Abstract
Background: Long-acting injectable (LAI) cabotegravir/rilpivirine (CAB/RPV) extends dosing intervals from daily to every 8 weeks. Equitable implementation requires anticipating and addressing barriers to use. We described LAI-CAB/RPV eligibility and initiation among persons with HIV (PWH) receiving care at a Southeastern US academic medical center. Methods: We included PWH ≥18 years, in care 01/01/2020-12/31/2021, and participating in the UNC CFAR HIV Clinical Cohort. We characterized LAI-CAB/RPV eligibility, compared those with and without recent detectable viral load (VL), and described clinical outcomes on LAI-CAB/RPV. Results: Among 1672 PWH, 425 (25.4%) had LAI-CAB/RPV drug-resistance. Among 1238 LAI-eligible PWH, 8.9% had detectable VL. Median age was 53 (interquartile range 40, 61), 54.6% were non-Hispanic Black, and 73.6% male. Over one-third lived >50 miles from clinic, one-fifth were uninsured, and 7.4% reported hazardous alcohol use. Gaps in care (prior 12-month) were more common among PWH with detectable VL versus suppressed (23.1% vs 13.9%, p = 0.03). 6/47 initiated LAI-CAB/RPV had detectable VL prior to injection; >95% sustained suppression and those with detectable VL had a rapid decline in viremia. Conclusions: Three-quarters of PWH were eligible for LAI-CAB/RPV, but equitable implementation may require addressing challenges such as distance to care, inconsistent care engagement, and other comorbid conditions, particularly for PWH with viremia.

Food Insecurity Prevalence and Risk Factors among Persons with HIV in a Southeastern US Clinical Care Setting. AIDS Behav 2024:10.1007/s10461-024-04497-7. [PMID: 39266889 DOI: 10.1007/s10461-024-04497-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/29/2024] [Indexed: 09/14/2024]
Abstract
Food insecurity (FI) is associated with adverse health outcomes for persons with HIV (PWH). Little is known about FI among PWH in southern or non-urban settings. We examined FI prevalence, risk factors, and access to services in a southeastern HIV clinic. Among PWH in the UNC CFAR HIV Clinical Cohort who were screened for FI as part of HIV care between 2021 and 2022, we estimated unadjusted prevalence ratios (PRs) comparing the probability of reporting FI by demographic and clinical characteristics. The 479 PWH screened for FI were 65% cisgender men, 62% non-Hispanic Black PWH, a median of 54 years old (IQR 41-62), and 93% with an HIV viral load (VL) < 200 copies/mL. FI prevalence was 36.3% (95% CI 32.3%-40.9%). Cisgender women and transgender adults were more likely to report FI than cisgender men (PRs 1.24 [95% CI 0.97-1.59] and 2.03 [1.32-3.12], respectively). Compared with White PWH, the PR was 1.71 (1.20-2.42) for Black and 2.44 (1.56-3.82) for Hispanic PWH. The PR was 1.42 (0.98-2.05) for PWH with VL ≥ 200 versus < 200 copies/mL. Having no or public versus private health insurance was also associated with FI. PWH with FI had a high prevalence of comorbidities including hypercholesterolemia (49%) and hypertension (48%), though these were not associated with FI. Almost half of PWH with FI were not accessing a food pantry or nutrition assistance program. Identifying FI in PWH is critical as FI is common and may contribute to viral non-suppression, poor comorbidity control, and gender and racial/ethnic health disparities in PWH.

Abstract
In this viewpoint, we discuss retention in care for people with human immunodeficiency virus (HIV) and call into question the methodology used to characterize retention, as well as the definitions themselves. Optimal retention for people with HIV (PWH) is defined in multiple ways by major healthcare leaders in the United States, typically focusing on appointment attendance or laboratory work. Yet, these definitions rely on in-person encounters, an approach to care that is becoming less common due to the rise of telehealth visits, particularly in light of the coronavirus disease 2019 pandemic. Our recent work showed that relying on electronic health records to identify PWH who were not retained in care not only failed to capture the nuances of modern HIV medical treatment engagement, but also led to misidentification of patients' retention status due to limitations in the record system. As such, we recommend a reevaluation of how HIV medical care retention is defined and reported.

Abstract
Hypertension management outcomes in people with HIV (PWH) are not well characterized, despite high hypertension burden. We assessed hypertension prevalence, incidence, treatment, and outcomes among patients with HIV at a clinical center in the southeastern US, from 2014 to 2019. To identify characteristics associated with treatment and outcomes, we estimated adjusted risk ratios (aRR) and 95% confidence intervals (CI). Among 2274 patients, 72% were cisgender men, 56% non-Hispanic Black, median age 47 years, 48% MSM, 12% had CD4 cell count <200 cells/μl, 72% HIV RNA level <400 copies/mL and 39% prevalent hypertension. Hypertension incidence rate was 6.3/100 person-years (95% CI, 5.6-7.0). Among incident hypertension cases (n = 275), 16% (95% CI, 11-20) initiated an antihypertensive within one year. Compared to non-Hispanic white patients, Hispanic (aRR, 6.68; 95% CI, 1.50-29.74) and non-Hispanic Black patients (aRR, 2.18; 95% CI, 0.91-5.24) were more likely to initiate an antihypertensive. Among patients initiating an antihypertensive (n = 178), 63% (95% CI 56-70) experienced blood pressure control within one year. Patients with HIV experienced a high burden of hypertension with notable delays in antihypertensive initiation, as well as gaps in achieving blood pressure control, highlighting opportunities for interventions designed to minimize delays in controlling hypertension in this vulnerable population.

Characterizing the neighborhood risk environment in multisite clinic-based cohort studies: A practical geocoding and data linkages protocol for protected health information. PLoS One 2022; 17:e0278672. [PMID: 36580446 PMCID: PMC9799318 DOI: 10.1371/journal.pone.0278672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 11/21/2022] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Maintaining patient privacy when geocoding and linking residential address information with neighborhood-level data can create challenges during research. Challenges may arise when study staff have limited training in geocoding and linking data, or when non-study staff with appropriate expertise have limited availability, are unfamiliar with a study's population or objectives, or are not affordable for the study team. Opportunities for data breaches may also arise when working with non-study staff who are not on-site. We detail a free, user-friendly protocol for constructing indices of the neighborhood risk environment during multisite, clinic-based cohort studies that rely on participants' protected health information. This protocol can be implemented by study staff who do not have prior training in Geographic Information Systems (GIS) and can help minimize the operational costs of integrating geographic data into public health projects. METHODS This protocol demonstrates how to: (1) securely geocode patients' residential addresses in a clinic setting and match geocoded addresses to census tracts using Geographic Information System software (Esri, Redlands, CA); (2) ascertain contextual variables of the risk environment from the American Community Survey and ArcGIS Business Analyst (Esri, Redlands, CA); (3) use geoidentifiers to link neighborhood risk data to census tracts containing geocoded addresses; and (4) assign randomly generated identifiers to census tracts and strip census tracts of their geoidentifiers to maintain patient confidentiality. RESULTS Completion of this protocol generates three neighborhood risk indices (i.e., Neighborhood Disadvantage Index, Murder Rate Index, and Assault Rate Index) for patients' coded census tract locations. CONCLUSIONS This protocol can be used by research personnel without prior GIS experience to easily create objective indices of the neighborhood risk environment while upholding patient confidentiality. Future studies can adapt this protocol to fit their specific patient populations and analytic objectives.

Abstract
Background Medically vulnerable individuals are at increased risk of acquiring multidrug-resistant Enterobacterales (MDR-E) infections. People with HIV (PWH) experience a greater burden of comorbidities and may be more susceptible to MDR-E due to HIV-specific factors. Methods We performed an observational study of PWH participating in an HIV clinical cohort and engaged in care at a tertiary care center in the Southeastern United States from 2000 to 2018. We evaluated demographic and clinical predictors of MDR-E by estimating prevalence ratios (PRs) and employing machine learning classification algorithms. In addition, we created a predictive model to estimate risk of MDR-E among PWH using a machine learning approach. Results Among 4734 study participants, MDR-E was isolated from 1.6% (95% CI, 1.2%-2.1%). In unadjusted analyses, MDR-E was strongly associated with nadir CD4 cell count ≤200 cells/mm3 (PR, 4.0; 95% CI, 2.3-7.4), history of an AIDS-defining clinical condition (PR, 3.7; 95% CI, 2.3-6.2), and hospital admission in the prior 12 months (PR, 5.0; 95% CI, 3.2-7.9). With all variables included in machine learning algorithms, the most important clinical predictors of MDR-E were hospitalization, history of renal disease, history of an AIDS-defining clinical condition, CD4 cell count nadir ≤200 cells/mm3, and current CD4 cell count 201-500 cells/mm3. Female gender was the most important demographic predictor. Conclusions PWH are at risk for MDR-E infection due to HIV-specific factors, in addition to established risk factors. Early HIV diagnosis, linkage to care, and antiretroviral therapy to prevent immunosuppression, comorbidities, and coinfections protect against antimicrobial-resistant bacterial infections.

