  • Susceptibility Testing for Aztreonam with Ceftazidime-Avibactam

    13/07/2023 Duração: 38min

    The combination of aztreonam with ceftazidime-avibactam is increasingly used for treatment of antimicrobial-resistant Gram-negative bacilli. Clinical laboratories are asked to perform susceptibility testing using this combination, but many laboratory directors have been unsure how to approach this. Today, we’ll discuss a recent paper in the Journal of Clinical Microbiology in which the investigators evaluated a promising method for testing this combination of two antimicrobials and a beta-lactamase inhibitor. We will also discuss the rational for combining these agents, as well as what lab directors should consider before validating and offering this susceptibility testing.   Guests: Dr. Trish Simner - Director of the Medical Bacteriology and Infectious Disease Sequencing Laboratories, Johns Hopkins Hospital Dr. Romney Humphries - Director of the Division of Laboratory Medicine and the Medical Director of the Microbiology Laboratory at Vanderbilt University Medical Center.

  • Susceptibility Testing for Piperacillin-Tazobactam (JCM ed.)

    08/04/2023 Duração: 49min

    Susceptibility testing for piperacillin-tazobactam has undergone rapid evolution, largely driven by some surprising results from the MERINO trial, which compared the efficacy of piperacillin-tazobactam and meropenem for treatment of patients with ceftriaxone-resistant E. coli or Klebsiella pneumoniae bacteremia. We discuss how the results of the MERINO trial led to reconsideration of breakpoints for pipercillin-tazobactam at the Clinical Laboratory Standards Institute, or CLSI, how the breakpoints were changed, and how well commercial platforms perform piperacillin-tazobactam testing using FDA or CLSI breakpoints. Spoiler alert: the news isn’t great. If you are interested in beta-lactam/beta lactamase combinations, you should check out the previous episode of this podcast, hosted by our friend Dr. Cesar Arias, the Editor-in-Chief of Antimicrobial Agents and Chemotherapy. Cesar and the guests did a great review of recent developments in this fast-moving area. Guests: Dr. Trish Simner - Director of the Medica

  • Avoiding HIV False Positives (JCM ed.)

    24/02/2023 Duração: 29min

    e can probably all agree that any false positive test result is bad, but I think it’s safe to say that some false positives, like a false positive HIV test for example, is much more anxiety provoking than others. And when it comes to HIV, there have been a number of key advances in the field over the past decade, include the development of improved diagnostics and optimized algorithmic approaches, all of which have allowed for earlier detection of infected patients, and particularly those with acute HIV. Among these advancements has been the development of 4th and 5th generation serologic assays, which offer multiple benefits over prior assay versions, but unfortunately, are not immune to the possibility of false positive results. So, confirmatory test remain a necessary – the challenge though is that depending on the institution and environment, the turnaround time for such confirmatory testing can be prolonged, leaving patients and clinicians in a kind of diagnostic limbo. So, is there a way to minimize the

  • Molecular Testing for Periprosthetic Joint Infections (JCM ed.)

    14/01/2023 Duração: 38min

    The applications of large multiplex panels for detection of pathogens have greatly expanded in the past several years. Initial tests were for detection of respiratory viruses, and the first such test was labor intensive and vulnerable to frequent contamination. Since then, additional sample types have been added, such as cerebrospinal fluid and positive blood culture broths, and tests are easier to perform and reasonably reliable. We discuss a research use only multiplex PCR assay for detection of pathogens in joint infections, and learning how it compares to targeted metagenomic sequencing and culture for detection of pathogens in periprosthetic joint infections. Guests: Dr. Marisa Azad - Assistant Professor of Medicine in the Division of Infectious Diseases at The Ottawa Hospital and an Associate Clinical Scientist at the Ottawa Hospital Research Institute.

  • The Best Clinical Microbiology Papers of 2022 (JCM Ed.)

    07/12/2022 Duração: 01h06min

    As we enter into the holiday season, many of us look forward to celebrating long-standing traditions with family and friends, which is no different from us here on the podcast! While not necessarily as long-standing as some of the other classic holiday traditions, after 2.5 years on air, we on this podcast have established our own end-of-year tradition, which is to take a look back at some of our favorite papers or more intriguing manuscripts published in the Journal of Clinical Microbiology over the past year. And so as you’ll see, thanks to the different areas of expertise and general interest among our panel today, we’ve selected quite a variety of papers to discuss, ranging from evaluation of new blood culture systems to use of metagenomics for infective endocarditis and to the potential application of interferon gamma release assays for detection of Histoplasma infections. And so, suffice it to say, there will be something of interest for everyone listening. But, for those watching today, you are clearly

  • How Can Clinical Microbiology Labs Contribute to Antimicrobial Stewardship? (JCM ed.)

    18/11/2022 Duração: 42min

    Deciding how extensively to work up and report respiratory cultures is the worst. There are useful guidelines on how to approach this. But, in my experience, very few laboratories strictly follow these guidelines. That can be because of concerns about under-reporting pathogens or about over-reporting microbiota, or it can be the result of pressure from clinical staff to report more organisms than the guidelines suggest. Today, we’ll be talking with two guests about their study on how over-reporting of organisms from respiratory tract cultures can lead to over treatment with antimicrobials. Guests: Dr. Sarah Parker, pediatric infectious disease specialist at Children’s Hospital Colorado and the Medical Director of the Antimicrobial Stewardship Program. Dr. Andrea Prinzi, infectious disease medical science liason with bioMerieux.

  • How Proposed Change to US Regulation Could Impact Clinical Microbiology Labs

    16/09/2022 Duração: 51min

    There are a number of regulatory proposals under consideration which could have important effects on clinical microbiology labs, and clinical labs more generally. First, the VALID act would change how clinical tests are regulated with particularly important implications for laboratory-developed tests. Second, the Centers for Medicare and Medicaid Services has proposed changes to the educational requirements for lab directors under CLIA and additional changes that would increase the fees that clinical labs pay to CMS. If you have been waiting for someone to explain these changes and how they could affect your lab, you’ve come to the right podcast.

  • The Inoculum Effect of Antibiotic Susceptibility Testing

    20/08/2022 Duração: 25min

    The inoculum effect of antibiotic susceptibility testing is often discussed at playgrounds and infectious diseases conferences, but many of us don’t really have a clear definition of what it is or a good understanding of its importance. We’ll be talking about the inoculum effect and susceptibility testing of Staphylococcus aureus with cefazolin. Some of the questions we’ll discuss are: • What exactly is the inoculum effect and how is it measured? • Does the inoculum effect have clinical significance? • How common is the inoculum effect with Staph aureus and cefazolin?
