RESUMO
BACKGROUND: Chlamydia vaccines are currently under development and have the potential to lower the incidence of infection and disease, which are highest among adolescents and young adults. Ideally, a chlamydia vaccine would be administered to adolescents before sexual debut, a time when parents are the primary vaccine decision makers. This study explores parent opinions about an adolescent chlamydia vaccine to understand barriers and facilitators to uptake. METHODS: Semistructured interviews were conducted with parents of adolescents. Topics included conversations parents have with their children about chlamydia, opinions on chlamydia vaccine development, and vaccine characteristics, such as efficacy and cost. Interviews were analyzed using a thematic analysis approach. RESULTS: From March to April 2021, 21 interviews were completed. Few parents discuss chlamydia with their children and sex education was seen as limited. Overall, 16 parents indicated that a chlamydia vaccine is needed. However, there were mixed opinions about vaccinating their own children, related to the need to vaccinate at a young age, vaccine efficacy, and confusion about benefits of vaccination. Finally, healthcare provider recommendations were seen as important before deciding to vaccinate a child. CONCLUSIONS: Although parents think that chlamydia vaccines are needed, lack of awareness about infections and potential benefits of vaccination could serve as barriers to uptake. Healthcare provider recommendations can help to improve knowledge and vaccine uptake. However, there is a need for multilevel approaches to improve chlamydia awareness and ensure that vaccination initiation and completion rates remain high.

BACKGROUND: Chlamydia vaccination is a potentially important strategy to prevent infections and reduce the global burden of disease. Ideally, chlamydia immunization programs would require vaccinating adolescents before they engage in sexual activity. Communication by health care providers (HCPs) has been shown to have an impact on vaccine acceptance. Therefore, it is imperative to understand their opinions on chlamydia vaccines and factors that would promote strong vaccine recommendations to patients to promote uptake. METHODS: Semi-structured interviews with adolescent HCPs were conducted and focused on perceived need for chlamydia vaccine. Additional topics included vaccine characteristics, such as efficacy, cost, and booster vaccines, and potential vaccine recommendation strategies. RESULTS: From January to July 2021, 22 interviews were completed. Health care providers discussed how chlamydia vaccines are needed, especially in settings with high prevalence rates. Health care providers thought a chlamydia vaccine would need to be very efficacious in preventing infections and related sequalae and cost-effective. However, there were concerns about low completion rates if this vaccine required multiple doses or boosters. In addition, vaccine misinformation was prevalent among HCPs regarding potential benefits of vaccination. CONCLUSIONS: Health care providers' perceptions that an adolescent chlamydia vaccine would be beneficial offers great promise for future promotion. However, there is need for targeted education programs about chlamydia and the benefits of vaccination for HCPs. These programs will be especially important in order for HCPs to effectively communicate about the benefits of vaccination to parents and adolescents provide strong vaccine recommendations.

BACKGROUND: The effectiveness of hepatitis C testing and linkage-to-care (LTC) is poorly characterized in low-resource jurisdictions facing gaps in harm reduction, including illegality of syringe exchange services. Effectiveness of a community-based test/LTC program was evaluated in Alabama. METHODS: In 2016-2018, shelters, drug treatment centers (DTCs), AIDS organizations, and Federally Qualified Health Centers (FQHCs) engaged in screening/LTC. A coordinator navigated individuals to confirm viremia and link to substance use treatment or primary care with hepatitis C prescribers. RESULTS: Point-of-care (POC) tested 4293 individuals (10% [427] antibody-positive, 71% [299/419] RNA performed, 80% [241/299] viremia confirmed) and 93% linked to care (225/241). Electronic medical record (EMR)-based reflex strategy screened 4654 (15% [679] antibody positive, 99% [670/679] RNA performed, 64% [433/679] viremia confirmed) and 85% linked to care (368/433). We observed higher odds of RNA confirmation in EMR-based reflex versus POC (OR, 2.07; Pâ <â .0001) and higher odds of LTC in EMR-based reflex versus POC (OR, 1.51; Pâ <â .0001). Overall, 53% individuals tested were nonbaby boomers. CONCLUSIONS: In Alabama, screening at high-risk settings identified significant hepatitis C burden and reflex testing outperformed point-of-care linkage indicators. Colocating testing in DTCs and treatment in FQHCs provided key LTC venues to at-risk younger groups.

