Abstract
Background Restricted mean survival time (RMST) is an underutilized estimand in time-to-event analyses. Herein, we highlight its strengths by comparing time to (1) all-cause mortality and (2) initiation of antiretroviral therapy (ART) for HIV-infected persons who inject drugs (PWID) and persons who do not inject drugs. Methods RMST to death was determined by integrating the Kaplan-Meier survival curve to 5 years of follow-up. To account for the competing risks of death and loss-to-clinic when estimating time to ART, we calculated RMST to ART initiation by estimating the area between the survival curve for ART initiation and the cumulative incidence curve for death or loss-to-clinic. We standardized all curves using inverse probability of exposure weights. Results We followed 3044 HIV-positive, ART-naive persons from enrollment into the Johns Hopkins HIV Clinical Cohort from 1996 to 2014. PWID had a − 0.19 year (95% confidence interval (CI): − 0.29, − 0.10) difference in survival over 5 years of follow-up compared to persons who did not inject drugs. There was no difference between the two groups in time not on ART while alive and in clinic (RMST difference = 0.08, 95% CI: -0.10, 0.36). Conclusions PWID have similar expected time to ART initiation after properly accounting for their greater risk of death and loss-to-clinic.

Abstract
BACKGROUND Although antiretroviral therapy (ART) is available to treat HIV+ persons and prevent transmission, ineffective delivery of care may delay ART use, impede viral suppression (VS), and contribute to racial/ethnic disparities along the continuum of care. This study tested the effects of a bi-directional laboratory health information exchange (LHIE) intervention on each of these outcomes. METHODS We used a quasi-experimental, interrupted time-series design to examine whether the LHIE intervention improved ART use and VS, and reduced racial/ethnic disparities in these outcomes among HIV+ patients (N = 1181) in a comprehensive HIV/AIDS clinic in Southern California. Main outcome measures were ART pharmacy fill and HIV viral load laboratory data extracted from the medical records over 3 years. Race/ethnicity and an indicator for the intervention (after vs. before) were the main predictors. The analysis involved 3-stage, multivariable logistic regression with generalized estimating equations. RESULTS Overall, the intervention predicted greater odds of ART use (odds ratio [OR] = 2.50; 95% confidence interval: 2.29 to 2.73; P < 0.001) and VS (OR = 1.12; 95% confidence interval: 1.04 to 1.21; P < 0.05) in the final models that included sociodemographic, behavioral, and clinical covariates. Before the intervention, there were significant black/white disparities in ART use OR = 0.75 (0.58-0.98; P = 0.04) and VS OR = 0.75 (0.61-0.92; P = 0.001). After the intervention, the black/white disparities decreased after adjusting for sociodemographics and the number of HIV care visits, and Latinos had greater odds than whites of ART use and VS, adjusting for covariates. CONCLUSIONS The intervention improved overall ART treatment and VS, and reduced black/white disparities. LHIE interventions may hold promise if implemented among similar patients.

Abstract
Early antiretroviral therapy (ART) initiation reduces the risk of disease progression and HIV transmission, but data on time from HIV care entry to ART initiation are lacking. Using data from the Medical Monitoring Project (MMP), a population-based probability sample of HIV-infected adults receiving medical care in the United States, we assessed time from care entry to ART initiation among persons diagnosed May 2004-April 2009 and used multivariable Cox proportional-hazards models to identify factors associated with time to ART initiation. Among 1094 MMP participants, 83.9% reported initiating ART, with median time to ART initiation of 10 months. In multivariable models, blacks compared to whites [hazard ratio (HR) 0.82; 95% confidence interval (CI) 0.70-0.98], persons without continuous health insurance (HR 0.82; CI 0.70-0.97), heterosexual women and men who have sex with men compared to heterosexual men (HR 0.66; CI 0.51-0.85 and HR 0.71; CI 0.60-0.84, respectively), and persons without AIDS at care entry (HR 0.37; CI 0.31-0.43) had significantly longer times to ART initiation. Overall, time to ART initiation was suboptimal by current standards and significant disparities were noted among certain subgroups. Efforts to encourage prompt ART initiation should address delays among those without health insurance and among certain sociodemographic subgroups.

Abstract
OBJECTIVES We examined whether the timely initiation of antiretroviral therapy (ART) differed by race and comorbidity among older (≥ 50 years) people living with HIV/AIDS (PLWHA). METHODS We conducted frequency and descriptive statistics analysis to characterize our sample, which we drew from 2005-2007 Medicaid claims data from 14 states. We employed univariate and multivariable Cox regression analyses to evaluate the relationship between race, comorbidity, and timely ART initiation (≤ 90 days post-HIV/AIDS diagnosis). RESULTS Approximately half of the participants did not commence ART promptly. After we adjusted for covariates, we found that older PLWHA who reported a comorbidity were 40% (95% confidence interval = 0.26, 0.61) as likely to commence ART promptly. We found no racial differences in the timely initiation of ART among older PLWHA. CONCLUSIONS Comorbidities affect timely ART initiation in older PLWHA. Older PLWHA may benefit from integrating and coordinating HIV care with care for other comorbidities and the development of ART treatment guidelines specific to older PLWHA. Consistent Medicaid coverage helps ensure consistent access to HIV treatment and care and may eliminate racial disparities in timely ART initiation among older PLWHA.

Abstract
BACKGROUND Monitoring of immune function, measured by CD4 cell count, is an essential service for people with Human Immunodeficiency Virus (HIV). Prescription of antiretroviral (ARV) medications is contingent on CD4 cell count; patients without regular CD4 monitoring are unlikely to receive ARVs when indicated. This study assesses disparities in CD4 monitoring among HIV-positive Medicaid beneficiaries. METHODS In this retrospective observational study, we examined 24 months of administrative data on 2,250 HIV-positive, continuously-enrolled fee-for-service Medicaid beneficiaries with at least two outpatient healthcare encounters. We used logistic regression to evaluate the association of patient demographics (age, gender, race/ethnicity, and language) with receipt of at least one CD4 test per year, controlling for other potentially confounding variables. RESULTS Having a history of ARV therapy was positively associated with receipt of CD4 tests. We found racial/ethnic, gender, and age disparities in CD4 testing. Among individuals with a history of ARV use, all racial/ethnic groups were significantly less likely to have CD4 tests than White non-Latinos (African Americans, OR = 0.35, p<0.0001; Asian/Pacific Islanders, OR = 0.31, p=0.0047; and, Latinos, OR = 0.42, p<0.0001). CONCLUSIONS Disparities in receipt of CD4 tests elucidate one potential pathway for previously reported disparities in ARV treatment. Further qualitative and quantitative research is needed to identify the specific factors that account for these disparities, so that appropriate interventions can be implemented.

Abstract
OBJECTIVES We determined hospitalization rates and disparities among people with HIV, which may have been underestimated in previous studies, as only those in medical care were included. METHODS We estimated the hospitalization rate of people with diagnosed HIV infection in the U.S. in 2009 using two nationally representative datasets. We took the number of hospitalizations from the Nationwide Inpatient Sample and searched each discharge for International Classification of Diseases, Ninth Revision codes for HIV infection and opportunistic infections (OIs). We divided the number of hospitalizations by the number of prevalent diagnosed HIV cases estimated by CDC to produce hospitalization rates, and then compared those rates using Z-tests. RESULTS The estimated nationwide hospitalization rate was 26.6 per 100 population. Women had a 51% higher rate than men (35.5 vs. 23.5 per 100 population, p=0.002). Black people (31.2 per 100 population, p=0.01) had a 42% higher rate, and Hispanic people (18.2 per 100 population, p=0.23) had an 18% lower rate than white people (22.1 per 100 population) of hospitalization for any illness. Of hospitalizations with an OI, females with HIV had a 50% higher rate than males with HIV (5.0 vs. 3.4 per 100 population, p=0.003). Black people with HIV (4.7 per 100 population, p<0.001) had a 72% higher rate and Hispanic people with HIV (2.9 per 100 population, p=0.78) had a similar rate of hospitalization with an OI compared with white people with HIV (2.7 per 100 population). CONCLUSIONS Hospitalization rates among people living with HIV in the U.S. are higher than have been previously estimated. Substantial gender and racial/ethnic disparities in hospitalization rates exist, suggesting that the benefits of antiretroviral therapy have not been realized across all groups equally.

