ABSTRACT
From March 2020, the coronavirus disease 2019 (COVID-19) pandemic challenged public health and healthcare systems worldwide. Viral infection is one of the environmental factors that has been associated with the development, relapse, or exacerbation of systemic lupus erythematosus (SLE). SLE patients are at an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) because of immune system dysfunction related to their disease as well as immunosuppression medications. So far, the most effective way to reduce SARS-CoV-2 infection-induced hospitalization and death is vaccination. On the other hand, SLE patients present distinct challenges related to the safety and effectiveness of SARS-CoV-2 vaccination. We have reviewed some reports on the onset or flare of SLE post-COVID-19 vaccination. Of note, the mRNA COVID-19 vaccines are associated with increased SLE disease activity, more frequently than the other types of COVID-19 vaccines. © 2023 The Author(s).
ABSTRACT
We believe that vaccination is just a way to eliminate or strongly stop the COVID-19. In this regard, there are several vaccines with different efficacy and side effects. It is urgently required to have some efficient vaccines for the prevention and control of SARS-CoV-2. In this review, international databases were considered for searching relevant articles from 1 January 2020 to 1 May 2021. Keywords were COVID-19, novel coronavirus, 2019-nCoV, coronavirus disease 2019, vaccine, Sputnik V, Gamaleya, Gam-COVID-Vac, Sinopharm, BBIBP-CorV, AstraZeneca, Vaxzevria, Oxford, ChAdOx1 nCoV-19 and AZD1222. Three Sputnik V, Sinopharm and AstraZeneca vaccines are useful to gain herd immunity. Enough intervals (at least three weeks/21 days) must be considered for sufficient neutralizing antibody titers. What is important is that the vaccination should be accelerated with each of the aforementioned three vaccines to achieve herd immunity in a shorter period of time because all three vaccines provide 100% prevention of severe COVID-19.
ABSTRACT
A novel coronavirus (severe acute respiratory syndrome coronavirus [SARS-CoV-2]), has been causing a COVID-19 pandemic of acute respiratory syndrome in humans since December 2019. It appears to be similar in structure to the virus that caused the SARS-CoV outbreak of 18 years ago. However, in addition to the respiratory disorders, the COVID-19 patients might suffer extra-pulmonary disorders, including gut dysfunction or liver dysfunction complications, which show as gut-lung crosstalk. Fecal specimens should be considered as a source of detection of SARS-CoV-2 as one of the routine diagnostic tests in order to guide hospital's liberation and release of quarantine of patients.
ABSTRACT
Coronavirus disease 2019 (COVID-19), the currently prevailing pandemic that has besieged the whole world, is caused by a novel coronavirus, named as, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Initially, there was a focus on respiratory disease, which was and is the most predominant presentation. However, with increasing spread of the infection and consequent increasing knowledge and experience about the disease, it has become apparent that the virus has wide-ranging effects on other organs and systems, including heart, blood, kidney and gastrointestinal tract. A variety of mechanisms are involved in viral damage of these organs. Blood vessels, particularly the microvasculature, and blood clotting systems are also frequently targeted by the virus, especially in severe cases. This review narrates the available evidence on the mechanisms underlying hypercoagulability and thrombotic tendency in COVID-19 disease. © 2021 The Author(s);Published by Society of Diabetic Nephropathy Prevention.
