The 1.8% agarose gel and MultiDoc-It digital imaging System (UVP, Upland, CA) were used. The bEnd3 cells were grown Navitoclax concentration to confluence on 100-cm2 culture plates in Dulbecco’s modified Eagle’s medium with 4.5 g/L glucose, 3.7 g/L sodium bicarbonate, 4 mM glutamine, 10% fetal bovine serum, 100 U/mL penicillin, and 100 g/mL streptomycin. Cells were transfected with GFP-tagged MMP-9 and p38 MAPK cDNA using Lipofectamine 2000 (Invitrogen). Cells transfected

with expression vector served as controls. Transfection efficiency was monitored by fluorescence microscopy. Cells were washed with phosphate-buffered saline (PBS) and collected into 1 mL of lysate buffer (50 mM Tris-HCl pH 7.3, 150 mM NaCl, 3 mM MgCl, 1 mM DTT, 1 mM EDTA, 1 mM EGTA, 1.0% Triton X-100), and supplemented with protease and phosphatase inhibitors. The extraction supernatant CH5424802 concentration was collected and 30 μg of protein from each sample

was resolved on 4%-20% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) gels, transferred, and immunoblotted onto nitrocellulose membrane. Anti-claudin-5, anti-occludin, anti-ZO-1, anti-ZO-2, anti-phospho p38 MAPK, anti-p38 MAPK, anti-IκBα, and anti-GAPDH antibodies were used as primary antibodies. The cells were lysed with ice-cold immunoprecipitation buffer (50 mM HEPES, pH 7.5, 50 mM NaCl, 1% Triton X-100, 1 mM EDTA, 10 mM sodium pyrophosphate, 1 mM Na3VO4, 30 mM 2-(p-nitrophenyl) phosphate, 100 mM NaF, 10% glycerol, 1.5 mM MgCl2, and protease inhibitor cocktail). Lysates were centrifuged at 14,000g for 5 minutes and the supernatant was immunoprecipitated with anti-EGFR and Dynabeads M-280 magnetic protein bead separation system (Invitrogen) overnight at 4°C. ALF was induced with an intraperitoneal

(ip) injection with azoxymethane (AOM) (Sigma-Aldrich) as described in our previous report.13 Control mice received saline. At 12 hours after AOM injection, ALF mice received 2 mg/kg of GM6001 or vehicle by way of ip injection. Control mice received vehicle. A heating pad was used to maintain body temperature at 37°C. The use of animals was institutionally approved CHIR-99021 solubility dmso in accordance with the National Institutes of Health Guide for the Care and Use of Laboratory Animals. The progression of hepatic encephalopathy was determined clinically.13 At the comatose stages the study mice were killed and their brains were removed. Hemibrains were homogenized at 150 mg tissue/mL of lysate buffer and processed for analysis. We recently reported that MMP-9 disrupts TJ proteins in mouse brain EC in vitro and in brains of mice with ALF.5 We also observed a significant increase in p38 MAPK activation in ALF mice.30 Thus, we investigated whether p38 MAPK contributes to occludin alterations in bEnd3 cells exposed to MMP-9. Similar to the methods used in our previous report,5 we overexpressed MMP-9 in bEnd3 cells.

Therapy against HCV infection was prescribed according to the caring physician criteria, based on consensus recommendations in effect along the study period, usually guided by HCV genotype and liver fibrosis stage. End-of-treatment response (ETR) was defined as undetectable serum HCV RNA at the planned date of treatment cessation. Sustained virological see more response (SVR) was defined as undetectable serum HCV RNA 24 weeks after the end of treatment. Liver steatosis and liver fibrosis were scored blindly by a central pathologist (M.A.J.). HS classification was based on the proportion of hepatocytes containing fat droplets using Brunt’s criteria18 and was classified as

follows: 0, absent steatosis; 1, less than 33% (i.e., mild HS); 2, 33%-66% (i.e., moderate HS); and 3, more than 66% (i.e., severe HS). Lobular inflammation was scored as follows: 0 = no foci; 1 = <2 foci (excludes 2 foci ×200 field); Natural Product Library mouse 2 = 2-4 (includes 2 and 4 foci ×200 field) 3 = >4 foci (excludes 4

