Objectives: The aim of this study was to assess the incidence of being overweight and metabolic syndrome (MS) among people living with HIV (PHIV) in three different cross-sectional studies conducted over three different periods: 2005, 2011 and 2015. Methods: This was a multi-centre, nationwide study. Data were collected in three studies from the CISAI group - SIMOne, HIV-HY and STOPSHIV - and included a total of 3014 PHIV. Logistic regression [odds ratio (OR), 95% confidence interval (CI)] was used to account for age and gender difference among three groups when comparing MS prevalence and being overweight; potential confounders were accounted for by including them in the regression equation. Results: Overall, the mean age was 46.9±10.2years, and men comprised 73.3% of participants. Comparing 2005, 2011 and 2015, MS was present in 34.5%, 33.0% and 29.3% of PHIV, respectively. Adjusted OR for MS was 0.64 (95% CI: 0.52-0.78) in 2011 and 0.56 (95% CI: 0.46-0.69) in 2015 compared with 2005, while BMI (kg/m2 ) increased from 23.6 in 2005, 24.5 in 2011 and 24.5 in 2015, with a concomitant increase of being overweight from 29.4% to 39.5% to 39.6% (p&nbsp

The role of viruses in community acquired pneumonia (CAP) has been largely underestimated in the pre‐coronavirus disease 2019 age. However, during flu seasonal early identification of viral infection in CAP is crucial to guide treatment and in‐hospital management. Though recommended, the routine use of nasopharyngeal swab (NPS) to detect viral infection has been poorly scaled‐up, especially in the emergency department (ED). This study sought to assess the prevalence and associated clinical outcomes of viral infections in patients with CAP during peak flu season. In this retrospective, observational study adults presenting at the ED of our hospital (Rome, Italy) with CAP from January 15th to February 22th, 2019 were enrolled. Each patient was tested on admission with Influenza rapid test and real time multiplex assay. Seventy five consecutive patients were enrolled. 30.7% (n = 23) tested positive for viral infection. Of these, 52.1% (n = 12) were H1N1/FluA. 10 patients had multiple virus co‐infections. CAP with viral infection did not differ for any demographic, clinic and laboratory features by the exception of CCI and CURB‐65. All intra‐ED deaths and mechanical ventilations were recorded among CAP with viral infection. Testing only patients with CURB‐65 score ≥2, 10 out of 12 cases of H1N1/FluA would have been detected saving up to 40% tests. Viral infection occurred in one‐third of CAP during flu seasonal peak 2019. Since not otherwise distinguishable, NPS is so far the only reliable mean to identify CAP with viral infection. Testing only patients with moderate/severe CAP significantly minimize the number of tests., Highlights This study stresses the incidence of viral pneumonia during the flu season and underlies the role of viral infection screening at the ED regardless of the current COVID‐19 pandemic.

OBJECTIVES The aim of the study was to analyse the prevalence of integrase resistance mutations in integrase strand transfer inhibitor (INSTI)-experienced HIV-1-infected patients and its predictors. METHODS We selected HIV-1 integrase sequences from the Antiviral Response Cohort Analysis (ARCA) database, derived from INSTI-experienced patients between 2008 and 2017. Differences in the prevalence of resistance to raltegravir (RAL), elvitegravir (EVG) and dolutegravir (DTG) were assessed by χ2 test and predictors of resistance were analysed by logistic regression. RESULTS We included 462 genotypes from INSTI-exposed individuals: 356 'INSTI-failing' patients and 106 'previously INSTI-exposed' patients (obtained a median of 42 weeks after INSTI discontinuation [interquartile range (IQR) 17-110 weeks]). Overall, at least low-level resistance (LLR) to any INSTI (Stanford 8.5 algorithm) was detected in 198 (42.9%) cases. The most frequent INSTI resistance mutation was N155H, followed by Q148H/K/R, G140A/C/S, E138A/K/T and Y143C/H/R. Y143R and E138A were more prevalent in viral subtype B versus non-B [5.2 versus 1.5%, respectively (P = 0.04), and 3.1 versus 0%, respectively (P = 0.02)]. Overall, the Q148H/K/R plus G140A/C/S and/or E138A/K/T pattern, defining an intermediate level of resistance to DTG, was detected in 70 (15%) cases. Independent predictors of at least LLR to any INSTI were current use versus past use of INSTIs, a lower genotypic sensitivity score (GSS) for contemporary antiretroviral drugs used, and having an integrase sequence obtained in calendar year 2016 as compared to 2008-2009. CONCLUSIONS The results support integrase resistance testing in INSTI-experienced patients. Emergence of INSTI resistance is facilitated by the reduced genetic barrier of the regimen as a consequence of resistance to companion drugs. However, INSTI resistance may become undetectable by standard population sequencing upon INSTI discontinuation.

