ABSTRACT

INTRODUCTION AND AIMS: The ingestion of foreign bodies, such as magnets, is a potentially lethal accident that affects children and is associated with bleeding and gastrointestinal perforation, as well as death. There are no Latin American reports in the literature on cases of magnet ingestion in children. Our aim was to establish whether said ingestion has been seen by pediatric endoscopists and gastroenterologists in Latin America, to determine the scope of that potential threat in their patient populations. MATERIALS AND METHODS: We collected data regarding endoscopies performed on children in Latin America, within the time frame of 2017-2019, through questionnaires that were distributed to pediatric endoscopists at the 2nd World Congress of Gastrointestinal Endoscopy (ENDO 2020). The questionnaires provided information on foreign body location, the presence and number of ingested magnets, and the description of complications and surgical interventions. RESULTS: Our cohort from 12 Latin American countries reported 2,363 endoscopies due to foreign body ingestion, 25 (1.05%) of which were the result of having swallowed one or more magnets. Mean patient age was 5.14 years (SD 2.5) and 10 (40%) of the cases were girls. Three (12%) of the patients presented with severe complications and 2 (8%) cases required surgery. CONCLUSIONS: Our preliminary study suggests that the ingestion of magnets is not common in Latin American countries, but said cases are frequently associated with complications. Constant monitoring of the incidence of such cases is extremely important, so that through education and awareness of those events, life-threatening complications in children can be prevented.

ABSTRACT

The gut-brain axis has recently emerged as a key modulator of human health and the intestinal microbiome has a well-recognised pivotal role in this strong connection. The aim of this narrative review is to update and summarise the effect and clinical applicability of probiotics in paediatric neurogastroenterology. The Cochrane Database and PubMed were searched using keywords relating to different subtypes of functional gastrointestinal disorders (FGIDs) and their symptoms, those relating to the CNS and related neurological or behavioural dysfunction as well as 'probiotic' OR 'probiotics'. Included papers were limited to those including children (aged 0-18 years) and using English language. Although significant effects of specific strains have been reported in infants with FGIDs, heterogeneity amongst the studies (different products and concentrations used and FGID subtypes), has limited the ability to draw an overall conclusion on the clinical value of probiotics. According to different meta-analyses of randomised controlled trials, the use of Lactobacillus reuteri (DSM 17938) was associated with a significant decrease in average crying time in infantile colic. There is moderate evidence for this strain and LGG and limited evidence (based on one study each) for the beneficial effect of VSL#3 and a three-strain bifidobacteria mix in abdominal pain FGIDs, particularly in the irritable bowel disease subgroup of children, but not in functional dyspepsia. There is currently no clear evidence of positive effects of oral probiotics in autistic spectrum disorder. Efficacy and safety of other strains or beneficial effects in other conditions still need to be proven, as probiotic properties are strain-specific, and data cannot be extrapolated to other brain-gut or mood diseases or to other probiotics of the same or different species. To transform the use of probiotics from a tempting suggestion to a promising treatment modality in neurogastroenterological disorders more accurate differentiation of the efficacy-proven strains, clarification of dose, duration, and outcome and a careful selection of the target patients are still necessary.

ABSTRACT

INTRODUCTION AND AIMS: The prevalence of functional gastrointestinal disorders (FGIDs) in Argentinean children and adolescents has not yet been studied. Our aim was to determine the prevalence of FGIDs among children and adolescents in Argentina using the Rome III diagnostic criteria. MATERIALS AND METHODS: A total of 483 children, 12-18 years of age, from 3 private schools and 3 public schools, were included in the study. Each child completed the Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III), which is an age-appropriate and previously validated instrument for diagnosing FGIDs according to the Rome III criteria. Sociodemographic data (age, sex, type of school, family structure and size, family history of gastrointestinal disorders) and data on stressful life events were also obtained. RESULTS: The mean age of the population studied was 15 years (standard deviation 1.74, range 12-18, 52.8% boys). Of the respondents, 229 children (47.4%) attended private school and 254 children (52.6%) attended public school. In total, 82 children (17.0%) were diagnosed with an FGID, according to the Rome III criteria. Abdominal migraine (16.4%) was the most common diagnosis, followed by irritable bowel syndrome (7.0%), functional constipation (6.4%), and aerophagia (5.6%). Girls suffered significantly more from FGIDs than boys (22.4 vs. 12.2%, P=.0032). Children attending private school had significantly more FGIDs than children in public schools (20.5 vs. 13.8%, P=.0499). CONCLUSION: FGIDs are common among Argentinean children and adolescents.

