Special Issue Information

Dear colleagues,

Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disease that represents a significant cause of morbidity worldwide. The disease significantly affects patients’ quality of life, work productivity and social functioning. The pathophysiology of IBS is not completely understood and its diagnosis should be made based on the Rome IV criteria. Nevertheless, the severity of the patient’s symptoms and concerns sometimes drives the physician to perform useless and/or expensive diagnostic tests, transforming IBS into a diagnosis of exclusion. Therefore, a deeper knowledge of IBS mechanisms is mandatory to improve the management of the disease. Conventional treatments include lifestyle changes, diets, probiotics, laxatives, antidiarrhoeals and antispasmodics. More recently, other therapies have been investigated in randomized controlled trials and observational studies, including faecal microbiota transplantation, central neuromodulators, intestinal secretagogues, drugs acting on opioid or 5-HT receptors, minimally absorbed antibiotics, and psychological therapies.

The scientific community will certainly benefit from updated reviews focusing on the optimal management of IBS. In this Special Issue, we invite you to submit your updated review addressing the management aspects and/or therapeutics of IBS.

We look forward to your contribution relating to this cutting-edge Special Issue of the Journal of Clinical Medicine.

Irritable bowel syndrome (IBS) is a highly prevalent and debilitating disorder of gut–brain interaction (DGBI) affecting millions globally. It imposes a significant burden on healthcare systems and is a leading cause of workplace absenteeism. IBS is classified into several subtypes based on predominant presenting symptoms, including IBS with constipation (IBS-C) and IBS with diarrhea (IBS-D), with each requiring targeted approaches to treatment. Some treatments, such as psychotherapy, dietary intervention, and medications like tricyclic antidepressants, are nonspecific and recommended for managing IBS symptoms across all subtypes. In contrast, therapies like secretagogues for IBS-C and eluxadoline or rifaximin for IBS-D are subtype-specific. However, many IBS treatments carry conditional recommendations and are based on low-certainty evidence, emphasizing the need for further research to expand the available treatment options. This review compares the latest IBS management guidelines from the American Gastroenterological Association (AGA), American College of Gastroenterology (ACG), British Society of Gastroenterology (BSG), and European Society for Neurogastroenterology and Motility (ESNM). Pharmacologic and non-pharmacologic therapies, including established and emerging interventions, will be explored to provide a comprehensive guide to management. Full article

Globally, irritable bowel syndrome (IBS) is present in approximately 10% of the population. While this condition does not pose a risk of complications, it has a substantial impact on the patient’s quality of life. Moreover, this disease has a significant financial impact on healthcare systems. This includes the direct costs associated with the diagnosis and treatment of these patients, as well as the indirect costs that arise from work absenteeism and reduced productivity. In light of these data, recent research has focused on elucidating the pathophysiological basis of this condition in order to improve the quality of life for affected individuals. Despite extensive research to date, we still do not fully understand the precise mechanisms underlying IBS. Numerous studies have demonstrated the involvement of the gut–brain axis, visceral hypersensitivity, gastrointestinal dysmotility, gut microbiota dysbiosis, food allergies and intolerances, low-grade mucosal inflammation, genetic factors, and psychosocial factors. The acquisition of new data is crucial for the advancement of optimal therapeutic approaches aimed at enhancing the general health of these patients while simultaneously reducing the financial burden associated with this ailment.
