Overview

The purpose of this study is to describe bone status on patients with genetic hemochromatosis, at diagnostic time and his evolution under treatment.

Full Title of Study: “Bone Status on Patients With Genetic Hemochromatosis : a 3 Years Descriptive and Evolutionary Study.”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: August 2014

Detailed Description

Bone diseases have been recognized recently as complications of genetic hemochromatosis. Further studies are needed to describe the role of iron in bone injuries. The purpose of this study is to describe bone status on patients with genetical hemochromatosis, at diagnostic time and his evolution under treatment.

Clinical Trial Outcome Measures

Primary Measures

  • Bone mineral density
    • Time Frame: Change from baseline in bone mineral density at three years
    • Vertebral and hips Dual energy X-ray Absorptiometry (DXA)

Secondary Measures

  • Predictive value of iron overload on Bone Mineral Density
    • Time Frame: 1 day
  • Number of vertebral fractures
    • Time Frame: 3 years
  • Number of peripheral fractures
    • Time Frame: 3 years
  • Number and location of joint lesions detected by the examination (pain and swelling)
    • Time Frame: 3 years
  • Determination of genetic polymorphism of BMP 2 and 4
    • Time Frame: Baseline
