Abstract
AIMS This phase I study investigated potential drug-drug interactions of the maturation inhibitor GSK3640254 (GSK'254) with darunavir/ritonavir (DRV/RTV) and/or etravirine (ETR). METHODS In this randomized, open-label, single-sequence, multiple-dose study, healthy participants received GSK'254 200 mg once daily alone or coadministered with DRV/RTV 600/100 mg twice daily (BID; n = 19), ETR 200 mg BID (n = 19) or DRV/RTV 600/100 mg + ETR 200 mg BID (n = 16) under fed conditions. Primary endpoints were steady-state area under the plasma concentration-time curve from time 0 to the end of the dosing interval (AUC0-τ ) and maximum observed concentration (Cmax ). Secondary endpoints included trough concentration (Cτ ), safety and tolerability. Pharmacokinetic parameters were calculated using standard noncompartmental analysis, and geometric least-squares mean ratios were derived from linear mixed-effects models. RESULTS GSK'254 AUC0-τ (geometric least-squares mean ratio [90% confidence interval], 1.14 [1.00-1.29]), Cmax (1.07 [0.92-1.24]) and Cτ (1.17 [1.01-1.35]) were similar when administered alone and with DRV/RTV. Etravirine coadministration decreased GSK'254 AUC0-τ (0.53 [0.48-0.59]), Cmax (0.60 [0.53-0.68]) and Cτ (0.51 [0.39-0.66]). Similar reductions were not observed with GSK'254 + DRV/RTV + ETR (AUC0-τ , 0.94 [0.82-1.09]; Cmax , 0.89 [0.75-1.07]; Cτ , 1.02 [0.89-1.18]). GSK'254 had no meaningful effect on DRV/RTV or ETR concentrations. All reported adverse events (AEs) were grade 1; 3 led to withdrawal and resolved (rash, asymptomatic electrocardiogram T-wave inversion, periorbital oedema). Most common AEs were diarrhoea (n = 9) and headache (n = 7). No deaths or serious AEs occurred. CONCLUSION GSK'254 pharmacokinetics was not meaningfully affected by DRV/RTV or DRV/RTV + ETR, but were reduced with only ETR; no new tolerability concerns were observed.

Abstract
OBJECTIVES Treatment failures to modern antiretroviral therapy (ART) raise concerns, as they could reduce future options. Evaluations of occurrence of multiple failures to modern ART are missing and their significance in the long run is unclear. METHODS People with HIV (PWH) in the ICONA cohort who started a modern first-line ART were defined as 'difficult to treat' (DTT) if they experienced ≥1 among: i) ≥2 VF (2 viral loads, VL>200 copies/mL or 1 VL>1000 copies/mL) with or without ART change; ii) ≥2 treatment discontinuations (TD) due to toxicity/intolerance/failure; iii) ≥1 VF followed by ART change plus ≥1 TD due to toxicity/intolerance/failure. A subgroup of the DTT participants were matched to PWH that, after the same time, were non-DTT. Treatment response, analysing VF, TD, treatment failure, AIDS/death, and SNAE (Serious non-AIDS event)/death, were compared. Survival analysis by KM curves and Cox regression models were employed. RESULTS Among 8061 PWH, 320 (4%) became DTT. Estimates of becoming DTT was 6.5% (95% CI: 5.8-7.4%) by 6 years. DTT PWH were significantly older, with a higher prevalence of AIDS and lower CD4+ at nadir than the non-DTT. In the prospective analysis, DTT demonstrated a higher unadjusted risk for all the outcomes. Once controlled for confounders, significant associations were confirmed for VF (aHR 2.23, 1.33-3.73), treatment failure (aHR 1.70, 1.03-2.78), and SNAE/death (aHR 2.79, 1.18-6.61). CONCLUSION A total of 6.5% of PWH satisfied our definition of DTT by 6 years from ART starting. This appears to be a more fragile group who may have higher risk of failure.

Abstract
Aim of this study was to assess the predictors of virological failure (VF) among patients living with HIV (PLWHIV) switching from an effective first-line antiretroviral therapy (ART) regimen, and to evaluate the emergence of resistance-associated mutations. All adult patients enrolled in the Antiviral Response Cohort Analysis cohort who started ART after 2010, with at least 6 months of virological suppression (VS) before ART switch and with an available genotypic resistance test (GRT) at baseline were included. Thirty-two patients out of the 607 PLWHIV included (5.3%) experienced VF after a median of 11 months from ART switch. Younger age (adjusted Hazard Ratio [aHR] 0.96, 95% confidence interval [CI] 0.92-0.99, p = .023), being male who have sex with male (aHR 0.15, 95% CI 0.03-0.69, p = .014), and longer time from VS to ART switch (aHR 0.97, 95% CI 0.95-1.00, p = .021) resulted protective toward VF, while receiving a first-line regimen containing a backbone other than ABC/3TC or TXF/FTC (aHR 3.61, 95% CI 1.00-13.1, p = .050) and a boosted protease inhibitor as anchor drug (aHR 3.34, 95% CI 1.20-9.28, p = .021) were associated with higher risk of VF. GRT at the moment of VF was available only for 13 patients (40.6%). ART switch in patients with stable control of HIV infection is a safe practice, even if particular attention should be paid in certain cases of patients switching from regimens containing low-performance backbones or protease inhibitors.

Abstract
Data on the long-term durability of rilpivirine (RPV) are still scarce. A two-center retrospective study was performed, including all people living with HIV (PLWH) treated with tenofovir disoproxil fumarate/emtricitabine (TDF/FTC)/RPV or tenofovir alafenamide (TAF)/FTC/RPV in the period January 2013-December 2019. Aims of the study were to assess the rate of discontinuation of the RPV single-tablet regimen (STR) and identify factors associated with the risk of discontinuation according to Cox's regression analysis. A total of 684 PLWH were enrolled. Mean duration of RPV-STR treatment was 192.5 (±99.5) weeks for 123 antiretroviral therapy (ART)-naïve participants (18%) and 173.3 (± 85.6) weeks for 561 ART-experienced study participants (82%). During the study period, the incidence of discontinuation was 7.7 per 100 person-years. The estimated proportions of discontinuation after 48 and 96 weeks were 5.6% and 13.4%, respectively. Causes of discontinuation were loss to follow-up (30%), side effects (15%), ART optimization (14%), virological failure (VF) (12%), death or transfer to another center (9%), low adherence (7%), drug interactions (6%), simplification to dual therapy (3%), and unknown (3%). No differences were observed in cumulative probability of discontinuation between ART-naïve and -experienced PLWH. Heterosexual (hazard ratio [HR] 3.0, 95% confidence interval [CI] 1.4-6.8) and mother-to-child (HR 5.3, 95% CI 1.8-15.3) transmission of HIV infection and history of previous VF (HR 1.7, 95% CI 1.2-2.5) were associated with higher risk of discontinuation. High RPV-STR effectiveness and durability were confirmed in our real-life population of PLWH. Given these data, RPV has the potential to be a drug for life in patients selected according to current guidelines.

Minimum redundancy maximal relevance gene selection of apoptosis pathway genes in peripheral blood mononuclear cells of HIV-infected patients with antiretroviral therapy-associated mitochondrial toxicity.

