Early viral clearance and sustained response in chronic hepatitis C: a controlled trial of interferon and ribavirin after high-dose interferon induct…

2002

High-dose induction with alpha-interferon induces early viral clearance of hepatitis C and combined with ribavirin enhances sustained response. We assess whether adding ribavirin after viral clearance obtained by alpha-interferon induction increased the rate of viral eradication.Forty-one naïve patients with chronic hepatitis C were randomised to receive, after 4 weeks of 10 mU daily of alpha-interferon (induction), 3 mU daily for 22 weeks and 3 mU thrice weekly for 26 weeks of either interferon alone (monotherapy) or interferon plus 1000-1200 mg daily of ribavirin (combination therapy). At the end of the induction phase, 23 (56%) subjects had cleared HCV-RNA. During therapy, breakthrough w…

HCV viraemia is more important than genotype as a predictor of response to interferon in sicily (Southern Italy)

1996

Abstract Background/Aims: To investigate host- and virus-related factors predictive of early and sustained alanine aminotransferase normalization after interferon therapy for HCV-related chronic liver disease, in an area where genotype 1 is highly prevalent. Methods: We studied 100 patients with HCV-RNA positive chronic liver disease (73 chronic hepatitis and 27 cirrhosis) undergoing alpha-interferon treatment. Thirty-four patients had an early response but relapsed, 15 patients remained into sustained response for at least 12 months after therapy, and 51 patients did not respond. Serum HCV-RNA levels were assessed by bDNA (Chiron), and genotype by LiPA (Innogenetics) and by sequencing of t…

Overcoming a “Probable” Diagnosis in Antimitochondrial Antibody Negative Primary Biliary Cirrhosis: Study of 100 Sera and Review of the Literature

2010

Serum anti-mitochondrial antibodies (AMA) are the serological hallmark of primary biliary cirrhosis (PBC), yet up to 15% of PBC sera are AMA negative at routine indirect immunofluorescence (IIF) while being referred to as “probable” cases. The diagnostic role of PBC-specific antinuclear antibodies (ANA) remains to be determined. We will report herein data on the accuracy of new laboratory tools for AMA and PBC-specific ANA in a large series of PBC sera that were AMA-negative at IIF. We will also provide a discussion of the history and current status of AMA detection methods. We included IIF AMA-negative PBC sera (n = 100) and sera from patients with other chronic liver diseases (n = 104) th…

The burden of HBV infection in HCV patients in Italy and the risk of reactivation under DAA therapy

2019

Background: There is increasing awareness of HBV reactivation in HCV-RNA-positive/HBV-coinfected patients with chronic liver disease (CLD) treated with oral direct-acting antivirals (DAAs). Aim: To provide figures on the prevalence of HBV markers in HCV-RNA-positive subjects in Italy, where these findings are lacking. Methods: All subjects aged ≥18 years with CLD consecutively referring to Italian liver units located throughout country were prospectively enrolled in two national surveys in 2001 and 2014. Results: The total number of HCV-RNA-positive cases was 6984; 356 (5.1%) subjects vaccinated against HBV were excluded. A total of 6628 cases were evaluated. The prevalence rates of HBsAg, …

Transmission of hepatitis B and hepatitis delta viruses in the households of chronic hepatitis B surface antigen carriers: A regression analysis of i…

1991

Abstract To evaluate whether clinical and laboratory features of a hepatitis B surface antigen (HBsAg) carrier can predict risks of infection, its chronicity, and the development of liver disease among close contacts, the authors studied a cohort of 994 first degree relatives or cohabitants (household contacts) of 226 non-drug-addicted chronic HBsAg carriers (index cases), of whom 77% had liver disease and 26% were superinfected by hepatitis D virus (HDV). A logistic form of regression analysis was used to assess the role of each feature in the index case as predictor of hepatitis B virus (HBV)- and HDV-related outcomes among household contacts. Six models of risk, expressed as odds ratios,…

HBV-DNA suppression and disease course in HBV cirrhosis patients on long-term lamivudine therapy

2005

In hepatitis B virus (HBV) cirrhosis patients on long-term lamivudine (LAM), the relationships between HBV suppression, development of viral resistance and disease outcome are unclear. We analysed the dynamic of serum HBV-DNA and its relationship with the clinical course of 59 patients (52 males, mean age 51.4 ±8.4 years, 12 HBeAg positive and 47 HBeAg negative, and 57 genotype D and two genotype A) with cirrhosis (45 in Child-Turcotte-Pugh class A) and high levels of serum HBV-DNA (median 14.7x107 genomes/ml) treated with LAM [median (range): 44 (15–78) months]. A total of 50 patients (84.7%) achieved a virological response (serum HBV-DNA negative by PCR) during the first 6 months of ther…

Ultrasound Parameters Can Accurately Predict the Risk of Malignancy in Patients with “Indeterminate TIR3b” Cytology Nodules: A Prospectiv…

2023

The increase in the incidence of thyroid nodules with cytological findings of TIR3b requires the identification of predictive factors of malignancy. We prospectively evaluated 2160 patients from January 2018 to June 2022 and enrolled 103 patients with indeterminate cytology TIR3b nodules who underwent total (73 patients) and hemi-thyroidectomy (30 patients). Among them, 61 had a histological diagnosis of malignancy (30 classic papillary thyroid carcinoma, 19 had follicular papillary thyroid carcinoma variant, 3 had Hurtle cell carcinoma and 9 had follicular thyroid carcinoma), while 42 had a benign histology. Clinical, ultrasonographic and cytological characteristics were recorded. In addit…

1994

A multicenter longitudinal study was performed to assess the survival of hepatitis B surface antigen positive compensated cirrhosis, primarily in relation to hepatitis B virus replication and hepatitis delta virus infection, and to construct a prognostic index based on entry characteristics. This cohort study involved nine university medical centers in Europe. Three hundred and sixty-six Caucasian HBsAg positive patients with cirrhosis who had never had clinical manifestations of hepatic decompensation were enrolled and followed for a mean period of 72 months (6 to 202 months). Inclusion criteria were biopsy-proven cirrhosis, information on serum hepatitis B e antigen and antibody to hepati…

Decreasing role of HCV and HBV infections as aetiological factors of hepatocellular carcinoma in Italy

2019

Background: The epidemiology of hepatocellular carcinoma (HCC) is characterized by a dynamical temporal trend of well-established and emerging risk factors. Methods: We evaluated the temporal trend of aetiological factors of HCC over the last two decades in Italy. HCC cases were recruited from two previously published national studies in 1996 and in 2008 and HCC cases were also enlisted from two national surveys in 2001 and in 2014 enrolling consecutive subjects with chronic liver disease (CLD) referring to more than 80 liver units scattered all over the country for a 6-monthperiod. Results: Out of the 9997 subjects with CLD recruited in 2001 and the 2408 recruited in 2014, 3.3% and 5.7% (P…

Drugs and Toxins Effects on the Liver

2011

Drug induced hepatotoxicity can be defined as a liver injury caused by drug or herbal medicines leading to liver test abnormalities or to a liver dysfunction with a reasonable exclusion of the other competing aetiologies. The liver has a central function in the metabolism of the xenobiotics, and as a result it may be susceptible to its toxic or idiosyncratic effects. While the overall incidence of drug induced liver injury (DILI) is infrequent (1 in 10.000 to 100.000 persons exposed), the impact is significant in the general population, with broad implications for patients, physicians, pharmaceutical industries and governmental regulatory agencies. DILI is the principle reason for the termi…

Serology in adults with celiac disease: limited accuracy in patients with mild histological lesions.

