RESUMO

BACKGROUND: People with HIV (PWH) are at elevated risk for suicidal ideation (SI), yet few studies have examined how substance use, clinical and sociodemographic factors are associated with SI among PWH. METHOD: We used substance use (Tobacco, Alcohol, Prescription Medication, and Other Substance Use [TAPS]) and depression (PHQ-9) data from computerized screening of adult PWH in primary care clinics in Northern California, combined with health record data on psychiatric diagnoses, HIV diagnosis, treatment, and control (HIV RNA, CD4), insurance, and neighborhood deprivation index (NDI) to examine factors associated with SI (PHQ-9 item 9 score > 0). Adjusted odds ratios (aOR) for SI were obtained from logistic regression models. RESULTS: Among 2829 PWH screened (92 % male; 56 % white; mean (SD) age of 54 (13) years; 220 (8 %) reported SI. Compared with no problematic use, SI was higher among those reporting one (aOR = 1.65, 95 % CI = 1.17, 2.33), two (aOR = 2.23, 95 % CI = 1.42, 3.49), or ≥ 3 substances (aOR = 4.49, 95 % CI = 2.41, 8.39). SI risk was higher for those with stimulant use (aOR = 3.55, 95 % CI = 2.25, 5.59), depression (aOR = 4.18, 95 % CI = 3.04, 5.74), and anxiety diagnoses (aOR = 1.67, 95 % CI = 1.19, 2.34), or Medicaid (aOR = 2.11, 95%CI = 1.24, 3.60) compared with commercial/other insurance. SI was not associated with HIV-related measures or NDI. LIMITATIONS: SI was assessed with a single PHQ-9 item. Simultaneous SI and exposure data collection restricts the ability to establish substance use as a risk factor. CONCLUSIONS: HIV care providers should consider multiple substance use, stimulant use, depression or anxiety, and public insurance as risk factors for SI and provide interventions when needed.

RESUMO

BACKGROUND: Management of hypertension, dyslipidemia, diabetes and other modifiable factors may mitigate the cardiovascular disease (CVD) risk in people with human immunodeficiency virus (HIV, PWH) compared with people without HIV (PWoH). METHODS: This was a retrospective cohort study of 8285 PWH and 170 517 PWoH from an integrated health system. Risk factor control was measured using a novel disease management index (DMI) accounting for amount/duration above treatment goals (0% to 100% [perfect control]), including 2 DMIs for hypertension (diastolic and systolic blood pressure), 3 for dyslipidemia (low-density lipoprotein, total cholesterol, triglycerides), and 1 for diabetes (HbA1c). CVD risk by HIV status was evaluated overall and in subgroups defined by DMIs, smoking, alcohol use, and overweight/obesity in adjusted Cox proportional hazards models. RESULTS: PWH and PWoH had similar DMIs (80%-100%) except for triglycerides (worse for PWH) and HbA1c (better for PWH). In adjusted models, PWH had an elevated risk of CVD compared with PWoH (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.07-1.31). This association was attenuated in subgroups with controlled dyslipidemia and diabetes but remained elevated for PWH with controlled hypertension or higher total cholesterol. The strongest HIV status association with CVD was seen in the subgroup with frequent unhealthy alcohol use (HR, 2.13; 95% CI, 1.04-4.34). CONCLUSIONS: Control of dyslipidemia and diabetes, but not hypertension, attenuated the HIV status association with CVD. The strong association of HIV and CVD with frequent unhealthy alcohol use suggests enhanced screening and treatment of alcohol problems in PWH is warranted.

RESUMO

We characterized polysubstance use burden and associations with mental health problems across demographic subgroups of PWH. In 2018-2020, as part of a primary care-based intervention study, PWH in care at three medical centers in Kaiser Permanente Northern California were screened for depression (PHQ-9≥10), anxiety (GAD-2≥3), and substance use (Tobacco, Alcohol, Prescription medication, and other Substance use [TAPS]≥1 per substance). We used Poisson regression to estimate prevalence ratios (PRs) comparing polysubstance use prevalence (TAPS≥1 for ≥2 substances) between PWH with positive screens for depression or anxiety vs. neither, among all PWH, and stratified by race/ethnicity and age (restricted to men), adjusting for sociodemographics, CD4, and HIV load. Screened PWH (N = 2865) included 92% men, 56% White, 19% Black, and 15% Hispanic PWH, with a median age of 55 years. Overall, polysubstance use prevalence was 26.4% (95% CI 24.9%-28.1%). PWH with depression or anxiety (n = 515) had an adjusted polysubstance use PR of 1.26 (1.09-1.46) vs. PWH with neither (n = 2350). Adjusted PRs were 1.47 (1.11-1.96), 1.07 (0.74-1.54), and 1.10 (0.85-1.41) among Black, Hispanic, and White men, respectively. Adjusted PRs did not differ by age group. Interventions should consider jointly addressing mental health and substance use problems and potential drivers, e.g. stigma or socioeconomic factors.

