Abstract:
Antimicrobial resistance is a problem that affects healthcare delivery around the globe. Factors associated with antimicrobial resistance include overuse or misuse of antimicrobial agents, immunosuppressed patients, and increased technology. Cellular mechanisms of antimicrobial resistance include the decreased uptake of a drug, efflux of the drug, enzymatic inactivation, and alterations in the antimicrobial target site. New treatment options are currently available for resistant organisms. Therapeutic strategies such as antibiotic control policies and antibiotic "cycling" have been proposed as methods for minimizing the emergence of more resistant organisms. Little evidence is available to indicate that these strategies are effective in limiting the emergence of resistance. Clinicians are urged to be judicious in their use and choice of antimicrobials.
Insights
Antimicrobial resistance is a growing global health threat. While new treatments exist, evidence for strategies like antibiotic cycling is limited, urging judicious antimicrobial use.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Antimicrobial resistance (AMR) poses a significant challenge to global healthcare.
- Factors contributing to AMR include antimicrobial agent misuse, immunocompromised patients, and technological advancements.
- Cellular mechanisms of AMR involve reduced drug uptake, efflux, enzymatic inactivation, and target site alterations.
Purpose of the Study:
- To review the current landscape of antimicrobial resistance.
- To discuss emerging treatment options and proposed control strategies.
- To emphasize the need for judicious antimicrobial prescribing.
Main Methods:
- Literature review of antimicrobial resistance mechanisms and therapeutic strategies.
- Analysis of factors contributing to the development of resistance.
- Evaluation of proposed interventions for minimizing resistance emergence.
Main Results:
- Established cellular mechanisms of antimicrobial resistance.
- Identified contributing factors to the rise of resistant organisms.
- Noted a lack of strong evidence supporting the effectiveness of antibiotic control policies and cycling.
Conclusions:
- Judicious use and selection of antimicrobials by clinicians are crucial.
- Further research is needed to validate the efficacy of proposed resistance-minimizing strategies.
- Addressing antimicrobial resistance requires a multifaceted approach including responsible prescribing practices.
