Diet and Microbiota Modulation for Chronic Pouchitis: Evidence, Challenges, and Opportunities.

Chronic pouchitis occurs in about 50% of patients undergoing a restorative proctocolectomy for ulcerative colitis. This affection represents a significant therapeutic challenge, particularly for symptomatic patients who do not respond to antibiotic treatments and biologic therapies. Several dietary approaches, including low FODMAP diets and the Mediterranean diet, have shown promising results in improving symptoms and disease burden.

"Pleiotropic" Effects of Antibiotics: New Modulators in Human Diseases.

Antibiotics, widely used medications that have significantly increased life expectancy, possess a broad range of effects beyond their primary antibacterial activity. While some are recognized as adverse events, others have demonstrated unexpected benefits. These adjunctive effects, which have been defined as "pleiotropic" in the case of other pharmacological classes, include immunomodulatory properties and the modulation of the microbiota.

International consensus statement on microbiome testing in clinical practice.

There is growing interest in the potential exploitation of the gut microbiome as a diagnostic tool in medicine, but evidence supporting its clinical usefulness is scarce. An increasing number of commercial providers offer direct-to-consumer microbiome diagnostic tests without any consensus on their regulation or any proven value in clinical practice, which could result in considerable waste of individual and health-care resources and potential drawbacks in the clinical management of patients. We convened an international multidisciplinary expert panel to standardise best practices of microbiome testing for clinical implementation, including recommendations on general principles and minimum requirements for their provision, indications, pre-testing protocols, method of analyses, reporting of results, and potential clinical value.

The role of microbiome in the development of gluten-related disorders.

Gluten-related disorders (GRD) include celiac disease (CD), non celiac gluten sensitivity (NCGS) and wheat allergy (WA), conditions that are associated with the ingestion of gluten-containing food. Gut microbiota composition and function may be involved in the pathogenesis of GRD. In untreated CD the microbiota is characterized by a reduction in beneficial microbes like Lactobacillus and Bifidobacterium and an increase in pathogenic ones such as Bacteroides and E.

Gut microbiota in inflammation and colorectal cancer: A potential Toolbox for Clinicians.

Colorectal cancer (CRC) is a worldwide public health issue specifically in patients with chronic diseases associated with a western lifestyle, such as metabolic diseases and inflammatory bowel diseases (IBD). Interestingly, both metabolic disorders and IBD are characterized by a chronic state of inflammation that contributes to the carcinogenesis with specific alteration of the gut microbiota composition and function. Evidence now shows that this altered gut microbiota contributes fueling a chronic pro-inflammatory state in a vicious circle that can favor CRC development.

Gut microbiome and metabolic dysfunction-associated steatotic liver disease: Pathogenic role and potential for therapeutics.

Gut microbiota plays key functions in the human body, and its alteration is associated with several human disorders. Moreover, its manipulation is being investigated as a potential therapeutic strategy. In this narrative review we will dissect the involvement of the gut microbiota and of the gut-liver axis on metabolic dysfunction-associated steatotic liver disease (MASLD).

The microbiome-driven impact of western diet in the development of noncommunicable chronic disorders.

Noncommunicable chronic disorders (NCDs) are multifactorial disorders that share a state of chronic, low-grade inflammation together with an imbalance of gut microbiota. NCDs are becoming increasingly prevalent worldwide, and mainly in Western countries, with a significant impact on global health. Societal changes, together with the widespread diffusion of modern agricultural methods and food processing, have led to a significant shift in dietary habits over the past century, with an increased diffusion of the Western diet (WD).

Review Article: Green Management of IBD-New Paradigms for an Eco-Friendly Approach.

Background: The worldwide prevalence of inflammatory bowel disease (IBD) is increasing, with its potential evolution as a global disease and a consequent increase in its burden on healthcare systems. These estimates do not factor in the 'real' price of IBD, which, beyond curbing career aspirations, instilling social stigma, and impairing the quality of life in patients, could also significantly affect the environment.

Aim: To highlight potential areas for intervention and develop management strategies aimed at minimising environmental impacts in the field of IBD over time.

Endoscopic Management of Strictures in Crohn's Disease: An Unsolved Case.

