Autoantibodies Caused by COVID-19 Increase Risk of Severe Early COVID & Long COVID

A new report suggests that COVID-19 patients have increased autoantibodies, resulting in an increased risk of severe early and long COVID-19 symptoms.  Autoantibodies represent a misdirection of our natural immune response towards “self” tissue.  Researchers from Yale School of Medicine tested 194 SARS-CoV-2 infected patients for autoantibodies and found a dramatic increase in autoimmune reactivity compared to…

Vitamin D Deficiency Increases Risk of Severe COVID Infection & Mortality

More research confirms that maintaining optimal vitamin D levels is extremely important for reducing the risk of infection with SARS Cov-2. A six-week observational study of 154 people published in Nature found that 97 percent of individuals with severe COVID-19 had vitamin D deficiency (mean concentration was 14 ng/mL) compared to 33 percent of people…

Polyphenols in Green Tea, Chocolate and Other Foods May Protect Against COVID

Some of our favorite polyphenol-rich foods, including green tea, muscadine grapes, cacao, and dark chocolate appear to block an enzyme in the SARS-CoV-2 virus, inhibiting its replication. A docking simulation and in vitro study published in Frontiers in Plant Science found that these flavan-3-ol and proanthocyandin-containing foods can block and bind the function of this enzyme, or protease, which…

Melatonin May Offer Significant Protection from COVID Infection, and especially for African Americans

Supplementing with melatonin may decrease the likelihood of contracting COVID, particularly among African Americans. Researchers analyzed data from an observational study of over 26,000 people from a COVID-19 registry at the Cleveland Clinic Health System and found that melatonin use is associated with a 52% reduced likelihood of a positive SARS-CoV-2 test in African Americans.…

Two Mechanisms Potentially Improving Acquired Immunity to COVID-19: The Common Cold and Breastmilk

People who have been exposed to a seasonal “common cold” may experience less severe COVID-19 symptoms. While we’ve discussed this topic previously, a study from the Journal of Clinical Investigation reports the first clinical evidence of cross reactivity with the common cold and COVID. This is due to previous immune responses against the four endemic…

Data Emerge on “Long” COVID Characteristics and Risk Factors

Long COVID is now recognized as a post-viral syndrome of chronic debilitating symptoms that can last for months. Similar post-viral syndromes that have been observed follow other infections such as influenza, pneumonia, Epstein-Barr virus, and HIV. New data from a recent study by Kings College London of 4 million individuals in the United Kingdom indicates that: It’s relatively…

Lancet Revises Editorial Policy Following Scandal Over Hydroxychloroquine Study

Three months ago, the prestigious medical journal The Lancet published, and then later retracted, a study on the use of hydroxychloroquine for COVID-19. The retraction was prompted by questions that were subsequently raised about the integrity of the data used for analysis from a database called Surgisphere, especially when it turned out that none of…

Natural Interventions to Lower Furin Levels As a Factor in SARS CoV-2 or Role of Furin Proteases in COVID 19 & Therapeutic Interventions

Elevated furin levels are not only associated with Covid-19 but also linked to comorbidities including diabetes, obesity, and hypertension – perhaps one reason why these comorbidities are linked with worse COVID-19 outcomes. In this peer-reviewed publication, Dr. Kara Fitzgerald discusses the role of furin proteases in Covid-19 and how dietary, lifestyle, natural and pharmaceutical interventions aimed…