Abstract
BACKGROUND We previously identified differentially expressed genes on the basis of false discovery rate adjusted P value using empirical Bayes moderated tests. However, that approach yielded a subset of differentially expressed genes without accounting for redundancy between the selected genes. METHODS This study is a secondary analysis of a case-control study of the effect of antiretroviral therapy on apoptosis pathway genes comprising of 16 cases (HIV infected with mitochondrial toxicity) and 16 controls (uninfected). We applied the maximum relevance minimum redundancy (mRMR) algorithm on the genes that were differentially expressed between the cases and controls. The mRMR algorithm iteratively selects features (genes) that are maximally relevant for class prediction and minimally redundant. We implemented several machine learning classifiers and tested the prediction accuracy of the two mRMR genes. We next used network analysis to estimate and visualize the association among the differentially expressed genes. We employed Markov Random Field or undirected network models to identify gene networks related to mitochondrial toxicity. The Spinglass model was used to identify clusters of gene communities. RESULTS The mRMR algorithm ranked DFFA and TNFRSF1A, two of the upregulated proapoptotic genes, on the top. The overall prediction accuracy was 86%, the two mRMR genes correctly classified 86% of the participants into their respective groups. The estimated network models showed different patterns of gene networks. In the network of the cases, FASLG was the most central gene. However, instead of FASLG, ABL1 and LTBR had the highest centrality in controls. CONCLUSION The mRMR algorithm and network analysis revealed a new correlation of genes associated with mitochondrial toxicity.

Abstract
BACKGROUND To assess the impact of syphilis infection on the risk of HIV-RNA elevation in people living with HIV (PLWH) with current HIV-RNA ≤50 copies/mL. SETTING The Italian Cohort Naive Antiretrovirals. METHODS All PLWH (2009-2020) under antiretroviral treatment with at least 2 consecutive HIV-RNA values ≤50 copies/mL before the date of syphilis diagnosis and at least 1 HIV-RNA determination after the syphilis event were enrolled. A control group of PLWH without syphilis was matched for mode of HIV transmission. Outcomes were defined using the first HIV-RNA measure in the time window ranging between -2 and +6 months of the diagnosis/index date. The primary outcome used a single value >200 copies/mL to define HIV-RNA elevation associated with risk of transmission. The association between syphilis infection and the protocol defined outcome was evaluated using logistic regression analysis. RESULTS Nine hundred twenty-six PLWH with a syphilis event were enrolled and matched with a random sample of 1370 PLWH without syphilis. Eighteen of the 926 (1.9%) with syphilis had ≥1 HIV-RNA >200 copies/mL in the window vs. 29/1370 (2.1%) of the not exposed (P = 0.77). In the multivariable analysis adjusted for age, year of diagnosis/index date, and clinical site, syphilis infection was not associated with the risk of HIV-RNA >200 copies/mL (adjusted odds ratio 0.81; 95% confidence interval 0.43-1.52, P = 0.508). CONCLUSIONS We did not find any evidence for an association between syphilis infection and viral elevation >200 copies/mL.

Abstract
This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-11.5] per 100 person-years, similar in most regimens, with the apparent exception of tenofovir alafenamide/emtricitabine+DTG (p < 0.0001). In the multivariable Cox regression model, non-Caucasian ethnicity, age ≥50 years, and lower estimated glomerular filtration rate (eGFR) were associated with a higher probability of DTG interruption. The incidence rate of virological failure was 0.4 (95% CI 0.2-0.7) per 100 person-years, while the estimated discontinuation rate for AEs was 4.0 (3.2-4.9) per 100 person-years. Thirty-four DTG interruptions were due to grade ≥3 events (10 central nervous system, 6 hypersensitivity, 3 renal, 3 myalgia/asthenia, 3 abdominal pain, 2 gastrointestinal, and 7 other events). People with lower body mass index, age ≥50 years, and lower eGFR were at higher risk of AEs, while dual combinations were protective (HR 0.41 compared with abacavir/lamivudine/DTG, 95% CI 0.22-0.77). In this prospective observational study, we found high DTG durability and a low rate of virological failures. Dual therapies seemed protective toward AEs and might be considered, when feasible, a suitable option to minimize drug interactions and improve tolerability.

Durability of rilpivirine-based versus integrase inhibitor-based regimens in a large cohort of naïve HIV-infected patients starting antiretroviral therapy. Int J Antimicrob Agents 2021; 58:106406. [PMID: 34293454 DOI: 10.1016/j.ijantimicag.2021.106406] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 06/09/2021] [Accepted: 07/03/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Comparisons between rilpivirine (RPV) and integrase strand transfer inhibitors (INSTIs) in antiretroviral therapy (ART)-naïve HIV-infected individuals are currently lacking. This study aimed to compare, in an observational cohort setting, the durability of treatment with RPV-based and INSTI-based first-line regimens. METHODS Patients who started first-line ARTs based on RPV or INSTIs, with HIV-RNA < 100 000 copies/mL and CD4 cell count > 200 cells/μL were included. The primary endpoint was the cumulative probability of treatment failure (TF = virological failure [confirmed HIV-RNA > 50 copies/mL] or discontinuation of the anchor drug in the regimen), as assessed by the Kaplan-Meier method. A multivariable Cox regression was used to control for potential confounding. RESULTS Of the 1991 included patients, 986 started ART with an RPV-based regimen and 1005 with an INSTIs-based regimen. The median (IQR) follow-up was 20 (10, 35) months. The cumulative 2-year probability of TF with RPV (9.1% [95% 7.2, 11.1]) was lower than that observed in the INSTIs group (16.6% [13.8, 19.4], P = 0.0002) but not when compared with dolutegravir (DTG) alone. Starting ART with an INSTIs-based regimen vs. RPV was associated with a higher risk of TF after controlling for potential confounding factors (adjusted hazard ratio, AHR [95% CI]: 1.64 [1.28, 2.10]; P < 0.001). The results were similar when restricting the analysis to single-tablet regimens, although the probability of virological success was higher for INSTIs and DTG. CONCLUSIONS In ART-naïve patients with low viral loads and high CD4 counts, the risk of treatment failure was lower in those who started RPV-based vs. INSTIs-based regimens other than DTG-based ones.

Abstract
Introduction Different single-tablet regimens (STRs), containing one or two nucleoside reverse transcriptase inhibitors (NRTIs) plus an anchor drug, are available for the use in naïve, HIV-infected patients. Despite some restrictions in the use of particular regimens in certain situations (e.g., HBV coinfection), International guidelines do not provide indications to prefer any regimen over others concerning the tolerability profile. We aimed to assess advantages and disadvantages of the most prescribed STRs.Areas covered An extensive review of articles published in English language was conducted on PubMed, looking for evidence about STRs in naïve, HIV-infected population. Safety outcomes of registrational trials were assessed, giving priority to studies directly comparing STRs included in our research (abacavir/lamivudine/dolutegravir, tenofovir alafenamide/emtricitabine/bictegravir, lamivudine/dolutegravir, tenofovir alafenamide/emtricitabine/darunavir/cobicistat, tenovofir disoproxil fumarate/lamivudine/doravirine). Data from cohort studies and meta-analyses were also assessed, extrapolating the main evidence about the combinations of interest.Expert opinion Integrase inhibitors (InsTIs)-based regimens have few interruptions for adverse events and few drug-related adverse events, with tenofovir alafenamide/emtricitabine/dolutegravir and lamivudine/dolutegravir being the most tolerable ones. However, neuropsychiatric adverse events and metabolic issues could prompt the alternative use of darunavir or doravirine-based combinations, even if a superior safety profile of these combinations over InSTIs has yet to be demonstrated.

