Direct medical costs associated with the extrahepatic manifestations of hepatitis C infection in Europe.

Hepatitis C virus (HCV) infection is a systemic disease associated with both hepatic and extrahepatic manifestations. The burden associated with the hepatic manifestation of HCV infection has been well documented in Europe, although that of HCV extrahepatic manifestations remains unknown. In this study, we estimated the annual direct medical costs associated with HCV extrahepatic manifestations in five European countries. A previously validated economic model was used to estimate the annual direct medical cost associated with HCV extrahepatic manifestations. Global excess prevalence of extrahepatic manifestations in HCV patients relative to that in non-HCV patients was obtained from a recent meta-analysis. Per-patient per-year inpatient, outpatient and medication costs to treat each extrahepatic manifestation were from the literature, national databases or expert opinion if unavailable otherwise. All costs were adjusted to 2016 euros (€). The overall direct medical costs associated with HCV extrahepatic manifestations were calculated by multiplying the total per-patient per-year costs of each by the respective excess prevalence rates and then by the size of the HCV-infected population in each country. Treatment impact with direct-acting antivirals (DAAs) was explored using HCV extrahepatic manifestations excess prevalence rates among cured patients compared to untreated HCV patients, as sourced from a meta-analysis. The total annual direct medical cost associated with HCV extrahepatic manifestations was estimated to be 2.17 billion euro (€), with a per-HCV-patient cost ranging from €899 to €1647 annually. DAA treatment was projected to result in cost savings of €316 million per year. We find that the annual economic burden of extrahepatic manifestations is significant and may be partly mitigated by treatment with DAAs.

Real-world experience with the all-oral, interferon-free regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir for the treatment of chronic hepatitis C virus infection in the German Hepatitis C Registry.

Real-world studies are relevant to complement clinical trials on novel antiviral therapies against chronic hepatitis C; however, clinical practice data are currently limited. This study investigated effectiveness and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r)±dasabuvir (DSV)±ribavirin (RBV) for treatment of HCV genotype (GT) 1 and GT4 infection in a large real-world cohort. The German Hepatitis C Registry is an observational cohort study prospectively collecting clinical practice data on direct-acting antiviral therapies. Patients with GT1/4 infection treated with OBV/PTV/r±DSV±RBV were analysed. Effectiveness was assessed by sustained virologic response in 558 patients who reached post-treatment week 12 (SVR12). Safety is reported in 1017 patients who initiated treatment. Of the patients, 892 (88%) had GT1 and 125 (12%) had GT4 infection. Prior treatment experience and cirrhosis were reported in 598 (59%) and 228 (22%) patients, respectively. Overall, SVR12 (mITT) was 96% (486/505) in GT1- and 100% (53/53) in GT4 patients. SVR12 rates were high across subgroups including patients with cirrhosis (95%, 123/129), patients with moderate to severe renal impairment (100%, 34/34), and subgroups excluded from registrational trials like patients ≥70 years (96%, 64/67) and failures to prior protease inhibitor treatment (96%, 46/48). Adverse events (AEs) and serious AEs were reported in 52% (525/1017) and 2% (21/1017) of patients, respectively, and led to treatment discontinuation in 1.5% (15/1017) of patients. OBV/PTV/r±DSV±RBV was effective and generally well tolerated for treatment of HCV infection in clinical practice.

Hepatitis C viral dynamics during ribavirin priming differ according to prior treatment response and HCV type.