Abstract
Black/African American (Black) versus White persons are unequally burdened by human immunodeficiency virus (HIV) in the United States. Structural factors can influence social determinants of health, key components in reducing HIV-related health inequality by race. This analysis examined HIV care outcomes among Black and White persons with diagnosed HIV (PWDH) in relation to three structural factors: racial redlining, Medicaid expansion, and Ryan White HIV/AIDS Program (RWHAP) use. Using National HIV Surveillance System, U.S. Census, and Home Mortgage Disclosure Act data, we examined linkage to HIV care and viral suppression (i.e., viral load < 200 copies/mL) in relation to the structural factors among 12,996 Black and White PWDH with HIV diagnosed in 2017/alive at year-end 2018, aged ≥ 18 years, and residing in 38 U.S. jurisdictions with complete laboratory data, geocoding, and census tract-level redlining indexes. Compared to White PWDH, a lower proportion of Black PWDH were linked to HIV care within 1 month after diagnosis and were virally suppressed in 2018. Redlining was not associated with the HIV care outcomes. A higher prevalence of PWDH residing (v. not residing) in states with Medicaid expansion were linked to HIV care ≤ 1 month after diagnosis. A higher prevalence of those residing (v. not residing) in states with > 50% of PWDH in RWHAP had viral suppression. Direct exposure to redlining was not associated with poor HIV care outcomes. Structural factors that reduce the financial burden of HIV care and improve care access like Medicaid expansion and RWHAP might improve HIV care outcomes of PWDH.

Abstract
Background People with HIV (PWH) may be at increased risk for MDR Enterobacterales (MDR-E) infection or colonization, relative to individuals without HIV, due to a greater burden of comorbidities as well as HIV-related intestinal inflammation and microbiota alterations. Objectives To characterize antibiotic susceptibility of enteric Enterobacterales and risk factors for antimicrobial-resistant bacterial infections in a sample of PWH attending routine clinic visits. Methods Participants provided self-administered rectal swabs and completed questionnaires regarding healthcare, travel and occupational exposures for the prior 12 months. Rectal samples were processed to identify Enterobacterales species, and susceptibility testing was performed. Results Among 82 participants, 110 Enterobacterales isolates were obtained. Non-susceptibility was common for penicillins, sulphonamides and first-generation cephalosporins. MDR-E was present in 20% of participants. HIV-related characteristics, including current or nadir CD4 cell count, viral suppression, or AIDS-defining clinical conditions, were not associated with MDR-E. Conclusions MDR-E colonization is common in this population of PWH. Further research evaluating risk factors for MDR-E in PWH may inform infection prevention approaches to better protect at-risk populations from these difficult-to-treat infections.

Abstract
Understanding resilience in relation to HIV-related outcomes may help address racial/ethnic disparities, however, significant gaps in its measurement preclude in-depth study. Thus, this research aims to develop and evaluate the psychometric properties of long and short forms of the Multilevel Resilience Resource Measure for African American/Black Adults Living with HIV. To develop the items, we conducted a mixed methods study (N = 48) and reviewed published resilience measures. We completed content validity index analyses to ensure the items reflected the resilience construct. Next, we conducted 20 cognitive interviews and a field survey (N = 400). The long and short forms demonstrated acceptable to excellent psychometric properties based on factorial validity, internal consistency and convergent validity and on measurement invariance (conducted for the short form only). These measures provide a comprehensive framework to examine resilience and HIV-related outcomes and can inform resilience-building interventions to reduce racial and ethnic health disparities.

Abstract
BACKGROUND Multidrug-resistant Enterobacterales (MDR-E) are important pathogens. People with human immunodeficiency virus (HIV) may be at greater risk for MDR-E infection given relatively high antibiotic exposure and burden of comorbidities. METHODS Analyses were conducted using data collected on 36,521 patients in a healthcare system in North Carolina, who had at least 1 clinical culture with growth of an Enterobacterales species from 2000-2018; 440 were people with HIV infection (PWH). We used generalized linear models to estimate prevalence ratios and differences contrasting patients with and without HIV for resistance to individual antibiotic classes, as well as MDR-E. We assessed trends in prevalence over time by calculating the 5-year moving average and fitting restricted cubic spline models. RESULTS The overall prevalence of MDR-E was higher among PWH (21.5% [95% CI: 18.2%-25.1%]) versus patients without HIV (16.5% [95% CI: 16.2%-16.9%], with an adjusted prevalence ratio of 1.38 (95% CI: 1.14-1.65). PWH had higher rates of antimicrobial resistance than patients without HIV for all antibiotic classes analyzed, including penicillins, penicillin/beta-lactamase inhibitor combinations, and sulfonamides. MDR-E prevalence was 3 to 10 percentage points higher among PWH than patients without HIV throughout the study period based on the 5-year moving average. CONCLUSION In a large clinical study population in the southeastern US from 2000-2018, the prevalence of antibacterial resistance among Enterobacterales was consistently higher among PWH than patients without HIV. These data highlight the importance of identifying and mitigating the factors contributing to antimicrobial resistance in PWH, given the potential clinical consequences of these resistant pathogens.

Abstract
Resilience may help people living with HIV (PLWH) overcome adversities to disease management. This study identifies multilevel resilience resources among African American/Black (AA/B) PLWH and examines whether resilience resources differ by demographics and neighborhood risk environments. We recruited participants and conducted concept mapping at two clinics in the southeastern United States. Concept Mapping incorporates qualitative and quantitative methods to represent participant-generated concepts via two-dimensional maps. Eligible participants had to attend ≥ 75% of their scheduled clinic appointments and did not have ≥ 2 consecutive detectable HIV-1 viral load measurements in the past 2 years. Of the 85 AA/B PLWH who were invited, forty-eight participated. Twelve resilience resource clusters emerged-five individual, two interpersonal, two organizational/policy and three neighborhood level clusters. There were strong correlations in cluster ratings for demographic and neighborhood risk environment comparison groups (r ≥ 0.89). These findings could inform development of theories, measures and interventions for AA/B PLWH.

Abstract
Infectious disease surveillance is often case-based, focused on people diagnosed and their contacts in a predefined time window, and treated as independent across infections. Network analysis of partners and contacts joining multiple investigations and infections can reveal social or temporal trends, providing opportunities for epidemic control within broader networks. We constructed a sociosexual network of all HIV and early syphilis cases and contacts investigated among residents of 11 contiguous counties in North Carolina over a two-year period (2012-2013). We anchored the analysis on new HIV diagnoses ("indexes"), but also included nodes and edges from syphilis investigations that were within the same network component as any new HIV index. After adding syphilis investigations and deduplicating people included in multiple investigations (entity resolution), the final network comprised 1470 people: 569 HIV indexes, 700 contacts to HIV indexes who were not also new cases themselves, and 201 people who were either indexes or contacts in eligible syphilis investigations. Among HIV indexes, nearly half (48%; n = 273) had no located contacts during single-investigation contact tracing, though 25 (9%) of these were identified by other network members and thus not isolated in the final multiple investigation network. Constructing a sociosexual network from cases and contacts across multiple investigations mitigated some effects of unobserved partnerships underlying the HIV epidemic and demonstrated the HIV and syphilis overlap in these networks.

Abstract
This pilot study assessed feasibility of computer-assisted electronic medical record (EMR) abstraction to ascertain coronary heart disease (CHD) event hospitalizations. We included a sample of 87 hospitalization records from participants the University of North Carolina (UNC) site of the Women's Interagency HIV Study (WIHS) and UNC Center for AIDS Research (CFAR) HIV Clinical Cohort who were hospitalized within UNC Healthcare System from July 2004 to July 2015. We compared a computer algorithm utilizing diagnosis/procedure codes, medications, and cardiac enzyme levels to adjudicate CHD events [myocardial infarction (MI)/coronary revascularization] from the EMR to standardized manual chart adjudication. Of 87 hospitalizations, 42 were classified as definite, 25 probable, and 20 non-CHD events by manual chart adjudication. A computer algorithm requiring presence of ≥1 CHD-related International Classification of Diseases, 9th Revision (ICD-9)/Current Procedural Terminology (CPT) code correctly identified 24 of 42 definite (57%), 29 of 67 probable/definite CHD (43%), and 95% of non-CHD events; additionally requiring clinically defined cardiac enzyme levels or administration of MI-related medications correctly identified 55%, 42%, and 95% of such events, respectively. Requiring any one of the ICD-9/CPT or cardiac enzyme criteria correctly identified 98% of definite, 97% of probable/definite CHD, and 85% of non-CHD events. Challenges included difficulty matching hospitalization dates, incomplete diagnosis code data, and multiple field names/locations of laboratory/medication data. Computer algorithms comprising only ICD-9/CPT codes failed to identify a sizable proportion of CHD events. Using a less restrictive algorithm yielded fewer missed events but increased the false-positive rate. Despite potential benefits of EMR-based research, there remain several challenges to fully computerized adjudication of CHD events.

