Abstract
Pyloric stenosis commonly affects infants and rarely causes gastric outlet obstruction in adolescents and older children. We present the case of an 11-year-old girl with a 2-month history of recurrent postprandial vomiting and weight loss. On physical examination, the patient presented with abdominal distension. Upper gastrointestinal endoscopy revealed a very small pyloric orifice through which the endoscope could not be advanced. Abdominal ultrasonography and a computed tomography confirmed pylorus thickening. She underwent Heineke-Mikulicz pyloroplasty with symptom resolution.

Abstract
Introduction Wilson's disease (WD) is a rare and underdiagnosed genetic disorder caused by anomalous tissue copper deposition, and for which epidemiological studies, specifically in Portugal, are scarce. Objectives This study aimed to evaluate the prevalence and incidence of WD and provide a description of its main clinical and laboratory features. Methods A retrospective study was carried out, with a search between 1995 and 2015, of all patients with a minimum follow-up of three months and birth confirmed in the northern region of Portugal, with an estimated population of 3,689,682 inhabitants. Database collection was based on the Portuguese National Health Service's clinical coding system, relying on clinical data from 13 northern Portuguese hospitals, liver biopsy histology results, and hospital prescription records. Clinical and biochemical correlations were statistically assessed using chi-square, Mann-Whitney U, Friedman, and Wilcoxon tests. Results Over the 20-year period, a prevalence of 1:37.000 and an incidence of one per million person-year was found. A total of 94 patients were analyzed, with a slight male predominance (53%), the majority with the onset of clinical manifestations in pediatric age (56%), with a median age at diagnosis of 16.6 years (interquartile range of 12.3-20,.8 years). Most patients presented with predominant liver disease (54.8%), with more than a third with cirrhosis; mixed hepatic and neurological manifestations in 17.9%; and mainly neurological symptoms in 10.7% of the patients. Neurological impairment was strongly associated with delayed development of the manifestations of the disease (p = 0.001) and also a higher detection of Kayser-Fleischer rings (p < 0.001), present in 27.0% of the patients. Regarding therapy, penicillamine has been the most widely used, with adverse reactions reported in 24.8%. At six and 12 months after initiation of therapy, a significant decrease in liver enzymes was found (ALT: p = 0.002; AST: p = 0.002, respectively), but no significant reduction was observed in urinary copper excretion. Conclusion This was one of the first studies regarding WD prevalence in a Portuguese population, contributing to a better understanding of the epidemiology, diagnosis, and management of WD in the northern region of Portugal. WD should be considered in any individual with unexplained hepatic or neurological manifestations, and initial symptoms may manifest at an early age, even in children less than five years old. A high percentage of patients were identified in the early stages of the disease by asymptomatic elevation of transaminases. Following copper chelation therapy, cytolysis markers appear to be more sensitive indicators of treatment response.

EVOLUTION OF DIAGNOSTIC DELAY IN PEDIATRIC INFLAMMATORY BOWEL DISEASE AND THE IMPACT OF THE COVID-19 PANDEMIC. ARQUIVOS DE GASTROENTEROLOGIA 2023; 60:91-97. [PMID: 37194785 DOI: 10.1590/s0004-2803.202301000-12] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Accepted: 01/30/2023] [Indexed: 05/18/2023]
Abstract
BACKGROUND Pediatric inflammatory bowel disease (IBD) is increasingly prevalent, but diagnosis can still be challenging. Diagnostic delay is particularly deleterious in this age group. OBJECTIVE This study explores the evolution of diagnostic delay in pediatric IBD and the influence of the COVID-19 pandemic. METHODS Retrospective study including all pediatric IBD patients diagnosed during 2014, 2019 and 2020 in a tertiary hospital. Diagnostic delay, time to first medical visit, time to pediatric gastroenterologist (PG) visit and time to diagnosis were calculated and compared within a gap of five years (2019 and 2014) and with the year of onset of the pandemic (2020 and 2019). RESULTS A total of 93 participants were included (2014: 32, 2019: 30, 2020: 31). No significant differences were observed in diagnostic delay, time to first medical visit in Crohn's disease (CD), time to PG visit and time to diagnosis when comparing 2019-2014 and 2020-2019. Time to first visit in ulcerative colitis (UC) and Undetermined-IBD increased in 2019 (P=0.03), with new decrease in 2020 (P=0.04). Diagnostic delay was longer in DC compared to UC plus Undetermined-IBD. CONCLUSION Diagnostic delay is still an important matter in pediatric IBD, with no significant change over the last years. The time to the first PG visit and the time for diagnosis seem to have the greatest impact on diagnostic delay. Thus, strategies to enhance recognition of IBD symptoms among first-line physicians and to improve communication, facilitating referral, are of utmost importance. Despite the restraints in the health care system caused by the pandemic, time to diagnosis in pediatric IBD was not impaired during 2020 in our center.

Abstract
Terminal ileitis is a common condition defined as inflammation of the terminal portion of the ileum, which is typically associated with inflammatory bowel disease (IBD), classically Crohn's disease (CD). However, it can have other etiologies, including drug-induced ones. Isotretinoin is an effective and commonly used treatment for acne vulgaris, presenting multiple adverse effects. There have been discussions over its association with enteric inflammation, particularly over IBD emergence risk. We report a case of a previously healthy 17-year-old female who presented transitory clinical, laboratory, imaging, and endoscopic evidence of distal ileitis, temporally related to extended isotretinoin treatment and mimicking CD. Repeated clinical, laboratory, imaging, and endoscopic reassessment after isotretinoin discontinuation confirmed an almost complete resolution of the condition, avoiding IBD misdiagnosis and specific medication initiation. Our case highlights the differential diagnosis of ileitis as being of critical importance to avoid further unnecessary diagnostic investigations and inadequate treatment. Serial re-evaluation may be of key importance to reach a final diagnosis. Although recent literature suggests that isotretinoin is not associated with an increased IBD risk, our case highlights the possibility of it inducing small bowel injury and inflammation, similar to what has been reported with other drugs.

