Study Notes
The Revival of β-Lactam Antibiotics
- β-Lactam antibiotics are the most widely used and successful antibacterial agents, but their effectiveness is challenged by resistance mediated by beta-lactamases.
- The combination of a β-lactam with a β-lactamase inhibitor (BLBLI) can restore the efficacy of otherwise ineffective antibiotics.
Development of New Antibacterial Agents
- Many associations of BLs (BLBLIs) are under research and development, with some granted the Qualified Infectious Disease Product (QIDP) designation.
- Pharmaceutical companies are investing in research and development of new antibacterials, including renewed β-lactam antibiotics with activity against problematic and multidrug-resistant Gram-negative pathogens.
AIDsense: A Novel Detection Method
- AIDsense is a novel method for β-lactamase detection with direct potential clinical applications as a diagnostic tool.
- It allows clinics/laboratories to rapidly confirm beta-lactamase resistance and identify the responsible gene, which is critical for epidemiological purposes.
β-Lactam Antibiotics and β-Lactamase Inhibitors
- β-Lactam antibiotics inhibit bacterial cell wall synthesis (peptidoglycan), leading to cell lysis.
- β-Lactamase inhibitors, such as Avibactam, can restore the activity of different classes of β-lactams, including Cephalosporin, against multi-drug resistant bacterial infections.
- Meropenem-Avibactam has been a valuable agent for treating severe infections due to carbapenemase-producing Enterobacteriaceae since 2017.
Mitigating Resistance
- Strategies to mitigate the spread of resistance include optimizing current β-lactamase inhibitors and developing novel “renewed” β-lactam antibiotics.
- The development of new antibacterial agents is urgently needed to combat drug-resistant infections.