BACKGROUND: The durability and breadth of human immunodeficiency virus type 1 (HIV-1)-specific immune responses elicited through vaccination are important considerations in the development of an effective HIV-1 vaccine. Responses to HIV-1 envelope subunit protein (Env) immunization in humans are often described as short-lived. METHODS: We enrolled 16 healthy volunteers who had received priming with an HIV-1 subtype B Env vaccine given with MF59 adjuvant 5-17 years previously and 20 healthy unprimed volunteers. Three booster immunizations with a heterologous subtype C trimeric gp140 protein vaccine were administered to the primed group, and the same subtype C gp140 protein vaccination regimen was administered to the unprimed subjects. RESULTS: Binding antibodies and neutralizing antibodies to tier 1 viral isolates were detected in the majority of previously primed subjects. Remarkably, a single dose of protein boosted binding and neutralizing antibody titers in 100% of primed subjects following this prolonged immunologic rest period, and CD4+ T-cell responses were boosted in 75% of primed individuals. CONCLUSIONS: These results demonstrate that HIV-1 protein immunogens can elicit durable memory T- and B-cell responses and that strong tier 1 virus neutralizing responses can be elicited by a single booster dose of protein following a long immunologic rest period. However, we found no evidence that cross-clade boosting led to a significantly broadened neutralizing antibody response.

BACKGROUND: Cardiovascular disease (CVD) is more frequent among people with HIV (PWH) and may relate to traditional and nontraditional factors, including inflammation and immune activation. A critical need exists to develop effective strategies to prevent CVD in this population. METHODS: The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) (A5332) is a prospective, randomized, placebo-controlled trial of a statin strategy for the primary prevention of major adverse cardiovascular events (MACE) in PWH with low to moderate traditional risk. At least 7,500 PWH, 40-75 years of age, on stable antiretroviral therapy, will be randomized to pitavastatin calcium (4 mg/d) or identical placebo and followed for up to 8 years. Participants are enrolled based on the 2013 American College of Cardiology (ACC)/American Heart Association (AHA) atherosclerotic cardiovascular disease (ASCVD) risk score and low-density lipoprotein cholesterol (LDL-C) level with a goal to identify a low- to moderate-risk population who might benefit from a pharmacologic CVD prevention strategy. Potential participants with a risk score ≤ 15% were eligible based on decreasing LDL-C thresholds for increasing risk score >7.5% (LDL-C <190 mg/dL for risk score <7.5%, LDL-C <160 mg/dL for risk score 7.6%-10%, and LDL-C<130 mg/dL for risk score 10.1%-15%). The primary objective is to determine effects on a composite end point of MACE. Formal and independent adjudication of clinical events will occur using standardized criteria. Key secondary end points include effects on MACE components, all-cause mortality, specified non-CVD events, AIDS and non-AIDS events, and safety. RESULTS: To date, REPRIEVE has enrolled >7,500 participants at approximately 120 sites across 11 countries, generating a diverse and representative population of PWH to investigate the primary objective of the trial. CONCLUSIONS: REPRIEVE is the first trial investigating a primary CVD prevention strategy in PWH. REPRIEVE will inform the field of the efficacy and safety of a statin strategy among HIV-infected participants on antiretroviral therapy and provide critical information on CVD mechanisms and non-CVD events in PWH.

