Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a frequent cause of orthopedic surgical site infections (SSIs). The aim of this study was to evaluate the effect of a bundle approach in the prevention of orthopedic MRSA SSIs.
Material and Methods: MRSA active surveillance and decolonization were performed preoperatively at our institution from July 2004 until 2007. In January 2008, a bundle approach comprising contact precautions for MRSA-positive patients and cefazolin-based antimicrobial prophylaxis (AMP) stewardship was implemented. Data on the prevalence of MRSA SSIs, antimicrobial use density, duration of AMP, and the use of an alcohol antiseptic agent (L/1,000 patient-days) were evaluated during 2 periods: July 2004-December 2007 (period A) and January 2008-December 2012 (period B).
Results and Discussion: The MRSA SSI rate during period B (0.97%; 19 out of 1,966) was significantly lower than that during period A (2.17%; 29 out of 1,333; P =.003). The infection rate correlated negatively with both the cefazolin antimicrobial use density (r = -0.76; P = .0002) and the use of an alcohol antiseptic agent (r = -0.68; P = .002).
Conclusions: An infection-prevention bundle consisting of contact precautions for carriers and AMP stewardship in addition to active surveillance was associated with a significant decrease in the incidence of orthopedic MRSA SSIs.

The immunomodulatory activity of linezolid has recently been reported using in vitro experimental models. However, the anti-inflammatory activity of linezolid has not yet been demonstrated using in vivo experimental models. Therefore, the aim of the present study was to demonstrate the anti-inflammatory activity of linezolid and other anti-MRSA agents using the carrageenan-induced rat paw edema model.The pretreatment with 50 mg/kg linezolid significantly suppressed edema rates, compared with control (5% glucose), with edema rates at 0.5 and 3 h after the administration of carrageenan being 17.3 ± 3.5 and 30.8 ± 3.0%, respectively. On the other hand, edema rates were not suppressed by the pretreatments with 50 mg/kg vancomycin, teicoplanin, arbekacin, and daptomycin. Furthermore, we demonstrated that linezolid exhibited anti-inflammatory activity in a concentration-dependent manner. These effects were observed at linezolid concentrations that are achievable in human serum with conventional dosing.In conclusion, the results of the present study suggest that the anti-inflammatory activities of linezolid, in addition to its antimicrobial effects, have a protective effect against destructive inflammatory responses in areas of inflammation.

Linezolid pharmacokinetic profile in pediatric patients has not been fully characterized, and the dose needed to achieve a pharmacokinetic-pharmacodynamic (PK-PD) target has yet to be established because its efficacy is associated with the area under the plasma drug concentration time curve (AUC(24))/minimum inhibitory concentration (MIC) ratio. The present study aimed to define the pharmacokinetic parameters of intravenous linezolid in pediatric patients and assess the rationale for the approved dosage recommendations. Linezolid was safe, tolerated well, and clinically effective for treating Gram-positive bacteria in five pediatric patients (3-11 years). The mean values for the volume of distribution, and total clearance (CL) in a one-compartment model were estimated to be 0.646 +/- 0.239 l/kg and 0.171 +/- 0.068 1/h/kg, respectively (mean +/- S.D.). Based on this analysis, the AUC(24) and trough drug concentration in plasma (C-min) for linezolid doses were predicted to be 175.4 mu g h/ml and 3.4 mu g/ml for 30 mg/kg/day, 204.7 mu g h/ml and 4.3 mu g/ml for 35 mg/kg/day, and 2632 mu g h/ml and 6.2 mu g/ml for 45 mg/kg/day, respectively. Taking into account that AUC(24) should be >= 200 mu g h/ml for MIC of 2.0 mu g/ml (to achieve an AUC(24)/MIC ratio of >= 100) and C-min should be approximately 7 mu g/ml (to avoid thrombocytopenia), we consider the approved dosage of 30 mg/kg/day to be fundamentally rational, but can be underdosed against bacteria with MIC of 2.0 mu g/ml; therefore, a dose of 35-45 mg/kg/day is more appropriate to ensure the efficacy and safety of linezolid in pediatric patients.

