BMC Gastroenterology is calling for submissions to our Collection on The gut microbiome: role in liver health and disease. The gut microbiome has emerged as a critical player to maintain liver health and the pathogenesis of liver diseases. The intricate relationship between gut microbiota and liver function, often referred to as the gut-liver axis, highlights how changes in microbiota composition can influence liver metabolism and overall hepatic health. Recent developments in this field have revealed that dysbiosis, or microbial imbalance, may contribute to conditions such as cirrhosis, alcoholic liver disease, metabolic dysfunction-associated steatotic liver disease (MASLD), hepatitis, and even liver cancer, underscoring the importance of understanding this complex interplay.

In addition, recent research shows the implications of gastrointestinal pathogenicity and the exacerbation of severity/outcomes in existing chronic liver disease. Mechanistic studies featuring host susceptibility related to gut microbiome alteration in liver disease can be submitted.

Investigating the role of the gut microbiome in liver health is essential for developing novel therapeutic strategies and interventions. Recent developments have identified specific microbial signatures associated with liver diseases, paving the way for potential diagnostic and prognostic tools. Moreover, interventions such as probiotics and dietary modifications have shown promise in improving liver health outcomes by restoring microbial balance. Future research could unveil novel biomarkers for early detection, elucidate the mechanisms underlying microbial influences on liver pathology, and refine therapeutic strategies targeting the microbiome.

Topics of interest include, but are not limited to:

•The gut-liver axis and liver health

•Interactions between the gut microbiome and liver immunology

•Microbial metabolites and their effects on liver function

•Role of gut microbiota in cirrhosis

•Microbial signatures in viral hepatitis and liver cancer

•Gut microbiota in alcoholic liver disease and MASLD

•Gut-liver axis in autoimmune, cholestatic, hereditary and other rare liver diseases

•Gut microbiome modulation as a therapeutic strategy

•Probiotics and liver disease management

•Environmental impact in gut-liver axis

•The impact of diet on the gut-liver axis

•Fecal transplantation for liver diseases

BMC Gastroenterology is calling for submissions to our Collection on the role of diet in gastrointestinal health.

The relationship between diet and gastrointestinal health has attracted increasing attention in recent years, with emerging evidence highlighting the significant role that nutrition plays in maintaining gut health and preventing digestive disorders. The gut microbiome, a complex ecosystem of microorganisms residing in our intestines, is influenced by dietary patterns and can impact various aspects of gastrointestinal health. Understanding how different foods and dietary habits affect gut microbiota composition and function is essential for developing effective dietary strategies that promote optimal digestive health.

Since gastrointestinal disorders, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and obesity, continue to rise globally, it is important to deepen our understanding of this field. Advances in nutritional science, particularly in understanding the role of prebiotics, probiotics, and fiber, have opened new avenues for improving gut health through dietary interventions. Furthermore, research into the gut-brain axis has opened new avenues for exploring how diet can influence not only physical but also mental well-being. By integrating insights from various disciplines, we can enhance our understanding of the dietary factors that contribute to gastrointestinal health.

Topics of interest include, but are not limited to:

Impact of dietary patterns on gut microbiota

Nutritional interventions for gastrointestinal disorders

Role of fiber and probiotics in digestive health

Eating habits and their effects on intestinal health

Influence of dietary fats on gut health

Effects of plant-based diets on gastrointestinal function

The role of fermented foods in digestive wellness

Impact of sugar and artificial sweeteners on gut microbiota

Dietary approaches to managing gastrointestinal symptoms

The relationship between diet, inflammation, and gastrointestinal diseases
