Web-Based HIV Testing in Abruzzo, Italy: Analysis of 15-Month Activity Results.

Undiagnosed cases of HIV infection in developed countries are estimated at 20-30% of individuals living with HIV. Web-based strategies may represent a new approach to easier, wider, and unrestricted access to early testing. The Abruzzo Region, Italy, developed a Web-based tool to recruit persons at high risk of HIV and other sexually transmitted infections (STIs). At the Website www.failtestanchetu.it , browsers found information on STIs (HIV, hepatitis B and C, and syphilis), a structured questionnaire called "risk calculator" to assess one's own risk behaviors and direct booking of their test at one of six sites throughout the region. The Website was advertised on local media and in pharmacies, high schools, sports facilities, and factories. Between February 1, 2014, and May 31, 2015, about 6000 users visited the Website; 3046 people attended a visit for counseling on risk behaviors, signs, or symptoms of STIs and accepted blood drawing for HIV, hepatitis B Virus (HBV), hepatitis C Virus (HCV), and syphilis tests. Fifty-eight (1.90%) subjects were positive for HCV, 56 (1.84%) for HBsAg, 90 (2.95%) for Treponema pallidum antibodies, and 28 (0.92%) for HIV. Ninety-two percent of HIV-positive patients were successfully linked to care. Late presenters were less frequent in this sample than in the population diagnosed with HIV in Italy in 2014. An overall 7% proportion of HIV, HBV, HCV, and syphilis-unaware cases were all transferred to care, with the exception of three people. HIV seropositivity among testers was higher than 2/1000, the cost-effectiveness threshold suggested for effective testing. Therefore, our Web-based unrestricted and free access methodology appears worth further and wider evaluation.

High seroprevalence of HCV in the Abruzzo Region, Italy: results on a large sample from opt-out pre-surgical screening.

PURPOSE: Available estimates of the prevalence of chronic HCV infection in Italy are quite conflicting, varying from 1.5 to 22.5%, with an apparent north to south gradient. As Direct Acting Antivirals are expensive, both National and local governmental Agencies are in urgent need of detailed and reliable estimates of HCV patients to be treated, nationwide and in each district. We investigated the prevalence of anti-HCV antibodies in a large unselected sample of surgical patients providing consent to in-hospital opt-out pre-surgical HCV screening, at two hospitals from the Abruzzo Region, Italy. METHODS: Data were retrieved for 55,533 screened patients (4.1% of the total population in the Abruzzo Region), admitted in the Orthopedic and General Surgery wards of Pescara and Teramo Hospitals from 1999 to 2014. RESULTS: The prevalence of anti-HCV antibodies was 4.4% in the total sample. HCV-positive patients had a mean age of 63.8 ± 19.9 years; 49.2% were males. From 1999 to 2014, the prevalence of HCV antibodies decreased from 5.4% to 4.1%; at both sites, however, two age-related-peaks were evidenced, the first among patients aged 30-49 years, the second among those older than 70 years. Statistical analyses confirmed a significant trend to decrease over time and a higher prevalence in Pescara and among males (all p < 0.01). CONCLUSIONS: Data retrieved from opt-out pre-surgical screening programs may allow inexpensive and easy-to-perform estimates of HCV seroprevalence from large samples of unselected patients with a well-defined provenience, which may turn useful for future treatment resource allocation.

May some HCV genotype 1 patients still benefit from dual therapy? The role of very early HCV kinetics.

When treating HCV patients with conventional dual therapy in the current context of rapidly evolving HCV therapy, outcome prediction is crucial and HCV kinetics, as early as 48 hours after the start of treatment, may play a major role. We aimed at clarifying the role of HCV very early kinetics. We consecutively enrolled mono-infected HCV patients at 7 treatment sites in Central Italy and evaluated the predictive value of logarithmic decay of HCV RNA 48 hours after the start of dual therapy (Delta48). Among the 171 enrolled patients, 144 were evaluable for early and sustained virological response (EVR, SVR) prediction; 108 (75.0%) reached EVR and 84 (58.3%) reached SVR. Mean Delta 48 was 1.68 ± 1.22 log10 IU/ml, being higher in patients with SVR and EVR. Those genotype-1 patients experiencing a Delta 48 >2 logs showed a very high chance of success (100% positive predictive value), even in the absence of rapid virological response (RVR). Evaluation of very early HCV kinetics helped identify a small but significant proportion of genotype-1 patients (close to 10%) in addition to those identified with RVR, who could be treated with dual therapy in spite of not reaching RVR. In the current European context, whereby sustainability of HCV therapy is a crucial issue, conventional dual therapy may still play a reasonable role in patients with good tolerance and early prediction of success.

Whole-Genome Sequence of Listeria monocytogenes Serovar 4b Strain IZSAM_Lm_hs2008, Isolated from a Human Infection in Italy.

Listeria monocytogenes is one of the most important foodborne pathogens. In this report, we present the complete and annotated genome of L. monocytogenes sequence type 06 (ST06) serovar 4b strain IZSAM_Lm_hs2008, isolated from an adult immunocompetent patient who developed the disease and died.
