Hypoxic Training

COVID-19, a disease caused by the novel coronavirus SARS-CoV-2, primarily affects lung tissue and disrupts gas exchange, leading to acute respiratory distress syndrome, systemic hypoxia, and lung damage. The search for methods of prevention and rehabilitation, especially after suffering from pneumonia caused by COVID-19, is on the agenda. This article discusses the possibilities of the interval hypoxic training (IHT) method for preventing infections by initiating nitric oxide production in the body. One of the main effects of IHT is the balanced stimulation of nitric oxide (NO) secretion. Over the past two decades, there has been an increasing interest in the function of nitric oxide (NO) in the human body. Nitric oxide plays a key role in maintaining normal vascular function and regulating inflammatory processes, including those leading to lung damage and the development of acute respiratory distress syndrome (ARDS). Our immune system destroys bacteria and viruses by oxidative burst, i.e. when oxygen accumulates inside the cell. This process also involves nitric oxide, a signaling molecule that has an antibacterial and antiviral effect, as well as regulates vascular tone and affects the permeability of the cell wall. Interval hypoxytherapy enhances endogenous oxidative protection and increases the amount of nitric oxide, thus allowing the body’s cells to resist infection more effectively. Mitochondrial NOS induction and mitochondrial NO synthesis increase under the action of pathogenic factors on the cell. By modulating the activity of mtNOS and the synthesis of mitochondrial NO, it is possible to increase the resistance to hypoxic effects. Interval hypo-hyperoxic training as an effective non-specific method of increasing the body’s defenses is indispensable not only in the prevention of viral infection, but also in rehabilitation after viral pneumonia, as well as as a method that reduces the severity of viral infection in the event of infection.

Abstract Background Inhalation injury from smoke or chemical products and carbon monoxide poisoning are major causes of death in burn patients from fire accidents. Respiratory tract injuries from inhalation injury and carbon monoxide poisoning can lead to acute respiratory distress syndrome and cytokine storm syndrome. In the case of acute respiratory failure needing mechanical ventilation accompanied by cytokine storm, mortality is high and immediate adequate treatment at the emergency department is very important. Case presentation This report describes a case of acute respiratory distress syndrome and cytokine storm followed by carbon monoxide poisoning in a 34-year-old Korean male patient who was in a house fire, and was successfully treated by extracorporeal membrane oxygenation and direct hemoperfusion with polymyxin B-immobilized fiber column at emergency department. Conclusions To prevent mortality in acute respiratory distress syndrome with cytokine storm from inhalation injury and to promote a better prognosis, we suggest that early implication of extracorporeal membranous oxygenation along with direct hemoperfusion with polymyxin B-immobilized fiber column even at the emergency department should be considered.

Abstract After wreaking havoc on a global level with a total of 5,488,825 confirmed cases and 349,095 deaths as of May 2020, severe acute respiratory syndrome coronavirus 2 is truly living up to the expectations of a 21st-century pandemic. Since the major cause of mortality is a respiratory failure from acute respiratory distress syndrome, the only present-day management option is supportive as the transmission relies solely on human-to-human contact. Patients suffering from coronavirus disease 2019 (COVID-19) should be tested for hyper inflammation to screen those for whom immunosuppression can increases chances of survival. As more and more clinical data surfaces, it suggests patients with mild or severe cytokine storms are at greater risk of failing fatally and hence these cytokine storms should be targets for treatment in salvaging COVID-19 patients.

Background: Severe pneumonia and acute respiratory distress syndrome (ARDS) due to COVID-19 is a challenge for nowadays medical practice. Although there is no clarity in the principal mechanism of lung damage and ARDS development, it has been suggested that one of the main reasons of this pathology is the hyperactivation of the immune system, better known as cytokine storm syndrome. Tocilizumab has been proposed to treat COVID-19 severe cases associated to ARDS. Results & methodology: Here we present two successful cases of tocilizumab administration in two COVID-19 patients with prior administration of antiviral therapy (hydroxychloroquine, azithromycin, lopinavir and ritonavir) with adequate response and resolution of ARDS, septic shock and severe pneumonia within the first 72 h. Discussion & conclusion: This case supports the usage of tocilizumab as an effective therapy in COVID-19 associated cytokine storm syndrome. Further studies should be done in order to assess its effectiveness and security.

In early December 2019, the pandemic of coronavirus disease 2019 (COVID-19) began in Wuhan City, Hubei Province, China. Since then, it has propagated rapidly and turned into a major global crisis due to the high virus spreading. Acute respiratory distress syndrome (ARDS) is considered as a defining cause of the death cases. Cytokine storm and oxidative stress are the main players of ARDS development during respiratory virus infections. In this review, we discussed molecular mechanisms of a fatal vicious circle between oxidative stress and cytokine storm during COVID-19 infection. We also described how aging can inflame the vicious circle. Keywords: acute respiratory distress syndrome (ARDS), COVID-19, cytokine storm, oxidative stress

Immunomodulating Drugs

Sars-CoV-2 complications include pneumonia and acute respiratory distress syndrome (ARDS), which requires intensive care unit admission. These conditions have rapidly overwhelmed healthcare systems, with detrimental effects on the quality of care and increased mortality. Social isolation strategies have been implemented worldwide with the aim of reducing hospital pressure. Among therapeutic strategies, the use of immunomodulating drugs, to improve prognosis, seems promising. Particularly, since pneumonia and ARDS are associated with a cytokine storm, drugs belonging to therapeutic classes as anti-IL-6, anti-TNF and JAK inhibitors, are currently studied. In this paper, we discuss the potential advantages of the most promising pharmacological approaches.
