Abstract
Purpose Integrase inhibitor (INI)-containing regimens are increasingly replacing protease inhibitor(PI)-containing regimens in clinical practice. The aim of this study was to evaluate the determinants of the durability of INI-containing regimens after the switch. Patients and methods We retrospectively analysed all of the people with HIV infection attending the University of Milan’s Infectious Diseases Unit at Luigi Sacco Hospital who were switched from a PI- to an INI-containing regimen between April 2008 and March 2017. The probability of remaining on an INI-containing regimen was estimated using Kaplan-Meier curves, and the baseline clinical predictors of INI-containing regimen durability were assessed using a multivariable Cox proportional hazard regression model. Results Three hundred and twelve patients were included in the analysis. The median time of observation was 21 months (interquartile range 10–36 months). The main reasons for switching from a PI-containing regimen to an INI-containing regimen were toxicities (31.4%) and simplification (31.1%). Univariate analysis revealed no difference in the probability of INI discontinuation between the patients treated with raltegravir, dolutegravir or elvitegravir (p=0.060), but the multivariable Cox regression model showed that the patients treated with dolutegravir were at less risk of discontinuation than those treated with raltegravir (adjusted hazard ratio 0.49, 95% confidence interval 0.26–0.95; p=0.034). Conclusion Switching from a PI- to an INI-containing regimen may be an option for patients under virological control. The patients switched to dolutegravir were less likely to discontinue the INI than those switched to raltegravir. Our findings support this therapeutic strategy and highlight the durability and efficacy of dolutegravir containing-regimens after switching from a PI-containing regimen.

Abstract
: We evaluated the efficacy and safety of a two-drug regimen including dolutegravir (DTG) and unboosted atazanavir (uATV) in 151 HIV-1 infected patients with HIV-RNA of more than 50 copies/ml. During a median follow-up of 62 (42-97) weeks, two virological failures (1%) and 13 treatment discontinuations (9%) occurred; the 48-week probability of virological failure was 0.8% (95% confidence interval 0.2-5.6%). Switch to DTG + uATV may represent a boosting and transcriptase reverse inhibitors sparing otion in individuals with long exposure to antiretroviral therapy and risk of cardiovascular disease.

Abstract
Darunavir/ritonavir (DRV/r) is a second-generation protease inhibitor used in treatment-naïve and -experienced HIV-positive adult patients. To evaluate efficacy and safety in these patient settings, we performed a meta-analysis of randomized controlled trials. We considered eight studies involving 4240 antiretroviral treatment (ART)-naïve patients and 14 studies involving 2684 ART-experienced patients. Regarding efficacy in the ART-naive patients, the virological response rate was not significantly different between DRV/r and the comparator. For the ART-experienced failing patients, the virological response rate was significantly higher with DRV/r than with the comparator (RR 1.45, 95% CI: 1.01-2.08); conversely, no significant differences were found between the treatment-experienced and virologically controlled DRV/r and comparator groups. Regarding safety, the discontinuation rates due to adverse events (AEs) and DRV/r-related serious adverse events (SAEs) did not significantly differ from the rates in the comparator group (RR 0.84, 95% CI: 0.59-1.19 and RR 0.78, 95% CI: 0.57-1.05, respectively). Our meta-analysis indicated that DRV/r-based regimens were effective and tolerable for both types of patients, which was consistent with published data.

Abstract
OBJECTIVES Cobicistat seems to have a low rate of adverse events compared with ritonavir. METHODS This restrospective observational study to evaluated changes in lipid parameters and the percentage of subjects with dyslipidemia in virologically suppressed HIV-infected patients who were receiving a regimen containing darunavir/ritonavir and were then switched from ritonavir to cobicistat, carried out from December 2015 to May 2016, included 299 HIV-1-infected patients who were on stable antiretroviral treatment including darunavir/ritonavir (monotherapy, bitherapy or triple therapy for at least 6 months) and were then switched from ritonavir to cobicistat. Lipid parameters, as well as plasma HIV-1 RNA and CD4 cell counts, were recorded at baseline just before the switch, and 24 weeks after the switch. Patients were stratified according to the presence of hypercholesterolaemia [baseline total cholesterol > 200 mg/dL and/or low-density lipoprotein (LDL) cholesterol > 130 mg/dL] or hypertriglyceridaemia (baseline triglyceride levels > 200 mg/dL). RESULTS Two hundred and ninety-nine patients were enrolled in the study. Fifty-two per cent of the total study population showed dyslipidaemia at baseline. All patients maintained HIV-1 RNA ≤ 50 HIV-1 RNA copies/mL at week 24. No statistically significant changes were seen in CD4 T-cell count from baseline to week 24 [654 (298) to 643 (313) cells/μL; P = 0.173]. When patients were stratified according to the presence of hypercholesterolaemia at baseline (n = 124), significant changes were observed in total cholesterol (P < 0.001), LDL cholesterol (P = 0.047), high-density lipoprotein (HDL) cholesterol (P = 0.002) and triglyceride levels (P = 0.025), and when they were stratified according to the presence of hypertriglyceridaemia at baseline (n = 64), changes from baseline to week 24 in triglyceride level were statistically significant [median (interquartile range) 352 (223, 389) mg/dL at baseline and 229 (131, 279) mg/dL at week 24; P < 0.001]. CONCLUSIONS Cobicistat as a booster of darunavir in HIV-infected subjects had a beneficial effect on the lipid profile in patients with hypercholesterolaemia or hypertrigliceridaemia at baseline.