Background: In a 2013 survey, we reported distinct discrepancies in delivery of tuberculosis (TB) and HIV services in eastern Europe (EE) vs. western Europe (WE). Objectives: To verify the differences in TB and HIV services in EE vs. WE. Methods: Twenty-three sites completed a survey in 2018 (EE, 14; WE, nine; 88% response rate). Results were compared across as well as within the two regions. When possible, results were compared with the 2013 survey. Results: Delivery of healthcare was significantly less integrated in EE: provision of TB and HIV services at one site (36% in EE vs. 89% in WE; P = 0.034), and continued TB follow-up in one location (42% vs. 100%; P = 0.007). Although access to TB diagnostics, standard TB and HIV drugs was generally good, fewer sites in EE reported unlimited access to rifabutin/multi-drug-resistant TB (MDR-TB) drugs, HIV integrase inhibitors and opioid substitution therapy (OST). Compared with 2013, routine usage of GeneXpert was more common in EE in 2018 (54% vs. 92%; P = 0.073), as was access to moxifloxacin (46% vs. 91%; P = 0.033), linezolid (31% vs. 64%; P = 0.217), and bedaquiline (0% vs. 25%; P = 0.217). Integration of TB and HIV services (46% vs. 39%; P = 1.000) and provision of OST to patients with opioid dependency (54% vs. 46%; P = 0.695) remained unchanged. Conclusion: Delivery of TB and HIV healthcare, including integration of TB and HIV care and access to MDR-TB drugs, still differs between WE and EE, as well as between individual EE sites.

The use of hydroxychloroquine (HCQ) has been considered a therapeutic option by international guidelines and expert opinions during the first phase of COVID‐19 pandemics, 1‐10 although scientific evidence remained too scarce to make a definitive recommendation 11. While HCQ use has now been questioned by recent data 7, some previous works draw attention to contrasting results on enhanced viral clearance after HCQ treatment 1‐6,10.

OBJECTIVES The aim of the study was to investigate the organization and delivery of HIV and tuberculosis (TB) health care and to analyse potential differences between treatment centres in Eastern (EE) and Western Europe (WE). METHODS Thirty-eight European HIV and TB treatment centres participating in the TB:HIV study within EuroCoord completed a survey on health care management for coinfected patients in 2013 (EE: 17 respondents; WE:21; 76% of all TB:HIV centres). Descriptive statistics were obtained for regional comparisons. The reported data on health care strategies were compared with actual clinical practice at patient level via data derived from the TB:HIV study. RESULTS Respondent centres in EE comprised: Belarus (n = 3), Estonia (1), Georgia (1), Latvia (1), Lithuania (1), Poland (4), Romania (1), the Russian Federation (4) and Ukraine (1); those in WE comprised: Belgium (1), Denmark (1), France (1), Italy (7), Spain (2), Switzerland (1) and UK (8). Compared with WE, treatment of HIV and TB in EE are less often located at the same site (47% in EE versus 100% in WE; P

The factors influencing virological response to first-line combined antiretroviral therapy (cART) in an Italian cohort of HIV-1-infected patients were examined. Eligible patients were those enrolled in a national prospective observational cohort (Antiretroviral Resistance Cohort Analysis), starting first-line cART between 2001 and 2011 and who had at least one follow-up of HIV-1 RNA. The primary endpoint was virological success, defined as the first viral load 100,000 copies/ml, virologic success was only associated with the use of integrase inhibitors in the first cART regimen. Independent predictors of immunological success were baseline CD4+ cell count and wGSS

