Plasma Treatment For COVID-19?

TREATING COVID WITH BLOOD

We have previously covered proposed treatments for COVID-19, in particular hydroxychloroquine, and explained why we shouldn’t look for a magic cure for this disease. Viruses are difficult to treat, and ultimately supportive treatment appears to be best we can achieve. But an editorial published in BioMedicine Central appears to show a novel treatment for the most ill patients, one that may have flown under most people’s radar.

“A novel treatment approach to the novel coronavirus: an argument for the use of therapeutic plasma exchange for fulminant COVID-19”

An interesting title. Lets dissect it.

SUMMARY

- Blood is made up of many different components

- The immune system recognises the virus and produces antibodies against it to neutralise it

- These antibodies float in the blood plasma, a watery solution

- The plasma can be extracted from donated blood, and given to patients suffering from COVID-19

- So far evidence suggests it can help treat the most seriously affected patients.

WHAT IS IN OUR BLOOD

To understand this we must first understand what our blood is made of. Most people know that blood functions to transport oxygen from our lungs. But this is an oversimplification. Blood has many different functions:

- Transport: along with oxygen it transports sugars, fats, protein subunits throughout the body. This is done with the watery PLASMA of the blood.

- Clot: cells and protein structures act to plug any holes that form from cuts and damage. This is done by the PLATELETS in the blood

- Immunity: Immune cells respond to bacteria, viruses, parasites in the blood and body. They target these pathogens, identify and tag them with antibodies, and ultimately destroy them. This is done by the WHITE BLOOD CELLS.

And many more functions that we won’t bore you with.

IMMUNITY

It is this last point that is of interest to us. Our immune system consists of white blood cells that can recognise invading organisms in the blood, around cells and even invaders hiding within our own cells. All cells have protein markers on their surface, no matter if its human cells, bacterial, viral, fungal etc. These markers can be highlighted and targeted by specialised white blood cells, who in turn produce antibodies against these markers. Think of antibodies as handcuffs with flares attached: once attached other white blood cells use this information to find and destroy the invaders.

What is amazing about antibodies is how complex they are. The proteins in our body are incredibly complex. They are long chains that fold into unique shapes depending on hundreds of different types of chemical interactions. These are so complex that supercomputers can take literal years to figure out the shape of a single protein and how it folds depending on the subunits in its chain. This means that our immune system has to recognise these markers and figure out a complementary tag out of hundreds of billions of potential sequences. Antibodies have to be specific to their tag. If an antibody is produced that can target more than one tag, it can cause problems. If it targets a bacterial tag, but accidentally highlights the person’s cells as well, the immune system will start targeting and destroying the person’s organs. These auto-immune disorders can be devastating.

But when they work, antibodies are miraculous. They persist in the blood after an infection, and if a second infection occurs, memory cells in the blood can rapidly produce these antibodies before the infection can even produce symptoms. This is known as immunity, and is why we usually don’t get the same illness twice. Antibody based treatment is see as the future of medical therapy, and is something we will cover in future blogs.

PLASMA EXCHANGE

From population testing we can see that the majority of patients with COVID-19 recover, experiencing either mild symptoms, moderate symptoms requiring some form of treatment and hospitalisation, or no symptoms whatsoever. In these patients their immune system will have successfully recognised the virus and produced antibodies against it to neutralise the virus. It is the patients with severe symptoms, those in which the virus is running rampant in the body, that the production of antibodies happens too late.

Plasma exchange involves obtaining blood from patients who have beaten the virus, spinning the blood to separate out the red cells, white cells, platelets and watery plasma. The plasma contains all the glucose, small proteins and importantly for us, the antibodies. This plasma can be transfused into patients with COVID-19 that cannot cope, in order to help their immune system. These transfused antibodies will neutralise some of the viruses in the patient, reducing the viral load, amount of replication and cell destruction that causes such devastating symptoms in COVID-19.

The published editorial showed that in the most critical pneumonia patients, requiring mechanical ventilators and drugs to support the heart, mortality in plasma exchange patients resulted in a 47.8% mortality instead of 81.3%. Of course it is a single study with a limited number of patients, but the results are encouraging. It is further helped by the fact plasma exchange is a well established therapy, with established protocols known to intensivists and haematologists.

THE FUTURE

We may see the use of Plasma exchange for critically ill patients increase as the pandemic continues. It is not a treatment option available for everyone, as it requires intravenous access and careful monitoring in a controlled setting. But it also needs donation from people who have recovered from COVID and have suitable antibodies. So whilst it might not be a magic pill that everyone expects to cure COVID, it might be the difference between life and death for those that need it most.

Virtual Cooking Class with a Dietitian: Why It’s a Powerful Corporate Wellness Benefit

Corporate wellness programs in India are undergoing a meaningful transformation. What once revolved primarily around annual health checkups and gym memberships is now shifting toward sustainable lifestyle-based interventions. Among these, the virtual cooking class with a dietitian has emerged as one of the most practical and high-impact wellness initiatives for modern workplaces.

Poor dietary habits are a leading contributor to lifestyle-related conditions such as diabetes, obesity, hypertension, and heart disease. According to the Indian Council of Medical Research (ICMR) and the National Family Health Survey (NFHS-5), a significant proportion of India’s working population consumes excess refined carbohydrates, sugar, and unhealthy fats, while falling short on protein, fibre, and essential micronutrients.

For corporate wellness initiatives to create lasting impact, they must move beyond awareness and actively support behaviour change. Dietitian-led virtual cooking classes address this gap by turning nutritional knowledge into daily practice.

