Efficacy and Hypoglycaemia Outcomes With Once-Weekly IcoSema Versus Comparators in Individuals With Type 2 Diabetes by Kidney and Liver Function: A Post Hoc Analysis of the COMBINE 1-3 Trials.

AIMS: This post hoc analysis of COMBINE 1-3 assessed efficacy and hypoglycaemia outcomes with IcoSema (once-weekly combination therapy of basal insulin icodec and semaglutide [a glucagon-like peptide-1 analogue]) versus comparators in adults with type 2 diabetes (T2D) by kidney and liver function subgroups. MATERIALS AND METHODS: Treatment outcomes were analysed by trial according to kidney (estimated glomerular filtration rate &#x2265;&#x2009;90; 60-<&#x2009;90; 30-<&#x2009;60; <&#x2009;30&#x2009;mL/min/1.73&#x2009;m2) and liver (total bilirubin &#x2264;&#x2009;21&#x2009;&#x3bc;mol/L or aspartate aminotransferase [AST] &#x2264;&#x2009;31/&#x2264;&#x2009;37 [female/male] U/L; total bilirubin >&#x2009;21&#x2009;&#x3bc;mol/L or AST >&#x2009;31/>&#x2009;37 [female/male] U/L) function subgroups. RESULTS: In COMBINE 1-3, across kidney and liver function subgroups, there were no statistically significant treatment by subgroup interactions for change in glycated haemoglobin (HbA1c) (baseline to week 52), change in body weight (baseline to week 52) or rates of combined clinically significant or severe hypoglycaemia (not assessed by kidney function for COMBINE 2) (all p&#x2009;>&#x2009;0.05). There were statistically significant treatment by kidney function subgroup interactions for the achievement of HbA1c <&#x2009;7.0% without weight gain and without clinically significant or severe hypoglycaemia in COMBINE 3 (p&#x2009;<&#x2009;0.05) but not COMBINE 1 or 2, and statistically significant treatment by liver function subgroup interactions in COMBINE 1 (p&#x2009;<&#x2009;0.05) but not COMBINE 2 or 3. For COMBINE 1 and 3, there were statistically significant treatment by kidney function subgroup interactions for mean weekly total insulin dose, but not statistically significant treatment by liver function subgroup interactions. CONCLUSIONS: Efficacy and hypoglycaemia outcomes with IcoSema versus comparators were generally consistent among adults with T2D with mild to moderate kidney impairment or impaired liver function. TRIAL REGISTRATION: The COMBINE 1-3 trials were sponsored by Novo Nordisk and are registered with ClinicalTrials.gov (NCT05352815; NCT05259033; NCT05013229).

A Dynamic Nomogram to Predict Metabolic Dysfunction-Associated Fatty Liver Disease in Patients with Metabolic Syndrome.

BACKGROUND: Metabolic syndrome (MetS) involves multiple metabolic disorders. This study aimed to identify high-risk populations for metabolic dysfunction-associated fatty liver disease (MAFLD) in patients with MetS and to establish a dynamic predictive nomogram. METHODS: A total of 627 patients with MetS from six regions in Zhejiang Province were enrolled and categorized into MAFLD and non-MAFLD groups, then randomly assigned to training and validation sets at a ratio of 7:3. Independent predictors of MAFLD were identified using least absolute shrinkage and selection operator regression and multivariable logistic regression analyses. These predictors were then used to construct a dynamic nomogram. RESULTS: A total of 627 patients with MetS were included in the final analysis, of whom 77.0% (483/627) were diagnosed with MAFLD. Multivariable logistic regression analysis identified body mass index (BMI), waist circumference (WC), total cholesterol (TC), alanine aminotransferase (ALT), MetS-defined dysglycemia, and education level as independent risk factors for MAFLD. MetS-defined dysglycemia showed the highest odds ratio (OR) for MAFLD development [OR = 1.87, 95% confidence interval (CI): 1.07-3.29]. Although the number of MetS components and the metabolic syndrome score were significantly associated with MAFLD in univariate analysis, they were not independently associated with MAFLD in the multivariate model. A dynamic nomogram for predicting MAFLD risk in patients with MetS was developed and internally validated. The area under the receiver operating characteristic curve was 0.834 (95% CI: 0.787-0.880) in the training set and 0.839 (95% CI: 0.771-0.899) in the validation set, indicating strong predictive performance. Bootstrap internal validation demonstrated good agreement between predicted and observed outcomes in calibration curves. Decision curve analysis further indicated favorable clinical applicability of the nomogram. CONCLUSION: BMI, WC, TC, ALT, MetS-defined dysglycemia, and education level are independent risk factors for MAFLD. A dynamic nomogram for predicting MAFLD risk in patients with MetS was successfully developed and validated.

