The present study aimed to evaluate the predictive values of D-dimer in patients with HE.Materials and methods: Patients with chronic liver failure (CLF) and HE were enrolled.

IBP was recorded during primary PTBD. The parameters of interest were age, gender, etiology of EHBO, baseline and post-PTBD liver function tests, duration for resolution of jaundice (decrease in total serum bilirubin ≥30% of baseline or <2 mg/dL), cholangitis, bile cultures, and serum albumin levels. The level of EHBO was divided into three types: Type 1 - secondary biliary confluence involved; Type 2 - primary biliary confluence involved; Type 3 - mid and distal common bile duct obstruction.Results: IBP was measured in 102 patients, and finally, 87 patients, including 52 (59.77%) females, were analyzed. The mean age of the patients was 56.1±11.6 years. The most common etiology of EHBO was carcinoma of the gallbladder in 44 (50.6%) patients. The mean IBP was 18.41±3.91 mmHg. IBP was significantly higher in Type 3 EHBO compared to Type 1 and 2 (p=0.012). A significant correlation was seen between IBP and baseline total serum bilirubin (p<0.01). There was a negative correlation between IBP and baseline serum albumin (p=0.017).

Consequently, the disease term has recently changed to Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). Turkiye is one of the leading countries with high incidences of diseases such as diabetes, obesity, metabolic syndrome, and fatty liver. This study aims to identify the metabolic parameters and MASLD potential of NAFLD in Turkiye. All NAFLD studies conducted in Turkiye were systematically searched using the keywords \"fatty liver disease\" AND \" Turkiye \" on PubMed, Scopus, and Web of Science databases. A total of 2653 articles were scanned, and 120 studies were eligible for meta-analysis. The metabolic parameters were meta-analyzed from a broad perspective. According to the meta-analysis results, there were significant increases in waist circumferences (mean difference: 10.90, p<0.00001), HOMA-IR (mean difference: 2.13, p<0.00001), aspartate aminotransferase (AST) (mean difference: 17.82, p<0.00001), systolic blood pressure (SBP) (mean difference: 5.86, p<0.00001), and C-reactive protein (CRP) levels (mean difference: 0.95, p<0.00001). These parameters are representative biochemical findings of disturbed glucose metabolism, lipid profile, blood pressure, and acute phase response mechanisms. Furthermore, the analysis of all related parameters commonly found among the articles confirmed these metabolic dysfunctions. NAFLD is a metabolic disease that encompasses multiple pathways related to glucose and lipid metabolism, vascular function, inflammation, and acute phase responses. Additionally, our results suggest that Turkish NAFLD patients identified in previous studies mostly have MASLD. This is the first meta-analysis study indicating changes in metabolism-related parameters with a cumulative meta-analysis of all Turkish NAFLD studies.","PeriodicalId":29722,"journal":{"name":"Hepatology Forum","volume":"5 3","pages":"126-138"},"PeriodicalIF":1.2,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11237240/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141617275","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}
