Endocrinologist Forecasts More Hormone-Related Diseases as Spike Proteins Found to Deplete Endocrine Reserves

Dr. Flavio Cadegiani, a Brazilian endocrinologist, suspects that the worst is yet to come for spike-protein-induced diseases in the endocrine system.

The endocrine system, colloquially known as the hormone system, is critical for our health. It regulates growth and development, mood, metabolism, reproduction, immunity, and functions of other organs through the secretion of hormones.

Hormones are one of the three biggest messengers in the body. Compared to the two other messengers—neurotransmitters and cytokines—hormones are slower in responding and have systemic functions across the body rather than localized actions.

While cells can usually respond to neurotransmitters in milliseconds and cytokines in minutes to hours, cells that respond to hormones can take hours or even weeks.

Since hormones can have slow and systemic actions, a dysfunctional or damaged endocrine system will generally be slow in its symptom onset and recovery.

Studies have shown that spike proteins from COVID-19 infection and the COVID-19 vaccines can damage endocrine glands, including pituitary, thyroid, and adrenal glands, as well as reproductive organs and many more.

Cadegiani raised a concern that the slower onset of endocrine pathologies may pose difficulties in diagnosis and treatment.

Depletion of Hormonal Reserves

Endocrine pathologies can take longer to become apparent because endocrine glands have “reserves,” according to Cadegiani.

“What we’re going to see in the future [for endocrine diseases] is a little bit different from the other fields, because glands have reserves and the decrease of the reserve will not be clinically seen right now, but it may be in the future,” Cadegiani said at a Front Line COVID-19 Critical Care Alliance (FLCCC) conference in Kissimmee, Florida.

Therefore, affected individuals may show no symptoms until their reserves have been depleted.

Cadegiani said most of his concerns for the future are speculative and based on his own clinical observations. But since the pandemic and the administration of COVID-19 vaccines began, there have been increasing reports that implicate endocrine pathologies.

Hormonal Axis and Systemic Dysfunction

Hormones regulate the entire body, so once the reserves are depleted and underlying endocrine pathologies are unmasked, there may be cases of systemic dysregulations.

Endocrine glands control the function of many organs across the body, and each endocrine organ is also connected through a feedback loop, also known as a hormonal axis.

At the top of this chain is the hypothalamus, which is a diamond structure in the brain and acts as a master switchboard. It sends messages to the pituitary gland, a small, oval structure tucked behind the nose.

The pituitary gland is colloquially known as the master gland; it regulates other endocrine organs together with the hypothalamus, forming hormonal axes.

The pituitary gland is part of the hypothalamic-pituitary-gonadal axis, which regulates the reproductive organs, including the ovaries and the testes. In females, it’s responsible for regulating the release of ovarian hormones as part of the menstrual cycle; in males the axis regulates spermatogenesis.

The hypothalamic-pituitary-adrenal axis is a neuroendocrine axis that mediates the adrenal glands, an organ that produces hormones that trigger the fight-or-flight response. The process is a stress response that occurs in response to harmful threats and can reduce metabolism, suppress the immune system, and activate the sympathetic nervous system.

Another major axis is the hypothalamic-pituitary-thyroid axis. This regulates the thyroid gland and the hormones it secretes. Thyroid hormones are essential for biological functions of growth, regulation of the cardiovascular system, bone replacement, liver function, and metabolism.

How Spike Proteins Target the Endocrine System

The spike protein is the most toxic part of the SARS-CoV-2 virus. Studies on people with long COVID and post-vaccine symptoms often detect spike protein presence months or even a year after exposure.

Spike proteins particularly favor tissues and organs that express ACE2 and CD147 receptors. Many endocrine glands display ACE2 receptors, including the pancreas, thyroid, testes, ovaries, adrenal gland, and pituitary gland, making the endocrine system particularly vulnerable to SARS-CoV-2.

The key driver behind spike-protein-induced disease is inflammation.

Upon entering cells, spike proteins can activate pro-inflammatory pathways by inducing DNA damage; inhibiting DNA repair; causing stress to the cell’s mitochondria, which is critical for cell energy production; and much more. All of this lead to cellular stress, injury, and possible cell death.

When many cells are affected, it can cause problems in tissues and organs, affecting individual endocrine glands and the system.

Spike proteins also inhibit autophagy, the cellular “recycling system,” thereby preventing the cells from clearing the toxic protein out, leading to prolonged damage.

Spike proteins may also contribute to autoimmunity. Since it shares many similarities with common human tissues and proteins—known as “molecular mimicry”—it has the potential to cause immune cells to mount an attack against the body’s own cells and organs, leading to endocrine damage.

Several studies have reported on endocrine pathologies following COVID-19, although data on the exact damage is still emerging.

