Summary
This summary is machine-generated.Young individuals with primary ciliary dyskinesia (PCD) show compromised bone health, specifically altered tibial bone microarchitecture, despite normal bone mineral density. This highlights bone health as a research priority in PCD.
Area Of Science
- Orthopedics
- Pediatrics
- Pulmonology
Background
- Bone health screening is standard in cystic fibrosis (CF).
- Bone quality in primary ciliary dyskinesia (PCD) is largely uncharacterized.
- This study investigates the bone phenotype in PCD.
Purpose Of The Study
- To evaluate the bone phenotype in young individuals with PCD.
- To compare bone health in PCD to healthy controls and individuals with CF.
- To explore associations between bone health, BMI, lean mass, and lung function in PCD.
Main Methods
- Cross-sectional study of 15 individuals with PCD and 45 with CF (aged 12-20).
- Assessed bone mineral density (BMD) via DXA and tibial bone microarchitecture via HR-pQCT.
- Compared measures to age- and sex-matched healthy controls.
Main Results
- No significant differences in BMD between PCD and controls.
- HR-pQCT revealed reduced tibial cortical thickness, area, and BMD in PCD compared to controls.
- PCD bone phenotype resembled pancreatic-insufficient CF; cortical deficits in PCD persisted after adjusting for BMI/lean mass.
Conclusions
- Skeletal health is compromised in young people with PCD.
- Altered tibial bone microarchitecture suggests intrinsic disease-related changes.
- Bone health is a research priority in PCD, requiring larger studies.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:
Chronic Inflammation
• Inhalation of Irritants: Inhaling irritants, especially cigarette smoke, are primary causes of inflammation in COPD. Other irritants can include...
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.
Medical History
• Symptom Review: Chronic symptoms such as persistent cough, sputum production, shortness of breath (dyspnea), and episodes of exacerbation are...
