RESUMO

Consistent care is crucial for the health maintenance of people living with human immunodeficiency virus (HIV) (PWH). The coronavirus 2019 (COVID-19) epidemic disrupted patient care in New York City (NYC), yet few studies investigated the association between COVID-19 and viral load suppression in PWH in NYC. This study aims to assess how the COVID-19 pandemic impacted HIV viral load and CD4 + T-cell counts in PWH. Medical records of 1130 adult HIV patients who visited the Special Treatment and Research Health Center in Brooklyn, NY, between January 2019 and May 2023 were compared across three timeframes (pre-pandemic, January 1, 2019 to December 31, 2019; first pandemic phase, March 19, 2020 to December 31, 2020; and second pandemic phase, January 1, 2021 to May 11, 2023). Demographic and clinical variables (e.g. viral load and CD4 + T cell count) were assessed. About 40% of patients did not have routine laboratory monitoring during the first pandemic phase compared with pre-pandemic. The mean HIV viral load was higher during the second pandemic phase compared with pre-pandemic (p = 0.009). The percentages of patients with undetectable HIV viral load and numbers (mm3) of CD4 + T-cells were similar for all time periods. These findings indicate that the COVID-19 pandemic may have exacerbated challenges for individuals who already had barriers to medication adherence or access. However, most individuals remained consistently on their antiretrovirals throughout the pandemic. Further studies are warranted to determine how to mitigate the impact of future pandemics for the health of PWH.

RESUMO

In 2019, the National Institutes of Health combined the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS) into the MACS/WIHS Combined Cohort Study (MWCCS). In this paper, participants who made a study visit during October 2018-September 2019 (targeted for MWCCS enrollment) are described by human immunodeficiency virus (HIV) serostatus and compared with people living with HIV (PLWH) in the United States. Participants include 2,115 women and 1,901 men with a median age of 56 years (interquartile range, 48-63); 62% are PLWH. Study sites encompass the South (18%), the Mid-Atlantic/Northeast (45%), the West Coast (22%), and the Midwest (15%). Participant race/ethnicity approximates that of PLWH throughout the United States. Longitudinal data and specimens collected for 35 years (men) and 25 years (women) were combined. Differences in data collection and coding were reviewed, and key risk factor and comorbidity data were harmonized. For example, recent use of alcohol (62%) and tobacco (28%) are common, as are dyslipidemia (64%), hypertension (56%), obesity (42%), mildly or severely impaired daily activities (31%), depressive symptoms (28%), and diabetes (22%). The MWCCS repository includes serum, plasma, peripheral blood mononuclear cells, cell pellets, urine, cervicovaginal lavage samples, oral samples, B-cell lines, stool, and semen specimens. Demographic differences between the MACS and WIHS can confound analyses by sex. The merged MWCCS is both an ongoing observational cohort study and a valuable resource for harmonized longitudinal data and specimens for HIV-related research.

RESUMO

BACKGROUND: It is unclear whether human immunodeficiency virus (HIV) infection results in permanent loss of T-cell memory or if it affects preexisting antibodies to childhood vaccinations or infections. METHODS: We conducted a matched cohort study involving 50 pairs of HIV-infected and HIV-uninfected women. Total memory T-cell responses were measured after anti-CD3 or vaccinia virus (VV) stimulation to measure T cells elicited after childhood smallpox vaccination. VV-specific antibodies were measured by means of enzyme-linked immunosorbent assay (ELISA). RESULTS: There was no difference between HIV-infected and HIV-uninfected study participants in terms of CD4+ T-cell responses after anti-CD3 stimulation (P = .19) although HIV-infected participants had significantly higher CD8+ T-cell responses (P = .03). In contrast, there was a significant loss in VV-specific CD4+ T-cell memory among HIV-infected participants (P = .04) whereas antiviral CD8+ T-cell memory remained intact (P > .99). VV-specific antibodies were maintained indefinitely among HIV-uninfected participants (half-life, infinity; 95% confidence interval, 309 years to infinity) but declined rapidly among HIV-infected participants (half-life; 39 years; 24-108 years; P = .001). CONCLUSIONS: Despite antiretroviral therapy-associated improvement in CD4+ T-cell counts (nadir, <200/µL; >350/µL after antiretroviral therapy), antigen-specific CD4+ T-cell memory to vaccinations or infections that occurred before HIV infection did not recover after immune reconstitution, and a previously unrealized decline in preexisting antibody responses was observed.