BACKGROUND: People with HIV (PWH) have increased cardiovascular events, inflammation, and high-risk coronary atherosclerosis. Statin therapy has been shown to lower the risk of cardiovascular disease (CVD) in the general population, but whether this results from reductions in coronary atherosclerosis and is mediated by decreased inflammation remains unknown. METHODS: REPRIEVE is a randomized, placebo-controlled trial of pitavastatin calcium (4 mg/day) vs. placebo enrolling at least 7500 PWH between 40-75 years, on antiretroviral therapy (ART), with low to moderate traditional CVD risk. The Mechanistic Substudy of REPRIEVE (A5333s) is co-enrolling 800 participants from 31 US sites. These participants undergo serial contrast enhanced coronary computed tomography angiography (CCTA) and measurements of biomarkers of inflammation and immune activation at baseline and after 2 years of follow-up. The primary objectives are to determine the effects of pitavastatin on noncalcified coronary atherosclerotic plaque (NCP) volume, low attenuation plaque, and positive remodeling and on changes in immune activation and inflammation and to assess relationships between the two. Changes in CAD will be assessed in a standardized fashion by a core lab with expert readers blinded to time points and participant information; immune activation and inflammation assessment is also performed centrally. RESULTS: To date the Mechanistic Substudy has completed planned enrollment, with 805 participants. CONCLUSION: This study represents the first large, randomized, CCTA-based assessment of the effects of a primary prevention strategy for CVD on high-risk CAD, immune activation and inflammation among PWH. The study will assess pitavastatin's effects on coronary plaque, and the interrelationship of these changes with biomarkers of immune activation and inflammation in PWH to determine mechanisms of CVD prevention and improved outcomes in this population.

BACKGROUND: The combination of daclatasvir, a hepatitis C virus (HCV) NS5A inhibitor, and the NS5B inhibitor sofosbuvir has shown efficacy in patients with HCV monoinfection. Data are lacking on the efficacy and safety of this combination in patients coinfected with human immunodeficiency virus type 1 (HIV-1). METHODS: This was an open-label study involving 151 patients who had not received HCV treatment and 52 previously treated patients, all of whom were coinfected with HIV-1. Previously untreated patients were randomly assigned in a 2:1 ratio to receive either 12 weeks or 8 weeks of daclatasvir at a standard dose of 60 mg daily (with dose adjustment for concomitant antiretroviral medications) plus 400 mg of sofosbuvir daily. Previously treated patients were assigned to undergo 12 weeks of therapy at the same doses. The primary end point was a sustained virologic response at week 12 after the end of therapy among previously untreated patients with HCV genotype 1 who were treated for 12 weeks. RESULTS: Patients had HCV genotypes 1 through 4 (83% with genotype 1), and 14% had compensated cirrhosis; 98% were receiving antiretroviral therapy. Among patients with genotype 1, a sustained virologic response was reported in 96.4% (95% confidence interval [CI], 89.8 to 99.2) who were treated for 12 weeks and in 75.6% (95% CI, 59.7 to 87.6) who were treated for 8 weeks among previously untreated patients and in 97.7% (95% CI, 88.0 to 99.9) who were treated for 12 weeks among previously treated patients. Rates of sustained virologic response across all genotypes were 97.0% (95% CI, 91.6 to 99.4), 76.0% (95% CI, 61.8 to 86.9), and 98.1% (95% CI, 89.7 to 100), respectively. The most common adverse events were fatigue, nausea, and headache. There were no study-drug discontinuations because of adverse events. HIV-1 suppression was not compromised. CONCLUSIONS: Among previously untreated HIV-HCV coinfected patients receiving daclatasvir plus sofosbuvir for HCV infection, the rate of sustained virologic response across all genotypes was 97.0% after 12 weeks of treatment and 76.0% after 8 weeks.

CAD is a well-established comorbidity associated with HIV infection. This association is in large part due to ongoing inflammation propagated by viremia and dysregulation of the immune system. Despite this knowledge, evidence to guide clinical management and screening for CAD among HIV-infected patients is lacking. The following editorial discusses recent evidence that HIV-infected patients with abnormal cardiovascular stress testing are more likely to undergo subsequent percutaneous coronary intervention. Importantly, the cardiovascular consequences of HIV infection and potential clinical implications are discussed.

