Urinary Aquaporine 2 in Patients With Syndrome of Inappropriate ADH-secretion Caused by Treatment With Antiepileptic Medicine
Patients treated with the antiepileptic drug Oxcarbazepine often develop syndrome of inappropriate secretion of antidiuretic hormone(SIADH)We want to test the hypothesis, that these patients have a higher reabsorption of water during the Aquaporine2 water channels,a higher concentration of Vasopressine (AVP), and a lower clearance of water.This situation will tend to normalize, when the patients are treated with fluid restriction
The purpose of the study is to determine the amount of Aquaporine2(AQP2)in the urine in patients treated with the antiepileptic drug Oxcarbazepine before and after the administration of fluid restriction
