Background/Objectives: Chronic liver diseases (CLDs), including viral hepatitis, alcohol-related liver disease, non-alcoholic fatty liver disease, hepatic fibrosis, and hepatocellular carcinoma, account for approximately two million deaths annually and remain a global health challenge. Although phytochemicals exhibit antioxidant, anti-inflammatory, antifibrotic, and metabolic regulatory activities through modulation of Nrf2/Keap1, NF-κB/MAPK, TGF-β/Smad, and lipid metabolism pathways, their therapeutic translation is hindered by poor aqueous solubility, extensive first-pass metabolism, and low oral bioavailability. This review evaluates the potential of liposomal delivery systems to overcome these limitations and improve hepatic drug targeting. Methods: A structured narrative review was conducted using systematic literature search principles. PubMed/MEDLINE, Scopus, and Web of Science databases were searched for studies published between January 2000 and March 2025. Original research articles evaluating liposomal formulations of hepatoprotective phytochemicals were assessed with emphasis on formulation strategies, pharmacokinetics, therapeutic efficacy, targeting approaches, and translational potential. Results: Liposomal encapsulation frequently improved systemic exposure and, in several preclinical studies, increased oral bioavailability relative to free phytochemicals, although the magnitude of improvement varied substantially according to the compound, formulation, route of administration, and experimental model. Liposomal encapsulation also improved formulation stability and enabled controlled release in several studies. Surface engineering using polyethylene glycol and receptor-specific ligands, including galactose, lactobionic acid, glycyrrhetinic acid, and vitamin A, further improved circulation time and cell-specific hepatic delivery. Emerging technologies such as microfluidic manufacturing, biomimetic liposomes, and multifunctional formulations show promise for improving formulation reproducibility and therapeutic performance, although clinical evidence remains limited. Conclusions: Liposomal delivery represents a promising strategy for enhancing the pharmacokinetic performance and therapeutic efficacy of hepatoprotective phytochemicals. However, additional well-designed clinical studies, scalable manufacturing approaches, and regulatory standardization are required to facilitate successful clinical translation. Full article

Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection remain leading causes of cirrhosis and hepatocellular carcinoma (HCC) worldwide, and continue to represent a major challenge despite the growing contribution of alcohol-related and metabolic dysfunction-associated steatotic liver disease. Direct-acting antivirals now cure most patients with chronic HCV infection, while nucleos(t)ide analogues durably suppress HBV replication, producing a rapidly expanding population of treated and cured patients. Many nonetheless retain residual fibrosis, portal hypertension and long-term cancer risk, creating a need for non-invasive long-term liver assessment. Multiparametric ultrasound (MPUS) integrates the evaluation of morphology, fibrosis, steatosis, haemodynamics and perfusion within a single examination. This narrative review summarises the evidence supporting MPUS in chronic viral hepatitis, covering elastographic fibrosis assessment, Baveno VII liver and spleen stiffness criteria for clinically significant portal hypertension, contrast-enhanced ultrasound characterisation of focal liver lesions, and emerging techniques such as microvascular and viscosity-sensitive imaging. Particular attention is given to the confounding effect of inflammatory activity on liver stiffness. MPUS is presented here as a proposed evaluation framework for organising complementary measurements within a single examination, and not as an approach of demonstrated clinical superiority: no comparative or outcome-based study has yet shown that acquiring these parameters together improves clinical decisions relative to the individual techniques applied according to current guidelines. Within this framework, the most plausible role of MPUS in the elimination era is longitudinal assessment of the treated liver, a proposition that requires prospective validation against clinical endpoints.

Hepatitis C virus (HCV) infection is a major cause of chronic hepatitis, affecting approximately 50 million people worldwide. An estimated 15–30% of individuals with chronic HCV infection progress to cirrhosis, which may subsequently develop into hepatocellular carcinoma. Beyond liver disease, HCV is associated with a broad spectrum of extrahepatic manifestations, particularly mixed cryoglobulinemia (MC) and B-cell non-Hodgkin lymphoma (B-NHL). Persistent viral infection induces chronic antigenic stimulation of B lymphocytes, a key pathogenic mechanism underlying the progression from MC to overt B-NHL. These observations have important therapeutic implications and support the use of antiviral therapy as a cornerstone of treatment. The efficacy of direct-acting antivirals (DAAs) has been well established in patients with HCV-related MC and cryoglobulinemic vasculitis. Several studies have shown that DAAs achieve sustained virologic response rates exceeding 90%, often approaching 100% in contemporary cohorts. Viral eradication is frequently associated with clinical and immunological improvement, as well as regression of cryoglobulinemia. Encouraging outcomes have also been reported in patients with HCV-associated indolent B-NHL, particularly marginal zone lymphoma, although confirmation in larger studies with longer follow-up is needed. In patients with HCV-positive aggressive lymphomas, DAAs have been safely administered in combination with immunochemotherapy, yielding promising results. This review summarizes the current evidence on HCV-associated MC and B-NHL and discusses the impact of DAA therapy on the clinical course and management of these disorders. Full article

Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. Although the STRIDE regimen (durvalumab plus tremelimumab) has demonstrated an overall survival benefit in clinical trials, real-world evidence remains limited, particularly in Turkish clinical practice. This study aimed to evaluate the effectiveness and safety of first-line STRIDE therapy in patients with unresectable HCC treated in routine clinical practice. Methods: We conducted a retrospective multicenter study including patients with unresectable HCC who received first-line durvalumab plus tremelimumab through the Turkish national Early Access Program across 18 oncology centers. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan–Meier method, and exploratory Cox regression analyses were performed to evaluate baseline prognostic factors. Results: Thirty-two patients were included. The median PFS was 7.25 months (95% CI, 3.68–22.29), and the median OS was 11.43 months (95% CI, 4.50–not reached). The underlying liver disease etiology was non-viral in 53.1% of patients, hepatitis B virus in 40.6%, and hepatitis C virus in 6.3%. Grade ≥ 3 treatment-related adverse events occurred in fewer than 10% of patients. Conclusions: In this multicenter real-world cohort, first-line durvalumab plus tremelimumab appeared to be a feasible treatment option and was generally well tolerated in patients with unresectable HCC. However, given the retrospective design, small sample size, and absence of a control group, these findings should be interpreted cautiously and require confirmation in larger prospective comparative studies.

Aflatoxin B₁ (AFB₁), a dietary mycotoxin classified as a Group 1 carcinogen and a risk factor for hepatocellular carcinoma (HCC), has seen limited biomarker-based evidence linking it to HCC in South America despite favorable regional contamination conditions. Utilizing a newly validated isotope-dilution HPLC–MS/MS method to quantify AFB₁-Lysine (AFB₁-Lys) adducts, we conducted a cross-sectional study involving 92 HCC patients and 70 healthy controls across six South American nations. The primary case–control analysis, focusing on 64 HCC patients and 70 controls from Argentina and Colombia, revealed that AFB₁-Lys concentrations and positivity rates were significantly higher in HCC cases compared to controls (7.16 vs. 0.89 pg/mg albumin; 43% vs. 10%). Multivariable logistic regression demonstrated that detectable AFB₁-Lys was significantly and independently associated with HCC (adjusted OR = 3.72), with associations most pronounced, though based on small subgroups, in viral hepatitis-related and cryptogenic HCC. Furthermore, broader regional analysis indicated higher AFB₁-Lys positivity rates in HBV-positive patients than in HCV-positive or non-viral HCC cases. Ultimately, chronic dietary aflatoxin exposure shows a consistent, statistically significant association with hepatocarcinogenesis across diverse etiological backgrounds in South America, highlighting an urgent need for integrated regional food safety surveillance and expanded prospective studies.

Background and Objectives: In Taiwan, hepatitis B virus (HBV) or hepatitis C virus (HCV) infections are the most common causes of hepatocellular carcinoma (HCC). However, an increasing number of non-HBV and non-HCV (NBNC) patients developing HCC has been noted in recent years. The pathogenic connection between NBNC status and HCC development remains largely elusive. This study aims to explore the differences in clinical manifestations and pathological findings among HCC patients with HBV, HCV, and NBNC etiologies. Methods: This retrospective study analyzed 521 HCC patients with complete hepatic viral profiles at a single medical center in Taiwan between 2016 and 2020. Differentially expressed gene (DEG) analysis, xCell stromal cell estimation, and Gene Set Enrichment Analysis (GSEA) were employed to explore the distinct oncogenic mechanisms between the viral and NBNC groups. Results: The final cohort included 38 NBNC-HCC patients. Clinically, the NBNC-HCC patients exhibited a significantly lower FIB-4 index than the HCV-HCC patients (3.191 vs. 6.077, p = 0.0019). Furthermore, fewer NBNC-HCC patients presented with imaging-defined cirrhosis compared to HBV-HCC patients (44.4% vs. 68.1%, p = 0.0057), and a lower proportion had high Ishak scores (5–6) compared to HCV-HCC patients (31.3% vs. 75.6%, p = 0.0025). DEG analysis revealed differential expression in oncogenes (OIT3, AKR1B10) and liver fibrosis-related genes (COLEC10, CXCL14, and LINC01093). Subsequent GSEA and stromal cell analyses highlighted significant differential enrichment in hepatic stellate cells and vascular endothelial cells. Conclusions: NBNC-HCC patients present with significantly lower rates of cirrhosis and fibrosis compared to their viral counterparts. The distinct gene expression profiles and cell-type enrichment features observed between the viral and NBNC groups indicate a divergent, etiology-specific pathogenesis driving NBNC-HCC. Full article

