Direct-acting antivirals are effective and safe in HCV/HIV-coinfected liver transplant recipients who experience recurrence of hepatitis C: A prospective nationwide cohort study.

Direct-acting antivirals have proved to be highly efficacious and safe in monoinfected liver transplant (LT) recipients who experience recurrence of hepatitis C virus (HCV) infection. However, there is a lack of data on effectiveness and tolerability of these regimens in HCV/HIV-coinfected patients who experience recurrence of HCV infection after LT. In this prospective, multicenter cohort study, the outcomes of 47 HCV/HIV-coinfected LT patients who received DAA therapy (with or without ribavirin [RBV]) were compared with those of a matched cohort of 148 HCV-monoinfected LT recipients who received similar treatment. Baseline characteristics were similar in both groups. HCV/HIV-coinfected patients had a median (IQR) CD4 T-cell count of 366 (256-467) cells/µL. HIV-RNA was <50 copies/mL in 96% of patients. The DAA regimens administered were SOF + LDV ± RBV (34%), SOF + SMV ± RBV (31%), SOF + DCV ± RBV (27%), SMV + DCV ± RBV (5%), and 3D (3%), with no differences between the groups. Treatment was well tolerated in both groups. Rates of SVR (negative serum HCV-RNA at 12 weeks after the end of treatment) were high and similar for coinfected and monoinfected patients (95% and 94%, respectively; P = .239). Albeit not significant, a trend toward lower SVR rates among patients with advanced fibrosis (P = .093) and genotype 4 (P = .088) was observed. In conclusion, interferon-free regimens with DAAs for post-LT recurrence of HCV infection in HIV-infected individuals were highly effective and well tolerated, with results comparable to those of HCV-monoinfected patients.

Midodrine and albumin for prevention of complications in patients with cirrhosis awaiting liver transplantation. A randomized placebo-controlled trial.

BACKGROUND & AIMS: Patients with decompensated cirrhosis on the waiting list for liver transplantation (LT) commonly develop complications that may preclude them from reaching LT. Circulatory dysfunction leading to effective arterial hypovolemia and activation of vasoconstrictor systems is a key factor in the pathophysiology of complications of cirrhosis. The aim of this study was to investigate whether treatment with midodrine, an alpha-adrenergic vasoconstrictor, together with intravenous albumin improves circulatory dysfunction and prevents complications of cirrhosis in patients awaiting LT. METHODS: A multicenter, randomized, double-blind, placebo-controlled trial (NCT00839358) was conducted, including 196 consecutive patients with cirrhosis and ascites awaiting LT. Patients were randomly assigned to receive midodrine (15-30 mg/day) and albumin (40 g/15 days) or matching placebos for one year, until LT or drop-off from inclusion on the waiting list. The primary endpoint was incidence of any complication (renal failure, hyponatremia, infections, hepatic encephalopathy or gastrointestinal bleeding). Secondary endpoints were mortality, activity of endogenous vasoconstrictor systems and plasma cytokine levels. RESULTS: There were no significant differences between both groups in the probability of developing complications of cirrhosis during follow-up (p = 0.402) or one-year mortality (p = 0.527). Treatment with midodrine and albumin was associated with a slight but significant decrease in plasma renin activity and aldosterone compared to placebo (renin -4.3 vs. 0.1 ng/ml.h, p < 0.001; aldosterone -38 vs. 6 ng/dl, p = 0.02, at week 48 vs. baseline). Plasma norepinephrine only decreased slightly at week 4. Neither arterial pressure nor plasma cytokine levels changed significantly. CONCLUSIONS: In patients with cirrhosis awaiting LT, treatment with midodrine and albumin, at the doses used in this study, slightly suppressed the activity of vasoconstrictor systems, but did not prevent complications of cirrhosis or improve survival. LAY SUMMARY: Patients with cirrhosis who are on the liver transplant waiting list often develop complications which prevent them from receiving a transplant. Circulatory dysfunction is a key factor behind a number of complications. This study was aimed at investigating whether treating patients with midodrine (a vasoconstrictor) and albumin would improve circulatory dysfunction and prevent complications. This combined treatment, at least at the doses administered in this study, did not prevent the complications of cirrhosis or improve the survival of these patients.

