Objective: We aimed to compare the response rates between two different hepatitis B virus vaccination schedules for cirrhotic subjects who were non-responders to the first three 40 µg doses (month 0-1-2), and identify factors associated with the final response., Design: A total of 120 cirrhotic patients (72.5% decompensated) were randomised at a 1:1 ratio to receive a single 40 µg booster vaccination at month 6 (classical arm) versus an additional round of three new 40 µg doses administered at monthly intervals (experimental arm). The main outcome was the rate of postvaccinal anti-hepatitis B surface antibodies levels ≥10 mIU/mL., Results: Efficacy by ITT analysis was higher in the experimental arm (46.7%) than in the classical one (25%); OR 2.63, p=0.013. The experimental arm increased response rates compared with the classical one from 31% to 68% (OR 4.72; p=0.007), from 24.4% to 50% (OR 3.09; p=0.012) and from 24.4% to 53.8% (OR 3.62; p=0.007), in Child A, Model for End-Stage Liver Disease (MELD) <15 and MELD-Na<15 patients, respectively. Patients with more advanced liver disease did not benefit from the reinforced scheme. Both regimens showed similar safety profiles. Multivariable analysis showed that the experimental treatment was independently response associated when adjusted across three logistic regression models indicating equivalent cirrhosis severity., Conclusion: For cirrhotic patients, the revaccination of non-responders to the first three dose cycle, with three additional 40 µg doses, achieved significantly better response rates to those obtained with an isolated 40 µg booster dose., Trial Registration Number: NCT01884415., Competing Interests: Competing interests: ÁG-G has received speaker fees from Gilead, Gore, MSD, BMS and Abbvie.

Objectives: To investigate resistance-associated substitutions (RASs) as well as retreatment efficacies in a large cohort of European patients with failure of glecaprevir/pibrentasvir., Methods: Patients were identified from three European Resistance Reference centres in Spain, Italy and Germany. Sequencing of NS3, NS5A and NS5B was conducted and substitutions associated with resistance to direct antiviral agents were analysed. Clinical and virological parameters were documented retrospectively and retreatment efficacies were evaluated., Results: We evaluated 90 glecaprevir/pibrentasvir failures [3a (n = 36), 1a (n = 23), 2a/2c (n = 20), 1b (n = 10) and 4d (n = 1)]. Ten patients were cirrhotic, two had previous exposure to PEG-interferon and seven were coinfected with HIV; 80 had been treated for 8 weeks. Overall, 31 patients (34.4%) failed glecaprevir/pibrentasvir without any NS3 or NS5A RASs, 62.4% (53/85) showed RASs in NS5A, 15.6% (13/83) in NS3 and 10% (9/90) in both NS5A and NS3. Infection with HCV genotypes 1a and 3a was associated with a higher prevalence of NS5A RASs. Patients harbouring two (n = 34) or more (n = 8) RASs in NS5A were frequent. Retreatment was initiated in 56 patients, almost all (n = 52) with sofosbuvir/velpatasvir/voxilaprevir. The overall sustained virological response rate was 97.8% in patients with end-of-follow-up data available., Conclusions: One-third of patients failed glecaprevir/pibrentasvir without resistance. RASs in NS5A were more prevalent than in NS3 and were frequently observed as dual and triple combination patterns, with a high impact on NS5A inhibitor activity, particularly in genotypes 1a and 3a. Retreatment of glecaprevir/pibrentasvir failures with sofosbuvir/velpatasvir/voxilaprevir achieved viral suppression across all genotypes., (© The Author(s) 2020.

