Abstract
BACKGROUND AND PURPOSE Neurological manifestations have been identified in the context of autoimmune hepatitis (AIH). Previous case reports highlighted the association between AIH and sensory neuronopathy (SN). Despite that, little is known about the frequency of AIH-related SN and its clinical/neurophysiological profile. Moreover, it is not clear whether SN is an AIH-specific manifestation or related to chronic liver damage. METHODS Seventy consecutive AIH patients were enrolled and their characteristics were compared with 52 consecutive patients with chronic active hepatitis B. All subjects underwent clinical and neurophysiological evaluation. Further comparisons were performed between AIH SN and AIH non-SN patients. RESULTS Mean ages and male:female proportions in the AIH and chronic active hepatitis B groups were 42.2 ± 16.3/51.7 ± 13.6 years and 14:56/29:23, respectively. The frequencies of carpal tunnel syndrome, radiculopathy and polyneuropathy were similar between groups. In contrast, SN was identified only in AIH patients (5/70 vs. 0/52, P = 0.04); the overall prevalence of AIH-related SN was 7% with an average profile of a woman in her 40s with asymmetric onset of sensory deficits that chronically evolved to disabling proprioceptive ataxia associated with marked dysautonomia. Neurological disability and hepatocellular damage did not follow in parallel. Anti-fibroblast growth factor receptor type 3 antibodies were found in 3/5 (60%) of the patients with AIH-related SN. Clinical or demographic predictors of SN in the context of AIH could not be identified. CONCLUSION Sensory neuronopathy, but not other peripheral nervous system diseases, is a specific AIH neurological manifestation. It is often disabling and, in contrast to hepatocellular injury, does not respond to immunosuppression.

Abstract
Recurrent hepatitis C (HCV) after liver transplantation (LT) is an important cause of morbidity and mortality. Antiviral treatment is recommended to avoid unfavorable outcomes. Direct-acting antivirals (DAA) have transformed HCV treatment, with higher efficacy and fewer side-effects than interferon-based therapies traditionally used. To evaluate DAA treatment outcomes at a Brazilian transplant unit, data of patients who finished HCV treatment at the Liver Transplant Unit of the University of Campinas were analyzed. Treatment consisted of sofosbuvir, daclatasvir, and ribavirin, for 12 or 24 weeks, according to the national guidelines. Fifty-five patients completed antiviral treatment and 54 had HCV-viral load results available. The majority of patients were male (78%), 58 years old on average, 65% had hepatocellular carcinoma (HCC) before LT, and 67% were interferon treatment-experienced. Most patients had HCV genotype 1 (65%), 35% had genotype 3, and started treatment on an average of 38 months after LT (range: 2–228). Fifty-eight percent were treated for 12 weeks and 42% for 24 weeks, using a mean dose of ribavirin of 10.1 mg/kg (4.2–16.1). There were no treatment interruptions due to serious side effects. The sustained virological response rate was 98%. Only one patient relapsed, a genotype 3 cirrhotic treated for 12 weeks. The average follow-up after starting antivirals was 20 months. There were no recurrences of HCC, but there was one rejection episode and one cirrhosis decompensation episode, both 12 weeks after treatment. DAA treatment is safe and effective in the post-LT setting and was not associated to HCC recurrence in the cohort studied.

Abstract
Vibration-controlled transient elastography (VCTE) is widely used for noninvasive fibrosis staging in chronic hepatitis C. However, internal validation is based solely on variability and success rate and lacks reproducible quality indicators. We analysed the graphic representation of shear wave propagation in comparison with morphometric results of liver biopsy, eliminating observer variability bias. Individual elastograms were classified according to two morphologic criteria: extension of wave propagation (length of the graphic representation) and shear wave dispersal (level of parallelism displayed in the elastogram). Then, a score based on these criteria stratified the elastogram in classes I through III (highest to lowest technical quality). Liver stiffness results of each measurement were compared with collagen contents in liver biopsy by morphometric analysis. A total of 3243 elastograms were studied (316 patients). Digital morphometry in liver biopsy showed significant fibrosis in 66% of samples and advanced fibrosis in 31%. Elastogram quality analysis resulted in 1438 class I measurements (44%), 1070 class II (34%) and 735 class III. Area under the receiver operating curve (AUROC) for severe fibrosis according to class (I, II and III) was 0.941, 0.887 and 0.766, respectively. For advanced fibrosis, AUROCs were 0.977, 0.883 and 0.781, respectively. Spearman's correlation testing for all classes and levels of fibrosis demonstrated significant independent association (r2 = -.95, P < .01). Our study is the first to propose measurable quality criteria for VTCE and to validate them against objective assessment of liver biopsy through digital morphometric imaging analysis. We concluded that VCTE performance is significantly influenced by quality assessment of individual measurements. Considering these criteria in clinical practice may improve accuracy.