2010

Celiac disease (CD) is a gluten-triggered enteropathy, presenting with insidious clinical patterns. It can occasionally be diagnosed in asymptomatic subjects. Our aim was to define the relationship among symptoms at diagnosis, serological markers [tissue transglutaminase antibodies (tTGA), anti-endomysium antibodies (EMA) anti-actin antibodies (AAA)] and degree of mucosal damage. A total of 68 consecutive adult patients with CD were enrolled. Intestinal biopsies were scored according to the Marsh classification modified by Oberhuber: I–II minimal lesions or absent villous atrophy; IIIA partial villous atrophy; IIIB–C total villous atrophy (TVA). HLA-typing was done for all patients. No asso…

Etiological factors of chronic hepatitis in Italy: a 2014 national survey.

2017

Background The last Italian prevalence survey on chronic hepatitis (CH) conducted in 2001 showed that the hepatitis C virus (HCV) was the main agent associated with CH. Aim The aim of this study was to evaluate epidemiological changes in CH occurring after 13 years. Patients and methods Enrollment of 1392 CH consecutive patients referred to 16 Italian liver units in 2014 scattered all over the country (four in the North, four in the Center, four in the South, and four in the Islands) was performed. Results The mean age of the patients was 58.3 years, with a sex ratio (male/female) of 1.5. HCV infection (also with other etiologies) continues to be the most prevalent etiology (58.1%). However…

The impact of antiviral therapy on the course of chronic HCV infection: A systematic review

2003

Aim. Chronic hepatitis C is a progressive disease that leads to liver cirrhosis and hepatocellular carcinoma in a period ranging from 10 to 30 y. Many factors have been related to disease progression and, among them, persistent HCV replication has been advocated as one of the major determinant of hepatic deterioration. With this respect any treatment of chronic hepatitis C is mainly aimed to reduce necro-inflammation by suppressing viral activity in the long-term. We evaluated the persistence of HCV clearance after interferon therapy during follow-up in patients considered as long-term responders. Secondly, we analyzed the rate of progression from hepatitis to cirrhosis and hepatocellular c…

Liver disease in chelated transfusion-dependent thalassemics: the role of iron overload and chronic hepatitis C.

2008

Iron overload and hepatitis virus C infection cause liver fibrosis in thalassemics. In a monocentric retrospective analysis of liver disease in a cohort of 191 transfusion-dependent thalassemics, in 126 patients who had undergone liver biopsy (mean age 17.2 years; 58 hepatitis virus C-RNA positive and 68 hepatitis virus C-RNA negative) the liver iron concentration (median 2.4 mg/gr dry liver weight) was closely related to serum ferritin levels (R = 0.58; p<0.0001). Male gender (OR 4.12) and serum hepatitis virus C-RNA positivity (OR 11.04) were independent risk factors for advanced liver fibrosis. The majority of hepatitis virus C-RNA negative patients with low iron load did not develop liv…

Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.

2005

PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…

Genome-wide meta-analyses identify three loci associated with primary biliary cirrhosis.

2010

A genome-wide association screen for primary biliary cirrhosis risk alleles was performed in an Italian cohort. The results from the Italian cohort replicated IL12A and IL12RB associations, and a combined meta-analysis using a Canadian dataset identified newly associated loci at SPIB (P = 7.9 × 10&#8722;11, odds ratio (OR) = 1.46), IRF5-TNPO3 (P = 2.8 × 10&#8722;10, OR = 1.63) and 17q12-21 (P = 1.7 × 10&#8722;10, OR = 1.38).

Hepatitis C virus replication in ‘autoimmune’ chronic hepatitis

1991

Abstract Both high and low anti-hepatitis C virus antibody (anti-HCV) prevalence has been reported in autoimmune chronic active hepatitis. Therefore, we studied 15 consecutive HBsAg-negative, ELISA anti-HCV-positive, autoantibody-positive patients with biopsy proven chronic active hepatitis in order to confirm ELISA specificity by immunoblot test (RIBA-HCV), and to evaluate HCV replication by serum HCV-RNA. Nine patients were anti-nuclear, three type 1 anti-liver-kidney microsomal and three anti-smooth muscle antibody positive. None had associated autoimmune disease. All cases showed mild clinical disease and only moderate necroinflammatory activity. Response to prednisone was poor. RIBA-HC…

Fibrosis evaluation by transient elastography in patients with long-term sustained HCV clearance.

2013

Background: Reversibility of advanced fibrosis after HCV-clearance is an important goal of therapy. Objectives: Measuring liver stiffness (LS) by transient elastography (TE) might be helpful in this setting. Patients and Methods: We evaluated 104 patients with biopsy-proven chronic hepatitis C (CHC) and sustained virological response (SVR) after Peg-Interferon (IFN) plus ribavirin since at least 18 months. HCV-eradication was confirmed searching for serum HCV-RNA (TMA® sensitivity > 5-10 IU/ml). Data from literature reported the best LS cut-off values for different stages of liver fibrosis were 7.1 kPa for Metavir stage 2 (F2), 9.5 kPa for F3 and 12.5 for cirrhosis (F4). Results: TE was not…

2006

AIM: To assess the efficacy of different schedules of consensus interferon (CIFN) plus ribavirin in retreating chronic hepatitis C patients who relapsed after recombinant interferon (rIFN) monotherapy. METHODS: Forty-five patients (34 males and 11 females) with chronic hepatitis due to hepatitis C virus (HCV) genotype 1 who relapsed after a previous course of rIFN monotherapy were randomized to receive 9 μg CIFN three times per week for 52 wk (group A, n = 22) or 18 μg CIFN three times per week for 52 wk (group B, n = 23) in combination with ribavirin 800 to 1200 mg daily for 52 wk (according to body weight). Virological response was evaluated at week 24 (EVR), at the end of treatment (ETR)…

