Ameliorating effects of probiotics on alterations in iron homeostasis and inflammation in COVID-19

Abstract

IntroductionThe coronavirus disease (COVID-19) is caused by the severe acute syndrome coronavirus-2 (SARS-COV-2) and still threatens human life. This pandemic is still causing increased mortality throughout the world. Many recent studies have been conducted to discover the pathophysiology of this virus. Material and methods However, in this narrative review, we attempted to summarize some of the alterations in physiological pathways that were evident in this viral invasion. Excessive inflammation that progresses to cytokine storm, changes in humoral and cell-mediated immunity, and observed alterations in iron metabolism are included in the pathogenesis of the virus. Iron homeostasis disturbances may persist for more than two months after the onset of COVID-19, which may lead to reduced iron bioavailability, hypoferremia, hyperferritinemia, impaired hemoglobin, and red blood cell synthesis. Furthermore, hypoferriemia may impair immune system function. Until now, the traditional treatments discovered are still being tried. Results However, using probiotics as an adjuvant was shown to have beneficial effects on both iron homeostasis and immunity in COVID-19. Herein, we discussed the possible mechanisms achieved by probiotics to ameliorate iron and immunity changes based on the available literature. Conclusion We concluded that supplementing probiotics with conventional therapy may improve COVID-19 symptoms and outcomes. Taking into consideration the use of good quality probiotics and appropriate dosage, undesirable effects can be avoided.

Quality and Nutrient Loss in the Cooking Vegetable and Its Implications for Food and Nutrition Security in Ethiopia: A Review

“…42 Depending on the dose, some or all existing organisms, microbes, bacteria, and viruses are destroyed, delayed or unable to reproduce. 43 The culinary report states that, 25 vegetables must be cooked very carefully to obtain the required level of minerals and vitamins because careless cooking of vegetables destroys the plant's cell wall, releasing more nutrients bound to the cell wall. Cooked vegetables may contain more antioxidants than raw vegetables, including beta-carotene, lutein and lycopene.…”

COVID-19 in patients with anemia and haematological malignancies: risk factors, clinical guidelines, and emerging therapeutic approaches

“…Accordingly, COVID-19 likely induces a genetic change in new genes that cause SA [ 93 ]. In addition, SARS-CoV-2 interacts with Hb molecules through a cluster of differentiation 147 (CD147), CD2b, and other receptors commonly found on erythrocytes and other Hb cells, leading to Hb denaturation [ 94 ]. Considering that, hemoglobin concentration decreases and toxic heme is released, which usually causes hypoxia [ 94 ].…”

“…In addition, SARS-CoV-2 interacts with Hb molecules through a cluster of differentiation 147 (CD147), CD2b, and other receptors commonly found on erythrocytes and other Hb cells, leading to Hb denaturation [ 94 ]. Considering that, hemoglobin concentration decreases and toxic heme is released, which usually causes hypoxia [ 94 ]. Furthermore, a gradual decrease in the Hb concentration may promote SA and increase erythrocyte distribution width (RDW), indicating overproduction of immature erythrocytes and an increased risk of mortality [ 95 ] ( Fig.…”

Iron Chelation as a Potential Therapeutic Approach in Acute Lung Injury

“…The pathogenesis of COVID-19 includes inflammation, hypercoagulation, and immune dysfunction, and is associated with iron dysregulation [ 56 ]. First, SARS-CoV-2 might have a direct effect on hepcidin regulation [ 57 ]. SARS-CoV-2 spike protein has similarities to hepcidin, which potentially has an impact on ferroportin activity [ 58 ].…”
