A more intensive biomedical research approach is necessary to control and ultimately eliminate tuberculosis (TB), according to a perspective published in the March 2018 issue of The American Journal of Tropical Medicine and Hygiene.Researchers discuss the need to modernize TB research by applying new diagnostic, therapeutic, and vaccine approaches.
Tuberculosis a bacterial infection that typically infects the lungs is one of the oldest known human diseases and the leading infectious cause of death worldwide. The authors recall the significant HIV/AIDS research advances made in the nearly 37 years since AIDS was first recognized and encourage the scientific community to strive for comparable TB milestones.
Specifically, the authors call for systems biology approaches to fill critical knowledge gaps in understanding how Mycobacterium tuberculosis (Mtb) infection causes disease.
Such research could help explain why some people infected with Mtb have latent infections and show no signs of disease while others, especially those co-infected with HIV, become sick. The perspective also underscores the need for improved diagnostic tests, including those that can detect Mtb in various specimens as well as rapid, inexpensive tests that can detect drug-resistant TB.
Lengthy and complex treatment regimens and an increasing number of multi-drug-resistant TB infections make the disease increasingly difficult to cure. The authors note that the ultimate treatment goal should be drug combinations administered for shorter time periods that can cure people infected with any strain of Mtb.
Another research goal is a safe and more broadly effective vaccine, which remains one of the most difficult challenges, according to Drs. Fauci and Eisinger. However, they explain, a vaccine and other significant advances are possible with an innovative and aggressive biomedical research program and rapid translation of results into global control strategies.
