RESUMO
OBJECTIVES: The severe course of inflammatory bowel diseases (IBDs) refractory to advanced therapies in children results in the search for new therapeutic methods. The aim of this study was to evaluate the efficacy and safety of dual therapy with biologics in a cohort of children with IBD. METHODS: Retrospective analysis of data from 29 children with a diagnosis of IBD, 19 with ulcerative colitis (66%), 10 with Crohn's disease (CD) (34%) qualified for dual biological therapy (DBT). The median age of patients was five (interquartile range [IQR], 1-15) years at diagnosis of IBD and 14 (IQR, 3-17) years at eligibility for dual therapy. Thirteen (45%) patients were treated with vedolizumab/adalimumab (VDZ + ADA), 13 (45%) with ustekinumab/adalimumab (UST + ADA), three (10%) with infliximab/vedolizumab (IFX + VDZ). RESULTS: Clinical remission was achieved in 13 (45%; seven UC and six CD) and 12 (41%; seven UC and five CD) Pediatric Weighted Crohn's Disease Activity Index (wPCDAI)/Pediatric Ulcerative Colitis Activity Index (PUCAI) patients after 4 and 12 months at the initiation of dual therapy. Clinical response based on wPCDAI/PUCAI was reported in 16 (55%; nine UC and seven CD) and 12 (41% seven UC and five CD) children after 4 and 12 months of follow-up, respectively. The median fecal calprotectin decreased significantly from 1240 µg/g (53-10,100) to 160 µg/g (5-2500; p = 0.004) between baseline and Month 4 and from 749 at baseline (57-10,100) to 17 (5-3110; p = 0.12) over 12 months. Moreover, 34% (six UC and four CD) of patients achieved endoscopic remission. CONCLUSIONS: DBT seems to be an effective alternative therapeutic option for patients with moderate and severe IBD.

BACKGROUND & AIMS: Wilson's disease (WD) is an autosomal recessive disorder associated with disease-causing alterations across the ATP7B gene, with highly variable symptoms and age of onset. We aimed to assess whether the clinical variability of WD relates to modifier genes. METHODS: A total of 248 WD patients were included, of whom 148 were diagnosed after age of 17. Human exome libraries were constructed using AmpliSeq technology and sequenced using the IonProton platform. RESULTS: ATP7B p.His1069Gln mutation was present in 215 patients, with 112 homozygotes and 103 heterozygotes. Three other mutations: p.Gln1351Ter, p.Trp779Ter and c.3402delC were identified in >10 patients. Among patients, 117 had a homozygous mutation, 101 were compound heterozygotes, 27 had one heterozygous mutation, and 3 other patients had no identifiable pathogenic variant of ATP7B. Sixteen mutations were novel, found as part of a compound mutation or as a sole, homozygous mutation. For disease phenotype prediction, age at diagnosis was a deciding factor, while frameshift allelic variants of ATP7B and being male increased the odds of developing a neurological phenotype. Rare allelic variants in ESD and INO80 increased and decreased chances for the neurological phenotype, respectively, while rare variants in APOE and MBD6 decreased the chances of WD early manifestation. Compound mutations contributed to earlier age of onset. CONCLUSIONS: In a Polish population, genetic screening for WD may help genotype for four variants (p.His1069Gln, p.Gln1351Ter, p.Trp779Ter and c.3402delC), with direct sequencing of all ATP7B amplicons as a second diagnostic step. We also identified some allelic variants that may modify a WD phenotype.

