RESUMO

OBJECTIVES: To characterize the clinical course of acute pancreatitis (AP) in pediatric inflammatory bowel disease (IBD) patients compared to children with AP without IBD and to identify risk factors associated with AP among IBD patients. METHODS: This retrospective, single-center study compared clinical characteristics of children (<19 years) with AP with and without concomitant IBD who were hospitalized 2005-2019. We also conducted a risk factor analysis of AP development in pediatric IBD. RESULTS: Sixty-eight (54% males) patients with 120 episodes of AP were admitted at a median age of 15.3 years. Thirteen patients (14 episodes) had a co-diagnosis of IBD, representing 4% of our IBD patient population. The AP-IBD patients presented with lower amylase levels compared to the non-IBD patients (160 [interquartile range, IQR: 83-231] vs. 418 [IQR: 176-874] U/L, p > 0.01), all had a mild pancreatitis, and none required invasive intervention. The presumed etiology for AP in all IBD patients was IBD-related: IBD flare-up in five, side effects of medications in two, and undetermined in seven. The only risk factor for AP development among IBD patients was IBD-associated arthritis (23% vs. 3% for IBD-non-AP, p = 0.04), while extracolonic Crohn's disease and induction therapy with nutrition were negative risk factors (15% vs. 51%, p = 0.05, and 8% vs. 44%, p = 0.04, respectively). Other parameters, including disease type and medications, were nonsignificant. CONCLUSION: The clinical course of AP in pediatric IBD patients is mild. Only IBD-associated arthritis emerged as a risk factor for the development of AP, while, unexpectedly, IBD medication did not.

RESUMO

BACKGROUND: Data on oral vancomycin for primary sclerosing cholangitis (PSC)-associated inflammatory bowel disease (IBD) are limited. AIMS: Using data from the Paediatric PSC Consortium, to examine the effect of vancomycin on IBD activity. METHODS: In this retrospective multi-centre cohort study, we matched vancomycin-treated and untreated patients (1:3) based on IBD duration at the time of primary outcome assessment. The primary outcome was Physician Global Assessment (PGA) of IBD clinical activity after 1 year (±6 months) of vancomycin. We used generalised estimating equations (GEE) to examine the association between vancomycin and PGA remission, adjusting for IBD type, severity and medication exposures. Secondary outcomes included serum labs and endoscopic remission (global rating of no activity) among those with available data and also analysed with GEE. RESULTS: 113 PSC-IBD patients received vancomycin (median age 12.7 years, 63% male). The matched cohort included 70 vancomycin-treated and 210 untreated patients. Vancomycin was associated with greater odds of IBD clinical remission (odds ratio [OR] 3.52, 95% CI 1.97-6.31; adjusted OR [aOR] 5.24, 95% CI 2.68-10.22). Benefit was maintained in sensitivity analyses restricted to non-transplanted patients and those with baseline moderate-severe PGA. Vancomycin was associated with increased odds of endoscopic remission (aOR 2.76, 95% CI 1.002-7.62; N = 101 with data), and with lower CRP (p = 0.03) and higher haemoglobin and albumin (both p < 0.01). CONCLUSION: Vancomycin was associated with greater odds of IBD clinical and endoscopic remission. Additional, preferably randomised, controlled studies are needed to characterise efficacy using objective markers of mucosal inflammation, and to examine safety and define optimal dosing.

RESUMO

BACKGROUND: Wilson disease is caused by pathogenic variants in the ATP7B gene which encodes a copper-transporting ATPase. AIMS: Describe a common founder pathogenic variant among Bukharan Jews and to assess its prevalence, clinical features, and outcome. METHODS: The cohort consisted of patients of Bukharan Jewish descent diagnosed with Wilson disease at a tertiary pediatric medical center in 2013-2018. Clinical and genetic data were collected and analyzed. RESULTS: Six patients from 4 unrelated families who were homozygous for the c.3784G > T p.(Val1262Phe) pathogenic variant in ATP7B were identified. Five presented with elevated aminotransferase levels, and one, with acute liver failure. Mean age at diagnosis was 8.7 years (5-12.5). Serum ceruloplasmin level was extremely low in all patients (1.9-7 mg/dL; mean 3.2(. The variant was identified in a heterozygous state in 5/153 Bukharan Jews; 2/33 from our local exome database and 3/120 healthy unrelated Bukharan Jews in another cohort, for an estimated carrier frequency of ∼1:30. CONCLUSIONS: We report a common founder pathogenic variant in the ATP7B gene among Bukharan Jews associated with severe early-onset Wilson disease. Given the clinical severity, high frequency of the variant, and being a treatable disease, its inclusion in pre-symptomatic screening in the Bukharan Jewish community should be considered. Furthermore, WD should be part of future genetic newborn screening programs in Israel and worldwide, to enable early treatment and prevention of future life-threatening complications.

