Clinical experience with different pegylated interferons: Is there a difference?

2009

Abstract The acute phase of hepatitis C virus (HCV) infection represents a key point in the evolution of hepatitis C. The infection either resolves spontaneously, or progresses into chronic disease. However, the asymptomatic nature of acute hepatitis C contributes to difficulties in detection, diagnosis and hence, the assessment of therapy when indicated. Controversies in chronic HCV related to the implications of both selected predictors of treatment outcome and clinical experience with structurally different Peg-IFNs are discussed.

Assessment of human cytomegalovirus specific T cell immunity in human immunodeficiency virus infected patients in different disease stages following …

2004

T cell immunity to human cytomegalovirus (HCMV) was assessed in HAART-treated HIV-1 infected patients (9 asymptomatic, CDC group A; and 22 symptomatic, CDC group B), and in eight HIV-1 long term non-progressors. Patients were either prospectively or cross-sectionally examined for CD4(+) T cell counts, HIV RNA load, HCMV leukoDNAemia, HCMV DNA in urine, lymphoproliferative response (LPR) to HCMV and phytohemagglutinin (PHA), and cytokine secretion (IFN-gamma and IL-4) by HCMV-stimulated peripheral blood mononuclear cell (PBMC) cultures. No patient either progressed to clinical AIDS or developed HCMV active infection during the study period. Twenty-nine patients responded to HAART, though 12 …

Lack of association between the kinetics of human cytomegalovirus (HCMV) glycoprotein B (gB)-specific and neutralizing serum antibodies and developme…

2001

The kinetics of the gB-specific and neutralizing antibody responses to human cytomegalovirus (HCMV) were analyzed in 26 allogeneic stem-cell transplant recipients who either did (n = 20) or did not (n = 6) develop asymptomatic HCMV active infection during the study period. Antibody response profiles varied widely among individuals in both groups, irrespective of whether HCMV active infection did or did not occur. Development of HCMV active infection was not preceded by a decline in functional serum antibody levels. Neither the absence nor the presence of HCMV active infection correlated with either high or low serum levels of gB-specific and neutralizing antibodies, respectively. In most pa…

Molte Palermo. Temi

2019

Nel tema delle incompiute idee di città possibili si riconoscerà il paradigma connotativo dello stesso divenire di Palermo, lungo un percorso millenario di processi di trasformazione nessuno dei quali portato a compimento, in virtù di quel valore distintivo di exemplum che non necessita di ulteriori e conclusive dimostrazioni. Il corso della storia, del resto, ha imposto a Palermo il ciclico riproporsi di destini interrotti. Tale si rilevò l’invenzione della città capitale, quella della “quadratura geometrica e della croce di strade” sovrimpressa a quella archetipica e fondativa della Pan-ormos scambiatrice. E l’incompiutezza sarà il tratto distintivo della città dei rettifili stradali otto…

CFTR p.Arg117His associated with CBAVD and other CFTR-related disorders

2013

International audience; BACKGROUND:The high frequency of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene mutation p.Arg117His in patients with congenital bilateral absence of the vas deferens (CBAVD) and in newborns screened for CF has created a dilemma.METHODS:Phenotypic and genotypic data were retrospectively collected in 179 non-newborn French individuals carrying p.Arg117His and a second CFTR mutation referred for symptoms or family history, by all French molecular genetics laboratories, referring physicians, CF care centres and infertility clinics.RESULTS:97% of the patients had the intronic T7 normal variant in cis with p.Arg117His. 89% patients were male, wit…

Gluten-free diet impact on leptin levels in asymptomatic coeliac adolescents: one year of follow-up.

2006

Coeliac disease, daily more frequently diagnosed in our population, involves many organs also in oligosymptomatic patients and with an adequate nutritional regime. Possible endocrine implications include failure to thrive, pubertal delay and reproduction diseases due to deregulation of GH, FSH and LH secretion. Leptin, an adipose tissue hormone, can be decreased as well and its deficiency could be related to growth and puberty anomalies. We studied 14 asymptomatic coeliac patients in peripubertal age (7.5–13.8 years) and tested their leptin levels in order to correlate them with endocrine and anthropometric data. Before the diet was started leptinaemia (M±DS) was: 4.94 ± 5.53 ng/ml. In 10/1…

Oesophagogastroduodenoscopy in patients with cirrhosis: Extending the range of detection beyond portal hypertension

2010

Background: Oesophagogastroduodenoscopy is currently recommended for the screening of varices in cirrhosis. In addition to the assessment of varices, oesophagogastroduodenoscopy can detect conditions that, while unrelated to portal hypertension, may require treatment. Aims: We evaluated in a large cohort of cirrhotic patients the prevalence of upper digestive findings other than oesophagogastric varices, the associations between upper gastrointestinal findings, portal hypertension and features of cirrhosis, and the incidence of new lesions in the course of a surveillance program. Methods: Analysis of the records of 611 consecutive cirrhotic patients undergoing oesophagogastroduodenoscopy fo…

Estimated prevalence of undiagnosed HCV infected individuals in Italy: A mathematical model by route of transmission and fibrosis progression

2021

Abstract Background The universal treatment of diagnosed patients with chronic HCV infection has been widely conducted in Italy since 2017. However, the pool of individuals diagnosed but yet to be treated in Italy has been estimated to end around 2025, leaving a significant proportion of infected individuals undiagnosed/without care. Estimates of this population are currently unknown. Methods A probabilistic modelling approach was applied to estimate annual historical HCV incident cases by their age-group (0–100 years) distribution from available literature and Italian National database (1952 to October 2019). Viraemic infection rates were modelled on the main infection routes in Italy: peo…

Population screening for liver fibrosis: Toward early diagnosis and intervention for chronic liver diseases

2022

Population screening; Liver fibrosis; Early diagnosis Cribratge de població; Fibrosi hepàtica; Diagnòstic precoç Cribado de población; Fibrosis hepática; Diagnóstico precoz Cirrhosis, highly prevalent worldwide, develops after years of hepatic inflammation triggering progressive fibrosis. Currently, the main etiologies of cirrhosis are non-alcoholic fatty liver disease and alcohol-related liver disease, although chronic hepatitis B and C infections are still major etiological factors in some areas of the world. Recent studies have shown that liver fibrosis can be assessed with relatively high accuracy noninvasively by serological tests, transient elastography, and radiological methods. Thes…