The antimicrobial agents vancomycin and metronidazole have been used to treat Clostridium difficile infections (CDIs). However, it remains unclear why patients are at risk of treatment failure and recurrence. Therefore, this study retrospectively examined 98 patients with CDIs who were diagnosed based on the detection of toxin-positive C. difficile to determine the risk factors affecting drug treatment responses and the recurrence of CDI. No significant difference was observed in the cure rate or dosage between the vancomycin and metronidazole groups. The 90-d mortality rate and total number of drugs associated with CDIs, including antiinfective agents used within 2 months before the detection of toxin-positive C. difficile, were significantly lower in the treatment success group than in the failure group. The total number of antiinfective agents and gastric acid-suppressive agents used during CDI therapy was also significantly lower in the success group than in the failure group. The period from the completion of CDI therapy to restarting the administration of anticancer agents and steroids was significantly longer in patients without than in patients with recurrence. These results indicate that the total number of drugs associated with CDIs should be minimized to reduce the risk of CDIs, that not only antibiotics but also gastric acid-suppressive agents should be discontinued during CDI therapy to increase therapeutic efficacy, and that the use of anticancer agents and steroids should be delayed as long as possible after patients are cured by CDI therapy to prevent recurrence.

The pharmacokinetic/pharmacodynamic (PK/PD) index for the efficacy of linezolid is a 24-h area under the plasma drug concentration-time curve (AUC(24))/minimum inhibitory concentration (MIC) ratio of >= 100. The main adverse event associated with administration of linezolid is thrombocytopenia. Therefore, the aims of the present study were to define PD thresholds that would minimise linezolid-induced thrombocytopenia and to perform a population PK analysis to identify factors influencing the pharmacokinetics of linezolid. Population PK analysis revealed that creatinine clearance (CLCr) significantly affected linezolid pharmacokinetics: the mean parameter estimate of drug clearance (CL; in L/h)= 0.0258 x CLCr + 2.03. A strong correlation (r=0.970) was found between AUC(24) and trough plasma concentrations (C.) [AUC(24)=18.2 x C-min + 134.4]. The Cmin value for AUC(24)=200 (in the case of MIC=2 mu g/mL) was estimated to be 3.6 mu g/mL. Regarding safety, Cmin was a significant predictor of thrombocytopenia during treatment, and its threshold to minimise linezolid-induced thrombocytopenia was 8.2 mu g/mL. A Kaplan-Meier plot revealed that the median time from initiation of therapy to the development of thrombocytopenia was 15 days. Therefore, the target C. range was 3.6-8.2 mu g/mL. The following formula to achieve a target C. in patients with different degrees of renal function was proposed based on these results: initial daily dose (mg/day) = CL x AUC(24) = (0.0258 x CLCr + 2.03) x (18.2 x C-min + 134.4). This recommended initial dosage and subsequent dosage adjustment for the target concentration range should avoid adverse events, thereby enabling effective linezolid-based therapies to be continued.

Arbekacin (ABK) was approved and widely used in Japan for treatment of patients infected with MRSA, and TDM was introduced in clinical practice. The Japanese Society of Chemotherapy and the Japanese Society of Therapeutic Drug Monitoring decided to develop a clinical practice guidelines for TDM of ABK for the following reasons. First, although the daily dose of 150-200 mg was approved in Japan, recent PR-PD studies revealed that higher serum concentration is required to achieve better clinical efficacy and several findings concerning the usefulness of higher dosage regimen have obtained recently. Second, although maximal concentrations that obtained immediately after the end of administration (C-max) was generally adopted, the serum concentration at 1 h after initiation of administration [peak serum concentration (C-peak)] proved to be more suitable as an efficacy indicator of aminoglycosides. Lastly, as ABK is approved only in Japan, no international practice guideline for TDM has not been available in ABK to date. This guideline evaluated the scientific data associated with serum ABK monitoring and provided recommendations based on the available evidence. Potential limitations of this guideline, however, include the findings that few prospective clinical trials of TDM of ABK are available in the treatment of MRSA infections and that most of the published literature describes observational studies.
