BACKGROUND: HIV-1-infected, virologically suppressed adults wanting to simplify or change their non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens may benefit from switching to the single-tablet regimen of elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (E/C/F/TDF). OBJECTIVE: We examined differences in the proportion of participants with HIV-1 RNA < 50 copies/mL (Snapshot analysis), change in CD4 cell count, safety, and patient-reported outcomes in participants switching to E/C/F/TDF from an NNRTI + FTC/TDF (TVD) regimen. METHODS: STRATEGY-NNRTI was a 96-week, phase 3b, randomized, open-label, study examining the efficacy, safety, and tolerability of switching to E/C/F/TDF in virologically suppressed individuals (HIV-1 RNA < 50 copies/mL) on an NNRTI + TVD regimen. Participants were randomized to switch or remain on their NNRTI-based regimen (no-switch). RESULTS: At Week 96, 87% (251/290) of switch and 80% (115/143) of no-switch participants maintained HIV-1 RNA < 50 copies/mL (difference 6.1%; 95% CI -1.3 to 14.2%; p = 0.12) according to the FDA-defined snapshot algorithm. Both groups had similar proportions of subjects with virologic failure (2.8% switch, 1.4% no-switch). Discontinuations resulting from adverse events were infrequent (3% [9/291] switch, 2% [3/143] no-switch). Three switch participants (1%) discontinued due to renal adverse events (2 of the 3 before Week 48). Switch participants reported significant improvements in neuropsychiatric symptoms by as early as Week 4, and which were maintained through Week 96. CONCLUSIONS: E/C/F/TDF is safe and effective and reduces NNRTI-associated neuropsychiatric symptoms for virologically suppressed HIV-positive adults switching from an NNRTI plus FTC/TDF-based regimen.

OBJECTIVE: HIV/HCV-coinfected patients and hepatitis C virus (HCV) monoinfected subjects are thought to respond equally to direct-acting antiviral (DAA)-based therapy despite the lack of data derived from clinical trials. This study is aimed to evaluate the impact of HIV coinfection on the response to DAA-based treatment against HCV infection in the clinical practice. PATIENTS AND METHODS: In a prospective multicohort study, patients who initiated DAA-based therapy at the Infectious Disease Units of 33 hospitals throughout Spain were included. The primary efficacy outcome variables were the achievement of sustained virologic response 12 weeks after the scheduled end of therapy date (SVR12). RESULTS: A total of 908 individuals had reached the SVR12 evaluation time-point, 426 (46.9%) were HIV/HCV-coinfected, and 472 (52%) received interferon (IFN)-free therapy. In an intention-to-treat analysis, SVR12 rates in subjects with and without HIV-coinfection were 55.3% (94/170 patients) versus 67.3% (179/266 subjects; p = 0.012) for IFN-based treatment and 86.3% (221/256 subjects) versus 94.9% (205/216 patients, p = 0.002) for IFN-free regimens. Relapse after end-of-treatment response to IFN-free therapy was observed in 3/208 (1.4%) HCV-monoinfected subjects and 10/231 (4.4%) HIV/HCV-coinfected individuals (p = 0.075). In a multivariate analysis adjusted for age, sex, transmission route, body-mass index, HCV genotype, and cirrhosis, the absence of HIV-coinfection (adjusted odds ratio: 3.367; 95% confidence interval: 1.15-9.854; p = 0.027) was independently associated with SVR12 to IFN-free therapy. CONCLUSIONS: HIV-coinfection is associated with worse response to DAA-based therapy against HCV infection. In patients receiving IFN-free therapy, this fact seems to be mainly driven by a higher rate of relapses among HIV-coinfected subjects.

