Abstract
OBJECTIVE The study investigated the durability of switched therapy and factors associated with the viral rebound among patients on second-line antiretroviral therapy (ART) in Uganda. DESIGN A retrospective dynamic cohort of adults initiated on second-line ART after virological failure to first-line ART. METHODS Patients on second-line treatment for at least 6 months between 2007 and 2017 were included. Patients were followed, until they experienced a viral rebound (viral load ≥200 copies/ml). Cumulative probability of viral rebounds and factors associated with viral rebound were determined using Kaplan-Meier methods and Cox proportional hazard models. RESULTS One thousand, one hundred and one participants were enrolled of which 64% were women, the median age was 37 years [interquartile range (IQR) 31-43]. The preswitch median CD4 + cell count and viral load were 128 cells/μl (IQR 58-244) and 45 978 copies/ml (IQR 13 827-139 583), respectively. During the 4190.37 person-years, the incidence rate of viral rebound was 83.29 [95% confidence interval (CI) 74.99-92.49] per 1000 person-years. The probability of viral rebound at 5 and 10 years was 0.29 (95% CI 0.26-0.32) and 0.62 (95% CI 0.55-0.69), respectively. The median rebound-free survival was 8.7 years. Young adults (18-24 years) [adjusted hazard ratio (aHR) 2.49, 95% CI 1.32-4.67], preswitch viral load at least 100 000 copies/ml (aHR 1.53, 95% CI 1.22-1.92), and atazanavir/ritonavir (ATV/r)-based second-line (aHR 1.73, 95% CI 1.29-2.32) were associated with an increased risk of viral rebound. CONCLUSION Switched therapies are durable for 8 years after failure of recommended regimens. A high preswitch viral load, ATV/r-based regimens, and young adulthood are risk factors for viral rebound, which underscores the need for more durable regimens and differentiated care services.

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
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.

Curr HIV Res 2020; 17:266-276.

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 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.

Durability of INI-containing regimens after switching from PI-containing regimens: a single-centre cohort of drug-experienced HIV-infected subjects. DRUG DESIGN DEVELOPMENT AND THERAPY 2019; 13:2271-2282.

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.