The mode of action of ribavirin is not completely understood. Ribavirin monotherapy has a measurable antiviral effect, which shows great variability. It might lead to an earlier steady state of plasma concentration and therefore enhance the effect of following combination treatment. The aim of this study was to evaluate the antiviral effect of ribavirin priming and its influence on sustained virologic response after combination treatment in a group of patients with different hepatitis C virus (HCV) types with or without prior treatment experience. Retrospective analysis of 75 patients (37 treatment naïve, 20 prior relapse, 16 prior nonresponse, genotype 1 present in 60 patients) from five centres who received ribavirin priming as part of an individual strategy in order to improve treatment outcome. All patients received ribavirin monotherapy with a mean dose of 14.5 mg kg-1 body weight for a mean of 28 days. After ribavirin priming, dual combination treatment with pegylated interferon alfa and ribavirin was started. The mean HCV RNA decline after ribavirin priming was 0.6 log10  IU mL-1 (P<.001). The initial viral decline depended on HCV type and previous treatment status being highest among prior relapsers (0.8 log10  IU mL-1 ; P=.002) and HCV type 2/3 (1.2 log10  IU mL-1 ; P=.05) and lowest among those with prior nonresponse (0.3 log10  IU mL-1 , P=.01). IFNL4 (formerly IL28B) genotype for rs12979860 and IFNL3 genotype rs8099917 did not influence the initial viral decline. The study demonstrates a significant variability in the viral dynamics and antiviral efficacy of ribavirin monotherapy, which is mainly influenced by prior treatment status. The fact that the lowest response pattern was observed in prior nonresponder patients to pegylated interferon alfa plus ribavirin combination therapy can be taken as a hint that not only the individual interferon, but also the ribavirin sensitivity contributes significantly to the nonresponsive state.

Chronic hepatitis C patients prior to broad access to interferon-free treatments in Germany.

In 2014, the first interferon-free treatment options for chronic Hepatitis C (CHC) became available in Europe introducing a new era of highly effective and well tolerated oral treatment options for CHC. The data from the cross-sectional study CURRENT-C highlights the epidemiological characteristics of patients with CHC in Germany. During the period that the study was conducted, the approval of the combination drugs for the treatment of CHC was imminent.Between June and November 2014, 1471 CHC-patients not receiving anti-HCV treatment were included nationwide in 40 German centers specializing in viral hepatitis. The mean age was 52.4 years with 41.2 % of the patients being female. Presumed route of infection in male patients was most frequently drug use (46.2 %) and blood products in females (22.8 %). The route of infection was unknown in 28.2 % of male and 43.1 % of female patients. Compared to male patients, female patients were older (55.6 vs. 50.1 years) and longer diagnosed with HCV (18 vs. 15 years). First language of the patients was most frequently German (72.2 %), followed by Russian (14.2 %), and Polish (2.9 %). HCV genotype (GT) 1 was found in 73.8 % (1a 29.0 %, 1b 38.4 %), GT2 in 3.5 %, GT3 in 18.3 %, GT4 in 4.2 %, GT5 in 0.2 %, and GT6 in 0.3 %. Liver cirrhosis was diagnosed in 15.7 % of the patients (17.1 % male, 13.7 % female). 43.2 % of the patients had already received HCV treatment, most frequently dual therapy with pegIFN + RBV (75.8 %) or triple therapy with telaprevir or boceprevir (20.3 %). Compared to treatment-naïve patients, pretreated HCV patients were older (55.1 vs. 50.3 years) and more frequently had liver cirrhosis as clinical diagnosis (22.2 % vs. 10.8 %). Patients scheduled for HCV treatment within the next 3 months had higher rates of pre-treatment (49.4 % vs. 37.0 %), and liver cirrhosis (21.4 % vs. 10.0 %).Compared to epidemiological data of Hüppe et al. 1 from 2003 to 2006, Klass et al. 2 stated in 2012 in a comparable setting that the German CHC population were older and had more advanced liver disease. The current data seem to support this ongoing trend towards more difficult to treat patients with an urgent need for new treatment options.

Real-life experience with first generation HCV protease inhibitor therapy in Germany: The prospective, non-interventional PAN cohort.