BACKGROUND: Although statins, angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) are generally well tolerated, the impact of these therapies individually or in combination on the change in neurocognitive function in persons with human immunodeficiency virus infection is unknown. METHODS: The study included participants in the AIDS Clinical Trials Group Longitudinal Linked Randomized Trials cohort participants not receiving a statin or ACEI/ARB within 30 days of first neurologic assessment (baseline), with assessments by NPZ-3 (z score of averaged Trailmaking A and B tests and digit symbol test [DST]) from ≥2 measurements. Marginal structural models estimated the causal effect of statin or ACEI/ARB initiation on neurocognitive function; initial constant slope was assumed during the first year of treatment and a second constant slope thereafter. RESULTS: Of 3949 eligible participants, 16% started therapy with a statin, 11% with an ACEI/ARB, and 5% with both. Statin therapy had no significant effect on the composite NPZ-3 (primary outcome), Trailmaking B test, or DST. A small, nonsignificant positive effect on the Trailmaking A test was seen during year 1 (estimate, 0.088; 95% confidence interval, -.010 to .187; P = .08) and a small but significant negative effect (-0.033; -.058 to -.009; P = .007) in each subsequent year. ACEI/ARB therapy had a significant negative effect on the DST (-0.117; 95% confidence interval, -.217 to .016; P = .02) during year 1 but minimal effect in subsequent years or on other neurocognitive domains. CONCLUSIONS: In summary, although modest declines in neurocognitive performance were seen in single domains with statin or ACEI/ARB therapy, we did not find consistent evidence that statins or ACEI/ARB have an effect on global neurocognitive function. Future studies should focus on long-term neurocognitive effects.

BACKGROUND: The phase 4, METABOLIK trial demonstrated that changes in metabolic parameters with darunavir with low-dose ritonavir (DRV/r) were comparable to those observed with atazanavir with low-dose ritonavir (ATV/r). A comprehensive assessment of the effects of these agents on insulin sensitivity will provide additional, relevant clinical information. METHODS: In this substudy of METABOLIK, HIV-1-infected, antiretroviral agent-naïve male subjects aged ≥18 years with a viral load of >1,000 copies/mL were randomized to receive DRV/r 800/100 mg once daily (qd) or ATV/r 300/100 mg qd, both with a fixed dose of tenofovir disoproxil fumarate/emtricitabine 300/200 mg qd. The effects of DRV/r versus ATV/r on insulin sensitivity over 48 weeks were compared using the euglycemic hyperinsulinemic clamp, the preferred method to assess insulin sensitivity; primary end point was the effect on insulin sensitivity during the first 12 weeks. RESULTS: Twenty-seven subjects completed the study. In the DRV/r arm (n=14), median glucose disposal from baseline through weeks 12 and 48 was 9.3, 11.4, and 9.9 mg/kg*min, respectively; in the ATV/r arm (n=13), these values were 8.9, 8.6, and 9.1 mg/kg*min, respectively. Median insulin sensitivity in the DRV/r arm at baseline, week 12, and week 48 was 24.0, 25.0, and 21.5 mg/kg*min per µIU/mL×100, respectively; these values in the ATV/r arm were 20.7, 22.0, and 22.0 mg/kg*min per µIU/mL×100, respectively. Most subjects had ≥1 adverse event, including three serious adverse events (n=2 [DRV/r], n=1 [ATV/r]). CONCLUSIONS: DRV/r and ATV/r displayed similar modest effects on insulin sensitivity using a euglycemic hyperinsulinemic clamp.

HIV infection and antiretroviral therapy (ART) use are associated with perturbations in glucose and lipid metabolism. Increasing incidence of diabetes, cardiovascular disease, and obesity highlights the need for early identification and treatment of metabolic dysfunction. Newer ART regimens are less toxic for cellular function and metabolism but have failed to completely eliminate metabolic dysfunction with HIV infection. Additional factors, including viral-host interactions, diet, physical activity, non-ART medications, and aging may further contribute to metabolic disease risk in the HIV setting. We summarize the recent literature regarding the impact on metabolic function of HIV infection, ART, and pharmaceutical or lifestyle prescriptions.

