Doctors use poo pills to flush out dangerous superbugs

In an innovative approach to combating dangerous superbug infections, doctors in the UK are exploring the use of “poo pills” containing freeze-dried faeces sourced from healthy donors. These stool samples are rich in beneficial bacteria that have shown promise in replacing antibiotic-resistant superbugs with a healthier gut microbiome. The novel treatment aims to address the pressing issue of infections that are resistant to antibiotics, a problem responsible for claiming the lives of millions of people annually.

Dr. Blair Merrick, who is conducting trials at Guys and St Thomas’ hospitals, emphasizes the importance of targeting the bowels as a major reservoir of antibiotic resistance in humans. The focus on eradicating drug-resistant superbugs from the gut is crucial, as these pathogens can spread to other parts of the body, leading to severe complications like urinary tract or bloodstream infections. While the concept of poo-pills may seem unconventional, faecal transplants have already been approved for treating severe diarrhoea caused by Clostridium difficile bacteria, showing early indications of success in eliminating superbugs as well.

Recent research has honed in on patients who have battled infections from drug-resistant bacteria in the past six months, with promising outcomes from the use of faecal-derived pills sourced from a stool bank. These pills undergo rigorous testing to ensure their safety, after which they are freeze-dried and encapsulated for targeted delivery to the intestines. Preliminary data suggests that patients receiving these poo pills demonstrate a diverse array of gut bacteria post-treatment, indicative of improved colonisation resistance against new infectious agents trying to infiltrate the microbiome.

The successful trial involving 41 patients at Guy’s and St Thomas’ hospitals in London underscores the potential of poo pills in combatting the rise of superbugs. Dr. Merrick expresses optimism about the therapeutic benefits of these treatments, highlighting the microbial competition between donor bacteria and drug-resistant pathogens within the gut. The development of microbiome-based therapies like poo pills holds promise in addressing antibiotic resistance and could revolutionize the future of medical interventions, particularly for individuals at heightened risk due to immunocompromised states caused by medical procedures or underlying conditions
