What Is Rheumatoid Arthritis (RA)?
RA is a chronic autoimmune disease in which the body's immune system attacks joints and other tissues. RA can also cause complications in other areas of the body, including the organs.
What Are the Symptoms of Rheumatoid Arthritis?
The hallmark symptom of RA is morning stiffness of the joints that lasts at least 1 hour. RA usually first develops in the small joints of the hands, including the wrists, the knuckles, and the base of the fingers. It can also affect feet, ankles, knees, elbows, hips, and shoulders. Joint pain usually affects both sides of the body.
Who Has Rheumatoid Arthritis?
RA can occur at any age. But symptoms typically first appear in middle age (ages 30 to 50).
Women are more likely to develop RA than men.
How is Rheumatoid Arthritis Diagnosed?
RA can be difficult to diagnose when it's in its early stages. A doctor will base a diagnosis on a patient's medical history, physical exam, and the results of laboratory tests for specific antibodies.
How is Rheumatoid Arthritis Treated?
The treatment of RA involves medications and lifestyle changes (including exercise). The goals are to relieve pain, reduce inflammation, slow joint damage, and improve the patient's quality of life. Disease modifying anti-rheumatic drugs (DMARDs) and biological drugs are the main medications used for rheumatoid arthritis.
The American College of Rheumatology's (ACR) drug treatment guidelines for RA recommend:
Rheumatoid arthritis (RA) is a chronic disease in which various joints in the body are inflamed, leading to swelling, pain, stiffness, and the possible loss of function.
Rheumatoid arthritis (RA) is an autoimmune disease in which the body's immune system attacks joints and other tissues. The pattern of joints affected is usually on both sides, involves the hands and other joints, and is worse in the morning. RA is a systemic (body-wide) disease, involving other body organs, whereas osteoarthritis is limited to the joints. Both forms of arthritis can be crippling.
RA often develops in the following way:
The chronic inflammatory process associated with RA not only affects cartilage and bones but can also harm organs in other parts of the body.
Doctors do not know exactly what causes rheumatoid arthritis (RA). The condition is most likely triggered by a combination of factors including an abnormal autoimmune response, genetic susceptibility, and some environmental or biologic trigger such as a viral infection or hormonal changes.
RA is considered an autoimmune disease. Autoimmunity means "immunity against the self." In autoimmune disorders, the body's immune system mistakenly attacks and destroys healthy cells and tissue.
The Immune Response and Inflammatory Process
The immune system determines the body's responses to foreign substances (antigens) such as viruses and toxins. The immune response helps the body to fight infection and heal wounds and injuries. The inflammatory process is a byproduct of the immune response.
Two important components of the immune system that play a role in the inflammation associated with RA are B cells and T cells, both of which belong to a family of immune cells called lymphocytes. Lymphocytes are a type of white blood cell
A key feature of a healthy immune system is the ability to tell what is normal, or "self" and what is foreign and possibly harmful, or "non-self." If the T cell "sees" an antigen as "non-self," it will produce chemicals (cytokines) that cause B cells to multiply and release many immune proteins (antibodies). These antibodies circulate widely in the bloodstream, recognizing the foreign particles and triggering inflammation in order to rid the body of the invasion.
For reasons that are still not completely understood, both the T cells and the B cells become overactive in patients with RA and attack normal tissue as if it were foreign. This is why conditions like RA are referred to as "autoimmune" diseases: the body's immune system produces antibodies that attack it.
An antigen is a substance that can trigger an immune response. Normally, antigens are substances that are not present in the healthy body.
Genetic factors may play some role in RA either by increasing susceptibility to developing RA or by making it more severe. The main genetic marker identified with RA is HLA (human leukocyte antigen).
A number of HLA genetic forms are associated with rheumatoid arthritis. These genetic factors do not cause RA, but they may make the disease more severe once it has developed. Genetic variations in the HLA region may also predict how well a patient will respond to certain drugs used to treat rheumatoid arthritis.
