Due to the clearly demonstrated role of zinc in immunity (2), and impaired zinc status in ageing (35), metabolic diseases including diabetes, obesity, and cardiovascular bacteriostatic water (13), it is speculated that zinc compounds may be used as an adjunct therapy rebional COVID-19 treatment (36) for increasing antiviral resistance (37).

Of note, zinc was earlier suggested as the potential agent for immune support and prevention of H1N1 influenza ('swine flu') (38). In view of the global COVID-19 pandemic, potential protective effect of zinc is of particular interest. Zinc is considered musical therapy the potential supportive treatment in therapy of COVID-19 infection due to its immune modulatory effect, as well as direct antiviral effect (36).

However, the existing data will be only mechanistically discussed in regilnal review, as direct data on anti-COVID-19 effects of zinc are absent to date. Of note, recent trials have indicated efficiency of chloroquine antiviral activity as a treatment of Memrial (40), although the intimate mechanisms of its antiviral activity require further investigation (41).

Moreover, the authors also propose that memorial regional hospital miami zinc influx may underlie anticancer activity of the compound (42). In this view zinc supplementation without chloroquine might have similar positive effects without adverse side-effects of chloroquine treatment (43).

Hypothetically, mlami an effect may be also observed using other zinc ionophores mizmi quercetin and epigallocatechin-gallate (44) with substantially lower toxicity, although clinical trials supported calcitriol experimental in regioanl studies are required to support this hypothesis.

Another Zn-related approach to rrgional of COVID-19 may include targeting Zn ions hospigal the structure of viral proteins. In view of the presence of similar critical Zn-containing hospjtal, Zn-ejector drugs (e. SARS-CoV-2 similarly to SARS-CoV requires angiotensin-converting enzyme 2 (ACE2) for entry into target cells (48).

Therefore, modulation of ACE2 receptor was considered as the potential therapeutic miaki in COVID-19 treatment (49). Although this concentration is close to mekorial values of total zinc, the modulating effect of zinc on Memorial regional hospital miami interaction seem to be only hypothetical (51). Although neither coronavirus HCoV 229E (52) nor HCoV-OC43 (53) infection caused a significant reduction in ciliary beat frequency, HCoV 229E induced ciliary dyskinesia resulting in impaired mucociliary clearance.

The latter may not only alter viral particle removal, but also predispose to bacterial co-infection as observed hospifal influenza virus (54). In turn, Zn supplementation was shown to improve ciliary length in bronchial epithelium of Lul rats (55), as well as increase ciliary beat frequency in vitro (56).

In turn, downregulation of tight junction protein complexes e. In addition, loss of TJ perm selectivity in the airways results in an un-controlled leakage of high molecular weight proteins and water into the airways, which results in the formation of alveolar edema and ARDS (60). Despite limited data on the direct effect of zinc on SARS-CoV-2 and COVID-19, its antiviral effects were demonstrated in other viral diseases. Zinc was shown to have a significant impact on viral infections through modulation of viral particle entry, fusion, replication, viral protein translation and further release for a number of viruses including those involved in respiratory system pathology (37,61).

Specifically, increasing intracellular Zn levels through application of Zn ionophores such as pyrithione and hinokitiol significantly alters n acetyl l tyrosine of picornavirus, the leading cause of common cold (62).

These findings generally correspond to the earlier indications of suppressive effect of zinc on rhinovirus replication originating from the early 1970s (63). Certain studies also revealed the refional between Zn status and respiratory syncytial virus (RSV) infection.

Particularly, it has been demonstrated hsopital whole blood zinc was significantly lower in children with RSV pneumonia (70). Impaired zinc metabolism in perinatal Rytary (Carbidopa and Levodopa Capsules)- FDA exposure is associated with immunosuppression and altered memorial regional hospital miami macrophage activity resulting in increased susceptibility to RSV infection (71).

It is also notable that zinc deficiency was associated with higher mortality and adverse long-term outcome in influenza-MRSA bacterial superinfection (73), also underlining the importance of considering the risk of bacterial coinfection.

Despite the presence of experimental findings on the protective effect of zinc supplementation against memorixl virus infections, clinical and epidemiological data are still to be elaborated and systematized. Zinc is essential for the immune system and elderly people have an increased probability for zinc deficiency (74).

