Next-generation precision antimicrobials: towards personalized treatment of infectious diseases

Cesar de la Fuente-Nunez et al. Curr Opin Microbiol. 2017 Jun.

Abstract

Antibiotics started to be used almost 90 years ago to eradicate life-threatening infections. The urgency of the problem required rapid, broad-spectrum elimination of infectious agents. Since their initial discovery, these antimicrobials have saved millions of lives. However, they are not exempt from side effects, which include the indiscriminate disruption of the beneficial microbiota. Recent technological advances have enabled the development of antimicrobials that can selectively target a gene, a cellular process, or a microbe of choice. These strategies bring us a step closer to developing personalized therapies that exclusively remove disease-causing infectious agents. Here, we advocate the preservation of our beneficial microbes and provide an overview of promising alternatives to broad-spectrum antimicrobials. Specifically, we emphasize nucleic acid and peptide-based systems as a foundation for next-generation alternatives to antibiotics that do not challenge our microbiota and may help to mitigate the spread of resistance.

Figure 1. Precision antibiotics
Hypothetical graphic showing treatment of specific disease causing bacterial infections with precision antimicrobials. For example, in the left side of the figure, we have an infection caused by the orange bacteria, which are surrounded by beneficial microbiota bacteria (colored in green and purple). In this scenario, a precision peptide designed to target the green pathogen will exclusively target this organism. The same applies to the other two examples, where peptides against green (center image) and purple bacteria (right image) would selectively remove these organisms.

Figure 2. Personalized approach to infectious diseases
Potential of precision antimicrobial strategies such as the ones described in this review (shown on the left of the figure) for personalized treatment of infectious diseases. In the future, early diagnostic methods may enable rapid identification of disease-causing pathogens, and precision antimicrobial agents may allow specific treatment of infection, while leaving non-causative, beneficial microbial communities unaffected. These advances, coupled with early-diagnostic tools for rapid detection of infectious agents, will constitute the foundation of personalized treatment of infectious diseases.
