Factors affecting long-term changes of liver stiffness in direct-acting anti-hepatitis C virus therapy: A multicentre prospective study.

The long-term changes of liver stiffness (LS) in patients who achieve viral clearance after direct-acting anti-HCV therapy remain undefined. We conducted a multicentre prospective study to investigate this aspect. Patients with HCV infection treated with DAAs were enrolled from six Italian centres; they underwent clinical, biochemical, ultrasound and transient elastography evaluations before treatment (T0), 12 weeks (SVR12) and 24 months (T24) after the end of therapy. Among the 516 consecutive patients enrolled, 301 had cirrhosis. LS significantly decreased from T0 to SVR (14.3 vs 11.1 kPa, p = .002), with a progressive reduction until T24 (8.7 kPa, p < .001). However, only patients with steatosis and those who developed HCC did not experience a late improvement in LS. Multivariate analysis of baseline and follow-up variables identified steatosis as the only independent predictor of failure of LS improvement (OR 1.802, p = .013). ROC curve analysis of the association of LS with the risk of developing HCC showed that SVR12 ≥14.0 kPa had the highest accuracy (sensitivity 82%, specificity 99%; AUC: 0.774). Multivariate analysis revealed that LS was the only variable independently associated with an increased risk of developing HCC (OR 6.470, p = .035). Achieving an SVR was associated with a progressive, long-term decline of LS, suggesting a late improvement in liver fibrosis, besides the resolution of inflammation. Fatty liver and the development of HCC interfered with late reduction of LS. Patients with an LS ≥14 kPa at 12 weeks after the end of treatment were at higher risk for developing HCC.

Quality of life in liver transplant recipients during the Corona virus disease 19 pandemic: A multicentre study.

BACKGROUND: Liver transplant recipients require specific clinical and psychosocial attention given their frailty. Main aim of the study was to assess the quality of life after liver transplant during the current pandemic. METHODS: This multicentre study was conducted in clinically stable, liver transplanted patients. Enrollment opened in June and finished in September 2021. Patients completed a survey including lifestyle data, quality of life (Short Form health survey), sport, employment, diet. To examine the correlations, we calculated Pearson coefficients while to compare subgroups, independent samples t-tests and ANOVAs. To detect the predictors of impaired quality of life, we used multivariable logistic regression analysis. RESULTS: We analysed data from 511 patients observing significant associations between quality of life's physical score and both age and adherence to Mediterranean diet (p < .01). A significant negative correlation was observed between mental score and the sedentary activity (p < .05). Female patients scored significantly lower than males in physical and mental score. At multivariate analysis, females were 1.65 times more likely to report impaired physical score than males. Occupation and physical activity presented significant positive relation with quality of life. Adherence to Mediterranean diet was another relevant predictor. Regarding mental score, female patients were 1.78 times more likely to show impaired mental score in comparison with males. Sedentary activity and adherence to Mediterranean diet were further noteworthy predictors. CONCLUSIONS: Females and subjects with sedentary lifestyle or work inactive seem to show the worst quality of life and both physical activity and Mediterranean diet might be helpful to improve it.

Predictors of solid extra-hepatic non-skin cancer in liver transplant recipients and analysis of survival: A long-term follow-up study.

INTRODUCTION AND OBJECTIVES: De novo malignancies represent an important cause of death for liver transplant recipients. Our aim was to analyze predictors of extra-hepatic non-skin cancer (ESNSC) and the impact of ESNSC on the long-term outcome. PATIENTS: We examined data from patients transplanted between 2000 and 2005 and followed-up in five Italian transplant clinics with a retrospective observational cohort study. Cox Regression was performed to identify predictors of ESNSC. A 1:2 cohort sub-study was developed to analyze the impact of ESNSC on 10-year survival. RESULTS: We analyzed data from 367 subjects (median follow-up: 15 years). Patients with ESNSC (n = 47) more often developed post-LT diabetes mellitus (DM) (57.4% versus 35,9%, p = 0.004). At multivariate analysis, post-LT DM independently predicted ESNSC (HR 1.929, CI 1.029-3.616, p = 0.040). Recipients with ESNSC showed a lower 10-year survival than matched controls (46,8% versus 68,1%, p = 0.023). CONCLUSIONS: Post-LT DM seems to be a relevant risk factor for post-LT ESNSC. ESNSC could have a noteworthy impact on the long-term survival of LT recipients.

