Autoimmune liver diseases are associated with an increased risk of diabetes, yet the underlying mechanisms remain unknown.In this cross-sectional study, we investigated the glucose-regulatory disturbances in patients with autoimmune hepatitis (AIH, n ¼19), primary biliary cholangitis (PBC, n ¼ 15), and primary sclerosing cholangitis (PSC, n ¼ 6). Healthy individuals (n ¼ 24) andpatients with metabolic dysfunction-associated steatotic liver disease (MASLD, n ¼ 18) were included as controls. Blood sampleswere collected during a 120-min oral glucose tolerance test. We measured the concentrations of glucose, C-peptide, insulin, glu-cagon, and the two incretin hormones, glucose insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1). We calculatedthe homeostasis model assessment of insulin resistance (HOMA-IR), whole body insulin resistance (Matsuda index), insulin clear-ance, and insulinogenic index. All patient groups had increased fasting plasma glucose and impaired glucose responses com-pared with healthy controls. Beta-cell secretion was increased in AIH, PBC, and MASLD but not in PSC. Patients with AIH andMASLD had hyperglucagonemia and hepatic, as well as peripheral, insulin resistance and decreased insulin clearance, resultingin hyperinsulinemia. Patients with autoimmune liver disease had an increased GIP response, and those with AIH or PBC had anincreased GLP-1 response. Our data demonstrate that the mechanism underlying glucose disturbances in patients with autoim-mune liver disease differs from that underlying MASLD, including compensatory incretin responses in patients with autoimmuneliver disease. Our results suggest that glucose disturbances are present at an early stage of the disease.

Background & Aims Alcohol-related hepatitis (AH) and alcohol-related cirrhosis are grave conditions with poor prognoses. Altered hepatic lipid metabolism can impact disease development and varies between different alcohol-related liver diseases. Therefore, we aimed to investigate lipidomics and metabolomics at various stages of alcohol-related liver diseases and their correlation with survival. Methods Patients with newly diagnosed alcohol-related cirrhosis, who currently used alcohol (ALC-A), stable outpatients with decompensated alcohol-related cirrhosis with at least 8 weeks of alcohol abstinence (ALC), and patients with AH, were compared with each other and with healthy controls (HC). Circulating lipids and metabolites were analysed using HPLC and mass spectrometry. Results Forty patients with ALC, 95 with ALC-A, 30 with AH, and 42 HC provided plasma. Lipid levels changed according to disease severity, with generally lower levels in AH and cirrhosis than in the HC group; this was most pronounced for AH, followed by ALC-A. Nine out of 10 free fatty acids differed between cirrhosis groups by relative increases of 0.12–0.66 in ALC compared with the ALC-A group (p <0.0005). For metabolomics, total bile acids increased by 19.7, 31.3, and 80.4 in the ALC, ALC-A, and AH groups, respectively, compared with HC (all p <0.0001). Low sphingolipid ([d42:1] and [d41:1]) levels could not predict 180-day mortality (AUC = 0.73, p = 0.95 and AUC = 0.73, p = 0.95) more accurately than the model for end-stage liver disease score (AUC = 0.71), but did predict 90-day mortality (AUC d42:1 = 0.922, AUC d41:1 = 0.893; p d42:1 = 0.005, p d41:1 = 0.007) more accurately than the MELD score AUCMELD = 0.70, pMELD = 0.19).

Acute liver failure (ALF) is rare but life-threatening. Common causes include intoxications, infections, and metabolic disorders. Indeterminate etiology is still frequent. No systematic data on incidence, causes, and outcome of ALF across Europe are available. Via an online survey we reached out to European Reference Network Centers on rare liver diseases. Numbers and etiology of ALF cases during 2020 were retrieved and diagnostic and treatment availabilities assessed. In total, 455 cases (306 adult, 149 pediatric) were reported from 36 centers from 20 countries. Intoxication was the most common cause in adult and pediatric care. The number of cases with indeterminate etiology is low. Diagnostic tools and specific treatment options are broadly available within this network. This is the first approach to report on etiology and outcome of ALF in the pediatric and adult population in Europe. High diagnostic yield and standard of care reflects the expert status of involved centers.