Pituitary Gland

As the master gland of the endocrine system, the pituitary gland secretes many hormones, including ones that regulate other endocrine glands:

  • Adrenocorticotrophic hormone (ACTH) targets the adrenal glands and is responsible for producing cortisol, which stimulates the stress response.
  • Thyroid-stimulating hormone regulates the thyroid.
  • Growth hormone is responsible for growth and metabolism.
  • Melanocyte-stimulating hormone boosts the production of melanin when exposed to UV rays and increases appetite.
  • Antidiuretic hormone is responsible for retaining water and producing less urine.
  • Luteinizing hormone (LH) follicle-stimulating hormone (FSH), and prolactin are important for reproduction.
  • Oxytocin plays a role in childbirth, metabolism, and happiness.

Studies in cell culture have shown that the spike proteins are able to suppress the production of LH and FSH in pituitary cells, with unknown long-term consequences in humans.

ACTH deficiencies have been observed following mRNA vaccination in Japan, with the person affected found to have a shrunken pituitary gland.

Cadegiani said pathologies in the pituitary are difficult to diagnose; they’re often masked by other conditions, therefore there’s little literature on pituitary pathology presentation after COVID-19 vaccinations.

Adrenal Glands

There’s published literature with data that may be used as evidence to suggest spike protein injury at the adrenal glands.

The adrenal glands, located above the kidneys, produce hormones responsible for the stress response. This includes adrenaline, cortisol, and aldosterone. The release of these three hormones is critical for maintaining energy and other needs during stressful situations.

Studies on COVID-19 have shown that the adrenal glands are major sites of SARS-CoV-2 mRNA accumulation and spike protein production.

The glands are also likely to be involved in post-vaccine myocarditis events that are often seen in young males. Cadegiani said this type of myocarditis may be a sign of adrenal dysfunction.

Cadegiani authored a peer-reviewed study on post-vaccine myocarditis and concluded that catecholamines are a main trigger for these events. Catecholamines are a group of neurohormones and include dopamine, noradrenaline, and adrenaline.

While dopamine mostly acts within the nervous system, both adrenaline and noradrenaline play important roles in stress responses.

Adrenaline activates the fight-or-flight stress response and the noradrenaline supports the response by increasing heart rate, breaking down fats, and increasing blood sugar levels.

Intense and prolonged exercise triggers the fight-or-flight response, which is why catecholamines are usually elevated in athletes. Males, in particular, tend to have higher levels of catecholamine. Testosterone is also suspected to play a role in the higher incidence of myocarditis following vaccination.

Stress responses increase blood pressure, strengthen heart contraction, and when chronic, can increase the risk of cardiac events. 

Cadegiani linked catecholamines with myocarditis by analyzing the autopsy reports of two teenage boys who died three to four days after mRNA vaccination from myocarditis events. Their heart damage was different from normal myocarditis pathology, with clear similarities with stress-induced cardiomyopathy; Cadegiani observed clear characteristics of catecholamine-induced myocarditis.

He hypothesized that the vaccines triggered a hyper-catecholaminergic state by elevating levels of adrenaline, causing hyperactivation of adrenaline.

Studies on mRNA-vaccinated athletes also found that after exercise, those who were vaccinated had higher heart rates and noradrenaline levels than those who weren’t vaccinated.

Dysfunctions in the adrenal glands are likely to lead to adrenal insufficiency.

Cadegiani hypothesized adrenal insufficiency—a condition in which the adrenal glands become unable to produce enough hormones—to be a possible consequence of spike protein injury.

There’s already a report of adrenal insufficiency following infection; in the case of long COVID in which there are spike protein remnants, it’s likely that the damage will be prolonged, possibly leading to chronic damage.

In the case of vaccines, a report evaluating spike protein production after COVID-19 mRNA vaccination found that the adrenal gland was one of the highest spike protein-producing tissues, and the spike protein production in the gland increased with time.

Current research has also shown that complications from thrombocytopenia as a post-vaccine symptom have led to adrenal hemorrhage and adrenal insufficiency.

Thyroid

The thyroid is a butterfly-shaped gland located over the throat. It has a lot of functions, primarily regulating growth and metabolism.

It makes two hormones: thyroxine and triiodothyronine. Deficiencies in triiodothyronine results in hypothyroidism, characterized by a large thyroid; over-secretion of it can cause hyperthyroidism.

The thyroid also plays a role in regulating the immune system. COVID-19 infection is often a sign of underlying thyroid problems, and damage from infection can exacerbate thyroid problems, creating a negative cycle.

An autopsy study on 15 people deceased from COVID-19 found that 13 of them had viral RNA and proteins in their thyroid tissues. ACE2 receptors, previously thought to be not presented on the thyroid, were also detected, indicating a possible route for SARS-CoV-2 infection.

Although the research shows that thyroids can be implicated in infection, thyroiditis, which is inflammation of the thyroid, has currently only been reported in relation to the COVID-19 vaccine.