Incidence and risk factors of early HCC occurrence in HCV patients treated with direct acting antivirals: a prospective multicentre study.

BACKGROUND: An unexpected increased HCC recurrence and occurrence rate among HCV patients treated with direct acting antivirals combination has been reported. Aim of the study was the evaluation of early HCC occurrence rate and its risk factors in a HCV infected population, treated with direct-acting-antivirals. METHODS: According to the Italian ministerial guidelines for direct-acting-antivirals treatment, 1022 consecutive HCV patients treated with direct-acting-antivirals were enrolled. Patients either with active HCC at imaging or history of previous treated HCC, HBV or HIV co-infection, or liver transplant recipients were excluded. The SVR, defined as the persistent absence of detectable serum HCV-RNA 12 weeks after the end of treatment (SVR12), was assessed for all enrolled patients. Abdominal ultrasound was performed before starting antiviral therapy, and repeated every 6 months. HCC was diagnosed according to the international guidelines. Patients showing either nodular patterns suggestive of HCC or with uncertain dynamic vascular behaviour were excluded from a further follow-up. RESULTS: Nine hundred and eighty-five patients completed the 48 weeks follow-up after the end of treatment. A Sofosbuvir-based regimen was administered in the 74.9% of patients, among whom, the 71.6% underwent a simultaneous Ribavirin administration. A sustained virological response at 12 weeks off treatment was documented in 966 patients (98.2%). During the post treatment follow-up HCC was detected in 35 patients, with a cumulative incidence rate of the 3.55%. At multivariate analysis, four variables resulted independently associated with HCC development, both in a cirrhosis based and a class B Child based model, respectively: cirrhosis/class B Child, therapeutic schedule including Sofosbuvir without Ribavirin, liver stiffness values, male gender and presence of diabetes. A multivariate analysis performed on Child A cirrhotic patients, showed that Sofosbuvir based therapeutic treatment without Ribavirin had a HCC occurrence 5.7 higher than Ribavirin-based schedules with or without Sofosbuvir (p < 0.0001, OR: 5.686, 95% CI 2.455-13.169). CONCLUSIONS: Our data suggest that early HCC occurrence appears more frequently related to Sofosbuvir-based therapy without Ribavirin which, indeed, seems to play a protective role on HCC onset. Therefore, a careful follow-up should be mandatory, especially in those regimens including Sofosbuvir without Ribavirin.

Role of Liver Stiffness Measurement in Predicting HCC Occurrence in Direct-Acting Antivirals Setting: A Real-Life Experience.

PURPOSE: The aim of this study was to evaluate the relationship between the liver stiffness measurement and the risk of developing hepatocellular carcinoma (HCC) in HCV cirrhotic patients undergoing new direct-acting antivirals. METHODS: From April 2015 to April 2017, all consecutive HCV cirrhotic patients treated by direct-acting antivirals were enrolled. A liver stiffness measurement was computed at baseline, and an ultrasound evaluation was provided for all patients at baseline and every 6 months until 1 year after the stopping of the antiviral therapy. The diagnosis of HCC was performed according to international guidelines by imaging technique workup. RESULTS: Two hundred and fifty-eight HCV patients with a diagnosis of cirrhosis were identified. The median liver stiffness was 25.5 kPa. Thirty-five patients developed HCC. Patients were divided into three groups, based on their liver stiffness: < 20 kPa (n = 72), between 20 and 30 kPa (n = 92) and > 30 kPa (n = 94). Compared to the < 20 kPa and 20-30 kPa groups, the > 30 kPa group showed a statistically significant increased risk of HCC (p = 0.019; HR 0.329; 95% CI 0.131-0.830). A ROC curve analysis to assess the overall predictive performance of liver stiffness measurement on the HCC risk was performed. The results allow us to identify a cutoff value of liver stiffness measurement equal to 27.8 kPa, which guarantees the highest sensitivity and specificity (respectively, 72% and 65%). CONCLUSIONS: The data underline that the baseline liver stiffness measurement and ultrasound surveillance is a valuable tool for assessing the risk of HCC in cirrhotic patients undergoing the direct-acting antivirals treatment.

Influence of antiviral therapy on the liver stiffness in chronic HBV hepatitis.