ABSTRACT

Functional abdominal pain disorders are highly prevalent in children. These disorders can be present in isolation or combined with organic diseases, such as celiac disease and inflammatory bowel diseases. Intestinal inflammation (infectious and non-infectious) predisposes children to the development of visceral hypersensitivity that can manifest as functional abdominal pain disorders, including irritable bowel syndrome. The new onset of irritable bowel syndrome symptoms in a patient with an underlying organic disease, such as inflammatory bowel disease, is clinically challenging, given that the same symptomatology may represent a flare-up of the inflammatory bowel disease or an overlapping functional abdominal pain disorder. Similarly, irritable bowel syndrome symptoms in a child previously diagnosed with celiac disease may occur due to poorly controlled celiac disease or the overlap with a functional abdominal pain disorder. There is little research on the overlap of functional abdominal disorders with organic diseases in children. Studies suggest that the overlap between functional abdominal pain disorders and inflammatory bowel disease is more common in adults than in children. The causes for these differences in prevalence are unknown. Only a handful of studies have been published on the overlap between celiac disease and functional abdominal pain disorders in children. The present article provides a review of the literature on the overlap between celiac disease, inflammatory bowel disease, and functional abdominal pain disorders in children and establish comparisons with studies conducted on adults.

ABSTRACT

Although neurogastroenterology and motility (NGM) disorders are some of the most frequent disorders encountered by practicing gastroenterologists, a structured competency-based training curriculum developed by NGM experts is lacking. The American Neurogastroenterology and Motility Society (ANMS) and the European Society of Neurogastroenterology and Motility (ESNM) jointly evaluated the components of NGM training in North America and Europe. Eleven training domains were identified within NGM, consisting of functional gastrointestinal disorders, visceral hypersensitivity and pain pathways, motor disorders within anatomic areas (esophagus, stomach, small bowel and colon, anorectum), mucosal disorders (gastro-esophageal reflux disease, other mucosal disorders), consequences of systemic disease, consequences of therapy (surgery, endoscopic intervention, medications, other therapy), and transition of pediatric patients into adult practice. A 3-tiered training curriculum covering these domains is proposed here and endorsed by all NGM societies. Tier 1 NGM knowledge and training is expected of all gastroenterology trainees and practicing gastroenterologists. Tier 2 knowledge and training is appropriate for trainees who anticipate NGM disorder management and NGM function test interpretation being an important part of their careers, which may require competency assessment and credentialing of test interpretation skills. Tier 3 knowledge and training is undertaken by trainees interested in a dedicated NGM career and may be restricted to specific domains within the broad NGM field. The joint ANMS and ESNM task force anticipates that the NGM curriculum will streamline NGM training in North America and Europe and will lead to better identification of centers of excellence where Tier 2 and Tier 3 training can be accomplished.

ABSTRACT

BACKGROUND: Evidence for the efficacy of commonly used drugs in the treatment of childhood functional constipation (FC) is scarce, studies are often of low quality and study designs are heterogeneous. Thus, recommendations for the design of clinical trials in childhood FC are needed. PURPOSE: Members of the Rome Foundation and a member of the Pediatric Committee of the European Medicines Agency formed a committee to create recommendations for the design of clinical trials in children with FC. KEY RECOMMENDATIONS: This committee recommends conducting randomized, double-blind, placebo-controlled, parallel-group clinical trials to assess the efficacy of new drugs for the treatment of childhood FC. Pediatric study participants should be included based on fulfilling the Rome IV criteria for FC. A treatment free run-in period for baseline assessment is recommended. The trial duration should be at least 8 weeks. Treatment success is defined as no longer meeting the Rome IV criteria for FC. Stool consistency should be reported based on the Bristol Stool Scale. Endpoints of drug efficacy need to be tailored to the developmental age of the patient population.

