Self-monitoring of inflammatory bowel disease (IBD) with the assistant of telemedicine and home-based fecal calprotectin (FC) tests is evolving in the management of IBD. We performed a randomized ...controlled trial to investigate the compliance and effects of the model IBD-Home in patients with IBD.
Patients were randomized to IBD-Home + standard care (n = 84) or standard care alone (n = 74). Intervention with IBD-Home included IBDoc
®
FC test kits and a digital application used for answering symptom questionnaires (Abbvie/Telia). They were instructed to use these on demand during a 12-month period. Data was collected retrospectively from medical records. Patients who completed the intervention were phoned and asked to answer a survey about the experience of IBD-Home.
The compliance to IBD-Home was low (29%). Women were more compliant compared with men (43% vs 17%, p < .001). A significantly higher proportion of patients in the IBD-Home group increased their medical treatment during the study period in comparison to control subjects (33% vs 15% p = .007) and there was an association between an increase in treatment and compliance to IBD home (multivariate odds ratio 3.22; 95
th
confidence interval 1.04 − 9.95). Overall patients reported a positive experience with slight technical difficulties.
Self-monitoring with home based fecal calprotectin and a digital application was found feasible and appreciated by compliers. Compliance to the IBD-Home model was more common in women and associated with an increased treatment for IBD.
Thiopurines are commonly used to treat inflammatory bowel disease but withdrawal due to side effects are common. Thioguanine has been suggested to be better tolerated than conventional thiopurines.
...We studied drug-survival of low dose of thioguanine in real-life clinical practice in comparison to conventional thiopurines.
Retrospective observational study.
All patients born 1956 and later, and who at least once started thiopurine treatment between 2006 and 2022 were included. A medical chart review was performed that noted drug-survival for every thiopurine treatment attempt. The Mantel-Cox rank test was used to test differences in drug-survival for different thiopurines. Blood chemistry analysis and faecal calprotectin levels were registered for the first 5 years of treatment.
In the study population, there was 379 initiated thiopurine treatments (210 for Crohn's disease and 169 for ulcerative colitis) in 307 patients with inflammatory bowel disease (IBD). Low-dose thioguanine (median dose 11 mg; 25-75th percentile 7-19 mg) had been initiated in 31 patients. Overall, when including all thiopurine attempts, thioguanine had the longest drug-survival Mantel-Cox rank test: thioguanine
azathioprine
= 0.014; thioguanine
6-mercaptopurine (6-MP)
< 0.001. For second-line thiopurine treatment thioguanine had longer drug-survival than 6-MP (Mantel-Cox rank test:
= 0.006). At 60 months, 86% of the patients who started low-dose thioguanine were still on treatment compared to 42% of the patients who started 6-MP (
= 0.022). The median 6-thioguanine nucleotide levels in patients treated with thioguanine was 364 pmol/8 × 10
. Patients on thioguanine treatment showed significantly lower values of median mean corpuscular volume at follow-up than patients treated with azathioprine and 6-MP. Patients treated with 6-MP showed significantly lower levels of FC in the third year of treatment compared to patient treated with azathioprine (59
109 µg/g;
= 0.023), but there was no significant difference in FC levels for thioguanine compared to azathioprine (50
109 µg/g;
= 0.33).
Treatment with a low dose of thioguanine is well-tolerated in patients with IBD and had a significantly higher drug-survival than conventional thiopurines.
The evidence for hepatobiliary tumour surveillance in patients with primary sclerosing cholangitis (PSC) is scarce. In this study, we aimed to prospectively evaluate cholangiocarcinoma (CCA) ...surveillance with yearly MRI with cholangiopancreatography (MRI/MRCP) in a nationwide cohort.
In total, 512 patients with PSC from 11 Swedish hospitals were recruited. The study protocol included yearly clinical follow-ups, liver function tests and contrast-enhanced MRI/MRCP and carbohydrate antigen (CA) 19-9. Patients with severe/progressive bile duct changes on MRI/MRCP were further investigated with endoscopic retrograde cholangiopancreatography. Patients were followed for 5 years or until a diagnosis of CCA, liver transplantation (LT) and/or death. Risk factors associated with CCA were analysed with Cox regression.
