Background: Non-alcoholic fatty liver disease (NAFLD) is a frequent condition in obese patients and regularly progresses to non-alcoholic steatohepatitis (NASH) and subsequent cirrhosis. Histologic evaluation is the gold standard for grading and staging, but invasive biopsies are associated with obvious risks. The aim of this study was to evaluate different non-invasive tools for screening of NAFLD and fibrosis in obese patients.
Methods: In a prospective cohort study liver specimens of 141 patients were taken during bariatric surgery. Serological parameters and clinical data were collected and the following scores calculated: NASH clinical scoring system (NCS), aspartate aminotransferase to platelet ratio index (APRI), FIB-4 as well as NAFLD fibrosis score (NFS). Liver function capacity was measured preoperatively by LiMAx test (enzymatic capacity of cytochrome P450 1A2). Intraoperative liver biopsies were classified using NAFLD activity score (NAS) and steatosis, activity and fibrosis (SAF) score.
Results: APRI was able to differentiate between not NASH and definite NASH with a sensitivity of 74% and specificity of 67% (AUROC 0.76). LiMAx and NCS also showed significant differences between not NASH and definite NASH. No significant differences were found for NFS and Fib-4. APRI had a high sensitivity (83%) and specificity (76%) in distinguishing fibrosis from no fibrosis (AUROC = 0.81). NCS and Fib-4 also revealed high AUROCs (0.85 and 0.67), whereas LiMAx and NFS did not show statistically significant differences between fibrosis stages. Out of the patients with borderline NASH in the histologic NAS score, 48% were classified as NASH by SAF score.
Conclusions: APRI allows screening of NAFLD as well as fibrosis in obese patients. This score is easy to calculate and affordable, while conveniently only using routine clinical parameters. Using the NAS histologic scoring system bears the risk of underdiagnosing NASH in comparison to SAF score.

Background And Aim: Identifying the factors contributing to the progression of metabolic dysfunction-associated steatotic liver disease (MASLD), a lifestyle-related disease, is crucial for preventing future liver-related deaths. This study aimed to epidemiologically investigate factors, including single-nucleotide polymorphisms (SNPs) associated with alanine aminotransferase (ALT) levels >30 U/L and potential risk factors for liver fibrosis, in a general population cohort of patients with MASLD.
Methods: Among 1059 participants in the health checkup project, 228 who were diagnosed with MASLD were analyzed.

In this article, we comment on the article by Qu and Li, focusing specifically on the non-invasive diagnostic approaches for metabolic dysfunction-associated steatotic liver disease (MASLD). MASLD is the most common chronic liver disease in children. Nearly half of pediatric MASLD cases progress to metabolic dysfunction-associated steatohepatitis at diagnosis, often with comorbidities like renal disease, hypertension, type 2 diabetes, and mental health disorders.

Objective: This study aims to explore the relationship between thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TgAb) levels and metabolic dysfunction-associated fatty liver disease (MAFLD) in patients with type 2 diabetes mellitus (T2DM), providing a theoretical basis for MAFLD prevention and treatment.
Methods: From June 2020 to May 2023, 534 T2DM patients were selected from the Endocrinology Department of Xiangyang Hospital affiliated with Wuhan University of Science and Technology. After applying exclusion criteria, 432 subjects were included.

Background: Nonalcoholic fatty liver disease (NAFLD) comprises multiple heterogeneous pathophysiological conditions commonly evaluated by suboptimal liver biopsies. This study aimed to elucidate the role of 13 diverse histological liver scores in assessing NAFLD disease activity using an in silico pharmacometric model-based approach. We further sought to investigate various noninvasive patient characteristics for their ability to reflect all 13 histological scores and the NAFLD activity score (NAS).

Background: Type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD) were often coexistent conditions driven by insulin resistance and systemic inflammation. Effective management strategies that address both metabolic disorders were urgently needed. This study investigates the effect of combining semaglutide, a glucagon-like peptide-1 receptor agonist, with metformin on liver inflammation and pancreatic beta-cell function in patients with T2DM and NAFLD.
