- Objective: Symptomatic gastroesophageal reflux disease (GERD), dyspepsia, and irritable bowel syndrome (IBS) are generally considered to be chronic conditions, but community-based studies are sparse, and long-term natural history data are unavailable. We aimed to determine the natural history of these conditions.Methods: A representative Swedish sample (20-79 yr) completed a validated questionnaire over the preceding 3 months. The survey was repeated after 1 and 7 yr in the same target group (n = 1290, 1260, and 1065; response rates 90%, 87%, and 82%, respectively; 79% responded to all three mailings).Results: The prevalence of GERD symptoms remained stable, whereas the prevalence of IBS increased over time, independent of aging. Dyspepsia decreased with advancing age. Although more than half of those with IBS reported the same symptom profile after 1 and 7 yr, there was a substantial symptom fluctuation and symptom profile flux between those reporting dyspepsia, IBS, or minor symptoms. Only a minority with GERD (<10%) changed to dyspepsia and/or IBS, or vice versa. The symptom-free patients remained symptom-free or reported only minor symptoms in > or = 90% of cases.Conclusion: There seem to be two distinct populations of symptom reporters, those with dyspepsia or IBS, and those with GERD.

- INTRODUCTION: We hypothesized that the prevalence of functional dyspepsia and gastroesophageal reflux disease in the community may be increasing.METHODS: Randomly selected adults were surveyed on 4 occasions: 1988 (n = 1,151, 21–79 years, response rate [rr] = 90%), 1989 (n = 1,097, 22–80 years, rr = 87%), 1995 (n = 1,139, 20–85 years, rr = 76%), and 2011 (n = 1,175, 20–93 years, rr = 63%).RESULTS: In functional dyspepsia, the odds of postprandial distress syndrome tripled over 23 years' follow-up (odds ratio [OR]: 3.55; 95% confidence interval [CI]: 2.60–4.84, mixed-effect regression analysis), whereas a small decrease in epigastric pain syndrome was observed (OR: 0.65, 95% CI: 0.42–1.00). The odds of reporting gastroesophageal reflux disease doubled (OR: 2.02; 95% CI: 1.50–2.73).DISCUSSION: The underlying mechanisms behind the increase in postprandial distress syndrome and gastroesophageal reflux disease remain to be determined.

- OBJECTIVE: The role of the eosinophil granulocyte in bowel mucosa in inflammatory bowel disease still remains obscure. The present study was performed in order to elucidate the local eosinophil activity and activating cytokines in the inflamed lesions of colon and rectum in patients with ulcerative colitis and proctitis. METHODS: The activity of intestinal eosinophils with respect to the release of granule proteins was studied in 18 patients (10 with colitis and 8 with isolated proctitis) and 18 healthy controls, using intraluminal segmental perfusion of the sigmoid colon and rectum. The released amounts of eosinophil granule proteins: eosinophil cationic protein (ECP), eosinophil peroxidase (EPO), and eosinophil protein X (EPX) to perfusion fluid were determined by radioimmunoassays. The intraluminal release of possible eosinophil priming cytokines granulocyte/macrophage-colony stimulating factor (GM-CSF) and interleukin 8 (IL-8), were analyzed by immunoassays. RESULTS: The mucosal release of ECP, EPO, and EPX was increased 10- to 20-fold in patients with colitis and proctitis compared with controls. The intraluminal release of GM-CSF and IL-8, was several-fold enhanced in patients with colitis and proctitis. We also found a correlation between all three eosinophil granule proteins and the levels of IL-8/GM-CSF in the sigmoidal segments of patients with colitis. CONCLUSIONS: We conclude that the increased release of ECP, EPO, and EPX to colorectal perfusion fluid indicate eosinophil involvement in the local disease in patients with colitis and proctitis. IL-8 and GM-CSF may play a role in eosinophil accumulation and priming in colitis.

