Pediatric Inflammatory Bowel Disease (pediatric + inflammatory_bowel_disease)
Selected AbstractsCourse and treatment of perianal disease in children newly diagnosed with Crohn's diseaseINFLAMMATORY BOWEL DISEASES, Issue 3 2009David J. Keljo MD Abstract Background: We sought to characterize perianal disease and its treatment in pediatric patients newly diagnosed with Crohn's disease. Methods: Data were obtained from the Pediatric Inflammatory Bowel Disease (IBD) Collaborative Group Registry, a prospective, multicenter observational registry recording clinical and laboratory outcomes in children under 16 years of age newly diagnosed with IBD. Patients with Crohn's disease were selected who had data on perianal disease and at least 24 months of follow-up. The records of patients with a Pediatric Crohn's Disease Activity Index perianal subscore greater than 0 were reviewed, and patients with abscesses or fistulas were selected. The therapies used and the course of their perianal disease were then assessed. Results: Of the 276 patients identified, 41 had perianal lesions within 30 days of diagnosis. Thirteen of these had skin tags and fissures only, whereas 28 had fistulas and/or abscesses. The latter lesions resolved by 1 year in 20 patients, and 8 had chronic/recurrent perianal disease persisting for more than 1 year following diagnosis. Patients with fistulizing disease were much more likely to be treated and were treated earlier with antibiotics, infliximab, and immunomodulators than were nonfistulizing patients. Patients who developed chronic perianal disease were more likely to have low body mass indices and required more perianal surgery than did patients whose perianal disease resolved. Conclusions: Approximately 10% of newly diagnosed pediatric patients with Crohn's disease will have perianal fistulas and/or abscesses at the time of diagnosis. Most of these will resolve within a year with medical therapy alone.

The aim was to compare FC levels in IBD and healthy controls, to correlate FC levels with clinical disease activity, and to assess whether FC levels can be used to predict clinical relapse in children with IBD. Methods: Enzyme-linked immunosorbent assay (ELISA) determined levels of FC were measured in more than 1 stool samples (n) from 32 IBD patients (n = 97) and from 34 healthy controls (n = 37). Disease activity was assessed by the Harvey,Bradshaw index in Crohn's disease (CD) and by Physician's Global Assessment (PGA) in both CD and ulcerative colitis (UC). Clinical events were recorded up to 9 months following stool collection in CD patients. Wilcoxon rank sum test and Fisher's exact tests were used to compare FC levels in IBD patients and in control. Kaplan,Meyer analysis was used to determine a risk of clinical relapse in relation to FC levels. Results: The IBD group had higher FC levels (range 17,7500 g/g) compared with control (16,750 g/g, P < 0.0001). FC levels were higher during relapse (CD, 3214 ± 2186; UC, 2819 ± 1610) compared to remission (CD, 1373 ± 1630; UC, 764 ± 869; P < 0.0001). Among those with clinical relapse, 90% had FC levels more than 400 ,g/g in CD. Eighty-nine percent of CD encounters with FC levels less than 400 ,g/g remained in clinical remission. Conclusions: FC levels differentiate active IBD from controls. Among children with CD and in remission, FC levels may be useful in predicting impending clinical relapse. (Inflamm Bowel Dis 2008) [source] A population-based study of the frequency of corticosteroid resistance and dependence in pediatric patients with Crohn's disease and ulcerative colitis,INFLAMMATORY BOWEL DISEASES, Issue 12 2006Jeanne Tung MD 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. [source] Pharmacokinetics of mesalazine pellets in children with inflammatory bowel diseaseINFLAMMATORY BOWEL DISEASES, Issue 5 2004Heleen Wiersma MD Abstract Mesalazine is a first-line drug in pediatric inflammatory bowel disease (IBD), and is customarily used to induce and maintain remission in mild to moderate disease. In children, pharmacokinetic data are scarce, and dosage recommendations are largely extrapolated from studies in adults. Aim of the study was to obtain the pharmacokinetic profile of a new mesalazine pellet formulation in children with ulcerative colitis and Crohn's colitis. A single oral dose of 20 mg/kg mesalazine was administered to 13 patients (age 6,16 years). Serial blood and urine sampling for determination of mesalazine and acetylmesalazine was performed before and during 24 hours following ingestion. Maximum plasma concentration of mesalazine (Cmax) was 1332 ng/mL (geometric mean, geometric coefficient of variation [CV]: 0.57), obtained 3.7 hours (tmax; CV: 0.31) after drug administration. Systemic exposure as determined by area under the plasma concentration-time curve (AUC0,, ) was 8712 ng/ml*h (CV: 0.44). Terminal half-life of elimination of mesalazine was 3.5 hours (t1/2; CV: 1.43). This study presents extensive pharmacokinetic data on mesalazine in children with mild-moderately active ulcerative colitis and Crohn's colitis. In comparison with previous experience in adults, pharmacokinetics of mesalazine administered as pellets appear to be similar in both populations. [source] | ||||||||||
