- Background: Aloe barbadensis Mill. (Aloe) extract was found to be well-tolerated, safe and showed beneficial effects in subsets of irritable bowel syndrome (IBS) patients in two randomized, double-blind, controlled studies. However, the individual studies were underpowered to perform subgroup analyses. We therefore determined the effect of Aloe extract in IBS subgroups in a post hoc analysis combining the results from the two studies. Methods: Data from the two controlled studies comparing Aloe and control treatment taken orally for 4 weeks, were pooled. Both studies included IBS patients fulfilling the ROME III criteria and IBS Symptom Severity Score (IBS-SSS) was assessed. We analysed the effect of Aloe extract on IBS symptom severity and the proportion of responders (IBS-SSS reduction > 50) in IBS subgroups. Results: In total, 213 IBS patients were included in the post hoc subgroup analyses. A reduction in overall symptom severity, primarily driven by effect on pain severity and frequency, comparing baseline versus end of treatment, was recorded in IBS patients with diarrhoea (IBS-D) receiving Aloe (n = 38, p < 0.001) but not control treatment (n = 33, p = 0.33), with difference between the treatment groups (p = 0.01). Moreover, the frequency of responders was higher in IBS-D patients receiving Aloe (n = 22, 58%) compared to control treatment (n = 10, 30%) (p = 0.02). The effect of Aloe extract treatment on IBS symptom severity was not superior to control treatment in the other IBS subtypes. Conclusion: Aloe extract improves symptom severity in IBS-D patients and can be regarded as a safe and effective treatment option for this patient group.

Journal article (peer-reviewed)abstract
- Background Aloe barbadensis Mill.(Aloe) with potential prebiotic effects has been suggested to reduce symptoms in patients with irritable bowel syndrome (IBS). We therefore aimed to determine the effects of an Aloe extract on symptoms of IBS, and evaluate whether effects may be mediated by fecal microbiota and metabolites in a randomized, double-blind, controlled trial. Methods Patient with IBS diagnosed according to the ROME III criteria (all subtypes), received Aloe or control treatment (inulin) for 4 weeks. IBS Symptom Severity Score (IBS-SSS) was assessed, and fecal samples collected before and at end of treatment. Fecal microbiota composition and metabolomic profile were determined. Key results In total, 160 IBS patients completed the study. The overall severity of IBS symptoms was reduced in both Aloe and control treatment groups (P < .001, both groups, comparing baseline vs end of treatment), without difference between groups (P = .62). The frequency of responders (IBS-SSS reduction >= 50) did not differ between Aloe treatment (n = 33, 39%) and control (n = 34, 45%) (P = .49). However, fecal microbiota and metabolite profiles differed between Aloe, but not control treatment responders and non-responders both before and after treatment. Conclusion In a mixed group of IBS patients, Aloe was not superior to control treatment, although it showed potential to reduce IBS symptom severity in subsets of IBS patients which could be predicted by fecal microbiota and metabolite profiles.

Journal article (peer-reviewed)abstract
- Background A gluten-free diet reduces symptoms in some patients with irritable bowel syndrome (IBS) through unclear mechanisms. Aims To assess the effects of gluten-free versus gluten-containing diet on symptoms and the gut microenvironment, and to identify predictors of response to the gluten-free diet in IBS. Methods Twenty patients with IBS and 18 healthy controls (HC) followed a gluten-free diet during two 14-day intervention periods where they sprinkled either gluten (14 g/day) or rice flour powder over their meals. Primary outcomes included effects of the interventions on IBS symptoms (IBS-SSS) and bowel habits. Secondary outcomes included effects of gluten-free diet on faecal microbiota and metabolite profile. Results IBS symptoms improved during the gluten-free (p = 0.02), but not the gluten-containing period, with no difference between the interventions. IBS patients reported fewer loose stools during the gluten-free intervention (p = 0.01). Patients with IBS and HC presented distinct metabolite profiles based on the effects of the gluten-free diet (p < 0.001). True responders (reduced IBS-SSS by >= 50 solely after gluten-free period) and non-responders were discriminated based on the effects of the gluten-free diet on the microbiota (p < 0.01) and metabolite profiles (p < 0.001). The response to the gluten-free diet could be predicted by the metabolite profile before the intervention (p < 0.001). Conclusions A gluten-free diet may influence symptoms in a subset of patients with IBS, with a particular effect on bowel habits. A gluten-free diet seems to impact the gut microenvironment. Responsiveness to the gluten-free diet may be predicted by the metabolite profile. : NCT03869359.