Incidence Trends of Inflammatory Bowel Disease in a Southern European Country: A Mirror of the Western World? Clin Transl Gastroenterol 2022; 13:e00481. [PMID: 35347090 PMCID: PMC9132531 DOI: 10.14309/ctg.0000000000000481] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 02/09/2022] [Indexed: 12/07/2022] Open
Abstract
INTRODUCTION Inflammatory bowel disease (IBD) affects people from all age categories worldwide. Although the incidence of the disease is stabilizing or decreasing in most Western world countries, its prevalence is still increasing because of the rise in life expectancy and better disease management. This work intends to identify the trends related to IBD incidence nationwide, analyzing regional, sex, and age distributions. METHODS Data were provided by the Portuguese Shared Services of the Ministry of Health. This study consisted of a retrospective analysis of all first consultations coded for "Chronic enteritis/ulcerative colitis" (D94) in a primary healthcare setting, between 2017 and 2020, in Portugal. The primary outcome measure was the IBD incidence rate per 100,000 inhabitants. We also calculated the incidence rate per person-year and forecasted incidence until 2024. RESULTS Between 2017 and 2019, the incidence rate of IBD in Portugal decreased from 54.9 to 48.6 per 100,000 inhabitants. The average incidence was 20 new cases of IBD per 1,000 person-year. It was predicted that, in December 2023, IBD incidence would reach 305.4 new cases (95% Prediction Interval 156.6-454.3), a similar result to the values forecasted for December 2021 (305.4, 95% Prediction Interval 197.3-413.6). DISCUSSION The incidence of IBD slightly declined from 2017 to 2019, and it is posed to stabilize in the future. The presented data are of the utmost importance for the characterization of IBD in Southern European countries and the establishment of future health policies in the setting of compounding prevalence in the Western world.

Abstract
Introduction Acute COVID-19 in pediatric and young adult patients tends to be milder in severity compared to adult infection. Recent studies seem to show that inflammatory bowel disease (IBD) patients are at no greater risk than the general population. We aim to describe our experience in the follow-up of pediatric and young adult patients with IBD followed in our center and determine possible risk factors of said population for severe COVID-19. Methods We performed a retrospective study of all patients aged under 25 years followed for IBD at the Unit of Pediatric Gastroenterology in a tertiary center between December 2019 and April 2021 evaluating the incidence of COVID-19 and characterization of positive cases. Results Of the 268 participants, 24 had COVID-19: the mean age was 19 years old and gender had an equal distribution; 75% (n = 18) had Crohn's disease, whereas only 25% (n = 6) had ulcerative colitis. Most patients were in clinical remission (n = 21). The majority of patients were under treatment with a tumor necrosis factor (TNF) antagonist (58%, n = 14), mainly infliximab, and most had no comorbidities other than IBD (83%). Regarding COVID-19, 17% of the patients were asymptomatic while the rest had only mild symptoms. There were no reported gastrointestinal complaints, no complications nor hospitalizations. Most patients did not require interruption of their IBD treatment. Conclusions Our data suggest that pediatric and young adult IBD patients have a low risk for complications and hospitalization, regardless of IBD treatment. We believe that this experience is encouraging and allows for safe counseling regarding treatment options and school attendance in pediatric and young adult IBD patients.

Abstract
INTRODUCTION Patients with elderly-onset inflammatory bowel disease were previously associated with a less aggressive course of the disease. However, there are conflicting data that need further validation. We aimed to determine the association between age at diagnosis and the development of progressive disease in patients with Crohn's disease (CD) and ulcerative colitis (UC). METHODS This cohort study included patients with CD and UC followed in 6 secondary and tertiary care centers in mainland Portugal. Patients were divided into a derivation (80%) cohort and a validation (20%) cohort. The primary outcome was progressive disease. Logistic regression analysis, receiver operating characteristic curves, and the areas under the curve (AUC) were performed. Odds ratios with 95% confidence intervals (CIs) were estimated. RESULTS The derivation cohorts included 1245 patients with CD (68% with progressive disease) and 1210 patients with UC (37% with progressive disease), whereas the validation cohorts included 302 patients with CD and 271 patients with UC, respectively, with similar outcome proportions. In our final model, age at diagnosis older than 60 years was significantly associated with a lower risk of developing progressive disease (odds ratio 0.390, 95% CI 0.164-0.923, P = 0.032), with a high discriminative power (AUC 0.724, 95% CI 0.693-754) in patients with CD. However, according to this model, no significant associations were found between age at diagnosis and the risk of developing progressive disease in patients with UC. No differences were observed in the AUC values between the validation and the derivation cohorts. DISCUSSION Patients with elderly-onset CD, but not patients with UC, were associated with a less progressive course of the disease.

Abstract
Epstein Barr virus (EBV) primoinfection may contribute to the development of post-mononucleosis lymphomas in EBV-seronegative adult males with inflammatory bowel disease (IBD) under thiopurine therapy, but data on children are sparse. Knowledge of the EBV status may influence the type of surveillance and therapy in a group particularly vulnerable to the occurrence of EBV primoinfection. We aimed to determine the EBV status at diagnosis, the primoinfection rate, and complications in a pediatric Portuguese population with IBD. METHOD This was a retrospective analysis of clinical records of pediatric patients with IBD. Demographic data, EBV status, as well as clinical and therapeutic data on primoinfection were collected. RESULTS Of the 250 patients evaluated, 229 (91.6%) had documented EBV screening and 50.8% were male. Mean age ± SD was 13.0 ± 2.8 years at diagnosis and 14.7 ± 2.3 years at EBV screening. EBV IgG serology was positive in 76.0% of patients. A total of 218 patients had been on therapy with azathioprine at some point. The average length of exposure to azathioprine was 4 years, and 91 patients (39.7%) were on azathioprine at EBV assessment. EBV primoinfection was documented in 4 patients (1.6%), all females, 2 of whom were on azathioprine. Two presented clinical signs of infection and 2 were identified at diagnostic screening; the first 2 suspended azathioprine and the other 2 did not initiate it. CONCLUSIONS A significant proportion of pediatric Portuguese IBD patients are EBV-naïve. Systematic screening of EBV status enables the identification of patients at risk of primoinfection, and the occurrence of symptoms suggestive of acute EBV infection in seronegative patients should lead to rapid confirmation of the diagnosis. Timely diagnosis may allow the adjustment of therapeutic strategy sparing patients from potentially severe iatrogeny.

