There is no singular test for diagnosing rheumatoid arthritis. Instead, rheumatoid arthritis is diagnosed based on a combination of the presentation of the joints involved, characteristic joint stiffness in the morning, the presence of blood rheumatoid factor and
citrulline antibody, as well as findings of rheumatoid nodules and radiographic changes (X-ray testing).
The first step in the diagnosis of rheumatoid arthritis is a meeting between the doctor and the patient. The doctor reviews the history of symptoms, examines the joints for inflammation, tenderness, swelling, and deformity, the skin for rheumatoid nodules (firm bumps under the skin, most commonly over the elbows or fingers), and other parts of the body for inflammation. Certain blood and X-ray tests are often obtained. The diagnosis will be based on the pattern of symptoms, the distribution of the inflamed joints, and the blood and X-ray findings. Several visits may be necessary before the doctor can be certain of the diagnosis. A doctor with special training in arthritis and related diseases is called a
rheumatologist.
The distribution of joint inflammation is important to the doctor in
making a diagnosis. In rheumatoid arthritis, the small joints of the
hands, wrists, feet, and knees are typically inflamed in a symmetrical
distribution (affecting both sides of the body). When only one or two
joints are inflamed, the diagnosis of rheumatoid arthritis becomes more
difficult. The doctor may then perform other tests to exclude arthritis
due to infection or gout. The detection of rheumatoid nodules (described
above), most often around the elbows and fingers, can suggest the
diagnosis.
Abnormal antibodies can be found in the blood of people with
rheumatoid arthritis. An antibody called "rheumatoid factor" can be found in 80% of patients with rheumatoid arthritis. Patients who are felt to have rheumatoid arthritis and do not have positive rheumatoid factor testing are referred as having "seronegative rheumatoid arthritis." Citrulline antibody (also referred to as anticitrulline antibody, anticyclic citrullinated peptide antibody, and anti-CCP) is present in most people with rheumatoid arthritis. It is useful in the diagnosis of rheumatoid arthritis when evaluating
cases of unexplained joint inflammation. A test for citrulline antibodies is most helpful in looking for the cause of previously undiagnosed inflammatory arthritis when the traditional blood test for rheumatoid arthritis, rheumatoid factor, is not present. Citrulline antibodies have been felt to represent the earlier stages of rheumatoid arthritis in this setting. Another antibody called
the "antinuclear antibody" (ANA) is
also frequently found in people with rheumatoid arthritis.
A blood test called
the sedimentation rate (sed rate) is a measure of how fast red blood cells fall to the bottom
of a test tube. The sed rate is used as a crude measure of the inflammation of the joints. The sed rate is usually faster during disease flares and slower
during remissions. Another blood test that is used to measure the degree of
inflammation present in the body is the C-reactive protein. Blood testing may also reveal anemia, since anemia is common in rheumatoid arthritis, particularly because of the chronic inflammation.
The rheumatoid factor, ANA, sed rate, and
C-reactive protein tests can also be
abnormal in other systemic autoimmune and inflammatory conditions. Therefore, abnormalities
in these blood tests alone are not sufficient for a firm diagnosis of
rheumatoid arthritis.
Joint X-rays may be normal or only show swelling of soft tissues early in the disease. As the disease progresses, X-rays can show bony erosions typical of rheumatoid arthritis in the joints. Joint X-rays can also be helpful in monitoring the progression of disease and joint damage over time. Bone scanning, a procedure using a small amount of a radioactive substance, can also be used to demonstrate the inflamed joints. MRI scanning can also be used to demonstrate joint damage.
The American College of Rheumatology has developed a system for classifying rheumatoid arthritis that is primarily based upon the X-ray appearance of the joints. This system helps medical professionals classify the severity of your rheumatoid arthritis with respect to cartilage, ligaments, and bone.
Stage I
no damage seen on X-rays, although there may be signs of bone thinning
Stage II
on X-ray, evidence of bone thinning around a joint with or without slight bone damage
slight cartilage damage possible
joint mobility may be limited; no joint deformities observed
atrophy of adjacent muscle
abnormalities of soft tissue around joint possible
Stage III
on X-ray, evidence of cartilage and bone damage and bone thinning around the joint
joint deformity without permanent stiffening or fixation of the joint
extensive muscle atrophy
abnormalities of soft tissue around joint possible
Stage IV
on X-ray, evidence of cartilage and bone damage and osteoporosis around joint
joint deformity with permanent fixation of the joint (referred to as ankylosis)
extensive muscle atrophy
abnormalities of soft tissue around joint possible
Rheumatologists also classify the functional status of people with rheumatoid arthritis as follows:
Class I: completely able to perform usual activities of daily living
Class II: able to perform usual self-care and work activities but limited in activities outside of work (such as playing sports, household chores)
Class III: able to perform usual self-care activities but limited in work and other activities
Class IV: limited in ability to perform usual self-care, work, and other activities
The doctor may elect to perform an office procedure
called arthrocentesis. In this procedure, a sterile needle and syringe are used
to drain joint fluid out of the joint for study in the laboratory. Analysis of the joint fluid in the laboratory
can help to exclude other causes of arthritis,
such as
infection and gout. Arthrocentesis can also be helpful in relieving joint
swelling and pain. Occasionally, cortisone medications are injected into
the joint during the arthrocentesis in order to rapidly relieve joint
inflammation and further reduce symptoms.