Background: Elevated serum bile acids (BA) are harmful to the heart and alterations in the BA composition have been suggested to cause cardiovascular disturbances in cirrhosis. Aim: To investigate any associations between specific groups or individual serum BA and structural and functional cardiac abnormalities in patients with cirrhosis. Methods: An explorative study in 86 patients with cirrhosis. All participants underwent extensive cardiac assessment, including cardiac MRI with quantification of myocardial extracellular volume (ECV), which is indicative of diffuse myocardial fibrosis. A panel of 15 individual serum BA and C4, a marker of de novo bile acid synthesis, were assessed. Results: Patients with advanced cirrhosis had higher levels of total BA and conjugated BA, as well as lower C4 levels (p < 0.001). Conjugated BA levels were higher in patients with a high cardiac index (p < 0.001), increased left atrial volume index (LAVI) (p < 0.001), and in those with an abnormal myocardial ECV (p < 0.05). We also found several strong correlations between conjugated BA, both as a group and individually, and parameters of cardiac dysfunction. In a model adjusted for sex, age, BMI and MELD, conjugated BA remained significantly associated with LAVI, septal e′, left ventricular volumes and cardiac index. In addition, taurocholic acid correlated closely with hepatic venous pressure gradient (HVPG) (p = 0.01). Conclusions: Increased serum concentrations of conjugated BA are associated with several cardiac parameters, indicating a potential role in the development of hyperdynamic circulation and cardiac dysfunction in cirrhosis. Moreover, taurine-conjugated BA are associated with portal hypertension.

Background and Aims: Patients with some chronic liver diseases have increased risk of diabetes. Whether this is also the case for patients with autoimmune liver diseases is unknown. The study aimed to calculate risk and worldwide prevalence of diabetes in patients with autoimmune hepatitis (AIH), primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). Methods: We performed a case–control study using data from the United Kingdom Biobank (UKB) and compared frequency of type 1 diabetes (T1D) and type 2 diabetes (T2D) in AIH and PBC with age-, sex-, BMI- and ethnicity-matched controls. Next, we performed a systematic review and proportional meta-analysis searching PubMed, Embase, Cochrane Library and Web of Science (inception to 1 May 2022 [AIH]; 20 August 2022 [PBC]; 11 November 2022 [PSC]). The pooled prevalence of diabetes was calculated using an inverse method random effects model. Results: Three hundred twenty-eight AIH patients and 345 PBC patients were identified in UKB and risk of T1D and T2D significantly increased compared with matched controls. Our systematic search identified 6914 records including the UKB study. Of these, 77 studies were eligible for inclusion comprising 36 467, 39 924 and 4877 individuals with AIH, PBC and PSC, respectively. The pooled prevalence of T1D was 3.8% (2.6%–5.7%), 1.7% (0.9%–3.1%), 3.1% (1.9%–4.8%) and of T2D 14.8% (11.1%–19.5%), 18.1% (14.6%–22.2%), 6.3% (2.8%–13.3%) in patients with AIH, PBC and PSC, respectively. Conclusions: Patients with autoimmune liver diseases have increased risk of diabetes. Increased awareness of diabetes risk in patients with autoimmune liver diseases is warranted.

Autoimmune liver diseases include autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. They are chronic, heterogenous diseases affecting the liver which is a key metabolic organ that ensures glucose homeostasis. It is well known that patients with other chronic liver diseases such as cirrhosis and nonalcoholic fatty liver disease (NAFLD) display glucose disturbances like insulin resistance and have an increased risk of diabetes. Previous evidence on glucose disturbances in patients with autoimmune liver disease is scarce but does point towards a potentially increased risk of type 1 diabetes and type 2 diabetes. The underlying mechanisms are unknown but may reflect genetic predisposition, concurrent NAFLD and or cirrhosis development, and treatment (steroid) related impairment of glucose homeostasis. Therefore, increased awareness and surveillance of diabetes development in patients with autoimmune liver disease may be important. Overall, detection and treatment of diabetes generally follow the usual diabetes guidelines; however, in patients with advanced liver cirrhosis, HbA1c may not be a reliable marker of average glucose levels, and treatment with insulin is generally recommended. In addition, it has recently been suggested that sodium–glucose cotransporter 2 inhibitors may be beneficial in treating refractory ascites.

