Goals of
treatment
There are a variety of treatments available today
for Crohn's disease, and researchers are continuing to develop exciting new
options. The location and severity of your disease, complications, and your
response to previous treatment will all influence your doctor's choice of
therapy.
There are several important goals of treatment recommended by
the American College of Gastroenterology:1
|
Induce and maintain remission |
|
Heal mucosa |
|
Restore and maintain nutrition |
|
Maintain quality of life as it relates to Crohn's
disease |
|
Select optimal timing for those requiring surgical
intervention |
The treatment plan that's right for you may include drugs,
nutrition supplements, surgery, or a combination of these options. At this time,
treatment can help control the disease, but there is no cure.
Some people
may experience long periods of remission when they are free of symptoms. These
periods can last for years. However, the symptoms usually recur at various times
over a person's lifetime. It is not possible to predict when a remission may
occur, or when symptoms will return.
Because of the unpredictability of
Crohn's disease, medical care may be needed for as long as your doctor deems
necessary, with regular office visits to monitor your condition.

Drug
therapy
5-ASA
agents
Corticosteroids
Immunomodulators
Monoclonal
antibody
Antibiotics
Antidiarrheal
medication
5-ASA
agents
Most people are first treated with drugs containing
mesalamine, a substance that helps control inflammation. Sulfasalazine is the
most commonly used of these drugs. If you do not benefit from sulfasalazine or
cannot tolerate it, you may be put on other drugs that contain mesalamine,
generally known as 5-ASA agents.
Possible side effects of mesalamine
preparations include nausea, vomiting, heartburn, diarrhea, and headache.
However, 5-ASA agents are usually well tolerated. These drugs are frequently
effective for mild to moderate, but not severe, inflammation.
Corticosteroids
Corticosteroids help
control inflammation and are very effective for active Crohn's disease, even if
severe. If you respond to steroid treatment, your doctor will usually try to
gradually lower the dose of the steroid in order to avoid some of the
significant side effects of this class of drugs, which include premature
osteoporosis and a greater susceptibility to infection.
Immunomodulators
Drugs that
modulate (alter) the immune system are also used to treat Crohn's disease. Most
commonly prescribed are 6-mercaptopurine (6-MP) and a related drug,
azathioprine. Immunomodulators work by blocking the immune reaction that
contributes to inflammation. You may experience side effects such as nausea,
vomiting, and diarrhea, as well as:2

Lowered red blood cell count

Lowered white blood cell count

Lowered platelet (another type of blood cell) count

Lowered resistance to infection
If you take
these drugs you need to have your blood count monitored on a regular basis. It
often takes several months of treatment for immunomodulators to take
effect.
Monoclonal
antibody
The U.S. Food and Drug Administration has approved
the drug infliximab (brand name, REMICADE™) for the short-term treatment of
moderately to severely active Crohn's disease that does not respond to standard
therapies (mesalamine substances, corticosteroids, and immunomodulators) and for
the treatment of open, draining fistulas. Infliximab inhibits a substance called
tumor necrosis factor alpha (TNF
), a protein
produced by the immune system that plays a central role in the inflammation
associated with Crohn's disease.
Infliximab has been associated with
hypersensitivity reactions that differ in their time of onset. Some people
noticed itching or stinging of the skin and, rarely, other reactions such as
chills, difficulty in breathing, or low blood pressure. Some patients reported
other side effects that did not last long, such as fatigue, fever, headache,
nausea, and dizziness. TNF mediates inflammation and modulates cellular immune
response, including response to infection. Therefore, patients treated with
infliximab may have an increased risk of infection. There are insufficient
safety and efficacy data for the use of infliximab beyond the recommended
duration.
Antibiotics
Antibiotics are used to treat bacterial
overgrowth in the small intestine caused by strictures, fistulas, or prior
surgery. They are also used to treat any bacterial infections that are also
present, including abscesses. Antibiotics may also have a direct effect on
Crohn's disease, especially Crohn's disease of the large intestine. Your doctor
may prescribe one or more of the following antibiotics: ciprofloxacin,
metronidazole, ampicillin.
Antidiarrheal
medications
Diarrhea and abdominal pain are often relieved
when the inflammation subsides, but you may need additional medication. Several
antidiarrheal agents may be prescribed by your doctor, including diphenoxylate,
loperamide, and codeine. If you are dehydrated because of diarrhea, you will be
treated with fluids and electrolytes.

Nutritional supplementation
Your doctor may
recommend nutritional supplementation, with special, high-calorie, vitamin-rich
liquid formulas that are sometimes used for this purpose. A small number of
patients may need periods of intravenous feeding (through a vein). This can help
if you need extra nutrition temporarily, when your intestines need to rest, or
when your intestines cannot absorb enough nutrition from food.

Surgery
The decision to have surgery for Crohn's
disease is made only after careful review of your situation and treatment
history with your doctor. You may require surgery either to relieve symptoms
that do not respond to medical therapy or to correct complications such as
blockage, perforation, abscess, bleeding in the intestine, or fistulas. Surgery
to remove part of the intestine can help. However, at some time after the
surgery, inflammation may return next to the area of intestine that has been
removed.
In most situations, only the diseased section of intestine is
removed. In this operation, the intestine is cut above and below the diseased
area, the diseased section is removed, and the two ends of the intestine are
reconnected.
Some people who have Crohn's disease in the large intestine
need to have their entire large intestine removed in an operation called
colectomy. In this operation, a small opening is made in the front of the
abdominal wall, and the open end of the intestine is brought through a small
opening at the skin's surface. This opening, called a stoma, is about the size
of a quarter and is usually located in the right lower part of the abdomen near
the beltline. A pouch is worn over the opening to collect waste, which is
emptied as needed. The majority of people with colectomies go on to live normal,
active lives.
Because Crohn's disease often recurs after surgery, you
should carefully weigh the benefits and risks of surgery compared with other
treatments. Surgery may not be appropriate for everyone. You should get as much
information as possible from doctors, nurses who work with surgery patients
(enterostomal therapists), and other people who have had the surgery. Patient
advocacy organizations, such as the Crohn's & Colitis Foundation of America
(http://www.ccfa.org/links/)
can suggest support groups and other information resources.
You may feel
well and be free of symptoms when your disease is not active. Despite the need
to take medication for long periods of time and occasional hospitalizations and
possibly surgery, most people with Crohn's disease are able to hold jobs, raise
families, and function successfully at home and in society.