Efficacy of dapagliflozin on hepatic steatosis and fibrosis in patients with type 2 diabetes mellitus and metabolic dysfunction-associated steatotic liver disease: a pre-specified single-arm analysis from a randomized controlled trial.

AIM: To evaluate the association of dapagliflozin therapy with changes in hepatic steatosis and non-invasive fibrosis surrogate markers in patients with type 2 diabetes mellitus (T2DM) and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) over 12&#xa0;months. METHODS: This is a pre-specified single-arm analysis from a randomised, open-label, parallel-group trial. Of 54 participants randomised to dapagliflozin 10&#xa0;mg daily, 50 (92.6%) completed the 12-month follow-up and were included in the per-protocol analysis. Assessments at baseline, 3, 6, and 12&#xa0;months included transient elastography (CAP and LSM), ultrasonography, and biochemical tests. Primary endpoints were changes in hepatic steatosis (CAP) and non-invasive fibrosis surrogates (LSM). RESULTS: Significant reductions were observed in hepatic steatosis (CAP: 316.7 to 245.7&#xa0;dB/m; mean change&#xa0;-&#xa0;71.02&#xa0;dB/m, 95% CI: -63.4 to&#xa0;-&#xa0;78.6; p&#xa0;<&#xa0;0.001) and in liver stiffness as a non-invasive fibrosis surrogate (LSM: 8.59 to 7.28&#xa0;kPa; mean change&#xa0;-&#xa0;1.31&#xa0;kPa, 95% CI: -0.92 to&#xa0;-&#xa0;1.70; p&#xa0;<&#xa0;0.001). Improvements were also observed in glycaemic control, body weight, lipid profile, liver enzymes, ultrasonographic steatosis grading, and serum fibrosis markers. Genitourinary infections were the most frequently reported adverse events (32%); no serious adverse events were recorded. CONCLUSIONS: Dapagliflozin was associated with significant improvements in hepatic steatosis, non-invasive fibrosis surrogate markers, metabolic parameters, and liver function in T2DM patients with MASLD over 12&#xa0;months. These findings provide region-specific evidence for an Indian population and support further controlled investigation. However, these findings should be interpreted in light of the pre-specified single-arm design of this analysis, the open-label methodology, relatively small sample size, and the absence of liver biopsy confirmation.

Effects of multistrain probiotic supplementation on hepatic function and anthropometric parameters in patients with metabolic dysfunction-associated steatotic liver disease: a double-blind, randomized controlled trial.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly prevalent on a global scale. The gut microbiota is integral to its pathogenesis, prompting extensive research into microbiota modulation as a potential adjunctive therapeutic strategy. AIM: The study aimed to evaluate the effect of multistrain probiotics supplementation on hepatic function in patients with MASLD in a double-blind, randomized, controlled trial. The primary outcomes were changes in Fibrosis-4 index (FIB-4) and fatty liver index (FLI). Secondary outcomes included changes in anthropometric parameters, selected biochemical markers, and other liver-related indices. METHODS: A total of 64 patients with MASLD were randomly assigned to two groups receiving either placebo (C) or a probiotic mixture (PRO) containing the following bacterial strains: 50% Lactococcus lactis Rosell-1058, 25% Lacticaseibacillus casei Rosell-215, 12.5% Lactobacillus helveticus Rosell-52, 12.5% Bifidobacterium bifidum Rosell-71 for 12 wk. RESULTS: Significant group &#xd7; time interactions were observed for FIB-4 (Q = 0.007), with reduction in the PRO group and increase in the C group (-0.05 vs. 0.10; P = 0.002). No significant interaction was found for FLI (Q = 0.942). Significant group &#xd7; time interactions were also observed for aspartate aminotransferase (-2.87 vs. 1.87 U/L; Q = 0.003) and APRI (-0.03 vs. 0.02; Q = 0.001), favoring the PRO group (P < 0.001 for both). No significant changes were observed in anthropometric parameters, glucose levels, or lipid profile. CONCLUSIONS: In patients with MASLD, the 12-wk probiotic supplementation had a modest but statistically significant effect on FIB-4, aspartate aminotransferase, and APRI, with no significant effect on FLI or anthropometric and metabolic parameters. These findings suggest that this probiotic formulation may have potential benefits for liver function in MASLD. However, long-term studies incorporating imaging-based and histological endpoints are required to determine the clinical significance of these findings.

