RESUMEN
Complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy (CHAPLE disease) is a lethal disease caused by genetic loss of the complement regulatory protein CD55, leading to overactivation of complement and innate immunity together with immunodeficiency due to immunoglobulin wasting in the intestine. We report in vivo human data accumulated using the complement C5 inhibitor eculizumab for the medical treatment of patients with CHAPLE disease. We observed cessation of gastrointestinal pathology together with restoration of normal immunity and metabolism. We found that patients rapidly renormalized immunoglobulin concentrations and other serum proteins as revealed by aptamer profiling, re-established a healthy gut microbiome, discontinued immunoglobulin replacement and other treatments and exhibited catch-up growth. Thus, we show that blockade of C5 by eculizumab effectively re-establishes regulation of the innate immune complement system to substantially reduce the pathophysiological manifestations of CD55 deficiency in humans.

INTRODUCTION: Low serum titer of anti-tissue transglutaminase (tTG) has been described in various conditions without any evidence of celiac disease (CD). Infectious agents have been suggested to trigger autoimmunity and promote the production of anti-tTG. The aim of this study was to investigate if there is a link between a positive celiac serology and concomitant Helicobacter pylori infection in children. METHODS: The data of 178 pediatric patients who underwent upper gastrointestinal endoscopy due to positive celiac serology were compiled. The patients whose histopathologic findings were not consistent with CD were followed on gluten-containing diet. The changes in the serum level of anti-tTG IgA on the follow-up were compared between H. pylori-infected and noninfected patients after the eradication of H. pylori. RESULTS: Of 155 patients who met the inclusion criteria, 119 (group 1) were diagnosed as CD, and duodenal histopathology of the remaining 36 children (group 2) was not compatible with CD. In group 2, 11 out of 36 (30.5%) patients were infected with H. pylori. After the eradication of H. pylori, anti-tTG IgA level either decreased or dropped below cutoff value in 9/11 (81%) patients while it was 20% in those who were not infected with H. pylori in the 6th month of the follow-up (p = 0.001). CONCLUSION: Our results suggest that H. pylori infection may be the cause of false or transient positive celiac serology. Thus, a positive celiac serology should be carefully interpreted in the presence of H. pylori infection before confirming the diagnosis of this life-long disease.

OBJECTIVES: It is not clear whether the characteristics of pediatric inflammatory bowel disease (IBD) differ between Eastern and Western countries. The aim of this study was to analyze the characteristics of PIBD in Turkey, according to the age at diagnosis. METHODS: The data of 176 children with IBD who were followed in our center were analyzed. Patients were divided into early (EO-IBD, onset at 2 to <10 years) and later-onset (LO-IBD, 10 to ≤17 years) IBD according to the age at diagnosis. Patients' data with ulcerative colitis (UC) and Crohn's disease (CD) were compared. RESULTS: Of 176 patients, 47 (26.7%) were diagnosed with EO-IBD. Patients with early-onset ulcerative colitis (EO-UC) had the highest rate of family history of IBD (17.6%). Pancolitis was the most common form of UC regardless of the age at onset. The rate of moderate-severe disease activity in later-onset UC (62.5%) was higher than in EO-UC (37.5%). A higher rate of extraintestinal manifestations was observed in EO-IBD patients, particularly in EO-UC (38.2%) than in LO-IBD patients. Patients with early-onset CD (EO-CD) had predominantly colonic involvement and nonstricturing, nonpenetrating disease behavior. The rate of perianal disease in patients with later-onset CD (LO-CD) (64.5%) was noticeably higher than those with EO-CD (23%). CONCLUSIONS: Our results suggest that patients with EO-UC represented a distinct phenotype with a mild disease activity, high rate of extraintestinal symptoms, and a high proportion of family history. The analysis of our IBD cohort also demonstrated remarkably high rate of perianal disease, particularly in patients with LO-CD.