Background & Aims: Data on the management of primary sclerosing cholangitis (PSC) in European expert centres are sparse. In this study, a PSC group from the ERN RARE-LIVER surveyed European hepatologists to uncover differences in real-life clinical practices. Methods: In April 2020 a survey questionnaire was sent to members of the International PSC Study Group and ERN RARE-LIVER. Participants were asked about the size of their PSC cohort, use of medical treatments including ursodeoxycholic acid (UDCA) and surveillance for cholangiocarcinoma, gallbladder polyps and inflammatory bowel disease (IBD). Data were presented descriptively. Results: Eighty-two of 278 members responded. Fifty percent of physicians prescribed UDCA routinely to all their patients with PSC, whereas 12% never prescribed UDCA. UDCA was used for one or more indications including: alkaline phosphatase >1.5x the upper limit of normal, severe PSC changes, pruritus, PSC-IBD or patient demand. Few physicians offered other medical treatments than UDCA. The use of medical treatments was generally comparable in small (<99 patients) and large (≥99 patients) cohorts, as well as for adult and paediatric physicians. Most physicians routinely screened for cholangiocarcinoma and the most frequent modalities used were MRI and ultrasound. At detection of a gallbladder polyp of 6 mm, 46% of physicians recommended repeated ultrasound after 3-6 months, whereas 44% of physicians recommended immediate cholecystectomy. In patients with PSC without IBD at PSC diagnosis, 68% of physicians repeated colonoscopy within 3-5 years whereas 27% referred only patients who developed symptoms of IBD. Conclusion: Substantial variations in treatment and monitoring of European patients with PSC were discovered. Harmonisation of strategies is desirable to enable improved interpretation of outcome data and to optimise clinical patient care. Lay summary: In this study, we explored how different centres in Europe manage prima

Background and aimsAlcoholic hepatitis (AH) is characterized by acute liver failure, neurocognitive impairment and renal failure. Severe inflammatory reactions are also known to occur in AH. Inflammation and bacterial translocation in the gut are thought to have major impact on disease development and progression. The mortality rate for AH is close to 50%. We aimed to assess the efficacy of rifaximin in treating AH and its impact on inflammation and metabolism. MethodsThe trial was approved by relevant authorities (EudraCT no: 2014-02264-33, Scientific Ethics Committee, jr. no: H-1-2014-056). Primary outcomes were changes in metabolic and inflammatory markers. Secondary outcomes were portal hypertension, kidney and neurocognitive function. ResultsThirty-two patients were randomized to standard medical therapy (SMT) or SMT plus rifaximin, allocation was concealed. Four patients in the SMT group and five patients in the SMT + rifaximin group died due to AH and liver failure. No adverse events related to the study medication were observed. We found no significant differences in amino acids or inflammation markers (IL-2, IL-6, IL-8, IL-10, TNF-alpha, interferon-gamma) between the groups after 28 and 90 days. ConclusionRifaximin does not alter inflammation or metabolism in patients with AH.

Liver cirrhosis is a disease characterised by multiple complications and a poor prognosis. The prevalence is increasing worldwide. Chronic inflammation is ongoing in liver cirrhosis. No cure for the inflammation is available, and the current treatment of liver cirrhosis is only symptomatic. However, several different medical agents have been suggested as potential healing drugs. The majority are tested in rodents, but few human trials are effectuated. This review focuses on medical agents described in the literature with supposed alleviating and curing effects on liver cirrhosis. Twelve anti-inflammatory, five antioxidative, and three drugs with effects on gut microflora and the LPS pathway were found. Two drugs not categorised by the three former categories were found in addition. In total, 42 rodent studies and seven human trials were found. Promising effects of celecoxib, aspirin, curcumin, kahweol, pentoxifylline, diosmin, statins, emricasan, and silymarin were found in cirrhotic rodent models. Few indices of effects of etanercept, glycyrrhizin arginine salt, and mitoquinone were found. Faecal microbiota transplantation is in increasing searchlight with a supposed potential to alleviate cirrhosis. However, human trials are in demand to verify the findings in this review.

