Abstract Background Migrants, mainly undocumented and low-income refugees, are at high risk of hepatitis C virus (HCV) infection, but are a difficult-to-reach and to-treat population. The aim of the study was to evaluate the effectiveness of a test and treat model with direct-acting antiviral for HCV infection in these migrants coming from low-income and living in southern Italy. Methods A prospective, multicenter, collaborative study based on a four-phase-program (educational counseling, screening, linkage-to-care and treatment) was designed in southern Italy; the study started in June 2018, was stopped in February 2020 because of the outbreak of SARS-CoV2 infection in Italy and was resumed in February 2021 until November 2021. After educational counseling on infectious diseases that are transmitted through blood or sexually pseudonymized HCV screening was offered to all undocumented migrants and low-income refugees observed at one of the 1st level clinical centers. The HCV-RNA-positive subjects were referred to one of the 3rd level units of Infectious Diseases (ID) and treated with a 12-week course of sofosbuvir-velpatasvir and observed for 12 weeks after the end of direct antiviral agents (DAA) treatment. Statistical analysis For the descriptive analysis, the categorical variables were reported as absolute numbers and relative frequencies. Continuous variables were summarized as mean and standard deviation (SD) if normally distributed, or as a median and interquartile range (IQR) if not normally distributed. We used Pearson chi-square or Fisher’s exact test for categorical variables and Student’s t test or Mann–Whitney test for continuous variables. A P value

Background and Aims: We aimed to characterize the epidemiologic and comorbidities profiles of patients with chronic Hepatitis D (CHD) followed in clinical practice in Italy and explored their interferon (IFN) eligibility. Methods: This was a cross-sectional study of the PITER cohort consisting of consecutive HBsAg-positive patients from 59 centers over the period 2019-2023. Multivariable analysis was performed by logistic regression model. Results: Of 5492 HBsAg-positive enrolled patients, 4152 (75.6%) were screened for HDV, 422 (10.2%) were anti-HDV positive. Compared with HBsAg mono-infected, anti-HDV positive patients were more often younger, non-Italians, with a history of drug use, had elevated alanine transaminase (ALT), cirrhosis, or hepatocellular carcinoma (HCC). Compared with Italians, anti-HDV positive non-Italians were younger (42.2% age ≤ 40 years vs. 2.1%; P < 0.001), more often females (males 43.0% vs. 68.6%; P < 0.001) with less frequent cirrhosis and HCC. HDV-RNA was detected in 63.2% of anti-HDV-positive patients, who were more likely to have elevated ALT, cirrhosis, and HCC. Extrahepatic comorbidities were present in 47.4% of anti-HDV positive patients and could affect the eligibility of IFN-containing therapies in at least 53.0% of patients in care. Conclusions: CHD affects young, foreign-born patients and older Italians, of whom two-thirds had cirrhosis or HCC. Comorbidities were frequent in both Italians and non-Italians and impacted eligibility for IFN.

In the conservation of monumental heritage, the collection and utilization of information are of primary importance. The Heritage Building Information Modeling (HBIM) procedure harnesses the potential of three-dimensional models, offering significant advantages in accessing documentation, interoperability, multidimensionality of intervention design, cost evaluation, and maintenance management. Our attention here is focused on the Certosa di Pisa (Italy), a large historical complex built in the 14th century as a monastery of the Carthusian Order, currently in a state of deterioration and in need of restoration and re-functionalization. The multifaceted nature of this monumental complex, with its intricate interplay of architectural elements spanning different historical periods and featuring diverse techniques, poses a significant challenge for structural safety assessment. This case study presents an opportunity to explore an HBIM approach to streamline the diagnostic process and facilitate the intervention design phase. The goal is achieved by utilizing an accurate 3D model enriched with data from multiple sources and automating certain operations for a simplified safety assessment of masonry structures under both gravity and seismic loads. The usefulness of the HBIM methodology is highlighted as a valuable tool in the realm of cultural heritage structures for both practitioners and scholars alike.