Objectives- To investigate common carotid intima-media thickness in a cohort of patients who were vertically infected with human immunodeficiency virus 1 (HIV-1). Methods- We conducted a cross-sectional observational study. Human immunodeficiency virus 1-infected patients were compared with age-, sex-, and body mass index-matched healthy participants. Common carotid intima-media thickness was measured in all participants on both sides of the neck, and the mean intima-media thickness was calculated. Metabolic parameters and markers of inflammation were measured only in HIV-1-infected patients. Statistical analysis was performed by multiple regression and by a matrix of Pearson correlation coefficients. The Student t test was used to compare mean common carotid intima-media thickness values between groups. Results- Forty patients (21 female) with HIV-1 infection acquired from birth with a mean age ± SD of 16.3 ± 4.7 years and 27 healthy participants (11 female) with a mean age of 17.7 ± 4.6 years were included in the study. Mean common carotid intima-media thickness in the HIV-1-infected group (0.450 ± 0.088 mm) was significantly higher (P < .05) than in the control group (0.407 ± 0.079 mm). No significant association was found between intima-media thickness and a specific antiretroviral regimen, exposure to combined antiretroviral agents, and HIV status. In multiple regression analyses, higher levels of insulin (P= .007) and elevated levels of glycated hemoglobin (P= .01) were associated with intima-media thickness changes. Conclusions- Patients perinatally infected with HIV have increased common carotid intima-media thickness compared with healthy individuals. These changes were more pronounced with increasing age and inflammation markers. Interventions that improve cardiovascular risk profiles should be considered in HIV-infected young adults.

Fetal hemoglobin may be slightly or significantly elevated in post-natal life due to a number of causes. We report two novel mutations found on the promoter of the Aγ gene and summarize all common and rare determinants associated with hereditary persistence of fetal hemoglobin (HPFH) described thus far. Hematological and molecular analysis of the Aγ globin gene in two cases of HPFH. Comparison of the novel cases with all those described in the literature. We have found two novel mutations in three Italian patients with HbF values between 5.9% and 6.5% without an elevated HbA(2) and with normal hemoglobin parameters. In two probands (mother and son), a -197 C>T transition was observed, while in a single individual, a -113 A>G transition was present on the distal CCAAT box of the Aγ gene. As no other abnormalities were present in both γ-gene promoters and the changes are located on regulatory sequences, we may conclude that these mutations are responsible for the HPFH phenotype shown by the carriers. The laboratory should be able to discriminate between elevated HbF due to artifacts or to serious causes including bone marrow malignancies, aplastic anemia, and β-thalassemia major or recessive traits such as β-thalassemia minor, δβ-thalassemia, or nonpathological conditions induced by mutations or polymorphisms of the γ-gene promoters that may even be beneficial when present in patients with thalassemia major or sickle cell disease and, in particular, when these patients are treated with hydroxyurea.

Limited evidence is available currently regarding the efficacy and safety of pegylated interferon (PEG-IFN) and ribavirin in patients co-infected perinatally with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). No information is available on whether or not these patients should be treated earlier for infection with HCV. This report describes four patients with HIV and HCV co-infection acquired perinatally, who were treated with PEG-IFN and ribavirin for chronic viral hepatitis caused by HCV.

