Summary

Background:

Tuberculosis (TB) is a health threat for people living with human immunodeficiency virus (HIV). People living with HIV are more likely than others to develop active TB. Also, TB makes HIV progress faster. TB is a leading cause of death among people in the West African country of Liberia. Researchers want to find an effective testing method for latent tuberculosis infection (LTBI) to help people living with HIV in Liberia.

Objective:

To compare the interferon-gamma release assay (IGRA) and tuberculin skin test (TST) as LTBI screening tests in people living with HIV in Liberia.

Eligibility:

People ages 18 and older who take part in NIH study #19-I-N014 and are scheduled to have or have had IGRA at a Month 12 HONOR study visit.

Design:

Participants will be screened with a medical history and physical exam. Their medical records and HONOR study records will be reviewed.

Participants will have TST. Purified protein derivative will be placed in the skin of their forearm. They will be observed for adverse reactions for 15 minutes. Between 48 and 72 hours after placement, they will have a second study visit to have the TST read. If they miss this time frame, they can return up to 7 days after placement. If they have a positive test result, they will have a chest x-ray. They will have a third study visit to review the results of the chest x-ray. They will be referred for clinical care if needed. They will take a pregnancy test if needed.

Participation will last from 2 days to 6 weeks.