An increasing number of satellite constellations being deployed in orbit fosters the introduction of a more efficient paradigm of distributed, interconnected orbital assets to ensure better resource exploitation in orbit. This paper aims to illustrate through quantitative modeling the effects of satellites on board available resources and inter-satellite telecommunication hypotheses on the overall operations of a federated satellite system network. Key research questions addressed by this work include the performance quantification of a one hundred CubeSats federated satellite system network in terms of network response and data volume exchanged under several onboard resource constraints. The applicability of a federated satellite system to a time-critical disaster response monitoring scenario has also been verified to assess the practical implementation of such a paradigm in reduced inter-satellite communicability conditions. A distributed simulator based on the IEEE 1516–2010 standard is employed to obtain the federated satellite system network topology according to the individual satellite operations to analyze the network performances, exploiting an approach based on the network’s adjacency matrix. Despite reduced communicability, which limits the average inter-satellite link to an 8 bps time-averaged goodput due to poor onboard resources availability, the federated satellite system proves to be an auto-sufficient and decentralized paradigm, capable of responding to a time-critical scenario such as a rapid mapping request after a natural disaster in under 6 hours. As a result, this work provides the foundation for more detailed development of a federate satellite network, compliant with current radiofrequency regulations.

Objectives: The study measures trends in the profile of patients with chronic hepatitis B virus linked to care in Italy. Methods: A cross-sectional, multicenter, observational cohort (PITER cohort) of consecutive patients with hepatitis B surface antigen (HBsAg) over the period 2019-2021 from 46 centers was evaluated. The reference was the MASTER cohort collected over the years 2012-2015. Standard statistical methods were used. Results: The PITER cohort enrolled 4583 patients, of whom 21.8% were non-Italian natives. Compared with those in MASTER, the patients were older and more often female. The prevalence of hepatitis B e antigen (HBeAg) declined (7.2% vs 12.3; P

Background: In the present study we evaluated the efficacy of an innovative model of HCV micro-elimination in a hospital setting in an area of high HCV prevalence. Patients and metods: Between January and December 2019, a prospective, interventional study for a program of HCV case-finding and linkage-to-care was performed in S. Anna and S. Sebastiano hospital of Caserta, in Campania, a region in southern Italy. All adult patients who were admitted to the Caserta hospital in the study period and resulted positive for anti-HCV were included in the study. The outcomes evaluated were the number of subjects resulting HCV-RNA-positive, those linked-to-care and treated with a DAA and the subjects whose anti-HCV-status was unknown. Results: In the study period, 14,396 subjects, admitted to the hospital for different reasons, were tested for anti-HCV: 529 (3.7%) subjects resulted positive for anti-HCV. Of the 529 anti-HCV-positive subjects, 10 died during hospitalization and 243 were already treated with a DAA. The remaining 276 subjects were contacted and agreed to be evaluated. Of these 276 subjects, 68 patients resulted HCV- RNA-negative and 194 HCV-RNA-positive and 180 of these were treated with a DAA according to the international guidelines. Discussion: A simple, rapid, inexpensive model of HCV micro-elimination in the hospital setting allowed us to find anti-HCV-positive subjects with unknown anti-HCV status or not linked to a clinical center.

Abstract SARS-CoV-2 is still a health problem worldwide despite the availability of vaccines. Therefore, there is a need for effective and safe antiviral. SARS-CoV-2 and HCV necessitate RNA-dependent RNA polymerase (RdRp) for replication; therefore, it has been hypothesized that RdRp inhibitors used to treat HCV may be effective treating SARS-CoV-2. Accordingly, we evaluated the effect of the sofosbuvir/velpatasvir (SOF/VEL) combination in early SARS-CoV-2 infection. A multicenter case–control study was conducted, enrolling 120 patients with mild or moderate COVID-19, of whom 30, HCV coinfected or not, received SOF/VEL tablets (400/100 mg) once daily for 9 days within a median of 6 days from the beginning of infection and 90 controls were treated with standard care. The primary endpoint was the effect on viral clearance, and the secondary endpoint was the improvement of clinical outcomes. Nasal swabs for SARS-CoV-2 by PCR were performed every 5–7 days. Between 5–14 days after starting SOF/VEL treatment, SAS-CoV-2 clearance was observed in 83% of patients, while spontaneous clearance in the control was 13% (p

In this study, Marfella et al. show that patients with diabetes and poor glycaemic control have a blunted response to COVID-19 vaccine and are more prone to develop breakthrough infections, with further analysis suggesting smoking and male sex as potential risk factors to get COVID-19 despite vaccination.

