Hepatitis C virus-related factors associated WITH cognitive performance in HIV-HCV-coinfected patients. J Neurovirol 2019; 25:866-873. [PMID: 31281946 DOI: 10.1007/s13365-019-00780-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 06/10/2019] [Accepted: 06/19/2019] [Indexed: 02/07/2023]
Abstract
The contribution of HCV-related variables to cognitive impairment in HIV-HCV-coinfected patients has been poorly investigated. We selected HIV-HCV-coinfected patients undergoing cognitive examination (exploring memory, language, speed of mental processing and fine motor function) at three clinical centres. Cognitive performance was evaluated using Z-transformed scores. Logistic regression analysis was used to investigate variables associated to cognitive impairment (defined as a composite Z-score ≤ - 1). Overall, 146 HIV-HCV-coinfected patients were enrolled. Median HCV-RNA was 6.2logU/mL. HCV genotype 1a/b was the most represented (53.4%). Liver fibrosis was mild (Fib4 ≤ 1.45) in the majority of patients (44.5%). Global cognitive impairment was diagnosed in 35 (24%) subjects. Exploring each domain, a higher proportion of impairment was observed for memory (37%) followed by speed of mental processing (32.2%), fine motor functioning (24%) and language (18.5%). Among HCV-related variables, the duration of HCV infection was independently associated with global cognitive impairment (aOR 1.13 per +1 year, p = 0.016) and abnormal speed of mental processing (aOR 1.16 per +1 year, p = 0.001), while higher HCV-RNA was independently associated to fine motor functioning impairment (aOR 1.98 per +1log, p = 0.037). HCV genotype, fibrosis stage, transaminases or bilirubin levels were not related to cognitive performance. Of note, integrase inhibitor (InSTI) use was independently associated to a pathological performance in fine motor functioning (aOR 3.34, p = 0.035) and memory (aOR 3.70, p = 0.014). In conclusion, the duration of HCV infection and HCV-RNA load showed an association with cognitive impairment, suggesting a role of hepatitis-related factors in the development of cognitive disorders in HIV-HCV-coinfected patients. The association between InSTI use and altered cognitive performance should prompt investigations about potential neurotoxicity of these drugs.

Abstract
To assess the impact of genotypic susceptibility score (GSS) on combined antiretroviral therapy (cART) outcomes during primary HIV infection (PHI) we retrospectively enrolled patients with PHI diagnosed between 2008 and 2015 at 9/24 Italian Network ACuTe HIV InfectiON centers. One hundred-seventy-six patients were enrolled. Of these, 55 (32.9%) patients started with more than three drugs and 11 (7.2%) started with a GSS < 3. Regimen's GSS (per 1 point increase) (adjusted odds ratio [aOR], 4.82; 95% confidence interval [CI], 1.62-14.28; P = .005) and baseline HIV-RNA (per 1 log10 increase) (aOR, 2.02; 95% CI, 1.09-3.73; P = .025) resulted associated with early cART initiation. In conclusion, regimen's GSS resulted to be associated to the time to cART initiation during PHI.

Abstract
Hepatitis A is a self-limiting infection representing the most common cause of viral hepatitis worldwide. Despite being a low incidence region, in the European Union, an increasing number of cases have been reported since summer 2016, resulting in a large outbreak in 2017, involving mainly men who have sex with men (MSM). Some reports described a different clinical course of hepatitis A virus in patients infected by human immunodeficiency virus (HIV) or MSM. We consecutively collected all the hospitalized cases of hepatitis A referred to two tertiary centres in Northern Italy in 2017 and retrospectively analysed the electronic records of the 2009-2016 period (pre-2017). We evaluated demographics data, risk factors, comorbidities and laboratory results to see whether MSM status or HIV infection influenced the disease. Overall, 117 cases were identified in 2017:107 (91%) were male, 78 reported themselves as MSM (66%) and 17 (14.5%) were infected by HIV. For the pre-2017 period, 48 cases were reported: 29 (60%) were male and 3 (6.2%) were infected by HIV. After stratification for HIV infection, MSM status and occurrence period, no differences were found in aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase; bilirubin, alkaline phosphatase and bilirubin values, hospitalization length, HIV viral load and CD4 + cells count. HIV-positive patients presented a higher number of patients with INR > 1.5 at admission. MSM status and HIV infection did not affect neither the clinical course nor the severity of hepatitis A.

