A real-life pediatric experience of Crohn's disease exclusion diet at disease onset and in refractory patients.

OBJECTIVES: We aimed to appraise the real-life efficacy of Crohn's disease exclusion diet (CDED) coupled with partial enteral nutrition (PEN) in inducing clinical and biochemical remission at disease onset and in patients with loss of response to biologics and immunomodulators. METHODS: We retrospectively gathered data of patients aged less than 18 years of age with a diagnosis of Crohn's disease (CD), who received CDED coupled with PEN at a tertiary level pediatric inflammatory bowel disease center. RESULTS: Sixty-six patients were identified. Forty (60.6%) started CDED plus PEN at disease onset and 26 (39.4%) received CDED with PEN as add-on therapy. Forty-six (69.7%) patients achieved clinical remission (weighted Pediatric Crohn's Disease Activity Index < 12.5) at the end of Phase 1, 44 (66.7%) normalized c-reactive protein levels (<0.5 mg/dL) and 18 (27.2%) patients normalized calprotectin levels (<150 microg/g). Nine of 19 (47.3%) of patients with clinically severe disease (defined by Physician Global Assessment) achieved clinical remission at the end of Phase I. Patients with extraintestinal manifestations had statistically lower clinical response rates to the dietary regimen (p = 0.018). Among patients who received CDED + PEN as add-on treatment, a previous successful course of Exclusive Enteral Nutrition was associated with statistically higher clinical remission rates at Week 8 (p = 0.026). Clinical response at Week 4 was an independent predictor of clinical remission and fecal calprotectin normalization at Week 8 (p = 0.002). CONCLUSION: CDED with PEN confirmed its efficacy in a real-life setting, proving to be effective also in refractory patients and those with severe disease. Early clinical response predicts clinical remission at the end of Phase 1.

Mucosal and Histologic Healing in Children With Inflammatory Bowel Disease Treated With Antitumor Necrosis Factor-Alpha.

OBJECTIVES: Mucosal healing (MH) and histological healing (HH) have been recently proposed as a novel treatment target for inflammatory bowel disease (IBD). The aim of the present study was to evaluate real-life achievement of such outcomes in a cohort of pediatric patients with IBD treated with anti-TNF-alpha (ATA) agents. METHODS: A retrospective analysis was performed on patients affected by IBD who received ATA and were followed up at two referral centers. Incidence and cumulative rates for MH and HH for each group were calculated. RESULTS: Of 170 (105 Crohn's disease [CD] and 65 ulcerative colitis [UC]) patients, 78 with CD and 56 with UC underwent endoscopic re-assessment during the study period. MH was achieved by 32 CD (41%) and 30 UC (53.6%) patients; 26 CD (33.3%) and 22 UC (39.3%) patients achieved HH. MH incidence rate was 19.1/1000 and 47/1000 person-months, whereas HH incidence rate was 15.5/1000 and 34.7/1000 person-months for CD and UC, respectively. Remission at the end of induction was associated with higher MH and HH rates (HR: 2.43, P = 0.049 and HR: 2.94, P = 0.046, respectively) in CD. In UC, adalimumab was associated with lower MH and HH rates (HR: 0.16, P = 0.004 and HR: 0.07, P = 0.003). CONCLUSIONS: We reported a real-life experience arising from a large cohort of pediatric IBD who received ATA scheduled treatment. Less than half of patients with CD and only a little >50% of UC patients achieved MH. Microscopical inflammation was observed in 18.8% CD and 26.7% UC patients who achieved MH. Overall, MH and HH rates appear lower compared to previously published data.

Bowel Ultrasound Scan Predicts Corticosteroid Failure in Children With Acute Severe Colitis.

