Background: Persistent gastrointestinal symptoms are prevalent in adult patients with inflammatory bowel disease (IBD), even when endoscopic remission is reached. These symptoms can have profound negative effects on the quality of life of affected patients and can be difficult to treat. They may be caused by IBD-related complications or comorbid disorders, but they can also be explained by irritable bowel syndrome (IBS)-like symptoms., Aims: To provide a practical step-by-step guide to diagnose and treat persistent gastrointestinal symptoms in patients with IBD in remission via a personalised approach., Methods: We scrutinised relevant literature on causes, diagnostics and treatment of persistent gastrointestinal symptoms (abdominal pain or discomfort, bloating, abdominal distension, diarrhoea, constipation and faecal incontinence) in patients with IBD in remission., Results: A graphical practical guide for several steps in diagnosing, identifying potential triggers and adequate treatment of persistent gastrointestinal symptoms in IBD in remission is provided based on supporting literature. The first part of this review focuses on the diagnostic and treatment approaches for potential IBD-related complications and comorbidities. The second part describes the approach to IBS-like symptoms in IBD in remission., Conclusions: Persistent gastrointestinal symptoms in IBD in remission can be traced back to potential pathophysiological mechanisms in individual patients and can be treated adequately. For both IBD-related complications and comorbidities and IBS-like symptoms in IBD in remission, pharmacological, dietary, lifestyle or psychological treatments can be effective. A systematic and personalised approach is required to reduce the burden for patients, healthcare systems, and society., (© 2024 The Authors.

Introduction: This study focused on defining the global prevalence of clinically relevant levels of psychological distress and somatic symptoms and the prevalence of coexistence between these symptoms and disorders of gut-brain interaction (DGBI). We also analyzed how clinically relevant psychological distress and somatic symptoms and coexistent DGBI are associated with health-related outcomes., Methods: We included a representative sample of 54,127 adult participants (49.1% women; mean age of 44.3 years) from 26 countries worldwide. Participants completed an Internet survey (the Rome Foundation Global Epidemiology Study) with validated self-report questionnaires., Results: Clinically relevant psychological distress and/or somatic symptom severity was reported by 37.5% of the sample. These participants had 4.45 times higher odds to have at least one DGBI than individuals without psychological distress and/or somatic symptoms. Compared with participants with psychological distress and/or somatic symptoms with vs without DGBI, participants with a DGBI reported increased healthcare and medication utilization (with OR from 1.6 to 2.8). Coexistent DGBI in participants with psychological distress and/or somatic symptoms was the variable most strongly associated with reduced mental (β = -0.77; confidence interval [-0.86 to -0.68]) and physical (β = -1.17; confidence interval [-1.24 to -1.10]) quality of life., Discussion: This global study shows that psychological distress, somatic symptoms, and DGBI are very common and frequently overlap. The coexistence between psychological distress/somatic symptoms and DGBI seems to be especially detrimental to quality of life and healthcare utilization. Individuals with psychological distress/somatic symptoms and DGBI coexistence seem to be a group vulnerable to psychosocial problems that should be studied further and would likely benefit from psychological/psychiatric interventions., (Copyright © 2023 by The American College of Gastroenterology.)

Background: Previous epidemiologic studies in Sweden have only covered some of the disorders of gut-brain interaction (DGBI) and are not representative of the general population. This study aimed to define the prevalence and impact of DGBI in Sweden., Methods: We used Swedish data from the Rome Foundation Global Epidemiology Study which include information on DGBI diagnoses, psychological distress, quality of life (QoL), healthcare utilization, and the impact of stress on GI symptoms., Key Results: The prevalence of having any DGBI was 39.1% (95% CI 37.0-41.2); esophageal disorders 6.1% (5.1-7.3), gastroduodenal disorders 10.7% (9.3-12.0), bowel disorders 31.6% (29.6-33.6), and anorectal disorders 6.0% (5.1-7.2). Subjects with a DGBI more commonly reported anxiety and/or depression, reduced mental and physical QoL, and more frequent doctor visits due to health problems. Subjects with a DGBI reported bothersome gastrointestinal (GI) symptoms to a greater extent and more than 1/3 had visited a doctor due to GI problems and of those 1/3 had seen multiple doctors. Prescription medications were available among 36.4% (31.0-42.0) who had bothersome GI symptoms and a DGBI, with sufficient symptom relief in 73.2% (64.0-81.1). Psychological factors and eating were reported to worsen GI symptoms and stress during the last month was greater in subjects with a DGBI., Conclusions and Inferences: DGBI prevalence and its impact in Sweden is in line with global data, including increased healthcare utilization. GI symptoms are commonly affected by psychological factors and eating, and a high proportion of those on prescription medication report sufficient GI symptom relief., (© 2023 The Authors.

