The COVID-19 pandemic may be over, but our immune systems are still feeling the impact. After years of battling constant viral threats, from COVID-19 to seasonal flu and other infections, our body’s defense system is exhausted. Many people continue to experience lingering inflammation, frequent illnesses, and slower recovery times. This extended state of immune stress has compromised us further to chronic illness, including autoimmune diseases and even neurodegenerative diseases such as Parkinson's. So why is our immune system still in trouble? And how do we give it its power back? Understanding immune exhaustion is the beginning of rebuilding our body's natural immunity.

A weakened immune system makes people more susceptible to disease, mental illnesses, and even sleep disorders. Now, new research indicates that immune system depletion may play an important role in the onset of Parkinson's disease, a degenerative neurologic disorder that compromises movement and cognition.

Role of Inflammation in Parkinson's Disease

Dysfunctional immune response is a leading cause of long-standing inflammation within the body, that has been found to contribute towards a multitude of conditions, including cardiovascular conditions, diabetes, depression, and neurodegenerative diseases such as Alzheimer's.

As people age, their immune system naturally becomes less effective. This deterioration, referred to as immune exhaustion, may be a key contributor to the onset and progression of Parkinson’s disease. Rebecca Wallings, a Parkinson’s Foundation Launch Award grant recipient and senior postdoctoral fellow at the University of Florida, believes that an accumulation of exhausted immune cells could be driving neurodegeneration in Parkinson’s patients.

How a Tired Immune System Might Affect Parkinson's?

Parkinson's disease is most commonly linked with the degeneration and loss of dopaminergic neurons—motor nerve cells that produce dopamine, an essential neurotransmitter for movement. While researchers have long suspected inflammation is involved in this neurodegeneration, the mechanisms are not yet well understood.

Wallings' study is on immune cell exhaustion, a process by which aging immune cells fail to control immune responses effectively. Her research indicates that instead of dampening inflammation in Parkinson's patients, attempts should be made to rejuvenate the immune system to regain its functionality.

Energy Deficiency in Immune Cells

One of the major findings of Wallings' work is the function of mitochondrial impairment in immune cell exhaustion. Mitochondria are commonly called the powerhouses of cells, as they are vital for generating energy. As mitochondria age and become inefficient, immune cells fail to function well, potentially accelerating neurodegeneration in Parkinson's disease.

Wallings has found that mutations in the LRRK2 gene, a recognized genetic risk factor for Parkinson's disease, are linked with defective mitochondrial function and immune cell exhaustion. Her current work includes testing various therapeutic approaches to restore mitochondrial function in immune cells with the potential to enhance the immune system and potentially prevent or treat Parkinson's disease.

Will Rejuvenating the Immune System Help in Treatment?

For decades, the standard practice in treating Parkinson's has been to suppress brain inflammation. Yet Wallings' work indicates that instead of slowing down immune responses, restoring the immune system could be a more successful strategy. By addressing mitochondrial impairment and immune resilience, researchers can potentially reverse or slow down Parkinson's disease.

Wallings is now looking into how to rejuvenate immune cells by fixing mitochondria. She studies immune cells from patients with Parkinson's as well as from healthy subjects and performs experiments on animal models to determine if rejuvenation of the immune system could result in improved disease outcomes.

Lifestyle Factors That May Affect Parkinson's Risk

While there is no cure for Parkinson's disease, some lifestyle adjustments may decrease the chances of developing the illness. Since neurodegenerative diseases are associated with chronic inflammation and immune dysfunction, developing habits that enhance immune function might prove helpful.

Diet: There is evidence to suggest that eating in accordance with the Mediterranean or MIND diets, both high in antioxidants, healthy fats, and anti-inflammatory foods, can encourage brain wellness and reduce Parkinson's risk.

Avoiding Dangerous Substances: Restricting alcohol and nicotine use can maintain a robust immune system and suppress inflammation.

Reducing Stress: Chronic stress weakens immune function, so methods such as meditation, exercise, and sufficient sleep can lead to improved overall well-being.

