RESUMO

BACKGROUND AND AIMS: Mixed cryoglobulinemia is the most common HCV extrahepatic manifestation. We aimed to prospectively evaluate the cryoglobulinemic vasculitis (CV) clinical profile after a sustained virologic response (SVR) over a medium-term to long-term period. APPROACH AND RESULTS: Direct-acting antiviral-treated cryoglobulinemic patients, consecutively enrolled in the multicentric Italian Platform for the Study of Viral Hepatitis Therapy cohort, were prospectively evaluated. Cumulative incidence Kaplan-Meier curves were reported for response, clinical deterioration, relapse and relapse-free survival rates. Cox regression analysis evaluated factors associated with different outcomes. A clinical response was reported in at least one follow-up point for 373 of 423 (88%) patients with CV who achieved SVR. Clinical response increased over time with a 76% improvement rate at month 12 after the end of treatment. A full complete response (FCR) was reached by 164 (38.8%) patients in at least one follow-up point. CV clinical response fluctuated, with some deterioration of the initial response in 49.6% of patients (median time of deterioration, 19 months). In patients who achieved FCR and had an available follow-up (137 patients) a relapse was observed in 13% and it was transient in 66.7% of patients. The rate of patients without any deterioration was 58% and 41% at 12 and 24 months, respectively. After achieving SVR, a clinical nonresponse was associated with older age and renal involvement; a clinical deterioration/relapse was associated with high pretreatment rheumatoid factor values, and FCR was inversely associated with age, neuropathy, and high cryocrit levels. CONCLUSION: In patients with CV, HCV eradication may not correspond to a persistent clinical improvement, and clinical response may fluctuate. This implies an attentive approach to post-SVR evaluation through prognostic factors and tailored treatment.

RESUMO

The reliability and safety of front-line ultrasonography guided core needle biopsy (UG-CNB) performed with specific uniform approach have never been evaluated in a large series of patients with lymphadenopathies suspected of lymphoma. The aim of this study was to assess the overall accuracy of UG-CNB in the lymph node histological diagnosis, using a standard reference based on pathologist consensus, molecular biology, and/or surgery. We retrospectively checked the findings concerning the application of lymph node UG-CNB from four Italian clinical units that routinely utilized 16-gauge diameter modified Menghini needle under power-Doppler ultrasonographic guidance. A data schedule was sent to all centers to investigate the information regarding techniques, results, and complications of lymph node UG-CNB in untreated patients over a 12-year period. Overall, 1000 (superficial target, n = 750; deep-seated target, n = 250) biopsies have been evaluated in 1000 patients; other 48 biopsies (4.5%), screened in the same period, were excluded because inadequate for a confident histological diagnosis. Most patients were suffering from lymphomas (aggressive B-cell non-Hodgkin lymphoma [aBc-NHL], 309 cases; indolent B-cell [iBc]-NHL, 279 cases; Hodgkin lymphoma [HL], 212 cases; and nodal peripheral T-cell [NPTC]-NHL, 30 cases) and 100 cases from metastatic carcinoma; 70 patients had non-malignant disorders. The majority of CNB results met at least one criterion of the composite reference standard. The overall accuracy of the micro-histological sampling was 97% (95% confidence interval: 95%-98%) for the series. The sensitivity of UG-CNB for the detection of aBc-NHL was 100%, for iBc-NHL 95%, for HL 93%, and for NPTC-NHL 90%, with an overall false negative rate of 3.3%. The complication rate was low (6% for all complications); no patient suffered from biopsy-related complications of grade >2 according to the Common Terminology Criteria for Adverse Events. Lymph node UG-CNB as mini-invasive diagnostic procedure is effective with minimal risk for the patient.