Objective To review prevention data for hemoglobinopathies from Latium, a large Italian region with a considerable immigrant population and with a well-established regional prevention program. Method All data pertaining to population screening for hemoglobinopathies in the Latium region were reviewed for the period 1994–2007. Screening was performed universally in secondary schools and to pregnant couples at the time of prenatal care. We have examined the trends in positive screening results as well as the type of hemoglobinopathies detected during the study period, and we have correlated them to the type of population (immigrant vs indigenous). Results From 1994 to 2007, 167 235 individuals were examined for carrier status for hemoglobinopathies, and 10 353 of them (6.2%) were immigrants. We have registered a threefold increase in rates of screen-positive subjects who belonged to ethnic minorities during the study period (from 2.7% in 1994 to 9.8% in 2007). Over half of the screen-positive subjects (5397/10 353) presented no hematological anomalies, 24% (n = 2472) had iron deficiency, and 24% (n = 2484) was classified as putative carriers. Among the last group, 22.6% were carriers of β-thalassemia, 48% were suspected α-thalassemia carriers, and the remainder had less common hemoglobinopathies. While the prevention program resulted in nearly zero births of autochthonous newborns affected by severe hemoglobinopathies, a rise in number of affected individuals was noted among immigrants. Screening of secondary school students was accepted by 67% of immigrant parents, resulting in 9737 pupils screened between 2002 and 2006. Conclusion Existing preventive programs for severe hemoglobinopathies should adapt to changes in population ethnicities. Screening for hemoglobinopathies at school age is an efficient strategy.

Aims The purpose of the study was to compare the pharmacokinetic parameters of rifabutin obtained in a group of patients without wasting syndrome (NWS) with those obtained in a group with wasting syndrome (WS). Methods A single dose of 300 mg rifabutin was administered in the fasting state to the patients in both study groups and blood samples were scheduled to be collected at the following times: 0 (predose), 0.5, 1, 2, 3, 4, 6, 8, 24, 48, 72 and 96 h following administration. Data were analysed using noncompartmental methods. The pharmacokinetic parameters of rifabutin in patients with and without wasting syndrome were compared using the Mann–Whitney U-test. ResultsCmax was 0.34±0.14 mg l−1 in NWS patients and 0.55±0.16 mg l−1 (P=0.01) in patients with WS. tmax was 4.2±1.5 and 3.3±2.3 h (P=0.17) in NWS and WS patients, respectively. The AUCs were similar in the two study groups. V/F was 2905±1646 l in NWS patients and 1701±492 l (P=0.07) for the WS group. These differences are less pronounced following normalization of V/F to patients body weight (43.7±20.1 vs 35.4±10.3 l kg−1 ). t1/2,λz tended to be shorter in patients with WS (31.4±12.9 vs 46.0±23.5 h, P=0.12). Conclusions Our study suggests that the pharmacokinetics of rifabutin in patients with wasting syndrome are not altered to a degree that is clinically important.

Purpose of the study : Since X4/DM HIV-1 tropism is associated with poorer prognosis and worse response to treatment, the aim of this study was to assess whether X4/DM HIV-1 tropism is also related with a higher accumulation of resistance in patients experiencing treatment failure. Methods: HIV protease (PR) and reverse transcriptase (RT) resistance mutations and tropism test results were extracted from a national database. Viral tropism data included enhanced sensitivity Trofile assay (ESTA) and geno2pheno results at 10% false positive rate. Historical resistance mutations (HRM) for PI, NRTI and NNRTI, detected in all genotypic tests performed during patient treatment history, were selected according to IAS-USA indications. Summary of results: Overall, 1280 patients were included: males 65%, median age 45 years (IQR: 40-50), median CD4 nadir 116 (IQR: 34-272), median past regimens 7 (IQR: 3-12), median previous NRTI used 5 (IQR: 4-7), median previous NNRTI used 1 (IQR 1-2) and median previous PI used 3 (IQR 1-5). HIV tropism was assessed by ESTA in 271 patients (21.2%) and by geno2pheno in 1009 patients (78.8%). Four hundred and fifteen patients (32.4%) carried X4/DM virus and 321 (25.1%) had ≥1 HRM for each antiretroviral class. The mean number of HRM was higher in patients harboring X4/DM virus than in patients harboring R5 virus (5.1±6.4 vs. 4.3±5.9, p=0.02 at ANOVA test). X4/DM strains also harbored a higher mean number of PI-related HRM (1.8±2.8 vs. 1.5±2.6, p=0.003) and NNRTI-related HRM (1.2±1.6 vs. 0.9±1.4, p=0.001), but not of NRTI-related HRM (2.2±2.6 vs. 2.0±2.6). At logistic regression, patients with HRM for all the 3 classes had a significant higher risk of also harboring X4/DM virus (OR: 1.6, 95% CI: 1.0-2.4, p=0.04). Moreover, X4/DM virus was found to be associated with previous use of NNRTI-containing regimens (OR: 1.4, 95% CI: 1.1-1-9, p=0.03) and lower CD4 nadir (OR: 0.9, 95% CI: 0.9-1.0, p=0.001, per 50-CD4 increase). The analysis was adjusted by number of genotypic tests, number of treatment lines, age and HV subtype. Single mutations significantly associated with X4/DM tropism were: for PI, V32I and L76V; for NRTI: M41L, K70R, L74V and T215Y and for NNRTI: E138G and V179T. Conclusions: Our data suggest that X4/DM tropism is associated with accumulation of resistance mutations during treatment history. X4/DM tropism is also confirmed to be a marker of a more compromised clinical and immune-virological condition.

