Rheumatoid arthritis (RA) is a chronic autoimmune disorder that primarily affects the joints, causing inflammation, pain, and potential joint damage. It occurs when the body's immune system mistakenly attacks the synovial membrane lining the joints. Rheumatoid arthritis can lead to significant disability and reduced quality of life if left untreated.

Rheumatoid arthritis is a debilitating condition that affects millions of people worldwide. It is a chronic autoimmune disease that causes the body's immune system to attack the synovium, the lining of the joints, leading to inflammation, pain, and swelling. If left untreated, RA can cause permanent joint damage and deformity, significantly impacting a person's quality of life. In this article, we will explore the various aspects of rheumatoid arthritis, including its types, stages, and the impact it can have on an individual's life.
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterised by inflammatory arthritis and extra-articular involvement. Unlike osteoarthritis, which is caused by wear and tear on the joints, rheumatoid arthritis is an autoimmune disorder where the body's immune system mistakenly attacks healthy joint tissue. This leads to chronic inflammation, causing pain, stiffness, and swelling in the affected joints. While the exact cause of rheumatoid arthritis remains unknown, it is believed that a combination of genetic and environmental factors may trigger the development of this condition. Recognising the early signs of rheumatoid arthritis is essential for prompt diagnosis and treatment.

There are two main types of rheumatoid arthritis, differentiated by the presence or absence of specific antibodies in the blood:
Seropositive RA: This type is characterised by the presence of specific antibodies in the blood, called rheumatoid factor (RF) and anti-citrullinated protein antibodies (anti-CCP). These antibodies are produced by the immune system and can attack the joints, leading to inflammation and damage. Seropositive RA tends to be more severe and has a poorer prognosis than seronegative RA.
Seronegative RA: This type is characterised by the absence of RF and anti-CCP antibodies in the blood. Despite the lack of these antibodies, seronegative RA still causes inflammation and damage to the joints. Seronegative RA may be more difficult to diagnose, as the absence of antibodies can make it harder to distinguish from other types of arthritis.
Tenderness or pain in small joints, such as those in your fingers or toes
Pain in larger joints, like your knee or shoulder
Fatigue or feeling extremely tired and lacking energy
Slight fever or a slightly raised temperature
Unexplained weight loss, possibly due to inflammation
Joint stiffness, particularly in the morning or after periods of inactivity
Swelling and redness in the affected joints
Rheumatoid arthritis symptoms can vary among individuals and may come and go. The most common symptoms include:
Joint pain and stiffness: Typically, rheumatoid arthritis affects smaller joints, such as those in the hands and feet. Symptoms often worsen in the morning or after periods of inactivity.
Swelling and inflammation: Affected joints may appear swollen, red, and warm to the touch due to inflammation, which can limit mobility and function.
Fatigue: Many individuals experience a pervasive feeling of tiredness that impacts daily activities, often linked to the body’s inflammatory response.
Fever: Low-grade fever may occur during flare-ups, indicating the body’s immune response.
Loss of appetite: Reduced desire to eat can lead to weight loss and is often associated with inflammation and overall fatigue.
Joint deformities: Over time, persistent inflammation can lead to joint damage and deformities, particularly in the hands and feet.
Systemic symptoms: Rheumatoid arthritis can also affect other body systems, leading to symptoms like dry eyes or mouth, anaemia, and lung issues, reflecting the systemic nature of the autoimmune response.
Rheumatoid arthritis typically progresses through four stages:
Stage 1 (early RA): The earliest stage of rheumatoid arthritis, known as synovitis, involves inflammation of the synovial membrane, resulting in joint swelling and pain. Early diagnosis and intervention at this stage can significantly improve outcomes and prevent further joint damage.
Stage 2 (moderate RA): As the disease progresses, the inflamed synovial membrane thickens and forms pannus, a fibrous tissue that invades and erodes the cartilage and bone within the joint. Without adequate treatment, joint damage can become irreversible at this stage.
Stage 3 (severe RA): In stage 3, the erosion of cartilage and bone leads to joint deformities and loss of joint function. Patients may experience increased pain, stiffness, and difficulty performing daily activities.
Stage 4 (end-stage RA): The final stage of rheumatoid arthritis is characterised by severe joint destruction, loss of mobility, and significant disability. At this stage, joint replacement surgery may be necessary to restore function and alleviate pain.
While the triggers for this autoimmune reaction are unclear, it is thought that a combination of genetic and environmental factors may be responsible, which include:
Genetic factors: Certain genes, such as the HLA (human leukocyte antigen) genes, can increase susceptibility to rheumatoid arthritis, although having these genes doesn't necessarily mean you will develop the condition.
Environmental factors: Some environmental exposures, like cigarette smoking, air pollution, and certain infections, may trigger rheumatoid arthritis in genetically susceptible people.
