RESUMEN

Importance: Despite higher atherosclerotic cardiovascular disease (ASCVD) risk, people with HIV (PWH) experience unique barriers to ASCVD prevention, such as changing models of HIV primary care. Objective: To test whether a multicomponent nurse-led strategy would improve systolic blood pressure (SBP) and non-high-density lipoprotein (HDL) cholesterol level in a diverse population of PWH receiving antiretroviral therapy (ART). Design, Setting, and Participants: This randomized clinical trial enrolled PWH at 3 academic HIV clinics in the US from September 2019 to January 2022 and conducted follow-up for 12 months until January 2023. Included patients were 18 years or older and had a confirmed HIV diagnosis, an HIV-1 viral load less than 200 copies/mL, and both hypertension and hypercholesterolemia. Participants were stratified by trial site and randomized 1:1 to either the multicomponent EXTRA-CVD (A Nurse-Led Intervention to Extend the HIV Treatment Cascade for Cardiovascular Disease Prevention) intervention group or the control group. Primary analyses were conducted according to the intention-to-treat principle. Intervention: The EXTRA-CVD group received home BP monitoring guidance and BP and cholesterol management from a dedicated prevention nurse at 4 in-person visits (baseline and 4, 8, and 12 months) and frequent telephone check-ins up to every 2 weeks as needed. The control group received general prevention education sessions from the prevention nurse at each of the 4 in-person visits. Main Outcomes and Measures: Study-measured SBP was the primary outcome, and non-HDL cholesterol level was the secondary outcome. Measurements were taken over 12 months and assessed by linear mixed models. Prespecified moderators tested were sex at birth, baseline ASCVD risk, and trial site. Results: A total of 297 PWH were randomized to the EXTRA-CVD arm (n = 149) or control arm (n = 148). Participants had a median (IQR) age of 59.0 (53.0-65.0) years and included 234 males (78.8%). Baseline mean (SD) SBP was 135.0 (18.8) mm Hg and non-HDL cholesterol level was 139.9 (44.6) mg/dL. At 12 months, participants in the EXTRA-CVD arm had a clinically significant 4.2-mm Hg (95% CI, 0.3-8.2 mm Hg; P = .04) lower SBP and 16.9-mg/dL (95% CI, 8.6-25.2 mg/dL; P < .001) lower non-HDL cholesterol level compared with participants in the control arm. There was a clinically meaningful but not statistically significant difference in SBP effect in females compared with males (11.8-mm Hg greater difference at 4 months, 9.6 mm Hg at 8 months, and 5.9 mm Hg at 12 months; overall joint test P = .06). Conclusions and Relevance: Results of this trial indicate that the EXTRA-CVD strategy effectively reduced BP and cholesterol level over 12 months and should inform future implementation of multifaceted ASCVD prevention programs for PWH.

RESUMEN

BACKGROUND: This study examined the relationships among adiposity, handgrip, physical function, inflammation (ie, senescence-associated secretory phenotype chemokines as biomarkers of aging and frailty), and sex hormones in aging people with HIV. METHODS: This cross-sectional exploratory study included 150 people with HIV aged ≥40 years (67.3% of participants were male). Our measures included (1) body mass index and waist circumference as measures of adiposity; (2) handgrip as a measure of muscle strength; (3) short physical performance battery as a measure of physical function; (4) interleukin-6, tumor necrosis factor alpha receptor II, high sensitivity C-reactive protein, C-X-C motif chemokine 10, and C-X3-C motif chemokine ligand 1 also known as fractalkine as senescence-associated secretory phenotype chemokines; and (5) free testosterone, estradiol, sex hormone-binding globulin, and dehydroepiandrosterone as sex hormones. Quantile regression analyses were used to identify relationships among inflammatory markers and hormones with age, adiposity, handgrip, and physical function. RESULTS: Overall, 74% (n = 111) of participants were classified as overweight or obese and 53.3% (n = 80) presented with abdominal obesity. After controlling for age and sex, body mass index was positively associated with estradiol (ß = 0.043, P < 0.01), and waist circumference was positively associated with high sensitivity C-reactive protein (ß = 2.151, P < 0.01). After controlling for sex, age was positively associated with C-X-C motif chemokine 10 (ß = 0.024, P = 0.03) and tumor necrosis factor alpha receptor II (ß = 2.205, P = 0.01). After controlling for age and sex, short physical performance battery was negatively associated with dehydroepiandrosterone (ß = -0.004, P = 0.01); no statistically significant associations were observed for handgrip. CONCLUSION: Adiposity levels and aging were associated with inflammation (ie, C-X-C motif chemokine 10, tumor necrosis factor alpha receptor II, and high sensitivity C-reactive protein) among people with HIV aged 40 years and older.

