was also within normal limits Effects of erythrapheresis on pulmonary haemodynamics and oxygen transport in patients with secondary polycythaemia and cor pulmonale. Variables were described using an additional categorization by hematocrit levels and an adjustment in a multivariate model through logistic regression. Bartter syndrome comprises a group of rare autosomal-recessive salt-losing disorders with distinct eritroctiosis, but one unifying pathophysiology consisting of severe reductions of sodium reabsorption efitrocitosis 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.

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. Increased levels of serum PTH could have been ascribed to mild hypocalcemia but not to hypomagnesemia, which was not observed in the present case.

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.

La frecuencia de anemia fue de 7. 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. Thus, determining the implications of erythrocyte parameters might contribute to define the usefulness of phlebotomy or red blood cells transfusion in these patients.

To establish a possible relationship between the different hematocrit levels with a day prognosis in patients admitted with exacerbated chronic lung disease and hypoxemia.

These findings are in agreement with Vaisbich et al.

Predictors of outcomes in COPD exacerbation cases presenting to the emergency department. Seus pais notaram sua hipoacusia no segundo ano de vida. The etiology of erythrocytosis was investigated. Therefore, distinct mutations of BSND cause phenotypes of varying severity.

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.

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

Haemoglobin level and its clinical erittrocitosis in a cohort of patients with COPD. A computed helical tomography excluded nephrocalcinosis. Scopus is a bibliographic database publishing summaries and references concerning articles from scientific journals. Hemoglobin levels above anemia thresholds are maximally predictive for long-term survival in COPD with chronic respiratory failure.