BACKGROUND AND OBJECTIVE: Acute severe colitis (ASC) is a potentially life-threatening event. Optimal timing for second-line treatment in children is mainly based on the clinical score Pediatric Ulcerative Colitis Activity Index. The aim of our study was to evaluate the potential role of bowel ultrasound scan (BUS) in predicting the need of second-line therapy in ASC. METHODS: Patients younger than 18 years admitted to a single tertiary referral center with ASC were included. We retrospectively reviewed medical records collecting clinical and BUS data. Colonic wall thickness (CWT), loss of colonic wall stratification (CWS), presence of hyperechoic lymph nodes, and colonic wall flow evaluated at power Doppler were assessed at BUS performed within the third day of hospitalization. RESULTS: Sixty-nine ASC episodes from 52 different patients were identified. CWT showed significantly higher values in patients who required second-line therapy (5.14 vs 3.69 mm; P < 0.001). Loss of CWS was present in 17 of 36 (47.2%) of steroid-resistant ASC versus only 1 of 33 of those responding to intravenous corticosteroids (P < 0.001, sensitivity = 47%, specificity = 97%). Using a receiver operating characteristic curve, a cut-off of 3.4 mm was individuated for CWT to predict steroid treatment failure, showing a sensitivity of 92% and a specificity of 52%. The multivariable binary logistic regression analysis identified thickened colonic wall (CWT >3.4 mm) and loss of CWS as independent predictors of steroid resistance. CONCLUSIONS: BUS is a noninvasive, easily accessible, and cost-effective resource that may identify at an early stage first-line therapy failure in pediatric ASC.

Characterization of fortuitously discovered focal liver lesions: additional information provided by shearwave elastography.

OBJECTIVES: To prospectively assess the stiffness of incidentally discovered focal liver lesions (FLL) with no history of chronic liver disease or extrahepatic cancer using shearwave elastography (SWE). METHODS: Between June 2011 and May 2012, all FLL fortuitously discovered on ultrasound examination were prospectively included. For each lesion, stiffness was measured (kPa). Characterization of the lesion relied on magnetic resonance imaging (MRI) and/or contrast-enhanced ultrasound, or biopsy. Tumour stiffness was analysed using ANOVA and non-parametric Mann-Whitney tests. RESULTS: 105 lesions were successfully evaluated in 73 patients (61 women, 84%) with a mean age of 44.8 (range: 20‒75). The mean stiffness was 33.3 ± 12.7 kPa for the 60 focal nodular hyperplasia (FNH), 19.7 ± 9.8 k Pa for the 17 hepatocellular adenomas (HCA), 17.1 ± 7 kPa for the 20 haemangiomas, 11.3 ± 4.3 kPa for the five focal fatty sparing, 34.1 ± 7.3 kPa for the two cholangiocarcinomas, and 19.6 kPa for one hepatocellular carcinoma (p < 0.0001). There was no difference between the benign and the malignant groups (p = 0.64). FNHs were significantly stiffer than HCAs (p < 0.0001). Telangiectatic/inflammatory HCAs were significantly stiffer than the steatotic HCAs (p = 0.014). The area under the ROC curve (AUROC) for differentiating FNH from other lesions was 0.86 ± 0.04. CONCLUSION: SWE may provide additional information for the characterization of FFL, and may help in differentiating FNH from HCAs, and in subtyping HCAs. KEY POINTS: • SWE might be helpful for the characterization of solid focal liver lesions • SWE cannot differentiate benign from malignant liver lesions • FNHs are significantly stiffer than other benign lesions • Telangiectatic/inflammatory HCA are significantly stiffer than steatotic ones.

Histological healing as a predictor of sustained clinical remission in paediatric ulcerative colitis.

BACKGROUND: The study aimed to assess the longitudinal impact of endoscopic healing (EH) and histological healing (HH) in a cohort of paediatric patients affected by ulcerative colitis (UC). METHODS: This was a retrospective single-centre longitudinal study. 86 children with UC who underwent endoscopic re-assessment while in clinical and biochemical remission were included. Partial EH was defined as a Mayo Endoscopic Subscore (MES) of 1 and complete EH was defined as a MES of 0. HH was defined as the absence of active inflammation in all biopsies. The cumulative incidence of clinical relapse was evaluated during follow-up. RESULTS: At the second endoscopic re-evaluation, 59 (68.6%) patients achieved EH (MES ≤1). Of these patients, 39 (66%) achieved complete EH. 20 of the 39 patients who achieved complete EH attained complete HH. Patients who achieved partial and complete EH showed higher recurrence-free survival rates compared to those who did not (p < 0.01 and p < 0.01, respectively). Amongst patients with complete EH, those who achieved complete HH had lower recurrence rates when compared to patients who still showed microscopic inflammation (p = 0.049). CONCLUSION: Achievement of EH and HH is associated with fewer disease relapses, with patients achieving HH showing longer relapse-free survival rates.