RESUMO

AIM: Implementing genetic analyses have unraveled rare alterations causing early-onset obesity and complications, in whom treatment is challenging. We aimed to report on the effects of adjuvant off-label therapy with liraglutide, glucagon-like peptide-1 analogue (GLP-1a), in rare genetic diagnoses. METHODS: Case scenarios and review of the literature. RESULTS: Case 1: Nine-year-old boy with early-onset severe obesity and nonalcoholic fatty liver disease (NAFLD) due to a homozygous mutation in the MC4R gene deteriorated under lifestyle change and metformin therapy [at 10.5 years: body mass index (BMI) 51.2kg/m2, 226% of the 95th percentile, fat percentage (FP) 65% and muscle-to-fat ratio (MFR) z-score of -2.41]. One year of liraglutide treatment halted progressive weight gain [BMI 50.3kg/m2, 212% of the 95th percentile, 63.7% FP and MFR z-score of -2.34], with biochemical improvement. Case 2: Twelve-year-old boy with obesity presented with diabetes and progressive NAFLD. Exome analysis revealed two heterozygous mutations compatible with monogenic diabetes (HNF1A) and familial hypercholesterolemia (LDLR). Lifestyle modifications resulted in clinical and laboratory improvement (BMI 87th percentile, 32.8% FP, MFR z-score of -1.63, HbA1c 5.5%) without the expected recovery in liver transaminases. Liraglutide treatment augmented the improvement in weight status (BMI 68th percentile, 22.6% FP, MFR z-score of -1.13) with normalization of liver transaminases. Case 3: Nineteen-year-old male with spinal muscular atrophy type 3 presented with sarcopenic obesity and comorbidities. Treatment strategy included dietary counseling and multiple drug therapies (metformin, anti-hypertensive and statins). Liraglutide therapy led to a gradual recovery of metabolic complications allowing tapering-down other medications. CONCLUSIONS: Considering the pleiotropic effects of GLP1-a beyond BMI reduction, this treatment modality may serve as a game changer in challenging cases.

RESUMO

AIM: Temporal changes in common pathogens that cause clinical dysentery have been described in Europe. We aimed to describe the distribution of pathogens and their antibiotic resistance in hospitalised Israeli children. METHODS: This study retrospectively studied children hospitalised for clinical dysentery, with or without a positive stool culture, from 1 January 2016 to 31 December 2019. RESULTS: We diagnosed 137 patients (65% males), with clinical dysentery at a median age of 3.7 (interquartile range 1.5-8.2) years. Stools were cultured in 135 patients (99%), and the results were positive in 101 (76%). These comprised Campylobacter (44%), Shigella sonnei (27%), non-typhoid Salmonella (18%) and enteropathogenic Escherichia coli (12%). Only one of the 44 Campylobacter cultures was resistant to erythromycin and one of the 12 enteropathogenic Escherichia coli cultures was resistant to ceftriaxone. None of the Salmonella and Shigella cultures were resistant to ceftriaxone or erythromycin. We did not find any pathogens that were associated with a typical clinical presentation or laboratory results on admission. CONCLUSION: The most common pathogen was Campylobacter, in line with recent European trends. Bacterial resistance for commonly prescribed antibiotics was rare, and these findings support the current European recommendations.

