- Primary aldosteronism is the most common cause of secondary hypertension with an estimated prevalence of 5-13 % among patients with hypertension. The most common causes are aldosterone producing adrenal adenoma and idiopathic adrenal hyperplasia. Patients with primary aldosteronism have a higher prevalence of cardiovascular morbidity and mortality compared to patients with essential hypertension. An effective treatment is available for patients with primary aldosteronism, with mineralocorticoid receptor antagonists in bilateral, and minimal invasive adrenal surgery in unilateral disease, which emphasizes the importance of early detection, adequate diagnostic work-up and treatment. In this paper we give a short review of the etiology, pathophysiology, co-morbidities, screening, diagnostic work-up, treatment, and treatment outcomes of primary aldosteronism.

- Objective. Scintigraphy is the gold standard for objective measurement of delayed gastric tube emptying after esophagectomy. The aim of this pilot study is to validate, by reference to scintigraphy, the paracetamol absorption test for measuring gastric tube emptying in esophagectomized patients. Material and methods. The paracetamol absorption test and scintigraphy were performed simultaneously in 13 patients who had undergone an esophagectomy with gastric tube reconstruction. Emptying was calculated for both methods and compared. Post-esophagectomy symptoms and quality of life (QoL) were assessed by European Organization on Research and Treatment of Cancer questionnaires. Results. Mean time to 50% emptying was 17 min measured with the paracetamol absorption test and 23 min with scintigraphy. For time to 25% emptying, Bland-Altman calculation gave a bias of 1.6 min and 95% limits of agreement (LoA) of -6.3 to 9.5 min. For time to 50% emptying, there was one outlier resulting in a bias of -6.33 min and 95% LoA of -36.4 to 23.8 min. For time to 75% emptying, bias was -11.6 min and 95% LoA of -38.5 to 15.4 min. Post-esophagectomy symptoms were similar to those reported previously, and QoL was comparable to the general Swedish population. Conclusions. There was reasonably close correlation between the paracetamol absorption test and scintigraphy for time to 25% and 50% emptying, except for one outlier. For time to 75% emptying the methods were in less accordance. The results indicate that the paracetamol absorption test may be a useful screening tool for identifying delayed gastric tube emptying in this patient group.

- OBJECTIVES: To evaluate the gluten-free diet (GFD) adherenceafter one year of follow-up in children with screening-detected celiac disease (CD) in a general population. METHODS: A total of 18,325 12 year olds were invited to participate in apopulation-based CD screening (ETICS- Exploring the Iceberg of Celiacs in Sweden), of whom 13,279 participated. In 240 children, CD was detected through elevated anti-tissue transglutaminase antibodies 2 (TG2-IgA) and verified by a small-intestinal biopsy. This sub-study included the 210 children with TG2-IgAevaluated both at the initialbiopsy occasion and at the one-year follow-up. GFD adherence was evaluated by a combination of TG2-IgA measurements and self-reported adherence (n = 193). RESULTS: After one year, 83% (179/210) had normalizedTG2-IgA levels (<5U/mL). Among those who had >50 U/mL at diagnosis,25% (16/63) still had elevated TG2-IgA but for the majority their initial values were more than halved. Most reported a high level ofGFD adherence ('always' 75%(158/193) and 'often' 14%(30/193)), and 75% (145/193) reported always adhereingcombined with normalized TG2-IgA. Although reporting that they were always adherent, 13 (6.7%) had not yet normalized their TG2-IgA levels completely, however, a majority of these initially had the highestTG2-IgA levels. CONCLUSIONS: GFD adherence is high in adolescents with CD detected by screening of the general population of Swedish 12yearolds. Almost all had normalized serology and reported GFD adherenceat the one-year follow-up. However, a few adolescents whoreported GFD adherence still had elevated TG2-IgA levelssuggesting more severe disease and/or non-adherence.