OBJECTIVES: The aim of the study was to analyze the clinical presentations, diagnosis, and treatment of patients ages ≤5 years with early onset Wilson disease (WD). METHODS: Data from 143 pediatric patients with WD treated at our center between January 1996 and November 2015 were retrospectively analyzed. RESULTS: A review of the 143 pediatric patients with WD identified 21 (10 girls, 11 boys) with first symptoms or abnormal liver function test results at age ≤5 years. The diagnosis of WD was confirmed in 8 patients younger than 5 years. At baseline the mean serum alanine aminotransferase level was 222 U/L and the mean serum aspartate aminotransferase level was 130 U/L. The mean serum ceruloplasmin concentration in 16 tested patients was <20 mg/dL. Of the 15 patients who underwent urinary copper excretion testing, 8 had levels between 40 and 100 µg/day, with only 4 having levels >100 µg/day. Liver copper quantification was >250 µg/g dry weight in 16 patients. The most common mutation was p.H1069Q, with compound heterozygosity in 5 patients and homozygosity in 9. Sixteen patients were treated with zinc salts and 5 with D-penicillamine. Both treatments were effective, with no serious side effects observed after 3 to 24 months. CONCLUSIONS: WD can present as early as 2 years of age. Because biochemical tests may be less sensitive in very young children, diagnoses may require a combination of tests. If molecular tests are inconclusive, liver copper content should be measured.

BACKGROUND: The appropriate time to initiate enteral nutrition after the placement of a percutaneous endoscopic gastrostomy (PEG) tube has been an area of limited research. There are no sufficient randomised prospective controlled trials in the paediatric population comparing the safety and tolerance of early feeding (3 h) after PEG placement. In order to reduce the period of fasting, inadequate nutritional support, and hospitalisation time, we decided to devise this study. METHODS/DESIGN: This study is a multicentre, randomised, open-label trial designed to evaluate the tolerance and safety of early enteral nutrition after PEG placement in children. Patients are randomised to receive the first feeding bolus with a polymeric diet (1 kcal/ml) via a feeding tube 3 h after the PEG placement (group I - early enteral feeding) or 8 h after the procedure (group II - late enteral feeding). The key objective of the study is to compare the tolerance and safety of the early- and late-feeding modes after PEG placement in children. The primary endpoint is the number of patients who will achieve full feed (total fluid and caloric requirements) within 48 h of the first feeding bolus. The secondary endpoints are: the number of early and late complications, the duration of hospitalisation after PEG placement, gastric residuals (ml) total in the period up to 48 h since the first feeding bolus. DISCUSSION: To our knowledge this is the first study in paediatric patients to evaluate the tolerance and safety of early enteral nutrition after PEG placement. The goal is to establish an optimum standard procedure in the group of paediatric patients qualified for the PEG insertion procedure in Poland. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT02777541 , registration date 05/18/2016.

THE AIM OF THE STUDY: Assessment of clinical and endoscopic efficacy of induction therapy with infliximab in children with ulcerative colitis. MATERIAL AND METHODS: This is a retrospective analysis of medical records of pediatric patients with moderate to severe UC who had received at least one infusion of infliximab in Polish pediatric academic clinical centers from 2003 to 2013. The primary endpoint was clinical remission rate at week 10, (PUCAI score <10 points) while the secondary endpoints were: clinical response rate (>19-points decrease in PUCAI), mucosal response rate (defined as an improvement of the Baron score), and mucosal healing rate (Baron score 0 or 1). RESULTS: 44 patients, at mean age of 14±3.9 years, were included into the study. 38 (86%) patients completed induction therapy regimen with infliximab and were finally included into the analysis. Clinical response and remission rates at week 10 there were 36% and 25% respectively. There was significant drop of PUCAI (58.31±15.5 vs. 24.23±23.83) and Baron score (2.63±0.49 vs. 1.44±0.99) at this time point. Mucosal response and mucosal healing rate were 57% and 48% respectively. Infliximab failure defined as non-clinical and non-mucosal response at week 10, occurred in 16 patients. Infliximab-associated adverse events occurred in 3 patients, with all severe hypersensitivity reactions to infliximab. CONCLUSIONS: Infliximab induction therapy was safe and effective in Polish moderate to severe UC pediatric patients with 50% rate of mucosal improvement. However, clinical response rate was lower than previously reported.