Background/Objectives: Hepatocellular carcinoma (HCC) arises through heterogeneous pathways involving chronic hepatitis B virus infection, hepatitis C virus infection, alcohol-related liver disease, metabolic dysfunction-associated steatotic liver disease, fibrosis, cirrhosis, and environmental exposures. Genome-wide association studies (GWASs) have identified host germline loci associated with HCC susceptibility, but interpretation is complicated by aetiology, ancestry, liver disease stage, and the definition of controls. This narrative review examines current GWAS evidence for HCC, with emphasis on aetiology-specific susceptibility, functional interpretation, cross-disorder genetic effects, and clinical translation. Methods: Studies were identified through iterative searches of PubMed/PMC, publisher pages, academic search tools, and citation tracking, supplemented by targeted searches for major HCC-associated loci. Sources were chosen based on relevance to GWAS discovery, replication, meta-analysis, functional interpretation, polygenic risk modelling, or HCC risk stratification, rather than by a formal systematic review protocol. Results: Viral HCC studies most often implicate immune regulation and antigen presentation, including MICA, HLA-DQ, HLA-DQB1, HLA class I, HCP5, STAT4, DEPDC5, and FAM114A1. Alcohol-related, metabolic, and non-viral HCC studies more often implicate hepatic lipid metabolism, telomere biology, iron metabolism, steatosis, and cirrhosis-related pathways, including PNPLA3, TM6SF2, TERT, HSD17B13, APOE, HFE, and MTARC1. Recent studies increasingly combine GWASs with fine-mapping, functional annotation, transcriptomic analyses, and risk modelling. Conclusions: HCC genetic susceptibility is highly aetiology-specific and overlaps with other liver and metabolic disorders, but discoveries from genetic studies have not yet been translated into routine clinical practice. Future work should prioritise multi-ancestry cohorts, disease-stage-aware controls, functional validation, and prospectively tested genetic risk models. Full article