Eleven patients (2%) were diagnosed with CCA, and two (0.5%) with high-grade bile duct dysplasia. Severe/progressive bile duct changes on MRI/MRCP were detected in 122 patients (24%), of whom 10% had an underlying malignancy. The primary indication for LT (n = 54) was biliary dysplasia in nine patients (17%) and end-stage liver disease in 45 patients (83%), of whom three patients (7%) had unexpected malignancy in the explants. The median survival for patients with CCA was 13 months (3-22 months). Time to diagnosis of high-grade dysplasia and/or hepatobiliary malignancy was significantly associated with severe/progressive bile duct changes on MRI/MRCP (hazard ratio 10.50; 95% CI 2.49-44.31) and increased levels of CA19-9 (hazard ratio 1.00; 95% CI 1.00-1.01).
In an unselected cohort of patients with PSC, yearly CA19-9 and MRI/MRCP surveillance followed by ERCP was ineffective in detecting cancer early enough to support long-term survival. Given the low occurrence of CCA, studies on individualised strategies for follow-up and improved diagnostic methods for PSC-related CCA are warranted.
A prospective nationwide 5-year study was conducted to evaluate yearly cholangiocarcinoma surveillance using MRI and CA19-9 in patients with primary sclerosing cholangitis. Only 2% of the patients were diagnosed with cholangiocarcinoma during follow-up and their prognosis remained poor despite surveillance. This surveillance strategy failed to detect cancer early enough to support long-term survival. Therefore, individualised strategies and improved diagnostic methods will be required to improve the early detection of cholangiocarcinoma in patients with primary sclerosing cholangitis.

Summary
This study aimed to investigate the significance of Hill classification to predict esophagitis, Barrett’s esophagus, gastroesophageal reflux disease (GERD) symptomatology, and future ...prescriptions of proton pump inhibitors in clinical practice. A total of 922 patients (546 women and 376 men; mean age 54.3 SD 18.4 years) who underwent gastroscopy between 2012 and 2015 were analyzed. Patient questionnaire regarding symptoms were compared with endoscopy findings. A medical chart review was done that focused on the prescription of PPIs, additional gastroscopies, and GERD surgery in a 3-year period before the index gastroscopy and in a 6-year period afterward. In patients naïve to PPI prescriptions (n = 466), Hill grade III was significantly associated with esophagitis (AOR 2.20; 95% CI 1.00–4.84) and > 2 PPI prescriptions 6 year after the index gastroscopy (AOR 1.95; 95% CI 1.01–3.75), whereas Hill grade IV was significantly associated with esophagitis (AOR 4.41; 95% CI 1.92–10.1), with Barrett’s esophagus (AOR 12.7; 95% CI 1.45–112), with reported heartburn (AOR 2.28; 95% CI 1.10–4.74), and with >2 PPI prescriptions (AOR 2.16; 95% CI 1.02–4.55). In patients ‘non-naïve’ to PPI prescription (n = 556), only Hill grade IV was significantly associated with esophagitis, reported heartburn, and with >2 PPI prescriptions. The gastroscopic classification in Hill grades III and IV is important in clinical practice because they are associated with esophagitis, Barrett’s esophagus, symptoms of GERD, and prescriptions of PPIs, whereas a differentiation between Hill grades I and II is not.