ABSTRACT

BACKGROUND: Over the last few years, the study of the colon and anorectal function has experienced great technical advances that have facilitated the performance of the tests and have allowed a more detailed characterization of reflexes and motor patterns. As a result, we have achieved a much better understanding of the pathophysiology of children with defecation problems. Anorectal and colonic manometry are now commonly used in all major pediatric referral centers as diagnostic tools and to guide the management of children with intractable constipation and fecal incontinence, particularly when a surgical intervention is being considered. PURPOSE: This review highlights some of the recent advances in pediatric colon and anorectal motility testing including indications and preparation for the studies, and how to perform and interpret the tests. This update has been endorsed by the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN).

ABSTRACT

INTRODUCTION AND AIMS: Functional gastrointestinal disorders are among the most common chronic disorders in children worldwide. Studies in schoolchildren from various Latin American countries have shown a high prevalence of functional gastrointestinal disorders, but their prevalence in Mexican schoolchildren is unknown. Our aim was to assess the prevalence of functional gastrointestinal disorders in Mexican schoolchildren in accordance with the Rome III criteria. MATERIAL AND METHODS: Children and adolescents from public and private schools in Monterrey and Cuernavaca privately completed the Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III Version (QPGS-III) in class, using the same methods and questionnaires of previous studies conducted by our group in other Latin American countries. RESULTS: A total of 362 schoolchildren (public school 82, private school 280), with a mean age of 11.6±2.1 years completed the QPGS-III. Ninety-nine schoolchildren (27.3%) met the criteria for a FGID, according to the Rome III criteria. Functional constipation was the most common FGID (12.6%). Irritable bowel syndrome (6.4%) was the most common FGID associated with abdominal pain. There was no significant difference in the prevalence of FGIDs between sexes (P=.8). CONCLUSIONS: We found a high prevalence of FGIDs in Mexican school-aged children and adolescents.

ABSTRACT

BACKGROUND: There is little published evidence of efficacy for the most commonly used treatments. Thus, there is an urgent need to conduct clinical trials on existing and novel therapies. PURPOSE: In order to address these issues the Rome Foundation and members of the Pediatric Committee of the European Medicines Agency formed a subcommittee on clinical trials to develop guidelines for the design of clinical trials in children with irritable bowel syndrome (IBS). The following recommendations are based on evidence from published data when available and expert opinion. KEY RECOMMENDATIONS: The subcommittee recommends randomized, double-blind, placebo-controlled, parallel-group, clinical trials to assess the efficacy of new drugs. The combined endpoints for abdominal pain are a decrease in intensity of at least 30% compared with baseline and to meet or exceed the Reliable Change Index (RCI) for the sample. Stool consistency is measured with the Bristol Stool Scale Form (BSFS). The subcommittee recommends as entry criteria for abdominal pain a weekly average of worst abdominal pain in past 24 h of at least 3.0 on a 0-10 point scale or at least 30 mm in 100 mm Visual Analog Scale. For stool endpoints the committee recommends an average stool consistency lower than 3 in the BSFS during the run-in period for clinical trials on IBS-C and an average stool consistency greater than 5 in the BSFS during the run-in period for clinical trials on IBS-D. Changes in stool consistency are the primary endpoints for both IBS with diarrhea (IBS-D) and IBS with constipation (IBS-C).

ABSTRACT

BACKGROUND: We studied the epidemiology of functional gastrointestinal disorders (FGIDs) in school-aged Salvadoran children using standardized diagnostic criteria. AIMS: To determine the prevalence of FGIDs in school-aged children in El Salvador. MATERIAL AND METHODS: A total of 395 children participated in the study (one public school and one private school). School children completed the Spanish version of the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III (QPGS-III), an age-appropriate and previously validated instrument for diagnosing FGIDs according to the Rome III criteria. Sociodemographic (age, sex, type of school) and familial (family structure and size, family history of gastrointestinal disorders) data were obtained. RESULTS: The mean age of the sample was 11.8 years ± 1.6 SD (median 10, range 8-15) and 59% of the participants were female. Eighty-one children met the diagnostic criteria for a FGID (20%). Defecation disorders were the most common group of FGIDs. Functional constipation was diagnosed in 10% of the children and 9.25% were diagnosed with abdominal pain-related FGIDs (most commonly IBS, 3.75%). IBS overlapped with functional dyspepsia in 11% of the cases. Children with FGIDs frequently reported nausea. Children attending private school and older children had significantly more FGIDs than children in public school and younger children. CONCLUSIONS: FGIDs are common in school-aged Salvadoran children.

