Wollmer E, Ungell AL, Nicolas JM, Klein S. Review of paediatric gastrointestinal physiology relevant to the absorption of orally administered medicines. Adv Drug Deliv Rev 2022; 181:114084. [PMID: 34929252 DOI: 10.1016/j.addr.2021.114084] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 11/13/2021] [Accepted: 12/13/2021] [Indexed: 12/11/2022]
Abstract
Despite much progress in regulations to improve paediatric drug development, there remains a significant need to develop better medications for children. For the design of oral dosage forms, a detailed understanding of the specific gastrointestinal (GI) conditions in children of different age categories and how they differ from GI conditions in adults is essential. Several review articles have been published addressing the ontogeny of GI characteristics, including luminal conditions in the GI tract of children. However, the data reported in most of these reviews are of limited quality because (1) information was cited from very old publications and sometimes low quality sources, (2) data gaps in the original data were filled with textbook knowledge, (3) data obtained on healthy and sick children were mixed, (4) average data obtained on groups of patients were mixed with data obtained on individual patients, and (5) results obtained using investigative techniques that may have altered the outcome of the respective studies were considered. Consequently, many of these reviews draw conclusions that may be incorrect. The aim of the present review was to provide a comprehensive and updated overview of the available original data on the ontogeny of GI luminal conditions relevant to oral drug absorption in the paediatric population. To this end, the PubMed and Web of Science metadatabases were searched for appropriate studies that examined age-related conditions in the oral cavity, esophagus, stomach, small intestine, and colon. Maturation was observed for several GI parameters, and corresponding data sets were identified for each paediatric age group. However, it also became clear that the ontogeny of several GI traits in the paediatric population is not yet known. The review article provides a robust and valuable data set for the development of paediatric in vitro and in silico biopharmaceutical tools to support the development of age-appropriate dosage forms. In addition, it provides important information on existing data gaps and should provide impetus for further systematic and well-designed in vivo studies on GI physiology in children of specific age groups in order to close existing knowledge gaps and to sustainably improve oral drug therapy in children.

Abstract
Since its clearance for use throughout the world, capsule endoscopy (CE) has become an important diagnostic tool, helping us to understand and document both normal and abnormal findings in the small intestine, especially in children, since CE usually can be employed without sedation or radiation. The indications in children and adults are similar, though their relative frequencies are different, with evaluation of potential and known inflammatory bowel disease the most common in the pediatric population, with CE also yielding increased diagnostic certainty compared to radiographic studies and surrogate biomarkers. Newer capsules now create opportunities to expand that understanding and our practices so that we can learn when and how to employ CE and pan-enteric CE to better monitor and guide therapy. It will take further studies to determine the best uses for CE and how to select the appropriate candidates, especially with ongoing concern about capsule ingestion vs. placement, the potential for capsule retention (particularly in known Crohn's disease), still elusive optimal methods for bowel cleansing, and the most meaningful scoring for research and clinical use.

Abstract
BACKGROUND AND AIM The implementation rates of pediatric gastrointestinal endoscopy are increasing with advancements in the devices used and pediatricians' skills. As part of the Japan Pediatric Endoscopy Study Group, we aimed to investigate the rates of pediatric gastrointestinal endoscopy use and the associated adverse events through a nationwide survey. METHODS A questionnaire was sent to 630 institutions in Japan. The numbers of pediatric gastrointestinal endoscopy cases and adverse events occurring during endoscopy, from April 2011 to March 2016, were investigated. RESULTS Responses were obtained from 445 facilities. The total number of pediatric gastrointestinal endoscopies was 37 447 and that of endoscopic examinations was 32 219 (86.0%), with esophagogastroduodenoscopy accounting for 18 484 cases; ileal colonoscopy, 11 936; endoscopic retrograde cholangiopancreatography, 389; wireless capsule endoscopy, 897; and balloon-assisted enteroscopy, 513. The number of endoscopic treatments was 5228, followed by balloon dilatation (1703), foreign body removal (989), and polypectomy (822); 201 adverse events (0.54%) occurred, 79 of which presented during endoscopic examination (0.25%). Eight serious perforations were noted in 0.0054% and 0.025% of those undergoing esophagogastroduodenoscopy and colonoscopy, respectively. Overall, 122 adverse events (2.33%) occurred in association with endoscopic treatment. One case of cardiopulmonary arrest occurred because of accidental extubation. However, no deaths occurred. CONCLUSION Endoscopic examinations had a slightly higher adverse event rate, because of an increase in endoscopic retrograde cholangiopancreatography and small intestine enteroscopy, than that reported in previous studies, but the adverse event rate of endoscopic treatment did not increase.

