Abstract
Background Targeting mucosal immunity of the gut, which is known to provide antigen processing, while avoiding excessive or unnecessary inflammation, was tested as a way to modulate COVID-19 severity. <br>
Methods Randomized open-label trial in 204 adults hospitalized with non-critical COVID-19 who received for 14 days in addition to standard of care (SOC) degalactosylated bovine glycoproteins formulations of either MAF capsules (MAF group) or M capsules (M group) or SOC only (control group).
Based on a growing body of evidence that a dysregulated innate immune response mediated by monocytes/macrophages plays a key role in the pathogenesis of COVID-19, a clinical trial was conducted to investigate the therapeutic potential and safety of oral macrophage activating factor (MAF) plus standard of care (SoC) in the treatment of hospitalized patients with COVID-19 pneumonia. Ninety-seven hospitalized patients with confirmed COVID-19 pneumonia were treated with oral MAF and a vitamin D3 supplement, in combination with SoC, in a single-arm, open label, multicentre, phase II clinical trial. The primary outcome measure was a reduction in an intensive care unit transfer rate below 13% after MAF administration.
The effects of degalactosylated whey protein on lipopolysaccharide (LPS)-induced inflammatory responses in mice were observed in comparison with intact whey protein. Intraperitoneal administration of both intact and degalactosylated whey proteins for 5 days did not affect body weight and food intake in mice. On day 6, intraperitoneal administration of LPS induced a marked decrease in body weight 4 h later. Read more >>
The hypothesis: Based on the aforementioned findings and on documented analogies between SARS-CoV-2 and HIV, we hypothesized that the reduced conversion activity of the Gc protein (human group-specific component (Gc)) into the macrophage activating factor (MAF) could have a key role in the dysregulate immune response induced by SARS-CoV-2, just like for HIV infected patients. If this hypothesis is correct, it might help to set a valid strategy of immunotherapy also based on an off-label use of GcMAF in critically ill COVID-19 patients.