RESUMO

OBJECTIVES: Societies' guidelines suggest routine tissue sampling in all children undergoing esophagogastroduodenoscopy and ileocolonoscopy, even in the absence of visible endoscopy abnormalities. We aimed to determine the agreement between endoscopic and histopathological findings in pediatric endoscopy and to assess the yield of routine biopsies from all sites. METHODS: Since January 2019, our endoscopy institute protocol has included routine biopsies sampling from the esophagus, stomach, duodenum, ileum, and colon in all diagnostic procedures. Agreement between tests was done using the kappa coefficient ( κ ). The study included all endoscopies performed during 2019. RESULTS: In total, 541 diagnostic endoscopies were done during the study period with 434 (80%) esophagogastroduodenoscopy and 107 (20%) were ileocolonoscopy. Compared to histology, endoscopic findings performance were: esophagus-sensitivity 33%, specificity 98%; stomach-sensitivity 60%, specificity 89%; duodenum-sensitivity 50%, specificity 97%; duodenal bulb-sensitivity 47%, specificity 89%; terminal ileum-sensitivity 82%, specificity 100%; colon-sensitivity 84%, specificity 96%. Assessment of concordance between endoscopic and histopathologic findings reveals an overall low level of agreement in esophagogastroduodenoscopy ( κ of 0.39, 0.51, 0.53, and 0.24 for the esophagus, stomach, duodenal second part, and bulb, respectively), and good agreement in ileocolonoscopy ( κ of 0.88 and 0.81 for the ileum and colon, respectively). CONCLUSIONS: Endoscopy findings are highly specific for histologic pathology, whereas the absence of findings correlates poorly with histologic findings. Ileocolonoscopy shows better agreement than esophagogastroduodenoscopy. Our data support routine tissue sampling in pediatric endoscopy.

RESUMO

Celiac disease clinical presentation is constantly changing. We set to determine the prevalence of elevated transaminases in newly diagnosed celiac patients and to evaluate this sub-group of patients for associated clinical and laboratory findings and assess their natural course of disease following therapeutic diet initiation. We conducted a prospective-observational study of all newly diagnosed pediatric celiac patients, between August 2016 and April 2018, in a pediatric gastroenterology clinic. Clinical data, anthropometrics, and blood test results were recorded at diagnosis and at 3, 6, and 12 months, respectively, of follow-up. We compared patients with normal and elevated transaminases at diagnosis. ALT threshold was set at 24 U/l. Of 125 newly diagnosed celiac patients, 31 (24.8%) had elevated ALT at diagnosis; two (1.6%) with over 3 × ULN. Patients with elevated ALT at diagnosis were significantly younger (mean age 5.5 (SD 3.4) vs. 7.3 (SD 3.7) years, p < 0.01) and more commonly presented with diarrhea (32.3% vs. 14.9%, p = 0.03). Eighty percent of patients with elevated ALT levels normalized their ALT within 3 months and all within 1 year. Following gluten-free diet initiation, patients with elevated ALT had similar clinical course, growth, serology normalization rate, and laboratory results, compared to patients with normal ALT over a 1-year follow-up. A single patient was simultaneously co-diagnosed with celiac disease and autoimmune hepatitis.Conclusion: Clinically significant ALT abnormalities are rare among newly diagnosed pediatric celiac patients. Significant elevations failing to normalize on a gluten-free diet should raise concern of a concomitant primary liver disease and warrant further investigations. What is Known: • Elevated liver enzymes may be an extra-intestinal manifestation of celiac disease. • Reported prevalences of ALT elevations among children with a new diagnosis of celiac disease ranges between 5 and 40%. What is New: • ALT elevations are present in 25% of children with a new diagnosis of celiac disease. • Significant elevations (>3 × ULN) are rare (1.6%). • Elevated liver enzymes are associated with earlier age at diagnosis. • The natural history of patients with elevated liver enzymes at diagnosis is comparable to those without.

RESUMO

The role of a positive family history in pediatric inflammatory bowel disease (IBD) in the era of biologic therapy has not been elucidated. We retrospectively reviewed the medical records of children with IBD and retrieved demographic and clinical characteristics, including the presence of a positive family history of IBD, IBD phenotype, disease course, and therapy. Overall, 325 children (age range at diagnosis 11-15 years) were included, of whom 82 (25.2%) had a positive family history. Children diagnosed during 2016-2020 had a higher frequency of positive family history compared to those diagnosed during 2010-2015 (31.8% versus 20.7%, respectively, p = 0.024). Children with a positive family history had a higher risk for a stricturing phenotype than those with a negative family history (11.3% versus 2.8%, respectively, p = 0.052). They more often received nutritional therapy (53.7% versus 36.6%, p = 0.007) and less often received corticosteroids (36.6% versus 52.7%, p = 0.012). More children with a negative family history needed intensification of biologic therapy (p = 0.041).Conclusion: The rate of a positive family history of IBD in the pediatric IBD population is increasing. A positive family history may have some impact upon IBD phenotype but none on IBD outcome. What is Known: •Familial clustering of inflammatory bowel disease (IBD) has been reported in 5%-15% of IBD patients. •The investigation of the impact of a positive family history upon IBD characteristics and severity revealed conflicting results. What is New: •In this cohort of 325 children with IBD, 25.2% had a positive family history. •The rate of a positive family history of IBD in the pediatric IBD population is increasing. •A positive family history may have some impact upon IBD phenotype but none on IBD outcome.

