The aim of this study was to assess the effectiveness of telaprevir-based and boceprevir-based treatments with respect to the HIV status. A prospective multicentre study was conducted among 22 Infectious Disease centres in Italy. Demographic, HIV and HCV related variables were collected, as well as data on HCV viral decay, sustained virologic response (SVR12) and grade 3-4 adverse events. Overall, 162 patients (24.7% HIV/HCV coinfected) received HCV treatment. Out of 145 evaluable patients, 57.2% achieved SVR12 (49.5% monoinfected, 78.9% coinfected). HIV coinfection was associated with a slight increase in the probability of SVR12 (adjusted odds ratio 1.66, 95% confidence interval 0.59-4.64, P=0.33). Premature discontinuation rates and adverse events were similar irrespective of HIV status, with the exception of skin reactions, which were more frequently in the HIV group. In a rea...

An estimated 10-year CVD !10% and/or MS led to the diagnosis of high CV risk. We compared selected clinical features between high-and low-risk patients. Results: A total of 1230 HIV infected patients (72% males, mean age of 43 AE 9 years), 185 of whom treatment-naïve, were evaluated. FRS gave the highest estimate of CV risk. The mean 10-year risk for acute coronary events according to FRS was 7.4 AE 7.0. MS was present in 22% of the observed patients. Accordingly, 443 patients (36%) were classified at high risk. Twelve percent of the patients (n Z 142) had both a FRS !10% and a diagnosis of MS. The main single predictor of increased cardiovascular risk was smoking (60% of whole sample). A higher prevalence of clinically evident lipodystrophy and a higher CD4 T-cell counts were found both in patients with higher FRS and in patients with high FRS and MS (both p < 0.001). Conclusions: The worst estimation of CV risk was obtained with the FRS algorithm. Clinical evidence of lipodystrophy and higher CD4 T-cell counts were closely associated to a worse cardiovascular risk profile.

In a real-life setting, with a high proportion of cirrhotic and treatment-experienced patients, the overall SVR12 rate was 57.2%. HIV coinfection was not associated with impaired outcome.

Twenty-four-hour ambulatory blood pressure (BP) is a more accurate and prognostically relevant measure of an individual&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s BP load than office BP, and the ambulatory BP-derived ambulatory arterial stiffness index (AASI) and symmetric AASI (s-AASI) are established cardiovascular risk factors. In the setting of the HIV and HYpertension (HIV-HY) study, an Italian nationwide survey on high BP in HIV infection, 100 HIV-infected patients with high-normal BP or untreated hypertension (72% men, age 48 ± 10 years, BP 142/91 ± 12/7 mmHg) and 325 HIV-negative individuals with comparable age, sex distribution, and office BP (68% men, age 48 ± 10 years, BP 141/90 ± 11/8 mmHg) underwent 24-h ambulatory BP monitoring. Despite having similar office BP, HIV-infected individuals had higher 24-h SBP (130.6 ± 14 vs. 126.4 ± 10 mmHg) and pulse pressure (49.1 ± 9 vs. 45.9 ± 7 mmHg, both P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), and a lower day-night reduction of mean arterial pressure (14.3 ± 9 vs. 16.3 ± 7%, P = 0.025). Both s-AASI and AASI were significantly higher in HIV patients (s-AASI, 0.22 ± 0.18 vs. 0.11 ± 0.15; AASI, 0.46 ± 0.22 vs. 0.29 ± 0.17; both P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001). In a multivariate regression, s-AASI was independently predicted by HIV infection (β = 0.252, P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.001), age, female sex, and 24-h SBP. In HIV patients, s-AASI had an inverse relation with CD4 cell count (Spearman&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s ρ -0.24, P = 0.027). Individuals with HIV infection and borderline or definite hypertension have higher symmetric AASI and 24-h systolic and pulse pressures than HIV-uninfected controls matched by office BP. High ambulatory BP may play a role in the HIV-related increase in cardiovascular risk.

