- Background and Aims Hepatitis delta virus (HDV) infection is associated with fast progression to liver cirrhosis and liver complications. Previous studies have, however, been mainly from tertiary care centers, with risk for referral bias toward patients with worse outcomes. Furthermore, the impact of HDV viremiaper seon liver-related outcomes is not really known outside the human immunodeficiency virus co-infection setting. We have therefore evaluated the long-term impact of HDV viremia on liver-related outcomes in a nationwide cohort of patients with hepatitis B and D co-infection, cared for at secondary care centers in Sweden. Approach and Results In total, 337 patients with anti-HDV positivity, including 233 patients with HDV RNA viremia and 91 without HDV viremia at baseline, were retrospectively studied, with a mean follow-up of 6.5 years (range, 0.5-33.1). The long-term risks for liver-related events (i.e., hepatocellular carcinoma [HCC], hepatic decompensation, or liver-related death/transplantation) were assessed, using Cox regression analysis. The risk for liver-related events and HCC was 3.8-fold and 2.6-fold higher, respectively, in patients with HDV viremia compared with those without viremia, although the latter was not statistically significant. Among patients with HDV viremia with no baseline cirrhosis, the cumulative risk of being free of liver cirrhosis or liver-related events was 81.9% and 64.0% after 5 and 10 years of follow-up, respectively. This corresponds to an incidence rate of 0.04 cases per person-year. Conclusions HDV RNA viremia is associated with a 3.8-fold higher risk for liver-related outcomes. The prognosis was rather poor for patients with HDV viremia without cirrhosis at baseline, but it was nevertheless more benign than previous estimates from tertiary centers. Our findings may be of importance when making decisions about treatment and evaluating potential outcomes of upcoming antivirals against HDV.

- Collagenous gastritis (CG), a rare disorder of unknown etiology, has been postulated to have immune-mediated mechanisms. We investigated (i) the incidence and prevalence of CG in a pediatric population; (ii) the clinical, endoscopic, and histologic characteristics of childhood-onset CG; and (iii) the evidence for autoimmunity and/or inflammatory activity in these patients.Clinical, endoscopic, and histologic data were reviewed longitudinally in a population-based Swedish cohort of 15 patients with childhood-onset CG diagnosed in the period 2008-2019. A set of 11 autoantibodies, 4 blood inflammatory biomarkers, and the human leukocyte antigen DQ2/DQ8 genotype was analyzed cross-sectionally.The incidence rate of childhood-onset CG was 0.25/100,000 person-years, with an incidence rate ratio of girls to boys of 4.2 (95% confidence interval, 1.2-15). The prevalence of CG was 2.1/100,000 in children aged younger than 18 years. The endoscopic and histologic findings remained pathologic in all the examined patients during a median follow-up of 4.4 years. Many patients had heredity for autoimmune disorders (47%) and/or tested positive for autoantibodies (40%) or human leukocyte antigen DQ2/DQ8 (53%). No associated autoimmune comorbidities were observed. The serum levels of calprotectin and amyloid A were increased in 10/15 (67%) and 5/15 (33%) of the patients, respectively, whereas plasma C-reactive protein levels were normal in all, but 1 patient.The results indicate that childhood-onset CG is rare and has a chronic disease course. Although signs of autoimmune predisposition are frequent, early development of autoimmune comorbidities seems seldom. Serum calprotectin and amyloid A represent novel candidate biomarkers of inflammatory activity in CG (see Visual Abstract, Supplementary Digital Content 4, http://links.lww.com/CTG/A349).