BACKGROUND: Antiretroviral therapy (ART) simplification to a single-tablet regimen can benefit HIV-1-infected, virologically suppressed, individuals on ART composed of multiple pills. OBJECTIVE: We assessed long-term efficacy and safety of switching to co-formulated elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (E/C/F/TDF) from multi-tablet ritonavir-boosted protease inhibitor (PI + RTV) plus F/TDF (TVD) regimens. METHODS: STRATEGY-PI was a 96-week, phase 3b, randomized (2:1), open-label, non-inferiority study examining the efficacy, safety, and tolerability of switching to E/C/F/TDF from PI + RTV + TVD regimens in virologically suppressed individuals (HIV-1 RNA <50 copies/mL). Participants were randomized to switch to E/C/F/TDF (switch group) or to continue their PI + RTV + TVD regimens (no-switch group). Eligibility criteria included no resistance to F/TDF or history of virologic failure, and estimated creatinine clearance ≥70 mL/min. RESULTS: At week 96, 87% (252/290) of switch and 70% (97/139) of no-switch participants maintained HIV-1 RNA <50 copies/mL (difference: 17%, 95% CI 8.7-26.0%, p < 0.001). Superiority of the switch to E/C/F/TDF vs. no-switch was due to a smaller proportion of both virologic failures (switch, 1% [3/290]; no-switch, 6% [8/139]) and discontinuations for non-virologic reasons (switch, 11% [31/290]; no-switch, 24% [33/139]). No treatment-emergent resistance was observed in switch subjects with virologic failure. Discontinuation rates from adverse events were 3% in both groups (9/293, switch; 4/140, no-switch). Switching from PI + RTV + TVD to E/C/F/TDF was associated with significant improvements in patient-reported outcomes related to gastrointestinal symptoms (nausea and bloating). CONCLUSION: E/C/F/TDF is a safe, effective long-term alternative to multi-tablet PI + RTV + TVD-based regimens in virologically suppressed, HIV-1-infected adults, and improves patient-reported gastrointestinal symptoms.

BACKGROUND: The combination antiretroviral therapy (cART) has dramatically improved the life expectancy of patients with HIV infection, but may lead to several long-term metabolic abnormalities. However, data about the frequency of metabolic syndrome (MS) in HIV-infected people vary considerably across different observational studies. METHODS: The prevalence of MS among HIV-infected patients was evaluated by a cross-sectional study conducted among subjects naive to cART or receiving the first antiretroviral regimen and referring to our Clinics from January 2015 to December 2015. The diagnosis of MS was made based on the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), and International Diabetes Federation (IDF) criteria. RESULTS: The study recruited 586 patients: 98 naive to cART and 488 under the first antiretroviral treatment. The prevalence of MS, according to NCEP-ATP III criteria, was significantly higher among treated patients than among naive ones (20.9% vs. 7.1%; p = 0.014). The most frequently reported components of MS among treated patients were high triglycerides (44.3%), low high-density lipoprotein cholesterol (41.1%), and hypertension (19.7%). On multivariate analysis, long duration of HIV infection, low nadir of CD4 lymphocytes, high body mass index, current use of one protease inhibitor, and long duration of cART were significantly associated with a higher risk of MS, while current use of one integrase inhibitor was significantly associated with a lower risk of MS. CONCLUSIONS: The non-negligible prevalence of MS among HIV-infected patients under cART requires a careful and periodic monitoring of its components, with particular attention to dyslipidemia and hypertension.