BACKGROUND AND AIMS: The efficacy and safety of peginterferon alfa-2a (PEG-IFN) plus ribavirin (RBV) and either boceprevir (BOC) or telaprevir (TVR), and physician adherence to treatment algorithms were evaluated in patients included in an ongoing non-interventional study (PAN) enrolling adults with chronic hepatitis C virus (HCV) infection managed in German office-based practices. METHODS: The analysis included HCV genotype 1-infected, treatment-naïve and treatment-experienced patients treated with BOC or TVR. Demographic, treatment history, virological response, safety, and patient management data were collected. RESULTS: Of a total 1087 patients, 58.1 % achieved sustained virological responses (SVR). Response rates were higher in treatment-naïve (BOC 55 %; TVR 63.4 %) and prior relapse patients (BOC 63.2 %; TVR 74.5 %) versus previous null-responders (BOC 14.3 %; TVR 25 %). The most commonly reported adverse event overall was fatigue (60.6 %); 45.8 % patients experienced hemoglobin < 10 g/dL. Patients with cirrhosis had lower rates of SVR versus those without (42.9 % vs. 60.7 %, respectively), and had a higher incidence of serious adverse events (SAEs) (16.7 % vs. 8.6 %, respectively) and treatment discontinuation (44.6 % vs. 25.2 %, respectively). According to recommended response-guided treatment algorithms, about 70 % of patients were managed appropriately, 11/10 % (BOC/TVR) received unnecessarily extended therapy, and 19/7 % (BOC/TVR) received inappropriately shortened therapy. CONCLUSIONS: The efficacy and safety of BOC- and TVR-based triple therapy in this large, "real-world" cohort were largely comparable to that reported in pivotal clinical trials, although SVR rates were lower overall. Recommended futility or treatment extension rules were violated in a substantial proportion of patients with potential implications for response, adverse events and costs.

Point Shear Wave Elastography by Acoustic Radiation Force Impulse Quantification in Comparison to Transient Elastography for the Noninvasive Assessment of Liver Fibrosis in Chronic Hepatitis C: A Prospective International Multicenter Study.

PURPOSE: The aim of the present prospective European multicenter study was to demonstrate the non-inferiority of point shear wave elastography (pSWE) compared to transient elastography (TE) for the assessment of liver fibrosis in patients with chronic hepatitis C. MATERIALS AND METHODS: 241 patients with chronic hepatitis C were prospectively enrolled at 7 European study sites and received pSWE, TE and blood tests. Liver biopsy was performed with histological staging by a central pathologist. In addition, for inclusion of cirrhotic patients, a maximum of 10 % of patients with overt liver cirrhosis confirmed by imaging methods were allowed by protocol (n = 24). RESULTS: Owing to slower than expected recruitment due to a reduction of liver biopsies, the study was closed after 4 years before the target enrollment of 433 patients with 235 patients in the 'intention to diagnose' analysis and 182 patients in the 'per protocol' analysis. Therefore, the non-inferiority margin was enhanced to 0.075 but non-inferiority of pSWE could not be proven. However, Paired comparison of the diagnostic accuracy of pSWE and TE revealed no significant difference between the two methods in the 'intention to diagnose' and 'per protocol' analysis (0.81 vs. 0.85 for F ≥ 2, p = 0.15; 0.88 vs. 0.92 for F ≥ 3, p = 0.11; 0.89 vs. 0.94 for F = 4, p = 0.19). Measurement failure was significantly higher for TE than for pSWE (p = 0.030). CONCLUSION: Non-inferiority of pSWE compared to TE could not be shown. However, the diagnostic accuracy of pSWE and TE was comparable for the noninvasive staging of liver fibrosis in patients with chronic hepatitis C.

Acoustic radiation force impulse imaging for non-invasive assessment of liver fibrosis in chronic hepatitis B.