BACKGROUND: Antiretroviral therapy initiation for HIV-1 infection is associated with 2% to 6% loss of bone mineral density (BMD). OBJECTIVE: To evaluate the effect of vitamin D3 plus calcium supplementation on bone loss associated with antiretroviral therapy initiation. DESIGN: 48-week prospective, randomized, double-blind, placebo-controlled study. (ClinicalTrials.gov: NCT01403051). SETTING: 39 AIDS Clinical Trials Group units. PATIENTS: Adults with antiretroviral therapy-naive HIV. MEASUREMENTS: BMD by dual-energy x-ray absorptiometry, 25-hydroxyvitamin D levels, and other laboratory assessments. RESULTS: 165 eligible patients were randomly assigned (79 received vitamin D3 plus calcium and 86 received placebo). The study groups were well-balanced at baseline: 90% were men, 33% were non-Hispanic black, and the median CD4 count was 0.341 × 109 cells/L. At 48 weeks, the percentage of decline in total hip BMD was smaller in the vitamin D3 plus calcium group than in the placebo group: Medians were -1.36% (interquartile range [IQR], -3.43% to 0.50%) and -3.22% (IQR, -5.56% to -0.88%), respectively (P = 0.004). Similar results were seen at the lumbar spine. At 48 weeks, 90% of patients achieved HIV-1 RNA levels less than 50 copies/mL. Levels of 25-hydroxyvitamin D3 increased with vitamin D3 plus calcium but not with placebo: Median change was 61.2 nmol/L (IQR, 36.4 to 94.3) versus 1.7 nmol/L (IQR, -13.2 to 10.7) (P < 0.001). Overall, 103 patients (62%) reported 1 or more adverse event, with similar distribution between groups; no cases of hypercalcemia and 1 case of nephrolithiasis were reported in the placebo group. LIMITATION: No international sites were included, and follow-up was only 48 weeks. CONCLUSION: Vitamin D3 plus calcium supplementation mitigates the BMD loss seen with initiation of efavirenz/emtricitabine/tenofovir disoproxil fumarate.

Chronic pain in HIV-infected individuals is common and often undertreated. Physical therapy (PT) is an evidence-based nonpharmacologic treatment for chronic pain. Our objective is to present the results of a pilot PT program in an HIV pain/palliative care clinic, which is embedded within a Ryan White-funded multidisciplinary HIV primary care clinic. Medical records of HIV-infected patients participating in a PT program between November 2012 and July 2013 were retrospectively reviewed. Pain scores on a 0-10 scale and cost data were collected and analyzed. Among 43 patients referred, 27 collectively attended 86 sessions. Median age of enrolled patients was 54 (IQR 49-58). Sixteen (59%) were African-American and 20 (77%) had an undetectable HIV viral load. Mean pain score at initial visit was 6.5 (SD = 1.1). The average session-level decrease was 2.6 (SD = 1.7) and patient-level decrease was 2.5 (SD = 1.2). The largest payors were Medicare managed care (28%), Medicaid (21%), and Ryan White grant-related funds (18%). When the first four months of the program are excluded to account for slow start-up, the program's monthly net revenue during the remaining five months was $163. We present preliminary data from a low-cost pilot PT program integrated into an HIV clinic in a primary care setting associated with clinically significant improvements in pain. Further investigation into the implementation of such programs is essential.

Depression is a common comorbidity among HIV-infected individuals. We studied the relationship between depressive symptoms, risk behaviors (risky-sexual behavior, tobacco, alcohol, and illicit drug use) and HIV outcomes. This cross-sectional study conducted in 2009 at the Washington University HIV Clinic included screening for depression with patient health questionnaire, survey of sexual behavior, illicit drug, alcohol, and tobacco use within 30 days. Sociodemographics, plasma HIV RNA levels, CD4 cell counts, and sexually transmitted disease test results were obtained from medical records. Multivariate logistic and linear regression models were used to assess the association between depressive symptoms severity and risk behaviors, HIV outcomes and combination antiretroviral therapy (cART) adherence. A total of 624 persons completed the assessment of whom 432 (69%) were male and 426 (68%) African-American. The median CD4 cell count was 410 cells/mm(3) and 479 persons (77%) were on cART of whom 112 (23%) had HIV RNA level > 400 copies/mL. Overall, 96 (15%) had symptoms of major depressive disorder. Depressive symptom severity was associated with increased likelihood of high-risk drinking (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.1-5.1), current tobacco use (OR, 1.8; 95% CI, 1.1-2.9), illicit drug use (OR, 1.7; 95% CI, 1.0-2.8), and risky-sexual behavior (OR, 1.5; 95% CI, 0.8-2.7). Suboptimal cART adherence (visual analog scale < 95%) was also associated with depressive symptoms severity (p < 0.05). After adjustment for age, sex, race, receipt of cART, and cART adherence, depressive symptoms severity was independently associated with lower CD4 cell count (p < 0.05) but not with higher HIV RNA level (p = 0.39). Depression adversely affects HIV-infected individuals, requiring greater effort at utilizing multidisciplinary interventions.

