How is rheumatoid arthritis
treated?
Nondrug approaches include the
following:
- Physical therapy helps preserve and
improve range of motion, increase muscle
strength, and reduce pain.
- Hydrotherapy involves exercising or
relaxing in warm water. Being in water reduces
the weight on your joints. The warmth relaxes
your muscles and helps relieve pain.
- Relaxation therapy teaches techniques for
releasing muscle tension, which helps relieve
pain.
- Both
heat and cold treatments can relieve pain and
reduce inflammation. Some peoples pain responds
better to heat and other to cold. Heat can be
applied by ultrasound, microwaves, warm wax, or
moist compresses. Most of these are done in the
medical office, although moist compresses can be
applied at home. Cold can be applied with ice
packs at home.
- Occupational therapy teaches you ways to
use your body efficiently to reduce stress on
your joints. It also can help you learn to
decrease tension on the joints through the use
of specially designed splints. Your occupational
therapist can help you develop strategies for
coping with daily life by adapting to your
environment and using different assistive
devices.
- Prosorba column: This is not a drug but a
medical device. It filters antibodies linked to
rheumatoid arthritis out of the blood. This
procedure is available only in some medical
centers and generally is used only for very
severe rheumatoid arthritis.
- In
some cases, reconstructive surgery and/or joint
replacement operations provide the best
outcome.
There is no known cure for
rheumatoid arthritis. To date, the goal of
treatment in rheumatoid arthritis is to reduce
joint inflammation and pain, maximize joint
function, and prevent joint destruction and
deformity. Early medical intervention has been
shown to be important in improving outcomes.
Aggressive management can improve function, stop
damage to joints as seen on x-rays, and prevent
work disability. Optimal treatment for the
disease involves a combination of medications,
rest, joint strengthening exercises, joint
protection, and patient (and family) education.
Treatment is customized according to many
factors such as disease activity, types of
joints involved, general health, age, and
patient occupation. Treatment is most successful
when there is close cooperation between the
doctor, patient, and family
members.
Two classes of medications
are used in treating rheumatoid arthritis:
fast-acting "first-line drugs" and slow-acting
"second-line drugs" (also referred to as
Disease-Modifying Antirheumatic Drugs or
DMARDs). The first-line drugs, such as aspirin
and cortisone (corticosteroids), are used to
reduce pain and inflammation. The slow-acting
second-line drugs, such as gold,
hydroxychloroquin(Plaquenil) promote disease
remission and prevent progressive joint
destruction, but they are not anti-inflammatory
agents.
The degree of
destructiveness of rheumatoid arthritis varies
from patient to patient. Patients with uncommon,
less destructive forms of the disease or disease
that has quieted after years of activity
("burned out" rheumatoid arthritis) can be
managed with rest, pain and anti-inflammatory
medications alone. In general, however, patients
improve function and minimize disability and
joint destruction when treated earlier with
second-line drugs (disease-modifying
antirheumatic drugs), even within months of the
diagnosis. Most patients require more aggressive
second-line drugs, such as methotrexate, in
addition to anti-inflammatory agents. Sometimes
these second-line drugs are used in combination.
In some patients with severe joint deformity,
surgery may be necessary.
"First-line" drugs
Acetylsalicylate
(Aspirin), naproxen (Naprosyn), ibuprofen
(Advil, Medipren, Motrin), and etodolac (Lodine)
are examples of nonsteroidal anti-inflammatory
drugs (NSAIDs). NSAIDs are medications that can
reduce tissue inflammation, pain and swelling.
NSAIDs are not cortisone. Aspirin, in doses
higher than that used in treating headaches and
fever, is an effective antiinflammatory
medication for rheumatoid arthritis. Aspirin has
been used for joint problems since the ancient
Egyptian era. The newer NSAIDs are just as
effective as aspirin in reducing inflammation
and pain, and require fewer dosages per day.