Clinical outcomes of patients undergoing antiviral therapy while awaiting liver transplantation.

BACKGROUND & AIMS: Antiviral therapy for the treatment of hepatitis C (HCV) infection has proved to be safe and efficacious in patients with cirrhosis awaiting liver transplantation (LT). However, the information regarding the clinical impact of viral eradication in patients on the waiting list is still limited. The aim of the study was to investigate the probability of delisting in patients who underwent antiviral therapy, and the clinical outcomes of these delisted patients. METHODS: Observational, multicenter and retrospective analysis was carried out on prospectively collected data from patients positive for HCV, treated with an interferon-free regimen, while awaiting LT in 18 hospitals in Spain. RESULTS: In total, 238 patients were enrolled in the study. The indication for LT was decompensated cirrhosis (with or without hepatocellular carcinoma [HCC]) in 171 (72%) patients, and HCC in 67 (28%) patients. Sustained virologic response (SVR) rate was significantly higher in patients with compensated cirrhosis and HCC (92% vs. 83% in patients with decompensated cirrhosis with or without HCC, p=0.042). Among 122 patients with decompensated cirrhosis without HCC, 29 (24%) were delisted due to improvement. No patient with baseline MELD score >20 was delisted. After delisting (median follow-up of 88weeks), three patients had clinical decompensations and three had de novo HCC. Only two of the patients with HCC had to be re-admitted onto the waiting list. The remaining 23 patients remained stable, with no indication for LT. CONCLUSIONS: Antiviral therapy is safe and efficacious in patients awaiting LT. A quarter of patients with decompensated cirrhosis can be delisted asa result of clinical improvement, which appears to be remain stable in most patients. Thus, delisting is a safe strategy that could spare organs and benefit other patients with a more urgent need. LAY SUMMARY: Antiviral therapy in patients awaiting liver transplantation is safe and efficacious. Viral eradication allows removal from the waiting list of a quarter of treated patients. Delisting because of clinical improvement is a safe strategy that can spare organs for patients in urgent need.

[Evaluation and treatment of the critically ill cirrhotic patient]. / Evaluación y tratamiento del paciente cirrótico crítico.

Cirrhotic patients often develop severe complications requiring ICU admission. Grade III-IV hepatic encephalopathy, septic shock, acute-on-chronic liver failure and variceal bleeding are clinical decompensations that need a specific therapeutic approach in cirrhosis. The increased effectiveness of the treatments currently used in this setting and the spread of liver transplantation programs have substantially improved the prognosis of critically ill cirrhotic patients, which has facilitated their admission to critical care units. However, gastroenterologists and intensivists have limited knowledge of the pathogenesis, diagnosis and treatment of these complications and of the prognostic evaluation of critically ill cirrhotic patients. Cirrhotic patients present alterations in systemic and splanchnic hemodynamics, coagulation and immune dysfunction what further increase the complexity of the treatment, the risk of developing new complications and mortality in comparison with the general population. These differential characteristics have important diagnostic and therapeutic implications that must be known by general intensivists. In this context, the Catalan Society of Gastroenterology and Hepatology requested a group of experts to draft a position paper on the assessment and treatment of critically ill cirrhotic patients. This article describes the recommendations agreed upon at the consensus meetings and their main conclusions.

Pegylated interferon plus ribavirin in HIV-infected patients with recurrent hepatitis C after liver transplantation: a prospective cohort study.

