Patients with irritable bowel syndrome-diarrhea have lower disease-specific quality of life than irritable bowel syndrome-constipation

AIM: To determine effect of irritable bowel syndrome(IBS) subtype on IBS-specific quality of life(QOL) questionnaire and its subscales.METHODS: We studied IBS patients visiting our functional gastroenterology disorder clinic at a tertiary care center of Unites States.IBS and IBS subtype were diagnosed using Rome-Ⅲ questionnaire.QOL was assessed using IBS-QOL questionnaire.IBSQOL assesses quality of life along eight subscales: dysphoria,interference with activities,body image,health worry,food avoidance,social reactions,sexual health,and effect on relationships.IBS-QOL and its subscales were both scored on a range of 0-100 with higher scores suggestive of better QOL.Results of overall IBS-QOL scores and subscale scores are expressed as means with 95%CI.We compared mean IBS-QOL score and its subscales among various IBSsubtypes.Analysis of variance(ANOVA) was used to compare the mean difference between more than two groups after controlling for age and gender.A posthoc analysis using Bonferroni correction was used only when P value for ANOVA was less than 0.05.RESULTS: Of 542 patients screened,243 had IBS as per Rome-Ⅲ criteria.IBS-mixed(IBS-M) was the most common IBS subtype(121 patients,49.8%) followed by IBS- diarrhea(IBS-D)(56 patients,23.1%),IBSconstipation(IBS-C)(54 patients,22.2%) and IBSunspecified(IBS-U)(12 patients,4.9%).Overall IBSQOL scores were significantly different among various IBS-subtypes(P = 0.01).IBS-QOL of patients with IBS-D(61.6,95%CI: 54.0-69.1) and IBS-M(63.0,95%CI: 58.1-68.0) was significantly lower than patients with IBS-C(74.5,95%CI: 66.9-82.1)(P = 0.03 and 0.02 respectively).IBS-D patients scored significantly lower than IBS-C on food avoidance(45.0,95%CI: 34.8-55.2 vs 61.1,95%CI: 50.8-71.3,P = 0.04) and interference with activity(59.6,95%CI: 51.4-67.7 vs 82.3,95%CI: 74.1-90.6,P < 0.001).IBS-M patients had more interference in their activities(61.6,95%CI: 56.3-66.9 vs 82.3,95%CI: 74.1-90.6,P = 0.001) and greater impact on their relationships(73.3,95%CI: 68.4-78.2 vs 84.7,95%CI: 77.2-92.2,P = 0.02) than IBS-C patients.Patients with IBS-M also scored significantly lower than IBS-C on food avoidance(47.2,95%CI: 40.7-53.7 vs 61.1,95%CI: 50.8-71.3,P = 0.04) and social reaction(66.1,95%CI: 61.1-71.1 vs 80.0,95%CI: 72.1-87.7,P = 0.005).CONCLUSION: IBS-D and IBS-M patients have lower IBS-QOL than IBS-C patients.Clinicians should recognize food avoidance,effects on daily activities and relationship problems in these patients.

Effect of Bifidobacterium longum 35624 on disease severity and quality of life in patients with irritable bowel syndrome