foci ×200 field). Cytologic ballooning was classified as follows: 0, none; 1, few balloon cells; and 2, many cells/prominent ballooning. The NAFLD activity score (NAS) was calculated as the unweighted sum of steatosis, lobular inflammation, and hepatocellular ballooning scores.19 Scheuer’s score20 was applied to stage fibrosis as follows: 0, absent fibrosis; 1, portal fibrotic expansion; 2, extension of fibrosis to the lobule, but with few septa; 3, bridging fibrosis with numerous septa, with architectural distortion without cirrhosis; and 4, cirrhosis. The length of biopsies was recorded to assess their adequacy. The median (interquartile range; IQR) length of the initial biopsy was 17 (15-25) mm, whereas the respective figure of the second biopsy was 18 (16-25) mm. The primary outcome variable of the study was the progression in one or more grades in Brunt’s score. The associations of the following baseline factors with HS progression were analyzed: gender, age, body mass index (BMI), self-reported

Carbachol daily alcohol intake, diagnosis of diabetes mellitus (DM) following the American Diabetes Association criteria, fasting plasma glucose (FPG), cholesterol and triglycerides (TGs), HCV genotype, and Centers for Disease Control and Prevention (CDC) stage C. In addition, the following variables between biopsies and their relationship with HS progression were assessed: BMI, self-reported daily alcohol intake, FPG, cholesterol and TGs, response to treatment against HCV, CD4 cell counts at liver biopsies, plasma HIV RNA viral load at liver biopsies, exposure to ART, and changes in fibrosis stage. Cumulative exposure to individual antiretroviral drugs was calculated as the period in years receiving each antiretroviral drug between biopsies. Blood tests were drawn within 1 month before the liver biopsies. The secondary outcome variable was persistence of steatohepatitis between biopsies or progression to steatohepatitis in the final biopsy.

833, respectively (all P < 0.001). Significantly higher AUROC was observed for CLIF-SOFA vs. Child-Pugh score (P = 0.034) and there was a tendency towards higher AUROC for CLIF-SOFA as compared to MELD-Na score (P = 0.068). The best overall performance for CLIF-SOFA score was observed at a cutoff of 7. The mortality rate at 28-day, 90-day, and 1-year were 2.1%, 4.3% and 15.8% with CLIF-SOFA < 7, and 21.2%, 31.3%, MLN0128 and 53.5% with CLIF-SOFA ≥ 7, respectively

(log rank P < 0.001). Conclusions: CLIF-SOFA score is better than Child-Pugh score for predicting short term mortality in cirrhotic patients with acute decompensation. Although CLIF-SOFA score tend to be better, further studies are needed to verify that CLIF-SOFA score is more useful than MELD or MELD-Na scores in evaluating cirrhotic patients with acute decompensation.

Several organs can be involved with liver disturbance occurring in the majority of cases.

The outcome of DRESS is not well known in Acute Liver Failure (ALF). The aim of this study is to determinate the outcome of patients buy Talazoparib with ALF and predictive factors of a spontaneous improvement. Patients: From 1996 to 2013, 15 patients with ALF related to DRESS syndrome (10F, 5M, mean age: 39+17.2 years) were reviewed. The drugs implicated were: allopurinol (2), raltegravir (2), carbamazepine (2), levetiracetam (1), nevirapine (1), fluindrone (1), isoniazide or pyrazinamide (2) sulfasalazine (1) and unknown (2). At

admission, all patients were febrile and all presented cutaneous signs. Median prothrombin time (PT), total bilirubin, ALT and creatinin values were 34.5% (5-66), 69 μmol/l (8-353), 1569 IU/L (360-5176) and 107 μmol/L respectively. 5 patients presented more 2 visceral involvement. Liver histology (7 patients) identified lesions following: portal and sinusoidal infiltration by activated T cells mainly with cytotoxic phenotype mixed with a variable number of eosinophils; Rho severe periportal activity; spotty or confluent hepatocellular necrosis; Kupffer hyperplasia with frequent erythrophagocytosis. After admission, 8 patients received corticosteroid therapy and all were treated by N-Acetyl-Cysteine. The median duration of corticosteroid therapy was 14 days (2-101d). 7 patients were mechanically ventilated, 2 were placed on hemofiltration and 1 on albumin dialysis. A HSV6 and CMV reactivation were found in 3 and 1 patient respectively. Results: Of these 15 patients, 8 (53%) improved spontaneously and 7 (47%) worsened. Among these last, 5 underwent liver transplantation (LT) and 2 died. 3 of 7 (43%) of them, received corticosteroid therapy. The delay between admission and LT and death were 3 days and 5.5 days respectively.