BACKGROUND & AIMS: The aim of this study was to evaluate the results of treatment with pegylated interferon and ribavirin for the recurrence of hepatitis C after liver transplantation in HCV/HIV-coinfected patients. METHODS: This was a prospective, multicentre cohort study, including 78 HCV/HIV-coinfected liver transplant patients who received treatment for recurrent hepatitis C. For comparison, we included 176 matched HCV-monoinfected patients who underwent liver transplantation during the same period of time at the same centres and were treated for recurrent hepatitis C. RESULTS: Antiviral therapy was discontinued prematurely in 56% and 39% (p = 0.016), mainly because of toxicity (22% and 11%, respectively; p=0.034). Sustained virological response (SVR) was achieved in 21% of the coinfected patients and in 36% of monoinfected patients (p = 0.013). For genotype 1, SVR rates were 10% and 33% (p = 0.002), respectively; no significant differences were observed for the other genotypes. A multivariate analysis based on the whole series identified HIV-coinfection as an independent predictor of lack of SVR (OR, 0.17; 95% CI, 0.06-0.42). Other predictors of SVR were donor age, pretreatment HCV viral load, HCV genotype, and early virological response. SVR was associated with a significant improvement in survival: 5-year survival after antiviral treatment was 79% for HCV/HIV-coinfected patients with SVR vs. 43% for those without (p = 0.02) and 92% vs. 60% in HCV-monoinfected patients (p < 0.001), respectively. CONCLUSIONS: The response to pegylated interferon and ribavirin was poorer in HCV/HIV-coinfected liver recipients, particularly those with genotype 1. However, when SVR was achieved, survival of coinfected patients increased significantly.

Improvement of quality of care provided to outpatients with hepatic cirrhosis after an educational intervention.

OBJECTIVE: A set of indicators has been reported to measure the quality of care for cirrhotic patients, and previously published studies report variable adherence rates to these indicators. This study aimed to assess the quality of care provided to cirrhotic outpatients before and after an educational intervention by determining its impact on adherence to quality indicators. METHODS: We conducted a quasi-experimental, cross-sectional study including 324 cirrhotic patients seen in 2017 and 2019 at a tertiary teaching hospital in Spain. Quality indicators were assessed in five domains: documentation of cirrhosis etiology, disease severity assessment, hepatocellular carcinoma (HCC) screening, variceal bleeding prophylaxis, and vaccination. After identifying areas for improvement, an educational intervention was implemented. A second evaluation was performed after the intervention to assess changes in adherence rates. RESULTS: Before the intervention, adherence rates were excellent (>90%) for indicators related to variceal bleeding prophylaxis and documentation of cirrhosis etiology, acceptable (60-80%) for HCC screening and disease severity assessment, and poor (<50%) for vaccinations. After the educational intervention, there was a statistically significant improvement in adherence rates for eight indicators related to HCC screening (70-90%), disease severity assessment (90%), variceal bleeding prophylaxis (>90%), and vaccinations (60-90%). CONCLUSION: Our study demonstrates a significant improvement in the quality of care provided to cirrhotic outpatients after an educational intervention. The findings highlight the importance of targeted educational interventions to enhance adherence to quality indicators in the management of cirrhosis.

Polymorphonuclear counts in ascitic fluid and microorganisms producing spontaneous bacterial peritonitis: an under-recognized relationship.

BACKGROUND AND AIMS. In cirrhotic patients with spontaneous bacterial peritonitis (SBP) higher polymorphonuclear (PMN) count in ascitic fluid have been reported in infections caused by Gram-negative bacilli (GNB) as opposed to Gram-positive cocci (GPC). However, the influence of other associated factors on the PMN count, such as the specific microorganism causing the episode of SBP, has not been well established. METHODS. Retrospective observational study of 194 episodes of positive ascitic and/or blood culture SBP in 159 patients with liver cirrhosis (2001-2009). Parameters associated with PMN count in ascitic fluid at diagnosis were evaluated. RESULTS. The multivariate analysis (model 1) showed that a virulent etiology of the infection [coefficient 3.941 (95% confidence interval (95 CI): 0.421-7.461)] and the model for end-stage liver disease (MELD) score [coefficient 0.196 (95 CI: 0.007-0.384)] were positively associated with the PMN count in ascites, while a nosocomial acquisition was inversely associated [coefficient -3.546 (95 CI: -6.855 - -0.238)]. A nonsignificant trend toward higher PMN count was found in GNB versus GPC, but there were differences between groups of microorganisms: pyogenic streptococci [median (p25-p75): 3211 (1615-8004)], Enterobacteriaceae [2958 (917-7690)], Vibrionaceae [9215 (375-17280)], nonfermenting GNB [1384 (565-3865)], viridans group streptococci [1044 (503-2354)] and enterococci [1050 (476-4655)](p = 0.005). No clear cut-offs of ascitic PMN count predicting a particular etiology could be calculated out of these data. CONCLUSIONS. In cirrhotic patients with SBP, the causing microorganism, the place of acquisition of the infection and the host liver condition were the main factors determining PMN count in ascitic fluid. Third-generation cephalosporin resistance was associated with low PMN count probably because this group included bacteria with inherent low virulence.