INTRODUCTION: The HIV Prevention Trials Network (HPTN) 052 trial demonstrated that early antiretroviral therapy (ART) prevented 93% of HIV transmission events in serodiscordant couples. Some linked infections were observed shortly after ART initiation or after virologic failure. OBJECTIVE: To evaluate factors associated with time to viral suppression and virologic failure in participants who initiated ART in HPTN 052. METHODS: 1566 participants who had a viral load (VL) > 400 copies/mL at enrollment were included in the analyses. This included 832 in the early ART arm (CD4 350-550 cells/mm at ART initiation) and 734 in the delayed ART arm (204 with a CD4 < 250 cells/mm at ART initiation; 530 with any CD4 at ART initiation). Viral suppression was defined as two consecutive VLs ≤ 400 copies/mL after ART initiation; virologic failure was defined as two consecutive VLs > 1000 copies/mL > 24 weeks after ART initiation. RESULTS: Overall, 93% of participants achieved viral suppression by 12 months. The annual incidence of virologic failure was 3.6%. Virologic outcomes were similar in the two study arms. Longer time to viral suppression was associated with younger age, higher VL at ART initiation, and region (Africa vs. Asia). Virologic failure was strongly associated with younger age, lower educational level, and lack of suppression by three months; lower VL and higher CD4 at ART initiation were also associated with virologic failure. CONCLUSIONS: Several clinical and demographic factors were identified that were associated with longer time to viral suppression and virologic failure. Recognition of these factors may help optimize ART for HIV treatment and prevention.

BACKGROUND: FTC/TAF was shown to be noninferior to FTC/TDF with advantages in markers of renal and bone safety. OBJECTIVE: To evaluate the efficacy and safety of switching to FTC/TAF from FTC/TDF by third agent (boosted protease inhibitor [PI] vs. unboosted third agent). METHODS: We conducted a 48-week subgroup analysis based on third agent from a randomized, double blind study in virologically suppressed adults on a FTC/TDF-containing regimen who switched to FTC/TAF vs. continued FTC/TDF while remaining on the same third agent. RESULTS: We randomized (1:1) 663 participants to either switch to FTC/TAF (N = 333) or continue FTC/TDF (N = 330), each with baseline third agent stratifying by class of third agent in the prior treatment regimen (boosted PI 46%, unboosted third agent 54%). At week 48, significant differences in renal biomarkers and bone mineral density were observed favoring FTC/TAF over FTC/TDF (p < 0.05 for all), with similar improvements in the FTC/TAF arm in those who received boosted PI vs. unboosted third agents. At week 48, virologic success rates were similar between treatment groups for those who received a boosted PI (FTC/TAF 92%, FTC/TDF 93%) and for those who received an unboosted third agent (97% vs. 93%). CONCLUSIONS: In virologically suppressed patients switching to FTC/TAF from FTC/TDF, high rates of virologic suppression were maintained, while renal and bone safety parameters improved, regardless of whether participants were receiving a boosted PI or an unboosted third agent. FTC/TAF offers safety advantages over FTC/TDF and can be an important option as an NRTI backbone given with a variety of third agents.

BACKGROUND: The HIV Care Cascade model can be used to measure how clinical services align with United Nations' (UN) HIV treatment targets. Previous models have highlighted sequential losses at each step of the Cascade with a significant proportion being not retained in care (NRIC). OBJECTIVE: We aimed to assess the feasibility of meeting the UN targets and assess factors associated with, and calculate the true proportion of those, NRIC. METHODS: All people living with HIV who were linked to our service, one of three specialist HIV care providers in Dublin Ireland, from its establishment in 1993 to 1 December 2014, were included in the cohort and were categorized as linked to care, retained in care (RIC), on antiretroviral therapy (on ART), virally suppressed (HIV RNA <40copies/ml), and NRIC. An analysis of those NRIC was performed to categorize their current status through direct/indirect contact. RESULTS: Of 1000 patients linked to care, 78.7% (n = 787) were RIC, of whom 91.5% (n = 720) were on ART, with 89.9% (n = 644) virally suppressed. Those RIC were more likely older (p = 0.006) and non-IVDU (p < 0.001). Of 213 (21.3%) NRIC, 56 (26.3%) emigrated, 27 (12.7%) transferred care, 15 (7.0%) stopped attending but were contactable, 38 (17.8%) died, and 77 (36.1%) were lost to follow-up. After revision, 10.5% of the cohort was confirmed as NRIC, with 6 of 15 defined as "stopped attending" re-linked to care following direct contact. CONCLUSIONS: Our HIV Care Cascade model demonstrates that the true numbers of patients NRIC may be significantly lower than previously estimated and once RIC, treatment goals approaching the United Nations Programme on HIV and AIDS targets are possible with 91.5% on treatment and almost 90% of those on treatment virally suppressed. That 40% reengaged following direct contact suggests benefit through regular monitoring and direct contact based on the HIV Care Cascade model.

