While PERTs have been on the market for several decades, newer publications on their clinical efficacy and safety raised the need for a comprehensive review of the literature. We aimed to identify the available evidence on the clinical efficacy and safety of treatments for EPI to understand the current treatment landscape and unmet need in patients with EPI.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A systematic literature review (SLR) was conducted in Embase, Medline, and Evidence-Based Medicine databases from 2010 to 2022; conference proceedings from 2020 to 2022 were also searched. Articles were screened independently by two reviewers at abstract and full-text stage against predefined eligibility criteria.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;We identified 26 journal publications and two conference abstracts, reporting on 22 randomized control trials, four observational studies, and two single-arm interventional studies. The most reported treatment was pancrelipase, specifically Creon® (n = 12). Fourteen studies reported coefficient of fat absorption (CFA) results. Across studies, patients experienced a considerable increase in CFA post-initiation of treatment regardless of intervention or timepoint. Mean change in CFA ranged from 7.5% in patients with CP who received placebo to 36% in patients with CP treated with Creon®. Ten studies reported coefficient of nitrogen absorption (CNA). Where reported, pancrelipase (including Creon®) increased CNA levels in EPI patients compared to placebo. Only one study compared PERT brands head-to-head: no significant differences were reported in the CNA-72 h values (Creon® 82.0% [SE: 1.2] vs. Zenpep® 80.9% [SE: 1.2]). Loss of body weight and low body mass index (BMI) are important features of EPI. Overall, treatment with PERT increased BMI and body weight, or limited their decline, with increases ranging from 0.1 to 6.1 kg.

The bioinformatics analysis was applied to reveal the differential expression of KIF4A in CC and its correlation with genes related to stemness or glycolysis.

This study investigates adherence to national and international guidelines by analyzing reporting practices among 21 endoscopists in 7 German centers, with a focus on polyp reporting.</p><p><strong>Methods: </strong>We identified and assessed German, European, American, and World Health Organization-provided statements to identify key elements in colonoscopy reporting. Board-certified gastroenterologists rated the relevance of each element and estimated their reporting frequency. Adherence to the identified report elements was evaluated for 874 polyps from 351 colonoscopy reports ranging from March 2021 to March 2022.</p><p><strong>Results: </strong>We identified numerous recommendations for colonoscopy reporting. We categorized the reasoning behind those recommendations into clinical relevance, justification, and quality control and research. Although all elements were considered relevant by the surveyed gastroenterologists, discrepancies were observed in the evaluated reports. Particularly diminutive polyps or attributes which are rarely abnormal (e.g., surface integrity) respectively rarely performed (e.g., injection) were sparsely documented. Furthermore, the white light morphology of polyps was inconsistently documented using either the Paris classification or free text. In summary, the analysis of 874 reported polyps revealed heterogeneous adherence to the recommendations, with reporting frequencies ranging from 3% to 89%.</p><p><strong>Conclusion: </strong>The inhomogeneous report practices may result from implicit reporting practices and recommendations with varying clinical relevance. Future recommendations should clearly differentiate between clinical relevance and research and quality control or explanatory purposes. Additionally, the role of computer-assisted documentation should be further evaluated to increase report frequencies of non-pathological findings and diminutive polyps.</p>","PeriodicalId":11315,"journal":{"name":"Digestion","volume":" ","pages":"224-231"},"PeriodicalIF":3.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11151964/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140119120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