Background: The once-daily oral combination of daclatasvir (DCV) and sofosbuvir (SOF), with or without ribavirin (RBV), is effective and well tolerated in patients with hepatitis C virus (HCV). However, further field-practice studies are necessary to investigate the effectiveness and safety of the DCV+SOF combination in diverse subpopulations of patients with HCV, including those who are more challenging to treat such as patients with a genotype 3 (G3) infection. The aim of this retrospective, multicenter, field-practice study was to investigate the therapeutic efficacy and safety of the oral combination of DCV and SOF, with or without RBV (DCV+SOF±RBV), in a large unselected cohort of patients with chronic HCV infection (CHC). Patients and methods: Consecutive patients received DCV+SOF±RBV for 12 or 24 weeks. The efficacy endpoint was sustained virological response at 12 weeks after the end of treatment (SVR12). Safety factors were also considered. Results: A total of 620 patients were included in this study; the predominant genotype was G3 (55.3%). Of the total sample, 248 (40%) patients were treated with DCV+SOF+RBV and 372 (60%) did not receive RBV. The majority of patients assessed at week 12 (98%, 596/608) achieved SVR12. Among G3 patients, 98.8% (335/339) achieved SVR12. The most common adverse event was elevated bilirubin (30.6%), recorded in 4.9% of cases as a grade 3–4 adverse event. Conclusion: This study shows the high pan-genotypic effectiveness and safety of the DCV+SOF±RBV combination in a large, unselected sample of CHC patients with G1–4, including a wide proportion of G3 CHC patients.

Abstract Background Hypertension is the most frequent co-morbidity in patients with covid-19 infection, and we might speculate that a specific blood group could play a key role in the clinical outcome of hypertensive patients with covid-19. Methods In this prospective study, we compared 0 vs. non-0 blood group in hypertensive patients with covid-19 infection. In these patients, we evaluated inflammatory and thrombotic status, cardiac injury, and death events. Results Patients in non-0 (n = 92) vs. 0 blood group (n = 72) had significantly different values of activated pro-thrombin time, D-dimer, and thrombotic indexes as Von Willebrand factor and Factor VIII (p

Background/Aims: Patients with genotype 3 hepatitis C virus (G3-HCV) cirrhosis are very difficult to treat compared to patients with other HCV genotypes. The optimal treatment duration and drug regimen associated with ribavirin (RBV) remain unclear. To evaluate the efficacy and safety of daclatasvir (DCV)/sofosbuvir (SOF) plus a flat dose of 800 mg RBV (flat dose) compared to DCV/SOF without RBV or DCV/SOF plus an RBV dose based on body weight (weight-based) in G3-HCV patients with compensated or decompensated cirrhosis. Methods: We analyzed data for 233 G3 cirrhotic patients. Of these, 70 (30%), 87(37%) and 76 (33%) received SOF/DCV, SOF/DCV/RBV flat dose, and SOF/DCV/RBV weight-based dose, respectively. Treatment duration was 24 weeks. Sustained virological response (SVR) was evaluated at week 12 posttreatment (SVR12). Results: Overall, SVR12 was achieved in 220 out of 233 patients (94.4%). The SVR12 rate was lower in the DCV/SOF group than in the DCV/SOF/RBV flat-dose group and the DCV/SOF/RBV weight-based group (87.1% vs 97.7% and 97.4%, respectively, p=0.007). A higher incidence of anemia occurred in the DCV/SOF/RBV weight-based group compared to those in the other two groups (p

BackgroundCardiovascular disease (CVD) is a major cause of morbidity and mortality after liver transplantation, mostly in patients transplanted for nonalcoholic steatohepatitis, obesity and diabetes. Few data exist on cardiovascular diseases among patients transplanted for viral hepatitis.ObjectiveOur aim is to clarify the cardiovascular risk and subclinical vascular damage among liver transplant recipients for chronic viral hepatitis (i.e. hepatits C virus, hepatis B virus and hepatitis D virus infection).MethodsAdult patients (age ≥ 18 years) with orthotopic liver transplants (OLT) due to viral hepatitis who signed informed consent, and were admitted for a routine follow-up between June 2019 and September 2020 at the Infectious Disease outpatient clinic of the University of Campania Luigi Vanvitelli, Naples, Italy, were prospectively enrolled. An estimation of cardiovascular risk was assessed using three main risk charts, echocolor-Doppler of epiaortic vessels was performed to assess subclinical Intima-Media changes.ResultsA total of 161 patients were evaluated; of these 15 were excluded because not affected by viral hepatitis. 146 patients were considered. 83 patients (56.8%) were considered at high cardiovascular risk according to Framingham, 54 patients (36.9%) to American Heart Association Arteriosclerotic Cardiovascular Disease (ASCVD) score and 19 (13.0%) to Heart Score. Only 8 patients (5.4%) showed a normal carotid ultrasound, while 52 patients (35.6%) had a carotid artery Intima-Media Thickness (IMT) and 86 (58.9%) an atherosclerotic plaque.ConclusionsLiver transplant recipients for virus-related associated liver disease are, in light of the high percentage of carotid lesions, at high risk of CVD. Risk charts compared to subclinical carotid lesions which represent damage already established and a real localization of the disease, seem to underestimate the cardiovascular risk. A chronic inflammatory status, could play a key role. It's important to raise the awareness of cardiovascular risk in liver transplant patients to prevent cardiovascular diseases and improve the timing of early diagnosis of premature vascular lesions.

