Abstract
The relationship between the host and its microbiota is challenging to understand because both microbial communities and their environments are highly variable. We have developed a set of techniques based on population dynamics and information theory to address this challenge. These methods identify additional bacterial taxa associated with pediatric Crohn disease and can detect significant changes in microbial communities with fewer samples than previous statistical approaches required. We have also substantially improved the accuracy of the diagnosis based on the microbiota from stool samples, and we found that the ecological niche of a microbe predicts its role in Crohn disease. Bacteria typically residing in the lumen of healthy individuals decrease in disease, whereas bacteria typically residing on the mucosa of healthy individuals increase in disease. Our results also show that the associations with Crohn disease are evolutionarily conserved and provide a mutual information-based method to depict dysbiosis.

Abstract
Inflammatory bowel diseases (IBD) are emerging globally, indicating that environmental factors may be important in their pathogenesis. Colonic mucosal epigenetic changes, such as DNA methylation, can occur in response to the environment and have been implicated in IBD pathology. However, mucosal DNA methylation has not been examined in treatment-naïve patients. We studied DNA methylation in untreated, left sided colonic biopsy specimens using the Infinium HumanMethylation450 BeadChip array. We analyzed 22 control (C) patients, 15 untreated Crohn’s disease (CD) patients, and 9 untreated ulcerative colitis (UC) patients from two cohorts. Samples obtained at the time of clinical remission from two of the treatment-naïve UC patients were also included into the analysis. UC-specific gene expression was interrogated in a subset of adjacent samples (5 C and 5 UC) using the Affymetrix GeneChip PrimeView Human Gene Expression Arrays. Only treatment-naïve UC separated from control. One-hundred-and-twenty genes with significant expression change in UC (> 2-fold, P < 0.05) were associated with differentially methylated regions (DMRs). Epigenetically associated gene expression changes (including gene expression changes in the IFITM1, ITGB2, S100A9, SLPI, SAA1, and STAT3 genes) were linked to colonic mucosal immune and defense responses. These findings underscore the relationship between epigenetic changes and inflammation in pediatric treatment-naïve UC and may have potential etiologic, diagnostic, and therapeutic relevance for IBD.

Abstract
Background Inflammatory bowel disease (IBD)-indeterminate is a subgroup of IBD that has features of both ulcerative colitis (UC) and Crohn’s disease (CD). Aims To determine the clinical course of IBD-indeterminate in children over a 25 year period. Methods We performed a retrospective investigation on children diagnosed with IBD. Diagnosis and disease distribution of IBD was based on clinical, radiologic, endoscopic, and histologic examinations. Results Four hundred and twenty children diagnosed with IBD between 1986 and 2003 were identified from the IBD registry, 78 (22%) of whom were diagnosed with IBD-indeterminate. The mean age at diagnosis was 9.2 ± 4 years and the mean follow-up period was 4.1 ± 2 years. In 2003, 18 of 78 children (23%) were reclassified by the same physician based on the endoscopic and pathologic findings as follows: eight children with CD, five children with UC, and five children with non-IBD (eg, eosinophilic colitis). During 2011, 20 of the 60 patients who had maintained an IBD-indeterminate diagnosis were located and contacted, and detailed telephone interviews were conducted by the corresponding author. Two patients were reclassified as having CD (10%), one patient was reclassified as having eosinophilic colitis (5%), six patients remained with IBD-indeterminate (30%), and eleven patients (55%) reported a complete resolution of their symptoms. The follow-up period ranged from 10–18 years (mean 12.5 ± 3 years). Children who were reclassified as having CD were significantly younger than those who maintained an IBD-indeterminate diagnosis (6.4 ± 4 years versus11.2 ± 3 years, respectively, P = 0.05). Conclusion Children with IBD-indeterminate remain classified as IBD-indeterminate, or were clinically reclassified as CD or non-IBD, or became asymptomatic as they transitioned into adulthood. The need for IBD-indeterminate classification is of importance, especially when deciding on management and treatment.

Abstract
BACKGROUND The natural history of ulcerative colitis (UC) has been poorly studied in children. METHODS We performed a retrospective study in children diagnosed with UC with a follow-up. The diagnosis of UC was based on clinical, radiologic, endoscopic, and histologic examinations. We estimated the occurrence of colectomy, proctitis, and extraintestinal manifestations (EIMs) at the onset of the diagnosis and at the end of the study period. RESULTS We identified 115 UC patients between 1986 and 2003 with a mean age at diagnosis of 10.6 ± 5.1 years. The cumulative rate of colectomy was 4.1% at 1 year, and 16% at 10 years. EIMs were experienced by 20% of the children; 48% had arthritis, 35% had sclerosing cholangitis, and 17% had aphthous stomatitis. Proctitis was noted in 29 patients and it was not associated with an increased risk of colectomy (relative risk = 1.4; 95% CI = 0.7-4.5), and girls were twice more likely to develop proctitis. The pathologic reading for disease extensions was recorded for all children at entry and only 62 children had pathological results at maximum follow-up. At entry, 25% of the children only had ulcerative proctitis (E1) localization, 40% had left-sided UC (E2), and 35% had extensive UC (E3). Among the patients with E1 localization, 20% had progressed to E2 and 80% had progressed to E3; among the patients with E2 localization, 40% had progressed to E3. Age, gender, and EIMs at time of diagnosis were not associated with extension of disease at maximal follow-up. The Z score of body mass index (BMI) of children was significantly higher at the end of the study. At diagnosis, 85% of patients received 5-aminosalicyclic acid, 60% received steroids, and 11% received an immunomodulator. The majority of patients were still using systemic steroids at and after 5 years from their entry date. Only 32 of the 91 children on steroids did not receive an immunomodulator. CONCLUSION Pediatric UC is associated with high rates of EIMs and colectomy that are not dependent on age, gender, or race, but is associated with a high rate of proctitis among girls. Understanding the clinical course of UC can optimize therapeutic interventions.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) has a wide spectrum and variability among different ethnic groups. We aimed to evaluate disease characteristics in the pediatric Hispanic population, which has not been well studied. METHODS We identified patients <18 years old seen at Texas Children's Hospital (TCH) and diagnosed with IBD between 2004 and 2009. We compared them with their White, African American, and "other" counterparts with regard to their demographics, disease characteristics, and initial therapy. RESULTS There were a total of 399 patients with IBD: 211 (52.9%) White, 67 (16.8%) African American, 53 (13.3%) Hispanic, and 68 (17%) "other." Crohn's disease (CD) was the most common IBD type among all groups; however, Hispanics had the highest proportion of patients with ulcerative colitis (UC) and IBD-unclassified (IBD-U). There was male predominance in all groups except African Americans. Hispanics had the highest percentage of Medicaid coverage (P < 0.01) and none of the Hispanics had a first-degree relative with IBD. They had a younger age at diagnosis but a similar duration of symptoms prior to diagnosis. Hispanics had less failure to thrive and a higher body mass index (BMI) Z-score. Hispanics with CD more often received systemic steroids while those with UC and IBD-U were more often treated with local steroids (P < 0.01), oral 5-aminosalicylate (P < 0.01), and less often received immunomodulators or biologics (P = 0.05). CONCLUSIONS We demonstrate differences in disease characteristics between Hispanics and other ethnicities with IBD. Further epidemiologic studies are needed, including longer-term follow-up, to better define the burden of illness in Hispanics.

