METHOD: Patients with brain injury admitted to the intensive care unit were included and had their BNP, aldosterone and vasopressin levels dosed on day 7. RESULTS: Twenty six adult patients were included in the study. Nine (34.6%) had hyponatremia and presented with a negative water balance and higher values of urinary sodium, serum potassium and diuresis than patients with normonatremia. The serum levels of BNP, aldosterone, and vasopressin were normal and no relation was observed between plasma sodium and BNP, aldosterone or vasopressin. CONCLUSION: The most likely cause of hyponatremia was CSWS and there was no correlation between BNP, aldosterone and vasopressin with serum sodium level.<\/jats:p>","DOI":"10.1590\/s0004-282x2009000600014","type":"journal-article","created":{"date-parts":[[2010,1,7]],"date-time":"2010-01-07T15:47:28Z","timestamp":1262879248000},"page":"1037-1044","source":"Crossref","is-referenced-by-count":14,"title":["Hyponatremia and brain injury: absence of alterations of serum brain natriuretic peptide and vasopressin"],"prefix":"10.1590","volume":"67","author":[{"given":"Karina Nascimento","family":"Costa","sequence":"first","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helen Mayumi","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; Escola Superior em Ci\u00eancias da Sa\u00fade, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonardo Rodrigues da","family":"Cruz","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; Escola Superior em Ci\u00eancias da Sa\u00fade, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas Sampaio Valente Fernandes de","family":"Miranda","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; Escola Superior em Ci\u00eancias da Sa\u00fade, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rubens Carneiro dos","family":"Santos-Neto","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; Escola Superior em Ci\u00eancias da Sa\u00fade, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susyanne de Lavor","family":"Cosme","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; Escola Superior em Ci\u00eancias da Sa\u00fade, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Augusto","family":"Casulari","sequence":"additional","affiliation":[{"name":"Hospital de Base do Distrito Federal, Brazil; University of Bras\u00edlia, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"11","article-title":"Differential diagnosis and treatment of hyponatremia following pituitary surgery","volume":"48","author":"Casulari LA","year":"2004","journal-title":"J Neurosurg Sci","ISSN":"http:\/\/id.crossref.org\/issn\/0390-5616","issn-type":"print"},{"key":"ref2","first-page":"57","article-title":"salt-wasting syndrome associated with cerebral disease","volume":"63","author":"Peters JP","year":"1950","journal-title":"Trans Assoc Am Physicians","ISSN":"http:\/\/id.crossref.org\/issn\/0066-9458","issn-type":"print"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"529","DOI":"10.1016\/0002-9343(57)90224-3","article-title":"A syndrome of renal sodium loss and hyponatremia probably resulting from inappropriate secretion of antidiuretic hormone","volume":"23","author":"Schwartz WB","year":"1957","journal-title":"Am J Med","ISSN":"http:\/\/id.crossref.org\/issn\/0002-9343","issn-type":"print"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1016\/S0749-0704(05)70155-X","article-title":"Endocrine and metabolic dysfunction syndromes in the critically ill.