Risk factors for resistance to ceftriaxone and its impact on mortality in community, healthcare and nosocomial spontaneous bacterial peritonitis.

BACKGROUND & AIMS: The recent emergence of third-generation cephalosporin resistance in spontaneous bacterial peritonitis is of great concern, although neither the risk factors for resistance nor its real impact on mortality have been well defined. METHODS: We conducted a retrospective study of all spontaneous bacterial peritonitis episodes with positive blood and/or ascitic culture at our center (2001-2009). Episodes were classified according to the place of acquisition: community, healthcare system, or nosocomial. RESULTS: Two hundred and forty-six episodes were analyzed in 200 patients (150 males, 57.3 years): 34.6% community-acquired, 38.6% healthcare system-acquired, and 26.8% nosocomially-acquired. Third-generation cephalosporin resistance occurred in 21.5% (7.1% community-acquired, 21.1% healthcare system-acquired, 40.9% nosocomially-acquired). These resistant cases were categorized as extended-spectrum ß-lactamase-producing Gram-negative bacilli, other resistant Gram-negative bacilli, and Enterococci. Risk factors for resistance were previous use of cephalosporins, diabetes mellitus, upper gastrointestinal bleeding, nosocomial acquisition, and a low polymorphonuclear count in ascites. Regarding third-generation cephalosporin resistance, adequate empirical treatment was 80.7%. Independent predictors of mortality were nosocomial acquisition, poor hepato-renal function, immunosuppressive therapy, a marked inflammatory response during the episode and either third-generation cephalosporin-resistance or low rates of adequate empirical treatment. CONCLUSIONS: The risk of third-generation cephalosporin resistance was particularly high in nosocomially-acquired episodes of spontaneous bacterial peritonitis, but also occurred in healthcare system-acquired cases. The extent of resistance and the adequacy of empirical antibiotics had a significant effect on mortality along with the patient's hepato-renal function. These data can help determine the most suitable empirical antimicrobial treatments in these patients.

Paracetamol in therapeutic dosages and acute liver injury: causality assessment in a prospective case series.

BACKGROUND: Acute liver injury (ALI) induced by paracetamol overdose is a well known cause of emergency hospital admission and death. However, there is debate regarding the risk of ALI after therapeutic dosages of the drug.The aim is to describe the characteristics of patients admitted to hospital with jaundice who had previous exposure to therapeutic doses of paracetamol. An assessment of the causality role of paracetamol was performed in each case. METHODS: Based on the evaluation of prospectively gathered cases of ALI with detailed clinical information, thirty-two cases of ALI in non-alcoholic patients exposed to therapeutic doses of paracetamol were identified. Two authors assessed all drug exposures by using the CIOMS/RUCAM scale. Each case was classified into one of five categories based on the causality score for paracetamol. RESULTS: In four cases the role of paracetamol was judged to be unrelated, in two unlikely, and these were excluded from evaluation. In seven of the remaining 26 cases, the RUCAM score associated with paracetamol was higher than that associated with other concomitant medications. The estimated incidence of ALI related to the use of paracetamol in therapeutic dosages was 0.4 per million inhabitants older than 15 years of age and per year (99%CI, 0.2-0.8) and of 10 per million paracetamol users-year (95% CI 4.3-19.4). CONCLUSIONS: Our results indicate that paracetamol in therapeutic dosages may be considered in the causality assessment in non-alcoholic patients with liver injury, even if the estimated incidence of ALI related to paracetamol appears to be low.

Secondary bacterial peritonitis in cirrhosis: a retrospective study of clinical and analytical characteristics, diagnosis and management.