Why Nutrition Is a Critical Corporate Wellness Priority

1. Rising lifestyle disease burden among employees

ICMR data highlights the growing health challenge within India’s workforce:

Over 100 million Indians live with diabetes
Nearly one in four adults has hypertension
Obesity rates are rising even among younger professionals

These conditions directly affect productivity, absenteeism, insurance claims, and long-term healthcare costs.

2. Desk-bound and remote work culture

Sedentary routines, irregular meal timings, and reliance on processed or convenience foods have become common in corporate environments, especially with hybrid and remote work models.

3. Knowledge does not translate into action

Many employees are aware of what constitutes healthy eating but struggle to apply this knowledge in everyday cooking. Virtual cooking classes bridge this gap by offering hands-on, real-world guidance.

What Is a Virtual Cooking Class with a Dietitian?

A virtual cooking class with a dietitian is an interactive online session led by a qualified nutrition professional who:

Demonstrates healthy, practical recipes
Explains ingredient choices and substitutions
Teaches portion control and meal balance
Addresses common dietary myths
Answers real-time participant questions

Unlike generic cooking shows or wellness webinars, these sessions are evidence-based and aligned with preventive health goals. They are designed specifically for corporate audiences, ensuring simplicity, cultural relevance, and scalability.

Why Virtual Cooking Classes Work Better Than Traditional Nutrition Talks

1. Practical skill-building

Employees learn how to:

Plan balanced meals
Cook quick, healthy dishes
Reduce excess sugar, salt, and oil
Read food labels with confidence

Skill-based learning leads to stronger habit formation than passive education.

2. Higher engagement and participation

Interactive cooking sessions are:

More engaging than lecture-style talks
Suitable for virtual and hybrid teams
Inclusive across age groups and roles

Participants actively cook, ask questions, and engage rather than passively listening.

3. Cultural relevance

Dietitians tailor recipes to Indian food habits, regional preferences, and household realities, making healthy eating feel practical and sustainable rather than restrictive.

Key Benefits for Employees

Improved daily nutrition

Employees gain confidence in preparing balanced, nourishing meals at home.

Better energy and focus

Stable blood sugar levels and improved nutrient intake support sustained energy and mental clarity during work hours.

Reduced lifestyle disease risk

WHO and Lancet research confirms that dietary improvements significantly reduce the risk of chronic diseases.

Stress reduction

Cooking itself can be therapeutic, contributing positively to mental wellbeing.

Family-wide impact

Healthy habits learned by employees often influence household food choices, extending benefits beyond the workplace.

Why Employers Benefit from Virtual Cooking Classes

1. Reduced absenteeism

Healthier employees tend to experience fewer illness-related absences.

2. Improved productivity

Better nutrition supports cognitive performance, stamina, and focus.

3. Lower long-term healthcare costs

Preventive nutrition initiatives reduce the burden of chronic disease-related claims.

4. Stronger wellness culture

Interactive and practical programs demonstrate genuine employer commitment to employee wellbeing.

5. High return on investment

Compared to large-scale medical interventions, virtual cooking classes are cost-effective, scalable, and easy to implement.

EY–FICCI corporate wellness reports consistently show that nutrition-focused preventive programs deliver higher engagement and long-term impact.

Topics Commonly Covered in Corporate Cooking Classes

Balanced Indian meals
Focus on protein, fibre, and micronutrient adequacy
Quick workday recipes
Healthy meals prepared in under 30 minutes
Disease-preventive diets
Heart-healthy, diabetes-friendly, and weight-conscious cooking
Smart ingredient swaps
Replacing refined grains, excess oil, and added sugar
Portion control techniques
Understanding serving sizes without calorie obsession
Reading food labels
Identifying hidden sugar, sodium, and trans fats

How Virtual Cooking Classes Support Preventive Healthcare

Preventive healthcare focuses on addressing risk factors before disease develops, and nutrition plays a central role in this approach.

According to WHO and NITI Aayog:

Dietary modification is among the most cost-effective preventive strategies
Workplace interventions significantly influence adult eating habits

Virtual cooking classes help:

Reinforce preventive screening insights
Support chronic disease management
Improve adherence to dietitian recommendations

Role of AI-Guided Insights in Corporate Nutrition Programs

Modern wellness programs increasingly use data-driven tools to strengthen impact. AI-enabled health insights can:

Identify common nutritional gaps across employee populations
Personalise dietary recommendations
Support dietitians with evidence-based insights
Track long-term wellness outcomes

This ensures cooking sessions are aligned with real employee health needs rather than generic advice.

Why Virtual Delivery Works Best for Corporates

Easy scalability across multiple locations
No physical infrastructure required
Ideal for remote and hybrid teams
Flexible scheduling
Consistent quality delivery

Virtual formats ensure uniform wellness experiences regardless of employee location.

Long-Term Impact on Corporate Wellness

Organisations that consistently implement nutrition-focused wellness initiatives observe:

Higher employee engagement
Improved biometric health indicators
Reduced burnout
Stronger employer branding

Lancet workplace health studies indicate that nutrition-based interventions show measurable benefits within 6–12 months.

Conclusion

A virtual cooking class with a dietitian is more than a wellness activity—it is a powerful preventive health intervention. By equipping employees with practical nutrition skills, these sessions drive meaningful behaviour change, reduce lifestyle disease risk, and support long-term wellbeing. For organisations seeking impactful, scalable, and evidence-based corporate wellness solutions, dietitian-led virtual cooking classes represent a forward-thinking investment in workforce health.
