    • Objectives: Helicobacter pylori (H. pylori) is associated with peptic ulcers and gastric cancer and its eradication aims to prevent these conditions. The recommended eradication regimen is triple therapy, consisting of a proton pump inhibitor in combination with clarithromycin and amoxicillin or metronidazole for 7 days. Yet, other antibiotic regimens are sometimes prescribed. We aimed to assess the use of eradication therapy for H. pylori in the Swedish population during the last decade. Materials and Methods: This population-based study used data from the Swedish Prescribed Drug Register. From July 2005 until December 2014, all regimens that can eradicate H. pylori were identified and evaluated according to patients’ age and sex and calendar year of eradication. Results: We identified 157,915 eradication episodes in 140,391 individuals (53.8% women, 42.6% older than 60 years), who correspond to 1.5% of the Swedish population. The absolute number and incidence of eradications decreased over the study period. Overall, 91.0% had 1 eradication and 0.1% had more than 3. Of all eradications, 95.4% followed the recommended regimen, while 4.7% did not. The latter group was overrepresented among individuals aged ≥80 years (7.8%). Amoxicillin and clarithromycin were most frequently prescribed, while metronidazole was rarely used (0.01%). Other prescribed antibiotics were ciprofloxacin (2.4%), doxycycline (1.4%), nitrofurantoin (0.7%), norfloxacin (0.5%) and erythromycin (0.3%). Conclusions: During the last decade in Sweden H. pylori eradication has been frequently prescribed, but the incidence of eradication has slowly declined. Most eradications followed the recommended regimen, including those occurring after a previous eradication.

  • Snus and risk of gastroesophageal reflux : a population-based case-control study : the HUNT study
  • 2017
  • Ingår i: Scandinavian Journal of Gastroenterology. - Stockholm : Karolinska Institutet, Dept of Molecular Medicine and Surgery. - 0036-5521 .- 1502-7708.

    • Objective: Tobacco smoking is a risk factor for gastroesophageal reflux, but whether other tobacco products increase the risk is unclear. The aim of this study was to investigate if snus increases the risk of gastroesophageal reflux symptoms (GERS). Material and Methods: The study was based on the third Nord-Trøndelag health study (HUNT3), a population-based study of all adult residents in Nord-Trøndelag County, Norway, performed in 2006−2009. The association between self-reported severe heartburn/regurgitation and snus use was assessed by logistic regression. Results: Compared to never snus users, daily snus users had a reduced risk of GERS (OR 0.77, 95% CI 0.64−0.93), while previous snus users and those using <2 boxes of snus/month had an increased risk (OR 1.20, 95% CI 1.00−1.46 and 1.41, 95% CI 1.02−1.96, respectively). There was no association between age when starting using snus and GERS. Snus users who started using snus to quit or cut down on cigarette smoking, who started using both snus and cigarettes or cigarettes alone had an increased risk of GERS. Snus users <30 years of age had an increased risk of GERS (OR 1.49, 95% CI 1.02−2.16), while those aged between 50−60 and 60−70 years had a reduced risk (OR 0.67, 95% CI 0.49−0.93 and 0.51, 95% CI 0.28−0.94, respectively). Conclusions: Daily snus users had a reduced risk of GERS. However, previous snus users and subgroups of snus users had an increased risk of GERS indicating reverse causality, such that snus use could increase the risk of GERS.

