How TB progresses in young children with and without HIV
PROgression of Tuberculosis infECTion in young children living with and without HIV: the PROTECT study
This project looks for blood or other markers that can tell which young children with TB infection, including those living with HIV, are most likely to develop active TB so they can get preventive treatment early.

What this research studies
This project searches for patterns in blood and other samples from young children to find markers that show early signs of TB getting worse. Researchers will use stored samples and serial samples collected over time from children in Uganda, South Africa, The Gambia, and Vietnam to compare those who developed TB with those who did not. The aim is to find marker signatures that meet WHO accuracy targets so they could be turned into simple point-of-care tests to guide preventive therapy. Children with and without HIV will be included to see how HIV affects progression and marker performance.
Who could benefit from this research
Good fit: Ideal candidates are young children (especially under 5 years) who have been exposed to TB or have evidence of TB infection, including children living with HIV.
Not a fit: Adults, children without TB exposure or infection, and people with unrelated health issues are unlikely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, doctors could identify at-risk children earlier and offer preventive treatment to reduce TB deaths and severe illness.
How similar studies have performed: Some biomarker work in adults and older children has shown promise, but reliable early predictors of TB progression in very young children remain largely unproven.