Duration of HCV infection as a predictor of nonresponse to interferon

1996

Duration of hepatitis C virus (HCV) infection is a key feature in determining responsiveness to interferon (IFN). Studies assessing its value as a predictive factor in chronic HCV infection show that a long duration of infection reduces the likelihood of a sustained response to IFN (defined as ALT normalization and clearance of serum HCV-RNA). The effect of HCV infection duration is independent of the presence of cirrhosis and level of HCV viremia. Meta-analysis of IFN trials in acute HCV infection shows an obvious effect of the drug on long-term ALT normalization and HCV-RNA clearance. Treatment of HCV infection during the acute or early chronic phase could therefore maximize therapeutic e…

Impact of hepatitis C virus infection on lifestyle

2007

AIM: To evaluate the impact of the diagnosis of hepatitis C infection on lifestyle habits such as smoking, drinking, sports activity and diet. METHODS: A self-administered, anonymous question-naire was offered to out-patients with HCV infection consecutively attending three clinical centres in Italy. RESULTS: Of the 275 respondents, 62.2% (171) were male. Mean age was 51 (range 20-80) years. Overall, after the diagnosis of hepatitis C, 74.5% of drinkers had modified (giving up or reducing) alcohol consumption, 21.3% of smokers had modified their habits and 32.3% of subjects who reported sports activity had either stopped or reduced frequency of activity or chose a less fatiguing sport. Sixt…

Gender differences in chronic HBsAg carriers in Italy: Evidence for the independent role of male sex in severity of liver disease

2015

It has been shown that sexual hormones have an opposite effect on hepatic fibrosis progression and hepatocellular carcinoma development. Sex differences among 2,762 chronic HBsAg carriers consecutively referring Italian hospitals in 2001 and in 2007 have been evaluated, particularly focusing on the role of gender on severity of liver disease. The overall sex ratio (males/females) was 2.6. Females were more likely born abroad and new diagnosis cases; but less likely HIV coinfected. No sex difference was observed regarding coinfection with other hepatitis viruses. The sex ratio linearly increased with increasing severity of liver disease, being 1.3 in normal ALT, 2.8 in chronic hepatitis, 3.6…

Clinical course and outcomes of drug-induced liver injury: Nimesulide as the first implicated medication

2010

Abstract Background and aims Drug-induced liver injury (DILI) is the most common cause of death from acute liver failure, and accounts for approximately 13% of cases of acute liver failure in the United States. The clinical presentation of DILI covers a wide spectrum, from asymptomatic liver test abnormalities to symptomatic acute liver disease, prolonged jaundice and disability, or overt acute or subacute liver failure. The aim of our study was to evaluate the number of DILI cases admitted to our Unit and to identify the drugs responsible. Thus, we reviewed all clinical records of patients with DILI admitted to our Unit from 1996 to 2006. Patients and methods A database was constructed, re…

Blood urea nitrogen to creatinine ratio is associated with congestion and mortality in heart failure patients with renal dysfunction

2015

Renal dysfunction (RD) and venous congestion are related and common in heart failure (HF). Studies suggest that venous congestion may be the primary driver of RD in HF. In this study, we sought to investigate retrospectively the relationship between common measures of renal function with caval congestion and mortality among outpatients with HF and RD. We reviewed data from 103 HF outpatients (45 males, mean age 74 years, ejection fraction 41.8 ± 11.6 %) with estimated glomerular filtration rate (eGFR) of 25.5 (adjusted OR 2.98, p 0.015) and eGFR ≤45.8 (adjusted OR 5.38, p 0.002) identify patients at risk for caval congestion; a BUN/Cr >23.7 was the best predictor of impaired collapsibility …

Experts' opinions on the role of liver biopsy in HCV infection: A Delphi survey by the Italian Association of Hospital Gastroenterologists (A.I.G.O.)

2005

Background/Aims: Liver biopsy represents the gold standard to establish a diagnosis in all liver patients, but its current position in chronic viral hepatitis is questioned. We aimed to create a consensus on best practice of use of liver biopsy in the management of chronic HCV infection. Methods: We applied the Delphi method to 12 clinical scenarios of chronic HCV infection, to assess the extent of agreement (consensus measurement) and to resolve disagreement (consensus development) on the appropriateness of liver biopsy. Results: Among 108 chosen hepatologists, 61 (56.5%) accepted to participate to the first-round survey. In four patients the majority of experts (from 61.4 to 86.2%) agreed…

Diabetic foot ulcers: Retrospective comparative analysis from Sicily between two eras

2021

Aim The aim of this study was to analyze changes in the incidence, management and mortality of DFU in Sicilian Type 2 diabetic patients hospitalized between two eras, i.e. 2008–2013 and 2014–2019. Methods We compared the two eras, era1: 2008–13, era2: 2014–19. In era 1, n = 149, and in era 2, n = 181 patients were retrospectively enrolled. Results In the population hospitalized for DFU in 2008–2013, 59.1% of males and 40.9% of females died, whilst in 2014–2019 65.9% of males and 34.1% of females died. Moderate chronic kidney disease (CKD) was significantly higher in patients that had died than in ones that were alive (33% vs. 43%, p &lt; 0.001), just as CKD was severe (14.5% vs. 4%, p &lt;…

Pegylated interferon therapy in chronic hepatitis C: lights and shadows of an innovative treatment

2007

Abstract Pegylated interferon (PEG-IFN) in combination with ribavirin is the standard of treatment for chronic hepatitis C. Several viral and host factors influence the outcome of treatment, such as hepatitis C virus (HCV) genotype, baseline viral load, viral kinetics, race, body weight, advanced liver disease, HIV co-infection, and adherence to therapy. Monitoring the response of HCV to treatment during the early time points (4 weeks or 12 weeks) after initiation of therapy has emerged as a critical tool to predict sustained virologic response (SVR), defined as undetectable serum HCV RNA 24 weeks after the end of therapy. To counterbalance the influence of host and viral factors, treatment…

Perception of the Role of Food and Dietary Modifications in Patients with Inflammatory Bowel Disease: Impact on Lifestyle

2021

Background: Diet has a relevant role in triggering symptoms in inflammatory bowel disease (IBD) from the patients’ perspective, but there is gap the between patients’ and doctors’ perceptions. Few studies have addressed this topic. The aim of this study was to evaluate food habits and nutrition knowledge in a homogeneous cohort of patients with IBD from southern Italy. Methods: 167 consecutive patients with IBD were recruited. The survey was based on the administration of a semi-structured questionnaire assessing demographics, disease features, dietary behavior, and food intolerance. Results: The majority of patients did not consider food a cause of their disease. However more than 80% chan…

The association between education level and chronic liver disease of any etiology