Abstract
A treat-to-target strategy, in which treatment is continuously adjusted according to the results of scheduled objective monitoring, is optimal for patients with Crohn's disease (CD) in the era of biologics. The small bowel is a common site of intractable CD, which may result from multiple strictures or expanding lesions. To improve the prognosis of patients with small bowel CD, lesions should be proactively monitored within the subclinical phase. Objective assessment of small bowel lesions is technically difficult, however, due to the relatively poor correlation between endoscopic activity and clinical symptoms or biomarker titers. The presence of proximal small bowel lesions and asymptomatic "Real Silent CD" must be considered. Endoscopy remains the gold standard to assess these lesions. In clinical practice, the advantages and disadvantages of each imaging modality and biomarker must be carefully weighed for appropriate application and reliable monitoring. The prevalence of small bowel lesions depends on the precision of the imaging modality used for detection. Clinical management should be based on the dominant location of the intestinal lesions rather than classical classification. Optimal strategies for detecting and treating small bowel lesions in patients with CD must be developed utilizing reliable, precise, and objective monitoring.

Abstract
BACKGROUND A patency capsule (PC) can help predict capsule endoscope (CE) retention; however, PC tolerability is unknown in children. We retrospectively evaluated PC tolerability in school-aged children. METHODS Sixty-one patients (median age, 12.9 years; range 7.4-17.3 years) who underwent PC examination were analyzed for occurrence and determinants of ingestion difficulty and relationships between ingestion of the 2 capsules. We defined ingestion difficulty as taking 30 min or more, or failure, to ingest the PC. RESULTS Thirty-nine patients (64%) successfully ingested the PC without ingestion difficulty. The other 22 had ingestion difficulty and were significantly younger (11.7 ± 2.2 vs. 13.0 ± 1.8 years; p = 0.04) and shorter (143.3 ± 14.0 vs. 154.6 ± 12.5 cm; p = 0.003) than those without ingestion difficulty. Multivariate analysis showed that the most significant factor for predicting PC ingestion difficulty was height (cutoff value, 152 cm). Time to ingest the CE was significantly shorter than that for PC ingestion (8 ± 32 vs. 20 ± 58 min; p = 0.01). All patients indicated that ingestion of the CE was easier because of its smooth surface compared with the PC. CONCLUSIONS PC ingestion is not guaranteed in school-aged children. PC ingestion ability should be evaluated by considering the child's height and lack of experience ingesting capsules prior to PC examination.

Abstract
Management of small bowel diseases has evolved since the advent of capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE). One of the most common indications for enteroscopy is obscure gastrointestinal bleeding (OGIB), followed by small bowel stenosis, tumors, and inflammatory bowel disease. Although enteroscopes have been regarded as useful tools, correct guidelines are required to ensure that we manipulate these enteroscopes safely and efficiently in clinical practice. Herein, the Japanese Gastroenterological Endoscopy Society has developed 'Clinical Practice Guidelines for Enteroscopy' in collaboration with the Japanese Society of Gastroenterology, the Japanese Gastroenterological Association, and the Japanese Association for Capsule Endoscopy. These guidelines are based on the evidence available until now, but small bowel endoscopy is a relatively new technology, so the guidelines include recommendations based on a consensus reached among experts when the evidence has not been considered sufficient. These guidelines were not designed to be disease-based, but focus on how we should use small bowel CE and BAE in everyday clinical practice.

