IntroductionThe combination of everolimus (EVR) and low-dose tacrolimus (lowTAC) prevents T cell-mediated rejection of liver grafts as sufficiently as high-dose tacrolimus (highTAC) and mycophenolate, but is associated with a preserved kidney function within the first years after orthotopic liver transplantation (OLT). However, none of the available studies assessed the histological pattern of graft injury or fibrosis in surveillance biopsies (svLbx).MethodsAll svLbx taken under at least one month of stable immunosuppression with either EVR (aim 3-8 ng/ml) combined with lowTAC (aim 3-5 ng/ml) or highTAC (aim 5-8 ng/ml) combined with mycophenolate (500-1500 mg/day) within the first three to four years after OLT at our center were included. Patients who were switched to EVR because of insufficient control of alloreactivity were excluded.ResultsReasons for switches to EVR were mainly malignancies before or after OLT, or chronic kidney injury. We were able to include 20 svLbx with EVR/lowTAC and 49 with highTAC/mycophenolate. Both groups had similar liver enzymes and similar kidney function. The EVR/lowTAC group exhibited lower TAC trough levels at svLbx (4.4 vs. 6.6 ng/ml; pDiscussionIn conclusion, EVR/lowTAC seems to control alloreactivity and histological graft injury as sufficiently as highTAC/mycophenolate within the first 3-4 years after OLT.

Autoimmune hepatitis (AIH) is a chronic immune-mediated inflammatory liver disease. It is known that AIH originates not from the spleen but from the liver itself. Nonetheless, most details of the etiology and pathophysiology are unknown. We induced experimental murine AIH (emAIH) in NOD/Ltj mice by single administration of a replication-deficient adenovirus and performed splenectomy during late-stage disease. Biochemical disease remission occurred, which was characterized by improvement in transaminase levels. The causes of this remission included a shift in the transcriptomic signature of serum proteins toward regeneration. At the cellular level, there was a marked decrease in activated CD8+T cells and an increase in intrahepatic regulatory T cells (Tregs). Here, intrahepatic Treg numbers correlated with biochemical remission. Notably, an imbalance in the T-cell/B-cell ratio was observed, with a disproportionate increase in total B cells. In summary, intrahepatic increases in Tregs, biochemical remission, and regeneration could be induced by splenectomy in the late stage of emAIH.

Background Recently, a randomized controlled trial (RCT) demonstrated rapid but individually variable hemodynamic improvement with therapeutic plasma exchange (TPE) in patients with septic shock. Prediction of clinical efficacy in specific sepsis treatments is fundamental for individualized sepsis therapy. Methods In the original RCT, patients with septic shock of Results A continuous effect of TPE on the reduction in NE doses over the initial 24 h was observed (SOC group: estimated NE dose reduction of 0.005 µg/kg/min per hour; TPE group: 0.018 µg/kg/min per hour, p = 0.004). Similarly, under TPE, serum lactate levels, continuously decreased over the initial 24 h in the TPE group, whereas lactate levels increased under SOC (p = 0.001). A reduction in biomarkers and disease mediators (such as PCT (p = 0.037), vWF:Ag (p p = 0.009), sTie-2 (p = 0.005)) along with a repletion of exhausted protective factors (such as AT-III (p = 0.026), Protein C (p = 0.012), ADAMTS-13 (p = 0.008)) could be observed in the TPE but not in the SOC group. In a multivariate mixed effects model, increasing baseline lactate levels led to greater NE dose reduction effects with TPE as opposed to SOC (p = 0.004). Conclusions Adjunctive TPE is associated with the removal of injurious mediators and repletion of consumed protective factors altogether leading to preserved hemodynamic stabilization in refractory septic shock. We identified that baseline lactate concentration as a potential response predictor might guide future designing of large RCTs that will further evaluate TPE with regard to hard endpoints.