RESUMO

BACKGROUND: Glecaprevir and Pibrentasvir (G/P) determine high rates of sustained virological response (SVR) with optimal safety profile in patients with chronic hepatitis C virus (HCV) infection. The efficacy and safety of G/P in Caucasian patients aged 75 years and older have not been widely analysed. METHODS: This is a retrospective multicentre real-world study enrolling all consecutive patients 75 years and older who received G/P between October 2017 and January 2022 at five referral centres in Italy. SVR was analysed by intention-to-treat (ITT) and per-protocol analyses (PP). RESULTS: A total of 570 patients met the inclusion criteria and were analysed: mean age was 80 (75-97) years, 356 (62%) were females, 52% (298/570) had HCV-1, 44% (252/570) had HCV-2 and 137 (24%) patients had liver cirrhosis. Four hundred and sixty-three (81%) patients were taking at least one concomitant drug, with 144 (25%) taking ≥5 concomitant drugs. G/P was given for 8 weeks in 488 patients (86%). During treatment, 48 patients (8%) reported side effects, with 10 (2%) patients discontinuing treatment prematurely. Two patients developed treatment-unrelated serious adverse events. Overall, the SVR rate was 97.9% (558/570) by ITT analysis and 99.6% (558/560) by PP analysis. SVR rates remained consistently high among subgroup analysis stratified by genotype, treatment duration, fibrosis stage and concomitant medications. CONCLUSIONS: Treatment with G/P achieved 97.9% SVR rates in HCV patients older than 75 years of age. Safety was optimal with only 2% of patients discontinuing early.

RESUMO

INTRODUCTION: Non-Alcoholic Fatty Liver Disease encompasses a spectrum of diseases ranging from simple steatosis to steatohepatitis (or NASH), up to cirrhosis and hepatocellular carcinoma (HCC). The challenge is to recognize the more severe and/or progressive pathology. A reliable non-invasive method does not exist. Untargeted metabolomics is a novel method to discover biomarkers and give insights on diseases pathophysiology. OBJECTIVES: We applied metabolomics to understand if simple steatosis, steatohepatitis and cirrhosis in NAFLD patients have peculiar metabolites profiles that can differentiate them among each-others and from controls. METHODS: Metabolomics signatures were obtained from 307 subjects from two separated enrollments. The first collected samples from 69 controls and 144 patients (78 steatosis, 23 NASH, 15 NASH-cirrhosis, 8 HCV-cirrhosis, 20 cryptogenic cirrhosis). The second, used as validation-set, enrolled 44 controls and 50 patients (34 steatosis, 10 NASH and 6 NASH-cirrhosis).The "Partial-Least-Square Discriminant-Analysis"(PLS-DA) was used to reveal class separation in metabolomics profiles between patients and controls and among each class of patients, and to reveal the metabolites contributing to class differentiation. RESULTS: Several metabolites were selected as relevant, in particular:Glycocholic acid, Taurocholic acid, Phenylalanine, branched-chain amino-acids increased at the increase of the severity of the disease from steatosis to NASH, NASH-cirrhosis, while glutathione decreased (p < 0.001 for each). Moreover, an ensemble machine learning (EML) model was built (comprehending 10 different mathematical models) to verify diagnostic performance, showing an accuracy > 80% in NAFLD clinical stages prediction. CONCLUSIONS: Metabolomics profiles of NAFLD patients could be a useful tool to non-invasively diagnose NAFLD and discriminate among the various stages of the disease, giving insights into its pathophysiology.

