bookmark_borderLong-COVID’s Similarity to HIV

Posted on by admin

Persistent viruses are not cleared but remain in specific cells of infected individuals. Persistent infections may involve stages of both silent and productive infection without rapidly killing the host. Diseases caused by persistent virus infections include acquired immune deficiency syndrome (AIDS), AIDS-related complexes, chronic hepatitis, subacute sclerosing panencephalitis (chronic measles encephalitis), chronic papovavirus encephalitis (progressive multifocal leukoencephalopathy), spongioform encephalopathies (caused by prions), several herpesvirus-induced diseases, and COVID-19. The mechanisms by which persistent infections are maintained involve both modulation of virus and cellular gene expression and modification of the host immune response.

COVID has been found to persist for months in individuals even if their case was mild. The virus continues to infect multiple organs including the brain. The U.S. National Institutes of Health said they found the pathogen is capable of replicating in human cells beyond the respiratory tract and can infect all organs.

There are many questions about Long-COVID (also known as Long Haulers Syndrome.)

Long-COVID is the condition most people develop after recovering from the SARS-CoV-2 virus. Between 40 and 70% of recovered COVID cases report lingering symptoms, but it is quite likely 99.9% of recovered individuals have silent conditions. COVID-19 makes a multitude of changes to the human genome. Some of the changes result in noticeable symptoms, such as, brain fog, fatigue, soreness, night sweats, diarrhea, and loss of taste. There are also many changes to the genome that may go unnoticed, such as, an increase risk of cancer, rogue antibodies, and blood clotting.

The epigenetic changes that cause Long-COVID are very similar to having HIV.

The Journal Nature reports in the article HIV infection alters the human epigenetic landscape, “Early in 2010, a study on the DNA methylation status of B lymphoma confirmed that HIV infections may induce novel epigenetic changes, including DNA methylation status alteration of specific functional sites.”

“Immune dysregulation during HIV infection can increase anemia risk through red blood cell destruction (hemolysis) or ineffective red blood cell production,” according to BMC Infectious Diseases. This is similar to symptoms in some Long-COVID patients. Long-COVID is known to result in a variety of blood issues.

“HIV enters its genetic information into helper T cells to make copies of itself. When this happens, the helper T cells die. This severely disrupts the immune response. Low levels of helper T cells mean killer T cells and other white blood cells do not receive as much information about pathogens in the body,” as reported in Medical News Today. Long-COVID is also suspected of interfering with T cells and the immune system. Long-COVID causes an upregulation in IDO. Indoleamine 2,3-dioxygenase (IDO) is an immune checkpoint molecule in the sense that it is an immunomodulatory enzyme produced by alternatively activated macrophages and other immunoregulatory cells. IDO is known to suppress T and NK cells, generate Tregs and myeloid-derived suppressor cells, and also supports angiogenesis.

In December 2021, typical seasonal viruses’ severity was up suggesting recovery from COVID results in a compromised immune system. T cells may lose effectiveness against any pathogen. It is estimated half of the U.S. population has had a COVID infection. Hospitals are seeing a sharp rise in Flu, RSV, and other viral infections. It is also likely infants and younger children are contracting the viruses due to their parents compromised immune systems.

The epigenetic changes caused by both Long-COVID and HIV compromise the immune system.

The study SARS-CoV-2 infection and persistence throughout the human body and brain examines COVID living in people for many months after their initial illness.

“This is remarkably important work,” said Ziyad Al-Aly, director of the clinical epidemiology center at the Veterans Affairs St. Louis Health Care System in Missouri, who has led separate studies into the long-term effects of COVID-19. “For a long time now, we have been scratching our heads and asking why long COVID seems to affect so many organ systems. This paper sheds some light, and may help explain why long COVID can occur even in people who had mild or asymptomatic acute disease.”

WHAT WE KNOW ABOUT Long-COVID
* Epigenetic Modifications (Changes to DNA)
* Change in Cell Fate
* Tryptophan Deficiency
* Dysfunctional Kynurenine Pathway
* Neurological Damage
* Down Regulating NAD+
* Up Regulating IDO
* Rogue Antibodies
* Change in Pancreas Cell Function (Down regulation of Insulin)
* Increased Risk of Cancer
* Blood Clotting — This unusual clotting may cause different complications, including organ damage, heart attack and stroke.

COVID and Cats:
A scientist friend called me last night… wanted to make sure I stocked up on enough masks and supplies for the next round featuring Omicron. We got to talking about severity of variants and what the most likely scenarios are:
1) the virus stays for a prolonged period in an unvaccinated immune compromised individual
2) the virus jumps back into animals and mutates before jumping back into humans
His theory is cats are a reservoir for SARS-CoV-2. And, that cats are spreading COVID to mice and deer… and back into humans. Some studies have shown 20-50% of cats that belong to owners that have had COVID develop COVID. Studies have also found that cats can transmit the virus to other cats. The risk is especially great for pets that share a bed with their owner.

Some other things we discussed:
* the pandemic is going to go on for years
* there is no natural immunity to Omicron
* there may be no immunity from vaccines to Omicron
* the severity of Omicron will take some time to determine… since we don’t know how much immunity / less severe symptoms vaccines may offer, yet. There is some possibility that prior infection may offer some protection to severity, but that is unlikely.
* N95 masks and social distancing offer the best protection to all variants of COVID
* we do not fully understand the long term effects of COVID. Until we do, avoid contracting the virus… and probably after we do understand, it will become clear the reduction in life expectancy and quality of life

To date, there is zero (0) evidence that contracting the original strain of COVID gives you any immunity to re-infection — natural immunity. On the other hand, there are a multitude of examples of re-infection.