4E). The results from RT-PCR analysis also indicate that the PGE2-mediated reduction in IFN-γ and IL-4 correlated with the inhibition of expression of T-bet and GATA-3 (Fig. 4F), key transcription factors regulating IFN-γ and IL-4 expression and maturation of NKT cells.16,17 Furthermore, knockdown of LEF1 in the NKT hybridoma led to partial reversing of PGE2-mediated inhibition of IL-2 production (Supporting Fig. 4), suggesting that LEF1 is a critical transcriptional factor that regulates PGE2 mediated anergy of NKT cells. Collectively, PGE2

stimulation led to activation PF-562271 of Wnt/β-catenin and subsequently the induction of NKT cell anergy. Exosome-like nanoparticles have a high capacity for binding PGE218 and maintaining its stability and thus activity. ELISA analysis of circulating exosome-like nanoparticles indicates that the circulating nanoparticles carry PGE2 (Supporting Fig. 5). FACS analysis of these circulating nanoparticles further indicates that they are also A33+ (Fig. 5A). A33+ is an intestinal epithelial marker, suggesting that these PGE2+ nanoparticles are derived from the intestine.

Nanosized particles in the gut migrate into the liver,19,20 where the majority of the NKT cells reside. We tested whether IDENs can induce liver NKT cell anergy. The results from electron microscopy examination showed that they are nanoparticles http://www.selleckchem.com/products/MG132.html in size (Fig. 5B). The nanoparticles were

enriched for PGE2 (Supporting Fig. 5). We then tested whether IDEN-associated PGE2 plays a role in the induction of NKT cell anergy. NKT cells were purified from the livers of mice that had been administered IDENs or vehicle intravenously. NKT cells were cocultured Etoposide manufacturer in vitro with DCs from the livers of untreated mice in the presence of α-GalCer. The results show that the NKT cells purified from the mice that had been administered IDENs had significantly lower production of both IFN-γ and IL-4 of NKT cells to α-GalCer stimulation (Fig. 5C). Liver NKT cells pretreated with circulating exosomes also produce less IFN-γ and IL-4 in response to α-GalCer stimulation (Supporting Fig. 6), suggesting that IDEN-PGE2–mediated induction of NKT cell anergy is physiologically relevant. To further determine whether the IDEN-associated PGE2 played a role in the induction of NKT cell anergy, mice were treated with indomethacin, a cyclo-oxygenase 2 inhibitor that blocks the generation of PGE2. The effects of IDENs isolated from indomethacin-treated mice on the induction of NKT cell anergy were then evaluated. Indomethacin treatment reduced significantly the amounts of PGE2 associated with IDENs (Supporting Fig. 5), which ultimately led to the attenuation of IDEN-mediated anergy induction in NKT cells to α-GalCer stimulation (Fig. 5D).

5 mg/m2/dose D3), followed by a reassessment to determine tumor response. If a partial response was achieved, TACE combined with HIFU was then performed. If unsatisfactory, two more C5VD regimens were subsequently administered for these patients (cisplatin: 100 mg/m2/dose D1; 5-fluorouracil: 600 mg/m2/dose D3; vincristine: 1.5 mg/m2/dose D3; doxorubicin: 10-15 mg/m2/dose D4). No patient needed to be omitted from the study due to the toxicity of doxorubicin. After the patients finished the initial chemotherapy cycles, they underwent CT/MRI examination again. A reassessment was subsequently performed by the Pediatric Oncology team to evaluate the tumor response. It was obvious that

the tumor blood supply was significantly reduced after chemotherapy, and the

margin between ICG-001 the tumor and normal liver was much clearer. The tumor size also decreased after chemotherapy in all patients. Based on the follow-up radiological findings, 6 of 12 patients would be able to undergo a partial hepatectomy after chemotherapy due to the decreased tumor size. However, their parents all refused the surgical procedure, although our team discussed with them Dasatinib in vitro several times how important the hepatectomy is in terms of a cure method for hepatoblastoma. They hoped to continue the trial protocol due to the noninvasive nature of HIFU treatment. After TACE combined with HIFU treatments, all patients received at least four cycles of adjuvant chemotherapy with C5V regimen. The AFP levels decreased steadily

