Validation of New Diagnostic Indices to Simplify Hyponatremia Therapy Assessment in Patients on Thiazide Diuretics
Sponsor: University Hospital, Basel, Switzerland
Summary
This study is looking at two new parameters, aSID and ChU, to see if these can help physicians to distinguish between different causes of low sodium levels (hyponatremia) in Patients taking a medicament against high blood pressure (thiazide). Researchers also want to see if using these new parameters to decide on treatment works just as well, or better, than the current standard treatments.

aSID/ChU Guided Therapy
Stopping of thiazide therapy. Measure aSID: * aSID between 39 and 42 mmol/l : measure ChU * ChU lower than 15mmol/l : fluid administration (0.9% NaCl infusion, 250-500 ml over 2 hours followed by 10-20 ml/kg/24h) * ChU higher than 14.9 mmol/l : drinking restriction (of at least 50% of usual drinking volume) * aSID higher than 42 mmol/l : fuid administration (fluid administration (0.9% NaCl infusion, 250-500 ml over 2 hours followed by 10-20 ml/kg/24h) * aSID lower than 39 mmol/l : drinking restriction (of at least 50% of usual drinking volume) The aSID/ChU guided therapy will take place for a minimum of 1- and a maximum of 3 days after enrolment. Treatment and adherence to the treatment will be assessed and re-evaluated at least daily for 3 days or till discharge or sodium normalization.
