Abstract
In the present study, we aimed to investigate the association between soluble CD40 ligand (sCD40L, a marker of platelet activation), soluble thrombomodulin, and syndecan-1 (both well-described markers of endothelial dysfunction) and metabolic syndrome in a large cohort of well-treated people with HIV (PWH) and to elucidate their association with HIV-specific variables. We included 862 PWH with undetectable viral replication. Our hypotheses were tested using uni- and multivariable logistic regression models a priori adjusted for well-known confounders. While no association of soluble thrombomodulin and syndecan-1 with MetS was found, high levels of sCD40L (aOR 1.54 [1.07-2.22]) were associated with excess risk of MetS. Given the previously described association between sCD40L, vascular inflammation and endothelial damage, the results presented in our study may suggest a potential role for sCD40L in the well-known association between cardiometabolic comorbidity and HIV infection.

Abstract
Introduction People living with HIV (PLWH) are at twice the risk of developing cardiovascular diseases and have more than four times higher odds of aortic aneurysm (AA) than the uninfected population. However, biomarkers of AA in PLWH are yet to be discovered. We aimed to investigate whether circulating biomarkers reflecting platelet activation, hemostasis and endothelial disruption, i.e. sCD40L, D-dimer, syndecan-1, and thrombomodulin, were associated with AA in PLWH. Methods Five hundred seventy one PLWH from the Copenhagen Comorbidity in HIV Infection (COCOMO) study ≥40 years of age with an available contrast-enhanced CT scan as well as available biomarker analyses were included. The biomarkers were analyzed on thawed plasma. For each biomarker, we defined high level as a concentration in the upper quartile and low level as a concentration below the upper quartile. For D-dimer, the cut-off was defined as the lower limit of detection. Using unadjusted and adjusted logistic and linear regression models, we analyzed associations between AA and sCD40L, D-dimer, syndecan-1, and thrombomodulin, respectively in PLWH. Results PLWH had median (IQR) age 52 years (47-60), 88% were male, median (IQR) time since HIV diagnosis was 15 years (8-23), and 565 (99%) were currently on antiretroviral treatment. High level of sCD40L was associated with lower odds of AA in both unadjusted (odds ratio, OR, 0.23 (95% CI 0.07-0.77; P=0.017)) and adjusted models (adjusted OR, aOR, 0.23 (95% CI 0.07-0.78; P=0.019)). Detectable level of D-dimer was associated with higher odds of AA in both unadjusted (OR 2.76 (95% CI 1.34-5.67; P=0.006)) and adjusted models (aOR 2.22 (95% CI 1.02-4.85; P=0.045)). Conclusions SCD40L was associated with lower odds of AA whereas D-dimer was independently associated with higher odds of AA in PLWH. This calls for further investigations into specific biomarkers to aid early diagnosis of AA in PLWH.

Abstract
OBJECTIVES To evaluate the prevalence of carotid intima-media thickness (IMT) and plaques in a cohort of people living with HIV (PLWH), the role of cardiovascular risk factors, the impact of the antiretroviral regimens and the difference between naïve and experienced patients in the onset of carotid lesions. METHODS This project was initiated in 2019 and involves eight Italian centres. Carotid changes were detected using a power colour-Doppler ultrasonography with 7.5 MHz probes. The following parameters were evaluated: IMT of both the right and left common and internal carotids, data regarding risk factors for cardiovascular disease, HIV viral load, CD4 cell counts, serum lipids, glycaemia and body mass index. The associations between pathological findings and potential risk factors were evaluated by logistical regression, with odds ratios (ORs) and 95% confidence intervals (95% CI)s. RESULTS Among 1147 evaluated PLWH, with a mean age of 52 years, 347 (30.2%) had pathological findings (15.8% plaques and 14.5% IMT). Besides the usual risk factors, such as older age, male sex and dyslipidaemia, CD4 cell nadir < 200 cells/mL (adjusted OR = 1.51, 95% CI: 1.14-1.99) and current use of raltegravir (adjusted OR = 1.54, 95% CI: 1.01-2.36) were associated with higher prevalence of pathological findings. CONCLUSIONS Our data show that the current overall percentage of carotid impairments remains high. Colour-Doppler ultrasonography could play a pivotal role in identifying and quantifying atherosclerotic lesions among PLWH, even at a very premature stage, and should be included in the algorithms of comorbidity management of these patients.