Purpose of the study : Promising research suggest that maraviroc (MVC) has favourable clinical outcome in HIV-infected patients (pts). Aim of the study is to assess: durability, safety profile and immunovirological recovery in a large MVC-based cohort. Methods : All HIV pts treated with antiretroviral therapy (ART) containing MVC for at least 6 months (all viruses CCR-5 tropic analyzed by genotypic and phenotypic test) were recruited in an observational multicenter study. Eight Infectious Diseases Centers in Liguria and Piedmont (Italy) collected at baseline and every 3 months demographics, clinical and immunovirological data on a web-based system (by MedinfoDist, University of Genoa). We used SPSS for Pearson Chi square test and for generalized estimating equation (GEE); in this model for longitudinal data and frequency analysis we considered altered: TCD4+ ≤350/mmc, HIVRNA >50 cp/ml, total cholesterol >200 mg/dl, triglycerides >160 mg/dl, transaminase >40 mg/dl, creatinine >1.3 mg/dl and we divided data in 5 time periods: baseline, 1-6, 9-12, 15-24 and 24-45 months. Summary of results : We enrolled 55 pts: 36 (65%) males, median age 49.6 years (yrs) (range [r] 18.2-76.6, IQR 44.5-53.3), 11 (20%) HCVRNA-positive, 4 (7%) HBsAg-positive, 1 both infection. Twenty-four (44%) pts were classified as CDC C stage, median nadir TCD4+ was 219/mmc (r 11-529, IQR 125-317), median duration of ART was 15.3 yrs (r 1.3-27.3, IQR 12-16.8), median duration of treatment with MVC was 23 months (r 6-47, IQR 14-36). At baseline 42 (76%) pts had HIVRNA >50 cp/ml, 11 (20%) HIVRNA ≤50 cp/ml, 2 (4%) pts no data; on treatment at the last examination 53 pts (96%) had HIVRNA ≤50 cp/ml, 2 pts still had HIVRNA >50 cp/ml (CCR5 tropic) and median TCD4+ count was 469/mmc (r 73-1802, IQR 302-592). One pt died and only 2 pts shifted to X4. Chi square test at 9-12 months showed p=0.0001 and the 80% of pts had TCD4+ >350/mmc; at the same observation time 83.3% of pts had HIVRNA ≤50 cp/ml (p=0.0001). About cholesterol, triglycerides, transaminase and creatinine no significative differences were found and the median value showed no changes. Conclusions : In our study a majority of pts treated with ART containing MVC achieved a count of TCD4 >350/mmc and HIVRNA undetectable within 9-12 months. This regimen is a safe, feasible option and in pts with a poor immunological stage, MVC offered a remarkable TCD4+ count gain with limited X4 strains onset.