2020

Abstract Background The potential link between educational level and chronic liver diseases (CLD) were explored using the mortality records of liver cirrhosis, which lack accuracy and are unable to identify the different etiological factors of liver cirrhosis. Information on the association of low educational level with the severity of CLD is lacking. Aim To evaluate the potential association linking education level to etiology and clinical stage of CLD cases. Methods Consecutive enrolment of 11,107 subjects with CLD aged≥18 years prospectively recruited in two national surveys in 2001 and 2014 at one of the participating Italian liver units throughout the country. Subjects were pooled in t…

1996

Abstract Aims: To compare the long-term effects of brief and prolonged therapy with alpha-n 1 interferon for transfusion-associated chronic hepatitis C. Methods: One hundred and sixteen subjects (male/female 4868, mean age 46.9 years) were studied. Sixty patients were randomised to brief treatment (group 1: interferon 5 Mu/msq. t.i.w. for 2 months, then 3 Mu/msq. t.i.w. for 4 months), and 56 to prolonged treatment (group 2: interferon 5 Mu/msq. t.i.w. for 2 months, then 3 Mu/msq. t.i.w. for 10 months). All were followed for 12 months after stopping interferon. Results: The early response rate was 47.4% (Group 1 [45%], Group 2 [50%]). No "breakthrough" reactivations were observed. The early …

Anti-tumour necrosis factor-α antibodies and B cell homeostasis in human inflammatory bowel diseases

2017

Background The expression of CD70 on T cells is greatly enhanced by antigen-presenting cell (APC)-associated signals, such as tumour necrosis factor(TNF)-α, which is constitutionally high in patients with inflammatory bowel disease (IBD). Experimentally, the chronic activation of CD27 as a result of the constitutive expression of CD70 leads to the demise of B cells in bone marrow (BM) and the secondary lymphoid organs. The aim of this study was to assess the number and phenotype of circulating B cell in untreated IBD patients and their counterparts treated with biological anti-TNF drugs. Methods The study involved 13 untreated IBD patients, 36 IBD patients treated with biological drugs, and…

2011

AIM: To evaluate the clinical relevance of each cofactor on clinical presentation of chronic hepatitis B. METHODS: Out of 1366 hepatitis B surface antigen (HBsAg) positive subjects consecutively observed in 79 Italian hospitals, 53 (4.3%) showed as the only cofactor hepatitis D virus (HDV) infection [hepatitis B virus (HBV)/HDV group], 130 (9.5%) hepatitis C virus (HCV) (group HBV/HCV), 6 (0.4%) human immunodeficiency virus (HIV) (group HBV/HIV), 138 (10.2%) alcohol abuse (group HBV/alcohol); 109 (8.0%) subjects had at least two cofactors and 924 were in the cofactor-free (CF) group. RESULTS: Compared with patients in group CF those in group HBV/alcohol were older and more frequently had ci…

Serum BLyS/BAFF predicts the outcome of acute hepatitis C virus infection.

2009

Summary.  B-lymphocyte stimulator/B activating factor (BLyS/BAFF) is a tumour necrosis factor-family cytokine that plays a key role in generating and maintaining the mature B-cell pool. BLyS/BAFF expression by macrophages is stimulated by interferon-γ and interleukin-10, and its serum levels are increased in chronic hepatitis C (CHC). The aim of this study was to assess serum levels of BLyS/BAFF in patients with acute hepatitis C (AHC) and correlate them with disease outcome. We studied 28 patients with AHC (14 males, mean age 59.3 ± 15 years), followed for at least 7 months since onset, comparing them with 86 CHC patients and 25 healthy blood donors (HBD). BLyS/BAFF levels were assessed at…

Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.

2009

The correlation between liver stiffness, measured by transient elastography, liver fibrosis, using the histological METAVIR score, and iron overload, measured by atomic absorption spectrometry was evaluated in 56 homozygous-beta-thalassaemics. Liver stiffness increased proportionally to liver fibrosis staging (r = 0.70; P > 0.001) independently of liver iron concentration (r = 0.01; P = 0.932). The area under the receiver-operating characteristic curve for prediction of cirrhosis was 0.997 (95% confidence interval [CI]: 0.925-1.000) with cut-off of 13 kPa with 100% sensitivity (95% CI: 69.0-100.0) and 95% specificity (95% CI: 84.2-99.3). Transient elastography is a reliable non-invasive too…

2017

Background: Gender differences in chronic liver disease (CLD) have been partially investigated. To extend the present knowledge, we evaluated 12,263 patients with CLD enrolled in two national surveys (9997 in 2001 and 2557 in 2014). Methods: The two surveys prospectively recruited patients aged ≥ 18 referring to Italian liver units throughout the country using a similar clinical approach and analytical methods. Results: The overall male to female ratio (M/F) was 1.4 (7138/5124). Compared with females, males were significantly more likely to be younger (52.9 vs. 58.7 yrs.), with HBV infection alone (13.2% vs. 9.2%) and with alcoholic liver disease alone (11.4% vs. 6.9%), but less likely t…

Combined treatment of relapse of chronic hepatitis C with high-dose α2b interferon plus ribavirin for 6 or 12 months

2000

Abstract Background/Aims: Retreatment of relapses of chronic hepatitis C with a standard regimen of interferon plus ribavirin for 6 months obtains a sustained response in a minority of patients with high viraemia and genotype 1b . We aimed to assess whether increasing the interferon dose and prolonging the time of combined treatment may enhance the effectiveness, and also to evaluate the tolerability, and to identify the determinants of sustained response. Methods: Fifty subjects with chronic hepatitis C who had relapsed after one or more courses of α-interferon monotherapy were randomised to receive α 2 b interferon (6 MU tiw) plus ribavirin (1000–1200 mg daily) for 6 or 12 months. ALT nor…

B lymphocyte intestinal homing in inflammatory bowel disease.

2011

Abstract Background Inflammatory bowel disease (IBD) is thought to be due to an abnormal interaction between the host immune system and commensal microflora. Within the intestinal immune system, B cells produce physiologically natural antibodies but pathologically atypical anti-neutrophil antibodies (xANCAs) are frequently observed in patients with IBD. The objective is to investigate the localisation of immunoglobulin-producing cells (IPCs) in samples of inflamed intestinal tissue taken from patients with IBD, and their possible relationship with clinical features. Methods The IPCs in small intestinal, colonic and rectal biopsy specimens of patients with IBD were analysed by means of immun…

Critical reappraisal of risk factors for occurrence of hepatocellular carcinoma in patients with hepatitis C virus.

