Phage therapy is the rising star on the horizon of antibiotic-resistant treatments. As the world grapples with the escalating antibiotic resistance crisis, scientists and healthcare professionals turn to an age-old natural predator of bacteria: bacteriophages. These viruses specifically target and destroy bacteria and are being revisited as a potential solution to combat resistant infections.
This article delves into the future of phage therapy, its current medical applications, and the challenges and opportunities it presents as an alternative to traditional antibiotics.
What might bacteriophages be used for in the future?
Bacteriophages, or phages, offer a promising avenue for various applications beyond treating bacterial infections. In agriculture, phages could be employed to control bacterial pathogens in crops, reducing the need for chemical pesticides and enhancing food safety.
Researchers like Dr. Martha Clokie are motivated by an ambition to find cures for difficult-to-treat diseases, mainly due to the increasing number of antibiotic-resistant infections. Her research explores the potential of using naturally occurring viruses, known as bacteriophages, to treat antibiotic-resistant infections.
Dr. Martha Clokie, a prominent phage researcher, is “investigating alternative treatments for Clostridium difficile (C. diff), a bacteria that can infect the bowel and cause diarrhea.” In her research, she claims to have discovered “a large set of phages that effectively kill this pathogen.”
In biotechnology, phages could be harnessed for targeted gene editing, offering precision tools for genetic modifications in bacteria. Furthermore, phages, such as bioremediation, might play a role in environmental management, which could help break down harmful bacteria in contaminated sites.
This goes to show that viruses aren’t always harmful.
The future of phage therapy
The urgent need for antibiotic alternatives drives the resurgence of interest in phage therapy. Advances in genetic engineering are paving the way for the development of customized phages that can be tailored to target specific bacterial strains. This precision medicine approach could revolutionize how infections are treated.
According to Dr Mariam Dadiani, physician of internal medicine at the Eliava Phage Therapy Centre in Georgia, efforts are being made “to increase the awareness about the role of bacteriophages in the treatment of multi-drug-resistant chronic infections.” Dr. Daddiani further notes that “behind our success cases lies the evidence to support the development of phage therapy for widespread use in human health.”
Clinical trials are crucial for establishing the efficacy and safety of phage therapy. Researchers are optimistic that with continued investment and research, this therapy could become a mainstream treatment option within the next decade.
Is phage therapy for antibiotic resistance being used in medicine?
Yes, bacteriophages are currently being used in medicine, albeit on a limited scale. Phage therapy has been part of the medical landscape in countries like Georgia and Poland for decades. For instance, the Eliava Institute in Georgia has pioneered phage research and therapy since the early 20th century.
In recent years, Western countries have begun to explore phage therapy through clinical trials and compassionate use cases, particularly for patients with antibiotic-resistant infections.
In which countries can you have phage therapy?
Phage therapy is most readily available in Georgia, Poland, and Russia, where it has been integrated into healthcare practices. In the United States and parts of Europe, it is accessible through clinical trials or under compassionate use protocols. The regulatory landscape is evolving, with agencies like the FDA showing increased interest in supporting phage therapy research.
How much does phage therapy cost?
The cost of phage therapy can vary significantly. Due to existing infrastructure and expertise, the costs may be relatively lower in countries with well-established practices, such as Georgia. In contrast, in countries where it is still emerging, costs can be higher, often requiring personalized treatment plans and laboratory work to identify suitable phages.
Live UTI Free says, “Some patients travel internationally for phage therapy. The Phage Therapy Center in Georgia offers treatment to patients worldwide for about US$3,000-$5,000, depending on the treatment. This cost, however, does not include travel, lodging, or additional expenses for tests on bacterial samples.”
What is bad about phage therapy?
While phage therapy holds great promise, it is not without challenges. One major drawback is the specificity of phages; A phage that targets one bacterial strain may not affect another, necessitating precise identification of the pathogen. Additionally, bacteria can develop resistance to phages, similar to antibiotic resistance. Regulatory hurdles and a lack of standardized treatment protocols also pose significant challenges to the widespread adoption of this therapy.
Is phage therapy an alternative to antibiotics?
Phage therapy is seen as complementary to antibiotics rather than a direct replacement. It offers a viable alternative for treating infections that do not respond to conventional antibiotics.
“Substantial progress is being made such that selection, engineering, and synthetic production of phages may make it possible for these lethal enemies of bacteria to be harnessed as potent allies in our battle against antimicrobial resistance.” Sais Robert T Schooley, MD, University of California San Diego, in his paper published in the National Library of Medicine titled: Exploring Bacteriophage Therapy for Drug-Resistant Bacterial Infections
Conclusion
Bacteriophages represent a beacon of hope in the fight against antibiotic-resistant infections. While there are challenges to overcome, the potential benefits of phage therapy are immense. As research progresses and regulatory frameworks evolve, this therapy could become integral to modern medicine, offering a targeted, effective, and sustainable solution to bacterial infections.
Phage therapy’s future is bright, and its role in healthcare is poised to expand significantly in the coming years. When it comes to modern medicine, we have many avenues that we can explore. Some of these will also require us to protect cultural heritage, as with some natives in the Amazon, whose demise would be a disaster for modern medicine.