Although many bacteria and viruses have been studied, no single organism has been identified as a trigger for RA. Some researchers think an infection may stimulate the immune system to start or prolong RA. Potential infectious triggers include E. coli, Mycoplasma, parvovirus B19, retroviruses, mycobacteria, certain bacteria seen with dental infections, and Epstein-Barr virus.
According to the U.S. Arthritis Foundation, rheumatoid arthritis (RA) affects about 1.5 million Americans.
Although RA can occur at any age from childhood to old age, onset usually begins between the ages of 30 to 50 years.
Women are more likely to develop RA than men.
Some people may inherit genes that make them more susceptible to developing RA, but a family history of RA does not appear to increase an individual's risk.
Long-term smoking is a very strong risk factor for RA, particularly in patients without a family history of the disease.
Severe periodontal disease and chronic infection of the gums is associated with RA and with developing antibodies to an antigen called cyclic citrullinated peptide (CCP). People with CCP antibodies have an increased risk for developing a more severe form of RA.
The course of rheumatoid arthritis (RA) differs from person to person. For some patients, the disease becomes less aggressive over time and symptoms may improve. Other people develop a more severe form of the disease, which can lead to serious complications that affect not only the joints but other areas of the body including organs. Fortunately, for many patients newer treatments are helping to slow the progression of the disease and prevent severe disability.
Many complications of RA are the result of chronic inflammation.
Joint Deterioration and Pain
Affected joints can become damaged and deformed with ongoing active disease. Some patients find it difficult or impossible to perform even ordinary daily tasks. In addition to pain, patients may also experience muscle weakness.
This condition affects the nerves, most often those in the hands and feet. It can result in tingling, numbness, or burning.
People with RA may develop anemia, which involves a reduction in the number of red blood cells. Anemia can cause symptoms such as fatigue and shortness of breath.
Scleritis and episcleritis are inflammations of the blood vessels in the eye that can result in corneal damage. Symptoms include redness of the eye and a gritty sensation. Some people with rheumatoid arthritis also have Sjögren syndrome, an autoimmune disorder in which the glands that produce tears and saliva are destroyed. This causes dry mouth and dry eyes.
Patients with RA have a higher risk for infections, both because of the disease itself and the immune-suppressing drugs used to treat it. Before starting treatment with a disease-modifying or biologic drug, patients should receive age-appropriate vaccinations for pneumococcus, influenza, hepatitis B, human papillomavirus, and varicella zoster virus. While taking certain medications for RA, live vaccines are contraindicated. Thus it makes sense to give those vaccines prior to initiating these medications if possible.
Skin problems are common, particularly on the fingers and under the nails. Some patients develop severe skin complications that include rash, ulcers, blisters (which may bleed in some cases), lumps or nodules under the skin, and other problems. In general, severe skin involvement reflects a more serious form of RA.
Osteoporosis, loss of bone density, is more common than average in postmenopausal women with RA. The hip is particularly affected. The risk for osteoporosis also appears to be higher than average in men with RA who are over 60 years old. Corticosteroids (also called steroids) used to treat RA may contribute to osteoporosis.
Patients with RA are susceptible to chronic lung diseases, including interstitial fibrosis, pulmonary hypertension, and other problems. Both RA itself and some of the drugs used to treat it may cause this damage.
Vasculitis involves inflammation in small blood vessels and can affect many organs in the body. Manifestations of vasculitis include mouth ulcers, nerve disorders, rapid worsening of the lungs, inflammation of coronary arteries, and inflammation of the arteries supplying blood to the intestines.
Heart and Circulatory Diseases
Patients with RA have an increased risk for heart and circulatory conditions including coronary artery disease, heart attack, atrial fibrillation, and stroke. They may also face higher risks for venous thromboembolism (VTE), a condition that includes deep vein thrombosis (formation of blood clots in the veins) and pulmonary embolism (clots in the arteries of the lungs).
Lymphoma and Other Cancers
Patients with RA are more likely than healthy patients to develop non-Hodgkin's lymphoma. RA's chronic inflammatory process may play a role in the development of this cancer. Anti-TNF drugs used for RA treatment may also possibly increase the risk for lymphoma (particularly in children and adolescents) as well as leukemia and other malignancies.