Abstract
INTRODUCTION Capsule Endoscopy (CE) in children has limitations based mainly on age. The objective of this consensus was reviewing the scientific evidence. MATERIAL AND METHODS Some experts from the Spanish Society of Gastroenterology (SEPD) and Spanish Society for Pediatric Gastroenterology, Hepatology, and Nutrition (SEGHNP) were invited to answer different issues about CE in children. These sections were: a) Indications, contraindications and limitations; b) efficacy of CE in different clinical scenarios; c) CE performance; d) CE-related complications; e) Patency Capsule; and f) colon capsule endoscopy. They reviewed relevant questions on each topic. RESULTS The main indication is Crohn's disease (CD). There is no contraindication for the age and in the event that the patient not to swallow it, it should be administered under deep sedation with endoscopy and specific device. The CE is useful in CD, for the management of OGIB in children and in Peutz-Jeghers syndrome (in this indication has the most effectiveness). The main complication is retention, which should be specially taken into account in cases of CD already diagnosed with malnutrition. A preparation regimen based on a low volume of polyethylene glycol (PEG) the day before plus simethicone on the same day is the best one in terms of cleanliness although does not improve the results of the CE procedure. CONCLUSIONS CE is safe and useful in children. Indications are similar to those of adults, the main one is CD to establish both a diagnosis and disease extension. Moreover, only few limitations are detected in children.

Abstract
AIM To evaluate the prevalence of nodular lymphoid hyperplasia (NLH) in adult patients undergoing colonoscopy and its association with known diseases.
METHODS We selected all cases showing NLH at colonoscopy in a three-year timeframe, and stratified them into symptomatic patients with irritable bowel syndrome (IBS)-type symptoms or suspected inflammatory bowel disease (IBD), and asymptomatic individuals undergoing endoscopy for colorectal cancer screening. Data collection included medical history and final diagnosis. As controls, we considered all colonoscopies performed for the aforementioned indications during the same period.
RESULTS One thousand and one hundred fifty colonoscopies were selected. NLH was rare in asymptomatic individuals (only 3%), while it was significantly more prevalent in symptomatic cases (32%). Among organic conditions associated with NLH, the most frequent was IBD, followed by infections and diverticular disease. Interestingly, 31% of IBS patients presented diffuse colonic NLH. NLH cases shared some distinctive clinical features among IBS patients: they were younger, more often female, and had a higher frequency of abdominal pain, bloating, diarrhoea, unspecific inflammation, self-reported lactose intolerance and metal contact dermatitis.
CONCLUSION About 1/3 of patients with IBS-type symptoms or suspected IBD presented diffuse colonic NLH, which could be a marker of low-grade inflammation in a conspicuous subset of IBS patients.

Abstract
Background and Aim. The third-generation capsule endoscopy (SB3) was shown to have better image resolution than that of SB2. The aim of this study was to compare SB2 and SB3 regarding detectability of esophageal varices (EVs). Methods. Seventy-six consecutive liver cirrhosis patients (42 men; mean age: 67 years) received SB3, and 99 (58 men; mean age, 67 years old) received SB2. All patients underwent esophagogastroduodenoscopy within 1 month prior to capsule endoscopy as gold standard for diagnosis. The diagnosis using SB3 and SB2 for EVs was evaluated regarding form (F0–F3), location (Ls, Lm, and Li), and the red color (RC) sign of EVs. Results. SB2 and SB3 did not significantly differ on overall diagnostic rates for EV. Sensitivity, specificity, positive predictive value, and negative predictive value of SB2/SB3 for EV diagnosis were, respectively, 65%/81%, 100%/100%, 100%/100%, and 70%/62%. However, the diagnostic rates for EV form F1 were 81% using SB3 and 52% using SB2 (P = 0.009). Further, the diagnostic rates for Ls/Lm varices were 79% using SB3 and 81% using SB2, and, for Li, varices were 84% using SB3 and 52% using SB2 (P = 0.02). Conclusion. SB3 significantly improved the detectability of EVs compared with SB2.