Introduction : The introduction of combined antiretroviral treatment (cART) has reduced HIV-associated morbidity and mortality, and changed the patients’ perspective of life. As a result, Health Related Quality of Life (HRQOL) has become a crucial clinical issue. Objective : Assessment of HRQOL in a sample of Italian patients from IANUA study. Investigate correlation between CD4 cell counts, viral load and changes in HRQOL. Materials and Methods : EQ-5D-3L self-reported questionnaire has been used in the evaluation of HRQOL. It assesses five dimensions: “mobility,” “self care,” “usual activities,” “pain/discomfort” and “anxiety/depression.” Each dimension has three levels: no problems, some problems and extreme problems. In addition, it includes a Visual Analogue Scale (VAS) where one's own health “today” is rated from 0 “worst imaginable health” to 100 “best imaginable health.” The respondents provide information on marital status, education, employment/unemployment, other treatments used in addition to HAART (1,2,3,4,5 or more) and number of hospitalizations due to HIV/AIDS. Results : 684 patients completed the questionnaire: 231 females and 453 males. The mean age of the sample was 51 years (range 21–78). The mean VAS score was 69.9. 558 patients (81.5%) reported no problems in mobility. 642 patients (93.5%) had no problems in self care. 423 patients (61.8%) had no pain/discomfort while 219 had some problems. 326 patients (46.1%) had some problems in anxiety/depression. Conclusions : The analysis of self-reported questionnaires indicates that HRQOL in our sample group is not deeply affected by HIV/AIDS. The dimensions that are affected in the least are “mobility” and “self care” while the major problem is “anxiety/depression” with half of the sample reporting moderate or high level.

Introduction : The persistence of immune activation and inflammation in HIV patients with HIV-RNA (VL) undetectable causes many co-morbidities [ 1 – 3 ]. The aim of this study is to correlate monocytes (m) and NK cell activation levels, soluble markers and oxidative stress with clinical, biochemical and metabolic data in HIV-1 infected patients with VL≤50 copies (cp)/mL on antiretroviral therapy. Materials and Methods : Multicentre, cross-sectional study in patients with VL≤50 cp/mL and on antiretroviral therapy by at least six months. We studied: activation/homing markers (CD38, HLA-DR, CCR-2, PDL-1) on inflammatory, intermediate, proinflammatory m; activatory receptors NKp30, NKp46 and HLA-DR on NK cells; soluble inflammatory (sCD14, adiponectina, MCP-1) and stress oxidative markers (dRoms, antiRoms). Univariate analyses are performed with non-parametric and Pearson tests. The significant correlations were adjusted for possible known confounding factors (smoking, Cytomegalovirus IgG serology, Raltegravir, Protease Inhibitor [PI] therapy and HCV-RNA) with multivariate analysis. Results : In the 68 patients the positive correlation between age and antiRoms was significant also after adjustment for PI use (p=0.05). The% CD8+T was associated with% proinflammatory m (p=0.043) and with their expression of CCR2 mean fluorescence intensity (MFI) (p=0.012). The% NKp46+ was positively correlated with CD4+T count (p=0.001). The fibrinogen was positively associated with dRoms (p=0.052) and the positive correlation between triglycerides and antiRoms has been confirmed (p

Background : We assessed the virological response of DRV/r-based dual therapy in drug-experienced patients included in the Italian antiretroviral resistance database (ARCA). Material and Methods : Patients included in the study were treated with DRV/r in association with raltegravir (RAL), etravirine (ETV) or maraviroc (MAR) following treatment failure(s) and with a resistance test and at least one follow-up visit available. Observation was censored at last visit under dual therapy and survival analysis and proportional hazard models were used, taking virological failure (confirmed >50 c/mL HIV-RNA) as the end-point. Results : Of the total 221 patients included, 149 (67.4%) started DRV/r with RAL, 45 (20.4%) with ETV, 27 (12.2%) with MAR. Patients characteristics at the start of dual regimen were as follows: mean number of previous regimens, nine (IQR: 5–13); non-B subtype, 17 (7.7%); median CD4 count, 347 (IQR: 246–544); undetectable viral load, 74 (33.5%). Full DRV/r resistance was detected in one (0.5%, HIV-DB interpretation system), 13 (5.9%, ANRS) and 17 patients (7.7%, Rega). 69 virological failures (31.2%) were observed during follow-up. At survival analysis, the overall proportion of failure was 29.2% at one year and 33.8% at two years. The proportion of failure was lower in patients starting with undetectable versus detectable viral load (13.3% and 25.2% versus 37.4% and 38.8% at one and two years, respectively, p=0.001 for both analyses) and in patients treated with DRV 600 BID versus 800 QD (HR: 0, 56; 95% CI 0.31–0.99; p
