Abstract
BACKGROUND We aimed to determine whether daptomycin plus fosfomycin provides higher treatment success than daptomycin alone for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and endocarditis. METHODS A randomized (1:1) phase 3 superiority, open-label, and parallel group clinical trial of adult inpatients with MRSA bacteremia was conducted at 18 Spanish hospitals. Patients were randomly assigned to receive either 10 mg/kg of daptomycin intravenously daily plus 2 g of fosfomycin intravenously every 6 hours, or 10 mg/kg of daptomycin intravenously daily. Primary endpoint was treatment success 6 weeks after the end of therapy. RESULTS Of 167 patients randomized, 155 completed the trial and were assessed for the primary endpoint. Treatment success at 6 weeks after the end of therapy was achieved in 40 of 74 patients who received daptomycin plus fosfomycin and in 34 of 81 patients who were given daptomycin alone (54.1% vs 42.0%; relative risk, 1.29 [95% confidence interval, .93-1.8]; P = .135). At 6 weeks, daptomycin plus fosfomycin was associated with lower microbiologic failure (0 vs 9 patients; P = .003) and lower complicated bacteremia (16.2% vs 32.1%; P = .022). Adverse events leading to treatment discontinuation occurred in 13 of 74 patients (17.6%) receiving daptomycin plus fosfomycin, and in 4 of 81 patients (4.9%) receiving daptomycin alone (P = .018). CONCLUSIONS Daptomycin plus fosfomycin provided 12% higher rate of treatment success than daptomycin alone, but this difference did not reach statistical significance. This antibiotic combination prevented microbiological failure and complicated bacteremia, but it was more often associated with adverse events. CLINICAL TRIALS REGISTRATION NCT01898338.

Long-term endemic situation caused by a linezolid- and meticillin-resistant clone of Staphylococcus epidermidis in a tertiary hospital. J Hosp Infect 2019; 105:64-69.

Abstract
BACKGROUND Linezolid (LZD)-resistant Staphylococcus epidermidis (LRSE) are increasing, and are mainly associated with outbreaks in hospital wards with high LZD consumption. AIM To investigate the frequency of LRSE in a tertiary hospital in the context of LZD use. METHODS The frequency of LRSE and the data on LZD usage [expressed as defined daily dose (DDD) per 100 patient-days], from 2011 to 2017, were analysed retrospectively. Selected LRSE were typed by pulsed-field gel electrophoresis (PFGE) and screened for transferable LZD resistance genes. Representative isolates were typed by multi-locus sequence typing, and ribosomal mechanisms of LZD resistance were investigated. FINDINGS In total, 435 LRSE were detected, with frequencies ranging from 13.56% to 32.93% in the intensive care unit (ICU) where LZD consumption was high (6.34-8.10 DDDs), and from 2.48 to 6.80% in the remaining wards where LZD use was considerably lower (0.63-2.49 DDDs). The first 44 LRSE isolates recovered (June 2013-June 2014) were closely related according to PFGE patterns, and all except one were resistant to meticillin due to mecA production. Selected isolates belonged to ST2, carried SCCmec III, and had the G2576T mutation in the V domain of each of the six copies of the 23S rRNA gene. Five of the 44 isolates (11.36%) were positive for the cfr gene. CONCLUSION An ST2 LZD- and meticillin-resistant clone was found in the ICU and also in wards with low consumption of LZD. This highlights the need to implement and maintain infection control measures as well as antimicrobial stewardship programmes in all hospital units in order to preserve the efficacy of LZD.
