Opportunistic Screening for Osteoporotic Vertebral Fractures in Patients With Diffuse Interstitial Lung Disease

Completed

• Conditions: Vertebral Fracture; Interstitial Lung Disease; Osteoporosis

• Registration Number: NCT05714787
• Lead Sponsor: Centre Hospitalier Universitaire de Nice

Brief Summary

It is well known that some chronic respiratory pathologies such as asthma or chronic obstructive pulmonary disease (COPD) are associated with an increased risk of osteoporosis, due to the pathology itself and the therapies implemented (per-os or inhaled corticosteroids). Osteoporosis leads to an increased risk of fragility fracture, with an increased morbidity and mortality associated with severe fractures such as vertebral fractures. Also, osteoporotic vertebral fractures often occur at the thoracolumbar hinge, resulting in worsening of the thoracic kyphosis. However, to the best of our knowledge, the prevalence of osteoporotic vertebral fractures measured by CT scan in patients with interstitial lung disease (ILD) is not known. For these patients who already have impaired respiratory function, the appearance of vertebral fractures could impact their management and worsen their prognosis (additional restrictive syndrome, difficulties in analgesics management because of respiratory contraindications, difficulties in wearing a corset, etc...). In this context, it appears interesting to define the prevalence of osteoporosis and osteoporotic vertebral fractures at the thoracic spine and the thoraco-lumbar hinge in a population of patients followed for ILD. So, the main objective of this study is to describe the prevalence of vertebral osteoporotic fractures in an overall cohort of patients with ILD.

Primary Outcome Measures

Name	Time	Method
Presence or absence of vertebral fracture in the global cohort	6 years	a vertebral fracture is considered if a decrease in height of the vertebral plateau by more than 20 % on an examination of chest CT scan on sagittal section after multiplanar reconstruction is observed.

Secondary Outcome Measures

Name	Time	Method
Presence or absence of vertebral fracture in subgroups	6 years	a vertebral fracture is considered if a decrease in height of the vertebral plateau by more than 20 % on an examination of chest CT scan on sagittal section after multiplanar reconstruction is observed.
To compare bone mineral density in Hounsfield Unit of patients with or without at least one vertebral fracture.	6 years	Bone mineral density in hounsfield unit is evaluated by measuring trabecular attenuation in an ovoid region of interest on axial T12 section
