Exposure to HAV infection in patients with chronic liver disease in Italy, a multicentre study*.

2005

Summary.  We carried out a multicentre study on 2830 patients with chronic liver disease from 79 liver units (25 in northern, 24 in central and 30 in southern Italy) to evaluate naturally acquired immunity against hepatitis A virus (HAV) in relation to age, sex, geographical area of origin and entity of liver disease, and to define the strategy for specific vaccination. Antibody to HAV (anti-HAV) was detected in 1514 (53.5%) of the 2830 patients tested; the prevalence was 50.4% in males and 59.1% in females. Both in central and southern Italy the prevalence of anti-HAV positive subjects increased with increasing age from 43.3 and 44.7%, respectively, in the 0–30-year-old subjects to 80.1 an…

Long-Term Efficacy of Tenofovir Monotherapy for Hepatitis B Virus-Monoinfected Patients After Failure of Nucleoside/Nucleotide Analogues

2010

Tenofovir disoproxil fumarate (TDF) has demonstrated high antiviral efficacy in treatment-naive patients with chronic hepatitis B virus (HBV) infection but experience in nucleoside/nucleotide analogue (NA)-experienced patients is limited. In this retrospective multicenter study we therefore assessed the long-term efficacy of TDF monotherapy in patients with prior failure or resistance to different NA treatments. Criteria for inclusion were HBV DNA levels >4.0 log(10) copies/mL at the start and a minimum, period of TDF therapy for at least 6 months. In all, 131 patients (mean age 42 +/- 12 years, 95 male, 65% hepatitis B e antigen [HBeAg]-positive) were eligible. Pretreatment consisted of…

The HEP-NET B/C co-infection trial: A prospective multicenter study to investigate the efficacy of pegylated interferon-α2b and ribavirin in patients…

2008

Background/Aims The efficacy of pegylated interferon alpha and ribavirin in HBV/HCV co-infected patients is unknown. Methods Nineteen patients with chronic HBV/HCV co-infection (HBsAg and HCV-RNA positive; 10 HCV-genotype 1; 9 HCV-genotype 2 or 3) were included in this prospective multicenter pilot study. Baseline HBV-DNA was negative in 13 individuals. All patients received weight-adjusted PEG-IFN-α2b and ribavirin for 48 weeks. Results In the intent-to-treat analysis, a biochemical and an HCV-RNA response were observed in 12 and 14 patients, respectively (63% and 74%). At the end of the treatment as well as at the end of the follow-up the HCV-RNA response was 93% (14/15) in patients adher…

Current practice of chronic hepatitis B treatment in Southern Italy

2012

Abstract Background Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy. Methods A prospective study enrolling over a six month period (February–July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily). Results Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (…

The aetiology of chronic hepatitis in Italy: results from a multicentre national study

2004

Background: No recent national-level data on the aetiology of chronic hepatitis are available in Italy. Aim: To evaluate the current aetiology of chronic hepatitis in Italy. Patients: A total of 6210 chronic hepatitis patients (both prevalence and incident cases) consecutively admitted to 79 hospitals located throughout Italy were enrolled over a 6-month period in 2001. The hospitals were randomly selected through systematic cluster sampling. Results: The main agent associated with chronic hepatitis was hepatitis C virus, which was found in 76.5% of the patients (in 62.6% it was the only aetiologic factor). Hepatitis B surface antigen was present in the serum of 12.2% of the cases (in 9.2% …

Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.

2014

In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed.A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72).Fifty-one patients (49 men, median age 46 years, range: 32-6…

An evaluation of transient elastography in the discrimination of HBeAg-negative disease from inactive hepatitis B carriers

2009

Summary.  Liver biopsy is frequently required in HBeAg-negative disease to determine the stage of fibrosis. It can be difficult to distinguish cohorts with undetectable HBeAg who may have varying degrees of fibrosis due to different stages of disease. We have assessed the utility of transient elastography (TE) to evaluate differences in HBeAg-negative patients. A total of 220 HBsAg-positive individuals were studied: 125 (group 1) had an inactive HBsAg carrier state and 95 (group 2) were HBeAg-negative, anti-HBe-positive patients with persistently or intermittent elevation of alanine aminotransferase (ALT) and/or HBV DNA >105 copies/mL. Mean stiffness was 4.83 ± 1.2 kPa in group 1 vs 8.53 ± …

Reduction of HbA1c levels following nonsurgical treatment of periodontal disease in type 2 diabetics

2009

Objectives: A study was made of the effect of nonsurgical periodontal treatment upon blood glucose control in type 2 diabetics with periodontal disease. Study design: A pre-post repeated measures analytical design was used, with a PubMed search of the related articles published up until December 2008. Results: The improvement in glycosylated hemoglobin (HbA1c) after nonsurgical periodontal treatment on comparing the baseline (8.0290±1.5539) and final values (7.7806±1.5636) was 0.2483±0.1171, and proved statistically significant (p=0.042). Conclusions: A decrease in HbA1c was observed after treatment, thus indicating improved blood glucose control in type 2 diabetics with periodontal disease.

Human cooperation in groups: variation begets variation

Open Access Published: 04 November 2015 Human cooperation in groups: variation begets variation Pieter van den Berg, Lucas Molleman, Jaakko Junikka, Mikael Puurtinen & Franz J. Weissing Scientific Reports volume 5, Article number: 16144 (2015) Cite this article 383 Accesses 4 Citations 6 Altmetric Metricsdetails Abstract Many experiments on human cooperation have revealed that individuals differ systematically in their tendency to cooperate with others. It has also been shown that individuals condition their behaviour on the overall cooperation level of their peers. Yet, little is known about how individuals respond to heterogeneity in cooperativeness in their neighbourhood. Here, we presen…

Natural history of chronic HBV carriers in northern Italy: morbidity and mortality after 30 years

2004

Background & aims: Increased morbidity and mortality from liver disease have been reported in chronic hepatitis B surface antigen (HBsAg) carriers, but data on survival are equivocal. To assess the impact of hepatitis B virus (HBV) infection on survival and liver-related complications, we re-evaluated, after a mean follow-up of 30 years, a cohort of 296 blood donors excluded from donation 30 years ago when HBsAg screening became mandatory. Methods: Clinical and ultrasound examination and biochemical and virologic tests were performed. The cause of death was recorded and survival was compared with a control population of 157 HBV-negative blood donors selected at baseline. Results: Thirty-two…