Abstract
Objectives The AtLaS-M randomized trial showed that in patients with HIV-1 RNA <50 copies/mL on atazanavir/ritonavir + two NRTIs, switching to a dual therapy with atazanavir/ritonavir+lamivudine had superior efficacy as compared with continuing the previous triple therapy. This substudy was designed to evaluate at 48 weeks the impact of the dual therapy versus the three-drug atazanavir/ritonavir-based therapy on the HIV-1 cellular reservoir as reflected by the quantification of blood-associated HIV-1 DNA levels. Methods In a representative subset of 201 of 266 randomized patients (104 in the dual-therapy arm and 97 in the triple-therapy arm) total HIV-1 DNA levels in whole blood at baseline and after 48 weeks and factors associated with the HIV-1 DNA levels were evaluated. Results The mean baseline HIV-1 DNA levels (2.47 log 10 copies/10 6 leucocytes) were comparable between arms. A significant mean decrease between baseline and week 48 was observed: -0.069 log 10 copies/10 6 leucocytes in the dual-therapy arm ( P = 0.046) and -0.078 in the triple-therapy arm ( P = 0.011); the mean difference between arms was -0.009 ( P = 0.842). Nadir CD4 count was inversely correlated with baseline HIV-1 DNA ( P = 0.009); longer duration of ART and lower nadir CD4 correlated with a less prominent HIV-1 DNA decrease (both P < 0.005). Higher baseline HIV-1 DNA was associated with residual viraemia at week 48 ( P = 0.031). Conclusions When compared with continuing three-drug therapy, atazanavir/ritonavir+lamivudine dual therapy resulted in a similar decline in HIV-1 DNA levels in patients with sustained virological suppression. These data support the safety of this simplified treatment strategy in terms of its effect on the cellular HIV-1 reservoir.

Abstract
Background Inflammasome-mediated activation of caspase-1 regulates inflammatory responses and pyroptosis. We analyzed possible associations between inflammasome-related genes and immune reconstitution in HIV-infected antiretroviral therapy (ART)-treated patients. Methods Cross-sectional, case–control study. HIV-infected patients on ART for ≥24 months with HIV-RNA<50 cp/mL for ≥12 months were enrolled and defined as immunological responders (IR) or non-responders (INR) if CD4 count was ≥500 or ≤350 cells/μL, respectively. Expression of inflammasome genes, caspases 1, 3, 4, 5 and γ-interferon-inducible protein 16 (IFI16) was measured in unstimulated and LPS- or aldrithiol-2-treated HIV-1BaL virions-stimulated peripheral blood mononuclear cells. Microbial translocation markers were evaluated. Results Thirty-nine patients (22 IRs; 17 INRs) were enrolled. LPS-stimulated inflammasome genes were significantly upregulated in INRs. Whereas HIV-1BaL stimulation induced (NOD)-like receptor (NLR) family pyrin domain containing 3 (NLRP3) expression in both IRs and INRs, NLRP3 and IL-18 expression was significantly increased in INRs compared to IRs. Significant higher caspase-1 expression was seen as well, whereas caspase 3, 4, and 5 expression was similar in both groups. No differences in microbial translocation markers (LPS and soluble CD14) were detected in the two groups. Conclusion Upregulation of NLRP3 and caspase-1 is observed in INR patients. This could play a role in persistent immune activation that characterize INRs. Caspase-1 upregulation could induce CD4 T-cell loss via pyroptosis, contributing to unsatisfactory CD4 T-cells recovery.