Abstract
BACKGROUND AND OBJECTIVES Access to kidney transplantation requires a referral to a transplant center for medical evaluation. Prior research suggests that the distance that a person must travel to reach a center might be a barrier to referral. We examined whether a shorter distance from patients' residence to a transplant center increased the likelihood of referral and initiating the transplant evaluation once referred. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Adults who began treatment for ESKD at any Georgia, North Carolina, or South Carolina dialysis facility from 1/1/2012 to 12/31/2015 were identified from the US Renal Data System. Referral (within 1 year of dialysis initiation) and evaluation initiation (within 6 months of referral) data were collected from all nine transplant centers located in that region. Distance was categorized as <15, 15-30, 31-60, 61-90, and >90 miles from the center of a patient's residential zip code to the nearest center. We used multilevel, multivariable-adjusted logistic regression to quantify the association between distance with referral and evaluation initiation. RESULTS Among 27,250 adult patients on incident dialysis, 9582 (35%) were referred. Among those referred, 58% initiated evaluation. Although patients who lived farther from a center were less likely to be referred, distance was not statistically significantly related to transplant referral: adjusted odds ratios of 1.08 (95% confidence interval, 0.96 to 1.22), 1.07 (95% confidence interval, 0.95 to 1.22), 0.96 (95% confidence interval, 0.84 to 1.10), and 0.87 (95% confidence interval, 0.74 to 1.03) for 15-30, 31-60, 61-90, and >90 miles, respectively, compared with <15 miles (P trend =0.05). There was no statistically significant association of distance and evaluation initiation among referred patients: adjusted odds ratios of 1.14 (95% confidence interval, 0.97 to 1.33), 1.12 (95% confidence interval, 0.94 to 1.35), 1.04 (95% confidence interval, 0.87 to 1.25), and 0.89 (95% confidence interval, 0.72 to 1.11) for 15-30, 31-60, 61-90, and >90 miles, respectively, compared with <15 miles (P trend =0.70). CONCLUSIONS Distance from residence to transplant center among patients undergoing long-term dialysis in the southeastern United States was not associated with increased likelihood of referral and initiating transplant center evaluation.

Abstract
The prevalence of opioid misuse by people living with HIV (PLWH) during the current US opioid epidemic has not been fully described. Among a cohort of persons engaged in HIV care in North Carolina, we examined the prevalence of and risk factors for opioid misuse, defined as self-reported "street" opioid use (e.g., heroin) or nonmedical prescription opioid use on a patient reported outcomes survey. Recent (past three-month) opioid misuse among 1,440 PLWH in care 2012-2017 was 2% (95% CI 2-3%) and lifetime misuse 15% (13-16%). Persons reporting lifetime or recent misuse more commonly had hepatitis C and reported injecting drugs. In multivariable logistic regression models, male-to-male sexual contact was inversely associated with recent or lifetime misuse. White/non-Hispanic race/ethnicity was associated with lifetime misuse and CD4 count and viral load were not associated with opioid misuse. Among 32 persons reporting recent misuse, 81% had a contemporaneous viral load <50 copies/mL. In this cohort of PLWH engaged in care, recent opioid misuse prevalence was similar to general population estimates. Assessments of opioid misuse among PLWH not in care are urgently needed to fully characterize the impact of opioids on all PLWH.

Abstract
BACKGROUND We estimated the effect of initiating virologically suppressive antiretroviral therapy (ART) during acute HIV infection versus chronic HIV infection (AHI vs. CHI) on CD4/CD8 ratio normalization. SETTING A prospective clinical cohort study. METHODS We included patients initiating ART with AHI and CHI between 2000 and 2015 and compared time from ART initiation to the first normal CD4/CD8 ratio (defined as CD4/CD8 ≥1) using Kaplan-Meier curves and multivariable Cox proportional hazards models. Patient time was censored at virologic failure, lost to follow-up, or death. We also characterized CD4, CD8, and CD4/CD8 trajectories over the first 3 years of ART. RESULTS The 1198 patients were 27% female and 60% African American, with a median age of 37 years (interquartile range 28-47) at ART initiation. The 83 AHI patients were more likely male, younger, and of white race, than CHI patients. After 2 years of suppressive ART, 70% of AHI patients achieved a normal CD4/CD8 ratio, compared to 6%-38% of CHI patients, with greater likelihood of normalization at higher baseline CD4 counts. Time to normalization was shortest among AHI patients, followed by CHI patients with higher baseline CD4. The adjusted hazard ratio for time to normalization for AHI patients compared to CHI patients with baseline CD4 >350 was 4.33 (95% CI: 3.16 to 5.93). Higher baseline CD4/CD8 ratio was also associated with time to normalization (adjusted hazard ratio 1.54; 1.46, 1.63, per 0.1 increase in ratio). CONCLUSIONS Initiating ART during AHI at higher baseline CD4 cell counts and CD4/CD8 ratios was associated with shorter time to CD4/CD8 ratio normalization.

Abstract
The literature recognizes six measures of retention in care, an integral component of the HIV Continuum of Care. Given prior research showing that different retention measures are differentially associated with HIV health outcomes (e.g., CD4 count and viral suppression), we hypothesized that different groups of people living with HIV (PLWH) would also have differential retention outcomes based on the retention measure applied. We conducted a cross-sectional analysis of multisite patient-level medical record data (n = 10,053) from six academically-affiliated HIV clinics using six different measures of retention. Principal component analysis indicated two distinct retention constructs: kept-visit-measures and missed-visit measures. Although black (compared to white) PLWH had significantly poorer retention on the three missed-visit measures, race was not significantly associated with any of the three kept-visit measures. Males performed significantly worse than females on all kept-visit measures, but sex differences were not observed for any missed-visit retention measures. IDU risk transmission group and younger age were associated with poorer retention on both missed- and kept-visit retention measures. Missed- and kept-visit measures may capture different aspects of retention, as indicated in the observed differential associations among race, sex, age, and risk transmission group. Multiple measures are needed to effectively assess retention across patient subgroups.

Abstract
OBJECTIVE The aim of this study was to evaluate postpartum HIV care outcomes. DESIGN A prospective clinical cohort of women with HIV and a live birth at the University of North Carolina, 1996-2014. METHODS We estimated two stages of the HIV care continuum in the first 24 months postpartum: care retention (at least two visits per year, ≥90 days apart) and viral suppression (HIV RNA < 400 copies/ml). Multivariable models were fit using logistic regression. RESULTS Among 1416 women, 141 experienced a live birth at a median age of 28 years, with 74% virally suppressed at delivery. Among all women, 48% were retained in care and 25% maintained viral suppression for the first 24 months postpartum. Among women with available HIV RNA measures, 42% were suppressed at 24 months. HIV care retention estimates were stable across calendar years, but viral suppression rates at 24 months postpartum, among women with available HIV RNA measures, increased from 33 to 67% from 1996-2001 to 2009-2014 (P = 0.04). Being at least 30 years old was positively, and receiving less than 12 weeks of antenatal antiretroviral therapy was negatively, associated with HIV care retention at 24 months postpartum [adjusted odds ratio (AOR): 2.41, 95% confidence interval (95% CI): 1.09-5.29 and AOR: 0.27, 95% CI: 0.08-0.86]. Older maternal age and viral suppression at delivery were both positively associated with virologic suppression at 24 months postpartum (AOR: 2.52, CI: 1.02-6.22, and AOR: 6.42 CI: 1.29-31.97, respectively). CONCLUSION HIV care continuum outcomes decrease substantially postpartum, with younger women and those with less antenatal HIV care less likely to successfully remain engaged in HIV care following childbirth.