Serum microfibrillar-associated protein 4 (sMFAP4) has been investigated as a biomarker for various diseases and is demonstrated to show significant gradual increase with severity of liver fibrosis. Ideal biomarkers used for disease diagnosis or prognosis should display deviating levels in affected individuals only and be robust to factors unrelated to the disease. Here we show the impact of normal physiological variation of sMFAP4 by characterizing the circadian variation, week-to-week variation, and physical exercise-induced levels. Serum samples from 3 groups of healthy volunteers were drawn: 7 times during a 24-hour period, 5 times during a 3-week period, and before and after a standardized physical exercise challenge. sMFAP4 was determined by AlphaLISA. Statistical analysis was performed using mixed effects modeling of repeated measurements. Circadian variation of sMFAP4 was demonstrated, with time of peak and nadir values depending on age and gender. For males, the peak values were observed during nighttime whereas for females, peak values were observed in the morning. Individual sMFAP4 levels remained stable over a period of 3 weeks and physical exercise inferred a mild negative influence. In conclusion, the circadian sMFAP4 variation was significant, and the levels could be influenced by physical activity. However, these variations were of limited magnitude relative to previously observed disease-induced levels in support of the biomarker potential of sMFAP4.

Background & Aims: Gut-homing lymphocytes that express the integrin α4β7 and CCR9 might contribute to development of primary sclerosing cholangitis (PSC). Vedolizumab, which blocks the integrin α4β7, is used to treat patients with inflammatory bowel diseases (IBD), but there are few data on its efficacy in patients with PSC. We investigated the effects of vedolizumab in a large international cohort of patients with PSC and IBD. Methods: We collected data from European and North American centers participating in the International PSC Study Group from patients with PSC and IBD who received at least 3 doses of vedolizumab (n = 102; median vedolizumab treatment duration, 412 days). Demographic and clinical data were collected from baseline and during the follow-up period (until liver transplantation, death, or 56 days after the final vedolizumab infusion). We analyzed overall changes in biochemical features of liver and proportions of patients with reductions in serum levels of alkaline phosphatase (ALP) of 20% or more, from baseline through last follow-up evaluation. Other endpoints included response of IBD to treatment (improved, unchanged, or worsened, judged by the treating clinician, as well as endoscopic score) and liver-related outcomes. Results: In the entire cohort, the median serum level of ALP increased from 1.54-fold the upper limit of normal at baseline to 1.64-fold the upper limit of normal at the last follow-up examination (P =.018); serum levels of transaminases and bilirubin also increased by a small amount between baseline and the last follow-up examination. Serum levels of ALP decreased by 20% or more in 21 patients (20.6%); only the presence of cirrhosis (odds ratio, 4.48; P =.019) was independently associated with this outcome. Of patients with available endoscopic data, 56.8% had a response of IBD to treatment. Liver-related events occurred in 21 patients (20.6%), including bacterial cholangitis, cirrhosis decompensation, or transplantation.

