Abstract
With over 1 million people living with HIV, the US faces national challenges in HIV care delivery due to an inadequate HIV specialist workforce and the increasing role of non-communicable chronic diseases in driving morbidity and mortality in HIV-infected patients. Alternative HIV care delivery models, which include substantial roles for advanced practitioners and/or coordination between specialty and primary care settings in managing HIV-infected patients, may address these needs. We aimed to systematically review the evidence on patient-level HIV-specific and primary care health outcomes for HIV-infected adults receiving outpatient care across HIV care delivery models. We identified randomized trials and observational studies from bibliographic and other databases through March 2016. Eligible studies met pre-specified eligibility criteria including on care delivery models and patient-level health outcomes. We considered all available evidence, including non-experimental studies, and evaluated studies for risk of bias. We identified 3605 studies, of which 13 met eligibility criteria. Of the 13 eligible studies, the majority evaluated specialty-based care (9 studies). Across all studies and care delivery models, eligible studies primarily reported mortality and antiretroviral use, with specialty-based care associated with mortality reductions at the clinician and practice levels and with increased antiretroviral initiation or use at the clinician level but not the practice level. Limited and heterogeneous outcomes were reported for other patient-level HIV-specific outcomes (e.g., viral suppression) as well as for primary care health outcomes across all care delivery models. No studies addressed chronic care outcomes related to aging. Limited evidence was available across geographic settings and key populations. As re-design of care delivery in the US continues to evolve, better understanding of patient-level HIV-related and primary care health outcomes, especially across different staffing models and among different patient populations and geographic locations, is urgently needed to improve HIV disease management.

Abstract
United States HIV guidelines delineate preferred antiretroviral treatment (ART) and discourage use of sub-potent, toxic, or adversely interacting combinations. It is unclear how often patients receive guideline concordant ART and what factors are correlated with receiving guideline-inconsistent ART. The objective of this study was to assess ART reported by participants of the Women's Interagency HIV Study (WIHS) and the Multicenter AIDS Cohort Study (MACS) to determine whether gender is associated with receipt of guideline-inconsistent ART. ART reported by WIHS and MACS participants from 1 January 2001, to 31 December 2007, was assessed for concordance with HIV guidelines. Logistic regression with generalized estimating equations estimated the crude and adjusted odds ratios and 95% confidence intervals associated with guideline-inconsistent regimens. Of 2937 participants, 463 subjects (WIHS n = 263; MACS n = 200) reported guideline-inconsistent ART during the study period. Age > 50 years (aOR = 2.22, 95% CI 1.14, 4.33) and HIV-1 RNA (aOR = 1.17, 95% CI 1.08, 1.25) but not participant gender (aOR = 1.21, 95% CI 0.88, 1.65) were associated with guideline-inconsistent ART. The prevalence of guideline-inconsistent ART peaked in 2004; however, there was not a statistically significant increase or decrease over time. Guideline-inconsistent ART was not related to gender, but was often used by older patients and patients with higher viral loads. Monitoring ART quality based on concordance with expert guidelines could improve treatment outcomes in a substantial number of patients.

Abstract
Women currently account for 27% of new human immunodeficiency virus (HIV) infections in the United States, the majority of which are acquired through heterosexual transmission. In the United States, black and Latino persons are disproportionately affected by the HIV epidemic, a disparity that is most dramatically present among HIV-infected women. Many of these women face significant discrimination as a result of race or ethnicity and sex, and they suffer disproportionately from poverty, low health literacy, and lack of access to high-quality HIV care. As a consequence, despite the availability of highly active antiretroviral therapy (HAART), women with HIV often have delayed entry into care and experience poor outcomes. This article reviews risk factors for HIV infection in women, barriers to engagement in care, and strategies to improve linkage to HIV-related medical and social care.

Abstract
At least half of all HIV infections occur in women. Most women are of childbearing potential; therefore, issues encompassing reproduction and mother-to-child transmission are critical in the management of this population. The efficacy of antiretroviral therapy (ART) is similar in men and women, although rates of adverse events or toxicity may be higher in women, which, in turn, may be related to higher antiretroviral drug levels documented in pharmacokinetic studies. A substantial proportion of women may not derive the benefit of highly active ART because nonsuppressive regimens are commonly used, especially in resource-limited settings, to decrease mother-to-child transmission. The likely emergence of resistant virus can have long-term sequelae for the mother, child, and other exposed individuals. Additional studies are needed of sex/gender-related issues including antiretroviral toxicities, pharmacokinetic profiles of approved and novel agents, ART strategies during pregnancy to minimize HIV resistance, and determination of optimal antiretroviral regimens for women.

