Special Issue Information

Dear Colleagues,

Chronic liver diseases (CLDs) have emerged as a significant cause of hepatic-related morbidity and mortality worldwide in recent years. MASLD is a complex pathology, and is considered to be the hepatic expression of metabolic syndrome (MetS). It is likely to become the main indication for liver transplantation in the coming years, as it is estimated to affect 57.5–74.0% of obese people and 52.8% of obese children, with 50% of individuals with type 2 diabetes being diagnosed with MASLD. Moreover, alcoholic liver disease (ALD) and drug-induced liver injury (DILI) result from one or a combination of genetic, environmental, and lifestyle-associated factors, such as diet-induced obesity, metabolic dysfunction, alcohol use, or drug toxicity. A late diagnosis of CLD, due to its insidious evolution and heterogeneous pathophysiology, significantly limits the use of therapeutic options that aim to improve the prognosis of disease. Therefore, the identification of disease-specific biomarkers that are related to the early detection of these conditions is crucial. We welcome the submission of articles that highlight new insights into the pathophysiologic mechanisms of CLDs and examine novel pathogenic pathways, new biomarkers, imaging diagnosis tools, and future therapies. In addition, we particularly welcome the submission of articles that analyze the influence of lifestyle and environmental factors on CLD progression. This Special Issue aims to present recent advances in research that enable the early diagnosis and personalized treatment of CLD, thus improving patient outcomes. The dissemination of current research regarding CLDs and collaboration between physicians, gastroenterologists, internists, cardiologists, diabetologists, nutritionists and endocrinologists is also required to ensure that we possess the knowledge and resources necessary to address this public health challenge.

(1) Background: Spontaneous bacterial peritonitis (SBP) is associated with a 20% mortality and is mainly caused by Gram-negative bacteria (GNB); Gram-positive bacteria (GPB) were predominant in some areas; and increased antibiotic resistance was recorded. (2) Methods: A retrospective study was performed between 2018 and 2024. The type of isolated strains, antibiotic susceptibility, and mortality (in-hospital; 30-day; 90-day; and 1-year) were estimated; multivariate analyses evaluated predictive factors for in-hospital mortality risk. (3) Results: 45 culture-positive SBP, 28 culture-negative SBP, 6 bacterascites, and 670 control ascites were diagnosed; GPB represented 60%; two Candida peritonitis and 11 polymicrobial peritonitis (21.6%) were noted (without surgery; peritoneal dialysis; or tegumentary lesion). High resistance rates to cephalosporins and quinolones, and high carbapenem resistance for nosocomial GNB were recorded. A low resistance rate to Tigecycline was noted in all infection types; GPB was susceptible to Linezolid and Vancomycin; and GNB was susceptible to Aztreonam and Colistin. In-hospital mortality was 26.7% (40% for GNB-SBP; 20% for GPB-SBP), similar to culture-negative SBP (21.3%), and higher than in the control group (9%); long-term mortality remained higher. (4) Conclusions: microbial changes to GPB etiology and increasing resistance were noted, but with a lower mortality compared to GNB; higher mortality rates up to 1 year for culture-positive and culture-negative SBP were recorded Full article

Liver cirrhosis continues to be a major global health issue, contributing to high morbidity and mortality due to its progressive nature and associated complications. This review explores recent advancements in the diagnosis and treatment of liver cirrhosis and its related syndromes. Non-invasive diagnostic tools, such as elastography and serum biomarkers, have significantly improved early detection, reducing the need for liver biopsies. Advanced imaging techniques, including MRI and CT, further enhance diagnostic accuracy. In parallel, molecular and genomic research is providing new insights into the pathogenesis of the disease, paving the way for precision medicine. On the treatment front, pharmacological innovations, such as antifibrotic agents and targeted therapies, show promise in slowing disease progression. Endoscopic interventions like variceal banding are improving the management of complications, while advancements in liver transplantation and artificial liver support systems offer life-saving alternatives. Regenerative medicine, particularly stem cell therapy and tissue engineering, is emerging as a promising strategy for liver repair. Managing cirrhosis-related syndromes, including portal hypertension, ascites, hepatic encephalopathy, and hepatorenal syndrome, now involves evolving therapeutic approaches such as transjugular intrahepatic portosystemic shunt (TIPS) and novel pharmacotherapies. Prognostic scoring systems like the MELD and Child–Pugh are being refined with new biomarkers for better risk stratification. The future of cirrhosis care will likely involve the integration of artificial intelligence and machine learning for early diagnosis and personalized treatments, alongside emerging therapies currently under investigation. Despite these advancements, challenges such as costs, accessibility, and healthcare disparities remain barriers to widespread adoption. This review highlights the importance of incorporating innovative diagnostic and therapeutic strategies into clinical practice to improve the outcomes for patients with liver cirrhosis and its complications.