Abstract
BACKGROUND The development of disease complications is poorly characterized in pediatric patients with Crohn's disease (CD). METHODS We retrospectively determined the cumulative incidence of stricturing and penetrating complications of CD prior to first surgery utilizing data from 989 consecutively enrolled CD patients (age 0-17 years at diagnosis) collected between January 2000 and November 2003 and stored in the Pediatric IBD Consortium Registry. RESULTS Mean age at diagnosis was 11.5 +/- 3.8 (standard deviation) years. Median follow-up time was 2.8 years. Prior to first surgery, the cumulative incidence of stricturing or penetrating complications was 27% at 5 years and 38% at 10 years from the diagnosis of inflammatory bowel disease. The cumulative incidence of complicated disease was lowest in isolated colonic disease (P = 0.009). Penetrating complications that followed stricturing complications prior to first surgery occurred within 2 years of stricturing complications (cumulative incidence was 13% at 2 years from diagnosis of stricturing disease). Stricturing complications that followed penetrating complications prior to first surgery occurred within 8 years of penetrating complications (cumulative incidence was 26% at 8 years from diagnosis of penetrating complications). CONCLUSIONS Strictures, abscesses, and fistulas are common in pediatric CD. Earlier aggressive management may be indicated. Prospective study is required to identify genetic and serologic markers that predict a patient's risk for the development of complicated disease and to determine optimal treatment regimens.

Abstract
The inflammatory bowel diseases (IBD) Crohn's disease and ulcerative colitis are common causes of morbidity in children and young adults in the western world. Here we report the results of a genome-wide association study in early-onset IBD involving 3,426 affected individuals and 11,963 genetically matched controls recruited through international collaborations in Europe and North America, thereby extending the results from a previous study of 1,011 individuals with early-onset IBD. We have identified five new regions associated with early-onset IBD susceptibility, including 16p11 near the cytokine gene IL27 (rs8049439, P = 2.41 x 10(-9)), 22q12 (rs2412973, P = 1.55 x 10(-9)), 10q22 (rs1250550, P = 5.63 x 10(-9)), 2q37 (rs4676410, P = 3.64 x 10(-8)) and 19q13.11 (rs10500264, P = 4.26 x 10(-10)). Our scan also detected associations at 23 of 32 loci previously implicated in adult-onset Crohn's disease and at 8 of 17 loci implicated in adult-onset ulcerative colitis, highlighting the close pathogenetic relationship between early- and adult-onset IBD.

Abstract
BACKGROUND Folate is postulated to protect against cell injury and long-term risk of cancer. Folate deficiency has been shown to be associated with inflammatory bowel disease (IBD). However, folate concentrations are poorly delineated in children with IBD. OBJECTIVE The objective was to compare folate concentrations between children with newly diagnosed IBD and healthy controls. DESIGN Red blood cell folate (RBCF) and whole-blood folate (WBF) concentrations were measured in 78 children (mean age: 12.8 +/- 2.7 y): 22 patients with newly diagnosed untreated Crohn disease, 11 patients with ulcerative colitis, 4 patients with indeterminate colitis, and 41 controls. Vitamin supplementation and dietary intakes determined by food-frequency questionnaire were recorded for 20 IBD patients and 28 controls. RESULTS RBCF concentrations were 19.4% lower in controls (587.0 +/- 148.6 ng/mL) than in patients (728.7 +/- 185.8 ng/mL; P = 0.0004), and WBF concentrations were 11.1% lower in controls (218.2 +/- 49.7 ng/mL) than in patients (245.3 +/- 59.1 ng/mL; P = 0.031). Total folate intake was 18.8% higher in controls (444.7 +/- 266.7 microg/d) than in IBD patients (361.1 +/- 230.6 microg/d), but this difference was not statistically significant (P = 0.264). Folate intakes were below the Recommended Dietary Allowance (200-400 microg/d), adjusted for age and sex, in 35.4% of study subjects. CONCLUSIONS In contrast with previous evidence of folate deficiency in adult IBD patients, our data indicate higher folate concentrations in children with newly diagnosed untreated IBD than in controls. This finding was unexpected, especially in light of the higher dietary folate intakes and hematocrit values in children without IBD. The influence of IBD therapy on folate metabolism and the long-term clinical implications of high RBCF and WBF concentrations at the time of IBD diagnosis should be explored further.