BACKGROUND: Women's under-representation in HIV and cardiovascular disease (CVD) research suggests a need for novel strategies to ensure robust representation of women in HIV-associated CVD research. OBJECTIVE: To elicit perspectives on CVD research participation among a community-sample of women with or at risk for HIV, and to apply acquired insights toward the development of an evidence-based campaign empowering older women with HIV to participate in a large-scale CVD prevention trial. METHODS: In a community-based setting, we surveyed 40 women with or at risk for HIV about factors which might facilitate or impede engagement in CVD research. We applied insights derived from these surveys into the development of the Follow YOUR Heart campaign, educating women about HIV-associated CVD and empowering them to learn more about a multi-site HIV-associated CVD prevention trial: REPRIEVE. RESULTS: Endorsed best methods for learning about a CVD research study included peer-to-peer communication (54%), provider communication (46%) and video-based communication (39%). Top endorsed non-monetary reasons for participating in research related to gaining information (63%) and helping others (47%). Top endorsed reasons for not participating related to lack of knowledge about studies (29%) and lack of request to participate (29%). Based on survey results, the REPRIEVE Follow YOUR Heart campaign was developed. Interwoven campaign components (print materials, video, web presence) offer provider-based information/knowledge, peer-to-peer communication, and empowerment to learn more. Campaign components reflect women's self-identified motivations for research participation - education and altruism. CONCLUSIONS: Investigation of factors influencing women's participation in HIV-associated CVD research may be usefully applied to develop evidence-based strategies for enhancing women's enrollment in disease-specific large-scale trials. If proven efficacious, such strategies may enhance conduct of large-scale research studies across disciplines.

We developed and implemented a protocol to identify PLWH in a hospital setting. The aim of the current study was to report on our strategy to recruit hospitalized HIV patients into an intervention study, and to report on lessons learned for future studies. METHODS: Our protocol was developed based on experience of our research staff in recruiting HIV patients as well as clinical input from providers and administrators on delivering care in hospitalized settings. We identified hospitalized PLWH between 2010 and 2013 who were potentially eligible for an intervention study. Patients were identified by review of electronic medical records and clinician referral, followed by in-person screening to confirm eligibility. We examined factors related to identifying and enrolling hospitalized patients, and documented lessons learned. RESULTS: Key strategies included systematic medical record review followed by in-person screening, collaboration with staff, and flexibility in recruitment logistics. We identified 1801 PLWH hospitalized during the 3-year study period. Eighty-four percent (n = 1514) met the met the inclusion criteria based on medical record review. Of these, 48% (n = 733) were ineligible. Among eligible patients, 59% (n = 460) were enrolled. Only 3% (n = 23) of eligible patients declined; 84% (n = 321) were not enrolled because they were discharged before enrollment. Lessons learned included (1) needing to identify patients and deliver the intervention before hospital discharge, (2) limiting the complexity of the intervention, and (3) having research staff available on weekends and after hours. CONCLUSIONS: Targeted recruitment of hospitalized populations is a feasible and productive approach for finding and engaging PLWH who are newly diagnosed or out of routine care.