Abstract
Video capsule endoscopy (CE) for evaluation the esophagus (ECE), small bowel (SBCE) and the colon (CCE) is particularly useful in pediatrics, because this imaging modality does not require ionizing radiation, deep sedation or general anesthesia. The risk of capsule retention appears to be dependent on indication rather than age and parallels the adult experience by indication, making SBCE a relatively safe procedure with a significant diagnostic yield. The newest indication, assessment of mucosal change, greatly enhances and expands its potential benefit. The diagnostic role of CE extends beyond the SB. The use of ECE also may enhance our knowledge of esophageal disease and assist patient care. Colon CCE is a novel minimally invasive and painless endoscopic technique allowing exploration of the colon without need for sedation, rectal intubation and gas insufflation. The limited data on ECE and CCE in pediatrics does not yet allow the same conclusions regarding efficacy; however, both appear to provide safe methods to assess and monitor mucosal change in their respective areas with little discomfort. Moreover, although experience has been limited, the patency capsule may help lessen the potential of capsule retention; and newly researched protocols for bowel cleaning may further enhance CE’s diagnostic yield. However, further research is needed to optimize the use of the various CE procedures in pediatric populations.

Abstract
AIM: To assess the safety and utility of capsule endoscopy (CE) for children who are unable to swallow the capsule endoscope.
METHODS: The medical records of all of the children who underwent CE between 2010 and 2012 were retrospectively reviewed. The patients were divided into 2 groups: group A included patients who were unable to swallow the capsule endoscope, and group B included patients who were able to swallow it. For the patients who were unable to swallow the capsule endoscope, it was placed in the duodenum endoscopically. The small bowel transit time, endoscopic diagnosis and complications of the 2 groups were compared.
RESULTS: During the study period, 28 CE procedures were performed in 26 patients. Group A included 11 patients with a median age of 2 years (range 10 mo-9 years), and group B included 15 patients with a median age of 12 years (range 8 years-16 years). The lightest child in the study weighed 7.9 kg. The detection rates did not differ between the 2 groups. The median small bowel transit time was 401 min (range 264-734 min) in group A and 227 min (range 56-512 min) in group B (P = 0.0078). No serious complications, including capsule retention, occurred. No significant mucosal trauma occurred in the pharynx, esophagus, stomach or duodenum when the capsule was introduced using an endoscope.
CONCLUSION: CE is a safe and useful procedure for infants and young children who are unable to swallow the capsule endoscope.

Abstract
Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is an extremely rare illness characterised by chronic or relapsing subileus status resulting from multiple small intestinal fibrous strictures and multiple shallow ulcers of the small bowel. The etiology is unknown and pathogenesis is not fully understood. Therapy with systemic glucocorticosteroids is the treatment of choice. However, most patients develop corticosteroid dependence. Deep enteroscopy enables precise diagnostic work, possible endoscopic treatment of stenoses; may obviate the need for surgery and prevent excessive small bowel resections.