BACKGROUND & AIMS: Secondary bacterial peritonitis in cirrhotic patients is an uncommon entity that has been little reported. Our aim is to analyse the frequency, clinical characteristics, treatment and prognosis of patients with secondary peritonitis in comparison to those of patients with spontaneous bacterial peritonitis (SBP). METHODS: Retrospective analysis of 24 cirrhotic patients with secondary peritonitis compared with 106 SBP episodes. RESULTS: Secondary peritonitis represented 4.5% of all peritonitis in cirrhotic patients. Patients with secondary peritonitis showed a significantly more severe local inflammatory response than patients with SBP. Considering diagnosis of secondary peritonitis, the sensitivity of Runyon's criteria was 66.6% and specificity 89.7%, Runyon's criteria and/or polymicrobial ascitic fluid culture were present in 95.6%, and abdominal computed tomography was diagnostic in 85% of patients in whom diagnosis was confirmed by surgery or autopsy. Mortality during hospitalization was higher in patients with secondary peritonitis than in those with SBP (16/24, 66.6% vs. 28/106, 26.4%) (p<0.001). There was a trend to lower mortality in secondary peritonitis patients who underwent surgery (7/13, 53.8%) than in those who received medical treatment only (9/11, 81.8%) (p=0.21). Considering surgically treated patients, the time between diagnostic paracentesis and surgery was shorter in survivors than in non-survivors (3.2+/-2.4 vs. 7.2+/-6.1 days, p=0.31). CONCLUSIONS: Secondary peritonitis is an infrequent complication in cirrhotic patients but mortality is high. A low threshold of suspicion on the basis of Runyon's criteria and microbiological data, together with an aggressive approach that includes prompt abdominal computed tomography and early surgical evaluation, could improve prognosis in these patients.

Risk of transmission of systemic transthyretin amyloidosis after domino liver transplantation.

Recent reports of the transmission of systemic transthyretin (TTR) amyloidosis after domino liver transplantation (DLT) using grafts from patients with familial amyloid polyneuropathy (FAP) have raised concerns about the procedure. The aim of this study was to evaluate the transmission incidence of systemic TTR amyloidosis after DLT with a complete clinical, neurological, and pathological assessment. At our institution, DLT has been performed 31 times with livers from patients with FAP. Seventeen of the 19 patients still alive in 2008 agreed to enter the study. This cross-sectional study of this cohort of patients included clinical assessments, rectal biopsy, and electroneuromyography (as well as sural nerve biopsy when it was indicated). The mean follow-up at the time of the study was 62.6 ± 2.9 months. Clinically, 3 patients complained of weak dysesthesia. When a focused study was performed, 8 patients reported some kind of neurological and/or gastrointestinal disturbance. Six of the rectal biopsy samples showed amyloid deposits (TTR-positive). Electromyography (EMG) showed signs of mild sensorimotor neuropathy in 3 cases and moderate to severe sensorimotor neuropathy in 1 case. Only 2 of the 4 patients with EMG signs of polyneuropathy showed amyloid deposits in their rectal biopsy samples. Sural nerve biopsy revealed amyloid deposits (TTR-positive) in all 4 patients with EMG signs of polyneuropathy. Two patients with normal EMG findings had TTR-positive amyloid deposits in their sural nerve biopsy samples. In conclusion, de novo systemic amyloidosis after DLT may be more frequent and appear earlier than was initially thought. In our opinion, however, the graft shortage still justifies DLT in selected patients, despite the risk of de novo systemic amyloidosis. Sural nerve biopsy with EMG and clinical correlation is mandatory for confirming the disease. Indeed, other causes of neuropathy should be excluded.

Ulcer bleeding after band ligation of esophageal varices: Risk factors and prognosis.

BACKGROUND: Post-banding ulcer bleeding is a rare complication of endoscopic band ligation of esophageal varices with high morbidity and mortality. There exist no management guidelines for this complication. AIMS: To determine the incidence, outcome and risk factors of post-banding ulcer bleeding. METHODS: Data for cirrhotic patients with acute variceal bleeding during a six-year period were prospectively collected, and all band ligation sessions performed were retrospectively analyzed. Demographic, analytic and endoscopic data were recorded, as well as complications, outcome and management of each episode of post-banding ulcer bleeding. RESULTS: The study includes 521 band ligation sessions performed on 175 patients. There were 24 cases of post-banding ulcer bleeding in 21 patients (incidence 4.6%). Independent risk factors for post-banding ulcer bleeding were MELD score, hepatocellular carcinoma and total beta-blocker dose. Mortality during the bleeding episode was 23.8%. Active bleeding or adherent clots at the time of endoscopy was associated with treatment failure or death. CONCLUSIONS: Post-banding ulcer bleeding is an uncommon but severe complication of esophageal banding. Patients with hepatocellular carcinoma, poor liver function and a low beta-blocker dose have higher risk of post-banding ulcer bleeding. An aggressive treatment should be considered in case of active bleeding at endoscopy.

