RESUMO

This multicenter study compares the outcomes of patients with cirrhosis undergoing liver transplantation (LT) or liver resection (LR) between January 2002 and July 2015 who had intrahepatic cholangiocarcinoma (iCCA) or combined hepatocellular-cholangiocarcinoma (cHCC-CCA) found incidentally in the native liver. A total of 49 (65%) LT and 26 (35%) LR patients with cirrhosis and histologically confirmed iCCA/cHCC-CCA ≤5 cm were retrospectively analyzed. LT patients had significantly lower tumor recurrence (18% versus 46%; P = 0.01), for which the median diameter of the largest nodule (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.02-1.12]; P = 0.006) and tumor differentiation (HR, 3.74; 95% CI 1.71-8.17; P = 0.001) were independently predictive. The LT group had significantly higher 5-year recurrence-free survival (RFS; 75% versus 36%; P = 0.004). In patients with tumors >2 cm but ≤5 cm, LT patients had a lower recurrence rate (21% versus 48%; P = 0.06) and a higher 5-year RFS (74% versus 40%; P = 0.06). Independent risk factors for recurrence were LT (protective; HR, 0.23; 95% CI, 0.07-0.82; P = 0.02), the median diameter of the largest nodule (HR, 1.10; 95% CI, 1.02-1.73; P = 0.007), and tumor differentiation (HR, 4.16; 95% CI, 1.37-12.66; P = 0.01). In the LT group, 5-year survival reached 69% and 65% (P = 0.40) in patients with tumors ≤2 cm and >2-5 cm, respectively, and survival was also comparable between iCCA and cHCC-CCA patients (P = 0.29). LT may offer a benefit for highly selected patients with cirrhosis and unresectable iCCA/cHCC-CCA having tumors ≤5 cm. Efforts should be made to evaluate tumor differentiation, and these results need to be confirmed prospectively in a larger population.

RESUMO

Transition describes a progressive and highly coordinated process encompassing the transfer of a young patient from paediatric care to the adult-care system. Transfer of medical care for an adolescent to adult services is a complex and challenging task requiring close collaboration of both the paediatric and adult-care providers. It must take into account the medical, psychosocial and educational needs of the young adult. The Transition Working Group of the French Network for Rare Liver Diseases (FILFOIE) proposes recommendations and tools designed to optimise the transition process of adolescents and young adults with chronic liver disease from child-based to adult-based healthcare services, focusing on three key time points: preparation before the transfer, the transfer process to the adult service, and finally reception and follow-up within the adult-care service.

RESUMO

BACKGROUND & AIMS: Immunotherapy for metastatic cancer can be complicated by the onset of hepatic immune-related adverse events (IRAEs). This study compared hepatic IRAEs associated with anti-programmed cell death protein 1 (PD-1)/PD ligand 1 (PD-L1) and anti-cytotoxic T lymphocyte antigen 4 (CTLA-4) monoclonal antibodies (mAbs). METHODS: Among 536 patients treated with anti-PD-1/PD-L1 or CTLA-4 immunotherapies, 19 (3.5%) were referred to the liver unit for grade ≥3 hepatitis. Of these patients, nine had received anti-PD-1/PD-L1 and seven had received anti-CTLA-4 mAbs, in monotherapy or in combination with anti-PD-1. Liver investigations were undertaken in these 16 patients, including viral assays, autoimmune tests and liver biopsy, histological review, and immunostaining of liver specimens. RESULTS: In the 16 patients included in this study, median age was 63 (range 33-84) years, and nine (56%) were female. Time between therapy initiation and hepatitis was five (range, 1-49) weeks and median number of immunotherapy injections was two (range, 1-36). No patients developed hepatic failure. Histology related to anti-CTLA-4 mAbs demonstrated granulomatous hepatitis including fibrin ring granulomas and central vein endotheliitis. Histology related to anti-PD-1/PD-L1 mAbs was characterised by lobular hepatitis. The management of hepatic IRAEs was tailored according to the severity of both the biology and histology of liver injury: six patients improved spontaneously; seven received oral corticosteroids at 0.5-1 mg/kg/day; two were maintained on 0.2 mg/kg/day corticosteroids; and one patient required pulses and 2.5 mg/kg/day of corticosteroids, and the addition of a second immunosuppressive drug. In three patients, immunotherapy was reintroduced without recurrence of liver dysfunction. CONCLUSIONS: Acute hepatitis resulting from immunotherapy for metastatic cancer is rare (3.5%) and, in most cases, not severe. Histological assessment can distinguish between anti-PD-1/PD-L1 and anti-CTLA-4 mAb toxicity. The severity of liver injury is helpful for tailoring patient management, which does not require systematic corticosteroid administration. LAY SUMMARY: Immunotherapy for metastatic cancer can be complicated by immune-related adverse events in the liver. In patients receiving immunotherapy for metastatic cancer who develop immune-mediated hepatitis, liver biopsy is helpful for the diagnosis and evaluation of the severity of liver injury. This study demonstrates the need for patient-oriented management, which could eventually avoid unnecessary systemic corticosteroid treatment.