Chinese herbal medicine Xiangsu Hewei Granules in treating non-erosive gastroesophageal reflux disease with liver stomach stagnation heat syndrome: A multicentre, randomized, double-blind, placebo-controlled trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Xiangsu Hewei Granules are an herbal preparation that has shown potential for controlling symptoms of nonerosive gastroesophageal reflux disease (NERD) in preliminary studies. However, high-quality randomized controlled evidence for its use in NERD remains lacking. AIM: To verify the efficacy and safety of Xiangsu Hewei Granules in treating NERD with liver stomach stagnation heat syndrome. MATERIALS AND METHODS: This randomized, double-blind, placebo-controlled, multicentre phase III trial included 480 patients (aged 18-65 years) with confirmed NERD (GerdQ&#x2265;8; negative H. pylori) and traditional Chinese medicine (TCM) liver stomach stagnation heat syndrome. Patients were randomized 3:1 to receive either Xiangsu Hewei Granules or placebo, thrice daily for 8 weeks. The primary outcomes were the effective rate of the response based on visual analog scale (VAS) scores for heartburn and acid regurgitation at week 8. The secondary outcomes included reductions in the TCM syndrome score, etc. RESULTS: 479 participants (mean age 48.5 years, SD10.2; 54.3% female) entered the full analysis set and safety set (360 tests group; 119 control group, 1 participant in the control group withdrawing before medication). At week 8, compared with the control group, the test group demonstrated significantly better effective rate of VAS score response for heartburn(76.39% vs 21.01%, 95% CI 55.38 (45.98, 62.94) %, p&#x202f;<&#x202f;0.01),acid regurgitation (79.72% vs 23.53%, 95% CI56.39 (46.90, 64.12) %, p&#x202f;<&#x202f;0.01), and TCM syndrome score (69.23% vs 30.13%, p&#x202f;<&#x202f;0.01) at week 8. CONCLUSION: In this selected population of NERD patients with liver-stomach stagnation heat syndrome (e.g., negative H. pylori, no pH-impedance phenotype, and low anxiety/depression scores), Xiangsu Hewei Granules demonstrated efficacy and safety in improving heartburn, acid regurgitation, and TCM syndrome scores. However, generalizability to the broader NERD population and its comparative effectiveness against standard proton pump inhibitor therapy require further investigation.

A 7-mm Covered TIPS Reduces&#xa0;Hepatic Encephalopathy Without Increasing Rebleeding in Cirrhotic Patients With Small Liver: A Randomized Study.

BACKGROUND/AIMS: International guidelines recommend initiating transjugular intrahepatic portosystemic shunt (TIPS) placement with an 8-mm stent. However, there is an evident lack of randomized controlled trials evaluating TIPS diameters <&#x2009;8&#x2009;mm in cirrhotic patients with a relatively small liver. The aim of this study was to determine whether 7&#x2009;mm-covered TIPS, compared with 8-mm stents, could achieve comparable shunt function with a lower incidence of hepatic encephalopathy (HE). METHODS: In this multicenter randomized controlled trial, patients with cirrhosis and relatively small liver were randomized 1:1 to receive TIPS with a 7-mm (n&#x2009;=&#x2009;92) or 8-mm (n&#x2009;=&#x2009;92) covered stent to prevent variceal rebleeding. The primary endpoint was the incidence of overt HE after randomization. All-cause rebleeding, orthotopic liver transplantation (OLT)-free survival and a composite of these outcomes, were designated as secondary endpoints. RESULTS: Among the 184 enrolled patients, the predominant etiologies of liver cirrhosis were hepatitis B virus infection (56.0%) and alcohol-related liver disease (20.7%). Over a median follow-up of 26.5&#x2009;months, overt HE occurred in 19 patients (20.7%) in the 7-mm group and 33 patients (35.9%) in the 8-mm group. The 2-year cumulative incidence of overt HE was significantly lower in the 7-mm group than in the 8-mm group (21.4% vs. 37.2%, p&#x2009;=&#x2009;0.02). Stent diameter, post-TIPS portosystemic pressure gradient, pre-covert HE and MELD-Na score were identified as independent risk factors for overt HE. The rates of shunt dysfunction were statistically similar between groups (8.7% vs. 8.7%, p&#x2009;=&#x2009;1.0), as were 2-year rebleeding rates (10.9% vs. 9.8%, p&#x2009;=&#x2009;0.81) and OLT-free survival rates (91.3% vs. 88.0%, p&#x2009;=&#x2009;0.82). CONCLUSIONS: A 7-mm covered TIPS demonstrated comparable shunt function to an 8-mm covered stents, with a significantly lower risk of overt HE. These findings support consideration of 7-mm TIPS stents for preventing variceal rebleeding in cirrhotic patients with a small liver who are undergoing TIPS.