OBJECTIVE: Many protocols of bowel preparation are available for use in children; however, none of them is commonly accepted. The aim of the study was to evaluate the efficacy and acceptability of high-volume polyethylene glycol (PEG) versus low-volume PEG combined with bisacodyl (BPEG) versus sennosides for colonoscopy preparation in children. METHODS: Participants ages 10 to 18 years were randomly assigned to receive either PEG 60 or PEG 30 mL kg⻹ day⻹ plus oral bisacodyl 10 to 15 mg/day or sennosides 2 mg kg⻹ day⻹ for 2 days. A blinded assessment of bowel cleansing was made by the endoscopist according to the Aronchick and Ottawa scales. Patient acceptability was evaluated with the visual-analog scale. Analysis was done on an available case analysis basis. RESULTS: Of 240 patients enrolled in the study 234 patients were available for analysis of the efficacy of colon cleansing. There were no significant differences found among the 3 groups for the proportions of participants with excellent/good (PEG: 35/79, BPEG: 26/79, sennosides 25/76) and poor/inadequate (PEG: 20/79, BPEG: 28/79, sennosides 28/76) bowel preparation evaluated with the Aronchick scale and for the mean Ottawa total score (PEG: 5.47â±â3.63, BPEG: 6.22â±â3.3, sennosides: 6.18â±â3.53). Acceptability of bowel cleansing protocol was similar in all of the groups (Pâ=â0.8). CONCLUSIONS: All 3 cleansing methods showed similar efficacy and tolerability; however, none of them was satisfactory.

BACKGROUND: Inflammatory bowel diseases in children are characterized by a wide variety of symptoms and often a severe clinical course. In the treatment, we aimed to induce and maintain remission. We focused on assessing the efficacy and safety of the concomitant use of two biologic therapies including: anti-TNF (infliximab, adalimumab) vedolizumab and ustekinumab in a refractory pediatric IBD cohort. METHODS: Fourteen children (nine ulcerative colitis, one ulcerative colitis/IBD-unspecified, four Crohn's disease) with a disease duration of 5.2 (8 months-14 years) years, initiated dual therapy at an age of 11.7 (3-17) years after failure of monotherapy with a biological drug. Five patients (36%) were treated with vedolizumab/adalimumab (VDZ + ADA), five (36%) with ustekinumab/adalimumab (UST + ADA), and three (21%) with infliximab/vedolizumab (IFX + VDZ). One patient (7%) was switched from a combination of vedolizumab and adalimumab to ustekinumab and adalimumab during follow-up. RESULTS: A clinical improvement was obtained in ten children (73%; 5 UC, 1 UC/IBD-unspecified, 4 CD) on the PCDAI/PUCAI scale after 4 months of a second biological drug being added. The median fecal calprotectin decreased from 1610 µg/g (140-10,100) to 586 µg/g (5-3410; p = 0.028) between baseline and 4 months. CONCLUSIONS: Our clinical experience suggests that dual therapy may be an option for pediatric patients with moderate and severe courses of IBD with limited therapeutic options.
