title: Intermittent oral desmopressin therapy for monosymptomatic primary nocturnal enuresis.
abstract: OBJECTIVE
  In a prospective study we evaluate the efficacy of intermittent desmopressin (DDAVP) every other day for patients with nocturnal enuresis relapse who need additional therapy.
  
  
  METHODS
  Between January 2000 and August 2001, 71 boys and 52 girls 6 to 22 years old (mean age 12.5) were treated with 0.2 mg DDAVP daily for monosymptomatic nocturnal enuresis. After an initial 2 weeks of dose titration the nonresponders were given 0.4 mg DDAVP daily. Those who did not respond to this dose were excluded from study. The remaining patients took desmopressin for 3 months. Patients with persistent enuresis after 3 months of treatment were given intermittent 0.2 or 0.4 mg DDAVP every other day. Followup was performed 6 weeks later.
  
  
  RESULTS
  Of 123 patients 92 completed the study. Mean followup after beginning intermittent DDAVP therapy was 9.2 months (range 6 to 18). Of the 92 patients 45 responded to the 0.2 mg daily dose (group 1) and continued treatment for at least 3 months, while the dose was titrated to 0.4 mg for the remaining 47 (group 2). There were 23 patients who did not respond to 0.4 mg DDAVP and they were excluded from the study. After cessation of the drug 21 group 1 patients (46.6%) and 13 group 2 patients (54%) still had enuresis, and they were placed on intermittent therapy. After 6 weeks 15 of these 34 patients had complete and 13 of the remaining 19 had partial response, while the 6 nonresponders continued on daily DDAVP. Overall the complete and partial response rate of intermittent treatment was 20 of 21 group 1 patients (95%) and 8 of 13 group 2 (61.5%).
  
  
  CONCLUSIONS
  For some enuretic patients with relapse after cessation of initial 3-month therapy, intermittent DDAVP may be an effective alternative long-term treatment.
