Pediatric Gastroenterology and Hepatology in Italy before and after the COVID-19: Lessons learned and management changes by SIGENP.

Around the world, the 2019 Coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has raised serious public health problems and major medical challenges. The Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP) published several papers on the impact of COVID-19 on the current management, diagnosis, and treatment of acute and chronic gastrointestinal, hepatic, immune-mediated, and functional disorders. The present article summarizes the most relevant SIGENP reports and consensus during and after the peak of the COVID-19 outbreak, including the diagnosis and treatment of inflammatory bowel disease (IBD), indications and timing of digestive endoscopy, and insights into the novel hepatitis.

Health-Related Quality of Life in Pediatric Inflammatory Bowel Disease During COVID-19 Pandemic: A Prospective Study.

OBJECTIVES: The aims of our study were to evaluate health-related quality of life (HRQoL) in children affected by inflammatory bowel disease (IBD) during the first wave of Coronavirus disease 2019 (COVID-19) pandemic and after 12 months. METHODS: This was a single-center, prospective, observational study conducted between April 2020 and April 2021. Children from 10 to 18 years with a confirmed diagnosis of IBD were enrolled during the first COVID-19-related national quarantine. The following information was collected at the baseline and after 12 months: IBD subtype, location and phenotype, disease activity, current and previous therapies. Patients were asked to complete the PROMIS Anxiety and IMPACT III questionnaires. RESULTS: One hundred and eighteen patients were enrolled, of whom 54 (46%) were affected by Crohn disease (CD) and 64 (54%) with ulcerative colitis (UC; median age: 15.5 years, range 10.3-18; M/F: 68/50). Median HRQoL was significantly decreased after 12 months compared with the beginning of COVID-19-related quarantine (T1: 76.7 vs T2: 72.8; P < 0.001). At 12 months, a higher number of children were reported to be in active disease when compared with the enrollment [T2: 22/108 (20.4%) vs T1: 12/118 (10%); P = 0.02]. Multivariate analysis showed a significant influence on HRQoL of quarantine period ( P < 0.001), female sex ( P = 0.016), biologic therapy ( P = 0.011), and active disease ( P < 0.001). CONCLUSIONS: A deterioration of HRQoL after 12 months from COVID-19-related quarantine was observed. Additionally, the higher number of children with active disease at 12 months compared with enrollment may suggest detrimental consequences of the reduced disease control, contributing to decreased HRQoL.

Overall Impact of Coronavirus Disease 2019 Outbreak in Children With Functional Abdominal Pain Disorders: Results From the First Pandemic Phase.

OBJECTIVE: We aimed to assess how the first phase of coronavirus disease 2019 (COVID-19) pandemic influenced symptoms in children with functional abdominal pain disorders (FAPDs) and to characterize their quality of life (QoL), anxiety and global health. METHODS: This was a multicenter, observational, international study conducted between April and July 2020 at six different referral centers. Children diagnosed with FAPDs between October 2019 and February 2020 were enrolled and prospectively interviewed at 4 months of follow-up during the first pandemic phase (Quarantine group). Patients were asked to complete PedsQL 4.0 Generic Core Scale and PROMIS Anxiety and Global Health questionnaires. A cohort of children diagnosed with FAPDs between October 2018 and February 2019 was used as a Control group. RESULTS: Three-hundred-fifty-six children were enrolled of whom 180 (mean age at diagnosis: 14 ±â€Š2.8 years) in the Quarantine group and 176 (mean age at diagnosis: 13 ±â€Š2.8 years) in the Control group. At 4 months of follow-up, we observed a significant reduction of children reporting >5 episodes of abdominal pain per month when compared to baseline, in both groups (Quarantine group: 63.9% vs 42.2%, P < 0.001; Control group: 83.5% vs 50%, P < 0.001). The Quarantine group had median QoL values of 84.8 with 16.6% of children showing high anxiety values and 55% having decreased global health score. CONCLUSIONS: We demonstrated symptoms' improvement at 4 months of follow-up in both cohorts. During the first months of the COVID-19 quarantine children with FAPDs showed satisfactory QoL and anxiety scores, suggesting positive effects of school closure and increased parental attention.

Age-Related Differences in the Expression of Most Relevant Mediators of SARS-CoV-2 Infection in Human Respiratory and Gastrointestinal Tract.

Background: Clinical features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection seem to differ in children compared to that in adults. It has been hypothesized that the lower clinical severity in children could be influenced by differential expression of the main host functional receptor to SARS-CoV-2, the angiotensin-converting enzyme 2 (ACE2), but data are still conflicting. To explore the origin of age-dependent clinical features of coronavirus disease 2019 (COVID-19), we comparatively evaluated the expression in children and adult subjects of the most relevant mediators of the SARS-CoV-2 infection: ACE2, angiotensin-converting enzyme 1 (ACE1), transmembrane serine protease-2 (TMPRSS2), and neuropilin-1 (NRP1), at upper respiratory tract and small intestine level. Methods: The expression of ACE2, ACE1, TMPRSS2, and NRP1 in nasal epithelium and in small intestine epithelium was investigated by quantitative real-time PCR analysis. Results: We found no differences in ACE2, ACE1, and TMPRSS2 expression in the nasal epithelium comparing children and adult subjects. In contrast, nasal epithelium NRP1 expression was lower in children compared to that in adults. Intestinal ACE2 expression was higher in children compared to that in adults, whereas intestinal ACE1 expression was higher in adults. Intestinal TMPRSS2 and NRP1 expression was similar comparing children and adult subjects. Conclusions: The lower severity of SARS-CoV-2 infection observed in children may be due to a different expression of nasal NRP1, that promotes the virus interaction with ACE2. However, the common findings of intestinal symptoms in children could be due to a higher expression of ACE2 at this level. The insights from these data will be useful in determining the treatment policies and preventive measures for COVID-19.

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.
