Infectious Disease Frontier

As the global issue of antimicrobial resistance intensifies, newly emerging resistant bacterial strains pose a significant threat to public health. At the 34th European Congress of Clinical Microbiology and Infectious Diseases (ESCMID Global 2024), a study by Professor Ning Shen's team from Peking University Third Hospital (Abstract No.: E0451) focused on the resistance issues of cefiderocol, a drug not yet marketed in China. The study identified that cefiderocol can induce resistance and amplification of the blaSHV-12 gene in vitro. Long-read sequencing technology demonstrated its potential for rapid and accurate detection of resistance gene amplification, offering a new tool for future resistance research.

Despite ongoing developments in antimicrobial drugs and vaccines, the diagnosis of bacterial meningitis and viral encephalitis remains challenging due to their varied clinical presentations and is closely associated with high mortality rates. Traditional diagnostic methods have limitations, such as low positivity rates and lengthy processing times for cerebrospinal fluid (CSF) cultures, making early clinical diagnosis and treatment particularly difficult, especially in pediatric patients. At the 34th European Congress of Clinical Microbiology and Infectious Diseases (ESCMID Global 2024), a study by Professor Qing Cao's team from Shanghai Children's Medical Center affiliated with Shanghai Jiao Tong University School of Medicine, Professor Gang Liu's team from Beijing Children's Hospital affiliated with Capital Medical University, and Professor Haiyin Wang's team from Shanghai Municipal Health and Health Development Center was selected for an e-poster presentation. This study assessed the impact of the FilmArray Meningitis/Encephalitis Panel (FA-ME) on clinical outcomes and healthcare economics for pediatric patients.

Infective Endocarditis (IE) is a serious infectious cardiac condition. With advancements in medical technology, there have been significant changes in the diagnosis and treatment paradigms for IE. At the 34th European Congress of Clinical Microbiology & Infectious Diseases (ESCMID Global 2024), Infection Medicine Online had the privilege of interviewing Professor Maria Nazarena Pizzi from Vall d'Hebron University Hospital in Barcelona. Not only is Professor Pizzi a distinguished cardiologist, but she also participated in the update of the European Society of Cardiology (ESC) guidelines on endocarditis. In this interview, Professor Pizzi shared her expert insights on the updates to the 2023 ESC endocarditis guidelines, the application of imaging technologies, and the value of molecular diagnostic techniques

Prof. Etienne Ruppé, a professor of bacteriology at the Université Paris Cité and researcher at the IAME unit, is conducting a study on the impact of β-lactam antibiotics on the gut microbiota. His research primarily focuses on ceftriaxone, piperacillin-tazobactam, and ceftazidime-avibactam, uncovering significant findings regarding the differential impacts and lasting effects of these antibiotics on gut microbial communities. We interviewed Prof. Ruppé to discuss his research findings and their potential implications for antibiotic therapy and microbial health.

In the dynamic field of infectious diseases, guidelines must adapt to reflect ongoing research and technological advancements to ensure the highest standards of patient care. The 2023 European Society of Cardiology (ESC) Guidelines for the diagnosis of endocarditis mark a significant advancement in how clinicians approach this complex disease. To gain deeper insights into these important changes, Infectious Disease Frontier interviewed Dr. Maria Nazarena Pizzi, a leading cardiologist and expert in cardiac imaging at Vall d'Hebron University Hospital in Barcelona, Spain. Dr. Pizzi, with her extensive involvement in the development of these guidelines, shares her valuable perspective on their implications for clinical practice

Bloodstream infection (BSI) is a severe systemic infection, especially with multidrug-resistant bacteria such as carbapenem-resistant Gram-negative organisms (CRO), posing a significant threat to patient safety. Clinical management of BSI faces numerous challenges, with early diagnosis and precise treatment being crucial for improving patient outcomes. At the recent 34th European Congress of Clinical Microbiology and Infectious Diseases (ESCMID Global 2024), V. Anton-Vazquez and colleagues from St. George's University Hospital NHS Foundation Trust in the UK presented a study titled "Clinical Outcomes and Factors Associated with Optimal Antibiotic Therapy in Gram-Negative BSI: A Post Hoc Analysis of a Comparative Study between Rapid and Conventional Antimicrobial Susceptibility Testing." Infection Medicine has invited Professor Chongjie Pang  from Tianjin Medical University General Hospital to provide an in-depth commentary on this study, asking him to further elucidate its clinical significance and value based on his clinical experience.

Cefiderocol is a novel siderophore cephalosporin antibiotic with excellent stability against nearly all β-lactamases, including metalloenzymes. It has demonstrated good clinical efficacy against infections caused by carbapenem-resistant Gram-negative bacteria (CRO), garnering significant attention from experts in the field of infectious diseases. At the 34th European Congress of Clinical Microbiology and Infectious Diseases (ESCMID Global 2024), a multicenter, open-label randomized study (abstract number: O0810) compared the efficacy of cefiderocol with standard therapy in treating healthcare-associated and hospital-acquired Gram-negative bloodstream infections (BSI). "Infectious Disease Frontier" invited Professor YongHong Xiao from The First Affiliated Hospital of Zhejiang University School of Medicine to provide professional commentary on this study, analyzing the potential and prospects of cefiderocol in treating Gram-negative BSI.

Infection remains a major challenge for recipients of solid organ transplants (SOT), leading to serious risks of mortality and transplant failure. Previous research has primarily focused on the characteristics and prevention of infections within the first year post-surgery, with limited data on long-term infections beyond one year post-surgery. At the recent 34th European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Global 2024 Annual Meeting, a large-scale follow-up study from Switzerland reported that SOT recipients still face a high incidence of infections and disease burden beyond one year post-surgery.

From April 27th to 30th, 2024, the 34th European Congress of Clinical Microbiology and Infectious Diseases (ESCMID Global 2024) took place in Barcelona, Spain, known as the "Pearl of the Iberian Peninsula." ESCMID Global, formerly known as ECCMID, stands as one of the most influential international conferences in the field of infectious diseases. Often, clinical trials of antibiotics exclude special populations such as obese or underweight individuals, resulting in limited evidence for their treatment strategies. At this conference, several studies and advancements regarding antibiotic management and prescription, including interventions, monitoring, influences, decision support/predictive tools, and behavioral aspects, were reported. Below is a summary of the insights shared by Professor Wenxiang Huang from the Department of Geriatrics at The First Affiliated Hospital of Chongqing Medical University.

Editor's Note: Traditional microbiology laboratory methods such as Gram staining and antimicrobial susceptibility testing still rely on manual interpretation of results and report generation. The introduction of artificial intelligence (AI)…