Major Abdominal Surgery for Pediatric Crohn's Disease in the Anti-TNF Era: 10-Year Analysis of Data From the IBD Registry of Italian Society of Pediatric Gastroenterology, Hepatology, and Nutrition.

BACKGROUND: The natural history of Crohn's disease (CD) can result in complications requiring surgery. Pediatric data are scarce about major abdominal surgery. The IBD Registry from the Italian Society of Pediatric Gastroenterology, Hepatology, and Nutrition has been active since 2008 and collects data from major pediatric IBD centers in Italy. The aim of the present report was to explore the prevalence of major abdominal surgery among children affected by CD in an era when antitumor necrosis factor (anti-TNF-α) agents were already used so that we might appraise the incidence of surgical-related complications and identify the factors associated with postoperative disease recurrence. METHODS: We retrospectively analyzed data from patients enrolled in the registry from January 2009 to December 2018. Patients with monogenic IBD and patients undergoing surgery for perianal disease were excluded. RESULTS: In total, 135 of 1245 patients were identified. We report the prevalence of major abdominal surgery of 10.8%. Pediatric surgeons performed the procedure in 54.1% of cases, and a laparoscopic approach was used in 47.4% of surgical procedures. Seventeen patients (12.6%) experienced a total of 21 early postoperative complications, none of which was severe. A laparoscopic approach was the only factor negatively associated with the occurrence of postoperative complications (odds ratio, 0.22; 95% confidence interval, 0.06-0.8; P = .02). Fifty-four (40%) patients experienced postoperative endoscopic recurrence, and 33 (24.4%) of them experienced postoperative clinical recurrence. The postoperative treatment with anti-TNF-α drugs was significantly associated with a reduced risk of endoscopic recurrence (odds ratio, 0.19; 95% confidence interval, 0.05-0.79; P = .02). CONCLUSION: In our cohort, the overall prevalence of major abdominal surgery was low, as well as the rate of surgical-related complications. Postoperative anti-TNF-α therapy seems be protective against endoscopic recurrence.

Data from the IBD SIGENP registry show that the prevalence of major abdominal surgery is 10.8%, with a relatively low occurrence of short-term postoperative complications. The administration of anti-TNF-α drugs after surgery seems to effectively prevent postoperative endoscopic recurrence of disease.

Diagnosis and management of anemia in pediatric inflammatory bowel diseases: Clinical practice guidelines on behalf of the SIGENP IBD Working group.

Anemia is one of the most frequent extra-intestinal manifestations of inflammatory bowel disease. Insidious onset, variability of symptoms and lack of standardized screening practices may increase the risk of underestimating its burden in children with IBD. Despite its relevance and peculiarity in everyday clinical practice, this topic is only dealt with in a few documents specifically for the pediatric field. The aim of the current guidelines is therefore to provide pediatric gastroenterologists with a practical update to support the clinical and therapeutic management of children with IBD and anemia. A panel of 19 pediatric gastroenterologists and 1 pediatric hematologist with experience in the field of pediatric IBD was agreed by IBD Working group of the Italian Society of Gastroenterology, Hepatology and Nutrition (SIGENP) to produce the present article outlining practical clinical approaches to the pediatric patient with IBD and anemia. The levels of evidence and recommendations have been defined for each part of the statement according to the GRADE system.

Foreign body ingestion in children: Definition of a nomogram to predict surgical or endoscopic intervention.