Objective: The objective of this study was to determine the long-term clinical outcome and persistence of hepatitis B surface antigen (HBsAg) loss after discontinuation of treatment., Background: The prognosis of patients with chronic hepatitis B (CHB) treated with nucleos(t)ide analogues (NAs) who discontinue treatment after loss of HBsAg remains largely unknown, particularly in White patients., Patients and Methods: We analysed a cohort of patients with CHB who discontinued NA treatment after loss of HBsAg. A total of 69 patients with hepatitis-B-e antigen-positive or hepatitis-B-e antigen-negative CHB with undetectable HBsAg during NA treatment were included after discontinuation of treatment, and followed up for a median period of 37.8 months (interquartile range: 23.8-54.6 months)., Results: At the end of follow-up, none of the patients showed spontaneous reappearance of HBsAg and only one patient had detectable hepatitis B virus DNA (22 IU/ml). Another patient negative for HBsAg and anti-HBs developed hepatitis B virus reactivation without elevated transaminases after treatment with corticosteroids and vincristine for dendritic cell neoplasm, 38 months after withdrawal of the antiviral treatment. Regarding clinical outcome, a patient with cirrhosis developed hepatocellular carcinoma, 6.6 years after discontinuing treatment. None of the patients had hepatic decompensation or underwent liver transplantation., Conclusion: HBsAg clearance after discontinuing NAs in patients with CHB is persistent and associated with good prognosis. The risk for developing hepatocellular carcinoma persists among patients with cirrhosis.

Background & Aims: In phase 3 trials and real-world settings, smaller proportions of patients with genotype 3 hepatitis C virus (HCV) infection and cirrhosis have a sustained virologic response 12 weeks after treatment (SVR12) with the combination of sofosbuvir and velpatasvir than in patients without cirrhosis. It is unclear whether adding ribavirin to this treatment regimen increases SVRs in patients with genotype 3 HCV infection and cirrhosis., Methods: We performed a phase 2 trial of 204 patients with genotype 3 HCV infection and compensated cirrhosis (mean age 51 ± 7.4 years) at 29 sites in Spain from August 19, 2016 through April 18, 2017. Patients were assigned to groups given sofosbuvir and velpatasvir for 12 weeks (n = 101) or sofosbuvir and velpatasvir plus ribavirin for 12 weeks (n = 103). The primary efficacy end point was SVR12., Results: The overall rates of SVR12 were 91% (92 of 101; 95% CI 84-96) for the sofosbuvir-velpatasvir group and 96% (99 of 103; 95% CI 90-99) for the sofosbuvir-velpatasvir plus ribavirin group. In the sofosbuvir-velpatasvir group, a smaller proportion of patients with baseline resistance-associated substitutions (RASs) in nonstructural protein 5A (NS5A) achieved an SVR12 (84%) than did patients without (96%). In the sofosbuvir-velpatasvir plus ribavirin group, baseline RASs had less effect on the proportion of patients with an SVR12 (96% for patients with baseline RASs; 99% for patients without). The most common adverse events (which occurred in ≥10% of patients) were asthenia (12%) in the sofosbuvir-velpatasvir group and asthenia (27%), headache (24%), and insomnia (12%) in the sofosbuvir-velpatasvir plus ribavirin group., Conclusions: Consistent with findings from previous studies, a high rate of patients (91% and 96%) with genotype 3 HCV infection and compensated cirrhosis achieved an SVR12 with sofosbuvir and velpatasvir, with or without ribavirin. Of patients treated with sofosbuvir and velpatasvir without ribavirin, fewer patients with baseline NS5A RASs achieved an SVR12 compared with patients without baseline NS5A.

