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.

Many people may dismiss swelling in an arm or leg, particularly if it's not painful. But if the swelling continues or keeps coming back, it could be a sign of lymphedema, a condition that affects the body's lymphatic system.

The lymphatic system is responsible for draining excess fluid from body tissues. If this system is damaged or is not functioning correctly, fluid will accumulate, and lead to swelling. There are different causes of lymphedema such as some infections, injuries, congenital disorders and cancer therapies. Women who have had breast or gynaecological cancers may be at special risk if they had their lymph nodes removed or if radiation had been used.

What are the WARNING SIGNS?

Sometimes, lymphedema develops gradually. Signs and symptoms include swelling of one arm or leg, heaviness or tightness in the arm or leg, trouble putting on rings or a watch, and decreased movement in the arm or leg.

At times, the skin can also be tight and turn into a hard consistency over time. In certain patients, a second infection of the skin may occur.

These symptoms should not just be attributed to "normal swelling. An early evaluation may help determine the root cause and make the condition less complicated to deal with.

What Is The Treatment For Lymphedema?

Treatment will depend on the severity of the disease and its etiology. Treatment usually involves compression garments, special physiotherapy, gentle lymphatic massage, exercises and skin care. The techniques may be used to help decrease swelling and movement.

Surgery may be necessary in some cases of more severe or chronic lymphedema. New pathways can be created to allow the excess fluid to pass, such as in a lymphovenous bypass. For some patients, a transfer of lymph nodes or liposuction may be an option.

Additionally, for patients who have an increased risk of developing lymphedema, doctors may also recommend preventive measures for individuals who must have some type of cancer surgery. This implies that measures should be taken to ensure protection of the lymphatic drainage before any appreciable swelling occurs.

When To Go To The Doctor?

If swelling isn't severe, don't wait to get help. If there is any continued or unexplained swelling, there will be a specialist available to give information about the cause of the swelling and what treatment is appropriate.

Patients are provided with a holistic treatment pathway for lymphedema with multiple specialists treating their patients who came together for the diagnosis, rehabilitation and surgical treatment of lymphedema.

Treatment of lymphedema is not all about reducing swelling. The overall aim is to maintain a person's function, ease and independence in their daily activities.

If diagnosed early, and appropriately treated and followed-up, lymphedema can be managed successfully and patients can lead their life with a growing sense of confidence and comfort.

AIIMS New Delhi has successfully performed its second dual kidney transplant using organs from a marginal donor. The procedure highlighted a strategy that could help make greater use of kidneys that may otherwise be rejected for transplantation.

The procedure was carried out on July 28 by a multidisciplinary team from the Departments of Surgical Disciplines, Nephrology, Anaesthesia, Transplant Immunology and the Organ Retrieval Banking Organisation (ORBO).

The donor was a 70-year-old woman from Command Hospital, Chandimandir, Chandigarh. Because of her advanced age and the marginal characteristics of the donated kidneys, doctors transplanted both kidneys into a single 56-year-old woman.

The organs were transported from Chandigarh to New Delhi by an Army helicopter. According to AIIMS, despite a cold ischaemia time of 12 hours, both kidneys were functioning immediately after transplantation.

The recipient showed no complications after the transplantation and was discharged after 10 days with normal kidney function.

What Is A Dual Kidney Transplant?

In a conventional kidney transplant, one donated kidney is transplanted into a recipient. Meanwhile, in a dual kidney transplant both kidneys are placed into one patient from the same deceased donor.

The approach is considered when the donor is older or the kidneys have characteristics that suggest that a single kidney may not provide sufficient function.

In simple terms, two kidneys that have lower individual functional capacity may be able to provide adequate overall kidney function when transplanted together.

Research has previously found that dual kidney transplantation can be a viable option for kidneys from older or marginal donors. Transplant teams carefully assess the donor organs and recipient before deciding whether using both kidneys together could provide adequate renal function.

A 2025 analysis comparing single and dual transplantation from marginal donors also highlighted the potential of using kidneys from a deceased donor.

Need Of The Hour

The milestone comes as India faces shortage of transplantable organs. India recorded 20,138 organ transplants in 2025, crossing the 20,000 mark for the first time, but the number of patients needing transplants remains far higher than the available organs.

Recent reports has also highlight the country's mounting transplant needs that still remain unmet despite its position as one of the world's largest transplant centres by volume.

This makes the ability to safely use organs from older or marginal donors particularly important.

“Dual kidney transplantation from carefully selected marginal donors represents an important strategy for increasing the utilization of deceased-donor organs,” AIIMS said in the press release.

AIIMS said the successful transplant demonstrates its efforts to “maximize the utilization of marginal donor organs” and help patients with end-stage kidney disease receive organs at the earliest.

Encouraging Development

The immediate functioning of both kidneys despite around 12 hours of cold storage is certainly encouraging. However, the patient’s discharge with normal kidney function represents an early outcome.

Longer follow-up will be needed to determine how well the transplanted kidneys perform over the months and years ahead.

The AIIMS team was led by Prof. Asuri Krishna, with support from the nephrology, anaesthesia, transplant immunology, ORBO and organ retrieval teams.

It is a common belief that metabolic dysfunction-associated steatotic liver disease (MASLD)—formerly known as non-alcoholic fatty liver disease (NAFLD)—is primarily associated with diet, sedentary lifestyles, and obesity. However, there are other factors as well affecting this aspect. Post-menopausal women experience a significantly higher incidence and faster progression of fatty liver disease, even when maintaining a stable body weight.

Why Menopause Increases Fatty Liver Risk

In pre-menopausal women, oestrogen plays a central role in metabolism, by promoting healthy fat accumulation in subcutaneous tissue (below the skin) rather than around internal organs, it also increases insulin sensitivity and suppresses liver inflammation.

After menopause when oestrogen levels drop, this protective function is lost, there is redistribution of fat leading to more fat accumulation around internal organs including liver thus leading to increase chances of NAFLD and also increasing insulin resistance, needless to say that with age our metabolic rate also goes down which also plays a role in this.

Early Detection Is Key

The important part lies not only in understanding above but to go further in early detection and prevention of menopause associated NAFLD. As we know that fatty liver is a silent disease and often does not causes any signs and symptoms till very advanced stage.

First and foremost is to change lifestyle with advancing age, changing both the dietary habits and physical activity. Regular screening and monitoring is warranted with blood tests, routine metabolic panels, keeping a tab on weight, sugar and cholesterol levels and a basic ultrasound of abdomen.

For someone already diagnosed with 2nd or 3rd stage fatty liver, a simple non-invasive. Fibroscan can help monitor and assess the response to treatment.

Understanding The Impact Of Menopause On Liver Health

Coming to treatment part of NAFLD in post-menopausal women, it being primary a lifestyle disease so the core of management also lies around managing lifestyle. Medicines are available for treating and controlling NAFLD in conjunction with lifestyle management.

Hormone replacement therapy (HRT), when initiated early in post-menopausal women for symptomatic relief may offer secondary benefits by maintaining metabolic health. However HRT should always be initiated after proper evaluation and expert guidance.

NAFLD is a silent epidemic and primarily a life style disease, knowing about it and knowing triggering and precipitating factors helps understanding and prevention better.

Menopause being a natural biological phenomenon in every female’s life, it becomes essential for us to know how it affects our liver health and overall health as well.