BACKGROUND AND AIMS: Foreign body ingestion (FBI) in children requires early identification to prevent adverse outcomes and may necessitate endoscopic or surgical intervention. This study aims to develop a nomogram that identifies children who require urgent surgical or endoscopic intervention by using the patient's medical history and clinical parameters collected at admission. METHODS: This study is a retrospective review (01/2015-12/2020) of a multicenter case series of children admitted for FBI. Data from 5864 records from 24 hospitals in Italy were analyzed. Logistic regression models were used to establish the probability of requiring surgical or endoscopic intervention based on patient history and clinical characteristics. The nomogram representing the results from the multivariable model was reported to examine the propensity for surgery/endoscopy. RESULTS: The study identified a significant association between intervention and various factors, including type of foreign body (blunt: reference category, disk battery (odds ratio OR:4.89), food bolus (OR:1.88), magnets (OR:2.61), sharp-pointed (OR:1.65), unknown (OR:1.02)), pre-existing diseases or conditions (OR 3.42), drooling (OR 10.91), dysphagia (OR 5.58), vomiting (OR 3.30), retrosternal pain (OR 5.59), abdominal pain (OR 1.58), hematemesis (OR 2.82), food refusal/poor feeding (OR 2.99), and unexplained crying (OR 2.01). The multivariable regression model showed good calibration and discrimination ability, with an area under the ROC curve of 0.77. CONCLUSIONS: This study developed the first nomogram to predict the probability of the need for surgical or endoscopic intervention in children with FBI, based on the information collected at admission. The nomogram will aid clinicians in identifying children who require early intervention to prevent adverse outcomes.

Vertebral rotation in adolescent idiopathic scoliosis calculated by radiograph and back surface analysis-based methods: correlation between the Raimondi method and rasterstereography.

PURPOSE: The aim of the present research is to evaluate the relationship between an X-ray-based method (i.e. the Raimondi method) and rasterstereography in the evaluation of vertebral rotation (VR) in a sample of adolescent idiopathic scoliosis (AIS) patients. METHODS: A total of 25 patients (9 males; mean age 14 ± 3 years; mean height 160.7 ± 11.9 cm; mean weight 52.4 ± 10.7 kg) were considered for the present analysis. The mean Cobb angle was 30° ± 9°. The evaluation of VR on radiographs was made using the Raimondi method regolo (Marrapese Editore--Demi S.r.1., Rome). Rasterstereography was performed by means of Formetric 4D(®) (Diers International GmbH, Schlangenbad, Germany). Correlations between rasterstereographic and radiographic measurement of VR were calculated, both for the whole sample and for thoracic and lumbar spinal segments considered separately, as well as for subgroups of patients with a Cobb angle <30° and ≥ 30° using Spearman's correlation coefficient by rank (r (s)). RESULTS: When applied to the entire spine, measurement of VR by means of the two methods highlighted a significant correlation in the whole group (r = 0.52; p < 0.0001), as well as in the <30° Cobb (r = 0.47; p = 0.0001) and ≥ 30° Cobb (r = 0.42; p < 0.0001) subgroups. A significant correlation was found also when lumbar and thoracic VR were considered as separated groups (r = 0.30, p = 0.024 and r = 0.47, p = 0.002, respectively). CONCLUSIONS: Rasterstereographic evaluation of VR shows a good correlation with the Raimondi method, thereby confirming the possibility to use this non-invasive method for deformity assessment in AIS patients.

A new evaluation system for early and successful conservative treatment for acute ischial tuberosity avulsion.

In this report we analyse a case of ischiatic tuberosity avulsion. A 15-year-old patient who came to our first aid department two days after a football match accident was treated conservatively and examined at month 1-4, 6 and 12. In order to examine patient condition, a new index was formulated: the inability score index (ISI), which is based on hip range of motion and scales for rest, walking, running pain and compared to other parameters such as oedema area, fragment diastasis evaluated by X-ray and CT accordingly. ISI defines the inability as severe, moderate and mild. It guides the rehabilitative program in the right way. In this case, the patient was able to run softly after 35 days and to go back to the full agonist activity after 4 months. At the end of treatment the patient referred to the complete pain remission, full range of motion recovery and a good fracture consolidation. After 1 year we discuss about therapeutic strategies used and results obtained.