2011

More than one and half of current cases of hepatocellular carcinoma in the US, Europe, and Japan are attributable to hepatitis C virus (HCV) infection. HCV is also the primary cause of death in patients with HCV-related cirrhosis, with annual incidences of 0.5%-5% in Europe and 4%-10% in Asia. Screening is based on serum alpha-fetoprotein determination and liver ultrasound scan, but the sensitivity of the former is far less than optimal, and screening intervals are still poorly defined for the latter. Risk factors related to the host or environment, or both, appear to be more relevant than viral factors, such as HCV genotype, in determining disease progression to cirrhosis and cancer, and i…

Small bowel angiodysplasia associated with von Willebrand's disease: report of a case.

2006

The association between angiodysplasia (AD) and von Willebrand's disease (vWD) was first described by Quick in 1967. The clinical course of patients with vWD and AD is characterized by multiple admissions to hospital for gastrointestinal bleeding, necessitating transfusions of packed red cells, factor VIII, and von Willebrand factor concentrates. The therapeutic management of these patients is difficult. Both medical and endoscopic techniques have been tried, but no treatment modality has been completely successful. We describe the clinical course of a patient affected by vWD, who suffered repeated massive gastrointestinal bleeding caused by small bowel AD. Intestinal resection was the only…

Abstract Background. Patients with chronic hepatitis C infected by hepatitis A virus have a substantial risk of fulminant hepatitis or death, while the course of hepatitis A virus is uncomplicated in most subjects with chronic hepatitis B. Aim. To evaluate the prevalence of anti-hepatitis A virus antibodies and the incidence of hepatitis A virus seroconversion in a nationwide sample of 530 patients with chronic hepatitis B and/or hepatitis C infection initially susceptible to this infection after a follow-up of some years. Results. The overall anti-hepatitis A virus prevalence was 85.7%, with no difference between males and females. By the age of 50 years, almost all patients were found to …

Granular cell tumor of stomach: a case report and review of literature.

2006

Granular cell tumor (GCT) was described for the first time by Abrikosoff in 1926. It is a relatively rare neoplasm that may occur at many sites, but most commonly in the skin or soft tissues. The occurrence of GCT in the gastrointestinal tract is rare, accounting approximately for 8% of all tumors, among which the most common site is the esophagus, whereas gastric localization is very rare. Gastric GCTs can be solitary or, more frequently, associated with other gastrointestinal localization. Although GCTs are usually clinically and histologically benign, some malignant cases have been reported. Histologically, these tumors consist of polygonal and fusiform cells disposed in compact "nests" …

N-Acetylcysteine for Preventing Acetaminophen-Induced Liver Injury: A Comprehensive Review.

2022

Aims: N-Acetylcysteine (NAC) is used as an antidote in acetaminophen (APAP) overdose to prevent and mitigate drug-induced liver injury (DILI). Our objective was to systematically review evidence of the use of NAC as a therapeutic option for APAP overdose and APAP-related DILI in order to define the optimal treatment schedule and timing to start treatment.Methods: Bibliographic databases (PubMed, Web of Science, Embase, and MEDLINE) were searched for retrospective and prospective cohort studies, case series, and clinical trials. The prespecified primary outcomes were DILI-related mortality, hepatotoxicity, and adverse events (AEs).Results: In total, 34 studies of NAC usage in APAP-related DI…

Unusual B cell morphology in inflammatory bowel disease.

2012

B lymphocytes express various different types of surface immunoglobulins that are largely unrelated to other hematological lines, although some reports have described a relationship between malignant B cells and other cells such as macrophages. Multiple genes of hematopoietic lineage, including transcription factors, are co-expressed in hematopoietic stem cells and progenitors, a phenomenon referred to as "lineage priming". Changes in the expression levels and timing of transcription factors can induce the lineage conversion of committed cells, which indicates that the regulation of transcription factors might be particularly critical for maintaining hierarchical hematopoietic development. …

Peg-interferon alone or combined with ribavirin in HCV cirrhosis with portal hypertension:a randomized controlled trial

2007

Abstract BACKGROUND/AIMS: Risks and benefits of antiviral therapy in HCV cirrhosis with portal hypertension are poorly known. METHODS: We performed a randomized controlled trial in 102 HCV patients with compensated cirrhosis and portal hypertension: 51 received 1 microg/kg/week of Pegylated-interferon alpha-2b and 51 Pegylated-interferon plus 800 mg/day of ribavirin up to 52 weeks. RESULTS: By intention-to-treat analysis, five patients on monotherapy and eleven on combination therapy achieved a sustained virological response (9.8% vs. 21.6%, p=0.06). The response was more frequent for genotypes 2 or 3 than genotype 1 (66.6% vs. 11.3%, p=0.001). Genotype 1, who had low viral load at start of…

Sustained virologic response prevents the development of esophageal varices in compensated, Child-Pugh class A hepatitis C virus-induced cirrhosis. A…

2010

The incidence of de novo development of esophageal varices (EV) in patients with compensated liver cirrhosis has been determined by few studies in the short term and never in the long term. The aims of the present study were to determine the incidence and the risk factors associated with the development of EV and to assess whether antiviral treatment and achievement of sustained virologic response (SVR) may prevent de novo EV development in patients with HCV-induced cirrhosis. We studied 218 patients with compensated EV-free, HCV-induced cirrhosis consecutively enrolled between 1989 and 1992 at three referral centers in Milan, Italy. Endoscopic surveillance was performed at 3-year intervals…

A performance evaluation of the expert system 'Jaundice' in comparison with that of three hepatologists.

1991

The diagnostic performance of an Expert System (Jaundice) designed to discriminate between different causes of jaundice was evaluated in a test sample of 200 consecutive in-patients with serum bilirubin greater than or equal to 51 mumol/l. The average probability assigned to true diagnosis, the non-error rate and the overall accuracy were, respectively, 55%, 77% and 70%. The Expert System's discriminatory ability in probabilistic prediction, assessed by a method based on continuous functions of the diagnostic probabilities (Brier score) was good. We also compared the ability of our Expert System to that of three experienced hepatologists, who were required to give a diagnosis in 20 cases fo…

Necrotizing Soft Tissue Fasciitis after Intramuscular Injection

2018

Necrotizing soft tissue fasciitis (NSTIs) or necrotizing fasciitis is an infrequent and serious infection. Herein, we describe the clinical course of a female patient who received a diagnosis of NSTIs after gluteus intramuscular injection. We also report the results of our review of published papers from 1997 to 2017. Since now, 19 cases of NSTIs following intramuscular injections have been described. We focus on the correlation between intramuscular injection and NSTIs onset, especially in immunosuppressed patients treated with corticosteroids, suffering from chronic diseases or drug addicted. Intramuscular injections can provoke severe tissue trauma, representing local portal of infection…

Inguinal hernioplasty improves the quality of life in patients with cirrhosis.