Recent guidelines suggest non-biopsy serology-based approach for the diagnosis of celiac disease; however, there is no evidence-based data regarding noninvasive follow-up of mucosal healing. The aim of this study is to investigate the efficacy of serology in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. This is a validation study conducted at a university hospital. Patients who had biopsy proven celiac disease (Marsh III) at diagnosis, and had been followed-up for at least 12 months, were prospectively evaluated with duodenal biopsies. tTG-IgA and EMA tests were performed on the day of endoscopy. One hundred four patients with a mean age of 7.4 ± 4.02 years were included in the study. The sensitivity and specificity of tTG-IgA were 85.2% and 61% respectively, with a high negative predictive value (NPV) of 92.2% but a very low positive predictive value (PPV) of 43.4%. We found that a cutoff value of 68.5 U/mL for tTG-IgA had a sensitivity, specificity of 85.2% and 85.7% respectively. The AUC was 0.891. The sensitivity and specificity of EMA was 77.8% and 87% respectively, with a high NPV of 91.8% but low PPV of 67.7%. CONCLUSION: This study suggests that negative tTG-IgA and/or EMA can be used as an indicator of mucosal improvement in the follow-up of pediatric patients with celiac disease. However, positive serology (i.e., < 10 × ULN) may be misleading in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. WHAT IS KNOWN: ⢠The tissue transglutaminase IgA (tTG-IgA) and endomysium IgA (EMA) tests are widely used, sensitive and reliable diagnostic tests, but their role in monitoring adherence to dietary treatment in celiac patients has not yet been demonstrated. ⢠There is still no reliable and non-invasive marker of persistent villous atrophy or mucosal recovery. WHAT IS NEW: ⢠Negative celiac serology detected in the follow-up of pediatric patients with celiac disease was successful in demonstrating histopathological mucosal healing. ⢠Positive celiac serology, which is highly reliable in the diagnosis of celiac disease, has not been successful in reflecting mucosal status when used in the follow-up of pediatric patients with celiac disease.

BACKGROUND: Studies of monogenic gastrointestinal diseases have revealed molecular pathways critical to gut homeostasis and enabled the development of targeted therapies. METHODS: We studied 11 patients with abdominal pain and diarrhea caused by early-onset protein-losing enteropathy with primary intestinal lymphangiectasia, edema due to hypoproteinemia, malabsorption, and less frequently, bowel inflammation, recurrent infections, and angiopathic thromboembolic disease; the disorder followed an autosomal recessive pattern of inheritance. Whole-exome sequencing was performed to identify gene variants. We evaluated the function of CD55 in patients' cells, which we confirmed by means of exogenous induction of expression of CD55. RESULTS: We identified homozygous loss-of-function mutations in the gene encoding CD55 (decay-accelerating factor), which lead to loss of protein expression. Patients' T lymphocytes showed increased complement activation causing surface deposition of complement and the generation of soluble C5a. Costimulatory function and cytokine modulation by CD55 were defective. Genetic reconstitution of CD55 or treatment with a complement-inhibitory therapeutic antibody reversed abnormal complement activation. CONCLUSIONS: CD55 deficiency with hyperactivation of complement, angiopathic thrombosis, and protein-losing enteropathy (the CHAPLE syndrome) is caused by abnormal complement activation due to biallelic loss-of-function mutations in CD55.

BACKGROUND: An inverse association has been suggested between celiac disease (CD) and Helicobacter pylori (Hp) infection in children; however, there are inconsistent data. The purpose of this multi-center study is to evaluate the association between Hp and CD in childhood. METHODS: Children who underwent endoscopy between July 2016 and November 2017 in four pediatric gastroenterology centers were included in the study. Patients with a history of previous Hp eradication, antibiotic or acid-suppressive drug therapy in the last 4 weeks, and any underlying chronic disease were excluded. The presence of Hp infection was confirmed by both histopathology and the rapid urease test. The ones who had the diagnosis of CD were compared with the children who underwent endoscopy during the same period and had another diagnosis. Duodenal histopathology of children with CD was categorized according to the modified Marsh classification. RESULTS: Of 3056 endoscopies performed in the study period, 2484 cases were eligible for the study. A total of 482 CD patients (mean age: 9.71 ± 4.63 years, 58.5% girls) and 2060 controls (mean age: 9.92 ± 4.66 years, 54.6% girls) were included in the study. The rate of Hp infection was significantly lower in CD group (26.3% vs 50.1%, P < .01). The difference was prominent even in children younger than 6 years old (P < .01). There was no correlation between Hp infection and the modified Marsh scores in CD (P > .05). CONCLUSION: In this cross-sectional study, where Hp infection is common even in the pediatric population, the frequency of Hp infection was significantly lower in children with CD compared with the controls. Systematic cohort studies are necessary to clarify causal association between Hp infection and the development of celiac disease.

