Abstract: Knowledge about the clinical pharmacology of medical therapy of inflammatory bowel disease has incrementally advanced. Small studies with mesalamine have suggested that intestinal mucosal concentrations of mesalamine may predict clinical response to mesalamine therapy. Increased expression of glucocorticoid receptor beta and increased expression of the multidrug resistance drug pump P-glycoprotein 170 have been proposed as markers of drug resistance to glucocorticoids. A baseline determination of thiopurine methyltransferase phenotype or genotype may predict early leukopenia in patients treated with azathioprine or 6- mercaptopurine. Serial measurement of erythrocyte 6-thioguanine nucleotides may be useful in tailoring the dose of these medications. A loading dose of intravenous azathioprine does not accelerate the time to response in patients with steroid-treated Crohn's disease; however, standard azathioprine may work more quickly than previously reported. Methotrexate, 15 to 25 mg/wk, is effective for the treatment of Crohn's disease (active or in remission), and there is no significant difference in the erythrocyte concentrations of methotrexate polyglutamate in patients with inflammatory bowel disease receiving 15 mg, compared with 25 mg, subcutaneously on a weekly basis.

Abstract: BACKGROUND: The goal of this study was to examine the 1-year outcome after the first course of systemic corticosteroids in an inception cohort of pediatric patients with inflammatory bowel disease. METHODS: All Olmsted County (Minnesota) residents diagnosed with Crohn's disease (n = 50) or ulcerative colitis (n = 36) before 19 years of age from 1940 to 2001 were identified. Outcomes at 30 days and 1 year after the initial course of corticosteroids were recorded. RESULTS: Twenty-six patients with Crohn's disease (65%) and 14 with ulcerative colitis (44%) were treated with corticosteroids before age 19. Thirty-day outcomes for corticosteroid-treated Crohn's disease were complete remission in 16 (62%), partial remission in 7 (27%), and no response in 3 (12%), with 2 of these patients requiring surgery. Thirty-day outcomes for treated ulcerative colitis were complete remission in 7 (50%), partial remission in 4 (29%), and no response in 3 (21%). One-year outcomes for Crohn's disease were prolonged response in 11 (42%) and corticosteroid dependence in 8 (31%), whereas 7 (27%) were postsurgical. One-year outcomes for ulcerative colitis were prolonged response in 8 (57%) and corticosteroid dependence in 2 (14%), whereas 4 (29%) were postsurgical. CONCLUSIONS: Most pediatric patients with inflammatory bowel disease initially responded to corticosteroids. However, after 1 year, 58% of pediatric patients with Crohn's disease and 43% of pediatric patients with ulcerative colitis either were steroid dependent or required surgery. This finding emphasizes the need for early steroid-sparing medications in pediatric inflammatory bowel disease.

Abstract: It is estimated that of the >1 million individuals in the United States with inflammatory bowel disease (IBD), approximately 100,000 are children. IBD that begins in childhood affects the individual at a critical period of growth and development. Children with Crohn's disease and ulcerative colitis may experience complications such as growth failure, school absence, and depression. In addition, because children with IBD have fewer environmental confounders such as smoking, children may be an excellent population to study microbial and immune interactions. Despite these opportunities, the discipline of pediatric IBD investigation is still in its infancy. In September of 2005, a group of investigators with expertise in pediatric IBD met in Boston (Massachusetts) to review the current status of childhood IBD research and to develop research priorities that warranted funding from the Crohn's and Colitis Foundation of America. The group included pediatricians, internists, basic scientists, clinical investigators, and members of the administrative staff and board of the Crohn's and Colitis Foundation of America. The research needs in respective areas were outlined by the heads of 10 focus groups, each with expertise in their respective fields (genetics, psychosocial issues, epidemiology, microbiology, immunology, quality improvement, pharmacogenomics, nutrition, growth and skeletal health, and clinical trials). Before the conference, heads of the research focus groups developed their proposals with experts in the field. At the end of the conference, members of the focus groups and members of the steering committee rated the proposed areas of study in terms of feasibility and importance. It was recommended that the Crohn's and Colitis Foundation of America focus its initial efforts in pediatric IBD in 5 areas: the effects of inflammation on growth and skeletal development, the genetics of early-onset IBD, the development of quality improvement interventions to standardize and improve clinical care of children with IBD, the immunology of childhood IBD, and the diagnosis and treatment of psychosocial sequelae of childhood IBD. At the conclusion of the meeting, investigators discussed the formation of a multicenter collaborative network to advance clinical and basic research in the field.