Functional role and regulatory network of miR-22-3p in chicken hepatic lipid metabolism.

Although microRNA-22-3p (miR-22-3p) is abundantly expressed in the avian liver, its epigenetic role in lipid homeostasis remains largely uncharacterized. To elucidate its in vivo function, 14-day-old female Qingyuan Partridge chickens were intravenously injected with lentiviral vectors to establish miR-22-3p overexpression and knockdown models. Phenotypic analysis demonstrated that miR-22-3p knockdown significantly elevated hepatic triglyceride (TG) levels (p&#xa0;<&#xa0;0.05) and drove marked steatosis, whereas its overexpression reduced TG content. Transcriptome sequencing (RNA-Seq) revealed profound metabolic remodeling, identifying 23 core lipid-associated genes (e.g., ELOVL6, FADS2, ACSBG2, and PTGIS) heavily enriched in steroid biosynthesis, fatty acid metabolism, and elongation pathways. In conclusion, miR-22-3p functions as a bidirectional epigenetic rheostat that negatively regulates hepatic lipid deposition by orchestrating a multilayered polygenic network, providing novel molecular targets for mitigating avian metabolic disorders and optimizing production traits in indigenous poultry breeds.

Plasma proteome profiling identifies XPNPEP3 as a novel biomarker associated with metabolic dysfunction-associated steatotic liver disease in patients with type 2 diabetes mellitus.

OBJECTIVE: To identify plasma protein differences between type 2 diabetes mellitus (T2DM) patients with and without metabolic dysfunction-associated steatotic liver disease (MASLD), and to evaluate the diagnostic potential of X-prolyl aminopeptidase 3 (XPNPEP3) for identifying MASLD in T2DM patients. METHODS: Twenty T2DM inpatients were categorized into groups with and without MASLD and their plasma samples&#xa0;were analyzed using data-independent acquisition mass spectrometry, followed by bioinformatics analysis to identify differentially expressed proteins. The cohort was then expanded to 84 patients, and plasma XPNPEP3 levels were validated by enzyme-linked immunosorbent assay. Correlation between XPNPEP3 and clinical indicators were evaluated, and diagnostic performance was determined via receiver operating characteristic (ROC) analysis. Immunohistochemistry was employed to compare hepatic XPNPEP3 expression between the two groups. RESULTS: Proteomic analysis identified 176 differentially expressed proteins, with XPNPEP3 exhibiting the most significant down-regulation by fold change. In the validation cohort, plasma XPNPEP3 was significantly lower in T2DM+MASLD versus T2DM alone. XPNPEP3 levels were negatively correlated with diabetes duration, liver function markers, and triglyceride levels, and was identified as an independent factor inversely associated with MASLD in T2DM.ROC analysis demonstrated strong diagnostic performance for XPNPEP3, further enhanced when combined with BMI and diabetes duration.&#xa0; Immunohistochemistry confirmed reduced hepatic XPNPEP3 expression in T2DM+MASLD patients. CONCLUSIONS: Lower plasma XPNPEP3 is independently associated with MASLD in T2DM patients and demonstrates strong diagnostic potential, positioning XPNPEP3 as a promising biomarker for diagnosing MASLD in T2DM patients and a novel target for non-invasive diagnostic tool development.

Liver Cancer Risk and Incidence Attributable to Human Immunodeficiency Virus: A Meta-Analysis and Population-Attributable Modeling Study of Over 1.2 Million Individuals.

HIV-induced immune suppression and chronic inflammation elevate the risk of cancer progression. We conducted a systematic review and meta-analysis of studies published between January 1, 1984 and October 13, 2023 to assess the association between HIV infection and liver cancer. People living with HIV (PLHIV) had a higher risk (pooled relative risk&#x2009;=&#x2009;3.36, 95% CI: 2.72-4.15). The global PAF for HIV-attributed liver cancer was 1.43% in 2019, with a three-fold increase over the past 30&#x2009;years. The Asia-Pacific region recorded the second highest new cases of HIV-attributed liver cancer in 2019, and the highest age-standardized incidence rate (ASIR) in Eastern and Southern Africa. Particularly, the ASIR of HIV-attributed liver cancer increased rapidly in Eastern Europe and Central Asia, with the highest estimated annual percentage change reaching 22.98%. PLHIV have an increased risk and incidence of liver cancer. In regions with high burden of HIV-attributed liver cancer, it is essential to integrate prevention and effective treatment for HIV, viral hepatitis, alcoholic liver disease, nonalcoholic steatohepatitis, and liver cancer.

Efficacy and safety of human albumin combined with furosemide in acute decompensated heart failure with hepatic dysfunction.