Meditation over medication for irritable bowel syndrome? On exercise and alternative treatments for irritable bowel syndrome.

Research review (peer-reviewed)abstract
- Complimentary alternative treatment regimens are widely used in irritable bowel syndrome (IBS), but the evidence supporting their use varies. For psychological treatment options, such as cognitive behavioral therapy, mindfulness, gut-directed hypnotherapy, and psychodynamic therapy, the evidence supporting their use in IBS patients is strong, but the availability limits their use in clinical practice. Dietary interventions are commonly included in the management of IBS patients, but these are primarily based on studies assessing physiological function in relation to dietary components, and to a lesser degree upon research examining the role of dietary components in the therapeutic management of IBS. Several probiotic products improve a range of symptoms in IBS patients. Physical activity is of benefit for health in general and recent data implicates its usefulness also for IBS patients. Acupuncture does not seem to have an effect beyond placebo in IBS. A beneficial effect of some herbal treatments has been reported.

Journal article (peer-reviewed)abstract
- A diet with reduced content of fermentable short-chain carbohydrates (fermentable oligo-, di-, monosaccharides, and polyols [FODMAPs]) has been reported to be effective in the treatment of patients with irritable bowel syndrome (IBS). However, there is no evidence of its superiority to traditional dietary advice for these patients. We compared the effects of a diet low in FODMAPs with traditional dietary advice in a randomized controlled trial of patients with IBS.

Nutrient intake in patients with irritable bowel syndrome compared with the general population. : Nutrient intake in IBS
- 2013
-
In: Neurogastroenterology and motility : the official journal of the European Gastrointestinal Motility Society. - : Wiley. - 1365-2982. ; 25:1
-
Journal article (peer-reviewed)abstract
- Background Food and diet are central issues that concern patients with irritable bowel syndrome (IBS). Few studies have thoroughly analyzed dietary intake in IBS. Our aims were to determine the nutrient intake in IBS patients in comparison to the general population, assess nutritional differences between IBS subgroups based on the predominant bowel habit or symptom severity, as well as to evaluate if their nutrient intake meet nutrition recommendations. Methods We included 187 IBS patients (mean 40.2years; 139 women). They completed a 4-days food registration record, which was compared with an age-, and gender-matched control group (n=374; 278 women) from a nation-wide dietary survey and with Nordic Nutrient Recommendations. Key Results Daily nutrient intake in IBS patients was similar to the general population and met national nutrients recommendations. Irritable bowel syndrome patients had similar energy distribution from macronutrients compared to the control group, but the protein percentage tended to be higher. Irritable bowel syndrome patients also had significantly higher daily intake of vitamin E, folate, iron, vitamin C, and dietary fibers, as well as lower intake of vitamin A, riboflavin, calcium, and potassium. There was no association between nutrient intake and IBS subtypes or symptom severity. Conclusions & Inferences Although many IBS patients state that they avoid food items, this does not seem to influence their intake of nutrients to any large extent. The observed minor differences in nutrient intake indicate a tendency toward higher intake of fruit and vegetables and a lower intake of meat and dairy products in IBS patients.

Self-Reported Food-Related Gastrointestinal Symptoms in IBS Are Common and Associated With More Severe Symptoms and Reduced Quality of Life
- 2013
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270. ; 108:5, s. 634-641
-
Journal article (peer-reviewed)abstract
- 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.