RESUMO

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) can range from simple steatosis to steatohepatitis with or without fibrosis. The predictors for liver fibrosis and the effect of nutritional intervention on hepatic fibrosis in pediatric population are not well established. We aimed to investigate the predictors for liver fibrosis and the effects of short-term nutritional intervention on steatosis and fibrosis among obese adolescents with NAFLD. METHODS: Cross-sectional study among obese adolescents. Sociodemographic and clinical data were collected. Liver fibrosis was estimated by Shearwave elastography. All participants were recommended to consume a low carbohydrate diet and were followed biweekly. Blood tests and elastography were performed upon admission and repeated after 3 months. RESULTS: Fifty-seven pediatric patients were recruited (35 males, mean age 13.5±2.9 years, mean body mass index [BMI] 38.8±9.7). Liver fibrosis was diagnosed in 34 (60%) subjects, which was moderate/severe (F≥2) in 24 (70%). A higher BMI Z score and moderate/severe steatosis correlated with moderate/severe fibrosis (P < 0.05). Seventeen patients completed 3 months of follow-up and displayed a decrease in BMI Z score (from BMI Z score 2.6±0.5 before intervention to 2.4±0.5 after intervention), with a significant decrease in liver fibrosis (P = 0.001). CONCLUSION: Pediatric patients with high BMIs and severe liver steatosis are at risk for severe liver fibrosis. Nutritional intervention with minimal weight loss may improves hepatic fibrosis among the pediatric population. TRIAL REGISTRATION: TRN NCT04561804 (9/17/2020).

RESUMO

PURPOSE: The endoplasmic reticulum membrane complex (EMC) is a highly conserved, multifunctional 10-protein complex related to membrane protein biology. In seven families, we identified 13 individuals with highly overlapping phenotypes who harbor a single identical homozygous frameshift variant in EMC10. METHODS: Using exome, genome, and Sanger sequencing, a recurrent frameshift EMC10 variant was identified in affected individuals in an international cohort of consanguineous families. Multiple families were independently identified and connected via Matchmaker Exchange and internal databases. We assessed the effect of the frameshift variant on EMC10 RNA and protein expression and evaluated EMC10 expression in normal human brain tissue using immunohistochemistry. RESULTS: A homozygous variant EMC10 c.287delG (Refseq NM_206538.3, p.Gly96Alafs*9) segregated with affected individuals in each family, who exhibited a phenotypic spectrum of intellectual disability (ID) and global developmental delay (GDD), variable seizures and variable dysmorphic features (elongated face, curly hair, cubitus valgus, and arachnodactyly). The variant arose on two founder haplotypes and results in significantly reduced EMC10 RNA expression and an unstable truncated EMC10 protein. CONCLUSION: We propose that a homozygous loss-of-function variant in EMC10 causes a novel syndromic neurodevelopmental phenotype. Remarkably, the recurrent variant is likely the result of a hypermutable site and arose on distinct founder haplotypes.

RESUMO

AIM: More normal weight and overweight children are currently diagnosed with celiac disease (CD). We aimed to describe the relation between body mass index (BMI) and the clinical characteristics of paediatric CD and to determine the effect of a gluten-free diet (GFD) on BMI. METHODS: Data on all children diagnosed with CD during 7/2010-7/2019 with documented anthropometric data at diagnosis were retrospectively analysed. The children were divided into three groups according to BMI status at diagnosis: underweight, normal weight and overweight (BMIs <5%, 5%-85% and >85%, respectively). RESULTS: Of the 236 children [median age 7.87 (4.91-11) years] included in the study, 24 (10.1%) were underweight at diagnosis and 32 (13.6%) were overweight. Diarrhoea as the presenting symptom was significantly more common in the overweight group (p = 0.012), while short stature was more common in the underweight group (p = 0.002). Following a GFD had no significant effect on the children's BMI during a median follow-up of 15.7 (0-85) months, but there was a significant shift of patients between the BMI categories (p < 0.001). CONCLUSION: Although a shift of patients between the BMI categories was observed, following a GFD did not significantly affect the overall BMI in children with CD.