RESUMO

BACKGROUND: A recurrence of hepatitis C virus (HCV) after liver transplantation affects survival in human immunodeficiency virus (HIV)/HCV coinfected patients. This study assessed the efficacy and safety of sofosbuvir (SOF)-based regimens in HIV/HCV coinfected patients after liver transplantation. METHODS: Twenty-nine HIV/HCV coinfected transplanted patients receiving tacrolimus-, cyclosporine-, or everolimus-based immunosuppressive therapy were enrolled in the Compassionate Use of Protease Inhibitors in Viral C Liver Transplantation cohort. Their antiviral treatment combined SOF, daclatasvir with or without ribavirin (n = 10/n = 6), or SOF, ledipasvir with or without ribavirin (n = 2/n = 11). RESULTS: The median delay between liver transplantation and treatment initiation was 37.5 months (interquartile range [IQR], 14.4-99.2). The breakdown of HCV genotypes was G1, 22 patients (75.9%); G3, 3 patients (10.3%); and G4, 4 patients (13.8%). The treatment indications were HCV recurrence (≥ F1 n = 23) or fibrosing cholestatic hepatitis (n = 6). Before starting SOF, the HCV viral load and CD4 count were 6.7 log10 IU/mL (IQR, 5.9-7.2) and 342 cells/mm (IQR, 172-483), respectively. At week 4, the HCV viral load was less than 15 IU/mL in 12 (42.9%) patients. The overall sustained virological response 12 was 96.6%. No significant drug-drug interactions were observed. CONCLUSIONS: SOF-based treatment regimens produced excellent results in HIV/HCV coinfected patients after liver transplantation, suggesting an important change in their prognosis.

RESUMO

BACKGROUND: Postoperative hepatic decompensation is a serious complication of liver resection in patients undergoing hepatectomy for hepatocellular carcinoma. Liver fibrosis and clinical significant portal hypertension are well-known risk factors for hepatic decompensation. Liver stiffness measurement is a noninvasive method of evaluating hepatic venous pressure gradient and functional hepatic reserve by estimating hepatic fibrosis. Effectiveness of liver stiffness measurement in predicting persistent postoperative hepatic decompensation has not been investigated. METHODS: Consecutive patients with resectable hepatocellular carcinoma were recruited prospectively and liver stiffness measurement of nontumoral liver was measured using FibroScan. Hepatic venous pressure gradient was measured intraoperatively by direct puncture of portal vein and inferior vena cava. Hepatic venous pressure gradient ≥10 mm Hg was defined as clinically significant portal hypertension. Primary outcome was persistent hepatic decompensation defined as the presence of at least one of the following: unresolved ascites, jaundice, and/or encephalopathy >3 months after hepatectomy. RESULTS: One hundred and six hepatectomies, including 22 right hepatectomy (20.8%), 3 central hepatectomy (2.8%), 12 left hepatectomy (11.3%), 11 bisegmentectomy (10.4%), 30 unisegmentectomy (28.3%), and 28 partial hepatectomy (26.4%) were performed in patients for hepatocellular carcinoma (84 men and 22 women with median age of 67.5 years; median model for end-stage liver disease score of 8). Ninety-day mortality was 4.7%. Nine patients (8.5%) developed postoperative hepatic decompensation. Multivariate logistic regression bootstrapped at 1,000 identified liver stiffness measurement (P = .001) as the only preoperative predictor of postoperative hepatic decompensation. Area under receiver operating characteristic curve for liver stiffness measurement and hepatic venous pressure gradient was 0.81 (95% confidence interval, 0.506-0.907) and 0.71 (95% confidence interval, 0.646-0.917), respectively. Liver stiffness measurement ≥22 kPa had 42.9% sensitivity and 92.6% specificity and hepatic venous pressure gradient ≥10 mm Hg had 28.6% sensitivity and 96.3% specificity. CONCLUSION: In selected patients undergoing liver resection for hepatocellular carcinoma, transient elastography is an easy and effective test to predict persistent hepatic decompensation preoperatively.