Patients' responses to different NSAID
medications vary. Therefore, it is not unusual
for a doctor to try several NSAID drugs in order
to identify the most effective agent with the
fewest side effects.
The most common side effects
of aspirin and other NSAIDs include stomach
upset, ticlekey=1908">sucralfate (Carafate),
proton-pump inhibitors (Prevacid, and others),
and misoprostol (Cytotec).
Corticosteroid medications can be given
orally or injected directly into tissues and
joints. They are more potent than NSAIDs in
reducing inflammation, and in restoring joint
mobility and function. Corticosteroids are
useful for short periods during severe flares of
disease activity, or when the disease is not
responding to NSAIDs. However, corticosteroids
can have serious side effects, especially when
given in high doses for long periods of time.
These side effects include weight gain, facial
puffiness, thinning of the skin and bone, easy
bruising, cataracts, risk of infection, muscle
wasting, and destruction of large joints, such
as the hips. Corticosteroids also carry some
increased risk of contracting infections. These
side effects can be partially avoided by
gradually tapering the doses of corticosteroids
as the patient achieves improvement of the
disease. Abruptly discontinuing corticosteroids
can lead to flares of the disease or other
symptoms of corticosteroid withdrawal, and is
discouraged. Thinning of the bones due to
osteoporosis may be prevented by calcium and
vitamin D supplements. For further information
on corticosteroids, please read the article on
prednisone.
"Second-line" or "slow-acting"
drugs
(Disease-modifying anti-rheumatic drugs
or DMARDs)
While "first-line"
medications (NSAIDs and corticosteroids) can
relieve joint inflammation and pain, they do not
necessarily prevent joint destruction or
deformity. Rheumatoid arthritis requires
medications other than NSAIDs and
corticosteroids to stop progressive damage to
cartilage, bone, and adjacent soft tissues. The
medications needed for ideal management of the
disease are also referred to as
Disease-modifying Anti-rheumatic Drugs or
DMARDs. They come in a variety of forms and are
listed below. These "second-line" or
"slow-acting" medicines may take weeks to months
to become effective. They are used for long
periods of time, even years, at varying doses.
If effective, DMARDs can promote remission,
thereby retarding the progression of joint
destruction and deformity. Sometimes a number of
second-line medications are used together as
combination therapy. As with the first-line
medications, the doctor may need to use
different second-line medications before
treatment is optimal.
Recent research
suggests that patients who respond to a DMARD
with control of the rheumatoid disease may
actually decrease the known risk (small, but
real) of lymphoma that exists from simply having
rheumatoid arthritis.
Hydroxychloroquine (Plaquenil) is related
to quinine, and is also used in the treatment of
malaria. It is used over long periods for the
treatment of rheumatoid arthritis. Possible side
effects include upset stomach, skin rashes,
muscle weakness, and vision changes. Even though
vision changes are rare, patients taking
Plaquenil should be monitored by an eye doctor
(ophthalmologist).
Sulfasalazine
(Azulfidine) is an oral medication traditionally
used in the treatment of mild to moderately
severe inflammatory bowel diseases, such as
ulcerative colitis and Crohn's colitis.
Azulfidine is used to treat rheumatoid arthritis
in combination with antiinflammatory
medications. Azulfidine is generally well
tolerated. Common side effects include rash and
upset stomach. Because Azulfidine is made up of
sulfa and salicylate compounds, it should be
avoided by patients with known sulfa
allergies.
Methotrexate has gained popularity among
doctors as an initial second-line drug because
of both its effectiveness and relatively
infrequent side effects. It also has an
advantage in dose flexibility (dosages can be
adjusted according to needs). Methotrexate is an
immune suppression drug. It can affect the bone
marrow and the liver, even rarely causing
cirrhosis. All patients taking methotrexate
require regular blood test monitoring of blood
counts and liver function blood
tests.