RESUMO

BACKGROUND: Mental health and substance use disorders disproportionately affect people with HIV (PWH), and may have been exacerbated during COVID-19. The Promoting Access to Care Engagement (PACE) trial was designed to assess the effectiveness of electronic screening for mental health and substance use in HIV primary care and enrolled PWH from October 2018 to July 2020. Our objective here was to compare screening rates and results for PWH before (October 2018 - February 2020) and early in the COVID-19 pandemic (March-July 2020). METHODS: Adult (≥ 18 years) PWH from 3 large HIV primary care clinics in a US-based integrated healthcare system were offered electronic screening online or via in-clinic tablet computer every 6 months. Screening completion and results (for depression, suicidal ideation, anxiety, and substance use) were analyzed using logistic regression with generalized estimating equations to estimate prevalence ratios (PR) before and after the start of the regional COVID-19 shelter-in-place orders on March 17, 2020. Models adjusted for demographics (age, sex, race/ethnicity), HIV risk factors (men who have sex with men, injection drug use, heterosexual, other), medical center, and modality of screening completion (online or tablet). We conducted qualitative interviews with providers participating in the intervention to evaluate how the pandemic impacted patient care. RESULTS: Of 8,954 eligible visits, 3,904 completed screenings (420 during COVID, 3,484 pre-COVID), with lower overall completion rates during COVID (38% vs. 44%). Patients completing screening during COVID were more likely to be White (63% vs. 55%), male (94% vs. 90%), and MSM (80% vs., 75%). Adjusted PRs comparing COVID and pre-COVID (reference) were 0.70 (95% CI), 0.92 (95% CI), and 0.54 (95% CI) for tobacco use, any substance use, and suicidal ideation, respectively. No significant differences were found by era for depression, anxiety, alcohol, or cannabis use. These results were in contrast to provider-reported impressions of increases in substance use and mental health symptoms. CONCLUSION: Findings suggest PWH had modest declines in screening rates early in the COVID-19 pandemic which may have been affected by the shift to telemedicine. There was no evidence that mental health problems and substance use increased for PWH in primary care.

RESUMO

Outcomes of PWH with unhealthy alcohol use, such as alcohol use reduction or progression to AUD, are not well-known and may differ by baseline patterns of unhealthy alcohol use. Among 1299 PWH screening positive for NIAAA-defined unhealthy alcohol use in Kaiser Permanente Northern California, 2013-2017, we compared 2-year probabilities of reduction to low-risk/no alcohol use and rates of new AUD diagnoses by baseline use patterns, categorized as exceeding: only daily limits (72% of included PWH), only weekly limits (17%), or both (11%), based on NIAAA recommendations. Overall, 73.2% (95% CI 70.5-75.9%) of re-screened PWH reduced to low-risk/no alcohol use over 2 years, and there were 3.1 (95% CI 2.5-3.8%) new AUD diagnoses per 100 person-years. Compared with PWH only exceeding daily limits at baseline, those only exceeding weekly limits and those exceeding both limits were less likely to reduce and likelier to be diagnosed with AUD during follow-up. PWH exceeding weekly drinking limits, with or without exceeding daily limits, may have a potential need for targeted interventions to address unhealthy alcohol use.