RESUMO

BACKGROUND & AIMS: Glecaprevir/pibrentasvir is approved for treating adults infected with HCV genotypes 1-6. In clinical trials, glecaprevir/pibrentasvir was associated with high rates of sustained virologic response at post-treatment week 12 (SVR12) and was well tolerated. A systematic review and meta-analysis of the real-world effectiveness and safety of glecaprevir/pibrentasvir were undertaken. METHODS: Real-world studies reporting SVR12 in adults with HCV infection (n ≥20) treated with glecaprevir/pibrentasvir were identified in journal publications from January 1, 2017, to February 25, 2019, and congress presentations through April 14, 2019. Random-effects meta-analysis was used to determine SVR12 rates using data from ≥2 cohorts; intention-to-treat (ITT) analyses included patients treated with glecaprevir/pibrentasvir who had SVR12 data available, discontinued early, or were lost to follow-up; modified ITT (mITT) analyses excluded those with non-virologic failure. Naïve pooling was used to calculate adverse event (AE) rates. RESULTS: Overall, 12,531 adults were treated with glecaprevir/pibrentasvir (18 cohorts). Of patients with post-treatment week 12 data, SVR12 rates were 96.7% (95% CI 95.4-98.1) in the ITT population (n = 8,583, 15 cohorts) and 98.1% (95% CI 97.1-99.2) in the mITT population (n = 7,001, 14 cohorts). SVR12 rates were ≥95% across subgroups (HCV genotype, cirrhosis status, treatment history, treatment duration, on-label treatment, and subgroups of interest). AEs were reported in 17.7% (1,271/7,199) of patients (8 cohorts). Serious AEs were reported in 1.0% (55/5,522) of patients (6 cohorts). The most frequent AEs were pruritus, fatigue, and headache. AE-related treatment discontinuations were reported in 0.6% (33/5,595) of patients (6 cohorts). CONCLUSIONS: Consistent with clinical trials, real-world evidence indicates that glecaprevir/pibrentasvir is a well-tolerated and highly effective pangenotypic treatment for a broad range of HCV-infected patients. LAY SUMMARY: It is important to assess treatments for hepatitis C virus (HCV) in the real world, as patient populations tend to be more diverse and potentially less adherent to treatment compared to those in clinical trials. Results from 18 studies performed in real-world clinics were pooled and analyzed to investigate the effectiveness and safety of a direct-acting antiviral combination (glecaprevir/pibrentasvir) in routine clinical practice. This analysis showed that glecaprevir/pibrentasvir is highly effective and well tolerated across all HCV genotypes and patient groups studied. It also showed that results seen in the real world are similar to the results seen in clinical trials, even in patients historically considered more challenging to treat.

RESUMO

BACKGROUND: Chronic hepatitis C virus (HCV) infection is more prevalent among patients who have chronic kidney disease than among those who do not have the disease. Patients with chronic kidney disease who also have HCV infection are at higher risk for progression to end-stage renal disease than those who have chronic kidney disease without HCV infection. Patients with both HCV infection and advanced chronic kidney disease have limited treatment options. METHODS: We conducted a multicenter, open-label, phase 3 trial to evaluate the efficacy and safety of treatment with the combination of the NS3/4A protease inhibitor glecaprevir and the NS5A inhibitor pibrentasvir for 12 weeks in adults who had HCV genotype 1, 2, 3, 4, 5, or 6 infection and also had compensated liver disease (with or without cirrhosis) with severe renal impairment, dependence on dialysis, or both. Patients had stage 4 or 5 chronic kidney disease and either had received no previous treatment for HCV infection or had received previous treatment with interferon or pegylated interferon, ribavirin, sofosbuvir, or a combination of these medications. The primary end point was a sustained virologic response 12 weeks after the end of treatment. RESULTS: Among the 104 patients enrolled in the trial, 52% had genotype 1 infection, 16% had genotype 2 infection, 11% had genotype 3 infection, 19% had genotype 4 infection, and 2% had genotype 5 or 6 infection. The sustained virologic response rate was 98% (102 of 104 patients; 95% confidence interval, 95 to 100). No patients had virologic failure during treatment, and no patients had a virologic relapse after the end of treatment. Adverse events that were reported in at least 10% of the patients were pruritus, fatigue, and nausea. Serious adverse events were reported in 24% of the patients. Four patients discontinued the trial treatment prematurely because of adverse events; three of these patients had a sustained virologic response. CONCLUSIONS: Treatment with glecaprevir and pibrentasvir for 12 weeks resulted in a high rate of sustained virologic response in patients with stage 4 or 5 chronic kidney disease and HCV infection.

