A vasopressin analogue in treatment of diabetes insipidus. Six children, 3 adolescents, and 3 adults with vasopressin-sensitive diabetes insipidus were treated with a vasopressin analogue, DDAVP (1-deamino-8-D-arginine vasopressin), at a daily dose ranging from 5 to 20 ,ug administered twice a day intranasally. The period of follow-up of these patients has been from 3 months to 1 year.DDAVP was effective in maintaining normal diuresis and normal urine concentration during both day and night. No local or vasopressor side effects were observed. Compared to other antidiuretic drugs, such as nasal pitressin powder, lysine-vasopressin nasal spray, or pitressin tannate injections, used previously by the patients, DDAVP proved to be superior in the control of the diabetes insipidus and in the subjective feeling of the patients.It is concluded that DDAVP is the drug of choice in the treatment of vasopressinsensitive diabetes insipidus.Good control of diabetes insipidus is especially important in children since, in addition to the interference with normal school attendance, social activities, and night rest, normal growth is disturbed by the imbalance in water and electrolyte metabolism. Up to now none of the drugs employed have proved satisfactory and some have caused troublesome side effects.We report our experience with a new antidiuretic preparation, DDAVP (1-deamino-8-D-arginine vasopressin), a synthetic analogue of the natural human antidiuretic hormone. Its features are a lack of pressor activity and side effects, together with a prolonged antidiuretic action.
Subjects and methodsTwelve patients (7 females and 5 males) with diabetes insipidus were included in this study. 9 were children or adolescents (5 years 9 months to 18 years) and 3 were adults. 2 of the adult patients (aged 224 and 24 years) have been under our care since childhood, while the third, a 34-year-old patient with a pituitary tumour, was under the care of the Department of Neurosurgery.The pertinent clinical data are summarized in Table I.
