Tuberculosis - a continuing threat to global health 

Up until the coronavirus (COVID-19) pandemic, tuberculosis (TB) was the leading cause of death from a single infectious agent, ranking above HIV/AIDS1. The World Health Organization (WHO) estimated that around 10 million people fall ill with active TB every year, and sadly 1.6 million people died from TB in 2021 alone1. However, the challenge with the global epidemic of TB is that the devastating impact of active TB is just the beginning.

TB facts and figures

Latent tuberculosis infection (LTBI) – critical to TB management, especially in the immunosuppressed

Almost 2 billion people, or around 25% of the global population are infected with latent TB2.

LTBI screening is increasingly being recognized as critical to TB management. LTBI screening is the process of identifying and testing individuals who may be at risk of becoming infected with TB, or those who may be at high risk of progression from latent to active TB, like the immunosuppressed population.

Due to their weakened immune systems, immunosuppressed patients have reduced T cell numbers, and their T cells may not be functioning properly, meaning that they produce less interferon-gamma. This decreased production poses a challenge in accurate diagnosis, and it is essential to choose the right interferon-gamma release assay (IGRA) methodology when testing for LTBI in immunosuppressed patients.

The WHO, ECDC, and CDC are unified in their endorsement of interferon-gamma release assay (IGRA) tests for LTBI screening in the immunosuppressed.