Abstract
Basiliximab is considered to be effective in preventing cellular rejection (CR) in solid organ transplantation and is commonly used for renal transplants. The aim of this study was describe the population of patients undergoing orthotopic liver transplantation (LT) receiving basiliximab in the period 2012-2016 in the liver transplant service at the State University of Campinas, São Paulo, Brazil. We analyzed 114 patients who underwent LT and received basiliximab; 83 (72.8%) were male and 31 (27.2%) female, with an overall mean age of 54.3 years. Immunosuppression was performed with corticosteroids during anesthetic induction, and postoperatively with tacrolimus in 85.5%, sodium mycophenolate in 81.7%, cyclosporine in 12.7%, and everolimus in 15.5% of patients. CR was observed in 25.43% of patients, confirmed by biopsy in 15 patients: 50% acute CR, 21.42% late acute CR, and 28.57% chronic CR. Thus, the data are consistent with the literature regarding the benefit of using basiliximab as induction therapy while reducing the incidence of CR after LT, but on univariate analysis to evaluate factors associated with the occurrence of CR, the analyzed variables did not present statistical significance. There was acute renal failure (ARF) in 46.84% of patients and hemodialysis was performed in 20% of cases. In a previous series in our service, there was an ARF rate of 50%, so the incidence reduction of ARF after basiliximab use was 3.16%. Moreover, there was 6.95% hepatic artery thrombosis, 2.6% portal vein thrombosis, 2.6% biliary fistulas, 17.4% pneumonia, and 3.4% sepsis, which did not differ from the literature or from our earlier study without the use of basiliximab, suggesting the safety of this medication. In conclusion, in this series, basiliximab influenced the decrease of the CR incidence with no proven benefit on improvement in the ARF.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the 6th leading cause of cancer worldwide. Its recurrence ranges from 6% to 26%. In the literature, many factors are associated with higher risk of recurrence, without a clear definition of the best method that could predict this highly lethal event. OBJECTIVE The aim of this study was to evaluate the immunoexpression of immunohistochemical markers: HSP70, glypican 3, glutamine synthetase, and beta-catenin, as well as studying their association with tumor characteristics and prognosis of patients undergoing liver transplantation for HCC. METHODS We studied 90 patients who underwent liver transplantation from 1998 to 2012. Afterwards we evaluated factors related to survival, tumor recurrence, and the correlation of expression of the immunohistochemical markers. RESULTS Immunohistochemical marker glutamine synthetase showed a positive trend toward better survival. HSP70-positive patients had a higher prevalence of histologic grade III. Patients with positive glypican 3 showed larger lesions and a higher number with AFP >200 ng/mL. Patients with positive beta-catenin showed larger nodules and more with histologic grade III. The association between beta-catenin and glypican 3 showed positive association with larger nodules. CONCLUSIONS Most of the markers studied had a correlation with at least one of the variables studied, confirming our hypothesis that these markers can indeed assist in assessing the prognosis of patients undergoing liver transplantation for HCC.