RESUMO

BACKGROUND & AIMS: Liver transplantation (LT) for the most severely ill patients with cirrhosis, with multiple organ dysfunction (accurately assessed by the acute-on-chronic liver failure [ACLF] classification) remains controversial. We aimed to report the results of LT in patients with ACLF grade 3 and to compare these patients to non-transplanted patients with cirrhosis and multiple organ dysfunction as well as to patients transplanted with lower ACLF grade. METHODS: All patients with ACLF-3 transplanted in three liver intensive care units (ICUs) were retrospectively included. Each patient with ACLF-3 was matched to a) non-transplanted patients hospitalized in the ICU with multiple organ dysfunction, or b) control patients transplanted with each of the lower ACLF grades (three groups). RESULTS: Seventy-three patients were included. These severely ill patients were transplanted following management to stabilize their condition with a median of nine days after admission (progression of mean organ failure from 4.03 to 3.67, p=0.009). One-year survival of transplanted patients with ACLF-3 was higher than that of non-transplanted controls: 83.9 vs. 7.9%, p<0.0001. This high survival rate was not different from that of matched control patients with no ACLF (90%), ACLF-1 (82.3%) or ACLF-2 (86.2%). However, a higher rate of complications was observed (100 vs. 51.2 vs. 76.5 vs. 74.3%, respectively), with a longer hospital stay. The notion of a "transplantation window" is discussed. CONCLUSIONS: LT strongly influences the survival of patients with cirrhosis and ACLF-3 with a 1-year survival similar to that of patients with a lower grade of ACLF. A rapid decision-making process is needed because of the short "transplantation window" suggesting that patients with ACLF-3 should be rapidly referred to a specific liver ICU. Lay summary: Liver transplantation improves survival of patients with very severe cirrhosis. These patients must be carefully monitored and managed in a specialized unit. The decision to transplant a patient must be quick to avoid a high risk of mortality.

RESUMO

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare severe adverse drug-induced reaction with multiorgan involvement. The outcome and prediction of those patients who develop severe acute liver injury (sALI) or acute liver failure (ALF) remain little known. METHODS: A multicenter retrospective study of patients admitted with a diagnosis of DRESS-related sALI or ALF. Histological review was performed on liver core biopsies from native livers. RESULTS: Sixteen patients (11 women, 5 men; mean age, 39±17.2 years) were classified as having definite (n=13) or probable (n=3) DRESS. At admission, 3 patients had hepatic encephalopathy; median levels of prothrombin time, INR, and total bilirubin were, respectively, 33% (Q1-Q3, 21-41), 2.74 (1.98-4.50), and 94 µmol/L (Q1-Q3, 39.5-243.5). Nine patients received corticosteroid therapy. Overall, 9 patients improved spontaneously and 7 worsened (liver transplantation [LT] (n=5), deceased (n=2)). Transplantation-free and post-LT survival was 56% and 60%, respectively. After LT, DRESS recurrence was observed in 3 of 5 patients. Systemic corticosteroid therapy was not significantly associated with a clinical improvement. In the multivariate analysis, factor V level less than 40% at day 0 and factor V levels of 40% or greater at admission but decreasing at day 2 were associated with worse outcome. Pathological findings (n=7) revealed atypical lymphoid infiltrates, Kupffer cell hyperplasia with erythrophagocytosis, and an inconstant presence of eosinophils. CONCLUSIONS: The spontaneous prognosis of patients with sALI/ALF due to DRESS is poor and was not improved by corticosteroid therapy. Histology is helpful to establish diagnosis. Dynamic variables regarding factor V values are predictive of a poor outcome.