Gold salts have been
used to treat rheumatoid arthritis throughout
most of the past century. Gold thioglucose
(Solganal) and gold thiomalate (Myochrysine) are
given by injection, initially on a weekly basis
for months to years. Oral gold, auranofin
(Ridaura) was introduced in the 1980's. Side
effects of gold (oral and injectable) include
skin rash, mouth sores, kidney damage with
leakage of protein in the urine, and bone marrow
damage with anemia and low white cell count.
Patients receiving gold treatment are regularly
monitored with blood and urine tests. Oral gold
can cause diarrhea. These gold drugs have lost
such favor that many companies no longer
manufacture them.
D-penicillamine
(Depen, Cuprimine) can be helpful in selected
patients with progressive forms of rheumatoid
arthritis. Side effects are similar to those of
gold. They include fever, chills, mouth sores, a
metallic taste in the mouth, skin rash, kidney
and bone marrow damage, stomach upset, and easy
bruising. Patients on this medication require
routine blood and urine tests. D-penicillamine
can rarely cause symptoms of other autoimmune
diseases.
Immunosuppressive
medicines are powerful medications that suppress
the body's immune system. A number of
immunosuppressive drugs are used to treat
rheumatoid arthritis. They include methotrexate
(Rheumatrex, Trexall) as described above,
azathioprin(Imuran), cyclophosphamide (Cytoxan),
chlorambucil (Leukeran), and cyclosporine
(Sandimmune). Because of potentially serious
side effects, immunosuppressive medicines (other
than methotrexate) are generally reserved for
patients with very aggressive disease, or those
with serious complications of rheumatoid
inflammation, such as blood vessel inflammation
(vasculitis). The exception is methotrexate,
which is not frequently associated with serious
side effects and can be carefully monitored with
blood testing. Methotrexate has become a
preferred second-line medication as a
result.
Immunosuppressive medications can depress
bone marrow function and cause anemia, a low
white cell count and low platelets counts. A low
white count can increase the risk of infections,
while a low platelet count can increase the risk
of bleeding. Methotrexate rarely can lead to
liver cirrhosis and allergic reactions in the
lung. Cyclosporin can cause kidney damage and
high blood pressure. Because of potentially
serious side effects, immunosuppressive
medications are used in low doses, usually in
combination with anti-inflammatory
agents.
Newer treatments
Newer "second-line"
drugs for the treatment of rheumatoid arthritis
include leflunomide (Arava), and the "biologic"
medications etanercept (Enbrel), infliximab
(Remicade), anakinra (Kineret), and adalimumab
(Humira).
Leflunomide (Arava) is available to
relieve the symptoms and halt the progression of
the disease. It seems to work by blocking the
action of an important enzyme that has a role in
immune activation. Arava can cause liver
disease, diarrhea, hair loss, and/or rash in
some patients. It should not be taken just
before or during pregnancy because of possible
birth defects.
Other medications that
represent a novel approach to the treatment of
rheumatoid arthritis and are the products of
modern biotechnology. These are referred to as
the biologic medications or biological response
modifiers. In comparison with traditional
DMARDs, the biologic medications have a much
more rapid onset of action and can have powerful
effects on stopping progressive joint damage. In
general, their methods of action are also more
directed, defined, and targeted.
Etanercept (Enbrel),
infliximab (Remicade), and adalimumab (Humira)
are biologic medications. These medications
intercept a protein in the joints (tumor
necrosis factor, or TNF) that causes
inflammation before it can act on its natural
receptor to "switch on " inflammation. This
effectively blocks the TNF inflammation
messenger from calling out to the cells of
inflammation. Symptoms can be significantly, and
often rapidly, improved in patients using these
drugs. Etanercept (Enbrel) must be injected
subcutaneously once or twice a week. Infliximab
(Remicade) is given by infusion directly into a
vein (intravenously). Adalimumab (Humira) is
injected subcutaneously either every other week
or weekly. Each of these medications will be
evaluated by doctors in practice to determine
what role they may have in treating various
stages of rheumatoid arthritis. Research has
shown that biological response modifiers also
prevent the progressive joint destruction of
rheumatoid arthritis. They are currently
recommended for use after other second-line
medications have not been effective. The
biological response modifiers (TNF-inhibitors)
are expensive treatments. They are also
frequently used in combination with methotrexate
and other DMARDs. Futhermore, it should be noted
that the TNF-blocking biologics all are more
effective when combined with methotrexate.
