Abstract:
The recent increase in our knowledge of human gut microbiota has changed our view on antibiotics. Antibiotics are, indeed, no longer considered only beneficial, but also potentially harmful drugs, as their abuse appears to play a role in the pathogenesis of several disorders associated with microbiota impairment (eg, Clostridium difficile infection or metabolic disorders). Both drug-related factors (such as antibiotic class, timing of exposure or route of administration) and host-related factors appear to influence the alterations of human gut microbiota produced by antibiotics. Nevertheless, antibiotics are nowadays considered a reliable therapy for some non-communicable disorders, including IBS or hepatic encephalopathy. Moreover, some antibiotics can also act positively on gut microbiota, providing a so-called 'eubiotic' effect, by increasing abundance of beneficial bacteria. Therefore, antibiotics appear to change, for better or worse, the nature of several disorders, including IBS, IBD, metabolic disorders or liver disease. This reviews aims to address the potential of antibiotics in the development of major non-communicable disorders associated with the alteration of gut microbiota and on newly discovered therapeutic avenues of antibiotics beyond the cure of infectious diseases.
Insights
Antibiotics impact the gut microbiota, potentially causing harm or offering therapeutic benefits for non-communicable disorders. Understanding these effects is crucial for new treatment strategies beyond infections.
Area of Science:
- Microbiology
- Pharmacology
- Gastroenterology
Background:
- The human gut microbiota plays a critical role in health and disease.
- Antibiotics, while essential for treating infections, can disrupt the gut microbiota.
- Emerging evidence links antibiotic-induced microbiota alterations to various non-communicable disorders.
Purpose of the Study:
- To review the dual role of antibiotics in the pathogenesis and treatment of non-communicable disorders.
- To explore the impact of antibiotics on gut microbiota composition and function.
- To discuss novel therapeutic applications of antibiotics targeting microbiota-related conditions.
Main Methods:
- Literature review of studies on antibiotics and gut microbiota.
- Analysis of drug-related and host-related factors influencing microbiota alterations.
- Examination of antibiotic effects on conditions like IBS, IBD, metabolic disorders, and liver disease.
Main Results:
- Antibiotic abuse is associated with disorders like Clostridium difficile infection and metabolic issues.
- Antibiotics can be beneficial for conditions such as Irritable Bowel Syndrome (IBS) and hepatic encephalopathy.
- Some antibiotics exhibit a 'eubiotic' effect, promoting beneficial gut bacteria.
Conclusions:
- Antibiotics significantly influence the gut microbiota, impacting various non-communicable diseases.
- Antibiotics offer potential therapeutic avenues for microbiota-related disorders beyond infectious diseases.
- Further research is needed to fully elucidate the complex interplay between antibiotics, microbiota, and host health.
