The “Coronavirus disease 19 (COVID-19)” is caused by “Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)”, a newly discovered member of the Coronaviridae family of viruses which is a highly communicable. There is no effective medical treatment till date for Coronavirus disease hence prevention is the best way to keep disease away. Rasayana proved to be highly efficacious and cost effective for the Prevention and Control of viral infections when vaccines and standard therapies are lacking. Rasayana Chikitsa is one of the eight branches of Ashtanga Ayurveda which helps to maintain healthy life style. Rasayana improves immunity and performs many vital functions of human body. Vyadhikshamatva that is immune mechanism of the body is involved in Prevention of the occurrence of a new disease and it also decreases the virulence and progression of an existing disease. In COVID-19 the Respiratory system mainly get affected which is evident from its symptoms like cold, cough and breathlessness. Here the drugs help in enhancing immune system and strengthening functions of Respiratory system can be useful. For this purpose, the Rasayana like Chyavanprasha, Agastya Haritaki, Pippali Rasayana, Guduchi, Yashtimadhu, Haridra, Ashwagandha, Tulsi are used. Rasayana working on Respiratory system are best for Prevention of Coronavirus and boosting immune system. Rasayana Chikitsa can be effective in the Prevention as well as reducing symptoms of COVID-19.

AbstractVarious nutrients can change cell structure, cellular metabolism, and cell function which is particularly important for cells of the immune system as nutrient availability is associated with the activation and function of diverse immune subsets. The most important nutrients for immune cell function and fate appear to be glucose, amino acids, fatty acids, and vitamin D. This perspective will describe recently published information describing the mechanism of action of prominent nutritional intervention agents where evidence exists as to their action and potency.

Background: It is known that Vitamin D can increase the body’s immunity against some viral infections. Many people around the world have vitamin D deficiency and, therefore, this has become a public concern whether vitamin D is an important factor protecting against COVID-19 infection. In this paper, the data about the roles of vitamin D on immunity and recovery from viral infections, especially novel Coronavirus disease (COVID-19) is reviewed. Methods: The electronic databases of Pubmed, Google Scholar, Research Gate, Excerpta Media Database (EMBASE) and Medical and Health Education (Medrix) were searched. Results: Vitamin D is considered an important factor in immune homeostasis. Various effects have been considered for this nutrient on the immune system, particularly because of vitamin D receptor (VDR) and Cytochrome P450 Family 27 Subfamily B Member 1 (CYP27B1) expression in most of the immune cells. Vitamin D can raise cellular immunity, reduce cytokine storm and enhance antioxidants production. It also has modulatory effects on Angiotensin-converting enzyme 2 (ACE2) receptors and might have protective functions against acute lung injuries, including COVID-19 infection. However, there are some articles against this positive effect. Conclusion: Vitamin D supplementation is reported to be effective in the enhancement of the immune system and might be effective in the treatment and prevention of COVID-19 infection, especially in those with its deficiency. However, it should be considered that vitamin D deficiency shows the overall health status of the patients and cannot be considered specific for COVID-19 infection.

Background: In Covid-19 infection, leukopenia, inflammation, and elevated liver enzymes are found in most patients. Also, vitamin D deficiency attenuate the immune system and predispose a person more susceptible to infection. In this context, we aimed to evaluate vitamin D, Electrolytes, Complete blood count, Liver enzymes, Urea, Creatinine, Albumin, CRP and ESR levels in patients with Covid-19. Methods: We conducted a cross-sectional study on 118 patients with Covid-19 who were hospitalized from 2020/2/19 to 2020/4/3 in ICU. Serum levels of electrolytes, liver enzymes, blood factors, urea, creatinine, CRP and ESR as well as anthropometric parameters and serum vitamin D concentration were measured. Results: A total of 118 patients (80 male and 38 female) was enrolled in the study (65.05±15.75 years). Only 5.08% of patients had no risk factors and 55.9% had ≥ 2 risk factors. Diabetes (44.1%) and obesity (23.7%) were more common among patients. Laboratory finding showed that 80.50% of patients had hyponatremia, but other electrolytes included K, Mg, Ca and P were normal in majority of participants as well as CBC, Cr, Urea, Alb, ALT and ALKP. The AST concentration increased in most patients (66.94%). All patients had high levels of inflammatory factors such as CRP and ESR. The mean of 25-hydroxy-vitamin D levels in participants (25.95 ± 14.56 ng/mL) was lower than its levels in general papulation. However, it was not statistically significant (P= 0.88). A significant negative correlation found between vitamin D and ALT (P= 0.02, -0.21) as well as vitamin D and CRP (P= 0.05, -0.17). Conclusion: Regarding to the regulatory role of vitamin D in immune system and low levels of vitamin D in Covid-19 infected patients, the evaluation of vitamin D levels and prescribe supplements if necessary is suggested.

In late 2019, the new Coronavirus has been identified in the city of Wuhan (China) then COVID-19 spreads like wildfire in the rest of the world. Pregnant women represent a risk category for increased abortion rates and vertical transmission with adverse events on the newborns has been recently confirmed. The scientific world is struggling for finding an effective cure for counteracting symptomatology. Today, there are many therapeutic proposes but none of them can effectively counteract the infection. Moreover, many of these compounds show important side effects not justifying their use. Scientific literature reports an immune system over-reaction through interleukins- 6 activation. In this regard, the possibility to control the immune system represents a possible strategy for counteracting the onset of COVID-19 symptomatology. Vitamin D deficiency shows increased susceptibility to acute viral respiratory infections. Moreover, Vitamin D seems involved in host protection from different virus species by modulating activation and release of cytokines. Myo-inositol down-regulates the expression of IL-6 by phosphatidyl-inositol-3-kinase pathway. Furthermore, myo-inositol is the precursor of phospholipids in the surfactant and it is applied for inducing surfactant synthesis in infants for treating respiratory distress syndrome. This review aims to summarize the evidence about COVID-19 infection in pregnant women and to encourage the scientific community to investigate the use of Vitamin D and Myo-inositol which could represent a possible preventive treatment for pregnant women or women undergoing assisted reproductive technologies.

The new coronavirus infection COVID-19 that appeared at the end of 2019 is signifi cantly different from the viral infections that existed previously. The new SARS-CoV-2 coronavirus combines two transmission routes—aerosol and oral-intestinal. The targets for this virus are both cells of the respiratory system and the human gastrointestinal tract. Along with the classical form of this disease, the so-called “gastrointestinal” form is described, in which the clinical picture is dominated by signs of damage to the gastrointestinal tract (diarrhea, vomiting, anorexia). These symptoms are detected, in general, in 20% of patients with COVID-19. More than 80% of patients have mild forms, a third of these individuals had diarrhea. Although SARSCoV-2 viral RNA is detected in faeces samples of patients with COVID-19, it does not carry an infectious onset, and not a single case of fecal-oral transmission has been confi rmed. Since the intestines are the most powerful organ of our immune system, we can introduce SARS-CoV-2 viral RNA into the gastrointestinal tract to ensure the formation of immunity to this infection.

Coronavirus disease 2019 (COVID-19) is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection, affecting millions of people worldwide due to its ease of transmission. Despite limited information on effective therapeutic options, vitamin D has been regularly reported to exert beneficial immunomodulatory effects affecting both innate and adaptive immune systems. As it is synthesized in the skin under ultraviolet radiation, population living in equatorial countries are presumed to have adequate vitamin D, however several studies have shown otherwise. This article is aimed to give an insight on the different mechanisms by which vitamin D affects our immune system in COVID-19, as well as discussing correlation of having sunlight all year round by being near the equator towards vitamin D adequacy.