A study from Turkey states that the COVID-19 vaccine can induce thyroiditis. The study evaluated 15 patients who developed thyroiditis following vaccination.

Four of the patients also developed Graves’ disease, which is an autoimmune disease and a complication of hyperthyroidism. Hashimoto’s disease, another thyroid autoimmune condition, has also been reported following vaccinations.

It’s possible that spike proteins produced from vaccinations may attack the thyroid cells by binding to ACE2 receptors. However, looking at the high reports of autoimmune diseases, Cadegiani said the pathogenesis of thyroid dysfunction is likely autoimmune. The spike proteins have also demonstrated their autoimmune capacity due to high incidences of “molecular mimicry.”

Pancreas

The pancreas produces glucagon and insulin, two important hormones that regulate our blood sugar levels. Dysregulation of blood sugar levels is an indication of pancreatic dysfunction and may lead to complications, such as diabetes.

Spike proteins from both the vaccine and the virus have shown a potential to disturb glucose metabolism.

There have been reports of a sudden onset of type 1 diabetes, which is a form of autoimmune disease in which the body attacks its own pancreatic beta cells.

A study evaluating EudraVigilance safety surveillance reports also found reports of dysregulation of blood glucose with transient worsening of hyperglycemia reported after vaccinations.

Chronic hyperglycemia, meaning high blood sugar, is usually a sign of dysfunction in the pancreatic beta cells.

Therefore, Cadegiani proposed that there could be a loss or malfunction of pancreatic beta cells, as studies have shown that the spike proteins are able to directly affect and damage these beta cells, likely resulting in their death.

Reproductive Organs

The harms of COVID-19 on male reproductive organs are well established.

A study from Thailand shows that in 153 sexually active men, about 64.7 percent experienced erectile dysfunction during COVID-19 infection, with 50 percent persisting in these symptoms three months after recovery.

Erectile dysfunction has been established in research to be due to dysfunctions of the endothelial cells, and the spike proteins impair endothelial cells.

Studies linking COVID-19 and erectile dysfunction have largely blamed it on the virus’s interaction with ACE2 receptors displayed on the surface of endothelial cells. Endothelial cells are abundant in ACE2 receptors, making them one of the most targeted in COVID-19 infections.

A study evaluating adenovirus DNA vaccines shows that cells exposed to the vaccines also produced spike proteins that could interact and bind with ACE2 receptors, suggestive of equal endothelial damage.

Since the vaccine rolled out in 2021, the Centers for Disease Control and Prevention data reported 193 cases of erectile dysfunction following COVID-19 vaccination.

An Israeli study on sperm donations also noticed a reduction of 15 percent in sperm concentration and 22 percent in motile sperm count following COVID-19 mRNA vaccination.

The authors confirmed in a later response (pdf) that the people tested had no underlying health conditions, and therefore, the reduction couldn’t be because of any underlying health conditions that were existent prior to the vaccination.

Although sperm count gradually made a recovery after 145 days, sperm concentration and motility didn’t return to pre-vaccination levels, with unknown long-term effects.

Concerns of reproductive problems have also been reported in women, most particularly after vaccinations rather than after infection.

Studies show that men are generally at a higher risk of severe outcomes and deaths from COVID-19 infections; however, women seem to be at a higher risk of vaccine injury. 

VAERS data shows that more than 60 percent of adverse event reports came from women, indicating that women are more vulnerable to post-vaccine symptoms.

Dr. Paul Marik, a critical care expert, also observed that women were at a greater risk of presenting with post-vaccine symptoms in the clinic.

During the pandemic, many women reported menstrual abnormalities following vaccination. A study on Middle Eastern women found almost 70 percent of them reporting menstrual irregularities after vaccination.

A study funded by the National Institutes of Health found a “temporary increase in menstrual cycle length” linked to the COVID-19 vaccination.

A study published on the website My Cycle Story reported more than 290 women who have experienced decidual cast shedding after the COVID-19 vaccines rolled out, even though less than 40 such cases have been documented over the past 109 years. This also indicated that many of the reproductive symptoms women were suffering from may be vaccine related, rather than related to COVID-19 infections.

Cadegiani predicted greater adverse events in pregnancies for the coming future.

He cited a study that concluded “no association” between COVID-19 vaccines and fertility. However, the data show that unvaccinated women had a higher rate of pregnancy than the vaccinated, both for clinical and biochemical pregnancy.

The authors of the paper reviewed 10 studies and found that unvaccinated women have a clinical and biochemical pregnancy rate of 47 and 60 percent, respectively, while the vaccinated had a rate of 45 and 51 percent.

Cadegiani predicted more cases of endocrine pathologies as a result of spike injuries in the future.

“Endocrine diseases progress slowly and then only clinically appear in the severe states,” Cadegiani said. “So it’s not possible to tell this [anytime] beforehand.”