PURPOSE: The aim of this study was to evaluate the effects of antiviral therapy on liver stiffness measurement (LSM). METHODS: Two hundred HBV patients were enrolled from four hospital centers in southern Italy; median age was 50.7 (25-75) males were 68%; 171 patients underwent to liver biopsy and 200 patients had LSM at baseline and 189 at the end of follow-up. One hundred and forty-nine patients were treated with nucleos(t)ide analogs, while 51 patients were untreated. The cutoffs of the LSM, related to the fibrosis stages, were as follows: non-advanced fibrosis ≤ 8.1 kPa and advanced fibrosis ≥ 8.2 Kpa. RESULTS: At baseline, the median value of LSM was 14.1 kPa for advanced fibrosis/cirrhosis and 6.9 kPa for non-advanced fibrosis. LSM was performed at 24 months from the start of therapy. The treated patients (68% received Entecavir and 32% Tenofovir) showed a decrease in liver stiffness measurement of 1.5 kPa (p < 0.001) in non-advanced fibrosis and of 6 kPa (p < 0.001) in advanced fibrosis/cirrhosis. In the patients not undergoing antiviral treatment, no statistically significant change of the LSM was observed (p = 0.26). A logistic binary regression model showed that the only independent factor associated with a significant change in the LSM was the liver stiffness value at baseline (odd ratio 2.855; 95% CI 1.456-5.788; (p = 0.007). CONCLUSION: Long-term antiviral therapy induced a significant reduction of liver stiffness measurement and this result may be related to the reduction of liver fibrosis.

Adherence to Barcelona Clinic Liver Cancer guidelines in field practice: Results of Progetto Epatocarcinoma Campania.

BACKGROUND AND AIM: The Barcelona Clinic Liver Cancer (BCLC) algorithm is the standard system for clinical management of hepatocellular carcinoma (HCC). Data on adherence to this therapeutic paradigm are scarce. This field practice study aimed to provide a description of HCC cirrhotic patients in Southern Italy, to evaluate the adherence to BCLC guidelines and its impact on patients' survival. METHODS: We analyzed the region-wide Italian database of Progetto Epatocarcinoma Campania, which includes data of HCC cirrhotic patients, prospectively collected from January 2013 to December 2015 in 16 regional centers. RESULTS: Overall, 1008 HCC patients were enrolled: 70.6% patients received therapies recommended by BCLC algorithm, while 29.4% underwent different treatments. Among patients who were treated in adherence to guidelines, a higher rate of diagnosis on surveillance programs, better liver function, lower rate of alpha-fetoprotein > 200 ng/mL, more early-stage and monofocal HCC, lower frequency of nodules > 5 cm, portal vein thrombosis and metastases were observed. The overall survival was evaluated according to HCC stage and no differences between groups and patients managed differently were found. The multivariate analysis showed that non-adherence to treatment guidelines was independently associated to the BCLC stage B, Child-Pugh classes B and C, and the presence of neoplastic thrombosis and metastases. CONCLUSION: Adherence to BCLC algorithm in field practice was high in early and end-stage HCC patients, but it was poor in intermediate and advanced patients.

The Italian compassionate use of sofosbuvir observational cohort study for the treatment of recurrent hepatitis C: clinical and virological outcomes.

Direct antivirals are available for treating recurrent hepatitis C (RHC). This study reported outcomes of 424 patients with METAVIR F3-F4 RHC who were treated for 24 weeks with sofosbuvir/ribavirin and followed for 12 weeks within the Italian sofosbuvir compassionate use program. In 55 patients, daclatasvir or simeprevir were added. Child-Pugh class and model of end stage liver disease (MELD) scores were evaluated at baseline and 36 weeks after the start of therapy. The sustained viral response (SVR) was 86.7% (316/365) in patients who received sofosbuvir/ribavirin and 98.3% (58/59) in patients who received a second antiviral (P < 0.01). In patients treated with sofosbuvir/ribavirin, a significant difference in SVR was observed between patients diagnosed with METAVIR F4 (211/250; 84.4%), METAVIR F3 (95/105; 90.5%) and fibrosing cholestatic hepatitis (10/10; 100%) (P = 0.049). A significant association was found between patients who worsened from Child-Pugh class A and who experienced viral relapse (4/26 vs. 8/189, P = 0.02). In patients with a baseline MELD score <15, a significant association was found between maintaining a final MELD score <15 and the achievement of SVR (187/219 vs. 6/10, P = 0.031). This real-world study indicates that sofosbuvir/ribavirin treatment for 24 weeks was effective, and the achievement of SVR was associated with a reduced probability of developing worsening liver function.