Abstract
The aim of this study was to determine risk factors for adverse events (AE)-related treatment discontinuation and severe anemia among patients with chronic hepatitis C virus (HCV) genotype 1 infection, treated with first-generation protease inhibitor (PI)-based therapy. We included all patients who initiated treatment with PI-based therapy at a Brazilian university hospital between November 2013 and December 2014. We prospectively collected data from medical records using standardized questionnaires and used Epi Info 6.0 for analysis. Severe anemia was defined as hemoglobin ≤8.5 mg/dL. We included 203 patients: 132 treated with telaprevir (TVR) and 71 treated with boceprevir (BOC). AE-related treatment discontinuation rate was 19.2% and anemia was the main reason (38.5%). Risk factors for treatment discontinuation were higher comorbidity index (OR=1.85, CI=1.05-3.25) for BOC, and higher bilirubin count (OR=1.02, CI=1.01-1.04) and lower BMI (OR=0.98, CI=0.96-0.99) for TVR. Severe anemia occurred in 35 (17.2%) patients. Risk factors for this outcome were lower estimated glomerular filtration rate (eGFR; OR=0.95, CI=0.91-0.98) for patients treated with TVR, and higher comorbidity index (OR=2.21, CI=1.04-4.67) and ribavirin dosage (OR=0.84, CI=0.72-0.99) for those treated with BOC. Fifty-five (57.3%) patients treated with TVR and 15 (27.3%) patients treated with BOC achieved sustained virological response (SVR). Among patients who received TVR and interrupted treatment due to AE (n=19), only 26.3% (n=5) achieved SVR (P=0.003). Higher number of comorbidities, lower eGFR and advanced liver disease are associated with severe anemia and early treatment cessation, which may compromise SVR achievement.

Abstract
Recurrent hepatitis C after orthotopic liver transplantation (OLT) is universal and
can lead to graft failure and, consequently, reduced survival. Hepatitis C treatment
can be used to prevent these detrimental outcomes. The aim of this study was to
describe rates of hepatitis C recurrence and sustained virological response (SVR) to
interferon-based treatment after OLT and its relationship to survival and progression
of liver disease through retrospective analysis of medical records of 127 patients
who underwent OLT due to cirrhosis or hepatocellular carcinoma secondary to chronic
hepatitis C between January 2002 and December 2013. Fifty-six patients were diagnosed
with recurrent disease, 42 started interferon-based therapy and 37 completed
treatment. Demographic, treatment- and outcome-related variables were compared
between SVR and non-responders (non-SVR). There was an overall 54.1% SVR rate with
interferon-based therapies. SVR was associated with longer follow-up after treatment
(median 66.5 vs 37 months for non-SVR, P=0.03) and after OLT (median
105 vs 72 months, P=0.074), and lower rates of disease progression
(15 vs 64.7%, P=0.0028) and death (5 vs 35.3%,
P=0.033). Regardless of the result of therapy (SVR or non-SVR), there was a
significant difference between treated and untreated patients regarding the
occurrence of death (P<0.001) and months of survival (P<0.001). Even with
suboptimal interferon-based therapies (compared to the new direct-acting antivirals)
there is a 54.1% SVR rate to treatment. SVR is associated with improved survival and
reduced risks of clinical decompensation, loss of the liver graft and death.

Abstract
Hepatitis C virus (HCV) genotype 3 is responsible for 30.1% of chronic hepatitis C infection cases worldwide. In the era of direct-acting antivirals, these patients have become one of the most challenging to treat, due to fewer effective drug options, higher risk of developing cirrhosis and hepatocellular carcinoma and lower sustained virological response (SVR) rates. Currently there are 4 recommended drugs for the treatment of HCV genotype 3: pegylated interferon (PegIFN), sofosbuvir (SOF), daclatasvir (DCV) and ribavirin (RBV). Treatment with PegIFN, SOF and RBV for 12 weeks has an overall SVR rate of 83–100%, without significant differences among cirrhotic and non-cirrhotic patients. However, this therapeutic regimen has several contraindications and can cause significant adverse events, which can reduce adherence and impair SVR rates. SOF plus RBV for 24 weeks is another treatment option, with SVR rates of 82–96% among patients without cirrhosis and 62–92% among those with cirrhosis. Finally, SOF plus DCV provides 94–97% SVR rates in non-cirrhotic patients, but 59–69% in those with cirrhosis. The addition of RBV to the regimen of SOF plus DCV increases the SVR rates in cirrhotic patients above 80%, and extending treatment to 24 weeks raises SVR to 90%. The ideal duration of therapy is still under investigation. For cirrhotic patients, the optimal duration, or even the best regimen, is still uncertain. Further studies are necessary to clarify the best regimen to treat HCV genotype 3 infection.

