Arthritis:
General Concepts > Gout
What is Arthritis?
The term "arthritis" is actually used to describe a group
of distinct diseases, primarily affecting joints of the body, all
having related symptoms. These may include pain, swelling, and stiffness
of the joints and surrounding areas. The word "arthritis"
means, literally, “swelling of the joint.”
Arthritis can attack one or many joints, suddenly or more gradually
over time, depending on the particular type one may have. Symptoms
may be constant or may come and go, but generally the effects
of arthritis are chronic, meaning that they will last for a
long time, perhaps for the rest of your life. A diagnosis of
arthritis does not mean that you are confined to a life of
pain and immobility, however. There are many different treatments
that can lessen pain, increase your range of motion and even
slow the progress of your disease. You should talk to your
doctor about these options. It is important to keep a positive
outlook throughout your treatment, as this will assist in the
healing process.
What is Gout?
Gout is an arthritic condition involving needle-like crystals
which deposit in the joints, causing swelling and extreme pain.
The crystals are uric acid, which is a normal waste product
of the body. Uric acid is normally filtered out of the body
by the kidneys, and is eliminated as urine. In patients with
gout, the level of uric acid rises above normal, and crystals
deposit in the ligaments and cartilage.
The joint most affected in gout is the big toe, though other
joints may also be affected, such as the knee, ankle, foot,
hand, wrist and elbow.
Gout affects more men than women.
Causes of Gout?
Most people who have gout are men who are middle-aged or older,
with the peak age at 75. A very small percentage of cases --
around 5% -- involve women, usually those who have completed
menopause. It is estimated that in the United States alone
one million people suffer from attacks of gout.
Sometimes called "the scourge of the ages," Gout has the
unique distinction of being one of the most frequently recorded medical
illnesses throughout history. It is often related to an inherited
abnormality affecting the body's ability to process uric acid.
Uric acid is a byproduct of the breakdown of purines, a component
of many foods we eat. An abnormality in the production or elimination
of uric acid can cause attacks of gouty arthritis, kidney stones,
and even, in extreme cases, the blockage of the kidney tubules
with uric acid crystals, leading to kidney failure. Many people,
on the other hand, develop elevated uric acid levels -- known
as hyperuricemia -- without experiencing arthritis or kidney
problems.
The relationship between hyperuricemia and gout is unclear.
Many people with hyperuricemia do not develop gout, while some
of those with repeated gout attacks have normal or low uric
acid levels in their blood. Among the male population in the
United States, approximately ten percent have hyperuricemia.
However, only a small portion of those with hyperuricemia actually
develop gout.
Contributing factors and causes of gout include:
- certain foods high in purines, especially meats, seafood, dried
peas and beans, and certain vegetables
- crash diets resulting in sudden weight loss
- dehydration
- obesity
- alcohol abuse
- severe illness, such as cancer or certain types of red blood
cell disorders
- excess cell destruction associated with diuretic drugs or chemotherapy
- gout sometimes appears spontaneously as a result of surgery,
probably related to changes in body fluid balance as patients
temporarily discontinue normal oral fluid intake in preparation
for and recovery from surgery
- many patients with gout have abnormally low thyroid hormone
levels (hypothyroidism)
- a few people have gouty arthritis even though they have normal
uric acid levels
Gout is often inherited. Your body may produce too much uric
acid if you have certain uncommon genetic defects.
While there is no cure for gout, attacks can generally be controlled
with medication and diet.
Symptoms of Gout?
For some reason, the joint most typically affected by gout
is the big toe. The painful inflammation of the first toe joint
is called podagra. The pain may be so severe that a gentle
breeze or a bed sheet brushing up against it may produce exquisite
pain. Subsequent attacks often affect other joints of the foot
and leg (such as the knee and ankle joints) and, less frequently,
the joints of the hand, wrist, and elbow.
In addition to arthritis, gout causes the formation of tophi.
Tophi are lumpy deposits of uric acid crystals just under the
skin. Common places for tophi to develop are in the outer edge
of the ear, on or near the elbow, over the fingers and toes,
and around the Achilles tendon. Sometimes gout results in kidney
stones made of uric acid.