ABSTRACT

BACKGROUND: The Food and Drug Administration (FDA) recommended ≥30% decrease on patient-reported outcomes for pain be considered clinically significant in clinical trials for adults with irritable bowel syndrome. This percent change approach may not be appropriate for children. We compared three alternate approaches to determining clinically significant reductions in pain among children. METHODS: 80 children with functional abdominal pain participated in a study of the efficacy of amitriptyline. Endpoints included patient-reported estimates of feeling better, and pain Visual Analog Scale (VAS). The minimum clinically important difference in pain report was calculated as (i) mean change in VAS score for children reporting being 'better'; (ii) percent changes in pain (≥30% and ≥50%) on the VAS; and (iii) statistically reliable changes on the VAS for 68% and 95% confidence intervals. KEY RESULTS: There was poor agreement between the three approaches. 43.6% of the children who met the FDA ≥30% criterion for clinically significant change did not achieve a reliable level of improvement (95% confidence interval). CONCLUSIONS & INFERENCES: Children's self-reported ratings of being better may not be statistically reliable. A combined approach in which children must report improvement as better and achieve a statistically significant change may be more appropriate for outcomes in clinical trials.

ABSTRACT

BACKGROUND: The Bristol Stool Form Scale (BSFS) and a modified child-friendly version (M-BSFS) are frequently used in clinical practice and research. These scales have not been validated in children. 3-D stool scale models may be better adapted to the child's development. AIMS: To assess the usefulness of the BSFS, M-BSFS, and a newly developed 3-D stool scale in children. METHODS: Fifty children were asked to rank the picture cards of the BSFS and 3-D models from hardest to softest and to match the pictures with descriptors for each stool type. RESULTS: Thirty percent of the children appropriately characterized the stools as hard, loose, or normal using the BSFS vs. 36.6% with the 3-D model (p=0.27). Appropriate correlation of stools as hard, loose, or normal consistency using the BSFS vs. the 3-D model by age group was: 6 to 11-year-olds, 27.5% vs. 33.3% (p=0.58) and 12 to 17-year-olds, 32.1% vs. 39.5% (p=0.41). Thirty-three percent correlated the BSFS pictures with the correct BSFS words, 46% appropriately correlated with the M-BSFS words, and 46% correlated the 3-D stool models with the correct wording. CONCLUSIONS: The BSFS and M-BSFS that are widely used as stool assessment instruments are not user-friendly for children. The 3-D model was not found to be better than the BSFS and the M-BSFS.

ABSTRACT

BACKGROUND: Functional gastrointestinal disorders (FGIDs) are common digestive conditions characterized by chronic or recurrent symptoms in the absence of a clearly recognized gastrointestinal etiology. The biopsychosocial model, the most accepted concept explaining chronic pain conditions, proposes that the interplay of multiple factors such as genetic susceptibility, early life experiences, sociocultural issues, and coping mechanisms affect children at different stages of their lives leading to the development of different pain phenotypes and pain behaviors. Early life events including gastrointestinal inflammation, trauma, and stress may result in maladaptive responses that could lead to the development of chronic pain conditions such as FGIDs. AIMS: In this review, we discuss novel findings from studies regarding the long-term effect of early life events and their relationship with childhood chronic abdominal pain and FGIDs. METHODS: A bibliographic search of the PubMed database was conducted for articles published over the last 20 years using the keywords: "Functional gastrointestinal disorders", "chronic abdominal pain", "chronic pain", "gastrointestinal inflammation", and "early life events". Forty-three articles were chosen for review. RESULTS: Based on the current evidence, events that take place early in life predispose children to the development of chronic abdominal pain and FGIDs. Conditions that have been studied include cow's milk protein hypersensitivity, pyloric stenosis, gastrointestinal infections, and Henoch-Schonlein purpura, among others. CONCLUSIONS: Early events may play an important role in the complex pathogenesis of functional gastrointestinal conditions. Timely intervention may have a critical impact on the prevention of this group of chronic incapacitating conditions.