BACKGROUND AND OBJECTIVES: Bowel preparation (BP) for colonoscopy is a challenging procedure in children and different regimens have been used for this purpose. Polyethylene glycol (PEG) is the most preferred agent in recent years. The primary aim of this study was to evaluate the efficacy of 1-day PEG-3350 with bisacodyl (PEG-B) and comparing it with 3-day sennosides A+B. METHOD: In this prospective, randomized, and single-blinded study, children aged 2-18 years were included in the PEG-B group for 1 day or in Senna group for 3 days. The effectiveness of BP was assessed according to the Ottawa and Boston BP scales, compliance and adverse effects were also recorded. Pre- and post-preparation biochemistry were obtained for investigation of safety of both regimens. RESULTS: Successful BP was observed in 88.3% (n = 53/60) of PEG-B and 86% (n = 55/64) of Senna groups according to Boston scale, and it was 85% (n = 51/60) and 84.4% (n = 54/64), respectively, according to Ottawa scale. The cecal intubation rate was 96.7% (n = 58/60) in the PEG-B group and 93.8% (n = 60/64) in the Senna group. Ease of administration and disturbance in regular daily activities was better in the PEG-B group (p < 0.05). There was no major adverse event and biochemical abnormality in both groups. The correlation between Ottawa and Boston scales was found to be excellent (r2 = -0.954, p < 0.01). CONCLUSIONS: The efficacy, safety, and adverse effect profile of 1-day BP with PEG-B regimen was found to be similar to 3-day sennosides regimen, however, the PEG-B regimen had advantages such as short duration, ease of administration, and better patient comfort. Also, high correlation rate between the Boston and Ottawa scales in pediatric patients was remarkable.

BACKGROUND: It has been reported that 5-50% of patients with primary immune deficiencies (PID) may present with or develop gastrointestinal (GI) manifestations. OBJECTIVE: This study was aimed at analyzing GI and related endoscopic, histopathological findings in children with PID. METHODS: Children with PID who were evaluated by endoscopy between 2005 and 2016 were enrolled in this study. Demographic data, growth parameters, signs and symptoms at diagnosis were obtained. RESULTS: Of 425 children with PID, 195 had GI manifestations. Forty-seven of 195 children required endoscopic investigation, 30 (63.8%) were male, and the mean age was 7.7 ± 5 years. The rate of consanguinity was 61.7%, and the most common symptom was chronic diarrhea (57.4%). Seventy-two percent of the patients were malnourished. Giardia intestinalis was detected in 4, and Helicobacter pylori was confirmed in 8/45 (17.7%) patients. Non-celiac villous flatting was discovered in 15.5% of patients. Twelve patients were diagnosed as having immunodeficiency associated inflammatory bowel disease (IBD)-like colitis. CONCLUSIONS: PID may present with GI manifestations or develop during the course of the disease. Investigating immunodeficiency in patients with atypical GI symptoms can provide an appropriate therapeutic option, and an improved quality of life, particularly in populations with a high rate of consanguinity.

BACKGROUND: Delivery of supplemental oxygen is the initial vital management of hypoxemic acute lower respiratory infection (HALRI). Oxygen delivery systems include low-flow and high-flow devices. In high-flow devices such as the Venturi mask, a constant mixture of oxygen is delivered. As a result, increased rate of breathing does not affect the concentration of oxygen delivered. In this study, we compared the efficacy of oxygen masks and Venturi masks in the management of hypoxemia in pediatric patients. METHODS: A total of 65 children, aged 3-36 months, diagnosed with HALRI, were enrolled. Patients were allocated into groups, via simple alternate randomization, to receive oxygen through an oxygen mask or through a Venturi mask. Respiratory rate, heart rate, retraction, blood gas parameters, oxygen saturation, length of hospitalization, and oxygenation were recorded before and after oxygen treatment. RESULTS: After 24 h of treatment, respiratory rate was significantly lower among patients in the Venturi mask group compared with the oxygen mask group. Duration of supplemental oxygen and length of hospitalization were significantly lower in the Venturi mask group compared with the oxygen mask group. CONCLUSION: In both groups, there was marked improvement in all measured parameters following introduction of supplemental oxygen. Oxygen was delivered more efficiently, however, by high-flow systems. The Venturi mask may decrease the total duration of oxygen usage time as well as the length of hospitalization among young children with HALRI through rapid symptom resolution.