Abstract
Although long regarded as the gold standard for liver fibrosis staging in chronic hepatitis C (CHC), liver biopsy (LB) implies both the risk of an invasive procedure and significant variability. The aim of this study was to evaluate the diagnostic performance for transient elastography (TE) and aspartate aminotransferase to platelet index (APRI) used alone and in combination compared to liver biopsy and to analyze false positive/negative results. Patients with CHC, and no previous clinical diagnosis of cirrhosis were enrolled to undergo liver biopsy, TE and APRI. A total of 182 adult patients with a median age of 55 years and median body mass index of 26.71 kg/m2 were analyzed. On LB, 56% of patients had significant levels of fibrosis (METAVIR F≥2) and 28% had advanced fibrosis (F3/F4). The strongest performance for both tests was observed for exclusion of advanced fibrosis with good negative predictive values (89 and 86%, respectively). Low necroinflammatory activity on LB was associated with false negative TE. False positives were associated with NASH and smaller LB fragments. Correlation between APRI and Fibroscan for F≥2 was 100% and 84% for F≥3 and remained high in both false negative and false positive instances, correctly identifying F<2 in 71% of cases and F<3 in 78% (and potentially foregoing up to 84% of LB). We concluded that low individual performance indicators could be attributable to limitations of LB. Poorer differentiation of lower levels of fibrosis is a known issue for LB and remains so for noninvasive tests. Good predictability is possible, however, for advanced fibrosis.

Abstract
INTRODUCTION Muscular weakness in combination with malnutrition can induce a global motor impairment and physical inactivity, adversely impairing the daily living activities and quality of life of end-stage liver disease patients who are candidates for liver transplantation. OBJECTIVES To evaluate functional status, pulmonary capacity, body composition and quality of life in end-stage liver disease patients who are candidates for liver transplantation; to verify if there is a correlation between the functional variables of the individuals tested through the 6-minute walk test (6MWT) and covariables: pulmonary function test (PFP), quality of life and body composition. METHODS This study was carried out at the Liver Transplantation Unit of the State University of Campinas (UNICAMP). We included 46 patients with end-stage liver disease who underwent the following evaluations: medical history, quality of life questionnaire "Short Form 36" (SF-36), surface electromyography (sEMG) of the diaphragm and rectus abdominis muscles, body composition assessment by electrical vioimpedance (BIA), 6MWT and PFP. RESULTS Univariate analysis and Pearson's correlation found correlations between distance walked on 6MWT and QOL (P = .006 and P = .02) and TBW (P = .5 and P = .02). Pearson's correlation were found between respiratory variables of 6MWT, QOL, and PFP. CONCLUSION The functional status may be correlated to body composition, quality of life and pulmonary capacity of patients with liver disease, candidates for transplantation.

Abstract
BACKGROUND Candidates for liver transplantation may have malnutrition, fatigue, loss of muscle mass and function. The combination of these factors leads to overall physical disability and physical inactivity. OBJECTIVE The aim of the study was to evaluate the effects of a respiratory physiotherapeutic program on liver transplantation candidates. METHOD Forty-two patients were evaluated by respiratory muscle strength, surface electromyography of the rectus abdominis and diaphragm, and spirometry. We also applied the SF-36. The patients were divided into two groups: 12 randomly assigned to the control group and 5 in the intervention group. The intervention consisted of an explanatory and illustrative manual to be followed at home with diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT, lifting the upper limbs with a bat, and strengthening the abdominals. RESULTS Significant difference was found between initial forced expiratory flow (FEF)25-75% (P = .042) and final FEF25-75 in the intervention group. The control group had significant difference (P = .036) in the diaphragm RMS between initial time and end time. In conclusion, the control group showed greater electrical activity of the diaphragm after 3 months. CONCLUSION The intervention group benefited from the exercise, thus improving the FEF25-75%.

