Abstract:
Foot infections are a major cause of morbidity in diabetic patients. Staphylococcus aureus is the most important pathogen in mild infections; moderate to severe infections are frequently polymicrobial. Multidrug resistance is an increasing problem in isolates from diabetic feet. Worldwide, up to 30% of patients with diabetic foot infection (DFI) are colonised with methicillin-resistant S. aureus (MRSA), whilst extended-spectrum beta-lactamase-producing Gram-negative bacteria are also common in some countries. This emergence of drug resistance has coincided with the launch or imminent availability of many new antibiotics. Most of these were developed to target multidrug-resistant Gram-positive bacteria, although some have a spectrum of activity that includes Gram-negative bacteria and anaerobes. There is a variable amount of experience with these agents in treating skin and skin-structure infections (SSSIs), especially for DFI. However, at least some have a spectrum of activity and/or pharmacological properties that suggest that they may be of value in managing DFIs. The aim of this paper is to review evidence for the efficacy of new antibiotics in the management of SSSIs, including any data relating specifically to the diabetic foot, and to consider where they might fit into the therapeutic armory against DFI.
Insights
Diabetic foot infections (DFI) present challenges due to rising antibiotic resistance, including MRSA. New antibiotics show promise for treating these complex skin infections, offering potential new therapeutic options.
Area of Science:
- Infectious Diseases
- Dermatology
- Pharmacology
Background:
- Diabetic foot infections (DFI) are a significant cause of illness and complications in diabetic patients.
- Increasing multidrug resistance, including methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum beta-lactamase-producing Gram-negative bacteria, complicates DFI treatment.
- Emergence of novel antibiotics coincides with rising antimicrobial resistance in DFI pathogens.
Purpose of the Study:
- To review the evidence for the efficacy of new antibiotic agents in treating skin and skin-structure infections (SSSIs).
- To specifically evaluate the role of new antibiotics in managing diabetic foot infections (DFI).
- To determine the potential place of these new agents in the therapeutic strategies for DFI.
Main Methods:
- Literature review of existing evidence on new antibiotic efficacy in SSSIs.
- Inclusion of data specifically pertaining to diabetic foot infections.
- Analysis of antibiotic spectrum of activity and pharmacological properties relevant to DFI.
Main Results:
- Several new antibiotics have been developed, primarily targeting multidrug-resistant Gram-positive bacteria, with some activity against Gram-negative bacteria and anaerobes.
- Variable clinical experience exists with these agents in SSSIs, with limited specific data for DFI.
- Some new antibiotics possess characteristics suggesting potential utility in DFI management.
Conclusions:
- New antibiotics offer potential therapeutic options for managing SSSIs, including those in diabetic patients.
- Further research and clinical data are needed to establish the definitive role of these agents in DFI treatment.
- Careful consideration of spectrum of activity and pharmacological properties is crucial for selecting appropriate new antibiotics for DFI.