Paracetamol is the most commonly used analgesic after cleft palate repair. It has rarely caused acute hepatic failure at therapeutic or supratherapeutic doses. Only one case of therapeutic paracetamol toxicity after cleft palate repair had been reported previously. Here, we present a similar patient who developed acute liver failure and hepatic encephalopathy after an uncomplicated cleft palate surgery. Lack of large prospective trials in young children due to ethical concerns increases the value of the case reports of acetaminophen toxicity at therapeutic doses. The dosing recommendations of paracetamol may need to be reconsidered after cleft palate surgery.

BACKGROUND: The aim of the study was to investigate the frequency of malnutrition in hospitalized children and compare national growth standards with World Health Organization (WHO) standards. METHODS: After obtaining height, weight, and mid-upper arm circumference values for 250 children aged 1 month to 5 years, nutrition status was assessed separately according to Neyzi and WHO standards. Weight-for-age z score (WAZ), weight-for-height z score (WHZ), height-for-age z score (HAZ), and mid-upper arm circumference z score (MUACz) were calculated based on age. Patients with WHZ < -2 were considered to have acute malnutrition, while those with HAZ < -2 were considered to have chronic malnutrition per WHO's definition. RESULTS: According to the WHO and Neyzi standards, the z scores were as follows: WAZ (-0.53 ± 1.54/-0.61 ± 1.52), HAZ (-0.42 ± 1.61/-0.45 ± 1.38), WHZ (-0.33 ± 1.26/none), MUACz (-0.58 ± 1.31/none). The difference between WAZ scores for the two standards was highly significant (P = 0.0001), whereas the difference between HAZ scores didn't reach statistical significance (P = 0.052). In our study when evaluated according to WHO standards, the prevalence of acute and chronic malnutrition was 9.6% and 13.6%, respectively. The prevalence of chronic malnutrition in those aged <2 years was higher than in the 2-5 years age group (16.8% and 4.5%, respectively; P = 0.012). CONCLUSION: There were highly significant differences in the assessment of malnutrition between the WHO and national Neyzi according to WAZ standards, contradicting the claim that WHO curves can be universally applicable. The high rates of acute and chronic malnutrition in our study indicate that malnutrition remains a significant nutrition problem in our country.
RESUMEN
OBJECTIVE: Over the past decades, the incidence of acute pancreatitis is increasing, but the progression of acute recurrent pancreatitis and chronic pancreatitis is still not well documented in children. The aim of this multicenter study is to delineate the changes that occur in a certain time period in the course of childhood pancreatitis. MATERIALS AND METHODS: The data of consecutive patients hospitalized with acute pancreatitis between 2010 and 2017 in 4 different pediatric gastroenterology units were reviewed. The clini- cal characteristics of the disease were defined. RESULTS: A total of 165 patients (55.2% female) were included. Over the years, the rate of acute pancreatitis admissions increased while the duration of hospitalization decreased (P < .05). Nearly two-thirds of the patients with acute pancreatitis resolved spontaneously, 30.9% and 4.3% of the cases developed acute recurrent pancreatitis and chronic pancreatitis, respectively. Furthermore, 27.4% patients with acute recurrent pancreatitis progressed to chronic pancre- atitis, and eventually, 12.7% of cases developed chronic pancreatitis within 3-4 years. Local complications developed in 13.3% of the patients with pancreatitis in this cohort. CONCLUSION: The result of this study confirmed the increased incidence of acute pancreatitis in recent years. Conversely, the length of hospital stay decreased over the years. Patients with pancreaticobiliary abnormalities or genetic risk factors had a higher rate of progression to acute recurrent pancreatitis or chronic pancreatitis. Therefore, genetic testing and radiological imaging should be considered early in the follow-up of patients with acute pancreatitis having risk factors for progression to acute recurrent pancreatitis/chronic pancreatitis.
RESUMEN
Nonalcoholic fatty liver disease (NAFLD) is a multisystem disease and is significantly associated with obesity, insulin resistance, type 2 diabetes mellitus, metabolic syndrome, and cardiovascular disease. NAFLD has become the most prevalent chronic liver disease in Western countries, and the proportion of NAFLD-related cirrhosis among patients on liver transplantation waiting lists has increased. In light of the accumulated data about NAFLD, and to provide a common approach with multi-disciplines dealing with the subject, it has become necessary to create new guidance for diagnosing and treating NAFLD. This guidance was prepared following an interdisciplinary study under the leadership of the Turkish Association for the Study of the Liver (TASL), Fatty Liver Special Interest Group. This new TASL Guidance is a practical application guide on NAFLD and was prepared to standardize the clinical approach to diagnosing and treating NAFLD patients. This guidance reflects many advances in the field of NAFLD. The proposals in this guidance are meant to aid decision-making in clinical practice. The guidance is primarily intended for gastroenterology, endocrinology, metabolism diseases, cardiology, internal medicine, pediatric specialists, and family medicine specialists.
RESUMEN
OBJECTIVES: The aim of this study was to evaluate the features of asymptomatic siblings of index celiac patients who were diagnosed with celiac disease (CD) at the initial screening. METHODS: We reviewed hospital records of 210 children with CD. The characteristics of sibling celiacs (n=24) were compared with index celiacs (n=186). RESULTS: At diagnosis, sibling celiacs were older than index celiacs (mean (SD) 10.4 (2.7) vs 8.2 (4.3) years; P=0.02). There were no significant differences between sibling and index celiacs in terms of serum anti-tTG IgA titer (≥10xULN, 83.3% vs 85%), and most of the patients had moderate/severe villous atrophy in both groups. The rates of iron deficiency anemia, folic acid deficiency, wasting and stunting were comparable between sibling and index celiac patients. CONCLUSIONS: Siblings with CD were older than index children with CD at diagnosis, and their characteristics were similar to symptomatic index children with CD, despite not having any complaints.