RESUMO

BACKGROUND AND AIMS: First generation protease inhibitors (PI) with peg-interferon (PEG-IFN) and ribavirin (RBV) have been the only therapy available for hepatitis C virus (HCV) genotype 1 infection in most countries for 3 years. We have investigated the efficacy and tolerance of this triple therapy in transplanted patients experiencing a recurrence of HCV infection on the liver graft. PATIENTS: This cohort study enrolled 81 liver transplant patients (Male: 76%, mean age: 55.8±9.7 years) with severe HCV recurrence (F3 or F4: n = 34 (42%), treatment experienced: n = 44 (54%)), treated with boceprevir (n = 36; 44%) or telaprevir (n = 45; 56%). We assessed the percentages of patients with sustained virological responses 24 weeks after therapy (SVR24), and safety. RESULTS: The SVR24 rate was 47% (telaprevir: 42%; boceprevir: 53%, P = ns). At baseline, a normal bilirubin level (p = 0.0145) and albumin level >35g/L (p = 0.0372) and an initial RBV dosage of ≥800 mg/day (p = 0.0033) predicted SVR24. During treatment, achieving an early virological response after 12 weeks was the strongest independent factor to predict SVR24 (p<0.0001). A premature discontinuation of anti-HCV therapy due to a serious adverse event (SAE) was observed in 22 patients (27%). Hematological toxicity, infections and deaths were observed in 95%, 28% and 7% of patients, respectively. A history of post-LT antiviral therapy and thrombocytopenia (<50G/L) during treatment were both independent predictors of the occurrence of infections or SAE (p = 0.0169 and p = 0.011). CONCLUSIONS: The use of first generation PI after liver transplantation enabled an SVR24 rate of 47% in genotype 1 patients, but induced a high rate of SAE. The identification of predictive factors for a response to treatment, and the occurrence of SAE, have enabled us to establish limits for the use of this anti-HCV therapy in the transplant setting.

RESUMO

In France, decisions regarding superurgent (SU) liver transplantation (LT) for patients with acute liver failure (ALF) are principally based on the Clichy-Villejuif (CV) criteria. The aims of the present study were to study the outcomes of patients registered for SU LT and the factors that were predictive of spontaneous improvement and to determine the usefulness of the CV criteria. All patients listed in France for SU LT between 1997 and 2010 who were 15 years old or older with ALF were included. In all, 808 patients were listed for SU transplantation: 22% with paracetamol-induced ALF and 78% with non-paracetamol-induced ALF. Of these 808 patients, 112 improved spontaneously, 587 underwent LT, and 109 died or left the waiting list because of a worsening condition. The 1-year survival rate according to an intention-to-treat analysis and the survival after LT were 66.3% [interquartile range (IQR), 62.7%-69.7%] and 74.2% (IQR, 70.5%-77.6%), respectively. The factors that were predictive of a spontaneous recovery with ALF-related paracetamol hepatotoxicity were as follows: hepatic encephalopathy grade 0, 1, or 2 [odds ratio (OR), 4.8; 95% confidence interval (CI), 1.99-11.6]; creatinine clearance≥60 mL/minute/1.73 m2 (OR, 4.77; 95% CI, 1.96-11.63), a bilirubin level<200 µmol/L (OR, 21.64; 95% CI, 1.76-265.7); and a factor V level>20% (OR, 5.79; 95% CI, 1.66-20.29). For ALF-related nonparacetamol hepatotoxicity, the factor that was predictive of a spontaneous recovery was a bilirubin level<200 µmol/L (OR, 10.38; 95% CI, 4.71-22.86). The sensitivity, specificity, and positive and negative predictive values for the CV criteria were 75%, 56%, 50%, and 79%, respectively, for ALF due to paracetamol and 69%, 50%, 64%, and 55%, respectively, for ALF not related to paracetamol. The performance of current criteria for SU transplantation could be improved if paracetamol-induced ALF and non-paracetamol-induced ALF were split and 2 other items were included in this model: the bilirubin level and creatinine clearance.