Abstract
BACKGROUND The purpose of this study was to update the epidemiological data on the prevalence of coinfection with hepatitis C virus (HCV) and HIV, and to identify whether specific clinical and epidemiological factors influenced the response of HIV-positive adults to highly active antiretroviral therapy (HAART). METHODS This retrospective observational cohort study of 238 HIV-infected patients evaluated the effect of different epidemiological and clinical parameters (including HCV coinfection) on therapy response among HIV-infected adults initiating HAART. Multiple logistic regression models were used to identify factors associated with therapy response and estimated risk coefficients. RESULTS Seroprevalence of HCV infection in this population was 26% (62/238). We did not observe a significant association between immunological or virological response relating to patient gender or HAART regimen. However, this analysis showed that HCV serological status, age at HIV diagnosis, duration of treatment and WHO clinical stage of AIDS (<200 CD4 cells/ml independently of viral load either < or > to 100,000 copies/ml), were significantly associated with immunological and virological responses to HAART. CONCLUSIONS These results show further evidence that hepatitis C serostatus is associated with a reduced response to HAART.

Abstract
Racial/ethnic disparities in HIV infection, with minority groups typically having higher rates of infection, are a formidable public health challenge. In the United States, among both men and women who inject drugs, HIV infection rates are elevated among Hispanics and non-Hispanic Blacks. A meta-analysis of international research concluded that among persons who inject drugs, racial and ethnic minorities were twice as likely to acquire an HIV infection, though there was great variation across the individual studies. To examine strategies to reduce racial/ethnic disparities among persons who inject drugs, we reviewed studies on injection drug use and its role in HIV transmission. We identified four sets of evidence-based interventions that may reduce racial/ethnic disparities among persons who inject drugs: HIV counseling and testing, risk reduction services, access to antiretroviral therapy, and drug abuse treatment. Implementation of these services, however, is insufficient in many countries, including the United States. Persons who inject drugs appear to be changing drug use norms and rituals to reduce their risks. The challenges are to (a) develop a validated model of how racial/ethnic disparities in HIV infection arise, persist, and are reduced or eliminated over time and (b) implement evidence-based services on a sufficient scale to eliminate HIV transmission among all persons who inject drugs.

Abstract
OBJECTIVES We described the racial/ethnic disparities in survival among people diagnosed with AIDS in Florida from 1993 to 2004, as the availability of highly active antiretroviral therapy (HAART) became widespread. We determined whether these disparities decreased after controlling for measures of community-level socioeconomic status. METHODS We compared survival from all causes between non-Hispanic Blacks and non-Hispanic Whites vis-a-vis survival curves and Cox proportional hazards models controlling for demographic, clinical, and area-level poverty factors. RESULTS Racial/ethnic disparities in survival peaked for those diagnosed during the early implementation of HAART (1996-1998) with a Black-to-White hazard ratio (HR) of 1.72 (95% confidence interval [CI] = 1.62, 1.83) for males and 1.40 (95% CI = 1.24, 1.59) for females. These HRs declined significantly to 1.48 (95% CI = 1.35, 1.64) for males and nonsignificantly to 1.25 (95% CI = 1.05, 1.48) for females in the 2002 to 2004 diagnosis cohort. Disparities decreased significantly for males but not females when controlling for baseline demographic factors and CD4 count and percentage, and became nonsignificant in the 2002 to 2004 cohort after controlling for area poverty. CONCLUSIONS Area poverty appears to play a role in racial/ethnic disparities even after controlling for demographic factors and CD4 count and percentage.

Abstract
Rural persons with HIV face barriers to care that may influence adoption of advances in therapy. We performed a retrospective cohort study to determine rural-urban variation in adoption of raltegravir-the first HIV integrase inhibitor-in national Veterans Affairs (VA) healthcare. There were 1,222 veterans with clinical indication for raltegravir therapy at time of its FDA approval in October 2007, of whom 223 (19.1%) resided in rural areas. Urban persons were more likely than rural to initiate raltegravir within 180 days (17.3% vs. 11.2%, P = 0.02) and 360 days (27.5% vs. 19.7%, P = 0.02), but this gap narrowed slightly at 720 days (36.3% vs. 31.8%, P = 0.19). In multivariable analysis adjusting for patient characteristics, urban residence predicted raltegravir adoption within 180 days (odds ratio 1.72, 95% CI 1.09-2.70) and 360 days (OR 1.63, 95% CI 1.13-2.34), but not 720 days (OR 1.26, 95% CI 0.84-1.87). Efforts are needed to reduce geographic variation in adoption of advances in HIV therapy.

Abstract
Trauma and posttraumatic stress disorder disproportionally affect HIV-positive women. Studies increasingly demonstrate that both conditions may predict poor HIV-related health outcomes and transmission-risk behaviors. This study analyzed data from a prevention-with-positives program to understand if socio-economic, behavioral, and health-related factors are associated with antiretroviral failure and HIV transmission-risk behaviors among 113 HIV-positive biological and transgender women. An affirmative answer to a simple screening question for recent trauma was significantly associated with both outcomes. Compared to participants without recent trauma, participants reporting recent trauma had over four-times the odds of antiretroviral failure (AOR 4.3; 95% CI 1.1-16.6; p = 0.04), and over three-times the odds of reporting sex with an HIV-negative or unknown serostatus partner (AOR 3.9; 95% CI 1.3-11.9; p = 0.02) and <100% condom use with these partners (AOR 4.5; 95% CI 1.5-13.3; p = 0.007). Screening for recent trauma in HIV-positive biological and transgender women identifies patients at high risk for poor health outcomes and HIV transmission-risk behavior.

Abstract
OBJECTIVE Prior research has documented sociodemographic disparities in the use of antiretroviral therapy (ART). Recent therapeutic developments and changing epidemiological profiles may have altered such disparities. We examine the extent to which sociodemographic differences in prescribed ART have changed between 2002 and 2008. METHODS We analyzed data abstracted from medical records at 13 US sites participating in the Human Immunodeficiency Virus Research Network. Prescription of ART was assessed for each year in care for each patient. A total of 14,092 patients were followed up for 39,251 person-years. We examined ART use as a function of sex, race/ethnicity, human immunodeficiency virus risk group, age, and CD4 history (no test <500 cells/mm, one or more tests between 500 and 350 cells/mm, 1 test ≤350 cells/mm, and 2 or more tests ≤350 cells/mm). Using multiple logistic regression, we ascertained interactions between each of these variables and calendar year. RESULTS The overall percentage prescribed ART increased from 60% to 80% between 2002 and 2008. Among those with 2 or more CD4 tests ≤350 cells/mm, the percentage increased from 82% to 92%. ART rates were higher for those with lower CD4 counts but increased over time for all CD4 groups and for all demographic groups. Nevertheless, sex and racial/ethnic disparities persisted. Significant interactions were obtained for CD4 history by year, age by year, and age by CD4 history. CONCLUSIONS Although prescription of ART became more widespread from 2002 to 2008, patients who were female, black, or younger still had lower ART rates than male, white, or older patients.

We assessed the impact of receiving care at an adult or pediatric HIV clinical site on initiation and discontinuation of the first HAART regimen in behaviorally infected youth (BIY). METHODS This was a retrospective analysis of treatment-naive BIY, aged 12-24 years, who enrolled in the HIV Research Network between 2002 and 2008 and who met criteria for HAART. The outcomes were time from meeting criteria to initiation of HAART and time to discontinuation of the first HAART regimen. Analyses were conducted using Cox proportional hazards regression. RESULTS Of 287 treatment-eligible youth, 198 (69%) received HAART; of these 198 youth, 58 (29.3%) subsequently discontinued HAART. In multivariable analyses, there was no significant difference in the time between meeting treatment criteria and initiating HAART for BIY followed at adult or pediatric HIV clinical sites. However, BIY followed at adult sites discontinued HAART sooner than BIY followed at pediatric HIV clinical sites (adjusted hazard ratio [AHR]: 3.19 [1.26-8.06]). CONCLUSIONS Two-thirds of treatment-eligible BIY in the HIV Research Network cohort initiated HAART; however, one-third who initiated HAART discontinued it during the study period. Identifying factors associated with earlier HAART initiation and sustainability can inform interventions to enhance HAART utilization among treatment-eligible youth. The finding of earlier HAART discontinuation for youth at adult care sites deserves further study.