Crohn's disease (CD) is a chronic inflammatory disease associated with a significant burden in terms of quality of life and health care costs. It is frequently associated with several complications, including the development of intestinal strictures. Stricturing CD requires a careful multidisciplinary approach involving medical therapy and surgery, still posing a continuous management challenge; in this context, endoscopic treatment represents a valuable, in-between opportunity as a minimally invasive strategy endorsed by extensive yet heterogeneous evidence and evolving research and techniques.

and the Human Gastrointestinal Microbiota: A Multifaceted Relationship.

is a type of Gram-negative bacteria belonging to the Proteobacteria phylum which is known to cause gastrointestinal disorders such as gastritis and gastric ulcers. Its treatment is based on current eradication regimens, which are composed of combinations of antibiotics such as clarithromycin, metronidazole, levofloxacin and amoxicillin, often combined with a proton pump inhibitor (PPI). With the development of sequencing technologies, it has been demonstrated that not only does the colonization of the gastric and gut environment by cause microbial changes, but also the treatment regimens used for its eradication have a significant altering effect on both the gastric and gut microbiota.

Prevalence of irritable bowel syndrome and functional dyspepsia after acute gastroenteritis: systematic review and meta-analysis.

Objective: Disorders of gut-brain interaction may arise after acute gastroenteritis. Data on the influence of pathogen type on the risk of postinfection IBS (PI-IBS), as on postinfection functional dyspepsia (PI-FD), are limited. We conducted a systematic review and meta-analysis to determine prevalence of PI-IBS or PI-FD after acute gastroenteritis.

Fecal microbiota transplantation: current challenges and future landscapes.

SUMMARYGiven the importance of gut microbial homeostasis in maintaining health, there has been considerable interest in developing innovative therapeutic strategies for restoring gut microbiota. One such approach, fecal microbiota transplantation (FMT), is the main "whole gut microbiome replacement" strategy and has been integrated into clinical practice guidelines for treating recurrent infection (rCDI). Furthermore, the potential application of FMT in other indications such as inflammatory bowel disease (IBD), metabolic syndrome, and solid tumor malignancies is an area of intense interest and active research.

Donor screening for fecal microbiota transplantation with a direct stool testing-based strategy: a prospective cohort study.

Fecal microbiota transplantation (FMT) is effective against recurrent Clostridioides difficile infection (rCDI), but its safety is jeopardized by the potential transmission of pathogens, so international guidelines recommend either a quarantine or a direct stool testing. Whereas reports of the quarantine-based approach are emerging, data on the direct testing-based approach are not available. Our aim is to report outcomes of a donor screening framework for FMT including direct stool testing.

Fine-tuning the gut ecosystem: the current landscape and outlook of artificial microbiome therapeutics.

The gut microbiome is acknowledged as a key determinant of human health, and technological progress in the past two decades has enabled the deciphering of its composition and functions and its role in human disorders. Therefore, manipulation of the gut microbiome has emerged as a promising therapeutic option for communicable and non-communicable disorders. Full exploitation of current therapeutic microbiome modulators (including probiotics, prebiotics, and faecal microbiota transplantation) is hindered by several factors, including poor precision, regulatory and safety issues, and the impossibility of providing reproducible and targeted treatments.

Probiotic mixture in patients after Helicobacter pylori eradication: a real-life experience.

Background: Eradication for Helicobacter pylori usually induces digestive dysbiosis that, in turn, elicits symptoms. Consequently, probiotic supplementation may counterbalance the disturbed microbiota after this procedure. So, probiotics may restore microbiota homeostasis quickly relieve complaints.

Micro(nano)plastics and Their Potential Impact on Human Gut Health: A Narrative Review.

Microplastics and nanoplastics (MNPs) are becoming an increasingly severe global problem due to their widespread distribution and complex impact on living organisms. Apart from their environmental impact, the effects of MNPs on living organisms have also continued to attract attention. The harmful impact of MNPs has been extensively documented in marine invertebrates and larger marine vertebrates like fish.

Fecal Microbiota Transplantation in Amyotrophic Lateral Sclerosis: Clinical Protocol and Evaluation of Microbiota Immunity Axis.

The fecal microbial transplantation (FMT) is a therapeutic transplant of fecal microbiota from healthy donors to patients. This practice is aimed at restoring eubiosis and rebalancing the enteric and systemic immune responses, and then eliminating pathogenic triggers of multiple disease, including neurodegenerative diseases. Alterations of gut microbiota (GM) affect the central nervous system (CNS) health, impacting neuro-immune interactions, synaptic plasticity, myelination, and skeletal muscle function.

The Role of Diet and Nutritional Interventions for the Infant Gut Microbiome.

The infant gut microbiome plays a key role in the healthy development of the human organism and appears to be influenced by dietary practices through multiple pathways. First, maternal diet during pregnancy and infant nutrition significantly influence the infant gut microbiota. Moreover, breastfeeding fosters the proliferation of beneficial bacteria, while formula feeding increases microbial diversity.