Abstract
Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), both in pediatric and in adult patients. Iron deficiency is the main cause of anemia in patients with IBD. Anemia is a clinically relevant comorbidity, with impact on patients' quality of life and it should be timely diagnosed and adequately treated. Currently, an active treatment approach is the recommended strategy, with evidence showing efficacy and safety of intravenous iron formulations. However, evidence in pediatric age remains scarce and no clinical recommendations exist for the diagnosis and treatment of this particular age group. The present document represents the first national consensus on the management of anemia in pediatric IBD and is therefore particularly relevant. The authors anticipate that the proposed recommendations will be useful in daily clinical practice for diagnosing and managing iron deficiency and iron-deficiency anemia in the pediatric population with IBD.

Abstract
AIMS We aimed to describe the burden of rehospitalization in patients with inflammatory bowel disease (IBD), by evaluating rehospitalization rates, charges, and risk factors over 16 years. METHODS We performed a retrospective analysis of all hospital discharges with a primary diagnosis of IBD in public hospitals between 2000 and 2015 in mainland Portugal from the Central Administration of the Health System (ACSS)'s national registry. We collected data on patient, clinical, and healthcare charges. We used survival analysis to estimate the rate and risk factors of IBD-related rehospitalization. RESULTS We found that 33% (n = 15,931) of the IBD-related hospitalizations corresponded to rehospitalizations, which increased by 12% over 16 years. However, IBD rehospitalization rate per 100,000 IBD patients decreased 2.5-fold between 2003 and 2015. Mean IBD-related rehospitalization charges were €14,589/hospitalization-year in 2000 and €17,548 /hospitalization-year in 2015, with total rehospitalization charges reaching €3.1 million/year by 2015. Overall, the 30-day rate of rehospitalization was 24% for Crohn's disease (CD) and 22.4% for ulcerative colitis (UC). Novel risk factors for rehospitalization include penetrating disease in CD patients {hazard ratio (HR) 1.34 [95% confidence interval (CI) 1.20-1.51], p < 0.001} and colostomy in UC patients [HR 2.84 (95% CI 1.06-7.58)]. CONCLUSION IBD-related rehospitalization should be closely monitored, and efforts to reduce its risk factors should be made to improve the quality of care and, consequently, to reduce the burden of IBD.

Abstract
Background Over the last decades, the use of gastrointestinal (GI) endoscopic procedures has been increased in children worldwide, allowing the early diagnosis and therapeutic intervention in multiple GI diseases. Aims and Methods In order to evaluate the appropriateness and the diagnostic yield of initial GI endoscopic techniques in children in a Portuguese tertiary hospital, we performed a retrospective cohort study during a 12-month period. Results A total of 308 procedures were performed in 276 patients; the median age was 11 years and 50.4% were males. Esophago-gastro-duodenoscopy (EGD) corresponded to 81.8% of the procedures and ileo-colonoscopy (IC) to the remaining; 11.6% of the patients underwent both EGD and IC. Overall, 51.3% of the exams showed abnormal macroscopic findings, and 69.6% showed histopathological signs of disease, with IC showing significantly more positive results than EGD (p < 0.05). Considering the different indications independently, abnormal serology for celiac disease, suspected ingestion of foreign bodies, suspected inflammatory bowel disease, and food impaction were frequent in our population; and in the majority of the cases, the suspected diagnosis was confirmed: celiac disease, ingestion of foreign bodies, inflammatory bowel disease, and eosinophilic esophagitis, respectively. On the other hand, despite the high frequency of epigastric pain in this population, only nearly one-third of the patients showed abnormal histological findings. The final diagnosis was established in 63% of the patients, and 39.1% initiated the new treatment. Discussion Our results emphasize the importance of endoscopic procedures, especially IC, in the diagnosis of GI diseases in pediatric patients, as well as the careful choice of the endoscopic techniques in those with less specific symptoms, as chronic abdominal pain. In this particular situation, given the proportion of cases that may be due to functional disease, good characterization of the clinical context is needed, and endoscopy should be reserved for a second-line approach. Conclusion It is important to monitor and examine the endoscopic techniques as an index of quality criteria for clinical practice.

Abstract
BACKGROUND & AIMS We performed a systematic review of changes in fecal and colon microbiomes of patients with inflammatory bowel diseases (IBDs) receiving treatment with monoclonal antibodies against tumor necrosis factor, integrins, or cytokines. We explored associations among microbiome composition and functions (at baseline and throughout the treatment) and therapy-related outcomes to determine whether colon or fecal microbiomes might be used as biomarkers of response to therapy. METHODS We searched the PubMed, Web of Science, and Science Direct databases through February 2019 for studies of associations among the microbiomes of fecal or colon samples, biologic therapies, and IBDs. We used the critical appraisal skills program checklist to assess the quality of the study methods. RESULTS From the 787 citations identified, 10 studies met the inclusion criteria. Changes in microbiomes of fecal or colon samples after treatment did not differ significantly among biologic agents; all produced decreases in relative abundances of Escherichia and Enterococcus and increases in genera that produce short-chain fatty acids. Fecal or colon microbiomes of patients who responded to therapy with antagonists of tumor necrosis factor or interleukins had higher α-diversity and increased relative abundances of different genera (Faecalibacterium, Roseburia, or Clostridium) from the Clostridiales order, either at baseline or during follow-up evaluation. Patients in remission after treatment with antibodies against integrins had decreased abundances of Roseburia. CONCLUSIONS In a systematic review of 10 studies, we found evidence for consistent changes in microbiomes of fecal and colon samples from patients with IBD who responded to treatment with biologic agents. Prospective studies are needed to determine what changes are associated significantly with treatment, whether these changes are causes or effects of response, or whether the composition of the intestinal microbiome can be used to select treatments for patients with IBD.