Norton WE. An exploratory study to examine intentions to adopt an evidence-based HIV linkage-to-care intervention among state health department AIDS directors in the United States. Implement Sci 2012; 7:27. [PMID: 22471965 PMCID: PMC3348078 DOI: 10.1186/1748-5908-7-27] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2011] [Accepted: 04/02/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Widespread dissemination and implementation of evidence-based human immunodeficiency virus (HIV) linkage-to-care (LTC) interventions is essential for improving HIV-positive patients' health outcomes and reducing transmission to uninfected others. To date, however, little work has focused on identifying factors associated with intentions to adopt LTC interventions among policy makers, including city, state, and territory health department AIDS directors who play a critical role in deciding whether an intervention is endorsed, distributed, and/or funded throughout their region. METHODS Between December 2010 and February 2011, we administered an online questionnaire with state, territory, and city health department AIDS directors throughout the United States to identify factors associated with intentions to adopt an LTC intervention. Guided by pertinent theoretical frameworks, including the Diffusion of Innovations and the "push-pull" capacity model, we assessed participants' attitudes towards the intervention, perceived organizational and contextual demand and support for the intervention, likelihood of adoption given endorsement from stakeholder groups (e.g., academic researchers, federal agencies, activist organizations), and likelihood of enabling future dissemination efforts by recommending the intervention to other health departments and community-based organizations. RESULTS Forty-four participants (67% of the eligible sample) completed the online questionnaire. Approximately one-third (34.9%) reported that they intended to adopt the LTC intervention for use in their city, state, or territory in the future. Consistent with prior, related work, these participants were classified as LTC intervention "adopters" and were compared to "nonadopters" for data analysis. Overall, adopters reported more positive attitudes and greater perceived demand and support for the intervention than did nonadopters. Further, participants varied with their intention to adopt the LTC intervention in the future depending on endorsement from different key stakeholder groups. Most participants indicated that they would support the dissemination of the intervention by recommending it to other health departments and community-based organizations. CONCLUSIONS Findings from this exploratory study provide initial insight into factors associated with public health policy makers' intentions to adopt an LTC intervention. Implications for future research in this area, as well as potential policy-related strategies for enhancing the adoption of LTC interventions, are discussed.

Abstract
Background Personal health records (PHR) may improve patients' health by providing access to and context for health information. Among patients receiving care at a safety-net HIV/AIDS clinic, we examined the hypothesis that a mental health (MH) or substance use (SU) condition represents a barrier to engagement with web-based health information, as measured by consent to participate in a trial that provided access to personal (PHR) or general (non-PHR) health information portals and by completion of baseline study surveys posted there. Methods Participants were individually trained to access and navigate individualized online accounts and to complete study surveys. In response to need, during accrual months 4 to 12 we enhanced participant training to encourage survey completion with the help of staff. Using logistic regression models, we estimated odds ratios for study participation and for survey completion by combined MH/SU status, adjusted for levels of computer competency, on-study training, and demographics. Results Among 2,871 clinic patients, 70% had MH/SU conditions, with depression (38%) and methamphetamine use (17%) most commonly documented. Middle-aged patients and those with a MH/SU condition were over-represented among study participants (N = 338). Survey completion was statistically independent of MH/SU status (OR, 1.85 [95% CI, 0.93–3.66]) but tended to be higher among those with MH/SU conditions. Completion rates were low among beginner computer users, regardless of training level (<50%), but adequate among advanced users (>70%). Conclusions Among patients attending a safety-net clinic, MH/SU conditions were not barriers to engagement with web-based health information. Instead, level of computer competency was useful for identifying individuals requiring substantial computer training in order to fully participate in the study. Intensive on-study training was insufficient to enable beginner computer users to complete study surveys.

Abstract
OBJECTIVES Increasing numbers of youth are becoming HIV-infected and need highly active antiretroviral therapy (HAART). We hypothesized that behaviorally HIV-infected youth (BIY) ages 18 to 24 years are less likely than adults (25 years or older) to receive HAART and, once initiated, more likely to discontinue their first HAART regimen. METHODS Longitudinal analysis of treatment-naïve patients (age 18 years or older) meeting criteria for HAART and followed at HIV Research Network sites (2002-2008). Time from meeting criteria to HAART initiation and duration on first regimen were assessed using Cox proportional hazards regression. RESULTS A total of 3127 (268 youth, 2859 adult) treatment-naïve, HIV-infected patients met criteria. BIY were more likely to be black (66.8% vs 51.1%; P < 0.01) and less likely to identify injection drug use HIV risk (1.1% vs 8.8%; P < 0.01) than adults 25 years of age or older. Nearly 69% of BIY started HAART versus 79% of adults (P < 0.001). Adults 25 to 29 years of age (adjusted hazards ratio [AHR], 1.39; 95% confidence interval [CI], 1.12-1.73) and 50 years of age or older (AHR, 1.24; 95% CI, 1.00-1.54), but not 30 to 49 years (AHR, 1.19; 95% CI, 0.99-1.44) were more likely to initiate HAART than BIY. Attending four or more HIV provider visits within 1 year of meeting criteria was associated with HAART initiation (AHR, 1.91; 1.70-2.14). CD4 200 to 350 versus less than 200 cells/mm (AHR, 0.57; 95% CI, 0.52-0.63), and injection drug use (AHR, 0.80; 95% CI, 0.69-0.92) were associated with a lower likelihood of HAART initiation. There were no age-related differences in duration of the first regimen. CONCLUSION BIY are less likely to start HAART when meeting treatment criteria. Addressing factors associated with this disparity is critical to improving care for youth.

Abstract
OBJECTIVES We sought state-level factors associated with the adoption of medications to treat mental health conditions on state formularies for the AIDS Drug Assistance Program. METHODS We interviewed 22 state and national program experts and identified 7 state-level factors: case burden, federal dollar-per-case Ryan White allocation size, political orientation, state wealth, passage of a mental health parity law, number of psychiatrists per population, and size of mental health budget. We then used survival analysis to test whether the factors were associated with faster adoption of psychotropic drugs from 1997 to 2008. RESULTS The relative size of a state's federal Ryan White HIV/AIDS Program allocation, the state's political orientation, and its concentration of psychiatrists were significantly associated with time-to-adoption of psychotropic drugs on state AIDS Drug Assistance Program formularies. CONCLUSIONS Substantial heterogeneity exists across states in formulary adoption of drugs to treat mental illness. Understanding what factors contribute to variation in adoption is vital given the importance of treating mental health conditions as a component of comprehensive HIV care.

Abstract
In this era of effective antiretroviral therapy, early diagnosis of HIV and timely linkage to and retention in care are vital to survival and quality of life. Federal guidelines recommend regular monitoring of HIV-related laboratory parameters and initiation of antiretroviral treatment at specified thresholds. We used routinely reported laboratory data to measure intervals between visits by New York City residents newly diagnosed with HIV July 1 to September 30, 2005, and initiating care within 3 months of diagnosis. We measured regular care (≥1 visit every 6 months) and retention in care (last visit ≤6 months before close of analysis) through June 30, 2009. Patients were followed for 45-48 months. Seventy-seven percent (650/842) of patients initiated care within 3 months of diagnosis; 609 (93.7%) made at least one subsequent visit; 45.4% had regular care. Risk factors for not receiving regular care included age 13-24 versus 50+ (adjusted odds ratio [AOR] 3.0, 95% confidence interval [CI] 1.5, 6.0), black race (AOR 2.0, 95% CI 1.4,2.8), eligibility for antiretroviral treatment (AOR 1.5, 95% CI 1.1, 2.2), and injection drug use (IDU; AOR = 2.7. 95% CI 1.0, 7.1). In a time-to-event analysis, risk factors for loss to care were age 13-24 versus 50+ at diagnosis (adjusted hazard ratio [AHR] 1.9, 95% CI 1.1, 3.4), non-hospital site of care (AHR 1.4, 95% CI 1.0, 2.0) and early stage (non-AIDS) disease (AHR 1.4, 95% CI 1.0, 2.0). The analysis demonstrates how mandated reporting of HIV-related laboratory tests provides surveillance systems with the capacity to monitor utilization of care, identify deficits, and evaluate progress in programs designed to facilitate retention in care.

