Progression From Paroxysmal to Persistent Atrial Fibrillation. Clinical Correlates and Prognosis

Objectives: We investigated clinical correlates of atrial fibrillation (AF) progression and evaluated the prognosis of patients demonstrating AF progression in a large population. Background: Progression of paroxysmal AF to more sustained forms is frequently seen. However, not all patients will progress to persistent AF. Methods: We included 1,219 patients with paroxysmal AF who participated in the Euro Heart Survey on AF and had a known rhythm status at follow-up. Patients who experienced AF progression after 1 year of follow-up were identified. Results: Progression of AF occurred in 178 (15%) patients. Multivariate analysis showed that heart failure, age, previous transient ischemic attack or stroke, chronic obstructive pulmonary disease, and hypertension were the only independent predictors of AF progression. Using the regression coefficient as a benchmark, we calculated the HATCH score. Nearly 50% of the patients with a HATCH score >5 progressed to persistent AF compared with only 6% of the patients with a HATCH score of 0. During follow-up, patients with AF progression were more often admitted to the hospital and had more major adverse cardiovascular events. Conclusions: A substantial number of patients progress to sustained AF within 1 year. The clinical outcome of these patients regarding hospital admissions and major adverse cardiovascular events was worse compared with patients demonstrating no AF progression. Factors known to cause atrial structural remodeling (age and underlying heart disease) were independent predictors of AF progression. The HATCH score may help to identify patients who are likely to progress to sustained forms of AF in the near future. \ua9 2010 American College of Cardiology Foundation

Chlamydia trachomatis infection and HPV/Chlamydia trachomatis co-infection among HPV-vaccinated young women at the beginning of their sexual activity

Purpose: This study investigated the prevalence of Chlamydia trachomatis infection, co-infection with Human Papillomavirus (HPV) and associated risk factors in a cohort of sexually active young women enrolled in an ongoing trial on HPV vaccination at the European Institute of Oncology (IEO, Milan, Italy). Methods: Cervical samples were collected from 591 girls (median age 18.8 years) at the beginning of their sexual activity. At the time of sample collection, 354 women had not yet been vaccinated, and 237 women had been vaccinated for at least 12 months. All samples were analyzed through a molecular assay for the detection of C. trachomatis infection. Demographic, behavioral risk factors and high-risk HPV (HR-HPV) status were investigated. Results: The prevalence of C. trachomatis infection was 4.9 % and HPV/C. trachomatis co-infection rate was 1.5 %. The exact analysis has not underlined statistical significance for the variables considered, except for the infection with HR-HPV (p < 0.001). The prevalence of C. trachomatis infection among women who had not been immunized and those already vaccinated was similar (5.6 vs 3.8 %). However, the rate of HPV/C. trachomatis co-infection was twice as high in unvaccinated women (2 %) compared to vaccinated women (0.8 %). Conclusions: Over 16 % of young women had at least one of the two STIs investigated. The risk of C. trachomatis infection was higher in HR-HPV infected compared to HR-HPV uninfected young women. The rate of co-infection was halved in HPV-vaccinated compared to unvaccinated women. This study underlines that HPV vaccination can confer benefits also in terms of co-infections prevention, leading to a decreased risk of developing cervical malignancies

Invasive meningococcal disease in Italy: from analysis of national data to an evidence-based vaccination strategy

none14noIntroduction: Invasive meningococcal disease (IMD) is one of the most severe vaccine-preventable disease not yet under control. In Italy, although different anti-meningococcal vaccines are available, their offer among regions is heterogeneous. The aim of this study is to describe the epidemiology of IMD in Italy based on analysis of national surveillance data for 2011-2017 to optimize the vaccination strategy.Methods: IMD surveillance data from the Italian National Health Institute were analysed. Microsoft Excel was used to present trend analysis, stratifying by age and serogroups.Results: In Italy, during the period 2011-2017, the incidence of IMD increased from 0.25 cases/100,000 inhabitants in 2011 to 0.33 cases/100,000 in 2017. Most cases after 2012 were caused by non-B serogroups. The number of cases in subjects aged 25-64 years increased steadily after 2012 (36 cases in 2011, 79 in 2017), mostly due to non-B serogroups, representing more than 65% of cases in those aged 25+ years.Conclusions: In the period from 2011 to 2017, the incidence of IMDs increased in Italy. The increase, probably due also to a better surveillance, highlights the importance of the disease in the adult population and the high level of circulation of non-B serogroups in particular after 2012. Our analysis supports an anti-meningococcal vaccination plan in Italy that should include the highest number of preventable serogroups and be aimed at vaccinating a wider population through a multicohort strategy.openIgidbashian, S; Bertizzolo, L; Tognetto, A; Azzari, C; Bonanni, P; Castiglia, P; Conversano, M; Esposito, S; Gabutti, G; Icardi, G; Lopalco, P L; Vitale, F; Parisi, S; Checcucci Lisi, GIgidbashian, S; Bertizzolo, L; Tognetto, A; Azzari, C; Bonanni, P; Castiglia, P; Conversano, M; Esposito, S; Gabutti, G; Icardi, G; Lopalco, P L; Vitale, F; Parisi, S; Checcucci Lisi,

Randomized study of traditional versus aggressive systolic blood pressure control (Cardio-Sis): rationale, design and characteristics of the study population. Cardio-Sis Study Group

The hypothesis that a therapeutic strategy aimed at lowering systolic blood pressure (SBP) below 130 mm Hg is superior to a conventional strategy targeted at below 140 mm Hg in hypertensive subjects has never been tested in randomized intervention studies. The Studio Italiano Sugli Effetti Cardiovascolari del Controllo della Pressione Arteriosa Sistolica (Cardio-Sis) is a multi-centre study in non-diabetic, treated hypertensive subjects aged >55 years with uncontrolled SBP (>or=150 mm Hg) and at least one additional cardiovascular risk factor (ClinicalTrials.gov identifier: NCT00421863). Subjects are randomized to an SBP goal <140 mm Hg (conventional) or <130 mm Hg (aggressive), independently of baseline and achieved diastolic blood pressure (BP). Anti-hypertensive drugs dispensed for the study are restricted to a list of specific drugs. The primary outcome of the study is based on regression of left ventricular hypertrophy (LVH) using electrocardiography (ECG). The hypothesis is that subjects without LVH regression or with new development of LVH 2 years after randomization are 19% with conventional strategy and 12% with aggressive strategy. Secondary outcome is a composite pool of pre-specified fatal and non-fatal events. Randomization of 1111 subjects was completed by February 2007. Mean age of subjects (41% men) at entry was 67 years. BP was 158/87 mm Hg (systolic/diastolic) and prevalence of LVH by ECG was 21.0%. Cardio-Sis is the first randomized study specifically designed to compare two different SBP goals. Results will be broadly applicable to subjects with uncontrolled SBP under anti-hypertensive treatment
