The severity of the disease can vary, and a patient can experience periods of time when the disease is not active and he or she is symptom free. However, the complications and risks of Crohn’s disease tend to increase over time. Well over 60% of all patients with Crohn’s disease will require surgery, and about half of these patients will require more than one operation over time. About 5-10% of all Crohn’s patients will die of their disease, primarily due to massive infection.

Endoscope
A medical instrument that can be passed into an area of the body (the bladder or intestine, for example) to allow examination of that area. The endoscope usually has a fiber-optic camera that allows a greatly magnified image to be shown on a television screen viewed by the operator. Many endoscopes also allow the operator to retrieve a small sample (biopsy) of the area being examined, to more closely view the tissue under a microscope.

Fistule
An abnormal channel that creates an open passageway between two structures that do not normally connect.

Gastrointestinal tract
The entire length of the digestive system, running from the stomach, through the small intestine, large intestine, and out the rectum and anus.

Immune system
The body system responsible for producing various cells and chemicals that fight infection by viruses, bacteria, fungi, and other foreign invaders. In autoimmune disease, these cells and chemicals turn against the body itself.

Inflammation
The result of the body’s attempts to fight off and wall off an area that is infected. Inflammation results in the classic signs of redness, heat, swelling, and loss of function.

Obstruction
A blockage.

Ulceration
A pitted area or break in the continuity of a surface such as skin or mucous membrane.

Some people have long periods of remission, sometimes years, when they are free of symptoms. However, the disease usually recurs at various times over a person’s lifetime. This changing pattern of the disease means one cannot always tell when a treatment has helped. Predicting when a remission may occur or when symptoms will return is not possible.)

People with Crohn’s disease may feel well and be free of symptoms for substantial spans of time when their disease is not active. Despite the need to take medication for long periods of time and occasional hospitalizations, most people with Crohn’s disease are able to hold jobs, raise families, and function successfully at home and in society

The goal of treatment is to reduce the inflammation that triggers symptoms. Treatment relieves symptoms and results in long-term remission.

Treatment for Crohns disease usually involves medication and/or surgery.Drug therapies must be custom-designed for each patient. Finding which medications best alleviate the symptoms may take time. When a patient with Crohns disease undergoes surgery, it is important that the health care team (including the surgeon, anesthesiologist, and the primary treating physician) know which medications the patient is taking. Many patients with mild to moderate disease are treated with medications containing mesalamine.

These medications differ based on what parts of the bowel are treated. The use of mesalamine to treat Crohns disease, either to achieve or maintain remission, is sometimes controversial because not all studies have consistently shown that mesalamine is effective for Crohns disease. Mesalamine is usually well-tolerated and has no serious side effects. Patients may experience nausea, headache and diarrhea.

Some patients who have severe active disease or do not respond to mesalamine therapy may need corticosteroids such as prednisone to control inflammation and induce remission. These drugs are effective but have significant side effects, such as increased susceptibility to infection, mood swings, anxiety, depression, elevated blood pressure, glaucoma, cataracts and osteoporosis.

Physicians may use different strategies to administer these drugs in order to reduce side effects. Budesonide is a corticosteroid that is rapidly broken down by the liver, resulting in a much lower frequency of side effects. These medications are gradually reduced once remission is achieved — and mesalamine or a drug that suppresses the immune system is used to maintain remission.Antibiotics such as metronidazole are sometimes used to treat Crohns disease.

They are particularly helpful in patients with fistulas and are often combined with other medications. The use of metronidazole to treat active Crohns disease or to delay the recurrence of Crohn’s for the first two to three years after an ileum resection surgery is often controversial because not all studies have consistently shown that metronidazole and other antibiotics are effective in these patient groups.

Metronidazole can be effective in managing perineal Crohns disease (involving the pelvic area). Many patients require surgery because medical therapy does not control their symptoms or because complications such as blockage, abscess, perforation or bleeding into the intestines have developed

It is known that inflammation is part of the body’s immune response, and an immune response is usually triggered by something. But to date no specific “trigger” has been found to cause the inflammatory response seen in Crohns disease.

There is some evidence that Crohns disease has a genetic component. While there is no simple correlation from parent(s) to offspring, the disease tends to “run” in families. As many as 20 to 25 percent of patients with Crohns disease have a relative with CD or ulcerative colitis.

There is also a higher incidence among certain ethnic groups.In addition, some possible environmental factors have been linked to initial episodes or relapses. Crohns disease appears to be a disease that primarily affects those living in Western, industrialized societies. Whether this is due to some condition of the environment in which people live or their diet has not been determined.