Abstract
BACKGROUND Extraintestinal manifestations (EIMs) in pediatric patients with inflammatory bowel disease (IBD) are poorly characterized. We examined the prevalence of EIMs at diagnosis, subsequent incidence, and risk factors for EIMs. METHODS Data for 1649 patients from the PediIBD Consortium Registry, diagnosed with IBD before 18 years of age (1007 [61%] with Crohn's disease, 471 [29%] with ulcerative colitis, and 171 [10%] with indeterminate colitis), were analyzed using logistic regression, Kaplan-Meier, log rank tests, and Cox models. RESULTS EIMs were reported prior to IBD diagnosis in 97 of 1649 patients (6%). Older children at diagnosis had higher rates compared with younger children, and arthritis (26%) and aphthous stomatitis (21%) were most common. Among the 1552 patients without EIM at diagnosis, 290 developed at least 1 EIM. Kaplan-Meier estimates of cumulative incidence were 9% at 1 year, 19% at 5 years, and 29% at 15 years after diagnosis. Incidence did not differ by IBD type (P = 0.20), age at diagnosis (P = 0.22), or race/ethnicity (P = 0.24). Arthritis (17%) and osteopenia/osteoporosis (15%) were the most common EIMs after IBD diagnosis. CONCLUSIONS In our large cohort of pediatric IBD patients, 6% had at least 1 EIM before diagnosis of IBD. At least 1 EIM will develop in 29% within 15 years of diagnosis. The incidence of EIMs both before and after diagnosis of IBD differs by type of EIM and may be slightly higher in girls, but is independent of the type of IBD, age at diagnosis, and race/ethnicity.

Abstract
BACKGROUND & AIMS Few epidemiologic investigations characterize inflammatory bowel disease (IBD) in non-Caucasian children. Our study compared IBD characteristics between African Americans and non-African Americans enrolled in a multicenter pediatric IBD registry with endoscopic- and pathology-based diagnosis. METHODS The study retrieved data entered from January 2000 to October 2003 on children 1 to 17 years old, inclusive, followed by a consortium of academic and community US pediatric gastroenterology practices. Analyses examined racial/ethnic differences by comparing the proportions of African Americans and non-African Americans in the following categories: each diagnostic disease classification (any IBD, Crohn's disease, ulcerative colitis, indeterminate colitis); age group (<6 y, 6-12 y, or >12 y) at diagnosis or symptom onset; presence of extraintestinal manifestations, Z-scores for height and weight, immunomodulatory therapy, anatomic disease location, and abnormal hemoglobin, albumin, or sedimentation rate at diagnosis. RESULTS A total of 1406 patients had complete data, 138 (10%) of whom were African American. African Americans more often were older than 12 years of age at diagnosis (52% vs 37%; odds ratio [OR], 1.82; 95% confidence interval [95% CI], 1.28-2.59) and symptom onset (46% vs 30%; OR, 1.99; 95% CI, 1.40-2.84); had Crohn's disease (78% vs 59%; OR, 2.36; 95% CI, 1.56-3.58); and had a low hemoglobin level at diagnosis (39% vs 17%; OR, 3.15; 95% CI, 1.92-5.17). CONCLUSIONS IBD in African American children and adolescents presents more commonly with Crohn's disease and at older ages compared with non-African Americans. Racial/ethnic differences in the epidemiology of IBD, particularly Crohn's disease, among American youths require further investigation.

Abstract
OBJECTIVE To investigate the effect of human growth hormone (GH) injections on growth velocity in growth-impaired children with Crohn's disease (CD). STUDY DESIGN Ten children and adolescents (mean age, 12.6 +/- 4.5 years; 6 males) with CD and poor height growth were treated with open-label recombinant GH, 0.043 mg/kg/day administered via subcutaneous injection, for 1 year. Patients were retrospectively matched with untreated patients (3 comparisons per case) by race, age, sex, and baseline height. Primary endpoint was height velocity; secondary endpoints were disease activity, body composition, and bone density determined by dual-energy x-ray absorptiometry scan. RESULTS Mean height velocity increased by 5.33 +/- 3.40 (mean +/- standard deviation) cm/year in the GH-treated patients during the year of GH treatment, compared with 0.96 +/- 3.52 cm/year in the comparison group (P = .03). Height z-score increased by 0.76 +/- 0.38 in the treated group, compared with 0.16 +/- 0.40 in the comparison group (P < .01), and weight z-score increased by 0.81 +/- 0.89 in the treated group, compared with 0.00 +/- 0.57 in the comparison group (P < .01). Bone density revealed an increase of 0.31 +/- 0.33 in the lumbar spine z-score (P = .03 vs baseline). CONCLUSIONS GH treatment increases height velocity and may enhance bone mineralization in children with CD. A randomized controlled trial in a large cohort of children is needed to evaluate the ultimate impact of GH treatment.

