Objective:
To identify changes over the past decade in physicians' attitudes regarding the use of immunomodulatory agents for the treatment of children with inflammatory bowel disease (IBD), we surveyed the membership of the North American Society for Pediatric Gastroenterology and Nutrition and compared the responses to those from an identical survey performed in 1990.
Methods:
Surveys were mailed to 718 physicians in January, 2000. All surveys returned by mid-February were analyzed, and results compared to those obtained in the 1990 survey.
Results:
Thirty-nine percent (278/718) of surveys were returned, compared to 27% (105/385) in 1990. Overall, 93% of the current survey's respondents agreed with the statement "immunomodulatory agents are effective in the treatment of children and adolescents with IBD." Compared to 1990, significant increases (p < 0.0001) were noted in the percentage of respondents who prescribe immunomodulatory agents to children with all forms of IBD. Indications for immunomodulation that showed significant increases (p < 0.001) since 1990 included treatment of perianal and non-perianal fistulae; growth failure; use as initial, primary therapy; and use as prophylaxis against postoperative recurrence. 6-Mercaptopurine and azathioprine continue to be the agents prescribed by the greatest percentage of respondents. More physicians are willing to use immunomodulatory agents in children younger than 5 yr, and duration of use is longer than in 1990. Currently, physicians seem to favor the use of immunomodulatory agents over colectomy for children with either intractable ulcerative or Crohn's colitis. Most respondents remain concerned about potential bone marrow and immune suppression, but concerns regarding malignancy, teratogenicity, and infertility have lessened.
Conclusion:
These survey findings document that pediatric gastroenterologists have widely accepted the use of immunomodulators in the treatment of children and adolescents with IBD.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