The HERMES (HIV Exposure and Risk of Metabolic Syndrome) study enrolled therapy-naïve patients attending hospitals in the Italian coordination group for the study of allergies and HIV infection (CISAI [Coordinamento Italiano per lo Studio Allergia e Infezione da HIV]) in 2007. It was designed to identify metabolic syndrome (MS) and cardiovascular risk factors. The present analysis is a nested cross-sectional study with a subset of patients examined by carotid ultrasonography. Consecutive antiretroviral therapy-naïve HIV patients attending the facilities involved in the CISAI were included. Their 10-year probability of cardiovascular events was calculated using the Framingham Risk Score (FRS) and three other cardiovascular algorithms (the Global Framingham Risk Score - GFRS, 'Progetto Cuore' and 'SCORE'). Vascular age was estimated using a new model derived from GFRS and was compared with chronological age. The diagnosis of MS was based on the National Cholesterol Education Programme and International Diabetes Federation (IDF) definitions. Subclinical atherosclerosis was determined as ultrasound carotid intima-media thickness >0.9 mm. Out of 140 patients enrolled in the HERMES study by the four centres participating in the nested study, a total of 72 (51.4%) subjects, with no overt cardiovascular disease, were examined using carotid ultrasonography. The median age was 40 years, 79.2% men. The vascular age was 7.6 years higher than the chronological age. The factors associated with subclinical atherosclerosis were age (P < 0.0001), vascular age (P = 0.0002), body mass index (P = 0.003), waist circumference (P = 0.0002), MS (IDF definition, P = 0.004) and all the cardiovascular (CV) models (FRS, P = 0.01, GFRS, P = 0.002, Progetto Cuore, P = 0.018, SCORE, P = 0.03). Independent of other significant factors, waist circumference was significantly associated with pathological results (P = 0.007). The GFRS (area under the receiver-operating characteristic curves, 0.78; P < 0.001) had slightly better predictive accuracy than the other three CV models (FRS, areas under the curve [AUC] = 0.71, P = 0.003; Progetto Cuore, AUC = 0.74, P = 0.0005; SCORE, AUC = 0.77, P < 0.0001); 55% of patients at intermediate risk (6-20%) had subclinical carotid lesions. Subclinical carotid lesions had a highly significant direct association with all the CV risk predictors. The GFRS and vascular age were highly predictive. We recommend a carotid ultrasonographic examination at least among HIV patients with GFRS > or =6% or with an elevated waist circumference.

However, in the clinical setting NUCs regimens are quite common. The aim of this study was to evaluate the use of NUCS sparing regimens in a cohort of treatment-experienced patients. Methods: The Surveillance Cohort Long-Term Toxicity Antiretrovirals (SCOLTA) Project is a prospective, observational, multicenter study created to assess the incidence of adverse events in patients receiving new antiretroviral drugs raltegravir (RAL) and darunavir (DRV), enrolment is still ongoing. Results: Out of 668 patients enrolled in the RAL or DRV cohort, a total of 202 (30.2%) patients were prescribed NUCS sparing regimens. They were based on RAL (57 patients, 28.2%), DRV (14, 6.9%) or DRV/RAL (131, 64.8%). Patients' baseline characteristics were: 69.0% males, 92.2% Caucasian, 38.3% stage C, 38.9% lipodistrophy, 37.3% HCV coinfected. At the enrolment, the median age was 46 years (20-78), and the median duration of HIV treatment was 12.4 years (range 0-21); median CD4+ were 361 cells/mmc (range 6-1318), median HIV-RNA 3.3 log 10 (range 0.9-6.1). Only 3 patients were naïve at enrolment date. From 2005 to 2010 we identified an increase of NUCs sparing schemes (5.9% to 30.6%) (p=0.001). DRV/ritonavir plus RAL is the most prescribed regimen (33,1%). Comparison between patients on NUCS regimens and patients treated with backbone showed a significant difference in the proportion of HCV-coinfection: 36.6% and 26.2% respectively (p=0.005).

The present cross-sectional analysis aims to assess the baseline prevalence and characteristics of Metabolic Syndrome (MS) in a population of HIV-positive treatment-naïve patients. MS was diagnosed using the National Cholesterol Education Program (NCEP) definitions. A total of 292 subjects were enrolled, median age was 37 years, 75% of them were males. The prevalence of MS was 12.3%. The most frequent trio of abnormalities that led to the diagnosis of MS was high blood pressure, triglycerides and HDL. Univariate analysis showed that MS was associated with the following variables: age, education, physical activity, advanced HIV disease (CDC stage C or HIV-RNA &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;100,000 copies + CD4 &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;100 cells/mm(3)). Higher educational levels remained protectively associated with MS in multivariate analysis. A higher risk of MS was also associated with advanced HIV disease. Actually, treatment-naïve HIV-positive patients in an advanced stage of the disease have a higher prevalence of abnormal levels of triglycerides, HDL cholesterol and blood glucose than those at a less advanced stage. These findings of the HERMES study suggest, therefore, that HIV infection per se is associated to MS.