A Small Particle Size Diet Reduces Upper Gastrointestinal Symptoms in Patients With Diabetic Gastroparesis: A Randomized Controlled Trial
- 2014
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270. ; 109:3, s. 375-385
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: Gastroparesis is a well-known complication to diabetes mellitus (DM). Dietary advice is considered to be of importance to reduce gastrointestinal (GI) symptoms in patients with diabetic gastroparesis, but no randomized controlled trials exist. Our aim was to compare GI symptoms in insulin treated DM subjects with gastroparesis eating a diet with small particle size ("intervention diet") with the recommended diet for DM ("control diet"). METHODS: 56 subjects with insulin treated DM and gastroparesis were randomized to the intervention diet or the control diet. The patients received dietary advice by a dietitian at 7 occasions during 20 weeks. GI symptom severity, nutrient intake and glycemic control were measured before and after the intervention. RESULTS: A significantly greater reduction of the severity of the key gastroparetic symptoms-nausea/vomiting (P=0.01), postprandial fullness (P=0.02) and bloating (P=0.006)-were seen in patients who received the intervention diet compared with the control diet, and this was also true for regurgitation/heartburn (P=0.02), but not for abdominal pain. Anxiety was reduced after the intervention diet, but not after the control diet, whereas no effect on depression or quality of life was noted in any of the groups. A higher fat intake in the intervention group was noted, but otherwise no differences in body weight, HbA1c or nutrient intake were seen. CONCLUSIONS: A small particle diet improves the key symptoms of gastroparesis in patients with diabetes mellitus. (ClinicalTrials.gov NCT01557296)

A comparison of a short nurse-based and a long multidisciplinary version of structured patient education in irritable bowel syndrome
- 2012
-
In: European Journal of Gastroenterology & Hepatology. - 0954-691X. ; 24:8, s. 950-957
-
Journal article (peer-reviewed)abstract
- Objective Structured multidisciplinary patient group education has positive effects on symptoms, health-related quality of life, and disease-related knowledge in patients with irritable bowel syndrome (IBS), but few studies comparing different forms of educational interventions are available. Our aim was to compare the effects of long multidisciplinary group education with a short nurse-based group education with regard to symptoms, knowledge, quality of life, and satisfaction with the intervention in IBS patients. Methods Patients with IBS according to the Rome II criteria were randomized to either short nurse-based or a long multidisciplinary-based education. The effects were evaluated by self-administered questionnaires at 3, 6, and 12 months after baseline, and compared between the groups. Results No differences in effects were detected in the between-group comparisons at any of the follow-up assessments. However, positive effects on symptoms, knowledge, quality of life, and satisfaction with the intervention were found in both the short and the long version. Conclusion A short, nurse-based educational intervention seems to be as efficacious as a longer multidisciplinary version. In both groups, positive effects on patients' wellbeing were found to a similar extent. This is an important finding that, from a cost-effective perspective, could contribute toward an optimized management of patients with IBS.

Development of an educational intervention for patients with Irritable Bowel Syndrome (IBS): a pilot study.
- 2009
-
In: BMC gastroenterology. - 1471-230X. ; 9
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Many IBS patients experience that they receive limited information and that the health care system does not take their complaints seriously. We aimed to develop a structured patient education, an 'IBS school', and investigate if the efficacy could be evaluated in terms of improved knowledge, symptom severity and health related quality of life (HRQOL). METHODS: The IBS school consisted of six weekly two hour sessions in a group setting. Five different health care professionals were responsible for one session each. Questionnaires covering patients' experience of the education, perceived knowledge about IBS, gastrointestinal symptoms, and HRQOL, were used for evaluation at baseline and at three, six, and twelve months after education. RESULTS: Twelve IBS patients were included. The patients were overall satisfied with the IBS school. In line with this, the gastrointestinal symptoms, HRQOL, and perceived knowledge about IBS improved significantly after the education. CONCLUSION: An IBS school seems to be a proper method to meet the patients' need of information about IBS and also to improve the patients' gastrointestinal symptoms, HRQOL, and knowledge about IBS. Further controlled studies are now needed in larger numbers of patients to confirm these preliminary results in order to implement this intervention in clinical practice.