- Background:Abdominal pain is a common cause of visits to emergency facilities. It is related to psychiatric disorders in primary care, but it is unclear if this also holds in emergency departments. Objective:Is to explore potential differences between diagnostic groups in patients with acute abdominal pain in an emergency ward regarding concurrent somatic-and psychiatric symptoms, 'Length of stay' (LOS) and perceived health. Method:The patients (N = 137) were divided into three groups; organic dyspepsia, specific abdominal diagnoses, and non-specific abdominal pain. The Prime-MD results for extra gastrointestinal symptoms (outside the gastrointestinal tract), psychiatric symptoms, frequency of symptoms, self-reported health, and LOS within the month before admittance were compared between the diagnostic groups. Results: There was a significant positive correlation between the number of physical extra gastrointestinal and psychiatric symptoms (p < .001), especially regarding anxiety (p < .001) and depression (p = .002). Patients with organic dyspepsia reported significantly more total (p = .016), extragastrointestinal (p = .026) (chest pain;p = .017, dizziness;p = .004, palpitations;p = .005, insomnia;p = .005 and worries;p = .001), and summarized anxiety and depression symptoms (p = .001-0.002) besides poorer general health (p < .001) compared to other abdominal conditions. Also, organic dyspepsia patients needed longer hospital stay than the non-specific abdominal group (p = .002) but similar to the specific abdominal disorders group. Conclusion:Organic dyspepsia is accompanied by more co-occurring physical, anxiety and depression symptoms as well as poorer perceived health than other abdominal pain conditions and comparably increased LOS. This suggests that psychiatric consultations might be beneficial for diagnosing and treating psychiatric comorbidity in emergency care.

- Endoscopy with histopathological assessment is an established practice to confirm gastrointestinal graft-versus-host disease (GI-GVHD). However, the clinical relevance of this approach in children is incompletely evaluated. In a retrospective cohort study, we investigated the frequency of treatment changes in response to histopathological findings in all children (<18 years) in Sweden who underwent endoscopy for suspected GI-GVHD (2000-2013) after receiving hematopoietic stem cell transplantation. Sixty-eight children with ninety-one endoscopic occasions were enrolled. At the time of endoscopy, anti-GI-GVHD treatment was ongoing in 71% (65/91). In 18% (12/65) with ongoing treatment, no histopathological evidence of GI-GVHD or another cause to justify anti-GI-GVHD treatment was found. In 48% (44/91), endoscopy with histopathological assessment led to changes in the treatment regimen. Re-endoscopy was more frequent among those with treatment changes, versus unchanged treatment, 39% (17/44) and 13% (6/47), respectively (P = .007). Histopathological findings generating treatment changes were as follows: GI-GVHD in 68% (30/44), normal histology in 25% (11/44), and an alternative diagnosis in 7% (3/44). In conclusion, this study supports that endoscopy with histopathological assessment should be considered in all children with suspected GI-GVHD.

- The gut microbiome has a fundamental role in human health and disease. However, studying the complex structure and function of the gut microbiome using next generation sequencing is challenging and prone to reproducibility problems. Here, we obtained cross-sectional colon biopsies and faecal samples from nine participants in our COLSCREEN study and sequenced them in high coverage using Illumina pair-end shotgun (for faecal samples) and IonTorrent 16S (for paired feces and colon biopsies) technologies. The metagenomes consisted of between 47 and 92 million reads per sample and the targeted sequencing covered more than 300 k reads per sample across seven hypervariable regions of the 16S gene. Our data is freely available and coupled with code for the presented metagenomic analysis using up-to-date bioinformatics algorithms. These results will add up to the informed insights into designing comprehensive microbiome analysis and also provide data for further testing for unambiguous gut microbiome analysis.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Prevalence studies demonstrate that a significant proportion of lithium-treated patients develop hypercalcaemia (3-30%). Lithium-associated hyperparathyroidism (LHPT) is poorly defined, and calcium homeostasis may be affected in a more complicated fashion than purely by elevated PTH secretion. The current study aims to examine in detail calcium homeostasis principally with regard to lithium duration.METHODS: Medical records of 297 lithium-treated patients (193 women, 104 men; median age 58 years) were examined, and information on gender, age, lithium treatment duration and calcium homeostasis was obtained. The median treatment duration with lithium was 16 (1.5-45) years.RESULTS: A total of 8504 calcium values were retrieved. Before initiation of lithium treatment, serum calcium was on average 2.33 mmol/l (2.02-2.60). During the treatment period, 178 patients (60%) remained normocalcaemic, 102 (34%) developed hypercalcaemia or were strongly suspected of LHPT, 17 (6%) had 3 or more intermittent episodes of hypocalcaemia. Forty-one per cent of patients with suspected or confirmed LHPT had low (<4 mmol) 24-h urine calcium levels. The success rate after 33 parathyroidectomies was 35%, hyperplasia being diagnosed in 75% of extirpated glands.CONCLUSIONS: The prevalence of hypercalcaemia during lithium treatment is very high. In addition, hypocalcaemic episodes appear to occur frequently, possibly reflecting a more complicated parathyroid dysfunction than previously known. Long-term surgical results are unsatisfactory. LHPT biochemical profile is different from that of primary hyperparathyroidism and is in some ways similar to familial hypocalciuric hypercalcaemia.