RESUMO

BACKGROUND AND AIMS: Chronic hepatitis C virus (HCV) infection increases the risk of incident chronic kidney disease (CKD) and progression to end-stage renal disease (ESRD). Previously available direct-acting antiviral regimens are not approved for patients with advanced CKD across all HCV genotypes. METHODS: EXPEDITION-5 is a phase 3 study to evaluate efficacy and safety of the fixed-dose combination of glecaprevir and pibrentasvir (G/P) for chronic HCV infection (genotype 1 through 6) in adults without cirrhosis or with compensated cirrhosis and with stage 3b, 4 or 5 CKD. Patients received approved duration of G/P according to HCV genotype, cirrhosis status and prior HCV treatment experience. The primary efficacy endpoint was percentage of patients with sustained virologic response at 12 weeks post-treatment (SVR12). RESULTS: Among the 101 patients enrolled in the study, 24% had predialysis CKD and 76% were on dialysis. Eighty-four patients were treated with G/P for 8 weeks, 13 patients for 12 weeks and four patients for 16 weeks. Fifty-five per cent of patients had genotype 1, 27% had genotype 2, 15% had genotype 3 and 4% had genotype 4, and none had genotype 5 or 6 infection. The SVR12 rate was 97% (98/101, 95% confidence interval, 91.6-99.0). No patients experienced virologic failure. Adverse events (AEs) reported in at least 5% of the patients were pruritus, bronchitis, hypertension and generalized pruritus. Serious AEs were reported in 12% of patients; none related to study drug. CONCLUSIONS: G/P treatment yielded high SVR12 rates irrespective of the presence of stage 3b, 4 or 5 CKD. No safety signals were detected. CLINICALTRIALS. GOV IDENTIFIER: This Phase 3 clinical trial was funded by AbbVie and registered with clinicaltrials.gov as NCT03069365 (EXPEDITION-5).

RESUMO

The association of hepatitis C virus (HCV) with non-Hodgkin's lymphoma (NHL) has been demonstrated throughout the world. The new interferon-free direct antiviral agents (DAAs) showed high efficacy and safety, and preliminary data seem to confirm their activity on low-grade NHL. The question arises as whether or not-and how-to treat the HCV-positive patients suffering from diffuse large B-cell lymphomas (DLBCLs). The aim of this observational study was to evaluate whether DAA antiviral treatment of DLBCL/HCV-infected patients in concomitance with chemotherapy is a safe and effective option. Twenty (13 males and 7 females) HCV genotype 1b-positive subjects, undergoing chemotherapy for DLBCL, were enrolled between June 2015 and December 2015. After informed consent, all patients underwent antiviral therapy (AVT) with sofosbuvir/ledipasvir and chemotherapy (14 rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone and 6 cyclophosphamide, doxorubicin, vincristine, and prednisone) for DLBCL. Complete hematological (Revised European-American Lymphoma classification, Ann Arbor, and International Prognostic Index [IPI] scores) and hepatological (viral markers, liver stiffness, and biochemical parameters) evaluations were made. A historical retrospective cohort of 101 DLBCL/HCV-positive patients not undergoing AVT was enrolled for comparison. DAA-treated and untreated patients were similar for sex distribution, IPI score, and NHL stage, and differed for age (older in treated), chemotherapy and use of AVT. Overall survival (OS) and disease-free survival (DFS) were evaluated among a 52-week of follow-up. No statistical difference was found in OS after 52 weeks (P = 0.122), whereas a statistically significant higher DFS was achieved in treated patients (P = 0.036). At the multivariate analysis, only IPI score and AVT were independently correlated with a better DFS. No differences in adverse events were reported. CONCLUSION: DAA treatment in concomitance with chemotherapy was shown to be safe and effective in influencing remission of aggressive lymphomas in HCV patients. (Hepatology 2018;67:48-55).