ABSTRACT

OBJECTIVE: The possible effect of obesity in the outcome of treated children with abdominal pain-related functional gastrointestinal disorders (FGIDs) has not yet been studied. We hypothesized that obesity is associated with a poor long-term prognosis in children with FGIDs. STUDY DESIGN: Prospective cohort study in an outpatient clinic-based sample of patients diagnosed with abdominal pain-related FGIDs. Principal outcome measured was persistence of pain at long-term follow-up (12-15 months). Frequency of pain, intensity of pain, school absenteeism and disruption of daily activities were compared between obese and non-obese subjects. RESULTS: The group mean age was 13.27±3.84 years, distribution of diagnosis was 32% (functional abdominal pain), 42.5% (irritable bowel syndrome) and 25.5% (functional dyspepsia). Overall, 20.2% of patients were obese. A total of 116 patients (61.7%) reported abdominal pain and 72 (38.3%) were asymptomatic at long-term follow-up. Obese patients were more likely to have abdominal pain (P<0.0001), higher intensity of pain (P=0.0002), higher frequency of pain (P=0.0032), school absenteeism (P<0.0001) and disruption of daily activities (P<0.0001) at follow-up than non-obese patients. CONCLUSION: Obesity is associated with poor outcome and disability at long-term follow-up in children with abdominal pain-related FGIDs. Our novel findings could have important implications in the prognosis and management of FGIDs.

ABSTRACT

BACKGROUND AND AIMS: : Abdominal pain-related functional gastrointestinal disorders (AP-FGIDs) following bacterial acute gastroenteritis (AGE) have been demonstrated in adults and children. An adult study demonstrated AP-FGIDs resulting from an outbreak of viral AGE. Viral AGEs are common in children. Thus, the demonstration of AP-FGIDs occurring after a viral infection in children could constitute a significant finding. The aim of the study was to investigate the development of FGIDs following an episode of acute rotavirus gastroenteritis in children. This is the first pediatric multicenter study designed to assess postviral AP-FGIDs. PATIENTS AND METHODS: : It is a cohort study. Inclusion criteria of the study are children ages 4 to 18 years with history of AGE secondary to rotavirus. Sample size is 44 exposed and 44 controls (unidirectional alpha of 0.05, power of 0.80). Children consulting at 2 hospitals (Chicago, IL, and Naples, Italy) for AGE (2002-2004) who tested positive for rotavirus were randomly contacted by telephone >2 years after the episode. Each exposed child who visited the emergency department or outpatient site for acute trauma or well-child visit within 4 weeks of the index case was matched with a control of the same age and sex. Gastrointestinal symptoms and disability were evaluated with a validated pediatric questionnaire. RESULTS: : Eighty-eight patients (46 boys, mean age 5.3 years) were recruited. Contacted patients presented with AGE in 2002 (9), 2003 (11), and 2004 (24). Seven (16%) exposed patients and 3 (7%) controls reported AP-FGIDs (P = 0.31). CONCLUSIONS: : Our study suggests that rotavirus infection does not seem to place children at increased risk for AP-FGIDs at long-term follow-up. Larger, prospective studies should be conducted to evaluate whether rotavirus gastroenteritis leads to AP-FGIDs in children.

ABSTRACT

BACKGROUND: Anxiety and depression, conditions frequently associated with childhood chronic abdominal pain (AP), are characterized by seasonal exacerbations. A seasonal pattern characterized by a higher frequency of consultations for AP during winter has been suspected but has never, to our knowledge, been demonstrated. We hypothesize the presence of a seasonal variation in AP consultations with a winter predominance. AIMS: To determine the seasonal distribution of AP consultations among centers across time and geographic latitude. PATIENTS AND METHODS: This was a retrospective cohort study. The number of outpatient consultations from primary care clinics and every pediatric specialty clinic that resulted in a diagnosis of AP and the total number of outpatient consultations (2001-2004) from 6 tertiary care institutions (Chicago, Pittsburgh, Wilmington, Pensacola, Orlando, Jacksonville) was determined. Rates of consultations were compared across time and between cities. Four time periods of interest, with 2- and 3-month definitions, were arbitrarily selected. Seasonal rates across time were compared separately for each of the 2-month (January-February vs June-July) and 3-month periods (January-March vs June-August). Logistic regression models for each city were used to determine variations in the rate of outpatient AP cases by season or by year. RESULTS: A total of 3,929,522 outpatient consultations and 73,591 AP consultations were analyzed. The rates of AP consultations were consistently higher in the winter months at all of the sites. The results differed between sites at northern and southern latitudes. CONCLUSIONS: There seems to be a seasonal variation in consultation patterns for AP at the tertiary care level. A possible role of daylight hours, climate, latitude, and stress is proposed.
