Authors' conclusion

Skeletal health appears compromised in young people with PCD. Despite mostly normal densitometry, tibial bone microarchitecture was altered. This study positions bone health as a research priority in PCD and supports the need for larger confirmatory studies. </p>.

Study context

Population
Individuals with primary ciliary dyskinesia (PCD) or cystic fibrosis (CF) aged 12–20 years
Exposure
PCD vs healthy controls and CF
  • PCDn = 15
  • CFn = 45
Outcome
Bone phenotype: BMD (whole body, lumbar spine) by DXA and tibial bone microarchitecture by HR-pQCT
Methodological detailsexploratory, matched healthy controls (one-to-one by pubertal stage and sex)
  • Exploratory
  • Matched healthy controls (one-to-one by pubertal stage and sex)

Main finding

As reported in the abstract

Bone phenotype in PCD vs controls
  • No differences in DXA areal bone mineral density (BMD) or high-resolution peripheral quantitative computed tomography (HR-pQCT) total volumetric BMD between PCD and controls
  • Reduced cortical thickness, area and BMD at ultra-distal tibia in PCD vs controls

Observational data: associations, not effects.

Further findings

PCD vs CF

PCD and CF did not differ; PCD bone phenotype more closely resembled pancreatic-insufficient than pancreatic-sufficient CF

Adjustment for body mass index (BMI) or lean mass

Dimensional cortical deficits largely explained by BMI or lean mass, especially in CF, but remained reduced in PCD after adjustment

Lung function and bone outcomes in PCD

Lung function did not clearly correlate with bone outcomes in PCD