RESUMO

There is limited research examining the sexual health and well-being of older women living with HIV (OWLH). Most studies focus on sexual dysfunction, leaving aside the richer context of sexuality and sexual health, including the effect of age-related psychosocial and interpersonal changes on sexual health behaviors. Guided by the integrative biopsychosocial model and the sexual health model, this study explored the importance of sex and sexuality among OWLH to identify their sexual health and HIV prevention needs for program planning. A purposive sample (n = 50) of OWLH was selected from a parent study (n = 2052). We conducted 8 focus groups and 41 in-depth interviews with 50 African American and Latina OWLH aged 50-69 years old in three U.S. cities. The triangulation approach was used to synthesize the data. Six salient themes emerged: sexual pleasure changes due to age, sexual freedom as women age, the role of relationships in sexual pleasure, changes in sexual ability and sexual health needs, sexual risk behaviors, and ageist assumptions about older women's sexuality. We found that sexual pleasure and the need for intimacy continue to be important for OWLH, but that changing sexual abilities and sexual health needs, such as the reduction of sexual desire, as well as increased painful intercourse due to menopause-associated vaginal drying, were persistent barriers to sexual fulfillment and satisfaction. Particular interpersonal dynamics, including low perceptions of the risk of HIV transmission as related to gender, viral suppression, and habitual condomless sex with long-term partners without HIV transmission have resulted in abandoning safer sex practices with serodiscordant partners. These findings suggest that HIV prevention for OWLH should focus on how sexual function and satisfaction intersect with sexual risk. HIV prevention for OWLH should promote ways to maintain satisfying and safe sex lives among aging women.

RESUMO

Suboptimal adherence to antiretroviral (ARV) therapy among HIV-infected individuals is associated with increased risk of progression to AIDS and the development of HIV resistance to ARV medications. To examine whether the luteal phase of the menstrual cycle is independently associated with suboptimal adherence to single tablet regimen (STR) ARV medication, data were analyzed from a multicenter cohort study of HIV-infected women who reported regular menstrual cycles and were taking an STR. In a cross-sectional analysis, suboptimal adherence to an STR among women in their follicular phase was compared with suboptimal adherence among women in their luteal phase. In two-way crossover analyses, whereby the same woman was assessed for STR medication adherence in both her follicular and luteal phases, the estimated exact conditional odds of non-adherence to an STR was measured. In adjusted logistic regression analysis of the cross-sectional data (N=327), women with ≤12 years of education were more than three times more likely to have suboptimal adherence (OR=3.6, p=.04) compared to those with >12 years of education. Additionally, women with Center for Epidemiological Studies Depression Scale (CES-D) scores ≥23 were 2.5-times more likely to have suboptimal adherence (OR=2.6, p=.02) compared to those with CES-D scores <23. In conditional logistic regression analyses of the crossover data (N=184), having childcare responsibilities was associated with greater odds of ≤95% adherence. Menstrual cycle phase was not associated with STR adherence in either the cross-sectional or crossover analyses. The lack of association between phase of the menstrual cycle and adherence to an STR in HIV-infected women means attention can be given to other more important risk factors for suboptimal adherence, such as depression, level of education, and childcare responsibilities.

RESUMO

We assessed changes in self-reported sexual activity (SA) over 13 years among HIV-infected and uninfected women. The impact of aging and menopause on SA and unprotected anal or vaginal intercourse (UAVI) was examined among women in the Women's Interagency HIV Study (WIHS), stratifying by HIV status and detectable viral load among HIV-infected women. Generalized mixed linear models were fitted for each outcome, adjusted for relevant covariates. HIV-uninfected women evidenced higher levels of SA and UAVI than HIV-infected. The odds of SA declined by 62-64 % per decade of age. The odds of SA in a 6-month interval for women aged 40-57 declined by 18-22 % post-menopause (controlling for age). Among HIV+/detectable women only, the odds of any UAVI decreased by 17 % per decade of age; the odds of UAVI were unchanged pre-menopause, and then decreased by 28 % post-menopause. Elucidating the factors accounting for ongoing unprotected sex among older women should inform interventions.

