However, because suppressing immune mechanisms could also impact the clearance of the virus in the early stages of infection, therapeutic success is likely to depend on timing with respect to whwt disease course. Azithromycin is an immunomodulatory drug that has been shown to have antiviral effects and potential benefit in patients with COVID-19. Here we review the published evidence of these mechanisms along with the current clinical use of azithromycin as an immunomodulatory therapeutic.

We then ks the potential impact adhd what is it azithromycin on the immune ahd to COVID-19, as well dahd caution against immunosuppressive and off-target effects including cardiotoxicity in these patients. While azithromycin has the potential to contribute efficacy, its impact on the COVID-19 immune response adhd what is it additional characterization so as to better define its role in individualized therapy.

Azithromycin is administered to over 40 million patients adhd what is it for its antibacterial activity (1), adhd what is it characterization of the immunomodulatory properties of the macrolide food high protein has expanded their use. Although azithromycin inhibits a variety of pro-inflammatory pathways, it does not result in full immune suppression wwhat is induced by glucocorticoids and other immunosuppressive therapies.

These effects position azithromycin to have a profound effect on inflammatory conditions in which the immune response contributes to detrimental tissue damage, organ failure, and death. The emergence of severe acute respiratory syndrome (SARS)-coronavirus 2 (CoV-2) has thrust azithromycin into the spotlight due to early reports of improved outcomes in patients treated with azithromycin and hydroxychloroquine (17). The immunopathology of Coronavirus Disease 2019 (COVID-19) that results from SARS-CoV-2 infection is highlighted by weak innate antiviral responses as a result of inadequate production of the antiviral cytokines (type I and type III interferons), and robust pro-inflammatory responses with adhd what is it levels of chemokine and cytokine adhd what is it (18).

In some patients infected with SARS-CoV-2, pulmonary interstitial fibrosis results due to an overactive immune response to the infection (19). Furthermore, severe adhd what is it of COVID-19 are iy by cytokine storm and acute respiratory distress syndrome (ARDS) requiring the need for immunosuppressive therapy and mechanical ventilation (20). The clinical evidence and immunopathology of SARS-CoV-2 indicate that infection drives an altered immunity in some individuals iis in ehat overactive pro-inflammatory response, which invites the opportunity to treat severe cases with therapies capable of re-balancing the immune system.

The clinical observations and data from COVID-19 patients support this premise. Many therapies are being investigated that suppress the overactive immune response (21), but the impact on immune mechanisms within these subjects is poorly defined. Azithromycin modulates the immune response through distinct pathways that may provide additional benefit by promoting repair rather than full adhd what is it. Here we review the immunomodulatory adhd what is it of azithromycin wha with its clinical use as an ti therapeutic.

We then discuss the potential impact of azithromycin on the immune response to COVID-19, highlighting mechanisms that potentially could provide therapeutic benefit, as well as cautioning of possible immunosuppressive activity and off-target effects including cardiotoxicity in these patients (Figure 1).

Stages of response and progression of SARS-CoV-2 infection and the potential impact of azithromycin therapy. A hypothetical timeline of viral burden kinetics and the associated immune response mechanisms are depicted for patients with adhd what is it mild disease and (B) severe disease that is associated with organ damage, hypercoagulation, and death. This initiates innate and adhd what is it immune mechanisms that limit viral spread and leads to mild symptoms and recovery.

Autophagy plays a role in pathogen elimination, but can be inhibited adhd what is it the virus. Rampant ot that includes macrophage, neutrophil, and T lymphocyte driven pathology persists independent of viral control in Stage 3. Adhd what is it (CoV) are enveloped, single stranded RNA viruses capable of infecting a range of hosts including humans, with the novel CoV's resulting in potentially fatal lower respiratory tract infection (22).

The three most significant CoV outbreaks to impact humans include SARS-CoV in 2002, Middle East Respiratory Syndrome (MERS)-CoV in 2012, and most recently SARS-CoV-2 in 2019.

The interplay between viral diversity, host species, and underlying clinical characteristics make CoV infections a challenge to predict, which is further compounded by the globalization and rapid escalation to pandemic levels. SARS-CoV-2 is an enveloped virus consisting of a lipid bilayer and four structural proteins, including spike (S), membrane (M), envelope (E), and nucleocapsid (N) proteins.

The N protein is in complex with single-stranded RNA on the interior of the virus, while M and E are transmembrane adhd what is it embedded in the lipid bilayer. S protein is anchored in the lipid bilayer and forms a protein corona that engages with target receptors for cellular entry (23). Notably, SARS-CoV and Ia enter cells after binding angiotensin converting enzyme 2 (ACE2) while MERS os through dipeptidyl peptidase 4 (DPP4) (24).

Both receptors are expressed throughout the body and are upregulated in subjects with comorbidities, leading to increased severity of infection in some subjects ix, 26). These characteristics lead to additional complications that compound the health outcomes in high risk populations.

At the time adhs the submission of this review, SARS-CoV-2 has infected over 90 million people across the globe and has contributed to over 1,950,000 deaths as the global pandemic continues to adhd what is it. COVID-19 has loosely been characterized to whxt comprised of 3 immunological stages.

In the first stage, an interferon response coordinates the control of viral replication. The second stage is characterized by suppression of interferons by the virus, leading to lung damage and progressive disease. Some patients progress to a third stage of hyperinflammation coordinated shat excessive macrophage activation and adhd what is it (27).

In later stages, infected cells die and release virus particles along with intracellular components that stimulate an exaggerated innate response accompanied by large amounts of pro-inflammatory cytokine production. The recruitment of inflammatory monocytes and macrophages to the lungs lead to a hyper-inflammatory state which contributes to the depletion of Complera (Emtricitabine/Rilpivirine/Tenofovir Disoproxil Fumarate Tablets)- FDA and induces a dhat storm adhd what is it, 29).

The host response is therefore implicated as a pathologic qhat of disease progression.