Abstract
OBJECTIVE To estimate the prevalence of HIV drug resistance over time and identify risk factors for multiclass resistance. DESIGN Prospective clinical cohort of HIV-infected patients at the University of North Carolina. METHODS Among antiretroviral therapy (ART)-experienced patients in care 2000-2016, we estimated annual prevalences of cumulative resistance, defined as at least one major mutation by drug class. Clinical data and multiple imputation were used when genotypic data were missing, and mutations were carried forward in time. We estimated resistance odds ratios comparing characteristics of patients in care in 2016. RESULTS A total of 3682 patients contributed 23 169 person-years. Prevalence of at least one major resistance mutation, irrespective of viral suppression, peaked in 2005 with 49% (95% confidence interval 46, 52) and decreased to 38% (35, 40) in 2016. Resistance to nucleoside reverse transcriptase inhibitors, protease inhibitors, and nonnucleoside reverse transcriptase inhibitors also peaked in 2005-2007 and decreased to 28 (26, 31), 14 (12, 16), and 27% (24, 29) in 2016, respectively. In 2016, prevalence of integrase strand transfer inhibitor (INSTI) resistance was 2% (1, 3) and triple-class resistance 10% (9, 12). Over the study period, cumulative resistance was frequent among patients with detectable viremia, but uncommon among patients initiating ART post-2007. Among 1553 patients in care in 2016, ART initiation at an older age, with an INSTI, and with higher CD4 cell counts were associated with resistance to fewer or no classes. CONCLUSION Prevalence of resistance to older ART classes has decreased in the last 10 years in this clinical cohort, whereas INSTI resistance has increased but remained very low. Patients with viremia continue to have a high burden of resistance even if they initiated ART recently.

Abstract
Antiretroviral (ARV) adherence has largely been considered from the perspective of an individual's behavior with less attention given to potential structural causes for lapses in treatment, such as the cost of medications and care. HIV medication expense is typically covered by third party payers. However, private insurance premiums and deductibles may rise, or policies terminated such as with a change in employment. Likewise, a patient's eligibility for publicly funded coverage like state AIDS Drug Assistance Programs (ADAP) or Medicaid can also be lost. We conducted a one-time survey of a sample of 300 patients receiving HIV care at a single large academic center in the south of United States to examine lapses in HIV therapy due to financial reasons. We found that during the prior year, financial issues including medication cost or coverage led to a lapse in ARVs in 10% (n = 31) of participants. However, of the 42% (n = 125) participants who had been enrolled in ADAP at any time during the prior year, 21% (n = 26) reported an ARV lapse due to problems with ADAP or medication cost. Respondents cited ADAP's required semi-annual renewal process and other administrative issues as the cause of ARV lapses. The median duration of missed ARVs was 2 weeks (range of <1-23 weeks). Non-HIV medication and transportation to and from clinic costs were also identified as financial burdens to care by respondents. In conclusion, although conducted at a single medical center and one state, this study suggests that a significant minority of HIV-infected patients encounter financial barriers to ARV access, and this is paradoxically more common among those enrolled in the state ADAP. Streamlining, supporting, and simplifying ADAP renewal procedures will likely reduce lapses in ARV adherence and persistence.

Abstract
BACKGROUND Delaying HIV care initiation may lead to greater morbidity, mortality, and further HIV transmission. Rural residence may be associated with delayed diagnosis and linkage to care, with negative clinical outcomes. OBJECTIVE To examine the association between rural patient residence and CD4 cell count at HIV care initiation in a large HIV clinical cohort in the Southeastern United States. METHODS We included HIV-infected patients who initiated care between 1996 and 2012 with a geocodable address and no previous history of HIV clinical care. Patient residence was categorized as urban or rural using United States Department of Agriculture Rural Urban Commuting Area codes. Multivariable linear regression models were fit to estimate the association between patient residence and CD4 cell count at HIV care initiation. RESULTS Among 1396 patients who met study inclusion criteria, 988 had a geocodable address. Overall, 35% of patients resided in rural areas and presented to HIV care with a mean CD4 cell count of 351 cells/mm (SD, 290). Care initiation mean CD4 cell counts increased from 329 cells/mm (SD, 283) in 1996-2003 to 391 cells/mm (SD, 292) in 2008-2012 (P = 0.006). Rural in comparison with urban patients presented with lower CD4 cell counts with an unadjusted and adjusted mean difference of -48 cells/mm [95% confidence interval, -86 to -10) and -37 cells/mm (95% confidence interval: -73 to -2), respectively, consistently observed across calendar years. CONCLUSIONS HIV care initiation at low CD4 cell counts was common in this Southeastern US cohort and more common among rural area residents.

Abstract
BACKGROUND Initiating antiretroviral therapy (ART) early improves clinical outcomes and prevents transmission. Guidelines for first-line therapy have changed with the availability of newer ART agents. In this study, we compared persistence and virologic responses with initial ART according to the class of anchor agent used. SETTING An observational clinical cohort study in the Southeastern United States. METHODS All HIV-infected patients participating in the UNC Center for AIDS Research Clinical Cohort (UCHCC) and initiating ART between 1996 and 2014 were included. Separate time-to-event analyses with regimen discontinuation and virologic failure as outcomes were used, including Kaplan-Meier survival curves and adjusted Cox proportional hazards models. RESULTS One thousand six hundred twenty-four patients were included (median age of 37 years at baseline, 28% women, 60% African American, and 28% white). Eleven percent initiated integrase strand transfer inhibitor (INSTI), 33% non-nucleoside reverse transcriptase inhibitor (NNRTI), 20% boosted protease inhibitor, 27% other, and 9% NRTI only regimens. Compared with NNRTI-containing regimens, INSTI-containing regimens had an adjusted hazard ratio of 0.49 (95% confidence interval, 0.35 to 0.69) for discontinuation and 0.70 (95% confidence interval, 0.46 to 1.06) for virologic failure. All other regimen types were associated with increased rates of discontinuation and failure compared with NNRTI. CONCLUSIONS Initiating ART with an INSTI-containing regimen was associated with lower rates of regimen discontinuation and virologic failure.

Abstract
Longitudinal opioid prescription use is unknown among HIV-infected patients. Group-based trajectory modeling followed by multinomial logistic regression was used to identify distinct trajectories and their association with baseline characteristics among 1239 HIV-infected UNC CFAR HIV Clinical Cohort participants, 2000-2014. Three trajectories were identified: (1) 72% never/sporadic opioid use (referent group), (2) 11% episodic use (associated with female sex, depression, drug-related diagnoses, antiretroviral therapy use, and undetectable HIV RNA), and (3) 16% chronic use (associated with older age, female sex, and mental health diagnoses). Overall, opioid prescription decreased substantially with longer time in HIV care among both episodic and chronic users.

Abstract
BACKGROUND Persons infected with human immunodeficiency virus (HIV) are at higher risk for major cardiovascular disease (CVD) events than uninfected persons. Understanding the epidemiology of major traditional CVD risk determinants, particularly hypertension, in this population is needed. METHODS The study population included HIV-infected patients participating in the UNC CFAR HIV Clinical Cohort from 1996 to 2013. Annual incidence rates of hypertension were calculated. Multivariable Poisson models were fit to identify factors associated with incident hypertension. RESULTS 3141 patients contributed 21 956 person-years (PY) of follow-up. Overall, 57% patients were black, 28% were women, and the median age was 35 years. Hypertension age-standardized incidence rates increased from 1.68 cases per 100 PYs in 1996 to 5.35 cases per 100 PYs in 2013 (P < .001). In adjusted analyses, hypertension rates were higher among obese patients (incidence rate ratio [IRR] 1.70, 95% confidence interval [CI], 1.43-2.02), and those with diabetes mellitus (IRR 1.44, 95% CI, 1.14-1.83) and renal insufficiency (IRR 1.36, 95% CI, 1.16-1.61), but lower among patients with a CD4 nadir of ≥500 cells/mm(3) (IRR 0.73, 95% CI, .53-1.01). CONCLUSIONS The incidence of hypertension increased from 1996 to 2013, alongside increases in traditional hypertension risk determinants. Notably, HIV-related immunosuppression and ongoing viral replication may contribute to an increased hypertension risk. Aggressive CVD risk factor management, early HIV diagnosis, linkage to care, antiretroviral therapy initiation, and durable viral suppression, will be important components of a comprehensive primary CVD prevention strategy in HIV-infected persons.