RESUMEN

Human immunodeficiency virus (HIV) infection is now preventable with pre-exposure prophylaxis (PrEP) drugs, however, barriers to PrEP implementation include primary-care physician (PCP) knowledge-gap and lack of comfort prescribing and managing PrEP. We hypothesized that integrating HIV-PrEP education during medical-residency would help address these problems and developed a 40-minute case-based lecture focused on the 2021 United States Preventative Services Taskforce (USPSTF) oral HIV-PrEP guidelines and integrated this into our residency's core curriculum. We analyzed data from physician-trainees who voluntarily completed a pre- and post-lecture survey measuring HIV-PrEP "knowledge" and "self-assessed readiness to independently initiate and manage PrEP." Independent group analysis was completed via the Mann-Whitney U and Pearson Chi-square 2-sided test with P-value <0.05 deemed significant. Of the total of 189 residents invited to the lecture, 130 (69%) completed the pre-survey while 107 (57%) completed the post-survey. Per knowledge-assessment: the median number of correctly answered questions rose from a pre-lecture baseline of 4/9 (44%) to 8/9 (89%) following the education intervention (P < .001). When asked about comfort initiating and managing HIV-PrEP on their own, 7/130 (5.4%) responded in agreement pre-lecture, but this rose to 55/107 (51.4%) post-lecture (P < .001). Our study revealed PrEP training during residency was effective per stated objectives and may be an important tool to increase PrEP delivery/uptake to achieve the target goals for the National HIV/AIDS Strategy.

RESUMEN

OBJECTIVES: People with HIV (PWH) are aging and are experiencing higher rates of abdominal adiposity. Physical activity is an effective nonpharmacological strategy to reduce adiposity in the general aging population. Yet, the relationship between physical activity and adiposity in people with well controlled HIV is unclear. Our objective was to describe the association between objectively-measured physical activity and abdominal adiposity in PWH. METHODS: As part of the multisite, observational PROSPER-HIV study, virologically suppressed, adult PWH wore an Actigraph accelerometer for 7-10 days and completed duplicate waist and hip circumference measures. Demographic and medical characteristics were abstracted from the CFAR Network of Integrated Clinical Systems dataset. Descriptive statistics and multiple linear regressions were used to analyze the data. RESULTS: On average, our 419 PWH were 58 years of age [interquartile range (IQR): 50, 64], male (77%), Black (54%), and currently taking an integrase inhibitor (78%). PWH completed a mean of 7.06 (±2.74) days of total actigraphy wear time. They took an average of 4905 (3233, 7140) steps per day and engaged in 5.4 h of sedentary time per day. Controlling for age, sex, employment and integrase inhibitor use, the number of steps taken per day was associated with reduced abdominal adiposity ( F  = 3.27; P  < 0.001) and the hours of daily sedentary time was associated with increased abdominal adiposity ( F  = 3.24; P  < 0.001). CONCLUSIONS: Greater physical activity is associated with reduced abdominal adiposity in aging PWH. Future work should investigate how to tailor the amount, type and intensity of physical activity needed to reduce adiposity in PWH taking contemporary HIV medication. REGISTRATION NUMBER: NCT03790501.

RESUMEN

The incidence of syphilis infections is on the rise, particularly among African American men and men who have sex with men, and it is reaching epidemic levels in these communities throughout the United States. Although syphilis is relatively inexpensive to treat and cure and is a predictor for HIV incidence among men and transgender women who have sex with men, rates of co-screening for syphilis are low in the emergency department setting, with a dearth of literature on this topic since the 1990s and early 2000s. In this case study, we describe an operational model for routine syphilis screening implemented in June 2017 at the University Hospitals Cleveland Medical Center in Cleveland, Ohio. We describe the advantages of screening using a reverse testing algorithm rather than the traditional method and the necessity of partnering with the Cleveland Department of Public Health for both diagnostic and follow-up logistics.

