COVID-19 tied to muscle-weakening disease; vaping risk documented

COVID-19 tied to muscle-weakening disease; vaping risk documented

Published

(Reuters) – The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

Neuromuscular disease may be triggered by COVID-19

Researchers have added the muscle-weakening disease myasthenia gravis to the list of neurological problems linked to severe COVID-19. Tremors, seizures, impaired consciousness and other nervous system issues already have been tied to severe COVID-19. In some instances, the virus appears to trick the body into attacking the brain by triggering the immune system to produce so-called autoantibodies, which mistakenly target a person’s own tissues or organs. In myasthenia gravis, autoantibodies attack nerve connections to muscles, and skeletal muscles involving breathing and moving parts of the body become weak after activity. On Monday in the journal Annals of Internal Medicine, doctors described three patients without previous neurological or autoimmune disorders whose symptoms of myasthenia gravis began within a week after fevers related to COVID-19 started. The time from the coronavirus infection to the beginning of myasthenia gravis symptoms “is consistent with the time from infection to symptoms in other neurologic disorders triggered by infections,” the researchers said. They added that the findings add to “the growing evidence of other neurologic disorders with presumed autoimmune mechanisms after COVID-19 onset.” (bit.ly/2PPI1wo)

Vaping by young people linked to higher COVID-19 risk

Vaping appears to be tied to markedly increased risks for getting COVID-19 among U.S. teens and young adults. Researchers analyzed nationally representative survey data collected in May from 4,351 participants ages 13-24 years in a study published on Tuesday in the Journal of Adolescent Health. Those who used both cigarettes and e-cigarettes in the previous 30 days were 4.7 times more likely to report having experienced COVID-19 symptoms compared with those who never smoked or vaped. Among participants who tested for COVID-19, those who used just e-cigarettes were five times more likely to report a positive test. Those who had ever used both e-cigarettes and cigarettes were seven times more likely to be diagnosed with COVID-19. Dr. David Christiani of Harvard T.H. Chan School of Public Health, who was not involved in the research, told Reuters there are many reasons why people who vape would be at increased risk of getting COVID-19. Studies have shown that “vaping liquids impair local immunity in the nose and the rest of the respiratory tract. Once those defenses are impaired, it’s going to make people more viable to infection,” Christiani said. Also, the study authors noted, vaping involves repeated touching of the mouth and face, which is associated with the spread of the virus. (reut.rs/33QGZZu; bit.ly/2XQR9oX)

Face masks could someday help diagnose illness

Some face masks are effective at limiting the spread of COVID-19, some are not – and some, researchers said, might eventually help diagnose illnesses unrelated to the coronavirus. Researchers reported in the journal Science Advances that N95 masks are most effective, as long as they do not have a valve that lets the wearer’s exhaled breath escape. Next most effective are surgical masks, followed by multiple-layer cotton masks. Bandanas only minimally curb the escape of exhaled droplets. Fleece fabrics worn around the neck and pulled over the face “seemed to disperse the largest droplets into a multitude of smaller droplets” that remain airborne longer, so they “might be counterproductive,” the researchers said. A separate report in the journal Analytical Chemistry explains that while molecules in exhaled breath can reveal disease, collecting enough molecules to diagnose a problem requires breathing into tubes or bags. But a specific kind of fiber insert placed inside a mask can collect enough molecules while wearers go about their usual activities. After volunteers wore the masks with the inserts, examining the fiber insert using mass spectrometry let researchers see even trace amounts of exhaled particles. (bit.ly/33RR2gR; bit.ly/2XX6qVA)

Certain immune responses may contribute to severe COVID-19

Researchers who compared innate immune responses – the body’s first line of defense – in patients with coronavirus infections and in healthy people found multiple differences that could shed light on COVID-19 and why some cases become so severe. There were differences, for example, in the amounts and functioning of various types of cells in blood, in gene activity in cells isolated from blood, and in levels of inflammatory molecules. In particular, three molecules that were elevated in severely ill patients – called LIGHT, Oncostatin-M and EN-RAGE – are linked with lung inflammation but have not previously been seen in COVID-19 patients, the researchers reported on Tuesday in the journal Science. Severely ill patients also had bacterial debris, such as bacterial DNA and cell-wall materials, in their blood. The more debris, the sicker the patient, and the more inflammatory substances circulating in the blood. But surprisingly, “although there were enhanced levels of inflammatory molecules in plasma, the blood cells themselves were in a state of functional sluggishness, and failed to respond efficiently to stimulation,” senior author Bali Pulendran of Stanford University told Reuters. Overall, Pulendran said, “the study yields mechanistic insights and potential therapeutic targets for COVID-19.” (bit.ly/31NSZs7)

International

Removing antimicrobial resistance from the WHO’s ‘pandemic treaty’ will leave humanity extremely vulnerable to future pandemics

Drug-resistant microbes are a serious threat for future pandemics, but the new draft of the WHO’s international pandemic agreement may not include provisions…

In late May, the latest version of the draft Pandemic Instrument, also referred to as the “pandemic treaty,” was shared with Member States at the World Health Assembly. The text was made available online via Health Policy Watch and it quickly became apparent that all mentions of addressing antimicrobial resistance in the Pandemic Instrument were at risk of removal.