Abstract
Sequencing of a bulk polymerase chain reaction (PCR) product to identify drug resistance mutations informs antiretroviral therapy selection but has limited sensitivity for minority variants. Alternatively, deep sequencing is capable of detecting minority variants but is subject to sequencing errors and PCR resampling due to low input templates. We screened for resistance mutations among 184 HIV-1-infected, therapy-naive subjects using the 454 sequencing platform to sequence two amplicons spanning HIV-1 reverse transcriptase codons 34-245. Samples from 19 subjects were also analyzed using the MiSeq sequencing platform for comparison. Errors and PCR resampling were addressed by tagging each HIV-1 RNA template copy (i.e., cDNA) with a unique sequence tag (Primer ID), allowing a consensus sequence to be constructed for each original template from resampled sequences. In control reactions, Primer ID reduced 454 and MiSeq errors from 71 to 2.6 and from 24 to 1.2 errors/10,000 nucleotides, respectively. MiSeq also allowed accurate sequencing of codon 65, an important drug resistance position embedded in a homopolymeric run that is poorly resolved by the 454 platform. Excluding homopolymeric positions, 14% of subjects had evidence of ≥1 resistance mutation among Primer ID consensus sequences, compared to 2.7% by bulk population sequencing. When calls were restricted to mutations that appeared twice among consensus sequence populations, 6% of subjects had detectable resistance mutations. The use of Primer ID revealed 5-15% template utilization on average, limiting the depth of deep sequencing sampling and revealing sampling variation due to low template utilization. Primer ID addresses important limitations of deep sequencing and produces less biased estimates of low-level resistance mutations in the viral population.

Abstract
INTRODUCTION The incident user design is the preferred study design in comparative effectiveness (CER) research. Usually, 180-365 days of exposure free time is adequate to remove biases associated with inclusion of prevalent users. In HIV research, the use of antiretrovirals (ARVs) at any time in the past may influence future treatment choices and CER results; thus, identifying naive as opposed to incident users is of importance. We examined misclassification of antiretroviral naive status based on Medicaid administrative data through linkage to the UNC CFAR HIV Clinical Cohort (UCHCC). METHODS We identified Medicaid patients with incident exposure to common first-line ARV regimens between 2002 and 2008 that were also patients enrolled in the UCHCC. We calculated the proportion of antiretroviral naive patients based on the UCHCC, among patients identified as having incident exposure in Medicaid and examined factors associated with being antiretroviral naive in both data sources using logistic regression to generate prevalence odds ratios and associated 95% confidence intervals. RESULTS Of the 3500 Medicaid patients with incident antiretroviral (ARV) exposure, 1344 were also enrolled in the UCHCC. In this sample, 34% were antiretroviral naive at the time of first exposure in the Medicaid data based on the UCHCC. In multivariable models, higher CD4 cell counts and log HIV RNA values were associated with being antiretroviral naive in both data sources. CONCLUSIONS Administrative data are an important source of information related to HIV treatment. As the construction of a durable and long-lasting HIV treatment plan involves knowledge of current and past antiretroviral therapy, augmentation of this data with comprehensive clinical cohort information is necessary.

Abstract
The aim of this study was to describe the retention in care and examine the factors affecting it among people living with HIV and AIDS (PLWHA) in Changsha City, China. Data on treatment, care, and their retention of all registered 822 PLWHA in Changsha Center for Disease Control and Prevention were analyzed. The retention rate had shown 58.1% among this sample. With logistic regression analysis, retention in care was significantly related to education level (senior high school vs university: odds ratio [OR] = 0.471, 95% confidence interval [CI] = 0.237-0.937), CD4 count (<50cells/mm(3) vs >500cells/mm(3): OR = 2.659, 95% CI = 1.816-28.760), and initiation of antiretroviral therapy (No vs Yes: OR = 0.362, 95% CI = 0.180-0.550). In conclusion, the intervention to improve retention in care for PLWHA in Changsha is warranted, especially for those who have lower education level, for those who have higher baseline CD4 count, and for those who have not initiated antiretroviral therapy.

Abstract
The need for antiretroviral therapy coupled with treatment of chronic co-morbidities places HIV-infected patients at risk for polypharmacy. However, few studies have described overall pill burden among HIV-infected patients. HIV-infected outpatients of the UNC Infectious Diseases Clinic were enrolled in this cross-sectional study. Subjects were contacted prior to a scheduled appointment and asked to bring all their medications to the visit. Daily total pill burden and medication type were recorded. 151 subjects were recruited: 76% male, 58% African American, 97% receiving antiretrovirals (ARVs). Median age was 48 (IRQ: 42-54) years. The median number of medications per subject was 8 (IQR: 6-11), and the median individual daily pill burden was 8 pills (IQR: 5-15): 3 pills (range: 2-5) for ARVs and 6 (range: 3-12.5) pills for non-ARVs. Duration of ART (per 2 years increase) and more than 3 co-morbidities was significantly associated with high pill burden (over 10 pills per day) with adjusted OR of 2.09 (95% CI, 1.14-3.84) and 8.04 (95% CI, 2.30-28.15), respectively. As patients with HIV age, strategies to reduce pill burden and number of medications will become increasingly critical to maintaining adherence, preventing medication errors, and serious drug-drug interactions.

Abstract
Summary Human papillomavirus (HPV) is the cause of cervical and anal cancer. Human immunodeficiency virus (HIV) infection and cocaine use are associated with increased risk for HPV infection and associated diseases, but little is known about HIV-infected drug users' awareness of HPV. We investigate HPV awareness among HIV-infected, sexually-active crack cocaine users from two inner-city hospitals in Florida and Georgia during their inpatient stays. Multivariate logistic regression analysis was used to examine potential correlates of HPV awareness. We interviewed 215 participants (110 women; 105 men) about their awareness of HPV infection. Overall, only 25% of respondents reported having heard of HPV. The odds of having heard of HPV were greater for respondents having a high-school degree or higher, having ever gone to an HIV provider for HIV care, and having two or more sexual partners. Despite increased susceptibility to HPV infection and HPV-related cancers, our study findings suggest that sexually-active HIV-infected crack cocaine users have little awareness of HPV and highlight the need for programmes targeting HPV education for HIV-infected crack cocaine drug users.

Abstract
BACKGROUND Potential liver toxicity is an important consideration for antiretroviral selection among patients coinfected with HIV and viral hepatitis (B and/or C). We sought to describe the hepatic safety profile of raltegravir in this population. METHODS Using data from HIV clinical cohorts at Johns Hopkins University and the University of North Carolina at Chapel Hill, we evaluated factors associated with liver enzyme elevations (LEEs) and calculated adverse event incidence rates for patients initiated on raltegravir-containing regimens prior to 1 January 2010. LEEs were graded according to Division of AIDS definitions. RESULTS During the study period, 456 patients received raltegravir - of whom 36% were hepatitis-coinfected (138 HCV, 17 HBV, 11 HBV+HCV). Coinfected patients were more likely to have baseline abnormal LEEs and developed severe (grade 3-4) LEEs at a rate 3.4× that of HIV-monoinfected patients (95% CI 1.28, 9.61). Among all participants, the incidence rate for first occurrence of severe LEEs was 5 per 100 person-years (95% CI 3, 7). In adjusted analyses, coinfected patients had a 2.7-fold increased hazard of severe LEEs (95% CI 1.03, 7.04). 60% of severe abnormalities occurred within 6 months after starting raltegravir; the drug was discontinued in 3 (1.3%) coinfected patients and 18 (6.2%) monoinfected patients. CONCLUSIONS Compared with HIV-monoinfected patients, those with HIV-hepatitis coinfection are at increased hazard of developing LEEs on raltegravir, at a level similar to other antiretrovirals. Severe events were uncommon, rarely leading to raltegravir discontinuation. With appropriate monitoring, raltegravir-based therapy is safe in hepatitis-coinfected patients.

Abstract
Multiple studies have shown that subtherapeutic appointment adherence and medication adherence are associated with worse clinical outcomes for people living with HIV disease. Thus, poor appointment and medication adherence diminish individual and community HIV control and transmission. Yet not enough is known about interventions that can improve retention in HIV care. The purpose of this study was to test an intervention to improve retention and/or medication adherence in a public clinic in the Deep South. One hundred participants with retention or medication adherence difficulties were randomized to either a six-month intervention or usual care, and followed longitudinally for one year. The intervention was multidimensional, based on the Information-Motivation-Behavioral Skills (IMB) model. The intervention addressed information about HIV and the importance of retention/adherence, motivation to be retained and/or adhere to medications, and the behavioral skills needed to manage and maintain these healthy behaviors in a combination of face-to-face and telephone sessions. The proportion of those with at least one visit in each four-month block (third) of the year increased in those with minimal exposure to the intervention (three out of eight intervention contacts) as compared to those with less intervention exposure (p = 0.098). Those with at least this minimal exposure averaged a significantly higher number of thirds that included a clinic visit as compared to those with less intervention exposure (p = 0.013). The intervention did not demonstrate a significant effect on medication adherence, though this is contradictory to a previous study testing a version of this intervention designed to address only medication adherence. Further study to increase uptake of the intervention is needed to increase its efficacy.

