Abstract

The aim of the present study was to compare the efficacy and durability of treatment switch to two-drug (2DR) vs. three-drug (3DR) integrase inhibitor (InSTI)-based regimens in a real-life setting.Within the ODOACRE cohort, we selected adult patients with HIV RNA 50 copies/mL switching to an InSTI-based 2DR or 3DR. Survival analyses were performed to estimate the probability of virological failure (VF, defined as one HIV RNA 1000 copies/mL or two consecutive HIV RNA 50 copies/mL) and treatment discontinuation (TD, defined as any modification, intensification or interruption of the regimen), and to evaluate their predictors.Overall, 1666 patients were included, of whom 1334 (80%) were treated with a 3DR (19.9%, 25.0% and 55.1% elvitegravir-, raltegravir- and dolutegravir-based, respectively) and 332 (20%) with a 2DR (79.2% dolutegravir + lamivudine and 20.8% dolutegravir + rilpivirine). Over a median (interquartile range) follow-up of 100 (52-150) weeks, 52 (3.1%) patients experienced VF with an incidence of 1.5/100 person-year of follow-up (PYFU). The estimated 96-week probability of VF was similar for the 2DR and 3DR groups (2.3% vs. 2.8%, P = 0.53), but it was higher for elvitegravir (4.9%) and raltegravir (5.0%) than for dolutegravir (1.5%) (P = 0.04). Four hundred (24%) patients discontinued their InSTI-based regimen, with an incidence of 11.3/100 PYFU. At 96 weeks, 3DRs showed a higher probability of TD for any reason (20.6% vs. 11.2%, P 0.001) and TD for toxicity (9.0% vs. 6.6%, P = 0.02) when compared with 2DRs. A higher risk of TD for central nervous system toxicity was observed for dolutegravir than for elvitegravir and raltegravir (4.0% vs. 2.5% vs. 0.6%, P = 0.005).In virologically suppressed HIV-infected patients, 2DRs showed an efficacy similar to 3DRs but with better tolerability.

Abstract

Background: Combination ART (cART)-related toxicities and costs have prompted the need for treatment simplification. The ATLAS-M trial explored 48 week non-inferior efficacy of simplification to atazanavir/ritonavir + lamivudine versus maintaining three-drug atazanavir/ritonavir-based cART in virologically suppressed patients. Methods: We performed an open-label, multicentre, randomized, non-inferiority study, enrolling HIV-infected adults on atazanavir/ritonavir+two NRTIs, with stable HIV-RNA 200 cells/mm3. Main exclusion criteria were hepatitis B virus coinfection, past virological failure on or resistance to study drugs, recent AIDS and pregnancy. Patients were randomly assigned 1:1 to either switch to 300mg of atazanavir/ 100mg of ritonavir once daily and 300mg of lamivudine once daily (atazanavir/ritonavir+lamivudine arm) or to continue the previous regimen (atazanavir/ritonavir+two NRTIs arm). The primary study outcome was the maintenance of HIV-RNA

Abstract

Background: Immunological non-response (INR) despite virological suppression is associated with AIDS-defining events/death (ADE). Little is known about its association with serious non-AIDS-defining events (nADE). Methods Patients highly-active antiretroviral therapy (HAART) with 50. Results: 1221 patients were observed for a median of 3 (IQR: 1.3-6.1) years. Pre-HAART CD4+were 77/μl (IQR: 28-142) and 56% of patients had experienced an ADE. After 1 year, CD4+ increased to 286 (IQR: 197-387), but 26.1% of patients were INR. Thereafter, 86 nADE (30.2% malignancies, 27.9%infectious, 17.4%renal, 17.4Êrdiovascular, 7% hepatic) were observed, accounting for an incidence of 1.83 events (95%CI: 1.73-2.61) per 100 PYFU. After adjusting for measurable confounders, INR had a significantly greater risk of nADE (HR 1.65; 95%CI: 1.06-2.56). Older age (per year, HR 1.03; 95%CI: 1.01-1.05), hepatitis C co-infection (HR 2.09; 95%CI: 1.19-3.7), a history of previous nADE (HR 2.16; 95% CI: 1.06-4.4) and the occurrence of ADE during the follow-up (HR 2.2; 95%CI: 1.15-4.21) were other independent predictors of newly diagnosed nADE. Conclusions: Patients failing to restore CD4+ to >200 cells/μl run a greater risk of serious nADE, which is intertwined or predicted by AIDS progression. Improved management of this fragile population and innovative therapy able to induce immune-reconstitution are urgently needed. Also, our results strengthen the importance of earlier diagnosis and HAART introduction.

