Clinical Trial Summary

Full ambulatory polysomnography at home performed two nights in 30 healthy children and one night in 30 children with mono-symptomatic nocturnal enuresis (15 with polyuria and 15 without polyuria). The children will be aged 7-14 years of age.

The sleep will be evaluated on sleep quality, number of periodic limb movements per hour, blood pressure and pulse, beat to beat variation by electrocardiography during sleep, respiration during sleep, nocturnal urine production, and enuresis episodes.


Description:

Purpose and perspectives:

The purpose of the study is to investigate the quality of sleep, the sleep architecture and the intra-individual variation from night to night in healthy children and children with mono-symptomatic nocturnal enuresis (MNE) using full polysomnography at home.

Hypotheses:

- There is large intra-individual night to night variation in sleep quality and architecture.

- Children with MNE have different sleep architecture than healthy children when looking at sleep quality and arousals.

- Periodic limp movements at sleep is more frequent in children with MNE than in healthy children.

Design:

The study is a case-control study.

Materials and methods:

The study will recruit 30 healthy children and 30 children with MNE (15 with polyuria and 15 without polyuria) recruited from the Childrens Incontinence Center at the Department of Pediatrics and Adolescent Medicine at Aarhus University Hospital. Children of both sexes aged between 7 and 14 years of age will be enrolled. Children and their parents will be informed about the study both verbally and in written. Written informed consent from both parents must be obtained before the children can be enrolled in the study.

The healthy children will go through two nights of full polysomnography to be able to view intra-individual changes. The children with MNE will only have to do one night of polysomnography.

Primary parameters:

- Sleep quality

- Number of periodic limb movements per hour

- Blood pressure and pulse

- Beat to beat variation by electrocardiography during sleep

- Respiration during sleep

- Nocturnal urine production

- Enuresis episodes

Outcome

Type Measure Description Time frame Safety issue
Primary Sleep efficiency Sleep efficiency will be calculated as the ratio of the total time spent asleep to the total time spent in bed One night of polysomnography.
Secondary Periodic limb movements during sleep Number of periodic limb movements per hour at sleep compared between the three groups. One night of polysomnography.
Secondary Nocturnal urine production We will compare the nocturnal urine production in millilitres in the three groups. One night of polysomnography.
Secondary Enuresis episodes We are going to look at the time of the enuresis episode and compare it to the polysomnographic findings at that time. One night of polysomnography
Secondary Respiratory events during sleep Respiration during sleep comparison between the three groups. This includes saturation, nasal air flow and movement of the stomach and chest. Together showing the number of respiratory events (apneas/hour). One night of polysomnography
Secondary Incidence of sleep disturbances Percentage of children with clinical sleep disturbances between patients and controls One night of polysomnography
Secondary Intra-individual differences in sleep efficiency from night to night in healthy controls. Sleep efficiency (in percent) will be compared between the two nights of polysomnography in the healthy controls. Two nights of polysomnography. Each evaluated after completing the two nights.
Secondary Intra-individual differences in periodic limb movements during sleep from night to night in healthy controls. Periodic limb movements during sleep will be compared between the two nights of polysomnography in the healthy controls. Two nights of polysomnography. Each evaluated after completing the two nights.
Secondary Intra-individual differences in nocturnal urine production from night to night in healthy controls. Nocturnal urine production will be compared between the two study nights in the healthy controls. Two nights of polysomnography. Each evaluated after completing the two nights.
Secondary Intra-individual differences in respiratory events from night to night in healthy controls. The number and kinds of respiratory events will be compared between the two study nights in the healthy controls. Two nights of polysomnography. Each evaluated after completing the two nights.