Background: Chronic hepatitis B virus (HBV) infection remains a major global health challenge and a leading cause of liver cirrhosis and hepatocellular carcinoma. Interleukin-6 (IL-6), a key pro-inflammatory cytokine, plays an important role in immune regulation and hepatic inflammation. However, its relationship with HBV viral load and disease severity remains incompletely understood. Methods: A hospital-based cross-sectional study was conducted among 293 HBsAg-positive patients. Serum IL-6 levels were measured using ELISA, and HBV DNA was quantified using real-time quantitative PCR. Patients were stratified according to viral load. Statistical analyses included non-parametric tests, Spearman correlation, principal component analysis (PCA), and multiple linear regression. Results: The median age was 45 years (IQR: 34–57), among which 54.6% were male. The median HBV DNA was 3.37 log₁₀ IU/mL (IQR: 2.45–3.75), and IL-6 concentration was 2.38 log₁₀ pg/mL (IQR: 2.21–2.49). IL-6 levels increased significantly across viral load categories (p < 0.001) and were higher in HBeAg-positive patients (p = 0.002), with no significant differences across age, sex, or cirrhosis. IL-6 levels correlated with HBV DNA (r = 0.40, p < 0.001). PCA identified distinct viral-inflammatory and biochemical axes. Regression analysis confirmed HBV DNA as the significant independent predictor (β = 0.461, p < 0.001; adjusted R² = 0.206). Conclusion: IL-6 was closely associated with HBV DNA levels, while the association with conventional biochemical markers of hepatocellular injury was significantly less in this cohort, suggesting that IL-6 may serve as an adjunct biomarker of disease activity in patients with chronic hepatitis B.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and its progressive inflammatory form, metabolic dysfunction-associated steatohepatitis (MASH), are increasingly recognized as key drivers of hepatocellular carcinoma (HCC). Unlike HCC caused by viral infections or alcohol, MASLD/MASH-related liver cancer develops within a chronic immunometabolic environment characterized by lipotoxicity, sterile inflammation, fibrogenesis, and remodeling of the microenvironment. In this setting, interleukin-10 (IL-10) has attracted growing attention due to its complex, context-dependent roles in immune regulation and tumor immune tolerance. This review explores IL-10 biology and its connection to MASLD/MASH-associated HCC, emphasizing the paradox that IL-10 may diminish harmful inflammation in early stages while promoting immunosuppressive conditions in advanced disease. To supplement existing research, we performed an exploratory reanalysis of publicly available bulk liver RNA-seq data from a mouse model that progresses from MASLD/MASH to HCC. The reanalysis revealed a receptor- and effector-specific rewiring of the IL-10 pathway: while the expression of canonical signaling genes (Stat3, Jak1, Jak2, Tyk2, Socs3) showed minimal changes across stages, receptor subunits (Il10ra, Il10rb) and IL-10-responsive effectors (such as Scd2, related to lipid metabolism, and Ddit4, involved in mTOR and glycolysis regulation) displayed strong stage-dependent induction. This was accompanied by a decrease in hepatocyte signature profiles and an increase in stromal and immune signatures. These results generate new hypotheses and raise key questions—particularly whether a large portion of IL-10 modulation originates from peripheral or non-parenchymal sources, and whether the transcriptional patterns observed reflect protein-level changes—that will require stage-specific, cell-focused human studies incorporating proteomic and cytokine measurements.

Background/Objectives: Chronic liver diseases, including metabolic dysfunction-associated steatohepatitis (MASH) and chronic viral hepatitis (CVH), are major global health concerns due to their potential progression to cirrhosis, liver failure, and hepatocellular carcinoma. Because liver biopsy, despite meeting the diagnostic gold standard, is invasive and associated with complications, non-invasive fibrosis assessment tools have been increasingly recommended in clinical practice. This study aimed to compare the diagnostic performance of several non-invasive fibrosis markers (ARR, APRI, FI, FIB-4, API, NFS, BARD) and transient elastography in detecting advanced liver fibrosis (F4) in patients with MASH and CVH. Methods: This retrospective study included 237 adult patients (77 MASH, 160 CVH) who underwent liver biopsy between 2017 and 2025 at the University Clinical Center of Serbia. CVH included chronic hepatitis B (CHB) and C (CHC). Patients were evaluated using serum fibrosis indices and TE, and results were compared to histological staging (F0–F4). ROC analysis assessed diagnostic performance. Results: Cirrhosis (F4) was more common in CVH than MASH (p < 0.001). In MASH, NFS (AUROC 0.931), FIB-4 (0.915), BARD (0.872), and APRI (0.878) showed high diagnostic accuracy for F4. In CHC, APRI (0.931), FIB-4 (0.863), and TE (0.938) had strong performance, while in CHB, TE (0.987) outperformed FIB-4 (0.821). Sensitivity and specificity varied by test and cohort, with TE consistently yielding the best results where available. Conclusions: Non-invasive methods, particularly NFS and FIB-4 for MASH and TE for CVH, effectively identify advanced fibrosis. Their application could significantly reduce the need for biopsy, especially in high-risk groups. TE demonstrated superior accuracy, but access limitations highlight the continued relevance of serum-based scores. Full article

Hepatocellular carcinoma (HCC) remains a major global health burden, with an increasing incidence driven by metabolic syndrome-related cases. Early detection is critical; however, current diagnostic tools, including ultrasonography and alpha-fetoprotein (AFP), lack adequate sensitivity and specificity, particularly for non-viral HCC. In this “discovery-stage” study, we identified CD98, a transmembrane oncoprotein, as a robust biomarker highly expressed across all HCC stages, independent of etiological factors. CD98 is enriched on extracellular vesicles (EVs) released by HCC cells and can be accurately quantified using Blu-ray-based ExoCounter technology. In plasma samples from patients with early-stage (stage I/II) non-viral HCC (n = 136) and healthy controls (n = 50), CD98+ EV levels were significantly elevated (p < 0.001) and demonstrated strong diagnostic performance (AUC = 0.743; sensitivity 64%, specificity 86%). Importantly, CD98+ EV levels detected small tumors (≤3 cm) with 59% sensitivity, outperforming AFP (33%). These findings highlight circulating CD98+ EVs as a promising, noninvasive biomarker for early non-viral HCC detection, providing a clinically applicable platform that integrates EV quantification with a novel anti-CD98 monoclonal antibody for precision oncology.

