BACKGROUND & AIMS Patients with advanced liver disease often undergo invasive procedures, so the combination of thrombocytopenia, coagulopathy, and bleeding should be carefully assessed. We evaluated the prevalence of thrombocytopenia in a series of patients with liver cirrhosis who were being evaluated for orthotopic liver transplantation (OLT) and determined the number of invasive procedures and procedure-related incidences of bleeding in patients with thrombocytopenia. METHODS We studied 121 consecutive patients who were being evaluated for OLT. Thrombocytopenia was defined as a platelet count <150,000/μL and severe thrombocytopenia as a platelet count <75,000/μL. The presence of significant coagulopathy was defined as an international normalized ratio >1.5. Invasive procedures and incidences of procedure-related bleeding were recorded for each patient. RESULTS The prevalence of thrombocytopenia and severe thrombocytopenia were 84% and 51%, respectively. Among the 102 thrombocytopenic patients, 50 (49%) underwent an invasive procedure (32 with severe thrombocytopenia; 64%). Bleeding occurred in 10 of the patients who underwent an invasive procedure (20%). Among the 50 patients who underwent invasive procedure, 32 had severe thrombocytopenia and 18 had moderate thrombocytopenia. Bleeding occurred in 10 of the 32 patients (31%) with severe thrombocytopenia and in none of those with moderate thrombocytopenia. There was no difference in prevalence of significant coagulopathy between patients with severe thrombocytopenia who underwent invasive procedure and bled (3/10; 30%) and those who did not bleed (10/22; 45%). CONCLUSIONS Thrombocytopenia has a high prevalence among patients with advanced liver disease. Bleeding related to invasive procedures occurs most frequently in patients with severe thrombocytopenia, whereas significant coagulopathy does not seem to be associated with bleeding.

Alpha‐fetoprotein is a tumor marker that has been used for surveillance and diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis. The prognostic capability of this marker in patients with HCC has not been clearly defined. In this study our aim was to evaluate the prognostic usefulness of serum alpha‐fetoprotein in patients with well‐compensated cirrhosis, optimal performance status, and small HCC identified during periodic surveillance ultrasound who were treated with curative intent. Among the 3,027 patients included in the Italian Liver Cancer study group database, we selected 205 Child‐Pugh class A and Eastern Cooperative Group Performance Status 0 patients with cirrhosis with a single HCC ≤3 cm of diameter diagnosed during surveillance who were treated with curative intent (hepatic resection, liver transplantation, percutaneous ethanol injection, radiofrequency thermal ablation). Patients were subdivided according to alpha‐fetoprotein serum levels (i.e., normal ≤20 ng/mL; mildly elevated 21‐200 ng/mL; markedly elevated >200 ng/mL). Patient survival, as assessed by the Kaplan‐Meier method, was not significantly different among the three alpha‐fetoprotein classes (P = 0.493). The same result was obtained in the subgroup of patients with a single HCC ≤2 cm (P = 0.714). An alpha‐fetoprotein serum level of 100 ng/mL identified by receiver operating characteristic curve had inadequate accuracy (area under the curve = 0.536, 95% confidence interval = 0.465‐0.606) to discriminate between survivors and deceased patients. Conclusion: Alpha‐fetoprotein serum levels have no prognostic meaning in well‐compensated cirrhosis patients with single, small HCC treated with curative intent. (HEPATOLOGY 2012)

BACKGROUND In the Western world, hepatocellular carcinoma seldom develops in patients without cirrhosis, and reports describing the characteristics of non-cirrhotic patients with hepatocellular carcinoma are rather infrequent. METHODS We evaluated the main clinical characteristics, treatment options, and survival of patients with hepatocellular carcinoma developed in non-cirrhotic liver among the 3027 consecutive cases of hepatocellular carcinoma accrued in the Italian Liver Cancer database during the last 20 years. RESULTS We identified 52 patients with hepatocellular carcinoma in non-cirrhotic livers (1.7% of all hepatocellular carcinomas), 42 with (80.8%) and 10 without (19.2%) chronic liver disease. In patients without chronic liver disease, median tumour diameter was greater compared to patients with chronic liver disease (7.8 versus 4.0 cm, P=0.046). Curative treatment was feasible in 20 patients (38.5%). Median overall survival was 26 months and 5-year survival rate was 23.7%. Detection of hepatocellular carcinoma outside surveillance (P=0.036), advanced hepatocellular carcinoma stage (P<0.0001), and non-curative treatment (P=0.007) were associated with worse prognosis, but tumour stage was the only independent predictor of survival. CONCLUSIONS In Italy, less than 2% of hepatocellular carcinomas develop in a non-cirrhotic liver, and almost never in a normal liver. These patients frequently present with advanced tumours, have low eligibility rates for curative treatment, and have a dismal prognosis despite their preserved liver function.