People with RA have a higher risk for developing periodontal disease, which damages the gum and bone around the teeth. (Conversely, severe periodontal disease can also be a risk factor for developing RA.)
Kidney and Liver Problems
Although RA only rarely involves the kidney, some of the drugs used to treat the disease can damage kidneys and the liver.
RA is a painful and frustrating condition. Patients often struggle with depression and anxiety. The stress of dealing with a chronic illness can worsen pain.
Women with RA have an increased risk for premature delivery. They are also more likely than healthy women to develop high blood pressure during the last trimester of pregnancy. For many women with RA, the disease goes into remission during pregnancy but the condition recurs and symptoms can increase in severity after giving birth.
Rheumatoid arthritis (RA) symptoms usually develop gradually over the course of weeks or even months. However, rapid onset with more severe symptoms may also occur.
The hallmark symptom of RA is morning stiffness that lasts for at least an hour and sometimes up to several hours. (Stiffness from osteoarthritis, in contrast, usually clears up within half an hour.) Joints may also feel very stiff if not used for long periods of time throughout the day. Warmth or activity can help relieve the stiffness.
Swelling and Pain
Swelling and pain in the joints must occur for at least 6 weeks before a diagnosis of RA is considered. The inflamed joints are usually swollen and often feel warm and "boggy" (spongy) when touched. The pain often occurs on both sides of the body (symmetrically) but may be more severe on one side of the body, depending on which hand the person uses more often.
Specific Joints Affected
RA usually first develops in the small joints of the hands, including the wrists, the knuckles, and the base of the fingers. It can also affect feet, ankles, knees, elbows, hips, and shoulders. Many joints may eventually be involved, including those in the upper part of the cervical spine, temporomandibular joint (jaw), and even joints between very small bones in the inner ear.
In some patients with RA, inflammation of small blood vessels can cause nodules, or lumps, under the skin. They are about the size of a pea or slightly larger, and are often located near the elbow, although they can show up anywhere. Nodules can occur throughout the course of the disease, although they are usually a sign of more severe disease. Rarely, nodules may become sore and infected, particularly if they are in locations where stress occurs, such as the ankles.
Fluid may accumulate, particularly in the ankles. In some cases, the joint sac behind the knee accumulates fluid and forms what is known as a Baker's cyst. This cyst feels like a tumor and sometimes extends down the back of the calf causing pain. Baker's cysts can also develop in people who do not have RA.
The inflammation associated with RA may also cause general "flu-like" symptoms such as fatigue, loss of appetite, and low-grade fever.
Symptoms in Children
In children, juvenile rheumatoid arthritis, also known as Still's disease, is usually preceded by high fever and shaking chills along with pain and swelling in many joints. A pink skin rash may be present.
Rheumatoid arthritis (RA) can be difficult to diagnose. Many other conditions resemble RA. Its symptoms can develop insidiously. Blood tests and x-rays may show normal results for months after the onset of joint pain.
Specific findings or presentation more likely to suggest the diagnosis of RA include morning stiffness, involvement of three joints at the same time, involvement of both sides of the body, subcutaneous (under the skin) nodules, positive test for rheumatoid factor antibodies, and changes in x-rays.
Various blood tests may be used to help diagnose RA, determine its severity, and detect complications of the disease.
In about 80% of cases of RA, blood tests reveal antibodies in the blood known as rheumatoid factor (RF). RF can also show up in blood tests of people with other autoimmune diseases. However, when it appears with clinical signs and symptoms of rheumatoid arthritis, it is a strong indicator of RA. A negative test does not necessarily rule out RA.
A cyclic citrullinated peptide (CCP) antibody test is often ordered along with a rheumatoid factor test. If people with signs and symptoms of RA test positive for both CCP antibody and rheumatoid factor, it is an indicator that not only do they have RA but they may also develop a more severe or rapidly progressing form of the disease. A positive test for CCP but negative test for RA along with clinical signs and symptoms may suggest early-stage RA or an increased likelihood of developing RA in the future.
