In a new study, researchers found that aspirin could be used to treat the world’s deadliest infectious disease.
The research was conducted by a team at the Centenary Institute in Sydney.
Tuberculosis—which affects a third of the global population—currently kills two million people every year.
The spread of multi-drug resistant strains means antibiotics are becoming less effective.
To find new treatment options, the team infected zebrafish with a close relative of tuberculosis to determine how the deadly bacterium survives within its host.
The results showed that platelets—the cells which form blood clots—interact with the bacteria, helping them evade the host’s immune system.
This means that doctors can use cheap, safe anti-platelet drugs like aspirin to block this interaction and to stop the bacteria from growing.
The research showed that zebrafish treated with aspirin or other antiplatelet drugs had half the bacterial growth of untreated fish.
This is the first time that platelets have been linked to a direct effect on bacterial growth in an animal model.
This finding has prompted other researchers to look back into hospital records of people who had TB.
They show that patients who took aspirin while they were infected had better outcomes than those who didn’t.
Further research is needed to determine whether the same outcomes will be seen in humans.
The lead author of the study is Dr. Elinor Hortle.