Background/Aim: In patients with liver cirrhosis, the platelet count/spleen diameter ratio has been validated as a parameter for the noninvasive diagnosis of esophageal varices. Schistosoma infection is a frequent cause of portal hypertension in Middle Eastern countries, and is associated with the development of esophageal varices. In this study we aimed to evaluate the platelet count/spleen diameter ratio as a noninvasive tool for the prediction of the presence of esophageal varices in patients with schistosoma-related chronic liver disease. Patients and Methods: Forty-three patients with hepatosplenic schistosomiasis underwent upper digestive endoscopy to check for the presence of esophageal varices. Furthermore, all patients underwent abdominal ultrasonography, and maximum spleen diameter (in mm) was measured. The platelet count/spleen diameter ratio was calculated in all patients. Results: Esophageal varices were found in 31 patients (72%). Age and gender were not significantly different between patients with and without varices. In patients with varices, median platelet count (82,000/μL versus 172,000/μL, P < 0.0001) and platelet count/spleen diameter ratio (571 versus 1651, P < 0.0001) were significantly lower, while spleen diameter (147 mm versus 109 mm, P = 0.0006) was significantly larger. In multivariate analysis, the platelet count/spleen diameter ratio was the only parameter independently associated with the presence of varices (P < 0.0001). Conclusions: In this study we have validated the use of the platelet count/spleen diameter ratio for the noninvasive diagnosis of esophageal varices in patients with portal hypertension caused by schistosoma infection. In these patients, the platelet count/spleen diameter ratio might be used to allow better rationalization of medical resources and use of endoscopy.

INTRODUCTION Sorafenib, an oral multikinase inhibitor, is the only targeted agent approved for the treatment of patients with hepatocellular carcinoma (HCC) after demonstration to increase overall survival compared to placebo in two randomized phase III study. GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) is the largest, global, non-interventional, prospective study of patients with uHCC (n>3200) treated with sorafenib in real-life clinical practice conditions. Here we report the final analysis of safety and efficacy in the Italian cohort of patients. METHODS Patients with unresectable HCC who are candidates for systemic therapy, and for whom a decision has been made to treat with sorafenib, are eligible for inclusion. Patients demographics disease characteristics and treatment history were recorded at baseline visit. Sorafenib dose, concomitant medications, performance status, liver function, adverse events and efficacy (survival and response rate) were collected throughout the study. RESULTS In the Italian cohort of the GIDEON study 278 patients were included in 36 centers. The global rate of adverse events was 81%. Drug-related events accounted for 67%, mostly of grade 1 and 2, and only 8% were classified as serious. The most common were diarrhea (24%), fatigue (23%), dermatological (14%), rash/exfoliation (10%), hypertension (9%), hemorrage/bleeding of gastrointestinal tract (6%). Overall survival was 14.4 months and time to progression 6.2 months. Objective responses were observed in 14 patients (5%) with 3 complete responses (1%). Stable diseases of at least 6 weeks were observed in 113 patients (41%) with a 30% of disease control rate. DISCUSSION The safety profile of sorafenib in terms of rate and type of adverse events is similar to that emerged in the global international GIDEON study as well as in the pivotal registration studies.INTRODUCTION Sorafenib, an oral multikinase inhibitor, is the only targeted agent approved for the treatment of patients with hepatocellular carcinoma (HCC) after demonstration to increase overall survival compared to placebo in two randomized phase III study.