Abstract
BACKGROUND The relationship between the age at diagnosis and disease course is poorly defined in children with Crohn's disease (CD). We examined the presentation and course of disease in patients 0-5 compared to 6-17 yr of age at diagnosis. METHODS We analyzed uniform data from 989 consecutive CD patients collected between January 2000 and November 2003, and stored in the Pediatric IBD Consortium Registry. The statistical tests account for the length of follow-up of each patient. RESULTS In total, 98 patients (9.9%) were of 0-5 yr of age at diagnosis. The mean follow-up time was 5.6 +/- 5.0 yr in the younger group and 3.3 +/- 2.8 yr in the older group (P < 0.001). Race/ethnicity differed by the age group (P= 0.015); a larger proportion of the younger group was Asian/Pacific Islander or Hispanic, and a larger proportion of the older group was African American. The initial classification as ulcerative colitis or indeterminate colitis was more common among the 0-5 yr of age group (P < 0.001). The 6-17 yr of age patients presented with more abdominal pain (P < 0.001), weight loss (P= 0.001), or fever (P= 0.07), while the 0-5 yr of age patients presented with more rectal bleeding (P= 0.008). The 6-17 yr of age patients were more likely to be treated with antibiotics (P < 0.001), 6-mercaptopurine/azathioprine (P < 0.001), infliximab (P= 0.001), or corticosteroids (P= 0.0006). The 6-17 yr of age patients had a higher cumulative incidence of treatment with 5-aminosalicylates (P= 0.009) or methotrexate (P= 0.04). The risk for developing an abscess (P= 0.001), a fistula (P= 0.02), a stricture (P= 0.05), or a perianal fissure (P= 0.06) was greater in the 6-17 yr of age patients. CONCLUSIONS The 6-17 yr of age patients with CD appear to have a more complicated disease course compared to 0-5 yr of age children. The 0-5 yr of age group may represent a unique disease phenotype and benefit from different approaches to management. Long-term prospective studies are required to validate these findings.

Abstract
BACKGROUND Differential immunoregulatory capabilities of probiotic Lactobacillus were explored in the context of pediatric Crohn's disease. Experimental strategies addressed molecular mechanisms of tumor necrosis factor (TNF) suppression in activated macrophages by transcriptional regulation. METHODS Secreted factors produced by probiotic Lactobacillus reuteri strains were harvested and tested with human monocytes and macrophages. Quantitative immunoassays and real-time reverse-transcriptase polymerase chain reaction (RT-PCR) were used to examine relative quantities of human cytokines and TNF mRNA, respectively, and reporter assays assessed transcriptional regulation of TNF by probiotics. DNA-protein macroarrays interrogated probiotic-mediated effects on transcription factor activation. Finally, enzyme-linked immunosorbent assays (ELISAs) and immunoblots examined the involvement of the specific transcription factor AP-1 and its components. RESULTS Probiotic L. reuteri strain ATCC PTA 6475 demonstrated the ability to potently suppress human TNF production by lipopolysaccharide-activated monocytes and primary monocyte-derived macrophages from children with Crohn's disease. Quantities of the chemokine MCP-1/CCL2 were also reduced by probiotic L. reuteri strain ATCC PTA 6475 in macrophages of children in remission. Quantitative real-time RT-PCR and luciferase reporter assays showed that transcriptional regulation of human TNF was a primary mechanism of probiotic-mediated immunomodulation. Probiotic L. reuteri suppressed TNF transcription by inhibiting activation of MAP kinase-regulated c-Jun and the transcription factor, AP-1. CONCLUSIONS Human TNF and MCP-1 suppression by probiotic L. reuteri was strain-dependent, and the activation of c-Jun and AP-1 represent primary targets for probiotic-mediated suppression of TNF transcription. This report emphasizes the clonal nature of immunoprobiosis and delineation of a specific immunomodulatory mechanism for probiotic strain selection in future inflammatory bowel disease-oriented clinical trials.

Abstract
OBJECTIVE The objective of this study was to determine gender differences in pediatric patients with Crohn disease. METHODS We conducted a retrospective cohort study of 989 consecutive pediatric patients (566 boys, 423 girls) who had Crohn disease (aged 0 to 17 years at diagnosis) by using the Pediatric IBD Consortium Registry. Uniform data were analyzed to compare the presentation and course of disease according to gender. RESULTS Median follow-up time was 2.8 years. Mean +/- SD age at diagnosis of inflammatory bowel disease (11.5 +/- 3.8 years) did not differ by gender. Compared with boys, girls had a higher prevalence of mouth sores at symptom onset and a higher prevalence of hypoalbuminemia at the time of diagnosis. Location of disease did not differ by gender. A higher proportion of girls had abnormal anti-outer membrane porin of Escherichia coli levels compared with boys. Girls were at increased risk for erythema nodosum/pyoderma gangrenosum and decreased risk for growth failure compared with boys. CONCLUSIONS Girls appear to have an overall more severe course of disease; however, boys are at increased risk for developing growth failure. Disease course and the impact of disease severity on growth according to gender in pediatric Crohn disease require prospective study.

Abstract
BACKGROUND The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition launched a provider and public education campaign in 2002 to raise awareness of gastroesophageal reflux disease (GERD). To determine the effectiveness of campaign messages, we conducted a knowledge, attitudes, and practice styles (KAPS) survey of pediatric providers. Understanding the spectrum of management styles of GERD in children is critical to achieve better health outcomes and reduce health care costs. MATERIALS AND METHODS The KAPS questionnaire was administered to 6000 randomly selected members of the American Academy of Pediatrics. RESULTS A total of 1245 members responded; 82% worked in a primary care setting and 18% in subspecialty practices. Overall, 66% of the members order diagnostic testing in routine practice, 54% start testing for GERD in neonates, and 38% start testing after 1 month of age. The most common tests ordered were barium esophagram (45%) and esophageal pH monitoring (37%). GERD treatment with acid suppression before ordering diagnostic testing was a choice of 82% of the respondents. However, 19% believed acid suppression was best achieved by H2 blockers. If acid suppression was indicated, then only 36% followed guideline recommendations for therapy duration and 52% followed guideline recommendations for dosing. Antireflux surgery was recommended only as a last resort by 92%. Overall, 69% of providers believed the amount of GERD-related information available was not enough. Respondents who were not aware of available GERD practice guidelines ranged from 74% to 92%. CONCLUSIONS Pediatric providers appear to frequently order diagnostic testing and treatment for GERD, yet knowledge about evidence-based GERD management among this random sample appeared limited. Moreover, a significant number of providers were not aware of different guideline publications.