RESUMO
(1) Background: The CDED + PEN (partial enteral nutrition) is a promising method of nutritional treatment in active Crohn's disease (CD). An increase in fecal calprotectin (FCP) levela marker of mucosal inflammationhappens to be the first evidence of Crohn's disease exacerbation that appears ahead of clinical symptoms and usually co-exists with them. In this study, we present our own experience with using the CDED + PEN in the treatment of children with CD and an increased FCP level. (2) Methods: In total, 48 children (male/female: 27/21) aged 4−17 years (median value = 13.43; IQR = 4.00) were treated with CDED + PEN between June 2019 and July 2021. The main inclusion criteria for the study was active CD defined as an FCP level ≥ 250.00 µg/g. Patients with severe clinical manifestation of CD (PCDAI >40.00), as well as ones who started any new concomitant CD treatment later than at least 4 weeks before the start of dietary intervention, were excluded from the analysis. The PCDAI and fecal calprotectin level were assessed at weeks 0 and 12. The primary endpoint was ITT normalization of FCP level, i.e., a result < 250.00 µg/g at week 12. The Wilcoxon Matched Pairs Test was used for statistical analysis. (3) Results: The normalization of the FCP level was obtained in 17 children (35.42%) and an FCP level decrease of at least 50% occurred in 26 patients (54.17%). The reduction in fecal calprotectin level between week 0 and week 12 was statistically significant with a median value of 1045.00 µg/g; IQR = 1188.00, and 363.00 µg/g; IQR = 665.00, respectively (p < 0.05). Among 29 patients who were not in clinical remission at baseline, 16 (55.17%) achieved clinical remission (PCDAI < 10.00) at week 12 and 20 (68.97%) obtained a clinical response defined as at least a 12.50 point drop in PCDAI or remission. In this group, the reduction in PCDAI between baseline and week 12 was statistically significant (median value = 20.00 points; IQR = 7.50 and 5.00 points; IQR = 5.00, respectively (p < 0.05)). All patients with a normal FCP level at week 12 were in clinical remission and 16 (94.13%) of them had a normal CRP (C-reactive protein) value. In 10 children (20.83%) the full course of 12 weeks with CDED + PEN was not completed or the concomitant therapy had been started before week 12 due to the lack of efficacy/intolerance of nutritional treatment. (4) Conclusions: The 12-week course of treatment with the CDED + PEN has a beneficial effect on the fecal calprotectin level in children with active CD. The dietary intervention led to a significant decrease in the FCP level in the studied group and to the normalization of this parameter in every third patient.
RESUMO
BACKGROUND: Infusion reactions (IRs) are the most common adverse events (AEs) of infliximab (IFX) treatment in patients with inflammatory bowel disease (IBD). Prophylactic premedication (PM) with corticosteroids or antihistamines prior to IFX infusions has been used in clinical practice, but its efficacy is not known. The aim of this study was to assess the influence of steroid PM on IR incidence in pediatric patients with IBD receiving IFX. METHODS: We performed a case-control study that included pediatric patients with IBD receiving IFX. Patients were divided into four subgroups according to the agent and PM they received: Remicade (original drug) + PM, and two biosimilars-Reshma +/- PM, and Flixabi-PM. At our site, until 2018, PM with steroids was used as a part of standard IFX infusion (PM+); however, since then, this method has no longer been administered (PM-). IRs were divided into mild/severe reactions. Differences between subgroups were assessed with the appropriate chi-square test. Multivariate logistic regression was used to assess associations between PM and IR incidence, correcting for co-medication usage. RESULTS: There were 105 children (55 PM+, 44 male, mean age 15 years) included in the study who received 1276 infusions. There was no difference between the PM+ and PM- subgroups, either in incidence of IR (18.2% vs. 16.0% of patients, p > 0.05) or in percentage of infusions followed by IR (2.02% vs. 1.02% of infusions, p > 0.5). The OR of developing IR when using PM was 0.34, and the difference in IRs ratio in PM+ and PM- patients was not statistically significant (95% CI, 0.034-1.9). There were 11/18 (61.1%) severe IRs (anaphylactic shock) reported in all patients (both PM+ and PM-). CONCLUSION: At our site, the incidence of IR was low, and PM did not decrease the incidence of IR in pediatric patients with IBD receiving IFX. These results indicate that PM with steroids should not be a standard part of IFX infusion to prevent IR.