Development of a risk score to predict portal vein tumor thrombosis in patients with hepatocellular carcinoma.

BACKGROUND: Portal vein tumor thrombosis (PVTT) is a common complication of hepatocellular carcinoma and is one of the most negative prognostic factors. The management of patients with PVTT is challenging. The aim of the study was to develop a score predictive of tumor thrombosis. METHODS: Data from a large cohort of 2243 hepatocellular carcinoma patients (all stages) recorded in the Progetto Epatocarcinoma Campania (January 2013-April 2021) database were analyzed. To construct the score, univariate generalized estimated equation models, the bootstrap approach for internal validation, and a regression coefficient-based scoring system were used. RESULTS: PVTT (any location) was found in 14.4% of cases and was related to shorter survival. Males, younger patients, and symptomatic cases were more prevalent among the PVTT group. At multivariate analysis, size ≥5 cm, massive or infiltrative hepatocellular carcinoma growth, and alpha-fetoprotein ≥400 ng/mL were significantly associated with PVTT. A risk prediction score of PVTT based on eight variables was developed. Using a continuous score, the risk was associated with an odds ratio (OR) of 1.30 (1.27-1.34; P  < 0.001). Considering a dichotomous score >8 versus a score ≤8 the OR for PVTT was 11.33 (8.55-15.00; P  < 0.001). CONCLUSION: The risk score for PVTT might be useful for clinicians to optimize hepatocellular carcinoma management by picking out patients with more aggressive cancers and higher mortality rates. Prospective validation of the score is needed before its application in daily clinical practice.

Survival after locoregional treatments for hepatocellular carcinoma: a cohort study in real-world patients.

Evidence of relative effectiveness of local treatments for hepatocellular carcinoma (HCC) is scanty. We investigated, in a retrospective cohort study, whether surgical resection, radiofrequency ablation (RFA), percutaneous ethanol injection (PEI), and transarterial embolization with (TACE) or without (TAE) chemotherapy resulted in different survival in clinical practice. All patients first diagnosed with HCC and treated with any locoregional therapy from 1998 to 2002 in twelve Italian hospitals were eligible. Overall survival (OS) was the unique endpoint. Three main comparisons were planned: RFA versus PEI, surgical resection versus RFA/PEI (combined), TACE/TAE versus RFA/PEI (combined). Propensity score method was used to minimize bias related to non random treatment assignment. Overall 425 subjects were analyzed, with 385 (91%) deaths after a median followup of 7.7 years. OS did not significantly differ between RFA and PEI (HR 1.11, 95% CI 0.79-1.57), between surgery and RFA/PEI (HR 0.95, 95% CI 0.64-1.41) and between TACE/TAE and RFA/PEI (HR 0.88, 95% CI 0.66-1.17). 5-year OS probabilities were 0.14 for RFA, 0.18 for PEI, 0.27 for surgery, and 0.15 for TACE/TAE. No locoregional treatment for HCC was found to be more effective than the comparator. Adequately powered randomized clinical trials are still needed to definitely assess relative effectiveness of locoregional HCC treatment.

Pre-transplant diabetes predicts atherosclerotic vascular events and cardiovascular mortality in liver transplant recipients: a long-term follow-up study.

Background Early after surgery, liver transplant (LT) recipients often develop weight gain. Metabolic disorders and cardiovascular disease represent main drivers of morbidity and mortality. Our aim was to identify predictors of atherosclerotic vascular events (AVE) and to assess the impact of AVE on the long-term outcome. Methods We retrospectively analyzed data from patients transplanted between 2000 and 2005 and followed-up in five Italian transplant clinics. Cox Regression analysis was performed to identify predictors of AVE, global mortality, and cardiovascular mortality. Survival analysis was performed using the Kaplan-Meier method. Results We analyzed data from 367 subjects during a median follow-up of 14 years. Thirty-seven post-LT AVE were registered. Patients with AVE more frequently showed pre-LT diabetes mellitus (DM) (48.6 vs 13.9%, p=0.000). In the post-LT period, patients with AVE satisfied criteria of metabolic syndrome in 83.8% vs. 36.7% of subjects without AVE (p=0.000). At multivariate analysis, pre-LT DM independently predicted AVE (HR 2.250, CI 4.848-10.440, p=0.038). Moreover, both pre-LT DM and AVE strongly predicted cardiovascular mortality (HR 5.418, CI 1.060-29.183, p=0.049, and HR 86.097, CI 9.510-779.480, p=0.000, respectively). Conclusions Pre-LT DM is the main risk factor for post-LT AVE. Pre-LT DM and post-LT AVE are strong, long-term predictors of cardiovascular mortality. Patients with pre-LT DM should obtain a personalized follow-up for prevention or early diagnosis of AVE.

