To give or not to give antibiotics is not the only question

Area of Science:

• Microbiology
• Infectious Diseases
• Pharmacology

Background:

• Antibiotic resistance is a growing global health threat, with bacteria evolving resistance to available drugs.
• Sir Alexander Fleming cautioned against antibiotic overuse decades ago, a concern now amplified by widespread resistance.
• Current guidelines often recommend longer antibiotic courses, but their necessity and impact on resistance are debated.

Purpose of the Study:

• To evaluate the effectiveness of shorter antibiotic treatment durations compared to longer regimens.
• To explore how antibiotic treatment duration influences the development and spread of antimicrobial resistance.
• To advocate for a re-evaluation of current antibiotic prescribing guidelines.

Main Methods:

• This is a Personal View article, presenting arguments and evidence from existing literature.
• Discussion of selective pressure exerted by antibiotic treatment on microbial populations.
• Analysis of the impact of treatment duration on the emergence of resistant bacterial clones.

Main Results:

• Shorter antibiotic regimens may be as effective as longer ones for common infections.
• Reduced antibiotic exposure through shorter treatments exerts less selective pressure, potentially slowing resistance.
• Longer treatments can promote the emergence of resistant commensal organisms.

Conclusions:

• Prescribing fewer antibiotics and using shorter treatment durations can be as effective as current longer guidelines.
• Shorter antibiotic courses are crucial for mitigating antimicrobial resistance by reducing selective pressure.
• Further research is needed to determine optimal treatment durations and identify biomarkers for guiding antibiotic therapy.