RESUMO

INTRODUCTION: The CUSTOMIZE hybrid III implementation-effectiveness study evaluated implementation of once-monthly long-acting (LA) cabotegravir + rilpivirine in diverse US healthcare settings. Here, we report patient participant perspectives after 12 months in CUSTOMIZE. METHODS: CUSTOMIZE was a phase IIIb, 12-month study conducted from July 2019 to October 2020 at eight diverse US HIV clinics that enrolled virologically suppressed people living with HIV-1 (PLHIV) on a stable oral regimen to receive monthly cabotegravir + rilpivirine LA injections after a 1-month oral lead-in. Participants were administered quantitative surveys before injections at months 1 (baseline), 4 and 12. A randomly selected subset of participants was interviewed at baseline and month 12. Data collection at month 12 was completed by October 2020 (during the COVID-19 pandemic). RESULTS: At baseline, 109 and 34 participants completed surveys and interviews, respectively; 87% were male; 35% were Black or African American. All participants who remained in the study at month 12 (n = 102) maintained HIV-1 RNA <50 copies/ml; two participants withdrew due to injection-related reasons. Mean total scores measuring acceptability and appropriateness of cabotegravir + rilpivirine LA were high at baseline (4.5-4.6 out of 5) and month 12 (4.7-4.9). At month 12, 74% of participants reported nothing interfered with receiving LA injections; injection pain or soreness was the most common concern (15%). Time spent in the clinic and coming to the clinic for monthly injections was very or extremely acceptable after 12 months for most participants (93% and 87%, respectively), with 64% reporting having spent ≤30 minutes in the clinic for injection visits. At month 12, 92% of participants preferred LA injections to daily oral tablets (3%); 97% plan to continue LA treatment going forward. In month 12 interviews, 24 (77%) of 31 participants reported the COVID-19 pandemic did not impact their ability to receive treatment. CONCLUSIONS: Once-monthly cabotegravir + rilpivirine LA was highly acceptable among PLHIV who were virologically suppressed on a stable antiretroviral regimen and interested in trying LA therapy, with few participants reporting challenges receiving LA injections. Implementation data from CUSTOMIZE suggest that monthly LA injections provide a convenient and appealing treatment option for PLHIV.

RESUMO

INTRODUCTION: CUSTOMIZE evaluated the implementation of long-acting (LA) cabotegravir + rilpivirine, a novel healthcare provider-administered injectable antiretroviral therapy regimen, in diverse US healthcare settings. Findings from staff-study participants (SSPs) through 12 months of implementation are reported. METHODS: CUSTOMIZE was a phase IIIb, 12-month, single-arm, hybrid III implementation-effectiveness study conducted from July 2019 to October 2020 at eight US clinics of five clinic types: private practice (n = 2), federally qualified health centre (n = 2), university (n = 2), AIDS Healthcare Foundation (n = 2) and health maintenance organization (n = 1). Eligible patient participants received monthly cabotegravir + rilpivirine LA injections after a 1-month oral lead-in. At baseline, month 4 and month 12, SSPs (n = 3 each per clinic), including physicians, nurses or injectors, and administrators, completed quantitative surveys and semi-structured interviews to assess implementation outcomes (acceptability, appropriateness and feasibility of intervention measures), programme sustainability and SSP perceptions of, attitudes towards, and expectations for cabotegravir + rilpivirine LA. Month 12 data collection occurred during the COVID-19 pandemic. RESULTS: In surveys, SSPs reported high mean total scores for acceptability, appropriateness and feasibility of cabotegravir + rilpivirine LA implementation at baseline (4.43, 4.52 and 4.38 of 5, respectively) and month 12 (4.45, 4.61 and 4.46 of 5, respectively), regardless of clinic type. At month 12, SSPs were positive about the implementation sustainability (mean Program Sustainability Assessment Tool score, 5.83 out of 7). At baseline, SSPs' top concern was patients' ability to maintain monthly appointments (81%); at month 12, 39% had this concern. The proportion of SSPs reporting patient injection pain or soreness as a barrier was consistent at month 12 versus baseline (48% vs. 46%). Most (78%) SSPs reported optimal implementation of cabotegravir + rilpivirine LA in their clinics was achieved in 1-3 months. In interviews, SSP-reported strategies for successful implementation included teamwork, using a web-based treatment planner and having a designated person to track appointment scheduling. In month 12 interviews, SSP-reported structural changes needed for implementation included changing clinic hours and purchasing refrigerators. CONCLUSIONS: In CUSTOMIZE, cabotegravir + rilpivirine LA was successfully implemented across a range of US healthcare settings. Barriers were mitigated with minor process adjustments.