Abstract
BACKGROUND AND OBJECTIVE Because capsule endoscopy (CE) avoids ionizing radiation, deep sedation, and general anesthesia, CE may be valuable in pediatrics. We report a single pediatric center's experience with the use and safety of CE. METHODS In a retrospective review of consecutive CE studies, 284 CE studies were performed in 277 patients with a mean age of 15 (±3.7) years during a 5-year period. The youngest to swallow the capsule was 4.6 years old. Twenty capsules were placed. Overall, 245 (86%) patients underwent CE for suspected (184, 65%) or confirmed (61, 21%) Crohn disease (CD); 27 (9.5%) anemia or gastrointestinal bleeding; 6 (2%) polyposis; and 4 (1.4%) celiac disease. RESULTS Positive findings were observed in 205 (72%) of the studies, with 152 (54%) having small bowel findings. Of these, 72 (47%) were diagnostic. Gastric (95, 33%) and colonic (31, 11%) abnormalities were also identified. Five CE studies (1.8%) resulted in retention of the capsule in nonsurgical patients. A patency capsule before CE in 23 patients allowed 19 CE to proceed with only 1 retained capsule. In 65 (21%) patients, the video capsule did not enter the colon before the video's end. Of these, 36 (65%) had significant findings, including 27 (49%) documenting small bowel (SB) CD. CONCLUSIONS CE is useful to diagnose SB disease in children. Even in a study population with a high prevalence of confirmed and suspected CD, the risk of retention remains small. The patency capsule may lessen that risk. CE may identify gastric or colonic disease even when SB lesions are not present.

Abstract
BACKGROUND AND AIMS Chronic nonspecific multiple ulcer of the small intestine is a recently proposed enteropathy characterized by persistent blood and protein loss from the small-bowel. We examined possible segregation of the disease in family pedigrees. METHODS All cases of the disease diagnosed at our institution were reviewed with respect to particular focuses on the presence of close consanguinity in the families, the enteroscopic findings and the long-term clinical course. The diagnosis was based on persistent occult gastrointestinal bleeding and hypoproteinemia for more than 5 years, and irregularly shaped shallow ulcers in the ileum. RESULTS During a 45-year-period, 13 patients were diagnosed as having the disease. There were 11 females and 2 males, with ages ranging from 8 to 37 years at the time of the initial presentation and with those from 13 to 38 years at the diagnosis. Enteroscopy performed in 11 patients with a time duration ranging from 0.5 to 44 years after the diagnosis revealed active ileal ulcers in 10 patients. Parents' consanguineous marriage was verified in 6 patients, two of whom also had siblings with the enteropathy. Another patient without consanguinity had a sibling with protein-losing enteropathy. CONCLUSION Chronic nonspecific multiple ulcer of the small intestine seems to segregate in offspring from consanguineous marriage.

Abstract
BACKGROUND & AIMS To further our understanding of capsule endoscopy (CE) in children, we systematically compiled data on indications and outcomes and evaluated the effectiveness of CE on patient management using meta-analyses. METHODS We searched the Medline and PubMed databases (January 2001-May 2010) for English language citations of use of CE in patients ≤18 years old. Duplicate reports and those that included 5 patients or fewer were removed. We analyzed data from 15 source documents with 740 CE procedures in 723 patients. RESULTS Suspicion or evaluation of inflammatory bowel diseases was the most common indication for CE (54%: 34% for patients suspected to have Crohn's disease [CD], 16% for patients known to have CD, 1% for patients with ulcerative colitis, and 3% for patients with indeterminate colitis). Completion and retention rates were 86.2% (95% confidence interval [CI], 81.5-90.3) and 2.6% (95% CI, 1.5-4.0), respectively. Retention rates for children that underwent gastric (0.5%) or small bowel (1.9%) CE were similar to those of adults, by indication. For CE, 65.4% of procedures resulted in positive findings (95% CI, 54.8-75.2). Where reported, 69.4% of CE examinations (95% CI, 46.9-87.9) resulted in a new diagnosis and 68.3% (95% CI, 43.6-88.5) led to change in therapy. CONCLUSIONS The relative frequency of CE indications varies among pediatric and adult patients. In pediatric patients, CE is used primarily to evaluate patients with CD - to aid in diagnosis, monitor disease severity, and assist patient management. Retention rates appear to be related to indication, rather than patient age; capsule retention is relatively infrequent for adults and children.
