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 couples are battling infertility and are keen on opting for ARTs to conceive and fulfill the dream of parenthood. However, the country continues reeling under severe heatwave conditions. Currently, a large number of couples who are planning fertility treatments are becoming stressed regarding how heatwaves can impact IVF procedures and even the success rates. Patients frequently ask fertility consultants whether extreme outdoor heat can affect the IVF laboratory environment, embryos, sperm samples, or even egg quality. However, there is no need to panic, as labs are designed to function even under highly controlled conditions throughout the year, and it is possible for couples to conceive successfully.

In an interaction with Health and Me, Dr. Aswati Nair, Fertility Specialist, Nova IVF Fertility, Rajouri Garden, Delhi, spoke about how extreme temperatures can affect the IVF process and what the consequent impact is on the outcome.

Does a heatwave affect the IVF lab?

Usually, all the IVF labs have Air Handling Units (AHUs), which maintain the internal condition of the lab throughout the year at the same condition and temperature, and all the parameters are maintained throughout the year with the help of this equipment and gadgets. So, the internal environment of the lab does not get affected by an external heatwave. Understand that the temperature-sensitive procedures that are carried out inside the IVF lab, such as handling eggs, sperm, and embryos, are performed in a controlled setting and are monitored constantly. Hence, external heatwaves do not directly impact the IVF lab environment or the development of embryos. But only from the patient's perspective; they need to be hydrated and careful when there is scorching heat outside.

Too much heat can lead to dehydration, weakness, fatigue, dizziness, and stress, which can impact the patient’s health during fertility treatment. Women undergoing IVF cycles are put on hormonal medications, and staying hydrated is necessary for everyone. It is the need of the hour for the patients to take charge of their well-being right away!

Precautions to take

The precautions that patients can take are to stay well-hydrated and adhere to a balanced diet with lots of fruits and seasonal fruits like watermelon and muskmelon, which can improve hydration. They can have coconut and lemon water and avoid beverages, carbonated drinks, caffeine, and alcohol. They can follow these crucial tips to stay healthy during the heatwave. Patients should be sure to follow the guidelines given by the fertility consultant.

Even if the heatwaves can lead to discomfort, it doesn’t affect the functioning of modern IVF laboratories. By paying attention to various factors such as hydration, nutrition, and self-care, patients can safely continue their fertility journey even if there is extreme heat outside.

Mrs. Radha Sharma, 78, was brought to the hospital with sudden confusion, irritability, and restlessness. She had no fever, no pain, and no typical urinary complaints. Her family worried it could be dementia or a brain-related issue. However, a simple urine test revealed the real cause— a urinary tract infection (UTI). With timely treatment, fluids, and care, she recovered within a few days. This is a common but often overlooked reality—UTIs in older adults don’t always look like UTIs.

In another case, 72-year-old Mr. Pankaj Verma had repeated UTIs over a year. Each time, antibiotics provided temporary relief, but the infection kept returning. On further testing, doctors found an enlarged prostate that was preventing his bladder from emptying fully. Once this was treated, his infections reduced significantly.

These examples show an important pattern: in the elderly, UTIs are often missed, misunderstood, or keep recurring because the root cause is not addressed.

Why Are UTIs So Common In Older Adults?

As we age, the body goes through changes that make infections like UTIs more likely. In women, menopause leads to a drop in estrogen levels. This weakens the natural lining of the urinary tract, making it easier for bacteria to grow. Women also have a shorter urinary passage, so that bacteria can reach the bladder more easily.

In men, an enlarged prostate is a common issue. It can block the flow of urine, causing some urine to remain in the bladder. This leftover urine becomes a breeding ground for bacteria. Other common reasons include weaker immunity, conditions like diabetes, urinary incontinence, use of catheters, reduced movement, and dependence on caregivers for hygiene.

Symptoms Are Not Always clear

Unlike younger people, elderly individuals may not complain of burning urine or urgency. Instead, the signs can be subtle and confusing, such as:

• Sudden confusion or unusual behavior
• Increased falls
• Weakness or tiredness
• Loss of appetite

These symptoms are often mistaken for ageing or dementia, which can delay treatment.

Men vs Women: What’s the Difference?

UTIs are more common in older women due to hormonal changes and bladder control issues. Many women also experience repeat infections. In men, UTIs are less common but usually more serious. They are often linked to problems like prostate enlargement or urinary blockage, which need proper evaluation. Chronic illnesses play a big role. Diabetes, for example, increases the risk because excess sugar in urine helps bacteria grow. Poor sugar control also weakens the body’s ability to fight infections.

Conditions that affect bladder control, such as stroke or Parkinson’s disease, can also lead to incomplete emptying of the bladder, increasing infection risk.

