Outline of Final Research Achievements

Carbapenem-resistant Enterobacteriaceae (CRE) is among the most severe threats to public and clinical health because of their high levels of resistance to various antibiotics. We assessed the efficacy of combination therapy with meropenem (MEM) and cefmetazole (CMZ) against IMP-, KPC-, and NDM-producing CRE.
In vitro studies showed the potential effectiveness of combination therapy using existing antimicrobials, MEM and CMZ, against CRE infections. Further investigations including in vivo animal studies and clinical studies are warranted to corroborate clinical utility of the new combination therapy.

Academic Significance and Societal Importance of the Research Achievements

薬剤耐性菌の出現により我々は難治性細菌感染症に直面している。中でもカルバペネム耐性腸内細菌科細菌(CRE)は脅威的なスピードで世界へ拡散しており、CRE感染症に対する有効な治療戦略の模索が急務である。しかし現実的には開発シーズの不足や莫大な開発費用のため、産学領域での新規抗菌薬の開発は滞っているのが現状である。
本研究は既存抗菌薬を応用することで、新規抗菌薬の開発を待たずしてCRE感染症に有効な治療戦略を模索することが可能な一例を示したものである。今後、同様の研究が継続され、新たなサルベージ治療が発展することが期待される。