Acoustic radiation force impulse (ARFI) imaging is a novel ultrasound-based elastography method that is integrated in a conventional ultrasound machine. It might provide an alternative method to transient elastography for the noninvasive assessment of liver fibrosis. While previous studies have shown comparable diagnostic accuracy of ARFI to transient elastography in chronic hepatitis C, the aim of the present prospective multicenter study was to evaluate ARFI for the assessment of liver fibrosis in chronic hepatitis B. ARFI imaging involves the mechanical excitation of tissue using short-duration acoustic pulses to generate localized displacements in tissue. The displacements result in shear-wave propagation which is tracked using ultrasonic, correlation-based methods and recorded in m/s. In the present international prospective study, patients infected with chronic hepatitis B received ARFI imaging, blood tests and if available transient elastography. The results were compared to liver biopsy as reference method analysed by a central pathologist. In 92 of 114 patients, a comparison of ARFI with transient elastography was possible. ARFI imaging and transient elastography correlated significantly with histological fibrosis stage. The diagnostic accuracy expressed as areas under ROC curves for ARFI imaging and transient elastography was 0.75 and 0.83 for the diagnosis of significant fibrosis (F ≥ 2), 0.93 and 0.94 for the diagnosis of severe fibrosis (F ≥ 3), and 0.97 and 0.93 for the diagnosis of liver cirrhosis, respectively. No significant difference was found between ARFI and transient elastography. ARFI imaging is a reliable ultrasound-based method for the assessment of advanced stages of liver fibrosis in chronic hepatitis B.

The influence of HAART on the efficacy and safety of pegylated interferon and ribavirin therapy for the treatment of chronic HCV infection in HIV-positive Individuals.

OBJECTIVE: This study was performed to investigate the impact of HAART versus no HAART and nucleoside free versus nucleoside containing HAART on the efficacy and safety of pegylated interferon and ribavirin therapy for the treatment of chronic HCV infection in HIV/HCV co-infected patients. In addition a control group of HCV mono-infected patients undergoing anti-HCV therapy was evaluated. METHODS: Multicenter, partially randomized, controlled clinical trial. HIV-negative and -positive patients with chronic HCV infection were treated with pegylated interferon alfa-2a and ribavirin (800 - 1200 mg/day) for 24 - 48 weeks in one of four treatment arms: HIV-negative (A), HIV-positive without HAART (B) and HIV-positive on HAART (C). Patients within arm C were randomized to receive open label either a nucleoside containing (C1) or a nucleoside free HAART (C2). RESULTS: 168 patients were available for analysis. By intent-to-treat analysis similar sustained virological response rates (SVR, negative HCV-RNA 24 weeks after the end of therapy) were observed comparing HIV-negative and -positive patients (54% vs. 54%, p = 1.000). Among HIV-positive patients SVR rates were similar between patients off and on HAART (57% vs. 52%, p = 0.708). Higher SVR rates were observed in patients on a nucleoside free HAART compared to patients on a nucleoside containing HAART, though confounding could not be ruled out and in the intent-to-treat analysis the difference was not statistically significant (64% vs. 46%, p = 0.209). CONCLUSIONS: Similar response rates for HCV therapy can be achieved in HIV-positive and -negative patients. Patients on nucleoside free HAART reached at least equal rates of sustained virological response compared to patients on standard HAART.

The German Hep-Net acute hepatitis C cohort: impact of viral and host factors on the initial presentation of acute hepatitis C virus infection.