Muscle alterations ranging from asymptomatic creatine phosphokinase (CPK) increases to rhabdomyol... more Muscle alterations ranging from asymptomatic creatine phosphokinase (CPK) increases to rhabdomyolysis and central nervous system (CNS) symptoms have been reported in patients receiving raltegravir. Muscle symptoms and CPK increases were investigated in a cohort of HIV-infected patients receiving raltegravir-based antiretroviral therapy, and possible associated predictors were evaluated. The SCOLTA Project is a prospective, observational, multicentre study created to assess the incidence of adverse events in patients receiving new antiretroviral drugs in clinical practice. In total, 496 HIV-infected patients were enrolled [333 (67.1%) male]. CDC stage was C in 196 patients (39.5%). Mean age at enrolment was 45.9±9.3 years. Median follow-up was 21 months. Twenty-six patients (5.2%) reported muscle symptoms (16 muscle pain and 17 weakness; 7 had both). Of 342 patients with normal baseline CPK values, 72 (21.1%) had a CPK increase. Seven patients (1.4%) discontinued raltegravir because of muscular events (three for muscle pain/weakness and four CPK increases). No cases of rhabdomyolysis were observed. Patients with muscle symptoms were more frequently receiving in their regimen than those not receiving atazanavir (P=0.04) and were more likely to also report CNS symptoms (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.0001). Significant predictors of muscle symptoms were CNS symptoms and use of atazanavir. Female sex was associated with a reduced risk of CPK increase. In conclusion, muscle symptoms and CPK elevations occurred frequently and caused most discontinuations due to adverse events. Their monitoring in patients receiving raltegravir should be considered, especially when co-administered with atazanavir or when CNS symptoms are also present.

All consecutive naïve patients with CD4 cell count&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;200/mL starting any PI/r-based or NNRTI-based + 2 NRTIs regimen from January 2010 to January 2013 in the participant centres were enrolled. At baseline and after 3 (T1), 6 (T2) and 12 (T3) months patients were subjected to epi-aortic vessels ultrasonography and brachial artery flow mediated dilation (FMD). Viral load, CD4+ cell count, serum lipid values, serum glucose, endothelial activation (ICAM-1 and VCAM-1) and inflammatory markers (IL-6 and hsCRP) values were recorded at the same time. Data about independent risk factors for HIV infection and CV disease are taken at time 0. We enrolled 94 patients: 81% males, 87% caucasians, 40% smokers, 8.2% HCV co-infected and 3.5% with lipodystrophy; 33% of them were homosexuals, 12% drug addicts; 23% were AIDS at presentation. Statistical data analysis has been conducted by the χ(2) nonparametric method. In Table 1 it is reported the percentage of patients with pathologic values, moreover, at T3, 60.46% showed undetectable viraemia and 69.77% had CD4 + &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 200. Our data evidence at baseline has a relevant deterioration of CV conditions in terms of ultrasonographic data, FMD, inflammation and cytokine markers among advanced naïves. During follow-up epi-aortic lesions tend to worsen but not significantly, percentage of pathologic FMD remains stable. Regarding markers of endothelial activation ICAM-1 significantly worsens during the period of observation; also VCAM-1 has a trend towards the worsening while not significantly. Conversely, a significant improvement was observed for the markers of inflammation D-dimers and high sensitivity C-reactive protein (hsCRP). IL-6 improved but not significantly. Serum lipid profile shows an increase of HDLc and total cholesterol, but not of LDLc. In conclusion, after a twelve-month follow-up period, CV risk of the patients remains high. ARV therapy seems in fact to improve only non-specific and poor sensitive inflammation biomarkers and HDLc; markers of endothelial activations tend to worsen, intima-media ultrasonography and FMD do not show relevant modifications. Further data are warranted to better understand the role of the different ARV regimens.

