Clinical Predictors of Pediatric OSAHS (PEDOSA)

December 9, 2015 updated by: Chang Gung Memorial Hospital

Clinical Predictors of Pediatric Obstructive Sleep Apnea/Hypopnea Syndrome

The purpose of this study is to develop adequate and satisfactory tools using reliable clinical and physical factors in predicting pediatric obstructive sleep apnea/hypopnea syndrome (OSAHS) and allow greater access to appropriate therapy in children.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The prevalence of OSAHS is estimated to be about 1% to 4% in children, however, it is frequently underdiagnosed because of the difficulties for evaluation.Current diagnostic approaches are based on the patient's history, clinical presentation and physical examination, endoscopy, and radiological imaging examinations, and confirmation is made by the current gold standard of full-night polysomnography (PSG). Previous studies have reported the use of a clinical history, physical examination and questionnaires for predicting pediatric OSAHS but there were lacking of adequate and satisfactory results. Despite the potential diagnostic benefits, PSG for pediatric patients are not routinely used in clinical practice. Therefore, to obtain a reliable, valid, and easily-performed diagnostic or screening tool for the clinical assessment of pediatric OSAHS is essential for the cost-effective care of these patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 18 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

children with chief complaints of snoring

Description

Inclusion Criteria:

  • children (younger than 18 years old and older than 2 years old) with symptoms of snoring and then were confirmed to having obstructive sleep apnea/hypopnea syndrome by a comprehensive polysomnography

Exclusion Criteria:

  • patients with substance abuse problems or the long-term usage of medications known to affect sleep, craniofacial abnormalities or neuromuscular disorders, Down syndrome, cerebral palsy, mucopolysaccharidoses, Prader-Willi syndrome, history of psychosis, central sleep apnea syndrome, or previous airway surgery including tonsillectomy and/or adenoidectomy were excluded from the study.

pediatric sleep apnea
The children were confirmed to have OSAHS by comprehensive polysomnography (PSG).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical predictors for apnea/hypopnea index (AHI)
Time Frame: up to 4 months
When all variables were analyzed individually with the AHI, Spearman rank correlation analysis was used to explore the relationships between clinical predictor variables and AHI.Significant variables were entered into stepwise multiple linear regression analysis to identify independent predictors for pediatric OSAHS and to develop a predictive equation for AHI values.
up to 4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Anthropometric measurements: body mass index z-score (BMI z-score)
Time Frame: up to 4 months
BMI z-score: a measure of relative weight adjusted for the child's age and gender, and calculated by dividing the difference between the measured value and the mean by the standard deviation.
up to 4 months
Anthropometric measurements: tonsil size grading
Time Frame: up to 4 months
Tonsil size grading: 0, surgically removed tonsils; 1, tonsils hidden within the pillars; 2, tonsils extending to the pillars; 3, tonsils were beyond the pillars but not to the midline; and 4, tonsils extended to the midline.
up to 4 months
Anthropometric measurements: modified Mallampati grade (aka updated Friedman's tongue position
Time Frame: up to 4 months
updated Friedman's tongue position: I: visualization of the entire uvula and tonsils/pillars.; IIa: visualization of most of the uvula, but the tonsils/pillars are absent.; IIb: visualization of the entire soft plate to the base of the uvula.; III: visualization of some of the soft palate, but the distal structures are absent.; IV: visualization of the hard palate only.
up to 4 months
Anthropometric measurements: uvular length
Time Frame: up to 4 months
uvular length in centimeter
up to 4 months
Snoring visual analogue scale (Snoring VAS)
Time Frame: up to 4 months
Snoring VAS (Units on a Scale): 0-10, 0 = "no snoring noise" and 10 = "the loudest sound imaginable
up to 4 months
Apnea/hypopnea index (AHI)
Time Frame: up to 4 months
AHI: total number of apneas and hypopneas per hour of electroencephalographic sleep.
up to 4 months

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
