Purpose: The purpose of our study was to assess the diagnostic potential of helical CT-enteroclysis (HCTE) and to correlate our findings to endoscopic and surgical results.
Methods: Twenty-eight consecutive patients suffering from histologic proven Crohn disease underwent HCTE and endoscopy within 4 weeks. HCTE findings were read by two observers in consensus and compared with endoscopic and surgical results.
Results: Morphological signs of an acute or recurrent bowel inflammation were found in 25 of 28 (89%) patients. HCTE demonstrated accurately all mural and extramural changes of the inflamed bowel walls. Moreover, in 18 of 25 (72%) patients, HCTE depicted additional pathologic changes such as fistulas, abscesses, and skip lesions, all of which could not be visualized by endoscopy.
Conclusion: HCTE is an accurate technique to detect mural and extramural abnormalities in patients with Crohn disease. HCTE should be considered as a complementary imaging method to endoscopy, and should be the first imaging method especially when Crohn-associated complications are suspected.

The pandemic of coronavirus disease 2019 (COVID-19) had a major impact on the health of people worldwide, including the pediatric inflammatory bowel disease (PIBD) patients. As no study has investigated the susceptibility and disease course of COVID-19 in PIBD patients after the end of zero-COVID policy in China, we conducted a retrospective cross-sectional study in our center. A cross-sectional survey enrolling PIBD patients has been completed by online survey, phone, and face-to-face assessment.

Background: The emergence of tumor necrosis factor inhibitors (anti-TNF) has considerably changed the management of inflammatory bowel disease (IBD) in patients who do not respond to traditional therapies. This study assesses the prevalence of anti-TNF drug levels (DLs) and antibodies (ATAbs) in patients with IBD in Saudi Arabia and explores their associations with IBD type and prior anti-TNF failure.
Methods: This cross-sectional study included patients aged 14-75 years diagnosed with Crohn's disease (CD) or ulcerative colitis (UC), treated with anti-TNF medications at King Fahad Medical City over January 2016 to December 2022.

Background: Data on biosimilar use in pediatric inflammatory bowel diseases (IBD) are scarce compared to the status of studies in adults, resulting in limitations in its treatment. We compared effectiveness and safety of biosimilars versus originators in this population.
Methods: We used data from the French National Health Data System to identify children (less than 18 years old at treatment initiation) initiating treatment with a biosimilar or the originator infliximab or adalimumab for Crohn's disease (CD) or ulcerative colitis (UC), from first biosimilar launch (January 2015 and October 2018, respectively) to 31 December 2022.
