To confirm intestinal GVHD and to rule out differential diagnoses endoscopy is frequently needed. Currently, there are no specific consensus recommendations concerning the best method for endoscopic exploration and medical management of this disease in children, with limited studies available, including a low number of patients. Sigmoidoscopy could be initially proposed under sedation. If sigmoidoscopy is normal or if a general anaesthesia is required, colonoscopy and upper endoscopy should be planned, avoiding duodenal biopsy because of the risk of duodenal haematoma. Regarding therapeutic options, corticosteroids are the first-line treatment for GVHD. Ruxolitinib, a Janus kinase inhibitor, is indicated for children aged 12 years and older with acute or chronic GVHD who have an inadequate response to corticosteroids or other systemic therapies.

Risk of bias were assessed using Risk of Bias Tool (RoB 2) in RevMan (version 5.4, Cochrane Collaboration).

No evidence supported the effectiveness of prebiotics in reducing depression and anxiety in children and adolescents. Four studies presented low risk of bias, while others showed some bias in the randomization process, allocation concealment, selective reporting, and blinding of the outcome assessment.