Abstract
Background The aim was to evaluate the hepatitis C virus (HCV) cascade of care in the general population (GP) and in two high-risk populations: patients with diabetes mellitus (DM) and substance users (AS) in treatment in Reggio Emilia Province, Italy. Methods A population-based cross-sectional study was conducted that included 534,476 residents of the Reggio Emilia Province, of whom 32,800 were DM patients and 2726 AS patients. Age-adjusted prevalence was calculated using the direct method of adjustment based on the age-specific structure of EU population. Results The prevalence of HCV testing was 11.5%, 13.8%, and 47.8% in GP, DM, and AS patients respectively, while HCV prevalence was 6.5/1000, 12.6/1000, and 167/1000, respectively. The prevalence of HCV RNA positivity was 4.4/1000, 8.7/1000, and 114/1000 in the three populations, respectively. The rates of HCV RNA-positive individuals not linked to care were 27.9%, 27.3%, and 26% in GP, DM, and AS patients, respectively, while the rates of those cured or cleared were 70.9%, 71%, and 69.9%, respectively. The prevalence of HCV testing was higher for females of reproductive age than for males the same age: 218.4/1000 vs. 74.0/1000, respectively. While more foreigners than Italians underwent the HCV test and were HCV positive, fewer foreigners than Italians received HCV treatment and were cured. Conclusions The low HCV testing and linkage to care rates remain an important gap in the HCV cascade of care in Northern Italy. The prevalence of cured/cleared residents remains lower among foreigners than among Italians.

Is It Feasible to Impact on Smoking Habits in HIV-Infected Patients? Mission Impossible From the STOPSHIV Project Cohort. J Acquir Immune Defic Syndr 2020; 83:496-503.

Abstract
OBJECTIVE Assessment of the feasibility and effectiveness of a brief intervention for smoking cessation in people living with HIV (PLWH). SETTING Multicenter cohort prospective study involving PLWH from 10 Italian infectious disease centers. METHODS During routine HIV care, clinicians delivered the 5As brief intervention (Ask, Advise, Assess, Assist, Arrange) to each patient who enrolled in the study, following the European AIDS Clinical Society guidelines. At study end, participating clinicians evaluated their own adherence to intervention: "standard" if counseling was delivered in at least half of the follow-up visits, "soft" if less. The main outcome measure was smoking abstinence ≥6 months. Abstinence predictors were evaluated using a Cox-proportional hazard regression model. RESULTS One thousand eighty-seven PLWH-patients (age 47.9 ± 10.8, male 73.5%) were followed for a median of 23 months (interquartile range 21-25). At baseline, current smokers were 561 (51.6%). Standard intervention was performed in 4 of 10 centers and included 343 smokers; soft intervention was performed in 6 centers (218 smokers). At last visit, 35 patients in standard (10.8%) and 6 in soft intervention (2.8%) achieved self-reported tobacco abstinence ≥6 months (P = 0.0009). Overall, the 5As intervention led to 7.3% 6-month interruptions. In the multivariable analysis, significant predictors for 6-month smoking cessation were: lower Fagerström score, stage of change (preparation/contemplation vs. precontemplation), and standard intervention. CONCLUSION Adherence to the 5As brief intervention emerged as a critical factor for success. In fact, compared with soft intervention, the standard intervention significantly increased abstinence, highlighting that clinicians need more time and supporting tools to encourage PLWH to quit smoking.

Abstract
OBJECTIVES To evaluate the incidence and risk factors for liver enzyme elevations (LEE) in patients initiating first-line ART in the ICONA prospective observational cohort, between June 2009 and December 2017. PATIENTS AND METHODS In total, 6575 ART-naive patients were selected, initiating two NRTIs with the third drug being a boosted PI (n=2436; 37.0%), an NNRTI (n=2384; 36.3%) or an integrase strand transfer inhibitor (INSTI) (n=1755; 26.7%). HBV surface antigen and HCV RNA were detected in 3.9% and 5.8% of the study population. Inverse probability weighted Cox regression analysis was used to calculate the HRs, according to first-line regimen, for LEE, defined as ALT or AST increases of ≥2.5× upper limit of normal (ULN) for patients with normal baseline values or ≥2.5× baseline for patients with higher baseline values. RESULTS One hundred and eighty-three LEE occurred over 20722 patient-years of follow-up. After adjusting for the main confounders, the risk of LEE halved with INSTIs compared with NNRTIs (HR 0.46, 95% CI 0.25-0.86), with a significant reduction in the raltegravir group (HR 0.11, 95% CI 0.02-0.84 using the NNRTI class as reference). HRs for LEE were significantly higher in subjects with HBV or HCV coinfection, in patients with poorly controlled HIV infection and in those who acquired HIV through homosexual transmission. CONCLUSIONS In our study, INSTI use almost halved the risk of LEE compared with other regimens. This finding could be particularly important for choosing ART in patients with risk factors for liver toxicity such as HCV and HBV coinfections.

Abstract
BACKGROUND Women face unique complexities in HIV treatment yet are underrepresented in antiretroviral therapy (ART) studies. OBJECTIVE This analysis assessed the one-year durability of the first integrase strand transfer inhibitor (INSTI)-based regimens prescribed to women in a large cohort of patients living with HIV in care. METHODS Women with HIV who initiated their first INSTI-containing regimen between 08/12/2013 and 11/30/2015 were identified in the OPERA cohort, a collaboration of 79 US outpatient clinics. Discontinuation within the first year of treatment with an INSTI was compared between dolutegravir (DTG), raltegravir (RAL) and elvitegravir (EVG), using multivariable Cox regression and Kaplan- Meier estimates. Virologic response and regimen modifications were described and compared across INSTIs. RESULTS A total of 537 treatment-naïve (DTG: 39%, EVG: 48%, RAL: 13%) and 878 treatmentexperienced (DTG: 57%, EVG: 29%, RAL: 13%) women were analyzed. In the first twelve months after initiation, women taking EVG or RAL were more likely to discontinue their initial INSTI than those taking DTG among both treatment-naïve (adjusted hazard ratio EVG vs. DTG: 1.59 (95% CI: 1.09, 2.39); RAL vs. DTG: 2.46 (1.49, 4.05)) and treatment-experienced women (EVG vs. DTG: 1.39 (1.02, 1.88); RAL vs. DTG: 2.17 (1.51, 3.12)). Following discontinuation of the initial INSTI, women commonly switched to a regimen containing a different drug from the INSTI class (treatment-naïve DTG: 34%, RAL: 33% EVG: 41%; treatment-experienced DTG: 23%, RAL: 19% EVG: 41%). CONCLUSION In treatment-naïve and treatment-experienced women living with HIV, women taking DTG had the lowest risk for early (≤1 year) discontinuation.