Sepsis that happened by a lick from a pet dog led to a woman losing all four of her limbs. Health and Me had previously reported that a Birmingham based woman, 56-year-old pharmacy worker Manjit Sangha caught sepsis from the lick of her pet dog. She spent her night in coma in the hospital and had to lose all her limbs. This happened because bacteria from dog's lick entered her body through a cut or a scratch. This led to sepsis, where the immune system's reaction to infection damaged the body's own tissues and organs.

This has brought a lot of attention on what sepsis is and what are the symptoms one must be aware of. As per the Sepsis Alliance, one must know about TIME to be aware of sepsis.

Unique Symptoms of Sepsis

TIME stands for temperature, infection, mental decline and extremely ill. If you notice these symptoms, rush to the hospital.

• T for Temperature: If you notice your body temperature rising or falling
• I for Infection: If you see signs or symptoms of any infection
• M for Mental Decline: If you feel confused, sleepy and difficult in rising
• E for Extremely Ill: If you feel severe pain, discomfort, shortness of breath

Unique Symptoms Of Sepsis: What To Know About Temperature

Your body temperature normally stays steady at about 98.6°F (37°C), with small changes based on activity, surroundings, and time of day. A reading of 100°F (37.7°C) or higher is considered a fever. During infection, the body often heats up to help fight germs. However, some people experience an unusual drop in temperature instead. Because of this, both a spike and a fall in temperature can be warning signs of sepsis.

Unique Symptoms of Sepsis: How To Know If You Have An Infection?

When an infection stays in one area, its symptoms usually match the site involved. A urinary tract infection may cause burning while urinating or frequent urges, pneumonia can bring cough and chest pain, and an infected cut may show redness or pus.

If the infection spreads through the body, broader symptoms like fever, tiredness, and body aches can appear. In some cases, an infection may not cause obvious symptoms at all. This is especially important to remember after surgery, medical procedures, skin injuries, or close contact with someone who is sick.

Sepsis can also alter how the brain functions. Some people, particularly older adults, may not develop the usual infection symptoms. Instead, they might suddenly become confused or show a sharp worsening of existing dementia. Marked drowsiness or unusual sleepiness is another common sign.

Unique Symptoms of Sepsis: Signs That You Are Extremely Ill

Many sepsis survivors recall feeling sicker than ever before. They describe overwhelming symptoms such as the most severe sore throat or abdominal pain they had experienced, along with a frightening sense that they might not survive.

Mounjaro, a popular weight loss drug that helped many lose weight, however, in this one case, a woman, who was on the same drug noticed something different. While she lost weight, she noticed that her breasts continued to grow. The 30-year-old Tianna Moon of East Anglia, a region in eastern England first realized something was not normal with her chest in 2024. This was when she started to use Mounjaro.

She was losing weight, but her breasts continued to grow. This is when Moon's doctor diagnosed her with a rare disease call gigantomastia, which causes breast tissue to grow rapidly and in excess.

Woman Lost Weight On Mounjaro But Her Breasts Didn't Stop Growing: What Happened To Her?

Moon said that the doctors had thought that she had macromastia, a less severe, however, a similar condition. "But when I broke down medical history, the weight loss on Mounjaro and the increased growth and side effects, he was point-blank like, 'This is gigantomastia'," she said.

Moon also told that her breasts currently weight 39 lbs, which is approximately 20 per cent of her overall body weight.

Moon also said that while her large breasts are "normal" at this point in her life, she said the rare condition still comes with challenges.

"The side effects are having numb arms quite a lot and having quite severe indentations on my shoulders. I have some light scarring under my breasts where bras have rubbed and ripped the skin open."

She also said that laying on her back is something she cannot do for a long time, as it restricts the amount of airflow she can get in. She also said that when she goes out she tries to make her breasts look smaller than they are and strap them up. "I [still] get stares and double takes."

Woman Lost Weight On Mounjaro But Her Breasts Didn't Stop Growing: What Is Gigantomastia?

As per Cleveland Clinic, it is a rare condition where your breasts become excessively large. It can also cause pain, infection, discomfort and issues with body image. It is also known as breast hypertrophy where one experiences rapid and disproportionate breast growth. The speed with which the breasts grow could vary depending on the person. It could take a few weeks to over several years. The tissue is almost never benign.