Irritable Bowel Syndrome : Studies of central pathophysiological mechanisms and effects of treatment
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background and aimsIrritable bowel syndrome (IBS) is a common gastrointestinal disorder characterized by abdominal pain and altered bowel habits. The societal costs of the disorder are significant, as are its negative effects on quality of life. Medical treatment options are limited, but psychological treatments such as hypnotherapy have proven to be effective. Important pathophysiological mechanisms include disturbances in brain processing of visceral sensation and expectation of visceral sensation. Increased sensation of stimuli (hypersensitivity) is present in a subset of IBS patients to distensions in the lower part of the gastrointestinal tract, indicating a probable important pathophysiological mechanism in IBS. The overall aim of the thesis was to further study the central pathophysiological mechanisms involved in IBS. Specifically, we aimed to identify differences in brain response to standardized repeated rectal distensions and expectation of these stimuli between IBS patients (with or without perceptual rectal hypersensitivity), and healthy controls. Furthermore, we aimed to investigate IBS patients´ brain responses to standardized rectal distensions and expectation of these stimuli after either a successful course hypnotherapy or educational intervention.MethodsFunctional magnetic resonance imaging (fMRI) data were acquired and analyzed from 15 IBS patients with visceral hypersensitivity, and 18 IBS patients with normal visceral sensitivity (papers I and II). In paper III, fMRI data were analyzed from IBS patients who reported significant symptom reduction after either a course of hypnotherapy, or an educational intervention. FMRI data from IBS patients and healthy controls were also compared.ResultsThe findings reported in papers I and II suggest, that the differences in brain response between IBS patients with and without rectal hypersensitivity, can be explained by changes in brain response during the course of the experiment. Even though the brain responses were similar between groups during the early phase of the experiment, they became substantially different during the late phase. The IBS patients with rectal hypersensitivity demonstrated increased brain response in several brain regions and networks involved in visceral sensation and processing. In contrast, IBS patients with normal rectal sensitivity exhibited reduced brain response during the late phase of the experiment. As reported in paper III, similar symptom reduction was achieved for both treatments. The symptomatic improvement was associated with a reduction of response in the anterior insula, indicating an attenuated awareness of the stimuli. The hypnotherapy group had a reduction of response in the posterior insula, indicating less input to the brain, possibly due to changed activity in endogenous pain modulatory systems. In patients who reported significant symptom reduction following treatment, the brain response to rectal distension got more similar to that observed in healthy controls.ConclusionsThe results from papers I and II indicate that a subpopulation of IBS patients lacks the ability to habituate to repeated rectal distensions and expectation of these stimuli. Results from paper III indicate that the abnormal processing of visceral stimuli in IBS can be altered, and that the treatments probably had a normalizing effect on the central processing abnormality of visceral signals in IBS.

- Parastomal herniation is reported in up to 50 % of patients with a colostomy. A prophylactic stoma mesh has been reported to reduce parastomal hernia rates. The aim of the study was to evaluate the rate of parastomal hernias in a population-based cohort of patients, operated with and without a prophylactic mesh at two different time periods. All rectal cancer patients operated with an abdominoperineal excision or Hartmann's procedure between 1996 and 2012 were included. From 2007, a prophylactic stoma mesh was placed in the retro-muscular plane. Patients were followed prospectively with clinical and computed tomography examinations. There were no differences with regard to age, gender, pre-operative albumin levels, ASA score, body mass index (BMI), smoking or type of surgical resection between patients with (n = 71) and without a stoma mesh (n = 135). After a minimum follow-up of 1 year, 187 (91 %) of the patients were alive and available for analysis. At clinical and computed tomography examinations, exactly the same parastomal hernia rates were found in the two groups, viz, 25 and 53 %, respectively (p = 0.95 and p = 0.18). The hernia sac contained omentum or intestinal loops in 26 (81 %) versus 26 (60 %) patients with and without a mesh, respectively (p = 0.155). In the multivariate analyses, high BMI was associated with parastomal hernia formation. A prophylactic stoma mesh did not reduce the rate of clinically or computed tomography-verified parastomal hernias. High BMI was associated with an increased risk of parastomal hernia formation regardless of prophylactic stoma mesh.

