The inflammatory reaction and pathogenesis of COVID-19 may be modulated by circulating trace elements (Iron (Fe), Zinc (Zn), Copper (Cu), Manganese (Mn)) Metallothioneins (MTs). Thus, the present study aimed to investigate their relationship with clinical, biochemical, parameters in patients at early Intensive Care Unit (ICU) phase. Critically ill (n = 86) were monitored from first day ICU admission until third stay. Serum samples used assess mineral levels via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) MT differential pulse voltammetry. Levels Cu MTs significantly decreased after 3 days (p < 0.05), increasing prevalence Cu-deficient values 50% 65.3% 0.015). Fe Zn shown have a predictive value for mortality severity. suggests element deficiency risk factor during treatment COVID-19, as it is related different biochemical clinical parameters, indicating possible beneficial effect restoring proper these micronutrients.

The sustenance of human life activities depends on copper, which also serves as a crucial factor for vital enzymes. Under typical circumstances, active homeostatic mechanisms keep the intracellular copper ion concentration low. Excess ions cause excessive cellular respiration, causes cytotoxicity and cell death levels steadily rise above threshold. It is novel that mitochondrial ions, regulation. Cuproptosis now understood to play role in several pathogenic processes, including inflammation, oxidative stress, apoptosis. Copper type regulatory death(RCD).Numerous diseases are correlated with development homeostasis imbalances. One most popular areas study field cancer cuproptosis. has been discovered angiogenesis, proliferation, growth, metastasis all accumulation ions. concentrations can serve marker development.

SARS-CoV-2 infects type II pneumocytes and disrupts redox homeostasis by overproducing reactive oxygen species (ROS). N-acetyl cysteine (NAC) is a precursor of the synthesis glutathione (GSH) it restores loss associated to viral infections. The aim study evaluate effect treatment with NAC on enzymatic antioxidant system in serum from patients infected SARS-CoV-2. We evaluated activities thioredoxin reductase (TrxR), peroxidase (GPx), -S-transferase (GST), (GR) spectrophotometry concentrations (GSH), total capacity (TAC), thiols, nitrites (NO2-), lipid peroxidation (LPO) serum. activity extracellular super oxide dismutase (ecSOD) was determined native polyacrylamide gels, 3-nitrotyrosine (3-NT) measured ELISA.

Importantly, LF was found exert activities several types viruses, including certain variants. LF’s effect on COVID-19 patients seen rapid increase vitro vivo studies published, resulting model how might play role during different phases infection. Aim this narrative review two-fold: (1) highlight the most relevant findings concerning anti-viral, anti-microbial, iron-binding, immunomodulatory, microbiota-modulatory intestinal barrier properties that support health two affected organs (lungs gut), (2) explore possible underlying mechanisms governing mode action.