Natural immunity to the original strain lasts on average from 60 days to 6 months; however, there does not appear to be any natural immunity to the variants.

In India’s recent wave, 1 in 4 Delta cases were re-infections. “Antibodies against Sars-CoV-2 — the virus that causes Covid-19 — were found in about 27% of the 91 participants at a time when the second wave was raging in the country, researchers at the Institute of Genomics and Integrative Biology, National Centre for Disease Control and the Cambridge University, said.” — Hindustan Times

“During the Novavax vaccine trials in South Africa, the study found an overall primary efficacy of 49.4% in 4,400 participants, meaning about half of the patients vaccinated and later infected did not experience symptoms. Genomic analyses revealed that about a third of the 4,400 were previously positive for infection, meaning the South African variant was then and is now capable of reinfection, evading neutralizing antibodies in a similar capacity to the Brazilian variant.”

“The study also showed that prior infection with an earlier version of the virus did not reduce the risk of COVID-19 caused by the South African variant among people who got placebo shots.” — Reuters

Another variant (C.1.2) related to the original South Africa variant (C.1) was discovered in South Africa, China, the Democratic Republic of the Congo, Mauritius, England, New Zealand, Portugal and Switzerland. A study by the National Institute for Communicable Diseases (NICD) and the KwaZulu-Natal Research Innovation and Sequencing Platform (KRISP) in South Africa found the variant could be more transmissible and evade protection provided by vaccines and prior infection.

“Among Kentucky residents infected with SARS-CoV-2 in 2020, vaccination status of those reinfected during May–June 2021 was compared with that of residents who were not reinfected. In this case-control study, being unvaccinated was associated with 2.34 times the odds of reinfection compared with being fully vaccinated.” — CDC

“Our case series shows that reinfection with different strains is possible, and some cases may experience more severe infections with the second episode. The findings also suggest that COVID-19 may continue to circulate even after achieving herd immunity through natural infection or vaccination, suggesting the need for longer-term transmission mitigation efforts.” — Journal of Investigative Medicine

Vaccines do not appear to be much more effective against the Delta variant than natural immunity through infection. The increase of breakthrough cases has been increasing in lock-step with the increase spread of the Delta variant. “Fewer than 10% of new coronavirus infections occurred in fully vaccinated people in the weeks before June, but the rate increased this summer. In the first four weeks of August, roughly 30% of infections were in fully vaccinated individuals.” — The Star Tribune

A study by the CDC found vaccine efficacy dropped from roughly 90% to 66% as the Delta variant emerged. “This report updates vaccine effectiveness (VE) estimates including all COVID-19 vaccines available through August 14, 2021, and examines whether VE differs for adults with increasing time since completion of all recommended vaccine doses.” — CDC

Another CDC study that compared natural immunity to vaccination has found — “Among COVID-19–like illness hospitalizations among adults aged ≥18 years whose previous infection or vaccination occurred 90–179 days earlier, the adjusted odds of laboratory-confirmed COVID-19 among unvaccinated adults with previous SARS-CoV-2 infection were 5.49-fold higher than the odds among fully vaccinated recipients of an mRNA COVID-19 vaccine who had no previous documented infection.”

CONCLUSION PART I
There is a need for longer-term transmission mitigation efforts. Because reinfection is likely, vaccines efficacy is not high enough, and new variants are emerging, herd immunity is not achievable. Humans can not learn to live with the virus. Mitigation efforts must be made to stop community spread.

CONCLUSION PART II
COVID causes an immune dysfunction. When a person become infected, the SARS-CoV-2 virus alters your genes in order to infect you. “We identified EP300, MOV10, RELA, and TRIM25 as top candidates, and more than 60 additional proteins involved in the epigenetic response during viral infection that has therapeutic potential.” — Nature

When a person recovers from the virus, they are left with multiple gene alterations to there immune system. It is impossible for natural immunity to be feasible in an individual with an immune system that is compromised by a COVID-19 infection.

COVID survivors are left with a severe NAD+ deficiency, and an upregulation of IDO (which suppresses your T and NK cells.) Short term this makes your immune system dysfunctional. This means your antibodies can’t function properly and have little to no memory. Long term it makes you more likely to have heart, blood, respiratory, and neurological disorders. You are at high risk of developing dementia. In addition, you have reduced P53 genes (tumor suppression genes) putting you at higher risk of cancer. — The Membrane Domain

I strongly advise against contracting COVID.

OMICRON UPDATE
December 4, 2021

A study out of South Africa, “Increased risk of SARS-CoV-2 reinfection associated with emergence of the Omicron variant in South Africa,” found that individuals who recently recovered from the Delta variant were afforded little to no protection from the Omicron variant. “Population-level evidence suggests that the Omicron variant is associated with substantial ability to evade immunity from prior infection. This finding has important implications for public health planning, particularly in countries like South Africa with high rates of immunity from prior infection.”

As stated above, everybody is advised to:
* speak to your doctor
* get vaccinated
* wear an N95 mask
* stay socially distanced

UPDATE June 2022: No Immune Boost From Omicron
“If you were infected during the first wave, then you can’t boost your immune response if you have an Omicron infection,” said Prof Rosemary Boyton, of Imperial College London, a co-author of the study. “When Omicron started flying around the country, people kept saying that’s OK, that will improve people’s immunity,” said Boyton. “What we’re saying is it’s not a good booster of immunity.”

“It’s actually worse than that, because the adaptations that the spike [protein] has now are actually inducing a kind of regulation or shutdown of immune response,” Prof Danny Altmann, another author of the study, adding that while the study looked at responses to the BA.1, similar findings were likely for other subvariants of Omicron.