2008

Abstract Background The optimal management of symptomatic inguinal hernia (SIH) in cirrhotics is still undefined. Both hernia and cirrhosis impair quality of life (QOL). The aim of this study was to evaluate QOL by a Short Form-36 (SF-36) questionnaire in cirrhotic patients undergoing inguinal hernioplasty. Methods Thirty-two cirrhotic patients undergoing inguinal hernioplasty were evaluated. They were classified according to Child's class and to the absence or presence of refractory ascites. The SF-36 questionnaire was administered the day before and 6 months after surgery. Global analyses of the 8 domains of SF-36 and of 2 comprehensive indexes of SF-36, Physical Component Summary (PCS) a…

IL-10 and TNF-α polymorphisms and the recovery from HCV infection

2003

Hepatitis C virus (HCV) infection becomes chronic in about 85% of infected individuals, whereas only 15% of infected people clear spontaneously the virus. It is conceivable that the host immunogenetic background influences the course of infection in term of recovery. Thus, in this study we have evaluated the effect of functionally relevant polymorphisms at tumor necrosis factor-alpha (TNF-alpha, i.e., 2 biallelic polymorphisms at nt -863 and nt-308 of the promoter) and interleukin-10 (IL-10) loci (i.e., 1 biallelic polymorphism at nt -1082 of the promoter), on the clearance of HCV infection. To this purpose, we compared 18 Sicilian patients who had spontaneously recovered from previous HCV …

Risk of cirrhosis-related complications in patients with advanced fibrosis following hepatitis C virus eradication

2017

Background &amp; Aims: The risk of hepatocellular carcinoma (HCC) is reduced but not eradicated among patients with hepatitis C virus (HCV)-induced advanced hepatic fibrosis who attained sustained viral response (SVR). We aimed to assess the risk of cirrhosis-related complications in this specific group of patients. Methods: Data from previously reported Western cohort studies including patients with chronic HCV infection and bridging fibrosis or cirrhosis who attained SVR were pooled for survival analyses on the individual patient level. The primary endpoint was HCC and the secondary endpoint was clinical disease progression, defined as liver failure, HCC or death. Results: Included were 1…

Anti-tissue transglutaminase antibodies in patients with abnormal liver tests: is it always coeliac disease?

2005

Coeliac disease (CD) is found in 5-10% of patients with chronically abnormal liver tests and no obvious cause of liver disease. In this population the efficacy of screening for CD by anti-tissue transglutaminase (anti-tTG) may be impaired by the high rate of positive anti-tTG found in chronic liver disease.To evaluate the prevalence of coeliac disease and the role of anti-tTG in patients with non-viral, non-autoimmune chronic and no obvious cause of liver damage.Out of 2,512 consecutive patients with abnormal liver tests, 168 (118 men, 50 women; mean age 40.7 +/- 12.6 years) were defined, on the basis of clinical data and liver biopsy, as NAFLD or cryptogenic chronic hepatitis. All were tes…

Pegylated-interferon-α(2a) in clinical practice: how to manage patients suffering from side effects

2011

Introduction: The goal of antiviral therapy in patients with chronic hepatitis C is to slow or halt the progression of fibrosis and prevent the development of cirrhosis. Accordingly, antiviral treatment is proposed for a large population of patients with chronic hepatitis. Areas covered: The standard-of-care for chronic hepatitis C is the combination of pegylated IFN (PEG-IFN) and ribavirin. The use of these drugs has been correlated with a range of adverse effects, including influenza-like symptoms, hematological changes and neuropsychiatric disturbances. The effects of these adverse events associated with PEG-IFN therapy are manifold and are a major reason why patients decline or stop the…

2017

Background There is a need for hepatitis C virus (HCV) therapies with excellent efficacy across genotypes and in diverse populations. Part A of the C-CREST-1 and C-CREST-2 trials led to the selection of a three-drug regimen of grazoprevir (MK-5172; an HCV NS3/4A protease inhibitor; 100 mg/day) plus ruzasvir (MK-8408; an NS5A inhibitor; 60 mg/day) plus uprifosbuvir (MK-3682; an HCV NS5B polymerase inhibitor; 450 mg/day). Part B of the studies tested this combination as a single formulation in different treatment durations in a broader population. Methods Part B of these randomised, phase 2, open-label clinical trials enrolled individuals from 15 countries who were chronically infected with H…

Long-term course of interferon-treated chronic hepatitis C

1998

Abstract Background/Aims: To evaluate whether sustained response to α-interferon improves clinical outcome in patients with chronic hepatitis C. Methods: A cohort of 410 consecutive patients (65% with chronic hepatitis, 35% with cirrhosis) were treated with α-interferon in two trials (mean follow-up 62.1 months, range 7–109 months). All were serum HCV RNA positive before therapy and received first 10 then 5 million units of α-2b or α-n1 interferon three times weekly for 6 to 12 months. Sustained response was defined as normal aminotransferases 12 months after stopping interferon. Results: Sixty-two patients (15.1%: 54 with chronic hepatitis, eight with cirrhosis) were sustained responders. …

Hepatitis C Viremia in Chronic Liver Disease: Relationship to Interferon-α or Corticosteroid Treatment

1994

We assessed the pattern of hepatitis C viremia in chronic liver disease by studying 100 hepatitis C virus antibody–positive patients: 48 with chronic hepatitis, 21 with cirrhosis and 31 with hepatocellular carcinoma and cirrhosis. Serum hepatitis C virus RNA was detected by means of both the conventional nested polymerase chain reaction and a newly developed assay based on branched DNA that can also quantify viremia. Hepatitis C virus RNA was found in 94 of 100 patients with polymerase chain reaction and in 71 of 100 patients with branched-DNA (p < 0.001). Mean viremia level (× 103 genome equivalents/ml ± S.D.), as assessed with the branched-DNA test, was 5,700 ± 7,618 in the 48 patients wi…

HAV infection in chronic liver disease: a rationale for vaccination.

2003

We report the conduct and results of a systematic search of the literature to assess whether exposure to HAV could induce a fatal deterioration of liver diseases. We assessed 30 studies and found evidence of progressive decrease of natural immunity against HAV in Italy. HAV vaccine seems as safe in chronic liver diseases than in general population. On the basis of the evidence we recommend that subjects with chronic liver disease should be vaccinated against HAV, especially if younger than 40 years.