Abstract
With aging of the HIV-infected population, non-AIDS conditions such as cardiovascular disease (CVD) now account for substantial mortality and morbidity. While myocardial infarction is the major outcome of interest in the field of HIV and CVD, cerebrovascular disease remains understudied, especially in the Southeastern United States. We determined the incidence and clinical features of cerebrovascular events (CVE) in a large HIV clinical cohort in North Carolina (NC). A total of 2,515 HIV-infected adults contributed a median of 4.5 years (IQR: 2.0, 7.8) of follow-up. Fifty-three CVEs were adjudicated for an incidence rate of 3.87 per 1,000 person-years (95% CI: 2.90, 5.06). The ischemic stroke incidence was 2.26 per 1,000 person-years (95% CI: 1.53, 3.21), approximately 1.5 times the rate of a population-based cohort in NC. At the time of CVE, the median age was 48 years (IQR: 42, 55). Of ischemic strokes 76% resulted from large artery atherosclerosis or small vessel (lacunar) disease. In multivariable analyses, age, hypertension, dyslipidemia, recent CD4(+) cell count ≤200 cells/mm(3), and recent HIV RNA >400 copies/ml were associated with an increased risk of CVE. Antiretroviral therapy (ART) was not associated with the risk of CVE. We concluded that in the post-ART era, HIV-infected individuals appear to be at moderately increased risk of stroke. Prevention of CVEs in this population will require modification of traditional CVD risk factors and early, effective treatment of HIV infection.

Abstract
Background In HIV-infected populations in developed countries, the most recent published cancer incidence trend analyses are only updated through 2008. We assessed changes in the distribution of cancer types and incidence trends among HIV-infected patients in North Carolina up until 2011. Methods We linked the University of North Carolina Center for AIDS Research HIV Clinical Cohort, an observational clinical cohort of 3141 HIV-infected patients, with the North Carolina Cancer registry. Cancer incidence rates were estimated across calendar years from 2000 to 2011. The distribution of cancer types was described. Incidence trends were assessed with linear regression. Results Across 15,022 person-years of follow-up, 202 cancers were identified (incidence rate per 100,000 person-years [IR]: 1345; 95% confidence interval [CI]: 1166, 1544). The majority of cancers were virus-related (61%), including Kaposi sarcoma (N = 32) (IR: 213; 95%CI: 146, 301), non-Hodgkin lymphoma (N = 34) (IR: 226; 95%CI: 157, 316), and anal cancer (N = 16) (IR: 107; 95%CI: 61, 173). Non-Hodgkin lymphoma was observed to decrease from 2000 to 2011 (decline of 15 cases per 100,000 person-years per calendar year, 95%CI: -27, -3). No other changes in incidence or changes in incidence trends were observed for other cancers (all P > 0.20). Conclusions We observed a substantial burden of a variety of cancers in this population in the last decade. Kaposi sarcoma and non-Hodgkin lymphoma were consistently two of the greatest contributors to cancer burden across calendar time. Cancer rates appeared stable across calendar years, except for non-Hodgkin lymphoma, which appeared to decrease throughout the study period.

Abstract
Data on the effectiveness of second-line combination antiretroviral therapy (cART) are limited. We evaluated virologic outcomes of second cART in a multicenter cohort collaboration. The study population initiated first and second modern cART between 1996 and 2010. The second cART required a switch in at least the anchor agent of first cART. We evaluated time to virologic failure of second cART and factors associated with greater risk of failure using multivariable Cox proportional hazards models. Of 488 patients who switched to second-line cART, 67% were black and 32% were women. The median HIV-1 RNA at second cART initiation was 9,565 copies/ml [interquartile range (IQR); 123, 94,108]. The time to virologic failure of second cART was longer if HIV-1 RNA was undetectable at switch (p=0.001), although 12% and 17% of patients with undetectable and detectable HIV-1 RNA experienced virologic failure within 6 months of second cART initiation, respectively. A lower CD4 cell count at second cART initiation was associated with a greater risk of virologic failure. Failure rates decreased in more recent calendar years [adjusted relative hazard of 0.40 comparing 2008 to 2010 with 1996 to 1998 (95% confidence interval; 0.15, 1.00)]; however, type of anchor agent was not associated with failure. In conclusion, virologic failure of second cART was less likely if patients switched with undetectable HIV-1 RNA, although risk of early failure was similar. The effectiveness of second cART regimens improved over calendar time and was independent of the anchor agent in the regimen.

Abstract
The associations of acute HIV infection (AHI) and other predictors with transmitted drug resistance (TDR) prevalence were assessed in a cohort of HIV-infected, antiretroviral-naïve patients. AHI was defined as being seronegative with detectable HIV RNA. Binomial regression was used to estimate prevalence ratios and 95% confidence intervals for associations with TDR. Among 43 AHI patients, TDR prevalence was 20.9%, whereas prevalence was 8.6% among 677 chronically infected patients. AHI was associated with 1.9 times the prevalence of TDR (95% confidence intervals: 1.0 to 3.6) in multivariable analysis. AHI patients may represent a vanguard group that portends increasing TDR in the future.

Abstract
OBJECTIVES Despite prevention efforts, new HIV diagnoses continue in the southern United States, where the epidemic is characterized by significant racial/ethnic disparities. We integrated phylogenetic analyses with clinical data to reveal trends in local HIV transmission. DESIGN Cross-sectional analysis of 1671 HIV-infected individuals each with one B-subtype pol sequence obtained during chronic (82%; UNC Center for AIDS Research Clinical Cohort) or acute/recent (18%; Duke/UNC Acute HIV Consortium) infection. METHODS Phylogenies were inferred using neighbor joining to select related sequences then confirmed with Bayesian methods. We characterized transmission clusters (clades n ≥ 3 sequences supported by posterior probabilities = 1) by factors including race/ethnicity and transmission risk. Factors associated with cluster membership were evaluated for newly diagnosed patients. RESULTS Overall, 72% were men, 59% black and 39% men who have sex with men (MSM). A total of 557 (33%) sequences grouped in either 108 pairs (n = 216) or 67 clusters (n = 341). Clusters ranged from three to 36 (median 4) members. Composition was delineated primarily by race, with 28% exclusively black, and to a lesser extent by risk group. Both MSM and heterosexuals formed discrete clusters, although substantial mixing was observed. In multivariable analysis, patients with age 30 years or less (P = 0.009), acute infection (P = 0.02), local residence (P = 0.002) and transmitted drug resistance (P = 0.02) were more likely to be cluster members, whereas Latinos were less likely (P < 0.001). CONCLUSION Integration of molecular, clinical and demographic data offers a unique view into the structure of local transmission networks. Clustering by black race, youth and transmitted drug resistance and inability to identify Latino clusters will inform prevention, testing and linkage to care strategies.

Abstract
BACKGROUND Late diagnosis of human immunodeficiency virus (HIV) infection remains common despite advances in therapy and prognosis. The southeastern United States is a rapidly growing Latino settlement area where ethnic disparities may contribute to late presentation to care. METHODS We assessed demographic and clinical factors between racial/ethnic groups at the time of HIV care initiation in the University of North Carolina Center for AIDS Research Clinical Cohort. We identified independent predictors of late presentation, defined as a CD4(+) T lymphocyte (CD4) count <350 cells/mm(3) or an AIDS-defining event (ADE), using log-linear binomial regression. RESULTS During the period 1999-2009, 853 patients initiated HIV care, of whom 11% were Latino, 28% were white, and 61% were black. Median initial CD4 counts were lower for Latino patients (186 cells/mm(3)) than white patients (292 cells/mm(3); P = .006) and black patients (302 cells/mm(3); P = .02). Latino persons were more likely to be late presenters than white or black persons (76% vs 58%; P < .001) and accounted for 86%, 75%, and 50% of all presenting cases of active tuberculosis, histoplasmosis, and toxoplasmosis, respectively. Latino ethnicity, older age, male sex, and earlier entry year were independently associated with late presentation (P < .05 for all). In multivariable analyses, Latino persons were 1.29 times more likely to present to care late than white or black persons (95% confidence interval, 1.15-1.45). CONCLUSIONS Latinos are more likely to initiate HIV care later in the course of illness than are black and white persons and account for a majority of several ADEs. Strategies to improve earlier HIV testing among Latinos in new settlement areas are needed.

Abstract
Early linkage and retention in HIV clinical care is essential for optimal disease management, promotion of health, and receipt of secondary prevention messages to decrease onward transmission of HIV. Youth, specifically racial/ethnic minority young men who have sex with men (YMSM), continue to acquire new HIV infections and have been shown to be less likely to engage in regular HIV care and adhere to scheduled medical visits. The goal of the current study was to evaluate the characteristics of participants and program delivery that were associated with early linkage and retention in HIV care among HIV-infected YMSM of color enrolled in an outreach, linkage, and retention study. Of the 334 patients included in the linkage analysis, 72% were linked to care within 30 days of diagnosis, 81% within 60 days, and 87% within 90 days. While no patient-level characteristics were associated with early linkage, having the person who provided the positive HIV test result refer the patient to HIV care (p=0.048), specifically calling to make the appointment (p=0.009), was associated with earlier linkage. Retention of Latino participants (96.2%) was significantly higher than for the African-American (79.9%) youth (p=0.006). Overall, 221 participants had at least 1 year of possible follow-up and 82.8% of these participants were retained at 1 year. While unique challenges exist in the care of adolescents infected with HIV from identification to engagement and retention in clinical care, programs that are responsive and dedicated to the needs of these youth can be successful in retaining them in care.

