  Purpose

Despite the prevalence of osteopenia and osteoporosis in the HIV positive population, relatively little is known about the underlying pathology. This prospective cohort study aims to gain further understanding about a number of issues relating to low bone mineral density in HIV-infected subjects.


Condition
Osteoporosis

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Further study details as provided by University College Dublin:

Primary Outcome Measures:
  • Bone pathology [ Time Frame: 3 years ] [ Designated as safety issue: No ]
    To describe abnormalities in bone pathology in bone biopsies from HIV-infected subjects with low bone mineral density by comparing biopsy indices to reference ranges.


Secondary Outcome Measures:
  • Rates of change in bone mineral density [ Time Frame: 3 years ] [ Designated as safety issue: No ]
    To determine rates of change in bone mineral density in HIV-positive patients compared to HIV-negative controls


Other Outcome Measures:
  • Fracture incidence [ Time Frame: 3 years ] [ Designated as safety issue: No ]
    To assess the validity of currently available fracture risk assessment tools in predicting fracture risk in HIV-infected patients.


Biospecimen Retention:   Samples With DNA

serum, plasma, buffy coat, urine


Estimated Enrollment: 500
Study Start Date: February 2011
Estimated Study Completion Date: October 2013
Estimated Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
HIV positive
HIV negative

Detailed Description:

This study will follow HIV positive and negative subjects annually for 3 years. The aims of this study include:

  • to describe the pathology underlying low bone mineral density
  • to assess the relationship between low bone mineral density and antiretroviral therapy exposure
  • to assess the relationship between low bone mineral density and vitamin D /PTH status and/or markers of bone metabolism
  • to assess the relationship between osteopenia and subsequent changes in bone mineral density and markers of bone metabolism
  • to assess the validity of the currently available fracture risk assessment tool in predicting fractures in HIV positive populations
