Has VZV epidemiology changed in Italy? Results of a seroprevalence study
2017
The aim of the study was to evaluate if and how varicella prevalence has changed in Italy. In particular a seroprevalence study was performed, comparing it to similar surveys conducted in pre-immunization era. During 2013–2014, sera obtained from blood samples taken for diagnostic purposes or routine investigations were collected in collaboration with at least one laboratory/center for each region, following the approval of the Ethics Committee. Data were stratified by sex and age. All samples were processed in a national reference laboratory by an immunoassay with high sensitivity and specificity. Statutory notifications, national hospital discharge database and mortality data related to V…
Mandatory vaccinations in European countries, undocumented information, false news and the impact on vaccination uptake: the position of the Italian …
2018
Abstract Background High rates of vaccination coverage are important in preventing infectious diseases. Enforcing mandatory vaccinations is one of the strategies that some Countries adopted to protect the community when vaccination coverage is not satisfactory. In Italy, in 2017 vaccination against diphtheria, tetanus, pertussis, hepatitis B, poliovirus, Haemophilus influenzae type b, measles, mumps, rubella and varicella became compulsory in childhood. In order to contrast vaccination policies, anti-vaccination campaigns contribute to the spread of fake news. Among them, there is the false information that Italy is the only one country with mandatory vaccination policy. Aim of our study is…
Space-time airborne disease mapping applied to detect specific behaviour of varicella in Valencia, Spain.
2015
Airborne diseases are one of humanity's most feared sicknesses and have regularly caused concern among specialists. Varicella is an airborne disease which usually affects children before the age of 10. Because of its nature, varicella gives rise to interesting spatial, temporal and spatio-temporal patterns. This paper studies spatio-temporal exploratory analysis tools to detect specific behaviour of varicella in the city of Valencia, Spain, from 2008 to 2013. These methods have shown a significant association between the spatial and the temporal component, confirmed by the space-time models applied to the data. High relative risk of varicella is observed in economically disadvantaged region…
Recovery of Varicella-Zoster Virus–Specific T Cell Immunity after T Cell–Depleted Allogeneic Transplantation Requires Symptomatic Virus Reactivation
2008
Abstract Reactivated varicella-zoster virus (VZV) infection causes herpes zoster and commonly occurs after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Because VZV-specific T cell immunity is essential to prevent virus reactivation, we developed an interferon-γ enzyme-linked immunosorbent spot (ELISPOT) assay for the sensitive detection of VZV-reactive T cells at the single-cell level ex vivo. We used this assay to monitor the frequency of VZV-reactive T cells in 17 seropositive patients during the first year after T cell–depleted allo-HSCT. The patients did not receive anti-herpesvirus prophylaxis after stem cell engraftment. Independent of the magnitude of transferred d…
Cellular immune response of a varicella vaccine following simultaneous DTaP and VZV vaccination.
1999
Abstract Background : Chickenpox and zoster are an important cause of morbidity among children and adults. The ability of a new, thermostable vaccine to induce varicella–zoster-virus (VZV)-specific humoral and cell mediated immunity when given simultaneously with diphtheria–tetanus-acellular pertussis vaccine (DTaP) as a booster dose in the second year of life was investigated. Methods : A new, temperature stable varicella vaccine (OKA-strain, SB-Biologicals, Rixensart, Belgium) was given simultaneously with a booster dose of DTaP vaccine. VZV-specific humoral and cell-mediated immunity was studied in the first 27 out of 232 vaccinated children at 16–28 months of age, from blood samples dra…
Impact of universal vaccination against varicella in Italy.
2014
In Italy, the introduction of Universal Varicella Vaccination (UVV) has been decided but postponed, as a national programme, until 2015, when data from Regions which have already implemented it will be available. Starting from 2003, eight Italian Regions (Basilicata, Calabria, Friuli Venezia Giulia, Apulia, Sardinia, Sicily, Tuscany and Veneto) have progressively introduced UVV, in their immunization programme, with different schedules in children aged 13–15 months and 5–6 years, currently a two-dose schedule is adopted by all Regions. In June 2013, an Interregional Group on Varicella Vaccination (IGVV) has been established in order to assess the effectiveness of varicella vaccination with …
Can SARS‐CoV‐2 vaccine increase the risk of reactivation of Varicella zoster? A systematic review
2021
Abstract Introduction Although the COVID‐19 vaccination is deemed safe, exact incidence and nature if adverse effects, particularly dermatological ones, are still unknown. Objective To describe the demographic, clinical, morphological characteristics, outcomes, and timing of development of herpes zoster to the various COVID‐19 vaccines. And to identify on whether COVID‐19 vaccine has temporal relationship between development of herpes zoster (HZ). Methods We have performed a systemic review of articles from PubMed and Embase using MeSH and keywords like “Shingles,” “Herpes zoster,” “Varicella zoster,” “COVID‐19,” “Vaccine,” “SARS‐CoV‐2.” No filters including country of publication, language…
A simplified clinical risk score predicts the need for early endoscopy in non-variceal upper gastrointestinal bleeding
2014
Abstract Background Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. Aims To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. Methods In this prospective, multicentre study patients with bleeding who underwent upper endoscopy were enrolled. The accuracy for high risk endoscopic stigmata of the T-score was compared with that of the Glasgow Blatchford risk score. Results Overall, 602 patients underwent early upper endoscopy, and…
Case report: Trans-papillary free stenting of the cystic duct and of the common bile duct in a double biliary ducts anastomoses of a right lobe livin…
2021
Abstract Background One of the major issues related to the living donor liver transplantation recipient outcome is still the high rate of biliary complication, especially when multiple biliary ducts are present and multiple anastomoses have to be performed. Case presentation and conclusion We report a case of adult-to-adult right lobe living donor liver transplantation performed for a recipient affected by alcohol-related cirrhosis with MELD score of 17. End-stage liver disease was complicated by refractory ascites, portal hypertension, small esophageal varices and portal gastropathy, hypersplenism, and abundant right pleural effusion. Here in the attached video we described the adult-to-ad…
Enteroscopic Cyanoacrylate Sclerotherapy of Jejunal and Gallbladder Varices in a Patient with Portal Hypertension
2001
Bleeding from varices outside the gastroesophageal region is a rare, but regularly reported complication of portal hypertension. The treatment differs from the management of esophageal and gastric varices. We present here a report on the diagnosis and treatment of bleeding jejunal and gallbladder varices in a man with portal hypertension caused by chronic calcifying pancreatitis. The patient was suffering from recurrent, frequent, and massive gastrointestinal bleeding from varices at the anastomotic area of a cholecystojejunostomy. For diagnostic purposes, we carried out percutaneous Duplex ultrasonography and push enteroscopy with the Doppler technique. The treatment of varices in this are…
