Sarcopenia is associated with reduced survival in patients with advanced hepatocellular carcinoma undergoing sorafenib treatment.

BACKGROUND: Sarcopenia has been associated with poor outcomes in patients with cirrhosis and solid tumours. OBJECTIVE: Analyse the influence of sarcopenia on survival and treatment duration in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib. METHODS: We conducted a multicentre, retrospective study on 96 patients with advanced HCC treated with sorafenib, all with available abdominal computed tomography (CT) scan within 30 days from treatment start. Anthropometric, laboratory, treatment and follow-up data were collected. Sarcopenia was defined by reduced skeletal muscle index calculated from an L3 section CT image. RESULTS: Sarcopenia was present in 49% of patients. Patients were divided into two groups according to sarcopenia: age was significantly higher in the sarcopenic group (SG) (66 years (31-87) versus 72 years (30-84), p = 0.04], with no difference in other baseline characteristics. The SG showed shorter overall survival (OS) (39 (95% confidence interval (CI) 26-50) versus 61 (95% CI 47-77) weeks (p = 0,01)) and shorter time on treatment (12.3 (95% CI 8-19) versus 25.9 (95% CI 15-33) weeks (p = 0.0044)). At multivariate analysis, sarcopenia was independently associated to reduced OS (p = 0.03) and reduced time on treatment (p = 0.001). CONCLUSION: Sarcopenia is present in almost half of patients with advanced HCC, and is associated with reduced survival and reduced duration of oral chemotherapy.

Lack of reduction in serum alpha-fetoprotein during treatment with direct antiviral agents predicts hepatocellular carcinoma development in a large cohort of patients with hepatitis C virus-related cirrhosis.

Risk of hepatocellular carcinoma (HCC) in hepatitis C virus cirrhotic patients treated with direct-acting antiviral agents (DAA) is still debating. We investigated it in a large cohort. The cohort comprised 1045 cirrhotic patients who completed treatment with DAA, with a median follow-up of 17.3 months after end of treatment (EOT), including 943 patients without history of HCC and 102 previously treated for HCC. The majority were men (59.9%), with compensated cirrhosis (88.8%), genotype 1b (44.7%). Univariate, multivariate analysis and Kaplan-Meier curves were performed to detect predictors of HCC in patients with and without reduction in alpha-fetoprotein (AFP) during treatment. SVR12 was 95.6%. HCC developed in 95 (9.9%), including 54 of 943 (5.7%) occurrent and 41 of 102 (39%) recurrent tumours. De novo were more often unifocal (P = 0.01) and curable (P = 0.03). AFP decreased from 16.1 ± 36.2 mg/dL (baseline) to 11.4 ± 55 mg/dL (EOT). At univariate analysis, predictors were a previous HCC, older age, higher model for end-stage liver disease, prolonged INR, lower platelets, baseline and EOT AFP, virological failure and no reduction in AFP during treatment. Kaplan-Meier curves showed lower incidence of HCC in patients showing any reduction in AFP (P = 0.001). Those with AFP <6 ng/mL had the lowest risk (P = 0.0002). At logistic regression, platelets (P = 0.009, OR 0.99 CI: 0.99-1.00), previous HCC (P < 0.000 01, OR: 10.76, 95% CI: 5.89-19.34) and no reduction in AFP during treatment (P = 0.0005, OR: 2.98, CI: 1.60-5.54) were independent predictors of HCC. In conclusion, risk of HCC after DAA treatment remains substantial. It is higher among patients with previous HCC, low platelets and without reduction in AFP during treatment.

Yttrium-90 Radioembolization for Hepatocellular Carcinoma Prior to Liver Transplantation.