RESUMO

BACKGROUND AND AIMS: Direct antiviral agents have greatly improved therapeutic options for chronic hepatitis C. Indeed, former "difficult-to-treat" patients can now be treated and can achieve sustained response. Hepatitis C virus (HCV) is associated with hepatocellular carcinoma and with B-cell non-Hodgkin lymphoma (B-NHL). Other malignancies have been reported to be associated with HCV infection albeit with various grades of evidence. Antineoplastic treatment is often reduced or suspended in HCV-positive cancer patients to avoid "HCV reactivation." In this setting, antiviral therapy combined with antineoplastic protocols may improve the outcome. For this reason, we conducted a systematic review and a meta-analysis to update the association between HCV infection and non-hepatocellular malignancies, and to shed light on the effects exerted by antiviral treatment on the natural history of oncological diseases. METHODS: Relevant studies were identified by searching PUBMED, EMBASE and MEDLINE up to 1 August 2018. Pooled risk estimates were calculated with random-effects models according to PRISMA guidelines. RESULTS: A total of 58 studies were included in the analysis: 27 studies of the association between HCV and B-NHL(OR 3.36; 95% CI 2.40-4.72;P < 0.00001);13 studies of the association between sustained virological response and progression-free survival (PFS) in B-NHL patients(OR 9.34; 95% CI 4.90-17.79; P < 0.00001); 13 studies of the association between HCV and intrahepatic-cholangio-carcinoma (OR 3.95;95% CI 2.25-6.94; P < 0.00001); and 5 studies of the association between HCV infection and pancreatic adeno-carcinoma(OR 1.60; 95% CI:1.25-2.04; P = 0.0002). CONCLUSIONS: This study updates the strong association between B-NHL and HCV infection, confirms the association between HCV and non-hepatocellular tumours, and demonstrates a very strong association between viral eradication and a better outcome of HCV-positive B-NHL.

RESUMO

BACKGROUND AND AIMS: People who use drugs (PWUD) represent an active reservoir of HCV infection. The prevalence of chronic HCV infection in PWUD in Italy remains unknown because of the lack of systematic screening. Thanks to direct-acting antiviral agents (DAAs), hepatitis C can now be cured in most patients. Thus, the next challenge is to provide linkage-to-care for these patients. METHODS: In this scenario, we conducted a screening programme in PWUD attending seven Addiction Centers in Southern Italy, as well as a treatment programme in the Liver Unit of the University Hospital of Salerno. We used the OraQuick HCV antibody test to screen the PWUD (from 1 April to 30 September 2018). RESULTS: 593 subjects were consecutively enrolled in the programme; 250 (41.8%) were HCV-Ab-positive. 143 (24.1%) were aware of their infection and had been HCV-RNA-tested: 83 were positive and 60 negative. The remaining 107 subjects (18.1%) had never previously been tested and were unaware of their infection. A total of 160 (26.9%) HCV RNA-positive patients were found and offered antiviral therapy with DAAs. The sustained virological response rate was 98.5% and no adverse events were recorded. Two patients voluntarily discontinued treatment. No reinfections have been recorded to date. CONCLUSIONS: The prevalence of HCV-Ab positivity was high in the PWUDs enrolled in this study, and almost half the patients were unaware of being HCV-positive. The linkage-to-care provided was safe and effective, and no case of reinfection was recorded.

RESUMO

BACKGROUND AND AIMS: It is paramount to identify predictors of treatment failure with direct antiviral agents in 'field-practice' patients, including people who inject drugs (PWID). Data on the efficacy of glecaprevir/pibrentasvir (GLE/PIB) in a field-practice scenario are scant. The multicentre MISTRAL study enrolled 1177 patients, including PWID, to assess real-life efficacy and safety of GLE/PIB and to identify the predictive factors for this treatment. METHODS: This was a prospective, longitudinal study. The outcome variable was the rate of sustained virological response (SVR) at week 12. RESULTS: A total of 123 patients (10%) were infected from hepatitis C virus (HCV) 3. METAVIR fibrosis score was F4 in 104 subjects (9%); 118 patients (10%) were PWID. Overall, 1163/1177 (99%) patients achieved SVR. The baseline clinical factors discriminating between treatment success and treatment failure were age at treatment (P = 0.031) and creatinine level (P = 0.034). SVR rates were not influenced by gender, substance abuse, previous treatment, treatment duration, fibrosis or chronic kidney disease stage. Compared with non-substance users, the 118 PWID exhibited a significantly different genotype pattern distribution (χ2  < 0.001). A total of 40/118 (33.9%) of substance users were HCV3 compared to 83/1056 (7.9%) non-substance users. Only 6 patients (0.5%) reported a serious adverse event. CONCLUSIONS: The MISTRAL study provides evidence of GLE/PIB efficacy in a field-practice scenario in a highly epidemic HCV area in southern Italy; it unveiled significant differences in genotype distribution among the most underserved and difficult-to-treat patient subgroups including PWID.