Background and Aims: Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and real-world clinical practice, showed high rates of sustained virological response (SVR) in non-cirrhotic genotype (GT)-1 and GT-4 patients. These results were slightly lower in cirrhotic patients. We investigated real-life effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients., Methods: This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCV-GT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between January-2014 and December-2015. Demographic, clinical, virological and safety data were analysed., Results: Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELD≥10) or portal hypertension (platelet count≤100×10 9 /L, transient elastography≥21 Kpa) showed significantly lower SVR rates (84.4%-91.9%) than patients with less advanced liver disease (93.8%-95.9%, P<.01 in all cases). In the multivariate analysis, the use of RBV, female gender, baseline albumin≥35 g/L, MELD<10 and lack of exposure to a triple therapy regimen were independent predictors of SVR (P<.05). Serious adverse events (SAEs) and SAE-associated discontinuation events occurred in 5.9% and 2.6%., Conclusions: In this large cohort of cirrhotic patients managed in the real-world setting in Spain, SOF/SMV±RBV yielded to excellent SVR rates, especially in patients with compensated liver cirrhosis. In addition, this combination showed to be safe, with low rates of SAEs and early discontinuations., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background & Aims: Patients with hepatocellular carcinoma (HCC) submitted to orthotopic liver transplantation (OLT) have a variable 5-year survival rate limited mostly by tumor recurrence. The etiology, age, sex, alcohol, Child-Pugh, and the immunesuppressor have been associated with tumour recurrence. The expression of ΔNp73 is related to the reduced survival of patients with HCC. The study evaluated the expression of p63 and p73 isoforms and cell death receptors, and their relation to tumour recurrence and survival. The results were in vitro validated in HCC cell lines., Methods: HCC sections from patients submitted to OLT were used. The in vitro study was done in differentiated hepatitis B virus (HBV)-expressing Hep3B and control HepG2 cells. The expression of cell death receptors and cFLIPS/L, caspase-8 and -3 activities, and cell proliferation were determined in control and p63 and p73 overexpressing HCC cells., Results: The reduced tumor expression of cell death receptors and TAp63 and TAp73, and increased ΔNp63 and ΔNp73 expression were associated with tumor recurrence and reduced survival. The in vitro study demonstrated that HBV-expressing Hep3B vs HepG2 cells showed reduced expression of p63 and p73, cell death receptors and caspase activation, and increased cFLIPL/cFLIPS ratio. The overexpression of TAp63 and TAp73 exerted a more potent pro-apoptotic and anti-proliferative effects in Hep3B than HepG2-transfected cells which was related to cFLIPL upregulation., Conclusions: The reduction of TAp63 and TAp73 isoforms, rather than alteration of ΔN isoform expression, exerted a significant functional repercussion on cell death and proliferation in HBV-expressing HepB cells.

Background and Aims: Rapid viral response (RVR) during antiviral treatment for hepatitis C virus (HCV) predicts sustained viral response (SVR). Recently, vitamin D levels have been associated with SVR. As sunlight is the most important source of vitamin D and shows seasonal variation, we evaluated the effect of season on viral kinetics during peginterferon/ribavirin-based therapy for HCV., Methods: Consecutive HCV patients treated with peginterferon/ribavirin and boceprevir/ telaprevir (June 2011-July 2014) were included. Patients were grouped according to season when therapy was initiated (Season A: May-October and Season B: November-April) depending on hours of daily sunlight. Multiple logistic regression analysis included factors known to influence SVR to treatment. The dependent variables were undetectable viral load (VL) or VL ≤15 UI/mL (VL ≤15) at weeks 4, 8 and 12, end of treatment and SVR., Results: The study included 930 patients (66.8% men; median 54 years) treated with telaprevir (n=537) or boceprevir, without (n=481) or with lead-in therapy of peginterferon/ribavirin. Baseline characteristics of patients in Season A (45.3%, n=421) and Season B groups were similar. Overall, a higher rate of RVR (23.5% vs 16.1%, p=0.005) and VL ≤15 (51.0% vs 38.6%, p≤0.001) was observed in patients starting treatment during Season A versus Season B. By logistic regression analysis, initiating treatment in Season A proved to be an independent predictor of RVR and VL ≤15., Conclusions: In our setting, seasonality affects viral kinetics in HCV genotype 1 patients treated with peginterferon/ribavirin-based therapy. Our findings support the hypothesis that vitamin D influences viral response to peginterferon/ribavirin-based therapy., Competing Interests: Competing interests: None declared.