Abstract
BACKGROUND It is unknown whether sex and race influence clinical outcomes following primary human immunodeficiency virus type 1 (HIV-1) infection. METHODS Data were evaluated from an observational, multicenter, primarily North American cohort of HIV-1 seroconverters. RESULTS Of 2277 seroconverters, 5.4% were women. At enrollment, women averaged .40 log₁₀ fewer copies/mL of HIV-1 RNA (P < .001) and 66 more CD4(+) T cells/μL (P = .006) than men, controlling for age and race. Antiretroviral therapy (ART) was less likely to be initiated at any time point by nonwhite women and men compared to white men (P < .005), and by individuals from the southern United States compared to others (P = .047). Sex and race did not affect responses to ART after 6 months (P > .73). Women were 2.17-fold more likely than men to experience >1 HIV/AIDS-related event (P < .001). Nonwhite women were most likely to experience an HIV/AIDS-related event compared to all others (P = .035), after adjusting for intravenous drug use and ART. Eight years after diagnosis, >1 HIV/AIDS-related event had occurred in 78% of nonwhites and 37% of whites from the southern United States, and 24% of whites and 17% of nonwhites from other regions (P < .001). CONCLUSIONS Despite more favorable clinical parameters initially, female HIV-1-seroconverters had worse outcomes than did male seroconverters. Elevated morbidity was associated with being nonwhite and residing in the southern United States.

Abstract
BACKGROUND The overall burden of cancer may increase as individuals with acquired immunodeficiency syndrome (AIDS) live longer because of highly active antiretroviral therapy (HAART), which has been widely available since 1996. METHODS A population-based, record-linkage study identified cancers in 472,378 individuals with AIDS from 1980 to 2006. By using nonparametric competing-risk methods, the cumulative incidence of cancer was estimated across 3 calendar periods (AIDS onset in 1980-1989, 1990-1995, and 1996-2006). RESULTS Measured at 5 years after AIDS onset, the cumulative incidence of AIDS-defining cancer (ADC) declined sharply across the 3 AIDS calendar periods (from 18% in 1980-1989, to 11% in 1990-1995, to 4.2% in 1996-2006 [ie, the HAART era]). The cumulative incidence of Kaposi sarcoma declined from 14.3% during 1980 to 1989, to 6.7% during 1990 to 1995, and to 1.8% during 1996 to 2006. The cumulative incidence of non-Hodgkin lymphoma (NHL) declined from 3.8% during 1990 through 1995 to 2.2% during 1996 through 2006; during the HAART era, NHL was the most common ADC (53%). The cumulative incidence of non-AIDS-defining cancer (NADC) increased from 1.1% to 1.5% with no change thereafter (1%; 1996-2006), in part because of declines in competing mortality. However, cumulative incidence increased steadily over time for specific NADCs (anal cancer, Hodgkin lymphoma, and liver cancer). The cumulative incidence of lung cancer increased from 0.14% during 1980 to 1989 to 0.32% during 1990 to 1995, and no change was observed thereafter. CONCLUSIONS Dramatically declining cumulative incidence was noted in 2 major ADCs (Kaposi sarcoma and NHL), and increases were observed in some NADCs (specifically, cancers of the anus, liver, and lung and Hodgkin lymphoma). As HIV/AIDS is increasingly managed as a chronic disease, greater attention should be focused on cancer screening and prevention.

Abstract
BACKGROUND Persons living with AIDS today remain at elevated cancer risk. Highly active antiretroviral therapy (HAART), widely available since 1996, prolongs life, but immune function is not fully restored. We conducted this study to assess long-term cancer risk among persons with AIDS relative to the general population and the impact of HAART on cancer incidence. METHODS Records of 263 254 adults and adolescents with AIDS (1980-2004) from 15 US regions were matched to cancer registries to capture incident cancers during years 3 through 5 and 6 through 10 after AIDS onset. Standardized incidence ratios (SIRs) were used to assess risks relative to the general population. Rate ratios (RRs) were used to compare cancer incidence before and after 1996 to assess the impact of availability of HAART. RESULTS Risk was elevated for the 2 major AIDS-defining cancers: Kaposi sarcoma (SIRs, 5321 and 1347 in years 3-5 and 6-10, respectively) and non-Hodgkin lymphoma (SIRs, 32 and 15). Incidence of both malignancies declined in the HAART era (1996-2006). Risk was elevated for all non-AIDS-defining cancers combined (SIRs, 1.7 and 1.6 in years 3-5 and 6-10, respectively) and for the following specific non-AIDS-defining cancers: Hodgkin lymphoma and cancers of the oral cavity and/or pharynx, tongue, anus, liver, larynx, lung and/or bronchus, and penis. Anal cancer incidence increased between 1990-1995 and 1996-2006 (RR, 2.9; 95% confidence interval [CI], 2.1-4.0), as did that of Hodgkin lymphoma (RR, 2.0; 95% CI, 1.3-2.9). CONCLUSION Among people who survived for several years or more after an AIDS diagnosis, we observed high risks of AIDS-defining cancers and increasing incidence of anal cancer and Hodgkin lymphoma.

Multi-dimensional risk factor patterns associated with non-use of highly active antiretroviral therapy among human immunodeficiency virus-infected women. Womens Health Issues 2010; 20:335-42.

Abstract
OBJECTIVES Relationships between non-use of highly active antiretroviral therapy (HAART), race/ethnicity, violence, drug use, and other risk factors are investigated using qualitative profiles of five risk factors (unprotected sex, multiple male partners, heavy drinking, crack, cocaine or heroin use, and exposure to physical violence) and association of the profiles and race/ethnicity with non-use of HAART over time. METHODS A hidden Markov model was used to summarize risk factor profiles and changes in profiles over time in a longitudinal sample of HIV-infected women enrolled in the Women's Interagency HIV Study with follow-up from 2002 to 2005 (n = 802). RESULTS Four risk factor profiles corresponding to four distinct latent states were identified from the five risk factors. Trajectory analysis indicated that states characterized by high probabilities of all risk factors or by low probabilities of all risk factors were both relatively stable over time. Being in the highest risk state did not significantly elevate the odds of HAART non-use (odds ratio [OR], 1.05; 95% confidence interval [CI], 0.6-1.8). However, being in a latent state characterized by elevated probabilities of heavy drinking and exposure to physical violence, along with slight elevations in three other risk factors, significantly increased odds of HAART non-use (OR, 1.4; 95% CI, 1.1-1.9). CONCLUSION The research suggests that HAART use might be improved by interventions aimed at women who are heavy drinkers with recent exposure to physical violence and evidence of other risk factors. More research about the relationship between clustering and patterns of risk factors and use of HAART is needed.

Abstract
OBJECTIVE The influence of biological sex on human immunodeficiency virus (HIV) antiretroviral treatment outcome is not well described in HIV-hepatitis C (HCV) coinfection. METHODS We assessed patients' clinical outcomes of HIV-HCV coinfected patients initiating antiretroviral therapy attending the Ottawa Hospital Immunodeficiency Clinic from January 1996 to June 2008. RESULTS We assessed 144 males and 39 females. Although similar in most baseline characteristics, the CD4 count was higher in females (375 vs 290 cells/muL). Fewer females initiated ritonavir-boosted regimens. The median duration on therapy before interruption or change was longer in males (10 versus 4 months) (odds ratio [OR] 1.40 95% confidence interval: 0.95-2.04; P = 0.09). HIV RNA suppression was frequent (74%) and mean CD4 count achieved robust (over 400 cells/muL) at 6 months, irrespective of sex. The primary reasons for therapy interruption in females and males included: gastrointestinal intolerance (25% vs 19%; P = 0.42); poor adherence (22% vs 15%; P = 0.31); neuropsychiatric symptoms (19% vs 5%; P = 0.003); and lost to follow-up (3% vs 13%; P = 0.08). Seven males (5%) and no females discontinued therapy for liver-specific complications. Death rate was higher in females (23% vs 7%; P = 0.003). CONCLUSION There are subtle differences in the characteristics of female and male HIV-HCV coinfected patients that influence HIV treatment decisions. The reasons for treatment interruption and change differ by biological sex. This knowledge should be considered when starting HIV therapy and in efforts to improve treatment outcomes.