RESUMO

OBJECTIVE: To compare dementia incidence and prevalence after age 50 years by HIV status. DESIGN: Observational cohort, 2000-2016. METHODS: People with HIV (PWH) on antiretroviral therapy (ART) and demographically similar people without HIV (PWoH), all aged 50 years and older, were identified from Kaiser Permanente healthcare systems in Northern California, Southern California, and Mid-Atlantic States (Maryland, Virginia, Washington DC). Dementia diagnoses were obtained from electronic health records. Incidence and prevalence of dementia, overall and by time period (i.e. 2000-2002, 2003-2004, …, 2015-2016), were calculated using Poisson regression. Trends were examined using Joinpoint regression. Rate ratios were used to compare dementia by HIV status with adjustment for sociodemographics, substance use, and clinical factors. RESULTS: The study included 13 296 PWH and 155 354 PWoH (at baseline: for both, mean age = 54 years, 89% men; for PWH, 80% with HIV RNA <200 copies/ml). From 2000 to 2016, overall incidence of dementia was higher among PWH [adjusted incidence rate ratio (aIRR) = 1.80, 95% confidence interval (CI) = 1.60-2.04]. Dementia incidence decreased among both PWH and PWoH (-8.0 and -3.1% per period, respectively) but remained higher among PWH in the most recent time period, 2015-2016 (aIRR = 1.58, 95% CI = 1.18-2.12). The overall prevalence of dementia from 2000 to 2016 was higher among PWH [adjusted prevalence ratio (aPR) = 1.86, 95% CI = 1.70-2.04] and was also higher among PWH in 2015-2016 (aPR = 1.75, 95% CI = 1.56-1.97). CONCLUSION: Reductions in dementia incidence are encouraging and may reflect ART improvement, but PWH are still more likely to have dementia than PWoH. Monitoring the burden of dementia among PWH is important as this population ages.

RESUMO

ABSTRACT: We implemented self-collected gonorrhea/chlamydia testing in 17 medical centers in California serving men who have sex with men living with HIV. From 2012 to 2018, gonorrhea/chlamydia testing increased from 45.2% to 63.4%. Among those tested, rectal testing increased from 42.0% to 77.3%; pharyngeal testing increased from 31.0% to 79.9% (all, Ptrend < 0.0001).

RESUMO

BACKGROUND: Unhealthy alcohol use among persons living with HIV (PLWH) is linked to significant morbidity, and use of alcohol services may differ by HIV status. Our objective was to compare unhealthy alcohol use screening and treatment by HIV status in primary care. METHODS: Cohort study of adult (≥18 years) PLWH and HIV-uninfected participants frequency matched 20:1 to PLWH by age, sex, and race/ethnicity who were enrolled in a large integrated healthcare system in the United States, with information ascertained from an electronic health record. Outcomes included unhealthy alcohol screening, prevalence, provider-delivered brief interventions, and addiction specialty care visits. Other predictors included age, sex, race/ethnicity, neighborhood deprivation index, depression, smoking, substance use disorders, Charlson comorbidity index, prior outpatient visits, insurance type, and medical facility. Cox proportional hazards models were used to compute hazard ratios (HR) for the outcomes of time to unhealthy alcohol use screening and time to first addiction specialty visit. Poisson regression with robust standard errors was used to compute prevalence ratios (PR) for other outcomes. RESULTS: 11,235 PLWH and 227,320 HIV-uninfected participants were included. By 4.5 years after baseline, most participants were screened for unhealthy alcohol use (85% of PLWH and 93% of HIV-uninfected), but with a lower rate among PLWH (adjusted HR 0.84, 95% CI 0.82 to 0.85). PLWH were less likely, compared with HIV-uninfected participants, to report unhealthy drinking among those screened (adjusted PR 0.74, 95% CI 0.69 to 0.79), and among those who screened positive, less likely to receive brief interventions (adjusted PR 0.82, 95% CI 0.75 to 0.90), but more likely (adjusted HR 1.7, 95% CI 1.2 to 2.4) to have an addiction specialty visit within 1 year. CONCLUSIONS: Unhealthy alcohol use was lower in PLWH, but the treatment approach by HIV status differed. PLWH reporting unhealthy alcohol use received less brief interventions and more addiction specialty care than HIV-uninfected participants.