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.

Brief Report: Kidney Dysfunction Does Not Contribute Significantly to Antiretroviral Therapy Modification in Treatment-Naive PLWH Receiving Initial ART. J Acquir Immune Defic Syndr 2019; 81:e6-e9.

Abstract
BACKGROUND Antiretroviral therapy (ART) durability, time to modification or cessation, has declined. The study objective was to determine whether kidney dysfunction is contributing to reduced durability. METHODS This retrospective follow-up study of CNICS evaluated treatment-naive PLWH initiating ART between 2007 and 2014. Regimen modification was defined as cessation/modification of any part of the 3-drug ART regimen. We evaluated the role of kidney dysfunction in initial regimen modification as both a mediator and effect measure modifier. Associations of the variables with the ART modification were examined using univariable and multivariable Cox proportional hazard models. RESULTS Of 4515 PLWH included in the analysis, 1967 modified their ART. Of those receiving TDF-based ART (n = 3888), 1580 (41%) modified their regimen compared with 387 (62%) receiving other regimens. Overall, the median eGFR decreased by 5 mL/min/1.73 m (quartiles: first = -16, third = 0) from baseline to follow-up. Of the 128 patients with low baseline eGFR (<60 mL/min/1.73 m), the final eGFR remained low in 73% while it increased to above 60 mL/min/1.73 m in 27%. Of the 4387 with normal baseline eGFR, only 135 (3%) had a final eGFR <60 mL/min/1.73 m. Those with low eGFR at the baseline and/or final visits were more likely to modify ART than others (hazards ratio = 1.75, 95% confidence interval: 1.39 to 2.19, P < 0.001). Relative to other regimens, TDF-based ART was less likely to be modified when accounting for numerous clinical and demographic traits. CONCLUSIONS For patients in our study initiated on ART, including TDF-based ART, in the last decade, kidney dysfunction is not a major factor leading to regimen modification.

Abstract
BACKGROUND Antiretroviral therapy (ART) has significantly reduced HIV-related morbidity and mortality. However, therapeutic benefit of ART is often limited by delayed drug-associated toxicity. Nucleoside reverse transcriptase inhibitors (NRTIs) are the backbone of ART regimens. NRTIs compete with endogenous deoxyribonucleotide triphosphates (dNTPs) in incorporation into elongating DNA chain resulting in their cytotoxic or antiviral effect. Thus, the efficacy of NRTIs could be affected by direct competition with endogenous dNTPs and/or feedback inhibition of their metabolic enzymes. In this paper, we assessed whether the levels of ribonucleotides (RN) and dNTP pool sizes can be used as biomarkers in distinguishing between HIV-infected patients with ART-induced mitochondrial toxicity and HIV-infected patients without toxicity. METHODS We used data collected through a case-control study from 50 subjects. Cases were defined as HIV-infected individuals with clinical and/or laboratory evidence of mitochondrial toxicity. Each case was age, gender, and race matched with an HIV-positive without evidence of toxicity. We used a range of machine learning procedures to distinguish between patients with and without toxicity. Using resampling methods like Monte Carlo k-fold cross validation, we compared the accuracy of several machine learning algorithms applied to our data. We used the algorithm with highest classification accuracy rate in evaluating the diagnostic performance of 12 RN and 14 dNTP pool sizes as biomarkers of mitochondrial toxicity. RESULTS We used eight classification algorithms to assess the diagnostic performance of RN and dNTP pool sizes distinguishing HIV patients with and without NRTI-associated mitochondrial toxicity. The algorithms resulted in cross-validated classification rates of 0.65-0.76 for dNTP and 0.72-0.83 for RN, following reduction of the dimensionality of the input data. The reduction of input variables improved the classification performance of the algorithms, with the most pronounced improvement for RN. Complex tree-based methods worked the best for both the deoxyribose dataset (Random Forest) and the ribose dataset (Classification Tree and AdaBoost), but it is worth noting that simple methods such as Linear Discriminant Analysis and Logistic Regression were very competitive in terms of classification performance. CONCLUSIONS Our finding of changes in RN and dNTP pools in participants with mitochondrial toxicity validates the importance of dNTP pools in mitochondrial function. Hence, levels of RN and dNTP pools can be used as biomarkers of ART-induced mitochondrial toxicity.

Mao J, Johnson MP, McPheeters JT, Prajapati G, Beyer AP. Healthcare resource utilization and costs in patients with HIV-1 who switched first-line antiretroviral therapy. Curr Med Res Opin 2019; 35:1945-1953.

Abstract
Objectives: This study compared healthcare utilization and costs associated with switching the first-line protease inhibitor (PI) or non-nucleoside reverse transcriptase inhibitor (NNRTI) based antiretroviral (ARV) regimen due to reasons other than virologic failure among patients with HIV-1. Methods: This was a retrospective analysis of commercial and Medicare Advantage with Part D enrollees in two US administrative claims databases. The study population comprised adults with HIV-1 infection initiating antiretroviral therapy (ART) on PI- or NNRTI-containing regimens from 1 January 2006 to 31 December 2015. Patients with a subsequent change in anchor agent were assigned to the switch cohort; the non-switch cohort was constructed using propensity score matching of three non-switching patients for each patient in the switch cohort. Patient characteristics and per patient per month healthcare resource utilization and costs were compared between the cohorts during the pre-switch, switch (15 days before and after switching) and post-switch periods. Costs during the switch period were also estimated with a multivariable-adjusted model. Results: The matched study population consisted of 1204 patients who switched their first-line PI- or NNRTI-based regimen and 3612 patients who did not. Compared with the non-switch cohort, patients who switched had higher healthcare resource utilization during the pre-switch, switch and post-switch periods. Mean unadjusted non-ART costs in the switch cohort were nearly double ($2944 versus $1530, p < .001), more than double ($2562 versus $1215, p < .001) and 1.5 times higher ($1473 versus $968, p < .001) than costs in the non-switch cohort in the pre-switch, switch and post-switch periods, respectively. Conclusions: Patients with HIV-1 who initiated PI- or NNRTI-based regimens and switched ARTs for reasons other than virologic failure used more healthcare resources and incurred greater costs relative to patients in the non-switch cohort. This study highlights the importance of initiating patients on appropriate first-line ART to avoid the need to switch due to reasons other than virologic failure.

