Methotrexate is widely used to treat some inflammatory chronic disorders, though it is hampered by the risk of liver fibrosis. Many recommendations have been made to assess methotrexate-related hepatotoxicity, including liver biopsy. However, other noninvasive methods to assess liver fibrosis have been developed and could be implemented for patients treated with methotrexate. The aim of the study was to compare the prevalence of liver fibrosis by means of noninvasive methods [aspartate transaminase-to-platelet ratio index (APRI) Forns index, and transient elastography] in patients with Crohn's disease exposed or not to methotrexate, and to identify risk factors for liver fibrosis. Prospective, cross-sectional study. All patients with Crohn's disease exposed to methotrexate were included and compared to an unselected cohort of outpatients with Crohn's disease never exposed to methotrexate. A total of 84 patients with Crohn's disease, 56 exposed to methotrexate, and 28 controls, were included. Significant liver fibrosis was found in 7% of methotrexate-exposed patients with Crohn's disease and 10% of controls as measured by transient elastography, and in 7% of controls as measured by the Forns index. No cases of liver fibrosis were detected by APRI. Only alcohol consumption, diabetes mellitus, and age were associated with significant liver fibrosis. Significant liver fibrosis is uncommon among patients with Crohn's disease, even among those exposed to methotrexate. The risk of liver fibrosis in Crohn's disease seems to depend on common risk factors for liver disease.

The risk of liver fibrosis in Crohn's disease seems to depend on common risk factors for liver disease. Two-dimensional shear wave elastography (2D-SWE) is a new ultrasound-based elastography method to evaluate liver fibrosis in the daily practice. However, the utility of 2D-SWE among the other liver fibrosis markers is unclear. We enrolled 141 consecutive patients with hepatitis C virus infection, 66 men and 75 women (median age, 67 years), who underwent liver biopsy and 2D-SWE (LOGIQ E9, GE Healthcare, Wauwatosa, WI, USA). We compared the diagnostic accuracy of the 2D-SWE with those of magnetic resonance elastography (MRE; MR-Touch, GE Healthcare, Milwaukee, WI, USA), Mac-2 binding protein glycosylation isomer (M2BPGi), fibrosis-4 index (FIB-4) and platelet counts (PLT), using the histologic METAVIR scoring as the reference standard. The areas under the receiver operating characteristics curves (AUROCs) of 2D-SWE, MRE, M2BPGi, FIB-4 and PLT for ≥F2, ≥F3 and F4 were 0.86, 0.88, 0.79, 0.81 and 0.77; 0.92, 0.93, 0.86, 0.87 and 0.83; and 0.91, 0.97, 0.85, 0.85 and 0.82, respectively. https://www.selleckchem.com/products/bay-1816032.html For diagnosing ≥F2 and ≥F3, the AUROCs of 2D-SWE and those of MRE showed no significant differences, and both 2D-SWE and MRE showed significantly higher AUROCs than the other markers. For diagnosing F4, the AUROC of MRE was significantly higher than those of other fibrosis markers. 2D-SWE has an excellent diagnostic accuracy equivalent to that of MRE for assessing significant (≥F2) and severe (≥F3) fibrosis. MRE demonstrated a higher AUROC than 2D-SWE, but this last one has advantages such as lower cost, fewer contraindications and greater ease of performance than MRE. 2D-SWE has an excellent diagnostic accuracy equivalent to that of MRE for assessing significant (≥F2) and severe (≥F3) fibrosis.

Current guidelines for chronic hepatitis B (CHB) patients are to undergo surveillance for hepatocellular carcinoma (HCC) with 6-month ultrasonography. We aimed to compare detection rates of very-early-stage HCC in two groups group A, undergoing 6-month ultrasonography versus group B, undergoing 6-month ultrasonography alternating with dynamic computed tomography (CT). This retrospective study assessed 2151 CHB patients under entecavir/tenofovir therapy from 2007 to 2016. Detection rates of very-early-stage HCC were compared between groups A/B at intermediate/high risk based on platelets, age, gender-hepatitis B scores. The primary endpoint was the proportion of patients in each group with very-early-stage HCC. Cox proportional hazards model was used to assess the effect of surveillance modalities to detect very-early-stage HCC. Five-year cumulative HCC incidence rates in group A were 15.0% not significantly different from 18.2% in group B at high risk (P = 0.17). Detection rates of very-early-stage HCC were significantly higher in group B than in group A (P < 0.001), and surveillance using CT alternating with ultrasonography was significantly associated with detection of very-early-stage HCC (hazard ratio 3.89, P < 0.001). Among intermediate-risk patients, difference between detection rates of very-early-stage HCC in groups A and B was not significant (P = 0.30), and surveillance using CT alternating with ultrasonography was not significantly associated with detection of very-early-stage HCC (hazard ratio 1.61, P = 0.23). In high-risk CHB patients, surveillance using CT alternating with ultrasonography led to higher detection rates of very-early-stage HCC compared to surveillance using ultrasonography. In high-risk CHB patients, surveillance using CT alternating with ultrasonography led to higher detection rates of very-early-stage HCC compared to surveillance using ultrasonography.In this study we analyzed the feasibility and safety of single-step multiple transluminal gateway drainage (MTGD) for complex walled-off necrosis (WON) using lumen-apposing metal stents (LAMSs). Six patients underwent endoscopic ultrasound (EUS)-guided MTGD using two LAMSs. Technical success was 100%. The mean procedure time was 29 min. The mean number of direct endoscopic necrosectomy sessions per patient was 2. Two of six patients developed adverse events, which was bleeding in both cases and treated endoscopically and surgically, respectively. The mean hospital stay was 52.5 days. No patients had residual necrosis or WON recurrence. Although the limited number of patients, the single-step MTGD using electrocautery-LAMSs can be considered a feasible and well-tolerated treatment option for patients with complex WON. Nevertheless, larger randomized controlled studies are needed in order to confirm our data and better define the advantages of this technique.