RESUMO

BACKGROUND: The aim of the study was to determine whether enhanced personal contact with human immunodeficiency virus (HIV)-infected patients across time improves retention in care compared with existing standard of care (SOC) practices, and whether brief skills training improves retention beyond enhanced contact. METHODS: The study, conducted at 6 HIV clinics in the United States, included 1838 patients with a recent history of inconsistent clinic attendance, and new patients. Each clinic randomized participants to 1 of 3 arms and continued to provide SOC practices to all enrollees: enhanced contact with interventionist (EC) (brief face-to-face meeting upon returning for care visit, interim visit call, appointment reminder calls, missed visit call); EC + skills (organization, problem solving, and communication skills); or SOC only. The intervention was delivered by project staff for 12 months following randomization. The outcomes during that 12-month period were (1) percentage of participants attending at least 1 primary care visit in 3 consecutive 4-month intervals (visit constancy), and (2) proportion of kept/scheduled primary care visits (visit adherence). RESULTS: Log-binomial risk ratios comparing intervention arms against the SOC arm demonstrated better outcomes in both the EC and EC + skills arms (visit constancy: risk ratio [RR], 1.22 [95% confidence interval {CI}, 1.09-1.36] and 1.22 [95% CI, 1.09-1.36], respectively; visit adherence: RR, 1.08 [95% CI, 1.05-1.11] and 1.06 [95% CI, 1.02-1.09], respectively; all Ps < .01). Intervention effects were observed in numerous patient subgroups, although they were lower in patients reporting unmet needs or illicit drug use. CONCLUSIONS: Enhanced contact with patients improved retention in HIV primary care compared with existing SOC practices. A brief patient skill-building component did not improve retention further. Additional intervention elements may be needed for patients reporting illicit drug use or who have unmet needs. CLINICAL TRIALS REGISTRATION: CDCHRSA9272007.

RESUMO

BACKGROUND: Several lung diseases are increasingly recognized as comorbidities with HIV; however, few data exist related to the spectrum of respiratory symptoms, diagnostic testing, and diagnoses in the current HIV era. The objective of the study is to determine the impact of HIV on prevalence and incidence of respiratory disease in the current era of effective antiretroviral treatment. METHODS: A pulmonary-specific questionnaire was administered yearly for three years to participants in the Multicenter AIDS Cohort Study (MACS) and Women's Interagency HIV Study (WIHS). Adjusted prevalence ratios for respiratory symptoms, testing, or diagnoses and adjusted incidence rate ratios for diagnoses in HIV-infected compared to HIV-uninfected participants were determined. Risk factors for outcomes in HIV-infected individuals were modeled. RESULTS: Baseline pulmonary questionnaires were completed by 907 HIV-infected and 989 HIV-uninfected participants in the MACS cohort and by 1405 HIV-infected and 571 HIV-uninfected participants in the WIHS cohort. In MACS, dyspnea, cough, wheezing, sleep apnea, and incident chronic obstructive pulmonary disease (COPD) were more common in HIV-infected participants. In WIHS, wheezing and sleep apnea were more common in HIV-infected participants. Smoking (MACS and WIHS) and greater body mass index (WIHS) were associated with more respiratory symptoms and diagnoses. While sputum studies, bronchoscopies, and chest computed tomography scans were more likely to be performed in HIV-infected participants, pulmonary function tests were no more common in HIV-infected individuals. Respiratory symptoms in HIV-infected individuals were associated with history of pneumonia, cardiovascular disease, or use of HAART. A diagnosis of asthma or COPD was associated with previous pneumonia. CONCLUSIONS: In these two cohorts, HIV is an independent risk factor for several respiratory symptoms and pulmonary diseases including COPD and sleep apnea. Despite a higher prevalence of chronic respiratory symptoms, testing for non-infectious respiratory diseases may be underutilized in the HIV-infected population.

