Finding biological signs that predict which TB-exposed children will get sick
Identifying correlates of risk for future tuberculosis disease progression in children (INTREPID)
This project looks for blood and other biological signs in children exposed to tuberculosis that show who is likely to develop TB disease.

What this research studies
As a parent, this work follows children who were exposed to TB and collects blood and other samples to look for biological signs that predict future illness. The team will include children of different ages and those living with HIV, and will examine whether common viral infections change these biomarker patterns. Laboratory tests and data analysis will be used to separate children likely to progress to active TB from those who are not. The aim is to create a more accurate test so preventive therapy can be given to the children who most need it.
Who could benefit from this research
Good fit: Children who have been exposed to someone with tuberculosis, especially young children and those living with HIV in high TB-burden areas, would be the ideal candidates.
Not a fit: People without recent TB exposure, most adults in low-risk settings, or those not in the study regions may not directly benefit from this work.
Why it matters
Potential benefit: If successful, this could help doctors target preventive TB treatment to the children most likely to get sick while avoiding unnecessary treatment for others.
How similar studies have performed: Previous biomarker studies in adults have shown some promising signals, but reliable predictive tests for progression in young children are limited and the effect of common viral infections on pediatric signatures is relatively untested.
