We report herein on two cases of bacteremia caused by daptomycin-resistant Corynebacterium striatum. In these cases, daptomycin-resistant C. striatum was detected after receiving daptomycin for the treatment of multidrug-resistant C. striatum bacteremia, and ERIC-PCR band patterns were identical among the isolates of C. striatum before and after daptomycin therapy. We performed an in vitro assay to determine whether daptomycin resistance is induced in nine clinical isolates of C. striatum, including our two cases, after exposure to daptomycin in broth culture, and seven isolates showed emergence of daptomycin resistance. To our knowledge, this is the first reported case of daptomycin-resistant C. striatum bacteremia in Japan. The use of daptomycin for the treatment of C. striatam infections should be avoided, considering the risk for rapid emergence of daptomycin resistance.

Over the last decade, many public institutions have emphasized the importance of antimicrobial stewardship (AS) in reducing the spread of antimicrobial resistance. In our facility, we have tackled AS that has adapted to clinical practices since 2015. In many facilities, especially university hospitals, multidrug-resistant bacteria, such as methicillin-resistant Staphylococcus aureus and extended-spectrum β-lactamase-producing bacteria, may cause infections. Considering this, we recommend prompt treatment with suitable antibiotics and dosage. In AS teams, pharmacists are responsible for administering pharmacotherapy, including optimal dosage for each patient. Therefore, they should assess their patients carefully, implement thorough therapeutic drug monitoring, and utilize the information obtained from these assessments to administer optimal pharmacotherapy. However, optimal pharmacotherapy also requires a correct diagnosis. Although diagnostic stewardship is not a pharmacist's work, it is a great opportunity for pharmacists to learn how expert physicians think. Based on the type of situation above, we train younger pharmacists on the job.