BACKGROUND: Liver transplantation (LT) is a well-established procedure for hepatocellular carcinoma (HCC) within the Milan criteria. Yttrium-90 microspheres radioembolization (Y90-RE) has shown to be an effective and safe treatment of primary liver tumors. We retrospectively evaluate the efficacy of the Y90-RE in patients with HCC prior to LT. METHODS: From January 2002 to December 2015, 365 patients were transplanted at the San Camillo Hospital Center. One hundred forty-three patients were transplanted for HCC, and in 22 cases the patients were treated with Y90-RE before LT. RESULTS: Three patients were treated with Y90-RE within the Milan criteria, and 19 patients were out of criteria before Y90-RE. Four patients had an increasing MELD score between Y90-RE and LT. On the other hand, alpha-fetoprotein decreases after Y90-RE treatment in all cases. No patient death was observed in Y90-RE procedure or at LT. In 78.9 % of cases, a successful downstaging was observed, and in 100 % of cases bridging was achieved. From Y90-RE treatment overall survival was 43.9 months. From LT, overall mean survival was 30.2 months with a free survival of 29.6 months. The overall survival after LT analysis between the patients treated with Y90-RE and patients without was not significant (p = 0.113). Free survival analysis was not significant (p = 0.897) between the two populations. CONCLUSIONS: We successfully performed LT in patients after Y90-RE treatment both as bridging and downstaging for HCC and obtained a similar overall and free survival of LT for HCC within Milan criteria. Y90-RE becomes a real option to provide curative therapy for patients who traditionally are not considered eligible for surgery.

Daclatasvir combined with sofosbuvir or simeprevir in liver transplant recipients with severe recurrent hepatitis C infection.

Daclatasvir (DCV) is a potent, pangenotypic nonstructural protein 5A inhibitor with demonstrated antiviral efficacy when combined with sofosbuvir (SOF) or simeprevir (SMV) with or without ribavirin (RBV) in patients with chronic hepatitis C virus (HCV) infection. Herein, we report efficacy and safety data for DCV-based all-oral antiviral therapy in liver transplantation (LT) recipients with severe recurrent HCV. DCV at 60 mg/day was administered for up to 24 weeks as part of a compassionate use protocol. The study included 97 LT recipients with a mean age of 59.3 ± 8.2 years; 93% had genotype 1 HCV and 31% had biopsy-proven cirrhosis between the time of LT and the initiation of DCV. The mean Model for End-Stage Liver Disease (MELD) score was 13.0 ± 6.0, and the proportion with Child-Turcotte-Pugh (CTP) A/B/C was 51%/31%/12%, respectively. Mean HCV RNA at DCV initiation was 14.3 × 6 log10 IU/mL, and 37% had severe cholestatic HCV infection. Antiviral regimens were selected by the local investigator and included DCV+SOF (n = 77), DCV+SMV (n = 18), and DCV+SMV+SOF (n = 2); 35% overall received RBV. At the end of treatment (EOT) and 12 weeks after EOT, 88 (91%) and 84 (87%) patients, respectively, were HCV RNA negative or had levels <43 IU/mL. CTP and MELD scores significantly improved between DCV-based treatment initiation and last contact. Three virological breakthroughs and 2 relapses occurred in patients treated with DCV+SMV with or without RBV. None of the 8 patient deaths (6 during and 2 after therapy) were attributed to therapy. In conclusion, DCV-based all-oral antiviral therapy was well tolerated and resulted in a high sustained virological response in LT recipients with severe recurrent HCV infection. Most treated patients experienced stabilization or improvement in their clinical status.

Cholestatic hepatitis C after chemotherapy containing rituximab in diffuse large B cell lymphoma.

Rituximab is a chimeric anti-CD20 monoclonal antibody that is a widely used for the treatment of B cells non-Hodgkin lymphoma. The use of chemotherapy regimens containing rituximab in HCV-positive patients with non-Hodgkin lymphoma has been associated with liver dysfunction, but no cases of cholestatic hepatitis C were described. To our knowledge, this is the first case of cholestatic hepatitis C in an HCV-positive patient with diffuse large B-cell lymphoma describes in the literature. We discuss the pathogenetic mechanisms underlying this severe form of hepatitis and describe its evolution after antiviral treatment.

Long term nucleotide and nucleoside analogs treatment in chronic hepatitis B HBeAg negative genotype D patients and risk for hepatocellular carcinoma.