Abstract
HIV-1-infected patients with suppressed plasma viral loads often require changes to their antiretroviral (ARV) therapy to manage drug toxicity and intolerance, to improve adherence, and to avoid drug interactions. In patients who have never experienced virologic failure while receiving ARV therapy and who have no evidence of drug resistance, switching to any of the acceptable US Department of Health and Human Services first-line therapies is expected to maintain virologic suppression. However, in virologically suppressed patients with a history of virologic failure or drug resistance, it can be more challenging to change therapy while still maintaining virologic suppression. In these patients, it may be difficult to know whether the discontinuation of one of the ARVs in a suppressive regimen constitutes the removal of a key regimen component that will not be adequately supplanted by one or more substituted ARVs. In this article, we review many of the clinical scenarios requiring ARV therapy modification in patients with stable virologic suppression and outline the strategies for modifying therapy while maintaining long-term virologic suppression.

Abstract
Effectiveness data of an unboosted atazanavir (ATV) with abacavir/lamivudine (ABC/3TC) switch strategy in clinical routine are scant.We evaluated treatment outcomes of ATV + ABC/3TC in pretreated subjects in the EuroSIDA cohort when started with undetectable plasma HIV-1 viral load (pVL), performing a time to loss of virological response (TLOVR <50 copies/mL) and a snapshot analysis at 48, 96, and 144 weeks. Virological failure (VF) was defined as confirmed pVL >50 copies/mL.We included 285 subjects, 67% male, with median baseline CD4 530 cells, and 44 months with pVL ≤50 copies/mL. The third drug in the previous regimen was ritonavir-boosted atazanavir (ATV/r) in 79 (28%), and another ritonavir-boosted protease inhibitor (PI/r) in 29 (10%). Ninety (32%) had previously failed with a PI. Proportions of people with virological success at 48/96/144 weeks were 90%/87%/88% (TLOVR) and 74%/67%/59% (snapshot analysis), respectively. The rates of VF were 8%/8%/6%. Rates of adverse events leading to study discontinuation were 0.4%/1%/2%. The multivariable adjusted analysis showed an association between VF and nadir CD4+ (hazard ratio [HR] 0.63 [95% confidence interval [CI]: 0.42-0.93] per 100 cells higher), time with pVL ≤50 copies/mL (HR 0.87 [95% CI: 0.79-0.96] per 6 months longer), and previous failure with a PI (HR 2.78 [95% CI: 1.28-6.04]). Resistance selection at failure was uncommon.A switch to ATV + ABC/3TC in selected subjects with suppressed viremia was associated with low rates of VF and discontinuation due to adverse events, even in subjects not receiving ATV/r. The strategy might be considered in those with long-term suppression and no prior PI failure.

Abstract
For many patients living with HIV-1, the efficacy of combined ART (cART) has made the infection turn to a chronic disease. Because cART is associated with a risk of long-term toxicity, switching patients with virological success to another therapy remains a major issue. Studies undertaken and published over recent years have shown that switching patients exhibiting virological suppression to less-drug regimens (LDR) is a possible option of maintenance strategy. The use of ritonavir-boosted PIs (PI/r) as the backbone of LDR-based maintenance therapy is consistent with their virological potency and a high genetic barrier of resistance. Atazanavir is the most documented PI/r regarding maintenance in dual therapy, with favourable results in terms of virological suppression, tolerance improvement and absence of emergence of mutations. Furthermore, atazanavir is the only commonly prescribed PI that can be used after withdrawal of ritonavir, with maintenance of virological suppression whatever the backbone of associated NRTIs. Based on clinical studies, and taking into account the characteristics of the patients included, one may consider that for any patient with a virological suppression on cART for at least 12 months, with the nadir CD4 >100 cells/mm3 and an absence of encephalitis, an LDR-based maintenance therapy including atazanavir can be considered. Cumulative genotypes must be available to make sure that the LDR will not jeopardize future therapeutic options. The final decision regarding the most appropriate LDR must be guided by the objectives shared by the physician and his/her patient.

