Insights
Combination therapy of desmopressin with low-dose imipramine effectively treats primary nocturnal enuresis in children unresponsive to desmopressin alone. This approach significantly improves recovery rates for bedwetting.
Area of Science:
- Pediatrics
- Urology
- Pharmacology
Background:
- Nocturnal enuresis significantly impacts children's quality of life.
- Primary nocturnal enuresis often requires effective treatment strategies.
- Desmopressin is a common treatment, but some patients do not respond adequately.
Purpose of the Study:
- To evaluate the efficacy of combining low-dose imipramine with desmopressin for treating primary nocturnal enuresis.
- To assess this combination therapy in children who are non-responders to desmopressin monotherapy.
Main Methods:
- A randomized clinical trial involving 40 children (ages 5-12) with primary nocturnal enuresis.
- Intervention group received desmopressin plus 5 mg imipramine; control group received desmopressin alone.
- Patients were monitored weekly for one month, recording the number of wet nights.
Main Results:
- The combination therapy group showed a significantly higher recovery rate (83.3%) compared to the desmopressin-only group (29.4%).
- 18 out of 20 patients in the intervention group experienced improved enuresis after one month.
- No significant differences in age or gender were observed between groups.
Conclusions:
- Low-dose imipramine combined with desmopressin is a well-tolerated and effective short-term treatment for primary nocturnal enuresis.
- This combination therapy offers a valuable option for desmopressin non-responders.
- The findings support the use of combination therapy when monotherapy is insufficient.
Introduction:
Nocturnal enuresis is a condition, which can affectthe quality of life in children. The present study was designed toinvestigate the efficacy of low-dose imipramine combined withdesmopressin on treatment of patients with primary nocturnalenuresis who were defined as desmopressin non-responders.
Methods:
A randomized clinical trial was carried out on patientswith primary nocturnal enuresis. Forty children with enuresisranging from 5 to 12 years old were randomly divided into theintervention (n = 20) and control groups (n = 20). The subjects inthe intervention group were treated with desmopressin combinedwith 5 mg imipramine at bedtime, and those in the control groupwere given desmopressin alone. The patients were followed upweekly for one month. The number of wet nights was recorded.
Results:
Two individuals in the intervention and three individualsin the control group were excluded from the study. Our findingsindicated that the age and gender showed no significant difference.Furthermore, a significant better recovery in the enuresis wasobserved in 18 of 20 patients who were treated with combinationtherapy after 1 month (P < .05). In addition, the frequency ofrecovery was significantly higher (83.3%) in the intervention group,compared with the control group (29.4%).
Conclusion:
The analysis showed that low-dose imipramine is welltolerated in clinical practice and may represent a good short-termtreatment option in combination therapy where desmopressinalone is not efficient enough.