RESUMO

OBJECTIVE: Severe hepatitis C virus (HCV) recurrence affects post-transplant survival in HIV/HCV co-infected patients. This article describes the results of triple anti-HCV therapy with boceprevir or telaprevir in seven HIV/HCV co-infected patients following liver transplantation. METHODS: All patients had severe HCV recurrence [fibrosis stage ≥F2 or acute hepatitis ≥A2 (n = 5) or fibrosing cholestatic hepatitis (n = 2)] associated with genotype 1a (n = 4) or 1b (n = 3). Patients were treated with Peg-interferon/ribavirin and boceprevir (n = 2) or telaprevir (n = 5) immediately (n = 3) or after a 4-week lead-in phase (n = 4). Immunosuppression included either cyclosporine (n = 5) or tacrolimus (n = 2). Prior to introducing telaprevir, combined antiretroviral therapy was switched in one patient to prevent drug-drug interactions. RESULTS: At 24 weeks after the end of treatment, sustained virological response was observed in 60% (3/5) of the patients treated with telaprevir; no responders were observed in the boceprevir group. Triple anti-HCV therapy was prematurely discontinued in six patients [treatment failure (n = 2), infection (n = 2), acute rejection (n = 1) and myocardial infarction (n = 1)]. Anaemia occurred in all patients, requiring erythropoietin, ribavirin dose reduction and red blood cell transfusions in five patients.Average cyclosporine doses were reduced by 50-84% after telaprevir initiation and by 33% after boceprevir initiation. Tacrolimus doses were reduced by 95% with telaprevir. CONCLUSION: Our data suggest that in HIV/HCV co-infected patients, triple anti-HCV therapy with telaprevir greatly improved efficacy despite poor tolerability. Significant decreases in cyclosporine or tacrolimus doses are necessary prior to introduction of boceprevir or telaprevir. Close monitoring is essential to prevent drug-drug interactions among antiretroviral therapy, immunosuppressive agents and anti-HCV therapy.

RESUMO

BACKGROUND & AIMS: Protease inhibitors (PI) with peginterferon/ribavirin have significantly improved SVR rates in HCV G1 patients. Their use to treat HCV recurrence after liver transplantation (LT) is a challenge. METHODS: This cohort study included 37 liver transplant recipients (male, 92%, age 57 ± 11 years), treated with boceprevir (n=18) or telaprevir (n=19). The indication for therapy was HCV recurrence (fibrosis stage ≥F2 (n=31, 83%) or fibrosing cholestatic hepatitis (n=6, 16%). RESULTS: Eighteen patients were treatment-naive, five were relapsers and fourteen were non-responders to dual therapy after LT. Twenty-two patients received cyclosporine and fifteen tacrolimus. After 12 weeks of PI therapy, a complete virological response was obtained in 89% of patients treated with boceprevir, and 58% with telaprevir (p=0.06). The end of treatment virological response rate was 72% (13/18) in the boceprevir group and 40% (4/10) in the telaprevir group (p=0.125). A sustained virological response 12 weeks after treatment discontinuation was observed in 20% (1/5) and 71% (5/7) of patients in the telaprevir and boceprevir groups, respectively (p=0.24). Treatment was discontinued in sixteen patients (treatment failures (n=11), adverse events (n=5)). Infections occurred in ten patients (27%), with three fatal outcomes (8%). The most common adverse effect was anemia (n=34, 92%), treated with erythropoietin and/or a ribavirin dose reduction; thirteen patients (35%) received red blood cell transfusions. The cyclosporine dose was reduced by 1.8 ± 1.1-fold and 3.4 ± 1.0-fold with boceprevir and telaprevir, respectively. The tacrolimus dose was reduced by 5.2 ± 1.5-fold with boceprevir and 23.8±18.2-fold with telaprevir. CONCLUSIONS: Our results suggest that triple therapy is effective in LT recipients, particularly those experiencing a severe recurrence. The occurrence of anemia and drug-drug interactions, and the risk of infections require close monitoring.