A randomized controlled trial of high-dose maintenance interferon therapy in chronic hepatitis C

1997

In chronic hepatitis C virus (HCV) infection, the rate of sustained response to interferon is low. We evaluated, in patients responding to a 26-week course of interferon, the effect of high-dose maintenance therapy in preventing relapse. Three hundred and ten patients with chronic HCV infection (38.3% with cirrhosis, 80.6% with HCV type 1) received interferon alfa-2b for 26 weeks (10 MU tiw for 8 weeks, then 5 MU tiw for 18 weeks). One hundred and twenty-four subjects (40%) normalized aminotransferases, and were allocated randomly either to continue on 5 MU tiw for a further 26 weeks (prolonged therapy group: 60 patients) or to stop interferon (brief therapy group: 64 patients). Fifty-two w…

Significance of serum Il-9 levels in inflammatory bowel disease

2015

IL-9, which may be an inflammatory or regulatory cytokine, can be experimentally produced in a Th17 or modified Th2 context in the presence of T cell receptor (TCR) stimulation. The primary aim of this study was to measure serum IL-9 levels in patients with inflammatory bowel disease (IBD), and evaluate their relationships with the patients’ clinical characteristics. The secondary aim was to determine the levels of interferon-γ (IFN (interferon)-γ), Th2 cytokines (IL-4, IL-5 and IL-13), and IL-6 in order to clarify the context of detectable peripheral cytokines in which IL-9 is produced. Venous blood samples of 43 IBD patients (20 with Crohn’s disease [CD] and 23 with ulcerative colitis [U…

Predictive factors of polycystic ovary syndrome in girls with precocious pubarche

2021

Objective: The aim of this study is to clarify, in girls with premature pubarche (PP), the influence of premature androgenization on the prevalence of polycystic ovary syndrome (PCOS). Design and patients: Ninety-nine PP girls, 63 who developed PCOS and 36 who did not develop PCOS, were retrospectively included. Clinical, anthropometric, and metabolic parameters were evaluated at the time of diagnosis of PP and after 10 years from menarche to find predictive factors of PCOS. Results: Young females with PP showed a PCOS prevalence of 64% and showed a higher prevalence of familial history of diabetes (P = 0.004) and a lower prevalence of underweight (P = 0.025) than PP-NO-PCOS. In addition, g…

Occurrence of hepatocellular carcinoma and decompensation in western european patients with cirrhosis type B

1995

To examine the morbidity of compensated cirrhosis type B, a cohort of 349 Western European, white patients (86% men; mean age, 44 years) with biopsy-proven cirrhosis was followed up for a mean period of 73 months and was studied for occurrence of hepatocellular carcinoma (HCC) and decompensation. At entry into the study all patients were tested for hepatitis B e antigen (HBeAg; 34% of patients were HBeAg-positive) and antibody to hepatitis delta virus (anti-HDV; 20% of patients were anti-HDV-positive); 48% of 252 patients tested were hepatitis B virus (HBV)-DNA-positive. During follow-up HCC developed in 32 (9%) of the 349 patients and decompensation was observed in 88 (28%) of 317 tumor-fr…

Clinical course and management of acute and chronic viral hepatitis during pregnancy.

2014

Summary Pregnancy is a para-physiologic condition, which usually evolves without any complications in the majority of women, even if in some circumstances moderate or severe clinical problems can also occur. Among complications occurring during the second and the third trimester very important are those considered as concurrent to pregnancy such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, HELLP syndrome and acute fatty liver of pregnancy. The liver diseases concurrent to pregnancy typically occur at specific times during the gestation and they may lead to significant maternal and foetal morbidity and mortality. Commonly, delivery of the foetus, even preterm, usually te…

The impact of insulin resistance, serum adipocytokines and visceral obesity on steatosis and fibrosis in patients with chronic hepatitis C

2007

SUMMARY Aims  To assess whether host metabolic factors influence the degree of hepatic steatosis and fibrosis in patients infected with hepatitis C virus, and to evaluate the impact of anti-viral therapy on insulin resistance and serum levels of adipocytokines. Methods  Clinical and biochemical features, anthropometrical characteristics, and levels of fasting insulin, leptin, adiponectin and resistin were measured in ‘naive’ patients with chronic hepatitis C, before, during and after therapy with Peg-Interferon-alpha 2a plus Ribavirin. Results  Forty-eight patients were included (M/F 28/20; mean age 50.0 ± 12.6 years; 62.5% genotype-1). Body mass index was 26.4 ± 4.0 kg/m2, and visceral obe…

Hepatitis B vaccination of relatives of hepatitis B virus DNA positive carriers: an experience with plasma-derived vaccine.

1989

We assessed in a western population the efficacy of a plasma-derived hepatitis B vaccine in relatives of highly infectious hepatitis B virus (HBV) carriers. A consecutive group of 103 HbsAg, anti-HBs and anti-HBc negative household relatives of 45 HBV-DNA positive chronic carriers received a 5 micrograms dose of plasma-derived vaccine at 0, 1, 2 and 12 months. Protective levels of immunity developed in 101 subjects (97.8%) 3 months after boosting. Low responders to the vaccine were mostly found among parents and spouses of carriers, whilst offspring and siblings were usually high responders. The main discriminant in predicting a good response was age below 12 years. Hyporesponsiveness did n…

Hepatitis C virus infection and global kidney health: the consensus proceedings of the International Federation of Kidney Foundations

2020

Hepatitis C virus (HCV) infection is an important cause of major morbidities including chronic liver disease, liver cancer, and acute kidney injury (AKI) as well as chronic kidney disease (CKD). HCV can affect kidney health; among CKD and AKI patients with HCV infection, the clinical outcomes are worse. The prevalence of HCV infection is exceptionally high among dialysis and kidney transplant patients throughout the globe. It is estimated that 5% to 25% or more of dialysis dependent patients are affected by chronic HCV, based on the region of the world. Almost half of all deaths in CKD patients, including HCV-infected patients, are due to cardiovascular disease, and HCV infected patients ha…

HCV genotypes in Sicily: is there any evidence of a shift?

2009

The distribution of HCV strains in any area is characterized by a relative prevalence of one genotype, and a number of less prevalent types. In some Western countries a change from the prevalent HCV genotype 1 to genotypes 3 and 4 has been reported in the last decade. In order to assess possible variations of the distribution of HCV genotypes in Sicily, a southern region of Italy, a hospital-based cohort, collected prospectively, of 3,209 subjects with chronic HCV infection was surveyed, comparing the distribution of HCV genotypes during two consecutive periods, from 1997 to 2002 and from 2003 to 2007, according to age and gender. The results show that genotype 1b, which has been historical…

Acute polymyositis during treatment of acute hepatitis C with pegylated interferon alpha-2b.