Deep-sequencing reveals broad subtype-specific HCV resistance mutations associated with treatment failure.

A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) α-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of "extra-target" RAS suggests the need for RAS screening in all three DAA target regions.

Clinically relevant differences in the model for end-stage liver disease and model for end-stage liver disease-sodium scores determined at three university-based laboratories of the same area.

The Model for End-Stage Liver Disease (MELD) score is considered an objective and reliable measure of liver disease severity. However, the use of specific laboratory methodologies may introduce significant and clinically relevant variations into the score. It has been suggested that the incorporation of sodium into MELD (MELD-Na) can provide a more accurate survival prediction than MELD alone. Before implementing organ allocation based on the MELD score in an area with 3 transplant centers, we studied whether there were significant variations in MELD and MELD-Na scores determined at each center. Seventy patients on the waiting list were studied simultaneously. Blood samples for each patient were divided into 3 aliquots and were processed in the 3 laboratories in order to calculate MELD and MELD-Na scores. There were statistical differences between the 3 laboratories in the MELD and MELD-Na scores and their parameters. The MELD score was identical in the 3 laboratories for only 6 of the 70 patients, and the MELD-Na score was identical for only 9. MELD and MELD-Na scores from 2 laboratories differed by 1 point or more in 54% and 47% of cases, respectively. Our study confirms that there is major variability in the MELD score, serum sodium, and MELD-Na score. These differences are clinically relevant, and in order to guarantee equitable organ allocation based on the MELD score, similar laboratory methodologies should be implemented at all centers in the same organ procurement area. Alternatively, the possibility of setting up a central laboratory in each organ procurement area should be considered.

Efficacy and Safety of Delayed Prolonged-Release Tacrolimus Initiation in De Novo Hepatitis C Virus-Negative Orthotopic Liver Transplant Recipients: A Single-Center, Single-Arm, Prospective Study.

BACKGROUND Delaying initiation of tacrolimus after liver transplantation (LT) is a potential renal-sparing strategy. We assessed safety and efficacy of delayed initiation of prolonged-release tacrolimus (PR-T) in de novo LT. MATERIAL AND METHODS This was a single-center, single-arm, prospective, 12-month observational study of hepatitis C virus-negative orthotopic LT patients. Immunosuppression included PR-T (initially 0.1 or 0.2 mg/kg/day) initiated on Day 3 post LT, basiliximab (20 mg) on post-transplantation Day 0 and Day 4, and intraoperative corticosteroids (500 mg). Patients received maintenance corticosteroids and mycophenolate mofetil (MMF) according to center protocol. MMF dose was adjusted according to thrombocyte count. The primary endpoint was the estimated glomerular filtration rate (eGFR) measured using the Modification of Diet in Renal Disease 4-variable formula at 12 months. Secondary endpoints included biopsy-confirmed acute rejection (BCAR) and dialysis requirement. Adverse events were recorded. RESULTS Sixty-nine patients (mean age 55.0 years) were included. Most patients started MMF on Day 1 (60.9%) or Day 2 (10.1%), and PR-T on Day 3 (55.1%) or Day 4 (29.0%). Mean tacrolimus trough levels (ng/mL) were: Day 7, 9.5±6.3; Day 10, 9.4±5.4; Month 1, 8.0±3.1; Month 3, 7.8±3.7; Month 6, 8.0±4.1; and Month 12, 7.2±3.1. Mean 12-month eGFR was 77.2±24.5 mL/min/1.73 m2; 72.5% of patients had eGFR >60 mL/min/1.73 m² at 12 months; 89.9% had no eGFR measurements <40 mL/min/1.73 m² during the study. Renal insufficiency (any eGFR <60 mL/min/1.73 m²) was diagnosed in 27.5% of patients; one patient required dialysis. There were no BCAR episodes; the infection rate was 36.2%, and 3 patients died. Overall, 19 patients (27.5%) developed de novo diabetes mellitus, 18 patients (26.1%) had hypercholesterolemia, and 12 patients (17.4%) had hypertriglyceridemia. CONCLUSIONS Quadruple therapy with delayed administration of PR-T was well tolerated and efficacious, and was associated with acceptable renal function over 12 months.