Abstract
Introduction: In intensive care units (ICU), patients remain bedridden for a long time. In addition, severe infections are frequently seen in ICUs. Both prolonged immobilization and serious infections are associated with bone tissue loss. The Wnt pathway has recently been focused on evaluating bone tissue loss. The Wnt pathway participates in both infections and the formation of bone tissue. Wnt pathway inhibitors sclerostin and Dickkopf-1 (DKK-1) inhibit bone formation and increase osteoclastic activity. In this study, we aimed to examine bone turnover by the Wnt inhibitors sclerostin and DKK-1 and their possible associations with inflammation in SIRS patients.Methods: We included 30 patients diagnosed with systemic inflammatory response syndrome (SIRS) in the study group and 16 in the control group. Serum sclerostin, DKK-1, white blood cell (WBC), and C-Reactive Protein (CRP) levels on the day of SIRS diagnosis (basal), the 7th, 14th, and 21stdays were evaluated in the study group, and the results were compared with the control group.Results: When the control group was compared with the basal SIRS, there was a significant elevation in both sclerostin (p=0.003) and DKK-1 (p=0.001). Statistical analysis showed significant decreases in sclerostin levels between basal and the 7th, 14th, and 21st days (p=0.033, p=0.003, p=0.002, respectively). Similarly, significant decreases in DKK-1 levels between basal and the 7th and 21st days (p=0.015, p=0.001, respectively) and an insignificant decrease on the 14th day (p=0.191) was observed. Sclerostin was positively and significantly correlated with WBC and CRP in basal and 7th-day measurements and WBC in 7th and 14th days. DKK-1 is positively and significantly correlated with WBC in basal and 7th-daymeasurements, while DKK-1 negatively correlates with CRP in basal-7th-day measurements.Conclusion: In this study, it was shown for the first time that the Wnt antagonists sclerostin and DKK-1 values are high in SIRS patients in ICU. Both biomarker levels decreased in parallel with the treatment. However, it could not be associated with disease severity and inflammatory marker levels. We believe that monitoring the change of Wnt antagonists will be useful in demonstrating bone turnover in patients with SIRS.Keywords: Dickkopf-1, Intensive care unit, Sclerostin, Systemic inflammatory response syndrome, Wnt signaling pathway, Bone turnover

Abstract
BACKGROUND Several algorithms have been developed to predict cardiovascular risk (CVR) over time, however none of them seem to be accurate when applied to HIV patients. OBJECTIVE The aim of this study was to assess plasma inflammatory biomarkers in relation to multiple CVR scores (FRS, ASCVD, PROCAM and the DAD-5 Years-Estimated-Risk) in an Italian cohort of HIV patients undergoing a combined Antiretroviral Therapy (cART). METHODS We enrolled HIV patients undergoing cART without any change in the HIV-related pharmacological therapy over the last 48 weeks Demographic and anamnestic data were collected, and a biochemical panel including the following biomarkers was collected: CRP, Cystatin-C, microalbuminuria, IL-18, IL-2, IL-4, IL-6, IL-10, TNF-α and IFN- γ. CVR scores were obtained for each patient and compared to the biochemical panel to assess statistical correlation. RESULTS 90 Caucasian HIV patients were enrolled. Assessment of CVR scores showed FRS values of 6.98±6.11%, ASCVD 7.18±6.25%, PROCAM 6.7±7.4% and DAD-5 Years Estimated Risk 3.10±3.41%. We found correlations between the levels of circulating cytokines measured and the cardiovascular risk prediction scores. CONCLUSIONS Our data showed that the values of selected inflammatory biomarkers strongly correlate with the CVR scores, suggesting that they can be employed as reliable predictors of cardiovascular disease in HIV patients. The routine use of selected biomarkers associated with systemic inflammation could be a valid and readily available tool for clinicians to assess and monitor cardiovascular risk in HIV patients. .

Abstract
BACKGROUND The improvements in HIV infection therapy and the large availability of antiretroviral drugs have led to an increased survival among HIV infected people, and simultaneously to a raised morbidity and mortality due to not-AIDS-related events in this group compared to the general population. An increased systemic inflammation and a persistent immune activation play a pivotal role in determining high rates of non-AIDS comorbidities. In the last years, many natural or synthetic immunomodulatory molecules acting by different mechanisms have been conceived. Pidotimod is a synthetic dipeptide molecule showing immunomodulatory properties. The aim of this pilot study was to evaluate the effects of Pidotimod supplementation on residual inflammation in HIV infected population. METHODS Forty HIV positive individuals under cART were enrolled: 30 were treated with Pidotimod supplementation (study group) and 10 served as control group (without Pidotimod supplementation). For all participants, Cystatin C, PCR, ESR, microalbuminuria, TNF-α, INF-γ, IL-4, IL-10, IL1β, IL-18 and IL-2 were measured at enrolment (T0), 4 weeks after of Pidotimod supplementation (T1), and 4 weeks after completing supplementation (T2). RESULTS In HIV positive participants treated with Pidotimod, the evaluation of cytokine levels showed that IL-10, IFN gamma, and IL-4 were significantly higher at enrolment compared to the control group. The increase under Pidotimod treatment persisted after supplementation suspension, while the pro-inflammatory cytokines levels were reduced. Salivary IgA also increased during 4 weeks of supplementation and persisted at 4 weeks after completing supplementation. On the other hand, the Cystatin C and microalbuminuria levels decreased over time, at a greater extent the Cystatin C serum levels. CONCLUSION The study findings showed that the HIV population receiving Pidotimod achieved a rebalancing of pro-inflammatory and anti-inflammatory cytokines as well as a significant reduction in cystatin C levels. The treatment further allowed for an increase in salivary IgA levels at all the analyzed times, as a secondary event to a remodulation of the immunological status obtained with pidotimod. This approach could represent a new way to design new intervention strategies aimed at improving the persistent immune activation status in the virologically suppressed HIV population.

