Clinical Assessment of Patients With High Bone Mass Due to Mutation in Lrp5

September 9, 2010 updated by: Odense University Hospital

Clinical Assessment of Patients With High Bone Mass Due to Mutation in Low Density Lipoprotein l Receptor 5

The aim of the study is to describe patients with a high bone mass phenotype due to a mutation in the low density lipoprotein l receptor 5 gene (LRP5) and compare them with age and sex matched controls. Moreover, bone density and microarchitecture as well as markers of bone metabolism are evaluated

Study Overview

Status

Completed

Conditions

Detailed Description

Cases and controls are closely matched on age and sex and evaluated cross-sectionally.

Dual x-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HR-pQCT) are used in order to evaluate bone density as well as microarchitecture. Bone turnover markers and body composition are also measured.

Patients known to have a mutation in Lrp5 known to be causing a high bone mass phenotype

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Bone microarchitecture as assessed by high resolution quantitative computed tomography (HR-pQCT)
Time Frame: 12 weeks
HR-pQCT is used to evaluate bone microarchitecture, i.e. bone trabeculae, cortical thickness and trabecular number. Aim is to test if the microarchitecture of these patients are different that observed in normal controls
12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in bone turnover markers
Time Frame: 12 weeks
Markers of bone resorption and formation are investigated.
12 weeks
Bone mineral density
Time Frame: 12 weeks
DXA is used to evaluate bone mineral density at total hip, spine, whole body and forearm.
12 weeks