Abstract
BACKGROUND Chronic granulomatous disease (CGD) is a primary immunodeficiency due to a malfunction of NADPH oxidase. It is characterized by recurrent and severe infections caused by catalase-positive microorganisms and autoinflammatory manifestations. Recently, there has been described an NCF4 gene variant that causes a deficiency of p40phox, a subunit of NADPH oxidase. Patients with this deficiency appear to have a less severe clinical form as compared to classic CGD. CASE A 15-year-old girl with vulvar lichen planus since she was 2 years old and suspected Crohn's disease (CD) was first seen at our hospital. At the age of 12 years, she had been submitted to sacrococcygeal cyst exeresis, without cicatrization of the surgical wound and extension of the lesion to the perianal area. The diagnosis of CD was questioned, and the patient underwent an endoscopic and radiologic assessment, which was normal. A skin biopsy from the perianal area revealed a granuloma; thus, CD with isolated perianal disease was assumed. After several different treatments including antibiotics, infliximab, and adalimumab, the perianal lesion persisted, with no associated gastrointestinal symptoms. Therefore, the hypothesis of an immunodeficiency was considered. An immunologic and genetic study revealed reduced oxidative burst in the phorbol myristate acetate test, with diminished reactive oxygen species production and a homozygous mutation in the NCF4 gene. The adolescent started prophylactic trimethoprim-sulfamethoxazole and became asymptomatic. CONCLUSIONS The present case highlights that alternative diagnoses to CD must be considered in the presence of isolated perianal disease with granulomatous inflammation, especially when the disease is refractory to conventional CD therapy.

Abstract
Hidradenitis suppurativa (HS) is a chronic and recurrent inflammatory disease characterized by the presence of painful and deep inflammatory lesions usually located in intertriginous areas. It rarely occurs in children, especially in prepubertal age. Treatment for HS in this age group is challenging considering the scant data available and the risk of adverse effects in younger patients. We report the case of a 10-year-old girl with Hurley III HS, refractory to multiple topical and systemic therapies. After introducing adalimumab, there was significant improvement of the skin lesions and therefore in the child's quality of life.

Abstract
INTRODUCTION In this study, we aimed to determine the hospitalization rates of Inflammatory Bowel Disease (IBD) in a southern-european country and its associated charges over a period of 16 years. METHODS We identified all discharges with a primary diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) between 2000 and 2015 in data provided by the Central Administration of Health Services (ACSS). National estimates of hospitalization rates were assessed and adjusted to gender, age, population, and hospitalizations. Hospitalization charges were also assessed. RESULTS There were an estimated 31 358 and 16 669 discharges for CD and UC, respectively. From 2000 to 2015, hospitalization rates per 100000 habitants increased for CD (8.4-11.2) and remained stable for UC (4.4-4.9). The hospitalization rate for IBD increased slightly over time (12.8 per 100 000 habitants in 2000 and 16.1 in 2015). Annual total hospitalization charges amounted to 4.0M€ in 2000 and 5.7M€ in 2015. This increase was mainly due to a rise in the total expenses of CD-related hospitalizations. CONCLUSION CD hospitalization rates per 100000 inhabitants increased over time while remaining constant for UC. Hospitalization charges for IBD increased approximately 2.0M€ during the study period, representing an important burden in the national healthcare system.

Abstract
BACKGROUND AND AIMS Placebo effect in health-related quality of life [HRQoL] of inflammatory bowel disease [IBD] patients has been poorly characterised. This systematic review and meta-analysis aimed to assess: i] mean improvements in IBDQ [Inflammatory Bowel Disease Questionnaire] and SF-36 [36-Item Short Form Health Survey] scores among placebo-treated IBD patients; and ii] the proportion of placebo-treated patients achieving IBDQ-defined response and remission and correspondent odds ratios [OR]. METHODS Literature search was performed using four databases. Mean differences and ORs were computed using the random-effects model. Univariate and multivariate regressions were performed to evaluate the weight of different factors on the placebo effect. RESULTS From the 328 identified records 26 were included in the study, comprising 2842 placebo-treated IBD patients. Pooled mean differences on IBDQ following placebo administration were above the clinically meaningful improvement [≥16 points] in ulcerative colitis [UC] patients during the induction regimen (17.67; 95% confidence interval [CI]: 12.90, 22.44) and during maintenance in both Crohn's disease [CD] [27.60; 95% CI: 14.29, 40.91] and UC patients [27.50; 95% CI: 18.73, 36.27]. The treatment regimen was the only significant variable in multivariate analysis, with lower placebo-related IBDQ improvements during induction. Maintenance trials' inclusion criteria were also relevant. The proportions of placebo-treated patients achieving IBDQ-defined response and remission were 0.42 [95% CI: 0.49, 0.56] and 0.31 [95% CI: 0.28, 0.34], respectively, with 0.49 and 0.40 the ORs for response and remission. Significant improvements were also observed on SF-36 score. CONCLUSIONS Herein we prove that placebo effect on HRQoL is meaningful, providing insights about implications for clinical trials' design and interpretation and for IBD management.

Malignancy and mortality in paediatric-onset inflammatory bowel disease: a 3-year prospective, multinational study from the paediatric IBD Porto group of ESPGHAN. Aliment Pharmacol Ther 2018; 48:523-537.

Abstract
BACKGROUND Risk benefit strategies in managing inflammatory bowel diseases (IBD) are dependent upon understanding the risks of uncontrolled inflammation vs those of treatments. Malignancy and mortality in IBD have been associated with disease-related inflammation and immune suppression, but data are limited due to their rare occurrence. AIM To identify and describe the most common causes of mortality, types of cancer and previous or current therapy among children and young adults with paediatric-onset IBD. METHODS Information on paediatric-onset IBD patients diagnosed with malignancy or mortality was prospectively collected via a survey in 25 countries over a 42-month period. Patients were included if death or malignancy occurred after IBD diagnosis but before the age of 26 years. RESULTS In total, 60 patients were identified including 43 malignancies and 26 fatal cases (9 due to cancer). Main causes of fatality were malignancies (n = 9), IBD or IBD-therapy related nonmalignant causes (n = 10; including 5 infections), and suicides (n = 3). Three cases, all fatal, of hepatosplenic T-cell lymphoma were identified, all were biologic-naïve but thiopurine-exposed. No other haematological malignancies were fatal. The 6 other fatal cancer cases included 3 colorectal adenocarcinomas and 3 cholangiocarcinomas (CCAs). Primary sclerosing cholangitis (PSC) was present in 5 (56%) fatal cancers (1 colorectal carcinoma, 3 CCAs and 1 hepatosplenic T-cell lymphoma). CONCLUSIONS We report the largest number of paediatric-onset IBD patients with cancer and/or fatal outcomes to date. Malignancies followed by infections were the major causes of mortality. We identified PSC as a significant risk factor for cancer-associated mortality. Disease-related adenocarcinomas were a commoner cause of death than lymphomas.