BACKGROUND: Human immunodeficiency virus (HIV)-infected persons are at higher risk for serious complications associated with traditional smallpox vaccines. Alternative smallpox vaccines with an improved safety profile would address this unmet medical need. METHODS: The safety and immunogenicity of modified vaccinia Ankara (MVA) was assessed in 91 HIV-infected adult subjects (CD4(+) T-cell counts, ≥350 cells/mm(3)) and 60 uninfected volunteers. The primary objectives were to evaluate the safety of MVA and immunogenicity in HIV-infected and uninfected subjects. As a measure of the potential efficacy of MVA, the ability to boost the memory response in people previously vaccinated against smallpox was evaluated by the inclusion of vaccinia-experienced HIV-infected and HIV-uninfected subjects. RESULTS: MVA was well tolerated and immunogenic in all subjects. Antibody responses were comparable between uninfected and HIV-infected populations, with only 1 significantly lower total antibody titer at 2 weeks after the second vaccination, while no significant differences were observed for neutralizing antibodies. MVA rapidly boosted the antibody responses in vaccinia-experienced subjects, supporting the efficacy of MVA against variola. CONCLUSIONS: MVA is a promising candidate as a safer smallpox vaccine, even for immunocompromised individuals, a group for whom current smallpox vaccines have an unacceptable safety profile.

The diagnosis of human immunodeficiency virus (HIV)-associated neurocognitive impairment is time-intensive and often omitted in busy outpatient settings. Brief screening tools are needed. The Montreal Cognitive Assessment (MoCA) and the Alzheimer's disease (AD)-8 have been used in neurodegenerative disorders. We evaluated the sensitivity and specificity of these brief screening tools in HIV-infected persons. The AD-8, MoCA, and formal neuropsychological testing were administered to 200 HIV-infected patients who were followed at a single institution. Normalized scores on formal neuropsychological testing were used to define neurocognitive impairment. The sensitivity and specificity of the MoCA and AD-8 were assessed to diagnose the impairment. Neurocognitive impairment was highly prevalent in this cohort: 127 persons (64 %) were diagnosed with neurocognitive impairment based on formal testing. Using the AD-8 and MoCA, 113 (57 %) and 101 (51 %) persons were identified with neurocognitive impairment, respectively. The sensitivity and specificity of MoCA were 63 % and 71 %, respectively. The sensitivity and specificity of AD-8 were 61 % and 51 %, respectively. Our findings highlight that brief screening tools correlate with formal neuropsychological testing. However, the sensitivities of these screening tools are lower than desired. Nevertheless, given their ease in administration, these tools could assist as a first line for identifying individuals who may subsequently require formal neuropsychological testing.

BACKGROUND: We compared the herpes simplex virus type 2 (HSV-2) seroprevalence in a contemporary HIV cohort with the general US population and determined risk factors for HSV-2 infection among HIV-infected persons. METHODS: The Study to Understand the Natural History of HIV and AIDS in the Era of Effective Therapy (SUN) Study is a prospective observational cohort of 700 HIV-infected adults enrolled in 4 U.S. cities between 2004 and 2006. At baseline, participants completed a behavioral risk questionnaire and provided specimens for HSV-2 serology. We calculated HSV-2 seroprevalence, standardized by age, gender, and race among HIV-infected persons compared with the general US adult population, using data from the National Health and Nutrition Examination Survey from 2003 to 2006. We examined risk factors associated with HSV-2 infection among HIV-infected persons using multivariate logistic regression. RESULTS: Among 660 (94%) SUN participants with adequate specimens for HSV-2 serologic testing, 548 (83%) were 20 to 49 years old (median age, 39 years; 77% male; 59% non-Hispanic white; median CD4 count, 470 cells/mm; 74% with HIV RNA viral loads <400 copies/mL). HSV-2 seroprevalence was significantly higher among HIV-infected adults (59.7%, 95% confidence interval: 55.8-63.6) compared with the general US population (19.2%, 95% confidence interval: 17.5-21.1). In multivariate analysis, we found that older age, female gender, black non-Hispanic race/ethnicity, being currently unemployed, high-risk anal HPV infection, and longer duration since HIV diagnosis were associated with significantly higher odds of HSV-2 infection. CONCLUSION: HSV-2 seroprevalence is 3 times as high among HIV-infected adults as in the general U.S. population. Clinicians should be aware that increased risk for HSV-2 infection was distributed broadly among HIV-infected persons and not limited to those with high-risk sexual behaviors.