BACKGROUND: Congestion is the most common clinical presentation on admission of patients with acute decompensated heart failure (ADHF). Finding effective ways to alleviate congestion has become a pivotal management step. This study sought to investigate the efficacy and safety of intravenous (IV) albumin use in conjunction with furosemide in patients hospitalized for ADHF with hepatic dysfunction in terms of subjective regression of congestion symptoms and worsening renal function. METHODS: This prospective, open-label, randomized-pragmatic trial recruited 241 patients with hepatic dysfunction hospitalized for ADHF. Patients (78 years, 54% female) were assigned to receive IV albumin with furosemide or IV furosemide alone. The coprimary study endpoints were patients' global assessment of symptoms score, quantified as the area under the curve (AUC) of the score on a visual analog scale, and the change in creatinine levels over 72 hours from admission. RESULTS: The experimental treatment group demonstrated a greater improvement in patients' global assessment of symptoms scores (AUCbaseline-72 h 3,767 vs 3,457 points; P < .001) and a milder increase in creatinine levels (0.07 vs 0.18 mg/dL; P = .045) than the IV furosemide group. The length of stay was 1 day shorter (4 vs 5 days; P < .001) and the incidence of worsening renal function was lower (25% vs 38%; P = .037) in the experimental treatment group. CONCLUSIONS: In this hypothesis generating study, among patients with ADHF and hepatic dysfunction, concomitant use of IV albumin and furosemide for the first 72 hours resulted in a significant improvement in subjective perception symptoms of decongestion and a milder increase in creatinine levels than IV furosemide alone.

Liver transcriptome analysis revealed multiple immune processes and lipid metabolism pathways involved in the defense response of the turbot (Scophthalmus maximus) against Aeromonas salmonicida.

Aeromonas salmonicida is a significant pathogen causing notable economic losses in Scophthalmus maximus aquaculture. This study utilized Illumina sequencing technology to examine the transcriptional response characteristics of S. maximus liver at 24&#xa0;h following A. salmonicida infection. A total of 2363 differentially expressed genes (DEGs) were identified when compared to the negative control group. The immunity-related Toll-like receptor signaling pathway, NOD-like receptor signaling pathway, as well as metabolism-related PPAR signaling pathway and insulin signaling pathway, were notably enriched. Significant differences exist in the expression of key genes within the PPAR pathway, particularly cd36, acsl4a, ppar&#x3b1;a, and plin2, all of which mediate the interaction between lipid metabolism and the immune response. These results offer valuable insights into the immunometabolic regulatory mechanism of S. maximus response to A. salmonicida infection.

The glucagon and GLP-1 receptor dual agonist DD01 for metabolic dysfunction-associated steatotic liver disease and steatohepatitis (DD01-DN-02): 12-week results from a randomised, double-blind, multicentre, placebo-controlled, phase 2 trial.

BACKGROUND: Metabolic dysfunction-associated steatohepatitis (MASH) is a major public health problem arising in the context of metabolic syndrome and obesity. DD01 is a liver-targeted GLP-1 receptor and glucagon dual agonist being investigated for the treatment of metabolic dysfunction-associated steatotic liver disease (MASLD) and MASH. The DD01-DN-02 trial aimed to evaluate the efficacy and safety of DD01 in adults with MASLD or MASH; this initial analysis reports prespecified 12-week outcomes to assess early hepatic effects. METHODS: DD01-DN-02 is an ongoing, randomised, double-blind, multicentre, placebo-controlled, phase 2 trial conducted at 12 outpatient clinical sites in the USA. Adults aged 18-70 years with obesity or who were overweight (BMI &#x2265;25 kg/m2) were included in the study. Patients with MASLD or MASH underwent liver biopsy and MRI-proton density fat fraction (PDFF) and were eligible if liver fat content was 10% or higher with metabolic risk factors, or if the biopsy confirmed MASH with a non-alcoholic fatty liver disease activity score of at least 4. Participants were randomly assigned (1:1) to receive once-weekly subcutaneous DD01 40 mg or matched placebo over 48 weeks, dose-escalated over 2 weeks, using a centrally administered interactive response technology system. The randomisation sequence was computer-generated by an independent statistician. Participants, investigators, study staff, outcome assessors, and the sponsor were masked to treatment assignment. The primary endpoint was the proportion of participants having at least a 30% relative reduction in liver fat by MRI-PDFF at week 12, which was analysed in all randomly assigned participants receiving at least one dose of study drug or placebo. Safety analyses included all participants who received at least one dose of study drug. Missing primary endpoint data were handled using multiple imputation under a missing-at-random assumption. This trial is registered with ClinicalTrials.gov (NCT06410924) and is ongoing but closed to new participants. FINDINGS: Between June 13, 2024, and Jan 30, 2025, 67 eligible participants were enrolled, of whom 33 were randomly assigned to DD01 and 34 to placebo. The mean age of participants was 48&#xb7;4 years (SD 10&#xb7;6), 42 (63%) were female, 25 (37%) were male, 57 (85%) were White, and 52 (78%) participants had biopsy-confirmed MASH. At week 12, 25 (76%) of 33 participants receiving DD01 had a 30% or higher reduction in liver fat versus four (12%) of 34 participants receiving placebo (adjusted common odds ratio 28&#xb7;8 [95% CI 7&#xb7;2-115&#xb7;2]; adjusted relative risk 6&#xb7;3 [95% CI 2&#xb7;5-15&#xb7;9]; p<0&#xb7;0001). Treatment-emergent adverse events occurred in 28 (85%) of 33 participants receiving DD01 and 23 (68%) of 34 participants receiving placebo. The most common adverse events were nausea (18 [55%] of 33 participants assigned DD01; six [18%] of 34 participants assigned placebo), diarrhoea (nine [27%] of 33; six [18%] of 34), and vomiting (ten [30%] of 33; four [12%] of 34). Treatment-emergent adverse events led to treatment discontinuation in four (12%) of 33 participants in the DD01 group and one (3%) of 34 participants in the placebo group. Two (6%) treatment-emergent serious adverse events occurred in the DD01 group (abdominal pain and acute cholecystitis) and zero in the placebo group. No deaths occurred. INTERPRETATION: In this prespecified 12-week primary analysis, DD01 produced rapid reductions in liver fat compared with placebo, supporting further evaluation in long-term studies.

