Purpose Of Review:
This review highlights recently published data on the pathophysiology, guidelines and treatment of cystic fibrosis (CF)-related bone disease.
Recent Findings:
The exact role of the cystic fibrosis transmembrane conductance regulator (CFTR), specifically the ΔF508 allele, has been investigated in F508del-CFTR homozygous mice and the F508del-CFTR mutation may contribute to CF-related bone disease by slowing new bone formation. The European Cystic Fibrosis Society has issued guidelines for bone mineral density assessment, management of low-trauma fractures and bisphosphonate therapy. A systematic review based on meta-analyses reports that oral and intravenous bisphosphonates both improve bone mineral density in CF patients, but no data are available concerning the reduction of low-trauma fractures.
Summary:
European Cystic Fibrosis Society guidelines may help physicians to improve the management of CF-related bone disease.

Cystic Fibrosis: Pathogenesis
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, but...

Bone Disorders
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...