Abstract
BACKGROUND Rhabdomyolysis is a syndrome characterized by impaired metabolic integrity of myocytes, causing the release of intracellular constituents into the circulation, and can be a serious side effect of drug intake. CASE REPORT This report describes a unique case of rabdomyolysis secondary in which ciprofibrate, sirolimus, cyclosporine, and pegylated interferon-α in a liver transplant patient was used. A 47-year-old male liver transplant recipient in 2009, who had hepatitis C and incidental hepatocellular carcinoma, underwent immunosuppressive therapy (cyclosporine and sirolimus). The patient is currently in treatment for viral recurrence with pegylated interferon-α and ribavirin; he had a history of hypertriglyceridemia treated with ciprofibrate. He had development of severe and generalized myalgia and fever after the eighth application of pegylated interferon-α and increasing doses of cyclosporine. Laboratorial tests showed acute renal failure and significant increase in creatine kinase. Rhabdomyolysis secondary to interaction of fibrate-cyclosporine-pegylated interferon-α was postulated. CONCLUSIONS Medical professionals should be aware of possible drug interactions and should monitor patients receiving these drugs.

Abstract
INTRODUCTION Co-infected HIV and hepatitis subjects are candidates for a liver transplantation because of progressive liver disease. Chronic liver disease, co-infected or not, requires assessment of respiratory function before liver transplantation. The respiratory evaluation of these 2 groups compared with healthy individuals can define deficits, and this can impair a full recovery after transplant surgery. OBJECTIVE This study sought to compare the respiratory profile in co-infected patients with chronic liver disease who are candidates for liver transplantation with that of healthy subjects. METHODS Through respiratory evaluation of flows and lung volumes (spirometry), muscle activity (surface electromyography), and maximum pressure (manovacuometer), 250 people were distributed into 3 groups: 14 patients with HIV and liver disease, 65 healthy subjects, and 171 patients with chronic liver disease. The mean age (years) was respectively 47.5 ± 6.2, 48.3 ± 14.1, and 52.9 ± 8.5. The average body mass index (kg/m(2)) of the groups was 24.6 ± 4.5, 26.0 ± 3.2, and 28.5 ± 5.3, respectively. RESULTS There was a statistical difference among the groups in the root means square (RMS) rectus abdominis (μV) (P = .0016), RMS diaphragm (μV) (P = .0001), maximal inspiratory pressure (cmH2O) (P = .001), forced exhaled volume at the end of first second (%) (P = .002), and maximal mid expiratory flow 25% to 75% (%) (P = .0001) for the Kruskal-Wallis test. The multivariate analysis among the groups showed that the RMS diaphragm had a tendency to discriminate the co-infected subjects. CONCLUSIONS The co-infected HIV group showed a muscle deficit of diaphragm and rectus abdominis activity, and the liver disease group showed lower indexes in volumes and respiratory flows.

Abstract
BACKGROUND This article reports a case of hepar lobatum, a peculiar and rare type of liver deformity, originally described in association with infectious or parasitic diseases and with malignancies. CASE REPORT We have described a 42-year-old woman with this disorder, which was unrelated to the known conditions and referred for liver transplantation for having clinical manifestations of cirrhosis, portal hypertension, and impaired hepatic function. CONCLUSIONS The observed histologic pattern suggests that hepar lobatum could be, in some patients, the effect of a primary process of hamartomatous origin involving the organ vascular supply.

Abstract
INTRODUCTION Liver transplantation has become the most effective therapy for the treatment of patients with end-stage liver disease. With new immunosuppressive agents the incidence of acute rejection has been significantly reduced, but infection has become a serious problem. OBJECTIVE Our objective was to correlate cytomegalovirus (CMV) positivity of antigenemia and polymerase chain reaction (PCR) with clinical manifestations and bacterial infections among patients undergoing liver transplantation. METHODS This prospective study included patients monitored for 6 months for early detection of CMV infection. Sample collections were performed at the time of surgery and weekly until the second month followed by fortnightly in the third month, and monthly in the fourth to sixth month. CMV infection was defined by positive antigenemia (>3 cells) or 2 positive PCR tests associated or not with clinical symptoms. The methodology for the diagnosis of bacterial infection was through biochemical tests and the automated VITEK/bioMérieux (identification and antibiogram) using samples of urine and blood cultures. Chi-square test was used for dicotomic variables with significant differences when P < .05. RESULTS Sixteen patients (32%) had CMV infections, including 13 (81%) with concomitant infections. Thirty-four patients (68%) did not have CMV infections and 8 of these (24%) had bacterial infection. There was a high correlation with bacterial infections among CMV-positive patients. CONCLUSION Bacterial infections after liver transplantation were associated with CMV infection.

