Genetic determinants in a critical domain of ns5a correlate with hepatocellular carcinoma in cirrhotic patients infected with hcv genotype 1b

HCV is an important cause of hepatocellular carcinoma (HCC). HCV NS5A domain‐1 interacts with cellular proteins inducing pro‐oncogenic pathways. Thus, we explore genetic variations in NS5A domain‐1 and their association with HCC, by analyzing 188 NS5A sequences from HCV genotype‐1b infected DAA‐naïve cirrhotic patients: 34 with HCC and 154 without HCC. Specific NS5A mutations significantly correlate with HCC: S3T (8.8% vs. 1.3%, p = 0.01), T122M (8.8% vs. 0.0%, p < 0.001), M133I (20.6% vs. 3.9%, p < 0.001), and Q181E (11.8% vs. 0.6%, p < 0.001). By multivariable analysis, the presence of >1 of them independently correlates with HCC (OR (95%CI): 21.8 (5.7–82.3); p < 0.001). Focusing on HCC‐group, the presence of these mutations correlates with higher viremia (median (IQR): 5.7 (5.4–6.2) log IU/mL vs. 5.3 (4.4–5.6) log IU/mL, p = 0.02) and lower ALT (35 (30–71) vs. 83 (48–108) U/L, p = 0.004), suggesting a role in enhancing viral fitness without affecting necroinflammation. Notably, these mutations reside in NS5A regions known to interact with cellular proteins crucial for cell‐cycle regulation (p53, p85‐PIK3, and β‐ catenin), and introduce additional phosphorylation sites, a phenomenon known to ameliorate NS5A interaction with cellular proteins. Overall, these results provide a focus for further investigations on molecular bases of HCV‐mediated oncogenesis. The role of these NS5A domain‐1 mutations in triggering pro‐oncogenic stimuli that can persist also despite achievement of sustained virological response deserves further investigation

Cancer testis antigen expression in primary and recurrent vulvar cancer: Association with prognostic factors

Cancer testis tumour associated antigens (C/T-TAAs) were investigated in several gynaecologic and non-gynaecologic neoplasms as possible prognostic markers and targets for immunotherapy The objective of the present study was to evaluate C/T-TAA expression patterns and prognostic significance in patients affected by vulvar cancer. Melanoma antigen E (MAGE)-A1, MAGE-A4 and NY-ESO-1 expression was determined by immunohistochemistry in paraffin -embedded tissue specimens from 45 primary and 14 recurrent vulvar carcinomas treated with surgery. MAGE-A1, MAGE-A4 and NY-ESO-1 were expressed in 25 (42%), 38 (64%) and 40 (68%) of the 59 samples, respectively MAGE-A4 was significantly more frequently expressed in tumours with lymph node metastases (p < 0.002) and in recurrent tumours (p < 0.02). NY-ESO-1 was more highly expressed by moderately or poorly differentiated tumours (p < 0.01). This study demonstrates that vulvar cancer frequently expresses C/T-TAAs. Antigen expression correlates with the presence of lymph node metastases and poor tumour differentiation. (c) 2007 Elsevier Ltd. All rights reserved

MAGE-A and NY-ESO-1 expression in cervical cancer: investigation on prognostic factors and effect of chemotherapy

HepaDisk \u2013 A new quality of life questionnaire for HCV patients

Background: Since most patients with hepatitis C virus (HCV) infection now receive treatment irrespective of liver disease severity, special attention to patient quality of life (QoL), including psycho-social aspects, is required. No QoL questionnaire is specific for patients with HCV. Aims: To develop and validate a short Italian questionnaire (HepaDisk) assessing the QoL of patients affected by HCV with intuitive graphic results that is understandable by patients and physicians. Methods: A questionnaire, drafted by a steering committee, underwent a Delphi survey. A multicenter, observational study was conducted to validate the developed HepaDisk versus other tools (CLDQ-I, SF-36, WPAI:HCV), and to evaluate its correlation with disease severity in Italian patients with HCV. Results: The 10-item questionnaire was validated in 214 patients. HepaDisk showed a high correlation with CLDQ overall score and WPAI:HCV activity impairment (Spearman's rank correlation: 0.651 and 0.595, respectively) and a lower correlation with SF-36. Strong internal consistency (Cronbach coefficient: 0.912), good test–retest reliability (Pearson's correlation coefficient: 0.789; 95% CI, 0.714–0.865), and responsiveness to changes among improved patients were demonstrated. Conclusion: HepaDisk is a reliable and user-friendly tool that can monitor disease impact on patient QoL over time, providing a visual representation easily understandable by both patients and physicians

SAFE trial: an ongoing randomized clinical study to assess the role of cardiotoxicity prevention in breast cancer patients treated with anthracyclines with or without trastuzumab

Over the years, thanks to the addition of new generation systemic agents, as well as the use of more advanced and precise radiotherapy techniques, it was able to obtain a high curability rate for breast cancer. Anthracyclines play a key role in the treatment of breast disease, with a well-known benefit on disease-free survival of patients with positive nodal status. Trastuzumab have shown a significant outcome advantage after 1-year administration in case of HER2-positive disease. Unfortunately, significant increase in cardiotoxicity has been observed after anthracyclines and trastuzumab therapies. Even though the cardiology and oncology community strongly recommend a cardiotoxicity prevention strategy for this subset of patients, there is still no consensus on the optimal patient\ue2\u80\u99s approach. We aimed to review the published and ongoing researches on cardioprevention strategies and to present the SAFE trial (CT registry ID: NCT2236806; EudraCT number: 2015-000914-23). It is a randomized phase 3, four-arm, single-blind, placebo-controlled study that aims to evaluate the effect of bisoprolol, ramipril or both drugs, compared to placebo, on subclinical heart damage evaluated by speckle tracking cardiac ultrasound in non-metastatic breast cancer patients

A “One-Health” approach for diagnosis and molecular characterization of SARS-CoV-2 in Italy

The current pandemic is caused by a novel coronavirus (CoV) called SARS-CoV-2 (species Severe acute respiratory syndrome-related coronavirus, subgenus Sarbecovirus, genus Betacoronavirus, family Coronaviridae). In Italy, up to the 2nd of April 2020, overall 139,422 confirmed cases and 17,669 deaths have been notified, while 26,491 people have recovered. Besides the overloading of hospitals, another issue to face was the capacity to perform thousands of tests per day. In this perspective, to support the National Health Care System and to minimize the impact of this rapidly spreading virus, the Italian Ministry of Health involved the Istituti Zooprofilattici Sperimentali (IZSs), Veterinary Public Health Institutes, in the diagnosis of SARS-CoV-2 by testing human samples. The Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise is currently testing more than 600 samples per day and performing whole genome sequencing from positive samples. Sequence analysis of these samples suggested that different viral variants may be circulating in Italy, and so in Abruzzo region. CoVs, and related diseases, are well known to veterinarians since decades. The experience that veterinarians operating within the Public Health system gained in the control and characterization of previous health issues of livestock and poultry including avian flu, bluetongue, foot and mouth disease, responsible for huge economic losses, is certainly of great help to minimize the impact of this global crisis

High Efficacy and Safety of Flat-Dose Ribavirin Plus Sofosbuvir/Daclatasvir in Genotype 3 Cirrhotic Patients

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<0.007). Conclusions: We found that the DCV/SOF/RBV flat-dose regimen is an effective treatment in terms of efficacy and safety in patients with G3-HCV compensated or decompensated cirrhosis. Therefore, antiviral regimens without RBV should be restricted only to naïve patients with G3-HCV compensated cirrhosis who have a clear contraindication for RBV