BACKGROUND Bifidobacterium longum 35624 has shown efficacy in improving irritable bowel syndrome(IBS)symptoms compared with placebo in double-blind randomized studies.However,few data are available from real-life clinical practice or from studies that used Rome IV criteria to diagnose IBS.AIM To assess the effect of B.longum 35624 on IBS severity and quality of life in a reallife setting.METHODS From November 2018 to January 2020,278 patients with IBS(according to Rome IV criteria)were enrolled in a prospective,open-label,multicenter observational study by private practice gastroenterologists to received one capsule of B.longum 35624(10^(9) colony-forming units)per day for 30 d.Participation in the study was independently proposed to patients during spontaneous consultations.Disease severity(assessed by the IBS severity scoring system)and patient quality of life(assessed by the IBS quality of life questionnaire)were compared between the inclusion visit(baseline)and the visit at the end of 30 d of treatment.The characteristics of patients were described at baseline.Continuous variables comparisons between inclusion and end-of-treatment visits were performed using the t-test and Kruskal-Wallis test.Categorical variables comparisons were performed using theχ^(2) test.RESULTSA total of 233 patients,with a mean age of 51.4 years and composed of 71.2%women,were included in the study.Of these patients,48.1%had moderate IBS and 46.4%had severe IBS.After a 30-d treatment period with one B.longum 35624 capsule per day,a significant decrease in IBS severity was observed compared to baseline(mean±SD,IBS severity scoring system scores:208±104 vs 303±81,P<0.001)and 57%of patients moved to lower severity categories or achieved remission.The quality of life of patients was also improved by the treatment(IBS Quality of Life questionnaire score:68.8±20.9 vs 60.2±20.5;P<0.001)and 63.8%of patients were satisfied with the treatment.CONCLUSION Thirty days of treatment with B.longum 35624 reduces disease severity and improves the quality of life of patients with IBS,particularly those with the most severe forms of IBS.

Age-related symptom and life quality changes in women with irritable bowel syndrome

AIM:To explore age-related changes in symptoms and quality of life(QoL) of women with irritable bowel syndrome(IBS).METHODS:Two-hundred and fifty-four female adult outpatients with IBS attending the Department of Gastroenterology at the First Affiliated Hospital of Nanjing Medical University between January,2008 and October,2008 were approached.Patients with a history of abdominal surgery,mental illness or those who had recently taken psychotropic drugs were excluded.A physician obtained demographic and abdominal symptom data.All patients were asked to complete the Zung Self-Rated Anxiety and Depression Scale(SDS/SAS) and the IBS-specific QoL questionnaire.The patients were divided into six groups according to age,in 10-year increments:18-27 years,28-37 years,38-47 years,48-57 years,58-67 years and 68-75 years(maximum 75 years).Age-related differences of abdominal pain or discomfort were analyzed using ranksum tests.Differences in SDS/SAS and IBS-QoL scores between age groups were analyzed using one-way analysis of variance.Pearson's correlations evaluated potential associations between IBS symptoms,psychological factors and QoL in each age group.RESULTS:There were no differences in the distribution of IBS subtypes between age groups(χ2 = 20.516,P = 0.153).Differences in the severity of abdominal pain/discomfort with age were statistically significant(χ2 = 25.638,P < 0.001);patients aged 48-57 years,58-67 years or 68-75 years had milder abdominal pain/discomfort than those in the younger age groups.The severity of anxiety or depressive symptoms did not differ between age groups(SDS,χ2 = 390.845,P = 0.110;SAS,χ 2 = 360.071,P = 0.220).Differences of IBSQoL scores were statistically significant between age groups(χ2 = 1098.458,P = 0.011).The scores of patients in the 48-57-year group were lower than those in the 18-27-year and 28-37-year groups(48-57-year group vs 18-27-year group,74.88 ± 8.76 vs 79.76 ± 8.63,P = 0.021;48-57-year group vs 28-37-year group,74.88 ± 8.76 vs 79.04 ± 8.32,P = 0.014).The scores in the 68-75-year group were lower than those in the 18-27-year,28-37-year and 38-47-year groups(68-75-year group vs 18-27-year group,71.98 ± 9.83 vs 79.76 ± 8.63,P = 0.003;68-75-year group vs 28-37-year group,71.98 ± 9.83 vs 79.04 ± 8.32,P = 0.002;68-75-year group vs 38-47-year group,71.98 ± 9.83 vs 76.44 ± 8.15,P = 0.039).Anxiety and depression were negatively correlated with QoL in all age groups(SDS and QoL:18-27-year group,r =-0.562,P = 0.005;28-37-year group,r =-0.540,P < 0.001;38-47-year group,r =-0.775,P < 0.001;48-57-year group,r =-0.445,P = 0.001;58-67-year group,r =-0.692,P < 0.001;68-75-year group,r =-0.732,P < 0.001.SAS and QoL:18-27-year group,r =-0.600,P = 0.002;28-37-year group,r =-0.511,P < 0.001;38-47-year group,r =-0.675,P < 0.001;48-57-year group,r =-0.558,58-67-year group,P = 0.001;r =-0.588,P < 0.001;68-75-year group,r =-0.811,P < 0.001).A negative correlation between abdominal pain severity and QoL was found in patients aged more than 58 years(58-67-year group,r =-0.366,P = 0.017;68-75-year group,r =-0.448,P = 0.048),but not in younger patients(18-27-year group,r = 0.080,P = 0.716;28-37-year group,r =-0.063,P = 0.679;38-47-year group,r =-0.029,P = 0.812;48-57-year group,r =-0.022,P = 0.876).CONCLUSION:Factors affecting QoL should always be treated in IBS,especially emotional problems in young adults.Even mild abdominal pain should be controlled in elderly patients.