BACKGROUND & AIMS: Few patients with primary sclerosing cholangitis (PSC) and inflammatory bowel diseases (IBDs) are exposed to tumor necrosis factor (TNF) antagonists because of the often mild symptoms of IBD. We assessed the effects of anti-TNF agents on liver function in patients with PSC and IBD, and their efficacy in treatment of IBD. METHODS: We performed a retrospective analysis of 141 patients with PSC and IBD receiving treatment with anti-TNF agents (infliximab or adalimumab) at 20 sites (mostly tertiary-care centers) in Europe and North America. We collected data on the serum level of alkaline phosphatase (ALP). IBD response was defined as either endoscopic response or, if no endoscopic data were available, clinical response, as determined by the treating clinician or measurements of fecal calprotectin. Remission was defined more stringently as endoscopic mucosal healing. We used linear regression analysis to identify factors associated significantly with level of ALP during anti-TNF therapy. RESULTS: Anti-TNF treatment produced a response of IBD in 48% of patients and remission of IBD in 23%. There was no difference in PSC symptom frequency before or after drug exposure. The most common reasons for anti-TNF discontinuation were primary nonresponse of IBD (17%) and side effects (18%). At 3 months, infliximab-treated patients had a median reduction in serum level of ALP of 4% (interquartile range, reduction of 25% to increase of 19%) compared with a median 15% reduction in ALP in adalimumab-treated patients (interquartile range, reduction of 29% to reduction of 4%; P = .035). Factors associated with lower ALP were normal ALP at baseline (P < .01), treatment with adalimumab (P = .090), and treatment in Europe (P = .083). CONCLUSIONS: In a retrospective analysis of 141 patients with PSC and IBD, anti-TNF agents were moderately effective and were not associated with exacerbation of PSC symptoms or specific side effects. Prospective studies are needed to

INTRODUCTION: Due to the coronavirus disease 2019 (COVID-19) exposure in Denmark, first-line referral centres were established to handle all patients suspected of COVID-19 or other upper respiratory tract infection. Here we report the first experiences from a first-line referral centre from Amager-Hvidovre Hospital, situated on the outskirts of Copenhagen.METHODS: A retrospective quality assessment was performed with collection of symptom patterns and COVID-19 status.RESULTS: During the first 24 days, a total of 3,551 patients were referred for assessment of symptoms of upper respiratory tract infection and COVID-19. A total of 2,048 patients were assessed as having mild symptoms and referred for COVID-19 testing alone, whereas 337 patients were assessed clinically by a physician. Thirty-seven were positive for COVID-19 infection, 286 were negative. The most common symptoms reported were fever, coughing and dyspnoea. Fever was an independent predictor of COVID-19 infection (odds ratio (OR) = 2.25 (95% confidence interval (CI): 1.08-5.04); p = 0.037); whereas sore throat was not (OR = 0.40 (95% CI: 0.15-0.92); p = 0.045). Only a small number of patients reported loss of taste or anosmia. In total, 113 patients were admitted to hospital, the majority of patients were discharged within 24 hours with mild symptoms of upper respiratory tract infections. Three of the COVID-19-positive patients developed a severe infection and two had a fatal outcome.CONCLUSIONS: The present study is the first to report the experiences and symptom patterns of a COVID-19 first-line referral centre with efficient triage of patients in need of hospitalisation.FUNDING: none.TRIAL REGISTRATION: not relevant.

INTRODUCTION: Risk stratification based on biochemical variables is a useful tool for monitoring ursodeoxycholic acid (UDCA)-treated patients with primary biliary cholangitis (PBC). Several UDCA response criteria and scoring systems have been proposed for risk prediction in PBC, but these have not been validated in large external cohorts. METHODS: We performed a study on data of 1746 UDCA-treated patients with PBC from 25 centers in Europe, United States, and Canada. The prognostic performance of the risk scoring systems (GLOBE and UK-PBC) and the UDCA response criteria (Barcelona, Paris I, Paris II, Rotterdam, and Toronto) were evaluated. We regarded cirrhosis-related complications (ascites, variceal bleeding, and/or hepatic encephalopathy) as clinical end points. RESULTS: A total of 171 patients reached a clinical end point during a median 7 years (range 1-16 years) of follow-up. The 5-, 10- and 15-year adverse outcome-free survivals were 95%, 85%, and 77%. The GLOBE and UK-PBC scores predicted cirrhosis-related complications better than the UDCA response criteria. The hazard ratio (HR) for a 1 standard deviation increase was HR 5.05 (95% confidence interval (CI): 4.43-5.74, P < 0.001) for the GLOBE score and HR 3.39 (95% CI: 3.10-3.72, P < 0.001) for the UK-PBC score. Overall, the GLOBE and UK-PBC risk scores showed similar and excellent prognostic performance (C-statistic, 0.93; 95% CI: 0.91%-95% vs 0.94; 95% CI: 0.91%-0.96%). DISCUSSION: In our international, multicenter PBC cohort, the GLOBE and UK-PBC risk scoring systems were good predictors of future cirrhosis-related complications.