BackgroundThe aim of the study was to compare coronavirus disease 2019 (COVID-19) severity presentation between oncologic and non-oncologic patients and to evaluate the impact of cancer type and stage on COVID-19 course.MethodsWe performed a multicentre, retrospective study involving 13 COVID-19 Units in Campania region from February to May 2020. We defined as severe COVID-19 presentation the cases that required mechanical ventilation and/or admission to Intensive Care Units (ICU) and/or in case of death.ResultsWe enrolled 371 COVID-19 patients, of whom 34 (9.2%) had a history or a diagnosis of cancer (24 solid, 6 onco-hematological). Oncologic patients were older (p

HCV (Hepatitis C Virus) decreases Health-Related Quality of Life with detriments to physical, mental and social health domains. Interferon and Ribavirin treatment is associated with depression and anxiety that further impairs HRQoL (Health- Related Quality of Life). IFN-free (interferon-free) regimes (Direct Acting Antivirals, DAAs) are safe and highly effective drugs, with improvement also of HRQoL and related Psychological Well-Being. Our aim is to describe how the latest generation IFN-free treatment can change quality of life and related Psychological Well-Being in Italian Chronic Hepatitis C/Cirrhosis affected patients. SF-36v2 (Short Form Health Survey is a 36-item, patient-reported survey of patient health) – HQLQv2 (Hepatitis Quality of Life Questionnaire) was administered at two time points: baseline (n=72) and 12 weeks after the end of therapy [n=72, SVR=72 - Sustained Virologic Response (SVR)]. Patients with chronic HCV undergoing DAAs treatment from two Italian centers were enrolled. The overall average of the answers is configured for most of the domains that make up the questionnaire, with scores above 50. The quality of life of this sample is very close to the average of the US population, with a minimum average score of 45.9 for the Role Emotional scale and an average maximum score of 56.4 for the Vitality scale. Both are significant results from statistical analysis. It seems that DAAs treatment therapy does not affect but improves the general quality and psychological state of adult patients with Chronic HCV infection.

BACKGROUND Coronavirus disease 2019 (COVID‐19) is the cause of a pandemic disease, with severe acute respiratory syndrome by binding target epithelial lung cells through angiotensin‐converting enzyme 2 in humans. Thus, patients with hypertension with COVID‐19 could have worse prognosis. Indeed, angiotensin‐converting enzyme inhibitors and/or angiotensin receptor blockers may interfere with angiotensin‐converting enzyme 2 expression/activity. Thus, patients with hypertension undergoing angiotensin‐converting enzyme inhibitor and/or angiotensin receptor blockers drug therapy may be at a higher risk of contracting a serious COVID‐19 infection and should be monitored. Moreover, in the present study we investigated the effects of angiotensin‐converting enzyme inhibitor versus angiotensin receptor blockers versus calcium channel blockers on clinical outcomes as mechanical ventilation, intensive care unit admissions, heart injury, and death in 62 patients with hypertension hospitalized for COVID‐19 infection. METHODS AND RESULTS The multicenter study was prospectively conducted at Department of Infectious Diseases of Sant'Anna Hospital of Caserta, and of University of Campania "Luigi Vanvitelli" of Naples, at Department of Advanced Surgical and Medical Sciences of University of Campania "Luigi Vanvitelli," Naples, and at General Medical Assistance Unit "FIMG," Naples, Italy. Lowest values of left ventricle ejection fraction predicted deaths (1.142, 1.008–1.294, P

The COVID-19 pandemic led to the hospitalization of an unselected population with the possibility to evaluate the epidemiology of viral hepatitis. Thus, a retrospective multicenter study was conducted in an area of Southern Italy with the aim of assessing the prevalence of HCV and HBV markers and the ability of current screening program to capture cases. We evaluated 2126 hospitalized patients in seven COVID Centers of Naples and Caserta area in which 70% of the Campania population lives. HBsAg and HCV-Ab prevalence was 1.6% and 5.1%, respectively, with no differences between gender. Decade distribution for birth year shows a bimodal trend of HCV prevalence, with a peak (11.6%) in the decade 1930–1939 and a second peak (5.6%) for those born in 1960–1969. An analysis of the screening period imposed by the Italian government for those born between 1969 and 1989 shows that only 17% of cases of HCV infection could be captured. A small alignment of the screening period, i.e., those born from 1960 to 1984, would capture 40% of cases. The data confirm the high endemicity of our geographical area for hepatitis virus infections and underline the need for a tailored screening program according to the regional epidemiology.