Toward Zero Hepatitis C Virus-Related Mortality as a Prerequisite for the Release of Resources in a Center for Follow-up of Liver Transplant.

Taking charge of a liver transplanted (LT) patient implies not only to follow up the transplanted organ (eg, immunosuppression and cancer risk) but also to deal with the prevailing patient's active problems. The recurrence of hepatitis C on the graft has historically been one of the main active problems to be addressed, leading to 30% to 40% mortality per se in these patients and has involved many resources in the hepatological centers responsible for the follow-up. We verified how much the availability of the new drugs with direct-acting antiviral agents (DAAs) against hepatitis C virus (HCV) has impacted the mortality within the assisted population, changing its characteristics and addressing new clinical issues in the LT-patients. We performed a retrospective comparison between 230 LT patients followed up during pre-DAA era (group 1, with 88 HCV RNA-positive) and 244 patients observed from 2014 onward when DAAs became available (group 2, with 79 HCV RNA-positive). Fifty-two antiviral therapies were performed in group 1 with 18 sustained virologic response (SVR) (35%) and 53 treatments, of which 37 were retreatments, in group 2 with 51 SVR (96%), P = .0001. Deaths for HCV-related causes were 19 of 33 (57%) in group 1 and 7 of 24 (24%) in group 2, P = .01. The Kaplan-Meier showed a dramatic reduction in excess mortality in HCV-LT patients after the availability of DAAs. These results suggest that HCV is no longer the main active problem of follow-up in liver transplants, therefore the resources can be relocated to take care of other clinical aspects.

Daclatasvir-based regimens in HCV cirrhosis: experience from the Italian early access program.

We reported the efficacy and safety data for daclatasvir (DCV)-based all-oral antiviral therapy in patients treated in the Italian compassionate-use program. 275 patients were included (202 male-73.5%, mean age: 57.4 years, 62 HIV-coinfected, 94 with recurrence of hepatitis C post-OLT). Forty-nine patients (17.8%) had Child-Pugh B, Genotype(G) distribution was: G1a:72 patients (26.2%), G1b:137 (49.8%); G3:40 (14.5%) and G4:26 (9.5%). Patients received DCV with sofosbuvir(SOF) (n = 221, 129 with ribavirin(RBV) or with simeprevir (SMV) or asunaprevir (ASU) (n = 54, 19 with RBV) for up to 24 weeks. Logistic regression was used to identify baseline characteristics associated with sustained virological response at week 12 post-treatment (SVR12). Liver function changes between baseline and follow up were assessed in 228 patients. 240 patients achieved SVR12 (87.3%), post transplant and HIV co-infected patients were equally distributed among SVR and no SVR (35% vs 34.3%; p = 0.56 and 24.2% vs 11.4%, p = 0.13, respectively). SVR rate was significantly higher with the combination DCV + SOF compared with DCV + SIM or ASU (93.2% vs 63.0%, p < 0.0001). Bilirubin value (OR: 0.69, CI95%: 0.54-0.87, p = 0.002) and regimen containing SOF (OR: 9.99, CI95%: 4.09-24.40; p < 0.001) were independently related with SVR. Mean albumin and bilirubin values significantly improved between baseline and follow-up week 12. DCV-based antiviral therapy was well tolerated and resulted in a high SVR when combined with SOF either in pre-transplant and in OLT patients and in "difficult to treat" HCV genotypes. Regimens containing DCV in combination with NS3 protease inhibitors obtained suboptimal results.

Virological pattern in plasma, peripheral blood mononuclear cells and liver tissue and clinical outcome in chronic hepatitis B and C virus coinfection.