Abstract
Biallelic loss-of-function (LOF) mutations of the NCF4 gene, encoding the p40phox subunit of the phagocyte NADPH oxidase, have been described in only 1 patient. We report on 24 p40phox-deficient patients from 12 additional families in 8 countries. These patients display 8 different in-frame or out-of-frame mutations of NCF4 that are homozygous in 11 of the families and compound heterozygous in another. When overexpressed in NB4 neutrophil-like cells and EBV-transformed B cells in vitro, the mutant alleles were found to be LOF, with the exception of the p.R58C and c.120_134del alleles, which were hypomorphic. Particle-induced NADPH oxidase activity was severely impaired in the patients' neutrophils, whereas PMA-induced dihydrorhodamine-1,2,3 (DHR) oxidation, which is widely used as a diagnostic test for chronic granulomatous disease (CGD), was normal or mildly impaired in the patients. Moreover, the NADPH oxidase activity of EBV-transformed B cells was also severely impaired, whereas that of mononuclear phagocytes was normal. Finally, the killing of Candida albicans and Aspergillus fumigatus hyphae by neutrophils was conserved in these patients, unlike in patients with CGD. The patients suffer from hyperinflammation and peripheral infections, but they do not have any of the invasive bacterial or fungal infections seen in CGD. Inherited p40phox deficiency underlies a distinctive condition, resembling a mild, atypical form of CGD.

Abstract
BACKGROUND AND AIMS The time course for the development of clinically significant hereditary diffuse gastric cancer (HDGC) is unpredictable. Little is known about the progression from preclinical, indolent lesions to widely invasive, aggressive phenotypes. Gastroendoscopy often fails to detect early lesions, and risk-reducing/prophylactic total gastrectomy (PTG) is the only curative approach. We present an HDGC family with early-onset disease in which clinical and histologic findings provided insight into the understanding of different HDGC phenotypes. METHODS The proband was diagnosed at age 18 years with widely invasive, metastatic DGC. CDH1 genetic testing identified a pathogenic, germline CDH1 variant (c.1901C>T, p.Ala634Val). Thirty family members were tested, and 15 CDH1 carriers were identified. RESULTS Six family members had PTG, with negative preoperative workup. The proband's 14-year-old sister is the youngest patient, reported to date, to have PTG after negative preoperative biopsy sampling. Intramucosal HDGC foci were detected in all PTG specimens (1-33). In contrast to the "indolent" phenotype of these foci, the aggressive DGC from the proband showed pleomorphic cells, absent E-cadherin expression, increased proliferation (Ki-67 index), and activation of oncogenic events (p53, pSrc and pStat3 overexpression). All family members had Helicobacter pylori gastritis. Cag-A-positive strains were detected in all specimens, except in the proband's sister. CONCLUSIONS HDGC is a heterogeneous disease regarding clinical behavior, endoscopic findings, histopathologic features, and immunophenotypic/molecular profile. The presence of bizarre, pleomorphic cells in endoscopic biopsy specimens is suggestive of advanced disease and should prompt clinical intervention. The involvement of a full multidisciplinary team is essential for the management of these patients.

Abstract
BACKGROUND AND AIMS Thiopurines are widely used in the management of inflammatory bowel diseases. However, their minimum effective dose and dose-response relationship remain undefined, and evidence about their use in clinical practice is mostly heterogeneous. This systematic review and meta-analysis aimed: i] to assess the clinical value of 6-thioguanine nucleotide thresholds; and ii] to compare mean 6-thioguanine nucleotide concentrations between patients in clinical remission vs. those with active disease. METHODS A systematic literature search was carried out using four databases. Statistical heterogeneity was assessed with the I2 statistic followed by subgroup and sensitivity analyses. Odds ratios were computed using the random-effects model. RESULTS A total of 1384 records were identified in the systematic search, of which 25 were retained for further analysis: 22 were used in the cut-off comparisons and 12 were used in the 6-thioguanine nucleotide mean differences analysis. The global odds ratio for remission in patients with 6-thioguanine nucleotide levels above the predefined thresholds was 3.95 (95% confidence interval [CI], 2.63-5.94; p < 0.001]. When considering the different thresholds individually, the odd ratios were significant for values above 235 pmol/8 × 108 and 250 pmol/8 × 108 red blood cells [2.25 and 4.71, respectively]. Mean 6-thioguanine nucleotide levels were higher among patients in clinical remission, with a pooled difference of 63.37 pmol/8 × 108 red blood cells [95% CI, 31.81-94.93; p < 0.001]. CONCLUSIONS This study reinforces the link between 6-thioguanine nucleotide levels and clinical remission in inflammatory bowel diseases, also exploring the validity of specific 6-thioguanine nucleotide thresholds to predict clinical outcomes.

Abstract
Introduction Biliary atresia is the main cause of death by hepatic failure and the main indication for liver transplant in children. This study aims to analyze the population with this diagnosis, treated between 2000 and 2015 at Hospital de São João. Material and Methods Descriptive, observational, and retrospective study, including the patients with biliary atresia, diagnosed and treated between January 1, 2000 and December 31, 2015. We analyzed epidemiologic, clinical, biochemical, and image data, as well as registered complications and present status. Results Eighteen patients were evaluated. The median age at time of Kasai portoenterostomy was 63 days of life, with better prognosis for those patients who had surgery before 72 days. The procedure was successful in 2/3 of cases. There was a significant association between recurrent cholangitis and survival. Five cases of transplant and 2 deaths, one of them after transplant, were registered. Survival with native liver was 77.8%, 72.2%, and 64.2% at 1, 5, and 10 years of follow-up, respectively. Discussion The presentation and evolution of patients was similar to other studies. However, there was a higher surgical success and survival rates at 5 and 10 years of follow-up than most series. Age at surgery and recurrence of cholangitis were the only factors significantly related to prognosis. Conclusion In spite of the low number of patients (1,125/year), our results were similar to those of other reference centers.