Impact of immunosuppression without steroids on rejection and hepatitis C virus evolution after liver transplantation: results of a prospective randomized study.

The purpose of this study was to evaluate the influence of a steroid-free immunosuppression on hepatitis C virus (HCV) recurrence. A total of 198 liver transplantation (LT) patients were randomized to receive immunosuppression with basiliximab and cyclosporine, either with prednisone (steroid [St] group) or without prednisone (no steroids [NoSt] group). The group of 89 HCV-infected patients was followed up with protocol biopsies for 2 years after LT. This group of HCV patients are the patients evaluated in the present study. The rejection rate was 19% (St: 21% versus NoSt: 17%; P = 0.67). Patients in the St group had a slightly higher rate of bacterial infections (59% versus 38%; P = 0.05). Almost all patients had histological HCV-recurrence (St: 39/40 (97%) versus NoSt: 40/41 (97%); P = 1). The percentage of accumulated biopsies with grade 4 portal inflammation at 6 months, 1 year, and 2 years were, 23%, 49%, and 49% in the NoSt group, compared to 33%, 55%, and 69% in the St group, respectively (P = 0.04 at 2 years). The percentage of accumulated biopsies with grade 3 or 4 fibrosis at 6 months, 1 year, and 2 years were 0%, 8%, and 22% in the NoSt group, compared to 8%, 19%, and 31% in the St group, respectively. Immunosuppression without steroids in HCV patients is safe, reduces bacterial infections and metabolic complications, and improves histological short-term evolution of HCV recurrence.

Spontaneous bacterial peritonitis and bacterascites prevalence in asymptomatic cirrhotic outpatients undergoing large-volume paracentesis.

BACKGROUND AND AIM: Spontaneous bacterial peritonitis and bacterascites prevalence in asymptomatic cirrhotic patients on large-volume paracentesis is unknown. The aim of this study was to investigate spontaneous bacterial peritonitis and bacterascites prevalence in a prospective cohort of cirrhotic outpatients following large-volume paracentesis with low risk of infection. METHODS: We prospectively studied all large-volume paracenteses performed in cirrhotic outpatients for 1 year. Patients with fever, abdominal pain, peritonism or hepatic encephalopathy were excluded from the study. The ascitic fluid was analyzed by means of a reagent strip with a colorimetric scale from 0 to 4. A strip test of 0 or 1 was considered negative. In those cases with a reagent strip > or =2, conventional polymorphonuclear count was performed. Ascitic fluid culture was done into blood culture bottles in all cases. RESULTS: We performed 204 paracenteses in 40 patients. Nine cases were excluded. Culture-negative neutrocytic ascites was diagnosed in one case (0.5%), while bacterascites was diagnosed in six out of 195 cases (3%), mainly by gram-positive cocci. CONCLUSION: The spontaneous bacterial peritonitis prevalence in outpatient cirrhotics with low risk of infection undergoing large-volume paracentesis is very low. Moreover, the prevalence of bacterascites is low and without clinical consequences. The routine analysis of ascitic fluid may be unnecessary in this clinical setting. Nevertheless, the use of reagent strips is a reasonable alternative due to its accessibility and low cost.

Serious drug-induced liver disease secondary to ezetimibe.

Ezetimibe is the first member of a new family of lipid-lowering drugs that inhibits uptake of dietary and biliary cholesterol. It was approved by the FDA in 2002 for hypercholesterolemia alone or in combination with statins. Its use has been spreading over the last years. Ezetimibe was considered a safe drug. We report a case of a woman who developed a serious hepatocellular drug-induced liver disease after 4 mo therapy with 10 mg daily of ezetimibe. After withdrawal of the drug, the patient recovered slowly. Ezetimibe may produce serious toxic hepatitis and prompt withdrawal is mandatory in case of a significant abnormality in liver testing after beginning or during treatment with ezetimibe.