Ehealth:Low FODMAP diet vs Lactobacillus rhamnosus GG in irritable bowel syndrome

AIM: To investigate the effects of a low fermentable, oligosaccharides, disaccharides, monosaccharides and polyols diet (LFD) and the probiotic Lactobacillus rhamnosus GG (LGG) in irritable bowel syndrome (IBS).

Irritable bowel syndrome symptom severity improves equally with probiotic and placebo

AIM To determine the effects of Lactobacillus acidophilus NCFM on irritable bowel syndrome(IBS) symptoms and quality of life(Qo L).METHODS In this randomized triple-blind trial, adult IBS volunteerswho were recruited according to Rome Ⅲ criteria received 109 or 1010 colony-forming units of NCFM or placebo daily for 12 wk. IBS Symptom Severity Score(IBS-SSS), which constituted the primary outcome, and secondary outcomes, including individual IBS symptoms, IBS-related QoL questionnaire, anxiety and depression, defecation frequency, and stool consistency, were assessed at baseline at the end of the 8-wk runin period, after 4 and 12 wk of intervention, and after a 4-wk washout.RESULTS A total of 340 of 391 randomized volunteers completed the trial. IBS-SSS improved over 12 wk of treatment in all treatment groups, decreasing by a mean ± SD of 44.0 ± 80.2, 50.8 ± 82.4, and 48.3 ± 72.2 in the placebo, active low-dose, and active high-dose groups, respectively. Similarly, secondary outcomes did not differ between treatment groups. However, in a post hoc analysis of volunteers with moderate to severe abdominal pain at baseline(VAS > 35/100), the treatment significantly reduced the sensation of abdominal pain. Pain scores fell by 20.8 ± 22.8, 29.4 ± 17.9, and 31.2 ± 21.9 in the placebo, active low-dose, and active high-dose groups, respectively(P value for placebo vs combined active doses = 0.0460).CONCLUSION NCFM alleviates moderate to severe abdominal pain, consistent with earlier observations of this strain mitigating visceral pain through increased analgesic receptor expression.

psychosocial impact of irritable bowel syndrome: A brief review

Irritable bowel syndrome(IBS) is a common disorder of the gastrointestinal tract with unclear etiology and no reliable biomarker. Like other chronic and functional disorders, medical treatments for IBS are suboptimal and the overall illness burden is high. Patients with IBS report high rates of psychopathology, low quality of life, and increased suicidal ideation. These patients also miss more days of work, are less productive at work, and use many healthcare resources. However, little is known about the burden of IBS on daily functioning. The primary aim of this paper is to review the current literature on the burden of IBS and to highlight the need for further research to evaluate the impact of IBS on daily activities. This research would contribute to our existing understanding of the impact of IBS on overall quality of life and well-being.