The Surveillance Cohort Long-Term Toxicity Antiretrovirals (SCOLTA) project is a prospective, observational, multicenter cohort created to assess the incidence of adverse events in patients receiving new antiretroviral drugs. Twenty-five Italian infectious diseases centers enroll patients and collect their data through this on-line system. Periodical evaluations of these patients, including physical examination and laboratory tests, were performed at baseline and every 6 months. Four hundred and twenty-nine patients were enrolled since May 2006. Eighty-five patients (19.8%) were prescribed once-daily DRV/r; 31 of them were treatment-naïve (36.5%). Among 54 (63.5%) treatment-experienced patients, 21 (38.9%) had undetectable viral load and started once-daily DRV/r as a simplification regimen. Patients on twice-daily regimen were older, more frequently lipodystrophic, HCV-coinfected, and in CDC stage C. In the following 24 months of follow-up, the viral load steadily decreased as well as the CD4 cell count rose. The reason for discontinuation did not significantly differ between groups. Mean blood glucose (BG) change from baseline did not show significant difference between groups, as well as high density lipoprotein cholesterol (HDL-C), triglycerides (TGL) and alanine transaminase (ALT). The survival curve shows that patients in the once-daily regimen withdrew treatment more frequently than those on twice-daily regimen (Log Rank Chi(2)P=0.009). Our study showed that DRV/r administrated both once daily or twice daily was safe and well tolerated with few discontinuations due to adverse events.

The reproducibility of this finding in an independent dataset was explored and plausible biological mechanisms were sought. Biomarkers, ischemic changes on the electrocardiogram, and rates of various predefined types of cardiovascular disease (CVD) events according to NRTIs used were explored in the Strategies for Management of Anti-Retroviral Therapy (SMART) study. Patients receiving abacavir and not didanosine were compared with those receiving didanosine, and to those receiving NRTIs other than abacavir or didanosine (other NRTIs). Patients randomly assigned to the continuous antiretroviral therapy arm of SMART were included in all analyses (N = 2752); for the study of biomarkers, patients from the antiretroviral therapy interruption arm were also included. Current use of abacavir was associated with an excess risk of CVD compared with other NRTIs. Adjusted hazard ratios for clinical myocardial infarction (n = 19), major CVD (myocardial infarction, stroke, surgery for coronary artery disease, and CVD death; n = 70), expanded CVD (major CVD plus congestive heart failure, peripheral vascular disease, coronary artery disease requiring drug treatment, and unwitnessed deaths; n = 112) were 4.3 [95% confidence interval (CI): 1.4-13.0], 1.8 (1.0-3.1), and 1.9 (1.3-2.9). At baseline in a subset of patients with biomarker data, high sensitivity-C-reactive protein and interleukin-6 were 27% (P = 0.02) and 16% (P = 0.02) higher for patients receiving abacavir (N = 175) compared with those receiving other NRTIs (N = 500). Didanosine was associated neither with altered risk of CVD nor with altered levels of biomarkers. Abacavir was associated with an increased risk of CVD. The drug may cause vascular inflammation, which may precipitate a CVD event.

The aim of this study was to assess the effectiveness of telaprevir-based and boceprevir-based treatments with respect to the HIV status. A prospective multicentre study was conducted among 22 Infectious Disease centres in Italy. Demographic, HIV and HCV related variables were collected, as well as data on HCV viral decay, sustained virologic response (SVR12) and grade 3-4 adverse events. Overall, 162 patients (24.7% HIV/HCV coinfected) received HCV treatment. Out of 145 evaluable patients, 57.2% achieved SVR12 (49.5% monoinfected, 78.9% coinfected). HIV coinfection was associated with a slight increase in the probability of SVR12 (adjusted odds ratio 1.66, 95% confidence interval 0.59-4.64, P=0.33). Premature discontinuation rates and adverse events were similar irrespective of HIV status, with the exception of skin reactions, which were more frequently in the HIV group. In a rea...

An estimated 10-year CVD !10% and/or MS led to the diagnosis of high CV risk. We compared selected clinical features between high-and low-risk patients. Results: A total of 1230 HIV infected patients (72% males, mean age of 43 AE 9 years), 185 of whom treatment-naïve, were evaluated. FRS gave the highest estimate of CV risk. The mean 10-year risk for acute coronary events according to FRS was 7.4 AE 7.0. MS was present in 22% of the observed patients. Accordingly, 443 patients (36%) were classified at high risk. Twelve percent of the patients (n Z 142) had both a FRS !10% and a diagnosis of MS. The main single predictor of increased cardiovascular risk was smoking (60% of whole sample). A higher prevalence of clinically evident lipodystrophy and a higher CD4 T-cell counts were found both in patients with higher FRS and in patients with high FRS and MS (both p < 0.001). Conclusions: The worst estimation of CV risk was obtained with the FRS algorithm. Clinical evidence of lipodystrophy and higher CD4 T-cell counts were closely associated to a worse cardiovascular risk profile.