UNLABELLED: BACKGROUND AND RATIONALE OF THE STUDY: Effect of Long-term nucleoside/nucleotide (NUC) on hepatocellular carcinoma (HCC) incidence in a population of HBeAg-negative genotype D patients has not been adequately studied in real-life cohorts. Our aim was to evaluate the impact of liver fibrosis and other variables on HCC incidence in this population of patients. Of 745 patients with chronic hepatitis B (CHB), 306 HBeAg-negative genotype D were selected and included in this study. All patients received treatment with NUC for at least 18 months. Patients with CHB or compensated cirrhosis were included. Patients with HCC diagnosed before or during the first 18 months of NUC therapy were excluded. RESULTS: HCC was diagnosed in 2 CHB patients (1.0%) and 23 cirrhosis patients (20%) (OR = 24.41, 95% CI 5.40 < OR < 153.2; p < 0.0001). Multivariate analysis revealed that HCC risk was independently associated with age ≥ 60 years (OR = 6.45, 95% CI 1.22 to 34.0; p = 0.02) and liver cirrhosis (OR = 12.1, 95% CI 1.39 to 106.2; p = 0.02), but not with virological response (VR), and previous resistance to NUC, or rescue therapy. Multivariate analysis in cirrhosis patients revealed that only age ≥ 60 years was an independent risk factor associated with HCC (p = 0.003). CONCLUSIONS: Liver cirrhosis and age ≥ 60 years are the stronger risk factors for HCC in genotype D HBeA-gnegative patients. Previous resistance to NUC in patients that achieved a VR after rescue therapy was not a predictive factor regarding HCC. VR does not appear to significantly reduce the overall incidence of HCC when a patient has already progressed to liver cirrhosis.

HCV genotype 1a shows a better virological response to antiviral therapy than HCV genotype 1b.

BACKGROUND: The impact of viral subtype on the rate of sustained virological response (SVR) to antiviral therapy in patients chronically infected with hepatitis C genotype 1 subtype 1a and 1b has not been extensively investigated. The aim of this study is to determine whether the HCV genotype 1 subtypes 1a and 1b respond differently to treatment with PEGylated interferon (PEG-IFN) plus ribavirin. METHODS: For 48 weeks, 388 "naïve"genotype 1 patients were treated weekly with PEG-IFN α-2a or PEG-INF α-2b combined with daily ribavirin (1000-1200 mg/day). The numbers of patients in whom HCV-RNA was undetectable were compared after 4 (rapid virological response, RVR), 12 (early virological response, EVR), and 48 (end treatment virological response, ETR) weeks of treatment as well as 24 weeks after the last treatment (sustained virological response, SVR). RESULTS: The rate of SVR was higher in subtype 1a patients than subtype 1b patients (55% vs. 43%; p < 0.02). Multiple logistic regression analysis showed that infection with genotype 1a (odds ratio(OR) : 1.8; 95% confidence interval (CI): 1.4 to 4.1), age < 50 years (OR:7.0; 95% CI 1.1 to 21.2), alanine aminotransferase level (ALT)<100 IU/ml (OR:2.1; 95% CI: 1.3 to3.5), HCV-RNA < 5.6 log10 IU/ml (OR: 3.2; 95% CI: 2.7 to 6.9) and fibrosis score < S3 (OR: 3.8; 95% CI:3.2 to 7.4), were all independent predictors of SVR. CONCLUSION: Dual antiviral therapy is more effective against HCV subtype 1a than against subtype 1b and this difference is independent of other factors that may favour viral clearance.

Porphyria cutanea tarda in an HCV-positive liver transplant patient: a case report.

INTRODUCTION: Porphyria cutanea tarda (PCT) is the most common type of porphyria. The strong association between PCT and hepatitis C virus (HCV) infection is well established. Although antiviral treatment of chronic hepatitis C may improve PCT in some cases, de novo onset of PCT has been observed in patients under- going peginterferon/ribavirin treatment. We present a rare case of a genotype 3 HCV-positive liver transplant recipient who developed PCT during antiviral treatment and discuss its probable etiopathogenesis. CASE PRESENTATION: A genotype 3 HCV-positive liver transplant recipient, a 42-year-old man, was treated with peginterferon alfa-2a (180 µg/week) combined with ribavirin (1,200 mg/day) for recurrence of HCV infection after liver transplantation. He presented with hyperferritinemia but tested negative for genetic hemochromatosis (C282Y and H63D mutations). During antiviral therapy, he developed skin lesions on his hands characterized by vesicles and erosions consistent with PCT. PCT was confirmed by skin biopsy and elevated urinary uroporphyrin levels (1,469 mg/24 h). He was treated with chloroquine (200 mg) twice weekly, resulting in gradual regression of the skin lesions. Antiviral treatment was stopped after 48 weeks, and the patient achieved a sustained virological response. In conclusion, we report an extremely rare case of PCT in a genotype 3 HCV-positive liver transplant patient treated with antiviral therapy. We believe that the combination of HCV genotype 3 infection; hemolysis due to ribavirin treatment; and increased plasma levels of cytokines, such as IL-6 and TNFα, could have altered the patient's iron metabolism and thus caused PCT.