A journey towards pediatric gastrointestinal endoscopy and its training: a narrative review.

Background and aims: Gastrointestinal (GI) endoscopy in pediatric setting has unique features and, therefore, requires an approach that is tailored to pediatric practice. There is still heterogeneity between training programs worldwide in terms of duration, number of procedures and assessment during and at the end of the training process. Methods: We conducted a narrative review aiming to describe and summarize the existing literature on the various training methods for pediatric GI endoscopy to highlight the significance of specific pediatric endoscopy training. Results: Simulation-based tools have been implemented in several training programs, providing a safer learning environment for trainees, especially in their earlier stages of training. Assessment of competence is gradually shifting from the sole evaluation of procedural numbers towards the development of more reliable and valid tools that can accurately measure technical competence. Despite such seismic shift, there is still a need for a standardized and comprehensive pediatric-oriented endoscopy curriculum that incorporates acquisition of procedural skills education and is built on the current competency-based model of training. All the above must sink their roots in trainees and to ensure that the endoscopists of tomorrow are capable of delivering high quality of care for children undergoing endoscopy. Conclusion: It is crucial to parallelly focus on the way trainers teach trainees. In this context, the implementation of "train the trainers" courses has improved important quality meters in GI endoscopy. Future research should put the focus on the potential subsequent favorable benefits of these changes on child health.

Gene expression profiling in white blood cells reveals new insights into the molecular mechanisms of thalidomide in children with inflammatory bowel disease.

Thalidomide has emerged as an effective immunomodulator in the treatment of pediatric patients with inflammatory bowel disease (IBD) refractory to standard therapies. Cereblon (CRBN), a component of E3 protein ligase complex that mediates ubiquitination and proteasomal degradation of target proteins, has been identified as the primary target of thalidomide. CRBN plays a crucial role in thalidomide teratogenicity, however it is unclear whether it is also involved in the therapeutic effects in IBD patients. This study aimed at identifying the molecular mechanisms underpinning thalidomide action in pediatric IBD. In this study, ten IBD pediatric patients responsive to thalidomide were prospectively enrolled. RNA-sequencing (RNA-seq) analysis and functional enrichment analysis were carried out on peripheral blood mononuclear cells (PBMC) obtained before and after twelve weeks of treatment with thalidomide. RNA-seq analysis revealed 378 differentially expressed genes before and after treatment with thalidomide. The most deregulated pathways were cytosolic calcium ion concentration, cAMP-mediated signaling, eicosanoid signaling and inhibition of matrix metalloproteinases. Neuronal signaling mechanisms such as CREB signaling in neurons and axonal guidance signaling also emerged. Connectivity Map analysis revealed that thalidomide gene expression changes were similar to those exposed to MLN4924, an inhibitor of NEDD8 activating enzyme, suggesting that thalidomide exerts its immunomodulatory effects by acting on the ubiquitin-proteasome pathway. In vitro experiments on cell lines confirmed the effect of thalidomide on candidate altered pathways observed in patients. These results represent a unique resource for enhanced understanding of thalidomide mechanism in pediatric patients with IBD, providing novel potential targets associated with drug response.

Changing Dietary Habits: The Impact of Urbanization and Rising Socio-Economic Status in Families from Burkina Faso in Sub-Saharan Africa.

