Causes, Effects and Treatment of Rheumatoid Arthritis (RA)
Rheumatoid arthritis (RA) is a chronic autoimmune disease
that primarily affects the joints. The details about cause, effects, preventions,
diagnosis, treatment and future directions are as below –
Rheumatoid arthritis (RA)
1. Introduction of Rheumatoid Arthritis (RA):
Rheumatoid arthritis (RA) is a complex and chronic autoimmune disease that predominantly targets the joints. It affects people of all ages, but it is most common among women between the age 30 and 60 years. RA is characterized by chronic inflammation in the synovium, which is the limning of the membranes that surround the joints. This inflammation can lead to joint damage, pain and disability.
2. Cause of Rheumatoid Arthritis:
The exact cause of rheumatoid arthritis is not fully understood but several factors are believed to contribute to its development -
a) Autoimmunity – RA is an autoimmune disease, which can mean that the body’s immune system mistakenly attacks its own tissues. In the case of RA, the immune system primarily targets the synovium leading to inflammation.
b) Genetic factors – There is a genetic disposition to RA. Certain genetic markers, such as the HLA-DRB1 gene, have been associated with an increased risk of developing the disease.
c) Environmental Triggers – Environmental factors, such as infections, smoking and hormonal changes triggers the onset of RA in individuals with a genetic predisposition.

3. Effects of Rheumatoid Arthritis:
RA can have widespread effects on the body, not limited to joints.
a) Joint Pain and swelling – The hallmark of RA is joint pain, stiffness and swelling can affect multiple joints including the wrists, knees, fingers and elbow.

b) Joint Damages – Over time, the inflammation in the synovium can lead to joint damage and deformities. This can significantly impair a person’s mobility and quality of life.
c) Systemic Effects – RA can also affect various organs and system in the body. It can lead to inflammation in the eyes, heart, lungs, skin and blood vessels.
d) Fatigue – People with RA often experience profound fatigue, which can be debilitating and impact daily activities.
e) Decreased Quality of Life – RA can lead to a decreased quality of life due to pain, disability and limitations in performing daily tasks and activities.
4. Prevention of Rheumatoid Arthritis:
While there is no guaranteed way to prevent rheumatoid arthritis, there are some strategies that may reduce the risk or delay the onset of the disease.
a) Healthy Lifestyle – Maintaining a healthy lifestyle that includes a balanced diet, regular exercise and avoiding smoking can help reduce risk of RA.
b) Early Diagnosis and Treatment – Early diagnosis and prompt treatment can prevent the progression of RA and reduce the risk of joint damage. If you experience joint pain or stiffness, consult a healthcare professional.
c) Genetic Testing – Individuals with a family history of RA may consider genetic testing to assess their risk. However, genetic testing is not foolproof and can only provide an estimate of risk.

5. Diagnosis of Rheumatoid Arthritis:
Diagnosing rheumatoid arthritis involves a combination of clinical evaluation, medical history and laboratory tests. The following steps are typically taken to diagnosis RA -
a) Medical History – The doctor will discuss your symptoms, including the location and duration of joint pain and stiffness.
b) Physical Examination – A physical examination is performed to assess joints swelling, warmth and tenderness. The doctor may also check for joint deformities.
c) Imaging – X-rays, ultrasound or MRI scans may be used to assess joint damage and inflammation.
d) Blood Tests – Several blood tests are commonly used to diagnose RA. These include tests for rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies. Elevated levels of these markers can indicate RA.

6. Treatment of Rheumatoid Arthritis:
The management of rheumatoid arthritis aims to reduce pain, inflammation, prevent joint damage and improve the quality of life. Treatment options include -a) Medications –
i) Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) – These drugs can help reduce pain and inflammation but do not show the progression of these disease.
ii) Disease-Modifying Antirheumatic Drugs (DMARDs)- These drugs, such as methotrexate ands sulfasalazine, can slow down the progression of RA by suppressing the immune system’s activity.
iii) Biologic DMARDs – These newer medications target specific molecules involved in the inflammatory process. Examples include etanercept and adalimumab.
iv) Corticosteroids – These are potent anti-inflammatory drugs that can rapid relief from symptoms but are usually used in the short-term due to potential side effects.
b) Physical Therapy –
Physical therapy can help improve joint function and reduce pain. Exercise and techniques that promote joint flexibility and strength are often prescribed.
c) Surgery –
In severe cases where joints damage is extensive, surgical interventions like joints replacement surgery may be necessary to restore mobility and reduce pain.
d) Lifestyle Modifications –
Lifestyle changes, such as weight management, rest and joint protection techniques can help manage RA symptoms and reduce the strain on affected joints.
e) Complementary Therapies –
Some individuals find relief from RA symptoms through complementary therapies like acupuncture, massage and dietary supplements. It’s essential to discuss these with a healthcare provider.
7. Disease Monitoring:
Rheumatoid arthritis is a chronic condition that requires ongoing management and monitoring. Regular follow-up with a healthcare provider is a crucial to assess the disease’s progression and the effectiveness of treatment. Monitoring includes
a) Clinical Evaluation – Regular check-ups to assess joints pain, function and overall well-being.
b) Imaging – Periodic imaging studies to monitor joints damages.
c) Laboratory Tests – Blood tests to check for inflammation markers and assess the response to treatment.
8. Coping with Rheumatoid Arthritis:
Coping with RA can be challenging, but several strategies can help individuals manage the disease and improve their quality of life –
a) Support Networks – Joining support groups or seeking support from friends and family can provide emotional and practical assistance.
b)Pain Management Techniques – Learning and practicing pain management techniques, such as relaxation, mindfulness and deep breathing can help individuals cope with chronic pain.
c) Adaptive Aids – Using assistive devices like braces, splints and mobility aids can make daily activities more manageable.
d) Work and Disability – Communicate with your employer about workplace accommodations if needed and consider applying for disability benefits if RA affects your ability to work.
9. Research and Future Directions:
Ongoing research in rheumatoid arthritis is focused on improving the understanding of the disease and developing more effective treatments. Some key areas of research include –
a) Personalized Medicine – Tailoring treatment to an individual’s genetic and immune system characteristics to optimize outcomes.
b) Biologic Therapies – Continuing to develop new biologic DMARDs with different mechanisms.