Hepatopulmonary syndrome (HPS) is characterized by abnormalities in blood oxygenation caused by the presence of intrapulmonary vascular dilations (IPVD) in the context of liver disease, generally at a cirrhotic stage. Knowledge about the subject is still only partial. The majority of the information about the etiopathogenesis of HPS has been obtained through experiments on animals. Reported prevalence in patients who are candidates for a liver transplantation (LT) varies between 4% and 32%, with a predominance of mild or moderate cases. Although it is generally asymptomatic it does have an impact on their quality of life and survival. The diagnosis requires taking an arterial blood gas sample of a seated patient with alveolar-arterial oxygen gradient (AaO2) ≥ 15 mm Hg, or ≥ 20 mm Hg in those over 64 years of age. The IPVD are identified through a transthoracic contrast echocardiography or a macroaggregated albumin lung perfusion scan ((99m)Tc-MAA). There is currently no effective medical treatment. LT has been shown to reverse the syndrome and improve survival rates, even in severe cases. Therefore the policy of prioritizing LT would appear to increase survival rates. This paper takes a critical and clinical look at the current understanding of HPS, as well as the controversies surrounding it and possible future research.

The most common hepatopathy in end-stage renal disease is chronic hepatitis C virus (HCV) infection, which decreases allograft and patient survival in kidney transplants. Until last year we did not have treatments free of interferon, which was contraindicated after renal transplantation owing to the risk of allograft rejection. Recently, new drugs have been discovered for interferon-free regimens. These drugs present a cure rate of up to 90% and can be used in transplant recipients. Here we present our 1st 3 cases. In our experience, new antivirals have proven to be effective and safe for the treatment of HCV hepatopathy in kidney transplant recipients and liver-kidney transplantation, thus helping us to prevent complications related to HCV infection in transplant recipients., (Copyright © 2015 Elsevier Inc.

Objectives: To perform a prospective analysis of changes in liver stiffness (LS) using transient elastography (TE) in a consecutive series of patients with post-liver transplant (LT) recurrent hepatitis C, either left to their natural evolution or receiving antiviral treatment., Methods: We examined the results from 17 comparisons of TE (baseline vs follow-up) from 11 patients. We evaluated: (1) upon inclusion in the study: age, sex, genotype, time transpired since LT, and baseline fibrosis (F0-4; Scheuer), and (2) during the follow-up period: time elapsed between the two TE and either specific treatment (B) or absence of treatment (A)., Results: Mean patient age was 56.8 ± 7.9 years, with a male/female ratio of 10:1. Ten of the eleven patients had genotype 1b. The median time transpired between the LT and inclusion in the study was 28 months (range: 6-142 months). The mean time transpired between the two TE was 11.3 ± 4.5 months. In the 11 patients from group A (9 F1/2 F2; 13 "paired" TE), a predictable increase in LS was produced in 10 cases and a paradoxical result was produced in 3 cases. In the four patients in group B (3 F2/1 F1; 4 "paired" TE), a decrease in LS was produced in 3 cases and a paradoxical result in 1 case., Conclusions: In our study of patients left to their natural evolution, a slow increase of LS was normal. However, antiviral treatment appeared to decrease LS. TE can be very useful as a complementary test to biopsy for monitoring post-LT recurrent hepatitis C. A longer follow-up period and larger sample size could confirm these preliminary results., (Copyright © 2012 Elsevier Inc. All rights reserved.)