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 <50 copies/mL and CD4 + >200 cells/mm 3 . 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 300 mg of atazanavir/100 mg of ritonavir once daily and 300 mg 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 <50 copies/mL at week 48 of the ITT-exposed (ITT-e) analysis with switch = failure. The non-inferiority margin was 12%. This study is registered at ClinicalTrials.gov, number NCT01599364. Results Between July 2011 and June 2014, 266 patients were randomized (133 to each arm). After 48 weeks, the primary study outcome was met by 119 of 133 patients (89.5%) in the atazanavir/ritonavir + lamivudine arm and 106 of 133 patients (79.7%) in the atazanavir/ritonavir + two NRTIs arm [difference atazanavir/ritonavir + lamivudine versus atazanavir/ritonavir + two NRTIs arm: +9.8% (95% CI + 1.2 to + 18.4)], demonstrating non-inferiority and superior efficacy of the atazanavir/ritonavir + lamivudine arm. Virological failure occurred in two (1.5%) patients in the atazanavir/ritonavir + lamivudine arm and six (4.5%) patients in the atazanavir/ritonavir + two NRTIs arm, without resistance selection. A similar proportion of adverse events occurred in both arms. Conclusions Treatment simplification to atazanavir/ritonavir + lamivudine showed non-inferior efficacy (superiority on post-hoc analysis) and a comparable safety profile over continuing atazanavir/ritonavir + two NRTIs in virologically suppressed patients.

Abstract
BACKGROUND Few data are available about efficacy and durability of simplification from multi-tablet antiretroviral regimens to co-formulated efavirenz (EFV)/emtricitabine (FTC)/tenofovir (TDF) versus rilpivirine (RPV)/FTC/TDF in virologically suppressed HIV-1-infected patients. METHODS We retrospectively analysed HIV-infected patients with HIV RNA <50 copies/ml switching to co-formulated EFV/FTC/TDF or RPV/FTC/TDF at five Italian centres. Patients were followed from time of switch until regimen discontinuation or a maximum of 3-years follow-up. Time to treatment discontinuation (TD) and virological failure (VF; defined as two consecutive HIV RNA >50 copies/ml or a single determination >1,000 copies/ml) and their predictors were investigated. RESULTS 1,560 patients were reviewed of which 1,097 (70%) switched to EFV/FTC/TDF and 463 (30%) to RPV/FTC/TDF. During follow-up, VF and TD occurred in 44 (4%) and 242 (22%) patients in EFV/FTC/TDF and in 29 (6%) and 50 (11%) patients in RPV/FTC/TDF, respectively. The 3-year estimated probability of remaining free from VF was 96.2% with EFV/FTC/TDF versus 92.7% with RPV/FTC/TDF (P=0.003). At multivariate analysis, regimen type (EFV/FTC/TDF versus RPV/FTC/TDF aHR 0.24; P=0.004) and time of virological suppression (aHR 0.85; P=0.048) were the only independent predictors of VF. The estimated 3-year probability of remaining free from TD was 77.4% with EFV/FTC/TDF versus 88.4% with RPV/FTC/TDF (P=0.001). Predictors of TD were female sex, switching from PI-based regimens, older age, shorter time of virological suppression and regimen type (EFV/FTC/TDF versus RPV/FTC/TDF aHR 2.48; P<0.001). RPV/FTC/TDF showed a safer lipid profile and a greater increase in creatinine. CONCLUSIONS Both regimens showed good safety and efficacy in this real-life setting, although switch to RPV/FTC/TDF seemed better tolerated while EFV/FTC/TDF was associated with a lower probability of VF.