Erythrocyte Sedimentation Rate
An erythrocyte sedimentation rate (ESR or sed rate) is a measure of inflammation. The higher the sed rate, the greater the inflammation. Because the sed rate can be high in many conditions ranging from infection to inflammation to tumors, the ESR test is used not for diagnosis but to help determine how active the RA is.
A test for C-reactive protein (CRP) may be ordered along with an ESR test. High levels of C-reactive protein (CRP) are also indicators of active inflammation. Like the ESR, a high CRP result does not indicate the source or cause of the inflammation.
Tests for Anemia
Anemia, a reduction in red blood cells, is a common complication of rheumatoid arthritis. Blood tests determine the amount of red blood cells (hemoglobin and hematocrit) and iron (soluble transferrin receptor and serum ferritin) in the blood.
Synovial Fluid Test
A synovial fluid analysis may help in differentiating RA from osteoarthritis. To perform this test, the doctor inserts a sterile needle into the joint and withdraws the synovial fluid into a syringe attached to the needle. The fluid is sent to a laboratory for analysis.
X-rays are generally not helpful for showing joint damage in early RA because they cannot show images of soft tissue. However, x-rays do show the progression of joint damage over time. The doctor may also order other imaging tests, such as ultrasound, or magnetic resonance imaging (MRI). Dual energy x-ray absorptiometry (DXA or DEXA scans), also called bone densitometry, may be used to check for signs of bone density loss associated with osteoporosis.
Conditions with Similar Symptoms
Symptoms of RA can resemble things as harmless as a bad mattress or as serious as cancer. Several rare genetic diseases attack the joints. Physical injuries, infections, and poor circulation are among the many problems that can cause aches and pains. Many conditions start with symptoms of joint aches and pains. A few that in particular may be confused with RA arthritis include:
Osteoarthritis is the most common form of arthritis, but it differs from RA in several important respects:
Gout also causes swelling and severe pain in a joint. It most commonly starts in one joint. It is sometimes difficult to distinguish chronic gout in older people from rheumatoid arthritis, since gout in this population can occur in a number of joints. A proper diagnosis can be made with a detailed medical history, blood tests, and finding uric acid crystals in the affected joint.
The treatment of rheumatoid arthritis (RA) involves medications and lifestyle changes.
General Guidelines for Drug Treatments
Many drugs are used for managing the pain and slowing the progression of RA, but none completely cure the disease. The goals of drug treatment for RA are to reduce disease activity and achieve remission, which includes:
Drug Categories Used for Rheumatoid Arthritis
The drug classes used for RA include:
In the past, before current drugs became available, the question of how early and how aggressively to treat RA was the subject of great debate. Some patients with early RA go into remission and remain in remission for the length of their lives even in the absence of treatment. Other patients go on to develop active, sometimes severe RA.
Today, current practice recommends treating the disease aggressively while it is in its early stages to help prevent it from reaching a more severe and chronic state. Studies have found less joint damage in patients with early, aggressive treatment, particularly with the use of DMARDs and TNF modifiers in combination with methotrexate.
Patients in early stages of RA with moderate symptoms are usually started on a single drug such as methotrexate. Patients with more advanced disease or those who have not been helped by single drug therapy often benefit from a combination of drugs, including other DMARDs, a biologic TNF blocker, or another type of biologic drug.
There is no one-size-fits-all drug treatment approach for rheumatoid arthritis. Your doctor will make a decision on which drug or drugs to prescribe based on:
[For more specific information on drugs, see Medications section of this report.]
Disease-Modifying Anti-Rheumatic Drugs (DMARDs)
Disease-modifying anti-rheumatic drugs (DMARDs) are the standard treatments for rheumatoid arthritis (RA). They are used either alone or in combination with newer biologic DMARDs.
DMARDs do not have any common properties other than their ability to slow down the progression of rheumatoid arthritis. Many were used for other diseases and were found accidentally to help RA. DMARDs include:
Unfortunately, most patient experience a decrease in efficacy of a DMARD after extenderd periods of therapy. Combining DMARDs with each other or with other types of drugs offers the best approach for many patients.
All DMARDs may produce stomach and intestinal side effects, and, over the long term, each poses some risk for rare but serious reactions. (In some cases, however, they may be less harmful than long-term NSAID treatment.)
