RESUMO

Hepatitis C virus (HCV) infection is a major public health problem in the European Union (EU). An estimated 5.6 million Europeans are chronically infected with a wide range of variation in prevalence across European Union countries. Although HCV continues to spread as a largely "silent pandemic," its elimination is made possible through the availability of the new antiviral drugs and the implementation of prevention practices. On 17 February 2016, the Hepatitis B & C Public Policy Association held the first EU HCV Policy Summit in Brussels. This summit was an historic event as it was the first high-level conference focusing on the elimination of HCV at the European Union level. The meeting brought together the main stakeholders in the field of HCV: clinicians, patient advocacy groups, representatives of key institutions and regional bodies from across European Union; it served as a platform for one of the most significant disease elimination campaigns in Europe and culminated in the presentation of the HCV Elimination Manifesto, calling for the elimination of HCV in Europe by 2030. The launch of the Elimination Manifesto provides a starting point for action in order to make HCV and its elimination in Europe an explicit public health priority, to ensure that patients, civil society groups and other relevant stakeholders will be directly involved in developing and implementing HCV elimination strategies, to pay particular attention to the links between hepatitis C and social marginalization and to introduce a European Hepatitis Awareness Week.

RESUMO

Monitoring of HCV-RNA in blood during antiviral therapy is performed mostly by commercially available reverse transcription polymerase chain reaction-based (RT-PCR) assays, with a lower detection limit of 30-50 IU/mL of HCV-RNA. Use of different tests in the pivotal trials of combination therapy has generated some discordance, in terms of predictive value of the early virological response (EVR). To evaluate whether the use of a more sensitive test, as a qualitative assay based on transcription mediated amplification (TMA) with a lower detection limit of 5-10 IU/mL of HCV-RNA, may obtain a better prediction of EVR and of the ultimate virological outcome, we retrospectively evaluated serial samples from 108 naïve patients with HCV genotype 1 chronic hepatitis, treated with pegylated alpha2b interferon plus ribavirin for 48 weeks and with a 24 weeks stopping rule. Serum samples of patients, obtained during treatment at weeks 4, 12, 24 and 48 and after treatment at week 24, were evaluated by TMA. Comparison of the RT-PCR and TMA assays for the qualitative detection of HCV-RNA showed no significant differences in performance when these tests were used at the end of the treatment period for assessing patients without an on-treatment virological response and those who eventually obtain a sustained virological response. Our results show instead that the use of TMA assay to detect HCV-RNA at 12 and 24 weeks of the combination therapy is more effective than RT-PCR in identifying patients with the highest probability of sustained HCV-RNA clearance.

RESUMO

AIMS: Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. METHODS: A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. RESULTS: Aphthous-like ulcers were found significantly more frequently in coeliac disease, in 22.7% (61/269) of patients with coeliac disease versus 7.1% (41/575) of controls (p=<0.0001; chi-square=41.687; odds ratio=4.3123; 95% confidence interval=2.7664:6.722). Most coeliac disease patients with aphthous-like ulcers and adhering strictly to gluten-free diet (71.7%; 33/46) reported significant improvement on gluten-free diet, with no or reduced episodes of aphthous-like ulcers (p=0.0003; chi-square=13.101; odds ratio=24.67; 95% confidence interval=2.63:231.441). CONCLUSIONS: The epidemiological association found between coeliac disease and aphthous-like ulcers suggests that recurrent aphthous-like ulcers should be considered a risk indicator for coeliac disease, and that gluten-free diet leads to ulcer amelioration.

RESUMO

BACKGROUND: The Chronic Liver Disease Questionnaire is a specific health-related quality of life assessment designed for patients with liver diseases. AIM: The aim of this paper is to report on the validity, reliability and sensitivity to change of the Italian version (Chronic Liver Disease Questionnaire-I) in subjects with HCV infection. SUBJECTS: The Chronic Liver Disease Questionnaire-I was administered to 350 subjects with HCV infection together with the World Health Organization Quality of Life Assessment, abbreviated version, a generic quality of life assessment. METHODS: The instrument was translated from English, backtranslated and reviewed in focus groups in the framework of a large multicentre study. Exploratory factor analysis identified five factors accounting for 65% of the variance of Chronic Liver Disease Questionnaire-I items and only partially overlapping with those found in the original version. RESULTS: The Chronic Liver Disease Questionnaire-I proved to discriminate between subjects with and without comorbid diseases at baseline (t-test = 3.59, p < 0.001). Test-retest reliability was moderate (ICC = 0.60). The Chronic Liver Disease Questionnaire-I was sensitive to change in patients who deteriorated after one month of treatment. Change in the overall Chronic Liver Disease Questionnaire-I score in deteriorated patients was correlated with changes in World Health Organization Quality of Life Assessment, abbreviated version scores in the physical, psychological and environment, but not in the social area. CONCLUSIONS: The Italian version of Chronic Liver Disease Questionnaire is a valid and reliable instrument to be used in cross-sectional and longitudinal studies.

