Intensive care unit (ICU) patients are at risk of developing serious infections with multidrug-resistant organisms (MDROs), which require appropriate and adequate antibiotic coverage. Early empirical coverage is pivotal in saving patients’ lives. At a recent webinar co-organized by the Society of Infectious Disease (Singapore) and Pfizer, renowned Professor David Paterson, Professor of Medicine and Director, The University of Queensland Centre for Clinical Research, and Consultant Infectious Diseases Physician, Royal Brisbane and Women’s Hospital, Brisbane, Australia, discussed the role of newer antimicrobial agents, including ceftazidime-avibactam (Zavicefta) in the management of MDROs in the ICU. Dr Wong Sin Yew, Infectious Disease Physician at Gleneagles Medical Centre and Mount Elizabeth Novena Specialist Centre, Singapore, chaired the event.
The rising incidence of infections caused by multidrug-resistant (MDR) gram-negative bacteria has become a serious health threat and a major challenge for intensivists. Against a backdrop of high patient mortality and risk factors for infection in intensive care units (ICU), early adequate therapy is of paramount importance. At a recent Pfizer-sponsored symposium, Dr Asok Kurup, Infectious Disease Physician, Singapore presented the implications of MDR gram-negative infections in critically ill patients in Asia, while Dr Kenneth Chan, Respiratory Physician and Intensivist, Singapore highlighted the role of ceftazidime-avibactam (Zavicefta) and shared published real-world data on ceftazidime-avibactam.
As the COVID-19 pandemic continues to spread around the globe, comparison is often drawn to influenza, another contagious respiratory-borne disease. Recently, Dr Azureen Azmel, a consultant infectious disease physician at Hospital Tengku Ampuan Rahimah (HTAR), and Dr Leong Chee Loon, a consultant infectious disease physician with Hospital Kuala Lumpur (HKL), came together to discuss about the importance of annual influenza vaccination during the current COVID-19 pandemic.
Oral H1-antihistamines are the initial treatment of choice for allergic rhinitis (AR) and chronic urticaria in the primary care setting. However, in a diverse population of patients with AR and urticaria, primary care physicians are faced with the challenge of prescribing the best therapy amid a wide armamentarium of antihistamines available.
Macrolide antibiotics are derived from the Streptomycesspecies. These contain either 14-membered (erythromycin [ERM],clarithromycin [CAM], roxithromycin [RXM]), 15-membered(azithromycin [AZM]) or 16-membered (spiramycin, josamycin,midecamycin) macrocyclic lactone rings. They inhibit proteinsynthesis by reversibly binding to the 23S ribosomal RNA (rRNA)in the 50s subunit of the bacterial ribosome. Traditionally,macrolides are used as first-line agents in respiratory, skin,soft tissue, and urogenital infections, and they are also activeagainst gram-positive cocci and atypical pathogens.
Pneumonia is a common infection– affecting around 3,200 people inSingapore in 2016 – making it the thirdmost common cause of hospitalisation inthe country. Its common complications,especially with delayed or inappropriatetreatment, include bacteraemia andseptic shock, lung abscesses, pleuraleffusions, empyema, pleurisy, respiratoryfailure and renal failure.