INTRODUCTION: The impacts of viral load, genotype, age, sex and BMI on the clinical course of acute hepatitis C are poorly defined. Here we studied 259 patients with acute HCV infection recruited in the German Hep-Net data base between 1998 and 2008. Antiviral treatment with interferon alpha was initiated in 171 patients (66 %) within 4 months after the diagnosis of acute hepatitis C. RESULTS: In this cohort (i) the mode of infection was associated with age as iv-drug users were significantly younger than non-iv-drug users while the proportion of patients who acquired HCV by medical procedures increased with age; (ii) patients younger than 30 years were more often infected with genotype 3 (26 % versus 8 % for patients older than 50 years; p = 0.03); (iii) 51 % of patients were icteric and 28 % presented with a 30-fold elevation of liver enzymes, however, no fulminant hepatic failure occurred; (iv) HCV genotype was not associated with disease severity and time to onset of symptoms; (v) low HCV viremia was associated with lower serum AST levels and a longer time from exposure to onset of symptoms; (vi) disease severity was independent from the mode of infection, age, sex and body mass index (BMI). CONCLUSIONS: In this large cohort of patients admitted for antiviral therapy, acute hepatitis C took a rather mild course of disease in the majority of patients. Disease severity was not associated with HCV genotype, viral load, age, sex and BMI.

Treatment of chronic hepatitis C with consensus interferon in relapsers and non-responders to interferon-based therapy.

Over the last decade, enormous advances have been achieved in the treatment of chronic hepatitis C. However, the success of the established standard therapy with PEG-IFN and ribavirin is limited and needs further therapeutic options especially for the difficult-to-treat patients with genotype 1, patients with liver cirrhosis, patients with relapse or breakthrough and non-responders after a PEG-IFN/ribavirin combination therapy. In those cases, a daily treatment with CIFN/ribavirin could be a promising concept, before considering non-curable concepts as the long-term IFN maintenance therapy, especially in cases with advanced liver fibrosis. Daily treatments need high motivated and compliant patients. Concepts to optimize current therapies as the use of CIFN or the high dose PEG-IFN therapy are necessary until new kinds of therapy are available.

Monoclonal antibody therapy for resected Dukes' C colorectal cancer: seven-year outcome of a multicenter randomized trial.

PURPOSE: As previously shown, antibody treatment increased survival of patients with resected colorectal cancer of stage Dukes' C. Since the 5-year analysis was criticized because of the wide range (2.7 to 7.5 years) of follow-up time, we performed a 7-year analysis with only four of 189 patients monitored for less than 5 years. PATIENTS AND METHODS: A total of 189 patients with resected Dukes' C colorectal cancer were randomly allocated to infusions of a total of 900 mg 17-1A antibody, 500 mg postoperatively followed by 4 monthly doses of 100 mg (n=99), or to observation only (n=90). Primary end points were overall survival and disease-free interval. Patients were stratified by a dynamic randomization according to center, sex, location of tumor, number of affected lymph nodes, and preoperative carcinoembryonic antigen concentration. RESULTS: Randomization produced balanced distribution of risk factors. After 7 years of follow-up evaluation, treatment had reduced overall mortality by 32% (Cox's proportional hazard, P < .01; log-rank, P=.01) and decreased the recurrence rate by 23% (Cox's proportional hazard, P < .04; log-rank, P=.07). The intention-to-treat analysis gave a significant effect for overall survival (Cox's proportional hazard, P < .01; log-rank, P=.02) and disease-free survival (Cox's proportional hazard, P=.02; log-rank, P=.11 ). While distant metastases were significantly reduced (Cox's proportional hazard, P=.004; log-rank, P=.004), local relapses were not (Cox's proportional hazard, P=.65; log-rank, P=.52). This differential effect of 17-1A antibody on disseminated isolated tumor cells versus occult local satellites may explain the increased significance seen in the overall survival. CONCLUSION: The now-matured study shows that 17-1A antibody administered after surgery prevents the development of distant metastasis in approximately one third of patients. The therapeutic effect is maintained after 7 years of follow-up evaluation.

Randomised clinical trial: alisporivir combined with peginterferon and ribavirin in treatment-naïve patients with chronic HCV genotype 1 infection (ESSENTIAL II).