RESUMO

Inflammatory bowel disease (IBD) has been associated with underweight and malnutrition, but obesity may also serve as a negative prognostic factor. This study aimed to present the longitudinal course of height, weight, and body mass index (BMI) of children from IBD diagnosis to 18 months of follow-up, and to describe the impact of BMI on the clinical course of the disease. One hundred and fifty-two children were identified, of whom 85 had Crohn's disease (CD) and 67 had ulcerative colitis (UC). During a median (interquartile range) follow-up of 2.95 (1.73-4.5) years, weight and BMI Z-scores increased in the first 18 months since diagnosis in both the CD (P < 0.001) and UC (P < 0.028) groups. BMI in lower and upper quartiles at diagnosis was associated with higher risk of hospitalization (hazard ratio [HR] = 2.72, P = 0.021). In a multivariate analysis, BMI in the lower quartile at diagnosis and at 6, 12, and 18 months was associated with higher risk of disease exacerbation (HR = 2.36, 1.90, 1.98, and 2.43, respectively, P < 0.021), as was BMI in the upper quartile (HR = 2.59, 2.91, and 2.29, respectively, P < 0.013).Conclusion: BMI in the lower and upper quartiles at diagnosis and during follow-up was associated with a more severe disease course in children with IBD. What is Known: • Inflammatory bowel disease (IBD) has been associated with underweight and malnutrition. • The impacts of weight and body mass index (BMI) on the presentation and course of IBD have been mainly investigated in the adult population. What is New: • In the era of the obesity epidemic, this study identifies both low and high BMIs at diagnosis and at follow-up as a marker for poor outcome in pediatric IBD. • The results support using BMI as a predictor of IBD course and prognosis.

RESUMO

BACKGROUND AND AIMS: Disease progression in children with primary sclerosing cholangitis (PSC) is variable. Prognostic and risk-stratification tools exist for adult-onset PSC, but not for children. We aimed to create a tool that accounts for the biochemical and phenotypic features and early disease stage of pediatric PSC. APPROACH AND RESULTS: We used retrospective data from the Pediatric PSC Consortium. The training cohort contained 1,012 patients from 40 centers. We generated a multivariate risk index (Sclerosing Cholangitis Outcomes in Pediatrics [SCOPE] index) that contained total bilirubin, albumin, platelet count, gamma glutamyltransferase, and cholangiography to predict a primary outcome of liver transplantation or death (TD) and a broader secondary outcome that included portal hypertensive, biliary, and cancer complications termed hepatobiliary complications (HBCs). The model stratified patients as low, medium, or high risk based on progression to TD at rates of <1%, 3%, and 9% annually and to HBCs at rates of 2%, 6%, and 13% annually, respectively (P < 0.001). C-statistics to discriminate outcomes at 1 and 5 years were 0.95 and 0.82 for TD and 0.80 and 0.76 for HBCs, respectively. Baseline hepatic fibrosis stage was worse with increasing risk score, with extensive fibrosis in 8% of the lowest versus 100% with the highest risk index (P < 0.001). The model was validated in 240 children from 11 additional centers and performed well. CONCLUSIONS: The SCOPE index is a pediatric-specific prognostic tool for PSC. It uses routinely obtained, objective data to predict a complicated clinical course. It correlates strongly with biopsy-proven liver fibrosis. SCOPE can be used with families for shared decision making on clinical care based on a patient's individual risk, and to account for variable disease progression when designing future clinical trials.

RESUMO

BACKGROUND AND AIMS: Many children with primary sclerosing cholangitis (PSC) receive oral vancomycin therapy (OVT) or ursodeoxycholic acid (UDCA). There is a paucity of data on whether these medications improve outcomes. APPROACH AND RESULTS: We analyzed retrospective data from the Pediatric PSC Consortium. Children treated with OVT were matched 1:1:1 to those treated with UDCA or managed with observation (no treatment) based on the closest propensity score, ensuring similar baseline characteristics. Two hundred sixty-four patients (88 each with OVT, UDCA, or observation) had matching propensity scores and were similar in demographics, phenotype, immunosuppression, baseline biochemistry, and hepatic fibrosis. After 1 year in an intention-to-treat analysis, all outcome metrics were similar regardless of treatment group. In OVT, UDCA, and untreated groups, respectively: Gamma-glutamyltransferase normalized in 53%, 49%, and 52% (P = not significant [NS]), liver fibrosis stage was improved in 20%, 13%, and 18% and worsened in 11%, 29%, and 18% (P = NS), and the 5-year probability of liver transplant listing was 21%, 10%, and 12% (P = NS). Favorable outcome was associated with having a mild phenotype of PSC and minimal hepatic fibrosis. CONCLUSIONS: We presented the largest-ever description of outcomes on OVT in PSC and compared them to carefully matched patients on UDCA or no therapy. Neither OVT nor UDCA showed improvement in outcomes compared to a strategy of observation. Patients progressed to end-stage liver disease at similar rates. Spontaneous normalization of biochemistry is common in children receiving no therapy, particularly in the majority of children with a mild phenotype and an early stage of disease. Placebo-controlled treatment trials are needed to identify effective treatments for pediatric PSC.