- BACKGROUND AND AIMS: The only treatment for celiac disease is strict adherence to a gluten-free diet (GFD). We performed a systematic review to investigate the rate of adherence to a GFD in children with celiac disease, risk factors that affect adherence, and outcomes of non-adherence.METHODS: We searched PubMed, Cochrane Library, EBSCO, and Scopus for studies through January 2019. We included observational studies of ≥50 children diagnosed with celiac disease and recommended for placement on a GFD. We collected data on adherence assessment (self-report, serology tests, structured dietary interview, biopsies, or assays for gluten immunogenic peptides), risk factors, and outcomes related to adherence. Findings were presented with medians, range, and a narrative synthesis.RESULTS: We identified 703 studies; of these, 167 were eligible for full-text assessment and 49 were included in the final analysis, comprising 7850 children. Rates of adherence to a GFD ranged from 23% to 98%. Comparable rates (median rates of adherence, 75%-87%) were found irrespective of how assessments were performed. Adolescents were at risk of non-adherence and children whose parents had good knowledge about celiac disease adhered more strictly. Non-adherence associated with patient growth, symptoms, and quality of life.CONCLUSION: In a systematic review of 49 studies of children with celiac disease, we found substantial variation in adherence to a GFD among patients. Rate of adherence was not associated with method of adherence measurement, so all methods appear to be useful, with lack of consensus on the ideal metric. Studies are needed to determine the best method to ensure adherence and effects on long-term health.

Tidskriftsartikel (refereegranskat)abstract
- Background: No previous paediatric study has evaluated the frequency of diagnostic disagreement between clinical standard histopathological assessment (CSHA) and retrospective, independent, histopathological assessment (RIHA) of gastrointestinal Graft-Versus-Host Disease (GI-GVHD).Methods: In a retrospective cohort study, based on gastrointestinal biopsies collected from allogeneic HSCT-treated children (<18 years) with symptom-based GI-GVHD, we evaluated; disagreement of histopathology-based GI-GVHD diagnosis in CSHA vs RIHA, and potential clinical consequences of differences between the assessments. The CSHA-based diagnoses were retrieved from histopathology reports. The RIHA was performed by one pathologist, blinded to the CSHA outcomes and based on the minimal criteria for histopathology-based GI-GVHD diagnosis by theNIH 2014.Results: Seventy children with 92 endoscopic occasions (including 22 re-endoscopies) were enrolled. GI-GVHD was observed in 73% (67/92) of the endoscopies in the RIHA and in 54% (50/92) in the CSHA (P = .014). The RIHA confirmed 94% (47/50) with GI-GVHD and 52% (22/42) with non-GI-GVHD diagnoses, established in the CSHA. Disagreement, that is endoscopic occasions with GI-GVHD solely detected in RIHA or detection of GI-GVHD in CSHA but not in RIHA, was observed in 20/42 (48%) and 3/50 (6%), respectively (McNemar's test, P = .0008). The risk of a subsequent re-endoscopy was higher in endoscopic occasions with GI-GVHD detected in RIHA but not in CSHA vs if non-GI-GVHD were detected in both readings (P = .005).Conclusion: Our results suggest that in children with symptom-based GI-GVHD without histopathological confirmation in CSHA, a second,NIH 2014based histopathological assessment should be considered before performing a re-endoscopy.

