Special Issue Information

Dear Colleagues,

We are grateful to you for submitting your important contributions to the previous Special Issue, “Novel Challenges and Therapeutic Options for Digestive and Liver Diseases”, which undeniably benefited the research community. In light of this success, we now invite submissions for the second edition of this Special Issue.

The digestive system is one of the most important systems in the human body, with a major direct and indirect role in homeostasis. The digestive system includes the liver, which plays a crucial role in metabolism by interacting with nutrient stimuli and hormones.

Digestive and liver diseases have a range of viral, toxic, autoimmune, inherited and acquired causes, with complex molecular pathogeneses and various risk factors. These disorders have a high frequency worldwide, affecting an increasing number of patients. This leads to concerns regarding these diseases among the medical community.

The aim of this Special Issue is to evaluate and discuss novel challenges and therapeutic options for digestive and liver diseases, such as diagnostic challenges, differential diagnosis, prognosis, treatment, management, pharmacotherapy and outcomes.

We invite colleagues around the world to report their experience and knowledge with original studies, case series, and reviews for this Special Issue of our journal in order to support the development in this important area.

Abstract
Primary biliary cholangitis (PBC) is a heterogeneous autoimmune liver disease in which clinical presentation, disease progression, and response to therapy vary markedly from patient to patient.

Primary biliary cholangitis (PBC) is a heterogeneous autoimmune liver disease in which clinical presentation, disease progression, and response to therapy vary markedly from patient to patient. This heterogeneity reflects its complex, multifactorial, and not-completely elucidated pathogenesis. Currently, serological markers are available to non-invasively diagnose PBC, reserving liver biopsy for selected cases with atypical presentations or diagnostic uncertainty. Anyway, the accurate non-invasive prediction of liver-related and non-liver-related (i.e., extra-hepatic, including pruritus) outcomes remains an open challenge, as well as an urgent need, considering the great variability in clinical course and prognosis reported in PBC patients. Moreover, although ursodeoxycholic acid (UDCA) remains the standard first-line treatment, not all individuals respond equally, either in terms of therapeutic efficacy or timing of biochemical improvement. This further variability in treatment response underscores the inadequacy of uniform management approaches and reinforces the urgent need for personalized medicine, where treatment decisions are guided by patient-specific biological and clinical parameters. In this scenario, the identification and validation of non-invasive predictive biomarkers capable of detecting early therapeutic responsiveness are pivotal for optimizing care pathways. Finally, a growing portion of patients show an insufficient UDCA response or are UDCA intolerant, making the identification of novel strategies of care an urgent need. Concerning this, very recently, new therapeutic options beyond UDCA targeting, among the other pathways, bile acid metabolism (including the modern Peroxisome Proliferator-Activated Receptor agonists), immune regulation, and fibrogenesis, have expanded the treatment landscape. In the Era of Precision Medicine, these diagnostic, prognostic, and therapeutic innovations, by reflecting the complexity of PBC pathogenesis, underline the cruciality of a patient-tailored strategy to improve outcomes and mitigate disease progression. The present review reports recent advances, highlights ongoing challenges, and outlines future perspectives in the management of PBC. Full article

Background/Objectives: Ulcerative colitis (UC) is a part of inflammatory bowel disease (IBD) and it is characterized by colonic-mucosal chronic inflammation with intermittent clinical activity. Personalized medicine is becoming more and more a relevant method of approach in this field, and the identification of potential concerns in a single patient may contribute to the improvement of the clinical approach. Mesalamine represents the cornerstone of therapy for mild–moderate disease forms, but non-adherence to medical therapy represents a critical health problem, although it is underestimated by many physicians, with evident consequences in terms of disease-related complications. The aim of the present study is to evaluate the magnitude of non-adherence to oral mesalamine in UC patients performing a systematic review and meta-analysis of literature. Methods: A literature search in PubMed and Cochrane databases was performed for studies reporting the non-adherence rate to oral mesalamine in adult UC patients, and eligible studies have been selected for evaluation. The type of study (trial vs. observational), geographic area, sample size, method of adherence assessment, and non-adherence rate were considered. Results: From a total of 464 articles, 34 studies were included in the meta-analysis after selection. Sixteen studies (47%) are observational, and eighteen (53%) are clinical trials. A total of 12/34 (35%) studies are from North America, 14/34 (41%) from Europe, 4/34 (12%) from Asia, with 4/34 (12%) from mixed areas of the world. The mean non-adherence rate was 32%, but with a consistent variability among the studies. In particular, the non-adherence rate was significantly higher in observational studies vs. clinical trials (47 vs. 20%, p < 0.001), and in North American vs. European and Asian studies (54 vs. 23 vs. 4%, respectively, p < 0.001). Conclusions: The non-adherence rate to oral mesalamine is variably reported in the literature due to the inhomogeneity of available studies, but it represents a consistent problem, often neglected, that deserves future research. A personalized approach by a physician to a single patient can improve the effectiveness of medical therapy and the management of UC patients. Full article