Ehealth monitoring in irritable bowel syndrome patients treated with low fermentable oligo-, di-, mono-saccharides and polyols diet

In the present study we report on changes in irritable bowel syndrome-severity scoring system (IBS-SSS) and irritable bowel syndrome-quality of life (IBS-QoL) in 19 IBS patients, aged 18 to 74 years (F/M: 14/5), during 12 wk registering their symptoms on the web-application (www.ibs.constant-care.dk). During a control period of the first 6-wk patients were asked to register their IBS-SSS and IBS-QoL on the web-application weekly without receiving any intervention. Thereafter, low fermentable oligo-, di-, mono-saccharides and polyols (FODMAP) diet (LFD) was introduced for the next 6 wk while continuing the registration. Though a small sample size a significant improvement in disease activity (IBS-SSS) was observed during both the control period, median: 278 (range: 122-377), P = 0.02, and subsequently during the LFD period, median: 151 (range: 29-334), P &#x0003c; 0.01. The IBS-QoL solely changed significantly during the LFD period, median: 67 (37-120), P &#x0003c; 0.01. The significant reduction in disease activity during the control period shows a positive effect of the web-application on IBS symptoms when presented as a &#x0201c;traffic light&#x0201d;. However adding the diet reduced IBS-SSS to &#x0003c; 150, inactive to mild symptoms. In the future results from larger scale trials are awaited.

Saccharomyces cerevisiae I-3856 in irritable bowel syndrome with predominant constipation

BACKGROUND Probiotics are a promising solution for managing irritable bowel syndrome(IBS).Saccharomyces cerevisiae(S.cerevisiae)I-3856 has already demonstrated beneficial effects in IBS subjects,particularly in IBS with predominant constipation(IBS-C).AIM To confirm the efficacy of S.cerevisiae I-3856 in the management of gastrointestinal symptoms in IBS-C.METHODS A randomized,double-blind,placebo-controlled clinical study was performed in a total of 456 subjects.After a run-in period,subjects were randomly assigned to the group receiving S.cerevisiae I-3856(8×109 CFU daily)or the placebo for 8 wk,and they performed daily self-evaluations of gastrointestinal symptoms.The primary objective was to assess the effect of the probiotic on abdominal pain.The secondary objectives were the evaluation of other gastrointestinal symptoms,bowel movement frequency and consistency,and quality of life(QOL).RESULTS A significantly higher proportion of abdominal pain responders was reported in the Probiotic group(45.1%vs 33.9%,P=0.017).A nonsignificant difference in the area under the curve for abdominal pain over the second month of supplementation was observed in subjects receiving probiotic vs placebo[P=0.073,95%CI:-0.59(-1.23;0.05)].No statistically significant differences were reported in the evolution of bowel movement frequency and stool consistency between the groups.After 8 wk of supplementation,the overall QOL score was significantly higher in the Probiotic group than in the Placebo group[P=0.047,95%CI:3.86(0.52;7.20)].Furthermore,exploratory analyses showed statistically significant and clinically relevant improvements in QOL scores in abdominal pain responders vs nonresponders.CONCLUSION The results of this clinical study confirmed the abdominal pain alleviation properties of S.cerevisiae I-3856 in IBS-C.Abdominal pain relief was associated with improved QOL.ClinicalTrials.gov identifier:NCT03150212.

Treatment of Irritable Bowel Syndrome with a Combination of Curcumin, Green Tea and Selenomethionine Has a Positive Effect on Satisfaction with Bowel Habits