RESUMO

BACKGROUND: Ascites is one of the most frequent severe complications in patients with liver cirrhosis. The treatment of this chronic disease usually requires the prolonged use of albumin, frequently continued even after patients' discharge from the hospital. AIMS: Aim of the study was to define a consensus among Italian physicians with regard to the use of albumin in patients with decompensated cirrhosis and ascites. METHODS: The study adopted the Delphi technique to conduct the consensus activities. All controversial issues related to the use of albumin were identified by the experts' board and proposed to the 68 participating hepatology centres through two subsequent questionnaires. The questionnaires, returned by the specialists involved, were collected and the answers classified to verify the elements on which a consensus was reached. RESULTS: The home use of albumin can help to improve the patient's general conditions and well-being. About 77% of the experts involved considered likely that albumin administration could shorten hospital stays or could reduce the number of hospital admissions. The results of the study, along with a socioeconomic analysis, were presented to the Italian Drug Commission, which subsequently removed the specific hypoalbuminemia level as a prerequisite for having the drug reimbursed by the National Health Service. CONCLUSIONS: For an outpatient prescription, the hypoalbuminemia limit of 2.5 g/dl or less is not sufficient, while the decision whether to administer the drug requires the evaluation of patient's overall clinical conditions as an essential criterion for the prescription of a home treatment with albumin.

RESUMO

BACKGROUND: Sustained virological response (SVR) is the primary objective in the treatment of chronic hepatitis C (CHC). Results from a recent clinical trial of patients with previously untreated CHC demonstrate that the combination of peginterferon alpha-2a and ribavirin produces a greater SVR than interferon alpha-2b and ribavirin combination therapy. However, the cost-effectiveness of peginterferon alpha-2a plus ribavirin in the U.S. setting has not been investigated. METHODS: A Markov model was developed to investigate cost-effectiveness in patients with CHC using genotype to guide treatment duration. SVR and disease progression parameters were derived from the clinical trials and epidemiologic studies. The impact of treatment on life expectancy and costs were projected for a lifetime. Patients who had an SVR were assumed to remain virus-free for the rest of their lives. In genotype 1 patients, the SVRs were 46% for peginterferon alpha-2a plus ribavirin and 36% for interferon alpha-2b plus ribavirin. In genotype 2/3 patients, the SVRs were 76% for peginterferon alpha-2a plus ribavirin and 61% for interferon alpha-2b plus ribavirin. Quality of life and costs were based on estimates from the literature. All costs were based on published U.S. medical care costs and were adjusted to 2003 U.S. dollars. Costs and benefits beyond the first year were discounted at 3%. RESULTS: In genotype 1, peginterferon alpha-2a plus ribavirin increases quality-adjusted life expectancy (QALY) by 0.70 yr compared to interferon alpha-2b plus ribavirin, producing a cost-effectiveness ratio of $2,600 per QALY gained. In genotype 2/3 patients, peginterferon alpha-2a plus ribavirin increases QALY by 1.05 yr in comparison to interferon alpha-2b plus ribavirin. Peginterferon alpha-2a combination therapy in patients with HCV genotype 2 or 3 is dominant (more effective and cost saving) compared to interferon alpha-2b plus ribavirin. Results weighted by genotype prevalence (75% genotype 1; 25% genotype 2 or 3) also show that peginterferon alpha-2a plus ribavirin is dominant. Peginterferon alpha-2a and ribavirin remained cost-effective (below $16,500 per QALY gained) under sensitivity analyses on key clinical and cost parameters. CONCLUSION: Peginterferon alpha-2a in combination with ribavirin with duration of therapy based on genotype, is cost-effective compared with conventional interferon alpha-2b in combination with ribavirin when given to treatment-naïve adults with CHC.

RESUMO

Recommendations are made for controlling the transmission of the hepatitis B and hepatitis C viruses from healthcare workers to patients. These recommendations were based both on the literature and on experts' opinions, obtained during a Consensus Conference. The quality of the published information and of the experts' opinions was classified into 6 levels, based on the source of the information. The recommendations can be summarised as follows: all healthcare workers must undergo hepatitis B virus vaccination and adopt the standard measures for infection control in hospitals; healthcare workers who directly perform invasive procedures must undergo serological testing and the evaluation of markers of viral infection. Those found to be positive for: 1) HBsAg and HBeAg, 2) HBsAg and hepatitis B virus DNA, or 3) anti-hepatitis C virus and hepatitis C virus RNA must abstain from directly performing invasive procedures; no other limitations in their activities are necessary. Infected healthcare workers are urged to inform their patients of their infectious status, although this is left to the discretion of the healthcare worker; whose privacy is guaranteed by law. If exposure to hepatitis B virus occurs, the healthcare worker must undergo prophylaxis with specific immunoglobulins, in addition to vaccination.

RESUMO

Receptors for polymerized human albumin (pHSA-r) are expressed on HBsAg in larger numbers during complete viral replication. We have evaluated the usefulness of pHSA-r as a marker of high-level infection by a comparison with serum HBeAg, liver HBcAg and serum HBV-DNA. One-hundred-and-fifty-seven patients with HBsAg positive chronic liver disease were tested for HBeAg and pHSA-r titre. In 73 of them liver HBcAg was tested by immunofluorescence, while in the remaining 84 serum HBV-DNA was determined. Seventy-three subjects were HBeAg positive, 20/73 were HBcAg positive, and 60/84 had circulating HBV-DNA. The best cut-off for pHSA-r was found at 1:204,800 (sensitivity of 67.6% and specificity of 95.7% in detecting viral replication). At this cut-off the concordance rate between pHSA-r and viral replication (as assessed by HBV-DNA or liver HBcAg) was 83%, a figure similar to that of HBeAg (88%). Three HBeAg negative subjects who were actually complete replicators were identified by the pHSA-r test.