BACKGROUND: Alisporivir (ALV) is an oral, host-targeting agent with pangenotypic anti-hepatitis C virus (HCV) activity and a high barrier to resistance. AIM: To evaluate efficacy and safety of ALV plus peginterferon-α2a and ribavirin (PR) in treatment-naïve patients with chronic HCV genotype 1 infection. METHODS: Double-blind, randomised, placebo-controlled, Phase 3 study evaluating ALV 600 mg once daily [response-guided therapy (RGT) for 24 or 48 weeks or 48 weeks fixed duration] or ALV 400 mg twice daily RGT with PR, compared to PR alone. Following a Food and Drug Administration partial clinical hold, ALV/placebo was discontinued and patients completed treatment with PR only. At that time, 87% of patients had received ≥12 weeks and 20% had received ≥24 weeks of ALV/PR triple therapy. RESULTS: A total of 1081 patients were randomised (12% cirrhosis, 55% CT/TT IL28B). Addition of ALV to PR improved virological response in a dose-dependent fashion. Overall, sustained virological response (SVR12; primary endpoint) was 69% in all ALV groups vs. 53% in PR control. Highest SVR12 (90%) was achieved in patients treated with ALV 400 mg twice daily and PR for >24 weeks. Seven cases of pancreatitis were reported, with similar frequency between ALV/PR and PR control groups (0.6% vs. 0.8% respectively). Adverse events seen more frequently with ALV/PR than with PR alone were anaemia, thrombocytopenia, hyperbilirubinaemia and hypertension. CONCLUSIONS: Alisporivir, especially the 400 mg twice daily regimen, increased efficacy of PR therapy in treatment-naïve patients with HCV genotype 1 infection. The mechanism of action and pangenotypic activity suggest that alisporivir could be useful in interferon-free combination regimens.

Phase II trial of 5-fluorouracil and recombinant interferon alfa-2B in metastatic colorectal carcinoma.

Between February 1990 and April 1991, 59 previously untreated patients with progressive and/or symptomatic metastatic colorectal carcinoma were enrolled in a phase II study of 5-fluorouracil (5-FU) and interferon alfa-2b (IFN-alpha). 5-FU 750 mg/m2/day was administered as continuous infusion for 5 days, then weekly in a dose of 750 mg/m2 as intravenous push injection starting on day 15. IFN-alpha 9 MU was given subcutaneously three times a week. Treatment was given for a maximum of 6 months. 55 patients are evaluable for response and 51 for toxicity. 17 patients (31%) achieved a partial remission, 15 (27%) had stable disease and 21 patients (38%) had progressive disease. Median duration of remission was 5 months and median survival for all patients 10 months. Toxicity was important with two treatment-related deaths and severe leukopenia, fever, diarrhoea and mucositis in about one third of the patients. In our opinion, this regimen is effective but rather toxic in metastatic colorectal carcinoma.

Treatment of metastatic colorectal carcinoma with a combination of fluorouracil and recombinant interferon alfa-2b: preliminary data of a phase II study.

From March 1990 to January 1991 52 previously untreated patients with metastatic colorectal carcinoma were enrolled in a phase II study with the combination of interferon alfa-2b and fluorouracil (5-FU). 5-FU 750 mg/m2 per day was administered as continuous infusion for 5 days, then weekly in a dose of 750 mg/m2 as IV push injection starting on day 15. Interferon alfa-2b (Intron A, ESSEX Pharma) 9 x 10(6) units was given subcutaneously three times per week. Response to therapy was evaluated after 3 and 6 months. So far, data on response rates and toxicity are available in 32 patients: partial remission, 10 patients (31%); stable disease, nine patients (28%); progressive disease, 12 patients (37%); toxic deaths, two patients (6%). Projected median survival has not been reached after 11 months. In about one third of the patients severe side effects occurred with leukopenia grade 3 and 4, diarrhea, mucositis and septic complications being the clinically most important. We think that this combination is an effective but toxic regimen in advanced colorectal carcinoma. Further studies must reevaluate both the schedule and the doses of the drugs administered.

High rate of chronicity in HCV infection determined by antibody confirmatory assay and PCR in 4110 patients during long-term follow-up.