RESUMO
OBJECTIVES: The aim of the study was to assess the complication rate and identify whether age, nutritional status, and history of respiratory aspiration prior to percutaneous endoscopic gastrostomy (PEG) are risk factors for post-PEG placement complications in Polish children. In addition, the safety of two enteral feeding methods (3 h vs. 8 h) after PEG insertion in children was compared. METHODS: Children with clinical indications for PEG placement were recruited from six medical centers in Poland to participate in the study. The patients were centrally randomized to receive the first bolus feed via a feeding tube at 3 h (group 1) or 8 h (group 2) after PEG placement. The preprocedural preparation, postoperative care, and resumption of feeding were performed on all of patients in accordance with the study protocol. Patients were followed for 12 mo. RESULTS: Of the 97 randomized patients, 49 were assigned to group 1 and 48 to group 2. Full feed after PEG placement was achieved within 24 to 48 h in most cases (74% vs. 82%). There were no differences between the groups regarding the number of early mild (31.3% vs. 31.3%) and serious (2.1% vs 8.3%) complications or the duration of hospitalization after PEG placement (P > 0.05). The most common serious complication after PEG placement was accidental displacement of PEG. Most reported late complications were mild. The results of the regression analysis indicate no statistically significant effect of age, body mass index standard deviation score, white blood cell count, serum albumin level, and respiratory aspiration in the medical history on the occurrence of mild and severe complications. CONCLUSIONS: The early initiation of post-PEG feeding was not associated with an increase in the number of complications. Most complications after the PEG procedure were mild. Age, serum albumin level, white blood cells, body mass index standard deviation score, and a history of aspiration to the respiratory tract were not confirmed as a risk factor for post-PEG complications in children.

BACKGROUND & AIMS: We assessed the tolerability and safety of implementing early enteral nutrition in children at 3 h after percutaneous endoscopic gastrostomy (PEG) placement to establish an optimum feeding mode in paediatric patients that reduced the fasting period, the inadequate nutritional support interval, and the hospitalisation time. METHODS: Children with clinical indications for PEG placement were recruited from six medical centres in Poland to participate in the study. The patients were centrally randomised to receive the first bolus feed, which comprised a polymeric diet (1 kcal/mL), via a feeding tube at 3 h (group 1) or 8 h (group 2) after PEG placement. The pre-procedural preparation, the post-operative care, and the resumption of feeding were performed on all of the patients in accordance with the study's protocol. The primary endpoint was the number of patients who consumed a full feed, which contained their total fluid and caloric requirements, within 48 h of the first bolus feed. The secondary endpoints were the number of complications and the duration of hospitalisation after PEG placement. RESULTS: Of the 97 randomised patients, 49 were assigned to group 1 and 48 were assigned to group 2. There were no differences between the groups regarding feeding tolerability (81.6% vs. 91.6%), the number of complications (25.5% vs. 37.5%), or the duration of hospitalisation after PEG placement (p > 0.05). Full feed post PEG placement was achieved within 24-48 h in most cases (74% vs. 82%). Most of the complications were mild. Two patients in group 2 due to dislocation of the PEG were qualified for laparotomy (at 6 days post-PEG placement in one case and at 14 days post-PEG placement in the other case). One patient in group 2 died at 7 days post-PEG placement; the death was unrelated to the investigation. CONCLUSIONS: Introducing feeding at 3 h post-PEG placement in children appears to be well tolerated. The early initiation of post-PEG feeding was not associated with an increase in the number of complications and it had no impact on the duration of hospitalisation.

AIM: To verify the impact of induction therapy with infliximab (IFX) on mucosal healing in children with ulcerative colitis (UC). METHODS: The study included all UC pediatric patients treated with IFX at our center over the last 10 years. The data were collected from patients' medical charts and analyzed retrospectively. A total of 16 patients with UC underwent colonoscopy with sample collection before and after three IFX injections. Pediatric Ulcerative Colitis Activity Index (PUCAI) was used to assess the clinical condition; endoscopic features were classified according to the Baron scale; and histological changes were evaluated according to the protocol of The British Society of Gastroenterology and Geboes Index. Clinical response was defined as a ≥ 20-point reduction in PUCAI index, and clinical remission as PUCAI index < 10 points. Endoscopic mucosal remission was defined as completely normal (score 0) on the Baron scale. Histological remission was defined as grade 0 in the Geboes Index. To assess correlation between variables, Spearman's rank correlation coefficient was used. RESULTS: Clinical remission (PUCAI < 10) at week 8 was achieved in 68.75% of investigated subjects. Endoscopic mucosal remission at week 8 (Baron 0) was observed in 12.5% of patients. Histological remission (Geboes 0) after induction therapy with IFX was noticed in 18.75% cases. A general histological improvement, expressed by normal surface and crypt architecture, number of crypts, and lamina propria cellularity, was observed in six (37.5%) patients; there was no improvement in nine (56.25%) individuals, and worsening was observed in one (3.75%) case. Changes were not related to UC location. A reduction of inflammatory process was observed in 10 (62.5%) patients; there were no changes in four (25%) individuals, and the inflammation became more severe in two (12.5 %) cases. Simultaneous clinical, endoscopic and histological improvement of parameters assessing disease activity at week 8 was noticed in six (37.5%) patients. 55.5% of investigated patients with normal mucosa seen on endoscopy showed no inflammation on histology. A Baron score of 2 and 3 showed a good correlation with histology results (78.2% of patients with a Geboes Index ≥ 3). CONCLUSION: IFX has a positive histological effect in more than one-third of UC patients. IFX reduces intestinal inflammation and improves clinical condition.