Abstract
Gastric mucosal heterotopia has been described in all levels of the gastrointestinal tract. Its occurrence in the rectum is uncommon. We report the case of a 4-year-old boy referred to Pediatric Gastroenterology for intermittent rectal bleeding for the past 2 years. Total ileocolonoscopy revealed a flat, well-circumscribed lesion of 4 cm, with elevated margins, localized at 10 cm from the anal verge. Histologic examination showed typical gastric mucosa of the oxyntic type. Treatment with proton pump inhibitors was started without resolution of the symptoms and, therefore, an endoscopic mucosal resection was performed. Heterotopic gastric mucosa represents a rare cause of rectal bleeding in children and endoscopic evaluation is fundamental for diagnosis. Although not usually performed in pediatric ages, endoscopic mucosectomy allows complete resolution of the problem avoiding surgery.

Abstract
Invasive Haemophilus influenzae type b (Hib) disease decreased dramatically after the introduction of conjugate vaccine in routine immunization schedules. We report a case of a fifteen-months-old girl, previously healthy and vaccinated, admitted in the emergency room with fever and vomiting. She was irritable and the Brudzinski's sign was positive. The cerebrospinal fluid (CSF) analysis showed pleocytosis and high protein level. Empiric intravenous antibiotics (ceftriaxone and vancomycin) were administered for suspected bacterial meningitis during 10 days. Serotyping of the Haemophilus influenzae strain found in CSF revealed a serotype b. After one year of follow-up no Hib meningitis sequelae were noted. Despite vaccination compliance and absence of risk factors, invasive Hib disease can occur due to vaccine failure. Efforts to keep the low incidence of invasive Hib disease should be directed to the maintenance of high vaccination coverage rates, combined with the notification and surveillance strategies already implemented in each country.

Abstract
Introduction Inflammatory bowel disease may cause both intestinal and extraintestinal manifestations. Respiratory symptoms in ulcerative colitis are rare and tracheal involvement is exceedingly rare in children. Case 1 Sixteen year-old female with a 4-week-complaint of abdominal pain, bloody diarrhea, fever and cough. The investigation was consistent with the diagnosis of concomitant ulcerative colitis/coinfection to Escherichia coli. On day 4 respiratory signs persisted so azithromycin and inhaled corticosteroids were added. By day 6 she progressed to respiratory failure and was diagnosed with necrotic tracheitis so started on intravenous steroids with fast clinical improvement. Case 2 Twelve-year-old male adolescent with ulcerative colitis and sclerosing cholangitis started dry cough and throat pain 10 days after diagnosis. Laboratory investigations showed increased inflammatory signs and normal chest X-ray. He started treatment with azithromycin without clinical improvement and on day five he presented dyspnea and fever. Laryngeal fibroscopy suggested tracheitis and so systemic steroids where added with fast clinical and analytic improvement. Discussion Tracheitis should be suspected if there are persistent respiratory symptoms even when exams are normal. Early recognition and early treatment are essential for a good prognosis preventing progression to respiratory failure.

Abstract
Introduction Aspiration or ingestion of foreign bodies may occur during dental procedures. Diagnosis and management of these accidents is sometimes challenging. The authors present a small series of clinical cases: Case 1 Adolescent observed due to suspected accidental bracket ingestion, not visible on x-ray, removed by upper digestive endoscopy. Case 2 Adolescent observed after accidental ingestion of a dental file. Conflicting results in image exams and absence of object progression led to enteroscopy for extraction. Case 3 Adolescent observed due to accidental ingestion of a surgical blade, visualized on image study but not accessible by endoscopy, resulting in latter spontaneous elimination. Discussion Image study is frequently useful when metallic object ingestion is suspected, but has some limitations. In some cases, mucosal protections must be used during removal procedures. Prevention of such accidents is the best approach, using appropriate protections to secure airway and digestive tract during dental procedures.

Abstract
UNLABELLED Neurologic manifestations are present in a reasonable proportion of adult celiac patients and can be the first sign of gluten sensitivity. In children, the risk of neurological complications is lower, and gluten sensitivity with neurological presentation seems to be rare. We report a case of gluten sensitivity with severe neurological presentation in a 3-year-old girl. In the absence of gastrointestinal symptoms, the presence of white matter lesions in cerebral magnetic resonance imaging suggested an acute disseminated encephalomyelitis. Recurrence of neurologic symptoms and cerebral lesions over a long period of time made the authors consider an autoimmune/inflammatory systemic disease. IgA anti-transglutaminase (TG) 2 was elevated and duodenal biopsy confirmed the presence of enteropathy. A gluten-free diet led to complete resolution of neurological manifestations and arrest of white matter lesions progression. CONCLUSION In children with unclear neurologic manifestations with probable autoimmune etiology, anti-TG2 autoantibody titers should be determined considering the possibility of gluten sensitivity. Gluten-free diet remains the only effective treatment reported to date and, therefore, should be recommended to all patients with gluten sensitivity despite the type of manifestations. More studies, focusing on neurological manifestations and its response to gluten-free diet, are needed.

Abstract
BACKGROUND The combination of the severity of pediatric-onset inflammatory bowel disease (IBD) phenotypes and the need for intense medical treatment may increase the risk of malignancy and mortality, but evidence regarding the extent of the problem is scarce. Therefore, the Porto Pediatric IBD working group of ESPGHAN conducted a multinational-based survey of cancer and mortality in pediatric IBD. METHODS A survey among pediatric gastroenterologists of 20 European countries and Israel on cancer and/or mortality in the pediatric patient population with IBD was undertaken. One representative from each country repeatedly contacted all pediatric gastroenterologists from each country for reporting retrospectively cancer and/or mortality of pediatric patients with IBD after IBD onset, during 2006-2011. RESULTS We identified 18 cases of cancers and/or 31 deaths in 44 children (26 males) who were diagnosed with IBD (ulcerative colitis, n = 21) at a median age of 10.0 years (inter quartile range, 3.0-14.0). Causes of mortality were infectious (n = 14), cancer (n = 5), uncontrolled disease activity of IBD (n = 4), procedure-related (n = 3), other non-IBD related diseases (n = 3), and unknown (n = 2). The most common malignancies were hematopoietic tumors (n = 11), of which 3 were hepatosplenic T-cell lymphoma and 3 Ebstein-Barr virus-associated lymphomas. CONCLUSIONS Cancer and mortality in pediatric IBD are rare, but cumulative rates are not insignificant. Mortality is primarily related to infections, particularly in patients with 2 or more immunosuppressive agents, followed by cancer and uncontrolled disease. At least 6 lymphomas were likely treatment-associated by virtue of their phenotype.