Abstract
BACKGROUND Postoperative poor graft function is a serious complication that can lead to graft loss requiring retransplantation or even death. The postoperative complications of primary nonfunction (PNF), early graft dysfunction (EGD), bleeding due to coagulopathy, and hepatic artery thrombosis (HAT) can lead to graft loss requiring retransplantation or even death. We determined the causes of death after liver transplantation. METHODS This was an observational descriptive study on adult liver transplant recipients from September 1991 to December 2011. The cutoff for the definition of death was 30 days after surgery. We included patients older than 18 years of age who underwent liver grafts using the piggyback technique, excluding those who had retransplantations or liver-kidney transplantations. RESULTS We analyzed 561 liver transplantations through chart review. After application of exclusion criteria we had 81 patients for analysis. Overall mortality was classified into 3 main causes: PNF (34/81; 42%), EGD (10/81; 12%), and abdominal bleeding due to coagulopathy (9/81; 11%). CONCLUSION Despite advances, mortality in the first 30 days after surgery is still high, mainly related to the occurrence of PNF and EGD, whose causality was associated with red blood cell transfusion (>5 U).

Abstract
Hepatoportal sclerosis (HPS), first reported by Mikkelsen et al in 1965, is a pathologic condition that does not cause cirrhotic portal hypertension. The primary hepatic lesion in HPS is found in portal vein branches with preserved synthetic function. Rarely do patients with HPS need liver transplantation. The aim of this study was to describe the clinical and pathologic features of 6 HPS cases who underwent liver transplantation (OLT). From 2000 to 2008, 6 OLT candidates were diagnosed with HPS: 3 displayed bleeding varices and 4 ascites. Child-Pugh evaluation was class B (n = 4) or C (n = 2). The Model for End-stage Liver Disease scores were 18 (n = 2), 20 (n = 3), and 22 (n = 1). Cirrhosis resulted from presumed diagnoses of alcohol n = (1), autoimmune n = (2) or cryptogenic cirrhosis n = (3). On histologic examination, there was marked phlebosclerosis in all cases, including nonocclusive portal vein thrombosis (n = 3), intense portal fibrosis (n = 1), moderate portal fibrosis (n = 5), and uniform moderate sinusoidal dilatation without megasinusoid formation, but with ductal biliary proliferation and ductal biliary fibrosis in all cases. Cholestasis was observed in 1 and incomplete septal cirrhosis in 4 cases. None of the subjects showed histological features of the presumed underlying liver disease. The overall survival of this group was no different from that of other OLT patients. HPS causing hepatic failure may require liver transplantation. Fhlebosclerosis andportal fibrosis may contribute to the loss of hepatic synthesis leading to the need for hepatic transplant. Significant portal fibrosis and phlebosclerosis can contribute to hepatic parenchymal and posterior synthetic loss.

Abstract
INTRODUCTION Orthotopic liver transplantation (OLT) is a rational therapeutic option for early-stage hepatocellular carcinoma (HCC) providing a potential cure and improving survival. METHODS This retrospective study of a longitudinal cohort used an electronic database collected prospectively from September 1997 to May 2010. The variables were gender, age (years), and alpha-fetoprotein (AFP) level (ng/mL). In explanted livers we observed: microvascular or macrovascular invasion, number of nodules and their largest size, Edmondson-Steiner histological differentiation, incidental tumor transarterial chemoembolization (TACE), Milan criteria, and previous down-staging. RESULTS Five of 83 (6.0%) subjects including 68 (82%) males with a mean time to diagnosis of 9 months experienced tumor relapses. Mean patient age at HCC recurrence was 55.3 years for male and 44.6 years for female subjects. Vascular invasion was detected in 17/83 (20.5%) subjects, namely 2% of macrovascular invasion, and 52.5% with expanded Milan criteria due to an increased number and size of nodules in the explanted livers. An incidental tumor was observed in 29.5% of cases. Preoperative TACE treatment was performed in 13 (15.6%) patients. None of the patients who had a HCC recurrence had undergone TACE. AFP level at the time of recurrence was around 1,900 ng/mL. The predictive factor for mortality was nodule size (P=.04; hazard ratio=0.0269; confidence interval [CI], 95% 0.0094-0.299). CONCLUSION Patients with relapses showed the worst survival and tumor size was a predictive factor for recurrence.