Abstract Aims To compare Alcohol Use Disorders Identification Test (AUDIT C) to phosphatidylethanol (PEth) in middle-aged randomly selected volunteers. Apply previously suggested lower cut-offs for ...PEth using moderate alcohol intake according to AUDIT C as a reference. Methods Within the Swedish CardioPulmonary BioImage Study, 2255 middle-aged (50–64 years of age) volunteers in northern Sweden participated in comparing AUDIT C to PEth 16:0/18:1. Results There was a moderate correlation between PEth 16:0/18:1 and AUDIT C (r = 0.66). None of the participants with the AUDIT C-score 0 had a measurable PEth. Of moderate alcohol consumers, according to AUDIT C (AUDIT C 1–3 women, 1–4 men), 96% had a PEth below 0.3 μmol/L, 91% had a PEth below 0.16 μmol/L, and 84% had a PEth below 0.11 μmol/L. With PEth equivalent to excessive alcohol consumption (≥0.3 μmol/L), 26% had an AUDIT C-score below excessive alcohol consumption (<4 for women and <5 for men). Thirty percent of patients with a PEth ≥0.16 μmol/L had an AUDIT C-score below excessive alcohol consumption, and 37% had a PEth ≥0.11 μmol/L. We found no significant correlation between BMI and PEth or AUDIT C. Conclusions There is a significant correlation between AUDIT C and PEth. Using AUDIT C alone, 26% of high-consumers, according to PEth, are not found in our cohort, but an AUDIT C-score of 0 will exclude high consumption, according to PEth. Our findings support the current cut-off for PEth of 0.3 μmol/L, but a lower cut-off seems reasonable.
Primary biliary cholangitis (PBC) is an autoimmune liver disease that may progress into liver cirrhosis. Ursodeoxycholic acid (UDCA) is known to prevent or delay the disease progression, but little ...is known about work incapacity in PBC patients. We aimed to compare clinical outcomes (transplantation-free survival; cirrhosis development) and sick leave in patients with PBC with and without UDCA therapy.
The medical records of 526 patients with PBC diagnosed from 2004 to 2016 were reviewed retrospectively. Sick leave data retrieved from the Swedish Social Insurance Agency were analysed for a sub-cohort of patients and matched controls. Cox regression was used for analysis of clinical outcomes. Logistic and conditional logistic regressions were used for sick leave analysis.
A total of 10.6% of patients died and 3.4% received liver transplantation over a median follow-up time of 5.7 years. UDCA-untreated patients (HR 3.62 (95%CI 2.02-6.49)) and UDCA non-responders (HR 3.78 (95% CI 1.87-7.66)) had higher mortality or transplantation rates than UDCA responders. Patients with PBC had higher odds of sick leave (OR 2.50; 95% CI 1.69-3.70) than matched controls. Untreated patients were more likely to be on sick leave (OR 3.22; 95% CI 1.12-9.25) two years after diagnosis than UDCA responders.
Both untreated patients and UDCA non-responders had lower liver transplantation-free survival rates than UDCA responders. Patients with PBC were more likely to be on sick leave compared to matched controls from the general population.
Objective. Autoimmune hepatitis (AIH) is a chronic liver disease, which if untreated can lead to cirrhosis and hepatic failure. The aim of the study was to investigate the incidence, prevalence, ...diagnostic tradition and clinical initial presentation of AIH. Material and methods. Analyses were performed in 473 patients identified as having probable or definite AIH. Results. The incidence of AIH was 0.85/100,000 (95% CI 0.69-1.01) inhabitants, which is somewhat lower than reported previously. The point prevalence amounted to 10.7/100,000 (95% CI 8.8-13.1), and 76% of the cases were females. The age-related incidence curve was bimodal but men were found to have only one incidence peak in the late teens, whereas women had a peak after menopause. AIH was presented as a spectrum of clinical settings from detected "en passant" to acute liver failure. Almost 30% of patients already had liver cirrhosis at diagnosis. Autoantibodies indicative of AIH type 1 were found in 79% of cases. Other concomitant autoimmune diseases were frequently found (49%). Conclusions. The incidence and prevalence figures confirm that AIH is a fairly uncommon disease in the Swedish population. Symptoms at presentation were unspecific, but almost half of the patients were jaundiced, with around 30% having liver cirrhosis. The majority of Swedish AIH patients had AIH type 1.
Background: Epidemiological studies of autoimmune hepatitis (AIH) show varying figures on prevalence and incidence, and data on the long-term prognosis are scarce.
Objective To investigate the ...epidemiology, long-term prognosis and causes of death in a Swedish AIH cohort.
Material and methods: Data collected from 634 AIH patients were matched to the Cause of Death Registry, and survival analyses were made. Prevalence and incidence were calculated for university hospitals with full coverage of cases and compared to the County of Västerbotten in Northern Sweden.