RESUMO

Hepatitis C virus (HCV) recurrence is the most important complication in HCV liver transplant patients. Boceprevir with pegylated interferon and ribavirin (PegIFN/RBV) enabled improvement in sustained virological response rates of patients with genotype 1 HCV. Boceprevir interacts with immunosuppressive therapy (IT) by inhibiting the cytochrome P450 3A enzyme. Our aim was to study interactions and assess the safety of boceprevir in the context of HCV recurrence. Boceprevir (800 mg three times a day) initiated after a 4-week lead-in phase was associated with cyclosporine (three patients), tacrolimus (two patients), and everolimus (one patient) in five liver transplant patients with genotype 1 HCV infection who experienced HCV recurrence. The mean follow-up period after HCV therapy was 14.8 ± 3.1 weeks. Estimated oral clearances of IT decreased on average by 50%, requiring reduced dosing regimens. Anemia occurred in all patients, with a mean fall in hemoglobin levels between baseline and week 12 of 3.12 ± 2.27 g/dl. All patients required administration of ß-erythropoietin (n = 5), three needed ribavirin dose reduction, and one needed a blood transfusion. A virological response was observed in all patients (mean HCV viral load [HVL] decrease at week 12, 6.64 ± 0.35 log(10) IU/ml). These preliminary results in liver transplant patients with HCV recurrence demonstrate the feasibility and safety of coadministration of boceprevir and IT.

RESUMO

BACKGROUND & AIMS: Most liver transplant centres have discontinued the practice of protocol liver biopsies (LB), mainly because of the perceived lack of therapeutic benefit. This study aimed to examine the usefulness of 20-year LBs. METHODS: Ten, 15, and 20-year protocol LBs from 147 patients surviving for >20 years were reviewed. Twenty-year biopsy findings were correlated with clinical data. RESULTS: Twenty-year-biopsy patients (N=91) and 20-year-non-biopsy patients (N=56) were similar in terms of transplant data, adverse events, and liver function tests (LFTs). Twenty-year LBs revealed a 90% prevalence of abnormalities, among which viral chronic hepatitis (VCH) was the most common (46%). Between 15 and 20 years, hepatic structural abnormalities were the only disorder to increase (p=0.008). An individual progression of abnormalities occurred in 56% of patients. At 20 years, the negative and positive predictive values (PV) of LFTs with respect to histological abnormalities were 95% and 18%, respectively; in VCH, Fibrotest and transient elastography displayed poor discriminative ability for fibrosis (80% and 81% discordance, respectively), but were satisfactory regarding significant fibrosis (negative PV of 77.7% and 80%, respectively). A decrease in immunosuppression was less frequent (14/91 vs. 20/56, p=0.008) while an increase was more common (15/91 vs. 2/56, p=0.017) in 20-year-biopsy patients than in non-biopsy patients. Antiviral therapy was administered in seven of the 20-year biopsy patients, but in none of the non-biopsy patients (p=0.04). CONCLUSIONS: Twenty-year LBs provided important histological information on graft function that was available to a limited degree from LFTs and non-invasive markers. They exerted an impact on immunosuppressive and antiviral therapies.

