The novel coronavirus infection, COVID-19, is a highly contagious viral disease associated with acute, severe respiratory syndrome, which is based on the development of pronounced thrombo-inflammatory syndrome. As the number of patients with COVID-19 increased, heart damage has been reported, especially in patients with severe and critical COVID-19. This review describes the role of angiotensin-converting enzyme 2 receptor in the regulation of viral entry, the variety of damages to the heart and coronary arteries, and the importance of arterial hypertension and of the use of renin-angiotensin-aldosterone system inhibitors in the prognosis of patients with COVID-19.

Abstract Background: The outbreak of coronavirus disease (COVID-19) was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), through its surface spike glycoprotein (S-protein) recognition on the receptor Angiotensin-converting enzyme 2 (ACE2) in humans. However, it remains unclear how genetic variations in ACE2 may affect its function and structure, and consequently alter the recognition by SARS-CoV-2. Methods: We have systemically characterized missense variants in the gene ACE2 using data from the Genome Aggregation Database (gnomAD; N = 141,456). To investigate the putative deleterious role of missense variants, six existing functional prediction tools were applied to evaluate their impact. We further analyzed the structural flexibility of ACE2 and its protein-protein interface with the S-protein of SARS-CoV-2 using our developed Legion Interfaces Analysis (LiAn) program.Results: Here, we characterized a total of 12 ACE2 putative deleterious missense variants. Of those 12 variants, we further showed that p.His378Arg could directly weaken the binding of catalytic metal atom to decrease ACE2 activity and p.Ser19Pro could distort the most important helix to the S-protein. Another seven missense variants may affect secondary structures (i.e. p.Gly211Arg; p.Asp206Gly; p.Arg219Cys; p.Arg219His, p.Lys341Arg, p.Ile468Val, and p.Ser547Cys), whereas p.Ile468Val with AF = 0.01 is only present in Asian.Conclusions: We provide strong evidence of putative deleterious missense variants in ACE2 that are present in specific populations, which could disrupt the function and structure of ACE2. These findings provide novel insight into the genetic variation in ACE2 which may affect the SARS-CoV-2 recognition and infection, and COVID-19 susceptibility and treatment.

Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), is an ongoing global public health challenge. Current clinical data suggest that, in COVID-19 patients, arterial hypertension (AH) is one of the most common cardiovascular comorbidities; it can worsen outcomes and increase the risk of admission to intensive care unit (ICU). The exact mechanisms through which AH contributes to the poor prognosis in COVID-19 are not yet clear. The putative relationship between AH and COVID-19 may be linked to the role of angiotensin-converting enzyme 2 (ACE2), a key element of the AH pathophysiology. Another mechanism connecting AH and COVID-19 is the dysregulation of the immune system resulting in a cytokine storm, mediated by an imbalanced response of T helper cells subtypes. Therefore, it is essential to optimize blood pressure control in hypertensive patients and monitor them carefully for cardiovascular and other complications for the duration of COVID-19 infection. The question whether AH-linked ACE2 gene polymorphisms increase the risk and/or worsen the course of SARS-CoV-2 infection should also receive further consideration.

The aim of the study was to identify the role of cytokine storm in COVID-19, that emerged at the end of 2019, based on the analysis of 80 publications, including 17.4% Russian and 82.6% foreign publications for 2014–2020 with an average impact factor of 11.94 and a maximum of 74.699. This review includes an in-depth discussion of the possible causes and pathogenetic factors of cytokine storm syndrome development caused by COVID-19. The results of research on the use of various principles of cytokine storm correction are provided. It has been established that lung damage and the development of a fatal outcome are caused not by the virus itself, but by the hyperreaction of the body's immune system. The leading role in this process belongs to the cytokine storm, including the action of IL-6.

This review aimed to focus on using foods to boost immunity against COVID-19 in all age groups. In human, coronavirus causes the common cold, severe acute respiratory syndrome (SARS), and a major threat to public health. The novel coronavirus was declared a pandemic by the World Health Organization due to its rapid infectivity. COVID-19 infection is most probably reported in people with low immunity response. The nutrients, which show beneficial effects on the immune system, are called immune nutrients and diet is called immune diet. A healthy diet can reduce the risk of infection of COVID-19 and can prevent disease. Nutritional food intake is also necessary for people with chronic illness, obese persons, diabetes, cardiovascular disease, cognitive dysfunction like anxiety and depression. All nutrients are essential for maintaining immunity and providing appropriate amounts of protein, fat, carbohydrate, vitamins, and minerals for the surveillance mode of keeping us from getting sick. The use of plenty of water, minerals such as micronutrients, zinc, copper, selenium, iron, magnesium, food rich in vitamins, and a good lifestyle can promote health and overwhelm this coronavirus infection.

