combined antiretroviral therapy cart reduces aids related and non aids related mortality a temporal analysis from time of seroconversion sc

Objectives: To estimate changes of AIDS and non-AIDS mortalities from 1996 to 2010 comparing (2004-2010) vs. (1996-2003) periods from the time of HIV-seroconversion (SC). Methods: Data derived from an Italian multicentre prospective and open cohort; competing risks approach was applied estimating the cumulative incidence functions (CIF) for AIDS and non-AIDS deaths over time from SC with delayed entries in the two cART periods. Cox-cause-specific hazards models were applied to estimate relative hazards (RH) of AIDS and non-AIDS related deaths. Results: Of 2,249 individuals with known SC date followed from SC and from January 1996 to December 2010, 1,779 were survived, seroconverted or followed during 1996-2003, while 1,715 during 2004-2010. A total of 278 deaths occurred from 1996 to 2010: 197 in the early years of cART [61 (31%) non-AIDS deaths], and 81 during more recent cART period [48 (59%) non-AIDS deaths]. The CIF of AIDS related deaths was higher than CIF of non-AIDS related deaths in the early period [for instance, estimates at 15 yrs from SC: CIF of AIDS-related death = 0.15 (95% CI: 0.12-0.19 ) and CIF of non-AIDS related = 0.09 (95% CI: 0.07-0.12)], whilst in 2004-2010 period the CIF of non-AIDS related deaths was slightly higher [estimates at 15 yrs from SC: CIF of non-AIDS related = 0.03 (95% CI: 0.02-0.04) vs. CIF of AIDS-related death = 0.02 (95% CI: 0.02-0.04)]. Comparing the two periods by Cox proportional-cause-specific models, the hazard was lower for AIDS deaths than for non-AIDS related deaths [RH of non-AIDS deaths from last viral load (VL) < 200 copies/mL was 0.60 (95% CI (0.35-1.03)], while of AIDS-deaths was 0.32 (95% CI: 0.17-0.62), both RH relative to (2004-2010) vs. (1996- 2003)]. Conclusions: Considering early years of the cART period as a reference, we observed a decrease in both AIDS and non-AIDS-mortalities. In more recent cART years, non-AIDS mortality tended to decline less than AIDS-relatedmortality since HIV-SC, even after effective cART

Demographic and socio-economic determinants of poor HIV-risk perception at first HIV diagnosis: analysis of the HIV Surveillance data, Italy 2010-2016

HIV infections in Italy has not undergone a substantial decline over recent years. For this reason, we analysed risk-factors and socio-economic indicators of HIV-risk perception in HIV surveillance data

Performance of V3-based HIV-1 sero subtyping in HIV endemic areas

HIV-1 serosubtyping based on reactivity to peptides from the V3 region of gp120 is a low-cost and easy to perform procedure often used in geographical areas with high prevalence and incidence of HIV infection. We evaluated the performance of V3-based serotyping on 148 sera from 118 HIV-1-infected individuals living in Uganda, with estimated dates of seroconversion. Of the 148 tested samples, 68 (46.0%) specifically reacted with only one of the V3 peptides included in the test (SP), 64 (43.2%) did not react with any peptide (NR) and 16 (10.8%) reacted with two or more peptides (CR). According to the estimated seroconversion date, the large majority of samples collected early after infection belonged to the NR group. These samples had also a low Avidity Index. In contrast, samples collected later after infection belonged mainly to CR and SP groups and had also a higher avidity index. These results indicate that the performance of V3-based assays depends on maturation of HIV-specific immune response and can be significantly lowered when these tests are carried out on specimens collected from recently infected individuals

Continued high prevalence of HIV, HBV and HCV among injecting and noninjecting drug users in Italy

We estimated the prevalence of HIV, HBV and HCV infections among injecting and non-injecting drug users treated within public drug-treatment centres in Italy to determine the correlates of infection. In the sample of 1330 drug users, the prevalence of HIV was 14.4% among drug injectors and 1.6% among non-injectors; the prevalence of HBV was 70.4% among injecting drug users and 22.8% among non-injectors and of HCV was 83.2% among injecting drug users and 22.0% among non-injectors. Old age, unemployment, and intravenous drug use were significantly correlated with each of the infections, as well as a longer history of injecting drug use. The results indicate that these infections continue to circulate among drug users, highlighting the need for monitoring of this group in Italy

