Cytokine storm syndrome (CSS) is a critical condition induced by a cascade of cytokine activation, characterized by overwhelming systemic inflammation, hyperferritinaemia, haemodynamic instability and multiple organ failure. At the end of 2019, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China, and rapidly developed into a global pandemic. There is a dramatic increase of inflammatory cytokines in patients with COVID-19, suggesting the existence of cytokine storm in some critical illness patients. Here, we summarize the p

Severe acute respiratory syndrome-coronavirus 2, a novel betacoronavirus, has caused the global outbreak of a contagious infection named coronavirus disease-2019. Severely ill subjects have shown higher levels of pro-inflammatory cytokines. Cytokine storm is the term that can be used for a systemic inflammation leading to the production of inflammatory cytokines and activation of immune cells. In coronavirus disease-2019 infection, a cytokine storm contributes to the mortality rate of the disease and can lead to multiple-organ dysfunction syndrome through auto-destructive responses of systemic inflammation. Direct effects of the severe acute respiratory syndrome associated with infection as well as hyperinflammatory reactions are in association with disease complications. Besides acute respiratory distress syndrome, functional impairments of the cardiovascular system, central nervous system, kidneys, liver, and several others can be mentioned as the possible consequences. In addition to the current therapeutic approaches for coronavirus disease-2019, which are mostly supportive, stem cell-based therapies have shown the capacity for controlling the inflammation and attenuating the cytokine storm. Therefore, after a brief review of novel coronavirus characteristics, this review aims to explain the effects of coronavirus disease-2019 cytokine storm on different organs of the human body. The roles of stem cell-based therapies on attenuating cytokine release syndrome are also stated.

Global Pandemic

Until July 29th, the number of confirmed coronavirus (COVID-19) cases worldwide has risen to over 16 million, within which 655 k deaths. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) emerges as the 11th global pandemic disease, showing the highest infectivity and lowest infection fatality rate. In this review, we compare the immunopathology among SARS-CoV, Middle East respiratory syndrome coronavirus, and SARS-CoV2. SARS-CoV2 is similar to SARS-CoV; it can cause lymphocytopenia and a rising granulocyte count. Here we point out the human body and concentrated society make for an excellent incubator for virus evolution. Most research energies put into developing the SARS-CoV2 vaccine are trying to block virus infection. Sixty-five percent of severe patients die with multiple organ failure, inflammation, and cytokine storm, which indicates that the patient’s immune system maintains functionality. Finding a way to trigger the specific T cell subset and plasmablast in our body is the best shot to get away with SARS-CoV2.

COVID-19, occurring due to SARS-COV-2 infection, is the most recent pandemic disease that has led to three million deaths at the time of writing. A great deal of effort has been directed towards altering the virus trajectory and/or managing the interactions of the virus with its subsequent targets in the human body; these interactions can lead to a chain reaction-like state manifested by a cytokine storm and progress to multiple organ failure. During cytokine storms the ratio of pro-inflammatory to anti-inflammatory mediators is generally increased, which contributes to the instigation of hyper-inflammation and confers advantages to the virus. Because cytokine expression patterns fluctuate from one person to another and even within the same person from one time to another, we suggest a road map of COVID-19 management using an individual approach instead of focusing on the blockbuster process (one treatment for most people, if not all). Here, we highlight the biology of the virus, study the interaction between the virus and humans, and present potential pharmacological and non-pharmacological modulators that might contribute to the global war against SARS-COV-2. We suggest an algorithmic roadmap to manage COVID-19.

The global pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) has led to 47 m infected cases and 1. 2 m (2.6%) deaths. A hallmark of more severe cases of SARS-CoV-2 in patients with acute respiratory distress syndrome (ARDS) appears to be a virally-induced over-activation or unregulated response of the immune system, termed a “cytokine storm,” featuring elevated levels of pro-inflammatory cytokines such as IL-2, IL-6, IL-7, IL-22, CXCL10, and TNFα. Whilst the lungs are the primary site of infection for SARS-CoV-2, in more severe cases its effects can be detected in multiple organ systems. Indeed, many COVID-19 positive patients develop cardiovascular complications, such as myocardial injury, myocarditis, cardiac arrhythmia, and thromboembolism, which are associated with higher mortality. Drug and cell therapies targeting immunosuppression have been suggested to help combat the cytokine storm. In particular, mesenchymal stromal cells (MSCs), owing to their powerful immunomodulatory ability, have shown promise in early clinical studies to avoid, prevent or attenuate the cytokine storm. In this review, we will discuss the mechanistic underpinnings of the cytokine storm on the cardiovascular system, and how MSCs potentially attenuate the damage caused by the cytokine storm induced by COVID-19. We will also address how MSC transplantation could alleviate the long-term complications seen in some COVID-19 patients, such as improving tissue repair and regeneration.

Vast Range

The global pandemic of coronavirus (CoV) d0isease 2019 (COVID-19), caused by severe acute respiratory syndrome CoV (SARS-CoV 2), has been a challenging event for every individual. It is known that COVID-19 may exhibit a vast range of symptoms ranging from mild to severe. Acute respiratory distress syndrome (ARDS) and multiple organ failure are the most common causes of death in COVID-19 cases [3]. Accumulating evidence shows that T-helper type (Th-1) inflammation cascade plays a major role in COVID-19 pathogenesis. It is proposed that aberrant immune reaction, or known as cytokine storm, is one of the main causals of ARDS in COVID-19 case, while dupilumab, the first Food and Drug Administration-approved immunomodulatory treatment for atopic dermatitis, is known for its effectiveness in suppressing the Th-2 inflammation pathway. It is postulated that both types of inflammation can cross-regulate each other. Therefore, some may believe that the regression of Th-2 cascade may upregulate the Th-1 cascade, leading to an exaggerated cytokine storm. This hypothesis leads to the uncertainty of the safety of continuing this modality during the pandemic.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus responsible for the current global pandemic, coronavirus disease 2019 (COVID-19). COVID-19 usually presents with respiratory symptoms but can affect multiple organ systems. A wide spectrum of complications can occur depending upon the comorbidities of patients. There is limited literature available regarding the presentation and outcome of COVID-19 in chronic lymphocytic leukaemia (CLL) patients. We report 2 cases of COVID-19-induced hyperleucocytosis (WBC count >100,000/?l) in CLL patients.

After initially emerging in late 2019, coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread rapidly to cause a global pandemic. SARS-CoV-2 is a betacoronavirus that is closely related to severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, all of which can cause severe lung injury, respiratory distress and cytokine storm. While mortality rates associated with SARS-CoV-2 are lower than those associated with severe acute respiratory syndrome coronavirus or Middle East respiratory syndrome coronavirus, it is more contagious and spreads more rapidly than these other viruses. This article summarises the epidemiology and potential options for treating COVID-19 to give a foundation for future studies of the diagnosis, treatment and prevention of this deadly disease.