Context: The Global Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic has resulted in explosive patterns of transmission in most countries. Nasopharyngeal swabs were the specimen’s collection tools recommended for the diagnosis of SARS-CoV-2 infection, and for monitoring infection outbreaks in communities. Our objective was to report the quality and efficacy of unsupervised self-collected mid turbinate “dry FLOQSwabs” (MT FLOQSwabs) (56380CS01, Copan). There were 111 specimens collected for the study: 36 by health care personnel, from themselves, to verify the quality and efficacy of mid-turbinate swabs; 75 to compare and assess the diagnostic performance, among health care personnel, of nasopharyngeal swabs and self-collected mid-turbinate FLOQSwabs. A collection of 51 specimens was enrolled to define the efficacy of the Testami program (validation). Our analyses demonstrate that self-collected mid-turbinate dry swabs ensure an accuracy of 97.3%, as compared to the standard nasopharyngeal swabs collected by health care workers. Furthermore, the mid-turbinate FLOQSwabs can be stored without medium for six days at room temperature without affecting the molecular diagnosis of the SARS-CoV-2 virus infection. Self-collection of diagnostic specimens at home could offer an avenue to increase testing availability for SARS-CoV-2 infection without asking people to travel to a clinic or a laboratory, thus reducing people’s exposure to infection. Our findings demonstrate that unsupervised self-collection swabs, transported dry, are sensitive, practical and easy-to-use tools and should be considered for diagnosis of SARS-COV-2 and coronavirus disease 2019 (COVID-19) surveillance.

To describe epidemiological and clinical features of patients confirmed as having SARS-CoV-2 infection and managed in isolation at home. We performed a multicenter retrospective study enrolling all SARS-CoV-2-positive adults evaluated from 28 February to 31 May 2020 at one of nine COVID-19 Units in southern Italy: we included patients receiving care at home and those admitted to hospital. We defined patients with not-severe disease if they were asymptomatic or experienced a mild infection that did not need oxygen (O2) therapy and those with a severe infection if hospitalized and required O2 therapy. We enrolled 415 patients with SARS-CoV-2 infection: 77 were managed in isolation at home, 338 required hospital management. The 77 patients in home isolation were less frequently male than hospitalized patients (55% vs. 64%; p < 0.01), had a lower Charlson comorbidity index (median 0 (IQR2) vs. 6 (IQR 3); p < 0.01), and included fewer subjects with an underlying chronic disease (36% vs. 59%; p < 0.01). According to a binomial logistic regression analysis, a younger age (OR: 0.96 (95% IC: 0.94–0.98), p < 0.01) and a low Charlson comorbidity index (OR: 0.66 (95% IC: 0.54–0.83); p < 0.01) were independent factors associated with at-home management. The identification of subjects with SARS-CoV-2 infection who could be managed in home isolation is useful in clinical practice. A younger age and no comorbidities were identified as factors independently associated with home management.

Background: We aimed to evaluate the factors associated with a virological response in a cohort of Hepatitis C virus (HCV)-infected people who inject drugs (PWID) treated with direct acting antivirals (DAAs). Methods: We conducted a multicenter retrospective cohort study enrolling HCV-infected PWID treated with DAAs. The primary outcome evaluated was the sustained virological response (SVR12) rate. Results: Five hundred and twenty HCV-infected PWID treated with all-oral DAA-based regimens were enrolled; a total of 168 (32.3%) patients presented genotype 1a, 109 (21.0%) genotype 1b, and 174 (33.5%) genotype 3; a total 152 of the 520 subjects (29.2%) were cirrhotics; a total 118 (22.7%) and 373 (71.7%) were treated with DAA regimens of second and third generation, respectively; a total 169 (33.6%) patients were receiving an opioid agonist at the start of antiviral therapy. Only 11 subjects (2.1%) did not show an SVR12. A significant correlation was found between treatment with opioid substitution therapy (p < 0.001), Human Immunodeficiency Virus (HIV) coinfection (p = 0.002), and treatment with first- or second-generation regimens (p = 0.0015) and HCV failure. Upon multivariate analysis, treatment with a first- or second-generation DAA was the only factor independently associated with failure (OR 10.4, 95% CI: 1.43 to 76.1, p = 0.02). Conclusions: Treatment with DAAs led to a high SVR12 rate (97.9%) in a large cohort of HCV-infected PWID. The only predictor of viral failure found in our analysis was treatment with first- and second-generation DAA.

