Although recent clinical practice guidelines (CPGs) advocate for less frequent and selective use of antibiotics, colonoscopies, admissions, and operations, rates of admissions and elective operations for diverticulitis have paradoxically increased over time.

The incidence of metabolic dysfunction-associated steatohepatitis (MASH) and MASLD is rapidly increasing due to the ongoing global epidemic of type 2 diabetes mellitus and obesity. Hepatitis B and C have declined in incidence due to advances in prevention and treatment, yet the overall burden of hepatocellular carcinoma (HCC) continues to rise, largely driven by the growing prevalence of MASLD/MASH. MASLD/MASH is now the fastest-growing etiology of HCC in the USA, France and the UK, with an estimated annual incidence of HCC ranging from 0.5% to 2.6% in patients with MASH cirrhosis. The incidence of HCC among patients with non-cirrhotic MASLD/MASH is lower, approximately 0.1% to 1.3%. There are no screening guidelines currently for HCC in non-cirrhotic MASLD/MASH patients. Our study highlights the dire need to develop HCC predictive strategies and algorithm in this non-cirrhotic population and to move away from a cirrhotic-centered approach but rather use risk-based models. We have identified predictors of development of HCC in this patient population that can be used to develop risk-based HCC screening guidelines and models in a non-cirrhotic population with MASLD/MASH.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Nationwide Inpatient Sample (NIS) database from 2016 to 2019 was used in this analysis.

The mean age was 53.75 years; 52% were female. Older age (P &lt; 0.0001), female gender (adjusted odds ratio (AOR) = 1.303, P &lt; 0.001), and Asian race (AOR = 1.135, P = 0.01) were associated with increased HCC risk. Anemia, leukopenia, hyponatremia, and hypoalbuminemia were independent predictors (all P &lt; 0.001). Benign liver lesions such as focal nodular hyperplasia (AOR = 1.269) and hemangiomas (1.475), as well as infections like cholangitis (3.093) and liver abscess (2.073), were linked to higher risk.

We aimed to evaluate the relationship between statin use and CRC risk in patients with IBD.</p><p><strong>Methods: </strong>A comprehensive review of the literature was conducted on PubMed, Web of Science, and EMBASE to evaluate the association between statin use and the development of CRC in patients with IBD. After deduplication, there were 324 studies screened, and those reporting odds ratios (ORs) or hazard ratios (HRs) for CRC risk in IBD patients using statins were included. The primary endpoints included the development of CRC (OR) and time to CRC (HR). A meta-analysis utilizing fixed or random-effects models, heterogeneity tests, and a funnel plot was performed in R (version 4.3.0) with alpha of 0.05.</p><p><strong>Results: </strong>This meta-analysis included seven studies involving 59,596 patients: three for OR (11,116 patients) and four for HR (48,480 patients). The pooled OR was 0.22 (95% confidence interval (CI): 0.01 - 7.81), suggesting 78% lower odds of CRC in statin users, though not statistically significant (P = 0.21), with potential publication bias. The pooled HR was 0.77 (95% CI: 0.63 - 0.94), indicating a significant 23% reduction in CRC hazard for statin users (P < 0.05), with low publication bias.</p><p><strong>Conclusion: </strong>Our meta-analysis showed that statin use is associated with a reduced risk of CRC in IBD, significant in HR-based but not in OR-based analysis. Large randomized controlled trials are needed to clarify the duration of statin use and their chemopreventive effects, independent of factors such as targeted therapy for chronic mucosal inflammation.</p>","PeriodicalId":12461,"journal":{"name":"Gastroenterology Research","volume":"18 3","pages":"108-118"},"PeriodicalIF":1.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12151120/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144274634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
