Causes of Ankylosing Spondylitis

Introduction

Ankylosing Spondylitis (AS) is an chronic inflammatory condition which primarily affects the sacroiliac joint and spine. In time, it could cause an fusion between vertebrae which can cause a decrease in flexibility, a slumped posture and chronic discomfort. Although researchers have made substantial advancements in the understanding of Ankylosing Spondylitis, the exact causes aren’t fully understood. However, a variety of major causes have been identified as contributing to the chance of growth of this disease.

1. Genetic Factors

A single of the most important connections to ankylosing Spondylitis lies in genes.
The presence of a particular gene known as HLA-B27 is present in over 90percent of patients who suffer from AS.

a. How HLA-B27 Plays a Role :-

• HLA-B27 is one of the genes that assists in controlling immune system reactions.

• For those with AS the gene could trigger an immune system mistakenly attack body’s own tissues, specifically in the spine.

• The presence of HLA-B27 doesn’t guarantee that a person will develop ankylosing Spondylitis. However, it significantly increases the chance.

b. Other Genetic Links :-

• Researchers have discovered over 60 additional genes that could be linked with AS.

• These genes can also impact the function of the immune system and increase the risk of an abnormal inflammation.

c. Family History :-

• Anyone with an parent or a sibling who has ankylosing Spondylitis have a a higher risk.

• The risk is higher in the case of a family member who is a carrier of the gene HLA-B27.

2. Immune System Dysfunction

Ankylosing Spondylitis is thought as an autoinflammatory or autoimmune disorder which means that our immune system attacks the body’s own tissues.

a. How Immune Dysfunction Causes AS :- The immune system becomes extremely active and begins attacking the joints, especially in the area where the spine meets the pelvis. This causes chronic inflammation, which causes stiffness, pain and swelling. In time, the continual process of healing and inflammation could lead to the development of new bone and eventually the fusion of vertebrae in the spinal column.

b. Inflammatory Markers :- Blood tests are often able to detect an increase in amounts of C-reactive protein (CRP) or the erythrocyte sedimentation rates (ESR), both of which are indicators of ongoing inflammation within the body.

c. Misguided Repair Process :- The body is trying to repair the affected areas but instead of replacing the normal tissues, it creates new bone. This bone growth abnormality reduces flexibility and mobility, which leads to the appearance of an stooped posture.

3. Environmental Triggers

Although genetic predisposition is a strong factor, environmental factors are also believed to contribute to the onset of Ankylosing Spondylitis.

a. Possible Environmental Triggers Include :-

• Infections :- There are studies that suggest infections specifically in the urinary or gastrointestinal tract, could be the trigger for the development of AS in people who are genetically susceptible.

• Gut Bacteria :- Unbalances in the gut microbiota (intestinal microbiota) may cause abnormal immune responses that lead in joint pain.

• Physical trauma :- Sometimes injuries or strain to the spine can cause an inflammation reaction, especially for those who are genetically predisposed.

• Smoking :- smoking cigarettes isn’t just a risk factor in developing the disease but increases the likelihood of developing it and the response to treatment.

b. How These Triggers Work :- They could stimulate the immune system of people with the HLA B27 gene. The inadvertent activation of the system can cause chronic inflammation of joints and soft tissues.

4. Hormonal Factors

There is evidence growing of how hormonal fluctuations can affect the severity and development of ankylosing spondylitis.

a. Male Predominance :- Ankylosing Spondylitis is more prevalent for males than females. Men typically have more severe symptoms which suggests testosterone levels in males (like testosterone) may influence disease activity.

b. Female Presentation :- In women, the illness tends to manifest differently, with less spinal fusion, but more involvement of the peripheral joints. Changes in hormones during menopausal and pregnancy may impact the progression of a disease.

c. Possible Hormonal Influence :- Researchers believe that hormonal imbalances may affect immune response, making some people more vulnerable to AS.

5. Other Risk Factors

In addition to genetics, immunity and environmental influences, many other factors can also increase the risk of developing ankylosing Spondylitis.

a. Age :- The symptoms typically start typically in late adolescence or adulthood usually between the age of 17 and 45. It is not common for ankylosing Spondylitis to develop at the age of 45.

b. Ethnicity :- People with European descendance tend to have the gene HLA-B27 and are at a higher risk. The incidence of Ankylosing Spondylitis is lower in African and Asian populations.

c. Family History :- Being a blood relative (parent or sibling) with an Ankylosing Spondylitis increases the risk of developing it significantly.

d. Chronic Stress :- While it isn’t a direct cause stress, chronic stress can exacerbate symptoms. Stress impacts our immune system potentially leading to flare-ups in inflammation.

6. The Connection Between Ankylosing Spondylitis and Gut Health

Recent studies have revealed recent studies show a significant link between inflammation in the gut and Ankylosing Spondylitis.

a. How Gut Health Affects AS :- Patients who suffer from AS typically have subtle, persistent inflammation of the intestines. This can happen even without apparent symptoms of gastrointestinal issues. Conditions such as IBD, also known as Inflammatory Bowel Disease (IBD) and Ankylosing Spondylitis frequently overlap. Unbalanced gut microbiota may disrupt the immunity system leading to joint inflammation.

b. Bacteria and AS :- Certain bacteria, such as Klebsiella have been believed to trigger unnatural immune responses in genetically susceptible people. Research continues to investigate how gut-targeted therapies and probiotics may help in managing AS symptoms in the near future.

Conclusion

The causes of ankylosing Spondylitis are multifactorial and complex that involve a combination of genetic predisposition, immune system dysfunctions as well as environmental triggers and hormonal influences as well as the health of your gut.

Although you can’t completely avoid Ankylosing spondylitis, if you’re genetically predisposed to it, early diagnosis and proactive management could help make a difference. Understanding the root causes aids in developing better treatment strategies as well as adopting lifestyle changes that could help slow the progression of the condition.

If you are experiencing symptoms such as chronic low back stiffness, pain or a hunched position particularly if have a history of it in your family -it’s crucial to talk with an expert. The earlier intervention is the greatest chance to maintain flexibility, relieving pain and living a healthy, active lifestyle despite ankylosing spondylitis.