Background: HIMALAYA demonstrated that STRIDE (Single Tremelimumab Regular Interval Durvalumab) significantly improved overall survival (OS) compared with sorafenib in participants with unresectable hepatocellular carcinoma (HCC). This retrospective, real-world cohort study evaluated outcomes with STRIDE in veterans with HCC. Methods: Patients diagnosed with HCC between 1 January 2008 and 28 February 2024 who received ≥1 dose of STRIDE for unresectable disease were included. Data were collected from the Veteran Affairs Corporate Data Warehouse. Safety and efficacy were evaluated overall and for subgroups of patients with Child–Pugh A versus Child–Pugh B cirrhosis, viral versus non-viral HCC, and those with versus without prior non-systemic therapies. Results: Overall, 107 patients (100.0% male) were included. Median (interquartile range) age was 72.2 (68.0–76.1) years. There were 22 Grade 3–4 adverse events reported (three in patients with Child–Pugh B cirrhosis). Median OS (95% CI) was 12.4 (9.1–22.1) months and 5.2 (1.5–9.3) months in patients with Child–Pugh A (n = 81; 75.7%) and Child–Pugh B cirrhosis (n = 26; 24.3%), respectively. In patients with viral (n = 64; 59.8%) versus non-viral etiology (n = 43; 40.2%), median OS (95% CI) was 10.5 (7.0–25.6) months versus 9.0 (4.6–16.0) months, respectively. In patients without (n = 30; 28.0%) versus with prior non-systemic therapies (n = 77; 72.0%), median OS (95% CI) was 7.7 (2.8–17.3) months versus 11.1 (7.6–17.6) months, respectively. Conclusions: These results suggest that STRIDE is well tolerated and may offer a survival benefit to a broad range of patients with unresectable HCC, representing populations that are more reflective of real-world clinical practice.

A compelling body of evidence links pesticide exposure to human diseases. The liver plays a central role in the detoxification of pesticides, suggesting intense pesticide–liver cell interactions. A growing body of studies highlighted in this review supports the contribution of pesticides of various chemical classes to the development of non-alcoholic fatty liver disease (NAFLD), alcohol-associated liver disease (ALD), liver cirrhosis, viral hepatitis, hepatocellular carcinoma, etc., via disrupting lipid and carbohydrate metabolism and redox homeostasis, promoting endoplasmic reticulum stress and mitochondrial dysfunction, as well as stimulating apoptosis, fibrosis, and inflammation. In this review, we systematically illustrated an underappreciated mechanism of pesticide-induced overall and hepatic toxicity, i.e., the ability to induce non-apoptotic regulated cell death (RCD) pathways such as ferroptosis, necroptosis, and pyroptosis. Our analysis indicates that pesticides are implicated in driving liver diseases by inducing ferroptosis, necroptosis, and pyroptosis. Non-apoptotic RCDs mediate pesticide-induced liver steatosis and fibrosis. Furthermore, these cell death modalities fuel inflammation through the promotion of pro-inflammatory cytokine production and the generation of damage-associated molecular patterns. Understanding of deeper mechanisms of pesticide-induced effects on the non-apoptotic cell death machinery and subsequent immunogenic effects in liver pathology might help develop novel preventive strategies to reduce liver damage.

