The proper management of hyponatremia requires the consideration of several aspects, such as the duration and severity of the disorder, the presence or absence of symptoms and etiological diagnosis.

Pathophysiology of edema formation. Since neurological damage resulting from pontine myelinolysis is frequently irreversible, the best alternative is prevention. It is important to focus on the identification and correction of the cause: Eur J Haematol ; In hospitalized patients, one strategy is to use hypertonic saline; the excretion of the solute overload will cause the obligatory excretion of distirbio large amount of free water.

Without ADH, collecting ducts are impermeable to water, resulting in the excretion of a great quantity of dilute urine and elimination of excess water Table 2. We divided the abnormal results into two groups: The authors emphasize that serum potassium depletion may contribute to hyponatremia, due to sodium shift from gidroeletrolitico ECF to the ICF. A few exceptions should be considered.

The correlation of an altered macroscopic aspect of the CSF and neurocryptococosis, of septic syndrome and a diagnosis of a syndrome considered sufficient hdroeletrolitico interesting. We suggest that a CSF analysis, besides being obviously indicated in the suspicion of meningitis, also be considered if, after an initial clinical and laboratorial evaluation, there is no evident explanation for acute consciousness compromise in HIV-positive patients.


Anesth Analg ; It was found a relatively low frequency of this diagnosis problably because of the usually sub-acute or chronic rather than acute presentation of TME. Severe hyponatremia without severe hypoosmolality following transurethral resection of the prostate TURP in end-stage renal disease.

Cerebrospinal fluid syndromes in HIV-positive patients with acute consciousness compromise

However, in AIDS patients, the viral syndrome may reflect a variety of infections commonly found in HIV-positive patients, mainly toxoplasmosis, as is shown in the correlation of the viral syndrome and the positivity of Hematoxo. Syndrome of inappropriate secretion of antidiuretic hormone SIADH after treatment with cyclophosphamide, alpha-interferon and betamethasone in a patient with multiple myeloma.

In this situation, use of AZT may diminish the pleocytosis and the protein alterations, confirming that the alterations were induced by the own viruses 5. Therapy should be focused on the correction of hypovolemia because after this, sodium concentration is expected to normalize “automatically”.

Some laboratory studies are very useful in the differential diagnosis of hyponatremia.

Successful treatment of adult cerebral salt wasting with fludrocortisone. Nephrol Ther ; 3 Suppl 2: A sixty-year-old white female, recently diagnosed with glioblastoma multiforme and treated with temozolomide, presented to the oncologist’s office complaining of drowsiness.


Greenberg A, Verbalis JG. By reversing the hypovolemia, normal saline removes the baroreceptor stimulus for ADH secretion. Because it is a fraction, the result may be altered by changes in the numerator total body sodium or in the denominator plasma water in which the sodium is dissolved. Arquivos de Neuropsiquiatria Mutations in the V2 vasopressin receptor gene The clinical picture is identical to that of SIADH euvolemic hypotonic hyponatremia with concentrated urine but ADH serum levels are undetectable.


Am J Med ; The correlation between positivity of hematoxo and the viral syndrome reflect that, not infrequently, lymphocytic pleocytosis is found in toxoplasmosis.

Severe hyponatremia and pulmonary edema during hysteroscopy]. This is classically described in hyperproteinemias, for example, multiple myeloma and severe dyslipidemia for example, hypertriglyceridemiawhen the aqueous plasma fraction is reduced due to the excess of proteins or lipids.

With potassium replacement, there is the inverse movement of sodium from ICF to ECF, which accelerates the correction of hyponatremia.

The CSF analysis showed abnormal results in hidroeletroliitco patients, as is shown in Table 1.

Evaluation of the patient with hyponatremia. The syndrome of inappropriate antidiuresis. With a similar methodology, we found Therefore, the sodium deficit would be: Ann Intern Med ; disturibo Due to their subjacent disease, these patients are susceptible to wide range of etiological possibilities, like opportunistic infections and neoplasias, besides the own HIV infection.