Background & Aims: Evidence for the benefit of scheduled imaging for early detection of hepatobiliary malignancies in primary sclerosing cholangitis (PSC) is limited. We aimed to compare different follow-up strategies in PSC with the hypothesis that regular imaging improves survival. Methods: We collected retrospective data from 2975 PSC patients from 27 centres. Patients were followed from the start of scheduled imaging or in case of clinical follow-up from 1 January 2000, until death or last clinical follow-up alive. The primary endpoint was all-cause mortality. Results: A broad variety of different follow-up strategies were reported. All except one centre used regular imaging, ultrasound (US) and/or magnetic resonance imaging (MRI). Two centres used scheduled endoscopic retrograde cholangiopancreatography (ERCP) in addition to imaging for surveillance purposes. The overall HR (CI95%) for death, adjusted for sex, age and start year of follow-up, was 0.61 (0.47-0.80) for scheduled imaging with and without ERCP; 0.64 (0.48-0.86) for US/MRI and 0.53 (0.37-0.75) for follow-up strategies including scheduled ERCP. The lower risk of death remained for scheduled imaging with and without ERCP after adjustment for cholangiocarcinoma (CCA) or high-grade dysplasia as a time-dependent covariate, HR 0.57 (0.44-0.75). Hepatobiliary malignancy was diagnosed in 175 (5.9%) of the patients at 7.9 years of follow-up. Asymptomatic patients (25%) with CCA had better survival if scheduled imaging had been performed. Conclusions: Follow-up strategies vary considerably across centres. Scheduled imaging was associated with improved survival. Multiple factors may contribute to this result including early tumour detection and increased endoscopic treatment of asymptomatic benign biliary strictures.

Background Non-occlusive mesenteric ischemia (NOMI) is a life-threatening condition occurring in patients with shock and is characterized by vasoconstriction of the mesenteric arteries leading to intestinal ischemia and multi-organ failure. Although minimal invasive local intra-arterial infusion of vasodilators into the mesenteric circulation has been suggested as a therapeutic option in NOMI, current knowledge is based on retrospective case series and it remains unclear which patients might benefit. Here, we prospectively analyzed predictors of response to intra-arterial therapy in patients with NOMI. Methods This is a prospective single-center observational study to analyze improvement of ischemia (indicated by reduction of blood lactate > 2 mmol/l from baseline after 24 h, primary endpoint) and 28-day mortality (key secondary endpoint) in patients with NOMI undergoing intra-arterial vasodilatory therapy. Predictors of response to therapy concerning primary and key secondary endpoint were identified using a) clinical parameters as well as b) data from 2D-perfusion angiography and c) experimental biomarkers of intestinal injury. Results A total of 42 patients were included into this study. At inclusion patients had severe shock, indicated by high doses of norepinephrine (NE) (median (interquartile range (IQR)) 0.37 (0.21–0.60) μg/kg/min), elevated lactate concentrations (9.2 (5.2–13) mmol/l) and multi-organ failure. Patients showed a continuous reduction of lactate following intra-arterial prostaglandin infusion (baseline: (9.2 (5.2–13) mmol/l vs. 24 h: 4.4 (2.5–9.1) mmol/l, p 2 mmol/l at 24 h following intervention. Initial higher lactate concentrations and lower NE doses at baseline were independent predictors of an improvement of ischemia. 28-day mortality was 59% in patients with a reduction of lactate > 2 mmol/l 24 h after inclusion, while it was 85% in all other patients (hazard ratio 0.409; 95% CI, 0.14–0.631, p = 0.005). Conclusions A reduction of lactate concentrations was observed following implementation of intra-arterial therapy, and lactate reduction was associated with better survival. Our findings concerning outcome predictors in NOMI patients undergoing intra-arterial prostaglandin therapy might help designing a randomized controlled trial to further investigate this therapeutic approach.

