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.

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 …

Louisville Coronavirus Surveillance Program, Julio A. Ramirez, Kenneth E. Palmer, Ruth Carrico, Forest W. Arnold, Donghoon Chung, Leslie A Wolf

The University of Louisville Journal of Respiratory Infections

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 …

Community-acquired pneumonia (CAP) may be caused by serotypes of endemic HCoVs or highly pathogenic HCoVs. In this review, we compared clinical characteristics, management, outcomes, and infection control practices for patients with CAP due to endemic HCoVs versus patients with CAP due to 2019 novel coronavirus (SARS-CoV-2).


Developments For The Treatment Of Invasive Infections Due To Multidrug-Resistant Acinetobacter Baumannii, David Laurent, Richard Drew, Dustin Wilson Nov 2019

Developments For The Treatment Of Invasive Infections Due To Multidrug-Resistant Acinetobacter Baumannii, David Laurent, Richard Drew, Dustin Wilson

The University of Louisville Journal of Respiratory Infections

Acinetobacter baumannii is a significant pathogen in healthcare settings (specifically prominent in healthcare- and ventilator-associated pneumonia) due primarily to its virulence and resistance to a wide variety of antimicrobial drug classes, including carbapenems (CRAB). Existing therapies (notably polymyxins, minocycline, tigecycline, amikacin, and sulbactam) often result in suboptimal tissue concentrations, high rates of toxicity, and increasing rates of resistance. Although utilizing combinations of antibiotics (specifically those containing colistin) have been employed, results have been mixed, and control trials are lacking. Eravacycline is a novel tetracycline with an improved pharmacokinetic profile and more potent activity against A. baumannii relative to tigecycline. Cefiderocol …

The University of Louisville Journal of Respiratory Infections

Finding relevant biomarkers as a potential predictor of severity for patients hospitalized with community acquired pneumonia (CAP), in addition to the clinical scoring system, could advance progress towards more effective patient management. The inflammatory marker, C-reactive protein (CRP), which is elevated in the pathogenesis of many infectious diseases, may be a key biomarker target for CAP. Previous studies have shown that serum CRP may be a useful diagnostic marker for pneumonia in hospitalized patients with acute respiratory symptoms. The main aims of this study were to determine the correlation between serum and urine CRP levels in hospitalized patients with CAP, …

Assessment Of Pneumonia Severity Indices As Mortality Predictors, Connor L. English, Thomas Chandler, Brian E. Guinn, Stephen P. Furmanek, Julio A. Ramirez

The University of Louisville Journal of Respiratory Infections

BACKGROUND

The leading cause of infectious disease death in the United States is community-acquired pneumonia (CAP). Several pneumonia severity indices exist and are widely used as tools to assist physicians regarding site of care based on risk of death. However, limited data exists that discerns which of the most commonly used severity scores is the best predictor of mortality across multiple time points. The objective of this study is to determine the best mortality predictor at different time points between four of the most commonly used pneumonia severity scores.

METHODS

This was a secondary analysis of a prospective, multicenter, population-based, …

Development Of A Real-Time Pcr Assay For Pneumocystis Jirovecii On The Luminex Aries® Platform, Subathra Marimuthu, Kuldeep Ghosh, Leslie A Wolf

The University of Louisville Journal of Respiratory Infections

Pneumocystis pneumonia (PCP) is an opportunistic infection caused by the fungus Pneumocystis jirovecii. Infection with P. jirovecii can result in serious illness in patients with a weakened immune system, and can lead to death if it is not properly diagnosed and treated. Direct detection of P. jirovecii in lower respiratory tract specimens such as bronchoalveolar lavage (BAL) is preferred for rapid diagnosis, a laboratory service currently not available locally. We report here the development of a diagnostic real-time Polymerase Chain Reaction (PCR) assay using BAL specimens to detect P. jirovecii. By targeting the multi-copy mitochondrial large subunit ribosomal …