RESUMEN

BACKGROUND: The use of combination antiretroviral therapy (cART) has significantly decreased the morbidity and mortality associated with human immunodeficiency virus (HIV) infection. Lipid disorders, including lipodystrophy, hypertriglyceridemia, and hypercholesterolemia, remain the most commonly reported metabolic disorders among those treated with long-term cART. Mounting evidence suggests an association between drug abuse and poor glycemic control and diabetes complications. Substance related disorders (SRD) may increase the risk of metabolic syndrome. MATERIALS AND METHODS: The aim of this retrospective cohort study was to examine the relationship between SRD, cART, and lipid-lowering agent use in an HIV infected population. Patients received efavirenz or protease inhibitor-based cART for at least 6 months. Prescription information was retrieved from the medical records. The primary outcome was the use of lipid-lowering agents including statins, fibrates and fish oil. The impact of SRD and cART was assessed on the lipid-lowering agent use. RESULTS: A total of 276 subjects with HIV infection were included, 90 (33%) received lipid-lowering agents, and 31 (34%) had SRD. Smoking was prevalent among subjects with SRD (84 vs 15%, p<0.001). Statins were the mainstay for the management of dyslipidemia (66%), followed by the fibrates (24%), omega-3 fatty acids (5%), nicotinic acid (3%) and the cholesterol absorption inhibitors (3%). Use of statins or fibrates was significantly higher among subjects without SRD than those with (40 vs 23%, p=0.005). The type of cART, including efavirenz and protease inhibitors, appeared to have no significant impact on the use pattern of lipid-lowering agents. Lopinavir/ritonavir (lopinavir/r) was mostly prescribed for subjects with SRD (25 vs 8%, p=0.02). CONCLUSION: Among HIV-infected patients, statins remain the mainstay for the management of dyslipidemia in routine clinical care, followed by fibrates. A significant high risk of metabolic disorders among patients with SRD is implicated by heavy tobacco use and prevalent lopinavir/r-based treatment. Significantly low rate of lipid-lowering agent use in this population underscores the importance of lipid disorder scrutiny and cART treatment optimization for HIV-infected patients with SRD.

RESUMEN

BACKGROUND: Several studies have reported increased resting energy expenditure (REE) in people with human immunodeficiency virus (HIV). However, limited data exist on REE in HIV-infected women and the effect of antiretroviral therapy (ART) on REE in this population. OBJECTIVE: The purpose of this study was to compare REE in healthy controls to adult HIV-infected women classified in three groups: naïve to ART, on ART with virologic suppression, and on ART with an HIV-1 RNA level >5,000 copies/mL. DESIGN: After a fast, body composition by bioelectrical impedance analysis and REE by indirect calorimetry were determined. Anthropometric measures were also taken. STATISTICAL ANALYSIS: Distributionally appropriate two-sample tests were used for between-group analyses and analysis of covariance was used for confounding adjustment. RESULTS: Eighty-seven women were enrolled and the HIV-infected and control women were matched for age and body mass index. Log-transformed REE was significantly higher in HIV-infected women naïve to ART compared to controls (7.26±0.22 vs 7.14±0.19; P=0.04, respectively) and the difference remained significant after adjustment for body cell mass (P=0.008). Log-transformed REE was not different in HIV-infected women on ART compared to HIV-infected women naïve to ART (7.25±0.25 vs 7.26±0.23; P=0.81, respectively). Adjusting for body cell mass did not change the results (P=0.56). Similarly, REE was not different between women naïve to ART and those on ART with undetectable HIV-1 RNA, regardless of adjustment for body cell mass. REE correlated to current and nadir CD4 count and trended toward a negative correlation with HIV-1 RNA levels. CONCLUSIONS: We showed that REE is elevated in ART-naïve, HIV-infected women and continues to be elevated when on ART, regardless of virologic suppression, compared to age and body mass index-matched healthy women. This suggests an effect of HIV infection itself and not ART on REE in these HIV-infected women, and should be considered during nutrition assessment and counseling of HIV-infected adult women.