Exploring the Biopsychosocial Model in Irritable Bowel Syndrome : with emphasis on stress, comorbidities and fatigue
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- BackgroundIrritable bowel syndrome (IBS) is a common, chronic, relapsing, and sometimes disabling, symptombased disorder of gut brain interactions. It has got a female predominance and occurs in all ages, with a slight decrease among elderly. The IBS symptoms can affect everyday work and social life in addition to an increased use of health care resources. Most IBS patients are diagnosed and helped in primary health care (PHC). For many patients, available treatment is insufficient. It is known that both extraintestinal symptoms such as fatigue, as well as comorbidities such as mood disorders, chronic pain syndromes, and insomnia contribute to the illness burden, often to a larger extent than the gastrointestinal symptoms as such.Even though the pathophysiology of IBS is not completely known, it is now conceptualized as a disorder of altered brain-gut interactions, where a biopsychosocial model helps in understanding the symptoms. Exposure to stress is thought to play an important role overall in the pathology of IBS, as well as immune activation at least in a subgroup of patients.This thesis aimed to gain deeper understanding of the biopsychosocial mechanisms of IBS and its associations with stress, comorbidities, and fatigue.Methods Study I and II are based on the Twin cities IBS study population, which included IBS patients and a control group of other patients without gastrointestinal complaints from ten PHC centres in the county of Östergötland. Alongside demographics, psychosocial questionnaires and a GI symptom diary, it included analyses of hair cortisol concentrations (HCC) evaluated in study I, and data on self-rated health as well as diagnoses of comorbidities, and number of health care contacts from a regional registry, evaluated for study II.Study III of this thesis is based on the Brain-Gut study with a population of secondary care IBS patients, and healthy controls (HC). It included self-rated measures of fatigue impact on the daily life and early adverse life events, as well as measures of circulating TNF-α, and analyses of resting-state functional magnetic resonance imaging of brain areas within a mesocorticolimbic circuitry of known relevance for fatigue.Results Study I: Perceived stress was higher in the IBS group while a considerable portion of IBS patients had low levels of HCC. No association between perceived stress and HCC was seen in either group.Study II: IBS patients had lower self-rated health and more PHC utilization than the non-IBS patients. Good self-rated health was independently associated with younger age, higher sense of coherence and less gastrointestinal pain in both groups. In IBS, PHC utilization was associated with comorbidities in general, and sleep disorders in particular.Study III: Fatigue impact on daily life, and TNF- α were higher in IBS patients than in HC. In IBS, further an association was seen between fatigue impact on the one hand, and TNF- α, emotional abuse in childhood, as well as altered mesocorticolimbic connectivity on the other.Conclusion In conclusion this thesis firstly emphasizes that IBS patients in many ways, including health outcomes, consists a vulnerable group of PHC patients. We add evidence for a possible suppression of the stress response system in a substantial portion of IBS patients.Further, comorbid sleep disorders seem to be particularly associated with excess PHC utilization in IBS and could possibly be a target for treatment interventions. Moreover, alongside treating gastrointestinal pain, efforts to improve the individuals’ sense of coherence could be one way to achieve better self-rated health in both IBS and non-IBS patients.Finally, we suggest that fatigue in IBS is associated with immune activation, central alterations and to some extend also previous childhood trauma.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this study was to compare the use and short-term outcome of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in Sweden, Norway, and the Netherlands. Background: Although bariatric surgery is performed in high volumes worldwide, no consensus exists regarding the choice of bariatric procedure for specific groups of patients. Methods: Data from 3 national registries for bariatric surgery were used. Patient selection, perioperative data (severe complications, mortality, and rate of readmissions within 30 days), and 1-year results (follow-up rate and weight loss) were studied. Results: A total of 47,101 primary operations were registered, 33,029 (70.1%) RYGB and 14,072 (29.9%) SG. Patients receiving RYGB met international guidelines for having bariatric surgery more often than those receiving SG (91.9% vs 83,0%,P< 0.001). The 2 procedures did not differ in the rate of severe complications (2.6% vs 2.4%,P= 0.382), nor 30-day mortality (0.04% vs 0.03%,P= 0.821). Readmission rates were higher after RYGB (4.3% vs 3.4%,P< 0.001). One-year post surgery, less RYGB-patients were lost-to follow-up (12.1% vs 16.5%,P< 0.001) and RYGB resulted in a higher rate of patients with total weight loss of more than 20% (95.8% vs 84.6%,P< 0.001). While the weight-loss after RYGB was similar between hospitals, there was a great variation in weight loss after SG. Conclusion: This study reflects the pragmatic use and short-term outcome of RYGB and SG in 3 countries in North-Western Europe. Both procedures were safe, with RYGB having higher weight loss and follow-up rates at the cost of a slightly higher 30-day readmission rate.