Abstract
AIMS Despite proven benefits of antiretroviral therapy (ART), many human immunodeficiency virus (HIV)-infected injection drug users (IDU) do not access treatment even in settings with free health care. We examined whether methadone maintenance therapy (MMT) increased initiation and adherence to ART among an IDU population with free health care. DESIGN We examined prospectively a cohort of opioid-using antiretroviral-naive HIV-infected IDU and investigated factors associated with initiation of antiretroviral therapy as well as subsequent adherence. Factors associated independently with time to first initiation of antiretroviral therapy were modelled using Cox proportional hazards regression. FINDINGS Between May 1996 and April 2008, 231 antiretroviral-naive HIV-infected opioid-using IDU were enrolled, among whom 152 (65.8%) initiated ART, for an incidence density of 30.5 [95% confidence interval (CI): 25.9-35.6] per 100 person-years. After adjustment for time-updated clinical characteristics and other potential confounders, use of MMT was associated independently with more rapid uptake of antiretroviral therapy [relative hazard = 1.62 (95% CI: 1.15-2.28); P = 0.006]. Those prescribed methadone also had higher rates of ART adherence after first antiretroviral initiation [odds ratio = 1.49 (95% CI: 1.07-2.08); P = 0.019]. CONCLUSION These results demonstrate that MMT contributes to more rapid initiation and subsequent adherence to ART among opioid-using HIV-infected IDU. Addressing international barriers to the use and availability of methadone may increase dramatically uptake of HIV treatment among this population.

Abstract
To benefit maximally from antiretroviral therapy, patients with HIV infection must enter care before their disease is advanced and adhere to care. We sought to determine if and where on this continuum of care racial/ethnic disparities were evident. Data from the Flexible Initial Retrovirus Suppressive Therapies (FIRST) trial, which evaluated three strategies for initial HIV therapy, were compared for White, African American, and Latino subjects. Outcomes included progression of disease and death, HIV viral suppression, and change in CD4(+) cell count. Multivariate Cox proportional hazard models adjusted for known predictors of survival. There were 1357 subjects, including 368 non-Latino white, 751 non-Latino African American, and 238 Latino subjects. At baseline, the two latter groups were more likely to have had AIDS and had lower CD4(+) cell counts than white subjects. In follow-up, African American subjects had lower self-reported adherence to therapy, lower CD4(+) cell count increases, and lower odds of viral suppression. African American and Latino subjects had unadjusted hazard ratios of progression of disease or death of 1.57 (1.17, 2.10; p = 0.0025) and 1.57 (1.09, 2.26; p = 0.02), respectively. Adjusting for baseline differences and differences in adherence, CD4(+) cell count change, and viral suppression accounted for the disparities in outcomes. Opportunities to reduce disparities in outcomes for African American and Latino patients exist along the continuum of HIV care. Efforts to promote access to HIV testing and care and to improve adherence have the potential to reduce racial/ethnic disparities in outcomes of patients with HIV infection.

Abstract
BACKGROUND Most persons with human immunodeficiency virus (HIV) infection in the United States present to care with advanced disease, and many patients discontinue therapy prematurely. We sought to evaluate sex and racial/ethnic disparities in life-years lost as a result of risk behavior, late presentation, and early discontinuation of HIV care, and we compared these survival losses for HIV-infected persons with losses attributable to high-risk behavior and HIV disease itself. METHODS With use of a state-transition model of HIV disease, we simulated cohorts of HIV-infected persons and compared them with uninfected individuals who had similar demographic characteristics. We estimated non-HIV-related mortality with use of risk-adjusted standardized mortality ratios, as well as years of life lost because of late presentation and early discontinuation of antiretroviral therapy (ART) for HIV infection. Data from the national HIV Research Network, stratified by sex and race/ethnicity, were used for estimating CD4+ cell counts at ART initiation. RESULTS For HIV-uninfected persons in the United States who have risk profiles similar to those of individuals with HIV infection, the projected life expectancy, starting at 33 years of age, was 34.58 years, compared with 42.91 years for the general US population. Those with HIV infection lost an additional 11.92 years of life if they received HIV care concordant with guidelines; late treatment initiation resulted in 2.60 additional years of life lost, whereas premature ART discontinuation led to 0.70 more years of life lost. Losses from late initiation and early discontinuation were greatest for Hispanic individuals (3.90 years). CONCLUSIONS The high-risk profile of HIV-infected persons, HIV infection itself, as well as late initiation and early discontinuation of care, all lead to substantial decreases in life expectancy. Survival disparities resulting from late initiation and early discontinuation of therapy are most pronounced for Hispanic HIV-infected men and women. Interventions focused on risk behaviors, as well as on earlier linkage to and better retention in care, will lead to improved survival for HIV-infected persons in the United States.

Abstract
OBJECTIVES We examined racial/ethnic disparities in highly active antiretroviral therapy (HAART) use and whether differences are moderated by substance use or insurance status, using data from the Women's Interagency HIV Study (WIHS). METHODS Logistic regression examined HAART use in a longitudinal cohort of women for whom HAART was clinically indicated in 2005 (N = 1354). RESULTS Approximately 3 of every 10 eligible women reported not taking HAART. African American and Hispanic women were less likely than were White women to use HAART. After we adjusted for potential confounders, the higher likelihood of not using HAART persisted for African American but not for Hispanic women. Uninsured and privately insured women, regardless of race/ethnicity, were less likely than were Medicaid enrollees to use HAART. Although alcohol use was related to HAART nonuse, illicit drug use was not. CONCLUSIONS These findings suggest that expanding and improving insurance coverage should increase access to antiretroviral therapy across racial/ethnic groups, but it is not likely to eliminate the disparity in use of HAART between African American and White women with HIV/AIDS.

Abstract
BACKGROUND State AIDS Drug Assistance Programs (ADAPs) provide antiretroviral medications to patients with no access to medications. Resource constraints limit the ability of many ADAPs to meet demand for services. OBJECTIVE To determine ADAP eligibility criteria that minimize morbidity and mortality and contain costs. METHODS We used Discrete Event Simulation to model the progression of HIV-infected patients and track the utilization of an ADAP. Outcomes included 5-year mortality and incidence of first opportunistic infection or death and time to starting antiretroviral therapy (ART). We compared expected outcomes for 2 policies: (1) first-come first-served (FCFS) eligibility for all with CD4 count <or=350/microL (current standard) and (2) CD4 count prioritized eligibility for those with CD4 counts below a defined threshold. RESULTS In the base case, prioritizing patients with CD4 counts <or=250/microL led to lower 5-year mortality than FCFS eligibility (2.77 vs. 3.27 deaths per 1,000 person-months) and to a lower incidence of first opportunistic infection or death (5.55 vs. 6.98 events per 1,000 person-months). CD4-based eligibility reduced the time to starting ART for patients with CD4 counts <or=200/microL. In sensitivity analyses, CD4-based eligibility consistently led to lower morbidity and mortality than FCFS eligibility. CONCLUSION When resources are limited, programs that provide ART can improve outcomes by prioritizing patients with low CD4 counts.

Black race as a predictor of poor health outcomes among a national cohort of HIV/AIDS patients admitted to US hospitals: a cohort study. BMC Infect Dis 2009; 9:127. [PMID: 19671170 PMCID: PMC2736968 DOI: 10.1186/1471-2334-9-127] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2009] [Accepted: 08/11/2009] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND In general, the Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) population has begun to experience the benefits of highly active antiretroviral therapy (HAART); unfortunately, these benefits have not extended equally to Blacks in the United States, possibly due to differences in patient comorbidities and demographics. These differences include rates of hepatitis B and C infection, substance use, and socioeconomic status. To investigate the impact of these factors, we compared hospital mortality and length of stay (LOS) between Blacks and Whites with HIV/AIDS while adjusting for differences in these key characteristics. METHODS The 1996-2006 National Hospital Discharge Surveys were used to identify HIV/AIDS patients admitted to US hospitals. Survey weights were incorporated to provide national estimates. Patients < 18 years of age, those who left against medical advice, those with an unknown discharge disposition and those with a LOS < 1 day were excluded. Patients were stratified into subgroups by race (Black or White). Two multivariable logistic regression models were constructed with race as the independent variable and outcomes (mortality and LOS > 10 days) as the dependent variables. Factors that were significantly different between Blacks and Whites at baseline via bivariable statistical tests were included as covariates. RESULTS In the general US population, there are approximately 5 times fewer Blacks than Whites. In the present study, 1.5 million HIV/AIDS hospital discharges were identified and Blacks were 6 times more likely to be hospitalized than Whites. Notably, Blacks had higher rates of substance use (30% vs. 24%; P < 0.001), opportunistic infections (27% vs. 26%; P < 0.001) and cocaine use (13% vs. 5%; P < 0.001). Conversely, fewer Blacks were co-infected with hepatitis C virus (8% vs. 12%; P < 0.001). Hepatitis B virus was relatively infrequent (3% for both groups). Crude mortality rates were similar for both cohorts (5%); however, a greater proportion of Blacks had a LOS > 10 days (21% vs. 19%; P < 0.001). Black race, in the presence of comorbidities, was correlated with a higher odds of LOS > 10 days (OR, 95% CI = 1.20 [1.10-1.30]), but was not significantly correlated with a higher odds of mortality (OR, 95% CI = 1.07 [0.93-1.25]). CONCLUSION Black race is a predictor of LOS > 10 days, but not mortality, among HIV/AIDS patients admitted to US hospitals. It is possible that racial disparities in hospital outcomes may be closing with time.

