Description

Rheumatoid Arthritis (RA) is a chronic autoimmune disease that mostly affects the joints. Joints tend to become warm, swollen, and painful as a result. Rest often makes stiffness and pain worse. The wrist and hands are the most common areas affected, and the same joints are typically involved on both sides of the body. Other parts of the body, such as the skin, eyes, lungs, heart, nerves, and blood, may also be affected by the disease. Lung and heart inflammation, as well as a low red blood cell count, may be the consequences of this. There may also be fever and low energy. Frequently, symptoms appear gradually over several weeks or months.

Rheumatoid arthritis is thought to be caused by a combination of genetic and environmental factors, although the exact cause is unknown. The immune system of the body attacks the joints as the underlying cause. The joint capsule thickens and becomes inflamed as a result. It also affects the cartilage and bone beneath. The majority of the time, signs and symptoms are used to make a diagnosis. Laboratory tests and X-rays can either confirm or rule out other diseases with similar symptoms. Systemic lupus erythematous, psoriatic arthritis and fibromyalgia are among the other conditions that may present similarly.

The most common non-joint feature of Rheumatoid Arthritis (RA) is the rheumatoid nodule, which can be found on the skin. It affects 30% of RA patients. Pathologists refer to this type of inflammatory reaction as a "necrotizing granuloma." Despite the fact that nodule formation and synovitis share many of the same structural characteristics, the initial pathologic process may be similar. Fibrinoid-rich necrotic material can be found in and around affected synovial spaces, so the nodule has a central area of fibrinoid necrosis that may be fissured. A layer of palisading macrophages and fibroblasts, near to the intimal layer in synovium, and a cuff of connective tissue, related to the subintimal zone in synovitis, with clusters of lymphocytes and plasma cells, surround the necrosis.

Signs and symptoms

RA mostly affects the joints, but more than 15%–25% of the time, it also affects other organs. Cardiovascular disease, osteoporosis, interstitial lung disease, infection, cancer, fatigue, depression, mental issues, and difficulty working are all associated issues.

•Swelling, joint stiffness and less energy

• Pain in the joints

• Tingling and numbness

• Fever

Most of the time, RA attacks multiple joints at once. Joints in the hands, wrists, and knees are frequently affected by RA. The inflammation of the joint's lining in people with RA damages the joint tissue. Unsteadiness (loss of balance), deformity (misshapenness), and chronic or long-lasting pain are all possible outcomes of this tissue damage. Other body tissues and organs, such as the lungs, heart, and eyes, can also be affected by RA.

What is rheumatoid arthritis's primary cause?

The synovial membrane is inflamed in arthritis of the joints. Stiffness restricts joint movement and causes swelling, tenderness, and warmth in the joints. Polyarthritis affects multiple joints over time. Small joints like the hands, feet, and cervical spine are most commonly affected, but larger joints like the shoulder and knee can also be affected. The tissue can become tethered, resulting in loss of movement, and the joint surface can be eroded, resulting in deformity and function loss. The synovial membranes highly specialized mesenchyme cells called Fibroblast-Like Synoviocytes (FLS), play a significant and active role in these rheumatic joint pathologies. Swollen, warm, painful, and stiff joints are typical symptoms of rheumatoid arthritis, especially when first waking up or after a long period of inactivity.

In the early stages of RA disease, gentle movements may alleviate symptoms. These symptoms help differentiate rheumatoid from non-inflammatory joint conditions like osteoarthritis. The early morning stiffness and signs of inflammation are less noticeable in arthritis of non-inflammatory origin. As an autoimmune condition, rheumatoid arthritis is brought on by the immune system attacking healthy body tissue. However, the cause of this is unknown at this time. Antibodies are normally produced by people immune system to combat infection. These antibodies target viruses and bacteria.
