Rheumatoid arthritis is a chronic inflammatory disorder. It affects the small joints in your hands and feet. Rheumatoid arthritis typically affects the lining of joints, causing a painful swelling that may result in bone erosion and joint deformity. RA is one of the most common autoimmune disorder, occurs when your immune system mistakenly attacks your own body’s tissues. RA can affect other organs of the body such as the skin, eyes, heart, kidney, lungs and blood vessels.
Science and Symptoms
Science of RA
The exact cause is unknown, a genetic component appears likely.
Rheumatoid arthritis occurs when your immune system attacks the synovium, which is the lining of the membranes that surround your joints.
The resulting inflammation thickens the synovium, which can eventually destroy the cartilage and bone within the joint.
The tendons and ligaments that hold the joint together get weaken and gradually, the joint loses its shape and alignment.
Environmental factors such as infection with certain viruses and bacteria may trigger the disease.
Signs and symptoms of rheumatoid arthritis may include:
Tender, warm, swollen joints
Morning stiffness that may last for hours
Firm bumps of tissue under the skin on your arms (rheumatoid nodules)
Fatigue, fever and weight loss
Early rheumatoid arthritis tends to affect your smaller joints first — particularly the joints that attach your fingers to your hands and your toes to your feet. As the disease progresses, symptoms often spread to the wrists, knees, ankles, elbows, hips and shoulders. In most cases, symptoms occur in the same joints on both sides of your body. Rheumatoid arthritis signs and symptoms may vary in severity and may even come and go. Factors that may increase your risk of rheumatoid arthritis include:
Sex. Women are more likely to develop rheumatoid arthritis.
Age. Rheumatoid arthritis can occur at any age, but it most commonly begins between the ages of 30 and 50.
Family history. If a member of your family has rheumatoid arthritis, you may have an increased risk of the disease.
How it is diagnosed?
Rheumatoid arthritis can be difficult to diagnose in its early stages. There is no one blood test or physical finding to confirm the diagnosis.
During the physical exam, your doctor will check your joints for swelling, redness and warmth. He will also check your reflexes and muscle strength.
People with rheumatoid arthritis tend to have an elevated erythrocyte sedimentation rate (ESR), which indicates the presence of an inflammatory process in the body.
Other common blood tests look for rheumatoid factor and anti-cyclic citrullinated peptide (anti-CCP) antibodies.
Your doctor may recommend X-rays to help track the progression of rheumatoid arthritis in your joints over time.
The goals of treatment are to minimize symptoms such as pain and swelling, to prevent bone deformity and improve your quality of life. You may need stronger drugs or a combination of drugs if your disease progresses.