Abstract: BACKGROUND: Delayed release budesonide was approved by the FDA for the treatment of mildly to moderately active Crohn's disease involving the ileum and ascending colon. Controlled trials have demonstrated that budesonide is effective in inducing remission and for maintenance of remission, with less frequent steroid side effects than conventional steroids. We sought to determine the benefit of this medication in clinical practice and to identify any non-FDA-approved uses that may warrant further study. METHODS: Patients in whom oral budesonide was prescribed between November 1, 2001 and October 31, 2002, were identified and medical records were reviewed. Patients were categorized by indication for therapy: ileocolonic Crohn's disease (group 1), Crohn's disease elsewhere (group 2), and other conditions (group 3). RESULTS: A total of 225 patients were identified (108 in group 1, 62 in group 2, and 55 in group 3). Group 3 included patients with microscopic colitis (n = 28), pouchitis (n = 13), ulcerative colitis (n = 12), and celiac disease (n = 2). A favorable outcome occurred in 61% of group 1 patients but only 24% of patients in group 2. In group 3, only microscopic colitis patients and pouchitis patients experienced response rates >50% (77% and 60%, respectively). CONCLUSION: Budesonide is effective in a majority of patients with ileocolonic Crohn's disease and microscopic colitis, which is consistent with results reported from clinical trials. A majority of patients with pouchitis also benefit from budesonide therapy, but prospective controlled trials are necessary to clarify the benefit in this group.

Abstract: BACKGROUND: Inflammatory bowel disease (IBD) in adults with primary sclerosing cholangitis (PSC) is characterized by pancolonic involvement, a high frequency of rectal sparing, and an increased risk of pouchitis and colorectal neoplasia. The clinical features of IBD in pediatric patients with PSC have not been well described. The aim of this study was to characterize the frequency, clinical features, and natural history of IBD in pediatric patients diagnosed with PSC. METHODS: A retrospective chart review was performed for all patients 18 years of age or younger diagnosed with PSC seen at the Mayo Clinic between 1975 and 1999. Endoscopic and histologic features and surgical and postsurgical outcomes were recorded. RESULTS: Fifty-two children with PSC were identified. Forty-three patients (84%) were also diagnosed with IBD. In 36 of 43 cases, there was a sufficient diagnostic evaluation to allow a detailed review. Thirty-two of 36 patients (89%) had ulcerative colitis and 4 of 36 patients (11%) had Crohn's disease. In 4 of 36 patients (11%), IBD was asymptomatic. Although the most frequent endoscopic presentation of IBD was universal colitis, endoscopic rectal sparing was frequently noted (27% of colonoscopic studies). Of the four patients diagnosed with Crohn disease, in none did perianal, fistulizing, or stricturing disease develop. Proctocolectomy was performed in six patients (17%); three operations were performed for dysplasia. Pouchitis complicated four of the five ileal pouch-anal anastomoses procedures. CONCLUSIONS: Among pediatric patients (1) PSC without IBD is uncommon; (2) asymptomatic IBD may be associated with PSC; (3) because the time to dysplasia may be accelerated, once the diagnosis of IBD is made in the setting of PSC, heightened endoscopic surveillance may be indicated; (4) pouchitis occurs frequently in these patients.

Abstract: BACKGROUND & AIMS: The aim of this study was to determine the 1-year outcome after the first course of corticosteroids in an inception cohort of patients with inflammatory bowel disease. METHODS: All patients in Olmsted County, Minnesota, diagnosed with Crohn's disease (n = 173) or ulcerative colitis (n = 185) from 1970 to 1993 who were treated with systemic corticosteroids were identified (4 denied research authorization). Immediate outcome (30 days) and 1-year outcome after the first course of corticosteroids were determined. RESULTS: Seventy-four (43%) patients with Crohn's disease and 63 (34%) with ulcerative colitis were treated with corticosteroids. Immediate outcomes for Crohn's disease were complete remission in 43 (58%), partial remission in 19 (26%), and no response in 12 (16%). Immediate outcomes for ulcerative colitis were complete remission in 34 (54%), partial remission in 19 (30%), and no response in 10 (16%). One-year outcomes for Crohn's disease were prolonged response in 24 (32%), corticosteroid dependence in 21 (28%), operation in 28 (38%), and lost to follow-up in 1 (1%). One-year outcomes for ulcerative colitis were prolonged response in 31 (49%), corticosteroid dependence in 14 (22%), and operation in 18 (29%). CONCLUSIONS: Most patients with Crohn's disease and ulcerative colitis initially respond to corticosteroids. At 1 year, 32% of patients with Crohn's disease and 48% with ulcerative colitis are corticosteroid free without operation.