RESUMO

BACKGROUND: In the primary week-48 analyses of two phase 3 studies, coformulated bictegravir, emtricitabine, and tenofovir alafenamide was non-inferior to a dolutegravir-containing regimen in treatment-naive people with HIV. We report week-144 efficacy and safety results from these studies. METHODS: We did two double-blind, active-controlled studies (now in open-label extension phase). Study 1 randomly assigned (1:1) HLA-B*5701-negative adults without hepatitis B virus co-infection to receive coformulated bictegravir 50 mg, emtricitabine 200 mg, and tenofovir alafenamide 25 mg, or coformulated dolutegravir 50 mg, abacavir 600 mg, and lamivudine 300 mg once daily. Study 2 randomly assigned (1:1) adults to bictegravir, emtricitabine, and tenofovir alafenamide, or dolutegravir 50 mg given with coformulated emtricitabine 200 mg and tenofovir alafenamide 25 mg. We previously reported non-inferiority at the primary endpoint. Here, we report the week-144 secondary outcome of proportion of participants with plasma HIV-1 RNA less than 50 copies per mL at week 144, by US Food and Drug Administration Snapshot algorithm, analysed in the same manner. These studies were registered with ClinicalTrials.gov, NCT02607930 and NCT02607956. FINDINGS: 629 participants were randomly assigned and treated in study 1 (314 to bictegravir, emtricitabine, and tenofovir alafenamide, and 315 to dolutegravir, abacavir, and lamivudine) and 645 in study 2 (327 to bictegravir, emtricitabine, and tenofovir alafenamide, 325 to dolutegravir, emtricitabine, tenofovir alafenamide). At week 144, bictegravir, emtricitabine, and tenofovir alafenamide was non-inferior to both dolutegravir-containing regimens for efficacy. In study 1, 256 (82%) of 314 participants had plasma HIV-1 RNA less than 50 copies per mL in the bictegravir, emtricitabine, and tenofovir alafenamide group and 265 (84%) of 315 in the dolutegravir, abacavir, and lamivudine group (difference -2·6%, 95% CI -8·5 to 3·4). In study 2, 262 (82%) of 320 participants had plasma HIV-1 RNA less than 50 copies per mL in the bictegravir, emtricitabine, and tenofovir alafenamide group and 273 (84%) of 325 in the dolutegravir, emtricitabine, and tenofovir alafenamide group (difference -1·9%, -7·8 to 3·9). In both studies, no participant had treatment-emergent resistance to study drugs up to week 144. All treatment regimens were well tolerated with additional exposure. Adverse events that led to study drug discontinuation were reported for no participants in the bictegravir, emtricitabine, and tenofovir alafenamide group versus five (2%) of 315 in the dolutegravir, abacavir, and lamivudine group (study 1), and six (2%) of 320 in the bictegravir, emtricitabine, and tenofovir alafenamide versus six (2%) of 325 in the dolutegravir, emtricitabine, and tenofovir alafenamide group (study 2). In study 1, statistically significant differences were observed in median changes from baseline in fasting total cholesterol (14 mg/dL vs 10 mg/dL; p=0·034), direct LDL (21 mg/dL vs 14 mg/dL; p=0·004), and total cholesterol to HDL ratio (-0·1 vs -0·3; p=0·007) at week 144; no differences were observed between groups in study 2. Weight gain was seen across all treatment groups in both studies, with no differences in median changes from baseline in weight at week 144 for either study. INTERPRETATION: These long-term data support the use of bictegravir, emtricitabine, and tenofovir alafenamide as a safe, well tolerated, and durable treatment for people with HIV, with no emergent resistance.