Background: Irritable bowel syndrome (IBS) is a common disorder impairing patient’s quality of life. Currently, there is no effective treatment for this syndrome. Coltect is a dietary supplement containing curcumin, green tea and selenomethionine. Aim: To investigate the effects of Coltect on IBS symptoms. Methods: A randomized, prospective, placebo-controlled, double blinded, crossover study. The study population included patients diagnosed with IBS by Rome criteria. Subjects were randomized to receive either Coltect or placebo for 4 weeks, and then received the opposite treatment for 4 weeks following a washout period of 2 weeks. The placebo was a pill, identical in color and size to the Coltect pill, with no active ingredients. Patients completed IBS health-related quality of life, severity score and IBS symptom questionnaires before and after each treatment period. Results: The study included 22 patients, ages 22 – 77 years. Coltect had a positive effect on patients’ satisfaction with their bowel habits (as measured on a scale from 0—Very satisfied to 100—Very unsatisfied). Average score was 70.4 ± 33.1 before and 61.8 ± 29.3 after Coltect treatment (p = 0.037). Other parameters, including abdominal pain, bloating, and effects of IBS on daily activity, symptoms, IBS-related quality of life and general health quality of life were unchanged. Conclusion: Coltect seems to have a positive effect on satisfaction with bowel habits.

Are bowel symptoms and psychosocial features different in irritable bowel syndrome patients with abdominal discomfort compared to abdominal pain?

BACKGROUND The Rome IV criteria eliminated abdominal discomfort for irritable bowel syndrome(IBS), which was previously included in Rome III. There are questions as to whether IBS patients with abdominal discomfort(seen in Rome III but not Rome IV) are different from those with abdominal pain(Rome IV).AIM To compare bowel symptoms and psychosocial features in IBS patients diagnosed with Rome III criteria with abdominal discomfort, abdominal pain, and pain &discomfort.METHODS We studied IBS patients meeting Rome III criteria. We administered the IBS symptom questionnaire, psychological status, and IBS quality of life. Patients were classified according to the predominant abdominal symptom associated with defecation into an only pain group, only discomfort group, and pain & discomfort group. We compared bowel symptoms, extraintestinal symptoms, IBS quality of life, psychological status and healthcare-seeking behaviors, and efficacy among the three groups. Finally, we tested risk factors for symptom reporting in IBS patients.RESULTS Of the 367 Rome III IBS patients enrolled, 33.8%(124 cases) failed to meet Rome IV criteria for an IBS diagnosis. There were no meaningful differences between the pain group(n = 233) and the discomfort group(n = 83) for the following:(1) Frequency of defecatory abdominal pain or discomfort;(2) Bowel habits;(3) Coexisting extragastrointestinal pain;(4) Comorbid anxiety and depression;and(5) IBS quality of life scores except more patients in the discomfort group reported mild symptom than the pain group(22.9% vs 9.0%). There is a significant tendency for patients to report their defecatory and non-defecatory abdominal symptom as pain alone, or discomfort alone, or pain & discomfort(all P < 0.001).CONCLUSION IBS patients with abdominal discomfort have similar bowel symptoms and psychosocial features to those with abdominal pain. IBS symptoms manifesting abdominal pain or discomfort may primarily be due to different sensation and reporting experience.

Assessment of the Efficacy of Rifaximin in the Management of Irritable Bowel Syndrome (IBS)

The aim of our study was to assess in our context, the efficacy of Rifaxim in improving the symptoms of irritable bowel syndrome particularly in its diarrheal (IBS-D) or mixed (IBS-DC) component and therefore assess its impact on patients’ quality of life. Patients and methods: This was an uncontrolled, non-comparative prospective cohort study of a single group of patients. Patients recruitment was done in two University Hospitals for 6 months (September 2015-February 2016). Were included ambulatory patients, male or female, aged 18 - 75 years, with diarrheic IBS (IBS-D) or mixed IBS (IBS-DC) diagnosed according to Rome III criteria and who agreed to participate in the study. Each patient received 400mg Rifaximin × 2/d for 15 days. The overall assessment of the efficacy of treatment at D15 (end of treatment) and D30 (2 weeks post-treatment) was the primary criterion of judgment. The statistical tests used were the Chi-square test and Fisher’s exact test for the qualitative variables and Student’s test for the quantitative variables. Results: A total number of 30 patients (16 women) with an average age of 44.5 ± 13.9 years were included. The overall assessment of symptoms by the patient with the Likert scale found 28 (93.3%) patients, 12 (40%) patients and 10 patients (33.3%) for a scale ≥2 at D0, D15 and D30 respectively. The assessment of the intensity of pain or abdominal discomfort found at D0, D15 and D30 respectively: 27(90%), 13(43.4%) and 6(20.1%) patients who had an EVA score > 2. The mean score for Francis to assess the improved quality of life was 247.1 ± 97.4 at D0, 99.8 ± 63.1 at D15 and 128.8 ± 70.6 at D30. Conclusion: There is a good overall improvement of symptoms in our patients suffering from IBS-D or mixed (IBS-DC) on Rifaximin with improvement of the quality of life.

