Summary: A multicenter international prospective observational pharmacological study in adult patients (≥18 years) treated with ceftazidime/avibactam (CAZ/AVI) alone or with CAZ/AVI plus fosfomycin (FOS) for infection due to carbapenem-resistant Enterobacterales (CRE) (KPC and/or OXA-48).

Summary: The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treati...

Summary: CRAB infections in ICUs are on the rise, leading to higher morbidity, mortality, and healthcare costs due to resistance to most antibiotics, including carbapenems. The main resistance mechanisms include carbapenemases, efflux pumps, and changes in the bacterial cell wall. Current treatments include polymyxins (Colistin, Polymyxin B), which are effective but can lead to resistance, aminoglycosides ...