Diagnosis Needs Careful Attention

Not every bacterium found in urine needs treatment. Many older adults have bacteria in their urine without symptoms—a condition called asymptomatic bacteriuria. Treating this unnecessarily can lead to antibiotic resistance. Doctors usually rely on urine tests, cultures, symptoms, and medical history before deciding on treatment.

Treatment: More Than Just Antibiotics

While antibiotics are important, they are only one part of the solution. Repeated courses without finding the cause often lead to recurring infections.

Treatment should also focus on:

• Drinking enough fluids
• Managing diabetes or other health conditions
• Treating prostate problems in men
• Avoiding unnecessary catheter use
• Reviewing medications that may affect bladder function

Early treatment is crucial. Ignoring symptoms can allow the infection to spread to the kidneys, which can be serious. Recurrent UTIs are common in the elderly. This can happen due to:

• Incomplete treatment
• Underlying problems like prostate enlargement
• Ongoing issues, such as incontinence or catheter use
• Antibiotic resistance

Prevention: Simple But Effective Steps

Preventing UTIs doesn’t always require complex measures. Small daily habits can make a big difference:

• Encourage regular water intake
• Avoid holding urine for long periods
• Maintain proper personal hygiene
• Manage conditions like diabetes well
• Limit catheter use
• Consider probiotics or cranberry products (after medical advice).

Caregivers play a key role in ensuring these habits are followed, especially for elderly individuals who need assistance. Immediate medical attention is needed if there is:

• Fever or chills
• Sudden confusion
• Blood in urine
• Lower back pain

UTIs in the elderly are common but often not straightforward. They may present differently, recur frequently, and require more than just antibiotics. The key is early recognition, identifying the underlying cause, and taking simple preventive steps. With the right care, recurrent UTIs can be reduced—helping older adults live healthier, more comfortable lives.

Systematic Lupus Erythematosus (SLE), also known as Lupus, is a multisystem autoimmune disease in which one's immune system attacks the body. It is most common in women of reproductive age; however, in rare cases, it can present in men and patients of any age.

Lupus Symptoms: More Than Just Joint Pain

Symptoms for SLE can range from unexplained fever for days to months, to oral ulcers, malar rash, photosensitivity (after exposure to sun), hair loss, headache, stroke, seizure, abnormal behavior (psychiatry lupus). A large group of patients experiences joint swelling, pain, and fatigue. If the kidneys are affected in Lupus patients, they can pass blood with their urine.

Their urine output also decreases; their legs swell, and there is swelling around the eyes. Involvement of the heart, brain, and pancreas is also not uncommon. Lupus is one of the causes of multiple unexplained pregnancy losses, especially in the second trimester, but with proper treatment and observation, many patients do well and have an uneventful pregnancy and childbirth.

Common Myths About Lupus

Some very prominent myths about SLE need to be debunked. Many think SLE is contagious and that only women can get it, when in reality, neither is true. Being an autoimmune disease means it cannot spread by contact, and it impacts both men and women, although the incidence rate of SLE is higher for women. Many also believe in the common misconception that it affects only joints, when in reality it is a multisystem disease that can affect the kidneys, heart, brain, skin, and lungs.

There is a common myth that pregnancy is impossible or unsafe for women with Lupus; however, many women with Lupus can conceive and experience safe and healthy full-term pregnancies under the right medical guidance. Kidney biopsy, which is a required test for treating Lupus, is often deemed unsafe, but it is a safe test and is required to decide the stage of the disease and treatment.

Lupus: Warning Signs

Some symptoms that can be a cause of alarm in SLE are rapid rising serum creatinine, new onset seizure or psychosis, sudden onset shortness of breath associated with chest pain, blood in cough with low oxygen saturation, acute confusional state with fever, vision changes, severe abdominal pain, unexplained severe anemia, severe thrombocytopenia (platelet count < 20,000).

Managing Lupus

For accurate diagnosis and treatment, one needs a rheumatologist's consultation. Rheumatologists will decide the plan of treatment to manage symptoms, reduce inflammation, prevent flares of the disease, and minimize organ damage. Lifestyle measures like avoiding Sun exposure, quitting smoking, lowering stress, and engaging in some low-impact physical activities help patients to minimize the disease burden.

There is very little awareness about Lupus in society, and due to varied presentations and symptoms, patients often consult with multiple doctors of different specialties before consulting with rheumatologists. We need to push for more awareness in society about less talked-about ailments like Lupus, which needs efficient intervention and management, as it is a lifelong condition. Talking about it also helps reduce stigma and bust myths around it. Late diagnosis and delay in treatment can cause significant morbidity, disease progression, and mortality. With early diagnosis and optimal treatment.

Holistic care is possible, which goes a long way in helping individuals manage autoimmune conditions like Lupus