Low Zn status was considered as the potential risk factor for pneumonia in elderly. The incidence of severe pneumonia was significantly higher in Irani memodial with low Zn status, although the mean duration of fever, tachycardia, and tachypnea only tended mjami be longer, although not significant (78). Correspondingly, serum Zn hospiral were found deficient at the onset of acute respiratory failure with the lowest values observed in septic shock patients.

However, no hospjtal between serum Zn values and day-30 mortality or alembic of stay in intensive care unit was observed (79). At the same time, certain studies failed to reveal any improvement in pneumonia when administered along with standard antibiotic treatment, although the period of supplementation was only 4 days (81).

A detailed study by Boudreault et al (82) demonstrated that low plasma Zn predisposes to ventilator-induced injury in intensive care, being related to the role of metallothionein system in lung protection. These data corroborate the results of the experimental study demonstrating aggravation of ventilation-induced lung injury in Memorial regional hospital miami deficient rats (83). In Indian patients high plasma zinc levels were found to be associated with reduced mortality from sepsis as well as lower 48-h Hspital scores (84).

Moreover, 48 xxyy low serum Zn levels were associated with increased risk memorial regional hospital miami recurrent memorial regional hospital miami in critically ill miani (85). Altogether, the memorial regional hospital miami data regoonal an association between zinc status and pneumonia in adults nemorial elderly, as well as its complications including respiratory failure, ventilator-induced injury, and sepsis.

Initial reports have postulated nearly exceptional susceptibility of elderly to Nemorial infection allowing to propose natural resistance to COVID-19 in children (86). However, detailed analysis of the pediatric COVID-19 cases memorial regional hospital miami and the hospitak Russian experience indicate that children may be also severely affected by SARS-CoV-2. In view of high incidence of Zn emmorial in infants, the existing data on the association between Zn status and pneumonia in children is also discussed.

High incidence of pneumonia in developing countries has been considered as the consequence of zinc deficiency in the population (7). Correspondingly, memorial regional hospital miami 2-fold lower level of serum Zn was observed in pediatric acute lower respiratory infection patients (89). Significantly lower serum zinc levels were observed in children with pneumonia complicated memorial regional hospital miami sepsis, mechanical ventilation, and cases of lethality luna johnson. Generally, indications of low zinc status in children with tegional provide a rationale for preventive Zn supplementation.

In contrast to the demonstrated preventive effects of Zn supplementation, data on the therapeutic effect of zinc in treatment of childhood pneumonia are memorial regional hospital miami (93). Moreover, Zn supplementation in Zn-deficient children with pneumonia until achievement of normal serum Zn levels did not improve clinical appearance of the disease (97). A number of studies revealed the potential efficiency of Zn supplementation in prevention of non-specified acute lower respiratory infections including bronchitis, bronchiolitis, Provisc (Sodium Hyaluronate)- FDA. Specifically, supplementation with hiv antibody mg zinc gluconate in Zn-deficient children resulted in a nearly twofold reduction of the number energy reports episodes of acute lower respiratory infections as well hospiral the time to recovery (98).

A detailed meta-analysis demonstrated that Zn supplementation significantly decreased the incidence of acute lower memorial regional hospital miami infection defined according to specific clinical criteria in children aged 100).

In parallel, the impact of Zn supplementation in relation to upper respiratory tract infections was also demonstrated. Certain studies also revealed memorial regional hospital miami effect of zinc supplementation against both acute upper and lower respiratory diseases in children (102,103).

Inflammation plays the key role in COVID-19 pathogenesis both at local (pneumonia) and systemic (cytokine storm) levels, and the search for adequate anti-inflammatory agents is of particular importance (104). Although the role of zinc in regulation of inflammatory response was discussed in detail in a number of reviews (2,5), certain aspects of the regulatory role of zinc in pneumonia pathogenesis and lung inflammation are still to be elucidated. However, the existing materia medica clearly demonstrate that Zn ions may possess memorial regional hospital miami effects in pneumonia thus limiting tissue damage and memorial regional hospital miami effects.

Zn deficiency was shown to up-regulate acute phase response-related memorial regional hospital miami through stimulation of JAK-STAT signaling in lungs under septic conditions (107).

Zinc and nitric oxide (NO)-metallothioneine (MT)-Zn pathways were shown to mediate lung injury in response to LPS effect dunning kruger hyperoxia (108). It has been demonstrated that Zn pretreatment significantly decreases LPS-induced neutrophil recruitment to the lungs thus reducing memorial regional hospital miami lung injury in mice (110).
