COVID-19 patients may present with myocarditis: A case report emphasizing the cardiac involvement of SARS-CoV-2

Effect of polyphenols against complications of COVID-19: current evidence and potential efficacy

The COVID-19 pandemic that started in 2019 and resulted in significant morbidity and mortality continues to be a significant global health challenge, characterized by inflammation, oxidative stress, and immune system dysfunction.. Developing therapies for preventing or treating COVID-19 remains an important goal for pharmacology and drug development research. Polyphenols are effective against various viral infections and can be extracted and isolated from plants without losing their therapeutic potential. Researchers have developed methods for separating and isolating polyphenols from complex matrices. Polyphenols are effective in treating common viral infections, including COVID-19, and can also boost immunity. Polyphenolic-based antiviral medications can mitigate SARS-CoV-2 enzymes vital to virus replication and infection. Individual polyphenolic triterpenoids, flavonoids, anthraquinonoids, and tannins may also inhibit the SARS-CoV-2 protease. Polyphenol pharmacophore structures identified to date can explain their action and lead to the design of novel anti-COVID-19 compounds. Polyphenol-containing mixtures offer the advantages of a well-recognized safety profile with few known severe side effects. However, studies to date are limited, and further animal studies and randomized controlled trials are needed in future studies. The purpose of this study was to review and present the latest findings on the therapeutic impact of plant-derived polyphenols on COVID-19 infection and its complications. Exploring alternative approaches to traditional therapies could aid in developing novel drugs and remedies against coronavirus infection.

Evaluation of tuberculosis infection in COVID-19 patients: a case of tuberculosis and COVID-19 co-infection

The COVID-19 pandemic affected millions of people worldwide, becoming a challenge of every nation. Since the COVID-19 can present wide spectrum of clinical signs and symptoms, patients with symptoms similar to that of COVID-19 may be misdiagnosed during the context of COVID-19 pandemic. In this regard, various co-infections may affect the outcome of COVID-19 patients if it lefts undiagnosed, especially during the administration of immunosuppressive drugs. Similar to COVID-19, TB affect the lungs and respiratory airways primarily. These two diseases have resembling symptoms, including dry cough, fever, and dyspnea. Due to the importance of early COVID-19 diagnosis, many other respiratory infectious diseases such as tuberculosis (TB) may be missed. Herein, a case of COVID-19 and tuberculosis co-infection is presented.