Work on the Pandemic Instrument began in December 2021 after the World Health Assembly agreed to a global process to draft and negotiate an international instrument — under the Constitution of the World Health Organization (WHO) — to protect nations and communities from future pandemic emergencies.

Since the beginning of negotiations on the Pandemic Instrument, there have been calls from civil society and leading experts, including the Global Leaders Group on Antimicrobial Resistance, to include the so-called “silent” pandemic of antimicrobial resistance in the instrument.

Just three years after the onset of a global pandemic, it is understandable why Member States negotiating the Pandemic Instrument have focused on preventing pandemics that resemble COVID-19. But not all pandemics in the past have been caused by viruses and not all pandemics in the future will be caused by viruses. Devastating past pandemics of bacterial diseases have included plague and cholera. The next pandemic could be caused by bacteria or other microbes.

Antimicrobial resistance

Antimicrobial resistance (AMR) is the process by which infections caused by microbes become resistant to the medicines developed to treat them. Microbes include bacteria, fungi, viruses and parasites. Bacterial infections alone cause one in eight deaths globally.

AMR is fueling the rise of drug-resistant infections, including drug-resistant tuberculosis, drug-resistant pneumonia and drug-resistant Staph infections such as methicillin-resistant Staphylococcus aureus (MRSA). These infections are killing and debilitating millions of people annually, and AMR is now a leading cause of death worldwide.

Without knowing what the next pandemic will be, the “pandemic treaty” must plan, prepare and develop effective tools to respond to a wider range of pandemic threats, not solely viruses.

Even if the world faces another viral pandemic, secondary bacterial infections will be a serious issue. During the COVID-19 pandemic for instance, large percentages of those hospitalized with COVID-19 required treatment for secondary bacterial infections.

New research from Northwestern University suggests that many of the deaths among hospitalized COVID-19 patients were associated with pneumonia — a secondary bacterial infection that must be treated with antibiotics.

Treating these bacterial infections requires effective antibiotics, and with AMR increasing, effective antibiotics are becoming a scarce resource. Essentially, safeguarding the remaining effective antibiotics we have is critical to responding to any pandemic.

That’s why the potential removal of measures that would help mitigate AMR and better safeguard antimicrobial effectiveness is so concerning. Sections of the text which may be removed include measures to prevent infections (caused by bacteria, viruses and other microbes), such as:

  • better access to safe water, sanitation and hygiene;
  • higher standards of infection prevention and control;
  • integrated surveillance of infectious disease threats from human, animals and the environment; and
  • strengthening antimicrobial stewardship efforts to optimize how antimicrobial drugs are used and prevent the development of AMR.

The exclusion of these measures would hinder efforts to protect people from future pandemics, and appears to be part of a broader shift to water-down the language in the Pandemic Instrument, making it easier for countries to opt-out of taking recommended actions to prevent future pandemics.

Making the ‘pandemic treaty’ more robust

Measures to address AMR could be easily included and addressed in the “pandemic treaty.”

In September 2022, I was part of a group of civil society and research organizations that specialize in mitigating AMR who were invited the WHO’s Intergovernmental Negotiating Body (INB) to provide an analysis on how AMR should be addressed, within the then-draft text.

They outlined that including bacterial pathogens in the definition of “pandemics” was critical. They also identified specific provisions that should be tweaked to track and address both viral and bacterial threats. These included AMR and recommended harmonizing national AMR stewardship rules.

In March 2023, I joined other leading academic researchers and experts from various fields in publishing a special edition of the Journal of Medicine, Law and Ethics, outlining why the Pandemic Instrument must address AMR.

The researchers of this special issue argued that the Pandemic Instrument was overly focused on viral threats and ignored AMR and bacterial threats, including the need to manage antibiotics as a common-pool resource and revitalize research and development of novel antimicrobial drugs.

Next steps

While earlier drafts of the Pandemic Instrument drew on guidance from AMR policy researchers and civil society organizations, after the first round of closed-door negotiations by Member States, all of these insertions, are now at risk for removal.

The Pandemic Instrument is the best option to mitigate AMR and safeguard lifesaving antimicrobials to treat secondary infections in pandemics. AMR exceeds the capacity of any single country or sector to solve. Global political action is needed to ensure the international community works together to collectively mitigate AMR and support the conservation, development and equitable distribution of safe and effective antimicrobials.