In the setting of the HIV and HYpertension (HIV-HY) study, an Italian nationwide survey on high BP in HIV infection, 100 HIV-infected patients with high-normal BP or untreated hypertension (72% men, age 48 ± 10 years, BP 142/91 ± 12/7 mmHg) and 325 HIV-negative individuals with comparable age, sex distribution, and office BP (68% men, age 48 ± 10 years, BP 141/90 ± 11/8 mmHg) underwent 24-h ambulatory BP monitoring. Despite having similar office BP, HIV-infected individuals had higher 24-h SBP (130.6 ± 14 vs. 126.4 ± 10 mmHg) and pulse pressure (49.1 ± 9 vs. 45.9 ± 7 mmHg, both P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), and a lower day-night reduction of mean arterial pressure (14.3 ± 9 vs. 16.3 ± 7%, P = 0.025).

Individuals with HIV infection and borderline or definite hypertension have higher symmetric AASI and 24-h systolic and pulse pressures than HIV-uninfected controls matched by office BP. High ambulatory BP may play a role in the HIV-related increase in cardiovascular risk.

The HERMES (HIV Exposure and Risk of Metabolic Syndrome) study enrolled therapy-naïve patients attending hospitals in the Italian coordination group for the study of allergies and HIV infection (CISAI [Coordinamento Italiano per lo Studio Allergia e Infezione da HIV]) in 2007. It was designed to identify metabolic syndrome (MS) and cardiovascular risk factors. The present analysis is a nested cross-sectional study with a subset of patients examined by carotid ultrasonography. Consecutive antiretroviral therapy-naïve HIV patients attending the facilities involved in the CISAI were included. Their 10-year probability of cardiovascular events was calculated using the Framingham Risk Score (FRS) and three other cardiovascular algorithms (the Global Framingham Risk Score - GFRS, 'Progetto Cuore' and 'SCORE'). Vascular age was estimated using a new model derived from GFRS and was compared with chronological age. The diagnosis of MS was based on the National Cholesterol Education Programme and International Diabetes Federation (IDF) definitions. Subclinical atherosclerosis was determined as ultrasound carotid intima-media thickness >0.9 mm. Out of 140 patients enrolled in the HERMES study by the four centres participating in the nested study, a total of 72 (51.4%) subjects, with no overt cardiovascular disease, were examined using carotid ultrasonography. The median age was 40 years, 79.2% men. The vascular age was 7.6 years higher than the chronological age. The factors associated with subclinical atherosclerosis were age (P < 0.0001), vascular age (P = 0.0002), body mass index (P = 0.003), waist circumference (P = 0.0002), MS (IDF definition, P = 0.004) and all the cardiovascular (CV) models (FRS, P = 0.01, GFRS, P = 0.002, Progetto Cuore, P = 0.018, SCORE, P = 0.03). Independent of other significant factors, waist circumference was significantly associated with pathological results (P = 0.007). The GFRS (area under the receiver-operating characteristic curves, 0.78; P < 0.001) had slightly better predictive accuracy than the other three CV models (FRS, areas under the curve [AUC] = 0.71, P = 0.003; Progetto Cuore, AUC = 0.74, P = 0.0005; SCORE, AUC = 0.77, P < 0.0001); 55% of patients at intermediate risk (6-20%) had subclinical carotid lesions. Subclinical carotid lesions had a highly significant direct association with all the CV risk predictors. The GFRS and vascular age were highly predictive. We recommend a carotid ultrasonographic examination at least among HIV patients with GFRS > or =6% or with an elevated waist circumference.