Abstract
BACKGROUND Extracellular vesicles, released by cell pullulation, are surrounded by a phospholipid bilayer and carry proteins as well and genetic material. It has been shown that extracellular vesicles mediate intercellular communication in several conditions, such as inflammation, immunodeficiency, tumor growth, and viral infections. Here, we analyzed circulating levels of extracellular vesicles in order to clarify their role in chronic inflammation mechanisms characterizing HIV patients. METHODS We analyzed and subtyped circulating levels of extracellular vesicles, through a recently developed flow cytometry method. In detail, endothelial-derived extracellular vesicles (CD31+/CD41a-/CD45-, EMVs), extracellular vesicles stemming from leukocytes (CD45+, LMVs) and platelets (CD41a+/CD31+) were identified and enumerated. Moreover, we analyzed the extracellular vesicle protein cargo with proteomic analysis. RESULTS Circulating levels of total extracellular vesicles, EMVs and LMVs were significantly lower in the HIV+ patients than in healthy subjects, whereas platelet-derived extracellular vesicles resulted higher in patients than in the healthy population. Proteomic analysis showed the upregulation of gammaIFN and IL1α, and down-regulation of OSM, NF-kB, LIF, and RXRA signaling resulted activated in this patients. CONCLUSION These data demonstrate, for the first time that HIV infection induces the production of extracellular vesicles containing mediators that possibly feed the chronic inflammation and the viral replication. These two effects are connected as the inflammation itself induces the viral replication. We, therefore, hypothesize that HIV infection inhibits the production of extracellular vesicles that carry anti-inflammatory molecules.

Abstract
Systemic biomarkers of inflammation, including cytokines and chemokines, are potentially useful in the management of both HIV infection and non-AIDS-defining disorders. However, relatively little is known about the utility of measurement of circulating biomarkers of platelet activation as a strategy to monitor the efficacy of combination antiretroviral therapy (cART), as well as the persistence of systemic inflammation following virally-suppressive therapy in HIV-infected persons. These issues have been addressed in the current study to which a cohort consisting of 199 HIV-infected participants was recruited, 100 of whom were cART-naïve and the remainder cART-treated and virally-suppressed. Fifteen healthy control participants were included for comparison. The study focused on the effects of cART on the responsiveness of three biomarkers of platelet activation, specifically soluble CD40 ligand (sCD40L), sCD62P (P-selectin), and platelet-derived growth factor-BB (PDGF-BB), measured using multiplex suspension bead array technology. Most prominently sCD40L in particular, as well as sCD62P, were significantly elevated in the cART-naïve group relative to both the cART-treated and healthy control groups. However, levels of PDGF-BB were of comparable magnitude in both the cART-naïve and -treated groups, and significantly higher than those of the control group. Although remaining somewhat higher in the virally-suppressed group relative to healthy control participants, these findings identify sCD40L, in particular, as a potential biomarker of successful cART, while PDGF-BB may be indicative of persistent low-level antigenemia.

Abstract
The risk of venous thromboembolism (VTE) and of recurrent VTE remain elevated in people living with HIV compared to controls still with contemporary antiretroviral therapy (ART). The pathophysiology of VTE in HIV is multi factorial and includes an interplay among traditional risk factors, HIV-specific factors, behavioral factors, exposure to ART and other therapies, coinfections, and co-morbidities.

Abstract
INTRODUCTION Antiretroviral therapy (ART) is the most significant advance in the medical management of HIV-1 infection. Given the fact that HIV cannot be eradicated from the body, ART has to be indefinitely maintained. New approaches need to be defined for monitoring HIV-infected individuals (PLWHIV), including clinical, virologic, immunological parameters and also ways to collect individual points of view and quality of life. AREAS COVERED We discuss which tests may be used to improve the management of PLWHIV and respond to a comprehensive health demand. EXPERT OPINION Viral load and CD4 counts are well-validated outcome measures and we still need them, but they do not completely depict the health status of PLWHIV. We need to better understand and to apply to clinical practice what happens in sanctuaries, what is the role of HIV DNA, what is the meaning of low-level viremia. Most of these questions do not yet have a definitive response. Further, we need to understand how to modify these variables in order to improve outcomes.Similar points may be raised for immunological measures and for tests exploring the tolerability of drugs. The goal must be the evolution from a viro/immunologic-based to a comprehensive quality-of-health-based evaluation of PLWHIV.