Validation of Risk Scoring Systems in Ursodeoxycholic Acid-Treated Patients With Primary Biliary Cholangitis
- 2019
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270 .- 1572-0241. ; 114:7, s. 1101-1108
-
Journal article (peer-reviewed)abstract
- INTRODUCTION: Risk stratification based on biochemical variables is a useful tool for monitoring ursodeoxycholic acid (UDCA)-treated patients with primary biliary cholangitis (PBC). Several UDCA response criteria and scoring systems have been proposed for risk prediction in PBC, but these have not been validated in large external cohorts. METHODS: We performed a study on data of 1746 UDCA-treated patients with PBC from 25 centers in Europe, United States, and Canada. The prognostic performance of the risk scoring systems (GLOBE and UK-PBC) and the UDCA response criteria (Barcelona, Paris I, Paris II, Rotterdam, and Toronto) were evaluated. We regarded cirrhosis-related complications (ascites, variceal bleeding, and/or hepatic encephalopathy) as clinical end points. RESULTS: A total of 171 patients reached a clinical end point during a median 7 years (range 1-16 years) of follow-up. The 5-, 10- and 15-year adverse outcome-free survivals were 95%, 85%, and 77%. The GLOBE and UK-PBC scores predicted cirrhosis-related complications better than the UDCA response criteria. The hazard ratio (HR) for a 1 standard deviation increase was HR 5.05 (95% confidence interval (CI): 4.43-5.74, P < 0.001) for the GLOBE score and HR 3.39 (95% CI: 3.10-3.72, P < 0.001) for the UK-PBC score. Overall, the GLOBE and UK-PBC risk scores showed similar and excellent prognostic performance (C-statistic, 0.93; 95% CI: 0.91%-95% vs 0.94; 95% CI: 0.91%-0.96%). DISCUSSION: In our international, multicenter PBC cohort, the GLOBE and UK-PBC risk scoring systems were good predictors of future cirrhosis-related complications.

Characteristics of Acute Pain Attacks in Patients With Irritable Bowel Syndrome Meeting Rome III Criteria
- 2011
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270 .- 1572-0241. ; 106:7, s. 1299-1307
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: An international multicenter, prospective, non-interventional, 2-month study characterized acute pain attacks in patients with irritable bowel syndrome (IBS). METHODS: Adult patients meeting the Rome III IBS diagnostic criteria with a history of >= 3 pain attacks per month participated in a survey that captured daily and episodic information regarding IBS symptoms and pain attacks for 2 months. Acute pain attacks were defined as a sudden onset or increase in the intensity of IBS abdominal pain with a minimum intensity of 4 (0-10 scale). RESULTS: The majority (84%) of the 158 patients taking the survey were women with a mean age of 41 years and time since IBS diagnosis of 5 years. The median pain attack frequency was 5.4 attacks per month and was significantly higher in the IBS with diarrhea (IBS-D, 6.4 per month) group vs. the IBS with constipation (4.4 per month) and the IBS with mixed pattern (5.5 per month) groups (P = 0.019). The median pain attack duration was 2.8 h and the median intensity score was 7. The majority of pain attacks resulted in defecation (78%), and occurred more often in IBS-D patients than in other subgroups. The majority of pain attacks (63%) interfered with work and/or daily activities. Medication to manage pain attacks was used by 44% of patients during 29% of attacks. Although used by less than half of all patients, medication helped 66% of attacks treated. CONCLUSIONS: The frequency of severe pain attacks was 1.4 per week and the majority affected daily activities. However, most of the pain attacks were untreated in IBS patients. Pain attack management is an unmet need of IBS treatment.

Journal article (peer-reviewed)abstract
- OBJECTIVES: Lifestyle factors other than dietary fiber intake and risk for colonic diverticular disease have only been examined in few studies. The objective of this study was to investigate the association between obesity and physical inactivity and diverticular disease in a population-based cohort of women. METHODS: This was a prospective population-based cohort study. In all, 36,592 women, born 1914-1948, in the Swedish Mammography Cohort were followed 1997-2009. Body mass index (BMI; kg/m(2)), physical activity, diet, smoking, and other lifestyle factors were collected at baseline through questionnaires. Cases of diverticular disease were identified from the Swedish Patient and Death Registers. Relative risks (RRs) of diverticular disease requiring hospitalization (or being the cause of death) according to BMI and physical activity were estimated using Cox proportional hazards models. The multivariable models were adjusted for age; intake of dietary fiber; diabetes; hypertension; use of acetylsalicylate acid, non-steroid anti-inflammatory drug, or steroid medication; alcohol consumption; smoking; and educational level. RESULTS: During 12 years, 626 cases of incident diverticular disease requiring hospitalization were found. Two women were registered in the National Death Register only. In multivariable analysis, women with BMI 25-29.99 had 29% increased risk (RR=1.29; 95% confidence interval (CI): 1.08, 1.54) and obese women (BMI >= 30) had 33% (1.33; 95% CI: 1.03-1.72) increased risk of diverticular disease compared to women with BMI 20-24.99. Exercise <= 30 min/day increased the risk for disease with 42% (1.42; 95% CI: 1.18-1.69) compared with exercise >30 min/day in multivariable analysis. Ninety-eight subjects were hospitalized due to complications; perforation or abscess. Women with BMI >= 30 had a twofold (RR=2.00; 95% CI: 1.08-3.73; P=0.028) increased risk for complicated disease. CONCLUSIONS: Overweight, obesity, and physical inactivity among women increase diverticular disease requiring hospitalization.

