ABSTRACT
Aim of this study is to evaluate the incidence of fungal infections in COVID-19 intensive care unit (ICU) patients, to identify potential risk factors and to investigate whether differences in patients' outcomes are depicted. Material-Methods: This prospective observational study included critically ill patients diagnosed with COVID-19 that were admitted from 1/9/2020 to 1/11/2021 in ICU of the 1st Respiratory Department of Sotiria Chest Diseases Hospital. Epidemiologic characteristics, severity of disease, medication, outcome and complications were recorded. Result(s): Out of 300 patients included (213 men, 60,4+/-13,23 (mean+/-SD) years-old), 22 (7,3%) developed fungal infections (16 COVID-19 Associated Pulmonary Aspergillosis, 5 COVID-19 Associated Candidemia and 1 both). They were 6 female & 16 male, 55,73+/-13,28 years-old. Most patients had co-infections with multi-drug resistant bacteria. Patients with fungal infections were statistifically more on high dose of corticosteroids, invasive mechanical ventilation and renal replacement treatment (p<0.05). They had statistically more positive blood and bronchial secretion cultures, as well as more incidents of septic shock, venous thromboembolism and varotrauma (p<0.05). Their PaO2/FiO2 ratio on admission was statistically lower (p<0.05). Finally, after adjustment for confounfing factors and ICU days, they were at higher risk of dying (50% mortality). Conclusion(s): Fungal infections are a significant co-infection in critically ill COVID-19 patients. Those patients seem to have more severe respiratory failure on admission, be on higher doses of corticosteroids and in need of organ failure support. They also seem to develop more complications of COVID-19 and be at a higher risk of dying.
ABSTRACT
Background. Bacterial co-infections in COVID-19 patients represent a significant challenge for clinicians and can impact outcomes. Rapid identification of bacterial co-pathogens improves management, and is crucial to avoid inappropriately administered antimicrobials. We evaluated the use of a multiplex PCR assay in the early detection of respiratory co-infections in COVID-19 hospitalized patients. Methods. The study included non-ICU patients with high clinical suspicion of respiratory co-infection. Lower respiratory tract samples (sputum/bronchial secretions), were analyzed using BIOFIRE FILMARRAY pneumonia panel plus [(bioMerieux, USA), FA]. Specimens were considered as acceptable based on Gram stain. Conventional cultures were also performed. Results. A total of 28 samples from 27 patients (20 males, median age 60 years, IQR 49-71) were analyzed. 8/27 patients were intubated, 5 were treated with high flow nasal canula oxygenation and 11 with high or low oxygen mask. 18 patients received dexamethasone. Co-infection was detected in 17/27 patients (62.9%). 11 specimens were collected in less than 48 hours from admission and no target was identified in 6/11. Detected pathogens and AMR genes, per sample tested, are presented in the table. Bacterial pathogens and any AMR genes were detected in 15 and 4 samples, respectively, leading to modifications of antimicrobial treatment. The semi-quantitative results along with patients' clinical presentation assisted with differentiation of bacterial colonization versus infection, especially in cases where multiple targets were identified. De-escalation was implemented for 12 patients, for whom no co-infection or a viral co-pathogen (n=2) was detected. One patient was co-infected with another Coronavirus;further analysis, using the FA respiratory panel, detected Human coronavirus HKU-1 along with SARS-CoV-2. Median time until discharge or death was 13.5 days (IQR 9-24). Overall mortality was 33.3%. Detected pathogens, microbial load and AMR genes, per sample tested. Conclusion. Implementation of FA assay proved effective for the rapid detection of respiratory co-infections in COVID-19 non-ICU patients. Molecular panel-based assays can contribute to timely adaptation of antimicrobial treatment, benefiting patient management and antibiotic stewardship strategies.
ABSTRACT
SESSION TITLE: Post-COVID-19 Infection Complications SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: We present two cases of symptomatic post-COVID eosinophilic pneumonia responsive to steroids. CASE PRESENTATION: Case 1: A 73-year-old gentleman with underlying asymptomatic rheumatoid arthritis (RA), was admitted with COVID pneumonia for which he received tocilizumab, remdesivir, and 12 days of dexamethasone. His course was complicated by MRSA pneumonia and bacteremia, so was discharged on IV Vancomycin. Six days post discharge, he redeveloped respiratory distress. Labs showed a WBC 18,000 and proBNP 2828. A chest CT revealed bilateral ground-glass opacities, worsening right upper lung airspace disease and bilateral pleural effusions. Despite receiving Furosemide, Vancomycin, and Ceftazidime, he required high-flow nasal cannula oxygenation (HFNC). Bronchoscopy demonstrated thick right bronchial secretions. BAL fluid revealed 7% eosinophils and grew MRSA. Case 2: A 70-year-old gentleman with extensive smoking history, emphysema, psoriasis, Guillain-Barré syndrome and a recent hospitalization for COVID pneumonia was discharged on a steroid taper. He returned 23 days post discharge in respiratory distress requiring HFNC, 5 days after discontinuing steroids. The chest CT revealed worsening fibrosis and bronchiectasis. Intravenous Levofloxacin and Vancomycin resulted in no clinical improvement. Bronchoscopy showed inflamed bronchi with secretions and BAL analysis revealed 6% eosinophils. For both patients, BAL was negative for fungi and PJP and CTA ruled out PE. Both patients were started on Prednisone with a prolonged taper. They improved clinically with decreased oxygen requirements to 4L nasal cannula and dramatic decrease in subjective dyspnea within 48 hours of starting steroids. DISCUSSION: The differential diagnosis for the clinical deterioration and worsening radiographs in both patients includes bacterial/fungal superinfection, PE, post-COVID-ILD and eosinophilic pneumonia. For the first patient, his RA was inactive. His BAL was positive for MRSA but did not improve until steroids were initiated. Neither of the patients were stable for VATS biopsy. Eosinophilic pneumonia is defined as pulmonary infiltrates with peripheral blood eosinophilia =500/ml, BAL eosinophils > 5% or eosinophilic infiltration on lung biopsy [1]. Both of our patients had >5% BAL eosinophils. Potentially, prolonged COVID-ILD stimulates T-Helper-2 cells, causing the release of IL-4/5/13 with recruitment of eosinophils. Studies report post-COVID-ILD biopsies show organizing pneumonia and fibrosis but have not yet been associated with eosinophilia. In both patients, we observed eosinophilia on BAL. It can be hypothesized that a delayed inflammatory response mediated by eosinophils play a role. CONCLUSIONS: Pulmonary eosinophilic pneumonia is a complication of post-COVID-ILD and can be successfully managed with steroids. Reference #1: De Giacomi F, Vassallo R, Yi ES, Ryu JH.

ABSTRACT
We report a rare case of a patient who presented in our department with a ruptured 7,5cm infrarenal abdominal aortic aneurysm. The patient was hemodynamically unstable, and we proceeded immediately with an open repair procedure with successful result. Rapid antigen test for COVID-19 was negative but one day after the PCR test from bronchial secretions turned positive. Fortunately, no transmission of the disease was noted. Rapid antigen test result is insufficient and full protective measures should be implemented in all emergent situations to avoid COVID-19 spread.