except in one patient with a tumor embolus in the portal vein (patient no. 12). All patients received TACE before HIFU ablation. TACE was performed by two interventional radiologists with the use of the Seldinger technique of arterial embolization described previously.[8] Under general anesthesia, the femoral artery is cannulated using the Seldinger technique and a 4- or 5-F sheath with a hemostatic valve is placed in the groin. Then hepatic arteriography was performed to demonstrate the hepatic arterial branching and size and location of tumor. Dichloromethane dehalogenase According to the size, location, and arterial blood supply of the tumors, either the right or left hepatic artery was catheterized selectively guided by digital subtraction angiography. A 3- to 5-F tracker catheter was catheterized to the feeding arteries of tumors for superselective embolization. The feeding arteries of all tumors were embolized with the use of the suspension mixed with either 100 mg/m2 of Carboplatin (Qilu Pharmaceutical Factory, Jinan, China) or 10-15 mg/m2 of adriamycin (Pfizer, Nerviano, Italy) and 3-8 mL of iodized oil (Lipiodol; Huaihai Pharmaceutical Factory, Shanghai, China). After initial chemotherapy, the tumor size was significantly decreased in all patients. However, there were six patients with lesions in both lobes of the liver.

Conclusion: Oral tacrolimus is a safe and effective therapy for the treatment of moderate to severe UC, although still more longer follow-up of patients and compilation of further clinical data will be necessary. Key Word(s): 1.

ulcerative colitis; 2. tacrolimus Presenting Author: MANABU SHIRAKI Additional Authors: Selleckchem NVP-LDE225 TAKAYUKI YAMAMOTO, KOICHI MATSUMOTO Corresponding Author: MANABU SHIRAKI Affiliations: Yokkaichi Hazu Medical Cener, Yokkaichi Hazu Medical Cener Objective: It has been reported that CT can be used for the evaluation of inflammatory bowel disease; nevertheless, there have been few reports on the efficacy of low dose CT for ulcerative colitis. We report here the efficacy of low dose CT for ulcerative colitis.

Methods: The patients with relapsing ulcerative colitis between Rucaparib July 2013 and April 2014 were included in this study. All patients had undergone sigmoidoscopy and low dose CT scan. The colon CT image was divided into six segments, and then we evaluated wall thickening, stratification, contrast enhancement and mesenteric vascular engorgement, assigning a CT score to each segment. We calculated a total CT score by the sum of CT scores of 6 segments. To assess endoscopic severity, Ulcerative Colitis Colonoscopic Index of Severity (UCCIS) was used. The clinical severity was assessed by Mayo partial score. We investigated the correlation between those CT scores and UCCIS. The correlation between partial Mayo score and total CT score also investigated. Results: Twenty three cases of ulcerative colitis were included in this study. We achieved a 57% reduction of effective dose by adjusting the scan conditions and the reconstruction conditions (P = 0.00326). We observed a high degree of correlation between the sum of the CT scores of the rectum and sigmoid colon and the sum of the UCCIS of the rectum and sigmoid colon (ρ = 0.629). Although the UCCIS of the rectum and sigmoid colon segment calculated by sigmoidoscopy and partial Mayo scores correlate (ρ = 0.456, R2 = 0.267), the correlation analysis between the total CT score and the partial Mayo score indicated a higher coefficient of determination

(ρ = 0.643, R2 = 0.315). Conclusion: This study Afatinib supplier suggested that low dose CT could provide more effective images to assess the disease activity of ulcerative colitis less invasively compared with sigmoidoscopy.

[13] Large-volume paracentesis[14] and transjugular intrahepatic portosystemic shunt (TIPS)[15] are effective if ascites is compromising the child’s respiratory effort and is not responsive to medical therapy. Rapid accumulation of ascites should raise concern for obstruction of the portal or hepatic vein or bacterial peritonitis. Evaluation and management of esophageal varices in children varies widely among practitioners.[16, 17] In the absence of data supporting primary prophylactic therapy for esophageal varices in children, screening endoscopy for esophageal varicies has not been recommended.[18] Inflammatory bowel disease (IBD),

particularly ulcerative colitis, is a notable comorbidity of children PF-01367338 supplier with primary sclerosing cholangitis (PSC). Following