Abstract
The federal government has established rapid identification, linkage, and engagement in medical care of HIV-positive individuals as a high priority. Outreach workers and other linkage coordinators are identified as key personnel in implementing this policy. Young racial/ethnic minority men who have sex with men (MSM) have relatively high and growing rates of HIV infection and would benefit from the services of outreach workers. In this article, we describe the characteristics of outreach workers employed by eight demonstration sites participating in the federal Special Projects of National Significance (SPNS) Young MSM of Color Initiative, the linkage and retention models used by the sites, and the number of outreach/ linkage contacts and individuals referred to HIV care. We summarize rates of retention of outreach workers in employment, factors associated with worker turnover, and costs associated with their replacement. We also summarize the experiences of demonstration sites in employing and retaining outreach workers and improving their performance. The insights of outreach workers are reported regarding the challenges they experienced while conducting outreach. Recommendations from demonstration site project managers and outreach workers are offered to improve workplace performance and job retention. Outreach and retention strategies, as well as lessons learned in employing outreach workers, are useful to programs serving young racial/ethnic minority MSM and other HIV-positive groups.

Abstract
BACKGROUND Patients who participate in clinical trials may experience better clinical outcomes than patients who initiate similar therapy within clinical care (trial effect), but no published studies have evaluated a trial effect in HIV clinical trials. METHODS To examine a trial effect we compared virologic suppression (VS) among patients who initiated HAART in a clinical trial versus in routine clinical care. VS was defined as a plasma HIV RNA ≤ 400 copies/ml at six months after HAART initiation and was assessed within strata of early (1996-99) or current (2000-06) HAART periods. Risk ratios (RR) were estimated using binomial models. RESULTS Of 738 persons initiating HAART, 30.6% were women, 61.7% were black, 30% initiated therapy in a clinical trial and 67% (n = 496) had an evaluable six month HIV RNA result. HAART regimens differed between the early and current periods (p < 0.001); unboosted PI regimens (55.6%) were more common in the early and NNRTI regimens (46.4%) were more common in the current period. Overall, 78% (95%CI 74, 82%) of patients achieved VS and trial participants were 16% more likely to achieve VS (unadjusted RR 1.16, 95%CI 1.06, 1.27). Comparing trial to non-trial participants, VS differed by study period. In the early period, trial participants initiating HAART were significantly more likely to achieve VS than non-trial participants (adjusted RR 1.33; 95%CI 1.15, 1.54), but not in the current period (adjusted RR 0.98; 95%CI 0.87, 1.11). CONCLUSIONS A clear clinical trial effect on suppression of HIV replication was observed in the early HAART period but not in the current period.

Abstract
The HIV-infected population in the USA is expanding as patients survive longer and new infections are identified. In many areas, particularly rural/medically underserved regions, there is a growing shortage of providers with sufficient HIV expertise. HIV services incorporated into community-based (CB), primary care settings may therefore improve the distribution and delivery of HIV treatment. Our objective was to describe/compare patients and treatment outcomes in two settings: a community-located, primary care-based HIV program, and a hospital-based (HB) specialty center. CB providers had on-site access to generalist HIV experts. The hospital center was staffed primarily by infectious disease physicians. This was a retrospective cohort study of 854 HIV-positive adults initiating care between 1/2005 and 12/2007 within an academic medical center network in the Bronx, NY. Treatment outcomes were virologic and immunologic response at 16-32 and 48 weeks, respectively, after combination antiretroviral therapy (cART) initiation. We found that HB subjects presented with a higher prevalence of AIDS (59% vs. 46%, p<0.01) and lower initial CD4 (385 vs. 437, p<0.05) than CB subjects. Among 178 community vs. 237 hospital subjects starting cART, 66% vs. 62% achieved virologic suppression (95% confidence interval (CI) difference -0.14-0.06) and 49% vs. 59% achieved immunologic success, defined as a 100 cell/mm³ increase in CD4 (95% CI difference 0.00-0.19). The multivariate-adjusted likelihoods of achieving viral suppression [OR=1.24 (95% CI 0.69-2.33)] and immunologic success [OR=0.76 (95% CI 0.47-1.21)] were not statistically significant for community vs. hospital subjects. Because this was an observational study, propensity scores were used to address potential selection bias when subjects presented to a particular setting. In conclusion, HIV-infected patients initiate care at CB clinics earlier and with less advanced HIV disease. Treatment outcomes are comparable to those at a HB specialty center, suggesting that HIV care can be delivered effectively in community settings.

Abstract
BACKGROUND In the USA, women, racial/ethnic minorities and persons who acquire HIV infection through heterosexual intercourse represent an increasing proportion of HIV-infected persons, and yet are frequently underrepresented in clinical trials. We assessed the demographic predictors of trial participation in antiretroviral-naïve patients. METHODS Patients were characterized as trial participants if highly active antiretroviral therapy (HAART) was initiated within a clinical trial. Prevalence ratios (PRs) were obtained using binomial regression. RESULTS Between 1996 and 2006, 30% of 738 treatment-naïve patients initiated HAART in a clinical trial. Trial participation rates for men who have sex with men (MSM), heterosexual men, and women were respectively 36.5, 29.6 and 24.3%. After adjustment for other factors, heterosexual men appeared less likely to participate in trials compared with MSM [PR 0.79, 95% confidence interval (CI) 0.57, 1.11], while women were as likely to participate as MSM (PR 0.97, 95% CI 0.68, 1.39). The participation rate in Black patients (25.9%) was lower compared with non-Black patients (37.5%) (adjusted PR 0.80, 95% CI 0.60, 1.06). CONCLUSIONS In our clinical setting, gender did not appear to impact participation in HIV treatment trials, but Black patients were slightly less likely to participate in these trials. Considering the substantial proportion of HIV-infected patients who are Black, future trials need to consider strategies to incorporate such underrepresented populations.

OBJECTIVE Patient antiretroviral (ARV) therapy knowledge is essential for regimen adherence, successful therapeutic response, and minimization of resistance evolution. Moreover, a complete and accurate patient ARV history is needed to construct efficacious and tolerable future regimens. In this study we assessed the ability of HIV-infected patients receiving care in a university infectious diseases clinic to accurately recall current and past ARVs. METHODS A convenience sample (n = 205) of UNC HIV Clinical Cohort participants (n = 1840) completed a comprehensive in-person interview. Patients were asked about current and ever ARV use and were provided proprietary and generic ARV names and photographs. Self-reported sensitivity for current and ever ARV use (proportion that correctly identified all recorded ARVs), was calculated using the medical record as the gold standard. RESULTS One hundred and eighty-five patients had received ARVs at some point after enrollment in the cohort study (ever users). For current ARV use (n = 138), self-reported sensitivity was 63% (95% CI: 54-71). For ever use (n = 185), sensitivity was 18% (95% CI: 13-24). CONCLUSION Self-reported cumulative ARV use is not accurate. Since HIV-infected patients are prescribed a number of medications over their treatment course, it is necessary to develop new medication reconciliation techniques that are not dependent on patient memory or knowledge in order to improve patient outcomes.

Abstract
Young men who have sex with men (YMSM) of color are at particularly increased risk for HIV infection compared to white MSM. National data highlight the need to link YMSM of color to care to improve their overall health and stem further infections, yet, there is limited data on interventions and clinical outcomes focused on engaging and retaining youth, specifically HIV-infected YMSM of color in care. To address the medical care needs of this underserved population, in 2005, the Health Research and Services Administration (HRSA) created the YMSM of Color Initiative. Utilizing a social marketing campaign targeting youth and members of their sexual and social networks, testing and outreach on college campuses and within the broader community, and a tightly linked medical-social support network, we created STYLE (Strength Through Youth Livin' Empowered), a novel intervention that sought to diagnose, engage, and retain HIV-positive black and Latino YMSM in HIV primary care services. Over a 3-year period, 81 men were either newly diagnosed or reengaged in care. Overall, 63% of the cohort was retained in clinical care; defined as attending at least one medical visit every 4 months. Compared to the 3 years prior to STYLE, the odds ratio for whether or not someone attended a clinic visit was 2.58 (95% confidence interval [CI] 1.34-4.98) if enrolled in STYLE. We conclude that compared to a pre-STYLE cohort, STYLE was an effective intervention that increased HIV diagnoses, provided efficient and timely engagement in care for both those newly diagnosed and those who had fallen out of care and improved overall retention.