Abstract
Background This analysis aimed at evaluating the impact of a therapeutic strategy of treatment simplification of atazanavir (ATV)+ ritonavir (r) + lamivudine (3TC) in virologically suppressed patients receiving ATV+r+2 nucleoside reverse transcriptase inhibitors (NRTIs) on the budget of the Italian National Health Service (NHS). Methods A budget impact model with a 5-year time horizon was developed based on the clinical data of Atlas-M trial at 48 weeks (in terms of percentage of patients experiencing virologic failure and adverse events), from the Italian NHS perspective. A scenario in which the simplification strategy was not considered was compared with three scenarios in which, among a target population of 1,892 patients, different simplification strategies were taken into consideration in terms of percentage of patients simplified on a yearly basis among those eligible for simplification. The costs considered were direct medical costs related to antiretroviral drugs, adverse events management, and monitoring activities. Results The percentage of patients of the target population receiving ATV+r+3TC varies among the scenarios and is between 18.7% and 46.9% in year 1, increasing up to 56.3% and 84.4% in year 5. The antiretroviral treatment simplification strategy considered would lead to lower costs for the Italian NHS in a 5-year time horizon between −28.7 million € and −16.0 million €, with a reduction of costs between −22.1% (−3.6 million €) and −8.8% (−1.4 million €) in year 1 and up to −39.9% (−6.9 million €) and −26.6% (−4.6 million €) in year 5. Conclusion The therapy simplification for patients receiving ATV+r+2 NRTIs to ATV+r+3TC at a national level would lead to a reduction of direct medical costs over a 5-year period for the Italian NHS.

Abstract
Tenofovir could have a direct lipid-lowering effect. The aim of our retrospective study was to investigate changes in cardiovascular risk after switching from a tenofovir-sparing to a tenofovir-containing backbone. Lipid parameters and cardiovascular risk [calculated using 10-years Framingham Risk Score (FRS) and 5-years DAD Risk Score (DRS)] were analysed at baseline and after three months. 273 patients were enrolled. After switching, significant decreases in total cholesterol (TC) (-8.2mg/dl, p < 0.001), LDL (-8.7mg/dl, p < 0.001) and DRS (mean -0.26%, p < 0.001) were observed, while a reduction in FRS was only observed in patients with pre-switch high TC or medium-high (>10%) FRS. Pre-switch factors associated with DRS reduction were higher TC, abacavir, new generation protease inhibitors, while zidovudine predicted an increase of DRS. Our results suggest that the improvement of lipid parameters observed after switching to a tenofovir-containing backbone could lead to a significant reduction in predicted cardiovascular risk, which became more evident in subjects with higher cardiovascular risk.

Abstract
The 13-valent pneumococcal conjugate vaccine (PCV-13) is recommended for HIV-infected people, although its effectiveness in this population remains under evaluation. In this study, we describe the development, optimization, and analytical validation of an ELISA procedure to measure specific antibodies for the pneumococcal polysaccharide serotypes included in PCV13 vaccine, testing sera obtained from HIV-infected outpatients (n = 30) who received the vaccine. The protocol followed the last version of WHO guidelines, based on the new standard 007sp, with the modification of employing Statens Serum Institut (SSI) antigens. We supplied the assay performance validation in terms of sensitivity, reproducibility, precision and accuracy. In addition we detailed optimal antigen-coating concentrations and ELISA conditions common to all 13 serotypes, suitable for laboratories performing these assays in order to standardize the method. Our procedure showed reproducibility and reliability, making it a valid alternative for evaluating the response to pneumococcal serotypes included in PCV13 vaccine.