Highly active antiretroviral therapy regimens, consisting of a ritonavir-boosted protease inhibitor (PI) and 2 nucleoside reverse transcriptase inhibitors, are established first-line regimens for HIV-infected patients. However, a common adverse effect in patients receiving PIs is dyslipidemia, characterized by increases in plasma levels of triglycerides, low-density lipoprotein cholesterol, and total cholesterol (TC). These lipid changes, as well as other well-described risk factors, may predispose patients to the development of cardiovascular disease, an important comorbidity, especially as the lifespan of HIV-infected patients has increased dramatically in recent years. Among PIs, ritonavir-boosted atazanavir (ATV/r) and, more recently, ritonavir-boosted darunavir (DRV/r) have demonstrated potent antiviral efficacy with more favorable lipid profiles than other PIs. This review provides an overview of the lipid effects of DRV/r. Studies with DRV/r in healthy volunteers and in both treatment-naïve and -experienced patients have demonstrated that changes in tri-glycerides and TC are comparable to those seen with ATV/r.

Individuals with HIV experience fluctuating levels of distress throughout the course of their infection. This cross-sectional study was conducted to examine the prevalence of and associations between anxiety symptoms, sociodemographic, and biomedical markers among individuals presenting for care. A total of 635 individuals were screened, the majority of whom was male and African American. Younger individuals, African Americans, individuals with less education, and those who were unemployed were more likely to express more severe anxiety symptoms. Individuals who were not currently receiving antiretroviral therapy (ART) were 1.61 times more likely to experience higher anxiety symptoms. Among individuals receiving ART, higher levels of anxiety were associated with less adherence, higher viral loads and lower CD4 cell counts. Current smokers were 1.66 times more likely to have higher rates of anxiety. When controlling for these significant factors, younger, unemployed, and less educated individuals were more likely to express more severe anxiety symptoms. These findings highlight the importance of screening and management of anxiety as an integral component of HIV care.

Hypertension (HTN) is a common comorbidity among people with HIV and associated with an increased risk for atherosclerotic cardiovascular disease and chronic kidney disease. The relationship of antiretroviral therapy (ART) initiation to incident HTN remains a clinical question. We determined HTN incidence at 48 weeks of follow-up among ART-naive participants without HTN and not taking antihypertensive medications at ART initiation through randomized clinical trials through the AIDS Clinical Trial Group between 1999 and 2011. We assessed the association of baseline characteristics, including randomized ART agents with HTN incidence at 48 weeks using Poisson regression models. Incident HTN was defined as blood pressure ≥130/80 mmHg, or use of antihypertensive medication. Among 2,614 participants, mean age was 37 ± 10 years, 79% male sex, and 36% African American race. After 48 weeks, 839 participants (32%) developed HTN. Receiving a non-nucleoside reverse transcriptase inhibitor (NNRTI) was associated with an increased relative risk (RR) of incident HTN, while the risk was lower for protease inhibitor use. Stavudine and efavirenz were associated with an increased RR of developing HTN, while tenofovir disoproxil fumarate, darunavir/ritonavir, and atazanavir/ritonavir were associated with a decreased risk of developing HTN. Additionally, older age, higher body mass index (BMI), and having hepatitis C were associated with an increased risk for developing HTN, while women and participants with a higher baseline CD4 count were at a decreased risk of developing HTN at 48 weeks. One third of these ART naive participants developed HTN after ART initiation. NNRTIs, notably efavirenz, and stavudine were associated with an increased risk of HTN. Additional factors associated with HTN included traditional factors like older age and higher BMI, and advanced HIV disease (lower CD4 count). (Clinicaltrials.gov: NCT00001137).
