Recently, metabolic associated steatotic liver disease (MASLD) became the leading cause of chronic liver disease worldwide and one of the most frequent causes of hepatocellular carcinoma (HCC). Nonetheless, in this epidemiological trend, viral hepatitis remains the major driver in hepatic carcinogenesis. Globally, hepatitis B virus (HBV) is the leading cause of hepatocellular carcinoma, with an overall attributable risk of approximately 40%, followed by hepatitis C virus (HCV), which accounts for 28–30% of cases, with significant geographic variations between the Eastern and Western world. Considering all the etiologies, HCC risk increases proportionally with the progression of liver disease, but the risk is consistently higher in patients with viral triggers. This evidence indicates that both direct (due to the oncogenic properties of the viruses) and indirect (through the mechanisms of chronic inflammation that lead to cirrhosis) mechanisms are involved, alongside the presence of co-factors contributing to liver damage (smoking, alcohol, and metabolic factors) that synergistically enhance the oncogenic process. The aim of this review is to analyze the oncogenic role of hepatitis viruses in the liver, evaluating epidemiological changes and direct and indirect viral mechanisms that lead to liver cancer.

Worldwide, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) significantly increases mortality and morbidity. The Coronavirus Disease 2019 (COVID-19) outbreak has had a considerable impact on healthcare systems all around the world, having a significant effect on planned patient activity and established care pathways, in order to meet the difficult task of the global pandemic. Patients with hepatocellular carcinoma (HCC) are considered a particularly susceptible population and conceivably at increased risk for severe COVID-19 because of two combined risk factors: chronic advanced liver disease and HCC itself. In these challenging times, it is mandatory to reshape clinical practice in a prompt way to preserve the highest standards of patient care and safety. However, due to the stay-at-home measures instituted to stop the spread of COVID-19, HCC surveillance has incurred a dramatic drop, and care for HCC patients has been rearranged by refining the algorithm for HCC treatment to the COVID-19 pandemic, permitting these patients to be safely managed by identifying those most at risk of neoplastic disease progression.
Irritable bowel syndrome (IBS) is a gut–brain axis chronic disorder, characterized by recurrent abdominal pain and altered bowel habits in the absence of organic pathology. Nutrition plays a central role in symptom management, yet no single dietary strategy has demonstrated universal effectiveness. This narrative review critically evaluates current nutritional approaches to IBS. The low-Fermentable Oligo-, Di-, Mono-saccharides and Polyols (FODMAP) diet is the most extensively studied and provides short-term symptom relief, but its long-term effects on microbiota diversity remain concerning. The Mediterranean diet, due to its anti-inflammatory and prebiotic properties, offers a sustainable, microbiota-friendly option; however, it has specific limitations in the context of IBS, particularly due to the adverse effects of certain FODMAP-rich foods. A gluten-free diet may benefit individuals with suspected non-celiac gluten sensitivity, although improvements are often attributed to fructan restriction and placebo and nocebo effects. Lactose-free diets are effective in patients with documented lactose intolerance, while a high-soluble-fiber diet is beneficial for constipation-predominant IBS. IgG-based elimination diets are emerging but remain controversial and require further validation. In this review, we present the 10 dietary commandments for IBS, pragmatic and easily retained recommendations. It advocates a personalized, flexible, and multidisciplinary management approach, avoiding rigidity and standardized protocols, with the aim of optimizing adherence, symptom mitigation, and health-related quality of life. Future research should aim to evaluate, in real-world clinical settings, the impact and applicability of the 10 dietary commandments for IBS in terms of symptom improvement and quality of life
Cholangiocarcinoma (CCA), a highly heterogeneous cancer, is the second most common type of primary liver cancer. It is characterized by resistance to therapy and poor prognosis, with a 5-year survival rate lower than 20%. The pathogenesis of CCA is complex and multifactorial, and in recent years, bile acids (BAs) have been implicated in CCA development and prognosis. BAs belong to a category of amphipathic compounds that hold significant importance as signaling molecules and inflammatory agents. They possess the ability to activate transcriptional factors and cellular signaling pathways, thereby governing the regulation of lipid, glucose, and energy metabolism in diverse human disorders. These disorders encompass chronic liver diseases among other conditions. In this review, we provided an update on the current knowledge on the molecular mechanisms involving BAs in cholangiocarcinogenesis. Additionally, we analyzed the role of gut and biliary microbiota in CCA pathogenesis. Future research is required to better understand how to modulate BA activity and, possibly, identify new therapeutic strategies.