However, in the clinical setting NUCs regimens are quite common. The aim of this study was to evaluate the use of NUCS sparing regimens in a cohort of treatment-experienced patients. Methods: The Surveillance Cohort Long-Term Toxicity Antiretrovirals (SCOLTA) Project is a prospective, observational, multicenter study created to assess the incidence of adverse events in patients receiving new antiretroviral drugs raltegravir (RAL) and darunavir (DRV), enrolment is still ongoing. Results: Out of 668 patients enrolled in the RAL or DRV cohort, a total of 202 (30.2%) patients were prescribed NUCS sparing regimens. They were based on RAL (57 patients, 28.2%), DRV (14, 6.9%) or DRV/RAL (131, 64.8%). Patients' baseline characteristics were: 69.0% males, 92.2% Caucasian, 38.3% stage C, 38.9% lipodistrophy, 37.3% HCV coinfected. At the enrolment, the median age was 46 years (20-78), and the median duration of HIV treatment was 12.4 years (range 0-21); median CD4+ were 361 cells/mmc (range 6-1318), median HIV-RNA 3.3 log 10 (range 0.9-6.1). Only 3 patients were naïve at enrolment date. From 2005 to 2010 we identified an increase of NUCs sparing schemes (5.9% to 30.6%) (p=0.001). DRV/ritonavir plus RAL is the most prescribed regimen (33,1%). Comparison between patients on NUCS regimens and patients treated with backbone showed a significant difference in the proportion of HCV-coinfection: 36.6% and 26.2% respectively (p=0.005).

The present cross-sectional analysis aims to assess the baseline prevalence and characteristics of Metabolic Syndrome (MS) in a population of HIV-positive treatment-naïve patients. MS was diagnosed using the National Cholesterol Education Program (NCEP) definitions. A total of 292 subjects were enrolled, median age was 37 years, 75% of them were males. The prevalence of MS was 12.3%. The most frequent trio of abnormalities that led to the diagnosis of MS was high blood pressure, triglycerides and HDL. Univariate analysis showed that MS was associated with the following variables: age, education, physical activity, advanced HIV disease (CDC stage C or HIV-RNA &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;100,000 copies + CD4 &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;100 cells/mm(3)). Higher educational levels remained protectively associated with MS in multivariate analysis. A higher risk of MS was also associated with advanced HIV disease. Actually, treatment-naïve HIV-positive patients in an advanced stage of the disease have a higher prevalence of abnormal levels of triglycerides, HDL cholesterol and blood glucose than those at a less advanced stage. These findings of the HERMES study suggest, therefore, that HIV infection per se is associated to MS.

Muscle symptoms and CPK increases were investigated in a cohort of HIV-infected patients receiving raltegravir-based antiretroviral therapy, and possible associated predictors were evaluated. The SCOLTA Project is a prospective, observational, multicentre study created to assess the incidence of adverse events in patients receiving new antiretroviral drugs in clinical practice. In total, 496 HIV-infected patients were enrolled [333 (67.1%) male]. CDC stage was C in 196 patients (39.5%). Mean age at enrolment was 45.9±9.3 years. Median follow-up was 21 months. Twenty-six patients (5.2%) reported muscle symptoms (16 muscle pain and 17 weakness; 7 had both). Of 342 patients with normal baseline CPK values, 72 (21.1%) had a CPK increase. Seven patients (1.4%) discontinued raltegravir because of muscular events (three for muscle pain/weakness and four CPK increases). No cases of rhabdomyolysis were observed. Patients with muscle symptoms were more frequently receiving in their regimen than those not receiving atazanavir (P=0.04) and were more likely to also report CNS symptoms (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.0001). Significant predictors of muscle symptoms were CNS symptoms and use of atazanavir. Female sex was associated with a reduced risk of CPK increase. In conclusion, muscle symptoms and CPK elevations occurred frequently and caused most discontinuations due to adverse events. Their monitoring in patients receiving raltegravir should be considered, especially when co-administered with atazanavir or when CNS symptoms are also present.