Fasciola hepatica is a zoonotic liver trematode that usually causes infection in cattle and sheep, and is transmitted to humans by consuming water and aquatic plants contaminated with metacercaria. The detection of Fasciola eggs in stools, serological evaluation and radiological evaluation are essential for diagnosis. Triclabendazole is the first-line therapy for fascioliasis. However, as triclabendazole is not an easily accessible drug in countries such as Turkey, it reveals a quest for alternative therapies. In this report, we present a 10-year-old boy with fascioliasis successfully treated with a course of metronidazole 1.5 g/day for 3 weeks in 2020. During the follow-up, eosinophilia and radiological findings completely recovered. Here we report a case of pediatric fascioliasis that was cured with metronidazole successfully.
RESUMEN
BACKGROUND: Currently, there is no comprehensive and multidisciplinary recommendation study covering all aspects of pediatric dysphagia (PD). This study aimed to generate PD management recommendations with methods that can be used in clinical practice to fill this gap in our country and in the world, from the perspective of experienced multidisciplinary experts. METHODS: This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-round modified Delphi survey via e-mail. First, ten open-ended questions were created, and then detailed recommendations including management, diagnosis, treatment, and follow-up were created with the answers from these questions. Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation) and divergent consensus (not recommended). RESULTS: In the 1st Delphi round, a questionnaire of 414 items was prepared based on the experts' responses to ten open-ended questions. In the 2nd Delphi round, 59.2% of these items were accepted as pre-recommendation. In the 3rd Delphi round, 62.6% of 246 items were accepted for inclusion in the proposals. The final version recommendations consisted of 154 items. CONCLUSIONS: This study includes comprehensive and detailed answers for every problem that could be posed in clinical practice for the management of PD, and recommendations are for all pediatric patients with both oropharyngeal and esophageal dysphagia.