(1) Background: Sub-Saharan Africa is experiencing the fastest urbanization worldwide. People in rural areas still have a traditional and rural lifestyle, whereas the Westernization of diet and lifestyle is already evident in urban areas. This study describes dietary habits of families in Burkina Faso living at different levels of urbanization. (2) Methods: Data on lifestyle, socio-economic conditions, health status and anthropometry were collected from 30 families living in rural villages, a small town and the capital city. A food frequency questionnaire and a 24 h recall diary were used to estimate dietary habits and macronutrients intake. (3) Results: The urban cohort showed a more diversified diet, with a higher intake of animal protein and, especially in children, a higher consumption of simple sugars. Fiber intake was significantly higher in the rural and semi-urbanized cohorts. As expected, overweight and obesity gradually increased with the level of urbanization. In semi-urbanized and urban families, we observed coexistence of under- and over-nutrition, whereas in rural families, a portion of children were wasted and stunted, and adults were underweight. (4) Conclusions: These three cohorts represent a model of the effect on diet of rural-to-urban migration. Rural diet and traditional habits are replaced by a Western-oriented diet when families move to urbanized areas. This dietary transition and increased socio-economic status in newly developing urban areas have a major impact on disease epidemiology, resembling the past evolution in Western countries.

Anti-Tumor Necrosis Factor-Alpha Withdrawal in Children With Inflammatory Bowel Disease in Endoscopic and Histologic Remission.

BACKGROUND: The aim of the present study was to investigate outcomes of anti-TNF-alpha (ATA) withdrawal in selected pediatric patients with inflammatory bowel disease who achieved clinical remission and mucosal and histological healing (MH and HH). METHODS: A retrospective analysis was performed on children and adolescents affected by Crohn disease (CD) and ulcerative colitis (UC) who were followed up at 2 tertiary referral centers from 2008 through 2018. The main outcome measure was clinical relapse rates after ATA withdrawal. RESULTS: One hundred seventy patients received scheduled ATA treatment; 78 patients with CD and 56 patients with UC underwent endoscopic reassessment. We found that MH was achieved by 32 patients with CD (41%) and 30 patients with UC (53.6%); 26 patients with CD (33.3%) and 22 patients with UC (39.3%) achieved HH. The ATA treatment was suspended in 45 patients, 24 affected by CD and 21 by UC, who all achieved concurrently complete MH (Simplified Endoscopic Score for CD, 0; Mayo score, 0, respectively) and HH. All the patients who suspended ATA shifted to an immunomodulatory agent or mesalazine. In contrast, 17 patients, 8 with CD and 9 with UC, continued ATA because of growth needs, the persistence of slight endoscopic lesions, and/or microscopic inflammation. Thirteen out of 24 patients with CD who suspended ATA experienced disease relapse after a median follow-up time of 29 months, whereas no recurrence was observed among the 9 patients with CD who continued treatment (P = 0.05). Among the patients with UC, there were no significant differences in relapse-free survival among those who discontinued ATA and those who did not suspend treatment (P = 0.718). CONCLUSIONS: Despite the application of rigid selection criteria, ATA cessation remains inadvisable in CD. In contrast, in UC, the concurrent achievement of MH and HH may represent promising selection criteria to identify patients in whom treatment withdrawal is feasible.

Epidemiological trends of pediatric IBD in Italy: A 10-year analysis of the Italian society of pediatric gastroenterology, hepatology and nutrition registry.

INTRODUCTION: The present study aimed at evaluating Italian epidemiological trends of pediatric inflammatory bowel diseases (IBD) over the period 2009-2018. MATERIALS AND METHODS: Data from 1969 patients enrolled in the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition Registry, by 49 pediatric IBD centers throughout the country, were analyzed, comparing three different time intervals (2009-2012, 2013-2015, 2016-2018). RESULTS: The number of new IBD diagnoses ranged from 175 to 219 per year, evenly distributed over the examined period of time. From 2009 to 2018, the minimal incidence ranged from 1.59 to 2.04 /105 inhabitants aged < 18 years, with an overall slight predominance of ulcerative colitis (UC) over Crohn's disease (CD) (ratio: 1.1). Mean diagnostic delay was 6.8 months for CD and 4.1 months for UC, with a significant reduction for CD when comparing the three-time intervals (p =0.008). The most frequent disease locations according to the Paris classification were ileocolonic for CD (41.3%) and pancolitis for UC (54.6%). CONCLUSIONS: The minimal incidence rate in Italy seems to have stabilized over the last two decades, even if it has increased when compared to previous reports. UC is still slightly more prevalent than CD in our country. Diagnostic delay significantly decreased for CD, reflecting an improved diagnostic capacity.