RESUMEN

BACKGROUND: Achieving targeted antiretroviral (ARV) plasma concentrations during long-term treatment in human immunodeficiency virus (HIV)-infected patients with substance-related disorders (SRDs) may be challenging due to a number of factors, including medication adherence, coinfection with hepatitis B or C virus, medication intolerance, and drug interactions. One approach to investigate these factors is to conduct therapeutic drug monitoring to measure ARV exposure during treatment. The objective of this study was to utilize therapeutic drug monitoring to compare efavirenz (EFV) and protease inhibitor pharmacokinetics in patients with and without SRDs. METHODS: This was a multicenter, cross-sectional open-label study in patients with HIV-1 infection receiving antiretroviral therapy (ART), with active (n=129) or without (n=146) SRD according to National Institute on Drug Abuse criteria. Two hundred seventy-five subjects who were receiving either protease inhibitor-based or EFV-based ART regimens for >6 months were enrolled at 4 HIV treatment centers with an equal distribution of SRD and non-SRD at each site. The patients were instructed during enrollment visits with regard to the importance of adherence before and after study visits. Demographics and routine clinical laboratory tests were recorded. RESULTS: Among the 275 patients, 47% had SRD with at least 1 substance. There were no significant differences between SRD and non-SRD groups for race, gender, age, or CD4 count at entry. A significantly higher proportion of patients with SRD had an entry HIV RNA plasma concentration>75 copies per milliliter compared with patients without SRD (40% vs 28%, P=0.044). Logistic regression modeling revealed an association between HIV RNA plasma concentration and African American race (P=0.017). A significantly higher proportion of SRDs also had an EFV or protease inhibitor trough concentration below the desired range (23% vs 9%, P=0.048). Significantly lower trough concentrations were noted in patients with SRDs receiving atazanavir (0.290 vs 0.976 µg/mL) or lopinavir (3.75 vs 5.30 µg/mL). CONCLUSIONS: The pharmacokinetic data indicate differences between HIV-infected patients with and without SRDs that may influence viral load suppression during long-term ART. These findings require additional investigation in a randomized design with more intensive pharmacokinetic assessment to identify individual factors that are contributing to suboptimal ARV exposure in patients with SRDs.

RESUMEN

In this 13-week, open-label, randomized study of the anti-inflammatory salsalate versus usual care, there were no significant improvements in flow-mediated dilation of the brachial artery, endothelial activation, inflammation or coagulation markers, homeostasis model assessment of insulin resistance or lipoproteins with salsalate or between groups in virologically suppressed, HIV-infected adults on antiretrovirals. Tinnitus and transaminitis occurred frequently in the salsalate group. Dose reduction due to toxicities encountered and low level of inflammation may explain these results.

RESUMEN

INTRODUCTION: HIV-infected patients receiving protease inhibitors may benefit from therapeutic drug monitoring-assisted dose adjustment to achieve target plasma concentrations. However, efflux pumps such as permeability-glycoprotein, which is encoded by the multidrug resistance (MDR)1 gene, may decrease intracellular drug concentrations, thus reducing the amount of drug at the site of action. Plasma concentrations of protease inhibitors and CD4 cell count response have been associated with the T allele at the MDR1 C3435T locus. We examined MDR1 single nucleotide polymorphisms in a cohort of patients in whom therapeutic drug monitoring is ongoing through a research protocol. METHODS: In a multicenter study, genotypic analyses at two MDR1 loci, C3435T and G2677T, were performed by a real-time polymerase chain reaction method using DNA from 103 patients categorized as substance users or nonusers on atazanavir or lopinavir as the primary antiretrovirals. Allelic frequencies were determined as a function of racial/ethnic background, substance use status and trough concentrations of atazanavir and lopinavir. RESULTS: The C/T and G/T alleles at the MDR1 C3435T and G2677T loci were equally frequent in the Caucasian population, but the wild-type alleles were more prevalent in the African-American population (59% homozygous [CC] and 32% heterozygous [CT] for C3435T; 80% homozygous [GG] and 16% heterozygous [GT] for G2677T). The frequencies in the Hispanic population were 46% CC and 38% CT for C3435T, and 58% GG and 38% GT for G2677T. No significant differences were seen in allele frequencies for MDR1 polymorphisms in substance user versus nonuser groups. Trough plasma concentrations of atazanavir or lopinavir were not correlated with the variant T allele. CONCLUSIONS: These data confirm the higher prevalence of wild-type alleles of the MDR1 gene in African-Americans and the linkage disequilibrium between C3435T and G2677T loci. The T allele at the MDR1 C3435T and G2677T loci was not associated with higher atazanavir or lopinavir trough concentrations.