In the absence of immunity, vaccination against hepatitis A virus (HAV) and hepatitis B virus (HBV) is recommended for patients with chronic liver disease and those evaluated for liver transplantation (OLT) HAV and HBV infections after OLT which are frequent in this setting, are associated with a worse prognosis. The aim of this study was to estimate the need for vaccination against HBV and HAV among cirrhotic patients who were candidates for OLT and associations with gender, age, and etiologic factors. HBV and HAV serological markers HBsAg, anti-HBc, antiHBs, immunoglobulin G (IgG)-anti-HAV were investigated among 568 patients, including 75% men. The overall mean age was 53.6 ± 8.9 years range 17-69, and 20% were diabetic. This etiologies were alcohol (68%), hepatitis C virus (35%) or other causes (10.4%). Child-Pugh classes were: A (26%), B (44%), and C (30%). In contrast with 359 patients (63.2%) who had negative HBV markers, 209 (36.8%) were positive: HBsAg (+), 43 (7.6%), isolated anti-HBc (+), 57 (10%), isolated anti-HBs (+), 19 (3.3%), anti-HBc (+)/anti-HBs (+), 90 (15.8%). HBV vaccine indication was performed in 416 patients (73.2%) who either had negative HBV markers or isolated anti-HBc (+). It was more frequently performed in women (82.3% versus 70.3%, P = .005), albeit with no differences according to age or etiology. There were only 8.2% (44/538) IgG-anti-HAV-negative, an indication for vaccination against HAV, which was more frequent affecting patients who were younger [≤ 45 years (27.6%), 46-55 (7.2%), >55 (2.6%); P < .0001)]; nondiabetic (9.5% versus 2.8%, P = .023); nonalcoholic (11.4% versus 6.6%, P = .056); and displayed negative HBV markers (10.2% versus 4.6%, P = .023). Only three patients with IgG-anti- HAV (-) were over 60 years. In conclusion, there is a frequent indication for HBV vaccination among cirrhotic and especially HAV vaccine for under 45 year old patients undergoing evaluation for OLT., (Copyright © 2012 Elsevier Inc.

We performed a retrospective study to evaluate the rate of and factors associated with a response to recombinant hepatitis B virus (HBV) vaccination using 4 intramuscular doses (40 μg) administered at 0, 1, 2, and 6 months among 278 cirrhotic patients being evaluated for orthotopic liver transplantation (OLT). We re-vaccinated 57 non-responders with the same schedule. The 39.2% overall response rate to vaccination included 36% after three and 40.7% after four doses, namely, a median anti-HBs level of 100 IU/mL (range, 10 to 1000 IU/mL). The 51% revaccination response rate achieved a median hepatitis B surface antibody (anti-HBs) level of 99 IU/mL (range, 11 to >1000 IU/mL). Upon univariate analysis, variables associated with a higher response were: better liver function (Child-Pugh class [A, 53.8% B, 33.3%, C, 30.1%; P = .002), Model for End-stage Liver-Disease (MELD) score (11.4 versus 13.6; P = .001]), absence of diabetes (43.6% versus 20.8%; P = .002), presence of isolated hepatitis B core antibody (anti-HBc) positivity (80% versus 37.7%; P = .007), and younger age (< 45 years, 52.2%; range, 45 to 55 years, 40.4%; > 55 years, 34.1%; P = .031). Upon multivariate logistic regression analysis, lower MELD score (odds ratio [OR]: 0.922; P = .046), absence of diabetes (OR:0.359; P = .008) and isolated anti-HBc positivity (OR:5.826; P = .034) were associated with a higher response. No differences were observed to be associated with gender, weight, body mass index, etiology or tobacco consumption. Among the same patient cohort (n = 79), the responses after the third and fourth doses were 36.7% and 51.9% respectively. In conclusion, the response rate to HBV vaccination in cirrhotic patients evaluated for OLT reached more than 35% among those who received at least 3 doses. It was higher among patients who showed isolated anti-HBc positivity, better liver function, younger age, and non-diabetic status. The fourth dose only increased the response rate by 24% over that obtained after the first three doses, whereas a revaccination achieved a 50% response rate, which probably accounts for revaccination after no response to 3 doses. Vaccination should be introduced against HBV in the early stages of the disease., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Background: We performed a retrospective study to examine the prevalence of bone disease (BD) among cirrhotic patients being evaluated for liver transplantation (OLT) using bone densitometry dual-energy x-ray absorptiometry in the hip/femoral neck and lumbar spine. The associations of BD with demographic and clinical data, disease etiology and liver function were studied by univariate and multivariate logistic regression analyses. Osteopenia and osteoporosis were defined by World Health Organization criteria., Results: We included 486 patients (79% men of mean age, 53 ± 8.8 years (range, 21-69) who included 62.6% smoker and 23.7% diabetic subjects. Body mass index (BMI) was 28.8 ± 5.7 kg/m(2) (range, 16-43). The liver disease was Child-Pugh class A (22%), B (51%), or C (27%); the Model for End-Stage Liver Disease (MELD) score was 14.6 ± 5.4 (range, 7-33). The disease etiology was alcohol (59%), hepatitis C (32%), hepatitis B (10%), primary biliary cirrhosis (PBC) (2.3%), secondary biliary cirrhosis, (2%) or other causes (10%). In all, 350 patients (72%) had BD in the hip/femoral neck and/or lumbar spine: Global hip, 26% (osteopenia, 22%; osteoporosis, 4%); femoral neck, 48% (osteopenia, 43%; osteoporosis, 5%) and lumbar spine, 63% (osteopenia, 40%; osteoporosis, 23%). Univariate analysis showed the BD risk to increase with the following variables: Female gender (odds ratio [OR], 1.88; P = .023) and lower BMI (OR, 0.95; P = .012). Upon multivariate analysis, female gender (OR, 2.43; P = .004), lower BMI (OR, 0.96; P = .016), and tobacco use (OR, 1.59; P = .043) were significant. PBC showed BD in 100% of cases. By adjusting bone mineral density (BMD) values to age (Z-score) in relation to that defined by T-score, we observed a decrease in BD prevalence in both the femoral neck (20% vs 48%) and the lumbar spine (44% vs 63%)., Conclusion: BD, especially in the lumbar spine, is common among cirrhotic patients under evaluation for OLT. Cirrhosis is a major BD risk factor that remains even when BMD values are adjusted for age. Female gender, lower BMI, and tobacco consumption are major risk factors for BD in cirrhotic patients. Bone densitometry must be included in the OLT evaluation of all patients., (Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.)

