[Use of demeclotetracycline in the treatment of hyponatremia in cirrhotic ascitis].

The activity of demeclotetracyclin, and ADH antagonist, is studied in 11 ethylic patients with cirrhosis of the liver, under a large hydric diet (1500 cm3). The prescription of the cyclin (600 mg daily) is always determined by a fall of the urinary osmolarity (-36%) and by a dramatic improvement of the free water clearance (+ 60%); consecutively, we observe an increase of natremia in 8 out of 9 cases. Associated with Spironolactone (200 mg daily) the anti-ADH activity persists (the free water clearance becomes positive in 5 out of 10 patients), in spite of the natriuretic activity of anti-aldosterone ; a minimal fall of the natremia is observed in only 2 cases. The indication of Demeclotetracyclin in the curative or preventive treatment of the hyponatremia of the liver cirrhosis is discussed.
