Endoscopy in Pediatric Inflammatory Bowel Disease: A Position Paper on Behalf of the Porto IBD Group of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition

Endoscopy is a central tool for the evaluation and management of inflammatory bowel disease (IBD). In the last few decades, gastrointestinal (GI) endoscopy has undergone significant technological developments including availability of pediatric-size equipment, enabling comprehensive investigation of the GI tract in children. Simultaneously, professional organization of GI experts have developed guidelines and training programs in pediatric GI endoscopy. This prompted the Porto Group on Pediatric IBD of the European Society for Pediatric Gastroenterology, Hepatology and Nutrition to develop updated guidelines on the role of GI endoscopy in pediatric IBD, specifically taking into considerations of recent advances in the diagnosis, disease stratification, and novel therapeutic targets in these patients.

Improved Medical Treatment and Surgical Surveillance of Children and Adolescents with Ulcerative Colitis in the United Kingdom

Background

Pediatric ulcerative colitis (UC) presents at an earlier age and increasing prevalence. Our aim was to examine morbidity, steroid sparing strategies, and surgical outcome in children with active UC.

Methods

A national prospective audit was conducted for the inpatient period of all children with UC for medical or surgical treatment in the United Kingdom (UK) over 1 year. Thirty-two participating centers recruited 224 children in 298 admissions, comparisons over 6 years were made with previous audits.

Results

Over 6 years, recording of Paediatric Ulcerative Colitis Activity Index (PUCAI) score (median 65)(23% to 55%, P < 0.001), guidelines for acute severe colitis (43% to 77%, P < 0.04), and ileal pouch surgery registration (4% to 56%, P < 0.001) have increased. Corticosteroids were given in 183/298 episodes (61%) with 61/183 (33%) not responding and requiring second line therapy or surgery. Of those treated with anti-TNFalpha (16/61, 26%), 3/16 (18.8%) failed to respond and required colectomy. Prescription of rescue therapy (26% to 49%, P = 0.04) and proportion of anti-TNFalpha (20% to 53%, P = 0.03) had increased, colectomy rate (23.7% to 15%) was not significantly reduced (P = 0.5). Subtotal colectomy was the most common surgery performed (n = 40), and surgical complications from all procedures occurred in 33%. In 215/224 (96%) iron deficiency anemia was detected and in 51% treated, orally (50.2%) or intravenously (49.8%).

Conclusions

A third of children were not responsive to steroids, and a quarter of these were treated with anti-TNFalpha. Colectomy was required in 41/298 (13.7%) of all admissions. Our national audit program indicates effectiveness of actions taken to reduce steroid dependency, surgery, and iron deficiency. 10.1093/ibd/izy042_video1izy042.video15769503407001.

Cyclic vomiting syndrome in adults

Cyclic vomiting syndrome (CVS) was initially described in children but can occur in all age groups. Cyclic vomiting syndrome is increasingly recognized in adults. However, the lack of awareness of CVS in adults has led to small numbers of diagnosed patients and a paucity of published data on the causes, diagnosis and management of CVS in adults. This article is a state-of-knowledge overview on CVS in adults and is intended to provide a framework for management and further investigations into CVS in adults.

Constipation in childhood: a multidisciplinary approach to management in the community

Three per cent of children in the community may be affected by chronic constipation. Causes of constipation may be organic or functional: the cornerstone of management is thorough interview and physical examination to identify appropriate investigations, identify causes and decide on management. Whatever the cause, faecal impaction must be managed as the first phase of treatment using appropriate medications. Other strategies may include increasing the fibre content of the child's meals and increasing fluid intake. Getting into a regular toilet habit helps prevent constipation and a structured toileting programme promotes the resumption of faecal continence.

The seroprevalence of Helicobacter pylori in a referral population of children in the United States

OBJECTIVES

The purpose of this study was to determine the prevalence of serum antibodies directed against Helicobacter pylori (H. pylori) in children referred to children's hospitals or medical centers throughout the United States.

METHODS

This multisite cross-sectional prospective study involved 992 children from 12 states using a validated anti-H. pylori IgG enzyme immunoassay. The children were recruited into two groups: those without any GI complaints (non-GI referral, n = 619) and those who were referred for endoscopy because of abdominal pain (GI referral, n = 373).

RESULTS

GI referral children had a higher rate of seropositivity (22.5%) than non-GI referral children (14.1%) from the same geographic regions. In both groups, older children were more likely to be seropositive for H. pylori, as were nonwhite children and those with lower socioeconomic status. H. pylori seropositivity rates were higher in GI referral children with four or more household members (relative risk [RR] = 1.47; CI 1.01-2.14). Multivariate analysis controlling for age, ethnicity, and household income, showed that presence of GI symptoms were associated with a nearly 2-fold risk for H. pylori seropositivity (odds ratio = 1.77, CI 1.27-2.47). Epigastric pain (RR = 2.21; CI = 1.33-3.66) and having three or more episodes of abdominal pain in the last 3 months (RR = 0.59, CI = 0.35-0.99) were the only specific symptoms significantly associated with H. pylori seropositivity.

CONCLUSIONS

The H. pylori seropositivity rate of GI referral children with symptoms of abdominal pain was significantly higher. H. pylori infection in early childhood was found to be associated primarily with the child's household size and socioeconomic status.

Treatment of Helicobacter pylori gastritis improves dyspeptic symptoms in children

BACKGROUND

In adults, the treatment of Helicobacter pylori infection is only recommended for patients with active gastric or duodenal ulcers. It is not known whether similar guidelines can be applied to children because the prevalence of peptic ulcer disease in childhood is estimated to be much lower than in adults. The purpose of this study was to determine whether treatment of H. pylori gastritis would improve symptoms of dyspepsia in children.

METHODS

Sixteen patients (5 boys, 11 girls) aged 14 +/- 1.2 years who had symptoms of dyspepsia were evaluated using upper gastrointestinal endoscopy with biopsies to establish the diagnosis of H. pylori gastritis. They were treated for 2 weeks with clarithromycin, amoxicillin, and a proton pump inhibitor. Dyspepsia symptoms were evaluated by a questionnaire before and after treatment of the infection. The effect of H. pylori treatment on the total symptom score was analyzed with use of the Student t test. Values are presented as mean +/- SEM.

RESULTS

All patients had antral nodularity and chronic active gastritis with spiral-shaped organisms but no evidence of peptic ulcer disease. Mean total symptom score decreased significantly at 2 to 4 weeks after treatment (12.6 +/- 0.9 vs. 2.1 +/- 0.5 P < 0.001), and it remained low (2.9 +/- 0.7) at follow-up 9.7 +/- 1.4 months (range, 2-24 months later).

CONCLUSION

These results suggest that the treatment of H. pylori gastritis can improve dyspeptic symptoms in children.
