Esophageal Remodeling Correlates With Eating Behaviors in Pediatric Eosinophilic Esophagitis.

INTRODUCTION: There are limited data characterizing eating habits among pediatric patients with eosinophilic esophagitis (EoE). We compared eating behaviors in pediatric patients with EoE with healthy controls and assessed the degree of correlation with symptomatology, endoscopic and histologic findings, and esophageal distensibility. METHODS: We conducted a prospective, observational study where subjects consumed 4 food textures (puree, soft solid, chewable, and hard solid) and were scored for eating behaviors including number of chews per bite, sips of fluid per food, and consumption time. Symptomatic, endoscopic, histologic, and esophageal distensibility data were collected for case subjects. RESULTS: Twenty-seven case subjects and 25 healthy controls were enrolled in our study (mean age 11.0 years, 63.5% male). Compared with healthy controls, pediatric patients with EoE demonstrated more chews per bite with soft solid (13.6 vs 9.1, P = 0.031), chewable (14.7 vs 10.7, P = 0.047), and hard solid foods (19.0 vs 12.8, P = 0.037). Patients with EoE also demonstrated increased consumption time with soft solid (94.7 vs 58.3 seconds, P = 0.002), chewable (90.0 vs 65.1 seconds, P = 0.005), and hard solid foods (114.1 vs 76.4 seconds, P = 0.034) when compared with healthy controls. Subgroup analysis based on disease status showed no statistically significant differences in eating behaviors between active and inactive EoE. Total endoscopic reference score positively correlated with consumption time ( r = 0.53, P = 0.008) and number of chews ( r = 0.45, P = 0.027) for chewable foods and with number of chews ( r = 0.44, P = 0.043) for hard solid foods. Increased consumption time correlated with increased eosinophil count ( r = 0.42, P = 0.050) and decreased esophageal distensibility ( r = -0.82, P < 0.0001). DISCUSSION: Altered eating behaviors including increased chewing and increased consumption time can be seen in pediatric patients with EoE, can persist despite histologic remission, and may be driven by changes in esophageal distensibility.

Trajectory of body mass index and obesity in children with Crohn's disease compared to healthy children.

BACKGROUND: There is increasing recognition that children with Crohn's Disease (CD) can develop obesity. METHODS: Using the RISK Study, an inception cohort of pediatric CD participants, and Bone Mineral Density in Childhood Study (BMDCS), a longitudinal cohort of healthy children, multivariable linear mixed effects, generalized linear mixed effects, and logistic regression models were used to evaluate factors associated with change in body mass index z-score (BMIZ), obesity, and excessive weight gain, respectively. RESULTS: 1029 CD participants (625 exposed to antitumor necrosis factor (anti-TNF) therapy) and 1880 healthy children were included. Change in BMIZ was higher in CD exposed to anti-TNF as compared to CD unexposed to anti-TNF and the healthy reference group. Sex, age, baseline BMIZ, C-reactive protein, anti-TNF, and steroids were associated with changes in BMIZ in CD. CD exposed (odds ratio [OR] 4.81, confidence interval [CI] 4.00-5.78) and unexposed (OR 3.14, CI 2.62-3.76) had a greater likelihood of becoming obese versus the healthy reference group. While the prevalence of obesity was higher at baseline in the healthy reference group (21.3%) versus CD participants (8.5% exposed vs. 11.1% unexposed), rates of obesity were similar by the end of follow-up (21.4% healthy vs. 20.3% exposed vs. 22.5% unexposed). Anti-TNF therapy was an independent risk factor for the development of obesity and excessive weight gain in CD participants. CONCLUSIONS: Patients with CD have dynamic changes in BMIZ over time, and while for most, this is restorative, for some, this can lead to obesity and excessive weight gain. It is important to understand the factors that may lead to these changes, including anti-TNF therapy. Counseling of patients and early lifestyle intervention may be necessary.

A prospective, controlled multisite trial of yoga in pediatric inflammatory bowel disease.

AIM: To investigate whether a structured yoga program improves health-related quality of life (HRQOL) and self-efficacy in pediatric patients receiving care for inflammatory bowel disease (IBD). METHODS: IBD patients who were 10-17 years old participated in a 12 week, in-person yoga intervention at two clinical sites. Outcomes were measured at time of consent (T0), start of yoga (T1), and completion of yoga (T2) and 3 months after yoga completion (T3) using the IMPACT-III, Pediatric Quality of Life Inventory (PedsQL), and General Self Efficacy (GSE) scales. RESULTS: Seventy-eight patients were enrolled. Fifty-six patients completed nine or more classes. 73.2% had Crohn's disease and 26.8% ulcerative colitis or IBD-unclassified. A significant increase in IMPACT-III was seen from T1 to T3 (mean change of 5.22, SD = 14.33, p = 0.010), in the PedsQL (mean change = 2.3, SD = 10.24, p = 0.050), and GSE (mean change = 1, SD = 3.60, p = 0.046). 85.2% of patients reported yoga helped them to control stress. Long-term data was available for 47 subjects with 31.9% (n = 15) continuing to practice yoga one to 3 years after study completion. CONCLUSION: This structured 12-week yoga program showed significant improvements in HRQOL and general self-efficacy, particularly 3 months after classes were concluded suggesting that yoga's benefits may persist. Yoga is a safe and effective adjunct to standard medical care to improve QOL and self-efficacy in youth with IBD.

Clinical characterization of Co-morbid autoimmune disease and eating disorders: a retrospective chart review.

Research suggests a link between autoimmune illnesses (AI) and eating disorders (ED). We retrospectively reviewed charts of adolescent patients presenting for eating disorder treatment. We compared the presentation and treatment course for those with an ED and comorbid AI [with (GI-AI, N = 59) or without (non-GI, N = 21) gastrointestinal inflammation] with matched ED-only cases. The sample was overwhelmingly female, with an average age of 15.40. Weight gain trajectories differed across groups, with similar rates of weight gain between controls and non GI-AI cases and with a lower rate of weight gain for individuals with comorbid GI-AI. Over half (56%) of patients reported an AI diagnosis prior to ED; 38% reported an AI diagnosis following ED, and 6% reported ED and AI simultaneous diagnosis. On presentation, ED-only controls had higher rates of comorbid anxiety than cases in either AI group, while those with non-GI AI were more likely to report depression. Mean total GI symptoms, % goal weight at presentation, vital sign instability, and markers of refeeding syndrome did not differ across groups. Health care professionals treating patients with either condition should have a low threshold for asking additional questions to identify the presence of the other condition.
