SESSION TITLE Critical Care in Chest Infections Case Report Posters 2 SESSION TYPE Case Report Posters PRESENTED ON 10/17/2022 1215 pm - 0115 pm INTRODUCTION: Enterobacter species are notorious for causing nosocomial infection. They were found to be the third most common pathogen in the respiratory tract amongst isolates in the ICU. What makes the situation grim is the growing antibiotic resistance with regards to treating these infections. Such is the extent of this problem that in certain parts of the world the antibiotic sensitivity of Pluralibacter gergoviae is used as an indicator for the spreading antibiotic resistance in the environment. CASE PRESENTATION A 73 year old female with past medical history significant for hypertension, atrial fibrillation, and Coronary artery disease s/p stent placement in 2019 presented to our facility with a 4 day history of fever, cough and chest discomfort. She had tested positive for COVID-19 two days prior to presentation and was initiated on remdesivir, tocilizumab, and dexamethasone. She was initially managed on the floors but in view of her increasing oxygen requirement she was transferred to the critical care where she was intubated due to respiratory failure. She continued to spike fevers and was persistently hypoxic. Initially this was attributed to COVID pneumonia and a trial of convalescent plasma was also given. After 3 weeks, she tested negative for COVID-19 while still intubated and precautions were taken off. However, she continued to spike fevers. Repeat chest X-ray was done and it showed multifocal airspace disease with increasing opacification in the left upper lobe. Her endotracheal aspirate grew carbapenemase producing Pluralibacter gergoviae sensitive for ciprofloxacin. Subsequently, she was started on IV levofloxacin and received it for a total of 21 days. Her treatment course was complicated by prolonged intubation requiring tracheostomy and development of Pneumatocele. After stopping the antibiotics, she did not have fever and her white blood cell count was within normal limits. DISCUSSION: P. gergoviae is a known contaminant in intravenous fluids, invasive medical devices, eye cream, children's shampoo, skin cream, hand cleaning paste, and cleansing wipes. Over the decades due to selective pressure especially in the cosmetic industry from preservatives it has gained antibiotic resistance via overexpression of detoxifying enzymes, flagellin, modification of membrane structure/function. Improving patient's oral hygiene, implementing infection control protocols strictly in the ICU, minimizing invasive medical devices/catheters and educating the stakeholders shall help in curbing these incidents. Once identified, early Infectious disease specialist involvement can help choose an apt antibiotic regimen on the basis of existing antibiograms. CONCLUSIONS: This case highlighted the importance of close microbiological surveillance, minimizing occurrence of nosocomial infection and treating atypical organisms.