Chronic gastrointestinal symptoms and quality of life in the Korean population

AIM： To evaluate the prevalence of chronic gastroin- testinal symptoms and their impact on health-related quality of life （HRQOL） in the Korean population. METHODS： A cross-sectional survey, using a reliable and valid Rome I] based questionnaire, was per- formed on randomly selected residents, between 18 and 69 years in age. All respondents were interviewed at their homes or offices by a team of interviewers. The impact of chronic gastrointestinal symptoms on HRQOL was assessed using the Korean version of the 36-item Short-Form general health survey （SF-36）. RESULTS： Of the 1807 eligible subjects, 1417 （78.4%： male 762; female 655） were surveyed. Out of the respondents, 18.6% exhibited at least one chronic gastrointestinal symptom. The prevalence of gastro- esophageal reflux disease （GERD）, defined as heart- burn and/or acid regurgitation experienced at least weekly, was 3.5% （95% CI, 2.6-4.5）. The prevalence of uninvestigated dyspepsia, irritable bowel syndrome （IBS） and chronic constipation based on Rome Ⅱ criteria were 11.7% （95% CI, 10.1-13.5）, 2.2% （95% CI, 1.5-3.1）, and 2.6% （95% CI, 1.8-3.5） respectively. Compared with subjects without chronic gastrointesti- nal symptoms （n = 1153）, those with GERD （n = 50）, uninvestigated dyspepsia （n = 166） and IBS （n = 31） had significantly worse scores on most domains of the SF-36 scales. CONCLUSION： The prevalence of GERD, uninvesti- gated dyspepsia and IBS were 3.5%, 11.7% and 2.2% respectively, in the Korean population. The health- related quality of life was significantly impaired in subjects with GERD, uninvestigated dyspepsia and IBS in this community.

A cross-sectional study of irritable bowel syndrome in nurses in China: prevalence and associated psychological and lifestyle factors

The prevalence of irritable bowel syndrome （IBS） and associated factors, especially psychological and lifestyle factors, in nurses in China have not been investigated previously. The aims of this study were to assess the prevalence of IBS in nurses, to evaluate whether factors, such as psychological disorders, are associated with IBS, and to determine whether psychological disorders can influence the severity of symptoms of IBS and quality of life （QOL）. A cross-sectional study was conducted for Chinese nurses from November 2012 to February 2013. Partici- pants were asked to complete questionnaires. The prevalence of IBS was 17.4%. The revised symptom checklist 90 （SCL-90-R） scores were significantly higher for nurses with IBS than for those without IBS （P〈0.001）, and no difference in scores between IBS subtypes was found （F=1.893, P=-0.142）. The scores of QOL for nurses with and without IBS were 77.18±21.93 and 88.44±11.89 （P〈0.001）, respectively. Psychological disorders did not show statistically significant correlations with severity of symptoms of IBS or QOL. Alcohol consumption, low level of exercise, and psychological disorders were risk factors for IBS. In summary, nurses in China show a high prevalence of IBS. Psy- chological disorders and some related lifestyle factors are probably responsible for the development of IBS in nurses.