Abstract
INTRODUCTION Gastroesophageal reflux is a common but usually innocuous condition in children. However, in the presence of Gastroesophageal reflux disease, the surgical treatment (open or laparoscopic) may be indicated. This study aimed to evaluate the feasibility, effectiveness and safety of laparoscopic antireflux surgery (Nissen fundoplication) with emphasis in infants. MATERIAL AND METHODS Children with gastroesophageal reflux proposed for laparoscopic antireflux surgery between January 2006 and December 2012 in a pediatric surgery department of a university hospital were studied. A descriptive and comparative analysis was conducted with regard to age (group I: <1 year, group II: 1-3 years, group III: > 3 years) and presence of comorbidities. Demographics, symptoms, comorbidities, operative indications, perioperative and postoperative outcome were assessed. The statistical significance level was set at 5%. RESULTS 55 children were proposed for surgery: 12 of group I, 15 group of II and 28 of group III. 50.9% had comorbidities (21 central nervous system disease and 7 esophageal atresia). In 52 (94.5%) cases, antireflux surgery was performed by laparoscopy. The procedure lasted 167 ± 42 minutes, with no significant differences according to age groups, although higher in those with central nervous system disease. With a follow-up of 35.5 ± 23.9 months, the following complications occurred: gas-bloat syndrome, dumping or dysphagia in 8 cases (15.7%) and paraesophageal hernia in 2 cases (3.9%), with no significant differences between groups; there was clinical recurrence with reoperation in 2 cases. CONCLUSION Laparoscopic Nissen fundoplication is a feasible and effective procedure, with minimal morbidity, including in infancy.

Abstract
AIM The appropriate management of achalasia in children remains debatable. The present study aimed to evaluate the outcome of laparoscopic Heller myotomy by assessing short- and mid-term issues. METHODS Children submitted to surgery from 2002 to 2010 were included. Surgery was proposed after failure of endoscopic dilatations. All patients underwent esophagocardiomyotomy (Heller) plus anterior fundoplication (Dor) by laparoscopy. Demographics, presentation symptoms and perioperative details were analyzed. The outcomes were assessed both by medical records and the application of a 14 items (score 0-worst to 4-best/normal) self-evaluation questionnaire (modified GIQLI - covering only upper gastrointestinal symptoms). RESULTS Six patients (5 males) with a median age of 12.2 years (range: 0.8-14.2) were submitted to surgery. The presenting symptoms were: dysphagia (83.3%), weight loss (50%), vomiting (33.3%), chronic cough (33.3%), and chest pain (16.7%). All patients were operated on by laparoscopy with no conversions; there were no intra or postoperative complications. At a median follow-up of 5 years (range: 2-10) none of the patients were re-operated. Five patients have normal eating habits; the remaining case presented recurrent episodes of dysphagia requiring regular endoscopic dilatations (every 6 months). The total GIQLI presented a mean score of 49.3 (range, 45-52) representing 88.1% of the theoretical maximum. The score for frequency of dysphagia episodes was 1.6 +/- 1.4; all patients scored 3 for the grade of dysphagia. CONCLUSIONS Laparoscopic Heller myotomy is effective and safe for achalasia in children, offering a good and durable quality of life; although frequent, the dysphagia episodes were mild.

Celiac disease in first degree relatives of celiac children. ARQUIVOS DE GASTROENTEROLOGIA 2013; 49:204-7. [PMID: 23011243 DOI: 10.1590/s0004-28032012000300007] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Accepted: 05/16/2012] [Indexed: 12/31/2022]
Abstract
CONTEXT The first degree relatives of celiac patients represent a high risk group for the development of this disorder, so their screening may be crucial in the prevention of long-term complications. OBJECTIVE In order to determine the prevalence of celiac disease in a group of first degree relatives of children with proven gluten intolerance, we conducted a prospective study that consisted in the screening of celiac disease, using a capillary immunoassay rapid test that allows a qualitative detection of IgA antibody to human recombinant tissue transglutaminase (IgA-TTG). METHODS When the screening test was positive subjects were advised to proceed with further investigation. The screening test was performed in 268 first degree relatives (143 mothers, 89 fathers, 36 siblings) corresponding to 163 children with celiac disease. RESULTS Screening test was positive in 12 relatives (4.5%), of which 1 refused to continue the investigation. In the remaining 11 relatives celiac disease was diagnosed in 7 cases (2.6%, 5 mothers, 2 fathers) who had a median age of 39 years (27-56 years), mild gastrointestinal symptoms, high titre of IgA-TTG and histology abnormalities confirming the diagnosis. All these patients are currently on a gluten-free diet. CONCLUSION The prevalence of celiac disease among first degree relatives (2.6%) was 5 times higher than that in the general population. Although the recommendations for screening asymptomatic high risk groups, such as first degree relatives, are not unanimous the early diagnosis is crucial in preventing complications, including nutritional deficiency and cancer.

Abstract
BACKGROUND & PURPOSE Despite potential advantages of gastric transposition there are some concerns about this surgical technique of esophageal substitution in children. In the current study the morbidity and functional outcome are surveyed in a series of patients undergoing gastric transposition due to extensive post-corrosive esophageal strictures. METHODS Retrospective analysis of children proposed for esophageal replacement from September 2003 through April 2007 after endoscopic dilations failure. Demographic and pathological features, intra and postoperative complications and clinical outcome were assessed. Continuous variables are expressed as median [range]. RESULTS There were six children (age: 4.3 [2.5;14.4] years) with esophageal structures secondary to corrosive alkali ingestion; five had been submitted to dilation (n = 8 [7;27]) and one had undergone gastrostomy. Esophagectomy without thoracotomy plus gastric transposition were uneventfully performed in all cases. There was no mortality. On postoperative course there was one hypertensive pneumothorax and one pneumonia. With a follow-up of 50 [38;80] months, two children experienced mild dysphagia that was promptly solved by one or two sessions of dilations of esophagogastric anastomosis; both weight and height were between 5th and 75th centiles; none presented gastrointestinal or recurrent respiratory symptoms, anemia or substitute dilation. CONCLUSION. Transhiatal esophagectomy with gastric transposition in posterior mediastinum presented low morbidity and excellent functional outcome with no impairment of growth or respiratory function, at least on short/medium term.