Anakinra (Kineret) is
another biologic treatment that is used to treat
moderate to severe rheumatoid arthritis.
Anakinra (Kineret) works by binding to a cell
messenger protein (IL-1, a proinflammation
cytokine). Anakinra (Kineret) is injected under
the skin daily. Anakinra (Kineret) can be used
alone or with other DMARDs. The response rate of
anakinra (Kineret) does not seem to be as high
as with other biologic medications.
Rituxan (rituximab) is
an antibody that was first used to treat
lymphoma, a cancer of the lymph nodes. Rituxan
can be effective in treating autoimmune diseases
like rheumatoid arthritis because it depletes
B-cells, which are important cells of
inflammation and in producing abnormal
antibodies that are common in these conditions.
Rituxan is now available to treat moderate to
severely active rheumatoid arthritis in patients
who have failed the TNF-blocking biologics.
Preliminary studies have shown that Rituxan was
also found to be beneficial in treating severe
rheumatoid arthritis complicated by blood vessel
inflammation (vasculitis) and
cryoglobulinemia.
Orencia (abatacept) is a recently
developed biologic medication that blocks T-cell
activation. Orencia (abatacept) is now available
to treat adult patients who have failed a
traditional DMARD or TNF-blocking biologic
medication.
While biologic medications are often
combined with traditional DMARDs in the
treatment of rheumatoid arthritis, they are
generally not used with other biologic
medications because of unacceptible risk for
serious infections.
The Prosorba column
therapy involves pumping blood drawn from a vein
in the arm into an apheresis machine, or cell
separator. This machine separates the liquid
part of the blood (the plasma) from the blood
cells. The Prosorba column is a plastic cylinder
about the size of a coffee mug that contains a
sand-like substance coated with a special
material called Protein A. Protein A is unique
in that it binds unwanted antibodies from the
blood that promote the arthritis. The Prosorba
column works to counter the effect of these
harmful antibodies. The Prosorba column is
indicated to reduce the signs and symptoms of
moderate to severe rheumatoid arthritis in adult
patients with long standing disease who have
failed or are intolerant to disease-modifying
anti-rheumatic drugs (DMARDs). The exact role of
this treatment is being evaluated by doctors and
it is not commonly used currently.
Other treatments
There is no special
diet for rheumatoid arthritis. One hundred years
ago it was touted that "night-shade" foods, such
as tomatos, would aggrevate rheumatoid
arthritis. This is no longer accepted as true.
Fish oil may have anti-inflammatory beneficial
effects, but so far this has only been shown in
laboratory experiments studying inflammatory
cells. Likewise, the benefits of cartilage
preparations remain unproven. Symptomatic pain
relief can often be achieved with oral
acetaminophen (Tylenol) or over-the-counter
topical preparations, which are rubbed into the
skin. Antibiotics, in particular the
tetracycline drug minocycline (Minocin), have
been tried for rheumatoid arthritis recently in
clinical trials. Early results have demonstrated
mild to moderate improvement in the symptoms of
arthritis. Minocycline has been shown to impede
important mediator enzymes of tissue
destruction, called metalloproteinases, in the
laboratory as well as in humans.
The areas of the body,
other than the joints, that are affected by
rheumatoid inflammation are treated
individually. Sjogren's syndrome (described
above, see symptoms) can be helped by artificial
tears and humidifying rooms of the home or
office. Medicated eye drops, cortisporine
ophthalmic drops (Restasis), are also available
to help the dry eyes in those affected. Regular
eye check-ups and early antibiotic treatment for
infection of the eyes are important.