RESUMO

Hepatitis C virus (HCV) infection is now considered a systemic disease due to the occurrence of extra-hepatic manifestations. Among these, the renal involvement is frequent. HCV infection, in fact, is strongly associated with proteinuria and chronic kidney disease (CKD) and negatively affects the prognosis of renal patients. In the last few years, availability of more specific and effective drugs against HCV has dramatically changed the clinical course of this disease. These drugs may provide further advantages in the CKD population as a whole by reducing progression of renal disease, mortality rate and by increasing the survival of graft in renal transplant recipients. The strict pathogenetic and prognostic link between HCV infection and CKD requires an ongoing relationship among the healthcare professionals involved in the treatment of both HCV infection and CKD. Therefore, Scientific Societies involved in the care of this high-risk population in Italy have organized a joint expert panel. The aim of the panel is to produce a position statement that can be used in daily clinical practice for the management of HCV infected patients across the whole spectrum of renal disease, from the conservative phase to renal replacement treatments (dialysis and transplantation). Sharing specific evidence-based expertise of different professional healthcare is the first step to obtain a common ground of knowledge on which to instate a model for multidisciplinary management of this high-risk population. Statements cover seven areas including epidemiology of CKD, HCV-induced glomerular damage, HCV-related renal risk, staging of liver disease in patients with CKD, prevention of transmission of HCV in hemodialysis units, treatment of HCV infection and management of HCV in kidney transplantation.

RESUMO

We evaluated the cost-effectiveness of two alternative direct-acting antiviral (DAA) treatment policies in a real-life cohort of hepatitis C virus-infected patients: policy 1, "universal," treat all patients, regardless of fibrosis stage; policy 2, treat only "prioritized" patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and health care system perspective, was applied to the PITER cohort (representative of Italian hepatitis C virus-infected patients in care). Specifically, 8,125 patients naive to DAA treatment, without clinical, sociodemographic, or insurance restrictions, were used to evaluate the policies' cost-effectiveness. The patients' age and fibrosis stage, assumed DAA treatment cost of €15,000/patient, and the Italian liver disease costs were used to evaluate quality-adjusted life-years (QALY) and incremental cost-effectiveness ratios (ICER) of policy 1 versus policy 2. To generalize the results, a European scenario analysis was performed, resampling the study population, using the mean European country-specific health states costs and mean treatment cost of €30,000. For the Italian base-case analysis, the cost-effective ICER obtained using policy 1 was €8,775/QALY. ICERs remained cost-effective in 94%-97% of the 10,000 probabilistic simulations. For the European treatment scenario the ICER obtained using policy 1 was €19,541.75/QALY. ICER was sensitive to variations in DAA costs, in the utility value of patients in fibrosis stages F0-F3 post-sustained virological response, and in the transition probabilities from F0 to F3. The ICERs decrease with decreasing DAA prices, becoming cost-saving for the base price (€15,000) discounts of at least 75% applied in patients with F0-F2 fibrosis. CONCLUSION: Extending hepatitis C virus treatment to patients in any fibrosis stage improves health outcomes and is cost-effective; cost-effectiveness significantly increases when lowering treatment prices in early fibrosis stages.