LT, some patients with autoimmune hepatitis and bile salt excretory pump disease are at risk for recurrence of their primary liver disease[19, 20]; those with PSC may also be at increased risk for colon cancer.[21, 22] 8. Clinically detectable ascites can be managed initially with an aldosterone antagonist (2-B); more aggressive removal of ascitic fluid using paracentesis or transjugular intrahepatic portosystemic shunt or surgical shunt should be reserved for ascites that compromises respiratory effort or severely affects quality of life. (2-B) 9. Patients with conditions such as autoimmune hepatitis, PSC, and bile salt excretory pump disease should be informed that liver disease can recur post-LT. (2-B) 10. Patients at risk for EX 527 in vivo extrahepatic complications such as IBD should be informed of the need for scheduled monitoring for evidence of IBD, including colonoscopy, for colon cancer surveillance. (2-B) Children with chronic liver disease are at risk for malnutrition as they require 20%-80% PD184352 (CI-1040) more calories than normal children to achieve adequate growth.[23-25] Increased caloric requirements result from a hypermetabolic state coupled with

malabsorption. Aggressive nutritional support prior to LT improves patient and graft survival as well as neurodevelopmental outcome.[26, 27] Serial triceps skin fold and mid-arm circumference are the most reliable anthropometric assessments to judge nutritional status, as reliance on weight alone may overestimate nutritional adequacy in children with chronic liver disease.[24, 25, 28] Fat soluble vitamin (FSV) deficiency is common and dosing and monitoring recommendations to prevent FSV deficiency are available.[24, 25, 29, 30] Enteral formulas that contain medium chain triglycerides (MCT) are preferred in cholestatic patients, but excessive administration of MCT can lead to essential fatty acid deficiency.[31] Protein intake should not be restricted in the absence of hyperammonemia.[32] When oral intake is not sufficient, initiation of nasogastric (NG) tube feeding improves body composition in children with chronic liver disease.[33] Parenteral nutrition may help reverse poor weight gain and growth in malnourished children with BA.

2 g/dL after 6 months of treatment with BCAA granules as well as a significant increase in the serum albumin level in patients with intake of a poor diet (poor intake of energy).[33] Therapy using BCAA granules also significantly decreased the incidence of ascites even in patients with an unchanged serum albumin Selleckchem Venetoclax level because of qualitative improvement of the serum albumin level (specifically, an increase in the level of reduced albumin and decrease in the level of oxidized albumin).[33-35] The importance of treatment

compliance was suggested in a study conducted by Takaguchi et al.[36] That prospective, large-scale, multicenter, observational study in 2894 patients with decompensated cirrhosis reported that the incidence of cirrhosis-associated events was decreased significantly in patients with good adherence to BCAA treatment compared with those with poor adherence. The

authors emphasized the importance of thorough instruction regarding medications to patients.[36] Dinaciclib concentration The appropriate timing of the initiation of BCAA treatment is controversial. The approved indication of BCAA granules in Japan is for the treatment of decompensated cirrhosis in patients with a serum albumin level of 3.5 g/dL or less, and the Japanese Nutritional Study Group for Liver Cirrhosis has also recommended that BCAA granules should be administrated in cirrhotic patients with a serum albumin level of 3.5 g/dL or less, Fisher’s ratio of 1.8 or less and/or BCAA : tyrosine ratio (BTR) of 3.5 or less.[37] Hence, therapy using BCAA granules is, in general, started when the serum albumin level is 3.5 g/dL or less in clinical settings.[11, 37] However, earlier initiation of BCAA treatment has been attempted in cirrhotic patients with a serum albumin level of 3.6 g/dL or more. Habu et al. classified their patients into four treatment arms based

on their serum albumin level and the BTR.[38] The decrease in the serum albumin level was inhibited after therapy using BCAA granules even in patients with a serum albumin level of 3.6 g/dL or more if their BTR was 4 or less, so the authors Vildagliptin highlighted the usefulness of early intervention with BCAA granules.[38, 39] A prospective, multicenter study in Japanese patients with hepatitis C virus-related decompensated cirrhosis with a serum albumin level of 3.6 g/dL or more complicated with insulin resistance (BCAA Granules for patients with Hepatitis C virus-related Liver Cirrhosis and Insulin Resistance on the Effect of Reduction of Carcinogenic Risk in the Liver [BLOCK] study, Japan Liver Oncology Group [JLOG] 1004 Trial) is ongoing. If the superiority of therapy using BCAA granules is demonstrated in that study, BCAA granules will become available for a wider range of cirrhotic patients. As mentioned above, BCAA granules can inhibit hepatic carcinogenesis.