BACKGROUND: Perianal disease is reported more widely in pediatric Crohn patients than in the past, and has been stated as an independent modifier of the disease behavior. In this study, we aimed to analyze the clinical characteristics and outcomes of fistulising perianal Crohn's disease (fpCD) in the pediatric age group. METHODS: A total number of 149 children with an established diagnosis of inflammatory bowel disease who have been diagnosed before 18 years of age and followed in our tertiary center were revised. Clinical, endoscopic, laboratory, and radiologic data of 50 patients with CD, who had at least 18 months follow-up data, were compiled. RESULTS: Of 50 patients, 26 (52%) were diagnosed as fpCD (38% at onset). More than half of the patients without any notable external orifices around the perianal area were diagnosed as fpCD by an magnetic resonance imaging (MRI). Pediatric fpCD patients had a higher disease activity score and platelet count, lower serum albumin level, and a higher rate of granuloma in the biopsy samples, compared with non-fistulising patients. A considerably high rate of surgical interventions (i.e., seton placement 46% and abscess drainage 15%) was performed in combination with infliximab. CONCLUSION: Fistulising perianal Crohn's disease seems to be more common than previously reported in the pediatric age group. A severe course of the disease might serve as a warning for the development of fpCD. A careful physical examination and use of perianal MRI with a high index of suspicion may increase the likelihood of fistula detection, hence may change the treatment strategy.

BACKGROUND: The aim of the study was to evaluate familial Mediterranean fever (FMF) mutation analysis in pediatric patients with inflammatory bowel disease (IBD). The relation between MEFV mutations and chronic inflammatory diseases has been reported previously. METHODS: Children with IBD (334 ulcerative colitis (UC), 224 Crohn's disease (CD), 39 indeterminate colitis (IC)) were tested for FMF mutations in this multicenter study. The distribution of mutations according to disease type, histopathological findings, and disease activity indexes was determined. RESULTS: A total of 597 children (mean age: 10.8 ± 4.6 years, M/F: 1.05) with IBD were included in the study. In this study, 41.9% of the patients had FMF mutations. E148Q was the most common mutation in UC and CD, and M694V in IC (30.5%, 34.5%, 47.1%, respectively). There was a significant difference in terms of endoscopic and histopathological findings according to mutation types (homozygous/ heterozygous) in patients with UC (P < .05). There was a statistically significant difference between colonoscopy findings in patients with or without mutations (P = .031, P = .045, respectively). The patients with UC who had mutations had lower Pediatric Ulcerative Colitis Activity Index (PUCAI) scores than the patients without mutations (P = .007). CONCLUSION: Although FMF mutations are unrelated to CD patients, but observed in UC patients with low PUCAI scores, it was established that mutations do not have a high impact on inflammatory response and clinical outcome of the disease.

In this case report, we present the bone scintigraphic findings of a 9-year-old boy with Gaucher disease who has a history of fractures to evaluate the extent of his osseous lesions. Gaucher disease is a genetic deficiency of lysosomal enzyme glucocerebrosidase, which results in the accumulation of glucocerebroside in the macrophages in the reticuloendothelial cells of the spleen, liver, and bone marrow. Most patients with type 1 Gaucher disease present a clinical or radiographic evidence of infiltrative bone disease. Lipid-filled macrophages called Gaucher cells infiltrate the bone marrow, leading to medullary expansion, diffuse osteoporosis, ischemic necrosis, and fractures.

Autoimmune pancreatitis has been described as a pancreatic manifestation of immunoglobulin G4-related disease, which is characterized by typical histopathologic, radiologic, and clinical features. Immunoglobulin G4-related disease is usually accompanied by elevated serum immunoglobulin G4 level, and can involve multiple organ/systems. Immunoglobulin G4-related disease has rarely been reported in pediatric population. There are few reports of inflammatory bowel disease in association with immunoglobulin G4-related disease. We describe a 7-year-old girl who presented with pancreatitis and concurrent sclerosing cholangitis, and developed bloody diarrhea during follow-up. An endoscopic examination revealed inflammatory bowel disease, and later lacrimal gland involvement was also recognized. She was diagnosed as having immunoglobulin G4-related disease, and her clinical signs and symptoms improved dramatically after steroid treatment. Hence, awareness of the clinical picture is important and early diagnosis can prevent fibrosis and organ damage.