Abstract
INTRODUCTION Influenza is a common cause of respiratory infection in transplant recipients. It is expected that A/H1N1 influenza virus causes more severe disease in solid-organ recipients. Our goal was to describe two A/H1N1 infections that occurred after Orthotopic liver transplantation followed by acute allograft rejection episodes. CASE REPORTS From March 2009 to March 2010 we observe two liver transplant patients with symptoms suggestive of A/H1N1 infection. The diagnosis was out based on a temperature of 37.8°C (100°F) or higher and the presence of a cough or using materials from anasopharyngeal and oropharyngeal swabs a sore throat. The diagnosis was confirmed by viral RNA detection by real-time reverse-transcriptase-polymerase-chain-reaction assay (RT-PCR) using materials from nasopharyngeal and oropharyngeal swabs. We performed the RT-PCR assay for A/H1N1 detection in a liver biopsy from one patient. Both patients were treated with usual doses of oseltamivir (75 mg twice daily for 5 days). One patient developed acute bacterial sinusitis requiring antibiotic therapy. Thereafter the liver enzymes increased and transplant biopsies showed moderate-to-severe acute cellular rejection. They were treated with corticosteroids. The liver enzymes normalized after 3 months. CONCLUSION A/H1N1 influenza can lead to a severe acute cellular rejection episode with corticosteroid resistant treatment in liver transplant patients. Transplant centers should be aware of a possible relationship between A/H1N1 infections and acute allograft rejection episodes.

Abstract
INTRODUCTION A liver transplantation is the first choice of treatment for patients with hepatic insufficiency due to chronic diseases. Infections in the postoperative period represent one of the main causes of mortality in these cases. However, few articles have evaluated the predominance of certain infectious diseases and their influence on postoperative mortality. METHODS We retrospectively evaluated the medical records of 236 patients who underwent liver transplantation from January 1997 to January 2007. In these records we checked the serological profiles for these diseases: toxoplasmosis, syphilis, human T lymphotropic virus (HTLV) I and II infection, Chagas disease, hepatitis A, hepatitis B, hepatitis C, paracoccidioidomycosis, tuberculosis, acquired immunodeficiency syndrome, cytomegalovirus (CMV), and mononucleosis (Epstein-Barr virus [EBV]). The statistical analysis was performed by table frequencies. RESULTS CMV showed positivity (CMV-IgG) in 94.7% of patients, 95.8% for EBV, 33.3% for toxoplasmosis, 47.9% for hepatitis C, and 5% for hepatitis B. CONCLUSION Our analysis showed the importance of serological investigations and diagnostic examinations before the transplantation procedure, seeking to minimize possible reactivation of the disease after the use of immunosuppression drugs, particularly in the first 6 months after transplantation, or even to avoid a primary infection.

Abstract
Obstruction of the portal vein may be related to constriction by malignant tumors or thrombosis associated with liver disease. We herein have reported our experience with patients undergoing liver transplantation with portal vein thrombosis (PVT) whose diagnosis was made intraoperatively. From September 1991 to May 2009, we studied 27/419 (6.4%) patients with PVT who were evaluated according to the presence of esophagogastric varices, underlying disease, malignancy, and if there was previous surgery, review of medical records on data collected prospectively. We observed 24 (88.9%) patients with PVT grade 1, 2 (7.4%) with grade 2, and 1 (3.7%) with grade 3. The average age of the PVT patients was 47.5 years; the average model for End-Stage Liver Discase score was 18.3, and the predominant diagnosis, hepatitis C cirrhosis. Eighteen underwent a sclerotherapy/ligature. The sensitivity of ultrasound for grade 1 thrombosis was 39.1%; for grade 2, 50%; and for grade 3, 100%. Portal vein thrombectomy was performed in 24 patients. In other patients (grade 2), we performed an anastomosis of the donor portal vein to the recipient gastric vein or to a greater splanchnic collateral vein. In only 1 patient was the graft performed using the donor portal vein-donor iliac vein-recipient superior mesenteric vein. None of the patients displayed PVT in the immediate postoperative period. Actuarial survivals at the years 1, 3, and 5 were 85%, 74%, and 63%, respectively. We concluded that PVT cannot be considered to be a contraindication for liver transplantation.