Abstract

A large observational study found an association between the use of the nucleoside reverse transcriptase inhibitor abacavir and an increase of cardiovascular risk in HIV-1–infected patients.1–3 Since then, different studies have reported controversial results: some cohort studies seemed to confirm the observation,4,5 whereas other more recent analyses and a meta-analysis seem to6–9 contradict this hypothesis. Currently, the major treatment guidelines warrant caution in the prescription of this drug in patients already showing a high cardiovascular risk based on traditional parameters.Nonetheless, a biological mechanism explaining the reasons for this finding has never been elucidated. Despite an initial observation of higher levels of inflammatory markers in a cross-sectional analysis of samples from 2 observational cohorts,4 subsequent longitudinal studies failed to detect significant associations between the use of abacavir and changes in the levels of cardiovascular risk biomarkers.

Objectives: We studied survival and associated risk factors in an Italian nationwide cohort of HIV-infected individuals after an AIDS-defining cancer (ADC) or non-AIDS-defining cancer (NADC) diagnosis in the modern cART era. Methods: Multi-center, retrospective, observational study of HIV patients included in the MASTER Italian Cohort with a cancer diagnosis from January 1998 to September 2012. Malignancies were divided into ADC or NADC on the basis of the Centre for Disease Control-1993 classification. Recurrence of cancer and metastases were excluded. Survivals were estimated according to the Kaplan-Meier method and compared according to the log-rank test. Statistically significant variables at univariate analysis were entered in a multivariate Cox regression model. Results: Eight hundred and sixty-six cancer diagnoses were recorded among 13,388 subjects in the MASTER Database after 1998: 435 (51%) were ADCs and 431 (49%) were NADCs. Survival was more favorable after an ADC diagnosis than a NADC diagnosis (10-year survival: 62.7%±2.9% vs. 46%±4.2%; p = 0.017). Non-Hodgkin lymphoma had lower survival rates than patients with Kaposi sarcoma or cervical cancer (10-year survival: 48.2%±4.3% vs. 72.8%±4.0% vs. 78.5%±9.9%; p

Abstract

Background: Neuropsychiatric symptoms (NPs) have been reported with dolutegravir use. We hypothesized that increasing dolutegravir trough concentrations (Ctrough) and/or polymorphism in the SLC22A2 gene, encoding the organic cation transporter-2 (OCT2), which is involved in monoamine clearance in the CNS and is inhibited by dolutegravir, might be associated with NPs.Methods: A cross-sectional cohort of HIV-positive patients treated with a dolutegravir-containing regimen underwent determination of allelic discrimination for SLC22A2 808 C → A polymorphism and dolutegravir Ctrough. The Symptom Checklist-90-R [investigating 10 psychiatric dimensions and reporting a general severity index (GSI)], a self-reported questionnaire and the Mini-International Neuropsychiatric Interview were offered to investigate current NPs. The effects of dolutegravir Ctrough and the SLC22A2 gene variant on NPs were explored by multivariable logistic regression.Results: A cohort of 203 patients was analysed: 71.4% were male, with median age 51 years and 11 years of ART exposure. Median time on dolutegravir was 18 months. Dolutegravir was associated with different antiretroviral combinations (mainly lamivudine, 38.9%, and abacavir/lamivudine, 35.5%). SLC22A2 CA genotype was independently associated with an abnormal GSI [adjusted OR (aOR) 2.43; P = 0.072], anxiety (aOR 2.61; P = 0.044), hostility (aOR 3.76; P = 0.012) and with moderate to severe headache (aOR 5.55; P = 0.037), and dolutegravir Ctrough was associated with hostility (fourth versus first quartile aOR 6.70; P = 0.007) and psychoticism (fourth versus first quartile aOR 19.01; P = 0.008). Other NPs were not associated with SLC22A2 polymorphism or dolutegravir Ctrough.Conclusions: A variant of the OCT2-encoding gene, in addition to or in synergy with higher dolutegravir Ctrough, is associated with a set of NPs observed during dolutegravir therapy.

