SARS-CoV-2 Directly Damages Kidneys, Study Finds
https://www.iflscience.com ^ | January 6, 2022 | Maddy Chapman

It may be a respiratory disease, but COVID-19 impacts more than just the lungs. A whole host of vital organs can be affected, including the kidneys, and a recent study has finally worked out how.

SARS-CoV-2 – the virus that causes COVID-19 – can infect and directly damage the kidneys by causing scarring, according to research in the journal Cell Stem Cell. The resulting scar tissue could have long-term impacts on kidney function, the authors say.

While the ability of the virus to bind and infect kidney cells is old news, the finer details of what exactly causes damage have until now eluded scientists. This latest finding provides another “piece of the puzzle,” lead author Jitske Jansen of Radboud University Medical Center said in a statement.

In 2020, a study found that up to 50 percent of hospitalized COVID-19 patients experienced renal failure, with up to 10 percent requiring dialysis. Last year, a study of almost 90,000 COVID-19 survivors found them to be at greater risk of kidney damage than people who had never had COVID.

“Our work shows kidney scarring in COVID-19 patients, which provides an explanation why the virus might cause kidney functional decline as demonstrated in other studies,” co-author Katharina Reimer of RWTH Aachen Uniklinik said.

The team collected tissue samples from 62 COVID-19 patients admitted to the Intensive Care Unit (ICU). When compared to the control groups – ICU patients with a non-COVID-related lung infection and a group of healthy people – the tissue from COVID-19 patients showed substantially more scarring.

To identify whether the tissue damage was directly caused by the virus, as opposed to inflammation or other systemic effects, the team created “mini kidneys”. Also called “organoids”, they were cultured in the lab from stem cells, containing many different types of kidney cells, with the notable exception of immune cells. Once infected with SARS-CoV-2, the mini kidneys, like the COVID-19 patients’ tissues, became scarred. The team also found evidence of signaling molecules known to be involved in the scarring process.

“In our study, we thoroughly investigated the causal damaging effects of the Coronavirus in the kidneys. [We] show that the virus directly causes cell damage, independent of the immune system,” Jansen added.

All of this strongly suggests that the virus itself is directly responsible for the observed tissue damage.

Kidney fibrosis (scarring) can have serious long-term health implications, Reimer said, adding that further research is needed.

“Long-term follow-up studies will provide further insights into kidney-related pathologies caused by SARS-CoV-2,” she concluded.

And why haven’t we punished China for this? Don’t answer. It was rhetorical.

Are they providing cover for Remdesivir’s kidney damage?

Covid is going to have to take a number and stand in line to get a whack at my kidneys.

a wonderful patent for the CDC.

oh the royalties that they made.

from their DNA operating sys ... i mean “vaccine”, too.

gobs of money. no accountability.

death incoming and MSM is silent as professionals
die on field during performance.

as children die of diseases of 90 year olds.

silence.

no accountability.

only. MORE MANDATE.

Crux of problem, IMHO, is the immune system response to SARS-CoV-2 Spike Protein(s), whether, of the virus itself, or of the "vaccine" package result.

Need to know a person's status: What is the balance of Cytokines that help, by tilting the immune system response AWAY from an inflammatory response -vs- Cytokines that tilt the immune system response TOWARD an inflammatory response.

Vitamin D3 can help to tilt that balancing act, AWAY from an inflammatory response. In the following video, Zach Murphy explains that vitamin D processing, in addition to explaining the releases of certain cytokines:

COVID-19 and Vitamin D | Association Between Vitamin D Deficiency and COVID-19 [Sunday, 01/31/2021; video by Zach Murphy] https://www.youtube.com/watch?v=cT1CaTv5-e4


Meanwhile, given a co-morbidity label, for example: Diabetes

Focus tends to be upon that term, but, follow the cytokines:

The role of inflammatory cytokines in diabetes and its complications
https://pubmed.ncbi.nlm.nih.gov/18673007/

The Role of Inflammatory Cytokines in Diabetic Nephropathy
https://jasn.asnjournals.org/content/19/3/433

That last link: "Cytokines act as pleiotropic polypeptides regulating inflammatory and immune responses through actions on cells. They provide important signals in the pathophysiology of a range of diseases, including diabetes mellitus. Chronic low-grade inflammation and activation of the innate immune system are closely involved in the pathogenesis of diabetes and its microvascular complications."

“Are they providing cover for Remdesivir’s kidney damage?”

totally ... i know dozens of folks who had test-verified and symptomatic covid, and not a single one of them has complained to me about “long covid”, kidney damage, or anything else potentially covid-related ...

That was the point of this ex-vivo study, to determine how kidney tissue responds to the virus in the absence of an immune response. The result showed cellular damage and fibrosis was directly caused by the virus.

But your point about the immune/inflammatory response in general causing great damage and mortality is certainly well documented.

There was a recent study in Germany that followed up on (mostly mild to moderate) recovered patients 9 months after recovery, and found widespread organ damage. All of these patients were pre-vaccine, so it was definitely the virus. There are going to be long term impacts on our healthcare system from this virus.

Multi-organ assessment in mainly nonhospitalized individuals after SARS-CoV-2 infection. The Hamburg City Health Study COVID programme

One of the recommendations from the study is for people to have systematic organ screening performed 6-9 months after recovery from COVID. Heart, lungs, liver, kidneys.

Thanks for the link; I am actually trying to read the PDF file. The “phenotype” term, details, esp.

A couple of files (from my stack of stuff) that may interest you, or for your collection:

It seems to me that if it damages kidneys, what other organs are affected just as badly?

What about fertility in men and women?

What if they cause cancers in 5-10 years?.......................