Metabolic ketosis attenuates NLRP3 inflammasome activation and is associated with improvements in hepatic steatosis and liver stiffness in MASLD: a pilot randomized controlled trial.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognized as a systemic metabolic-inflammatory disorder in which metabolic stress and innate immune activation, particularly through the NLRP3 inflammasome, contribute to disease progression. Metabolic ketosis, characterized by increased levels of circulating ketone bodies, especially &#x3b2;-hydroxybutyrate, has emerged as a promising strategy to modulate substrate utilization, inflammatory signaling, and hepatic injury. However, clinical evidence integrating molecular, metabolic, and hepatic outcomes remains limited. METHODS: In this pilot randomized controlled trial, 20 participants with newly diagnosed MASLD were randomly assigned to either a 3-month intervention with a daily C8-enriched medium-chain fatty acid formulation (m-CAP; meta-Capridin, providing approximately 20 g/day of C8) or a standardized low-carbohydrate dietary protocol. Metabolic indices, inflammatory mediators, adipokines, and hepatic enzymes were assessed. The expression of key inflammasome components (NLRP3, caspase-1, and ASC) was evaluated in peripheral blood mononuclear cells, and hepatic steatosis and liver stiffness were measured via transient elastography. RESULTS: The C8-enriched intervention was associated with increased circulating &#x3b2;-hydroxybutyrate levels, indicating the achievement of nutritional ketosis. Changes over time were observed in metabolic parameters, including fasting serum glucose (p < 0.05), HOMA-IR (p < 0.05), body fat percentage (p < 0.05), and BMI (p < 0.05). Alterations in inflammatory mediators and adipokine-related outcomes were also observed following the intervention. At the molecular level, changes in inflammasome-related markers were detected, including caspase-1 mRNA expression (p < 0.05) and NLRP3 expression at the transcriptional (p < 0.05) and protein levels (p < 0.01), whereas ASC expression remained unchanged. Changes in hepatic steatosis (p < 0.01) and liver stiffness measurements were observed following the intervention. Given the absence of significant Group &#xd7; Time interactions for several secondary outcomes, these findings should be interpreted as exploratory and hypothesis-generating. CONCLUSIONS: Induction of metabolic ketosis was associated with changes in metabolic, inflammatory, and hepatic parameters in patients with MASLD. The observed associations between ketosis, inflammasome-related markers, and noninvasive liver outcomes warrant further investigation of ketosis-based interventions as adjunctive approaches in MASLD. Larger and longer-term clinical trials are needed to confirm these findings and to determine whether short-term changes in liver stiffness reflect sustained alterations in hepatic status rather than structural fibrosis regression.

Plasticity of hepatic metabolism in Arctic char (Salvelinus alpinus) in response to cyclic hypoxia.