By missing this opportunity to address AMR and safeguard antimicrobials in the Pandemic Instrument, we severely undermine the broader goals of the instrument: to protect nations and communities from future pandemic emergencies.

It is important going forward that Member States recognize the core infrastructural role that antimicrobials play in pandemic response and strengthen, rather than weaken, measures meant to safeguard antimicrobials.

Antimicrobials are an essential resource for responding to pandemic emergencies that must be protected. If governments are serious about pandemic preparedness, they must support bold measures to conserve the effectiveness of antimicrobials within the Pandemic Instrument.

Repeated COVID-19 Vaccination Weakens Immune System: Study

Authored by Zachary Stieber via The Epoch Times (emphasis ours),

Repeated COVID-19 vaccination weakens the immune system, potentially making people susceptible to life-threatening conditions such as cancer, according to a new study.

Multiple doses of the Pfizer or Moderna COVID-19 vaccines lead to higher levels of antibodies called IgG4, which can provide a protective effect. But a growing body of evidence indicates that the “abnormally high levels” of the immunoglobulin subclass actually make the immune system more susceptible to the COVID-19 spike protein in the vaccines, researchers said in the paper.

They pointed to experiments performed on mice that found multiple boosters on top of the initial COVID-19 vaccination “significantly decreased” protection against both the Delta and Omicron virus variants and testing that found a spike in IgG4 levels after repeat Pfizer vaccination, suggesting immune exhaustion.

Studies have detected higher levels of IgG4 in people who died with COVID-19 when compared to those who recovered and linked the levels with another known determinant of COVID-19-related mortality, the researchers also noted.

A review of the literature also showed that vaccines against HIV, malaria, and pertussis also induce the production of IgG4.

“In sum, COVID-19 epidemiological studies cited in our work plus the failure of HIV, Malaria, and Pertussis vaccines constitute irrefutable evidence demonstrating that an increase in IgG4 levels impairs immune responses,” Alberto Rubio Casillas, a researcher with the biology laboratory at the University of Guadalajara in Mexico and one of the authors of the new paper, told The Epoch Times via email.

The paper was published by the journal Vaccines in May.

Pfizer and Moderna officials didn’t respond to requests for comment.

Both companies utilize messenger RNA (mRNA) technology in their vaccines.

Dr. Robert Malone, who helped invent the technology, said the paper illustrates why he’s been warning about the negative effects of repeated vaccination.

“I warned that more jabs can result in what’s called high zone tolerance, of which the switch to IgG4 is one of the mechanisms. And now we have data that clearly demonstrate that’s occurring in the case of this as well as some other vaccines,” Malone, who wasn’t involved with the study, told The Epoch Times.

So it’s basically validating that this rush to administer and re-administer without having solid data to back those decisions was highly counterproductive and appears to have resulted in a cohort of people that are actually more susceptible to the disease.”

Possible Problems

The weakened immune systems brought about by repeated vaccination could lead to serious problems, including cancer, the researchers said.

Robert F. Kennedy Jr. Banned By Major Social Media Site, Campaign Pages Blocked

Twitter owner Elon Musk invited Democrat presidential candidate Robert F. Kennedy Jr. for a discussion on his Twitter Spaces after Kennedy said his campaign was suspended by Meta-owned Instagram.

Interesting… when we use our TeamKennedy email address to set up @instagram accounts we get an automatic 180-day ban. Can anyone guess why that’s happening?” he wrote on Twitter.

An accompanying image shows that Instagram said it “suspended” his “Team Kennedy” account and that there “are 180 days remaining to disagree” with the company’s decision.

In response to his post, Musk wrote: “Would you like to do a Spaces discussion with me next week?” Kennedy agreed, saying he would do it Monday at 2 p.m. ET.

Hours later, Kennedy wrote that Instagram “still hasn’t reinstated my account, which was banned years ago with more than 900k followers.” He argued that “to silence a major political candidate is profoundly undemocratic.”

“Social media is the modern equivalent of the town square,” the candidate, who is the nephew of former President John F. Kennedy, wrote. “How can democracy function if only some candidates have access to it?”

The Epoch Times approached Instagram for comment.

It’s not the first time that either Facebook or Instagram has taken action against Kennedy. In 2021, Instagram banned him from posting claims about vaccine safety and COVID-19.

After he was banned by the platform, Kennedy said that his Instagram posts raised legitimate concerns about vaccines and were backed by research. His account was banned just days after Facebook and Instagram announced they would block the spread of what they described as misinformation about vaccines, including research saying the shots cause autism, are dangerous, or are ineffective.

“This kind of censorship is counterproductive if our objective is a safe and effective vaccine supply,” he said at the time.