RESUMEN

BACKGROUND: Amdoxovir (2,6-diaminopurine dioxolane; DAPD) is a nucleoside reverse transcriptase inhibitor (NRTI) of human immunodeficiency virus-1 (HIV-1) with activity against wild-type and NRTI-resistant viruses. METHODS: ACTG A5118 assessed the antiretroviral activity and safety of DAPD (300 mg orally, twice daily) versus placebo in combination with enfuvirtide (ENF) plus an optimized background (OB) regimen in subjects with failure of two or more antiretroviral (ARV) regimens. The primary endpoints for comparison were time-averaged area under the curve minus baseline (AAUCMB) of plasma HIV-1 RNA concentration at 24 weeks and time to first serious (DAIDS toxicity table Grade > or = 3) adverse event (AE). An unplanned interim review recommended closing enrollment because the study was unlikely to demonstrate a difference between arms. The 18 subjects on study, nine in each arm, were unblinded and allowed to continue study treatment through 48 weeks. RESULTS: Intention-to-treat analysis showed the median AAUCMB was -0.9 log10 copies/mL (95% CI = -2.2, -.0.1) in the DAPD arm and -0.9 log10 copies/ml (95% CI = -1.1, -0.1) in the placebo arm (P = 0.69). Median CD4+ T-cell increase was 79 cells/mm3 (95% CI =1, 115) in the DAPD arm and 60 (95% CI =1, 101) in the placebo arm (P = 0.45). Time to first serious AE did not differ between arms (P = 0.91). Mild decreases of creatinine clearance were observed with similar frequency between arms; no subject developed lens opacities. CONCLUSIONS: Addition of DAPD to ENF plus OB in advanced subjects with highly resistant virus appeared safe, but did not add statistically significant antiretroviral activity at 24 weeks in this small study.

RESUMEN

BACKGROUND: It is unclear whether therapy for human immunodeficiency virus type 1 (HIV-1) should be initiated with a four-drug or two sequential three-drug regimens. METHODS: In this multicenter trial we compared initial therapy involving four-drug regimens containing efavirenz and nelfinavir in combination with either didanosine and stavudine or zidovudine and lamivudine with therapy involving two consecutive three-drug regimens the first of which contained either efavirenz or nelfinavir. RESULTS: A total of 980 subjects were followed for a median of 2.3 years. There was no significant difference in the occurrence of regimen failures between the group that received the four-drug regimen containing didanosine, stavudine, nelfinavir, and efavirenz and the groups that received the three-drug regimens beginning with didanosine, stavudine, and nelfinavir (hazard ratio for regimen failure, 1.24) or didanosine, stavudine, and efavirenz (hazard ratio, 1.01). There was no significant difference between the group that received the four-drug regimen containing zidovudine, lamivudine, nelfinavir, and efavirenz and the groups that received the three-drug regimens beginning with zidovudine, lamivudine, and nelfinavir (hazard ratio, 1.06) or zidovudine, lamivudine, and efavirenz (hazard ratio, 1.45). A four-drug regimen was associated with a longer time to the first regimen failure than the three-drug regimens containing didanosine, stavudine, and nelfinavir (hazard ratio for a first regimen failure, 0.55); didanosine, stavudine, and efavirenz (hazard ratio, 0.63); or zidovudine, lamivudine, and nelfinavir (hazard ratio, 0.49), but not the three-drug regimen containing zidovudine, lamivudine, and efavirenz (hazard ratio, 1.21). CONCLUSIONS: There was no significant difference in the duration of successful HIV-1 treatment between a single four-drug regimen and two consecutive three-drug regimens. Among these treatment strategies, initiating therapy with the three-drug regimen of zidovudine, lamivudine, and efavirenz is the optimal choice.

RESUMEN

BACKGROUND: The classical triad of Job's syndrome (Hyper-IgE syndrome), a congenital immunodeficiency disorder, includes recurrent "cold" abscesses, pneumonias and extreme elevations of the serum IgE concentration. CASE REPORT: A 49-year-old HIV-1 infected patient with a viral load of 268,852 copies/ml plasma and a CD4+ T lymphocyte concentration of 2 cells/microliter blood was admitted to our clinic for antibiotic therapy and incision and drainage of several large abscesses. The patient suffered for approximately 5 years from recurrent pneumonias, abscesses and multiple allergies. The serum IgE level was over 100-fold elevated and, after analysis of archived serum samples, had not been influenced by fluctuations in the plasma viral load or changes in the CD4+ T lymphocyte concentration in previous years. No stigmata of Job's syndrome were present prior to the patient's HIV-1 infection. Observations on other patients with AIDS and recurrent abscesses suggest that in these patients hyperimmunoglobulinemia E is related to a cytokine class switch from a TH1 to a TH2 profile as CD4+ T lymphocytes are depleted. CONCLUSIONS: Following CD4+ T lymphocyte depletion, it has been rarely documented that HIV-1 infected patients may develop clinical symptoms and a hyperimmunoglobulinemia E, similar to patients with the congenital immunodeficency of Job's syndrome.