Objective: To assess the efficacy and safety of mycophenolate mofetil (MMF) monotherapy in liver transplant recipients with renal failure secondary to the use of calcineurin inhibitors (CNIs)., Materials and Methods: Thirty-one patients on MMF monotherapy with creatinine levels >1.3 mg/dL, previously immunosuppressed with CNIs and MMF, were analyzed. Conversion was started in patients with no acute or chronic rejection episodes and stable liver chemistry. CNI doses were reduced by 25% every 2 to 3 months, or to 50% if the dose was lower than 1 mg/d of tacrolimus or 50 mg/d of cyclosporine. Different variables were recorded from the time that conversion to monotherapy was decided, on the discontinuation day of the calcineurin inhibitor, and during the follow-up., Results: Mean times from transplant to conversion ranged from 14 to 186 months. The minimum follow-up time in monotherapy was 12 months. Renal function improved at 6 months in 70% of cases and at 12 months in 69.6%. Patients with no renal function improvement maintained stable creatinine values. There were no rejection episodes, graft losses, or deaths. No leukopenia occurred, and triglyceride and uric acid values improved., Conclusions: MMF monotherapy is a safe alternative in patients with posttransplant renal failure secondary to the use of CNIs. Renal function improvement was achieved in almost 70% of patients at 12 months, and creatinine values were maintained in all other patients. The risk of rejection due to the slow tapering of CNIs is minimum.

