Abstract

What is known and objective: The morbidity of inflammatory bowel disease (IBD) in children has significantly increased in recent years. The diagnosis and treatment of IBD in children are progressing rapidly. Probiotics have been extensively studied in a variety of gastrointestinal diseases. However, the effectiveness of probiotics for IBD is inconsistent. This study summarized the recommendations on using probiotics from high-quality guidelines, and the recommendations may assist clinicians in the treatment of paediatric IBD.

Methods: Guidelines were identified by searching PubMed, EMBASE, three Chinese literature databases and websites of relevant institutions. Guidelines that addressed the treatments of paediatric IBD in Chinese and English were included and evaluated with the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument to assess methodological quality. The levels of recommendation were also evaluated, and finally, the recommendations of probiotics application in IBD were summarized.

Results and discussion: A total of 14 guidelines that met inclusion criteria were identified and evaluated, and 12 of them were evidence-based (EB) guidelines, and the other two guidelines were developed by consensus. The mean percentages for the AGREE II domain scores were as follows: "Scope and purpose" 97.22%, "Clarity of presentation" 93.78%, "Applicability" 55.85%, "Editorial independence" 59.92%, "Stakeholder involvement" 74.34%, and "Rigor of development" 71.58%. Three guidelines received the Grade A-"Strongly recommended," the rest of the guidelines received a B grade-"Recommended with modifications" in the overall assessment.

What is new and conclusion: The overall quality of the guidelines on IBD management in children was high. Conversely, the fundamental recommendations on the application of probiotics in the treatment of IBD varied. For instance, the recommendations of probiotics on Crohn's disease (CD) were not available by any of the analysed guidelines, the recommendations of utilizing probiotics in treating ulcerative colitis (UC) were not uniform as several guidelines considered using VSL#3 or Escherichia coli Nissle 1917 for the treatment.
