28 juillet 2026 mis à jour par: Kerim Kaan Göküstün, Izmir Democracy University

Associations Between the Status of Malnutrition and Sarcopenia in Children and Adolescents With Primary Ciliary Dyskinesia

The prevalence and causes of malnutrition and sarcopenia in children and adolescents with Primary ciliary dyskinesia (PCD) have not been sufficiently elucidated. The aim of this study is to investigate the prevalence of malnutrition and sarcopenia in children and adolescents with PCD.

Description détaillée

Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder characterized by abnormal ciliary motility and impaired mucociliary clearance. It develops as a result of mutations in genes responsible for ciliary movement. Structural or functional abnormalities of cilia lead to chronic upper and lower respiratory tract infections, fertility problems, and organ laterality defects. The prevalence of PCD ranges from 1 in 2,000 to 1 in 40,000, varying among different ethnic groups. The disease begins to negatively affect lung function from the preschool period onward. In children with PCD, respiratory function is generally characterized by mild to moderate airway obstruction. As the disease progresses, the severity of airway obstruction increases. Therefore, regular monitoring of pulmonary function is of great importance in the management of PCD. The prevalence and causes of malnutrition and sarcopenia in children and adolescents with PCD have not been sufficiently elucidated. The aim of this study is to investigate the prevalence of malnutrition and sarcopenia in children and adolescents with PCD.

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Handgrip Muscle Strength in Participants
Délai: From enrollment to the end of treatment at 1 year
Bilateral grip strength in children and adolescents with PCD will be measured in kgF using a hand dynamometer.
From enrollment to the end of treatment at 1 year

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Malnutrition risk score in Participants
Délai: From enrollment to the end of treatment at 1 year
The Nutritional Status and Growth Risk Screening Tool will be used to assess the risk of growth failure. The total score on this scale ranges from 0 to 5; a score of 0 indicates a low risk of malnutrition, a score of 1-3 indicates a moderate risk of malnutrition, and a score of 4-5 indicates a high risk of malnutrition.
From enrollment to the end of treatment at 1 year
Body Weight
Délai: From enrollment to the end of treatment at 1 year
Body weight in children and adolescents with PCD will be measured using a pediatric scale.
From enrollment to the end of treatment at 1 year
Height
Délai: From enrollment to the end of treatment at 1 year
In children and adolescents with PCD, height will be measured using a stadiometer.
From enrollment to the end of treatment at 1 year
Body Mass Index
Délai: From enrollment to the end of treatment at 1 year
For children and adolescents with PCD, the body mass index will be calculated by dividing body weight by the square of height in meters.
From enrollment to the end of treatment at 1 year
Waist circumference
Délai: From enrollment to the end of treatment at 1 year
Waist circumference in children and adolescents with PCD will be measured using a tape measure
From enrollment to the end of treatment at 1 year
Hip circumference
Délai: From enrollment to the end of treatment at 1 year
Hip circumference in children and adolescents with PCD will be measured using a tape measure
From enrollment to the end of treatment at 1 year
Waist-to-hip ratio
Délai: From enrollment to the end of treatment at 1 year
In children and adolescents with PCD, the waist-to-hip ratio will be calculated by dividing the waist circumference by the hip circumference.
From enrollment to the end of treatment at 1 year
Waist-to-Height ratio
Délai: From enrollment to the end of treatment at 1 year
In children and adolescents with PCD, the waist-to-height ratio will be calculated by dividing the waist circumference by the height.
From enrollment to the end of treatment at 1 year
Upper-middle arm circumference
Délai: From enrollment to the end of treatment at 1 year
In children and adolescents with PCD, upper arm circumference will be measured using a non-stretchable tape measure, without tightening it or leaving any slack.