Abstract
With more effective and widespread antiretroviral treatment, the overall incidence of AIDS- or HIV-related death has decreased dramatically. Consequently, as patients are aging, cardiovascular disease (CVD) has emerged as an important cause of morbidity and mortality in the HIV population. The incidence of CVD overall in HIV is relatively low, but it is approximately 1.5-2-fold higher than that seen in age-matched HIV-uninfected individuals. Multiple factors are believed to explain this excess in risk such as overrepresentation of traditional cardiovascular risk factors (particularly smoking), toxicities associated with cumulative exposure to some antiretroviral agents, together with persistent chronic inflammation, and immune activation associated with HIV infection. Tools are available to calculate an individual's predicted risk of CVD and should be incorporated in the regular follow-up of HIV-infected patients. Targeted interventions to reduce this risk must be recommended, including life-style changes and medical interventions that might include changes in antiretroviral therapy.

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.

Abstract
We evaluated predictive factors involved in durability and therapeutic failure of atazanavir (ATV)-based antiretroviral regimens with or without ritonavir (r) in real life setting. This retrospective study of HIV-1-positive patients evaluated the factors related to ATV continuance and the time-dependent probability of therapeutic failure (HIV-RNA >200 copies/mL and concomitant discontinuation of ATV). We also investigated the rate of therapeutic failure and the variations in total bilirubin levels from starting unboosted ATV-based regimens. The study involved 1030 patients: 183 treatment-naïve patients (17.8%) started ATV/r (17 subsequently switched to unboosted ATV); 653 (63.4%) switched to ATV/r from previous antiretroviral regimens (121 subsequently switched to unboosted ATV); and 194 (18.8%) switched to unboosted ATV from previous ATV-free regimens. The median ATV follow-up was 28 months (interquartile range 7-56). The risk of ATV discontinuation was significantly lower in patients switched to unboosted ATV from ATV/r (HR 0.45; p < 0.0001). The discontinuation of ATV correlated with female gender (HR 1.26; p = 0.035), use of a zidovudine/didanosine/stavudine containing backbone (HR 1.8; p = 0.004), and a baseline CD4+ cell counts of <200/μL (HR 1.54; p = 0.003), the last of which was also associated with a higher risk of therapeutic failure (HR 2.42; p = 0.001). Total bilirubin levels were significantly lower in the patients switching from ATV/r to unboosted ATV. Unboosted ATV-based therapies are safe and effective options in patients whose immuno-virological conditions are stable, and allow the long-term survival of ATV-containing regimens.

