Scientists from Israel and Iceland recently suggested that an extract of spirulina algae has the potential to reduce the chances of COVID-19 patients developing a serious case of the disease. Here is the abstract of their paper:
An array of infections, including the novel coronavirus (SARS-CoV-2), trigger macrophage activation syndrome (MAS) and subsequently hypercytokinemia, commonly referred to as a cytokine storm (CS). It is postulated that CS is mainly responsible for critical COVID-19 cases, including acute respiratory distress syndrome (ARDS). Recognizing the therapeutic potential of Spirulina blue-green algae (Arthrospira platensis), in this in vitro stimulation study, LPS-activated macrophages and monocytes were treated with aqueous extracts of Spirulina, cultivated in either natural or controlled light conditions. We report that an extract of photosynthetically controlled Spirulina (LED Spirulina), at a concentration of 0.1 µg/mL, decreases macrophage and monocyte-induced TNF-α secretion levels by over 70% and 40%, respectively. We propose prompt in vivo studies in animal models and human subjects to determine the putative effectiveness of a natural, algae-based treatment for viral CS and ARDS, and explore the potential of a novel anti-TNF-α therapy.
The Jerusalem Post reported that the research was conducted in a MIGAL laboratory in northern Israel with algae grown and cultivated by the Israeli company VAXA, which is located in Iceland. VAXA received funding from the European Union to explore and develop natural treatments for coronavirus. Iceland’s MATIS Research Institute also participated in the study.
In a small percentage of patients, infection with the coronavirus causes the immune system to release an excessive number of TNF-a cytokines, resulting in what is known as a cytokine storm. The storm causes acute respiratory distress syndrome and damage to other organs, the leading cause of death in COVID-19 patients. “If you control or are able to mitigate the excessive release of TNF-a, you can eventually reduce mortality,” said Asaf Tzachor, a researcher from the IDC Herzliya School of Sustainability and the lead author of the study. During cultivation, growth conditions were adjusted to control the algae’s metabolomic profile and bioactive molecules. The result is what Tzachor refers to as “enhanced” algae.
Tzachor said that despite the special growth mechanism, the algae are a completely natural substance and should not produce any side effects. Spirulina is approved by the US Food and Drug Administration as a dietary substance. It is administrated orally in liquid drops. “This is natural, so it is unlikely that we would see an adverse or harmful response in patients as you sometimes see in patients that are treated with chemical or synthetic drugs,” he said. The algae have been shown to reduce inflammation. Tzachor said that if proven effective, spirulina could also be used against other coronaviruses and influenza. “If we succeed in the next steps,” said Dr. Dorit Avni, director of the laboratory at MIGAL, “there is a range of diseases that can be treated using this innovative solution – as a preventative treatment or a supportive treatment.”
This is undoubtedly interesting, and one can only hope that their research is successful. However, it is a far cry from what some journalists are already making of the news. One headline read: “Scientists Discover ‘All-Natural’ COVID Treatment That Can Prevent ‘Cytokine Storm’ In Severe Patients.”