Abstract
Omalizumab is currently used in severe asthma and has been tried in other allergic disorders. The authors report two patients with multiple food allergies and eosinophilic esophagitis on a very restrictive diet who have been treated with omalizumab, in order to improve food intolerance--the major distressing factor in their lives. The patients significantly improved in the reported symptoms. However, no improvement was seen regarding esophageal endoscopy and histology. Given the poor histological and endoscopy response, eosinophilic esophagitis persistence is unlikely to be IgE dependent. Omalizumab may improve the quality of life of patients with severe food allergy by improving symptoms, but it does not appear to change endoscopic and histological features of eosinophilic esophagitis in a short follow-up.

Abstract
We report a 9-month-old male patient with autoimmune enteropathy treated with intravenous methylprednisolone who developed firm, red, subcutaneous nodules 20 days after abrupt steroid interruption. The diagnosis of poststeroid panniculitis (PSP) was made based on clinical and histological grounds. PSP is an unusual complication of systemic corticosteroid therapy, which might occur following rapid steroid tapering or withdrawal. Physicians should be aware of this rare condition and distinguish it from other causes of erythematous subcutaneous nodules and plaques in children.

Abstract
A 2-month-old female patient presented an extensive bilateral parotid hemangioma (PH) focally ulcerated. Additionally, hepatic ultrasonography revealed a hemangioendothelioma located at right lobe. She was treated with oral prednisolone (3 mg/kg/day) during 10 months with clinical improvement of PH, despite failure to thrive and arterial hypertension. However, regrowth of the lesion occurred after discontinuation of oral steroid. Propranolol hydrochloride (2 mg/kg/day divided into two doses) was then started and maintained for 16 months, with marked involution of the hemangioma and with no systemic side effects during treatment course. Curiously, also the liver hemangioendothelioma completely resolved after starting propranolol. PH is a threatening cervicofacial segmental hemangioma that frequently proliferates after the year of age and needs long-term treatment. On the other hand, hepatic hemangioendotheliomas may be associated with cutaneous hemangiomas in some patients and their natural history is similar to these, although patients may die of associated conditions. As for other infantile hemangiomas, propranolol proved to be an effective, safe, and well-tolerated treatment for PH. Its role in liver hemangiomas and hemangioendotheliomas should also be taken into account.

Abstract
BACKGROUND NOD2/CARD15 was described as the first susceptibility gene to Crohn's disease (CD). Polymorphisms in the TNFA gene and in the IL1 gene cluster, which are associated with an enhanced chronic inflammatory response, may also play a role in the development of CD. The aim of this study was to determine the association of polymorphisms in the CARD15, TNFA, IL1B, and IL1RN genes with risk of development of CD and with the clinicopathological profile of CD patients. METHODS In a case-control study including 235 CD patients and 312 controls (929 controls for TNFA genotyping), the CARD15 (R702W, G908R, and 1007fs), TNFA (-308G/A and -857C/T), IL1B (-511C/T), and IL1RN (intron 2 variable number of tandem repeats) polymorphisms were genotyped. RESULTS We observed a significant association between CD and the CARD15 polymorphisms, with an odds ratio (OR) of 2.9 [95% confidence interval (CI), 1.9 to 4.6] for carriers of 1 variant allele and an OR of 11.8 (95% CI, 3.5 to 40.4) for carriers of 2 variant alleles. Patients with CARD15 polymorphisms had more frequently ileal or ileocolonic disease location, stricturing phenotype, abdominal surgery, and no extraintestinal manifestations. The TNFA-308A/A genotype was associated with susceptibility to CD with an OR of 3.0 (95% CI, 1.2 to 7.2). TNFA-308A/A homozygotes showed a higher frequency of erythema nodosum and arthritis, colonic disease location, and absence of abdominal surgery. No associations were found with the TNFA-857, IL1B-511, and the IL1RN VNTR polymorphisms. CONCLUSIONS These findings suggest that CARD15 and TNFA-308 genetic polymorphisms are associated with increased risk of CD displaying distinct clinicopathological profiles.

Abstract
BACKGROUND/PURPOSE Delayed gastric emptying (DGE) is frequent in patients with gastroesophageal reflux disease (GERD) and may require additional investigation. The current study assesses whether relative esophageal exposure, postprandial (PP) versus fasting, diagnosed by pH monitoring could predict DGE. METHODS Thirty patients with GERD underwent extended esophageal pH monitoring and were assigned as DGE or non-DGE according to scintigraphy. The PP to fasting ratio for reflux index, relative frequency of long episodes in PP, and distribution of the longest episode were used to assess the relative esophageal exposure. The effectiveness of these parameters to predict DGE was estimated; the cutoffs for continuous variables were chosen with receiver operating characteristics (ROC) curves and the probabilities were calculated using a logistic regression model. RESULTS The area under the ROC curve of PP to fasting ratio for reflux index was greater than that of relative frequency of long episodes in PP. There was a good equilibrium between sensitivity and specificity at a PP to fasting ratio of 1. A PP to fasting ratio greater than 1, ie, a reflux index in PP greater than in fasting, presented a sensitivity of 93% and a negative predictive value of 91%. The occurrence of the longest episode in PP had a specificity of 94% and a positive predictive value of 89%. A reflux index greater in PP plus a longest episode in PP presented a 94% probability of DGE; a reflux index greater in fasting plus a longest episode in fasting had a 95% probability of non-DGE. These combinations represented 60% of the series. CONCLUSIONS PP to fasting ratio for reflux index and distribution of the longest episode seem accurate to identify DGE; thus, additional investigation to assess gastric emptying may be avoided in the majority of patients.