Gastroesophageal reflux disease (GERD) often requires lifelong treatment to return to and maintain a normal quality of life. Proton pump inhibitors (PPIs) offer effective medical treatment and can be used for a long time with good safety margins. The diagnostic criteria for GERD must be strictly based on current guidelines and the need for maintained treatment must be regularly evaluated. When medical treatment fails (> 20%), the patient should be offered a consultation with a specialist in the field. Too many patients who are currently treated with PPI for suspected GERD ultimately require treatment with a completely different diagnosis in focus. The investigation and treatment options are several and well-defined in the event of PPI failure in patients with well documented GERD. The indications for surgical treatment are well established, but this treatment option is likely underused today.

Background & Aims: Little is known about the population prevalence or demographic distributions of Rome IV functional bowel disorders (FBDs) or their effects on quality of life. We examined these in a multinational survey., Methods: We analyzed data from a population-based survey of adults in the United States, Canada, and United Kingdom (5931 valid responders; 49.2% female; mean age, 47.4 years; range, 18-92 years). The survey included the Rome IV Diagnostic Questionnaire, Rome III irritable bowel syndrome (IBS) and constipation questions, and the SF-8 quality of life questionnaire., Results: The prevalence values of census-adjusted Rome IV FBDs were similar among the 3 countries; ranges were: 4.4%-4.8% for IBS, 7.9%-8.6% for functional constipation, 3.6%-5.3% for functional diarrhea, 2.0%-3.9% for functional bloating or distention, 1.1%-1.9% for opioid-induced constipation, 7.5%-10.0% for unspecified FBDs, and 28.6%-31.7% for any Rome IV FBD. FBDs were less common in older individuals, and all except functional diarrhea were more common in women. IBS was only half as prevalent by Rome IV as by Rome III criteria (4.6% vs 9.0% overall), primarily due to higher Rome IV minimum pain frequency. Functional diarrhea and functional constipation were more prevalent by Rome IV than Rome III criteria. Subjects with FBD had significant reductions in quality of life and reported more gastrointestinal doctor consultations than other subjects., Conclusions: More than 1 in 4 adults in the general population meet the Rome IV criteria for FBDs. These disorders affect quality of life and increase use of gastrointestinal health care. The switch from Rome III to Rome IV criteria reduces the prevalence of IBS by half, but increases the prevalence of functional constipation and functional diarrhea., (Copyright © 2020 AGA Institute.

Background & Aims: There are few data from longitudinal studies of the gastrointestinal and psychologic features of irritable bowel syndrome (IBS). We studied within-person correlations among features of IBS, along with progression of gastrointestinal (GI) symptoms and quality of life, and factors associated with changes over time., Methods: We performed a longitudinal study of 276 patients with IBS in Sweden (70% female; ages, 19-76 years) who completed questionnaires, each year for 5 years, about their GI symptom severity, quality of life, GI-specific anxiety, general anxiety, depression, and coping resources. We performed within-person correlation analyses, latent class growth analysis, and random-intercept cross-lagged panel analysis., Results: Within-person correlations with GI symptom severity were strongest for quality of life (r = -0.56) and GI-specific anxiety (r = 0.47). Progression of GI symptom severity was defined based on 3 classes; the class with the highest mean levels of GI, depression, and (GI-specific) anxiety symptoms at baseline did not improve over the 5-year period, contrary to the other classes. GI-specific anxiety was associated with an increase in GI symptom severity and decrease in quality of life 1 year later (P < .05) but other features of IBS were not., Conclusions: In a 5-year study of patients with IBS in Sweden, we found 3 classes of GI symptom development. We found levels of GI-specific anxiety to associate with GI symptom severity and quality of life 1 year later. Clinicians should be aware of GI-specific anxiety in patients with IBS, to identify patients at risk for lack of long-term symptom improvement with standard medical treatment., (Copyright © 2018 AGA Institute.