Abstract
BACKGROUND Homeless persons with HIV/AIDS have greater morbidity and mortality, more hospitalizations, less use of antiretroviral therapy, and worse medication adherence than HIV-infected persons who are stably housed. We examined the effect of homelessness on the mortality of persons with AIDS and measured the effect of supportive housing on AIDS survival. METHODS The San Francisco AIDS registry was used to identify homeless and housed persons who were diagnosed with AIDS between 1996 and 2006. The registry was computer-matched with a housing database of homeless persons who received housing after their AIDS diagnosis. The Kaplan-Meier product limit method was used to compare survival between persons who were homeless at AIDS diagnosis and those who were housed. Proportional hazards models were used to estimate the independent effects of homelessness and supportive housing on survival after AIDS diagnosis. RESULTS Of the 6,558 AIDS cases, 9.8% were homeless at diagnosis. Sixty-seven percent of the persons who were homeless survived five years compared with 81% of those who were housed (p < 0.0001). Homelessness increased the risk of death (adjusted relative hazard [RH] 1.20; 95% confidence limits [CL] 1.03, 1.41). Homeless persons with AIDS who obtained supportive housing had a lower risk of death than those who did not (adjusted RH 0.20; 95% CL 0.05, 0.81). CONCLUSION Supportive housing ameliorates the negative effect of homelessness on survival with AIDS.

Abstract
OBJECTIVES More than one quarter of HIV-infected people are undiagnosed and therefore unaware of their HIV-positive status. Blacks are disproportionately infected. Although perceived racism influences their attitudes toward HIV prevention, how racism influences their behaviors is unknown. We sought to determine whether perceiving everyday racism and racial segregation influence Black HIV testing behavior. METHODS This was a clinic-based, multilevel study in a North Carolina city. Eligibility was limited to Blacks (N = 373) seeking sexually transmitted disease diagnosis or screening. We collected survey data, block group characteristics, and lab-confirmed HIV testing behavior. We estimated associations using logistic regression with generalized estimating equations. RESULTS More than 90% of the sample perceived racism, which was associated with higher odds of HIV testing (odds ratio = 1.64; 95% confidence interval = 1.07, 2.52), after control for residential segregation, and other covariates. Neither patient satisfaction nor mechanisms for coping with stress explained the association. CONCLUSIONS Perceiving everyday racism is not inherently detrimental. Perceived racism may improve odds of early detection of HIV infection in this high-risk population. How segregation influences HIV testing behavior warrants further research.

Abstract
BACKGROUND Disparities in the use of antiretroviral therapy (ART) for HIV disease have been documented across race, gender, and substance use groups. OBJECTIVE The current analysis compares self-reported reasons for never taking or stopping ART among a diverse sample of men and women living with HIV. DESIGN Cross-sectional interview. PARTICIPANTS HIV + (N = 3,818) adults, 968 of whom reported discontinuing or never using ART. MEASUREMENTS Computerized self-administered and interviewer-administered self-reported demographic and treatment variables, including gender, race, ethnicity, CD4 count, detectable viral load, and reported reasons for not taking antiretroviral therapy. RESULTS Despite equivalent use of ART in the current sample, African-American respondents were 1.7 times more likely to report wanting to hide their HIV status and 1.7 times more likely to report a change in doctors/clinics as reasons for stopping ART (p = .049, and p = .042) and had odds 4.5 times those of non-African Americans of reporting waiting for viral marker counts to worsen (p = < .0001). There was a lower tendency (OR = 0.4) for women to endorse concerns of keeping their HIV status hidden as a reason for stopping ART compared to men (p = .003). Although those with an IDU history were less likely to be on ART, no differences in reasons for stopping or never initiating ART were found between those with and without an IDU history. CONCLUSIONS A desire to conceal HIV status as well as a change in doctors/clinics as reasons for discontinuing ART were considerably more common among African Americans, suggesting that perceived HIV/AIDS stigma is an obstacle to maintenance of treatment. Findings also indicate differences in reasons for stopping ART by gender and a perceived desire to wait for counts to worsen as a reason for not taking ART by African Americans, regardless of detectable viral load, CD4 count, age, education, employment, sexual orientation, and site.

Abstract
The effect of education on health has been increasing over the past several decades. We hypothesize that this increasing disparity is related to health-related technical progress: more-educated people are the first to take advantage of technological advances that improve health. We test this hypothesis using data on disease-specific mortality rates for 1980 and 1990, and cancer registry data for 1973-1993. We estimate education gradients in mortality using compulsory schooling as a measure of education. We then relate these gradients to two measures of health-related innovation: the number of active drug ingredients available to treat a disease, and the rate of change in mortality from that disease. We find that more-educated individuals have a greater survival advantage in those diseases for which there has been more health-related technological progress.

Abstract
As the New York City HIV=AIDS epidemic began generalizing beyond traditionally high-risk groups in the early 1990s, AIDS Service Organizations (ASO) sought to increase access to medical care and broaden service offerings to incorporate the needs of low-income women and their families. Strategies to achieve entry into and retention in medical care included the development of integrated care facilities, case management, and a myriad of supportive service offerings. This study examines a nonrandom sample of 60 HIV-positive women receiving case management and supportive services at New York City ASOs. Over 55% of the women interviewed reported high access to care, 43% reported the ability to access urgent care all of the time and 94% reported high satisfaction with obstetrics=gynecology (OB=GYN) care. This held true across race=ethnicity, income level, medical coverage, and service delivery model.Women who accessed services at integrated care facilities offering onsite medical care and case management=supportive services perceived lower access to medical specialists as compared to those who received services at nonintegrated sites. Data from this analysis indicate that supportive services increase access to and satisfaction with both HIV and non-HIV-related health care. Additionally, women who received services at a medical model agency were more likely to report accessing non-HIV care at a clinic compared to those receiving services at a nonmedical model agencies, these women were more likely to report receiving non-HIV care at a hospital.

Abstract
OBJECTIVE To determine if the incidence of endstage renal disease (ESRD) due to lupus nephritis has decreased from 1996 to 2004. METHODS Patients age 15 years or older with incident ESRD due to lupus nephritis in 1996-2004 and living in one of the 50 United States or the District of Columbia were identified using the US Renal Data System, a national population-based registry of all patients receiving renal replacement therapy for ESRD. Incidence rates were computed for each calendar year, using population estimates of the US census as denominators. RESULTS Over the 9-year study period, 9199 new cases of ESRD due to lupus nephritis were observed. Incidence rates, adjusted to the age, sex, and race composition of the US population in 2000, were 4.4 per million in 1996 and 4.9 per million in 2004. Compared to the pooled incidence rate in 1996-1998, the relative risk of ESRD due to lupus nephritis in 1999-2000 was 0.99 (95% CI 0.93-1.06), in 2001-2002 was 0.99 (95% CI 0.92-1.06), and in 2003-2004 was 0.96 (95% CI 0.89-1.02). Findings were similar in analyses stratified by sex, age group, race, and socioeconomic status. CONCLUSION There was no decrease in the incidence of ESRD due to lupus nephritis between 1996 and 2004. This may reflect the limits of effectiveness of current treatments, or limitations in access, use, or adherence to treatment.