Abstract
Background Study aim was to evaluate the safety and durability of darunavir/cobicistat (DRV/c) in a real life setting. Methods Multicentre prospective cohort study performed in the context of SCOLTA (Surveillance Cohort Long-Term Toxicity Antiretrovirals). Patients were evaluated at baseline, week 24 and 48. Changes were evaluated using the paired t test or signed rank test. The multivariable analysis was performed using a general linear model, after ranking of not normally distributed variables. Results A total of 249 patients were included, 72 (29%) were in DRV/c-based dual therapies (DT). Hypercholesterolemia, HC, (total cholesterol (TC) ≥ 200 mg/dL or low density-C (LDL-C) ≥ 130 or statin use) was present in 121 (48.6%) and hypertriglyceridemia, (triglycerides (TG) ≥ 200 mg/dl or fibrate use) in 41 (16.5%) patients. Blood lipid profile did not change significantly in either the global population or patients with HC. After a median observation of 17 months (IQR 13–20), 59 (25.3%) patients discontinued DRV/c, of which 13 were in DT. The durability DT resulted higher than that of triple therapy (log-rank test p = 0.01). Main reasons for stopping DRV/c were simplification (15 patients), adverse events (13 patients), planned discontinuation for treatment initiation with DAA (4 patients), treatment failure (2 patients); death (2 patients), other causes (10 patients). Twenty-six were lost to follow-up. Conclusions DRV/c was safe and well tolerated. Dual therapies showed a better profile of tolerability and a longer durability compared to triple therapies.

Efficacy and safety of dolutegravir-based regimens in advanced HIV-infected naïve patients: results from a multicenter cohort study. Antiviral Res 2019; 169:104552. [PMID: 31283942 DOI: 10.1016/j.antiviral.2019.104552] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 06/21/2019] [Accepted: 07/04/2019] [Indexed: 10/26/2022]
Abstract
The aims were to describe efficacy and tolerability of regimens containing dolutegravir (DTG) in advanced ART-naïve people living with HIV (PLHIV) from the clinical practice. The frequency of Immune Reconstitution Inflammatory Syndrome (IRIS), the estimated time of discontinuation of the first ART regimen and the time to reach virological suppression in a multicenter cohort of AIDS-presenters or late-presenters with CD4 <350/μL were assessed. We included 272 PLHIV: 120 (44%) AIDS-presenters and 152 (56%) late-presenters. The most frequent AIDS-defining event was Pneumocystis jirovecii pneumonia in 41 (34%). One hundred-thirty-two PLHIV (48%) started first-line cART regimens including DTG and 140 PLHIV (52%) were treated with cART regimens without DTG. One-hundred-eighty-two (67%) individuals discontinued their first-line regimen: 109 (60%) for simplification, 32 (18%) for toxicities, 4 (2%) for drug-drug interactions, 37 (20%) for other reasons. DTG was interrupted in 19/132 (14%) PLHIV: 13 (68%) for adverse events (5 intolerance, 4 gastrointestinal disorders and 4 neurological symptoms), 2 (11%) for proactive switch and 4 (21%) for medical/individual choice. IRIS was reported in 13 (5%) AIDS-presenters without differences between arms. During a median observation time of 16 months (IQR 5-24), HIV-1 RNA<50 copies/mL was achieved in 95/132 (72%) individuals on DTG-based regimen and in 92/140 (66%) individuals with other regimens. The 12-month estimated probability of DTG interruption was 14% (95% CI 11-17). The results demonstrated the low risk for IRIS and the high potency, good tolerability and safety of DTG in our population of advanced naïve PLHIV.

Combination of Tenofovir and Emtricitabine with Efavirenz Does Not Moderate Inhibitory Effect of Efavirenz on Mitochondrial Function and Cholesterol Biosynthesis in Human T Lymphoblastoid Cell Line. Antimicrob Agents Chemother 2018; 62:AAC.00691-18. [PMID: 30012753 DOI: 10.1128/aac.00691-18] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Accepted: 07/07/2018] [Indexed: 01/22/2023] Open
Abstract
Efavirenz (EFV), the most popular nonnucleoside reverse transcriptase inhibitor, has been associated with mitochondrial dysfunction in most in vitro studies. However, in real life the prevalence of EFV-induced mitochondrial toxicity is relatively low. We hypothesized that the agents given in combination with EFV moderate the effect of EFV on mitochondrial function. To test this hypothesis, we cultured a human T lymphoblastoid cell line (CEM cells) with EFV alone and in combination with emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF) to investigate the effects on mitochondrial respiration and function and cholesterol biosynthesis. There was a statistically significant concentration- and time-dependent apoptosis, reduction in mitochondrial membrane potential, and increase in production of reactive oxygen species in cells treated with either EVF alone or in combination with TDF plus FTC. Compared to dimethyl sulfoxide-treated cells, EFV-treated cells had significant reduction in oxygen consumption rate contributed by basal mitochondrial respiration and decreased protein expression of electron transport chain complexes (CI, CII, and CIV). Treatment with EFV resulted in a decrease in mitochondrial DNA content and perturbation of more coding genes (n = 13); among these were 11 genes associated with lipid or cholesterol biosynthesis. Our findings support the growing body of knowledge on the effects of EFV on mitochondrial respiration and function and cholesterol biosynthesis. Interestingly, combining TDF and FTC with EFV did not alter the effects of EFV on mitochondrial respiration and function and cholesterol biosynthesis. The gap between the prevalence of EFV-induced mitochondrial toxicity in in vitro and in vivo studies could be due to individual differences in the pharmacokinetics of EFV.

Abstract
OBJECTIVES The aim of this study was to compare the durabilities of efavirenz (EFV) and rilpivirine (RPV) in combination with tenofovir/emtricitabine (TDF/FTC) in first-line regimens. METHODS A multicentre prospective and observational study was carried out. We included all patients participating in the Italian Cohort Naive Antiretrovirals (ICONA) Foundation Study who started first-line combination antiretroviral therapy (cART) with TDF/FTC in combination with RPV or EFV, with a baseline viral load < 100 000 HIV-1 RNA copies/mL. Survival analyses using Kaplan-Meier (KM) curves and Cox regression with time-fixed covariates at baseline were employed. RESULTS Overall, 1490 ART-naïve patients were included in the study, of whom 704 were initiating their first cART with EFV and 786 with RPV. Patients treated with EFV, compared with those on RPV, were older [median 36 (interquartile range (IQR) 30-43) years vs. 33 (IQR 27-39) years, respectively; P < 0.001], were more frequently at Centers for Disease Control and Prevention (CDC) stage C (3.1% vs. 1.4%, respectively; P = 0.024), and had a lower median baseline CD4 count [340 (IQR 257-421) cells/μL vs. 447 (IQR 347-580) cells/μL, respectively; P < 0.001] and a higher median viral load [4.38 (IQR 3.92-4.74) log10 copies/mL vs. 4.23 (IQR 3.81-4.59) log10 copies/mL, respectively], (P = 0.004). A total of 343 patients discontinued at least one drug of those included in the first cART regimen, more often EFV (26%) than RPV (13%), by 2 years (P < 0.0001). After adjustment, patients treated with EFV were more likely to discontinue at least one drug for any cause [relative hazard (RH) 4.09; 95% confidence interval (CI) 2.89-5.80], for toxicity (RH 2.23; 95% CI 1.05-4.73) for intolerance (RH 5.17; 95% CI 2.66-10.07) and for proactive switch (RH 10.96; 95% CI 3.17-37.87) than those starting RPV. CONCLUSIONS In our nonrandomized comparison, RPV was better tolerated, less toxic and showed longer durability than EFV, without a significant difference in rates of discontinuation because of failures.