Leibowitch J, Mathez D, de Truchis P, Ledu D, Melchior JC, Carcelain G, Izopet J, Perronne C, David JR. Four days a week or less on appropriate anti-HIV drug combinations provided long-term optimal maintenance in 94 patients: the ICCARRE project. FASEB J 2015; 29:2223-34. [PMID: 25833895 DOI: 10.1096/fj.14-260315] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2014] [Accepted: 02/03/2015] [Indexed: 11/11/2022]
Abstract
Short, intraweekly cycles of anti-HIV combinations have provided intermittent, effective therapy (on 48 patients) (1). The concept is now extended to 94 patients on treatment, 4 days per week or less, over a median of 2.7 discontinuous treatment years per patient. On suppressive combinations, 94 patients volunteered to treatment, 5 and 4 days per week, or reduced stepwise to 4, 3, 2, and 1 days per week in 94, 84, 66, and 12 patients, respectively, on various triple, standard, antiviral combinations, or nonregistered, quadruple, antiviral combinations. Ninety-four patients on treatment 4 days per week aggregated 165 intermittent treatment years; no viral breakthrough was observed over 87 average treatment weeks per patient, 63 of 94 having passed 2.5 intermittent treatment years on any of the antiviral combinations prescribed. On the hyperintermittent treatment of 3, 2, and 1 days per week, HIV RNA surged >50 copies, 4 weeks apart, in 18 instances (6.8 viral escapes/100 hyperdiscontinuous maintenance years). Viral escapes could have been a result of erratic adherence (EA) to regimen or follow-up (3 patients)--drug taken at half of the daily recommended dosage (8 patients) and/or overlooked archival-resistant HIVs from antecedent treatment failures (6 patients). Aside from the above circumstances, HIV unexpectedly rebounded in 3 patients on 2 days per week treatment and 1 patient on 1 day per week treatment, posting 2.2 intrinsic viral escapes/100 highly discontinuous treatment years. All 18 escapes were eventually reversed by 7 days per week salvage combinations, and 11 of 18 patients have been back for a second course of intermittent therapy, 4 days per week or less. Both cell-activation markers on the surface of T lymphocytes and cell-bound HIV DNA levels remained stable or declined. CD4/CD8 ratios rose to ≥1 in 35% of patients, whereas CD4 counts went ≥500/µl in 75%. These values were previously 7 and 40%, respectively, on 7 days per week therapy. In our aging, long, HIV-enduring, multitreated patient cohort, treatment 4 days per week and less over 421 intermittent treatment years reduced prescription medicines by 60%--equivalent to 3 drug-free/3 virus-free remission year per patient--actually sparing €3 million on just 94 patients at the cost of 2.2 intrinsic viral failure/100 hyperintermittent treatment years. At no risk of viral escape, maintenance therapy, 4 days per week, would quasiuniversally offer 40% cuts off of current overprescriptions.

Abstract
OBJECTIVES The objective of this study was to assess the 48-week virological efficacy of atazanavir/ritonavir (ATV/r) monotherapy vs. ATV/r along with two nucleoside reverse transcriptase (NRTIs) in HIV-1 treated individuals with HIV-RNA less than 50 copies/ml. METHODS A multicentre, randomized, open-label, noninferiority trial. HIV-1 treated individuals on ATV/r 300/100 mg along with two NRTIs were randomized to receive ATV/r monotherapy or to maintain their antiretroviral regimen. The primary endpoint was the confirmed viral rebound (CVR: two consecutive HIV-RNA >50 copies/ml) or treatment discontinuation for any reason. Individuals who experienced CVR on ATV/r monotherapy reintroduced NRTIs and discontinued the study if HIV-RNA was more than 50 copies/ml after 12 weeks since reintensification. RESULTS One hundred and three patients enrolled. By week 48, 11 patients in ATV/r arm and two in ATV/r along with two NRTIs experienced CVR; four (8%) patients in ATV/r and eight (15%) in ATV/r along with two NRTIs discontinued. At the 48-week primary efficacy analysis (re-intensification = failure), treatment success was 73% in ATV/r arm and 85% in ATV/r along with two NRTIs [difference -12.1%, 95% confidence interval (95% CI) -27.8 to 2.1]. According to the analysis considering re-intensification is equal to success, treatment success was 92% in ATV/r arm and 85% in the ATV/r along with two NRTIs arm (difference 7.5%, 95% CI -4.7 to 19.8). At CVR, no mutation was observed in ATV/r arm and reintensification with NRTIs was effective in all individuals. Overall, Grade 3-4 (P = 0.003) and grade 3-4 drug-related (P = 0.027) adverse events were less frequent in ATV/r arm. A significant increase in total and low-density lipoprotein (LDL)-cholesterol was observed as well as a significant improvement in high-density lipoprotein (HDL)-cholesterol, fasting glucose, liver fibrosis and alkaline phosphatase was observed in ATV/r monotherapy in comparison with ATV/r along with two NRTIs. CONCLUSION ATV/r monotherapy treatment simplification showed lower virological efficacy in comparison with maintaining triple therapy; NRTIs reintroduction was effective in all the individuals.

Abstract
Despite great advances in antiretroviral therapy in the last decade, several limitations still remain such as adverse effects, lack of adherence and drug-drug interactions. Switching antiretroviral therapy in stable, virologically suppressed patients with the aim of improving tolerability and convenience is an expanding strategy in clinical practice. Several factors need to be taken into consideration when switching a suppressive regimen, such as previous virologic failure, genetic barrier of the new regimen, prior duration of virologic suppression and expected level of adherence. The most frequently used strategies include reductions in the number of pills, drugs or doses. Although switching strategies may be useful, not all the regimens used in clinical practice are based on data from randomized clinical trials and some may not be the best option for certain patients; therefore, therapy should be individualized taking into consideration available information as well as patient and drug characteristics.