Inflammation of the tendons (tendinitis), bursae
(bursitis) and rheumatoid nodules can be
injected with cortisone. Inflammation of the
lining of the heart and/or lungs may require
high doses of oral cortisone.
Proper, regular exercise is important in
maintaining joint mobility, and in strengthening
the muscles around the joints. Swimming is
particularly helpful because it allows exercise
with minimal stress on the joints. Physical and
occupational therapists are trained to provide
specific exercise instructions and can offer
splinting supports. For example, wrist and
finger splints can be helpful in reducing
inflammation and maintaining joint alignment.
Devices, such as canes, toilet seat raisers, and
jar grippers can assist daily living. Heat and
cold applications are modalities that can ease
symptoms before and after exercise.
Surgery may be recommended
to restore joint mobility or repair damaged
joints. Doctors who specialize in joint surgery
are orthopedic surgeons. The types of joint
surgery range from arthroscopy to partial and
complete replacement of the joint. Arthroscopy
is a surgical technique whereby a doctor inserts
a tube-like instrument into the joint to see and
repair abnormal tissues. For more information,
please read the Arthroscopy
article.
"Total joint replacement" is
a surgical procedure whereby a destroyed joint
is replaced with artificial materials. For
example, the small joints of the hand can be
replaced with plastic material. Large joints,
such as the hips or knees, are replaced with
metals. For more information, please read the
Total Hip Replacement and Total Knee Replacement
articles.
Finally, minimizing emotional stress can
help improve the overall health of the patient
with rheumatoid arthritis. Support and
extracurricular groups afford patients time to
discuss their problems with others and learn
more about their illness.
Future treatments
Scientists throughout
the world are studying many promising areas of
new treatment approaches for rheumatoid
arthritis. These areas include treatments that
block the action of the special inflammation
factors, such as tumor necrosis factor
(TNFalpha) and interleukin-1 (IL-1), as
described above. Many other drugs are being
developed that act against certain critical
white blood cells involved in rheumatoid
inflammation. Also, new NSAIDs with mechanisms
of action that are different from current drugs
are on the horizon.
Better methods of more
accurately defining which patients are more
likely to develop more aggressive disease are
becoming available. Recent antibody research has
found that the presence of citrulline antibodies
in the blood (see above in diagnosis) has been
associated with a greater tendency toward more
destructive forms of rheumatoid
arthritis.
Studies involving various types of the
connective tissue collagen are in progress and
show encouraging signs of reducing rheumatoid
disease activity. Finally, genetic research and
engineering is likely to bring forth many new
avenues of earlier diagnosis and accurate
treatment in the near future. Gene profiling,
also known as gene array analysis, is being
identified as a helpful method of defining which
people will respond to which medications.
Studies are underway that are using gene array
analysis to determine which patients will be at
more risk for more aggressive disease. This is
all occurring because of technology
improvements. We are at the threshold of
tremendous improvements in the way rheumatoid
arthritis is managed.

Self-Care
at Home
If
you have joint pain or stiffness, you may think
it is just a normal part of getting older and
that there is nothing you can do. Nothing could
be further from the truth. You have several
options for medical treatment and even more to
help prevent further joint damage and symptoms.
You should discuss these measures with your
health care provider to find ways to make them
work for you.
- First of all, dont delay diagnosis or
treatment. Having a correct diagnosis allows
your health care provider to form a treatment
plan. Delaying treatment increases your risk
that the arthritis will get worse and that you
will develop serious complications.
- Learn everything you can about your
condition. Ask your health care provider if you
have questions. If you want to learn more, ask
him or her to direct you to reliable sources of
information. Some Internet resources are listed
later in this article.
- Become an active participant in your
care. Know the pros and cons of all of your
treatment options, and work with your health
care provider to decide on the best options for
you. Understand your treatment plan and what
benefits and side effects you can expect. If you
dont understand, ask.