Nicolini; Lucia Taramasso; Marcello Feasi; Alessandro Grasso; Pasqualina De Leo; Gianfranco Percario; Valentina Bartolacci; Stefania Artioli; Claudio Viscoli; Giovanni Cassola; Roberto Testa; Marco Anselmo; Giovanni Riccio; Vincenzo Savarino; Antonino Picciotto

Goals: To characterize the clinical and treatment pattern in a large population of hepatitis B virus (HBV) patients managed at tertiary referral centers in clinical practice. Background: Successful treatment, either with interferon (IFN) or nucleos(t)ide analogs (NUCs), of chronic HBV infection is associated with improved long-term patient outcome. However, in clinical practice, the actual management of these patients is not well characterized, and data regarding treatment pattern in this setting are lacking. Methods: In this cross-sectional study, we evaluated 505 patients chronically infected with HBV alone and who had at least 1-year follow-up. We assessed indication to, rate of, and type of treatment as well as the characteristics of treated patients. Results: Overall prevalence of positivity for HBe antigen was 19.3%, and the majority of patients had chronic hepatitis (47.5%). Non-Italian patients represented approximately one third of the population (27.1%). Among patients with indication to antiviral therapy (n=318), treatment was actually carried out in 264 patients (83.0%), prevalently with NUCs (65.9%). IFN-treated patients were younger (P<0.001), more frequently male (P=0.025) and HBeAg positive (P=0.003), and less frequently cirrhotics (P<0.001) as compared with patients treated with NUCs. Conclusions: In a geographical area with a low positivity for HBe antigen, antiviral therapy is actually carried out in the majority of patients who have indication to treatment, prevalently with NUCs, whereas IFN treatment is more frequently carried out in young, HBe antigen–positive patients who do not have advanced liver disease.

BackgroundDifferences in the expression of Natural Killer cell receptors have been reported to reflect divergent clinical courses in patients with chronic infections or tumors. However, extensive molecular characterization at the transcriptional level to support this view is lacking. The aim of this work was to characterize baseline differences in purified NK cell transcriptional activity stratified by response to treatment with PEG-IFNα/RBV in patients chronically infected with HCV.MethodsTo this end we here studied by flow cytometer and gene expression profile, phenotypic and transcriptional characteristics of purified NK cells in patients chronically infected with HCV genotype-1 virus who were subsequently treated with PEG-IFNα/RBV. Results were further correlated with divergent clinical response obtained after treatment.ResultsThe pre-treatment transcriptional patterns of purified NK cells from patients subsequently undergoing a sustained virologic response (SVR) clearly segregated from those of non-responder (NR) patients. A set of 476 transcripts, including molecules involved in RNA processing, ubiquitination pathways as well as HLA class II signalling were differently expressed among divergent patients. In addition, treatment outcome was associated with differences in surface expression of NKp30 and NKG2D. A complex relationship was observed that suggested for extensive post-transcriptional editing. Only a small number of the NK cell transcripts identified were correlated with chronic HCV infection/replication indicating that inherent transcriptional activity prevails over environment effects such as viral infection.ConclusionsCollectively, inherent/genetic modulation of NK cell transcription is involved in setting the path to divergent treatment outcomes and could become useful to therapeutic advantage.

Aims Despite the remarkable efficacy shown in clinical practice, concerns have been raised about the costs associated with direct antiviral agent (DAA) therapy. This article presents the real-life costs for DAA treatment sustained by the Italian National Health Service in the Liguria Region (Northern Italy). Methods A retrospective analysis of the cost per care sustained for DAA treatment, relating to the period from January 1 to December 31, 2015 in five centers in Liguria was performed. All patients undergoing DAA-based treatments for hepatitis C virus (HCV) infection were enrolled. On-treatment costs included: HCV treatment, laboratory test, outpatient services, attended visits, drugs used for the management of adverse events (erythropoietin, albumin or red blood cell packs) and inpatient service admissions. Results In total, 327 patients were enrolled. No difference in terms of sustained virologic response (SVR) rate among different treatments was reported. The majority (85.0%) of patients did not report any side effects and only 15 (4.6%) required hospital admission. Forty-two patients (12.8%) required high-cost drugs for the management of adverse events. The overall cost sustained was €14,744,433. DAA±ribavirin (RBV) accounted for the wide majority of this cost (98.9%; €14,585,123). Genotype (GT) 1, the most commonly treated GT, was associated with an average cost of €43,445 per patient. Detailed analysis of the costs for GT 1 showed the treatment based on ritonavir boosted paritaprevir/ombitasvir + dasabuvir±RBV with an average cost of €24,978 (RBV+) and €25,448 (RBV−) per patient was the most cost-effective. The average cost per SVR was €48,184. Once again, the ritonavir boosted paritaprevir/ombitasvir + dasabuvir regimen was associated with the lowest cost/SVR (€25,448/SVR [GT 1b] and similar results for other GTs). Conclusion Antiviral regimen is the major contributor to costs in the treatment of HCV infection. Appropriate regimen selection could result in a major cost saving, which can be reinvested to allow more patients to be treated.