Abstract
OBJECTIVE To describe gender-based differences in disease progression, treatment, and outcome among patients receiving highly active antiretroviral therapy (HAART) in South India. METHODS Therapy-naïve patients initiating HAART between February 1996 and June 2006 at a tertiary HIV referral center in Chennai, South India, were analyzed using the YRG CARE HIV Observational Database. Patients with 1 year of follow-up after initiating HAART were examined to investigate immunological and clinical outcomes, including the development of adverse events to therapy and opportunistic infections. RESULTS All previously therapy-naïve patients who initiated HAART with at least 1 year of follow-up (n = 1972) were analyzed. At enrollment into care, women had higher CD4 counts, lower hemoglobin, and higher body mass index (BMI) than their male counterparts (p < 0.05). At the time of initiating therapy, women had higher CD4 counts and lower hemoglobin (p < 0.05); women continued to have higher CD4 counts at 12 months (p < 0.05). After 1 year following HAART initiation, significantly more men developed tuberculosis and Pneumocystis jiroveci pneumonia (p < 0.05), more women experienced lactic acidosis and nausea, and more men developed immune reconstitution syndrome (p < 0.05). CONCLUSIONS Significant physiological, immunological, and clinical differences exist between men and women initiating HAART in a resource-limited setting in South India. Future studies should examine whether clinical management strategies should be different for men and women in resource-limited settings.

Abstract
Globally, injection drug use continues to account for a substantial proportion of HIV infections. There have not, however, been any evidence-based reviews of the barriers and facilitators of HIV treatment among injection drug users. For this review, published studies were extracted from nine academic databases, with no language or date specified in the search criteria. Existing evidence demonstrates that, although injection drug users often have worse outcomes from HIV treatment than non-injection drug users, major antiretroviral-associated survival gains still have been observed among this population. Inferior outcomes are explained by a range of barriers to antiretroviral access and adherence, which often stem from the negative influences of illicit drug policies, as well as issues within medical systems, including lack of physician education about substance abuse. Evidence demonstrates that several under-utilized interventions and novel antiretroviral delivery modalities have helped to greatly address these barriers in several settings, and there is sufficient evidence to support immediate scale-up of these programmes. These interventions include coupling antiretroviral therapy with opioid substitution therapies as well as directly administered antiretroviral therapy programmes. Of particular interest for future evaluation is the coupling of HIV treatment programmes within comprehensive services, which also provide low-threshold (harm reduction) HIV prevention programmes. Scale-up of evidence-based HIV treatment and prevention to injection drug users, however, will require increasing political will among both national policy-makers and international public health agencies.

Abstract
This study examines the effects of treated and untreated depressive symptoms on the likelihood of utilization of highly active antiretroviral therapy (HAART) among a multi-site cohort of HIV-infected women who screened positive for probable depression. Data were collected biannually from 1996 through 2001 in a prospective cohort study. Random-effects regression analysis was used to estimate the longitudinal effects of mental health treatment on the probability of HAART utilization, controlling for clinical indicators (CD4 count, viral load), demographic features (race/ethnicity, income), and behavioural factors (recent crack, cocaine, or heroin use). Use of antidepressants plus mental health therapy, or use of mental health therapy alone significantly increased the probability of HAART utilization, compared to receiving no depression treatment. Use of antidepressants alone did not differ significantly from receiving no depression treatment. African American women and those who used crack, cocaine, or heroin also were less likely to use HAART. These findings suggest that efforts to enhance depressed women's access to psychopharmacologic treatment and therapy may increase their use of the most effective HIV therapies.

