INTRODUCTION: Cardiovascular compromise in coronavirus disease 2019 (COVID-19) does not necessarily present with the classic symptoms described in myocarditis. There is growing evidence demonstrating subclinical cardiovascular compromise in the context of the intense inflammation unleashed, the cytokine storm involved, the baseline prothrombotic state, and the consequent endothelial dysfunction. We set out to analyse whether Troponin-T (TT) and the amino-terminal fraction of pro-brain natriuretic peptide (NT-proBNP) determined at hospital admission, are related to mortality during the hospitalization of these patients. MATERIAL AND METHODS: Analytical, observational, retrospective cohort and cross-sectional study. It included subjects with COVID-19 hospitalized for moderate-severe illness, from 20/03/20 to 15/11/20. The TT and NT-proBNP obtained in the first 24 hours from admission were analysed. Altered TT was considered if ≥.014 ng/dl and altered NT-proBNP if ≥300 pg/ml. RESULTS: One hundred and eight subjects were included, 63.2% men, age 51.5 years (59-43), 28% were admitted to the Critical Unit and 25% died. The group with elevated TT presented higher mortality (OR = 3.1; 95%CI = 1.10-8.85; p = .02). The group with elevated NT-proBNP also show higher mortality (OR = 3.47; 95%CI = 1.21-9.97; p = .01). On multivariate analysis, only NT-proBNP ≥300 pg/ml remained an independent risk factor. CONCLUSIONS: NT-proBNP levels ≥300 pg/ml at admission in patients with moderate-severe COVID-19 were associated with higher mortality.

Background. Patients with severe SARS-CoV-2 infection are at high risk of complications due to the intensive care unit stay. Hospital-acquired infections (HAI) are one of the most common complication and cause of death in this group of patients, it is important to know the epidemiology and microbiology of this hospital-acquired infections in order to begin to the patients a proper empirical treatment. We describe the epidemiologic and microbiologic characteristics of HAI in patients with COVID-19 hospitalized at intensive care unit (ICU) in a tertiary level private hospital in Mexico City. Methods. From April to December 2020, data from all HAIs in patients with severe pneumonia due to SARS-CoV-2 infection with mechanical ventilation at ICU were obtained. The type of infection, microorganisms and antimicrobial susceptibility patterns were determined. Results. A total of 61 episodes of HAIs were obtained, the most common was ventilator associated pneumonia (VAP) in 52.4% (n=32) followed by urinary tract infection (UTI) 34.4%(n=21) and bloodstream infection (BSI) 9.84% (n=6). Only two episodes corresponded to C. difficile associated diarrhea. We identified 82 different microorganisms, the most frequent cause of VAP was P. aeruginosa 22% (10/45) followed by K. pneumoniae 20% (9/45);for UTI, E. coli 28.5% (6/21), and S. marcescens 19% (4/21);for BSI the most frequent microorganism was S. aureus 28.5 (2/7). Regarding the antimicrobial susceptibility patters the most common were Extended Spectrum Beta-Lactamase (ESBL) Gram-negative rods followed by Methicillinresistant Staphylococcus aureus. Conclusion. In patients with severe COVID-19 hospitalized in the ICU the most frequent HAIs were VAP and UTI caused by P. aeruginosa and E. coli respectively. ESBL enterobacteriaceae was the most common resistant pattern identifed in the bacterial isolations in our series.