In recent years, a novel biologic therapy with monoclonal antibodies against tumor necrosis factor-alpha has revolutionized the treatment of Crohn's disease. Infliximab, the first biologic agent, has been demonstrated to considerably improve both clinical and endoscopic outcomes. In view of the growing popularity of infliximab in the management of Crohn's disease, we review the profile of the agent in the treatment of this disease in a pediatric setting.
RESUMO
Gastroesophageal reflux is one of the most common reasons for referrals to paediatricians or paediatric gastroenterologists. Gastric acid-buffering agents, mucosal surface barriers and gastric anti-secretory agents are the main groups of medications currently used for treating gastroesophageal reflux disease (GERD) in children. Recently, the use of proton pump inhibitors (PPIs) for the treatment of GERD in children has increased considerably. Their effectiveness in healing erosive oesophagitis in paediatric subjects and in improving GERD symptoms has been established in many studies. However, the effectiveness in other clinical conditions and the long-term safety of PPIs for paediatric GERD have not been fully established yet and thus are still under debate. Therefore, the aim of this article is to provide a comparative review of the efficacy, safety and tolerability of PPIs in paediatric GERD. The available data suggest that short-term use of PPIs is well tolerated. Adverse events tend to be of a mild-to-moderate nature, with headache being the most frequently reported treatment-related adverse event. However, further well-designed trials and observational studies are still needed to clarify the efficacy and safety of PPIs in the paediatric population, especially in infants under the age of 12 months.

AIM: To investigate the side effects of a zinc sulphate therapy in a cohort of Polish pediatric patients with Wilson's disease. METHODS: We retrospectively analyzed a cohort of 53 pediatric patients with Wilson's disease treated at the Children's Memorial Health Institute in Warsaw, Poland between the years 1996 and 2011 with zinc sulphate. Patients were diagnosed with Wilson's disease according to the scoring system of Ferenci, with 49 cases confirmed by mutation analysis. Data about the dosage scheme of zinc sulphate, side effects and efficacy and toxicity of the treatment were collected and recorded in the patient's medical chart at each visit to the hospital. RESULTS: Mean age of diagnosis for the entire cohort was 10 years (range, 2.5-17 years). Duration of treatment with zinc sulfate was 83.3 wk (range, 8-344 wk). Side effects, all of gastrointestinal origin, were observed in 21 patients (40%--9 males and 12 females), irrespective of the duration of therapy. Thirteen out of 21 patients were over the age of 10 years. The most common ATP7B mutation was p.H1069Q. Esophagogastroduodenoscopy, performed in 7 patients (33.3%) suffering from persistent and severe abdominal pain, revealed gastrointestinal ulcerations or erosions with negative Helicobacter pylori tests in all subjects investigated. The above mentioned 7 patients were treated with proton pump inhibitors. Three of those experienced resolution of symptoms, whereas proton-pump inhibitors failed to alleviate symptoms of the remaining four children and conversion of therapy to D-penicillamine was needed. CONCLUSION: Zinc sulphate appears to cause significant gastrointestinal side effects, which children on therapy for Wilson's disease should be closely monitored for.