Unlabelled: Our objective was establish a scoring system that allows a donor to be evaluated quickly and easily using a set of variables that are evaluated prior to the donation and another set that are evaluated during surgery., Materials and Methods: Prior to the donation we analyzed age, medication requirements, natremia, hepatic biochemistry, gas levels, days in ICU, history of hypertension, and weight. A value of 40% was allocated to this group of factors. During the transplant we assessed the characteristics of the organ-shine, consistency, surface, edge, color, presence of steatosis, and atheromatosis. A value of 60% was allocated to this set. We established a scale of 1 to 10, only accepting organs scoring 5 or more points. Those grafts that received a score between 5 and 7.5 points were called suboptimal and those with over 7.5 points, optimal. We prospectively analyzed 133 donors whose organs were implanted., Results: The survival rate at 1 year was 85%, and the rejection rate was 12%. The incidence of primary graft dysfunction was 8.2% (n = 11) and that of primary graft nonfunction 2.2% (n = 3). The incidence of primary graft dysfunction was greater within the group with fewer points (suboptimal). There were no differences between the optimal and suboptimal groups in terms of primary malfunction, survival, or rejection rate., Conclusions: The score provided a guide to decide whether to accept viable organs for implantation, given that the point system was obtained quickly and easily. When greater than 5, it correlated with low rates of primary nonfunction (<3%) and of primary graft dysfunction (<15%), with acceptable survival at 1 year (>80%) and acute rejections rate (<15%).

Aims: To report our experience with mycophenolate mofetil (MMF) for induction and maintenance therapy to prevent acute liver transplant rejection., Methods: A retrospective analysis of 66 elective, noncombined liver transplant patients treated beginning de novo MMF and follow for a minimum of 2 years. Thirty-nine of the 66 cases received MMF, calcineurin inhibitors, and steroids. In 11 cases daclizumab was added; in 16 daclizumab was added without steroids., Results: The global survival rate was 91% at 6 months, 89.4% at 1 year, and 87.9% after 2 years. Acute rejection episodes were observed in six patients (9.1%). All episodes responded to corticoids. Toxicity possibly, probably, or partially related to MMF was observed in 35 patients (53%) with definitive suspension required in 13 cases (20%), with dose reduction or temporary suspension in 22 (33%). Hematological toxicity associated with MMF was observed in 12 patients (18%), leading to definitive suspension in two patients (3.03%), temporary suspension in two cases (3.03%), and dose reduction in eight cases (12%). Opportunistic infection was observed in seven cases (10%). Gastrointestinal toxicity was mild and infrequent (five cases, 7.5%)., Conclusion: Regimens containing MMF reduce rejection episodes with high survival rates and low toxicity.

Objective: To assess broad antral cytologic brushing as an alternative approach for the diagnosis of Helicobacter pylori gastric colonization as compared to histology., Study Design: Multiple gastric biopsies were taken from the antrum of 117 patients with an endoscopic appearance compatible with antral gastritis. Broad antral brushing was also obtained, and smears were stained with Papanicolaou stain., Results: Chronic gastritis was diagnosed histopathologically in 93 patients. H pylori was identified in 115 cytologic smears. Cytologic smears from 97 patients with H pylori on biopsy specimens contained the organisms. Only two poor-quality cytologic smears with no H pylori had the organisms on biopsy specimens. In 18 patients, H pylori was identified on the cytologic smears and not on the biopsy specimens., Conclusion: Broad antral cytologic brushing is a useful alternative approach to histology for the diagnosis of H pylori gastric infection.

The case of a giant trichobezoar of 2.500 g in weight observed in a 26-year old woman with paranoid disorder which led her to trichophagia is presented. A review of the literature was carried out with the different etiopathogenic theories and proposed treatments being discussed.

We describe three cases of sudden severe retinopathy in patients with acute pancreatitis. The relative times of the organ manifestations and comparisons with other published cases strongly suggest that pancreatitis was the cause of the retinal changes. This systemic complication is unknown to most physicians, but approximately 35 cases have been published. The pathogenesis is not well known. We briefly discuss the significance of this complication and several possible pathogenetic mechanisms.

We present a patient with celiac sprue in whom intestinal lymphoma was suspected. At laparotomy, a brown discolouration of small bowel loops was observed, and a transmural biopsy confirmed a brown bowel syndrome, an entity that is found in long-standing malabsorption conditions. We believe that the intestinal disorder caused by deposition of lipofuscin in the bowel non-striated muscle may cause radiologic changes similar to those seen in intestinal lymphoma.