BACKGROUND: There is an international epidemic of hepatitis C virus (HCV) infection among HIV-infected men who have sex with men. We previously showed that adding telaprevir to pegylated interferon (IFN) and ribavirin (RBV) both shortened treatment and increased the cure rate of early HCV in these men. Whether shortening treatment of early HCV using IFN-free regimens would be similarly successful has not yet been demonstrated. METHODS: We performed a pilot study of treatment with sofosbuvir (SOF) + RBV for 12 weeks in early genotype 1 HCV infection in HIV-infected men. The primary endpoint was SVR 12. RESULTS: Twelve men were treated with 12 weeks SOF + RBV and 11 (92%) achieved SVR 12. Most (63%) were actively using recreational drugs, mostly methamphetamine. The one man who failed had laboratory results more characteristic of chronic than of early HCV infection. The overall safety profile was similar to that known for SOF + RBV. CONCLUSIONS: The success of this short-duration IFN-free treatment in early HCV infection is proof in principle that enhanced treatment responsiveness is an inherent characteristic of early HCV infection and not a function of IFN treatment itself. Future studies should now be done with more potent regimens to try to further shorten therapy. In the mean time, in clinical practice early HCV infection should be treated immediately after detection to take advantage of short-duration treatments, as well as to decrease further HCV transmission among HIV-infected MSM.

BACKGROUND: Nucleos(t)ide reverse transcriptase inhibitor (NRTI)-sparing regimens may potentially minimize antiretroviral (ART) toxicities, but demonstrate mixed efficacy and toxicity results. The impact of an integrase strand transfer inhibitor (INSTI) and protease inhibitor (PI) regimen on HIV viral dynamics and T cell kinetics remains underdescribed. OBJECTIVE: To compare the effect of raltegravir + ritonavir boosted lopinavir (RAL + LPV/r) to efavirenz/tenofovir disoproxil fumarate/emtricitabine (EFV/TDF/FTC) on HIV kinetics and T cell dynamics. METHODS: Fifty participants naïve to ART underwent HIV viral kinetic sampling evaluated using biexponential mixed effects modeling. A subset of 28 subjects (with complete viral suppression) underwent flow cytometry and evaluation of soluble markers of inflammation at weeks 0, 4, and 48 of ART. RESULTS: RAL + LPV/r compared to EFV/TDF/FTC resulted in a prolonged first phase viral decay rate (18 vs. 13 days p < 0.01). From weeks 0 to 4, RAL + LPV/r was associated with a trend toward greater decreases in activated CD4 T cells (-3.81 vs. -1.18 p = 0.09) and less decreases in activated effector memory CD4 T cells (-0.63 vs. -2.69 p-0.07). These trends did not persist to week 48. No differences were noted at any time point for soluble markers of immune activation. CONCLUSIONS: The prolonged first phase viral decay observed with RAL + LPV/r in persons starting ART did not result in differences in viral suppression at week 48. We also observed trends in declines in certain cellular markers of immune activation but it remains unclear if this could translate to long-term immunologic benefits in persons on an INSTI + PI.

BACKGROUND: Good efficacy and safety of raltegravir in person living with HIV was demonstrated in clinical trials over five years, but real-life data, particularly about quality of life (QoL), are lacking. QoL was evaluated over time in adult patients first treated or switched to regimens containing raltegravir in an observational cohort study. METHODS: Patient QoL was evaluated using the Fatigue Impact Scale (FIS) and the HIV Symptom Index (HSI). Data were collected at baseline and at 1, 3, 6, 12, 18, and 24 months. Baseline FIS and HSI subscores were compared with the scores at each visit using the paired Wilcoxon test. The impact of time, sociodemographic and medical variables upon patient-perceived fatigue and symptoms was also assessed using mixed multivariate models. RESULTS: From baseline, all FIS and HSI subscores improved significantly after one month of treatment. In addition, psychosocial FIS subscores and both the frequency of bothersome symptoms and HSI subscores improved significantly at each visit. Physical FIS subscores also improved significantly, except at month 18, whereas both cognitive and total FIS subscores improved only after 6 months and 24 months, respectively. In multivariate analysis, employment was independently associated over time with improved improvement in both FIS and HSI subscores. CONCLUSION: Patient QoL improved significantly over a 24-month period of treatment with a raltegravir-containing regimen. FIS and HSI are sensitive tools to measure the impact of new antiretroviral combinations on a patient's perception of QoL.

