Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disorder that primarily affects joints. However, it is not limited merely to the joints. It occurs when the body’s own immune system mistakenly begins to attack the joints. This causes inflammation of the joint, making it red, warm, swollen, and painful (hence named as arthritis). What triggers this autoimmune reaction is not known. An external trigger like cigarette smoking, trauma, or infection might play a role.
RA can involve any joint, but it usually starts in the small hand joints. Other joints commonly affected include those of knees, hips, ankles, feet, elbows, neck, and shoulders.
Women are more likely to be affected from RA than men are.
Signs and Symptoms of RA
In addition to joint pain and inflammation, people affected by RA present with the following signs and symptoms:
Articular (related to joint) manifestations
Limitation of movement.
A general feeling of being unwell.
Skin involvement .
Skin ulceration: Secondary to inflammation of blood vessels (vasculitis) supplying the limbs.
Pyoderma gangrenosum: A condition that causes the development of massive, painful sores (ulcers) on the skin, mostly on the legs.
Pleuritis: Inflammation of the covering of the lungs.
Pleural effusion: Collection of fluid within the pleura.
Felty's syndrome: A constellation of RA, splenomegaly, and neutropenia.
Diagnosis of RA
There is no unique test or sign that is pathognomonic for RA. The patient has rheumatoid arthritis if he or she meets at least four of these seven criteria.
- Morning stiffness
Arthritis of three or more joint areas.
Arthritis of hand joints.
Morning stiffness in and around the joints.
Lasting at least 1 hour prior to maximal improvement.
Radiographic changes typical of rheumatoid arthritis
Serum rheumatoid factor.
ACPA – "ACPA" stands for "anti-citrullinated protein antibody.
RA leads to deformed joints with restricted movements and functionality. Thus, treating RA is of utmost importance. Analgesics like NSAIDs may ease the pain and inflammation of joints. Steroids and disease-modifying agents ameliorate symptoms and slow the progression of the disease.