- Learn about your symptoms. If you have
rheumatoid arthritis, you probably have both
general discomfort (aches and stiffness) and
pain in specific joints. Learn to tell the
difference. Pain in a specific joint often
results from overuse. Pain in a joint that lasts
more than 1 hour after an activity probably
means that that activity was too stressful and
should be avoided.
Increase your physical
activity.
- Exercise is a very important part of a
complete treatment plan for rheumatoid
arthritis.
- You
may think that exercise is bad for arthritic
joints, but research overwhelmingly shows that
exercise in rheumatoid arthritis helps reduce
pain and fatigue, increases your range of motion
(flexibility) and strength, and keeps you
feeling better overall.
- Three types of exercise are helpful:
range of motion exercise, strengthening
exercise, and endurance (cardio or aerobic)
exercise. Water aerobics are an excellent choice
because they increase range of motion and
endurance while keeping weight off the joints of
your lower body.
- Talk
to your health care provider about how to start
an exercise program and what types of exercises
to do. He or she may refer you to a physical
therapist or exercise
specialist.
Protect your joints.
- At
least once a day, move each joint through its
full range of motion. Do not overdo or move the
joint in any way that causes pain. This helps
keep freedom of motion in your joints
- Avoid situations that are likely to
strain your joints. Remember that your joints
are more susceptible to damage when they are
swollen and painful. Avoid stressing the joint
at such times.
- Learn proper body mechanics. This means
learning to use and move your body in ways that
reduce the stress on your joints. This is
especially true for your hands, since you want
to protect their flexibility. Ask your health
care provider or physical therapist for
suggestions on how to avoid joint
strain.
- Be
creative in thinking up new ways to carry out
tasks and activities.
- Use
the strongest joint available for the job. Avoid
using your fingers, for example, if your wrist
can do the job.
- Take
advantage of assistive devices to carry out
activities that have become difficult. These
simple devices can work very well to reduce
stress on certain joints. Talk to your health
care provider or physical and/or occupational
therapist about this.
Alternate periods of rest and activity
through the day. This is called
pacing.
- General rest is an important part of
rheumatoid arthritis treatment, but avoid
keeping your joints in the same position for too
long a time. Get up and move; use your
hands.
- Holding the joint still for long periods
just promotes stiffness. Keep the joints moving
to keep them flexible.
- If
you must sit for long periods, say at work or
while traveling, take a short break every hour:
stand up, walk around, stretch, and flex your
joints.
- Rest
before you become tired or
sore.
Take part in activities you enjoy every
day.
- This
can improve your outlook and help you put your
arthritis in perspective.
- Some
enjoyable activities are even helpful for your
joints, such as walking, swimming, and light
gardening.
Take steps toward a healthier
lifestyle.
- Losing weight not only helps you look
better, it helps you—and your joints—feel
better. Reducing weight helps take stress
off joints and reduces pain. A healthy
weight also can help you prevent other serious
medical conditions such as heart disease and
diabetes.
- Eat
a varied diet with plenty of fruits and
vegetables, lean proteins, and low-fat dairy
products. Make sure you are getting enough
vitamin C and calcium. Ask your health care
provider if you think you are not getting
sufficient vitamins and minerals.
- Quit
smoking. Not only will you feel better, but also
you will be reducing your risk of complications
of rheumatoid arthritis. You will also be
reducing your risk of lung cancer, emphysema,
and other breathing problems.
Get
the most out of your treatment.
- Take
your medications as directed by your health care
provider. If you think a medication is not
working or is causing side effects, talk to your
health care provider before stopping the
medication. Some medications take weeks or even
months to reach their full benefit. In a few
cases, stopping a medication suddenly can even
be dangerous.
- Help
yourself. If you feel tired and achy, a warm
bath before bed can help you relax and feel
better. Massages feel good and may help increase
your energy and flexibility. Apply an ice pack
or cold compress to a joint to reduce pain and
swelling. (Keep a reusable ice pack in your
freezer or try a bag of frozen
vegetables!)