'Les liaisons dangereuses': Hepatitis C, Rituximab and B-cell non-Hodgkin's lymphomas.

Rituximab has provided a revolutionary contribution to the treatment of B-cell non-Hodgkin's lymphomas (NHL). A high prevalence of hepatitis C virus (HCV) infection has been described in B-cell NHL patients. Cases of liver dysfunction in HCV-positive patients have been reported with Rituximab-containing regimens. In this paper we review the recent data regarding the effects of Rituximab in NHL patients with HCV infection. We also added a section devoted to improving communication between oncohaematologists and hepatologists. Furthermore, we propose a common methodological ground to study hepatic toxicity emerging during chemotherapy.

Hepatitis C virus-related B cell subtypes in non Hodgkin's lymphoma.

AIM: To evaluate if indolent B cell-non Hodgkin's lymphoma (B-NHL) and diffuse large B-cell lymphoma (DLBCL) in hepatitis C virus (HCV) positive patients could have different biological and clinical characteristics requiring different management strategies. METHODS: A group of 24 HCV related B-NHL patients (11 indolent, 13 DLBCL) in whom the biological and clinical characteristics were described and confronted. Patients with DLBCL were managed with the standard of care of treatment. Patients with indolent HCV-related B-NHL were managed with antiviral treatment pegylated interferon plus ribavirin and their course observed. The outcomes of the different approaches were compared. RESULTS: Patients with DLBCL had a shorter duration of HCV infection and a higher prevalence of HCV genotype 1 compared to patients with indolent B-NHL in which HCV genotype 2 was the more frequent genotype. Five of the 9 patients with indolent HCV-related B-NHL treated with only antiviral therapy, achieved a complete response of their onco-haematological disease (55%). Seven of the 13 DLBCL patients treated with immunochemotheraphy obtained a complete response (54%). CONCLUSION: HCV genotypes and duration of HCV infection differed between B-NHL subtypes. Indolent lymphomas can be managed with antiviral treatment, while DLBCL is not affected by the HCV infection.

Plasma cytokines and portopulmonary hypertension in patients with cirrhosis waiting for orthotopic liver transplantation.

Portopulmonary hypertension (PPHTN) is a rare complication in patients with portal hypertension. A role of endothelin 1 (ET-1) and other cytokines was demonstrated in primary pulmonary hypertension but not in PPHTN. We evaluated the possible role of ET-1, interleukin 6 (IL-6), interleukin 1ß (IL-1ß), and tumor necrosis factor alpha (TNF-α) in the pathogenesis of PPHTN. Plasmatic concentrations of ET-1, IL-6, IL-1ß, and TNF-α were measured in patients with pulmonary systolic arterial pressure (PAPs) >30 mm Hg and in patients with cirrhosis. In all, Six out of 11 patients with PAPs >30 mm Hg had PPHTN on right heart catheterization. The remaining 10 patients had an hyperdynamic circulation (HC). In PPHTN patients, ET-1 and IL-6 were significantly higher compared with HC and patients with cirrhosis. Endothelin 1 and IL-6 could be implicated in the pathogenesis of PPHTN. On the basis of these results, ET-1 receptor antagonists or anti-IL-6 could have a rationale in the treatment of PPHTN.

Liver cirrhosis and rhino-orbital mucormycosis, a possible but rare association: description of a clinical case and literature review

Only few cases of rhino-orbital mucormycosis in patients with liver cirrhosis are described in the literature and most of these patients showed an associated diabetes mellitus. We describe a case of rhino-orbital mucormycosis in a patient with liver cirrhosis without other risk factors.

Contrast echocardiography of right atrial mass due to hepatocellular carcinoma.

We describe one patient suffering from hepatocellular carcinoma who presented with a right atrial metastatic tumour as a result of invasion of the inferior vena cava and extension into the right atrium. Two-dimensional echocardiography disclosed the right atrium tumour and SonoVue contrast agent echocardiography was employed to assess the local extension of the mass and to exclude an important obstruction due to a mass in the right ventricular inflow. Surgical management in the presence of metastatic right atrial tumour thrombus is described in the literature with poor results and this type of treatment should be reserved only for selected cases in which acute and severe cardiovascular distress due to obstruction of right ventricular inflow is present.
