February 15, 2023 updated by: Thai Red Cross AIDS Research Centre

Bone Health and Vitamin D Status in Thai HIV-1 Infected and Uninfected Adults (A Substudy of TNT-HIV 003: Trends of Morbidity and Mortality Among Thai HIV-infected and HIV-uninfected Patients: a Five-year Prospective Cohort Study)

This study will compare and assess the prevalence of osteopenia and vitamin D deficiency as well as effects of TDF on the patients' bone among HIV positive and negative patients.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

To determine the prevalence of osteopenia and vitamin D deficiency in HIV-1 infected, HAART naive Thai patients compared to HIV-1 uninfected Thai participants. Furthermore, to determine the change in BMD after twelve months in HIV-1 infected Thai patients on a TDF-based HAART regimen compared to patients on a non-TDF containing regimen.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