Objectives: The population prevalence of Rome IV-diagnosed functional gastrointestinal disorders (FGIDs) and their cumulative effect on health impairment is unknown., Methods: An internet-based cross-sectional health survey was completed by 5,931 of 6,300 general population adults from three English-speaking countries (2100 each from USA, Canada, and UK). Quota-based sampling was used to generate demographically balanced and population representative samples with regards to age, sex, and education level. The survey enquired for demographics, medication, surgical history, somatization, quality of life (QOL), doctor-diagnosed organic GI disease, and criteria for the Rome IV FGIDs. Comparisons were made between those with Rome IV-diagnosed FGIDs against non-GI (healthy) and organic GI disease controls., Results: The number of subjects having symptoms compatible with a FGID was 2,083 (35%) compared with 3,421 (57.7%) non-GI and 427 (7.2%) organic GI disease controls. The most frequently met diagnostic criteria for FGIDs was bowel disorders (n=1,665, 28.1%), followed by gastroduodenal (n=627, 10.6%), anorectal (n=440, 7.4%), esophageal (n=414, 7%), and gallbladder disorders (n=10, 0.2%). On average, the 2,083 individuals who met FGID criteria qualified for 1.5 FGID diagnoses, and 742 of them (36%) qualified for FGID diagnoses in more than one anatomic region. The presence of FGIDs in multiple regions was associated with increasing somatization, worse mental/physical QOL, more medical therapies, and a higher prevalence of abdominal surgeries; all P<0.001. Notably, individuals with FGIDs in multiple regions had greater somatization and worse QOL than organic GI disease controls., Conclusions: Roughly a third of the general adult population fulfils diagnostic criteria for a Rome IV FGID. In a third of this subset multiple GI regions are involved and this overlap is associated with increased health impairment.

Objectives: Despite the fact that food and diet are central issues, that concern patients with irritable bowel syndrome (IBS), the current understanding about the association between the intake of certain foods/food groups and the gastrointestinal (GI) symptom pattern, psychological symptoms, and quality of life is poor. The aim of this study was to determine which food groups and specific food items IBS patients report causing GI symptoms, and to investigate the association with GI and psychological symptoms and quality of life., Methods: We included 197 IBS patients (mean age 35 (18-72) years; 142 female subjects) who completed a food questionnaire in which they specified symptoms from 56 different food items or food groups relevant to food intolerance/allergy. The patients also completed questionnaires to assess depression and general anxiety (Hospital Anxiety and Depression), GI-specific anxiety (Visceral Sensitivity Index), IBS symptoms (IBS-Severity Scoring System), somatic symptoms (Patient Health Questionnaire-15), and quality of life (Irritable Bowel Syndrome Quality of Life Questionnaire)., Results: In all, 84% of the studied population reported symptoms related to at least one of the food items surveyed. Symptoms related to intake of food items with incompletely absorbed carbohydrates were noted in 138 (70%) patients; the most common were dairy products (49%), beans/lentils (36%), apple (28%), flour (24%), and plum (23%). Of these, 58% experienced GI symptoms from foods rich in biogenic amines, such as wine/beer (31%), salami (22%), and cheese (20%). Histamine-releasing foods, such as milk (43%), wine/beer (31%), and pork (21%), were also considered causes of symptoms in IBS patients. GI symptoms were also frequently reported after intake of fried and fatty foods (52%). With increasing IBS symptom severity, patients reported more food items responsible for their GI symptoms (P=0.004), and this was also found in patients with more severe somatic symptoms (P<0.0001). Women tended to report more food items causing symptoms than men (P=0.06). A high number of food items causing GI symptoms was also associated with reduced quality of life and this was significant for the following domains: sleep (r=-0.25; P=0.001), energy (r=-0.21; P=0.005), food (r=-0.29; P<0.001), social functioning (r=-0.23; P=0.001), and physical status (r=-0.16; P<0.05). However, the number of food items reported to provoke GI symptoms was unrelated to body mass index, age, IBS subtype, anxiety, depression, or GI-specific anxiety., Conclusions: The majority of IBS patients believe that certain food items are important triggers of their GI symptoms. This is especially true for foods containing carbohydrates and fat, and also may be relevant for histamine-releasing food items and foods rich in biogenic amines. Self-reported food intolerance is associated with high symptom burden and reduced quality of life.