Abstract
No adequate data exist on patterns of injection drug use (IDU) prevalence over time within racial/ethnic groups in U.S. geographic areas. The absence of such prevalence data limits our understanding of the causes and consequences of IDU and hampers planning efforts for IDU-related interventions. Here, we (1) describe a method of estimating IDU prevalence among non-Hispanic Black and non-Hispanic White adult residents of 95 large U.S. metropolitan statistical areas (MSAs) annually over an 11-year period (1992--2002); (2) validate the resulting prevalence estimates; and (3) document temporal trends in these prevalence estimates. IDU prevalence estimates for Black adults were calculated in several steps: we (1) created estimates of the proportion of injectors who were Black in each MSA and year by analyzing databases documenting injectors' encounters with the healthcare system; (2) multiplied the resulting proportions by previously calculated estimates of the total number of injectors in each MSA and year (Brady et al., 2008); (3) divided the result by the number of Black adults living in each MSA each year; and (4) validated the resulting estimates by correlating them cross-sectionally with theoretically related constructs (Black- and White-specific prevalences of drug-related mortality and of mortality from hepatitis C). We used parallel methods to estimate and validate White IDU prevalence. We analyzed trends in the resulting racial/ethnic-specific IDU prevalence estimates using measures of central tendency and hierarchical linear models (HLM). Black IDU prevalence declined from a median of 279 injectors per 10,000 adults in 1992 to 156 injectors per 10,000 adults in 2002. IDU prevalence for White adults remained relatively flat over time (median values ranged between 86 and 97 injectors per 10,000 adults). HLM analyses described similar trends and suggest that declines in Black IDU prevalence decelerated over time. Both sets of IDU estimates correlated cross-sectionally adequately with validators, suggesting that they have acceptable convergent validity (range for Black IDU prevalence validation: 0.27 < r < 0.61; range for White IDU prevalence: 0.38 < r < 0.80). These data give insight, for the first time, into IDU prevalence trends among Black adults and White adults in large U.S. MSAs. The decline seen here for Black adults may partially explain recent reductions in newly reported cases of IDU-related HIV evident in surveillance data on this population. Declining Black IDU prevalence may have been produced by (1) high AIDS-related mortality rates among Black injectors in the 1990s, rates lowered by the advent of HAART; (2) reduced IDU incidence among Black drug users; and/or (3) MSA-level social processes (e.g., diminishing residential segregation). The stability of IDU prevalence among White adults between 1992 and 2002 may be a function of lower AIDS-related mortality rates in this population; relative stability (and perhaps increases in some MSAs) in initiating IDU among White drug users; and social processes. Future research should investigate the extent to which these racial/ethnic-specific IDU prevalence trends (1) explain, and are explained by, recent trends in IDU-related health outcomes, and (2) are determined by MSA-level social processes.

Abstract
There is a need for a psychometrically sound measure of the stigma experienced by diverse persons living with HIV/AIDS (PLHA). The goal of this study was to develop and evaluate a multidimentional measure of internalized HIV stigma that captures stigma related to treatment and other aspects of the disease among sociodemographically diverse PLHA. We developed a 28-item measure of internalized HIV stigma composed of four scales based on previous qualitative work. Internal consistency reliability estimates in a sample of 202 PLHA was 0.93 for the overall measure, and exceeded 0.85 for three of the four stigma scales. Items discriminated well across scales, and correlations of the scales with shame, social support, and mental health supported construct validity. This measure should prove useful to investigators examining in the role of stigma in HIV treatment and health outcomes, and evaluating interventions designed to mitigate the impacts of stigma on PLHA.

Abstract
BACKGROUND In 1998, highly active antiretroviral therapy (HAART) was widespread, but the diffusion of these life-saving treatments was not uniform. As half of all AIDS patients in the USA have Medicaid coverage, this study of a multistate Medicaid claims dataset was undertaken to assess disparities in the rates of HAART. METHODS Data came from 1998 Medicaid claims files from five states with varying HIV prevalence. ICD-9 codes were used to identify people with a diagnosis of HIV/AIDS or AIDS-defining illness. Multivariate analyses assessed associations between age, gender, race and state of residence for antiretroviral regimens consistent with HAART, as defined by 1998 Centers for Disease Control and Prevention (CDC) guidelines. RESULTS Among 7202 Medicaid enrolees with a diagnosis of HIV/AIDS or AIDS, 62% received HAART and 25% received no antiretroviral therapy. Multivariate analyses showed that age, race, gender and state were all significant predictors of receiving HAART: white, non-Hispanic patients were most likely to receive HAART (68.3%), with lower rates in Hispanic and black, non-Hispanic segments of the population (59.3% and 57.5%, respectively, p<0.001). Women were less likely to receive HAART than men (51.8% vs 69.3%, p<0.001). CONCLUSION Despite similar insurance coverage and drug benefits, life-saving treatments for HIV/AIDS diffused at widely varying rates in different segments of the Medicaid population. Research is needed to determine the extent to which racial, gender, interstate and region disparities currently correspond to barriers to such care.

Abstract
BACKGROUND The choice of antiretroviral drugs has evolved over the last decade. Recognition of trends and determinants of changes may help to make predictions on prescription patterns. METHODS Longitudinal analyses were performed every 6 months from 1996 to 2006, of all HIV-infected individuals who attended at one HIV/AIDS referral centre located in Madrid, Spain. RESULTS A total of 2602 different individuals attending during the study period were examined over 23 consecutive time-points. The number and proportion of patients under antiretroviral therapy significantly increased in the period 1996-99, with a plateau since then around 1100 patients, which represented around two-thirds of the patients seen at each time-point after the year 2000. The proportion of patients under antiretroviral therapy having undetectable viraemia significantly increased from 34.5% in 1996 to 80% in 2006. The relative use of nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs) has risen in recent years, while prescription of non-nucleoside reverse transcriptase inhibitors has declined compared with the period 1999-2001, when it peaked. Among NRTIs, the use of zalcitabine, stavudine and didanosine has dramatically declined or vanished, while zidovudine, lamivudine, abacavir and tenofovir have gained relevance. Among PIs, indinavir and nelfinavir have almost disappeared, being replaced by ritonavir-boosted PIs, mainly atazanavir and lopinavir. After its first introduction in the year 1999, efavirenz has been generally preferred over nevirapine. CONCLUSIONS The choice of antiretroviral drugs has evolved during the last decade, with safety and convenience issues driving most changes in prescription patterns, while antiviral success has dramatically increased.

Abstract
Women who are HIV positive incur a higher risk of mortality than men who are HIV positive, a difference which is primarily based in the social context of poverty. Economic crises that lead to homelessness, unmet subsistence needs, and sex exchange often reorder priorities among women with HIV infection, de-emphasizing consistent medical care or the use of antiretroviral therapy. High rates of mental illness, drug use, and victimization further increase health and safety risks. HIV prevention messages highlighting education and behavior change insufficiently address the predicament of indigent women where constrained survival choices in the context of poverty may take precedence over safe behaviors. In this article, we highlight the risks of poor and unstably housed women to clarify the context in which risks occur. Suggestions for service provision are offered with the understanding that providers may have limited time and expertise to meet the entire array of needs for impoverished women.

Abstract
OBJECTIVES We examined whether the timing of initiation of antiretroviral therapy (ART) in routine clinical practice reflected treatment guidelines, which have evolved towards recommending starting therapy at lower CD4 cell counts. METHODS We analysed longitudinal data on 10,820 patients enrolled in the UK Collaborative HIV Cohort (UK CHIC) Study, which includes seven large clinical centres in south-east England. CD4 cell and viral load measurements performed in the period between 1 January 1997 and 31 December 2003 were classified according to whether ART was subsequently initiated or deferred, to estimate the probability of ART initiation by CD4 count and viral load over time. The effect of nonclinical factors (age, sex, ethnicity, and exposure category) was analysed by logistic regression. Kaplan-Meier analysis was used to estimate the proportion of patients who had initiated ART by a particular CD4 count among 'early' presenters (initial CD4 cell count >500 cells/microL). RESULTS There was a tendency to initiate ART at lower CD4 cell counts over time in the years 1997-2000, especially in the range 200-500 cells/microL, with little change thereafter. An estimated 34% of HIV-infected individuals having presented early initiated ART at a CD4 count <200 cells/microL. We also found an independent influence of viral load, which was particularly pronounced for CD4 <350 cells/microL. Use of injection drugs was the only nonclinical factor associated with initiation of ART at lower CD4 cell counts. CONCLUSIONS The initiation of ART in the clinics included in this analysis reflected evolving treatment guidelines. However, an unexpectedly high proportion of patients started ART at lower CD4 counts than recommended, which is only partly explained by late presentation.