- AIM: To examine whether muscle training with an oral IQoro(R) screen (IQS) improves esophageal dysphagia and reflux symptoms. METHODS: A total of 43 adult patients (21 women and 22 men) were consecutively referred to a swallowing center for the treatment and investigation of long-lasting nonstenotic esophageal dysphagia. Hiatal hernia was confirmed by radiologic examination in 21 patients before enrollment in the study (group A; median age 52 years, range: 19-85 years). No hiatal hernia was detected by radiologic examination in the remaining 22 patients (group B; median age 57 years, range: 22-85 years). Before and after training with an oral IQS for 6-8 mo, the patients were evaluated using a symptom questionnaire (esophageal dysphagia and acid chest symptoms; score 0-3), visual analogue scale (ability to swallow food: score 0-100), lip force test (>= 15 N), velopharyngeal closure test (>= 10 s), orofacial motor tests, and an oral sensory test. Another twelve patients (median age 53 years, range: 22-68 years) with hiatal hernia were evaluated using oral IQS traction maneuvers with pressure recordings of the upper esophageal sphincter and hiatus canal as assessed by high-resolution manometry. RESULTS: Esophageal dysphagia was present in all 43 patients at entry, and 98% of patients showed improvement after IQS training [mean score (range): 2.5 (1-3) vs 0.9 (0-2), P < 0.001]. Symptoms of reflux were reported before training in 86% of the patients who showed improvement at follow-up [1.7 (0-3) vs 0.5 (0-2), P < 0.001). The visual analogue scale scores were classified as pathologic in all 43 patients, and 100% showed improvement after IQS training [71 (30-100) vs 22 (0-50), P < 0.001]. No significant difference in symptom frequency was found between groups A and B before or after IQS training. The lip force test [31 N (12-80 N) vs 54 N (27-116), P < 0.001] and velopharyngeal closure test values [28 s (5-74 s) vs 34 s (13-80 s), P < 0.001] were significantly higher after IQS training. The oral IQS traction results showed an increase in mean pressure in the diaphragmatic hiatus region from 0 mmHg at rest (range: 0-0 mmHG) to 65 mmHg (range: 20-100 mmHg). CONCLUSION: Oral IQS training can relieve/improve esophageal dysphagia and reflux symptoms in adults, likely due to improved hiatal competence.

- Goals:To evaluate validity, reliability, and responsiveness of the Short Health Scale (SHS) in irritable bowel syndrome (IBS) patients.Background:Subjective health assessment is central when treating patients with IBS. The Short Health Scale is a quick 4-item questionnaire covering most aspects of subjective health that has been validated for inflammatory bowel disease.Study:To test validity, 451 patients with IBS (mean age, 38 y; 81% females) completed the SHS and questionnaires assessing IBS symptom severity (IBS-SSS), gastrointestinal (GI)-specific anxiety (VSI), and quality of life (IBSQOL). To evaluate reliability and responsiveness to changes, the questionnaires were repeated after 2 weeks in 18 patients, and after 12 weeks in 212 patients who had completed a patient-education program.Results:Validity was documented with (1) gradually increasing mean scores for all 4 SHS items with increasing IBS-SSS (Pless than0.0001), and (2) correlations between the 4 SHS items and the corresponding items from the other subjective health assessment tools [item 1 (symptom burden): =0.67, item 2 (daily function): =-0.44 to -0.46, item 3 (disease-related worry): =-0.51 to 0.57, item 4 (general well-being): =-0.34 to -0.46, Pless than0.0001]. Reliability was confirmed (Spearman greater than0.7 and intraclass correlations greater than0.7). Responsiveness was good with responders to the patient-education program (IBS-SSS reduction 50 points) having significant reductions in 3 of the SHS items (Pless than0.05), and borderline change for the fourth SHS item (P=0.06).Conclusions:SHS is a health measure that shows promising evidence of validity, reliability, and responsiveness in IBS patients. It is quickly completed and evaluated, which supports its usefulness in the busy clinical practice.
