[Partial diabetes insipidus and ascitic liver cirrhosis in a patient].

The occurrence of hepatic cirrhosis with ascites and diabetes insipidus in the same patient is described. The stimulability of residual vasopressin was confirmed by water deprival and the partial vasopressin deficit by the administration of dDAVP. Water loading test referred to the possibility of suppression of residual vasopressin. Studying the specific renal functions in diets of different sodium content following the administration of dDAVP and diuretics, the diuretic without adding ADH was found to be the best therapy for these patients. Reviewing the literature the authors are taking into consideration the difficulties of differential diagnostics and the mechanisms which may explain the inhibiting effect of the liver disease on the polyuria associated with diabetes insipidus.