Обзор посвящен анализу дерматологических проявлений при новой коронавирусной инфекции COVID-19, информация о которых непрерывно обновляется и дополняется. Однако до сих пор имеющиеся данные не были систематизированы. Цель обзора: проанализировать дерматологические проявления новой коронавирусной инфекции COVID-19. В среднем, у 12,5–20,4% пациентов с подтвержденным COVID-19 развились кожные проявления. Вопрос о том, являются ли кожные симптомы вторичным следствием респираторной инфекции или первичной инфекцией самой кожи, на данный момент остается открытым. Обсуждаются вероятные механизмы развития поражений кожи и роли системы комплемента и гиперкоагуляции крови в патогенезе развития дерматологических проявлений. В обзоре также приводятся клинические примеры вовлечения кожных покровов в инфекционный процесс при COVID-19. Поскольку COVID-19 имеет тенденцию к бессимптомному течению в течение 14 дней после заражения, кожные проявления могут служить индикатором инфекции, способствуя своевременной диагностике. Кроме того, осведомленность врачей о кожных симптомах, связанных с инфекцией COVID-19, имеет решающее значение для предотвращения неправильного диагноза заболевания. Review focuses on the analysis of dermatological manifestations of the novel coronovirus infection COVID-19; this information is continuously updated and supplemented. However, the available data have not been systematized until now. The purpose of this review is to analyze the dermatological manifestations of the novel coronavirus infection COVID-19. On average, 12.5–20.4% of patients with confirmed COVID-19 have developed skin manifestations. Whether the skin symptoms are a secondary consequence of a respiratory infection or a primary infection of the skin itself presently remains still open. Possible mechanisms of skin lesions development are discussed as well as the role of the complement system and blood hypercoagulation in the pathogenesis of the dermatological manifestations. The review also provides clinical examples of skin involvement in the infectious process in COVID-19. Since COVID-19 tends to be asymptomatic within 14 days of infection, so skin manifestations can serve as an indicator of infection, facilitating timely diagnosis. Moreover, physicians’ awareness of skin symptoms associated with COVID-19 is crucial for preventing misdiagnosis of the disease.

The novel coronavirus (SARS-CoV-2) has produced millions of infections and deaths worldwide. It is believed that adaptive immunity to the virus occurs although with variation in its pattern and duration. While uncommon, confirmed reinfection with the novel coronavirus has been reported. Telemedicine has emerged as a viable tool for the delivery of healthcare in lieu of in-person patient contact. The variable and occasionally rapid course of clinical disease raises safety concerns of using telemedicine in the clinical management of acute infection with the novel coronavirus. We present a case of novel coronavirus infection in an immunocompetent individual with obstructive sleep apnea (OSA) who failed to manifest an adaptive immune response to acute infection and was subsequently reinfected. The case highlights the use of telemedicine in managing novel coronavirus respiratory disease and the potential role of OSA as a disease facilitator.

Asthenia is a non-specific syndrome common in general practice and occurs in patients with acute and chronic somatic disorders, including infectious ones. The novel coronavirus infection (COVID-19) is one of the leading causes of severe and persistent asthenia. The hypothalamicpituitary- adrenal axis is essential for the development of asthenia since its dysfunction provoked by various factors (including infections) results in electrolyte metabolism impairment with hypokalemia and hypomagnesemia. This paper describes a hypothetical pathogenic mechanism of asthenia after the COVID-19, which implies over-activation of the renin-angiotensin-aldosterone system that, in particular, leads to hypokalemia. The role of pharmacotherapy prescribed for the COVID-19 is highlighted. Study results demonstrate a high rate of hypokalemia in patients with the COVID-19 and suggest a direct correlation between the severity of hypokalemia and the activity of viral infection. Furthermore, the detection of electrolyte abnormalities is essential in both acute infection and convalescence. Finally, the authors consider ways of relieving this pathological condition.

An acute respiratory disease is rampantly spreading in population worldwide caused by a novel coronavirus (SARS-CoV-2, also known as COVID-19). The COVID-19 is a major source of disaster in the 21thcentury. It has spread throughout China and is received as a pandemic worldwide. To date (18th May 2020), a total of 4,827,272patients are infected and more than 3,17,174confirmed deaths have been reported with 6.57% fatality rate. Several research investigations have identified that COVID-19 belongs to ?-coronavirus family and has a highly identical genomic structure to bat coronavirus. The novel coronavirus uses the same receptor, ACE-2 (angiotensin-converting enzyme 2) as that for SARS-CoV, and mainly spreads through the respiratory tract. As per WHO, symptoms include shortness of breath especially in the lower respiratory tract, sore, throat, cough, headaches, and fever. However, the specific drugs required to prevent/treat an attack is a major need at this current point of time. In this regard, we conducted a systematic review on coronavirus to cover the molecular mechanism of viral entry and replication, which provides the basis of future management of COVID-19.

COVID-19 has emerged as a dreadful pandemic caused by the virus SARS-CoV-2. Though the number of patients recovering from infection is encouraging, sturdy cure is still being researched upon and the effective vaccines are yet to be rigidly resolute. COVID-19 has so far instigated a massive loss of lives globally and even the countries with the most advanced healthcare systems have come under its grasp. Health experts suggest in such case “Prevention is better than cure” which includes an appropriate daily lifestyle and a rugged immune system that could help mankind surmount this peril. This review highlights the importance of influential herbs and their medicinal significance. Biomedical articles were explored from PubMed, Google Scholar, Web of Science for the period of 2010-2021. Guidelines from the Ministry of Ayush (India) were also considered. The Ayurveda does not mention any cure for the novel coronavirus; however, it emphasizes the means of boosting one’s immunity. Accordingly, this article highlights some of the role of prevalent Ayurvedic herbs in promoting immunity for combating the novel coronavirus. The herbs in combination with drugs could be utilized for the sake of curtailing the side effects as well as the malefic repercussions of strong synthetic drugs used for treating COVID-19 patients, which would be a paramount leap in the field of Ayurveda as well as western-style medicine. However, the beneficial effects of these traditional medicines and their clinical trials remained to be known. We reviewed the latest updates on traditional medicines proposed for promoting immunity towards COVID-19.