All consecutive naïve patients with CD4 cell count&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;200/mL starting any PI/r-based or NNRTI-based + 2 NRTIs regimen from January 2010 to January 2013 in the participant centres were enrolled. At baseline and after 3 (T1), 6 (T2) and 12 (T3) months patients were subjected to epi-aortic vessels ultrasonography and brachial artery flow mediated dilation (FMD). Viral load, CD4+ cell count, serum lipid values, serum glucose, endothelial activation (ICAM-1 and VCAM-1) and inflammatory markers (IL-6 and hsCRP) values were recorded at the same time. Data about independent risk factors for HIV infection and CV disease are taken at time 0. We enrolled 94 patients: 81% males, 87% caucasians, 40% smokers, 8.2% HCV co-infected and 3.5% with lipodystrophy; 33% of them were homosexuals, 12% drug addicts; 23% were AIDS at presentation. Statistical data analysis has been conducted by the χ(2) nonparametric method. In Table 1 it is reported the percentage of patients with pathologic values, moreover, at T3, 60.46% showed undetectable viraemia and 69.77% had CD4 + &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; 200. Our data evidence at baseline has a relevant deterioration of CV conditions in terms of ultrasonographic data, FMD, inflammation and cytokine markers among advanced naïves. During follow-up epi-aortic lesions tend to worsen but not significantly, percentage of pathologic FMD remains stable. Regarding markers of endothelial activation ICAM-1 significantly worsens during the period of observation; also VCAM-1 has a trend towards the worsening while not significantly. Conversely, a significant improvement was observed for the markers of inflammation D-dimers and high sensitivity C-reactive protein (hsCRP). IL-6 improved but not significantly. Serum lipid profile shows an increase of HDLc and total cholesterol, but not of LDLc. In conclusion, after a twelve-month follow-up period, CV risk of the patients remains high. ARV therapy seems in fact to improve only non-specific and poor sensitive inflammation biomarkers and HDLc; markers of endothelial activations tend to worsen, intima-media ultrasonography and FMD do not show relevant modifications. Further data are warranted to better understand the role of the different ARV regimens.

The Surveillance Cohort Long-Term Toxicity Antiretrovirals (SCOLTA) project is a prospective, observational, multicenter cohort created to assess the incidence of adverse events in patients receiving new antiretroviral drugs. Twenty-five Italian infectious diseases centers enroll patients and collect their data through this on-line system. Periodical evaluations of these patients, including physical examination and laboratory tests, were performed at baseline and every 6 months. Four hundred and twenty-nine patients were enrolled since May 2006. Eighty-five patients (19.8%) were prescribed once-daily DRV/r; 31 of them were treatment-naïve (36.5%). Among 54 (63.5%) treatment-experienced patients, 21 (38.9%) had undetectable viral load and started once-daily DRV/r as a simplification regimen. Patients on twice-daily regimen were older, more frequently lipodystrophic, HCV-coinfected, and in CDC stage C. In the following 24 months of follow-up, the viral load steadily decreased as well as the CD4 cell count rose. The reason for discontinuation did not significantly differ between groups. Mean blood glucose (BG) change from baseline did not show significant difference between groups, as well as high density lipoprotein cholesterol (HDL-C), triglycerides (TGL) and alanine transaminase (ALT). The survival curve shows that patients in the once-daily regimen withdrew treatment more frequently than those on twice-daily regimen (Log Rank Chi(2)P=0.009). Our study showed that DRV/r administrated both once daily or twice daily was safe and well tolerated with few discontinuations due to adverse events.

The reproducibility of this finding in an independent dataset was explored and plausible biological mechanisms were sought. Biomarkers, ischemic changes on the electrocardiogram, and rates of various predefined types of cardiovascular disease (CVD) events according to NRTIs used were explored in the Strategies for Management of Anti-Retroviral Therapy (SMART) study. Patients receiving abacavir and not didanosine were compared with those receiving didanosine, and to those receiving NRTIs other than abacavir or didanosine (other NRTIs). Patients randomly assigned to the continuous antiretroviral therapy arm of SMART were included in all analyses (N = 2752); for the study of biomarkers, patients from the antiretroviral therapy interruption arm were also included. Current use of abacavir was associated with an excess risk of CVD compared with other NRTIs. Adjusted hazard ratios for clinical myocardial infarction (n = 19), major CVD (myocardial infarction, stroke, surgery for coronary artery disease, and CVD death; n = 70), expanded CVD (major CVD plus congestive heart failure, peripheral vascular disease, coronary artery disease requiring drug treatment, and unwitnessed deaths; n = 112) were 4.3 [95% confidence interval (CI): 1.4-13.0], 1.8 (1.0-3.1), and 1.9 (1.3-2.9). At baseline in a subset of patients with biomarker data, high sensitivity-C-reactive protein and interleukin-6 were 27% (P = 0.02) and 16% (P = 0.02) higher for patients receiving abacavir (N = 175) compared with those receiving other NRTIs (N = 500). Didanosine was associated neither with altered risk of CVD nor with altered levels of biomarkers. Abacavir was associated with an increased risk of CVD. The drug may cause vascular inflammation, which may precipitate a CVD event.