Abstract
INTRODUCTION Anxiety can be considered an emotional state that does not present itself at the same intensity in all patients, and can be classified into 3 levels: mild, moderate, and severe. The patient, upon entering the waiting list for transplantation, reflects on the decision taken, which leaves him constantly anxious about the idea of possible death. OBJECTIVE This study had the aim of evaluating the degree of anxiety observed in orthotopic liver transplantation (OLT) candidates and whether there was a correlation between anxiety and etiologic diagnosis. METHODS This study was a prospective study where the patients underwent psychological evaluation by Beck Anxiety Inventory (BAI). The anxiety level was minimal, mild, moderate, or severe. The Model for End-Stage Liver Disease (MELD) score and etiology were recorded. RESULTS The level of anxiety found were as follows: 55% minimal, 27% mild, 12% moderate, and 7% severe. The correlation between level of anxiety and etiologic diagnosis showed that 71% of patients with alcoholic cirrhosis and 60% of those with liver cancer showed a minimal degree of anxiety and 27% of patients with autoimmune cirrhosis had severe anxiety. CONCLUSION We found that in patients with autoimmune hepatitis, the degree of anxiety was more pronounced. It is believed that the absence of physical symptoms is an important factor when observing anxiety in OLT candidates.

Abstract
Enterococcus spp bacteremia is associated with high mortality and the appearance of high-level gentamicin resistance (HLGR) created additional challenges for the treatment of these infections. We evaluated the epidemiological and clinical characteristics of patients with bacteremias caused by HLGR and non_HLGR Enterococcus faecalis isolates at a teaching hospital in the State of São Paulo, Brazil. Patients with bacteremia due to E. faecalis diagnosed between January 1999 and December 2003 were included in the study. We collected clinical, epidemiological, and microbiological data from medical records. Banked isolates were typed using pulsed-field gel electrophoresis. We identified 145 cases of E. faecalis bacteremia: 66 (45.5%) were caused by HLGR isolates and 79 (54.5%) by non_HLGR. In the univariate analysis, patients with HLGR infection were older, had higher rates of bladder catheterization, and more often had treatment with cephalosporin, quinolone, and/or carbapenem compared with patients with non_HLGR infection (P < 0.05). Multivariate analysis indicated that older age, hematological malignancy, and previous use of vancomycin were independently associated with HLGR (P < 0.05). Mortality rates were not significantly different among patients with HLGR (50%) and non_HLGR (43%) infections (P = 0.40). Of the 32 genotyped isolates, 16 were distributed into 6 main electrophoresis patterns and 16 others had distinct patterns. E. faecalis bacteremia is associated with high mortality and is frequently caused by HLGR isolates at this teaching hospital. The variability among genotyped isolates suggests that endogenous infections, rather than patient-to-patient transmission of E. faecalis, are more common at this institution.

Abstract
We sought to evaluate our experience concerning the high waiting list mortality rate for orthotopic liver transplantation (OLT) using the MELD (Model for End-Stage Liver Disease), which has been shown to predict short-term survival better than Child-Turcotte-Pugh (CTP) classification. The predominant end-stage disease was cirrhosis due to hepatitis C virus (67%), patient mean age was 36.8 years, and 72.1% were men. When the patients were included on a waiting list, the MELD score was stratified into W: 0 to 10; X: 11 to 20, and Y: 21 to 40 and the CPT as A: 5 to 6, B: 7 to 9, and C: 10 to 15. It was also observed that 77.8% of patients were on the waiting list, 16.4% underwent OLT and 5.8% had been removed. The estimated survival rate after 1 year was W = 85.4%; X = 83.3%, Y = 46.8%; A = 81.3%, B = 84.2%, C = 45.9%. Child median score was 8 +/- 1.5 (5 to 15) and the MELD was 14.7 +/- 5.1 (8 to 43). The mortality rate was 20.2%. Severe patients classified as Y or C showed greater mortality than the other groups (P <.001), but no significant difference between Y and C strata. The mortality rate was the same as in previous years.