AimsTo evaluate the correlation between the hepatic expression pattern of hsa-miR-125a-5p and HBV-DNA and the progression of fibrosis in patients with overt or occult HBV infection.MethodsWe enrolled all the HBsAg-positive treatment naive patients (overt HBV group) and all the HBsAg-negative patients with hepatocellular carcinoma and with a positive HBV-DNA in their hepatic tissue (occult HBV group), who underwent a diagnostic liver biopsy between April 2007 and April 2015. Tissue concentrations of HBV-DNA and hsa-miR-125a-5p were then analyzed by real-time quantitative PCR. Necroinflammatory activity and fibrosis were evaluated according to the Ishak score.ResultsDuring the study period, we enrolled 64 patients with overt and 10 patients with occult HBV infection. In the overt HBV group, 35 of 64 (54.7%) showed a mild fibrosis (staging 0–2), 17 (26.6%) a moderate fibrosis (staging 3–4), while the remaining 12 (18.7%) had a cirrhosis. All patients in the occult HBV group were cirrhotic. Patients with more advanced fibrosis stage showed a higher mean age when compared with those with mild (p

Background and rationale of the study. Effect of Long-term nucleoside/nucleotide (NUC) on hepatocellular carcinoma (HCC) incidence in a population of HBeAg-negative genotype D patients has not been adequately studied in real-life cohorts. Our aim was to evaluate the impact of liver fibrosis and other variables on HCC incidence in this population of patients. Of 745 patients with chronic hepatitis B (CHB), 306 HBeAg-negative genotype D were selected and included in this study. All patients received treatment with NUC for at least 18 months. Patients with CHB or compensated cirrhosis were included. Patients with HCC diagnosed before or during the first 18 months of NUC therapy were excluded.Results. HCC was diagnosed in 2 CHB patients (1.0%) and 23 cirrhosis patients (20%) (OR = 24.41, 95% CI 5.40 < OR < 153.2; p < 0.0001). Multivariate analysis revealed that HCC risk was independently associated with age ≥ 60 years (OR = 6.45, 95% CI 1.22 to 34.0; p = 0.02) and liver cirrhosis (OR = 12.1, 95% CI 1.39 to 106.2; p = 0.02), but not with virological response (VR), and previous resistance to NUC, or rescue therapy. Multivariate analysis in cirrhosis patients revealed that only age ≥ 60 years was an independent risk factor associated with HCC (p = 0.003). Conclusions. Liver cirrhosis and age > 60 years are the stronger risk factors for HCC in genotype D HBeAnegative patients. Previous resistance to NUC in patients that achieved a VR after rescue therapy was not a predictive factor regarding HCC. VR does not appear to significantly reduce the overall incidence of HCC when a patient has already progressed to liver cirrhosis.

To study in HBsAg chronic carriers the expression of liver hsa-miR-125a-5p and its correlation with liver HBV-DNA values and clinical presentation, 27 consecutive Caucasian, HBsAg/anti-HBe/HBV-DNA-positive patients who were naive to nucleos(t)ide analogues and interferon therapy and had no marker of HCV, HDV or HIV infection and no history of alcohol intake were enrolled. For each patient, liver HBV DNA and liver hsa-miR-125a-5p were quantified by real-time PCR in relation to β-globin DNA or RNU6B, respectively. Liver fibrosis and necroinflammation were graded by applying Ishak's scoring system. Liver hsa-miR-125a-5p was detected in all patients enrolled and a correlation between its concentration and liver HBV DNA was demonstrated (p10(3) IU/ml (p6 (p = 0.02) and those with fibrosis score >2 (p2 (p = 0.02) than in patients with a lower load. By multivariate logistic regression analysis, liver hsa-miR-125a-5p was identified as an independent predictor of disease progression: O.R. = 4.21, C.I. 95% = 1.08-16.43, p6; O.R. = 3.12, C.I. 95% = 1.17-8.27, p2. In conclusion, in HBsAg/anti-HBe-positive patients, the liver hsa-miR-125a-5p level correlated with liver and plasma HBV-DNA values and was associated to a more severe disease progression.