Abstract
BACKGROUND Aim of the study was to assess predictors of discontinuation/toxicity of boosted PI-based (PI/r) dual therapy (DT). METHODS Observational, retrospective switch study in patients successfully treated with triple drugs regimen. Patients switched to PI/r based DT [darunavir (DRV/r), lopinavir (LPV/r) or atazanavir (ATV/r)] plus a second drug: [raltegravir (RAL), maraviroc (MVC) etravirine (ETR), lamivudine (3TC) or tenofovir (TDF)] between 2009 and 2014 were included. The effect of each drug as well as other clinical and virological cofactors over treatment discontinuation (TD) was assessed using survival analysis. RESULTS Overall, 376 patients were included with mean follow-up of 73 weeks. The most commonly used drugs in DT were DRV/r (63.0 %) and RAL (53.7 %). TD was observed in 77 (20,4 %) patients: 38 (10,1 %) virological failure, 35 (9,3 %) toxicity/intolerance (4 deaths) and 4 (1 %) interruptions for patients decision. At Cox Model, adjusted by demographic and laboratory variables, DRV/r and ATV/r significantly reduced the likelihood of TD and longer treatment was associated with lower risk, while low CD4 count at baseline and number of previous regimens with a higher risk. Moreover, RAL and 3TC use were significantly associated with lower TD by toxicity. CONCLUSIONS In our clinical practice experience, switching virologically suppressed patients to PI/r based DT showed adequate safety and efficacy, so that it may be used in selected patients with specific medical needs.

Abstract
INTRODUCTION Patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) suffer from faster progression of liver fibrosis (LF) and have greater risk of worse clinical outcomes. We evaluated predictors and incidence of these events in a large multicentre cohort. METHODS We selected all HIV-infected patients starting a first-line combination antiretroviral therapy (cART), with detectable HCV-RNA, without exposure to interferon/ribavirin, with ≥2 fibrosis-4 index (FIB-4) classifications before cART. Kaplan-Meier analysis was used to estimate incidence of clinical events (AIDS, non-AIDS related, deaths) and LF progression (via transitions: from FIB-4 class 1 to 2 or 3, from class 2 to class 3, and worsening by 0.5 point). Multivariate Cox regression was used to assess predictors, baseline, or time updated. RESULTS One thousand four hundred thirty-three patients were selected. Overall, 745 clinical events occurred, with an incidence of 7.6% over 9811 person-year of follow-up (PYFU) and a median survival time of 9.36 years. Incidence of LF progression from FIB-4 class 1 to 2 or 3 was 12.4%, and from FIB-4 class 2 to 3 was 7% with a median survival time of 5.67 and 10.35 years, respectively. At multivariate analyses, intravenous drug use and time-updated gamma-glutamyl transferase (γGT) were negative predictors for any outcomes, either clinical or FIB-4 progression. Higher CD4+ T-cell protected from clinical events, and lower HIV-RNA and higher CD4+ T-cell appeared to protect from FIB-4 transitions. Moreover, independently from the viro-immunological status, current FIB-4 class 3 predicted clinical events. Occurrence of AIDS and cardiovascular/kidney events were significant predictors of 0.5 point worsening and transitions of FIB-4, respectively. Prolonged exposure to nucleos(t)ide reverse transcriptase inhibitors (NRTI) was a negative predictor for any outcomes. CONCLUSION Both clinical and LF progression in HIV/HCV-coinfected patients depend strongly on immune status. Intravenous drug users and patients with high γGT (a possible proxy for alcohol abuse) are most-at-risk for both outcomes, as well those who had prolonged exposures to the NRTI class. Therefore, these patients should be prioritized for the access to anti-HCV therapy and a test-and-treat strategy should be implemented for early initiation of cART. Possible benefits of NRTI sparing regimens in HIV/HCV-coinfected patients should be investigated.

Abstract
HIV+ population is getting older because of progress in treatments. Yet, there are concerns that Older HIV+ individuals (OHIV+) may be more vulnerable for developing a "cortical" dementia such as Alzheimer Disease (AD). Our aim was to explore the hypothesis that the cognitive deficit extends to ''cortical'' functions in OHIV+ by comparing serial position effects (SPE) in different groups of participants affected by "cortical" or "subcortical" damage. We enrolled a total of 122 subjects: 22 OHIV+ (≥60 years of age), 31 Younger HIV+ (YHIV+) (<60 years of age), 18 participants with AD, 23 subjects with Parkinson Disease (PD), and 28 healthy subjects. All subjects performed verbal learning tasks (VLT) to explore SPE. Factorial analysis of covariance showed a significant effect of "group" (p < 0.001) and "task" (Primacy vs Recency) (p < 0.001), but no significant group*task (p = 0.257) interaction. Compared with healthy subjects (p = 0.003), AD had the most severe reduction of Primacy, confirming a primary "encoding deficit," while PD confirmed a "frontal pattern." OHIV+ showed a memory profile similar to that of PD with a worsening of the cognitive performance in comparison with YHIV+. In conclusion, we did not confirm the "cortical" hypothesis in OHIV+, at least in terms of learning and memory functions.

