Clinical Outcome of Treatment of Ulcerative Colitis in Adult.

Ulcerative colitis is an idiopathic inflammatory condition of the colon which results in diffuse friability and superficial erosions on the colonic wall associated with bleeding. It is the most common form of inflammatory bowel disease worldwide. It characteristically involves inflammation restricted to the mucosa and submucosa of the colon. Typically, the disease starts in the rectum and extends proximally in a continuous manner. In the United States, the disease accounts for a quarter-million provider visits annually, and medical costs directly related to the disease are estimated to exceed four billion dollars annually.Ulcerative has no cure and is a lifelong disorder with a significant impact on both physical and mental health. The specific cause of inflammatory bowel disease is not known. There seems to be a primary genetic component since the most important independent risk factor is a family history of the disease (8% to 14% of patients). A first-degree relative of a patient with ulcerative colitis has a four times higher risk of developing the disease. Although there is little evidence to support this, it has been postulated that alterations in the composition of the gut microbiota and defects in mucosal immunity could lead to ulcerative colitis. Autoimmunity may also play an important role in the etiology of ulcerative colitis.Diagnosis of ulcerative colitis is made clinically with supportive findings on endoscopy, biopsy, and by negative stool examination for infectious causes. Because colonic infection can produce clinical findings indistinguishable from idiopathic ulcerative colitis, microbiologic studies for bacterial infection and parasitic infestation should be included in the initial evaluation.Treatment choice for patients with ulcerative colitis is based on both the extent of the disease and the severity. The prognosis during the first decade after diagnosis is often generally good, and most patients go into remission. Rectal application of medical therapy, via suppository or enema, is usually appropriate for isolated distal disease (proctitis); however, a rectal application is usually used in combination with systemic therapy to help target the distal colon and therefore decrease tenesmus.Ulcerative colitis has no cure and despite treatment, many continue to have increased bouts of stool frequency. An increase in mortality is usually seen in elderly patients, those with complications like infection, shock, anemia, and those who require repeated surgical interventions. Data show that when the disease involves the muscularis propria, it can lead to bowel dysmotility, necrosis, and gangrene. A certain number of patients also develop toxic megacolon with poor outcomes. It is estimated that about 5% of patients will develop colorectal cancer over time. The risk of colon cancer is higher in patients with pancolitis and in patients whose disease started before the age of 15. Overall, the quality of life in patients with ulcerative colitis is poor.