Abstract
BACKGROUND & AIMS The cumulative incidence of surgery ranges from 40%-70% at 10 years from the time of diagnosis of Crohn's disease in adults. We retrospectively determined the cumulative incidence of and risk factors for surgery (intestinal resection) in pediatric patients with Crohn's disease. METHODS Uniform data from 989 consecutive Crohn's disease patients (age 0-17 years at diagnosis), collected from 6 different pediatric centers between January 2000 and November 2003 and stored in the Pediatric IBD Consortium Registry, were analyzed. RESULTS Median follow-up time was 2.8 years (range, 1 day to 16.7 years). One hundred twenty-eight patients underwent surgery. Kaplan-Meier survival estimates of the cumulative incidence of surgery were 17% at 5 years and 28% at 10 years from the diagnosis of inflammatory bowel disease. Univariate Cox proportional hazards models showed leukocytosis (2.85 [hazard ratio]; P = .02), hypoalbuminemia (3.41; P = .05), and anti-Saccharomyces cerevisiae antibody (ASCA) positivity (3.43; P = .05) were associated with increased risk for surgery. Multivariate Cox models showed female gender (1.49; P = .03), initial diagnosis of ulcerative colitis (3.63; P < .0001), poor growth at presentation (2.16; P = .007), and abscess (1.90; P = .009), fistula (2.30; P = .0005), or stricture (3.41; P < .0001) development were associated with increased risk for surgery. Age 3-5 years (0.26; P = .01) or 6-12 years (0.62; P = .01) at diagnosis, fever at presentation (0.50; P = .03), and treatment with infliximab (0.36; P = .0005) or 5-aminosalicylic acid (0.44; P < .0001) were associated with decreased risk for surgery. CONCLUSIONS Risk stratification during the course of Crohn's disease in pediatric patients will help to guide therapy that may improve the natural history of disease and decrease the need for surgery.

Abstract
Successful clinical trials in inflammatory bowel disease are based on precise definitions of study populations, standardized and well-defined interventions, reliable indices of disease activity, and clearly stipulated outcome measures. Interpretation of research results is often complicated by the differentiation of goals of therapy (remission induction and maintenance, quality of life) and the multitude of patient subsets. Choosing the correct patient subtype to enroll in a clinical trial is critical to the results of a study, its conclusions, and its applicability to the clinical setting. Validated, easy-to-use disease activity indices allow interpretation of results across trials. The use of biomarkers as surrogate clinical endpoints provides reproducibility, ease of statistical handling as a continuous variable, and consistent measurement of response to treatment. Despite these potential advantages, biomarkers of disease activity lack specificity and will need to be validated against clinically meaningful outcomes. Careful subject selection, standardization of disease activity indices, and precise outcome measurement are the keys to continued improvement of the inflammatory bowel disease research process.

Abstract
Probiotics are widely used by patients with Crohn's disease (CD) in an attempt to improve their health, but few controlled studies have been done to evaluate the efficacy of these therapies. We conducted a randomized, placebo-controlled trial of the probiotic Lactobacillus rhamnosus strain GG (LGG) to see if the addition of LGG to standard therapy prolonged remission in children with CD. Concomitant medications allowed in the study included aminosalicylates, 6-mercaptopurine, azathioprine, and low-dose alternate day corticosteroids. Seventy-five children (age range, 5-21 yr) with CD in remission were randomized to either LGG (n=39) or placebo (n=36) and followed for up to 2 years. The median time to relapse was 9.8 months in the LGG group and 11.0 months in the placebo group (P=0.24); 31% (12/39) of patients in the LGG group developed a relapse compared with 6/36 (17%) of the placebo group (P=0.18). The LGG was well tolerated, with a side effect profile comparable with placebo. This study suggests that LGG does not prolong time to relapse in children with CD when given as an adjunct to standard therapy.

Abstract
OBJECTIVES The objectives of this study were to evaluate the safety, pharmacokinetics, and immunogenicity of CDP571 in pediatric patients with Crohn's disease. METHODS A single dose of CDP571, 10 mg/kg, was administered by infusion to pediatric patients (aged 6-17 years) with Crohn's disease in a 12-week open-label study. Adverse events were monitored during infusion and throughout the study. Plasma concentrations of CDP571 and standard clinical and laboratory values were assessed. Changes in disease activity were monitored using the Pediatric Crohn's Disease Activity Index (PCDAI). RESULTS Twenty patients were enrolled and stratified by age: 6 to 13 (n = 9) and 14 to 17 years (n = 11). Fourteen patients experienced adverse events, which were mainly mild or moderate in intensity. The plasma concentration profile was consistent with a half-life of approximately 2 weeks. At Week 4, 4 patients in the 6- to 13-year-old group and 2 patients in the 14- to 17-year-old group had detectable anti-CDP571 antibodies. By Week 2, 7 patients in the 6- to 13-year-old group and 6 patients in the 14- to 17-year-old group had responded to treatment (reduction in PCDAI score >10 points). CONCLUSION In conclusion, CDP571 was well tolerated among pediatric patients with Crohn's disease.

Abstract
Inflammatory bowel diseases (Crohn's disease and ulcerative colitis) primarily affect young adults, but in 15%-25% of cases, the initial disease starts in childhood. Many aspects of inflammatory bowel disease, including initial evaluation, nutritional support, medical and surgical intervention, and the direction of future research, are encountered in both adult and pediatric patients. However, it is important to delineate issues specific to pediatric patients, especially growth velocity impairment, derangements in and treatment of abnormal bone mineralization, and transitional care issues; the lack of extensive randomized, controlled pediatric therapeutic trials is also a concern. This article reviews the epidemiology of pediatric inflammatory bowel disease incidence and prevalence worldwide, clinical issues (including impairments of growth velocity and bone density), diagnostic and therapeutic interventions, and psychosocial issues unique to pediatric patients. Future research directions defined by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and opportunities provided by existing pediatric research databases are highlighted.