Rheumatoid Arthritis - Early SymptomsQuestion: The symptoms of rheumatoid arthritis (RA) can vary greatly from patient to patient. What were your symptoms at the onset of your disease?
Gout is a condition that results from crystals of uric acid depositing in tissues of the body. Gout is a condition that can lead to abnormally elevated levels of uric acid in the
blood, recurring attacks of joint inflammation (arthritis), deposits of
hard lumps of uric acid in and around the joints, and decreased kidney
function and kidney stones.
The knee joint is composed of three compartments and ligaments which stabilize the joint. Causes of knee pain may include injury, degeneration, infrequently infection and rarely bone tumors. Although routine x-rays do not revel meniscus tears, they can be used to exclude other problems of the bones and tissues. The knee joint is the most commonly involved joint in rheumatic disease, as well as immune diseases that affect various tissues of the body.
Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly. They can sometimes be tender, painful or disfiguring. The treatment of swollen lymph nodes depends upon the cause.
Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
Lyme disease is a bacterial illness, which is spread by ticks when they bite the skin. Initially the disease affects the skin causing a reddish rash associated with flu-like symptoms. It takes weeks to months after the initial redness of the skin for its effects to spread throughout the body. Lyme disease can be treated with antibiotics. Lyme disease can be prevented by using tick avoidance techniques.
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous
system. When only the skin is involved, the condition is called discoid lupus.
When internal organs are involved, the condition is called systemic lupus
erythematosus (SLE).
Ankle pain is commonly due to a sprain or tendinitis. The severity of ankle sprains ranges from mild (which can resolve within 24 hours) to severe (which can require surgical repair). Tendinitis of the ankle can be caused by trauma or inflammation.
Sacroiliac joint (SI) dysfunction is a general term to reflect pain in the SI joints. Causes of SI joint pain include osteoarthritis, abnormal walking pattern, and disorders that can cause SI joint inflammation including gout, rheumatoid arthritis, psoriasis, and ankylosing spondylitis. Treatment includes oral medications, cortisone injections, and surgery.
Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of
arthritis including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout,
and pseudogout.
Raynaud's phenomenon is characterized by a pale-blue-red sequence of color changes of the digits, most commonly after exposure to cold. Occurring as a result of spasm of blood vessels, the cause is unknown. Symptoms of Raynaud's phenomenon depend on the severity, frequency, and duration of the blood vessel spasm. Treatments include protection of the digits, medications, and avoiding emotional stresses, smoking, cold temperature, and tools that vibrate the hands.
Celiac disease is a result of an immune reaction to gluten, a protein found in wheat or related grains and present in many foods that we eat. Celiac disease causes impaired absorption and digestion of nutrients through the small intestine. Signs and symptoms of celiac disease include malabsorbption (diarrhea, foul smelling gas, bloating, and increased amounts of fat in the stool) and malnutrition (weight loss, edema, anemia, bruising easily, neuropathy, and infertility). Treatment for celiac disease is a gluten free diet, and at times if necessary, medications
A Baker cyst, also called a popliteal cyst, is swelling caused by knee joint fluid protruding to the back of the knee (popliteal area of the knee). Not uncommon, baker cysts can be caused by virtually any type of joint swelling (arthritis). They are often resolved with removal of excess knee fluid in conjunction with cortisone injections.
Pleurisy, an inflammation of the lining around the lungs, is associated with sharp chest pain upon breathing in. Cough, chest tenderness, and shortness of breath are other symptoms associated with pleurisy. Pleurisy pain can be managed with pain medication and by external splinting of the chest wall.
Bursitis of the knee results when any of the three fluid-filled sacs (bursae) become inflamed due to injury or strain. Symptoms include pain, swelling, warmth, tenderness, and redness. Treatment of knee bursitis depends on whether infection is involved. If the knee bursa is not infected, knee bursitis may be treated with ice compresses, rest, and antiinflammatory and pain medications.
