We report a case of false-negative SARS-CoV-2 reverse transcriptase-polymerase chain reaction (RT-PCR) on a nasopharyngeal swab. Treating clinicians and infection preventionists should maintain a high suspicion for COVID-19 in the appropriate clinical setting despite negative test results. Utilization of chest computed tomography (CT) should be strongly considered in the diagnostic work-up for suspected COVID-19, particularly in areas with limited RT-PCR availability.

A 60-year-old male presented to the emergency department (ED) with a 1–2 day history of confusion, headache, and subjective fever. Because he had met with a contact two days prior to admission who had recently traveled from the Bahamas, a COVID-19 nasopharyngeal (NP) and oropharyngeal (OP) polymerase chain reaction (PCR) test was ordered. He was diagnosed with bacterial meningitis based on presenting neurologic symptoms and the identification of Streptococcus pneumoniae from blood cultures. The COVID-19 NP and OP test returned positive, although he never developed shortness of breath, cough, other respiratory symptoms, diarrhea, abdominal pain, nausea, vomiting, or any change …

The University of Louisville Journal of Respiratory Infections
Background: One weakness that applies to all population-based studies performed in the United States (US) is that investigators perform population-based extrapolations without providing objective statistical evidence to show how well a particular city is a suitable surrogate for the US. The objective of this study was to propose and utilize a novel computational metric to compare individual US cities with the US average.
Methods: This was a secondary data analysis of publicly available databases containing US sociodemographic, economic, and health-related data. In total, 58 demographic, housing, economic, health behavior, and health status variables for each US city with a residential …

Patients with COVID-19 may have co-infections with other microorganisms. Here we report a case of a patient with an Escheria coli bacteremia secondary to a urinary tract infection, who experienced fevers while on active antimicrobial therapy. The patient was eventually tested for COVID-19 and found to be positive. This case emphasizes the need to suspect COVID-19 even in patients with documented bacterial infection.

The novelty and uncertainty associated with COVID-19 has created challenges for politicians, citizens, and healthcare providers, leaving no one unaffected. As members of the front line of defense, providers in Emergency Departments (EDs) face the momentous challenge of effectively identifying and treating patients with COVID-19, working with experts in Infectious Disease, Internal Medicine, Critical Care, Public Health, and other disciplines. We must coordinate these efforts while also protecting staff, implementing strategies to reduce transmission, and managing ED patients with conditions unrelated to COVID-19. Striving to maintain a grasp of the rapidly accumulating publications in medical journals and the media, we …

Abo Blood Group Type And Susceptibility To Covid-19 Infection, G. Rafael Fernandez-Botran
The University of Louisville Journal of Respiratory Infections
Since December 2019, the SARS-CoV-2 (COVID-19) pandemic has extended its reach over most of the world, infecting over four million people and causing well over 300,000 deaths so far.[1] A significant percentage of infected patients develop severe symptoms and life-threatening conditions. While COVID-19 infection can affect all ages, available evidence points to older age and pre-existing comorbidities, such as hypertension, diabetes, and coronary heart disease, as important risk factors related to increased mortality rates.[2-4] Moreover, recent reports from China and the U.S. have suggested that susceptibility, and perhaps even mortality, to COVID-19 infection might be influenced by the ABO blood …

Possible Role Of Tetracyclines On Covid-19: Recycling Well-Known Old Drugs From The Shelf, Martin Gnoni, Raul Vasquez-Gararatti, Angel Mena
The University of Louisville Journal of Respiratory Infections
We are in the midst of a pandemic due to the novel coronavirus SARS-CoV-2. Innovative therapies are in the lookup around the world. Recently, chloroquine and hydroxychloroquine in addition to azithromycin were proposed to be used in patients with severe disease even though strong evidence is lacking. We propose the use of tetracyclines in addition to anti-virals early in the curse of the disease in order to prevent the cytokine storm syndrome associated with COVID-19 and prevent ARDS. The proposed mechanisms of tetracyclines are: 1) anti-apoptotic properties; 2) decrease the Myeloperoxidase and ROS releaser from immune cells; 3) decrease neutrophil …

This study reported the efficacy of short-course corticosteroids and convalescent plasma (CP) transfusion in treating five patients with severe COVID-19 disease. Five adults (mean±standard deviation age: 70±9 years) with laboratory-confirmed COVID-19 and severe hypoxemia (PaO2/FiO2 [P/F]<100) requiring invasive mechanical ventilation received five days methylprednisolone (40 mg intravenously every 12 hours) and subsequent CP transfusion (250–400 ml). Compared with the baseline, P/F ratios increased by 46% and by 28% after short course corticosteroids and CP transfusion, respectively. Four patients survived. Short-course corticosteroids and CP transfusion may improve hypoxemia in patients with severe COVID-19 disease.

An important feature of COVID-19, the disease produced by the new coronavirus SARS-CoV-2, is the high number of health care workers (HCWs) that acquire the disease. In an initial report of 138 patients hospitalized with COVID-19 pneumonia in China, 40 patients (29%) were HCWs. One reason why HCWs are at higher risk of acquiring COVID-19 is that some patients with COVID-19 are admitted to the hospital without the classical presentation and are therefore not tested for the disease early during hospitalization. Presently in the US, it is recommended to test for COVID-19 when physicians suspect the disease. This subjective approach …