Abstract
Retention in care is a key feature of the cascade of continuum of care, playing an important role in achieving therapeutic success and being crucial for reduction of HIV transmission. The aim of this study was to evaluate the rate of retention in care in a large referral centre in the North of Italy and to identify predictors associated with failed retention. All new HIV-infected subjects were consecutive enrolled from 1 January 2008 to 31 December 2014. Demographics, immune-virological status, hepatitis co-infection and timing of initiation of combined antiretroviral therapy (cART) data were collected at baseline and at the time of last observation. Failed retention in care was defined as lack of laboratory data, clinical visits and drug dispensation for more than 6 months from the last visit. Cox regression analysis was used. Multivariate analysis of variables with P<0.05 in univariate analysis was performed. We enrolled 269 patients (mean age 46.1 years). Males were 197 (73%), Italian 219 (81%) with mean length of disease of 5.1 years. cART was prescribed for 257 patients (95%). The rate of retention in care was 78.4% and the rate of virological suppression was 75%. Predictors of being loss to follow-up were foreign origin (P = 0.048), CD4+ count <200/mmc (P = 0.001) and not being treated for HIV infection (P = 0.0004). Predictors of cART efficacy were shorter duration of HIV infection and baseline HIV-RNA <100 000 copies/ml. These findings underline the necessity to improve retention in care by identifying groups at increased risk of being loss to follow-up. Retention in care of vulnerable population is crucial to reach 90-90-90 UNAIDS endpoint.

Abstract
OBJECTIVE To evaluate the real world durability of contemporary ART for treatment-naïve people living with HIV (PLWH). DESIGN A retrospective follow-up study in a multisite cohort. METHODS This study of the CNICS (CFAR Network of Integrated Clinical Systems) cohort integrates data from eight Center for AIDS Research (CFARs). PLWH initiating ART between 2007 and 2014 were included. Durability was defined as time from the initiation until discontinuation/modification using Kaplan-Meier survival curves. Cox Proportional Hazards measured associations with various sociodemographic and clinical characteristics. RESULTS Among 5373 PLWH, the initial regimen was modified in 2285 (43%) patients. Efavirenz/emtricitabine/tenofovir (n = 2173, 40%) was the most commonly prescribed initial ART regimen; elvitegravir/cobicistat/emtricitabine/tenofovir became more common after 2012. Median durability for all regimens was 48.6 months. There were statistically significant differences in median durability for NNRTI, InSTI, and protease inhibitor-based regimens, which lasted 61, 44, and 32 months, respectively. Female sex (aHR = 1.4; 95% CI 1.2-1.6), intravenous drug use (aHR = 1.6; 95% CI 1.3-1.9), and CD4 cell count less than 200 cells/μl (aHR = 1.2; 95% CI 1.1-1.3) were significantly associated with regimen modification. Compared with InSTI, those receiving an InSTI/protease inhibitor (aHR = 2.7; 95% CI 2.0-3.7) or protease inhibitor-based ART (aHR = 1.9; 95% CI 1.6-2.2) were significantly more likely to be modified; but those receiving NNRTI (aHR = 1.1; 95% CI 0.9-1.3) were not. CONCLUSION In treatment-naive PLWH, NNRTI and InSTI-based ART were most durable, relative to protease inhibitor and InSTI/protease inhibitor-based ART, and were least likely to be modified/discontinued. A greater understanding of reasons for regimen modification/discontinuation is needed to analyze contemporary regimen durability.

Abstract
To evaluate incidence rates of and predictors for any antiretroviral (ART) drug discontinuation by HCV infection status in a large Italian cohort of HIV infected patients. All patients enrolled in ICONA who started combination antiretroviral therapy (cART) containing abacavir or tenofovir or emtricitabine or lamivudine plus efavirenz or rilpivirine or atazanavir/r or darunavir/r (DRV/r) or lopinavir/r or dolutegravir or elvitegravir or raltegravir were included. Multivariate Poisson regression models were used to determine factors independently associated with single ART drug discontinuation. Inverse probability weighting method to control for potential informative censoring was applied. Data from 10,637 patients were analyzed and 1,030 (9.7%) were HCV-Ab positive. Overall, there were 15,464 ART discontinuations due to any reason in 82,415.9 person-years of follow-up (PYFU) for an incidence rate (IR) of 18.8 (95% confidence interval [95%CI] 18.5-19.1) per 100 PYFU. No difference in IR of ART discontinuation due to any reason between HCV-infected and -uninfected patients was found. In a multivariable Poisson regression model, HCV-infected participants were at higher risk of darunavir/r discontinuation due to any reason (adjusted incidence rate ratio = 1.5, 95%CI 1.01-2.22, p value = 0.045) independently of demographics, HIV-related, ART and life-style factors. Among DRV/r treated patients, we found that HCV-viremic patients had twice the risk of ART discontinuation due to any reason than HCV-aviremic patients. In conclusion, HIV/HCV coinfected patients had a marginal risk increase of DRV/r discontinuation due to any reason compared with those without coinfection.

Abstract
OBJECTIVES Five to eight per cent of HIV-positive individuals initiating abacavir (ABC) experience potentially fatal hypersensitivity reactions (HSRs). We sought to describe the proportion of individuals initiating ABC and to describe the incidence and factors associated with HSR among those prescribed ABC. METHODS We calculated the proportion of EuroSIDA individuals receiving ABC-based combination antiretroviral therapy (cART) among those receiving cART after 1 January 2009. Poisson regression was used to identify demographic, and current clinical and laboratory factors associated with ABC utilization and discontinuation. RESULTS Between 2009 and 2016, of 10 076 individuals receiving cART, 3472 (34%) had ever received ABC-based cART. Temporal trends of ABC utilization were also heterogeneous, with 28% using ABC in 2009, dropping to 26% in 2010 and increasing to 31% in 2016, and varied across regions and over time. Poisson models showed lower ABC utilization in older individuals, and in those with higher CD4 cell counts, higher cART lines, and prior AIDS. Higher ABC utilization was associated with higher HIV RNA and poor renal function, and was more common in Central-East and Eastern Europe and lowest during 2014. During 779 person-years of follow-up (PYFU) in 2139 individuals starting ABC after 1 January 2009, 113 discontinued ABC within 6 weeks of initiation for any reason [incidence rate (IR) 14.5 (95% confidence interval (CI) 12.1, 17.5) per 100 PYFU], 13 because of reported HSR [IR 0.3 (95% CI 0.1, 1.0) per 100 PYFU] and 35 because of reported HSR/any toxicity [IR 4.5 (95% CI 3.2, 6.3) per 100 PYFU]. There were no factors significantly associated with ABC discontinuation because of reported HSR/any toxicity. CONCLUSIONS ABC remains commonly used across Europe and the incidence of discontinuation because of reported HSR was low in our study population.

