Rheumatoid Arthritis is a chronic autoimmune disorder characterized by the immune system mistakenly attacking the linings of the joints (synovium). This causes painful swelling, which eventually leads to bone erosion and joint deformity.
read more about rheumatoid arthritis ...The role of the autoimmune system is central; it attacks the synovium, causing continuous inflammation that thickens the joint lining. This process is driven by immune cells releasing enzymes that damage the surrounding cartilage and bone over time, which is the mechanism of irreversible joint destruction. This process is typically symmetrical, affecting the same joints on both sides of the body, such as the hands, wrists, and feet, distinguishing it from other types of arthritis.
Symptoms include painful, tender, swollen joints, often affecting the smaller joints first (hands and feet). Stiffness is profound, especially in the morning and after long periods of rest. This debilitating morning stiffness can last for several hours, distinguishing it from the brief stiffness associated with mechanical joint issues like osteoarthritis. The inflammation restricts the range of motion, making simple tasks difficult.
Diagnosis involves a physical exam and blood tests to check for specific antibodies and high levels of inflammatory markers. Imaging tests (X-rays and ultrasound) are used to track joint damage over time.
Rheumatoid Arthritis frequently impacts eye health due to systemic inflammation. Patients often develop severe dry eyes (Sj?gren's syndrome is common), episcleritis, and, in rare cases, scleritis, which causes severe pain and vision loss.
Management strategies focus on controlling inflammation. This involves anti-inflammatory drugs (non-steroidal anti-inflammatory drugs) and Disease-Modifying Anti-Rheumatic Drugs (DMARDs), which slow the progression of joint damage.
No, osteoarthritis is wear-and-tear. Rheumatoid Arthritis (RA) is an autoimmune disease.
No, unlike mechanical pain, the stiffness is worst after rest (in the morning) and improves with activity.
Yes, RA is a systemic disease and can affect the skin, lungs, blood vessels, and eyes.
If you have RA, you must monitor for "Scleromalacia Perforans", a serious condition where the white part of the eye thins due to inflammation. If your eye looks "blue" or you have severe pain, seek emergency care. Many RA medications (like Hydroxychloroquine) also require annual retinal screenings.