Abstract
The present analysis was designed to determine whether race/ethnicity was independently associated with mother-to-child HIV-1 transmission risk in subjects enrolled in a trial of 2-dose intra-partum nevirapine in combination with standard antiretroviral therapy and to determine what factors, including race/ethnicity, predicted maternal viral suppression at the time of delivery. Women enrolled in Pediatric AIDS Clinical Trials Group (PACTG) 316 from sites in the United States and Puerto Rico were included. Distribution of selected maternal disease and treatment characteristics was assessed by race/ethnicity category. Logistic regression models were fit to evaluate possible association of factors with HIV transmission and with viral load at delivery. Variables associated with the outcome at P < 0.05 level were retained in the final models. Of 1052 women randomized at PACTG sites, 891 were included in the present analysis: 572 (64%) were black; 206 (23%) were Hispanic; and 113 (13%) were white. All women who had infected infants were black or Hispanic (11/572 and 3/206, respectively), whereas none of the women identified as white had an infected infant (0/113). This difference was not statistically significant (P = 0.54). White women had higher entry CD4 cell counts and lower HIV-1 RNA at delivery than women of other races/ethnicities. Black and Hispanic women were more likely than white women to start therapy during their current pregnancy but did not initiate prenatal care later. In bivariate models that included antiretroviral type and variables that had values of P < or = 0.25 in univariate analysis, time of antiretroviral initiation, time of prenatal care initiation, and race/ethnicity each retained significance in predicting viral suppression at delivery. Race/ethnicity remained predictive of viral suppression at delivery in a multivariate model incorporating all of these variables (P = 0.01). Higher HIV-1 RNA and lower CD4 cell counts in women identified as black or Hispanic have significant implications for the health of these women and their newborns. Race/ethnicity is significant in predicting viral suppression at the time of delivery.

Abstract
We aimed to identify factors associated with a medical provider's resistance to prescribing HAART to medically-eligible HIV-infected illicit drug users. In four US cities, a mailed, self-administered survey queried 420 HIV care providers about patients' characteristics and barriers to care. Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated using logistic regression. Providers identified as resistant to prescribing HAART to medically-eligible HIV-infected illicit drug users were more likely to be non-physicians (AOR=1.89, 95% CI: 1.04-3.46), to work in populations with a high prevalence of both mental illness (AOR=2.42; 95% CI: 1.11-5.26) and injection drug use (AOR=1.82 95% CI: 1.02-3.25) and were deterred from prescribing HAART by patients' limited ability to keep appointments, (AOR=3.19; 95% CI: 1.39-7.37), alcoholism (AOR=1.92; 95% CI: 1.04-3.55) and homelessness (AOR=1.81; 95% CI: 1.07-3.06). Providers working in populations with a high injection drug use prevalence commonly reported higher prevalence of non-injection drug use, alcohol problems and mental illness, and higher antiretroviral therapy refusal rates within their patient populations. Our findings underscore the challenges to providers who treat HIV-infected drug users and suggest that their care and treatment would benefit from on-site drug treatment, mental health and social services.

Abstract
OBJECTIVES We investigated the prevalence and characteristics of HIV-positive women who do not report highly active antiretroviral therapy (HAART) use. METHODS We analyzed HAART use among 1165 HIV-positive participants in the Women's Interagency HIV Study. RESULTS Between October 1, 2000, and March 31, 2001, 254 women with clinical indications for HAART reported not using it, 635 reported HAART use, and 276 had no clinical indications. In multivariate analysis, using crack/cocaine/heroin and a history of abuse decreased the likelihood of using HAART, whereas being White increased it. CONCLUSIONS One of 4 women for whom HAART was indicated reported not using HAART. Childhood sexual abuse prevention, more intensive abuse treatment, and continuing drug treatment may enhance HIV disease treatment of women.

Abstract
Cross-sectional studies to date that examine psychosocial correlates of antiretroviral adherence have insufficiently addressed the challenges of long-term adherence. This longitudinal study examined mental health, substance abuse, and psychosocial predictors of long-term adherence to antiretroviral medications and medical appointments among HIV-seropositive mothers recruited from an infectious disease clinic of a large urban medical center. Individual interviews were conducted at baseline and two follow-up points, 8 to 18 months after enrollment. Based on a model of health behavior, we examined psychiatric and psychosocial predictors of adherence to antiretroviral medications and medical appointments over time. Presence of a psychiatric disorder, negative stressful life events, more household members, and parenting stress were significantly associated with both missed pills and missed medical appointments at follow-up. Baseline substance abuse was associated with missed pills at follow-up and lack of disclosure to family members at baseline was associated with missed medical appointments at follow-up. These findings suggest that interventions that integrate mental health, substance abuse and medical care may be important to improving the medical adherence and health of HIV-seropositive women, particularly in multistressed populations with substantial caregiving and other life demands.
