Melatonin: Immune-Modulating Role in COVID-19?

 

By Krista Anderson Ross, ND | April 14, 2020



A recently published review article suggests that melatonin could play a role in combating COVID-19. The article “COVID-19: Melatonin as a potential adjuvant treatment” by Rui Zhang et al., published March 23rd 2020, suggests that the excessive inflammation, oxidation, and exaggerated immune response during COVID-19 infection contributes to the cytokine storm that progresses into acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The anti-inflammatory, anti-oxidant, and immunomodulating effects of melatonin have been shown to be protective against viral-induced ALI/ARDS. 1

Coronaviruses (CoVs) are RNA viruses that infect both humans and animals. The infection involves the respiratory, gastrointestinal, and central nervous systems. Severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) are similar infectious diseases that have caused thousands of deaths in the past two decades. 1

Cytokine Storm

Recently published research suggests a nucleotide similarity between SARS-CoVs, MERS-CoVs and SARS-CoV-2, suggesting a high genetic homology. In SARS-CoV and MERS-CoV infected animal models, severe inflammatory and immune responses may activate a “cytokine storm,” i.e.: apoptosis of epithelial cells and endothelial cells leading to vascular leakage and abnormal T cell and macrophage responses, inducing ALI/ARDS, and even death. This cytokine storm appears to prevail in patients with COVID-19 based on genetic homology and pathologic features of the infected lungs. In the blood of patients with COVID-19, there was a marked increase in the inflammatory markers IL-1B, IFN-y, IP-10, MCp-1, IL-4, and IL-10 compared to SARS patients. Additionally, COVID-19 patients present with suppressed immune function marked by hypo-albuminemia, lymphopenia, neutropenia, and decreased percentage of CD8+ T cells. In summary, the excessive inflammation, depressed immunity, and active cytokine storm appears to contribute to the pathogenesis of COVID-19. 1, 2, 3, 6

Indirect Anti-viral Actions

Melatonin has indirect anti-viral actions due to its anti-inflammatory, anti-oxidant, and immune-enhancing features. Melatonin has been shown to reduce viremia, paralysis, and death in mice infected with viral encephalitis; and has led to downregulation of acute lung oxidative injury, pro-inflammatory cytokine release, and inflammatory cell recruitment in respiratory syncytial virus models. These findings support a rationale for melatonin use in viral diseases. Additionally, the anti-inflammatory, anti-oxidant, and immunomodulating actions of melatonin support its potential attenuation of COVID-19 infection. 1,4, 5

Anti-Inflammation

Melatonin exerts anti-inflammation effects through various pathways. Melatonin suppresses NF-kB activation in ARDS and downregulates NF-kB activation in T cells and lung tissue. Conversely, melatonin stimulates NF-E2 related factor 2 (Nrf2), crucial in protecting against lung, liver, and cardiovascular injury. Inflammation generally involves an increase in the production of the cytokines and chemokines TNF-α, IL-1β, IL-6, and IL-8, whereas melatonin has been shown to reduce them. 1, 9, 10, 11

Immunomodulation

NOD-like receptor 3 inflammasome (NLRP3) is part of the innate immune response during lung infection. It is activated by viruses to amplify inflammation. NLRP3 is correlated to lung diseases caused by infection, including influenza A virus, syncytial virus, and bacteria. Melatonin has been shown efficacious in inhibiting NLRP3-mediated lung injury by reducing the infiltration of macrophages and neutrophils in lung tissue. 1, 7, 8

Melatonin enhances the immune response by improving proliferation and maturation of natural killer cells, T and B lymphocytes, granulocytes, and monocytes in both bone marrow and other tissues. In macrophages, antigen presentation is augmented after the application of melatonin, including the up-regulation of complement receptor 3, MHC class I and class II, and CD4 antigens. 1, 12

Melatonin effects on cytokine levels in humans

While there are no research studies related to the use of melatonin in patients with COVID-19, the use of melatonin has been shown promising in other diseases with an increased level of inflammation. At doses of 6 mg/d and 25mg/d, respectively, melatonin has been shown to decrease serum levels of IL-6, TNF-α, and hs-C-reactive protein (hs-CRP) in patients with diabetes mellitus and periodontitis, and promotes a significant reduction in serum concentrations of TNF-α, IL-6, IL-1β and lipoperoxides in patients with MS. Additional studies of melatonin at intakes of 5-10mg/d have been shown to decrease many of the same inflammatory cytokines found in COVID-19. 1, 13, 14, 15

Short-term use of melatonin has been deemed safe, even at higher than physiologic doses (physiologic doses being in the 0.5 – 1mg range). While the safety of melatonin has been verified in many human studies, its effect when given to COVID-19 patients remains unknown and should be monitored closely. Its use in experimental animal models and human studies has continuously documented its efficacy and safety.

Patients prone to viral infections or dealing with inflammation-based chronic conditions may benefit from melatonin usage. Melatonin testing can reveal the baseline status of this important anti-inflammatory, immune-modulating hormone, providing a framework for supplementation.

Dr. Anderson-Ross will be presenting Melatonin: Synthesis, Sleep and Supplementation on May 6, 2020. She will review the various roles of melatonin, and discuss current testing and treatment strategies. Case studies will be discussed. Dr. Anderson-Ross will also briefly review the literature of melatonin’s immune modulating and anti-viral properties, and potential implications for COVID-19. A live Q&A session will follow the main presentation. Register for the May 6 webinar here.