Abstract
OBJECTIVE To evaluate the efficacy of oral tacrolimus as an induction agent in steroid-refractory severe colitis. STUDY DESIGN Open-label, multicenter trial of oral tacrolimus in patients with severe colitis. Patients not responding to conventional therapy received tacrolimus, 0.1 mg/kg/dose given twice a day, and the dosage was adjusted to achieve blood levels between 10 and 15 ng/mL. Response was defined as improvement in a number of clinical parameters (including abdominal pain, diarrhea, rectal bleeding, and cessation of transfusions). Patients who responded by 14 days continued to receive tacrolimus, and 6-mercaptopurine or azathioprine was added as a steroid-sparing agent 4 to 6 weeks after the tacrolimus was instituted. RESULTS Fourteen patients were enrolled in the study. One patient elected to withdraw after 48 hours. Of the 13 remaining, 9 (69%) responded and were discharged. Tacrolimus was continued for 2 to 3 months in the responders, except for 1 patient who was given tacrolimus for 11 months. After 1 year of follow-up, only 5 (38%) patients were receiving maintenance therapy; the other 4 responders had undergone colectomy. CONCLUSION Although tacrolimus is effective induction therapy for severe ulcerative or Crohn's colitis, fewer than 50% of patients treated will successfully achieve a long-term remission.

Abstract
Defining and measuring quality of life is a relatively new dimension of health care for many clinicians. The traditional method of evaluating clinical status and response to treatment has been to look at disease-specific symptoms, global assessments (e.g., impressions of the good, better, or worse condition of a patient), days missed at school, and a variety of disease activity scores. These impressions and techniques may or may not reflect how patients are functioning day to day and how they feel about the illness. To address these issues, health-related quality of life questionnaires have been developed to measure the functional effect of an illness and its treatment on a patient, as perceived by the patient. There are four broad domains that are considered part of a health-related quality-of-life questionnaire: 1) physical and occupational function, 2) psychologic state, 3) social interaction, and 4) somatic sensation. In the case of children, the perception of parents or caretakers may be added to complete the picture. Significant social and psychiatric problems have been described in children with IBD, including absenteeism from school, depression, suicide, and major disruption of family patterns. To understand fully the impact of inflammatory bowel disease and its treatment on patient and family function requires one or more quality-of-life instruments that are sensitive to the full range of symptoms, growth and development, and response (including side effects) to many new therapies.

Abstract
OBJECTIVE To report a significant improvement of direct hyperbilirubinemia values, in an infant with cholestasis secondary to erythroblastosis fetalis, after treatment with ursodeoxycholic acid (UDCA). STUDY DESIGN Case report. RESULTS A full term infant, with total and direct bilirubin values of 26 mg/dl (445 micromol/l) and 24.5 mg/dl (419 micromol/l), respectively, on the third day of life, had total and direct bilirubin values of 8.2 mg/dl (140 micromol/l) and 6.9 mg/dl (118 micromol/l), respectively, after 2 days of treatment with UDCA. Because the natural course of this cholestasis takes several weeks to resolve, the observed improvement is highly suggestive of a direct effect of UDCA on the disease course. CONCLUSION This treatment may add a new therapeutic option to the limited measures available for this condition, although further studies regarding safety and its mechanism of action are needed before it can be routinely recommended.

Abstract
Limy bile syndrome (LBS) is a rare condition in which a radiopaque gallbladder and/or bile ducts are noted on plain roentgenograms. LBS is caused by calcium carbonate precipitation in the bile and is usually associated with distal biliary tract obstruction. The etiology of limy bile syndrome is unclear; however, it may be a long-term complication of total parenteral nutrition.

Abstract
The safety and efficacy of olsalazine sodium was compared to sulfasalazine over 3 months in a multicenter, randomized, double-blind study of 56 children with mild to moderate ulcerative colitis. Twenty-eight children received 30 mg/kg/day of olsalazine (maximum, 2 g/day) and 28 received 60 mg/kg/day of sulfasalazine (maximum, 4 g/day). Side effects were frequent in both groups. Eleven of 28 patients (39%) on olsalazine reported headache, nausea, vomiting, rash, pruritus, increased diarrhea, and/or fever. Thirteen of 28 on sulfasalazine (46%) reported similar side effects and/or neutropenia, and four patients had the drug stopped because of an adverse reaction. After 3 months, 11 of 28 (39%) on olsalazine were asymptomatic or clinically improved, compared to 22 of 28 (79%) on sulfasalazine (p = 0.006). In addition, 10 of 28 patients on olsalazine versus one on sulfasalazine required prednisone because of lack of response or worsening of colitis (p = 0.005). The dose of olsalazine used in this clinical trial was thought to be equivalent to a standard dose of sulfasalazine, but fewer patients on olsalazine improved and a greater number had progression of symptoms when compared to sulfasalazine. Although side effects were slightly less frequent for olsalazine, the number of patients was too small to detect a clinically significant difference.

