New Antibiotics in the Management of Acute Bacterial Skin and Skin Structure Infections.

New Antibiotics in the Management of Acute Bacterial Skin and Skin Structure Infections. Skin Therapy Lett. 2015 Sep;20(5):7-9 Authors: Gleghorn K, Grimshaw E, Kelly EK Abstract Acute bacterial skin and skin-structure infections (ABSSSIs), often caused by aerobic gram-positive cocci, are most often mild-tomoderate infections that can easily be treated in an outpatient setting. With the rates of these infections substantially increasing in the past decade, owing in part to the emergence of community acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), alternative options for the treatment of ABSSSIs are necessary. This editorial reviews the mechanism of action, efficacy, bacterial coverage, and potential side effect profiles for dalbavancin and oritavancin, both semisynthetic lipoglycopeptide antibiotics, and tedizolid, an oxazolidinone. Dalbavancin, oritavancin, and tedizolid have been extremely valuable additions to treatment options for ABSSSIs due to the convenient dosing regimen and the fact that there are fewer resistant organisms to these therapies at this time.

In recent years, the management of bacterial infections in patients with cirrhosis has become increasingly complicated due to ...

Methicillin-resistant/susceptible Staphylococcus aureus (MRSA/MSSA) and Enterococcus faecalis strains are often found in community- and hospital-acquired infections. The single use of conventional antibiotics hardly completely kills the bacterial cells of interest, especially in the form of biofilms. Thus, drug repurposing and antimicrobial combination are promising ways to solve this problem. Antimicrobial susceptibility assays against cocci in a suspension and in a biofilm mode of growth were performed with broth microdilution methods. Checkerboard assays and the cutaneous mouse infection model were used to examine the a...

Abstract Patients with community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) pneumonia have poor clinical outcomes and high frequency of mortality, especially in patents with postinfluenza infection. Herein, we report a case of community-acquired pneumonia with multiple organ failure in a 51-year-old patient with initial presentation of flu-like symptoms. The influenza rapid test from the specimen of nasopharyngeal swab was positive for type B influenza virus and was confirmed by real-time polymerase chain reaction. Gram stain of bronchoalveolar lavage fluid revealed gram positive cocci in gro...

Conclusion and Relevance: This analysis of a large cohort of critically ill adults receiving empirical vancomycin found that Staphylococcus aureus was present in all but 15% of cases of MRSA-positive respiratory cultures after 48 hours, whereas Gram-positive cocci were identified within 48 hours during nearly all episodes of MRSA bacteremia. These findings may inform the timing of discontinuation of empirical vancomycin among critically ill adults. PMID: 31544471 [PubMed - as supplied by publisher]

We describe results from a multicenter study evaluating the Accelerate Pheno system, a first of its kind diagnostic system that rapidly identifies common bloodstream pathogens from positive blood cultures within 90 min and determines bacterial phenotypic antimicrobial susceptibility testing (AST) results within ~7 h. A combination of fresh clinical and seeded blood cultures were tested, and results from the Accelerate Pheno system were compared to Vitek 2 results for identification (ID) and broth microdilution or disk diffusion for AST. The Accelerate Pheno system accurately identified 14 common bacterial pathogens and two...

In conclusion, the efficacy of fosfomycin combinations, also confirmed in our in vivo model, may suggest new directions in the treatment of infected skin and a possible alternative way to control bacterial skin infection. PMID: 29154746 [PubMed - as supplied by publisher]

CONCLUSION: These results confirm the therapeutic versatility of our approach. However, to the extent that its synergistic efficacy is dependent on the ability to achieve both a lethal photothermal effect and the thermally-controlled release of a sufficient amount of antibiotic, they also demonstrate the importance of carefully designing appropriate antibody and antibiotic combinations to achieve the desired therapeutic synergy.

Conclusions These findings indicate that linezolid has an excellent activity against clinical drug resistant Gram-positive isolates in Iran. Constant monitoring and surveillance of linezolid MIC distribution allows the researchers to assess and detect gradual upward MIC drifts.
