About this study

Official title: Efficacy and Safety of Vitamin D Supplementation Combined With Alarm Therapy in Treating Nocturnal Enuresis: A Prospective, Randomized Controlled Trial

This prospective, randomized, two-arm, parallel-design controlled clinical trial aims to determine whether high-dose vitamin D supplementation combined with alarm therapy improves outcomes in children with primary monosymptomatic nocturnal enuresis compared to alarm therapy alone.

Read the detailed description

Nocturnal enuresis (NE) is characterized by recurrent involuntary urination during sleep in children aged 5 years and older, persisting for over three months with at least two episodes per week. This condition, resulting from the child's inability to awaken from sleep, exhibits a prevalence rate ranging from 4.8% to 15.2%, which notably declines with age. Moreover, NE significantly impacts the psychological well-being and overall quality of life of affected individuals. The primary treatments for NE include desmopressin acetate (DDAVP) and behavioral interventions (BI). While these modalities offer therapeutic benefits, their implementation is often prolonged and fraught with challenges, including adverse drug reactions and a high rate of symptom recurrence after treatment discontinuation. These factors complicate adherence for both patients and their families.

Patients with NE are more likely to suffer from vitamin D deficiency. This study aims to determine the effect of vitamin D supplementation as an adjunctive therapy to alarm therapy in the treatment of primary monosymptomatic nocturnal enuresis(PMNE). Eligible patients aged 5-18 years with a diagnosis of NE will be randomly assigned to receive either high-dose vitamin D supplementation combined with alarm therapy or alarm therapy alone. Serum levels of 25(OH)D will be measured at baseline. Symptom severity will be assessed at baseline and follow-up, along with other sociodemographic data. This study will provide more information on the role of vitamin D supplementation in managing PMNE.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Response after interventions

    Response rate: defined as a ≥50% reduction in the number of wet nights per week

    Measured: 8 weeks

  2. Complete response after interventions

    The rate of complete response was defined as a 100% reduction in wet nights per week.

    Measured: 8 weeks

Secondary outcomes (8)
  1. Change in enuresis frequency

    Change in enuresis frequency from baseline to follow-up

    Measured: 8 weeks

  2. Change in quality of life score

    The quality of life was assessed using a scale ranging from 0 to 3, where a score of 0 indicated no impact on family, social, or academic life, a score of 1 indicated occasional impact, a score of 2 indicated significant impact, and a score of 3 indicated severe impact on family, social, or academic life.

    Measured: 8 week

  3. Change in vitamin D level

    Change in vitamin D level from baseline to follow-up

    Measured: 8 week

  4. Change in serum levels of calcium

    Change in serum levels of calcium from baseline to follow-up

    Measured: 8 weeks

  5. Global perception of improvement

    Global perception of improvement (much better; better; about the same; worse)

    Measured: 8 week

  6. Wish to receive another form of treatment?

    Wish to receive another form of treatment? (YES; No)

    Measured: 8 week

  7. Treatment adherence

    The extent to which a patient adheres to their medication schedule, including both timing and dosage, or follows the prescribed treatment regimen

    Measured: 8 week

  8. Incidence of side effects

    Type and frequency of side effects during treatment

    Measured: 8 week