BACKGROUND: The objective of this study was to determine the impact of tenofovir or abacavir discontinuation on low-density lipoprotein (LDL) phenotype and lipoprotein-associated phospholipase A2 (Lp-PLA2) activity in HIV-infected patients treated with lopinavir/ritonavir plus 2 nucleos(t)ide reverse transcriptase inhibitors (NRTI). METHODS: Multicenter, open-label study. Patients were randomized to continue with lopinavir/ritonavir plus 2 NRTI (triple therapy) or to switch to lopinavir/ritonavir plus lamivudine (dual therapy). LDL phenotype (by gradient gel electrophoresis) and Lp-PLA2 (by 2-thio-PAF) were determined at baseline and week 48. RESULTS: Forty-four patients included (triple therapy n = 19, dual therapy n = 25): men 63.6%, age 41.5 years (25-61), Framingham score 4.9% (0.2-22). Tenofovir was part of the regimen in 28 (63.6%) patients. Dual therapy patients were younger (p = 0.013) and had lower baseline apolipoprotein A1 (p = 0.029). At week 48, there were no changes in standard lipid measurements, except ApoA1/Apo B, which increased in dual therapy (p = 0.038) with no differences between arms. At week 48, no change in LDL phenotype was found in either arm. No changes in total Lp-PLA2 activity or the relative distribution of LDL and HDL particles were found at week 48 in either arm. CONCLUSIONS: Discontinuing the third nucleos(t)ide, mainly tenofovir and abacavir, in a lopinavir/ritonavir-containing regimen was not associated with a deleterious effect on LDL phenotype nor in Lp-PLA2 activity.

OBJECTIVE: To evaluate the impact of Hepatitis B virus (HBV) coinfection on response to antiretroviral treatment in pregnant women with HIV. METHODS: Retrospective analysis of a large case series of pregnant women with HIV in Italy; outcome measures were CD4 changes, HIV viral load, and main pregnancy outcomes (preterm delivery, low birthweight, intrauterine growth restriction, mode of delivery, and major birth defects). RESULTS: Rate of HBV coinfection among 1462 pregnancies was 12.0%. Compared to the HBV-uninfected, HBV-coinfected women had a significantly lower median CD4 cell gain between first and third trimester (26.5 vs. 60 cells/mm, p = 0.034), with similar rate of undetectable (<50 copies/ml) HIV-RNA at third trimester (70.5% vs. 65.2%, p = 0.229), and no differences in all the main maternal and infant outcomes. A multivariable linear regression analysis identified four variables significantly and independently associated with a lower CD4 response in pregnancy: HBV coinfection (-35 cells/mm), being on antiretroviral treatment at conception (-59.7 cells/mm), AIDS status (-59.8 cells/mm) and higher first CD4 levels in pregnancy (-0.24 cells per unitary CD4 increase). CONCLUSIONS: HBV coinfection had no adverse influence on the main pregnancy outcomes or on HIV viral load suppression in late pregnancy but was associated with a significantly reduced CD4 response in pregnancy. This effect might have clinical relevance, particularly in women with advanced immune deterioration.