Impact of COVID-19 pandemic on pediatric endoscopy: A multicenter study on behalf of the SIGENP Endoscopy Working Group.

BACKGROUND: Aim of the present report was to investigate the repercussions of COVID-19 pandemic on the procedural volumes and on the main indications of pediatric digestive endoscopy in Italy. METHODS: An online survey was distributed at the beginning of December 2020 to Italian digestive endoscopy centers. Data were collected comparing two selected time intervals: the first from 1st of February 2019 to 30th June 2019 and the second from 1st February 2020 to 30th June 2020. RESULTS: Responses to the survey came from 24 pediatric endoscopy Units. Globally, a reduction of 37.2% was observed between 2019 and 2020 periods with a significant decrease in median number of procedures (111 vs 57, p < 0.001). Both the median number of procedures performed for new diagnoses and those for follow-up purposes significantly decreased in 2020 (63 vs 36, p < 0.001 and 42 vs 21, p< 0.001, respectively). We reported a drastic reduction of procedures performed for suspected Celiac Disease and Functional Gastrointestinal Disorders (55.1% and 58.0%, respectively). Diagnostic endoscopies for suspected IBD decreased of 15.5%, whereas procedures for Mucosal Healing (MH) assessment reduced of 48.3%. CONCLUSIONS: Our study provides real-world data outlining the meaningful impact of COVID-19 on pediatric endoscopy practice in Italy.

Impact of COVID-19 pandemic on the management of paediatric inflammatory bowel disease: An Italian multicentre study on behalf of the SIGENP IBD Group.

BACKGROUND: IBD management has been significantly affected during the COVID-19 lockdown with potential clinical issues. AIMS: The aim of this study was to analyse the impact of COVID-19 pandemic on the Italian paediatric IBD cohort. METHODS: This was a multicentre, retrospective, cohort investigation including 21 different Italian IBD referral centres. An electronic data collection was performed among the participating centres including: clinical characteristics of IBD patients, number of COVID-19 cases and clinical outcomes, disease management during the lockdown and the previous 9 weeks. RESULTS: 2291 children affected by IBD were enrolled. We experienced a significant reduction of the hospital admissions [604/2291 (26.3%) vs 1281/2291 (55.9%); p < 0.001]. More specifically, we observed a reduction of hospitalizations for new diagnosis (from n = 44 to n = 27) and endoscopic re-evaluations (from n = 46 to n = 8). Hospitalization for relapses and surgical procedures remained substantially unchanged. Biologic infusions did not significantly vary [393/2291 (17.1%) vs 368/2291 (16%); p = 0.3]. Telemedicine services for children with IBD were activated in 52.3% of the centres. In 42/2291(1.8%) children immunosuppressive therapies were adapted due to the concurrent COVID-19 pandemic. CONCLUSION: Due to the several limitations of the lockdown, cares for children with IBD have been kept to minimal standards, giving priorities to the urgencies and to biologics' infusions and implementing telemedicine services.

Management of paediatric IBD after the peak of COVID-19 pandemic in Italy: A position paper on behalf of the SIGENP IBD working group.

Coronavirus Disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2, spreading in Italy during the first months of 2020, abruptly changed the way of practicing medicine in this country. As a consequence of the lockdown, the diagnostic and therapeutic management of paediatric chronic conditions, such as inflammatory bowel disease (IBD) has been affected. During the peak of COVID-19 pandemic, elective visits, endoscopies and infusions have been postponed, with potential clinical and psychological impact on disease course and a high likelihood of increasing waiting lists. While slowly moving back towards normality, clinicians need to recognize the best ways to care for patients with IBD, carefully avoiding risk factors for new potential epidemic outbreaks. In this uncertain scenario until the development and spread of COVID-19 vaccine, it is necessary to continue to operate with caution. Hereby we provide useful indications for a safer and gradual restarting of routine clinical activities after COVID-19 peak in Italy.