Abstract
The study was designed to investigate the median duration of second antiretroviral regimens and factors associated with early discontinuation in HIV patients who switched with an undetectable viral load. We conducted a retrospective analysis of the Italian Cohort Naive Antiretrovirals Foundation Study (ICONA), which collects data throughout the country. Patients who started first antiretroviral therapy (ART) after January 1, 2008 in any center involved in this cohort and then switched to a second regimen were included in the study. Second ART failure was described as two HIV-RNA >200 copies/mL or the discontinuation of any drug. Statistical analysis was performed utilizing Kaplan-Meier curves and Cox regression model. The study population included 835 patients and the median duration of first ART regimens was 16 months with HIV-RNA undetectable for 13 months. The main causes of switch to second ART regimens were toxicity (42.5%) and simplification (37.5%). The switch mostly involved the third drug (63.5%) and almost one third of the population received a single-tablet regimen (STR) as second treatment (30.6%). The median duration of second ART regimens was 9.2 months and the probabilities of treatment discontinuation at 12, 24, and 36 months were 21%, 35%, and 48.2%, respectively. STR formulations had a protective effect against second ART discontinuation. Almost half of our population needed a third regimen within 3 years, but STR could improve second ART durability.

Abstract
Background Integrase inhibitors have shown better tolerability than other drugs in clinical trials, but some post-marketing data have suggested potential differences among them. Aims We compared rates and reasons for discontinuation of raltegravir-, elvitegravir- and dolutegravir-based regimens in a large cohort of HIV-infected patients. Methods Retrospective analysis of a prospectively followed cohort including all antiretroviral-naive and all virologically suppressed antiretroviral-experienced patients prescribed a first regimen containing raltegravir, elvitegravir or dolutegravir with at least one follow-up visit. Major outcomes were early discontinuation (≤1 year) due to any reason and more specifically due to toxicity. Incidence was calculated as number of episodes per 1000 person-years. Risk factors for discontinuation were assessed by multivariate Cox models. Results Early discontinuations due to any reason were 271 (raltegravir), 168 (elvitegravir) and 264 (dolutegravir) per 1000 patient-years ( P = 0.0821). Early discontinuations due to toxicity were 76 (raltegravir), 103 (elvitegravir) and 81 (dolutegravir) per 1000 patient-years ( P = 0.6792). Overall, the most common toxicities leading to discontinuation were neuropsychiatric, osteomuscular or digestive. Most frequent neuropsychiatric manifestations reported at discontinuation were insomnia, dizziness, headache and anxiety irrespective of the integrase inhibitor. Among discontinuations due to toxicity, neuropsychiatric effects were more common with dolutegravir than with raltegravir or elvitegravir ( P = 0.0046). Age (HR 1.04, 95% CI 1.02-1.07, P = 0.0007) was the only independent risk factor for early discontinuation due to toxicity. Conclusions Discontinuations due to any reason tended to be less common with elvitegravir, but discontinuations due to toxicity did not differ among integrase inhibitors. Neuropsychiatric toxicity leading to drug discontinuation was more frequent with dolutegravir.

Abstract
Background Aim of this study was to evaluate the efficacy and the safety of switching from branded to generic antiretrovirals in patients with HIV-RNA <50 copies/mL. Methods Matched-cohort study of patients followed at a single clinical center. Since September 2014, all patients with HIV-RNA <50 copies/mL who were receiving branded lamivudine or zidovudine/lamivudine or efavirenz were switched to the generic compound (switchers) and matched, in a ratio 1:1, for age (±5 years), gender, anti-HCV antibodies, nadir and (±50 cells/μL) baseline CD4+ count (±100 cells/μL), duration of antiretroviral therapy (±1 year), with patients with HIV-RNA <50 copies/mL, on treatment with unavailable generic compounds (non-switchers). Incidence rates (IR) of different outcomes were calculated and compared by Poisson regression model. A confirmed HIV-RNA ≥50 copies/mL defined virological failure; any change in the antiretroviral regimen was defined as treatment discontinuation. Results Four hundred forty patients were switched to generic compounds (268 [61%] on lamivudine, 65 [15%] on zidovudine/lamivudine, 87 [20%] on efavirenz and 20 [4%] on efavirenz and either lamivudine or zidovudine/lamivudine). Over a median follow-up of 15.0 (12.1–15.7) months, virological failure occurred in four switchers (IR: 0.07 [0.02–0.18]/100-person months of follow-up [PMFU]) and in ten non-switchers (IR: 0.20 [0.10–0.35]/100-PMFU) (p = 0.0003), while treatment discontinuation occurred in 118 switchers (IR: 2.05 [1.70–2.44]/100-PMFU) and in 128 non-switchers (IR: 2.37 [1.99–2.81]/100-PMFU) (p = 0.699). Conclusions After more than one year of follow-up, we found no evidence of increased risk of reduced efficacy or increased toxicity after switching from branded to generic lamivudine or zidovudine/lamivudine or efavirenz.

Abstract
BACKGROUND Nucleos(t)ide reverse transcriptase inhibitors (NRTI) toxicity may represent a threat for long-term success of combined antiretroviral therapy. Some studies have suggested a possible improvement of NRTI-related toxicity after switching to NRTI-sparing regimens. OBJECTIVES We aimed to explore the efficacy and tolerability of switching to darunavir/ritonavir (DRV/r) plus raltegravir (RAL) while having a viral load (VL) ≤50 copies/mL in the clinical setting. STUDY DESIGN Treatment-experienced HIV 1-infected patients enrolled in the ICONA Foundation Study cohort were included if they switched their current regimen to DRV/r + RAL with a HIV-RNA ≤50 copies/mL. Different definitions of virological failure (VF) and treatment failure (TF) were employed. Kaplan-Meier curves and Cox regression models were performed to estimate time to event probability. RESULTS We included 72 HIV-infected patients, 22 (31%) of these were female, 31 (43%) men who have sex with men (MSM) amd 15 (21%) had hepatitis co-infections. Median age was 44 (IQR: 35-50) years amd CD4 count was 389 (IQR 283-606) cells/mmc. Median follow-up time for TF was 24 (IQR 9-31) months. Twenty-five discontinuations occurred (60% simplifications); only 2 (8%) were toxicity-driven (lipid elevations). The probability of VF (confirmed VL >50 copies/mL) was estimated at 7% [95% confidence interval (CI) 1-13%] by 12 and 9% (95% CI 2-16%) by 24 months. When considering TF, we found a probability of stop/intensification/single VL > 200 copies/mL of 13% (95% CI 1-17%) and 22% (95% CI 11-33%) by 12 and 24 months. Female gender (adjusted relative hazard, ARH = 0.10; 95% CI 0.01-0.74; p = 0.024) and older age (AHR = 0.50 per 10 years older; 95% CI 0.25-0.99; p = 0.045) were associated with a lower risk of TF. A previous PI failure was strongly associated with TF (AHR = 52.6, 95% CI 3.6-779; p = 0.004). CONCLUSIONS DRV/r + RAL is a valuable NRTI-sparing option, especially in female and older patients, with a relatively low risk of VF and good tolerability after 2 years since start in an ART-experienced population. However, previous PI-failure should be a limiting factor for this strategy.

