The diagnosis of gastrointestinal graft versus host disease (GI-GVHD) is based on clinical symptoms and histological findings. In clinical practice, it is often difficult to decide whether abdominal symptoms in an allogeneic transplant recipient are caused by GVHD or other disorders. Endoscopic biopsies are helpful in establishing the diagnosis, but endoscopy is not always possible to perform due to poor general condition of the patients. No biomarkers are routinely used to predict GVHD. The aim of fecal calprotectin and alpha-1 antitrypsin testing in our study was to find out whether determination of the concentrations of these proteins may be used as a screening method for enteric GVHD. We studied prospectively 51 patients, 8 of whom developed GI-GVHD. Our data demonstrate that elevated fecal calprotectin levels were significantly associated with presence of GI-GVHD. We found a positive association between high F-calprotectin and severe gastrointestinal GVHD. In bivariate analysis, only calprotectin but not alpha-1 antitrypsin was independently associated with GI-GVHD. Testing for fecal calprotectin after allogeneic stem cell transplantation may be a useful screening tool

Efficacy and safety of mycophenolate mofetil and tacrolimus as second-line therapy for patients with autoimmune hepatitis

Background: Predniso(lo)ne, alone or in combination with azathioprine, is the standard of care (SOC) therapy for autoimmune hepatitis (AIH). However, the SOC therapy is poorly tolerated or does not control disease activity in up to 20% of patients. We assessed the efficacy of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy for patients with AIH. Patients and methods: We performed a retrospective study of data (from 19 centres in Europe, the United States, Canada, and China) from 201 patients with AIH who received second-line therapy (121 received MMF and 80 received tacrolimus), for a median of 62 months (range, 6–190 months). Patients were categorized according to their response to SOC. Patients in group 1 (n=108) had a complete response to the SOC, but were switched to second line therapy due to side effects of predniso(lo)ne or azathioprine, whereas patients in group 2 (n=93) had not responded to SOC. Results: There was no significant difference in the proportion of patients with a complete response to MMF (69.4%) vs tacrolimus (72.5%) (P=.639). In group 1, MMF and tacrolimus maintained a biochemical remission in 91.9% and 94.1% of patients, respectively (P=.682). Significantly more group 2 patients given tacrolimus compared to MMF had a complete response (56.5 % vs. 34%, P=.029) There were similar proportions of liver-related deaths or liver transplantation among patients given MMF (13.2%) vs tacrolimus (10.3%) (log-rank, P=.472). Ten patients receiving MMF (8.3%) and 10 patients receiving tacrolimus (12.5%) developed side effects that required therapy withdrawal. Conclusions: Long-term therapy with MMF or tacrolimus was generally well tolerated by patients with AIH. The agents were equally effective in previous complete responders who did not tolerate SOC therapy. Tacrolimus led to a complete response in a greater proportion of previous non-responder patients compared to MMF

Circulating Osteopontin and Prediction of Hepatocellular Carcinoma Development in a Large European Population.

We previously identified osteopontin (OPN) as a promising marker for the early detection of hepatocellular carcinoma (HCC). In this study, we investigated the association between prediagnostic circulating OPN levels and HCC incidence in a large population-based cohort. A nested case-control study was conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. During a mean follow-up of 4.8 years, 100 HCC cases were identified. Each case was matched to two controls and OPN levels were measured in baseline plasma samples. Viral hepatitis, liver function, and α-fetoprotein (AFP) tests were also conducted. Conditional logistic regression models were used to calculate multivariable odds ratio (OR) and 95% confidence intervals (95% CI) for OPN levels in relation to HCC. Receiver operating characteristics curves were constructed to determine the discriminatory accuracy of OPN alone or in combination with other liver biomarkers in the prediction of HCC. OPN levels were positively associated with HCC risk (per 10% increment, ORmultivariable = 1.30; 95% CI, 1.14-1.48). The association was stronger among cases diagnosed within 2 years of follow-up. Adding liver function tests to OPN improved the discriminatory performance for subjects who developed HCC (AUC = 0.86). For cases diagnosed within 2 years, the combination of OPN and AFP was best able to predict HCC risk (AUC = 0.88). The best predictive model for HCC in this low-risk population is OPN in combination with liver function tests. Within 2 years of diagnosis, the combination of OPN and AFP best predicted HCC development, suggesting that measuring OPN and AFP could identify high-risk groups independently of a liver disease diagnosis.