Prospective Study of Glycemic Load, Glycemic Index, and Carbohydrate Intake in Relation to Risk of Biliary Tract Cancer
- 2016
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270 .- 1572-0241. ; 111:6, s. 891-6

Journal article (peer-reviewed)abstract
- OBJECTIVES: Diets that induce a high glycemic response might increase the risk of biliary tract cancer (BTC). We evaluated the hypothesis that diets with high glycemic load (GL) and high glycemic index (GI), which are measures of the glycemic effect of foods, are associated with an increased incidence of BTC.METHODS: We used data from a population-based prospective study of 76,014 Swedish adults (age 45-83 years; 57% men) who were free of cancer and had completed a food-frequency questionnaire in the autumn of 1997. Incident cancer cases were ascertained by linkage with the Swedish Cancer Registry. Data were analyzed using Cox proportional hazards regression models.RESULTS: During a mean follow-up of 13.3 years (1,010,777 person-years), we identified 140 extrahepatic BTC cases (including 77 gallbladder cancers) and 23 intrahepatic BTC cases. A high dietary GL was associated with an increased risk of BTC. The multivariable relative risks for the highest versus lowest quartile of dietary GL were 1.63 (95% confidence interval (95% CI), 1.01-2.63) for extrahepatic BTC, 2.14 (95% CI, 1.06-4.33) for gallbladder cancer, and 3.46 (95% CI, 1.22-9.84) for intrahepatic BTC. Dietary GI was statistically significantly positively associated with risk of extrahepatic BTC and gallbladder cancer. We observed no statistically significant association between carbohydrate intake and BTC risk, although all associations were positive.CONCLUSION: Although these data do not prove a causal relationship, they are consistent with the hypothesis that high-GL and high-GI diets are associated with an increased risk of BTC.

Internet-Delivered Exposure-Based Treatment vs. Stress Management for Irritable Bowel Syndrome : A Randomized Trial
- 2011
-
In: American Journal of Gastroenterology. - : Ovid Technologies (Wolters Kluwer Health). - 0002-9270 .- 1572-0241. ; 106:8, s. 1481-1491
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: Our research group has developed an internet-delivered cognitive behavioral treatment (ICBT) for irritable bowel syndrome (IBS). We compared ICBT with internet-delivered stress management (ISM) for IBS to assess whether the effects of ICBT are specific. METHODS: This was a randomized controlled trial, including 195 self-referred participants diagnosed with IBS. The treatment interventions lasted for 10 weeks and included an online therapist contact. The ICBT emphasized acceptance of symptoms through exposure to IBS symptoms and related negative feelings. The ICBT also included mindfulness training. The ISM emphasized symptom control through relaxation techniques, dietary adjustments, and problem-solving skills. Severity of IBS symptoms was measured with the gastrointestinal symptom rating scale-IBS version (GSRS-IBS). Credibility of the treatments and expectancy of improvement were assessed with the treatment credibility scale. The participants' perceived therapeutic alliance with their online therapist was measured with the working alliance inventory. RESULTS: At post-treatment and 6-month follow-up, 192 (99%) and 169 (87%) participants returned data, respectively. At post-treatment and 6-month follow-up, we found significant differences on the GSRS-IBS, favoring ICBT. The difference on GSRS-IBS scores was 4.8 (95% confidence interval (CI): 1.2-8.4) at post-treatment and 5.9 (95% CI: 1.9-9.9) at 6-month follow-up. There were no significant differences on the treatment credibility scale or the working alliance inventory between the groups. CONCLUSIONS: Internet-delivered CBT has specific effects that cannot be attributed only to treatment credibility, expectancy of improvement, therapeutic alliance, or attention. Furthermore, a treatment based on exposure exercises specifically tailored for IBS may be a better treatment option than general stress and symptom management for IBS patients. ICBT is a promising treatment modality for IBS as it can be offered to IBS patients in much larger scale than conventional psychological treatments.