BACKGROUND: We aim to evaluate in chronic hepatitis B virus-hepatitis C virus (HBV-HCV) coinfection the interplay of these viruses in liver tissue, peripheral blood mononuclear cells (PBMC), and plasma and to analyze the effect on disease course and response to treatment. METHODS: We enrolled 19 patients with chronic HBV-HCV coinfection, 20 with chronic HCV and 20 with chronic HBV infection at their first liver biopsy, all were naive for antiviral therapy. The patients' plasma, PBMC and liver biopsy samples were tested for HBV DNA and/or HCV RNA by real-time PCR, according to the presence/absence of hepatitis B surface antigen and antibodies against HCV in the serum. RESULTS: Contemporary presence of HBV DNA and HCV RNA was rare in plasma (5.3% of cases) and PBMC (10.6%), but frequent in liver tissue (52.6%). Of 10 cases circulating only HCV RNA and treated with pegylated interferon (PEG-IFN) plus ribavirin for 12 months, two showed a sustained response, and eight cleared HCV RNA but became HBV-DNA-positive in plasma; these eight had detectable HBV DNA in liver at baseline. One patient, who was plasma HBV-DNA-positive/HCV-RNA-negative at baseline, showed a sustained response after 18 months of PEG-IFN treatment; another, who was plasma HBV-DNA/HCV-RNA-positive at baseline, cleared only HCV RNA during 12 months of PEG-IFN plus ribavirin treatment. Seven cases remained untreated. CONCLUSION: Despite a reciprocal inhibition in plasma, HBV and HCV frequently coexist in liver tissue, a condition to be taken into consideration when deciding therapy.

Diagnosis and clinical impact of occult hepatitis B infection in patients with biopsy proven chronic hepatitis C: a multicenter study.

Occult hepatitis B virus (HBV) infection in patients with chronic hepatitis C has been found associated with severe liver damage, low response to interferon treatment and increased risk of developing HCC. However, doubts remain on its clinical impact and the sensitivity and specificity of its detection. HBV-DNA was sought by PCR in plasma, peripheral blood mononuclear cells (PBMCs) and liver compartments of 89 patients with biopsy proven chronic hepatitis C, using sets of primers for core ("c"), surface ("s"), and x ("x") regions of HBV genome. Occult HBV infection was defined by the presence of HBV-DNA in at least two different PCRs in at least one compartment. Occult HBV infection was detected in 37 (41.6%) of the 89 patients investigated. It was more frequent (80.8%) in 26 anti- HBs negative/anti-HBc positive patients than in 18 anti-HBs/anti-HBc positive (61.1%, P < 0.01) and 45 anti-HBs/anti-HBc negative (11.1%, P < 0.0001), and more frequently in liver (91.9%) than in PBMCs (62.2%) and plasma (32.4%). No association was found between occult HBV infection and the degree of liver necroinflammation and fibrosis. However, considering the 52 patients without occult HBV infection, 51.4% of 35 patients with genotype 1 and 5.9% of 17 with genotype non-1 showed severe fibrosis (P = 0.003); patients with occult HBV infection did not show such difference. Instead of seeking occult HBV infection in patients with chronic hepatitis C, both anti-HBs negative/anti-HBc positive and anti-HBs positive/anti-HBc positive, in plasma alone, more reliable information can also be obtained from the liver tissue and PBMCs.

Prevalent use of combined prophylaxis of hepatitis B after liver transplantation in Italy: results of a national survey in a large cohort.

BACKGROUND: Prophylaxis of hepatitis B after liver transplantation with antiviral(s) and immunoglobulins efficiently protect the majority of recipients; however recent experiences suggest a decline of HBsAg-positive candidates and the use of hepatitis B Immunoglobulin-free schedules. METHODS: This national survey evaluated the epidemiology and clinical results of hepatitis B prophylaxis among 10,365 liver transplants performed in 25 years in 13 Italian centers. RESULTS: With a percentage of 22, 2260 procedures were performed in HBsAg-positive recipients and 714 out of 1080 anti-HBc-positive grafts were used in HBsAg-negative recipients; a total of 2974 patients (29%) were considered at risk of hepatitis B after liver transplantation. Similar rates (18% of HBsAg-positive candidates and 15% of anti-HBc-positive grafts) were registered in the last collected year. Combined prophylaxis with Hepatitis B Immunoglobulins remained prevalent among centers and was effective in 96% of HBsAg-positive recipients and in 94% of HBsAg-negative recipients of anti-HBc-positive grafts. CONCLUSIONS: Data from this survey confirm: the excellent results of combined prophylaxis; the past and persistent use of Hepatitis B Immunoglobulin-on and only rare -off prophylactic regimens, in contrast with the newest reports; the increasing use of anti-HBc-positive grafts; the past and present high prevalence of HBsAg-positive recipients, due to an increase in candidates with either hepatocellular carcinoma and Hepatitis Delta Virus coinfection in the last years.