Association between physical activity and risk of hepatobiliary cancers : A multinational cohort study

Background & Aims: To date, evidence on the association between physical activity and risk of hepatobiliary cancers has been inconclusive. Weexamined this association in the European Prospective Investigation into Cancer and Nutrition cohort (EPIC). Methods: We identified 275 hepatocellular carcinoma (HCC) cases, 93 intrahepatic bile duct cancers (IHBCs), and 164 non-gallbladder extrahepatic bile duct cancers (NGBCs) among 467,336 EPIC participants (median follow-up 14.9 years). We estimated cause-specific hazard ratios (HRs) for total physical activity and vigorous physical activity and performed mediation analysis and secondary analyses to assess robustness to confounding (e.g. due to hepatitis virus infection). Results: In the EPIC cohort, the multivariable-adjusted HR of HCC was 0.55 (95% CI 0.38-0.80) comparing active and inactive individuals. Regarding vigorous physical activity, for those reporting >2 hours/week compared to those with no vigorous activity, the HR for HCC was 0.50 (95% CI 0.33-0.76). Estimates were similar in sensitivity analyses for confounding. Total and vigorous physical activity were unrelated to IHBC and NGBC. In mediation analysis, waist circumference explained about 40% and body mass index 30% of the overall association of total physical activity and HCC. Conclusions: These findings suggest an inverse association between physical activity and risk of HCC, which is potentially mediated by obesity. Lay summary: In a pan-European study of 467,336 men and women, we found that physical activity is associated with a reduced risk of developing liver cancers over the next decade. This risk was independent of other liver cancer risk factors, and did not vary by age, gender, smoking status, body weight, and alcohol consumption.

Autoimmune hepatitis in Sweden

Autoimmune hepatitis (AIH) was identified as an entity by the Swedish professor Jan Waldenström in the 1950s. It was then denoted lupoid hepatitis, characterized by liver inflammation and most often affecting young women. During the years the diagnosis has become more defined (as the non A non B hepatitis has been identified as Hepatitis C) and now can be safely separated from other diseases with liver inflammation. Studies of epidemiological data and long term prognosis have been scarce in the literature. Within a collaboration between the university hospitals in Sweden, we collected what we believe is the largest cohort in the world of patients with AIH. Data from the medical records of 473 individuals was, after AIH-score calculations where the diagnosis was confirmed, collected in a data base, in which most of the analysis was done. Data from the Swedish national registers of cancer, death cause, and birth register was searched for these patients as well as controls. The aim of the thesis was to explore epidemiological and clinical outcome of AIH.The onset of AIH may be at any age, but the incidence seems to increase after 50 years of age; 75% are females, the overall incidence (0.85/ 100,000 inhabitants and year) and prevalence (11/100,000 inhabitants) are figures that are within the range of another but smaller Scandinavian study. Approximately 30 % had cirrhosis already at diagnosis and 87% displayed at some time positive auto-antibodies indicating AIH (Smooth muscle ab and or antinuclear ab).  Indications of future risk for liver transplantation or death is an advanced AIH at diagnosis with liver cirrhosis, decompensated liver disease, elevated PK INR as well as age. Acute hepatitis-like onset seems to carry a lower risk for later liver transplantation or death. Current Swedish national therapy traditions with immune suppression seem to be well tolerated. Five and ten years overall life expectancy does not differ from controls. Thirty-five women gave birth to 63 children, for 3 after liver transplantation of the mother. Thirteen of the women had liver cirrhosis. Current pharmacological treatment seems to be safe both for the patient and the foetus. Thirty percent of the patients experienced flair after delivery. It has been supposed that there is an overrisk for hepatocellular cancer (HCC) associated with AIH. Our figures are the first in the world to be presented that confirms a twenty-three fold overrisk (95% Confidence Interval 7.5-54.3) for hepatobiliar cancer. We found as well an overrisk of non-Hodgkin lymphomas of 13.09 (95% CI 4.2-30.6).Conclusion:  Our epidemiological results confirm that AIH is a fairly uncommon disease, and that many already at time of diagnosis have an advanced disease with liver cirrhosis. There is a clear overrisk for HCC and lymphoma. For those women with AIH who become pregnant the prognosis for the child as well as for the mother is good, even for those women who already have compensated cirrhosis. There is a risk for relapse after delivery. The overall survival for AIH patients with current therapy is good