The emergence of cyclic hypoxia puts aquatic organisms' homeostasis under significant strain. Energetic metabolism as well as protein synthesis and folding are particularly altered during hypoxia, while reoxygenation imposes an oxidative challenge. Currently, little is known about how hypoxia-sensitive organisms respond to large oxygen fluctuations. Our previous work on Arctic char revealed that this salmonid, despite being strongly affected by acute hypoxia and reoxygenation (H/R), can successfully reestablish homeostasis, notably through adjustments to hepatic mitochondrial metabolism. However, the mechanisms underlying this acclimation remain poorly understood. We hypothesized that Arctic char remodel their hepatic proteome to optimize energy metabolism, reorganize oxygen-demanding pathways, and maintain cellular homeostasis during repeated H/R cycles. By exposing Arctic char to two or fifteen days of diel cyclic hypoxia, we confirmed this species' limited capacity to respond to acute H/R. Nevertheless, after fifteen cycles, fish adjusted their energetic metabolism through coordinated regulation of carbohydrate and lipid pathways and upregulation of amino acid metabolism. Mitochondrial metabolism was strongly reorganized, particularly at the ubiquinone-Complex III interaction level, alongside adjustments in proline utilization and protein processing. Moreover, protein processing and folding pathways were stimulated in both mitochondria and the endoplasmic reticulum. However, chronic cyclic hypoxia may still promote non-mitochondrial ROS production, DNA replication stress, and impaired immune function. This study highlights how a hypoxia-sensitive fish progressively reorganizes its metabolism and oxygen-demanding pathways to establish a phenotype adapted to chronic cyclic hypoxia, while also revealing the physiological costs associated with this acclimation.

Uric Acid-to-HDL Cholesterol Ratio is Associated with Hepatic Steatosis but Not Fibrosis in Nonobese Adults: A NHANES 2017-2020 Study.

BACKGROUND: Although metabolic dysfunction-associated steatotic liver disease (MASLD) has traditionally been regarded as a disease closely related to obesity, its prevalence is gradually rising in nonobese populations. The uric acid-to-high-density lipoprotein cholesterol ratio (UHR) is a novel metabolic biomarker that has been shown to be associated with MASLD. However, its role in nonobese individuals remains unclear. This study aimed to investigate the association between UHR and nonobese MASLD. METHODS: Data from the 2017 to 2020 National Health and Nutrition Examination Survey (NHANES) were analyzed. UHR was calculated as the serum uric acid (UA) divided by the high-density lipoprotein cholesterol (HDL). Liver steatosis (using controlled attenuation parameters, CAP) and fibrosis (using liver stiffness measurement, LSM) were evaluated through vibration-controlled transient elastography (VCTE). Multivariate linear regression was employed to evaluate associations. Nonlinear relationships were examined using smoothed curve fitting. RESULTS: This analysis included 3573 participants (47.41% male; aged 20-80 years). Log2-UHR was positively associated with CAP (&#x3b2; = 9.96, 95% CI: 6.93-12.98, P < 0.001) and MASLD prevalence (OR = 1.64, 95% CI: 1.38-1.95, P < 0.001). Subgroup analyses revealed significant interactions by sex, age, ethnicity, and smoking status (all P for interaction < 0.05), with stronger associations in females, adults aged 40-59 years, individuals of other Hispanic ethnicity, and never-smokers. Moreover, the association between log2-UHR and CAP was linear and positive (P < 0.01). No significant association was found between log2-UHR and LSM (P > 0.05). CONCLUSIONS: UHR is independently associated with hepatic steatosis but not fibrosis in nonobese US adults, suggesting its potential utility as an early risk assessment to tool. Large scale prospective studies are needed in the future to further validate the conclusions of this study.

Hepatotoxicity of OBS: A review of the emerging PFOS substitute.

As an alternative to perfluorooctanesulfonic acid (PFOS), sodium perfluorononenyl oxobenzene sulfonate (OBS) is widely used due to its cost-effectiveness. Multiple studies have shown that the liver is a classic target organ for OBS. However, there is currently no systematic review on the hepatotoxic effects of OBS. This review systematically summarizes the exposure characteristics of OBS in the environment and human populations, as well as its mechanisms of liver toxicity. In vivo studies consistently demonstrate that OBS induces hepatotoxic effects, such as hepatomegaly, vacuolization, elevated serum transaminases, and lipid dysregulation, though the manifestation of these phenotypes varies across species and exposure routes. In vitro evidence further shows that OBS reduces cell viability and survival, and triggers necrosis accompanied by inflammation. Mechanistically, oxidative stress, inflammatory signaling, and metabolism disorder are implicated. Critically, most existing work addresses subacute or subchronic exposure, leaving a gap in chronic risk assessment for long-term, low-dose OBS exposure. Moreover, mechanistic studies have focused predominantly on downstream transcriptional and signaling changes, with limited exploration of upstream epigenetic controls. Overall, this study aims to provide a comprehensive reference for future toxicological investigations and liver injury risk assessments related to OBS exposure.