RESUMO

The standard antitubercular treatment (ATT), which consists of isoniazid (INH), rifampicin (RIF), ethambutol, and pyrazinamide (PZA), is the best available treatment for tuberculosis (TB). However, the hepatotoxicity of INH and PZA can be severe, and even after drug withdrawal, patients may require liver transplantation (LT). In these cases, the strategy for the treatment of TB is poorly defined. Between 1986 and 2008, 14 patients presented at our department with severe hepatitis secondary to INH and PZA treatment. Four of these patients were immunosuppressed: 2 after renal transplantation and 2 because of human immunodeficiency virus infection. In seven of the 14 patients an alternative ATT was begun on admission, which was well tolerated. Hepatitis improved spontaneously in 5 patients, and alternative ATT was continued for 9.3 ± 4.2 months; 1 patient deteriorated and underwent LT, and 1 patient died. ATT was stopped definitively in 2 patients. Six patients required urgent LT, and alternative ATT was started after transplantation and was successful. Five patients receiving RIF had an episode of acute rejection. In conclusion, hepatitis secondary to ATT can be successfully treated with alternative anti-TB regimens. The use of RIF in LT patients may lead to acute rejection. RIF should therefore be avoided in these patients.

RESUMO

BACKGROUND: In patients coinfected with hepatitis B virus (HBV) and human immunodeficiency virus (HIV), evolution toward cirrhosis and its complications is more rapid and severe than in patients infected with HBV alone. The outcome of liver transplantation in HBV-HIV-coinfected patients is poorly understood in terms of survival rate, HBV reactivation and mitochondrial toxicity on the liver graft. PATIENTS AND METHODS: Between November 2002 and June 2007, 13 HIV-positive patients underwent liver transplantation because of end-stage liver disease due to HBV with or without coinfection with hepatitis D or C virus. These patients were prospectively followed for an average of 32 +/- 5.2 months (range 10-63 months). RESULTS: All patients were alive at the end of the follow-up period and had normal liver function. Their HBV viral load was undetectable, no cccDNA was found in the liver graft and HIV infection was nonprogressive under antiretroviral therapy. Moreover, no mitochondrial toxicity was noted in the liver graft, as assessed by the spectrophotometric analysis of respiratory chain activities and by quantifying the mitochondrial DNA copy number. CONCLUSION: HBV-HIV-coinfected patients can successfully undergo liver transplantation with excellent results in terms of survival, control of HBV replication after transplantation and mitochondrial toxicity.

RESUMO

Statins and fibrates have different effects on lipid abnormalities of familial combined hyperlipidemia (FCHL); thus, the selection of the first-line drug is troublesome. We evaluated to what extent monotherapy with a potent statin is more effective than fibrate in reaching the recommended lipid targets in FCHL. Fifty-six patients were randomized to receive optimal dosage of atorvastatin (n = 27) or 200 mg/d micronized fenofibrate (n = 29) for 24 weeks. To reach the optimal dosage, atorvastatin was up-titrated at each follow-up visit if low-density lipoprotein (LDL) cholesterol >130 mg/dL (>100 mg/dL in patients with coronary or cerebrovascular disease). The effects of fenofibrate and atorvastatin on lipoprotein fractions as well as on plasma levels of endothelin-1 (ET-1) and adrenomedullin (AM) were also evaluated. At end of trial, a greater proportion of patients on atorvastatin (average dosage, 20.8 mg/d) reached lipid targets in comparison with those on fenofibrate (64% vs 32.1%, P = .02). Atorvastatin was significantly more effective in reducing total cholesterol, LDL cholesterol, apolipoprotein B, and non-high-density lipoprotein (HDL) cholesterol. Conversely, triglycerides decreased and HDL increased more during fenofibrate. Nevertheless, atorvastatin produced a marked reduction in very low-density lipoprotein and very low-density lipoprotein remnants. Atorvastatin lowered all LDL subtypes, although fenofibrate appeared to be more effective on denser LDL. Compared with 43 normolipemic controls, FCHL patients presented increased baseline plasma levels of ET-1 (P = .007) but not of AM. Fenofibrate, but not atorvastatin, significantly lowered ET-1 levels by 16.7% (P < .05). Neither drug significantly affected plasma concentrations of AM. In summary, although fenofibrate showed superiority in raising HDL and reducing ET-1, atorvastatin was more effective in reaching lipid targets in FCHL so that it can be proposed as the first-line option in the management of this atherogenic hyperlipidemia.