Hormones: Hormonal changes, like those during pregnancy, may play a role in the development of rheumatoid arthritis, which is more common in women.
Several factors can increase the likelihood of developing rheumatoid arthritis, including:
People aged 30-60
Gender (women more likely than men)
Family history
Smoking
Obesity
Exposure to certain toxins, such as asbestos or silica dust
Chronic gum inflammation
Rheumatoid arthritis can lead to several complications if not managed effectively. Some of the key complications associated with rheumatoid arthritis include:
Joint damage: Rheumatoid arthritis can cause inflammation in the joints, resulting in damage to the cartilage, bone, and ligaments. This may lead to joint deformity, loss of function, and chronic pain.
Osteoporosis: Chronic inflammation and certain medications used to treat rheumatoid arthritis, such as corticosteroids, can increase the risk of osteoporosis, which is characterised by weakened bones and a higher risk of fractures.
Heart disease: People with rheumatoid arthritis have a higher risk of developing heart disease, including conditions like coronary artery disease, heart failure, and stroke, partly due to the chronic inflammation associated with rheumatoid arthritis.
Lung disease: Rheumatoid arthritis can affect the lungs, leading to conditions such as interstitial lung disease (ILD) and rheumatoid nodules in the lungs, which can impair lung function and overall health.
Eye problems: Rheumatoid arthritis can cause various eye problems, including dry eyes, scleritis (inflammation of the white part of the eye), and uveitis (inflammation of the uvea, the middle layer of the eye).
Increased risk of infections: People with rheumatoid arthritis have a higher risk of infections, partly due to the dysfunction of the immune system and the use of immunosuppressive medications.
Diagnosing rheumatoid arthritis involves a combination of clinical evaluation, laboratory tests, and sometimes imaging studies. The diagnostic process typically includes:
Clinical evaluation: The diagnosis starts with a thorough medical history and physical examination. The doctor will assess the patient's symptoms, such as joint pain, stiffness, and swelling, and look for signs of inflammation, joint deformity, and reduced range of motion.
Blood tests: Key diagnostic markers for rheumatoid arthritis include rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies, with the latter being more specific to the condition. Additionally, inflammatory markers such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are often elevated in individuals with rheumatoid arthritis.
Imaging tests: X-rays, ultrasound, and magnetic resonance imaging (MRI) can help assess joint damage and inflammation and monitor disease progression.
Synovial fluid analysis: In some cases, fluid from the affected joint may be extracted and analysed for signs of inflammation and to rule out other conditions, such as gout or infection.
Treatment for rheumatoid arthritis is multifaceted and aims to reduce inflammation, alleviate pain, and prevent or slow joint damage. The key components of rheumatoid arthritis treatment include:
Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) help reduce pain and inflammation. Disease-modifying anti-rheumatic drugs (DMARDs) like methotrexate and sulfasalazine are crucial for slowing disease activity and preventing joint damage. Biologics and JAK inhibitors are used when DMARDs are not effective. Corticosteroids provide short-term pain relief and reduce inflammation, while analgesics manage pain when NSAIDs are unsuitable.
Physical and occupational therapy: Physical therapy improves fitness, muscle strength, and joint flexibility, while occupational therapy assists patients in managing daily tasks and provides advice on protecting joints.
Exercise: Regular physical activity, such as walking, swimming, and low-impact aerobics, is essential for preserving joint mobility, strengthening muscles, and improving overall health.
Surgery: In some cases, surgery may be necessary to correct joint damage or improve joint function.
Living with rheumatoid arthritis can be challenging, but there are several strategies that can help patients manage their symptoms and maintain a good quality of life. These include:
Engage in regular, low-impact exercises like swimming, walking, or cycling to maintain joint flexibility and muscle strength.
Excess weight can put additional stress on joints, so maintaining a healthy weight through a balanced diet and regular exercise is essential.
Gadgets and tools like jar openers, ergonomic kitchen utensils, and walking aids can help make daily tasks easier and reduce strain on joints.
Stress can worsen rheumatoid arthritis symptoms, so finding ways to manage stress, such as through relaxation techniques, meditation, or counselling, is important.
Fatigue is a common symptom of rheumatoid arthritis, so getting adequate rest and sleep is crucial for managing the disease.
Joining a support group or talking to friends and family about the challenges of living with rheumatoid arthritis can provide emotional support and practical advice.
If you experience symptoms suggestive of rheumatoid arthritis, such as joint pain, stiffness, swelling, and fatigue, it is important to consult a doctor, preferably a rheumatologist, for an accurate diagnosis and appropriate treatment. Additionally, if you have been diagnosed with rheumatoid arthritis, you should see your doctor regularly for monitoring and adjusting your treatment plan as needed. Contact your doctor promptly if you experience a flare-up of symptoms, new or worsening joint pain, or any other concerning symptoms.
