Special Issue Information

Dear Colleagues,

Recently, international and domestic guidelines for appropriate selection and dosage of antimicrobial agents have undergone revision. A central component of its appropriate use is involved in pharmacokinetics/pharmacodynamics (PK/PD) theory. This theory considers the appropriate dosage and administration methods on the basis of the pharmacokinetics of drugs and the characteristics of each drug based on blood concentration of drugs; this information is used to determine the method of administration of antimicrobial agents. However, the PK/PD parameters such as area under the curve (AUC)/minimum inhibitory concentration (MIC), Cmax/MIC, and time above MIC need to be investigated since there is limited number of studies targeting patients with specific backgrounds. The absence of work is particularly marked with regard to patients receiving renal replacement therapy, children, elderly, and so on. In addition, despite huge difference in PK among infections, antibiotics are constant in dosage. Therefore, the ideal antibiotic strategy for use in these specific populations is controversial.

We welcome papers reporting original data from epidemiologic studies, as well as systematic reviews and meta analyses, especially those providing novel antibiotic strategies designed to overcome resistant pathogens in patients receiving renal replacement therapy.

Vancomycin or daptomycin is administered to hemodialysis patients infected with methicillin-resistant Staphylococcus and Enterococcus species. Although serious concerns regarding nephrotoxicity due to vancomycin have been raised, it might not be a critical issue in hemodialysis patients. Moreover, very few studies have investigated the effectiveness of vancomycin versus daptomycin in patients undergoing hemodialysis. Hence, we retrospectively evaluated the effectiveness and safety of vancomycin and daptomycin in patients undergoing hemodialysis. We investigated the following measures: mortality, clinical and microbiological effectiveness, and incidence of adverse events in hemodialysis patients who received vancomycin or daptomycin from 2014 to 2019. Moreover, we evaluated the covariates related to 30-day mortality. We found that 73 patients received vancomycin, while 34 received daptomycin for the treatment of infections due to methicillin-resistant Staphylococcus aureus, methicillin-resistant coagulase-negative Staphylococci, and Enterococcus faecium. Mortality after vancomycin treatment was significantly lower than daptomycin treatment (4.1% vs. 26.5%, p < 0.01). The clinical and microbiological effectiveness as well as the safety were not significantly different between the two treatments. Although daptomycin treatment with a loading dose was associated with lower mortality, the mortality of the treatment (8.3%) did not differ significantly compared to that of the vancomycin treatment (4.1%). Therefore, our findings suggest that vancomycin remains the first-line treatment for hemodialysis patients; however, a loading dose may be beneficial for patients receiving daptomycin. Full article