We studied the efficacy and safety of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy in pediatric patients with autoimmune hepatitis (AIH) who were intolerant or non-responders to standard therapy (corticosteroid and azathioprine). We performed a retrospective study of data from 13 centers in Europe, USA, and Canada. Thirty-eight patients (< 18 years old) who received second-line therapy (18 MMF and 20 tacrolimus), for a median of 72 months (range 8-182) were evaluated. Patients were categorized into two groups: Group 1 (n = 17) were intolerant to corticosteroid or azathioprine, and group 2 (n = 21) were non-responders to standard therapy. Overall complete response rates were similar in patients treated with MMF and tacrolimus (55.6 vs. 65%, p = 0.552). In group 1, MMF and tacrolimus maintained a biochemical remission in 88.9 and 87.5% of patients, respectively (p = 0.929). More patients in group 2 given tacrolimus compared to MMF had a complete response, but the difference was not statistically significant (50.0 vs. 22.2%, p = 0.195). Biochemical remission was achieved in 71.1% (27/38) of patients by tacrolimus and/or MMF. Decompensated cirrhosis was more commonly seen in MMF and/or tacrolimus non-responders than in responders (45.5 vs. 7.4%, p = 0.006). Five patients who received second-line therapy (2 MMF and 3 tacrolimus) developed side effects that led to therapy withdrawal. Long-term therapy with MMF or tacrolimus was generally well tolerated by pediatric patients with AIH. Both MMF and tacrolimus had excellent efficacy in patients intolerant to corticosteroid or azathioprine. Tacrolimus might be more effective than MMF in patients failing previous therapy.

BACKGROUND AND AIM: Patients with liver cirrhosis and ascites have a poor prognosis with increased risk of infection related death, as advanced stages of cirrhosis are associated with immunodeficiency. We aimed to investigate immunologically active molecules in ascitic fluid and blood and their potential association to survival.MATERIALS AND METHODS: In an exploratory pilot study; blood and ascitic fluid from 34 patients with liver cirrhosis of different etiology were analyzed for pattern recognition molecules (ficolin-1, ficolin-2, ficolin-3 and MBL) and complement proteins (C4 and C3). An observational follow-up study (minimum 17 months) was conducted to assess the association to all-cause mortality or liver transplantation.RESULTS: Ficolin-1, ficolin-2, MBL, C4 and C3 in ascitic fluid and ficolin-1, C4 and C3 in blood were significantly (p = .001-.027) lower in patients with Child-Pugh stage C (n = 16, 47%) compared to Child-Pugh stage B cirrhosis (n = 18, 53%). In multivariate COX-regression analysis low levels of ficolin-1(p = .036) and C3 (p = .025) in ascitic fluid and C4(p = .005) and C3 (p = .032) in serum were associated with all-cause mortality or liver transplantation independent of Child-Pugh score.CONCLUSION: Levels of lectin-complement pathway molecules in ascitic fluid and blood are lower in patients with more advanced stage of cirrhosis. Low C4 and C3 in serum and C3 and ficolin-1 in ascitic fluid are risk factors for all-cause mortality or liver transplantation independently of liver function in patients with cirrhosis and ascites.

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) may be complicated by primary sclerosing cholangitis (PSC). We aimed to assess the characteristics of Danish PSC-IBD patients and to compare their prognosis with IBD patients without PSC.METHODS: A retrospective nationwide population-based cohort of 257 PSC-IBD patients was assessed through Danish national registries and manual scrutiny of patient files.RESULTS: For all PSC-IBD patients diagnosed after 1976 (n = 222) and 8231 IBD controls (ie, without PSC), the cumulative probability of resective surgery, liver transplantation, cancer, and survival from 1977 through 2011 was estimated and compared by log-rank test and Cox regression. PSC-IBD patients primarily had ulcerative colitis (UC) (72%), were diagnosed in young adulthood (median age at IBD diagnosis, 23 years), and 9% were smokers. Among PSC-UC patients 78% had pancolitis at diagnosis. Among patients with PSC and Crohn's disease (CD) 91% had colonic involvement. The PSC-IBD patients had a significantly higher probability of receiving resective surgery (HR; 2.13, 95% CI: 1.50-3.03); of developing colorectal cancer (CRC) (HR; 21.4, 95% CI: 9.6-47.6), of cholangiocarcinoma (HR; 190, 95% CI: 54.8-660), and of dying (HR; 4.39, 95% CI: 3.22-6.00) as compared to non-PSC-IBD controls. The 25-year cumulative risk of liver transplantation was high (53%).CONCLUSIONS: This unselected population-based study shows that PSC-IBD patients not only have an extensive phenotype of IBD, they are also treated more intensively than other patients with IBD. However, the prognosis remains poor and without any apparent improvement over calendar time.