Abstract

Objectives: The aim was to evaluate the evolution of transmitted HIV‐1 drug resistance (TDR) prevalence in antiretroviral therapy (ART)‐naïve patients from 2006 to 2016. Methods: HIV‐1 sequences were retrieved from the Antiviral Response Cohort Analysis (ARCA) database and TDR was defined as detection of at least one mutation from the World Health Organization (WHO) surveillance list. Results: We included protease/reverse transcriptase sequences from 3573 patients; 455 had also integrase sequences. Overall, 68.1% of the patients were Italian, the median CD4 count was 348 cells/μL [interquartile range (IQR) 169–521 cells/μL], and the median viral load was 4.7 log10 HIV‐1 RNA copies/mL (IQR 4.1–5.3 log10 copies/mL). TDR was detected in 10.3% of patients: 6% carried mutations to nucleos(t)ide reverse transcriptase inhibitors (NRTIs), 4.4% to nonnucleos(t)ide reverse transcriptase inhibitors (NNRTIs), 2.3% to protease inhibitors (PIs), 0.2% to integrase strand transfer inhibitors (INSTIs) and 2.1% to at least two drug classes. TDR declined from 14.5% in 2006 to 7.3% in 2016 (P = 0.003): TDR to NRTIs from 9.9 to 2.9% (P = 0.003) and TDR to NNRTIs from 5.1 to 3.7% (P = 0.028); PI TDR remained stable. The proportion carrying subtype B virus declined from 76.5 to 50% (P < 0.001). The prevalence of TDR was higher in subtype B vs. non‐B (12.6 vs. 4.9%, respectively; P < 0.001) and declined significantly in subtype B (from 17.1 to 8.8%; P = 0.04) but not in non‐B subtypes (from 6.1 to 5.8%; P = 0.44). Adjusting for country of origin, predictors of TDR were subtype B [adjusted odds ratio (AOR) for subtype B vs. non‐B 2.91; 95% confidence interval (CI) 1.93–4.39; P < 0.001], lower viral load (per log10 higher: AOR 0.86; 95% CI 0.75–0.99; P = 0.03), site in northern Italy (AOR for southern Italy/island vs. northern Italy, 0.61; 95% CI 0.40–0.91; P = 0.01), and earlier calendar year (per 1 year more recent: AOR 0.95; 95% CI 0.91–0.99; P = 0.02). Conclusions: The prevalence of HIV‐1 TDR has declined during the last 10 years in Italy. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: This study aimed at defining protease (PR) resistance mutations associated with darunavir (DRV) failure and PR resistance evolution at DRV failure in a large database of treatment-experienced human immunodeficiency virus (HIV) patients. Results: Overall, 1,104 patients were included: 118 (10.7%) failed at a median observation time of 16 months. The mean number of PR mutations at baseline was 2.7, but it was higher in patients who subsequently failed DRV. In addition, the number of PR mutations increased at failure. The increase in the mean number of mutations was completely related to mutations considered to be associated with DRV resistance following the indications of the main DRV clinical trials. Discussion The higher statistical difference at baseline between failing versus non-failing patients was observed for the V32I and I84V mutations. At DRV failure, the major increase was still observed for V32I; I54L, V11I, T74P and I50V also increased. Despite the increment in the mean number of mutations per patient between baseline and failure, in 21 patients (17.8%) at baseline and 36 (30.5%) at failure, no PR mutation was detected. Conclusion: The HIV-DB interpretation algorithm identified few patients with full DRV resistance at baseline and few patients developed full resistance at DRV failure, indicating that complete resistance to DRV is uncommon. © Springer-Verlag 2011.

Abstract

Randomized trials and observational cohorts reported higher rates of virological suppression after highly active antiretroviral therapy (HAART) including efavirenz (EFV), compared with boosted protease inhibitors (PIs). Correlations with immunological and clinical outcomes are unclear. Patients of the Italian MASTER cohort who started HAART from 2000 to 2010 were selected. Outstanding outcome (composite outcome for success (COS)) was introduced. We evaluated predictors of COS (no AIDS plus CD4+ count >500/mm3 plus HIV-RNA

Abstract

Objectives: To examine the impact of transmitted drug resistance (TDR) on response to first-line regimens with integrase strand transfer inhibitors (INSTIs) or boosted protease inhibitors (bPIs).Methods: From an Italian observational database (ARCA) we selected HIV-1-infected drug-naive patients starting two NRTIs and either an INSTI or a bPI, with an available pre-ART resistance genotype. The endpoint was virological failure (VF; plasma HIV-1 RNA >200 copies/mL after week 24). WHO surveillance drug resistance mutations and the Stanford algorithm were used to classify patients into three resistance categories: no TDR (A), TDR but fully-active ART prescribed (B), TDR and at least low-level resistance to one or more prescribed drug (C).Results: We included 1365 patients with a median follow-up of 96 weeks (IQR 54-110): 1205 (88.3%) starting bPI and 160 (11.7%) INSTI. Prevalence of TDR was 6.1%, 12.5%, 2.6% and 0% for NRTI, NNRTI, bPI and INSTI, respectively. Cumulative Kaplan-Meier estimates for VF at 48 weeks were 11% (95% CI 10.1%-11.9%) for the bPI group and 7.7% (95% CI 5.4%-10%) for the INSTI group. In the INSTI group, cumulative estimates for VF at 48 weeks were 6% (95% CI 4%-8%) in resistance category A, 5% (95% CI 1%-10%) in B and 50% (95% CI 30%-70%) in C (P < 0.001). Resistance category C [versus A, adjusted hazard ratio (aHR) 12.6, 95% CI 3.2-49.8, P < 0.001] and nadir CD4 (+100 cells/mm3, aHR 0.6, 95% CI 0.4-0.9, P = 0.03) predicted VF. In the bPI group, VF rates were not influenced by baseline resistance.Conclusions: Our data support the need for NRTI resistance genotyping in patients starting an INSTI-based first-line ART.