  • Altered bile acid metabolism in patients with constipation-predominant irritable bowel syndrome and functional constipation
  • 2008
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 43:12, s. 1483-1488
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. Bile acids are derived from cholesterol and are potent physiological laxatives. The aim of this study was to investigate whether bile acid synthesis is altered in constipation. Material and methods. Female patients with constipation (23 IBS-C, 4 functional constipation (FC)) were studied and compared with non-constipated subjects (16 IBS-D, 20 healthy women). Body mass index (BMI), blood lipids, lanosterol, sitosterol, colonic transit (oro-anal transit time (OATT), reference=4.3 days) and stool frequency were measured. C4 (7--hydroxy-4-cholesten-3-one) levels reflecting bile acid synthesis were measured at 0800 h and 1300 h. Results. When all the groups of constipated and non-constipated subjects were compared, it was found that only stool frequency and OATT differed between groups (p 0.001). When constipated patients were categorized according to OATT, absence of the usual C4 increase at lunchtime was noted in 82% of patients with delayed OATT compared with 17% in subjects with normal OATT (p 0.001). Symptom severity did not differ between groups. A subset of the patients with severely delayed OATT had markedly elevated C4 levels. Conclusions. Patients with IBS-C and FC have marked changes in bile acid synthesis in relation to colonic transit. The diurnal rhythm is altered in the slow transit colon when there is no C4 peak at lunchtime. Alterations in bile acid metabolism may be implicated in the pathophysiology of constipation.

  • Familial intestinal degenerative neuropathy with chronic intestinal pseudo-obstruction linked to a gene locus with duplication in chromosome 9
  • 2019
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 54:12, s. 1441-1447
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Intestinal degenerative neuropathy without extra-intestinal involvement occurs as familial forms (FIDN) but the genetics behind is unknown. We studied a Swedish family with autosomal dominant disease and several cases of chronic intestinal pseudo-obstruction (CIP). Methods: We included 33 members of a family sharing a male ancestor. Chronic intestinal symptoms including diarrhoea occurred in 11, four had severe CIP. DNA was analysed with SNP-microarray (Affymetrix), linkage (Allegro Software) and gene dosage (CNAG 3.0). Results: Genetic linkage was found to the short arm of Ch9 to a 9.7 Mb region with 45 protein-coding genes, 22 of which were duplicated (1.2 Mb duplication) (dup(9)(p21.3) with breaking point in the FOCAD-gene. Lod score for the region was 3.4. Fourteen subjects were duplication carriers including all 11 subjects having severe chronic symptoms/CIP. Nineteen subjects had no duplication. The occurrence of gastrointestinal symptoms in the family was strongly linked to duplication carrier-ship (p = .0005). The two branches of the family had separate maternal ancestors (A and B). Including the previous generation, severe disease (overt CIP and/or death from intestinal failure) was assessed to occur in 100% (5/5) of duplication carriers in branch A and in 21% (3/14) in branch B (p = .005). In branch B the onset of symptoms was later (median 38 vs. 24 yrs) and three duplication carriers were symptom-free. Conclusions: In this family with autosomal dominant hereditary intestinal neuropathy, the disorder is linked to a 9.7 Mb region in Ch9 including a 1.2 Mb duplication. There is a significant difference in disease expressivity between family branches, seemingly related to separate maternal ancestors.

  • Fatal colonic ischaemia : A population-based study
  • 2006
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 0036-5521 .- 1502-7708. ; 41:11, s. 1312-1319
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives. To estimate the incidence of fatal colonic ischaemia (CI) and the cause-specific mortality of CI, and to describe the localization and extension of colonic infarction and quantify the risk factors associated with CI. Material and methods. Between 1970 and 1982 the autopsy rate in Malmo, Sweden, was 87%, creating the possibilities for a population-based study. Out of 23,446 clinical autopsies, 997 cases were coded for intestinal ischaemia in a database. In addition, 7569 forensic autopsy protocols were analysed. In a case-control study nested in the clinical autopsy cohort, four CI-free controls, matched for gender, age at death and year of death, were identified for each fatal CI case in order to evaluate the risk factors. Results. The cause-specific mortality ratio was 1.7/1000 autopsies. The overall incidence of autopsy-verified fatal CI was 1.7/100,000 person years, increasing with age up to 23/100,000 person years in octogenarians. Fatal cardiac failure (odds ratio (OR) 5.2), fatal valvular disease (OR 4.3), previous stroke (OR 2.5) and recent surgery (OR 3.4) were risk factors for fatal CI. Narrowing/occlusion of the inferior mesenteric artery (IMA) at the aortic origin was present in 68% of the patients. The most common segments affected by transmural infarctions were the sigmoid (83%) and the descending (77%) colon. Conclusions. Heart failure, atherosclerotic occlusion/stenoses of the IMA and recent surgery were the main risk factors causing colonic hypoperfusion and infarction. Segments of transmural infarctions were observed within the left colon in 94% of the patients. Awareness of the diagnosis and its associated cardiac comorbidities might help to improve survival.