Abstract
The National Free Antiretroviral Treatment Program was implemented in Jiangsu Province, China in 2005. We conducted a retrospective, open cohort study to determine treatment failure rates and associated risk factors. Data were obtained from the national web-based antiretroviral treatment database. WHO criteria were used to define immunologic treatment failure. Kaplan-Meier methods were used to determine treatment failure rates and Cox proportional hazards modeling was used to identify risk factors. A total of 5,083 (87.8%) having at least one CD4 cell count measure were included from 2005 to 2013. Overall, 30.4% had immunologic treatment failure with cumulative treatment failure rates increasing to 50.5% at month 60 and 64.1% at month 90. Factors predicting treatment failure included being treated in the Centers for Disease Control and Prevention system (HR 1.69, 95% CI 1.14-2.50, p = 0.009) or jail hospital (HR 1.20, 95% CI 1.08-1.34, p = 0.001), and having a baseline CD4 count >350 cells/uL (HR 2.37, 95% CI 1.94-2.89. p < 0.001). Immunologic treatment failure was moderate to substantial among treated HIV patients. Providing second-line regimens and shifting treatment providers to professional hospitals should be considered to consolidate gains in averting morbidity and mortality.

Is it still worthwhile to perform quarterly cd4+ t lymphocyte cell counts on hiv-1 infected stable patients? BMC Infect Dis 2017; 17:127.

Abstract
BACKGROUND In the last 20 years routine T CD4+ lymphocyte (CD4+) cell count has proved to be a key factor to determine the stage of HIV infection and start or discontinue of prophylaxis for opportunistic infections. However, several studies recently showed that in stable patients on cART a quarterly CD4+ cell count monitoring results in limited (or null) clinical relevance. The research is intended to investigate whether performing quarterly CD4+ cell counts in stable HIV-1 patients is still recommendable and to provide a forecast of the cost saving that could be achieved by reducing CD4+ monitoring in such a category of patients. METHODS The study is based on data referring to all HIV-infected patients > 18 years of age being treated at two large infectious diseases units located in the metropolitan area of Genoa, Italy. The probability of CD4+ cell counts dropping below a threshold value set at 350 cells/mm3 is assessed using confidence intervals and Kaplan-Meier survival estimates, whereas multivariate Cox analysis and logistic regression are implemented in order to identify factors associated with CD4+ cell count falls below 350 cells/mm3. RESULTS Statistical analysis reveals that among stable patients the probability of maintaining CD4+ >350 cell/mm3 is more than 98%. Econometric models indicate that HCV co-infection and HIV-RNA values >50 copies/mL in previous examinations are associated with CD4+ falls below 350 cells/mm3. Moreover, results suggest that the cost saving that could be obtained by reducing CD4+ examinations ranges from 33 to 67%. CONCLUSIONS Empirical findings shows that patients defined as stable at enrollment are highly unlikely to experience a CD4+ value <350 cell/mm3 in the space/arc of a year. The research supports a recommendation for annual CD4+ monitoring in stable HIV-1 patients.

Abstract
Objectives Persistence with an antiretroviral therapy (ART) regimen for HIV can be defined as the length of time a patient remains on therapy before stopping or switching. We aimed to describe ART persistence in treatment naïve patients starting therapy in the United Kingdom, and to describe differential persistence by treatment regimen. Methods We performed a retrospective cohort study at eight UK centres of ART-naïve adults commencing ART between 2012 and 2015. Aggregate data were extracted from local treatment databases. Time to discontinuation was compared for different third agents and NRTI backbones using incidence rates. Results 1949 patients contributed data to the analysis. Rate of third agent change was 28 per 100 person-years of follow up [95% CI 26–31] and NRTI backbone change of 15 per 100 person-years of follow up [95% CI 14–17]). Rilpivirine, as co-formulated rilpivirine/tenofovir/emtricitabine had a significantly lower discontinuation rate than all other third agents and, excluding single tablet regimens, co-formulated tenofovir/emtricitabine had a significantly lower discontinuation rate than co-formulated abacavir/lamivudine. The reasons for discontinuation were not well recorded. Conclusions Treatment discontinuation is not an uncommon event. Rilpivirine had a significantly lower discontinuation rate than other third agents and tenofovir/emtricitabine a lower rate than co-formulated abacavir/lamivudine.

Abstract
Increased access to highly active antiretroviral therapy (HAART) has made the management of drug toxicities an increasingly crucial component of HIV. This study investigated the effects of adjuvant use of coconut oil and HAART on testicular morphology and seminal parameters in Sprague- Dawley rats. Twelve adult male Sprague-Dawley rats, weighing 153~169 g were distributed into four groups (A–D) and treated as follows: A served as control (distilled water); B (HAART cocktail- Zidovudine, Lamivudine and Nevirapine); C (HAART + Virgin coconut oil 10 mL/kg) and D (Virgin coconut oil 10 mL/kg). After 56 days of treatment, animals were killed and laparotomy to exercise the epididymis for seminal fluid analyses done whilst testicular tissues were processed for histomorphometric studies. Result showed a significant decline in sperm motility (P < 0.05) and count (P < 0.0001) in HAART-treated animals while there was insignificant changes in other parameters in groups C and D except count that was reduced (P < 0.0001) when compared with controls. Histomorphological studies showed HAART caused disorders in seminiferous tubular architecture with significant (P < 0.01) decline in epithelial height closely mirrored by extensive reticulin framework and positive PAS cells. Adjuvant Virgin coconut oil + HAART resulted in significant decrease in seminiferous tubular diameter (P < 0.05), but other morphometric and histological parameters were similar to control or Virgin coconut oil alone (which showed normal histoarchitecture levels). While derangements in testicular and seminal fluid parameters occurred following HAART, adjuvant treatment with Virgin coconut oil restored the distortions emanating thereof.

Abstract
This study aimed to evaluate the efficacy, tolerability and potential savings of combined antiretroviral therapy (cART) simplification from an unboosted protease inhibitor (PI) regimen with atazanavir or fosamprenavir to a single-tablet regimen (STR) based on rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) among HIV-1-infected patients with HIV-1 RNA <50 copies/mL. This was a retrospective, multicentre, open-label, 12-week trial. Plasma HIV-1-RNA levels, CD4+ cell counts, cholesterol, triglycerides, bilirubin, glycaemia, creatinine and physical examination were performed at baseline and at scheduled follow-up. All patient costs were calculated and were estimated for 52 weeks of therapy. Fifty-one patients were enrolled [28 male (54.9%)]. At baseline, 30 patients (58.8%) were treated with FTC/TDF, 20 (39.2%) with abacavir/lamivudine and 1 (2.0%) with lamivudine/zidovudine. Thirty-three patients (64.7%) received atazanavir. All patients maintained HIV-RNA <50 copies/mL; the median CD4+ cell count remained stable. Mean triglycerides decreased from 124 mg/dL (range, 39-625) at enrolment to 108.7 mg/dL (range, 39-561) at study end (P = 0.25). At baseline, mean cholesterol was 172.8 ± 38.1 mg/dL and decreased to 161.9 ± 38.6 mg/dL (P = 0.038); likewise, median total bilirubin decreased from 1.07 mg/dL (range, 0.2-4.7) to 0.6 mg/dL (range, 0.13-3.1) (P <0.001). cART-related annual cost reduction with a STR was €3155.47 per patient (-24%). Non-cART patient management expenses were €402.68 vs. €299.10 for atazanavir or fosamprenavir and STR regimens, respectively. Switching to RPV/FTC/TDF from an unboosted PI in virologically suppressed HIV-infected patients is safe and is associated with a reduction in triglycerides, cholesterol and cART-related costs.