OBJECTIVES: To assess safety and efficacy of a switch to unboosted atazanavir (ATV) among HIV-infected adults receiving ATV/ritonavir (r) and tenofovir disoproxil fumarate (TDF). METHODS: HIV-infected adults with viral load (VL) <40 copies/mL at screening and <150 copies/mL consistently for ≥3 months while receiving a regimen including ATV/r and TDF were randomized to continue ATV/r 300/100 mg daily (control) or change to ATV 400 mg daily (switch), while maintaining their TDF backbone. The primary outcome was proportion of subjects without treatment failure (regimen switch or VL > 200 copies/mL twice consecutively) at 48 weeks. RESULTS: Fifty participants (46 male, median age 47 years) were randomized, 25 to each arm. At week 48, treatment success occurred in 76% in the control arm and 92% in the switch arm (ITT, p = 0.25). ATV trough levels at week 9 were higher in controls (median 438 ng/mL) than in the switch arm (median 124 ng/mL) (p = 0.003), as was total bilirubin at week 48 (median 38 μmol/L and 28 μmol/L, respectively; p = 0.02). Estimated glomerular filtration rate (eGFR) decreased in the control arm (p = 0.007), but did not change in the switch arm. At week 48, eGFR was higher in the switch arm (median 96 mL/min) than in the control arm (median 85 mL/min) (p = 0.035), but the arms were similar with respect to fasting glucose, C-reactive protein, and lipid parameters. CONCLUSIONS: Switching from ATV/r to unboosted ATV appears to be safe and effective in selected virologically suppressed patients receiving TDF-containing regimens, and may have favorable effects on bilirubin and renal function.

BACKGROUND: Antiretroviral therapy (ART) regimens for HIV infection are frequently changed. We conducted a systematic review of randomized trials (RCTs) on the benefits and harms of switching to tenofovir disoproxil fumarate (TDF)-based regimens in ART-experienced patients. METHODS: We included RCTs in HIV-infected adults comparing switching to a TDF-containing regimen with maintaining or switching to another regimen. We searched MEDLINE, EMBASE, CENTRAL, LILACS, SCI, and the WHO Global Health Library. We assessed bias with the Cochrane tool and synthesized data using random-effects meta-analyses and Peto's approach. For further analyses, we added data from a previous systematic review in treatment-naïve patients. RESULTS: 17 RCTs with 2210 patients were included. All but one study had a high risk of bias. There was no significant association of switching to TDF-based regimens with mortality, fractures, CD4-cell count, body fat, virological failure, LDL-, and HDL-cholesterol. TDF-based regimens decreased total cholesterol (mean difference -12.05 mg/dL; 95% CI -20.76 to -3.34), trigylcerides (-14.33 mg/dL; -23.73 to -4.93), and bone mineral density (BMD; hip: -2.46%; -3.9 to -1.03; lumbar spine -1.52%; -2.69 to -0.34). Effects on estimated glomerular filtration (eGFR) were inconsistent and depended on the measurement. Adding 22 RCTs from 8297 treatment-naïve patients gave consistent results with then significant reductions of LDL (-7.57 mg/dL; -10.37 to -4.78), HDL (-2.38 mg/dL; -3.83 to -0.93), and eGFR (-3.49 ml/min; -5.56 to -1.43). CONCLUSIONS: Switching to TDF-based regimens is associated with reductions of BMD and lipid levels and possibly lowered kidney function. The evidence is limited by the high risk of bias.

BACKGROUND: HIV-infected adults have increased fracture risk. OBJECTIVES: To generate pilot data comparing bone density, structure, and strength between HIV-infected adults with and without a prior fracture. METHODS: Adults with and without a prior fracture after their HIV diagnosis were matched 1:1 based on age, sex, race, and smoking history. Participants underwent dual-energy X-ray absorptiometry (DXA), trabecular bone score (TBS), hip structural analyses (HSA), vertebral fracture assessment (VFA), high-resolution peripheral quantitative tomography (HR-pQCT) and measurement of bone turnover markers. Results were compared between cases and controls, with differences expressed as percentages of control group values. RESULTS: 23 pairs were included. On DXA, cases had lower areal bone mineral density (aBMD) at the total hip (median difference in T-score -0.25, p = 0.04), but not the lumbar spine (median difference in T-score 0.10, p = 0.68). Cases had greater abnormalities in HSA and most HR-pQCT and HSA measures, by up to 15%. VFA revealed two subclinical fractures among cases but none among controls. TBS, CTX, and P1NP levels were similar between groups, with differences of 1.9% (p = 0.90), 9.7% (p = 0.55), and 10.0% (p = 0.24), respectively. For each parameter, we report the median and interquartile range for the absolute and relative difference between cases and controls, the correlation between cases and controls, and our recruitment rates, to inform the design of future studies. CONCLUSIONS: These pilot data suggest potential differences in bone structure, estimated bone strength, and asymptomatic vertebral fractures among HIV-infected adults with and without fracture, warranting further study as markers of fracture risk in HIV.