2005

Hepatitis C virus is not cleared after primary infection in 50-85% of subjects exposed to hepatitis C virus. Anti-viral treatment during the early phase of infection significantly enhances the likelihood of a sustained clearance of hepatitis C virus. Although, a variety of autoimmune-related side effects have been observed during interferon therapy for chronic hepatitis, immuno-mediated adverse reactions have not been reported during treatment of acute hepatitis C. We describe the case of a patient who developed acute hepatitis C virus infection and, while receiving pegylated interferon alpha-2b monotherapy, developed a severe polymyositis. This case illustrates the potential risk of autoim…

Morphological distribution of μ chains and cd15 receptors in colorectal polyp and adenocarcinoma specimens

2013

BACKGROUND: We have recently investigated the localisation of immunoglobulin-producing cells (IPCs) in inflamed intestinal tissue samples from patients with inflammatory bowel disease (IBD), and identified two main patterns of B lymphocyte infiltration: one characterised by the moderate strong stromal localisation of small B1 cell-like IgM+/CD79+/CD20-/CD21-/CD23-/CD5 ± IPCs, and the other by the peri-glandular localisation of IPCs with irregular nuclei that had surface markers specific for a B cell subset (IgM and CD79), but quantitative differences in their λ and κ chains. The same patients were also tested for CD15+ receptors, which were localised on inflammatory cell surfaces or in the …

HCV E1E 2‐ MF 59 vaccine in chronic hepatitis C patients treated with PEG ‐ IFN α2a and R ibavirin: a randomized controlled trial

2013

Hepatitis C virus (HCV) vaccines may be able to increase viral clearance in combination with antiviral therapy. We analysed viral dynamics and HCV-specific immune response during retreatment for experienced patients in a phase Ib study with E1E2MF59 vaccine. Seventy-eight genotype 1a/1b patients [relapsers (30), partial responders (16) and nonresponders (32) to interferon-(IFN)/ribavirin-(RBV)] were randomly assigned to vaccine (V:23), Peg-IFNα2a-180-ug/qw and ribavirin 1000-1200-mg/qd for 48 weeks (P/R:25), or their combination (P/R + V:30). Vaccine (100 μg/0.5 mL) was administered intramuscularly at week 0-4-8-12-24-28-32-36. Neutralizing of binding (NOB) antibodies and lymphocyte prolife…

Characteristics and Changes over Time of Alcohol-Related Chronic Liver Diseases in Italy

2018

Introduction. To evaluate the characteristics of alcohol-related chronic liver disease (CLD) in Italy and their potential changes over time. Patients and Methods. Subjects with CLD were enrolled in two national surveys performed in 2001 and in 2014 in Italy. The two surveys prospectively recruited patients aged ≥ 18 years referring to more than 80 Italian liver units scattered all over the country using similar clinical approach, analytical methods, and threshold of risky alcohol intake definition (≥ 3 units/day in men and ≥ 2 units/day in women). Results. Out of 12,256 enrolled subjects, 2,717 (22.2%) reported a risky alcohol intake. Of them, anti-HCV positive was observed in 48.3% of subj…

The Impact of Antiviral Therapy and the Influence of Metabolic Cofactors on the Outcome of Chronic HCV Infection

2010

Natural history of HCV related chronic hepatitis is influenced and modified by many factors: virus features, coinfections and host characteristics. In particular, a peculiar genetic background of the host by conditioning the occurrence of intracellular metabolic derangements (i.e., insulin resistance) might contribute to accelerate the rate of progression to cirrhosis and eventually the occurrence of hepatocellular carcinoma (HCC) and death. Likely, direct interplays between virus genotype and host genetic background might be hypothesized at this level. Morbidity and mortality in cirrhosis is primarily associated with complications of liver cirrhosis (ascites, hepatic encephalopathy, jaundi…

Weight-based dosing: Which impact on efficacy and safety of therapy?

2004

Abstract Pegylated interferons (PEG-IFNs) in combination with ribavirin represent the most recent advance in the treatment of patients withchronic hepatitis C (CHC): two large clinical trials have shown a superior efficacy in clearing HCV in almost 60% of treated naive patients. Responses to antiviral treatment of CHC vary according to both viral and host factors. Managing patients with CHC infection requires individualised treatment strategies to optimise outcomes. Several landmark publications on PEG-IFNs have reported that weight is a significant predictive factor for SVR in the treatment of CHC with fixed-dose drug administration. With fixed-dose treatment, there is a direct correlation…

Efficacy of the treatment with prostaglandin E-1 in venous ulcers of the lower limbs.

2005

Background. Venous ulcers represent an important medical problem due to their high prevalence and consequent sanitary costs. In this study we evaluated the effect of Prostaglandin E-1 (PGE-1), a drug that improves district ischemia, on the healing of venous ulcers. Methods. We performed a randomized, placebo-controlled, single blind study, in which 87 patients, carriers of venous leg ulcers, homogeneous for dimensions and characteristics, were treated for 20 days an with infusion of Prostaglandin E-1 or placebo, in association with a topic therapy. The dimension and the number of the ulcers were determined at the beginning of the treatment and then every 20 days up to 4 months or until tota…

Predicting Mortality Risk in Patients With Compensated HCV-Induced Cirrhosis: A Long-Term Prospective Study

2009

OBJECTIVES: The identification of prognostic factors associated with mortality is crucial in any clinical setting. METHODS: We enrolled in a prospective study 352 patients with compensated hepatitis C virus (HCV)-induced cirrhosis, consecutively observed between 1989 and 1992. At entry, patients underwent upper endoscopy to detect esophageal varices, and were then surveilled by serial clinical and ultrasonographic examination. The model for end-stage liver disease (MELD) score was calculated with information collected at enrollment. Baseline predictors and intercurrent events associated with mortality were assessed using the Cox regression model. RESULTS: During a median follow-up of 14.4 y…

Influence of universal HBV vaccination on chronic HBV infection in Italy: Results of a cross-sectional multicenter study

2017

Background and Aim The universal hepatitis B vaccination for infants and 12-year-old adolescents (the latter limited to the first 12 years of application) was launched in Italy in 1991. Twenty-three years later we evaluated the impact of the vaccination campaign on the burden of HBsAg-positive chronic liver diseases (CLD). Material and Methods 513 HBsAg-positive chronic carriers referring to 16 Italian liver units were investigated and compared with HBsAg carriers enrolled in previous surveys. Results The proportion of inactive carriers decreased from 20.0% in 2001 to 3.3% in 2014, while that of cirrhotic patients increased from 22.6 to 33.2%. Regarding the age class 0–33 (fully covered by …

Management of hepatitis C virus genotype 4: recommendations of an international expert panel.

2011

HCV has been classified into no fewer than six major genotypes and a series of subtypes. Each HCV genotype is unique with respect to its nucleotide sequence, geographic distribution, and response to therapy. Genotypes 1, 2, and 3 are common throughout North America and Europe. HCV genotype 4 (HCV-4) is common in the Middle East and in Africa, where it is responsible for more than 80% of HCV infections. It has recently spread to several European countries. HCV-4 is considered a major cause of chronic hepatitis, cirrhosis, hepatocellular carcinoma, and liver transplantation in these regions. Although HCV-4 is the cause of approximately 20% of the 170 million cases of chronic hepatitis C in th…
