WHAT'S THE PROBLEM?
Gout is a
genetic or acquired disease where uric acid crystals, a waste
product of protein metabolism, is deposited in joints, producing
an intense inflammatory arthritis.
HOW DOES IT FEEL?
An acute attack of gout is one of
the most painful conditions known to man. Sudden, intense throbbing
pain accompanied by redness and swelling are hallmarks of the
condition. 50% of all acute attacks of gout affect the big
toe joint. Gout is a disease that appears as episodes or attacks.
Even without treatment, the attacks last only 3-5 days, but
the pain is often so severe, that waiting for it to run it's
course is often not possible.
LET'S DO A TEST!
X-rays of the affected joint may show
swelling, and in long standing gouty arthritis, destruction
of the joint. After years of repeated gout attacks, uric acid
crystals may also be seen as faint yellowish masses visible
through the skin around the affected joint. Blood tests may
show an elevated uric acid level, but about 50% of people with
acute gout have a normal uric acid. In most gout attacks, the
level of uric acid peaks quickly and drops back to normal as
just as quickly. The symptoms actually begin to be felt when
the level is already dropping. By the time the patient is seen
in the doctor's office and the blood level of uric acid is
measured, the level is often back to normal. The gold standard
for diagnosis is to remove a sample of joint fluid and look
for the uric acid crystals under the microscope. However, it
is difficult to collect the joint fluid from the small foot
joints and this test is often bypassed. There is a medicine
that is used today that is so effective when used to treat
an acute gout attack, that giving this medicine is now used
as a reliable way to diagnose gout. If the pain goes away after
taking less than 3 doses of the medicine, within a day, then
the condition was most likely a true gout attack. See below
HOW DID THIS HAPPEN?
Gout may be inherited or acquired.
Proteins that we eat are broken down into energy and waste products. One of
the waste products is uric acid. Uric acid is usually dissolved in the blood
and filtered out by the kidneys. Some people either produce too much uric acid
or do not excrete enough through the kidneys. If blood levels rise, uric acid
is deposited in joints, producing an acute attack. The unique properties of
uric acid and the conditions in the small foot joints, including temperature
and pressure, create an environment that allows the uric acid to crystallize
and deposit in the joints, creating an intense inflammatory response. Factors
that may trigger an gout attack are a minor injury to a foot joint, overindulgence
in alcohol or purine-rich foods, and stress, both emotional and physical.
WHAT CAN I DO FOR IT?
The application of warm moist compresses
may give some relief of symptoms. Historically, gout was treated by changing
the patient's diet to reduce intake of protein, but we have come to believe
that the reduction of protein needs to be so complete, that the diet is otherwise
unhealthy, so diet alteration is no longer stressed, with the except noted
below. We do know that regular alcohol use is a strong trigger for a gout attack,
so reduction in this habit is recommended.
WHAT WILL MY DOCTOR DO FOR IT?
In most cases medication will
provide relief of the symptoms of gouty arthritis, however in more extreme
cases, your podiatrist may recommend surgery to remove gouty deposits and remodel
the affected joint. The anti-inflammatory medicine Indocin (Indomethacin) is
so effective when used to treat gout, that after taking 1-3 doses, usually
50 mg after each meal, the pain has gone. A dull ache may linger for a few
days later, and a cortisone injection may be recommended to eliminate this
pain a bit sooner. If a patient experiences repeated attacks, 3 in a 12 month
period, the doctor will recommend taking a medication called Xyloprim (Allopurinol)
to lower the level of uric acid in the blood. This medication is then taken
routinely.
CAN I PREVENT FROM IT HAPPENING AGAIN?
Gout can often be prevented
with medication, some diet modification, and avoidance of triggers, like alcohol
. Purine-rich organ meats such as liver, kidney and brain should be avoided,
as well as shellfish. Your doctor can provide a treatment program tailored
to your individual condition.