Methotrexate (Rheumatrex, Trexall, Otrexup, generic) acts as an anti-inflammatory drug and is generally the most frequently used DMARD, particularly for severe disease. Methotrexate starts working within 3 to 6 weeks, but its full effect may not occur until after 12 weeks of treatment.
Even this drug loses effectiveness, however, when used alone. For this reason, it is often used in combination with other DMARDs such as hydroxychloroquine, sulfasalazine (Triple Therapy). It may also be combined with various biological response modifier drugs, especially for treatment of patients with early aggressive arthritis. The combination appears to work better than single drug therapy.
Some patients have to stop taking methotrexate because of its side effects. They include nausea and vomiting, rash, mild hair loss, headache, mouth sores, and muscle aches. Methotrexate reduces levels of folic acid (folate) in the body, which can lead to some of these side effects. Doctors may prescribe folic acid supplements to prevent side effects. However, some research suggests that folic acid may interfere with methotrexate's effectiveness.
Methotrexate is usually given as pills. Patients who need higher doses can take it as an injection. Methotrexate has fewer serious toxic effects than many DMARDs. Although these severe reactions are rare, they may include:
Leflunomide (Arava, generic) blocks autoimmune antibodies and reduces inflammation. It also may inhibit metalloproteinases (MMP), which are involved in cartilage destruction. Leflunomide takes several weeks before improving joint pain or swelling. Full benefits may not occur until 6 to 12 weeks of treatment.
Leflunomide may be given alone or in combination with other DMARDs such as methotrexate. (This combination poses a risk for liver toxicity and requires monitoring.)
Side effects are similar to those of methotrexate, including nausea, diarrhea, hair loss, and rash. Potentially serious side effects include infections and severe liver injury. Everyone taking leflunomide should be monitored regularly, including blood tests for liver function, and anyone with liver problems should not take this drug. Leflunomide should not be taken by patients with active bacterial infections, active herpes-zoster viral infection, active or latent tuberculosis, or acute or chronic hepatitis B or C. As with methotrexate, the drug increases the risk for birth defects and should not be taken by pregnant women.
Hydroxychloroquine (Plaquenil, generic) was originally used for preventing malaria and is now also used for mild, slowly progressive rheumatoid arthritis. Hydroxychloroquine starts to improve symptoms within 1 - 2 months, but it may take up to 6 months to achieve full benefit. Hydroxychloroquine usually causes fewer side effects than other DMARDs but it does not appear to slow disease progression. The most common side effects are nausea and diarrhea, which typically improve over time or when the drug is taken with food. Less common side effects include skin rash or bleaching or thinning of hair.
This drug used to be associated with eye and vision problems, but with current lower doses this side effect is rare. If vision problems occur, it is usually with people taking very high doses, those with kidney disease, or those over 60 years of age. Still, patients should have an eye exam (including retinal examination) within the first year of treatment. Patients on plaquenil should have frequent eye exams. Patients should notify their doctors if they experience any sudden changes in vision.
Sulfasalazine (Azulfidine, generic) works best when the disease is confined to the joints. Symptom relief occurs within 1 to 3 months.
Side effects are common, particularly stomach and intestinal distress, which usually occur early in the course of treatment. (However, serious gastrointestinal side effects, such as stomach ulcers, occur less frequently with sulfasalazine than with NSAIDs.) A coated-tablet form may help reduce side effects. Other side effects include skin rash and headache. Sulfasalazine increases sensitivity to sunlight. Be sure to wear sunscreen (SPF 15 or higher) while taking this drug. People with intestinal or urinary obstructions or who have allergies to sulfa drugs or salicylates should not take sulfasalazine.
Minocycline (Minocin, generic) is a tetracycline antibiotic that is generally reserved for patients with mild RA. It can take 2 to 3 months before symptoms begin to improve and up to a year for full benefit. Side effects include upset stomach, dizziness, and skin rash. Long-term use of minocycline can cause changes in skin color, but this side effect usually disappears once the medication is stopped. Minocycline can cause yeast infections in women. It should not be used by women who are pregnant or planning on becoming pregnant. Minocycline increases sensitivity to sunlight and patients should be sure to wear sunscreen. In rare cases, minocycline can affect the kidneys and liver.
