What Is Rheumatoid Arthritis?
Rheumatoid arthritis (RA) is an autoimmune disorder that causes chronic inflammation and pain in the joints throughout the body. It is a long-term and disabling disease.
This disease usually affects the joints of the hands and feet first, and if one side of the joint is affected, it is most likely to affect the joint on the other side also.
What Are the Types of Rheumatoid Arthritis?
The common types of RA are:
-
Seropositive rheumatoid arthritis - 60 to 80 % of patients test positive for antibodies called anti-cyclic citrullinated peptides (anti-CCPs) or rheumatoid factor (RF).
-
Seronegative rheumatoid arthritis - Patients test negative for anti-CCPs and rheumatoid factors but still show symptoms of RA.
What Is an Autoimmune Disorder?
The immune system prevents diseases by attacking the virus or bacteria or any foreign objects that enter the body. When this immune system starts identifying the cells of the body as foreign objects, they start attacking them, which leads to autoimmune disorders or diseases.
What Are the Signs and Symptoms of Rheumatoid Arthritis?
The signs of rheumatoid arthritis are:
-
Pain, tenderness, stiffness, swelling, redness, and warmth on involved joints, usually in a symmetrical manner.
-
Walking with a limp.
-
Loss of joint function.
Small joints like the joints in the fingers and toes are usually affected first. In the later stages, it spreads to the wrist, knee, ankle, hips, shoulders, and elbows.
The symptoms aggravate during periods known as flares, and during the remission period, the symptoms disappear. The symptoms can be mild to severe for different patients.
How Do You Get Rheumatoid Arthritis?
When the immune system attacks the membrane lining the joints (synovium), it leads to inflammation and thickening of the synovium. This inflammation eventually affects the cartilage and bone in the joint. The tissues that hold the bones in the joint together (ligaments and tendons) stretch and weaken, making the joints lose their shape and alignment.
Pathophysiology:
The three phases in which RA progresses are:
-
Initiation phase.
-
Amplification phase.
-
Chronic inflammatory phase.
What Is the Difference Between Osteoarthritis and Rheumatoid Arthritis?
What Are the Risk Factors for Rheumatoid Arthritis?
Factors that increase the risk of an individual acquiring RA are:
-
Age - Its onset is highest in older adults (60 years and above), but it can begin at any age.
-
Sex - Women are two-to-three more prone than men.
-
Women who have never given birth.
-
Children of mothers who smoked while pregnant.
-
Genetics - Individuals born with the HLA (human leukocyte antigen) gene are more susceptible. This, along with exposure to environmental factors, can increase the risk of RA.
-
Smoking.
-
Obesity.
What Are the Stages of Rheumatoid Arthritis?
-
Stage 1 -Early Stage Rheumatoid Arthritis - Joint pain, stiffness, or swelling. No damage to the bones and only the tissue lining the joint (synovium) is inflamed.
-
Stage 2 - Moderate Stage Rheumatoid Arthritis - The joint cartilage gets damaged due to inflammation of the synovium. This results in joint pain and loss of mobility.
-
Stage 3 - Severe Stage Rheumatoid Arthritis - In this stage, the bone also gets damaged. This results in severe pain and swelling, more loss of mobility, and bone deformity.
-
Stage 4 - End-stage Rheumatoid Arthritis - The joints do not work, resulting in pain, stiffness, swelling, and loss of mobility. The bones might also fuse together (ankylosis).
What Are the Complications and Conditions Associated with RA?
It has been noted that people with RA commonly develop the following conditions:
-
Osteoporosis - The bone becomes porous and prone to fractures.
-
Rheumatoid nodules - Firm lumps under the skin near the joints that are affected by RA.
-
Sjogren’s syndrome - An autoimmune condition where the cells of the immune system attack the glands that produce tears and saliva.
-
Frequent infections.
-
Atherosclerosis - A condition where fat or plaque builds up inside the arteries.
-
Lymphoma - A type of cancer that originates in the lymphocytes.
-
Carpal tunnel syndrome - Otherwise called median nerve compression, results in pain and numbness in the hand and arm.
-
Cervical myelopathy - It is a degenerative condition that results from compression of the spinal cord.
-
Depression and anxiety.
How Is Rheumatoid Arthritis Diagnosed?
Diagnosis of RA needs a lot of blood tests and imaging. If you have symptoms of RA, consult a rheumatologist. The doctor will ask you about the symptoms you are having and will conduct a few physical examinations. The doctor will look for redness, tenderness, and warmth in the affected joint. To rule out all other causes and to check the damages done to your bones, he or she might order some blood and other tests.
You might have to get the following tests done:
-
Blood test - A blood test is done to look for the presence of rheumatoid factor and anti-CCP antibodies. C-reactive protein and erythrocyte sedimentation rate (ESR) are also elevated in RA patients.
-
Imaging tests - X-rays, MRI, and ultrasound are done to see the progression of the disease.
How to Treat Rheumatoid Arthritis?
Starting medicines early keep the disease in remission period. The treatment options include:
Medicines:
-
Nonsteroidal anti-inflammatory drugs (NSAIDs) - Ibuprofen and Naproxen sodium to reduce pain.
-
Corticosteroids - Prednisone helps reduce inflammation and slows the progression of joint damage.
-
Disease-modifying antirheumatic drugs (DMARDs) - Methotrexate, Leflunomide, and Sulfasalazine reduces the progression of this disease.
-
Biologic response modifiers - Abatacept, Adalimumab, Infliximab, Rituximab, Etanercept, etc., are a new class of DMARDs.
Occupational Therapy:
An occupational therapist will teach exercises to make your joint more flexible and easier ways to do day-to-day activities.
Surgery:
In case your symptoms are not getting better with medicines and therapies, your doctor might suggest you undergo the following surgeries to repair damaged joints:
-
Synovectomy - The inflamed synovium is removed.
-
Tendon repair - The inflamed and loosened or ruptured tendons are repaired.
-
Joint replacement - Damaged joints are replaced by prostheses.
-
Joint fusion - When replacement cannot be done, the joints are fused together to reduce pain.
Lifestyle Changes:
-
Perform regular gentle exercises like walking, swimming, water aerobics, etc.
-
Apply heat and cold compressions.
-
Manage stress through yoga and meditation.
What Foods to Avoid and Eat If You Have Rheumatoid Arthritis?
Diet might not help treat RA, but some food items might cause flares, and others might help reduce inflammation.
Foods to avoid:
-
Red meat.
-
Dairy.
-
Corn oil.
-
Fried and processed food.
-
Too much salt and sugar.
-
Alcohol.
Food to eat:
-

-
Beans.
-
Citrus fruits.
-
Ginger.
-
Nuts.
-
Whole grains.
-
Olive oil.