The low response to vaccines is a well-known problem in cirrhosis. We evaluated the safety and immunogenicity of booster doses in patients with chronic liver disease (CLD), comparing the humoral response in cirrhotic vs. non-cirrhotic patients, and the impact of different factors on immune response. From September 2021 to April 2022, outpatients with CLD who completed the primary vaccination course and the booster dose against SARS-CoV-2 were enrolled. Blood samples were collected after second and third doses for detecting anti-spike protein IgG. We enrolled 340 patients; among them, 91 subjects were cirrhotic. After primary vaccination course, 60 (17.6%) patients did not develop a positive antibody titer, without significant differences between cirrhotic and non-cirrhotic patients (p = 0.076); most of them (88.3%) developed it after booster dose. At multivariable analysis, factors associated with higher humoral response after booster dose were only porto-sinusoidal vascular disorder (p = 0.007) as an etiology of CLD and the use of the mRNA-1273 vaccine (p = 0.001). In conclusion, in patients with CLD, a booster dose against SARS-CoV-2 induces an excellent immunogenicity and leads to an adequate antibody response. Cirrhosis is not associated with a worse humoral response, compared to patients with non-cirrhotic CLD.
For patients with single small (≤3 cm) hepatocellular carcinoma ablation is the first-line treatment, although a high rate of recurrence has been reported. The aim was to compare videolaparoscopic liver resection (laparoscopic resection group) vs. percutaneous thermoablation (ablation group) in terms of overall survival, recurrence-free survival and early recurrence in a real-life national scenario. The study is a retrospective collection with subsequent survival analysis. Data were collected from two Italian HCC registries, ITA.LI.CA and HE.RC.O.LE.S. An inverse probability of treatment weighting analysis was performed to balance baseline differences between groups. The Kaplan–Meier method and double-robust Cox multivariable regression were run to estimate the survival and the risk of mortality and recurrence. Between 2008 and 2022, 1,465 patients were enrolled. The laparoscopic resection group and ablation group consisted of 496 and 969 patients, respectively. At baseline, the ablation group had more advanced liver disease, with higher rates of cirrhosis (90.7% vs. 77.3%, p <0.001) and Child-Pugh B status (18.4% vs. 8.8%, p <0.001). After a median follow-up of 59 months and after weighting median overall survival was 60 months (95% CI 52–66) for the ablation group and 93 months (95% CI 75–110) for the laparoscopic resection group (hazard ratio [HR] 0.607, 95% CI 0.533–0.691, p <0.001). Median recurrence-free survival was 26 months (95% CI 23–29) for the ablation group and 39 months (95% CI 30–55) for the laparoscopic resection group (HR 0.736, 95% CI 0.659–0.822, p = 0.0013). Laparoscopy was associated with a reduced risk of early recurrence (HR 0.747, 95% CI 0.655–0.853, p = 0.011). This study provides real-world evidence that for patients with single ≤3 cm HCC, videolaparoscopic liver resection offers superior long-term oncological outcomes compared with thermoablation. These findings support the preference for surgical treatment in this patient population. Percutaneous thermoablation is considered an appropriate alternative to liver resection for small (≤3 cm) single hepatocellular carcinoma because of not-inferior overall survival, although several authors reported increased recurrence risk. Whether videolaparoscopic liver resection could guarantee comparable survival but superior oncologic control of the disease is a matter of debate. This study comparing videolaparoscopy vs. thermoablation in a large national cohort of 1,465 patients observed that the former guaranteed significant prolonged OS (93 months [95% CI 75–110] vs. 60 months [95% CI 52–66] for the ablation group) and recurrence-free survival (26 months [95% CI 23–29] for ablation patients and 39 months [95% CI 30–55] for laparoscopic resection patients) even after weighting all the preoperative and oncologic differences among the groups. Our results clearly address the need to rethink the role of thermoablation for single small HCC as a second-line treatment when laparoscopic liver resection is not feasible.