Serial Liver Stiffness Measurements and Monitoring of Liver-Transplanted Patients in a Real-Life Clinical Practice.

BACKGROUND: Liver transplanted patients need close surveillance for early signs of graft disease. OBJECTIVES: Transient elastography can safely be repeated over time, offering serial liver stiffness measurement values. Serial stiffness measurements were compared to single baseline stiffness measurements in predicting the appearance of liver-related clinical events and guiding subsequent clinical decisions. METHODS: One hundred and sixty liver transplanted patients were observed for three years in our real-life practice. RESULTS: Liver stiffness measurements were stable in 75% of patients, decreased in 4% of patients, and increased in 21% of patients. The pattern of increased stiffness measurements was associated with both HCV-RNA positive status and the presence of an active biliary complication of liver transplantation and was more predictive of a clinically significant event resulting from any disease of the transplanted liver when compared to a stable pattern or to a single liver stiffness measurement. The procedures that were consequently performed were often diagnostic for unexpected situations, both in HCV-RNA positive and HCV-RNA negative patients. CONCLUSIONS: The pattern of longitudinally increased liver stiffness measurements efficiently supported clinical decisions for individualized management strategies. Repeated transient elastography in real-life clinical practice appears to have a practical role in monitoring liver transplanted patients.

Triple (interferon, ribavirin, amantadine) versus double (interferon, ribavirin) re-therapy for interferon relapser genotype 1b HCV chronic active hepatitis patients.

BACKGROUND: Retreatment for 6 months with the association ribavirin-interferon of HCV-related chronic active hepatitis relapser patients has high probability of failure, mostly in those with genotype 1b. We evaluated the efficacy of extending the therapy from 6 to 12 months without or with the addition of amantadine. METHODS: Forty-nine genotype 1b relapser patients were treated with 3 MU of IFN-alpha2b three times per week and ribavirin 1000-1200 mg daily (double therapy). Twenty-four patients, who did not respond after 6 months of treatment, were randomized to continue for further 6 months either with the same schedule or with also the addition of amantadine 200 mg daily (triple therapy). RESULTS: A sustained virological response was observed in 15/37 subjects (41%) treated for 12 months of double therapy. In the arm of the study evaluating amantadine, end of treatment virologic response was observed in 0/12 patients of double therapy group and in 4/12 of triple therapy (P=0.09). After 6 months of follow-up, a sustained virologic response (SVR) was observed in two patients treated with the triple therapy. CONCLUSIONS: This study confirms poor results of retreatment (even if 12 months double or triple therapy) in relapser patients with HCV hepatitis, genotype 1b. No gain was obtained in prolonging from 6 to 12 months the standard double therapy, while triple therapy with amantadine as an additional regimen for this difficult subgroup of patients showed some cases of SVRs: amantadine addition deserves to be evaluated in larger trials.

Sorafenib plus octreotide is an effective and safe treatment in advanced hepatocellular carcinoma: multicenter phase II So.LAR. study.

PURPOSE: Advanced hepatocellular carcinoma (HCC) not eligible for local therapies has limited chances of cure. Sorafenib is a multikinase inhibitor with proven activity in advanced HCC. Octreotide is used in this setting with conflicting results. Treatment with sorafenib and long-acting octreotide was tested in advanced HCC to evaluate safety and activity. METHODS: Fifty patients with advanced HCC, Child-Pugh A or B, received sorafenib at a dosage of 800 mg/day for 28 days with a following week of rest and long-acting octreotide at a dose of 40 mg, administered every 28 days. RESULTS: All patients were assessable for safety and efficacy. Sixteen patients out of 50 (34%) were naïve from other therapies, while all the others were previously treated with local and/or systemic treatments. We achieved 5 partial responses (10%), 33 stable diseases (66%) and 12 progressions of disease (24%). Median time to progression was 7.0 months (95% CI, 3.0-10.9 months), and median overall survival was 12 months (95% CI, 6.3-17.4 months). Treatment was well tolerated. Diarrhoea (6%) and hypertension (4%) were the most frequent grade 3 toxicities. CONCLUSIONS: Our data suggest that the combination between sorafenib and long-acting octreotide is active and well tolerated in patients with advanced HCC and could represent another efficacious chance for the management of this population.