Cushing's syndrome, sometimes referred to as hypercortisolism, is a hormonal disorder caused by prolonged exposure to high levels of the hormone cortisol. Symptoms may include obesity, thinning arms and legs, a rounded face, and increased fat around the neck. Some causes of Cushing's syndrome is from taking glucocorticoid hormones such as prednisone for inflammatory diseases. Treatment for Cushing's syndrome depends on the cause.
Vasculitis is a general term for a group of uncommon diseases which feature inflammation of the blood vessels. Each form of vasculitis has its own characteristic pattern of symptoms. The diagnosis of vasculitis is definitively established after a biopsy of involved tissue demonstrates the pattern of blood vessel inflammation. Treatment is directed toward decreasing the inflammation of the arteries and improving the function of affected organs.
Dry eyes are caused by an imbalance in the tear-flow system of the eye, but also can be caused by the drying out of the tear film. This can be due to dry air created by air conditioning, heat, or other environmental conditions.
Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
Amyloidosis is a group of diseases resulting from abnormal deposition of certain proteins (amyloids) in various bodily areas. The amyloid proteins may either be deposited in one particular area of the body (localized amyloidosis) or they may be deposited throughout the body (systemic amyloidosis). There are three types of systemic amyloidosis: primary (AL), secondary (AA), and familial (ATTR). Primary amyloidosis is not associated with any other diseases and is considered a disease entity of its own. Secondary amyloidosis occurs as a result of another illness. Familial Mediterranean Fever is a form of familial (inherited) amyloidosis. Amyloidosis treatment involves treating the underlying illness and correcting organ failure.
Connective tissue disease is when the body's connective tissues come under attack, possibly becoming injured by inflammation. Inherited connective tissue diseases include Marfan syndrome and Ehlers-Danlos syndrome. Systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymositis, and dermatomyositis are examples of connective tissue diseases that have no known cause.
Osteopenia is a bone condition characterized by bone loss that is not as severe as in osteoporosis. Bone fracture is the typical symptom of osteopenia, though the condition may be present without symptoms. Treatment involves lifestyle modifications (quitting smoking, not drinking in excess) and ensuring an adequate intake of vitamin D and calcium.
Still's disease (Systemic-Onset Juvenile Rheumatoid Arthritis) is a disorder characterized by inflammation with high fever spikes, fatigue, salmon-colored rash and/or arthritis. Though there have been several theories regarding the cause(s) of Still's disease, the cause is not yet known. Many symptoms of Still's disease are often treatable with anti-inflammatory drugs.
Corticosteroid drugs such as prednisone and prednisolone are commonly used to treat asthma, allergic reactions, RA, and IBD. Steroids such as these do have serious drawbacks such as steroid withdrawal symptoms such as: fatigue, weakness, decreased appetite, weight loss, nausea, vomiting, abdominal pain, and diarrhea. Speak with your healthcare provider prior to tapering off steroid medications.
Chronic pain is pain (an unpleasant sense of discomfort) that persists or progresses over a long period of time. In contrast to acute pain that arises suddenly in response to a specific injury and is usually treatable, chronic pain persists over time and is often resistant to medical treatments.
Juvenile arthritis (juvenile rheumatoid arthritis or JRA) annually affects one child in every thousand. There are three types of JRA: pauciarticular (less than four joints affected), polyarticular (more than four joints affected), and systemic-onset (inflamed joints with high fevers and rash). Treatment of juvenile arthritis depends upon the type the child has and should focus on treating the symptoms that manifest.
A ganglion is a fluid-filled cyst that forms from the joint or tendon lining. Ganglia are most frequently found in the ankles and wrists and are usually painless. A ganglion often resolves on its own. Aspiration of the ganglion fluid or surgery may be necessary.
Relapsing polychondritis is an uncommon, chronic disorder of the cartilage that is characterized by recurrent episodes of inflammation of the cartilage of various tissues of the body. Tissues containing cartilage that can become inflamed include the ears, nose, joints, spine, and windpipe (trachea). Tissues that have a biochemical makeup similar to that of cartilage such as the eyes, heart, and blood vessels, can also be affected. Nonsteroidal antiinflammatory medications (NSAIDs) is used as treatment for mild cases of the disease. Steroid-related medications also are usually required.
Biologic rhythms, or biorhythms, are how our bodies respond to the regular phases of the sun, moon, and seasons. A medical chronobiologist studies how the "body clock" or biorhythms affect diseases and how the body clock responds to treatment of diseases and conditions at different times of the day.
Felty's syndrome is a complication of long-term rheumatoid arthritis. Felty's syndrome is defined by the presence of three conditions: rheumatoid arthritis, an enlarged spleen, and an abnormally low white blood count. Treatment of Felty's syndrome is not always required; however, treatment for patients with infections is available.