Background: Patients with advanced hepatocellular carcinoma (HCC) arising in nonalcoholic fatty liver disease (NAFLD) may not be suitable for systemic therapy due to metabolic syndrome-related diseases. Recent trials did not show a survival benefit of radioembolization (RE) compared to sorafenib in advanced stage HCC but RE may represent an adequate alternative in patients with contraindications to systemic therapy due to its favorable safety profile. Aim: To investigate the impact of NAFLD-related comorbidities on safety and efficacy of RE for HCC treatment in a retrospective monocentric cohort study. Patients and Methods: Safety and efficacy of RE were evaluated in patients with NAFLD-associated HCC. Hepatitis B virus (HBV)-related HCC patients served as controls, exhibiting matching Barcelona Liver Cancer Clinic (BCLC) stages while showing significantly fewer metabolic comorbidities. Results: Overall, 87 HCC patients with NAFLD (mean age 71.3 ± 6.9 years) and 62 HCC patients with HBV (mean age 58.8 ± 10.9 years) not amenable to surgical or conventional locoregional treatments were included. Patients with HBV-related HCC had a comparable liver function to HCC patients with NAFLD. RE treatment-related toxicity did not differ between the two groups (increase in bilirubin Common Terminology Criteria for Adverse Events grade in 29 [38.7%] NAFLD and 20 [39.2%] HBV patients, p = 0.91). Overall survival was similar in HCC patients with NAFLD and HBV (11.1 [interquartile range, IQR, 18.27] vs. 9.3 months [IQR 14.73], p = 0.38), also in the subgroup analyses of BCLC B and C stages. Conclusion: RE showed similar survival outcomes at a comparable toxicity profile in HCC patients with NAFLD and HBV. NAFLD-associated metabolic comorbidities did not exhibit limitations for RE while offering comparable therapeutic efficacy as compared to HBV patients.

With the aging of the hepatitis C virus (HCV)-infected patient cohort and the availability of highly effective and tolerable treatment regimens, an increasing number of elderly patients are now eligible for HCV therapy. This study investigated clinical and epidemiologic characteristics of elderly HCV-infected patients as well as the effectiveness and safety of available therapies. Patients were enrolled into the German Hepatitis C Registry (DHC-R), a prospective, multicenter, real-world cohort study. Patients were treated at the discretion of the physician, and data were collected by a web-based system. Of 7133 patients who initiated treatment, 686 (9.6%) were > 70 years of age. In patients > 70 years, intent-to-treat (ITT) SVR12 was 92.6% (514/555) compared to 90.7% (4521/4985) in patients ≤ 70 years of age. Overall, adverse events (AEs) were reported in 374 (54.5%) and 3435 patients (53.3%) > 70 or ≤ 70 years of age; 7.6% (52) and 3.6% (235) in the respective age groups had a serious AE. Twenty-two (3.2%) and 62 (1.0%) of the patients > 70 or ≤ 70 years discontinued treatment due to AEs. Death was reported in 34 patients, of whom eight were > 70 years of age. Frequent comorbidities in patients > 70 years of age were cardiac disease, renal disease and diabetes. Psychiatric disorders, substance abuse and viral co-infection were more frequent in younger patients. Direct-acting antiviral therapies were well tolerated in patients older than 70 years. SVR12 rates in the elderly patient group were similar to those observed in younger patients. Differences in the prevalence of comorbidities between age groups warrant individualized attention with respect to drug–drug interactions and therapy adherence. The study was registered in the German Clinical Trials Register, DRKS-ID: DRKS00009717.

