Abstract

Ascorbic acid (vitamin C) elicits pleiotropic effects in the body. Among its functions, it serves as a potent anti-oxidant, a co-factor in collagen and catecholamine synthesis, and a modulator of immune cell biology.Furthermore, an increasing body of evidence suggests that high-dose vitamin C administration improves hemodynamics, end-organ function, and may improve survival in critically ill patients. This article reviews studies that evaluate vitamin C in pre-clinical models and clinical trials with respect to its therapeutic potential.

 



INTRODUCTION

Vitamin C is one of the most well-known essential nutrients and is believed by many to confer a litany of health benefits (Figure 1). The Nobel Prize Winner Linus Pauling may have been the foremost ambassador to date who suggested that vitamin C would enhance cardiovascular health, improve the body’s immune function to overcome infections, and even help abate cancer[1–4]. These health claims created significant controversies that lasted for decades. While many of Pauling’s “more is better” claims have not been supported by rigorous scientific investigation, a growing number of benefits of vitamin C administration have been identified for medical treatment, including in the field of critical care. This mini-review will examine the evidence in support of vitamin C administration for critically ill patients and provide general recommendations for use by intensive care unit practitioners.

Unexpected Early Response in Oral Bioavailability of Ascorbic Acid

Introduction

Repeatable and inexpensive experiments have cast doubt on the hypothesis that only 200 mg of vitamin C taken orally can be absorbed. We measured vitamin C blood plasma levels every minute for the first 40 minutes using a novel approach.  By contrast to the prevailing paradigm, our results suggest that up to 4,000 mg of ascorbic acid taken by mouth can produce the same rapid increase in plasma concentration as an intravenous infusion.Previous studies did not sample blood levels during this early stage of oral intake.  We confirmed that specific glucose meters do provide a reproducible measure of ascorbate (vitamin C) concentration. Researchers had previously demonstrated the ability of specific glucose meters to measure high levels of ascorbate during and after intravenous vitamin C infusions (IV/C).1Our initial aim was to confirm the adequacy of the method. However, we observed that the meters are responsive to lower oral intakes and discovered an initial high rate of oral absorption,which may add to understanding of the pharmacokinetics of ascorbate and have clinical and nutritional implications.

The Tension Between Public Health & Patents In The Era Of COVID-19

https://www.statnews.com/2020/04/14/patents-public-health-tension-covid-19/

The Covid-19 pandemic, devastating as it is, is producing some triumphs of collaborative research and innovation, as everyone from the World Health Organization to national laboratories, pharmaceutical companies, and Facebook groups of engineers race to fight the virus. But lurking behind this remarkable work is a threat: Some individuals or companies may exploit patents to profiteer off the crisis and could slow these innovative efforts to a crawl.

In this time of crisis, lawmakers must be wary of patents and be flexible and proactive in using the many legal tools available to check their harmful use. (See link for article)

**Comment**

Great reminder of an all important topic Lyme/MSIDS patients are all too aware of: conflicts of interests slowing or even stopping true scientific progress.

Recently, regarding COVID-19, I posted that the Chinese are trying to patent the anti-viral, Remdesivir:  https://madisonarealymesupportgroup.com/2020/04/17/live-video-chat-remdesivir-data-chicago-hospital-seeing-rapid-recoveries-patients-discharged-in-less-than-a-week/There is currently a clinical trial for Remdesivir in which they are finding:

rapid recoveries in fever and respiratory symptoms, with nearly all patients discharged in less than a week.

A similar effect was found in rhesus monkeys:  https://www.nih.gov/news-events/news-releases/antiviral-remdesivir-prevents-disease-progression-monkeys-covid-19

Regarding Lyme/MSIDS, microbiologist Tom Greer recently wrote an excellent letter outlining this problem of conflicts of interests and patents: https://madisonarealymesupportgroup.com/2020/04/19/letter-to-chronic-lyme-denialists-from-a-microbiologist/

A while back, I too wrote an article highlighting the problems with the faulty research that continues to be done – ignoring an entire LARGE subset of people who have remaining symptoms:  https://madisonarealymesupportgroup.com/2019/02/22/why-mainstream-lyme-msids-research-remains-in-the-dark-ages/  The authorities continue to fixate on the acute stage of the disease as well as insist upon having positive blood serology when research has proven Lyme tests relying upon antibodies to be worthless. They also insist that patients have the EM rash to enter studies, when research also shows many never get a rash.

Excerpt:

The 1994 serodiagnostic testing guidelines predated a full understanding of key B. burgdorferi antigens and have a number of shortcomings. These serologic tests cannot distinguish active infection, past infection, or reinfection.

Lyme Patients Speak Out on Having COVID-19

__________________________
For another Chronic Lyme patient who had COVID-19:

The first patient to speak is Representative Karen Whitsett who credits President Trump’s promotion of a malaria drug, hydroxychloroquine, with her recovery from coronavirus. Other COVID-19 survivors also speak after her at the White House. During their informal discussions, Rep. Whitsett, who had a severe case of  COVID-19, brought up her chronic Lyme disease as an underlying condition. Throughout the 41-minute meeting, President Trump highlighted how serious and devastating Lyme disease is, stating that it “can kill you.”

Although the following patient DID NOT have COVID-19, her Lyme disease herxes made her think she might have had it.

Is it COVID-19 or a Lyme disease herx? One woman’s story.
