简要总结
As of May 30th more than 23,000 cases of COVID -19 cases were confirmed in Egypt with total deaths of 913. Post viral entry, intense immune response against the virus with infiltration of monocytes and macrophages into alveolar cells with decreasing number of lymphocytes in peripheral blood along with reduced lymphocytes in lymphoid organs, hypercoagulability, thrombosis and multiple organ damage, The gut microbiota and immune homeostasis seem to have a back and forth relationship.
Also, gut microbiota derived signals are known to tune the immune cells for pro and anti-inflammatory responses thereby affecting the susceptibility to various diseases. Healthy gut microbiome essentially could be pivotal in maintaining an optimal immune system to prevent an array of excessive immune reactions that eventually become detrimental to lungs and vital organ systems.
Numerous studies have shown that the patient's nutritional status have a significant effect on an individual's immunity and over all health status and it has been suggested that nutritional deficiencies may predispose to severe forms of COVID-19 infections.
Co-existing non-communicable chronic diseases (NCDs) in COVID-19 patients have been found to delay patients recovery and worsen their prognosis, the reason may be due to aggravated inflammatory pathology found in NCDs exacerbating COVID-19 infection.
The aim of the study is to evaluate the role dietary habits among COVID-19 Egyptian patients and whether type of diet (Mediterranean or Western) will affect disease outcomes
详细描述
As of May 30th more than 23,000 cases of COVID -19 cases were confirmed in Egypt with total deaths of 913. There are over six million confirmed cases of COVID-19 and almost 370,000 deaths globally. COVID-19 originated from Wuhan city, China in early 2020, from their extending to the rest of the world. The virus belong to a large class of viruses known as β-coronaviruses with a large number of potential natural primary, intermediate and final hosts. Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is an enveloped RNA virus that typically spread by droplets causing pulmonary and extra-pulmonary complications.
COVID-19 can result in cytokine storm, which in severe cases can lead to acute respiratory distress syndrome (ARDS), sepsis and multiple organ dysfunction that can progress to death. Post SARS-CoV-2 entry, intense immune response against the virus with infiltration of monocytes and macrophages into alveolar cells with decreasing number of lymphocytes in peripheral blood along with reduced lymphocytes in lymphoid organs, hypercoagulability, thrombosis and multiple organ damage. This along with the fact that some patients of this disease have diarrhea points out towards a distinct possibility of involvement of gut-lung axis and may be the gut microbiota.
The gut microbiota and immune homeostasis seem to have a back and forth relationship. Also, gut microbiota derived signals are known to tune the immune cells for pro and anti-inflammatory responses thereby affecting the susceptibility to various diseases.
Many elderly and immune-compromised patients progress to serious adverse clinical outcomes, it is therefore tempting to speculate that in COVID-19, there is a possible cross-talk taking place between the lung and the gut microbiota which might influence the outcome of the clinical manifestation.
Healthy gut microbiome essentially could be pivotal in maintaining an optimal immune system to prevent an array of excessive immune reactions that eventually become detrimental to lungs and vital organ systems.