Gold used to be a time-honored DMARD for RA but its use has decreased with the development of newer DMARDs and biologic drugs. Gold is usually administered in an injected form because the oral form, auranofin (Ridaura, generic), is much less effective. There are two injectable forms of gold: Gold sodium thiomalate (Myochrysine, generic) and aurothioglucose (Solganal, generic). It can take 3 to 6 months before injections have an effect on RA symptoms. Gold injections can cause a number of side effects including mouth sores and skin rash and in rare cases more serious problems such as kidney damage.
Azathioprine (Imuran, generic) suppresses immune system activity. It takes 6 to 8 weeks for early symptom improvement and up to 12 weeks for full benefit. Azathioprine can cause serious problems with the gastrointestinal tract including nausea and vomiting, often accompanied by stomach pain and diarrhea. Azathioprine can also cause problems with liver function and pancreas gland inflammation, and can reduce white blood cell count.
Cyclosporine. Like azathioprine, cyclosporine (Sandimmune, Neoral, generic) is an immunosuppressant. It is used for people with RA who have not responded to other drugs. It can take a week before symptoms improve and up to 3 months for full benefit. The most serious and common side effects of cyclosporine are high blood pressure and kidney function problems. While kidney function usually improves once the drug is stopped, mild-to-moderate high blood pressure may continue. Swelling of the gums is also common. Patients should practice good dental hygiene, including regular brushing and flossing.
Small Molecule DMARDs
Tofacitinib (Xeljanz) is a newer DMARD. Tofacitinib is the first in a new class of drugs. It works by blocking "Janus kinase" molecules involved in joint inflammation. There is hope that DMARD might be an alternative to biologic DMARDs, and a new option for patients with moderate-to-severe RA who have not been helped by methotrexate. Tofacitinib, which is taken as a pill, can be used alone or in combination with methotrexate. Tofacitinib may increase the risk for serious infections. Because it is new a drug, long-term side effects are still unknown. Several newer drugs that work in a similar same way are being studied.These include Baricitinib, Decernotinib, Fostamatinib, and Filgotinib.
Biologic Response Modifiers (Biologic DMARDs)
Biologic response modifiers are drugs made from living cells. These drugs target specific components of the immune system that contribute to the joint inflammation and damage that are part of the RA disease process.
Biologic DMARDs are generally used to treat moderate-to-severe RA. Some of these drugs are used as first-line treatments for RA. Others are used for patients who have not responded to DMARDs or other types of treatment. Depending on the specific drug, they may be used alone or in combination with the DMARD methotrexate. However, biologic response modifiers are not used in combination with each other, as this can lead to serious infections.
As with other RA drugs, these drugs do not cure the disease but can help slow progression and joint damage.
Most biologic DMARDs are anti-tumor necrosis factor (anti-TNF) drugs. They block TNF, which is a cytokine involved in the inflammatory process. Anti-TNF drugs approved for treatment of RA are:
Other Biologic DMARDs
Other biologic DMARDs approved for RA treatment are:
Side Effects and Complications
Etanercept, adalimumab, anakinra, golimumab, certolizumab, and abatacept come in pre-filled syringes and are given by injection under the skin (subcutaneous injection). This may cause pain at the injection site. To prevent injection reactions, patients are sometimes pretreated with betamethasone, a corticosteroid drug, but some research suggests that the steroid does little good.
Infliximab, tocilizumab, abatacept, and rituximab are given by intravenous infusion in a doctor's office. Common infusion reactions include headache, nausea, and flu-like symptoms. Because biologic response modifiers affect the immune system, patients who take these drugs have an increased risk for infections.
Biologic DMARDs should not be taken by patients with active bacterial infections, active herpes-zoster (shingles) viral infection, active or latent tuberculosis, or active or chronic hepatitis B. Anti TNF drugs should be avoided in patients with acute hepatitis C infection or with chronic hepatitis C infection (treated or untreated) with significant liver injury. In addition, anti-TNF drugs should not be given to patients with a history of heart failure, a history of lymphoma, or who have multiple sclerosis or other demyelinating disorders.