BACKGROUND: It is still unclear how many patients with hepatitis C virus (HCV) antibodies have viremia and hence are infectious. OBJECTIVES: To determine the chronicity of HCV infection by correlation of HCV antibodies with presence of viremia in long-term follow-up. STUDY DESIGN: In a longitudinal study sera of 4110 patients were analyzed with second generation HCV-enzyme immunoassay (EIA) and polymerase chain reaction (PCR). Only those patients were included in this study in whom sequential serum samples over a period of 2 years were available. To avoid preanalytical and analytical failures, we used a transport solution to prevent RNA degradation and a four-antigen recombinant immunoblot assay, established in our laboratory, for confirmation of antibody reactivity. RESULTS: Of 2815 patients with confirmed HCV antibodies 2784 (98.9%) were also positive in HCV-PCR assay. False reactive EIA results were detected in 177 (13.7%) individuals as shown by confirmatory assay and PCR. Only one patient (0.04%) spontaneously lost detectable HCV viremia and subsequently HCV-specific antibodies. CONCLUSIONS: Our study clearly demonstrates that presence of confirmed HCV-specific antibodies correlates significantly (98.9%; P < 0.001) with HCV viremia, and that spontaneous loss of viremia is a very rare event in HCV infection. We also found that elimination of HCV infection is not sufficiently predicted by the loss of detectable viremia in PCR, but can be concluded from the disappearance of virus-specific antibodies.

[Transjugular liver biopsy: trucut or aspiration biopsy with modified Ross needles?]. / Die transjuguläre Leberbiopsie: Trucut- oder Aspirationsbiopsie mit modifizierter Ross-Nadel? Ergebnisse einer Meta-Analyse und ökonomische Aspekte.

PURPOSE: The transjugular liver biopsy is performed in patients with coagulopathy to evaluate diffuse hepatopathies. Using a jugular venous access, a liver vein is cannulated and a transvascular biopsy taken. The two techniques in use are the aspiration biopsy with a modified 15G or 16G Ross needle used for TIPS and the core biopsy with a Trucut needle. The sampling is quite similar for these techniques, but the costs are significantly different. This study is a meta-analysis of data published on both techniques to search for clinical evidence that justifies the use of the more expensive Trucut needle or that finds aspiration with the less expensive Ross needle equivalent. MATERIALS AND METHODS: The study includes 16 publications that were published between 1996 and 2002 and provided reliable information on technical success rate, complications and adequate histology. The data on 1374 procedures were analyzed, comprising 436 aspiration biopsies and 938 Trucut biopsies. RESULTS: Considering both procedures together, 95.9 % of the procedures were technically successful and 92.2% of the histologic samples diagnostically adequate. The technical success rate was 96.7 % for the Trucut-biopsies and 94.4 % for the aspiration biopsies. The corresponding rates of obtaining diagnostically adequate histologic samples were 92.5 % and 91.5 %, respectively. The complication rate of the entire population studied was 0.65 % without significant difference found between the two methods. With a list price of 420 Euro, the Trucut system costs about 200 Euro more than the Ross needle, which is listed as approximately 220 Euro. CONCLUSION: In the absence of any significant differences between both techniques for transjugular liver biopsies, economic considerations make the aspiration biopsy with the modified Ross needle preferable over the Trucut needle biopsy.

Pancreaticoduodenal artery aneurysm--a life-threatening cause of gastrointestinal hemorrhage: case report and review of the literature.

Gastrointestinal bleeding caused by erosion of a pancreaticoduodenal artery aneurysm in patients with pancreatitis is a rare but potentially life threatening disease. In this case report, the successful treatment of a patient bleeding from a ruptured pancreaticoduodenal artery aneurysm is described. A review of the literature of reported cases discusses the value of early angiographic intervention in patients with unexplained gastrointestinal hemorrhage and suspected rupture of an aneurysm.