Abstract
OBJECTIVE A 'test and treat' strategy to reduce HIV transmission hinges on linking and retaining HIV patients in care to achieve the full benefit of antiretroviral therapy. We integrated empirical findings and estimated the percentage of HIV-positive persons in the United States who entered HIV medical care soon after their diagnosis; and were retained in care during specified assessment intervals. METHODS We comprehensively searched databases and bibliographic lists to identify studies that collected data from May 1995 through 2009. Separate meta-analyses were conducted for entry into care and retention in care (having multiple HIV medical visits during specified assessment intervals) stratified by methodological variables. All analyses used random-effects models. RESULTS Overall, 69% [95% confidence interval (CI) 66-71%, N = 53 323, 28 findings] of HIV-diagnosed persons in the United States entered HIV medical care averaged across time intervals in the studies. Seventy-two percent (95% CI 67-77%, N = 6586, 12 findings) entered care within 4 months of diagnosis. Seventy-six percent (95% CI 66-84%, N = 561, 15 findings) entered care after testing HIV-positive in emergency/urgent care departments and 67% (95% CI 64-70%, N = 52 762, 13 findings) entered care when testing was done in community locations. With respect to retention in care, 59% (95% CI 53-65%, N = 75 655, 28 findings) had multiple HIV medical care visits averaged across assessment intervals of 6 months to 3-5 years. Retention was lower during longer assessment intervals. CONCLUSION Entry and retention in HIV medical care in the United States are moderately high. Improvement in both outcomes will increase the success of a test and treat strategy.

Abstract
Delayed entry into HIV clinical care and poor retention during care has been associated with increased morbidity and mortality. To characterize the reasons for patients who eventually did enter HIV care after a delay and/or returned to care after a gap of 6 months or more, 130 semi-structured interviews about barriers to and facilitators for prompt entry into and sustained HIV clinical care were conducted in a clinic setting in the Deep South; responses were coded and analyzed quantitatively. Barriers or facilitators were positioned within superordinate categories of personal and structural barriers or facilitators and denial. Personal barriers for entry into care outweighed structural barriers, with denial being reported by 74% of the sample. Barriers to retention in care were more evenly distributed between personal and structural barriers, with denial being a barrier for 24%. Because of the high incidence of denial-based barriers, the role of this barrier and its resolution should be explored further.

Abstract
BACKGROUND There are very limited data available of the correlates of HIV-infected crack users who have never been to HIV care. METHODS Interviews were conducted at bedside with HIV-infected crack cocaine users who were recruited from the inpatient wards at Jackson Memorial Hospital in Miami, FL, and Grady Memorial Hospital in Atlanta, GA, between August 2006 and July 2009. Participants were asked about their sociodemographic characteristics, drug use, drug/alcohol treatment history, use of HIV care, perceived social support, and mental health status. Multiple logistic regression was performed to identify factors associated with never having been to HIV care. RESULTS Among 355 study participants, 21% reported never having been to a doctor or clinic for HIV care. Higher adjusted odds of never having been in care were associated with an annual income of less than $5000 [adjusted odds ratio (AOR) = 8.17, 95% confidence interval (CI) = 3.35 to 19.94], residence in Atlanta compared with Miami (AOR = 2.57, 95% CI = 1.36 to 4.83), no history of drug treatment (AOR = 4.13, 95% CI = 2.24 to 7.62), and not being helped into care at the time of HIV diagnosis (AOR = 2.83, 95% CI = 1.56 to 5.15). CONCLUSIONS Our data show that a significant proportion of HIV-infected crack cocaine users in 2 city hospitals have never been to HIV care. Interventions at the time of HIV diagnosis and drug treatment participation may facilitate linkage to care.

Abstract
BACKGROUND Amplification based HIV-1 viral load and genotypic resistance assays are expensive, technologically complex and may be difficult to implement in resource limited settings. Inexpensive, simpler assays are urgently needed. OBJECTIVES To determine the suitability of the ExaVir Load and ExaVir Drug assays for use in patient monitoring. STUDY DESIGN Specimens from 108 adults were used to compare ExaVir Load HIV-1 RT to Amplicor HIV-1 Monitor HIV-1 RNA, and ExaVir Drug phenotype to HIV GenoSure genotype. RESULTS HIV-1 RT and HIV-1 RNA levels were comparable (Pearson correlation coefficient 0.83). Most (94%) had detectable results in both assays. The mean difference (HIV-1 RT minus HIV-1 RNA) was -0.21 log(10)cps/mLequiv. Relationship between HIV-1 RT and HIV-1 RNA was not affected by RT mutations, CD4 cell count, or efavirenz (EFV) or nevirapine (NVP) use. Phenotypes were generally consistent with genotype findings for EFV, but not for NVP. Most patients (93.9%) with phenotypic EFV resistance had at least one EFV mutation, while 78.0% of patients with phenotypic NVP resistance had at least one NVP mutation. Eleven of 49 samples tested for EFV susceptibility were found resistant (n=2) or with reduced susceptibility (n=9) despite the absence of genotypic resistance. Eleven of 45 samples tested for NVP susceptibility were found resistant (n=9) or with reduced susceptibility (n=2) with no evidence of genotypic mutations. CONCLUSIONS The ExaVir Load assay performed well and may be an alternative to amplification based techniques for HIV-1 RNA quantification. The ExaVir Drug assay for phenotypic resistance testing requires further evaluation, especially for NVP.

Abstract
Current national guidelines recommend that all HIV care providers routinely counsel their HIV-infected patients about reducing HIV transmission behaviors. In this article we identify the challenges and lessons learned from implementing a provider-delivered HIV transmission risk-reduction intervention for HIV-infected patients (Positive Steps). Based on a multi-site Centers for Disease Control and Prevention (CDC) initiative, we integrated the Positive Steps program into an infectious diseases clinic in North Carolina. Of the nearly 1200 HIV-infected patients, 59% were African American, 44% were white, 33% were women, and over 50% were between 25 and 44 years of age. We obtained feedback from a community advisory board, input from clinic staff, and conducted formative interviews with clinic patients and providers to achieve overall acceptance of the program within the clinic. Clinic providers underwent training to deliver standardized prevention counseling. During program implementation we conducted a quality assessment of program components, including reviewing whether patients were screened for HIV transmission risk behaviors and whether providers counseled their patients. Once Positive Steps was implemented, on average, 69% of patients were screened and 77% of screened patients were counseled during the first 12 months. In analyses of quarterly exit surveys of patients after their medical exams, on average, 73% of respondents reported being asked about safer sex and 51% reported having safer-sex discussions with their providers across six quarterly periods. Of those who had discussions, 91% reported that those discussions were "very" or "moderately helpful." Providers reported time and competing medical priorities as barriers for discussing prevention with patients, however, provider-delivered counseling was routinely performed for 12 months. Overall, the findings indicate that the Positive Steps program was successfully integrated in an infectious diseases clinic and received well by patients.

Abstract
Early HIV diagnosis and treatment are important for decreasing HIV transmission and morbidity. By using initial CD4 counts and time to first viral load test, we examined the stage of disease at the time of diagnosis and the time to accessing medical care after diagnosis, respectively. Initial CD4 count, first HIV viral load test, demographics and exposure risks were obtained for all newly diagnosed HIV cases in Northern Alberta from 1998-2003. Time to accessing care was determined as the time between diagnosis and the first viral load test. Correlates were determined using simple descriptive statistics and survival analysis methods. Of 526 HIV cases, median age was 36 years (interquartile range [IQR]: 31-43), 69% were males and 41% were Aboriginal. At diagnosis, 28% of the population had CD4 counts less than 200 cells=mm3. After diagnosis, 92.2% accessed care and median time to care for the entire population was 29 days. In multivariate analysis, age at diagnosis less than 45 years was independently associated with longer median time to care (versus age 45 years or more; adjusted hazard ratio [AHR]: 0.69; 95% confidence interval [CI] 0.55-0.88), while Aboriginal ethnicity (versus Caucasian; AHR: 0.82; 95% CI 0.68-1.01), and nonmetropolitan residence (versus metropolitan; AHR: 0.81; 95% CI 0.65-1.00) were marginally significant correlates for longer times to care. Although more than one quarter of cases were diagnosed at relatively advanced stages of infection, the majority of new HIV cases in Northern Alberta accessed care within 2 months of diagnosis. We need to explore new strategies to facilitate and promote earlier access to testing among individuals at risk.
