Trial summary

Primary ciliary dyskinesia is an autosomal recessive disorder characterized by abnormal ciliary movement and disrupted mucociliary clearance. In uncleaned airways, microorganisms and respiratory irritants cause inflammation and infection. Read more about this study

About this study

Official title: Comparison of Respiratory Muscle Strength, Exercise Capacity and Physical Activity Levels in Children With Primary Ciliary Dyskinesia and Healthy Controls

Primary ciliary dyskinesia is an autosomal recessive disorder characterized by abnormal ciliary movement and disrupted mucociliary clearance. In uncleaned airways, microorganisms and respiratory irritants cause inflammation and infection. Permanent rhinitis and chronic sputum cough are typical features in primary ciliary dyskinesia patients. Primary ciliary dyskinesia is a disease that threatens lung function from pre-school age. One of the main causes of respiratory muscle weakness in chronic lung diseases diseases is worsening of lung function. Such a weakness causes alveolar hypoventilation, microatelectasis, reduction of the cough strength .The cough strength is important for airway cleaning.

Exercise capacity is affected in chronic lung diseases. Assessment of exercise capacity in chronic lung diseases is prognostically important. Reduced exercise capacity and pulmonary function in PCD cause decrease in physical activity level. PCD patients have low quality of life and early recognition has been found to affect the quality of life positively. Children with chronic illness have higher level of depression than healthy children.

In literature, no study investigated respiratory muscle strength, exercise capacity and physical activity PCD patients. Therefore, the investigators aimed to compare aforementioned outcomes in PCD patients and healthy controls.

Read the detailed description

According to sample size calculation 26 diagnosed primary ciliary dyskinesia patients and 26 healthy individuals will be included. Respiratory muscle strength, anaerobic and aerobic exercise capacity, physical activity, pulmonary functions, peripheral muscle strength, cough strength, respiratory muscle endurance, activity dyspnea perception, quality of life and depression will be evaluated. Primary outcome measurements are respiratory muscle strength, exercise capacity, physical activity; secondary outcomes are pulmonary functions, peripheral muscle strength, cough strength, respiratory muscle endurance, activity dyspnea perception, quality of life and depression.

What is being measured

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

  1. Respiratory muscle strength

    Evaluated using mouth pressure device

    Measured: first day

  2. Functional exercise capacity

    Evaluated using 6-minute walking test

    Measured: first day

  3. Anaerobic exercise capacity

    Evaluated using 3-minute step test

    Measured: first day

  4. Physical activity

    Evaluated using a metabolic holter

    Measured: first day

Secondary outcomes (8)
  1. Pulmonary functions

    Evaluated using spirometer

    Measured: first day

  2. Muscle strength

    Evaluated using hand-held dynamometer for peripheral muscles (shoulder abduction, elbow flexion, knee extension, hand grip strength)

    Measured: second day

  3. Cough strength

    Evaluated using PEFmeter

    Measured: second day

  4. Respiratory muscle endurance

    Evaluated using respiratory muscle trainer (POWERbreathe)

    Measured: second day]

  5. Activity dyspnea

    Evaluated using Modified Borg Scale (0-10 scores, higher values represent a worse outcome)

    Measured: first day

  6. Generic Quality of life

    Cystic Fibrosis Questionnaire Revised (CFQ-R) Turkish version (Scores range from 0 to 100, with higher scores indicating better health. 9 Quality of life domains:

    Physical, role/school, vitality, emotion, social, body image, eating, treatment burden, health perceptions.3 symptom scales:

    Weight, respiratory, and digestion.Number of items in CFQ-R CFQ-R Teen/Adult: 50. CFQ-R Parent: 44. CFQ-R Child: 35.)

    Measured: second day

  7. Disease- specific quality of life

    Health-related quality-of-life questionnaires-Primary Ciliary Dyskinesia ( PCD-QOL) Turkish version ( PCD-QOL questionnaire developed different domains for different age groups: pediatric, adolescent, and adult patients as well as parents. These domains mainly evaluate physical, emotional, and social aspects of PCD related to QOL. Moreover, there are different domains for various symptoms at different age groups. The total numbers of items in the questionnaires are 37 in the questionnaire for children, 43 in the one for adolescents, 49 in the one for adults, 41 in the parents' questionnaire.

    Measured: second day

  8. Depression

    Children's Depression Inventory Turkish Version (Children's Depression Inventory is a 27-item, self-rated, symptom-oriented scale.

    Measured: second day

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Ciliary Dyskinesia, run by Gazi University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Respiratory muscle strength (time frame: first day). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03370029, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