BACKGROUND & AIMS: 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. METHODS: We performed a retrospective study of data (from 19 centers 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 mo). 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 as a result of 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 with MMF had a complete response (56.5% vs 34%, respectively; 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 generally was 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 nonresponder patients compared with MMF.

OBJECTIVE: The idiosyncratic subtype of drug-induced liver injury (DILI) is a rare reaction to medical treatment that in severe cases can lead to acute liver failure and death. The aim of this study was to describe the presentation and outcome of DILI and to identify potential predictive factors of poor outcome.MATERIALS AND METHODS: We identified all patients diagnosed with DILI at the Department of Hepatology, Rigshospitalet, from March 2007 to November 2012. The following parameters were registered from patient files: drug causing DILI, symptoms, comorbidity, biochemistry, treatment and outcome.RESULTS: Of 43 patients, 25 (58%) were female with a mean age of 54 years. The two most frequent causes of DILI were Disulfiram (30%) and antibiotics (19%). The most common symptoms were jaundice, nausea, fatigue and gastrointestinal discomfort. At the time of admission, the most frequent biochemical findings included bilirubin elevated to above 3.2 × ULN, ALT elevated to above 9 × ULN in 86%, INR above 1.4 in 70%. Twenty two patients needed treatment in the liver intensive care unit. Fifteen patients developed acute liver failure with a severe outcome. Six patients were liver transplanted and nine patients died. Jaundice, a moderately elevated bilirubin level or INR at presentation was predictive of severe outcome.CONCLUSION: In this retrospective study, 35% of patients with DILI developed severe acute liver failure and were either liver transplanted or died. Our results underline that DILI may be severe and run a fatal course, and that bilirubin and INR levels may predict poor outcome.

Udgivelsesdato: 2010-Apr, Surfactant protein D (SP-D) is an oligomeric calcium-dependent lectin with important roles in innate host defence against infectious microorganisms. Several studies have shown that patients with inflammatory lung disease have elevated levels of circulating SP-D, and serum SP-D has been suggested to be used as a biomarker for disease e.g. in COPD. We aimed to investigate the variation of circulating SP-D in healthy individuals in and between days for 6 months. In addition, we studied the SP-D response to a standardized physical exercise programme. SP-D was measured in serum using a 5-layered ELISA technique. We found that circulating SP-D remained constant over a 6-month period. However, during the course of one day SP-D varied significantly. Median SP-D peaked at 10 a.m. at 1009 ng/ml (95% CI: 803-1497), subsequently decreasing to nadir at 10 p.m. at 867 ng/ml (95% CI: 650-1148)(P<0.00005). Median pre-exercise level of SP-D was 746 ng/ml (95% CI: 384-2035), and immediately after cessation of physical activity the median SP-D level was 767 ng/ml (95% CI: 367-1885) (P=0.248). Our findings underscore the importance of standardized blood sampling conditions in future studies on the potential role of SP-D as a biomarker. Importantly, stable measures of systemic SP-D over a prolonged period support that SP-D is suitable for biomarker studies.

Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) are central components of the MBL pathway of complement activation, and may have potential as clinical biomarkers in colorectal cancer (CRC). Prior to clinical usage, knowledge of the biological variations of the molecules is needed. We here investigate variations of MBL and MASP-2 in healthy persons over time and in relation to gender, age and physical activity. MBL and MASP-2 concentrations were determined in serum from healthy adults over a 3-week period and this was repeated 6 months later (n = 32); during a 24-h period (n = 16); and in relation to physical exercise (n = 14). Concentrations in serum and plasma were compared (n = 198). No significant variation over 6 months and no circadian variation was found for MBL (P = 0.39 and P = 0.34 respectively) or MASP-2 (P = 0.54 and P = 0.55). Physical exercise did not affect the levels (P > 0.8). Serum and plasma levels were only marginally different, and were independent of age and gender. Circulating levels of MBL and MASP-2 are stable over time in healthy individuals, which is advantageous for their potential application as biomarkers. Udgivelsesdato: oktober, Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) are central components of the MBL pathway of complement activation, and may have potential as clinical biomarkers in colorectal cancer (CRC). Prior to clinical usage, knowledge of the biological variations of the molecules is needed. We here investigate variations of MBL and MASP-2 in healthy persons over time and in relation to gender, age and physical activity. MBL and MASP-2 concentrations were determined in serum from healthy adults over a 3-week period and this was repeated 6 months later (n = 32); during a 24-h period (n = 16); and in relation to physical exercise (n = 14). Concentrations in serum and plasma were compared (n = 198).

The mannan-binding lectin (MBL) pathway of complement activation is important in host defence against pathogens and possibly against cancer. We investigated the effect of major surgery on two central components of the MBL pathway; MBL and the MBL-associated serine protease MASP-2, and for comparison also measured the interleukin (IL)-6 and C-reactive protein (CRP) levels. Serial blood samples were obtained from patients belonging to two different cohorts. Cohort 1 comprised 60 patients undergoing open or laparoscopic colectomy for benign disease (n = 12) or colon cancer (n = 48). Cohort 2 comprised 27 patients undergoing elective, open surgery for colorectal cancer, and was included in order to cover blood sampling between days 2 and 6. As expected, the surgical stress induced a marked acute phase response, as evidenced by a large increase in IL-6 (18-fold) and CRP (13-fold) levels with maximum at 12 h and 2 days, respectively. However, in both cohorts the levels of MBL and MBL-associated serine protease 2 (MASP-2) were largely unaffected, except for a minor but significant increase around day 8 in cohort 1. The preoperative levels of IL-6 and CRP were correlated significantly in both cohorts (r = 0.71, P < 0.0001 and r = 0.65, P = 0.005, respectively). Preoperative MASP-2 correlated with preoperative CRP (r = 0.59, P = 0.001) and IL-6 (r = 0.55, P = 0.02) in cohort 2 only. In contrast to the marked effects on the levels of IL-6 and CRP, the surgery influenced only marginally the two proteins of the MBL pathway.

OBJECTIVE: Sixty to 70% of upper gastrointestinal bleeding episodes in patients with cirrhosis are caused by oesophageal varices. Prophylaxis is indicated in patients with varices and a hepatic venous pressure gradient (HVPG) above 12 mmHg. The study of the natural history of patients with lower HVPG has been sparse. In this study, long-term survival and the risk of complications in mild portal hypertension were analysed. MATERIAL AND METHODS: Sixty-one patients with cirrhosis and HVPG below 10 mmHg were included in the study. Data were collected from medical files and National Patient Registries. Variceal bleeding, hepatic encephalopathy and death related to cirrhosis were registered. Thirty-nine patients were graded as Child class A, 19 as class B and 3 as class C. Median survival time was 11 years. RESULTS: Twenty-eight patients (46%) developed one or more complications: variceal bleeding in 10 (16%) and hepatic encephalopathy in 18 patients (30%). Twenty-three patients (38%) died from complications of cirrhosis. Two patients (3%) died from variceal bleeding, another two (3%) from gastrointestinal bleeding of unidentified source. Survival rate was significantly decreased compared with that in the background population. CONCLUSIONS: The frequency of complications in patients with mild portal hypertension is considerable, and guidelines for follow-up or medical prophylaxis are warranted. The risk of bleeding from oesophageal varices is low and bleeding-related deaths rare.