Recombinant Human Thrombopoietin Reduces the Need for Platelet Transfusion in Patients With Chronic Liver Disease and Thrombocytopenia.

Chronic liver disease (CLD)-related thrombocytopenia can limit the feasibility of invasive procedures. Recombinant human thrombopoietin (rhTPO) has demonstrated a favorable safety profile without hepatotoxicity. We evaluated the efficacy and safety of rhTPO in patients with CLD-related thrombocytopenia who were undergoing elective invasive procedures. In this multicenter, randomized (2:1), double-blind, placebo-controlled phase III trial, 120 adult Chinese patients with CLD-related thrombocytopenia (platelet count <&#x2009;50 &#xd7;&#x2009;109/L) received rhTPO (n =&#x2009;80) or placebo (n =&#x2009;40) once daily for up to 5 or 7&#x2009;days. The primary endpoint was the proportion of patients with sustained platelet counts &#x2265;&#x2009;50 &#xd7;&#x2009;109/L from 24 h before invasive procedure to 7&#x2009;days post-procedure, without requiring emergency bleeding management. The primary endpoint was achieved by 85.0% of patients in the rhTPO group versus 12.5% in the placebo group (p&#x2009;<&#x2009;0.0001). Preoperatively, platelet counts &#x2265;&#x2009;50 &#xd7;&#x2009;109/L were achieved in 92.5% and 20.0% of patients in the rhTPO and placebo groups, respectively (p&#x2009;<&#x2009;0.0001). Platelet transfusion was avoided in 92.5% of rhTPO-treated patients versus 25.0% of placebo-treated patients (p&#x2009;<&#x2009;0.0001). The median duration of platelet counts &#x2265;&#x2009;50 &#xd7;&#x2009;109/L was significantly longer with rhTPO than with placebo (21.0 vs. 3.0&#x2009;days, p =&#x2009;0.0007). Treatment-related treatment-emergent adverse events (TEAEs) occurred in 12.5% of patients in both the rhTPO and placebo groups. No treatment-related serious adverse events were reported. Overall, rhTPO was effective and well tolerated in patients with CLD-related thrombocytopenia and may represent a viable therapeutic option for those undergoing elective invasive procedures.

Clinical Trial: Phase 3 Trial of Resmetirom Versus Placebo in Metabolic Dysfunction-Associated Steatohepatitis-Reanalysis of Fibrosis Stage 2-3 Subset.

BACKGROUND: Resmetirom is an oral thyroid hormone receptor beta agonist clinically used to treat metabolic dysfunction-associated steatohepatitis (MASH) among adults with stage F2 or F3 fibrosis. AIMS: Because the pivotal, 52-week, randomized, controlled, phase 3 MAESTRO-NASH trial (once-daily oral resmetirom 80 or 100&#x2009;mg or placebo) included patients with F1, F2, or F3 fibrosis, we conducted a post hoc analysis aimed at assessing treatment response in the subset of patients with stages F2 and F3 fibrosis, consistent with the approved label population. METHODS: Co-primary end points were MASH resolution (hepatocellular ballooning score 0, lobular inflammation score &#x2264;&#x2009;1, and &#x2265;&#x2009;2-point nonalcoholic fatty liver disease activity score [NAS] reduction from baseline) with no fibrosis worsening, and &#x2265;&#x2009;1-stage fibrosis improvement with no NAS worsening at Week 52. RESULTS: Among 917 patients with F2 or F3 fibrosis, metabolic risk factor prevalence was high (hypertension, 78.0%; dyslipidemia, 71.1%; type 2 diabetes, 67.0%). MASH resolution was achieved by 25.7% in the 80-mg group, 29.9% in the 100-mg group, and 9.5% in the placebo group (p&#x2009;<&#x2009;0.0001 for both comparisons with placebo). Respective percentages with fibrosis improvement were 26.5%, 28.9%, and 17.3% (p&#x2009;<&#x2009;0.01 for both comparisons). From baseline to Week 24, low-density lipoprotein cholesterol decreased by 11.7% and 13.7% in the 80- and 100-mg resmetirom groups, respectively, and increased by 2.3% with placebo (p&#x2009;<&#x2009;0.0001 for both comparisons). No new safety signals emerged. CONCLUSION: Results among patients with F2 and F3 fibrosis were consistent with the primary MAESTRO-NASH analysis population, demonstrating efficacy and safety of resmetirom after 52&#x2009;weeks.
