Treatment

A review of the literature on existing drugs that could help to treat COVID-19 

The authors of this literature review identified 22 articles that reported on the effectiveness of existing drugs against COVID-19. Published between January 1 and March 25, the articles include case reports, lab tests, and animal trials. They cover four categories of drug: antiviral/anti-inflammatory, antimalarial, traditional Chinese, and others.  

Outcomes of severe COVID-19 patients who received remdesivir on a compassionate-use basis  

This paper describes a program sponsored by Gilead Sciences. Patients with severe COVID-19 received remdesivir, a nucleotide analogue prodrug that inhibits viral RNA polymerases, on a compassionate-use basis. While clinical improvement occurred in over half the patients, randomized controlled trials will soon provide more informative evidence about the drug. 

Evaluating the evidence for using remdesivir to treat patients with COVID-19  

The authors of this paper note that treating patients with “conventional drugs in new use” has become a feasible option for COVID-19, and that remdesivir could become a “specific drug” for the disease. After examining aspects of both the virus and the disease, the paper analyzes remdesivir to establish the feasibility of conducting experiments on COVID-19. 

A network-based methodology for repurposing drugs to target novel coronavirus 2019-nCoV/SARS-CoV-2 

As a drug discovery strategy, drug repurposing has the potential to achieve its goal quicker and at a lower cost than de novo drug discovery. With that in mind, these researchers have developed a powerful, network-based methodology capable of rapidly identifying possible repurposable drugs and potential drug combinations for targeting SARS-CoV-2. 

Unravelling the cellular factors used by SARS-CoV-2 for cell entry

This study shows that SARS-CoV-2 infection relies on host cell factors ACE2 and TMPRSS2, and that a clinically proven protease inhibitor can block it. The authors also describe how SARS-CoV antibodies could offer some protection against SARS-CoV-2. The results provide important knowledge about the new virus, and point to a target for antiviral intervention.

Narrative review of proposed pharmacologic treatments for COVID-19

This paper reviews relevant English-language articles (randomized controlled trials, case reports, case series, reviews) and active clinical trials focusing on major proposed treatments for COVID-19. It addresses selected repurposed drugs, selected investigational drugs, adjunctive therapies, and current clinical treatment experience and recommendations.

Passive immunization via monoclonal antibodies as a possible therapeutic intervention for COVID-19

This article discusses neutralizing monoclonal antibodies and their potential for treating coronaviruses. The authors outline existing knowledge about antibodies that performed well in targeting the spike proteins of SARS-CoV and MERS-CoV. Since these viruses are similar to SARS-CoV-2, the findings could potentially be effective for the current pandemic.

Using a tried-and-tested approach for the new challenge of COVID-19

Noting that passive immunization has been successfully used to treat infectious diseases, this editorial refers to studies in which convalescent plasma was found to reduce mortality and viral load in SARS-CoV and MERS-CoV. Serum from recovered COVID-19 patients could potentially prove helpful in the short term, until definitive treatments are found.

Initial clinical experience of administering convalescent plasma to critically ill COVID-19 patients in Shenzhen, China

In this uncontrolled case series, five patients who were critically ill with COVID-19 and ARDS received convalescent plasma containing neutralizing antibodies. The patients’ clinical status subsequently improved, suggesting that plasma transfusion could be beneficial. However, the study had a number of limitations and randomized clinical trials are needed.

Ivermectin, an FDA-approved drug, found to inhibit SARS-CoV-2 replication in vitro

Ivermectin is an FDA-approved antiparasitic that has shown broad antiviral activity. This study specifically tested the drug against SARS-CoV-2 in vitro. The results show that, in the tested system, a single dose can control viral replication within 24 to 48 hours. Ivermectin should therefore be further considered as a possible antiviral for SARS-CoV-2.

Ultrasound

First report on point-of-care lung ultrasound in COVID-19 pneumonia, and potential applications

Researchers from Italy provide the first lung ultrasound description of COVID-19 pneumonia in a 52-year-old man. As well as documenting the findings, which were obtained at the bedside, the authors also explain how the examination was performed. They conclude by outlining the benefits and possible applications of lung ultrasound in the current pandemic.

Early experience with lung ultrasonography for evaluating SARS-CoV-19 infection in China

The authors of this letter report on using lung ultrasonography in 20 patients with COVID-19. They list the characteristic findings and compare them with CT findings. After noting a key limitation of the modality, the authors conclude that the benefits – such as repeatability and point-of-care use – mean that it has major utility for managing COVID-19.

Can lung ultrasound help in the early diagnosis of COVID-19 pneumonia in critical care settings?

Given that CT scanning is often unavailable in emergency departments, investigators in Italy evaluated the use of lung ultrasound in 12 patients who presented to an emergency department with COVID-19 pneumonia. The patients underwent bedside ultrasound and CT examinations, and there was a strong correlation between the findings from each modality.

A simple, quantitative, and reproducible method for standardized use of lung ultrasound for COVID-19 patients

Growing evidence shows that lung ultrasound can be useful in patients with COVID-19. Given that the virus has caused a global emergency, a globally unified approach is needed. With this in mind, a team of experts from Italy has developed a standardized approach to lung ultrasound that can be used to manage COVID-19 patients around the world.

Guidelines for cleaning and preparing ultrasound transducers and equipment, and for safe handling and use of coupling gel
