Underlying pathophysiological mechanisms of irritable bowel syndrome (IBS), a common disorder characterized by abdominal pain associated to a change in stool consistency or frequency, include low-grade inflammation and intestinal microbiota changes. Few and disappointing data are available for prebiotics. A few controlled trials (RCTs) of probiotics are instead available with favourable effects, although most are limited by suboptimal design and small sample size. A recent report from the Rome foundation group included 32 RCTs of probiotics, most of which showed an overall modest improvement in symptoms, with the patients most benefitting from probiotics being those with predominant diarrhoea and those having a post-infectious IBS. A review focusing only on children with functional gastrointestinal disorders concluded that probiotics are more effective than placebo in the treatment of patients with abdominal pain-related functional gastrointestinal disorders, although no effect on constipation was evident. The role for probiotics in inflammatory bowel disease (IBD) appears logical: the endogenous intestinal microbiota plays a central role in their development, and various probiotics have been found effective in animal models of IBD. However, research in humans has been overall quite limited, and it would seem that after a phase of intense research in the first decade of this century, the pace has slowed down, with fewer clinical trials been published in the past 2-3 years. To summarize current evidence: no probiotic has proven successful in Crohn's disease. In ulcerative colitis, on the other hand, data are more promising, and a very recent meta-analysis, that included 23 randomized controlled trials, concluded that there is evidence of efficacy for the probiotic mixture VSL#3 in helping inducing and maintaining remission, as well as in maintaining remission in patients with pouchitis. It is fair to state that for both IBD and IBS, more well-designed, rigorous, randomized clinical trials must be performed.

Abstract BACKGROUND: The intestinal microbiota is thought to be involved in the occurrence of Inflammatory Bowel Disease in remission (IBDR) with Irritable Bowel Syndrome (IBS)-type symptoms, but the specific distinct profile of these bacteria remains unclear. Therefore, the purpose of this research is to investigate this issue by conducting a cross-sectional study.METHODS: IBS patients were diagnosed according to Rome Ⅳ criteria, IBD diagnosed according to the criteria of European Crohn & Colitis Organization (ECCO), IBDR patients with IBS-type symptoms were defined according to related IBS-type symptoms meeting the Rome IV criteria in IBDR patients, and were included Crohn’s disease in remission (CDR) and ulcerative colitis in remission (UCR) based on Crohn’s Disease Activity Index (DAI) and Mayo Scoring System respectively. Healthy controls come from the physical examination center and exclude people with underlying diseases. All enrolled subjects were divided into six groups, as followed: Health Control, IBS, CDR with IBS-type symptoms (CDR-IBS+), CDR without IBS-type symptoms (CDR-IBS-), UCR-IBS+ and UCR-IBS-. We collected fresh fecal samples from all subjects and applied 16S rRNA sequencing analysis to detect the structure and diversity of the microbiota among different groups. RESULTS: A total of 97 subjects were included in this study, of which 18 were health controls, 34 IBS patients, 25 CDR and 20 UCR. The richness of intestinal microbiota in CDR-IBS-was significantly lower than that in the control and IBS groups based on the analysis of observed species and Chao index (P<0.05). The observed species index in CDR-IBS+ was significantly higher than CDR-IBS- group (median index: 254.8 vs 203, P=0.036). No difference was found in Alpha diversity between UCR-IBS+ and UCR-IBS-. At phylum level, there was no significant difference between UC or CD with IBS-type symptoms and those without related symptoms. At genus level, the number of Faecalibacterium in CDR-IBS+ increased significantly while Fusobacterium decreased compared with CDR-IBS-(mean relative abundance of Faecalibacterium: 20.35% vs 5.18%, P<0.05; Fusobacterium: 1.51% vs 5.2%, P<0.05). However, compared with UCR-IBS - group, the number of Faecalibacterium in UCR-IBS+ group decreased, while the number of Streptococcus increased, but there was no statistical difference in the genus structure. Regardless of the phylum or genus level, the abundance and composition of the microbiota of IBS patients were not distinct from those of healthy people.CONCLUSIONS: CD patients in remission with IBS-type symptoms may be related to the increase of Faecalibacterium and decrease of Fusobacterium. UC patients in remission with IBS-type symptoms cannot be explained by changes in the abundance and structure of intestinal microbiota from our across-sectional study.

