  • Comparison of Arbekacin and Vancomycin in Treatment of Chronic Suppurative Otitis Media by Methicillin Resistant Staphylococcus Aureus
    ORIGINAL ARTICLE Infectious Diseases, Microbiology & Parasitology http://dx.doi.org/10.3346/jkms.2015.30.6.688 • J Korean Med Sci 2015; 30: 688-693 Comparison of Arbekacin and Vancomycin in Treatment of Chronic Suppurative Otitis Media by Methicillin Resistant Staphylococcus aureus Ji-Hee Hwang,1 Ju-Hyung Lee,2,4 Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of ear infections. We Jeong-Hwan Hwang,3 Kyung Min Chung,5 attempted to evaluate the clinical usefulness of arbekacin in treating chronic suppurative Eun-Jung Lee,6 Yong-Joo Yoon,4,6 otitis media (CSOM) by comparing its clinical efficacy and toxicity with those of Mi-Kyoung Moon,1 Ju-Sin Kim,1 vancomycin. Efficacy was classified according to bacterial elimination or bacteriologic 1 3,4 Kyoung-Suk Won, and Chang-Seop Lee failure and improved or failed clinical efficacy response. Ninety-five subjects were diagnosed with CSOM caused by MRSA. Twenty of these subjects were treated with 1Department of Pharmacy, Chonbuk National University Hospital, Jeonju; Departments of arbekacin, and 36 with vancomycin. The bacteriological efficacy (bacterial elimination, 2Preventive Medicine and 3Internal Medicine, arbekacin vs. vancomycin: 85.0% vs. 97.2%) and improved clinical efficacy (arbekacin vs. Chonbuk National University Medical School, vancomycin; 90.0% vs. 97.2%) were not different between the two groups. However, the 4 Jeonju; Research Institute of Clinical Medicine of rate of complications was higher in the vancomycin group (33.3%) than in the arbekacin Chonbuk National University-Chonbuk National University Hospital, Jeonju; Departments of group (5.0%) (P = 0.020). In addition, a total of 12 adverse reactions were observed in the 5Microbiology & Immunology, and 6Otolaryngology- vancomycin group; two for hepatotoxicity, one for nephrotoxicity, eight for leukopenia, Head and Neck Surgery, Chonbuk National two for skin rash, and one for drug fever.

  • Candida Auris
    microorganisms Review Candida auris: Epidemiology, Diagnosis, Pathogenesis, Antifungal Susceptibility, and Infection Control Measures to Combat the Spread of Infections in Healthcare Facilities Suhail Ahmad * and Wadha Alfouzan Department of Microbiology, Faculty of Medicine, Kuwait University, P.O. Box 24923, Safat 13110, Kuwait; [email protected] * Correspondence: [email protected]; Tel.: +965-2463-6503 Abstract: Candida auris, a recently recognized, often multidrug-resistant yeast, has become a sig- nificant fungal pathogen due to its ability to cause invasive infections and outbreaks in healthcare facilities which have been difficult to control and treat. The extraordinary abilities of C. auris to easily contaminate the environment around colonized patients and persist for long periods have recently re- sulted in major outbreaks in many countries. C. auris resists elimination by robust cleaning and other decontamination procedures, likely due to the formation of ‘dry’ biofilms. Susceptible hospitalized patients, particularly those with multiple comorbidities in intensive care settings, acquire C. auris rather easily from close contact with C. auris-infected patients, their environment, or the equipment used on colonized patients, often with fatal consequences. This review highlights the lessons learned from recent studies on the epidemiology, diagnosis, pathogenesis, susceptibility, and molecular basis of resistance to antifungal drugs and infection control measures to combat the spread of C. auris Citation: Ahmad, S.; Alfouzan, W. Candida auris: Epidemiology, infections in healthcare facilities. Particular emphasis is given to interventions aiming to prevent new Diagnosis, Pathogenesis, Antifungal infections in healthcare facilities, including the screening of susceptible patients for colonization; the Susceptibility, and Infection Control cleaning and decontamination of the environment, equipment, and colonized patients; and successful Measures to Combat the Spread of approaches to identify and treat infected patients, particularly during outbreaks.

  • Double Stage Activity in Aminoglycoside Antibiotics
    VOL.53 NO. 10, OCT.2000 THE JOURNAL OF ANTIBIOTICS pp.1168 - 1174 Double Stage Activity in Aminoglycoside Antibiotics Kunimoto Hotta, Atsuko Sunada, Yoko Ikeda1" and Shinichi Kondo1" National Institute of Infectious Diseases, 1-23-1 Toyama, Shinjuku-ku, Tokyo 162-8640, Japan f Institute of Microbial Chemistry, 3-14-23 Kamiosaki, Shinagawa-ku, Tokyo 141-0021, Japan (Received for publication July 5, 2000) Fourteen different aminoglycoside antibiotics (AGs) were challenged with aminoglycoside acetyltransferases (AACs) of actinomycete origin in order to examine their 'double stage activity' that is arbitrarily defined as antibiotic activity retainable after enzymatic modification. In kanamycin (KM)-group AGs tested [KM, dibekacin (DKB), amikacin and arbekacin (ABK)], ABKretained activity after acetylations by AAC(3), AAC(2') and AAC(6'). DKBalso retained a weak activity after acetylation by AAC(2'). In gentamicin (GM)-group AGs tested [GM, micronomicin, sisomicin (SISO), netilmicin (NTL) and isepamicin], GM, SISO and NTL retained activites after acetylation by AAC(2'). In neomycin (NM)-group AGs tested [ribostamycin, NM,paromomycin], NMretained activity after acetylation by AAC(6') and AAC(2'). None of astromicin (ASTM)-group AGs tested (ASTMand istamycin B) retained activity after acetylation by AAC(2') and AAC(6'). The activities of acetylated ABK derivatives by AAC(3) and AAC(2') were distinctively high, compared to the others. Streptomyces lividans TK21containing the cloned aac genes were markedly sensitive to AGs that retained activities after acetylation, indicating the substantial effect of 'double stage activity'. Aminoglycoside (AG) antibiotics are generally resistant bacteria was developed by introducing (S)-4- inactivated by acetylation, phosphorylation and adenylyl- amino-2-hydroxybutyryl (AHB) side chain at 1-NH2 of ation due to AG acetyltransferases (AACs), AG KM.