RESUMO

BACKGROUND: Substance use disorders (SUDs) and psychiatric disorders are common among people with HIV (PWH) and lead to poor outcomes. Yet these conditions often go unrecognized and untreated in primary care. METHODS: The Promoting Access to Care Engagement (PACE) trial currently in process examines the impact of self-administered electronic screening for SUD risk, depression and anxiety in three large Kaiser Permanente Northern California primary care clinics serving over 5000 PWH. Screening uses validated measures (Tobacco, Alcohol, Prescription medication, and other Substance use [TAPS]; and the Adult Outcomes Questionnaire [AOQ], which includes the Patient Health Questionnaire [PHQ-9] and Generalized Anxiety Disorder [GAD-2]) delivered via three modalities (secure messaging, tablets in waiting rooms, and desktop computers in exam rooms). Results are integrated automatically into the electronic health record. Based on screening results and physician referrals, behavioral health specialists embedded in primary care initiate motivational interviewing- and cognitive behavioral therapy-based brief treatment and link patients to addiction and psychiatry clinics as needed. Analyses examine implementation (screening and treatment rates) and effectiveness (SUD, depression and anxiety symptoms; HIV viral control) outcomes using a stepped-wedge design, with a 12-month intervention phase implemented sequentially in the clinics, and a 24-month usual care period prior to implementation in each clinic functioning as sequential observational phases for comparison. We also evaluate screening and treatment costs and implementation barriers and facilitators. DISCUSSION: The study examines innovative, technology-facilitated strategies for improving assessment and treatment in primary care. Results may help to inform substance use, mental health, and HIV services. TRIAL REGISTRATION: NCT03217058.

RESUMO

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.

RESUMO

OBJECTIVES: To evaluate the safety and efficacy of the novel tenofovir prodrug, tenofovir alafenamide (TAF), as part of the first protease inhibitor-based single-tablet regimen (STR) for initial treatment of HIV-1 infection. METHODS: Antiretroviral therapy (ART)-naive adults with estimated glomerular filtration rate ≥ 70 mL/min were randomized 2:1 to receive the darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) STR (TAF: N = 103) or darunavir + cobicistat + emtricitabine/tenofovir disoproxil fumarate (TDF: N = 50) once daily with matched placebos for 48 weeks. RESULTS: At week 24, viral suppression (HIV-1 RNA <50 copies/mL) rates were similar (TAF 74.8% vs. TDF 74.0%). At week 48, rates were TAF 76.7% vs. TDF 84.0%; the difference was driven by higher rate of discontinuations in TAF (6.8%) vs. TDF (2%). Among those with virologic failure, none developed resistance. Most adverse events were of mild/moderate severity. The mean change in serum creatinine from baseline at week 48 was 0.06 mg/dL (95% confidence interval: 0.04 to 0.08) for TAF vs. 0.09 mg/dL (95% confidence interval: 0.05 to 0.14) for TDF (P = 0.053). The % change in retinol binding protein/Cr ratio was +9 (TAF) vs. +54 (TDF), P = 0.003; the % change in urine ß-2 microglobulin/Cr ratio was -42.0 (TAF) vs. +2.3 (TDF), P = 0.002. The % change in hip bone mineral density (BMD) was -0.84 (TAF) vs. -3.82 (TDF), P < 0.001 and in spine BMD was -1.57 (TAF) vs. -3.62 (TDF), P = 0.003. There were no fractures in either group. CONCLUSIONS: The TAF arm had significantly improved renal and bone safety parameters: less proteinuria and less change in hip and spine BMD, consistent with results from a similarly designed study of the elvitegravir/C/F/TAF STR. This D/C/F/TAF STR offers a promising option for initial HIV treatment, with the high barrier to resistance of darunavir, and the potential for improved long-term renal and bone safety with TAF.

