The Contribution of Genetic and Epigenetic Factors: An Emerging Concept in the Assessment and Prognosis of Inflammatory Bowel Diseases.

Inflammatory bowel disease (IBD) represents heterogeneous and relapsing intestinal conditions with a severe impact on the quality of life of individuals and a continuously increasing prevalence. In recent years, the development of sequencing technology has provided new means of exploring the complex pathogenesis of IBD. An ideal solution is represented by the approach of precision medicine that investigates multiple cellular and molecular interactions, which are tools that perform a holistic, systematic, and impartial analysis of the genomic, transcriptomic, proteomic, metabolomic, and microbiomics sets. Hence, it has led to the orientation of current research towards the identification of new biomarkers that could be successfully used in the management of IBD patients. Multi-omics explores the dimension of variation in the characteristics of these diseases, offering the advantage of understanding the cellular and molecular mechanisms that affect intestinal homeostasis for a much better prediction of disease development and choice of treatment. This review focuses on the progress made in the field of prognostic and predictive biomarkers, highlighting the limitations, challenges, and also the opportunities associated with the application of genomics and epigenomics technologies in clinical practice.

Clinical Implications and Management of Spontaneous Portosystemic Shunts in Liver Cirrhosis.

Portal hypertension from chronic liver disease leads to the formation of collateral blood vessels called spontaneous portosystemic shunts (SPSS). These shunts may form from existing vessels or through neo-angiogenesis. Their location affects clinical outcomes due to varying risks and complications. This review summarizes current knowledge on SPSS, covering their clinical impact and management strategies. Recent data suggest that SPSS increases the risk of variceal bleeding, regardless of shunt size. The size of the shunt is crucial in the rising incidence of hepatic encephalopathy (HE) linked to SPSS. It also increases the risk of portopulmonary hypertension and portal vein thrombosis. Detecting and assessing SPSS rely on computed tomography (CT) and magnetic resonance imaging. CT enables precise measurements and the prediction of cirrhosis progression. Management focuses on liver disease progression and SPSS-related complications, like HE, variceal bleeding, and portopulmonary hypertension. Interventional radiology techniques such as balloon-occluded, plug-assisted, and coil-assisted retrograde transvenous obliteration play a pivotal role. Surgical options are rare but are considered when other methods fail. Liver transplantation (LT) often resolves SPSS. Intraoperative SPSS ligation is still recommended in patients at high risk for developing HE or graft hypoperfusion.

Eosinophilic enteritis: the great mimic.

Eosinophilic enteritis (EoN), a subtype of eosinophilic gastrointestinal disease, is a rare and complicated inflammatory condition affecting the small intestine. This case report discusses a 42-year-old patient who presented with acute gastrointestinal symptoms including diarrhea, nausea, and vomiting. Initial laboratory investigations revealed leukocytosis, peripheral eosinophilia, and distinctive imaging findings, prompting further evaluation. Endoscopic evaluation revealed extensive mucosal lesions in the small intestine, with subsequent biopsies confirming eosinophilic infiltration, ultimately leading to the diagnosis of chronic enteritis, probably of an eosinophilic nature. The case highlights the complex differential diagnostic process involved in identifying EoN, which requires a comprehensive understanding of all the clinical and histopathological features of the disease. The efficacy of budesonide therapy is also discussed in the management of EoN and it was evidenced by our patient's positive response to treatment. This case report contributes significant insights into the understanding and management of EoN, providing essential information for the medical community to facilitate accurate diagnosis and tailored therapeutic interventions for individuals experiencing this complex disorder.
