Crohns Disease Prognosis

12.09.09

Crohn’s disease is a life-long illness. 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

Crohns Disease

08.20.09

It is also known as regional enteritis is a chronic, episodic, inflammatory bowel disease (IBD) that affects any part of the entire wall of the bowel or intestines. Crohns disease can affect any part of the gastrointestinal tract from mouth to anus; as a result, the symptoms of Crohns disease vary among afflicted individuals.

The disease is characterized by areas of inflammation with areas of normal lining between in a symptom known as skip lesions. The main gastrointestinal symptoms are abdominal pain, diarrhea (which may be bloody, though this may not be visible to the naked eye), constipation, vomiting, weight loss or weight gain. Crohns disease can also cause complications outside of the gastrointestinal tract such as skin rashes, arthritis, and inflammation of the eye.

The disease was independently described in 1904 by Polish surgeon Antoni Lesniowski and in 1932 by American gastroenterologist Burrill Bernard Crohn, for whom the disease was named. Crohn, along with two colleagues, described a series of patients with inflammation of the terminal ileum, the area most commonly affected by the illness.

Crohns disease affects between 400,000 and 600,000 people in North America. Prevalence estimates for Northern Europe have ranged from 27–48 per 100,000. Crohns disease tends to present initially in the teens and twenties, with another peak incidence in the fifties to seventies, although the disease can occur at any age. Although the cause of Crohns disease is not known, it is believed to be an autoimmune disease that is genetically linked. The highest relative risk occurs in siblings, affecting males and females equally. Smokers are three times more likely to get Crohns disease.

Unlike the other major types of IBD, there is no known drug based or surgical cure for Crohns disease. Treatment options are restricted to controlling symptoms, putting and keeping the disease in remission and preventing relapse. Crohns disease is a chronic inflammatory disease of the intestines. It primarily causes ulcerations (breaks in the lining) of the small and large intestines, but can affect the digestive system anywhere from the mouth to the anus. It is named after the physician who described the disease in 1932.

It also is called granulomatous enteritis or colitis, regional enteritis, ileitis, or terminal ileitis. Crohns disease tends to be more common in relatives of patients with Crohns disease. It also is more common among relatives of patients with ulcerative colitis. Crohns disease is related closely to another chronic inflammatory condition that involves only the colon called ulcerative colitis.

Together, Crohns disease and ulcerative colitis are frequently referred to as inflammatory bowel disease (IBD). Ulcerative colitis and Crohns disease have no medical cure.

Colitis Ulcerosa

07.13.09

Ulcerative colitis (Colitis ulcerosa, UC) is a form of inflammatory bowel disease (IBD). Ulcerative colitis is a form of colitis, a disease of the intestine, specifically the large intestine or colon, that includes characteristic ulcers, or open sores, in the colon.

The main symptom of active disease is usually diarrhea mixed with blood, of gradual onset. Ulcerative colitis is, however, a systemic disease that affects many parts of the body outside the intestine. Because of the name, IBD is often confused with irritable bowel syndrome (“IBS”), a troublesome, but much less serious condition. Ulcerative colitis has similarities to Crohns disease, another form of IBD.

Ulcerative colitis is an intermittent disease, with periods of exacerbated symptoms, and periods that are relatively symptom-free. Although the symptoms of ulcerative colitis can sometimes diminish on their own, the disease usually requires treatment to go into remission.Ulcerative colitis is a rare disease, with an incidence of about one person per 10,000 in North America.

The disease tends to be more common in northern areas. Although ulcerative colitis has no known cause, there is a presumed genetic component to susceptibility. The disease may be triggered in a susceptible person by environmental factors. Although dietary modification may reduce the discomfort of a person with the disease, ulcerative colitis is not thought to be caused by dietary factors. Although ulcerative colitis is treated as though it were an autoimmune disease, there is no consensus that it is such.

Treatment is with anti-inflammatory drugs, immunosuppression (suppressing the immune system), and biological therapy targeting specific components of the immune response. Colectomy (partial or total removal of the large bowel through surgery) is occasionally necessary, and is considered to be a cure for the disease. Ulcerative colitis is a relatively uncommon, chronic, recurrent inflammatory disease of the colon or rectal mucosa. Often a lifelong illness, the condition has profound emotional and social impact on the affected individual. Ulcerative colitis is defined as continuous idiopathic inflammation of the colonic or rectal mucosa.

The rectum is involved in more than 95% of cases. Some authorities believe that the rectum is always involved in an untreated patient. Partial healing may occur in a patient treated with topical therapy, creating diagnostic confusion. Ulcerative colitis occurs more frequently in white people. The incidence of ulcerative colitis is reported to be 2-4 times higher in Jewish people. However, recent population studies in North America do not completely support this assertion. Ulcerative colitis seems to have a female preponderance. Ulcerative colitis affects 30% more females than males. The incidence of ulcerative colitis peaks in people aged 15-25 years and in people aged 55-65 years, although it can occur in people of any age.