Your doctor will suspect that you have gout if:
- your big toe joint is inflamed
- tests on a sample of fluid withdrawn from the affected joint
indicate that the level of uric acid in your blood is high
- he or she detects hard lumps of uric acid (tophi) deposited
in and around the joints
- there is evidence of decreased kidney function or kidney stones
made of uric acid
- your painful symptoms of arthritis respond to the anti-inflammatory
drug colchicine, which is effective only in treating gouty-type
arthritis
Many people have elevated levels of uric acid for years before
exhibiting any symptoms of gout. They may eventually develop
the symptoms of sudden, severely painful arthritis, perhaps
in only one joint at a time, accompanied by redness and swelling.
Signs of arthritis usually occur before tophi (lumps of uric
acid deposited just under the skin) or kidney stones develop.
Sometimes a sudden attack of gout is related to physical illness,
trauma, a change in diet, or the excessive use of alcohol.
Medications can also affect the level of uric acid in the blood.
It is important to inform your health care provider about all
the medications you are using, both prescription and nonprescription.
The tophi that result from gout do not cause any symptoms unless
they open and drain. Very often they are not painful, but,
depending on their location, they may limit the movement of
joints.
The symptoms of uric acid stones are similar to those of other
kidney stones. They are likely to cause abdominal pain and
other occasional symptoms such as nausea, vomiting, fever,
or blood in the urine.
Treatment of Gout?
The first step in the treatment of gout is clearly identifying
the disease by means of blood tests. These usually reveal an
abnormally high level of uric acid. Your doctor will also inquire
about other aspects of your health, including your diet, consumption
of alcohol, and use of medications. A physician may arange
for your joint to be aspirated (drained) to test the fluid
for uric acid crystals.
If you do have symptoms of gout, it is important to treat the
arthritis or kidney stones. The next treatment objective is
to then try to prevent the recurrence of these problems by
controlling uric acid levels.
The standard treatment for gout is a drug called colchicine.
Although very effective, colchicine may cause nausea, vomiting,
and/or diarrhea. For this reason, many people prefer to use
a nonsteroidal anti-inflammatory drug (NSAID) such as indomethacin
for pain relief during an attack. These medications are sometimes
used on a daily basis to prevent recurrent attacks of gouty
arthritis.
Steroids such as prednisone are sometimes used for the most
severe attacks. Because of their side effects, however, steroids
are not considered a good long term treatment strategy.
If attacks of gout occur frequently, becoming chronic, one
of two additional drugs, allopurinol and probenecid, may be
used. Each of these helps to prevent damaging crystal deposits
in the joints by controlling the production and elimination
of uric acid. These medications are powerful and have side
effects that need to be discussed with your doctor.
Rest, relaxation, proper diet and exercise, and weight management
can all be of benefit in reducing the effects of gouty arthritis.
Exercise is always important in maintaining or achieving health
and wellness. Your doctor will recommend exercises that do
not aggravate your gout, such as walking or swimming. Exercise
helps you to maintain a normal range of motion, keeps joint
cartilage well-lubricated, and strengthens the muscles around
your joints.
Protection of the joints with braces or splints, and the use
of canes, crutches, or a walker can assist you during the painful
episodes while still allowing you to remain relatively active.
Applying hot or cold packs, using a whirlpool, heated pool,
or even taking warm baths may also be helpful as the acute
episode is receding.
Living With Gout?
Because only some individuals with high uric acid levels develop
problems, it is usually not necessary to treat everyone with
medication before the symptoms of gout develop. In special
circumstances (for example, if you have a strong family history
of gouty arthritis or kidney stones) you may be treated for
gout even if you do not have any symptoms other than hyperuricemia.
Gout is one of a number of distinct arthritic diseases, each of which
primarily affects joints of the body. All of these conditions have
related symptoms, most typically pain, swelling, and stiffness of
the joints and surrounding parts of the body. The word arthritis means,
literally, "swelling of the joint."
Arthritis may attack one or many joints, suddenly or more gradually
over time, depending on the particular condition you have.
Symptoms may be constant or they may wax and wane. Generally
the effects of arthritis are chronic, meaning that they can
be expected to last for a long time, perhaps for the rest of
your life. It is important to keep in mind that a diagnosis
of arthritis does not mean you are confined to a life of pain
and immobility.
There are many different treatments that can lessen the pain
of gout, increase your range of motion, and even slow the progress
of your disease. You should talk to your doctor about these
options. Developing a positive outlook assists in the healing
process, and often makes a major difference throughout treatment.
It is important to understand your abilities and limitations
as a result of gout, and to remain optimistic about your management
program. Above all, try to be patient and committed to the
changes in diet or lifestyle your doctor may recommend. The
more active a role you play in the management of your condition,
the better control you will have over gout and other aspects
of your health.