RESUMO

INTRODUCTION: Switch to Stribild (STB) was non-inferior to continuation of a non-nucleoside reverse transcriptase inhibitor (NNRTI) with emtricitabine and tenofovir DF (FTC/TDF) at week 48 in virologically suppressed HIV adults (1). We report the Week 48 efficacy and safety of STB versus nevirapine (NVP) or rilpivirine (RPV) with FTC/TDF in suppressed subjects. MATERIALS AND METHODS: Virologically suppressed subjects on an NNRTI with FTC/TDF regimens for ≥6 months were randomized (2:1) to switch to STB versus continue their NNRTI regimen. Eligibility criteria included no documented resistance to FTC and TDF, no history of virologic failure and eGFR ≥70 mL/min. The primary endpoint was the proportion of subjects in the modified ITT population who maintained HIV-1 RNA <50 copies(c)/mL at Week 48 by FDA snapshot algorithm (12% non-inferiority margin). Subgroup analysis by non-EFV NNRTI use (NVP [74]; RPV [19]; etravirine [3]) at screening was pre-specified. RESULTS: The mITT population included 433 subjects who were randomized and treated. In the non-EFV NNRTI subgroup, 59 switched to STB; 37 continued a non-EFV NNRTI (27 NVP, 10 RPV) with FTC/TDF. At week 48, 97% STB versus 95% non-EFV NNRTI maintained HIV-1 RNA <50 c/mL. No emergent resistance was detected in either group. No difference in median increases from baseline in CD4 count at week 48 (cells/µL): 25 STB versus 55 non-EFV NNRTI (p=0.78). No discontinuation due to adverse events; no cases of proximal renal tubulopathy. As expected, there were no significant changes in the frequency of neuropsychiatric symptoms (i.e. anxiety, insomnia, dizziness, vivid dreams, weird/intense dreams, and nightmares) reported on the HIV Symptom Index at week 48 compared to baseline after switching to STB. There was a greater but non-progressive decrease from baseline in eGFR in the STB versus non-EFV NNRTI group; median changes (mL/min) at week 48: -9.1 versus -1.4. Switch to STB was associated with a higher treatment ease (convenience, flexibility, demand, lifestyle, understanding) score (range: -15 to 15) at week 4 (median: 14 vs 11; p=0.047) and week 24 (median: 14 vs 12.5; p=0.038). CONCLUSIONS: In this small group of virologically suppressed subjects, switch to STB vs continuation of NVP or RPV with FTC/TDF was safe, well-tolerated, and associated with a high rate of virologic suppression at week 48. There was more treatment ease with STB use.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of antiretroviral simplification from a ritonavir-boosted protease inhibitor-based regimen [protease inhibitor+RTV+two nucleos(t)ide reverse transcriptase inhibitors (NRTIs); ≥6 months of exposure prior to study entry with no prior treatment failure] to the single-tablet regimen (STR) rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) in virologically suppressed, HIV-1-infected participants. DESIGN: Phase 3b, randomized, open-label, international, 48-week switch study. METHODS: Participants were randomized 2 : 1 to switch to RPV/FTC/TDF immediately or stay on their baseline protease inhibitor+RTV+2NRTIs regimen with a delayed switch to RPV/FTC/TDF at week 24. The primary endpoint was noninferiority (12% margin) of RPV/FTC/TDF compared with protease inhibitor+RTV+ two NRTIs in maintaining plasma HIV-1 RNA less than 50 copies/ml at week 24 by Snapshot analysis. RESULTS: A total of 476 participants were randomized and received at least one dose of study drug. Demographics and baseline characteristics were similar between arms. The primary objective of noninferiority at week 24 was met: HIV-1 RNA less than 50 copies/ml by Snapshot analysis, 93.7% of RPV/FTC/TDF versus 89.9% of protease inhibitor+RTV+ two NRTIs (difference 3.8%, 95% confidence interval -1.6 to 9.1%). Through week 48, 89.3% of participants in the immediate switch group maintained virologic suppression. High rates of suppression were maintained with RPV/FTC/TDF regardless of participant's pre-antiretroviral HIV-1 RNA level. Overall development of resistance mutations after switching to RPV/FTC/TDF was low. Decreases in total cholesterol, low-density lipoprotein (LDL), and triglycerides were significantly greater among RPV/FTC/TDF recipients than those in the protease inhibitor+RTV+ two NRTIs group. CONCLUSION: Switching to the STR RPV/FTC/TDF from an RTV-boosted protease inhibitor regimen in virologically suppressed, HIV-1-infected participants maintained virologic suppression with a low risk of virologic failure, while improving total cholesterol, LDL, and triglycerides.