RESUMO

BACKGROUND: Gastrointestinal endoscopy may be associated with pain and anxiety. Predictors for high pain scores after endoscopies in children are not known. The aim of our study was to identify risk factors for prolonged recovery and higher pain scores after gastrointestinal endoscopy in children. METHODS: All the children that were electively admitted for gastrointestinal endoscopies were included. We retrospectively collected demographic, clinical and endoscopic data as well as information on the recovery process. A numerical rating scale and the Faces, Legs, Activity, Cry, and Consolability Scale were used for pain scoring. RESULTS: During the study period (01/2016-10/2016), 284 children (median age 10.7 years, interquartile range 6.7-14.8) were recruited. In a univariate analysis, older age, higher pre-procedure pain scores, longer procedure durations, higher number of biopsies and longer recovery duration were associated with higher post-procedure pain scores. In a multivariate analysis higher pain scores before the procedure (OR 12.42, 95% CI 3.67-42, P < 0.001) and older age (OR 1.016, 95% CI 1.007-1.025, P < 0.001) were associated with higher pain scores after the procedure. Children with a higher pain score before the procedure also had a longer recovery period (OR 5.28, 95% CI (1.93-14.49), P = 0.001). CONCLUSION: Older age and higher pain score before the procedure were identified as predictors for higher pain score after pediatric gastrointestinal endoscopies. Children with these risk factors should be identified before the procedure in order to personalize their post-procedure management.

RESUMO

BACKGROUND: Functional abdominal pain (FAP) disorders are one of the most common gastrointestinal disorders in children. We aimed to define the association between obesity and functional abdominal pain (FAP) disorders and to assess differences between overweight/obese children and normal weight children with FAP disorders. METHODS: We conducted a retrospective study of children (2-18 years old) with a clinical diagnosis of FAP who were followed-up in our pediatric gastroenterology unit between 1/2016-10/2018. FAP disorders were defined according to the ROME IV criteria. Body mass index (BMI) percentiles were defined by CDC standards. Patients with BMIs ≥85th percentile were designated as being overweight/obese. A population control group was obtained from the 2015-2016 Israel national health survey. RESULTS: Data from 173 children with FAP disorders (median age 11.5 years, 114 females) were included. Seventy-one children (41%) were classified as having functional abdominal pain-NOS, 67 (38.7%) as having irritable bowel syndrome (IBS), and 35 (20.2%) has having functional dyspepsia. Fifty-three children (30.6%) were classified as being overweight/obese. Adolescents with FAP disorders had a significantly higher prevalence of overweight/obesity compared to controls (39.5% vs. 30%, respectively, p = 0.04). Children with FAP and overweight were older [12.4 (range 9.8-15.3) vs. 10.8 (7.4-14.1) years, p = 0.04] and had more hospitalizations due to FAP (20.8% vs. 7.6%, p = 0.01) compared to Children with FAP and normal weight. CONCLUSIONS: Adolescents with FAP had higher prevalence of overweight/obesity compared to controls. Future studies are warranted to raise awareness of weight issues in FAP and determine the effect of weight loss on FAP.