Abstract
The Pediatric Crohn's Disease Activity Index (PCDAI) has been proposed as a simple instrument to aid in the classification of patients by disease severity. The PCDAI includes subjective patient reporting of symptoms, physical examination, nutritional parameters, and several common laboratory tests (hematocrit, erythrocyte sedimentation rate, albumin). In this report we examine the relationship of each of the laboratory parameters to the PCDAI, as well as to a modified Harvey-Bradshaw Index score and physician global assessment of disease activity. Data were gathered from the clinical and laboratory observations from 133 children and adolescents at 12 pediatric gastroenterology centers in North America. A statistically significant relationship (p less than 0.05) was noted between each of the laboratory tests and the PCDAI for patients with either disease limited to the small bowel or in those with colonic involvement. For patients with disease limited to the small bowel, a statistically significant (p less than 0.05) relationship was also noted between the three laboratory parameters and the modified Harvey-Bradshaw Index and global assessment. For patients with large-bowel involvement, the erythrocyte sedimentation rate was statistically related to the modified Harvey-Bradshaw Index and global assessment (p less than 0.01), as was hematocrit to global assessment (p less than 0.01). Although the laboratory parameters used in the PCDAI appear to generally reflect disease activity in most patients, no single laboratory test is adequate to reflect disease activity in all patients. Future work will need to identify additional laboratory measures to reflect the inflammatory process and serve as important adjuncts in the assessment of disease activity.

Abstract
Orthotopic liver transplantation (OLT) represents the only therapeutic option for many patients with end-stage liver disease as well as many inborn genetic errors of hepatic metabolism. Despite dramatic progress in methods for OLT, the utilization of this procedure is limited by its considerable morbidity and mortality, by a chronic shortage of organs for transplant, and by difficulty arranging funding for many patients. Many children with fulminant hepatic failure do not receive OLT because this technology is unavailable or unaffordable. Hepatocellular transplantation (HCT), in which isolated, heterologous hepatocytes from a donor liver would be infused into the diseased organ in order to provide essential hepatic functions, could provide a much needed therapeutic alternative to OLT in the treatment of some causes of hepatic insufficiency. Experiments in animals have demonstrated that several genetic deficiencies of hepatic metabolism as well as experimental induced hepatic failure in animals can be reversed by HCT. Despite this experience, HCT has never been attempted in human subjects. This protocol represents the first proposed clinical trial of HCT. We are proposing a clinical trial in which HCT would be attempted as a therapeutic intervention in children with acute hepatic failure who have no other medical or surgical options. This proposal is intended to establish surgical methods for HCT and to evaluate the feasibility of this procedure for treating hepatic disease in humans. It is our expectation that HCT may provide short-term support for patients awaiting organ availability, a "bridge to recovery" allowing patients with fulminant hepatic failure to recover, or a long-term repopulation of the patient's liver with healthy donor cells. One of the major limitations of many animal studies in HCT is that, since the donor hepatocytes are often indistinguishable from those of the host, it has often been difficult to demonstrate a clear correlation between engraftment and the therapeutic effect. In order to verify engraftment independent of the therapeutic response, we propose to "mark" the donor hepatocytes by transducing these cells with a recombinant retroviral vector (LNL6) carrying a marker gene (NEO-R, neomycin phosphoribosyl transferase). The presence of this marker will enhance the ability to identify transplanted cells in the host using assays for the NEO-R gene or transcribed NEO-R mRNA. The LNL6 vector has been approved for human use and has been used as a marker gene for transplanted cells in human subjects without any reported adverse effects. We would like to emphasize that this is a proposal with therapeutic intent.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
Clinical and laboratory observations of 133 children and adolescents with Crohn's disease were used to validate an index of severity of illness previously developed by a group of senior pediatric gastroenterologists at a research forum in April 1990. This pediatric Crohn's disease activity index (PCDAI) included (a) subjective reporting of the degree of abdominal pain, stool pattern, and general well-being; (b) presence of extraintestinal manifestations, such as fever, arthritis, rash, and uveitis; (c) physical examination findings; (d) weight and height; and (e) hematocrit, erythrocyte sedimentation rate, and serum albumin. Independent evaluation of each patient by two physician-observers was performed at the time of a visit, and each physician completed a PCDAI index and a modified Harvey-Bradshaw index and made a "global assessment" of disease activity as none, mild, moderate, or severe. Excellent interobserver agreement was noted for the PCDAI, modified Harvey-Bradshaw index, and global assessment. There was a strong correlation between global assessment and both the PCDAI or modified Harvey-Bradshaw. Increasing PCDAI scores were noted with increasing disease severity, and significant differences in scores were noted between the severity groups. We propose that the PCDAI could be used in multicenter projects to facilitate patient stratification by disease severity and that longitudinal PCDAI scores might provide a numerical measure of response to therapeutic regimens.

Abstract
This case describes a patient with cholesteryl ester storage disease who underwent liver transplantation for progressive cirrhosis, portal hypertension, ascites, and uncontrollable gastrointestinal bleeding. Four and one-half years posttransplant, her growth improved, cholesterol levels have returned to normal, and she is clinically well except for mild hypersplenism and an elevated blood urea nitrogen (BUN) and creatinine. Serum triglycerides remain elevated, but there have been no signs of progressive renal, intestinal, vascular, or pulmonary disease.

Abstract
An epidemiological study was conducted to estimate the proportion of infants on total parenteral nutrition (TPN) who developed cholestasis and to identify risk factors associated with the development of this disease. Data were abstracted from medical records of 624 infants less than or equal to 30 days of age who were treated with TPN. A case of TPN-related cholestasis was defined as an infant whose serum level of direct bilirubin was greater than or equal to 1.5 mg/dl subsequent to initiation of TPN. Risk factors were assessed using multiple logistic regression analysis. Forty-six of 624 infants in the cohort (7.4%) were classified as having TPN-related cholestasis. The multivariable analysis indicated that cholestasis was associated with intracranial hemorrhage, patent ductus arteriosus, sepsis and gastrointestinal conditions that require surgery. Two distinct processes appear to have occurred: in infants who experienced patent ductus arteriosus or intracranial hemorrhage (conditions associated with hypoxia) where TPN may be the necessary trigger for the development of cholestasis, and in infants with gastrointestinal conditions requiring surgery or sepsis, where cholestasis may develop with or without parenteral infusions.

