Abstract Background Switching from boosted PIs to dolutegravir in people living with HIV (PLWH) with high cardiovascular risk improved plasma lipids at 48 weeks in the NEAT022 trial. Whether this strategy may have an impact on cardiovascular biomarkers is unknown. Methods We assessed 48 week changes in biomarkers associated with inflammation, endothelial dysfunction, monocyte immune activation, oxidation, insulin resistance, hypercoagulability, heart failure, myocardial injury, and glomerular and tubular kidney injury. Results Of 415 PLWH randomized in the NEAT022 study, 313 (75.4%) remained on allocated therapy and had paired samples available. Soluble CD14 (–11%, P < 0.001) and adiponectin (–11%, P < 0.001) significantly declined and high-sensitive C-reactive protein (–13%, P = 0.069) and oxidized LDL (–13%, P = 0.084) tended to decrease with dolutegravir. Switching to dolutegravir remained significantly associated with soluble CD14 and adiponectin reductions after adjustment for baseline variables. There were inverse correlations between soluble CD14 and CD4 count changes (P = 0.05), and between adiponectin and BMI changes (P < 0.001). Conclusions Switching from boosted PIs to dolutegravir in PLWH with high cardiovascular risk led to soluble CD14 and adiponectin reductions at 48 weeks. While decreasing soluble CD14 may entail favourable health effects in PLWH, adiponectin reduction may reflect less insulin sensitivity associated with weight gain.
Transmission of HIV-1 and drug resistance continue to occur at a considerable level in Italy, influenced mainly by changes in modality of infection. However, the long period of infectivity makes difficult the interpretation of epidemiological networks, based on epidemiological data only. We studied 510 naive HIV-1-infected individuals, of whom 400 (78.4%) were newly diagnosed patients with an unknown duration of infection (NDs), with the aim of identifying sexual epidemiological networks and transmitted drug resistance (TDR) over a 7-year period. Clusters were identified by Bayesian methods for 412 patients with B subtype; 145 individuals (35.2%) clustered in 34 distinct clades. Within epidemiological networks males were 93.1% (n=135); the same proportion of patients has been infected by the sexual route; 62.1% (n=90) were men having sex with men (MSM) of whom 67.8% (n=61) were NDs. Among heterosexuals (n=44), males were predominant (79.5%, n=35) and 77.3% (n=34) were NDs. TDR in clusters was 11.7 % (n=17), of whom 76.5% (n=13) was found in MSM. TDR was predominantly associated with NRTI resistance in individuals with chronic infection (n=11). A high prevalence of epidemiological networks has been found in the metropolitan area of Milan, indicating a high frequency of transmission events. The cluster analysis of networks suggested that the source of new infections was mainly represented by males and MSM who have long lasting HIV-1 infection. Notably, the prevalence of resistance-conferring mutations was higher in chronically infected patients, carrying mainly resistance to thymidine analogs, the backbone of first antiretroviral (ARV) generation. Intervention strategies of public health are needed to limit HIV-1 transmission and the associated TDR.
Abstract Background In the NEAT022 trial, switching from boosted PIs (PI/r) to dolutegravir in people with HIV (PWH) with high cardiovascular risk decreased plasma lipids, soluble CD14 and adiponectin, and showed consistent favourable, although non-significant, effects on carotid intima-media thickness (CIMT) progression at 48 weeks. We hereby communicate planned final 96 week results on biomarker changes and CIMT progression. Methods PWH on a PI/r-based triple therapy regimen were randomly assigned (1:1) to switch the PI/r component to dolutegravir either immediately (DTG-I group) or after 48 weeks (DTG-D group) and were followed up to 96 weeks. We assessed changes in biomarkers associated with inflammation, endothelial dysfunction, monocyte immune activation, oxidation, insulin resistance, hypercoagulability, heart failure, myocardial injury and glomerular and tubular kidney injury, and right and left CIMT progression at 48 and 96 weeks. Results Of 415 PWH randomized, 287 (69%) and 143 (34%) contributed to the biomarker and CIMT substudies respectively. There were significant 96 week changes in biomarkers associated with inflammation, immune activation, oxidation, insulin resistance and myocardial injury. Most changes were favourable, except for adiponectin reduction, which may suggest higher insulin resistance. We were unable to detect significant changes in the progression of CIMT between arms or within arms at 96 weeks. Discussion After 96 weeks, switching from PI/r to dolutegravir in PWH with high cardiovascular risk led to significant changes in several biomarkers associated with cardiovascular disease. Although most changes were favourable, adiponectin reduction was not. There were non-significant changes in CIMT progression.
High rates of psychological and psychiatric disorders have been documented in both perinatally (PHIV) and behaviorally (BHIV) acquired HIV adolescents, that can considerably influence their quality of life (QoL) and mental health.Few data are available among HIV-infected adolescents and even fewer among infected women, although they should deserve special attention due to the high incidence rate identified in recent years and the discrimination they suffer.We implemented a crosssectional study among 22 young women, aged between 15 and 35 years, with HIV infection, evaluating their quality of life (WHOQOL-HIV-BREF), cognitive performance (Wechsler Adult Intelligence Scale), and personality profile (Rorschach Test), focusing on specific subgroups, in order to implement more effective models of HIV care and targeted interventions focusing on subgroups and their particular needs.Most subjects reported a good (45%), or a very good (36%) quality of life, and a very good satisfaction with their health status (68%), however 50% of our cohort reported stigma-related experiences, with no differences between BHIV and PHIV, (p=0.26).Assessment of the Intelligence Quotient showed no difference between the two groups: 86.5 (IQR 79-95) for PHIV versus 92 (IQR 83-97) for BHIV, (p=0.45).On the other hand, Rorschach Test showed for BHIV higher trends of emotional constriction and higher levels of anxiety, (p=0.047), an infantile organization of personality, (p=0.014), a dysfunctional perception, (p=0.07), a poorer control over action, (p=0.021), and a less controlled emotional discharge, (p=0.035).PHIV reported higher fear of disclosing their status to partners, with consequent lower satisfaction in sexual life, (p=0.046).Finally, both groups reported high rates of Depression index itself, with a higher trend in BHIV, (BHIV 75%, PHIV 43%, p=0.15).Our study offers some initial basis, indicating that these patients may truly benefit from integrated mental health evaluations and interventions focused on psychological tuning and on specific subgroups needs.