Incidence of Newly HIV Diagnosed Cases among Foreign Migrants in Italy: 2006-2013

Objective: In Europe, during the last years the proportion of foreign migrants among AIDS and HIV cases is growing. In Italy, the number of new cases of HIV represented by foreign migrants has progressively increased, but the new HIV diagnoses incidence among foreign migrants has decreased, because of the increase in the total number of foreign migrants in recent years. Nevertheless, the new HIV diagnoses incidence among foreign migrants is still high if compared to that among Italians. The aim of the study was to analyze the characteristics of foreign migrants with a new HIV diagnosis and the new HIV diagnoses incidence among foreign migrants diagnosed in Italy between 2006 and 2013. Methods: The new diagnoses incidence was calculated as the ratio between the number of new HIV diagnoses among foreign migrants and the number of foreign migrants residing in Italy. The new HIV diagnoses incidence was compared with that among Italians using the standardized incidence ratio (SIR) adjusted by age and gender. Results: During the study period (2006-2013), of the 25,545 new diagnoses reported by the HIV surveillance system, 28.8% were among foreign migrants. The incidence of new HIV diagnoses among foreign migrants for the entire study period was 26.7 cases per 100,000 foreign migrant residents, compared to 5.1 per 100,000 among Italians. The incidence of new HIV diagnoses decreased over time for foreign migrants: from 42.5 per 100,000foreign migrant residents in 2006 to 20.0 per 100,000 foreign migrant residents in 2013, whereas for Italians it remained stable. The SIR confirmed the marked difference between the two populations: specifically the overall incidence of new diagnoses was more than four times higher among foreign migrants, compared to Italians.Conclusion: The results stress the need to reinforce the efforts aimed at reducing the circulation of HIV in this population

Estimated burden of Chlamydia trachomatis female infection and consequent severe pelvic inflammatory disease, Italy, 2005-2016

Chlamydia trachomatis (Ct) is the leading sexually transmitted infection (STI) across Europe. In Italy, prevalence is low in general population; anyway, predominance of asymptomatic infections, passive voluntary reporting, variable diagnostic criteria and coding practices suggest for considerable underestimation, preventing assessment of real burden of disease and health intervention. We analysed data on female genital Ct infection registered in STI sentinel surveillance systems in Italy from 2005 through 2016 and found 3,305 women. Among them, those aged 20-24 years had the highest disability-adjusted life years (DALYs) estimation equal to 106.77 DALYs per 100,000-stratum specific population. Through the study period, incidence rate (IR) for female Ct infection increased significantly from 2.9 to 7.1 per 100,000 resident population. Besides, we analysed data on pelvic inflammatory disease (PID) sequela reported from the National Hospital Information system (NHIS) in the same period. We found 287 women hospitalised with concurrent PID and Ct infection. We recommend targeted screening programmes in women aged 20-24, definition of nationwide active surveillance system, standardisation of diagnostic criteria and ICD-9CM coding practices

The continued ageing of people with AIDS in Italy: recent trend from the national AIDS Registry

Introduction. In industrialized countries, the availability of highly active antiretroviral  therapy (HAART) caused a slow but substantial ageing of the AIDS epidemic mainly  due to the longer survival of persons with HIV/AIDS which has turned HIV into a manageable, chronic disease. The number of older people with AIDS is growing in many  European countries.We described the impact of AIDS among persons aged 50 years or more in Italy and  compared the characteristics of these cases with those of persons diagnosed with AIDS  at an age younger than 50. Methods. The source of data was the Italian AIDS Registry, from 1982 to 2011. We  defined “older” persons those aged 50 years or more, and younger individuals those aged  less  than  50  years.  We  built  two  multivariate  logistic  regression  models:  the  first  one  to identify factors associated with being older, and the second one to identify AIDS-defining diseases correlated with being older. Variables with a P value of < 0.05 were  entered in the model.Results. Of the total AIDS cases, 10.5% were among persons older than 49 years. This  proportion progressively increased from 0.0% in 1983 to 26.4% in 2011. Among older  cases, the incidence of AIDS was 2.0 per 100 000 residents in 1996, then decreased  to 1.4 per 100 000 in 2000 and levelled off around 1 per 100 000 residents until 2011.  Compared to younger cases, older cases were more frequently males, Italians, diagnosed  with AIDS in recent years, residing in Northern or Central Italy, non-injecting drug users, and late testers. Discussion. These findings stress the need for physicians to consider carefully the possibility of HIV infection among older individuals not to miss the opportunity to deliver  prevention messages, offer HIV testing, and make an early diagnosis.  