Abstract
HIV-seropositive blacks, Hispanics, women of all ethnicities, and injection drug users (IDUs) have low rates of clinical trial participation. The opinions of research nurses and study coordinators as potential facilitators and barriers to access to clinical trials may contribute to this disparity. Study coordinators and research nurses from the adult AIDS Clinical Trials Group (ACTG) clinical trials units responded to an anonymous computer-based survey comprising multiple choice questions and clinical scenarios. Descriptive statistics were used to determine frequencies of responses. Recruitment rates of blacks, Hispanics, women and IDUs were mostly rated appropriate compared with the geographic region demographics. Most sites ranked white men as being the most interested in clinical trials. Sites rated their most effective interactions were with white men. Respondents felt they were less likely to enroll individuals who had missed previous clinical appointments or did not speak English. Perceptions that IDUs, Hispanics, blacks, and, to a lesser extent, women had less interest in clinical trials participation than white males may affect recruitment of the targeted populations. Interventions to improve interactions with targeted populations and to remove logistical and language barriers may improve the diversity of clinical trial participants.

Abstract
The eye is a common site for complications of human immunodeficiency virus (HIV) infection. Although cytomegalovirus retinitis remains the most prevalent of the blinding ocular disorders that can occur in individuals with the acquired immunodeficiency syndrome (AIDS), several important HIV-associated disorders may involve the anterior segment, ocular surface, and adnexae. Some of these entities, such as Kaposi sarcoma, were well described, but uncommon, before the HIV epidemic. Others, like microsporidial keratoconjunctivitis, have presentations that differ between affected individuals with HIV disease and those from the general population who are immunocompetent. The treatment of many of these diseases is challenging because of host immunodeficiency. Survival after the diagnosis of AIDS has increased among individuals with HIV disease because of more effective antiretroviral therapies and improved prophylaxis against, and treatment of, opportunistic infections. This longer survival may lead to an increased prevalence of anterior segment and external ocular disorders. In addition, the evaluation and management of disorders such as blepharitis and dry eye, which were previously overshadowed by more severe, blinding disorders, may demand increased attention, as the general health of this population improves. Not all individuals infected with HIV receive potent antiretroviral therapy, however, because of socioeconomic or other factors, and others will be intolerant of these drugs or experience drug failure. Ophthalmologists must, therefore, still be aware of the ocular findings that develop in the setting of severe immunosuppression. This article reviews the spectrum of HIV-associated anterior segment and external ocular disorders, with recommendations for their evaluation and management.

Abstract
BACKGROUND We examined the interaction of illicit drug use and depressive symptoms, and how they affect the subsequent likelihood of highly active antiretroviral therapy (HAART) use among women with HIV/AIDS. METHODS Subjects included 1710 HIV-positive women recruited from six sites in the U.S. including Brooklyn, Bronx, Chicago, Los Angeles, San Francisco/Bay Area, and Washington, DC. Cases of probable depression were identified using depressive symptom scores on the Center for Epidemiologic Studies Depression Scale. Crack, cocaine, heroin, and amphetamine use were self-reported at 6-month time intervals. We conducted multivariate random logistic regression analysis of data collected during 16 waves of semiannual interviews conducted from April 1996 through March 2004. RESULTS We found an interaction effect between illicit drug use and depression that acted to suppress subsequent HAART use, controlling for virologic and immunologic indicators, socio-demographic variables, time, and study site. CONCLUSIONS This is the first study to document the interactive effects of drug use and depressive symptoms on reduced likelihood of HAART use in a national cohort of women. Since evidence-based behavioral health and antiretroviral therapies for each of these three conditions are now available, comprehensive HIV treatment is an achievable public health goal.

Abstract
This paper examines factors associated with engaging socially marginalized HIV-positive persons in primary care using interview and chart review data from 984 clients presenting for services at 10 agencies participating in a multisite demonstration project. The sample was predominantly minority, and many reported drug and mental health problems as well as housing instability. At baseline, roughly half of the participants were engaged in HIV primary care; the other participants were either not at all engaged in HIV primary care or somewhat engaged in care. Those who were somewhat engaged in care were very similar to those who were not at all engaged in care, and significantly different than those who were fully engaged in care across a number of demographic, health status/utilization, and barriers to care items and fared equally poorly with regard to engagement in care at 12-month follow-up. In 12-month longitudinal analyses, 58% of those not engaged at baseline ( n = 517) became more fully engaged in care. In the final multivariate model that controlled for disease stage, decreases in drug use, structural barriers, and unmet needs were associated with engagement in care. Interventions that focus on decreasing structural barriers and unmet support services needs, addressing negative health beliefs and attending to drug use are promising public health strategies to engage marginalized HIV-positive persons in HIV primary care.

Abstract
We sought to examine whether diffusion of new HIV technologies differed by gender in the United States, the source of any such disparities, and whether disparities narrow over time as technologies become more established. In particular, we assess how rates of use of highly active antiretroviral therapy (HAART) varied between males and females during the late 1990s, when HAART was rapidly diffusing. We examined data from a prospective cohort study of a national probability sample of 1421 HIV-infected adults in medical care who were enrolled in the HIV Cost and Services Utilization Study (HCSUS) from January 1996 to December 1998. We found that HAART use substantially increased between 1996 and early 1998 for all groups. Women were less likely to receive HAART at all time points, although the diffusion of HAART between 1996 and 1998 reduced gender disparities. Gender disparities in 1998 were only partially explained by women's lower income and educational levels. We conclude that HAART therapy diffused more slowly to HIV-positive females than other groups. Policies that reduce the impact of income and education inequalities on health care may help to narrow gender disparities for new HIV technologies, but other factors may also disadvantage women.

Abstract
This study examined the effect of syringe exchange program setting on the injection practices, health status, and health service utilization patterns of injection drug users (IDUs) recruited from a public urban hospital. One hundred sixty-six participants were randomized to either community- or hospital-based syringe exchange services. Poisson regression models were used to compare service utilization between groups. In both conditions, risky drug use practices decreased, and physical health functioning improved over time. Hospital-based syringe exchange program (SEP) attendees had 83% more inpatient admissions (p < .0001) and 22% more ambulatory care visits (p < .0001) than those assigned to the community-based SEP condition. Syringe exchange services that are integrated into public hospital settings may serve as a valuable strategy to engage hard to reach IDU populations in behavioral interventions designed to reduce HIV risk transmission behaviors and increase access to, or engagement in, the use of secondary and tertiary preventive medical care.

Abstract
BACKGROUND Receipt of highly active antiretroviral therapy (HAART) differs by gender and racial/ethnic group and may reflect an effect of mood disorders. OBJECTIVE We examined the effects of dysthymia and major depression on HAART use by 6 groups defined by gender and race/ethnicity (white, black, Hispanic). MAIN OUTCOME MEASURE Self-reported HAART use in the past 6 months. DATA SOURCE Interview data from the HIV Cost and Services Utilization Study (HCSUS). Independent variables measured in or before the first half of 1997, and HAART use measured in the second half of 1997. ANALYSES Multivariate logistic regression of depression and dysthymia on HAART use by 6 patient groups. PARTICIPANTS One thousand nine hundred and eighty-two HIV-infected adults in HIV care in 1996 and with a CD4 count <500 in 1997. RESULTS Highly active antiretroviral therapy receipt was the highest for white men (68.6%) and the lowest for Hispanic women (52.7%) and black women (55.4%). Dysthymia was more prevalent in women (Hispanic, 46%; black, 27%; white, 31%) than men (Hispanic, 23%; black, 18%; white, 15%). The prevalence of major depression was greater in whites (women, 35%; men, 31%) than minorities (women, 26%; men, 21%). Compared with white men without dysthymia, the adjusted odds ratios (AORs) of HAART were significantly lower for black women (0.50 [95% confidence interval [95% CI] 0.29 to 0.87]) and Hispanic women (0.45 [95% CI 0.25, 0.79]). Among patients with depression and no dysthymia, minority women had HAART use (AOR=1.28 [95% CI 0.48 to 3.43]) similar to white men. LIMITATIONS Self-report data from the early era of HAART use; causation cannot be proven; mental health diagnoses may not meet full DSM IV criteria. CONCLUSIONS Dysthymia is highly prevalent in minority women and associated with a 50% reduction in the odds of receiving HAART. This underrecognized condition may contribute more than depression to the "gender disparity" in HAART use.