RESUMO

BACKGROUND & AIMS: Advances in direct-acting antiviral treatment of HCV have reinvigorated public health initiatives aimed at identifying affected individuals. We evaluated the possible impact of only diagnosed and linked-to-care individuals on overall HCV burden estimates and identified a possible strategy to achieve the WHO targets by 2030. METHODS: Using a modelling approach grounded in Italian real-life data of diagnosed and treated patients, different linkage-to-care scenarios were built to evaluate potential strategies in achieving the HCV elimination goals. RESULTS: Under the 40% linked-to-care scenario, viraemic burden would decline (60%); however, eligible patients to treat will be depleted by 2025. Increased case finding through a targeted screening strategy in 1948-1978 birth cohorts could supplement the pool of diagnosed patients by finding 75% of F0-F3 cases. Under the 60% linked-to-care scenario, viraemic infections would decline by 70% by 2030 but the patients eligible for treatment will run out by 2028. If treatment is to be maintained, a screening strategy focusing on 1958-1978 birth cohorts could capture 55% of F0-F3 individuals. Under the 80% linked-to-care scenario, screening limited in 1968-1978 birth cohorts could sustain treatment at levels required to achieve the HCV elimination goals. CONCLUSION: In Italy, which is an HCV endemic country, the eligible pool of patients to treat will run out between 2025 and 2028. To maintain the treatment rate and achieve the HCV elimination goals, increased case finding in targeted, high prevalence groups is required.

RESUMO

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.

RESUMO

A 20-year-old male affected by transfusion-dependent ß-thalassemia (ß-thal), was prescribed intensive chelation therapy with deferoxamine (DFO) and deferiprone (DFP) because of severe hepatic and cardiac iron overload and ß-blocker and warfarin to manage a previous event of atrial fibrillation (AFib) and heart failure. After a few months, he developed critical liver failure, renal tubulopathy and severe electrolyte imbalance. Laboratory and instrumental evaluations were performed to carry out differential diagnosis of acute liver failure and an exclusion diagnosis of drug induced liver injury (DILI) was made. The cholestatic pattern suggested warfarin as the main causative agent and polypharmacy, liver iron overload and heart failure as aggravating factors. Warfarin is a drug commonly prescribed in thalassemia patients who often need polypharmacy for the management of anemia- and iron-related complications. Strict monitoring and multidisciplinary approaches are mandatory to avoid preventable mortality in this fragile population.

RESUMO

BACKGROUND & AIMS: Assessment of long-term outcome is required in hepatitis C virus (HCV)-infected patients with cirrhosis, who have been successfully treated for Barcelona Clinic Liver Cancer (BCLC) stage A hepatocellular carcinoma (HCC). However, problems arise due to the lack of models accounting for early changes during follow-up. The aim of this study was to estimate the impact of early events (HCC recurrence or hepatic decompensation within 12months of complete radiological response) on 5-year overall survival (OS) in a large cohort of patients with HCV and cirrhosis, successfully treated HCC. METHODS: A total of 328 consecutive Caucasian patients with HCV-related cirrhosis and BCLC stage 0/A HCC who had complete radiological response after curative resection or thermal ablation were prospectively recruited to this study. Primary endpoint of the study was 5-year OS. Independent baseline and time-dependent predictors of 5-year OS were identified by Cox model. RESULTS: The observed 5-year survival rate was 44%. The observed HCC early recurrence and early hepatic decompensation rate were 21% and 10%, respectively. Early hepatic decompensation (Hazard Ratio [HR] 7.52; 95% confidence intervals (CI): 1.23-13.48) and HCC early recurrence as time-dependent covariates (HR 2.50; 95%CI: 1.23-5.05), presence of esophageal varices at baseline (HR 1.66; 95% CI: 1.02-2.70) and age (HR 1.04; 95% CI: 1.02-1.07) were significantly associated with the 5-year OS. CONCLUSION: Survival in HCV-infected patients with cirrhosis and successfully treated HCC is influenced by early hepatic decompensation. Our study indirectly suggests that direct-acting antiviral agents could improve OS of HCC patients through long-term preservation of liver function, resulting in a lower cirrhosis-related mortality and a greater change of receiving curative treatments. LAY SUMMARY: Survival in hepatitis C virus (HCV) infected patients with cirrhosis and successfully treated hepatocellular carcinoma (HCC), is mainly influenced by early hepatic decompensation. HCV eradication after treatment with new direct-acting antiviral agents could improve overall survival of HCC patients through long-term preservation of liver function.