Hemorheological profiles and chronic inflammation markers in transfusion-dependent and non-transfusion- dependent thalassemia

: The rheological properties of blood play an important role in regulating blood flow in micro and macro circulation. In thalassemia syndromes red blood cells exhibit altered hemodynamic properties that facilitate microcirculatory diseases: increased aggregation and reduced deformability, as well as a marked increase in adherence to the vascular endothelial cells. A personalized approach to treating thalassemia patients (transfusions, iron chelation, and splenectomy), has increased patients' life expectancy, however they generally present many complications and several studies have demonstrated the presence of high incidence of thromboembolic events. In this study the hemorheological profiles of thalassemia patients have been characterized to point out new indices of vascular impairment in thalassemia. Plasma viscosity, blood viscosities at low and high shear rates (η1 and η200, respectively), erythrocyte aggregation index (η1/η200), and the erythrocyte viscoelastic profile (elastic modulus G', and viscous modulus G") have been studied in transfusion-dependent and non-transfusion-dependent thalassemia patients. Moreover, the levels of inflammation biomarkers in thalassemia have been evaluated to investigate a relationship between the biomarkers, the disease severity and the rheological parameters. The biomarkers studied are the main components of the immune and endothelial systems or are related to vascular inflammation: cytokines (IL-2, IL-6, IL-10, IL-17A, TNF-alpha), chemokines (IL-8, MIP-1alpha), adipocytokines (leptin and adiponectin), growth factors (VEGF, angiopoietin-1), adhesion molecules (ICAM-1, VCAM-1, E-selectin, L-selectin), and a monocyte/macrophage activation marker (CD163). This study shows that transfusion-dependent thalassemia patients, both major and intermedia, have blood viscosities comparable to those of healthy subjects. Non-transfusion-dependent thalassemia intermedia patients show high blood viscosities at low shear rates (η1), corresponding to the flow conditions of the microcirculation, an increase in erythrocyte aggregation, and high values of the elastic G' and viscous G" modules that reflect a reduced erythrocyte deformability and an increase in blood viscosity. Levels of cytokines, chemokines and adhesion molecules are different in transfusion- and non-transfusion dependent patients and positive correlations between η1 or η1/η200 and the cytokines IL-6 and IL-10 have been observed. The evaluation of the hemorheological profiles in thalassemia can provide new indicators of vascular impairment and disease severity in thalassemia in order to prevent the onset of thromboembolic events

Post-migration acquisition of HIV: Estimates from four European countries, 2007 to 2016.

BackgroundThe assumption that migrants acquire human immunodeficiency virus (HIV) before migration, particularly those from high prevalence areas, is common.AimWe assessed the place of HIV acquisition of migrants diagnosed in four European countries using surveillance data.MethodsUsing CD4+ T-cell count trajectories modelled to account for seroconversion bias, we estimated infection year of newly HIV-diagnosed migrants residing in the United Kingdom (UK), Belgium, Sweden and Italy with a known arrival year and CD4+ T-cell count at diagnosis. Multivariate analyses identified predictors for post-migration acquisition.ResultsBetween 2007 and 2016, migrants constituted 56% of people newly diagnosed with HIV in the UK, 62% in Belgium, 72% in Sweden and 29% in Italy. Of 23,595 migrants included, 60% were born in Africa and 70% acquired HIV heterosexually. An estimated 9,400 migrants (40%; interquartile range (IQR): 34-59) probably acquired HIV post-migration. This proportion was similar by risk group, sex and region of birth. Time since migration was a strong predictor of post-migration HIV acquisition: 91% (IQR: 87-95) among those arriving 10 or more years prior to diagnosis; 30% (IQR: 21-37) among those 1-5 years prior. Younger age at arrival was a predictor: 15-18 years (81%; IQR: 74-86), 19-25 years (53%; IQR: 45-63), 26-35 years (37%; IQR: 30-46) and 36 years and older (25%; IQR: 21-33).ConclusionsMigrants, regardless of origin, sex and exposure to HIV are at risk of acquiring HIV post-migration to Europe. Alongside accessible HIV testing, prevention activities must target migrant communities
