Brief Summary:
Infections with SARS-CoV-2 result in a systemic disease with a variety of outcomes from no symptoms to severe and diverse pathologies Therefore it is important to identify risk factors determining COVID-19 severity especially if those factors might be adjusted allowing early and effective therapeutic interventions Zinc is a trace element essential for human health Zinc deficiency is common in old adults vegetarians and patients with chronic inflammatory diseases This condition causes immune dysfunction leading to increased risk of inflammatory and infectious diseases including acquired immune deficiency syndrome measles malaria tuberculosis and pneumonia Besides zinc has a direct antiviral activity against specific viruses like rhinovirus HCV herpes simplex virus In this scenario it has been shown that zinc supplementation has benefits on the recurrence and persistence of acute and chronic viral infections like common cold or HCV HBV Moreover our team has recently done an observational study with 249 COVID-19 patients that showed how COVID-19 patients with lower plasma zinc content had worse prognosis increased time of hospitalization and mortality
Therefore the main aim of the project is to explore the therapeutic benefit of zinc supplementation for COVID-19 patients and to determine the cellular and molecular basis of the effect of Zn levels on SARS CoV-2 infections For that purpose the investigators will run a clinical trial supplementing with zinc COVID-19 patients Moreover the investigators will carry out experiments to understand the association between zinc nutritional status and SARS-Cov-2 infection progression in cellular and animal models
Given the current knowledge about zinc supplementation toxicity and dosage the investigators expect that recommendations derived from this study will be rapidly applied by physicians and public health decision makers The results of these studies will be used as a guideline to administer zinc supplements in COVID-19 patients in order to reduce disease severity and mortality Moreover the experiments will clarify whether zinc supplementation as a prophylaxis strategy is useful to protect the population at risk of zinc deficiency more than 20 worldwide Finally considering the new knowledge that this project will generate about the role of zinc in immune responses and viral expansion the investigators expect that our results will help researchers and physicians to design novel strategies to boost specific immune cell subpopulations against SARS-CoV2 infection Thus this knowledge could be used long-term for designing medicines against SARS-CoV-2 and other viral infections

Detailed Description:
Background The essential micronutrient zinc balances immune responses to infections and additionally directly inhibits some viruses The investigators have recently shown a robust correlation between serum zinc levels SZLand COVID-19 outcome in patients and a direct effect of zinc levels on SARS-CoV-2 expansion in cell cultureThese results suggest that SZL might represent an important risk factor for COVID-19 severity whose adjustment would constitute an early and cost-effective therapeutic intervention
Objectives To explore the therapeutic benefit of zinc supplementation for COVID-19 patients and to determine the cellular and molecular basis of the effect of zinc levels on SARS-CoV-2 infections
Methodology A randomized clinical trial supplementing COVID-19 patients with zinc will be carried out and viral loads inflammatory and novel zinc-related clinical markers and SARS-CoV-2-specific T- and B-cell Responses monitored Humanized-ACE2-mice models will be used to address causal-effect associations between zinc levels and SARS-CoV-2 infection Infections of human Calu-3 cells will be used to decipher the direct antiviral action of zinc on SARS-CoV-2 life cycle Expected results The investigators will generate a clear insight into zinc functioning in COVID-19 patients that might provide a therapeutic guideline immediately applicable to reduce the severity of SARS-CoV-2 pathogenicity and possibly other virus infections
