Ulcerative Colitis
Ulcerative
colitis is a chronic, recurring disease of the large bowel. The large
bowel (colon) is the 5 to 6 foot segment of intestine that begins in
the right-lower abdomen, extends upward and then across to the left
side, and downward to the rectum. It dehydrates the liquid stool that
enters it and stores the formed stool until a bowel movement occurs.
When ulcerative colitis affects the colon, inflammation and
ulcers, or sores, form in the lining of the colon. The disease may
involve the entire colon (pancolitis), only the rectum (ulcerative
proctitis) or, more commonly, some area between the two.
Causes
The cause of ulcerative colitis is unknown. Some experts believe
there may be a defect in the immune system in which the body's
antibodies actually injure the colon. Others speculate that an
unidentified microorganism or germ is responsible for the disease. It
is probable that a combination of factors, including heredity, may be
involved in the cause.
Who Develops Ulcerative Colitis?
The disorder can occur in both sexes, all races and all age groups.
It is a disease that usually begins in young people.
Symptoms
The disorder typically begins gradually, with crampy abdominal pain
and diarrhea that is sometimes bloody. In more severe cases, diarrhea
is very severe and frequent. Loss of appetite and weight loss occur.
The patient may become weak and very sick. When the disease is
localized to the rectum, the symptoms are rectal urgency and passage
of small amounts of bloody stool. Usually the symptoms tend to come
and go, and there may be long periods without any symptoms at all.
Usually, however, they recur.
Diagnosis
Diagnosis of ulcerative colitis can be suspected from the
symptoms. Certain blood and stool tests are performed to rule out an
infection that can mimic the disorder. A visual examination of the
lining of the rectum and lower colon (sigmoidoscopy) or the entire
colon (colonoscopy) is always required. This exam typically reveals a
characteristic pattern. Small, painless biopsies are taken which show
certain features of ulcerative colitis. A barium enema x-ray of the
colon is also needed at some point during the course of the disease.
Complications
Most patients with this disease respond well to treatment and go
about their lives with few interruptions. However, some attacks may
be quite severe, requiring a period of bowel rest, hospitalization
and intravenous treatment. In rare cases, emergency surgery is
required. The disease can affect nutrition causing poor growth during
childhood and adolescence. Liver, skin, eye or joint (arthritis)
problems occasionally occur, even before the bowel symptoms develop.
Other problems can include narrowing and partial blocking of the bile
ducts which carry bile from the liver to the intestine. Fortunately,
there is much that can be done about all of these complications.
In
long-standing ulcerative colitis, the major concern is colon cancer.
The risk of developing colon cancer increases significantly when the
disorder begins in childhood, has been present for 8 to 10 years, or
when there is a family history of colon cancer. In these situations,
it is particularly important to perform regular and thorough
surveillance of the colon, even when there are no symptoms. Analysis
of colon biopsies performed during colonoscopy can often predict if
colon cancer will occur. In these cases, preventive surgery is
recommended.
Treatment
There are several types of medical treatments available:
Cortisone, Steroids, Prednisone -- These powerful drugs
usually provide highly effective results. A high dose is often used
initially to bring the disorder under control. Then the drug is
tapered to low, maintenance doses, even to a dose every other day.
These medications are given by pill, enema or intravenously during an
acute attack. In time, the physician will usually try to discontinue
these drugs because of potential long-term, adverse side effects.
Other Anti-inflammatory Drugs -- There are increasing
numbers of these drugs available. They can be given by pill or enema.
The generic and trade names of some of these drugs are sulfasalazine
(Azulfidine), olsalazine (Dipentum), and mesalamine (Asacol, Pentasa
and Rowasa).
Immune System Suppressors -- An overactive immune system is
probably important in causing ulcerative colitis. Certain drugs such
as azathioprine (Imuran), 6-MP (Purinethol), cyclosporine (Neoral,
Sandimmune), and methotrexate (Rheumatrex) suppress the immune system
and at times are effective.
Diet and Emotions
There are no foods known to injure the bowel. However, during an
acute phase of the disease, bulky foods, milk, and milk products can
increase diarrhea and cramping. Generally, the patient is advised to
eat a healthy, well-balanced diet with adequate protein and calories.
A multiple vitamin is often recommended. Iron may be prescribed if
anemia is present.
Stress and anxiety may aggravate symptoms of the disorder, but are
not believed to cause it or make it worse. Any chronic disease can
produce a serious emotional reaction in the patient. This can usually
be handled through discussion with the physician. There are excellent
support groups available in most communities. The Ileitis and Colitis
Foundation is one of them.
Surgery
For patients with longstanding disease that is difficult or
impossible to control with medicine, surgery is a welcomed option. In
these rare cases, the patient's lifestyle and general health have
been significantly affected. Surgical removal of the colon cures the
disease and returns good health and a normal lifestyle to the
patient. In the past a bag, or ileostomy, was required for this
surgery. Advances in surgery now can avoid this problem. The colon is
removed and a pouch or reservoir is created from the small intestine.
Three to six liquid bowel movements occur daily. Most patients are
extremely pleased with this new surgery.
Summary
Most people with ulcerative colitis lead normal, active lives with
few restrictions. Although there is no cure (except by surgery), the
disorder can be managed with present treatments. For a few patients,
the course of the disease may be more difficult and complicated,
requiring more testing and intensive therapy. Surgery sometimes is
required. In all cases, follow-up care with the physician is
essential to monitor the disease and prevent and treat any
complications that arise.