Results: AIH point prevalence was 17.3/100,000 inhabitants in 2009, and the yearly incidence 1990-2009 was 1.2/100,000 inhabitants and year. The time between diagnosis and end of follow-up, liver transplantation or death was in median 11.3 years (range 0-51.5 years). Men were diagnosed earlier (p < .001) and died younger than women (p = .002). No gender differences were found concerning transplant-free, overall survival and liver-related death. Cirrhosis at diagnosis was linked to an inferior survival (p < .001). Liver-related death was the most common cause of death (32.7%). The relative survival started to diverge from the general population 4 years after diagnosis but a distinct decline was not observed until after more than 10 years.
Conclusions: Long-term survival was reduced in patients with AIH. No gender difference regarding prognosis was seen but men died younger, probably as a result of earlier onset of disease. Cirrhosis at diagnosis was a risk factor for poor prognosis and the overall risk of liver-related death was increased.
Background & Aims
Mutations in the HFE gene can lead to hereditary haemochromatosis (HH) and have been suggested to increase the risk of extra‐hepatic diseases, especially breast and colorectal ...cancer. Here we investigated long‐term outcomes of Swedish patients with HFE mutations.
Methods
We identified 3645 patients with a homozygous p.C282Y (62%) or a compound heterozygous p.C282Y/p.H63D (38%) mutation from eight centres in Sweden between 1997 and 2017. These were matched 1:10 by age, sex and county of residence to reference individuals from the general population. We ascertained incident outcomes until the end of 2017 by linkage to national registers. Studied outcomes were HH, cirrhosis, hepatocellular carcinoma (HCC), breast cancer (in women), colorectal cancer, type 1 and 2 diabetes, hypothyroidism, Parkinson’s disease and mortality. Cox proportional hazards regression was used to estimate hazard ratios for these outcomes.
Results
Median age at diagnosis was 52 years, 44% were females. During a mean follow‐up of 7.9 years, we found an increased risk for HCC, HH, cirrhosis, type 2 diabetes, osteoarthritis and death. Excess mortality was only seen in men. No increased risk was seen for colorectal or breast cancer. Liver‐related outcomes were rare, with a cumulative incidence of <1%.
Conclusions
Individuals found to be HFE mutation carriers in a university hospital setting had an increased risk for mortality in men, along with increased risks of cirrhosis, HCC, diabetes type 2, and osteoarthritis. In general, the absolute risk for adverse outcomes was low and no increased risk for colon or breast cancer was observed.

Background:
Adrenal insufficiency (AI) secondary to treatment with glucocorticoids (GCs) is common in patients with inflammatory bowel disease (IBD), but little is known about the relationship ...between AI and the clinical course in IBD. The aim of the study was to compare the clinical course in IBD patients with normal adrenal function versus patients with subnormal adrenal function.
Methods:
A retrospective observational study on 63 patients with IBD who had performed a low-dose short Synacthen test (LDSST) (1 μg) immediately (1–7 days) after a standard course of GCs. A subnormal LDSST was defined as serum cortisol <550 nmol/L. Outcomes were time to next flare and fecal calprotectin levels.
Results:
Sixty-three percent (n = 40) of the IBD patients had a subnormal LDSST. Patients who were steroid-free (n = 41) after the LDSST were observed for 3 years. Patients with a peak serum cortisol <400 nmol/L immediately after GC treatment had significantly longer time until the next flare-up of their IBD and tended to use a lower cumulative prednisolone dose during the study period in comparison to the other subgroups. Fecal calprotectin levels were significantly lower in patients with a peak s-cortisol <550 nmol/L versus patients with peak s-cortisol ⩾550 nmol/L (median 336 µg/g (IQR 521) versus 955 µg/g (IQR 1867); p = 0.012).
Conclusions:
GC-induced AI is common in patients with IBD and is associated with lower disease activity. This suggests a link between responsiveness to GC treatment and suppression of the hypothalamic–pituitary–adrenal axis in IBD.
