KBP-7072 outperformed comparator agents, including ceftazidime (40.3%S [CLSI]), gentamicin (48.2%/48.2%S [CLSI/EUCAST]), levofloxacin (39.5%/37.9%S [CLSI/EUCAST]), meropenem (42.0%/42.0%S [CLSI/EUCAST]), piperacillin-tazobactam (33.3%S [CLSI]) and all tetracycline-class comparator agents that include doxycycline (67.3%S, [CLSI], minocycline (73.8%S [CLSI]), tetracycline (37.2%S [CLSI]), and tigecycline (79.5% inhibited by ≤2 mg/L). The potent in vitro activity of KBP-7072 against recent geographically diverse, molecularly characterized and drug-resistant A. baumannii isolates supports continued clinical development for the treatment of serious infections including those caused by A. baumannii.

Journal: Antimicrobial Resistance and Molecular Characterization of Gene Cassettes from Class 1 Integrons in Pseudomonas aeruginosa Strains. (Pubmed Central) - Apr 7, 2021
Carbapenem-sensitive P. aeruginosa (CS-PA) isolates displayed 23 patterns, and the predominant multidrug resistance phenotype was CIP-levofloxacin (7.23%, 6/83)...Six gene cassette arrays were detected, the most prevalent being aacA4-blaOXA101-aadA5 in five isolates (4.4%, 5/113)...Some of the genes carried were similar to those in other species, but some had shared characteristics among the P. aeruginosa isolates. Long-standing drug resistance genes appeared to be under elimination in P. aeruginosa, whereas integrons conferring resistance to commonly used clinical drugs such as β-lactamases, fluoroquinolones, and even carbapenems, as well as some other gene elements, were found to be newly integrated.

Preliminary safety assessment on all RFB formulations towards osteoblast and fibroblast cell lines demonstrated that a reduction on cell viability was only observed for the positively charged liposomes. Overall, negatively charged RFB liposomes are a promising approach against biofilm S. aureus infections and further in vivo studies should be performed.

Levofloxacin treatment at the concentration of ≥2 × MIC consistently resulted in the long-lasting and sustainable inhibition of bacterial growth for 48 h. The addition of minocycline or tigecycline weakened the killing effect of fluoroquinolones during the first 10 h. The minocycline-ciprofloxacin or minocycline-levofloxacin combinations achieved the lowest colony-forming unit counts at 48 h. Zebrafish treated with minocycline or a combination of minocycline and levofloxacin had the highest survival rate (70%). The results of these in vitro and in vivo studies suggest that the combination of minocycline and levofloxacin is the most effective therapy approach for E. anophelis infection.

However, due to the different testing conditions and determination protocols of the growth of the microfluidic based rapid AST, a few results are not identical to the conventional methods using optical density. This result suggests that microfluidic based rapid AST methods require further research on the inoculum effect for practical use in hospitals and can then be used for effective antibiotic prescriptions.

Clinical, Review, Journal: Optimization Strategies Aimed to Increase the Efficacy of Helicobacter pylori Eradication Therapies with Quinolones. (Pubmed Central) - Apr 2, 2021
Unfortunately, resistance to quinolones is easily acquired and is increasing in most countries, being associated with a decrease in the eradication rate of H. pylori. In summary, a quinolone (mainly levofloxacin)-containing regimen is an encouraging second-line (or even third-line) strategy, and a safe and simple alternative to bismuth quadruple therapy in patients whose previous H. pylori eradication therapy has failed.

Interestingly, the use of intravenous ceftriaxone measured as defined daily dose per 100 bed days was decreased by 82% (94.32 vs. 16.68; p = 0.008), whereas oral levofloxacin use was increased by 84% (26.75 vs. 172.29; p = 0.008) in the intensive care unit. Overall, involvement of higher administration in multidisciplinary ASP committees, daily audit and feedback by clinical pharmacists and physicians with infectious disease training, continuous educational activities about antimicrobial use and resistance, use of local antimicrobial prescribing guidelines based on up-to-date antibiogram, and support from the intensive care team can optimize antibiotic use in Saudi healthcare institutions.
