Summary: This study aimed to investigate the difference in target attainment of meropenem between plasma and epithelial lining fluid (ELF). The study found that some patients did not achieve the target attainment in both plasma and ELF, and those who achieved target attainment in plasma did not necessarily have the same effect in ELF. Patients with a higher creatinine clearance rate may have poorer target attainment in ELF. Additionally, the dosage and loading dose may also affect the target attainment.

Summary: The study demonstrated that dalbavancin has the ability to effectively eradicate intraosteoblastic reservoir of Staphylococcus aureus in bone and joint infections. It showed significant reduction in bacterial inoculum at both low concentration and standard therapeutic doses, with similar efficacy to vancomycin but less efficient than rifampicin. Dalbavancin was found to be the only molecule significantly active at a low concentration.

Summary: This study investigated the long-term plasma pharmacokinetics of dalbavancin in outpatients with ABSSSI or osteoarticular infections who were treated with either one or two doses of 1500 mg. The results showed that dalbavancin exposure exceeded previously suggested pharmacodynamic targets, indicating a need for optimization in the treatment of osteoarticular infections.

Summary: This article describes the population pharmacokinetics of temocillin administered via continuous infusion versus intermittent infusion in critically ill patients with pneumonia. The study also examines the penetration ratios of the drug in the epithelial lining fluid/plasma and determines the probability of achieving target concentrations for a range of MICs. The results show that continuous infusion provides better PK/PD indexes but still falls below recommended doses for systemic infections, unless the patient has moderate renal impairment.

Summary: SPR206, a next-generation polymyxin, shows promise for treating multidrug-resistant (MDR) Gram-negative infections. A Phase 1 bronchoalveolar lavage (BAL) study was conducted to evaluate SPR206's safety and pharmacokinetics in healthy volunteers. The study demonstrates the pulmonary penetration of SPR206 and supports its further development for the treatment of serious infections caused by MDR Gram-negative pathogens.

Summary: Ceftolozane/tazobactam (C/T) is a novel cephalosporin with tazobactam recently approved for hospital-acquired and ventilator-associated pneumonia. A study evaluated the pharmacokinetics of C/T in adult patients with nosocomial pneumonia, showing significant differences in distribution of ceftolozane and tazobactam in plasma and pulmonary epithelial lining fluid between pneumonia patients and healthy participants.

Summary: Tuberculosis lung lesions are complex and harbor heterogeneous microenvironments that influence antibiotic effectiveness. Major strides have been made recently in understanding drug pharmacokinetics in pulmonary lesions, but the bacterial phenotypes that arise under these conditions and their contribution to drug tolerance are poorly understood.

Summary: A population pharmacokinetic model of dalbavancin was developed using data from 1124 pediatric patients. Simulations showed that single-dose regimens of dalbavancin had adequate pharmacokinetic/pharmacodynamic target attainment in pediatric patients.

Summary: WCK 4282 demonstrated clinical exposure efficacies against various Enterobacterales and Pseudomonas aeruginosa isolates in animal experiments. It showed potential activity against cefepime-resistant strains, particularly those producing extended-spectrum beta-lactamase and cephalosporinase.

Summary: Physiologically based pharmacokinetic models have gained popularity in drug development and regulatory science. This study validates the model's effectiveness in predicting drug-drug interaction and the pharmacokinetics of antiretroviral and anti-TB drugs through mathematical solving and sensitivity analysis.

Summary: This study analyzed the pharmacokinetics/pharmacodynamics of caspofungin in plasma and peritoneal fluid samples from liver transplant recipients. The results showed that the concentration of caspofungin in peritoneal fluid was low, suggesting a potential risk of resistance.

Summary: This study investigates the potential bias in the estimation of monoclonal antibody (mAb) concentrations in the epithelial lining fluid (ELF) using the bronchoalveolar lavage (BAL) method. It demonstrates that the unbalanced extraction of mAb and urea could lead to underestimated ELF concentrations, but the choice of lavage volume does not significantly affect the partitioning of mAb into ELF.

Summary: The study showed that the combination of ceftazidime and tobramycin has a good bactericidal effect and can suppress resistance in hypermutable Pseudomonas aeruginosa strains. In vitro experiments simulating treatment regimens revealed that high-dose combination therapy is more effective against susceptible strains.