Abstract
The vascular lesions, angiomas, and arteriovenous malformations are known to be associated with a number of complications. These lesions, when present in the liver, may precipitate heart failure in infants. Recent reports suggest that although the prognosis is good for the majority of infants who survive the neonatal period, the lesions are capable of causing portal hypertension later in life. We have encountered three patients whose vascular lesions were in continuity with the portal circulation who subsequently went on to develop portal hypertension. One patient had angiomas of the liver, one splenic and colonic angiomas, and the third had diffuse arteriovenous malformations of the intestine. Data are presented and literature is reviewed, which suggest that any vascular lesion that is capable of substantially increasing portal blood flow may lead to the development of portal hypertension. The treatment of such lesions should be aggressive. If surgical management is not possible, alternative treatments such as embolization should be attempted early in order to increase the chance for successful therapy.

Abstract
Two patients with gastrointestinal tract abnormalities were discovered to have significant defects in both humoral and cellular immunity. Patient 1, a 4-year-old girl with suspected food allergy, failure to thrive, and chronic diarrhea, exhibited a decreased serum IgG immunoglobulin level, decreased numbers of peripheral blood T lymphocytes (erythrocyte rosettes), decreased numbers of T-lymphocyte subpopulations (T3+, T4+), decreased responses of lymphocytes to common mitogens, and absent in vivo responses to delayed hypersensitivity skin test antigens. Patient 2, a 3-year-old girl with chronic anemia, presented with immunological abnormalities similar to those of patient 1. On investigation, both patients were found to have significant structural abnormalities of the gastrointestinal tract. Patient 1 had a malrotation of the small bowel, while patient 2 had a cavernous hemangioma of the mid-jejunum. Following surgical correction of the gastrointestinal abnormalities, there was improvement in all immunologic values. By ten to 18 months after surgery, both patients demonstrated normal immunological function. Thus, anatomic lesions of the gastrointestinal tract that mimic more common childhood disorders, such as food allergy and anemia, may produce serious states of secondary immunodeficiency.

Abstract
Presenting characteristics, long-term outcome, and techniques used in the diagnosis of 143 infants with suspected biliary obstruction are reviewed. Sixty-nine patients had surgically confirmed extrahepatic disease and 74 had intrahepatic disorders. A disproportionate number of infants with intrahepatic disease were boys (p = 0.013), low birthweight (p = 0.001), or had siblings with liver disease (p = 0.017). An initial total bilirubin of 20 mg/dl or greater was rare except in the intrahepatic disease category of neonatal hepatitis of known cause (p = 0.006). The initial percutaneous liver biopsy correctly predicted the ultimate diagnosis in 94 percent of all 143 patients. A methodological outline to diagnosis is presented, emphasizing early recognition of symptoms and careful follow-up with hepatobiliary imaging, liver biopsy, and surgical exploration, if required, until definitive diagnosis is made. This approach has aided us in reducing the age of diagnosis of biliary atresia from 12.8 +/- SD 7.3 weeks during the period 1971 through 1979 to 6.8 +/- SD 2.6 weeks from 1980 to 1982 (p = 0.0015). Eighteen-month survival has improved from 25 to 60 percent.

Abstract
When conventional treatment with upright positioning and thickened feedings fails to control vomiting associated with gastroesophageal reflux (GER) of infancy, malnutrition and growth failure may result. If this occurs, fundoplication is usually recommended. In this study, 12 infants with growth failure associated with GER were given a trial of short-term (11.1 +/- SE 1.6 days) continuous-drip nasogastric (NG) feedings prior to surgical referral. Five of 10 infants for whom long-term follow-up (3-12 months) was obtained showed immediate weight gain, cessation of vomiting, and long-term resolution of growth failure without the need for surgery. All infants who had a favorable long-term response showed evidence of catch-up growth during the first 7 days of NG feeding. Infants who did not begin catch-up growth during the first 7 days did not benefit from longer periods (up to 21 days) of NG feeding. Poor response to NG feedings was associated with the presence of other medical problems (p = 0.024), including chronic pulmonary disease, malabsorption, cerebral palsy, and laryngomalacia. Four infants who did require fundoplication still showed no improvement in growth 2-6 months after surgery. In infants with GER and growth failure without other complicating disorders, a 7-10-day course of NG feeding may improve nutrition and bring about a permanent resolution of vomiting.

Abstract
Seven patients with cystic fibrosis who had complications of gastroesophageal reflux including abdominal pain, peptic esophagitis, upper gastrointestinal hemorrhage, and esophageal stricture are described. We believe that these are gastrointestinal complications of CF and that they may be responsible for significant morbidity. The mechanical influence of a depressed diaphragm caused by hyperinflation, along with increased abdominal pressure with chronic coughing, may contribute to GER in CF. Early detection and treatment are important not only to prevent esophageal complications but also to increase the quality of life by relief of pain and by avoiding the resultant decrease in appetite, which can contribute to malnutrition.

Abstract
Between January 1978 and September 1979, 29 children with acute leukemia in complete continuous remission for three or more years were examined for evidence of occult extramedullary disease immediately prior to discontinuation of chemotherapy. Bilateral open wedge testicular biopsy demonstrated the presence of bilateral leukemic infiltrates in 2/13 boys. Gallium scans prior to biopsy had identified unilateral infiltration in an enlarged testis in one patient but failed to identify microscopic disease in the opposite testis or in the testes of the second patient. Percutaneous kidney and liver biopsies, pelvic ultrasonography, intravenous pyelogram, skeletal survey, cranial computed axial tomography scan, electroencephalography, and ophthalmologic examinations failed to demonstrate evidence of occult disease. Except for testicular biopsy, this study does not support extensive clinical or invasive procedures to identify extramedullary disease prior to discontinuation of chemotherapy.