RESUMO

BACKGROUND: Natural history models for primary sclerosing cholangitis (PSC) are derived from adult patient data, but have never been validated in children. It is unclear how accurate such models are for children with PSC. METHODS: We utilized the pediatric PSC consortium database to assess the Revised Mayo Clinic, Amsterdam-Oxford, and Boberg models. We calculated the risk stratum and predicted survival for each patient within each model using patient data at PSC diagnosis, and compared it with observed survival. We evaluated model fit using the c-statistic. RESULTS: Model fit was good at 1 year (c-statistics 0.93, 0.87, 0.82) and fair at 10 years (0.78, 0.75, 0.69) in the Mayo, Boberg, and Amsterdam-Oxford models, respectively. The Mayo model correctly classified most children as low risk, whereas the Amsterdam-Oxford model incorrectly classified most as high risk. All of the models underestimated survival of patients classified as high risk. Albumin, bilirubin, AST, and platelets were most associated with outcomes. Autoimmune hepatitis was more prevalent in higher risk groups, and over-weighting of AST in these patients accounted for the observed versus predicted survival discrepancy. CONCLUSIONS: All 3 models offered good short-term discrimination of outcomes but only fair long-term discrimination. None of the models account for the high prevalence of features of autoimmune hepatitis overlap in children and the associated elevated aminotransferases. A pediatric-specific model is needed. AST, bilirubin, albumin, and platelets will be important predictors, but must be weighted to account for the unique features of PSC in children.

RESUMO

OBJECTIVE: To investigate patient factors predictive of gamma glutamyltransferase (GGT) normalization following ursodeoxycholic acid (UDCA) therapy in children with primary sclerosing cholangitis. STUDY DESIGN: We retrospectively reviewed patient records at 46 centers. We included patients with a baseline serum GGT level ≥50 IU/L at diagnosis of primary sclerosing cholangitis who initiated UDCA therapy within 1 month and continued therapy for at least 1 year. We defined "normalization" as a GGT level <50 IU/L without experiencing portal hypertensive or dominant stricture events, liver transplantation, or death during the first year. RESULTS: We identified 263 patients, median age 12.1 years at diagnosis, treated with UDCA at a median dose of 15 mg/kg/d. Normalization occurred in 46%. Patients with normalization had a lower prevalence of Crohn's disease, lower total bilirubin level, lower aspartate aminotransferase to platelet ratio index, greater platelet count, and greater serum albumin level at diagnosis. The 5-year survival with native liver was 99% in those patients who achieved normalization vs 77% in those who did not. CONCLUSIONS: Less than one-half of the patients treated with UDCA have a complete GGT normalization in the first year after diagnosis, but this subset of patients has a favorable 5-year outcome. Normalization is less likely in patients with a Crohn's disease phenotype or a laboratory profile suggestive of more advanced hepatobiliary fibrosis. Patients who do not achieve normalization could reasonably stop UDCA, as they are likely not receiving clinical benefit. Alternative treatments with improved efficacy are needed, particularly for patients with already-advanced disease.

RESUMO

OBJECTIVES: The course and evolution of pediatric acute pancreatitis (AP) is poorly understood. Prognostication models in children perform poorly and lack consensus. We aimed to identify predictors of AP severity, and the risk for AP recurrence. METHODS: We retrospectively studied all patients hospitalized with AP at a single tertiary center, between January 1995 and June 2016. Patient demographics and admission laboratory data were assessed for severity and recurrence prediction. RESULTS: A total of 68 patients accounting for a total of 117 (15 moderate-severe) AP episodes were reviewed. Patients with moderate-severe disease were significantly younger (median [interquartile range (IQR)] of 8.3 [4.0-14.4] vs 13.8 [8.1-16.0] years, P = 0.02). Young age at presentation was associated with odds ratio of 3.8 (confidence interval [CI] 1.2-12.1) for children younger than 12 years and 5.8 (CI 1.6-21.4) for children younger than 6 years for developing moderate-severe disease.Further subanalysis of the 59 patients with first-time AP episodes, demonstrated younger age (median [IQR] of 5.3 [2.9-10.4] vs 12.0 [6.3-15.8] years, P = 0.03) and elevated white blood cell count (median [IQR] of 22.8 [11.8-31.3] vs 11.0 [8.1-14.6] 10/L, P < 0.01) of patients with moderate-severe disease, conferring a risk for moderate-severe disease with odds ratio of 7.5 (CI 1.5-38.2) for children younger than 6 years and 5.3 (CI 1.1-25.4) for patients with white blood cell count >15 × 10/L, respectively. Fourteen (23.7%) of 59 patients with first-time episodes had recurrent AP. Analysis of the data at the primary episode failed to identify predictors to indicate future recurrence. CONCLUSIONS: In our cohort, only young age (<12 years) predicted AP severity. No parameters were identified to predict future development of AP recurrence.
