The effect of exogenous 3':5'-adenosine monophosphate on urinary output in children with vasopressin-resistant diabetes insipidus

Abstract

The administration of c-AMP and DB c-AMP to six children with NDI has failed to yield an antidiuretic effect. From the present study it may be concluded that, at the doses used, neither c-AMP nor its dibutyryl derivative can mimic the action of ADH in NDI as they do in normal subjects. On the contrary, DB c-AMP increased urine volume and Cosm in a very marked way, without changing the creatinine excretion.