Self-monitoring with home based fecal calprotectin is associated with increased medical treatment : A randomized controlled trial on patients with inflammatory bowel disease

Objectives: 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. Materials and methods: 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. Results: 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. Conclusion: 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

The drug-survival of low-dose thioguanine in patients with inflammatory bowel disease : a retrospective observational study

Background: 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. Objectives: We studied drug-survival of low dose of thioguanine in real-life clinical practice in comparison to conventional thiopurines. Design: Retrospective observational study. Methods: 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. Results: 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 versus azathioprine p = 0.014; thioguanine versus 6-mercaptopurine (6-MP) p < 0.001]. For second-line thiopurine treatment thioguanine had longer drug-survival than 6-MP (Mantel–Cox rank test: p = 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 (p = 0.022). The median 6-thioguanine nucleotide levels in patients treated with thioguanine was 364 pmol/8 × 108. 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 versus 109 µg/g; p = 0.023), but there was no significant difference in FC levels for thioguanine compared to azathioprine (50 versus 109 µg/g; p = 0.33). Conclusion: Treatment with a low dose of thioguanine is well-tolerated in patients with IBD and had a significantly higher drug-survival than conventional thiopurines

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. Results: 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 versus azathioprine p  = 0.014; thioguanine versus 6-mercaptopurine (6-MP) p  < 0.001]. For second-line thiopurine treatment thioguanine had longer drug-survival than 6-MP (Mantel–Cox rank test: p  = 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 ( p  = 0.022). The median 6-thioguanine nucleotide levels in patients treated with thioguanine was 364 pmol/8 × 10 8 .

Survival after first diagnosis of oesophageal or gastric varices in a single centre in northern Sweden : a retrospective study

Aim of the study: Oesophageal and gastric varices are well-known causes of morbidity and mortality in patientswith liver cirrhosis. The aim of this retrospective observational study was to analyse clinical characteristics andoutcomes for patients with oesophageal and gastric varices at Norrland’s University Hospital, Umeå, Sweden. Material and methods: Data from medical records were collected retrospectively from 246 patients with oesophageal and gastric varices between 2006 and 2019. Results: At the end of the study 60.1% of the patients had died at a median age of 69 years (range 26-95).Mortality of patients with gastro-oesophageal varices was significantly greater than that of the general population. Median survival from the time of variceal diagnosis was 59 months (confidence interval [CI] 95%:45-73 months). Five-year and 10-year cumulative survival rates in the entire cohort were 49.7% and 27.7%,respectively, with no sex-related differences. The highest mortality rate was seen in alcoholic cirrhosis with concomitant hepatitis. Mortality was higher in Child-Turcotte-Pugh (CTP) B and C compared to CTP A. Liver failureand liver cancer were the most common causes of death (43.8%). Thirty-one percent of the patients had avariceal haemorrhage. Eleven percent were subjected to liver transplantation, whereas 3.9% of the patients had beensubmitted to a transjugular intrahepatic portosystemic shunt (TIPS) procedure. Conclusions: Despite the latest therapeutic advances, the survival of patients with gastro-oesophageal varicesremains significantly reduced. All-cause mortality was significantly related to CTP class, aetiology, occurrence ofvariceal bleeding, whether variceal bleeding was the primary symptom and whether patients had undergoneliver transplantation or not.