RESUMO

BACKGROUND: Women and men have diverse responses to many infectious diseases. These differences are amplified following menopause. However, despite extensive information regarding the effects of sex hormones on immune cells, our knowledge is limited regarding the effects of sex and gender on the function of the mucosal immune system. Sex differences also manifest in the prevalence of gut associated inflammatory and autoimmune disorders, including Crohn's disease, ulcerative colitis and Celiac disease. It is thus hypothesized that a baseline sex-associated difference in immune activation may predispose women to inflammation-associated disease. METHODS: Peripheral blood samples and small intestinal biopsies were obtained from 34 healthy men and women. Immunophenotypic analysis of isolated lymphocytes was performed by flow cytometry. Oligonucleotide analysis was used to study the transcriptional profile in the gut mucosal microenvironment while real-time PCR analysis was utilized to identify differential gene expression in isolated CD4+ T cells. Transcriptional analysis was confirmed by protein expression levels for genes of interest using fluorescent immunohistochemistry. Data was analyzed using the GraphPad software package. RESULTS: Women had higher levels of immune activation and inflammation-associated gene expression in gut mucosal samples. CD4+ and CD8+ T cells had a significantly higher level of immune activation-associated phenotype in peripheral blood as well as in gut associated lymphoid tissue along with higher levels of proliferating T cells. CD4+ T cells that showed upregulation of IL1ß as well as the TH17 pathway-associated genes contributed a large part of the inflammatory profile. CONCLUSION: In this study, we demonstrated an upregulation in gene expression related to immune function in the gut microenvironment of women compared to men, in the absence of disease or pathology. Upon closer investigation, CD4+ T cell activation levels were higher in the LPLs in women than in men. Sex differences in the mucosal immune system may predispose women to inflammation-associated diseases that are exacerbated following menopause. Our study highlights the need for more detailed analysis of the effects of sex differences in immune responses at mucosal effector sites.

RESUMO

OBJECTIVES: ARTEMIS demonstrated significantly greater efficacy of once-daily darunavir/ritonavir (DRV/r) 800/100 mg versus lopinavir/ritonavir 800/200 mg (total daily dose) in treatment-naïve, HIV-1-infected patients at week 96. The influence of baseline characteristics on efficacy and safety was analyzed in DRV/r patients. METHODS: Patients received once-daily DRV/r plus fixed-dose tenofovir/emtricitabine. Week 96 efficacy and safety data were analyzed by gender (males, n=239; females, n=104), age (≤30, n=115; 31-45, n=175; >45, n=53), race (Asian, n=44; Black, n=80; Caucasian/White, n=137; Hispanic, n=77), and hepatitis B and/or C virus coinfection (n=43). RESULTS: Week 96 virologic response rates (HIV-1 RNA<50 copies/mL) were as follows: gender: 79% for both males and females; age: 72% (≤30), 81% (31-45), and 89% (>45); race: 96% (Asian), 71% (Black), 77% (Caucasian/White), and 79% (Hispanic); coinfection status: 72% (coinfected) and 80% (non-coinfected). The incidence of treatment-related adverse drug reactions (ADRs) and laboratory abnormalities were comparable across gender, age, and race subgroups. Coinfected patients had a higher incidence of liver-related ADRs than non-coinfected patients. CONCLUSIONS: DRV/r 800/100 mg qd is an effective, well-tolerated treatment option for treatment-naïve patients of different gender, age, race, or coinfection status.

RESUMO

Interruption of suppressive highly active antiretroviral therapy (HAART) in HIV-infected patients leads to increased HIV replication and viral rebound in peripheral blood. Effects of therapy interruption on gut-associated lymphoid tissue (GALT) have not been well investigated. We evaluated longitudinal changes in viral replication and emergence of viral variants in the context of T cell homeostasis and gene expression in GALT of three HIV-positive patients who initiated HAART during primary HIV infection but opted to interrupt therapy thereafter. Longitudinal viral sequence analysis revealed that a stable proviral reservoir was established in GALT during primary HIV infection that persisted through early HAART and post-therapy interruption. Proviral variants in GALT and peripheral blood mononuclear cells (PBMCs) displayed low levels of genomic diversity at all times. A rapid increase in viral loads with a modest decline of CD4(+) T cells in peripheral blood was observed, while gut mucosal CD4(+) T cell loss was severe following HAART interruption. This was accompanied by increased mucosal gene expression regulating interferon (IFN)-mediated antiviral responses and immune activation, a profile similar to those found in HAART-naive HIV-infected patients. Sequence analysis of rebound virus suggested that GALT was not the major contributor to the postinterruption plasma viremia nor were GALT HIV reservoirs rapidly replaced by HIV rebound variants. Our data suggest an early establishment and persistence of viral reservoirs in GALT with minimal diversity. Early detection of and therapy for HIV infection may be beneficial in controlling viral evolution and limiting establishment of diverse viral reservoirs in the mucosal compartment.