A Pilot Study of the Effect of Aloe barbadensis Mill. Extract (AVH200 (R)) in Patients with Irritable Bowel Syndrome: a Randomized, Double-Blind, Placebo-Controlled Study
- 2015
-
In: Journal of Gastrointestinal and Liver Diseases. - : Romanian Society of Gastroenterology and Hepatology. - 1841-8724 .- 1842-1121. ; 24:3, s. 275-280

Journal article (peer-reviewed)abstract
- Background & Aims: Few effective treatment options exist for patients with irritable bowel syndrome (IBS), and many patients state the use of aloe vera products reduce their symptoms. The aim of this pilot study was to investigate the effect of Aloe barbadensis Mill. Extract (AVH200 (R)) in adult patients with IBS in a randomized, double-blind, placebo controlled study. Methods: Sixty-eight adult patients diagnosed with IBS according to the Rome III criteria were randomized to receive AVH200 (R) or matching placebo for four weeks. Symptom questionnaires were completed on a weekly basis and the patients were asked if they had had adequate relief of their gastrointestinal symptoms. Results: A tendency towards a higher proportion of responders in the aloe vera group (55%) vs. placebo (31%), (p=0.09) was observed, and the proportion of subjects who reported adequate relief at least 50% of the weeks during the treatment period tended to be larger in the aloe vera vs. placebo group (33% vs. 14%; p=0.12). The overall severity of the gastrointestinal symptoms was reduced in the aloe vera group (314 +/- 83 vs. 257 +/- 107; p=0.003) but not the placebo group (276 +/- 88 vs. 253 +/- 100; NS), without difference between the groups (p=0.10). AVH200 (R) was well tolerated and no serious adverse events were observed. Conclusion: Even though the primary endpoint was not met, AVH200 (R) seems to be a promising treatment option for patients with IBS owing to the positive results seen within the secondary endpoints. This study may have been underpowered to detect a clinically meaningful difference between the treatment groups, and therefore larger randomized, controlled studies are required to confirm these results and to elucidate potential mechanisms explaining its effect.

- The aim of the present study was to investigate whether adult patients with coeliac disease in remission could include large amounts of oats in their daily gluten-free diet for an extended period of time without adverse effects. DESIGN, SUBJECTS AND METHODS: Twenty adult coeliac patients in remission included large amounts of uncontaminated rolled oats in their daily diet for a prolonged period. The examinations, performed four times during the study period, included small bowel endoscopy with biopsies, blood samples (nutritional status, serological analysis), height and body weight, gastrointestinal symptoms and dietary records. Gastrointestinal symptoms and diet were also investigated through unannounced telephone interviews once a month during the study period.

Beneficial effects of oats in the gluten-free diet of adults with special reference to nutrient status, symptoms and subjective experiences
- 2003
-
In: Brit J Nutr. ; 90:1, s. 101-107
-
Journal article (peer-reviewed)abstract
- In several studies oats have been reported to be tolerated by coeliac patients. The aim of the present study was to investigate the nutritional and symptomatic effects of including oats in the gluten-free diet, as well as the patients' subjective experiences. Twenty adult coeliac patients included large amounts of oats in their diet. Food intake, gastrointestinal symptoms, blood samples and body weight were examined and compared with examination at baseline. Diet compliance was checked monthly. The results are based on fifteen patients eating oats for 2 years plus three with only 6-months consumption. The median daily intake of oats was 93 (range 27-137) g/d, and the compliance was good. The mean intakes of Fe and dietary fibre increased (P<0.001) with the oat diet, as well as the intakes of thiamin and Zn (P<0.02). The bioavailability of Fe tended to decrease; this seems not to have influenced the Fe status. Temporary increased flatulence was experienced the first few weeks, as well as improved bowel function with oats in the diet. All patients who carried out the whole study period wanted to continue eating oats after the study, as they found that addition of oats in the gluten-free diet gave more variation, better taste and satiety. Oats improved the nutritional value of the gluten-free diet, had no negative effects on nutritional status and were appreciated by the subjects. Including oats can help coeliac patients following a strict gluten-free diet.
