Case History—A 42 yr old woman presenting with increased bowel frequency, loose stools and urgency after treatment of Campylobacter sp.. Symptoms suggestive of disturbed lower gastrointestinal function without adequate explanation are very common in adults in the Western world, up to 15% of whom experience such symptoms at any one time, although most do not seek medical advice. It is not clear whether the symptoms of those individuals who do seek medical help have a different pathophysiological basis from those who do not, and whether the seeking of medical advice is more an indication of a worried individual than of disturbed gut function....

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.

ABSTRACT Background Irritable bowel syndrome (IBS) and other functional bowel disorders (FBDs) are prevalent disorders with altered microbiota. Prebiotics positively augment gut microbiota and may offer therapeutic potential. Objectives The aim of this study was to investigate the effect of prebiotics compared with placebo on global response, gastrointestinal symptoms, quality of life (QoL), and gut microbiota, via systematic review and meta-analysis of randomized controlled trials (RCTs) in adults with IBS and other FBDs. Methods Studies were identified using electronic databases, back-searching reference lists, and hand-searching abstracts. RCTs that compared prebiotics to placebo in adults with IBS or other FBDs were included. Two reviewers independently performed screening, data extraction, and bias assessment. Outcome data were synthesized as ORs, weighted mean differences (WMDs) or standardized mean differences (SMDs) with the use of a random-effects model. Subanalyses were performed for type of FBD and dose, type, and duration of prebiotic. Results Searches identified 2332 records, and 11 RCTs were eligible (729 patients). The numbers responding were 52/97 (54%) for prebiotic and 59/94 (63%) for placebo, with no difference between groups (OR: 0.62; 95% CI: 0.07, 5.69; P = 0.67). Similarly, no differences were found for severity of abdominal pain, bloating and flatulence, and QoL score between prebiotics and placebo. However, flatulence severity was improved by prebiotics at doses ≤6 g/d (SMD: –0.35; 95% CI: –0.71, 0.00; P = 0.05) and by non-inulin-type fructan prebiotics (SMD: –0.34; 95% CI: –0.66, –0.01; P = 0.04), while inulin-type fructans worsened flatulence (SMD: 0.85; 95% CI: 0.23, 1.47; P = 0.007). Prebiotics increased absolute abundance of bifidobacteria (WMD: 1.16 log10 copies of the 16S ribosomal RNA gene; 95% CI: 0.06, 2.26; P = 0.04). No studies were at low risk of bias across all bias categories. Conclusions Prebiotics do not improve gastrointestinal symptoms or QoL in patients with IBS or other FBDs, but they do increase bifidobacteria. Variations in prebiotic type and dose impacted symptom improvement or exacerbation. This review was registered at PROSPERO as CRD42017074072.

Objective of the Review: To describe and compare some pharmacodynamic and pharmacokinetic parameters of antispasmodic drugs used in complex management of irritable bowel syndrome (IBS) in the Russian Federation. Key Points. IBS is a chronic recurrent disease associated with abdominal pain and bowel disorders. The key factors of IBS pathogenesis include intestinal motility disorders and visceral hypersensitivity. Both processes are controlled by endocrine and neural systems. In a target cell, voltage-operated calcium channels mediate neuronal signals for unstriped muscles to contract and for glands to start secreting. Antispasmodic drugs are a group of products that have been used for IBS management for decades. The review describes contemporary idea of molecular mechanisms to control contraction of GIT muscle cells and a comparison of antispasmodic drugs used in complex therapy of IBS in the Russian Federation. Their key pharmacodynamic and pharmacokinetic characteristics are discussed. Conclusion. The fundamental difference of mebeverine (Duspatalin) is its ability to normalise bowel motility in patients with IBS without the need in complete motility suppression. Also, its inability to block muscarinic receptors and stimulate opioid receptors is another advantage in improving the quality of life of patients. Keywords: pharmacodynamics, pharmacokinetics, antispasmodic drugs, therapy of irritable bowel syndrome, mebeverine.

“Assessment of the physiological effects of physical and emotional stress has been hampered by a lack of suitable laboratory techniques. Since hypnosis can be used safely to induce specific emotional states of considerable intensity, we studied the effect on distal colonic motility of three hypnotically induced emotions (excitement, anger, and happiness) in 18 patients aged 20–48 years with irritable bowel syndrome. Colonic motility index was reduced by hypnosis on its own (mean change 19.1; 95% CI 0.8, 37.3; P < 0.05) and this change was accompanied by decreases in both pulse (12; 8, 15) and respiration (6; 4, 8) rates (P < 0.001 for both). Anger and excitement increased the colonic motility index (50.8; 29.4, 72.2; and 30.4; 8.9, 51.9, respectively; P < 0.01 for both), pulse rate (26; 22, 30; and 28; 24, 32; P < 0.001 for both), and respiration rate (14; 12, 16; and 12; 10, 14; P < 0.001 for both). Happiness further reduced colonic motility although not significantly from that observed during hypnosis alone. Changes in motility were mainly due to alterations in rate than in amplitude of contractions. Our results indicate that hypnosis may help in the investigation of the effects of emotion on physiological functions; this approach could be useful outside the gastrointestinal system. Our observation that hypnosis strikingly reduces fasting colonic motility may partly explain the beneficial effects of this form of therapy in functional bowel disorders.”

The objective of the prospective randomized controlled comparative study to explore about the role of education in the treatment of irritable bowel syndrome (IBS), a chronic continuous or remittent gastrointestinal illness characterized by frequent unexplained symptoms that include abdominal pain, bloating and bowel disturbance. The patients who fulfilled the set criteria of this study and had normal physical examination were considered to undergo screening investigations (Hb%, TC, DC, ESR, blood glucose, serum TSH, stool for R/M/E and short colonoscopy or double contrast barium enema) to exclude any organic disease. In order to administer the same pharmacological treatment only diarrhea predominant patients without any organic disease were recruited for the present study. The number of recruited patients was 80. Of them, 40 patients were given only pharmacological management with Mebeverine Hydrochloride 135 mg thrice daily half an hour before meal and Amitryptyline 10 mg at night for 6 months, and the other 40 patients were given education by a structured and planned educational class for 1 hr in addition to the same pharmacological treatment. In both groups, changes of symptoms and quality of life of the patients were assessed by using a valid IBS related quality of life (IBS-QOL) instrument. The results showed that significant improvement occurred in both the groups of patients at 1 month and 6 months in respect to their baseline IBS-QOL score. But the improvement was not significantly higher in the group with education in comparison to the group without education. Therefore, it can be concluded that the educational class had no extra impact on drug treatment protocol for IBS used in the present study.Mediscope Vol. 2, No. 2: July 2015, Pages 22-27