Each hour of delay in appropriate antimicrobial therapy was associated with an 86% increase in the odds of in-hospital mortality.

Admission APACHE II and serum lactate also significantly impacted mortality. Earlier identification of septic shock and initiation of appropriate antimicrobial therapy could potentially improve outcomes.

Aims: To evaluate AZD1208 manufacturer the association of procalcitonin (PCT) with acute-on-chronic liver failure (ACLF) or death in patients with SBP. Methods: Adult cirrhotic patients with SBP were prospectively included from

October 2012 to March 2014 in 3 Liver Units. Patients with a prior episode of ACLF (CLIF-Consortium) in the 30 days before the inclusion and patients with end-stage hepa-tocellular carcinoma, organ transplantation, immunosuppres-sion or active alcohol drinking were excluded. Procalcitonin (measuring range: 0.02-100 ng/mL) was collected at the time of SBP diagnosis and before antibiotic initiation. Investigators were blinded to PCT results. Primary outcome was ACLF or death at 30 days of SBP diagnosis. see more Results: Forty one consecutive patients with SBP were included. Overall, ACLF was diagnosed in 27 (66%) patients, 11 (27%) died. In the univariate analyses, patients with ACLF or death had significantly higher PCT, Child-Pugh score, MELD, INR and creatinine than patients without ACLF or death (Table). The OR for ACLF or death for every

0.1 ng/mL increase of PCT was 1.34 (CI 95% 1.071.67, p 0.01). After adjusting for age, MELD, creatinine and positive blood cultures, the OR was 1.75 (CI 95% 1.05-2.93, p 0.033). From a receiver operating characteristic curve, a PCT cut-off point of 0.95 ng/mL was identified with Adenosine triphosphate sensitivity 67% and specificity 100% for predicting ACLF or death. Positive and negative predictive values were 100% and 61%, respectively. Conclusion: In patients with SBP, PCT is a strong predictor of bad outcomes. A PCT of > 0.95 ng/mL at diagnosis of SBP identifies patients at high risk of ACLF or death. *Median (IQR), **Mean ± SD, *** Hepatocellular Carcinoma, **** Systemic Inflammatory Response Syndrome.

From August 2004 to January 2008, 132 consecutive patients with HCV recurrence after LT out of a total of 293 patients who underwent transplantation in our GPCR Compound Library molecular weight institution

were considered for the study. Exclusion criteria were: graft or patient survival shorter than 12 months after LT (n = 17); combined kidney and liver transplantation (n = 4); hepatitis B virus or human immunodeficiency virus coinfection (n = 3); presence of ascites (n = 6), body mass index > 33 (n = 2), chronic graft rejection (n = 5), biliary tract complications (n = 8), veno-occlusive disease this website (n = 1), de novo autoimmune hepatitis (n = 1) and recurrence of hepatocellular carcinoma (n = 1) during the first year after LT. Therefore, the final number

of HCV-infected LT recipients included was 84 (64%). Another 19 patients who underwent LT for other etiologies were included as the control group. Patients were managed according to previously published protocols.28 Induction immunosuppression was cyclosporine A or tacrolimus and prednisone. Mycophenolate mofetil was added in patients who required cyclosporine or tacrolimus dose reduction or discontinuation. Immunosuppression therapy was recorded throughout the study. Acute rejection episodes were documented by liver histologic analysis and treated with steroid boluses if moderate or severe. After discharge,

patients were visited at the outpatient clinic, monthly for the first 3 months with complete recording of clinical and analytical variables, and every 2 or 3 months thereafter. A total of 73 HCV-infected LT recipients underwent repeated LSM at 3, 6, 9, and 12 months and a liver Forskolin purchase biopsy 1 year after LT (median = 12.3 months). An HVPG measurement was available in 65 patients at the same time. The remaining 11 patients had cholestatic hepatitis.29 In these patients, liver biopsy (n = 11) and HVPG (n = 9) were performed when the clinical diagnosis was suspected (median = 6.7 months). LSM before initiation of antiviral treatment were available at 3 and 6 months in eight patients and at months 3, 6, and 9 in three. Another five non–HCV-infected patients with elevated alanine aminotransferase (≥ 40 IU/L) underwent a liver biopsy 1 year after LT (median = 13.4 months). The study was previously approved by the Investigation and Ethics Committee of the Hospital Clinic of Barcelona following the ethical guidelines of the 1975 Declaration of Helsinki.