BACKGROUND: There is no known reason to suspect an adverse drug interaction between dolutegravir-based antiretroviral therapy and sofosbuvir, simeprevir, or ledipasvir. There is a paucity of clinical data for this combination. METHODS: Prospective, open-label study of patients with HIV well controlled on dolutegravir, abacavir, and lamivudine, who were co-infected with HCV genotype 1, and required therapy with simeprevir plus sofosbuvir or sofosbuvir/ledipasvir single-tablet regimen (STR) for 12 weeks. The two primary endpoints were percentage of patients achieving sustained virologic response (SVR) at 12 weeks post-treatment and percentage of patients with a HIV-1 viral load <50 copies/ml at end of the combination therapy. RESULTS: Twenty-eight subjects were enrolled from August 2014 to September 2015. Thirteen patients were treated with simprevir plus sofosbuvir, and 15 subjects were treated with sofosbuvir/ledipasvir. 23 genotype 1a, and 5 genotype 1b were included. Nineteen were treatment naïve, and 2 patients had compensated cirrhosis. The mean age was 59 years (95% CI 58.21-59.78 years). The mean age was 59 years (95% CI: 58.21-59.78 years), and 25 patients were black. Out of the 28 patients who completed this study, SVR 12 was achieved in 27 of 28 patients (96%, 95% CI 89.6-100.0%), and all patients had an HIV virus load <50 copies/ml at week 12 of therapy, for an intent-to-treat rate of 100%. No patients ended therapy secondary to adverse events. CONCLUSION: Our study suggests a good safety and efficacy for the combination of a dolutegravir, abacavir, and lamivudine with sofosbuvir-based DAA therapy.

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is a component of many combinations of antiretroviral treatment (ART) regimens. Although potent and generally well tolerated, TDF may cause renal and bone toxicity. The magnitude of off-target side effects is proposed to be related to tenofovir plasma concentrations, which are affected by food and drug-drug interactions with concomitant antiretrovirals. OBJECTIVE: To perform a systematic literature review and qualitatively report on renal and bone safety outcomes associated with efavirenz (EFV), emtricitabine (FTC), and TDF (EFV+FTC+TDF) ART. METHODS: Embase and PubMed databases were searched for randomized clinical trials and observational cohort studies reporting on HIV treatment with EFV+FTC+TDF. Relevant articles were hand-searched for renal (Grade 3-4 serum creatinine/estimated glomerular filtration rate elevations, renal adverse events [AEs], discontinuation due to renal AEs, and urinary biomarkers) and bone outcomes (bone mineral density [BMD] reductions, bone turnover markers, and fracture), and results compiled qualitatively. RESULTS: Of 337 retrieved articles, 29 reporting renal and 11 reporting bone outcomes met the review criteria. EFV+FTC+TDF was associated with a low frequency of renal AEs and treatment discontinuations due to renal AEs. Renal AEs were more frequent when TDF was taken with protease inhibitor (PI)- or cobicistat-containing ART. EFV+FTC+TDF was associated with reduced BMD and increased bone turnover markers, but BMD reductions were less than with PI-containing ART. No treatment-related bone fractures were identified. CONCLUSIONS: EFV+FTC+TDF appeared to have a more favorable renal safety profile than TDF administered with a PI or cobicistat. BMD decreased with EFV+FTC+TDF, but no treatment-related fractures were identified.