Other risks associated with these drugs include:
Corticosteroids, also called glucocorticoids or steroids, are powerful drugs that work rapidly to reduce inflammation. Steroids mimic the action of cortisol, a hormone produced naturally in the adrenal gland. For treatment of rheumatoid arthritis, corticosteroids may be given orally by mouth or by injection into a joint.
Oral corticosteroids, such as prednisolone and prednisone (Deltasone, Orasone, generic) are often used in combination with DMARDs. Corticosteroids are often used early in the treatment of active RA since they act rapidly. As the DMARDS begin to reduce activity of RA, the corticosteroids are tapered off and stopped. They may also be used during an acute flare-up.
Side Effects of Oral Corticosteroids
Serious side effects are associated with long-term use of oral steroids. Doctors recommend taking as low a dose as possible. (However, side effects can still occur with daily use of low doses.)
Osteoporosis is a common and particularly severe long-term side effect of prolonged steroid use. Other adverse effects include weight gain, fat deposits, fluid retention and swelling, increased appetite and weight gain, bruising, acne, high blood pressure, cataracts, glaucoma, diabetes, susceptibility to infections, muscle wasting, menstrual irregularities, and mood swings.
Withdrawal from Long-Term Use of Oral Corticosteroids
Long-term use of oral steroid medications suppresses secretion of natural steroid hormones by the adrenal glands. After withdrawal from these drugs, this adrenal suppression persists and it can take the body a while (sometimes up to a year) to regain its ability to produce natural steroids again.
No one should stop taking any steroids without consulting a doctor first, and if steroids are withdrawn, regular follow-up monitoring is necessary. Patients should discuss with their doctor measures for preventing adrenal insufficiency during withdrawal, particularly during stressful times, when the risk increases.
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
Two-thirds of people with RA rank pain as their primary reason for seeking professional help. The most common pain relievers for RA are nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs block prostaglandins, the substances that widen blood vessels and cause inflammation and pain. There are dozens of NSAIDs:
Studies suggest that the best times for taking an NSAID may be after the evening meal and then again on awakening. RA symptoms increase gradually during the night, reaching their greatest severity at the time of awakening. Taking NSAIDs with food can reduce stomach discomfort, although it may slow the pain-relieving effect.
Long-term, regular use of NSAIDs (with the exception of aspirin) can increase the risk for heart attack, especially for people who have a heart condition. Long-term use of NSAIDs also increases the risk of ulcers and gastrointestinal bleeding. This risk can be reduced by taking antacid medication such as omeprazole (Prilosec, generic) along with the NSAID. To reduce the risks associated with NSAIDs, take the lowest dose possible for pain relief.
Other possible side effects of NSAIDs may include:
COX-2 Inhibitors (Coxibs)
Coxibs inhibit an inflammation-promoting enzyme called COX-2. This drug class was initially thought to provide benefits equal to NSAIDs, but cause less gastrointestinal distress. However, following numerous reports of heart problems, skin rashes, and other adverse effects, the FDA re-evaluated the risks and benefits of COX-2 inhibitors. Several coxib drugs were removed from the United States market. Celecoxib (Celebrex) is still available, but patients should ask their doctors whether the drug is appropriate and safe for them. Like all NSAIDs, celecoxib has a "black box" warning on its prescribing label that it may increase the risk for heart attack, stroke, and serious stomach problems.
Some people with RA benefit from joint surgery. Surgery can help relieve joint pain, correct deformities, and modestly improve joint function. There are several types of joint surgery techniques.
Synovectomy is removal of the joint lining (synovium). It is used to remove inflamed tissue that causes pain. Synovectomy can help reduce swelling and slow the progression of joint damage.
The procedure may be performed on joints in the knees, elbows, wrists, fingers, or hips. Synovectomy may be performed as open surgery (arthrotomy) or arthroscopically (arthroscopic synovectomy).