  • Loop-ileostomy reversal in a 23-h stay setting is safe with high patient satisfaction
  • 2021
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Taylor & Francis Group. - 0036-5521 .- 1502-7708. ; 56:9, s. 1126-1130
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: This study aimed to determine whether day-case closure of loop ileostomy with discharge within 23 h was both feasible and accepted by patients.Materials and methods: We conducted a prospective pilot study where selected rectal cancer patients with diverting loop ileostomy underwent stoma closure in a 23-h stay setting. Patients were followed up on the third, seventh, and 30th postoperative day and phoned daily during the first week. A comparable group of 30 patients who underwent standard in-hospital stoma closure prior to the start of the study were selected retrospectively as historical controls.Results: In total, 30 patients (median age, 67 years; range, 41-79 years) were included. All patients met discharge criteria and were discharged within 23 h of surgery, except one. In total, seven patients (23%) were admitted. Two of these patients underwent laparotomy because of anastomotic leakage and small bowel obstruction, respectively. The mean total length of stay was 1.7 days. Most patients (87%) were satisfied with the treatment without feeling neglected or anxious and preferred the 23-h stay setting. In the control group, the mean length of stay was 5 days. Seven patients (23%) were readmitted. Two of these patients underwent laparotomy because of small bowel obstruction and abscess, respectively.Conclusion: Ileostomy closure in a 23-h stay setting in selected patients with meticulous follow up is feasible and safe with high patient satisfaction.

  • Coeliac disease-specific tissue transglutaminase autoantibodies are associated with osteoporosis and related fractures in middle-aged women
  • 2009
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 1502-7708 .- 0036-5521. ; 44:5, s. 571-578
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To investigate whether the serological marker for coeliac disease, tissue transglutaminase autoantibody (tTGAb), is associated with decreased bone mass density (BMD) and increased frequency of fractures in middle-aged women screened for osteoporosis. Material and methods. The study comprised 6480 women (mean age 56 years, range 50-64) who answered a number of questionnaires and who underwent dual X-ray absorptiometry of the wrist bone. Serum samples were analysed for tTGAb using radioligand binding assays. A tTGAb level of 4 U/ml was used to determine a positive value and a level of 17 U/ml was used as an alternative discrimination of high levels. Results. A tTGAb level 4 U/ml was found among 90/6480 (1.4%) women and correlated with lower BMD (multiple linear regression coefficient -382.1; 95% CI = - 673.6-90.7, p=0.011) and with fracture frequency (r=0.18, p=0.023). The 59 women with tTGAb levels 17 U/ml had a lower BMD (0.410.08 g/cm2 versus 0.440.08 g/cm2, p=0.001) and a lower T-score (-1.401.28 versus -0.901.40, p=0.003) as well as a higher prevalence of osteoporosis (13.4% versus 6.5%, p=0.008) compared with the remaining 6421 women with tTGAb levels 17 U/ml. Furthermore, fracture frequency was more pronounced in women with tTGAb levels 17 U/ml, among whom 19/59 (32.2%) had fractures during the study period compared with 1204/6421 (18.8%) among women with tTGAb levels 17 U/ml (p=0.009). Conclusions. High levels of tTGAb indicating coeliac disease are associated with lower BMD and higher fracture frequency in women between 50 and 64 years of age. Osteometry is therefore warranted in middle-aged women detected with tTGAb.