Abstract
Objectives Definition of the optimal pneumococcal vaccine strategy in HIV-infected adults is still under evaluation. We aimed to compare immunogenicity and safety of the 13-valent pneumococcal conjugate vaccine (PCV13) versus the 23-valent polysaccharide vaccine (PPSV23) in HIV-infected adults. Methods We performed a pilot, prospective controlled study enrolling HIV-infected pneumococcal vaccine-naïve outpatients, aged 18–65 years with CD4 counts ≥200 cells/μL. Eligible subjects were recruited into two parallel groups: group 1 (n = 50) received two doses of PCV13 eight weeks apart, and group 2 (n = 50) received one dose of PPSV23, as part of their standard of care. Anti-pneumococcal capsular polysaccharide immunoglobulin G concentrations were quantified by ELISA at baseline, 8, 24 and 48 weeks. Clinical and viro-immunological follow-up was performed at the same time points. Unvaccinated, age-matched HIV-negative adults (n = 100) were also enrolled as baseline controls. Results Pre-vaccination specific IgG titers for each pneumococcal antigen did not differ between study groups but they were constantly lower than those from the HIV-negative controls. After immunization, significant increases in IgG titers were observed in both study groups at each time point compared to baseline, but response to serotype 3 was blunted in group 1. Antibody titers for each antigen did not differ between study groups at week 48. Overall, the proportion of subjects achieving seroprotection and seroconversion to all serotypes was comparable between groups. A marked decrease in IgG levels over time was observed with both vaccines. No relevant adverse reactions were reported in either group. Conclusions In this population with favorable immune profile, no relevant differences were observed in immunogenicity between PCV13 and PPSV23. Both vaccines were safe and well tolerated.

Abstract
OBJECTIVE Despite the progress in HIV treatments, mild forms of cognitive impairment still persist. Brief and sensitive screening tools are needed. We evaluated the accuracy of the Montreal Cognitive Assessment (MoCA) compared to the Mini Mental State Examination (MMSE) to detect cognitive impairment in HIV-infected participants. METHOD HIV-infected patients were consecutively enrolled during routine outpatient visits at a single institution. The MoCA, the MMSE, and a comprehensive neuropsychological battery were administered. Patients were considered as affected by cognitive impairment if they showed decreased cognitive function in at least two ability domains based on age and education adjusted Italian normative cut-offs. RESULTS Ninety-three HIV-infected participants (75% males, median age 47, all on antiretroviral therapy; 90% HIV-RNA <50copies/mL, median CD4 644 cells/μL) were enrolled. Thirteen participants (14%) were diagnosed as cognitively compromised via a comprehensive neuropsychological examination. The area under the curve of the adjusted MMSE and MoCA scores to detect cognitive impairment were .51 (95% CI = .31-.72, p = .877) and .70 (95% CI = .53-.86, p = .025), respectively. A MoCA score <22 was able to predict the cognitive impairment with 62% of sensitivity and 76% of specificity. CONCLUSIONS Our findings suggested that the prognostic performance of the MoCA to detect cognitive impairment among mildly impaired HIV-infected participants was only moderate. Further investigations are needed to identify optimal cognitive tests to screen HIV-infected individuals or to explore whether a combination of cognitive tests might represent a viable alternative to a single screening tool.