Abstract

Background: Under HAART, 7-39% of HIV-infected patients (pts) fail to exhibit a recovery in CD4 cells despite full suppression of viral replication. In MOTIVATE trials, MVC was superior to OBT in increasing CD4 cells in ARV-experienced pts. This study evaluated the clinical efficacy of MVC in terms of CD4 cells recovery, viral replication and tolerability in INR pts. Methods: Randomised, multicentre, proof of concept study enrolling 100 pts divided into 2 arms: A HAART+MVC, B HAART. Planned F-U is 1 year. Ultrasensitive HIV-RNA was quantified via Amplicor HIV-1 Monitor Kit v1.5, followed by RT-PCR for quantifying 1-50 cp/mL. Naive CDRA+62L+, memory CD45RA-, activated HLADR+ CD38+, proliferating Ki67+ were measured by flow cytometry. T-test was used for intra and inter-group comparisons. ANCOVA was used to adjust the baseline values. Results: 100 pts have been randomized (50 pts/arm). 59 pts reached week 12: 30 in arm A and 29 in arm B. 2 HIV-unrelated clinical events were registered in arm B and 2 in arm A (not known the correlation with MVC administration) as well as 9 drop-outs at baseline (withdrawal of the informed consent). No grade 3-4 lab toxicity were reported. At baseline, CD4/CD8 and immune-phenotype was comparable in arm A and B. At week 12, no significant changes in mean CD4 recovery were seen between pts in arm A and B (+41,2 vs -11,6/?l; p=.12). A statistically significant change was observed in mean CD8+ count between pts in arm A and B (+99,3 vs -126,1/?l, p=.025) At baseline and week 12 an immunological study performed by flow cytometry was carried out in 24 out of 61 pts (13 in arm A, 11 in arm B): at week 12, while B pts experienced a progressive contraction of naive CD4 (81 to 67%, p=.02) and CD8 (81 to 77%, p=.04) with a parallel rise in memory CD4 (16 to 30%, p=.02) and CD8 (13 to 17%, p=.06), no significant loss of naive CD4 (70 to 57%, p=.18) and CD8 (69 to 66%, p=.42) was displayed by A pts with a tendency to higher gain in memory CD4 (24 to 40%, p=.06) and CD8 (11 to 25%, p=.008). By week 12, a similar reduction in activated HLA-DR+CD38+ CD8 and CD4 was shown in B (p=.05) and A pts (p=.03 and p=.02 for CD8 and CD4). No changes were shown in proliferating Ki67+CD4 in A (p=.42) and B pts (p=.47), while a tendency to Ki67+CD8 reduction was shown in A (p=.06) and not in B pts (p=.45). HIV-RNA quantification evidenced a trend to higher median values (BL vs week 12) in B pts: 2 vs 5 cp/mL (p=.37). No changes occurred in arm A. Conclusions: we can consider the use of MVC as intensification strategy that seems to impact T-cell peripheral immune-phenotype after examining the significant change in CD8* cells count and the evidence of not significant CD4 gain in arm A.Our findings of reduced loss of naive T-cells with a parallel robust rise in the memory pool suggest a role of MVC in reducing peripheral antigen-driven T-cell death, possibly preserving new T-cell production. However, further data are needed to confirm our results.

Abstract

Genotypic assays are widely used tools for determining human immunodeficiency virus type 1 (HIV-1) drug resistance and for guiding treatment changes in patients failing antiretroviral therapy. Several systems have been developed to interpret the complex influence of key amino acid substitutions of the enzymes targeted by therapy on the phenotypic susceptibility or clinical response to available antiretroviral agents. This overview identifies 21 systems giving an interpretation on how amino acid substitutions affect phenotypic drug susceptibility or clinical activity of anti-HIV-1 agents. There was substantial variability in the mechanisms underlying the interpretations, the nature of the systems, their intended use, the source type of their knowledge base, and their update and output. Most of the systems could be accessed for free on the internet, functioned as rule-based algorithms updated by experts and at least partially based on literature evidence, and offered an automated report through a software. Nevertheless, the rule base was not always clarified. An update of the rules and the clinical validation of the systems are presented to help in the critical evaluation of their possible use. Importantly, only 8 systems were intended for clinical use and 5 of these had at least partially undergone clinical validation. [ABSTRACT FROM AUTHOR]
