Understanding the Link between Autoimmune Diseases and COVID

The COVID-19 pandemic, triggered by the novel coronavirus SARS-CoV-2, has shed light on the complex interplay between infectious diseases and pre-existing health conditions, including autoimmune disorders. As we continue to explore this relationship, it has become clear that individuals with autoimmune conditions may encounter distinct challenges when confronted with COVID-19.

What are Autoimmune Diseases?

Autoimmune diseases arise when the immune system, which is intend to protect the body against foreign substances, mistakenly targets healthy cells and tissues. This results in an inappropriate and harmful immune response, leading to a variety of conditions, such as rheumatoid arthritis, lupus, and multiple sclerosis.

How Does the Immune System Work?

The immune system, a sophisticated network of cells and organs, acts as the body’s protective barrier against harmful substances. However, in autoimmune disorders, this system fails to function properly, leading to a range of symptoms that can affect different organs and tissues throughout the body.

COVID-19 and Immune Response

When the coronavirus infects the body, the immune system springs into action to combat the threat. However, in some instances, this response can lead to an overactive inflammatory response, which can have varying effects on individuals depending on their immune system’s overall health.

Autoimmune diseases develop when the immune system, which is supposed to protect the body, mistakenly attacks and damages its own cells, leading to inflammation and tissue damage. The connection between autoimmune diseases and COVID-19 has been the focus of scientific investigation since the pandemic began.

Individuals with autoimmune conditions might be more susceptible to severe illness from COVID-19 due to their immune system’s unusual response to the virus. In people with autoimmune diseases, the immune system’s overactivity or dysregulation can intensify the body’s reaction to the virus, resulting in more severe symptoms and complications.

Autoimmune diseases symptoms

Autoimmune diseases can present a wide range of symptoms. It is depending on the specific condition and the part of the body affected.

  • Persistent tiredness or a lack of energy, which can be debilitating.
  • Inflammation in the joints leading to pain, stiffness, and swelling.
  • Aches, weakness, or muscle tenderness.
  • Raised body temperature, often intermittent or persistent.
  • Rashes, redness, or changes in skin texture.
  • Sudden or gradual loss of hair on the scalp or other parts of the body.
  • Inflammation or swelling in various parts of the body.
  • Cognitive difficulties, memory problems, or brain fog.

Some common Autoimmune diseases

There are numerous types of autoimmune diseases

Rheumatoid Arthritis:

Arthritis can have a significant impact on the joints, leading to inflammation, pain, and potential damage to the joint itself.

Systemic Lupus Erythematosus (SLE):

This condition impacts various bodily systems, resulting in a range of symptoms .It is like  joint discomfort, skin rashes, exhaustion, and organ inflammation.

Multiple Sclerosis (MS):

Affects the central nervous system, causing damage to the protective covering of nerve fibers, leading to various neurological symptoms.

Hashimoto’s Thyroiditis:

Targets the thyroid gland, causing hypothyroidism (underactive thyroid).


Causes loss of skin color due to the immune system attacking pigment-producing cells.

Impact of COVID-19 on Specific Autoimmune Diseases

The impact of COVID-19 on specific autoimmune diseases can vary, but generally, individuals with autoimmune conditions may face different challenges when infected with COVID-19:

Inflammatory Bowel Disease (IBD):

Individuals with inflammatory bowel disease (IBD) may be more susceptible to severe COVID-19 due to alterations in their immune system and the use of immunosuppressive medications. The severity of this association can vary depending on the level of disease activity and specific treatment being used.

Psoriasis and Psoriatic Arthritis:

The severity of COVID-19 in people with psoriasis or psoriatic arthritis may be influenced by the level of disease activity and specific treatments they are receiving. Certain medications used to manage these conditions, such as biologics, may potentially impact the immune response to the virus, which could affect the severity of the illness.

Type 1 Diabetes and Thyroid Disorders:

Individuals with pre-existing autoimmune conditions, such as diabetes or thyroid disorders. It  may be more susceptible to COVID-19-related complications due to the virus’s potential impact on their blood sugar levels or thyroid function.


The exact causes of autoimmune diseases aren’t fully understood, but they’re believed to involve a combination of genetic, environmental, and immunological factors:

Genetic Predisposition:

Research suggests that there may be a genetic component to autoimmune diseases, where certain genetic factors can heighten the likelihood of developing these conditions. However, it’s important to note that possessing these genes does not automatically lead to the development of an autoimmune disease.

Environmental Triggers:

Various environmental factors can play a role in triggering autoimmune responses in genetically susceptible individuals. These triggers might include infections (viral or bacterial), certain medications, chemical exposure, or dietary factors.

Immunological Factors:

Autoimmune diseases arise when the immune system mistakenly identifies the body’s own cells or tissues as foreign and mounts an immune response against them. This can occur due to problems with immune system regulation, such as a lack of ability to distinguish between self and non-self, leading to an inappropriate immune response.

Hormonal Factors:

Hormones play a significant role in the immune system, and fluctuations in hormone levels, particularly estrogen, may contribute to the onset or worsening of autoimmune diseases. Autoimmune diseases are more common in women than men, and hormonal changes may be a factor in this disparity.


Stress and other psychological factors may not directly cause autoimmune diseases, but they can still play a role in exacerbating or triggering flare-ups by affecting the immune system’s function.

Some common types of medications include:

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs):

Medications such as ibuprofen or naproxen are commonly used to alleviate pain, inflammation, and fever associated with various conditions, including rheumatoid arthritis and lupus. These drugs are designed to manage symptoms and provide relief to individuals suffering from these conditions.

Disease-Modifying Antirheumatic Drugs (DMARDs):

These medications, such as methotrexate, hydroxychloroquine, or sulfasalazine, work by suppressing the immune system and reducing inflammation to slow the progression of certain autoimmune diseases. They are commonly used to treat conditions like rheumatoid arthritis or psoriatic arthritis

Janus Kinase (JAK) Inhibitors:

Newer medications, such as tofacitinib, work by targeting specific enzymes in the immune system called Janus kinases (JAKs). By inhibiting these enzymes, these medications can help reduce inflammation and manage conditions like rheumatoid arthritis or psoriatic arthritis.

How to Managing Autoimmune Conditions During the Pandemic

Here are some tips to help navigate this situation:

  • To minimize the risk of contracting the virus, it is essential to adhere to established safety protocols.