Background: Accurate assessment of hepatic fibrosis in patients with chronic HBeAg-negative Hepatitis B is of crucial importance not only to predict the long-term clinical course, but also to evaluate antiviral therapy indication. The aim of this study was to prospectively assess the utility of point shear wave elastography (pSWE) for longitudinal non-invasive fibrosis assessment in a large cohort of untreated patients with chronic HBeAg-negative hepatitis B virus (HBV) infection. Methods: 407 consecutive patients with HBeAg-negative HBV infection who underwent pSWE, transient elastography (TE) as well as laboratory fibrosis markers, including fibrosis index based on four factors (FIB-4), aspartate to platelet ratio index (APRI) and FibroTest, on the same day were prospectively followed up for six years. Patients were classified into one of the three groups: inactive carriers (IC, HBV-DNA &lt, 2000 IU/mL and ALT &lt, 40 U/L), grey zone group 1 (GZ-1, HBV DNA &lt, 2000 IU/mL and ALT &gt, grey zone group 2 (GZ-2, HBV-DNA &gt, 40 U/L). Results: pSWE results were significantly correlated with TE (r = 0.29, p &lt, 0.001) and APRI (r = 0.17, p = 0.005). Median pSWE values did not differ between IC, GZ-1 and GZ-2 patients (p = 0.82, p = 0.17, p = 0.34). During six years of follow-up, median pSWE and TE values did not differ significantly over time (TE: p = 0.27, pSWE: p = 0.05). Conclusion: Our data indicate that pSWE could be useful for non-invasive fibrosis assessment and follow-up in patients with HBeAg-negative chronic HBV infection.

SMYD3 (SET and MYND domain-containing protein 3) is involved in histone modification, which initiates oncogenesis by activating transcription of multiple downstream genes. To investigate associations of variable numbers of tandem repeats (VNTR) variants in the SMYD3 gene promoter, SMYD3 serum levels and SMYD3 mRNA expression in hepatitis B virus (HBV) infection and clinical progression of related liver disease. SMYD3 VNTRs were genotyped in 756 HBV patients and 297 healthy controls. SMYD3 serum levels were measured in 293 patients and SMYD3 mRNA expression was quantified in 48 pairs of hepatocellular tumor and adjacent non-tumor liver tissues. Genotype SYMD3 VNTR 3/3 was more frequent among HCC patients than in controls (Padjusted = 0.037). SMYD3 serum levels increased according to clinical progression of liver diseases (P = 0.01); HCC patients had higher levels than non-HCC patients (P = 0.04). Among patients with SMYD3 VNTR 3/3, HCC patients had higher SMYD3 levels than others (P

Contains fulltext : 215528.pdf (Publisher’s version ) (Open Access) Chronic hepatitis B virus (HBV) infection may follow four different consecutive phases, which are defined by virology as well as biochemical markers and differ in terms of prognosis and need for antiviral treatment. Currently, host responses reflected by immune markers are not considered in this definition. We aimed to study soluble immune markers and their distribution in different phases of chronic HBV infection. In this cross-sectional retrospective study, we investigated a panel of 14 soluble immune markers (SIM) including CXCL10 in 333 patients with chronic HBV infection. In a small cohort of HBeAg positive patients we analyzed SIM before and after HBeAg seroconversion and compared seroconverters to patients with unknown outcome. Significant differences were documented in the levels of several SIM between the four phases of chronic HBV infection. The most pronounced difference among all investigated SIM was observed for CXCL10 concentrations with highest levels in patients with hepatitis. TGF-beta and IL-17 revealed different levels between HBeAg negative patients. HBeAg positive patients with HBeAg seroconversion presented higher amounts of IL-12 before seroconversion compared to HBeAg positive patients with unknown follow up. SIM such as CXCL10 but also IL-12, TGF-beta and IL-17 may be useful markers to further characterize the phase of chronic HBV infection.

Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG-interferon alpha-2a (PEG-IFN alpha-2a) is the only effective treatment but its long-term clinical impact is unclear. the aim of this study was to investigate the long-term outcome after 48 weeks of pegylated interferon alpha-2a therapy. We performed a retrospective follow-up study of the Hep-Net-International-Delta-Hepatitis-Intervention-Study 1 (HIDIT-I trial). Patients had received 48 weeks of treatment with either PEG-IFN alpha-2a plus adefovir dipivoxil (ADV) (Group I), PEG-IFN alpha-2a alone (Group II) or adefovir dipivoxil alone (Group III). Liver-related complications were defined as liver-related death, liver transplantation, liver cancer and hepatic decompensation defined as development of Child-Pugh scores B or C or an increase in Model for End-stage Liver Disease (MELD) scores of five or more points in relation to baseline values. Patients were considered for further analysis when they were retreated with PEG-IFN alpha-2a. Follow-up data (at least 1 visit beyond post-treatment week 24) were available for 60 patients [Group I, (n = 19), Group II (n = 20), Group III (n = 21)]. Mean time of follow-up was 8.9 (1.6 - 13.4) years. 19 patients were retreated with IFN-based therapy: 42% (n = 8) in PEG-IFN alpha-2a arms and 58% (n = 11) in the adefovir only arm. Clinical complications on long-term follow-up occurred in 17 patients and were associated with nonresponse to therapy and baseline cirrhosis. the annual event-free survival rate in patients with cirrhosis vs noncirrhotic patients at year 5 and 10 was 70% vs 91% and 35% vs 76%. Long-term follow-up of a large randomized clinical trial suggests that off-treatment HDV RNA response to PEG-IFN alpha-2a treatment leads to improved clinical long-term outcome., German Centre for Infection Research (DZIF), partner site Hannover-Braunschweig; German Liver Foundation; EASL registry grant, This study was funded by the German Centre for Infection Research (DZIF), partner site Hannover-Braunschweig with a grand to the HepNet Study-House, the German Liver Foundation and an EASL registry grant.

The role of low levels of HDV-RNA during and after interferon therapy of hepatitis D is unknown. We re-analysed HDV RNA in 372 samples collected in the HIDIT-2 trial (Wedemeyer et al, Lancet Infectious Diseases 2019) with the Robogene assay (RA; Jena Analytics). Data were compared with the previously reported in-house assay (IA). We detected HDV-RNA in one-third of samples previously classified as undetectable using the highly sensitive RA. Low HDV viraemia detectable at week 48 or week 96 was associated with a high risk for post-treatment relapse, defined as HDV RNA positivity in both assays at week 120. HDV RNA relapses occurred in 10/15 (67%) patients with detectable low HDV RNA at week 48 and in 10/13 (77%) patients with low viraemia samples at week 96. in contrast, the post-treatment relapse rate was lower in patients with undetectable HDV RNA in both assays during treatment., Projekt DEAL, Open access funding enabled and organized by Projekt DEAL.

The impact of direct-acting antiviral (DAA) therapies on fibrosis regression remains uncertain. In the current study, we prospectively evaluated dynamics of liver stiffness by transient elastography (TE) in patients with chronic HCV infection receiving DAA-based treatment. Patients (260) were enrolled in the German Hepatitis C-Registry (DHC-R), a national multicentre real-world cohort. Liver stiffness (LS) was assessed at baseline, end of treatment (EOT) and 24 weeks after EOT (FU24) by TE. Biochemical, virological and clinical data were obtained in parallel. In patients with SVR, there was a significant improvement of LS between baseline (median [range], 8.6 [1.7-73.5] kPa) and FU24 (7.9 [1.7-75 kPa]; P < .0001) as well as between EOT (8.4 [1.7-73.5 kPa]) and FU24 [P < .0001]. Stratified by fibrosis stage, patients classified into F4 had higher magnitude of LS reduction between BL (median [range], 25.1 [13.5-73.5] kPa) and FU24 (21.5 [3.1-75] kPa; P = .002) compared to those with F2-F3 (8.9 [7.1-12.4] kPa and 8.8 [4.2-29.1]; P = .060) or F0-F1 (5.3 [1.7-7] kPa and 5.2 [1.7-7.7]; P = .064). In cirrhotic patients, low platelets were significantly associated with lack of liver stiffness improvement, both at EOT (P = .018) and at FU24 (P = .012). LS significantly correlated with ALT (r = .371), AST (r = .552), platelets (r = -.499), GGT (r = .250), bilirubin (r = .230), APRI score (r = .512), FIB-4 score (r = .517) and FORNS index (r = .562); P < .0001. Liver elastography improved significantly in our real-world cohort after DAA-based therapy. As LS correlates similarly with transaminase levels and serum fibrosis markers, it might reflect both reduction of necroinflammation and fibrosis regression.