The aim of this chapter is to provide nurses with the knowledge to be able to assess, manage, and care for people with the group of conditions often described as functional bowel disorders (FBD)—see definitions below—in an evidence-based and person-centred way. The chapter will provide an overview of the causes and impact of FBDs, before exploring best practice to deliver care, as well as to prevent or to minimize further ill-health. Nursing assessments and priorities are highlighted throughout, and the nursing management of the symptoms and common health problems associated with FBDs can be found in Chapters 16, 23, 24, and 25, respectively. This chapter discusses the group of conditions often described as functional bowel disorders (FBDs). The term ‘functional gastrointestinal disorders’ is also used in the literature, but, for the purpose of this book, the term FBDs will be adopted. This refers to a group of disorders that are characterized by chronic gastrointestinal symptoms that currently have an unknown structural or biochemical cause that could explain those symptoms. Rome III is an internationally agreed set of diagnostic criteria and related information on functional gastrointestinal disorders (Longstreth et al., 2006). It includes six major domains for adults: oesophageal; gastro/duodenal; bowel; functional abdominal pain syndrome; biliary; and anorectal. This chapter will cover the FBDs that specifically relate to chronic abdominal symptoms. General abdominal symptoms include functional dyspepsia, non-cardiac chest pain, which may mimic functional abdominal symptoms, chronic abdominal pain, functional constipation, functional diarrhoea, functional bloating, and irritable bowel syndrome (IBS). The chapter will concentrate on irritable bowel syndrome. Coeliac disease and Crohn’s disease are included: to give an understanding of these disorders, and to differentiate between inflammatory and non-inflammatory conditions; to highlight the impact of the symptoms on the people who suffer from them; and to give an insight into the contribution that effective nursing makes. The amount of research and the number of publications concerning FBDs has risen considerably since the mid 1990s, and has contributed to the increasing legitimacy of these conditions as disorders in their own right and not simply by virtue of exclusion of all other possibilities.

The Impact

Abstract Background Abdominal pain is a frequent symptom in patients with inflammatory bowel disease (IBD) including Crohn’s disease (CD) and ulcerative colitis (UC). Pain can result from ongoing inflammation or functional disorders imitating irritable bowel syndrome (IBS). Several single-nucleotide polymorphisms (SNPs) have been associated with IBS. However, the impact of IBS genetics on the clinical course of IBD, especially pain levels of patients remains unclear. Methods Data of 857 UC and 1206 CD patients from the Swiss IBD Cohort Study were analysed. We tested the association of the maximum of the abdominal pain item of disease activity indices in UC and CD over the study period with 16 IBS-associated SNPs, using multivariate ANOVA models. Results In UC patients, the SNPs rs1042713 (located on the ADRB2 gene) and rs4663866 (close to the HES6 gene) were associated with higher abdominal pain levels (P = 0.044; P = 0.037, respectively). Abdominal pain was not associated with any markers of patient management in a model adjusted for confounders. In CD patients, higher levels of abdominal pain correlated with the number of physician contacts (P < 10–15), examinations (P < 10–12), medical therapies (P = 0.023) and weeks of hospitalisation (P = 0.0013) in a multivariate model. Conclusions We detected an association between maximal abdominal pain in UC patients and two IBS-associated SNPs. Abdominal pain levels had a pronounced impact on diagnostic and therapeutic procedures in CD but not in UC patients.

Abstract Background Rome IV criteria for functional gastrointestinal disorders state that children suspected of having Irritable Bowel Syndrome (IBS) with Constipation (IBS-C) should be preliminarily treated for constipation. We aimed at verifying if functional constipation may indeed lead to an erroneous diagnosis of IBS with diarrhea (IBS-D) or IBS with mixed pattern of diarrhea and constipation (IBS-M).Methods We prospectively enrolled in an unblinded fashion 10 and 16 consecutive children referred to our center who met Rome IV criteria for a diagnosis of IBS-D and IBS-M, respectively. Patients who fulfilled criteria for suspect “occult constipation” were then given a bowel cleaning regimen with PEG 3350, re-evaluated at 2 months and followed up for at least 6 months. Sixteen additional patients with IBS with Constipation (IBS-C) referred in the same period served as control. The endpoints were: 1) a decrease of more than 50% in abdominal pain intensity and frequency scores; and 2) for patients with IBS-D and IBS-M: resolution of diarrhea.Results The endpoints were met by 8 (80%) and 14 (87%) of the patients with IBS-D and IBS-M, respectively, with decrease of abdominal pain and resolution of “diarrhea”. The response was not significantly different from that observed in 15 (93%) of the IBS-C control group.Conclusion acknowledging the limitations of the small number of patients and of the uncontrolled nature of the study, we suggest that a possibly large number of patients labeled as IBS-D or IBS-M may actually simply present functional constipation and should be managed as such.