Chronic hepatitis delta is the most severe form of viral hepatitis and is associated with rapid progression to cirrhosis and hepatocellular carcinoma. Although bulevirtide (BLV) effectively inhibits hepatitis D virus (HDV) entry, immunological biomarkers reflecting treatment response and residual viral activity remain poorly defined. This study investigated the serum profiles of interleukin-37 (IL-37) and IL-36 isoforms (IL-36α, IL-36β, and IL-36γ) in 22 HBV/HDV-coinfected patients receiving BLV monotherapy (2 mg/day). Serum cytokine levels were measured by ELISA at baseline (BL) and after 48 weeks of BLV treatment (TW48) and compared with HBV-monoinfected patients under nucleos(t)ide-analogue therapy and healthy donors. Patients were stratified according to virological, biochemical, and combined responses. At both BL and TW48, serum IL-37, IL-36α, and IL-36β levels were significantly higher in HBV/HDV-coinfected patients than in comparison groups (all p < 0.05), independent of treatment response, indicating a persistent cytokine signature during BLV therapy. IL-36β levels significantly decreased over time, particularly in biochemical non-responders (p = 0.0469), whereas IL-36α remained elevated and differed at TW48 between combined responders and non-responders (p = 0.0400). IL-36γ was detectable only in a small subset of patients. Notably, in a subgroup of patients evaluated at week 96, baseline IL-37 levels were significantly lower in those achieving virological response compared with non-responders (p = 0.0275). Moreover, IL-37 was the only cytokine showing a significant positive correlation with HDV RNA levels at TW48 when quantified by the AltoStar^® assay (p = 0.033; R² = 0.7563). Overall, HBV/HDV-coinfected patients display a distinct IL-37/IL-36 cytokine profile during BLV therapy. The association between IL-37 and residual viremia supports further investigation of this cytokine as a complementary biomarker for monitoring low-level viral activity during treatment. Full article

Background: Chemokine CCL5 may drive inflammation and vascular risk in advanced liver disease, but its cardiovascular implications are unclear. Secreted by hepatic, endothelial, macrophage, and lymphocytic cells, CCL5 is involved in cytokine regulation. Its serum levels rise in acute liver injury and hepatocellular carcinoma (HCC), but decline with fibrosis progression in end-stage liver disease (ESLD). CCL5 has also been linked to atherosclerosis. This study aimed to evaluate serum CCL5 levels in ESLD patients listed for liver transplantation (LT) and to assess their potential role as markers of cardiovascular (CV) risk and portal hypertension. Methods: We conducted an observational cohort study. Between 2019 and 2022, patients with ESLD evaluated for LT were enrolled. Data on liver pathology, CV risk, and laboratory parameters were collected. Serum CCL5 concentrations were measured using Sigma Aldrich^® CCL5 ELISA kits (MilliporeSigma, St. Louis, MO, USA). The database was analyzed with IBM^® SPSS^® Statistics version 20 (Chicago, IL, USA). Results: Overall, 46 patients were included, 50% with viral hepatitis and 28.3% with alcohol-related liver disease. HCC was present in 37% of cases. The median CV risk scores (CAD_LT = 7, mCAD_LT = 7, CAR_OLT = 18) placed the population at moderate CV risk. Serum CCL5 levels did not vary significantly between viral vs. non-viral cirrhosis (5511.8 vs. 6272.5 pg/mL, p = 0.15) and were not influenced by the presence of HCC (6098.4 vs. 5771.3 pg/mL, p = 0.55). We did not detect a correlation with MELD score (p = 0.21) or CV risk scores (CAD_LT: p = 0.58; mCAD_LT: p = 0.70; CAR_OLT: p = 0.22). Patients with thrombocytopenia (<100,000/µL, 54.3%) or a history of esophageal variceal ligation had lower CCL5 levels (5170.9 vs. 6750.8 pg/mL, p = 0.002 and 4252.0 vs. 6237.5 pg/mL, p = 0.003, respectively). Similarly, patients with a history of previous variceal bleeding and spontaneous bacterial peritonitis (SBP) had lower levels of CCL5 (4373.8 vs. 6119.9 pg/mL, p = 0.02 and 3404.3 vs. 6606.7 pg/mL, p = 0.01, respectively). We found a negative correlation between CCL5 and QTc interval duration (τ = −0.216, p = 0.037), left ventricle size (LV: τ = −0.235, p = 0.027), and pulmonary artery pressure (RV/RA gradient: τ = −0.225, p = 0.03). CCL5 correlated positively with the inflammatory markers C-reactive protein (CRP) (τ = 0.246, p = 0.018) and fibrinogen (r = 0.216, p = 0.04). Conclusions: In liver transplant candidates, serum CCL5 is not associated with cardiovascular risk scores or coronary atherosclerotic burden, but is inversely associated with clinical markers of portal hypertension severity. These findings suggest that CCL5 may serve as a potential non-invasive surrogate marker of portal hypertension rather than a cardiovascular risk biomarker in ESLD. Full article