Arthroscopy is a surgical procedure that uses a small lighted tube with a camera (called an arthroscope), which is inserted the joint. A fiber-optic cable attached to the arthroscope allows the surgeon to view the inside of the joint on a monitor.
Arthroscopy can be used to perform different procedures including synovectomy. It may also be used to clean out bone and cartilage fragments (a process called debridement) that cause pain and inflammation.
Joint Replacement (Arthroplasty)
Eventually, even after these procedures, RA may progress to the point that normal functioning is impossible. In such cases, artificial (prosthetic) replacement joint implants may be considered for shoulders, knees, hips, ankles, wrists and hands, or other joints.
Joint replacement (arthroplasty) is usually reserved for people over age 50 or those whose joint damage is rapidly progressing. The joint replacement typically lasts for 20 years or more.
Joint Fusion (Arthrodesis)
If the affected joint cannot be replaced, surgeons can perform a procedure called arthrodesis that eliminates pain by fusing the bones together. However, fusing the bones makes movement of the joint impossible. Bone fusion is most often done in the spine and in the small joints of the hands (wrists, fingers) and feet (ankles, toes).
Lifestyle changes can help patients deal with the physical and emotional aspects of living with rheumatoid arthritis (RA).
It is important for patients with RA to maintain a balance between rest (which will reduce inflammation) and moderate exercise (which will relieve stiffness and weakness). Studies have suggested that even as little as 3 hours of physical therapy over 6 weeks can help people with RA, and that these benefits are sustained.
The goal of exercise is to:
In general, doctors recommend the following approaches:
A common-sense approach to exercise is the best guide:
Many patients with RA try dietary approaches, such as fasting, vegan diets, or eliminating specific foods that seem to worsen RA symptoms. There is little scientific evidence to support these approaches but some patients report that they are helpful.
In recent years, a number of studies have suggested that the omega-3 fatty acids contained in fish oil may have anti-inflammatory properties useful for RA joint pain relief. The best source of fish oil is through increased consumption of fatty fish such as salmon, mackerel, and herring. Fish oil supplements are another option, but they may interact with certain medications. If you are thinking of trying fish oil supplements, talk to your doctor first.
Pain and Stress Management
Patients can learn strategies to cope with the stress and frustration of living with chronic pain. Relaxation and stress management techniques such as guided imagery, breathing exercises, hypnosis, or biofeedback can be helpful.
Although there is no definitive evidence to support their efficacy, some patients report relief with modalities such as acupuncture, massage, and mineral baths.
There are many different types of assisted devices that can help make life easier in the home. Kitchen gadgets, such as jar openers, can assist with gripping and grabbing. Door-knob extenders and key turners are helpful for patients who have trouble turning their wrists. Bathrooms can be fitted with shower benches, grip bars, and raised toilet seats. An occupational therapist can advise you on choosing the right kinds of assistive devices.
Miscellaneous Supportive Treatments
Various ointments, including Ben Gay and capsaicin (a cream that use the active ingredient in chili peppers), may help soothe painful joints.
Orthotic devices are specialized braces and splints that support and help align joints. Many such devices made from a variety of light materials are available and can be very helpful when worn properly.
Herbal remedies used for RA include Boswellia, equisetum arvense (horsetail), devil's claw, borage seed oil, and many others. To date, no evidence supports their efficacy.
Researchers are currently conducting studies to determine if supplements extracted from the turmeric spice can help prevent joint inflammation. The Chinese medicine herb Tripterygium wilfordii Hook F (TwHF) is also being investigated for its anti-inflammatory properties.
Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.
Living and Coping with Rheumatoid Arthritis
Like all chronic illnesses, RA poses many frustrations and challenges -- physical, emotional, financial, and otherwise. It affects all dimensions of a person's life including work, family, and relationships. In addition, many patients with RA are diagnosed while in their prime adult years, when they may have responsibilities for taking care of children or elderly parents.
It is absolutely normal and natural for patients to feel overwhelmed, especially after first receiving a diagnosis. It is important to know that the newer medications, when started early for RA, have markedly improved the long-term outlook for RA. Specialists called rheumatologists are most familiar with these medications and treatments for RA.
The following are some tips for living and coping with RA:
