A systematic review of HIV/AIDS survival and delayed diagnosis among Hispanics in the United States

Significant association between perceived HIV related stigma and late presentation for HIV/AIDS care in low and middle-income countries: A systematic review and meta-analysis

BACKGROUND

Late presentation for human immunodeficiency virus (HIV) care is a major impediment for the success of antiretroviral therapy (ART) outcomes. The role that stigma plays as a potential barrier to timely diagnosis and treatment of HIV among people living with HIV/AIDS (acquired immunodeficiency syndrome) is ambivalent. This review aimed to assess the best available evidence regarding the association between perceived HIV related stigma and time to present for HIV/AIDS care.

METHODS

Quantitative studies conducted in English language between 2002 and 2016 that evaluated the association between HIV related stigma and late presentation for HIV care were sought across four major databases. This review considered studies that included the following outcome: 'late HIV testing', 'late HIV diagnosis' and 'late presentation for HIV care after testing'. Data were extracted using a standardized Joanna Briggs Institute (JBI) data extraction tool. Meta- analysis was undertaken using Revman-5 software. I2 and chi-square test were used to assess heterogeneity. Summary statistics were expressed as pooled odds ratio with 95% confidence intervals and corresponding p-value.

RESULTS

Ten studies from low- and middle- income countries met the search criteria, including six (6) and four (4) case control studies and cross-sectional studies respectively. The total sample size in the included studies was 3,788 participants. Half (5) of the studies reported a significant association between stigma and late presentation for HIV care. The meta-analytical association showed that people who perceived high HIV related stigma had two times more probability of late presentation for HIV care than who perceived low stigma (pooled odds ratio = 2.4; 95%CI: 1.6-3.6, I2 = 79%).

CONCLUSIONS

High perceptions of HIV related stigma influenced timely presentation for HIV care. In order to avoid late HIV care presentation due the fear of stigma among patients, health professionals should play a key role in informing and counselling patients on the benefits of early HIV testing or early entry to HIV care. Additionally, linking the systems and positive case tracing after HIV testing should be strengthened.

HIV Testing Behaviors Among Latina Women Tested for HIV in Florida, 2012

INTRODUCTION

Latina women in the United States (US) are not only disproportionately affected by human immunodeficiency virus (HIV) infection but also underuse HIV prevention services, such as HIV testing.

METHOD

HIV testing events were examined to describe the HIV testing behaviors and test results among Latinas tested in 2012 at publicly funded sites in Florida, United States. Multivariable logistic regression was used to assess the demographic characteristics associated with reports of previous testing and positive HIV test results.

RESULTS

Of the 184,037 testing events, 87,569 (45.6%) were among non-Hispanic Blacks (NHBs), 47,926 (26.0%) non-Hispanic Whites (NHWs), 41,117 (22.3%) Latinas, 5,672 (3.1%) those with unknown race/ethnicity, and 1,753 (1.0%) other racial/ethnic groups. Compared to NHW and NHB women, Latinas testing for HIV were older (mean age = 32.1, NHW = mean age 30.3, NHB = mean age 30.0; p < .0001). Results indicated that women who reported previous HIV testing had decreased odds of being Latina (adjusted odds ratio = 0.90; 95% confidence interval [0.87, 0.94]).

CONCLUSION

These findings indicate that Latinas are underusing HIV testing, and efforts are needed to increase the proportion of Latinas, especially younger Latinas, tested for HIV in Florida.

HIV risk behaviours among immigrant and ethnic minority gay and bisexual men in North America and Europe: A systematic review

HIV surveillance systems show that gay, bisexual, and other men who have sex with men (MSM) bear a disproportionate burden of HIV in North American and European countries. Within the MSM category, HIV prevalence is often elevated among ethnic minority (i.e., Latino, Asian, and Black) MSM, many of whom are also foreign-born immigrants. Little research has focused specifically on foreign-born populations, though studies that provide data on the nativity of their samples offer an opportunity to investigate the potential role of transnational migration in informing HIV risk among ethnic minority MSM. This systematic review of ethnic minority MSM studies where the nativity of the sample is known provides a robust alternative to single studies measuring individual-level predictors of HIV risk behaviour. In this review, HIV prevalence, unprotected sex, drug use, and HIV testing are analysed in relation to the ethnicity, nativity, and location of the samples included. The results, which include high rates of HIV, unprotected sex, and stimulant use in foreign-born Latino samples and high rates of alcohol and club drug use in majority foreign-born Asian Pacific Islander (API) samples, provide baseline evidence for the theory of migration and HIV risk as syndemics within ethnic minority populations in North American and European countries. The findings also suggest that further research on the contextual factors influencing HIV risk among ethnic minority MSM groups and especially immigrants within these groups is needed. These factors include ethnic networks, individual post-migration transitions, and the gay communities and substance use cultures in specific destination cities. Further comparative work may also reveal how risk pathways differ across ethnic groups.

Shifting the HIV Training and Research Paradigm to Address Disparities in HIV Outcomes

Tailored programs to diversify the pool of HIV/AIDS investigators and provide sufficient training and support for minority investigators to compete successfully are uncommon in the US and abroad. This paper encourages a shift in the HIV/AIDS training and research paradigm to effectively train and mentor Latino researchers in the US, Latin America and the Caribbean. We suggest three strategies to accomplish this: (1) coaching senior administrative and academic staff of HIV/AIDS training programs on the needs, values, and experiences unique to Latino investigators; (2) encouraging mentors to be receptive to a different set of research questions and approaches that Latino researchers offer due to their life experiences and perspectives; and (3) creating a virtual infrastructure to share resources and tackle challenges faced by minority researchers. Shifts in the research paradigm to include, retain, and promote Latino HIV/AIDS researchers will benefit the scientific process and the patients and communities who await the promise of HIV/AIDS research.

Tu Amigo Pepe: Evaluation of a Multi-media Marketing Campaign that Targets Young Latino Immigrant MSM with HIV Testing Messages

Latino immigrant men who have sex with men (MSM) are at risk for HIV and delayed diagnosis in the United States. This paper describes the evaluation of a pilot of the Tu Amigo Pepe, a multimedia HIV testing campaign aimed at Latino MSM in Seattle, WA particularly targeting immigrants who may not identify as gay, ages 18-30 years old. The 16-week campaign included Spanish-language radio public service announcements (PSAs), a Web site, social media outreach, a reminder system using mobile technology, print materials and a toll-free hotline. In developing the PSAs, the Integrated Behavioral Model was used as a framework to reframe negative attitudes, beliefs and norms towards HIV testing with positive ones as well as to promote self-efficacy towards HIV testing. The campaign had a significant and immediate impact on attitudes, beliefs, norms and self-efficacy towards HIV testing as well as on actual behavior, with HIV testing rates increasing over time.

The impact of ethnicity/race on the association between the Veterans Aging Cohort Study (VACS) Index and neurocognitive function among HIV-infected persons

The Veterans Aging Cohort Study (VACS) Index was developed as a risk index for health outcomes in HIV, and it has been consistently associated with mortality. It shows a significant, yet relatively weak, association with neurocognitive impairment, and little is known about its utility among ethnic/racial minority groups. We examined whether the association between the VACS Index and neurocognition differed by ethnic/racial group. Participants included 674 HIV-infected individuals (369 non-Hispanic whites, 111 non-Hispanic blacks, and 194 Hispanics). Neurocognitive function was assessed via a comprehensive battery. Scaled scores for each neurocognitive test were averaged to calculate domain and global neurocognitive scores. Models adjusting for demographics and HIV disease characteristics not included in the VACS Index showed that higher VACS Index scores (indicating poorer health) were significantly associated with worse global neurocognition among non-Hispanic whites. This association was comparable in non-Hispanic blacks, but nonsignificant among Hispanics (with similar results for English and Spanish speaking). We obtained comparable findings in analyses adjusting for other covariates (psychiatric and medical comorbidities and lifestyle factors). Analyses of individual neurocognitive domains showed similar results in learning and delayed recall. For other domains, there was an effect of the VACS Index and no significant interactions with race/ethnicity. Different components of the VACS Index were associated with global neurocognition by race/ethnicity. In conclusion, the association between the VACS Index and neurocognitive function differs by ethnic/racial group. Identifying key indicators of HIV-associated neurocognitive impairment by ethnic/racial group might play an important role in furthering our understanding of the biomarkers of neuroAIDS.

HIV treatment cascade in migrants and mobile populations

PURPOSE OF REVIEW

Health policy makers aspire to achieve an HIV treatment 'cascade' in which diagnostic and treatment services are accessed early and routinely by HIV-infected individuals. However, migrants and highly mobile individuals are likely to interact with HIV treatment programs and the healthcare system in ways that reflect their movement through time and place, affecting their successful progression through the HIV treatment cascade. We review recent research that has examined the challenges in effective and sustained HIV treatment for migrants and mobile populations.

RECENT FINDINGS

Mobility is associated with increased risk of antiretroviral therapy (ART) nonadherence, lost to follow-up, deterioration in CD4 count, HIV-related death, development of drug resistance and general noncontinuity of HIV care. Migrants' slow progression through the HIV treatment cascade can be attributed to feelings of confusion, helplessness; an inability to effectively communicate in the native language; poor knowledge about administrative or logistical requirements of the healthcare system; the possibility of deportation or expulsion based on the legal status of the undocumented migrant; fear of disclosure and social isolation from the exile or compatriot group. Travel or transition to the host country commonly makes it difficult for migrants to remain enrolled in ART programs and to maintain adherence to treatment.

SUMMARY

Existing public health systems fail to properly account for migration, and actionable knowledge of the health requirements of migrants is still lacking. A large body of research has shown that migrants are more likely to enter into the healthcare system late and are less likely to be retained at successive stages of the HIV treatment cascade. HIV-infected migrants are especially vulnerable to a wide range of social, economic and political factors that include a lack of direct access to healthcare services; exposure to difficult or oppressive work environments; the separation from family, friends and a familiar sociocultural environment. Realizing the full treatment and preventive benefits of the UNAIDS 90-90-90 strategy will require reaching all marginalized subpopulations of which migrants are a particularly large and important group.

HIV Testing Among Black and Hispanic Immigrants in the United States

Late presentation is common among black and Hispanic US immigrants living with HIV. Little is known about HIV testing in this population because data are aggregated into racial and ethnic categories without regard to nativity. This study was undertaken to determine HIV testing patterns in these populations. We used data from the National Health Interview Survey (2007-2010), a nationally representative source of HIV testing data disaggregated by nativity. The sample consisted of 10,397 immigrants (83.9% Hispanic white, 13.1% non-Hispanic black, and 3.0% Hispanic black). The majority of participants were from the Caribbean, Central America, and Mexico (81.5%). Hispanic white immigrants were least likely to have undergone testing compared with non-Hispanic and Hispanic black immigrants (46.7% vs. 70.5% and 65.8%). Among immigrants with known risk factors or prior STDs, 59.2% and 74.8% reported previous HIV testing. Immigrants who had not recently talked to a healthcare provider were less likely to report testing: Hispanic white (AOR 0.65, 95% CI 0.58-0.72), non-Hispanic black (AOR 0.64, 95% CI 0.48-0.85), and Hispanic black (AOR 0.26, 95% CI 0.14-0.48). Only 17.2% of all immigrants intended to undergo HIV testing in the 12 months following participation in the survey. Among all three racial and ethnic groups, immigrants who reported a history of prior STDs were more likely to intend to test for HIV in the future. Many black and Hispanic immigrants to the United States have not undergone HIV testing. Interventions to increase access to HIV testing and awareness of transmission risk should be developed.

Cell phone utilization among foreign-born Latinos: a promising tool for dissemination of health and HIV information

Latinos in the US are disproportionately affected by HIV and are at risk for late presentation to care. Between June 2011 and January 2012, we conducted a cross-sectional survey of 209 Baltimore Latinos at community-based venues to evaluate the feasibility of using information communication technology-based interventions to improve access to HIV testing and education within the Spanish-speaking community in Baltimore. Participants had a median age of 33 years interquartile range (IQR) (IQR 28-42), 51.7 % were male, and 95.7 % were foreign-born. Approximately two-thirds (63.2 %) had been in the US less than 10 years and 70.1 % had been previously tested for HIV. Cell phone (92.3 %) and text messaging (74.2 %) was used more than Internet (52.2 %) or e-mail (42.8 %) (p < 0.01). In multivariate analysis, older age and lower education were associated with less utilization of Internet, e-mail and text messaging, but not cell phones. Interest was high for receiving health education (73.1 %), HIV education (70.2 %), and test results (68.8 %) via text messaging. Innovative cell phone-based communication interventions have the potential to link Latino migrants to HIV prevention, testing and treatment services.

Survival rate of AIDS disease and mortality in HIV-infected patients: a meta-analysis

BACKGROUND

The life expectancy of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) reported by several epidemiological studies is inconsistent. This meta-analysis was conducted to estimate the survival rate from HIV diagnosis to AIDS onset and from AIDS onset to death.

METHODS

The electronic databases PubMed, Web of Science and Scopus were searched to February 2016. In addition, the reference lists of included studies were checked to identify further references, and the database of the International AIDS Society was also searched. Cohort studies addressing the survival rate in patients diagnosed with HIV/AIDS were included in this meta-analysis. The outcomes of interest were the survival rate of patients diagnosed with HIV progressing to AIDS, and the survival rate of patients with AIDS dying from AIDS-related causes with or without highly active antiretroviral therapy (HAART). The survival rate (P) was estimated with 95% confidence intervals based on random-effects models.

RESULTS

In total, 27,862 references were identified, and 57 studies involving 294,662 participants were included in this meta-analysis. Two, 4-, 6-, 8-, 10- and 12-year survival probabilities of progression from HIV diagnosis to AIDS onset were estimated to be 82%, 72%, 64%, 57%, 26% and 19%, respectively. Two, 4-, 6-, 8- and 10-year survival probabilities of progression from AIDS onset to AIDS-related death in patients who received HAART were estimated to be 87%, 86%, 78%, 78%, and 61%, respectively, and 2-, 4- and 6-year survival probabilities of progression from AIDS onset to AIDS-related death in patients who did not receive HAART were estimated to be 48%, 26% and 18%, respectively. Evidence of considerable heterogeneity was found. The majority of the studies had a moderate to high risk of bias.

CONCLUSION

The majority of HIV-positive patients progress to AIDS within the first decade of diagnosis. Most patients who receive HAART will survive for >10 years after the onset of AIDS, whereas the majority of the patients who do not receive HAART die within 2 years of the onset of AIDS.

Health outcomes among HIV-positive Latinos initiating antiretroviral therapy in North America versus Central and South America

Introduction

Latinos living with HIV in the Americas share a common ethnic and cultural heritage. In North America, Latinos have a relatively high rate of new HIV infections but lower rates of engagement at all stages of the care continuum, whereas in Latin America antiretroviral therapy (ART) services continue to expand to meet treatment needs. In this analysis, we compare HIV treatment outcomes between Latinos receiving ART in North America versus Latin America.

Methods

HIV-positive adults initiating ART at Caribbean, Central and South America Network for HIV (CCASAnet) sites were compared to Latino patients (based on country of origin or ethnic identity) starting treatment at North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) sites in the United States and Canada between 2000 and 2011. Cox proportional hazards models compared mortality, treatment interruption, antiretroviral regimen change, virologic failure and loss to follow-up between cohorts.

Results

The study included 8400 CCASAnet and 2786 NA-ACCORD patients initiating ART. CCASAnet patients were younger (median 35 vs. 37 years), more likely to be female (27% vs. 20%) and had lower nadir CD4 count (median 148 vs. 195 cells/µL, p<0.001 for all). In multivariable analyses, CCASAnet patients had a higher risk of mortality after ART initiation (adjusted hazard ratio (AHR) 1.61; 95% confidence interval (CI): 1.32 to 1.96), particularly during the first year, but a lower hazard of treatment interruption (AHR: 0.46; 95% CI: 0.42 to 0.50), change to second-line ART (AHR: 0.56; 95% CI: 0.51 to 0.62) and virologic failure (AHR: 0.52; 95% CI: 0.48 to 0.57).

Conclusions

HIV-positive Latinos initiating ART in Latin America have greater continuity of treatment but are at higher risk of death than Latinos in North America. Factors underlying these differences, such as HIV testing, linkage and access to care, warrant further investigation.

Systematic Assessment of Linkage to Care for Persons with HIV Released from Corrections Facilities Using Existing Datasets

Populations in corrections continue to have high prevalence of HIV. Expanded testing and treatment programs allow persons to be identified and stabilized on treatment while incarcerated. However, these gains and frequently lost on reentry. Systemic frameworks are needed to monitor linkage to care to guide programs supporting linkage to care. To assess the adequacy of linkage to care on reentry, incarceration data from the National Corrections Reporting Program and data from the Ryan White Services Report from 2010 to 2012 were linked using an encrypted client identification (eUCI). Time from release to the first visit and presence of detectable HIV RNA at linkage were assessed. Multivariate survival analyses were performed to identify associations between patient characteristics and time to linkage. Among those linking, only 43% in Rhode Island and 49% in North Carolina linked within 90 days, and 33% in both states had detectable viremia at the first visit. Those not previously in care and with shorter incarceration experiences longer linkage times. Persons identified as black, had median times greater than 1 year. Using existing datasets, significant gaps in linkage to care for persons with HIV on release from corrections were demonstrated in Rhode Island and North Carolina. Systemically implementing this monitoring to evaluate changes over time would provide important information to support interventions to improve linkage in high-risk populations. Using national datasets for both corrections and clinical data, this framework equally could be used to evaluate experiences of persons with HIV linking to care on release from corrections facilities nationwide.

Homelessness, HIV, and Incomplete Viral Suppression

BACKGROUND

The importance of HIV viral suppression is widely known, however few studies have examined the effects of homelessness on HIV viral suppression.

METHODS

The study included HIV-seropositive patients in a health care for the homeless program (HCH). Electronic medical record data for 138 patients were analyzed to compare demographic characteristics, health characteristics, and utilization by housing status. For the 95 individuals with available HIV viral loads, multivariable logistic analysis was performed to examine factors associated with incomplete viral suppression.

RESULTS

The adjusted odds ratio of incomplete HIV viral load suppression was 3.84 times higher in homeless compared with housed (95% CI 1.36- 10.36) individuals. Illicit drug use and combined antiretrovirals (cART) were associated with HIV viral suppression.

CONCLUSIONS

Homelessness predicted incomplete HIV viral suppression. Stable housing may improve viral suppression and access to cART. Drug use was associated with viral suppression, likely because of patient engagement with on-site addiction services.

Cancer statistics for Hispanics/Latinos, 2015

Cancer is the leading cause of death among Hispanics/Latinos, who represent the largest racial/ethnic minority group in the United States, accounting for 17.4% (55.4 million/318 million) of the total US population in 2014. Every 3 years, the American Cancer Society reports on cancer statistics for Hispanics based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among Hispanics in 2015, there will be an estimated 125,900 new cancer cases diagnosed and 37,800 cancer deaths. For all cancers combined, Hispanics have 20% lower incidence rates and 30% lower death rates compared with non-Hispanic whites (NHWs); however, death rates are slightly higher among Hispanics during adolescence (aged 15-19 years). Hispanic cancer rates vary by country of origin and are generally lowest in Mexicans, with the exception of infection-associated cancers. Liver cancer incidence rates in Hispanic men, which are twice those in NHW men, doubled from 1992 to 2012; however, rates in men aged younger than 50 years declined by 43% since 2003, perhaps a bellwether of future trends for this highly fatal cancer. Variations in cancer risk between Hispanics and NHWs, as well as between subpopulations, are driven by differences in exposure to cancer-causing infectious agents, rates of screening, and lifestyle patterns. Strategies for reducing cancer risk in Hispanic populations include increasing the uptake of preventive services (e.g., screening and vaccination) and targeted interventions to reduce obesity, tobacco use, and alcohol consumption.

An Integrated Service Delivery Model to Identify Persons Living with HIV and to Provide Linkage to HIV Treatment and Care in Prioritized Neighborhoods: A Geotargeted, Program Outcome Study

BACKGROUND

Recent studies have demonstrated that high human immunodeficiency virus (HIV) prevalence (2.1%) rates exist in "high-risk areas" of US cities that are comparable to rates in developing nations. Community-based interventions (CBIs) have demonstrated potential for improving HIV testing in these areas, thereby facilitating early entry and engagement in the HIV continuum of care. By encouraging neighborhood-based community participation through an organized community coalition, Project LINK sought to demonstrate the potential of the CBI concept to improve widespread HIV testing and referral in an area characterized by high poverty and HIV prevalence with few existing HIV-related services.

OBJECTIVE

This study examines the influence of Project LINK to improve linkage-to-care and HIV engagement among residents of its target neighborhoods.

METHODS

Using a venue-based sampling strategy, survey participants were selected from among all adult participants aged 18 years or more at Project LINK community events (n=547). We explored multilevel factors influencing continuum-of-care outcomes (linkage to HIV testing and CBI network referral) through combined geospatial-survey analyses utilizing hierarchical linear model methodologies and random-intercept models that adjusted for baseline effect differences among zip codes. The study specifically examined participant CBI utilization and engagement in relation to individual and psychosocial factors, as well as neighborhood characteristics including the availability of HIV testing services, and the extent of local prevention, education, and clinical support services.

RESULTS

Study participants indicated strong mean intention to test for HIV using CBI agencies (mean 8.66 on 10-point scale [SD 2.51]) and to facilitate referrals to the program (mean 8.81 on 10-point scale [SD 1.86]). Individual-level effects were consistent across simple multiple regression and random-effects models, as well as multilevel models. Participants with lower income expressed greater intentions to obtain HIV tests through LINK (P<.01 across models). HIV testing and CBI referral intention were associated with neighborhood-level factors, including reduced availability of support services (testing P<.001), greater proportion of black/African Americans (testing and referral P<.001), and reduced socioeconomic capital (testing P=.017 and referral P<.001). Across models, participants expressing positive attitudes toward the CBI exhibited greater likelihood of engaging in routine HIV testing (P<.01) and referring others to HIV care (P<.01). Transgender individuals indicated greater intent to refer others to the CBI (P<.05). These outcomes were broadly influenced by distal community-level factors including availability of neighborhood HIV support organizations, population composition socioeconomic status, and high HIV prevalence.

CONCLUSIONS

Project LINK demonstrated its potential as a geotargeted CBI by evidencing greater individual intention to engage in HIV testing, care, and personal referrals to its coalition partner organizations. This study highlights important socioecological effects of US-based CBIs to improve HIV testing and initiate acceptable mechanisms for prompt referral to care among a vulnerable population.

Cultural influences on HIV testing among Latino youth

Young Latinos aged 13-24 years in the USA are disproportionately impacted upon by HIV. Despite the elevated risk, lower rates of HIV testing have been documented among Latino youth relative to other racial/ethnic groups. The objective of the current study was to examine the influence of acculturation and cultural values on HIV testing among Latino youth. The study consisted of 51 sexually experienced young Latinos aged 13-16 years from a major city in the Southeastern USA. Participants completed a survey on HIV testing history, cultural orientation and Latino cultural values. Results indicate that 21.6% of the young people had been tested for HIV. The number of times tested ranged from one to four (M = 1.9 ± 1.0). HIV testing was associated with US American cultural orientation and familism (and emphasis on strong family commitment, family support and emotional closeness). Participants with greater orientation to US American culture were more likely, whereas those who endorsed higher familism value were less likely, to have had an HIV test. For participants scoring high on familism, the desire to maintain family honour may serve as a deterrent to testing. Incorporating culturally relevant strategies, such as promoting sexual communication and conversations on HIV prevention within the family, may enhance testing and narrow the gap in HIV infection between Latino youth and other ethnic groups.

Characterization of the Hispanic or latino population in health research: a systematic review

The size and diversity of the Hispanic population in the United States has dramatically increased, with vast implications for health research. We conducted a systematic review of the characterization of the Hispanic population in health research and described its implications. Relevant studies were identified by searches of PubMed, Embase Scopus, and Science/Social Sciences Citation Index from 2000 to 2011. 131 articles met criteria. 56% of the articles reported only "Hispanic" or "Latino" as the characteristic of the Hispanic research population while no other characteristics were reported. 29% of the articles reported language, 27% detailed country of origin and 2% provided the breakdown of race. There is great inconsistency in reported characteristics of Hispanics in health research. The lack of detailed characterization of this population ultimately creates roadblocks in translating evidence into practice when providing care to the large and increasingly diverse Hispanic population in the US.

Attitudes towards couples HIV testing and counseling among Latino men who have sex with men in the Seattle area

Men who have sex with men (MSM) remain the most severely affected risk group in the US HIV/AIDS epidemic. One-third to two-thirds of HIV transmissions among MSM are estimated to come from primary sex partners. Couples HIV testing and counseling (CHTC), in which two individuals receive pre-test counseling, HIV testing and post-test prevention planning together, has been adapted for male couples in the USA, and is now available in more than 30 cities. Previous studies have demonstrated high levels of willingness to use CHTC among MSM, but to date no studies have explored this among Latino MSM (LMSM). To examine the willingness to use CHTC among and further cultural adaptation needed for LMSM, focus group discussions were held with men who self-identified as Latino, were in a relationship with another man, and resided in Seattle. Willingness to use CHTC was high. Participants reported that CHTC could strengthen and validate their relationships, help mitigate stigma, and provide a forum for support, protection, and information sharing. Barriers to CHTC use included fears of rejection, loneliness, and relationship dissolution, and concerns around deportation and financial burden. The high levels of reported willingness to use CHTC among this sample of LMSM point to the potential for CHTC to be further adapted to provide dyadic HIV testing services for LMSM.

Delayed linkage to care in one-third of HIV-positive individuals in the Netherlands

OBJECTIVES

To determine time to linkage to HIV care following diagnosis and to identify risk factors for delayed linkage.

METHODS

Patients newly diagnosed with HIV at sexually transmitted infections (STI) clinics in the Netherlands were followed until linkage to care. Data were collected at the time of diagnosis and at first consultation in care, including demographics, behavioural information, CD4+ counts and HIV viral load (VL) measurements. Delayed linkage to care was defined as >4 weeks between HIV diagnosis and first consultation.

RESULTS

310 participants were included; the majority (90%) being men who have sex with men (MSM). For 259 participants (84%), a date of first consultation in care was known; median time to linkage was 9 days (range 0-435). Overall, 95 (31%) of the participants were not linked within 4 weeks of diagnosis; among them, 44 were linked late, and 51 were not linked at all by the end of study follow-up. Being young (<25 years), having non-Western ethnicity or lacking health insurance were independently associated with delayed linkage to care as well as being referred to care indirectly. Baseline CD4+ count, VL, perceived social support and stigma at diagnosis were not associated with delayed linkage. Risk behaviour and CD4+ counts declined between diagnosis and linkage to care.

CONCLUSIONS

Although most newly diagnosed patients with HIV were linked to care within 4 weeks, delay was observed for one-third, with over half of them not yet linked at the end of follow-up. Vulnerable subpopulations (young, uninsured, ethnic minority) were at risk for delayed linkage. Testing those at risk is not sufficient, timely linkage to care needs to be better assured as well.

Explaining the appeal for immigrant men who have sex with men of a community-based rapid HIV-testing site in Montreal (Actuel sur Rue)

Immigrant men who have sex with men (MSM) are vulnerable to HIV. In the last decade, several rapid HIV-testing facilities targeting MSM have been established around the world and seem popular among immigrants. This study analyzes factors contributing to immigrant MSM's use of Actuel sur Rue (AsR), a community-based rapid HIV-testing site in Montreal's gay village, where 31% of clients are immigrants. From October 2013 to January 2014, AsR staff compiled a list of new clients born outside of Canada. With their consent, 40 immigrant MSM were reached among these new clients for a 15-minute phone survey entailing open-ended and multiple-choice questions. The survey sought immigrant MSM's reasons for visiting AsR; satisfaction with service and staff; and open comments. An inductive thematic analysis was conducted with the qualitative data, and descriptive statistics were produced with the quantitative data. The qualitative findings indicate that the main reasons for seeking an HIV test were a recent risk, routine testing, or being in a new relationship. Clients chose AsR mainly because it is easily accessible, service is fast or they heard about it from a friend. The quantitative findings indicate that rates of satisfaction were high (over 90% were satisfied about all aspects except for openings hours) and more than 80% felt comfortable while receiving services at AsR. Nevertheless, this study's findings have implications for improving services. They stress the importance of offering rapid yet comprehensive service and of taking into account immigrant MSM's concerns for confidentiality.

HIV-Related Mortality Among Adults (≥ 18 years) of Various Hispanic or Latino Subgroups--United States, 2006-2010

Hispanics or Latinos residing in the USA are disproportionately affected by HIV when compared to whites. Health outcomes for Hispanics or Latinos diagnosed with HIV infection may vary by Hispanic or Latino subgroup. We analyzed national mortality data from the National Center for Health Statistics for the years 2006 to 2010 to examine differences in HIV-related mortality among Hispanics or Latinos by sociodemographic factors and by Hispanic or Latino subgroup. After adjusting for age, HIV-related death rates per 100,000 population were highest among Hispanics or Latinos who were male (45.6, 95 % confidence interval [CI], 44.4 to 46.9) compared to female (12.0, 95 % CI 11.4 to 12.6), or resided in the Northeast (75.1, 95 % CI 72.2 to 77.9) compared to other US regions at the time of death. The age-adjusted HIV-related death rate was highest among Puerto Ricans (100.9, 95 % CI 97.0 to 104.8) and lowest among Mexicans (16.9, 95 % CI 16.2 to 17.6). Among all deaths, the proportion of HIV-related deaths was more than four times as high among Puerto Ricans (adjusted prevalence ratio = 4.3, 95 % CI 4.1 to 4.5) compared to Mexicans. To ensure better health outcomes for Hispanics or Latinos living with HIV in the USA, medical care and treatment programs should be adapted to address the needs of various Hispanic or Latino subgroups.

Neurocognitive change in the era of HIV combination antiretroviral therapy: the longitudinal CHARTER study

BACKGROUND

Human immunodeficiency virus (HIV)-associated neurocognitive disorders (HAND) can show variable clinical trajectories. Previous longitudinal studies of HAND typically have been brief, did not use adequate normative standards, or were conducted in the context of a clinical trial, thereby limiting our understanding of incident neurocognitive (NC) decline and recovery.

METHODS

We investigated the incidence and predictors of NC change over 16-72 (mean, 35) months in 436 HIV-infected participants in the CNS HIV Anti-Retroviral Therapy Effects Research cohort. Comprehensive laboratory, neuromedical, and NC assessments were obtained every 6 months. Published, regression-based norms for NC change were used to generate overall change status (decline vs stable vs improved) at each study visit. Survival analysis was used to examine the predictors of time to NC change.

RESULTS

Ninety-nine participants (22.7%) declined, 265 (60.8%) remained stable, and 72 (16.5%) improved. In multivariable analyses, predictors of NC improvements or declines included time-dependent treatment status and indicators of disease severity (current hematocrit, albumin, total protein, aspartate aminotransferase), and baseline demographics and estimated premorbid intelligence quotient, non-HIV-related comorbidities, current depressive symptoms, and lifetime psychiatric diagnoses (overall model P < .0001).

CONCLUSIONS

NC change is common in HIV infection and appears to be driven by a complex set of risk factors involving HIV disease, its treatment, and comorbid conditions.

Factors associated with CD8+ T-cell activation in HIV-1-infected patients on long-term antiretroviral therapy

BACKGROUND

Abnormal levels of CD8 T-cell activation persist in HIV-1-infected patients on suppressive antiretroviral therapy (ART) and may be deleterious.

METHODS

CD8 T-cell activation (% coexpressing CD38/HLA-DR) was analyzed on blood specimens from 833 HIV-1-infected patients on ART for ≥96 weeks with concurrent plasma HIV RNA (vRNA) ≤200 copies per milliliter. Factors associated with CD8 T-cell activation were assessed using generalized estimating equations to incorporate longitudinal measurements (median 4/participant).

RESULTS

Participants were 84% men, 47% white, 28% black, and 22% Hispanic, with median pre-ART age 38 years and median ART exposure 144 weeks. CD8 T-cell activation was higher at timepoints when vRNA was 51-200 versus ≤50 copies per milliliter [mean CD8 T-cell activation 23.4% vs. 19.7%; adjusted difference: 1.7% (95% confidence interval: 0.1 to 3.4), P = 0.042]. Restricting to vRNA ≤50 copies per milliliter, multivariable models showed the following factors associated with higher CD8 T-cell activation: older age [≥45 vs. ≤30 years: 3.6% (1.4 to 5.7), P = 0.004], hepatitis C virus antibody positivity [3.6% (0.9 to 6.2), P = 0.032], Hispanic vs. white [7.2% (5.3 to 9.0), P < 0.001], lower concurrent CD4 count [≤200 vs. >500 cells/mm: 2.2% (0.7 to 3.7), P < 0.001], lower concurrent CD4/CD8 ratio [-2.6% (-3.7 to -1.5) per 0.5 unit increase, P < 0.001], and higher pre-ART CD8 T-cell activation [2.0% (1.6 to 2.5) per 10% higher, P < 0.001].

CONCLUSIONS

In participants included in our analysis, residual low-level viremia between 51 and 200 copies per milliliter during ART was shown to be associated with greater CD8 T-cell activation than full suppression to <50 copies per milliliter. Older age, hepatitis C virus antibody positivity, race/ethnicity, higher pre-ART CD8 T-cell activation, and lower concurrent CD4/CD8 ratio and CD4 T-cell count also contribute to greater CD8 T-cell activation during suppressive ART.

HIV treatment as prevention: contradictory perspectives from dynamic mathematical models

The preventative effects of antiretroviral therapy for people with HIV have been debated since they were first raised. Models commenced studying the preventive effects of treatment in the 1990s, prior to initial public reports. However, the outcomes of the preventive effects of antiretroviral use were not consistent. Some outcomes of dynamic models were based on unfeasible assumptions, such as no consideration of drug resistance, behavior disinhibition, or economic inputs in poor countries, and unrealistic input variables, for example, overstated initiation time, adherence, coverage, and efficacy of treatment. This paper reviewed dynamic mathematical models to ascertain the complex effects of ART on HIV transmission. This review discusses more conservative inputs and outcomes relative to antiretroviral use in HIV infections in dynamic mathematical models. ART alone cannot eliminate HIV transmission.

Addressing the HIV/AIDS epidemic among Puerto Rican people who inject drugs: the need for a multiregion approach

High levels of HIV risk behaviors and prevalence have been reported among Puerto Rican people who inject drugs (PRPWID) since early in the HIV epidemic. Advances in HIV prevention and treatment have reduced HIV among people who inject drugs (PWID) in the United States. We examined HIV-related data for PRPWID in Puerto Rico and the US Northeast to assess whether disparities continue. Injection drug use as a risk for HIV is still overrepresented among Puerto Ricans. Lower availability of syringe exchanges, drug abuse treatment, and antiretroviral treatment for PWID in Puerto Rico contribute to higher HIV risk and incidence. These disparities should be addressed by the development of a federally supported Northeast-Puerto Rico collaboration to facilitate and coordinate efforts throughout both regions.

Perspectives on the role of patient-centered medical homes in HIV Care

To strengthen the quality of HIV care and achieve improved clinical outcomes, payers, providers, and policymakers should encourage the use of patient-centered medical homes (PCMHs), building on the Ryan White CARE Act Program established in the 1990s. The rationale for a PCMH with HIV-specific expertise is rooted in clinical complexity, HIV's social context, and ongoing gaps in HIV care. Existing Ryan White HIV/AIDS Program clinicians are prime candidates to serve HIV PCMHs, and HIV-experienced community-based organizations can play an important role. Increasingly, state Medicaid programs are adopting a PCMH care model to improve access and quality to care. Stakeholders should consider several important areas for future action and research with regard to development of the HIV PCMH.

Hispanics, incarceration, and TB/HIV screening: a missed opportunity for prevention

Disparities in incarceration rates and in prison-based TB/HIV testing may contribute to health disparities in the communities most affected by incarceration. We analyzed Bureau of Justice Statistics surveys of federal and state prison inmates to assess TB and HIV screening rates for US-born Hispanics, foreign-born Hispanics, non-Hispanic blacks, and non-Hispanic whites. Screening rates were high overall but foreign-born Hispanic inmates had significantly lower odds of being tested for TB in both state (AOR 0.55) and federal prisons (AOR 0.31) compared to white inmates. Foreign-born Hispanics also had lower odds of being tested for HIV in state prisons and Hispanics had lower odds of being tested for HIV in federal prisons compared to white inmates. Screening for infectious diseases in state and federal prisons is high but Hispanics have higher odds of going untested; this has important consequences for prevention of further transmission in the communities to which they return.

Latinos in the United States on the HIV/AIDS care continuum by birth country/region: a systematic review of the literature

Twenty percent of Latinos with HIV in the US are unaware of their HIV status, 33% are linked to care late, and 74% do not reach viral suppression. Disparities along this HIV/AIDS care continuum may be present between various ethnic groups historically categorised as Latino. To identify differences along the HIV/AIDS care continuum between US Latinos of varying birth countries/regions a systematic review of articles published in English between 2002 and 2013 was conducted using MEDLINE, PsycINFO, and Web of Science. Studies that reported on one or more steps of the HIV/AIDS care continuum and reported results by birth country/region for Latinos were included. Latinos born in Mexico and Central America were found to be at increased risk of late diagnosis compared with US-born Latinos. No studies were found that reported on linkage to HIV care or viral load suppression by country/region of birth. Lower survival was found among Latinos born in Puerto Rico compared with Latinos born in mainland US. Inconsistent differences in survival were found among Latinos born in Mexico, Cuba, and Central America. Socio/cultural context, immigration factors, and documentation status are discussed as partial explanations for disparities along the HIV/AIDS care continuum.

Persistent racial/ethnic disparities in AIDS diagnosis rates among people who inject drugs in U.S. metropolitan areas, 1993-2007

OBJECTIVES

We estimated race/ethnicity-specific incident AIDS diagnosis rates (IARs) among people who inject drugs (PWID) in U.S. metropolitan statistical areas (MSAs) over time to assess the change in disparities after highly active antiretroviral therapy (HAART) dissemination.

METHODS

We compared IARs and 95% confidence intervals (CIs) for black/African American and Hispanic/Latino PWID with those of white PWID in 93 of the most populous MSAs. We selected two three-year periods from the years immediately preceding HAART (1993-1995) and the years with the most recent available data (2005-2007). To maximize stability, we aggregated data across three-year periods, and we aggregated data for black/African American and Hispanic/Latino PWID for most comparisons with data for white PWID. We assessed disparities by comparing IAR 95% CIs for overlap.

RESULTS

IARs were significantly higher for black/African American and Hispanic/Latino PWID than for white PWID in 81% of MSAs in 1993-1995 and 77% of MSAs in 2005-2007. MSAs where disparities became non-significant over time were concentrated in the West. Significant differences were more frequent in comparisons between black/African American and white PWID (85% of MSAs in 1993-1995, 79% of MSAs in 2005-2007) than in comparisons between Hispanic/Latino and white PWID (53% of MSAs in 1993-1995, 56% of MSAs in 2005-2007). IARs declined modestly across racial/ethnic groups in most MSAs.

CONCLUSIONS

AIDS diagnosis rates continue to be substantially higher for black/African American and Hispanic/Latino PWID than for white PWID in most large MSAs. This finding suggests a need for increased targeting of prevention and treatment programs, as well as research on MSA-level conditions that may serve to maintain the disparities.

HIV Prevention Messages Targeting Young Latino Immigrant MSM

Young Latino immigrant men who have sex with men (MSM) are at risk for HIV and for delayed diagnosis. A need exists to raise awareness about HIV prevention in this population, including the benefits of timely HIV testing. This project was developed through collaboration between University of WA researchers and Entre Hermanos, a community-based organization serving Latinos. Building from a community-based participatory research approach, the researchers developed a campaign that was executed by Activate Brands, based in Denver, Colorado. The authors (a) describe the development of HIV prevention messages through the integration of previously collected formative data; (b) describe the process of translating these messages into PSAs, including the application of a marketing strategy; (c) describe testing the PSAs within the Latino MSM community; and (c) determine a set of important factors to consider when developing HIV prevention messages for young Latino MSM who do not identify as gay.

Attitudes towards and Beliefs about HIV Testing among Latino Immigrant MSM: A Comparison of Testers and Nontesters

Latino immigrant men who have sex with men (MSM) are at risk for HIV and delayed diagnosis. An exploratory study using qualitative interviews that assess the beliefs and attitudes of 54 Latino immigrant MSM in Seattle, Washington, is presented. The goal of this research is to determine whether attitudinal differences exist between participants who had and had not been tested and to use any insight into the development of a media campaign to promote testing. Over one-third of the men have never been tested for HIV. Nontesters are more likely to be men who have sex with men and women, have less knowledge about HIV risks, perceive their sexual behaviors as less risky, and deflect HIV-related stigma. Testers are more likely to be self-identified as being gays. Both groups believe that fear of a positive result is the main barrier to testing. Both groups believe that family members have negative attitudes towards HIV testing and that having Latino staff at HIV testing sites hinders confidentiality. Financial concerns with regard to the cost of testing were also expressed by both groups. Based on these insights, recommended strategies for the development of HIV prevention and testing campaigns are made.

Racial/ethnic disparities in antiretroviral treatment among HIV-infected pregnant Medicaid enrollees, 2005-2007

OBJECTIVES

We examined racial/ethnic differences in prenatal antiretroviral (ARV) treatment among 3259 HIV-infected pregnant Medicaid enrollees.

METHODS

We analyzed 2005-2007 Medicaid claims data from 14 southern states, comparing rates of not receiving ARVs and suboptimal versus optimal ARV therapy.

RESULTS

More than one third (37.3%) had zero claims for ARV drugs. Three quarters (73.4%) of 346 Hispanic women received no prenatal ARVs. After we adjusted for covariates, Hispanic women had 3.89 (95% confidence interval = 2.58, 5.87) times the risk of not receiving ARVs compared with Whites. Hispanic women often had only 1 or 2 months of Medicaid eligibility, perhaps associated with barriers for immigrants. Less than 3 months of eligibility was strongly associated with nontreatment (adjusted odds ratio = 29.0; 95% confidence interval = 13.4, 62.7).

CONCLUSIONS

Optimal HIV treatment rates in pregnancy are a public health priority, especially for preventing transmission to infants. Medicaid has the surveillance and drug coverage to ensure that all HIV-infected pregnant women are offered treatment. States that offer emergency Medicaid coverage for only delivery services to pregnant immigrants are missing an opportunity to screen, diagnose, and treat pregnant women with HIV, and to prevent HIV in children.

Disparities in engagement in care and viral suppression among persons with HIV

BACKGROUND

Engagement across the spectrum of HIV care can improve health outcomes and prevent HIV transmission. We used HIV surveillance data to examine these outcomes.

METHODS

San Francisco residents who were diagnosed with HIV between 2009 and 2010 were included. We measured the characteristics and proportion of persons linked to care within 6 months of diagnosis, retained in care for second and third visits, and virally suppressed within 12 months of diagnosis.

RESULTS

Of 862 persons included, 750 (87%) entered care within 6 months of diagnosis; of these, 72% had a second visit in the following 3-6 months; and of these, 80% had a third visit in the following 3-6 months. Viral suppression was achieved in 50% of the total population and in 76% of those retained for 3 visits. Lack of health insurance and unknown housing status were associated with not entering care (P < 0.01). Persons with unknown insurance status were less likely to be retained for a second visit; those younger than 30 years were less likely to be retained for a third visit. Independent predictors of failed viral suppression included age <40 years, homelessness, unknown housing status, and having a single or 2 medical visits compared with 3 visits.

CONCLUSIONS

Socioeconomic resources and age, not race or gender, are associated with disparities in engagement in HIV care in San Francisco.

Stigma and racial/ethnic HIV disparities: moving toward resilience

Prior research suggests that stigma plays a role in racial/ethnic health disparities. However, there is limited understanding about the mechanisms by which stigma contributes to HIV-related disparities in risk, incidence and screening, treatment, and survival and what can be done to reduce the impact of stigma on these disparities. We introduce the Stigma and HIV Disparities Model to describe how societal stigma related to race and ethnicity is associated with racial/ethnic HIV disparities via its manifestations at the structural level (e.g., residential segregation) as well as the individual level among perceivers (e.g., discrimination) and targets (e.g., internalized stigma). We then review evidence of these associations. Because racial/ethnic minorities at risk of and living with HIV often possess multiple stigmas (e.g., HIV-positive, substance use), we adopt an intersectionality framework and conceptualize interdependence among co-occurring stigmas. We further propose a resilience agenda and suggest that intervening on modifiable strength-based moderators of the association between societal stigma and disparities can reduce disparities. Strengthening economic and community empowerment and trust at the structural level, creating common ingroup identities and promoting contact with people living with HIV among perceivers at the individual level, and enhancing social support and adaptive coping among targets at the individual level can improve resilience to societal stigma and ultimately reduce racial/ethnic HIV disparities.

Perceived discrimination and physical health among HIV-positive Black and Latino men who have sex with men

We conducted the first study to examine health correlates of discrimination due to race/ethnicity, HIV-status, and sexual orientation among 348 HIV-positive Black (n = 181) and Latino (n = 167) men who have sex with men. Participants completed audio computer-assisted self-interviews. In multivariate analyses, Black participants who experienced greater racial discrimination were less likely to have a high CD4 cell count [OR = 0.7, 95 % CI = (0.5, 0.9), p = 0.02], and an undetectable viral load [OR = 0.8, 95 % CI = (0.6, 1.0), p = 0.03], and were more likely to visit the emergency department [OR = 1.3, 95 % CI = (1.0, 1.7), p = 0.04]; the combined three types of discrimination predicted greater AIDS symptoms [F (3,176) = 3.8, p < 0.01]. Among Latinos, the combined three types of discrimination predicted greater medication side effect severity [F (3,163) = 4.6, p < 0.01] and AIDS symptoms [F (3,163) = 3.1, p < 0.05]. Findings suggest that the stress of multiple types of discrimination plays a role in health outcomes.

The Hispanic HIV Epidemic

The Hispanic population in the U.S. has been dramatically affected by the HIV epidemic. The impact not only is related to the infection itself and its complications, but also is driven by social factors that lead to increased disparity in health-care access and cultural modeling and to increased social stigma, which leads to marginalization and exacerbates the existing gaps in medical care. Hispanics infected with HIV more frequently receive delayed diagnoses and more often present with AIDS, concomitant opportunistic infections, or coinfections related to their country of origin. The unique characteristics that define the HIV epidemic in Hispanics need further analysis in order to identify new opportunities to improve linkage to health care, increase efficacy in health-care provision, and decrease social disparities related to the Hispanic population.

HIV testing behaviors among Latinos in Baltimore City

In the US, HIV disproportionately affects Latinos who often present late in the disease. Baltimore has seen a recent rapid growth in its Latino population paralleled by an increasing impact of HIV/AIDS among Latinos. From 2009 to 2010, we performed a cross-sectional survey of Latinos accessing the Baltimore City Health Department (BCHD) Latino Outreach services to assess self-report of previous HIV testing, with particular attention to migration history and risk behaviors. Of 247 Latinos (46% male) accessing BCHD outreach services, 96% were foreign-born. Self-perceived HIV risk was not associated with actual risk behaviors or HIV testing. In multivariate models, previous HIV testing was correlated with knowledge of HIV transmission modes and knowing that a person with HIV can appear healthy. Consistent with CDC recommendations, HIV screening among Latino immigrants should not be limited to individuals with self-perceived risk for HIV. Promoting key pieces of HIV knowledge may improve HIV testing behaviors.

Stressors and sources of support: the perceptions and experiences of newly diagnosed Latino youth living with HIV

Little is known of the experience of Latino youth with HIV infection in the United States, especially with respect to stressors and how these youth cope with said stressors. This study reports on a subset (Latino/Hispanic self-identified youth, n=14) of qualitatively interviewed youth (n=30), both in individual interviews and in focus group discussion settings, aware of their HIV diagnosis for 12-24 months (mean: 16.7 months; standard deviation [SD], 4.89) Youth were 16-24 years old (M=21.5 years), female (43%) and males (57%). Youth were recruited from three cities: Chicago, New York, and San Juan (Puerto Rico). Interviews of Latinos (n=14) were reviewed for sources of stressors and support. Seven themes emerged in analyzing stated sources of stressors: (1) initial psychosocial responses to HIV diagnosis, (2) disclosure to family and friends, (3) stigma related to receiving an HIV diagnosis, (4) body image and concerns of the physical changes associated with HIV and antiretroviral medications, (5) taking antiretroviral medications and side effects, (6) the disruption of their future life goals, and (7) reproductive health concerns. Identified sources of support and coping were described including; gaining appreciation for what matters in life, adapting and developing achievable goals, reordering priorities and relying on religion and spiritual beliefs for health outcomes. The information gathered is from individual interviews and from focus group discussions can be used to increase the understanding of this understudied population while improving services to engage and retain these youth in care.

Prevalence of Drug Resistance and Associated Mutations in a Population of HIV-1(+) Puerto Ricans: 2006-2010

This is a continuation of our efforts to maintain a record of the evolution of HIV-1 infection in Puerto Rico by monitoring the expression levels of antiretroviral drug-resistance-associated mutations. Samples from 2,500 patients from 2006–2010 were analyzed using the TruGene HIV-1 genotyping kit and the OpenGene DNA sequencing system. Results show that 58.8% of males and 65.3% of females had HIV-1 with resistance to at least one medication. The average number of HIV mutations was 6.0 in males and 6.1 in females. Statistically significant differences between men and women were recorded in the levels of HIV-1 expressed mutations and antiretroviral drug resistance. The most prevalent antiretroviral medication resistance shifted from zalcitabine to nevirapine and efavirenz in the five-year period. M184V and L63P were the dominant mutations for the reverse transcriptase and the protease genes, respectively, but an increase in the incidence of minority mutations was observed.

Race and CD4+ T-cell count in HIV prognosis and treatment

CD4+ T-cell count is known to vary by race in HIV-negative individuals. While people of certain races, such as blacks and Asians, continue to be disproportionately burdened by HIV/AIDS, they remain under-represented in most HIV clinical studies. Recent studies suggest that CD4+ count evolution in HIV, before and after therapy, may differ by race. In this review, we summarize the evidence from prospective cohorts comparing CD4+ count trajectories by race, and whether it is of any clinical significance. We find that although minor differences in CD4+ count trajectories exist between people of diverse races, socioeconomic, cultural and environmental differences are far more important in predicting clinical outcomes than racial differences in CD4+ count. Furthermore, current evidence does not support the need for any race or ethnicity-specific CD4+ thresholds for ART and prophylactic therapy initiation. Future long-term trials in racially diverse populations are required to substantiate these findings.

Disparities among US states in HIV-related mortality in persons with HIV infection, 2001-2007

OBJECTIVE

To examine interstate variation in US HIV case-fatality rates, and compare them with corresponding conventional HIV death rates.

DESIGN

Cross-sectional analysis using data on deaths due to HIV infection from the National Vital Statistics System and data on persons 15 years or older living with HIV infection in 2001-2007 in 37 US states from the national HIV/AIDS Reporting System.

METHODS

State rankings by age-adjusted HIV case-fatality rates (with HIV-infected population denominators) were compared with rankings by conventional death rates (with general population denominators). Negative binomial regression determined case-fatality rate ratios among states, adjusted for age, sex, race/ethnicity, year, and state-level markers of late HIV diagnosis.

RESULTS

On the basis of 3,096,729 HIV-infected person-years, the overall HIV case-fatality rate was 20.6 per 1000 person-years [95% confidence interval (CI) 20.3-20.9]. Age-adjusted rates by state ranged from 9.6 (95% CI 6.8-12.4) in Idaho to 32.9 (95% CI 29.8-36.0) in Mississippi, demonstrating significant differences across states, even after adjusting for race/ethnicity (P < 0.0001). Many states with low conventional death rates had high case-fatality rates. Nine of the 10 states with the highest case-fatality rates were located in the southern United States.

CONCLUSION

Case-fatality rates complement and are not entirely concordant with conventional death rates. Interstate differences in these rates may reflect differences in secondary and tertiary prevention of HIV-related mortality among infected persons. These data suggest that state-specific contextual barriers to care may impede improvements in quality and disparities of healthcare without targeted interventions.