Gigantomastia is characterized by:

• Breasts that have an excess of at least 5 pounds of breast tissue.
• Extra breast tissue that equals more than 3% of your total body weight.

There are different types of gigastomastia:

• Juvenile gigantomastia: This type happens during puberty.
• Gestational gigantomastia: This is when gigantomastia occurs during pregnancy.
• Drug-induced gigantomastia (or medication-induced): This happens after taking certain drugs.
• Idiopathic gigantomastia: This is when the cause of gigantomastia is unknown or can't be determined. Idiopathic gigantomastia is the most common type.

Moon is now considering a breast reduction surgery. She has for now set up an account on OnlyFans. “I might as well try and reap the benefits of my medical condition rather than the negatives," she said.

The recent launch of the indigenous Td vaccine in India by Union Health Minister JP Nadda will boost immunity and reduce the risk of tetanus and diphtheria in children and adults, said health experts.

Union Health Minister JP Nadda formally launched the indigenously manufactured Td vaccine in Himachal Pradesh last week.

With the launch, the Tetanus Toxoid (TT) vaccine has been replaced with the Tetanus and adult diphtheria (Td) vaccine in India’s immunization program for all age groups, including pregnant women.

The move comes amid increasing numbers of cases of diphtheria amongst older age groups. Tetanus and diphtheria can lead to hospitalizations or even cause death. The Td vaccine will help to decrease diphtheria outbreaks.

“In keeping with global practice, India has shifted from TT, which covers for tetanus, to Td, which covers for both tetanus and diphtheria. This vaccine is indigenously manufactured and is expected to significantly reduce the risk of both these diseases in older children as well as adults,” Dr. Rajeev Jayadevan, Ex-President of IMA Cochin and Convener of the Research Cell, Kerala, told HealthandMe.

What Is The Td Vaccine?

The Td vaccine, indigenously manufactured at the Central Research Institute (CRI), Kasauli in Himachal Pradesh, is a combination of tetanus and diphtheria with a lower concentration of diphtheria antigen (d), and is recommended for older children and adults.

The use of Td, instead of TT, is recommended during pregnancy to protect against maternal and neonatal tetanus and diphtheria during prenatal care.

Vaccination during pregnancy also serves to boost immunity and increase the duration of protection in pregnant women who have not received the full set of recommended booster doses.

The Td is a safe vaccine, and 133 countries are currently using it.

The Health Ministry, in a statement, said that the Central Research Institute will supply 55 lakh doses to the UIP by April 2026, with production expected to scale up progressively in subsequent years to further strengthen the Universal Immunization Program in India.

“India’s indigenous Td vaccine rollout marks a significant milestone in strengthening the nation’s immunization program by enhancing self-reliance, affordability, and supply stability,” Dr. Neha Rastogi, Senior Consultant - Infectious Diseases, Fortis Gurugram, told HealthandMe.

“Locally produced vaccines reduce dependency on imports, ensuring uninterrupted protection for adolescents and adults against tetanus and diphtheria. This initiative supports wider coverage, faster distribution to remote regions, and improved public health preparedness,” she added.

Tetanus And Diphtheria: Disease burden In India

As per the National Health Profile 2022, India has reported 1,586 cases and 22 deaths due to diphtheria in 2020, and 3,677 cases and 47 deaths in 2021.

Around 10 Indian states report the majority (84 per cent) of the cases.

As of 21 June 2024, Orissa has also reported six deaths and 21 suspected diphtheria cases. There has been more than 90 percent coverage of diphtheria vaccination in birth cohorts since 2014, but gaps in booster dose coverage are widely prevalent.

Plugging of gaps in the routine immunization, coupled with inclusion of booster doses in the national data on diphtheria vaccination, is the need of the hour.

“Diphtheria is one of the most dangerous infectious diseases known to man; it spreads easily through the respiratory route. It can cause death due to the bacterial toxin affecting the heart (Myocarditis). It is vaccine-preventable, but the immunity fades over time,” Dr. Jayadevan said.

Therefore, the Td booster shots at ages 10 and 16 are essential to maintain protection. Similarly, pregnant women should receive two doses to protect both mother and child.

Given the recent outbreaks of diphtheria in India and elsewhere, this transition is a public health priority, the expert said.
