Recent trials in the UK have introduced an innovative approach to combatting superbugs, with researchers exploring the use of “poo pills,” scientifically known as faecal microbiota transplants (FMT). These capsules contain freeze-dried stool from healthy donors and aim to help manage dangerous infections caused by antibiotic-resistant bacteria. The initiative originates from an urgent need to tackle the global crisis of antimicrobial resistance, which claims up to a million lives annually.

The clinical trials are currently underway at Guy’s and St Thomas’ hospitals in London, where researchers have reported “really promising signals” from a group of 41 patients. These pills work by introducing beneficial bacteria into the gut, where they compete with harmful microbes for resources, potentially eliminating them or bringing their levels down to a manageable threshold. Dr. Merrick, a leading figure in the trials, emphasises the dual role of these capsules: not only do they address existing infections, but they also enhance the body’s overall microbial balance, which is key to maintaining health.

In a separate but related study, researchers at King’s College London have launched the PROMISE trial, focusing on patients suffering from advanced liver diseases such as cirrhosis. This condition has been recognised as the third leading cause of mortality in the UK, particularly affecting younger adults. The trial aims to involve around 300 participants, randomly assigning them to receive either the faecal capsules or a placebo every three months over a period of two years. The underlying rationale is that individuals with liver damage often harbour increased levels of harmful gut bacteria, rendering them more vulnerable to infections that traditional antibiotics may struggle to combat.

Notably, the British Liver Trust supports the King’s College trial, recognising its potential to reduce dependency on antibiotics, thereby addressing the broader issue of antimicrobial resistance. The hope is that improving gut health through FMT could significantly enhance the immune response in these patients, ultimately leading to better health outcomes and less strain on health care systems.

Previous studies underscore the efficacy and safety of faecal microbiota transplants beyond liver disease, showcasing their success in treating various gastrointestinal disorders and even some neurological conditions. As interest in these “crapsules” grows, they represent a novel and promising frontier in medical treatment, aiming to restore balance within the human microbiome and combat the rise of superbugs on multiple fronts.

These trials could lead to significant advancements not only in treating infections but also in reshaping how chronic diseases are managed, potentially changing the narrative around antibiotic resistance and improving patient quality of life.