ABSTRACT Background Aims Methods Results Conclusions Abdominal pain can be an overlooked symptom in patients with ulcerative colitis (UC).The aim of this study was to investigate the prevalence and factors associated with abdominal pain in active and quiescent UC.Three study cohorts of adult UC patients were used. Cross‐sectional cohorts I and II included 130 (46 active) and 288 (156 active) patients. Longitudinal cohort III included 83 patients with active disease at diagnosis that reached deep remission during follow‐up. The Gastrointestinal Symptom Rating Scale was used to assess abdominal pain and other validated questionnaires to assess psychological distress, fatigue and quality of life (QoL).In the two cross‐sectional cohorts, 63% and 58% of the active vs. 54% and 33% of the quiescent UC patients reported abdominal pain (both p ≤ 0.02). In the longitudinal cohort, 71% had abdominal pain at diagnosis vs. 46% when in remission (p < 0.001). In multivariable models, symptoms of anxiety were associated with higher abdominal pain levels in both cross‐sectional cohorts (OR 1.75 [IQR 1.11–2.76] and OR 1.99 [1.45–2.73]), whereas in cohort II, active disease (OR 2.68 [1.61–4.45]) and female sex (OR 2.03 [1.21–3.41]) were also associated with pain. QoL was negatively correlated with higher levels of abdominal pain, both in active and quiescent disease.Abdominal pain in UC is prevalent and associated with lower QoL in both active and quiescent disease. Associated factors are active disease, female sex and psychological symptoms, especially anxiety. We suggest considering a holistic approach when treating UC patients with abdominal pain.

Background: Visceral hypersensitivity in irritable bowel syndrome (IBS), measured with rectal balloon distensions, using a barostat, has been suggested to be a phenomenon that is reduced due to habituation at repeated investigations. We investigated the stability of rectal sensitivity in patients with IBS who had undergone a previous rectal barostat study and assessed variations in symptom pattern and severity in relation to rectal sensory function. Method: Irritable bowel syndrome patients, who had previously been undergone a rectal barostat study, were included. All patients underwent a second study 8‐12 years later. Symptoms were characterized by use of questionnaires. Key Results: We included 26 subjects (17 females, median age at the index investigation 44.5 (21‐61) years). Pressure and volume sensory thresholds were unchanged at the follow‐up compared with the index investigation (P > 0.05 for all). At the index investigation, 8/26 patients had rectal hypersensitivity of which four were reclassified as normosensitive, and sixfrom normo‐ to hypersensitive, meaning that 10/26 patients were hypersensitive at the follow‐up investigation. IBS‐QOL had improved significantly in six of nine domains at follow‐up (P < 0.05 for all). There were no differences in anxiety, depression, IBS symptom severity, or somatization (P > 0.05) at follow‐up. None of these were associated with change in rectal sensitivity at follow‐up. Conclusions and Inferences: Rectal hypersensitivity and IBS symptoms remained stable at the group level over 8‐12 years in IBS patients, even though individual fluctuations were noted. Our findings contradict previous findings indicating that visceral hypersensitivity is an unstable trait. [ABSTRACT FROM AUTHOR]

Background: Irritable Bowel Syndrome (IBS) negatively influences mental and physical quality of life (QoL), but factors that explain this impact are still unclear. Increasing evidence has associated IBS severity, psychological distress, somatic symptoms, and gastrointestinal (GI)-specific anxiety with QoL in IBS. The aim of this study is to further explore these associations and to analyze potential mediating factors.Method: A total of 1017 IBS patients (69.3% female, mean age 40.6 years) who completed a QoL measure (SF-36) were included in this study. A proportion of these participants (N = 183; 72.7% female, mean age 41.7), who additionally completed psychological distress, somatic symptoms, and GI-specific anxiety measures, was included in the mediation analysis. This analysis was conducted via structural equation modelling to identify factors of importance for generic QoL, using a cross-sectional design.Results: IBS patients reported lower QoL than what is observed in the general population, in particular regarding role limitations caused by health and emotional functioning, vitality, and social functioning. Female patients scored lower than male patients on most QoL dimensions. The effects of IBS severity on mental and physical QoL were mediated by GI-specific anxiety. In addition to GI-specific anxiety, depressive symptoms were also of importance for mental QoL, and somatic symptom severity for physical QoL.Conclusion: QoL is reduced in patients with IBS and GI-specific anxiety, depressive symptoms, and somatic complaints are particularly important for this outcome. Future trials should test the efficacy of psychological interventions specifically targeting these factors in improving QoL in IBS. [ABSTRACT FROM AUTHOR]