The Role Of Heredity
Physicians classify Crohns disease as one of the “familial” or “complex” genetic diseases, as opposed to a “simple” genetic disease. In simple genetic diseases, such as sickle cell disease or cystic fibrosis, a person who inherits a copy of the defective gene from each parent is certain to get the disease. In Crohns disease, this is not the case. In fact, 75 to 80 percent of people with Crohns disease have no relative with either Crohns disease or ulcerative colitis.

But because there are fewer than 500,000 Americans with Crohns disease, the level of multiple incidence in families (20 to 25 percent of Crohn’s patients) means that the risk of being diagnosed with the disease is statistically somewhat higher in individuals who have a family member with either Crohns disease or ulcerative colitis.

Other evidence that suggests a genetic basis for Crohns disease is the fact that populations who have intermarried closely within their communities for many generations, such as Eastern European Jews, have a higher incidence of inflammatory bowel disease than do other groups.

Weakened Immune Response
In the healthy intestine, certain types of bacteria (enteric microflora) are present and necessary. In fact, between one billion and one trillion normal intestinal bacteria exist in every gram of intestinal content. These “normal” bacteria contribute to the process of digestion and keep abnormal bacteria, which can enter the GI tract in food, water, etc., from surviving and causing illness. If abnormal bacteria do survive and multiply, the body recognizes them as invading organisms, or “antigens.”

To a certain extent, these antigens are ignored in the GI tract – the immune system has a certain level of tolerance for them. But immunologic evidence shows that in the intestines of those with inflammatory bowel disease, some of this tolerance for bacteria is lost.

The TH1 cells, which are responsible for activating the immune response against invading organisms, do their job. But the TH2 cells, which are responsible for deactivating the immunologic response after invading organisms are destroyed, fail to perform theirs. The result is an inflammatory overreaction, resulting in pain, fever, and, sometimes, tissue damage.Some evidence also suggests that flare-ups of Crohns disease or ulcerative colitis are a heightened response to seasonal allergies, upper-respiratory infections, or other transient illnesses.

These diseases affect the digestive system and cause the intestinal tissue to become inflamed, form sores and bleed easily. Symptoms include abdominal pain, cramping, fatigue and diarrhea.Crohns disease can affect any part of the gastrointestinal tract, from the mouth to the anus. Patches of inflammation occur, with healthy tissue between the diseased areas.

The inflammation can extend through every layer of affected bowel tissue. Crohns disease can not be cured by drugs or surgery, although either or both can help relieve symptoms.Ulcerative colitis affects only the inner layer of the colon, or large bowel. It always starts in the rectum and may extend as a continuous inflammation from there into the rest of the colon. Usually ulcerative colitis can be controlled with medication. The disease can be completely eliminated by surgically removing the colon, but afterward, waste material may have to be stored and expelled through an external appliance.

While ulcerative colitis causes inflammation only in the colon (colitis) and/or the rectum (proctitis), Crohns disease may cause inflammation in the colon, rectum, small intestine (jejunum and ileum), and, occasionally, even the stomach, mouth, and esophagus.The patterns of inflammation in Crohns disease are different from ulcerative colitis. Except in the most severe cases, the inflammation of ulcerative colitis tends to involve the superficial layers of the inner lining of the bowel. The inflammation also tends to be diffuse and uniform. (All of the lining in the affected segment of the intestine is inflamed.) Unlike ulcerative colitis, the inflammation of Crohns disease is concentrated in some areas more than others and involves layers of the bowel that are deeper than the superficial inner layers. Therefore, the affected segment(s) of bowel in Crohns disease often is studded with deeper ulcers with normal lining between these ulcers.

The most common disease that mimics the symptoms of Crohns disease is ulcerative colitis, as both are inflammatory bowel diseases that can affect the colon with similar symptoms. It is important to differentiate these diseases, since the course of the diseases and treatments may be different. In some cases, however, it may not be possible to tell the difference, in which case the disease is classified as indeterminate colitis.

Currently there is no cure for Crohns disease and remission may not be possible or prolonged if achieved; in cases where remission is possible, relapse can be prevented and symptoms controlled with medication, lifestyle changes and in some cases, surgery. Adequately controlled, Crohns disease may not significantly restrict daily living. Treatment for Crohns disease is only when symptoms are active and involve first treating the acute problem, then maintaining remission.