RESUMO

Background and objective: Observations of overweight and obesity in association with neuropsychological performance (NP) vary over the adult life course depending on baseline levels, biological sex, age, race, temporality of measurements, and other factors. Therefore, similar published analyses across cohorts are inconsistent. In our sample of women living with HIV (WLWH) and women without HIV (WWOH), we conducted comparable analyses as those published in men with and without HIV. We examined cross-sectional and longitudinal associations between body mass index (BMI) and waist circumference (WC) and NP. Methods: Four hundred thirty two 432 virologically-suppressed WLWH and 367 WWOH, ≥40 years in the Women's Interagency HIV Study (WIHS) with anthropometry and NP assessments every two years from 2009-2019 were included in the study. Demographically-adjusted T-scores were calculated for six NP domains: learning, memory, executive function, processing speed, attention and working memory, and motor function. Multivariable linear regression models stratified by HIV status were used to examine cross-sectional associations of BMI and WC by NP domain; repeated measures analyses assessed baseline BMI and WC in association with longitudinal change in NP. Covariates included sociodemographic, behavioral, and HIV-related characteristics. Results: At baseline among all women, the median age was 45 years, 65% were Non-Latinx Black women, and 45% were obese women. Obese WLWH (BMI≥30.0 kg/m2) had poorer executive function (ß=-2.27, 95%CI [-4.46, -0.07]) versus WLWH with healthy BMI (18.5-24.9 kg/m2). Longitudinally over ~8 years, obese versus overweight WWOH improved on memory (ß=2.19, 95%CI [0.13, 4.26]), however overweight versus healthy WWOH experienced declining memory (ß= -2.67, 95%CI [-5.40, -0.07]). Increasing WC was associated with declining executive, processing speed, and motor function (p's<0.05); an at-risk WC was associated with improved memory (ß=1.81, 95%CI [0.19, 3.44]) among WWOH. Among WLWH, increasing BMI was associated with improved learning (ß=0.07, 95%CI [0.00, 0.15]. Conclusion: Our cross-sectional and longitudinal analyses evaluating the associations of BMI and WC and NP were mixed compared to previous reports. This illustrates the importance of sociodemographic characteristics, baseline levels of exposures and outcomes, HIV status, temporality of measurements, and other factors when evaluating aging HIV epidemiology study results.

RESUMO

BACKGROUND: Retention in care for human immunodeficiency virus (HIV)-infected patients is a National HIV/AIDS Strategy priority. We hypothesized that retention could be improved with coordinated messages to encourage patients' clinic attendance. We report here the results of the first phase of the Centers for Disease Control and Prevention/Health Resources and Services Administration Retention in Care project. METHODS: Six HIV-specialty clinics participated in a cross-sectionally sampled pretest-posttest evaluation of brochures, posters, and messages that conveyed the importance of regular clinic attendance. 10,018 patients in 2008-2009 (preintervention period) and 11,039 patients in 2009-2010 (intervention period) were followed up for clinic attendance. Outcome variables were the percentage of patients who kept 2 consecutive primary care visits and the mean proportion of all primary care visits kept. Stratification variables were: new, reengaging, and active patients, HIV RNA viral load, CD4 cell count, age, sex, race or ethnicity, risk group, number of scheduled visits, and clinic site. Data were analyzed by multivariable log-binomial and linear models using generalized estimation equation methods. RESULTS: Clinic attendance for primary care was significantly higher in the intervention versus preintervention year. Overall relative improvement was 7.0% for keeping 2 consecutive visits and 3.0% for the mean proportion of all visits kept (P < .0001). Larger relative improvement for both outcomes was observed for new or reengaging patients, young patients and patients with elevated viral loads. Improved attendance among the new or reengaging patients was consistent across the 6 clinics, and less consistent across clinics for active patients. CONCLUSION: Targeted messages on staying in care, which were delivered at minimal effort and cost, improved clinic attendance, especially for new or reengaging patients, young patients, and those with elevated viral loads.

RESUMO

Previous studies of the association of the C17T polymorphism of the mu opiate receptor gene with substance dependence compared cases with substance dependence to controls and usually found no significant association. However, the studies were limited by small sample size-no study had more than 12 subjects with the TT genotype, a genotype that is rare in white and Asian subjects. Moreover, drug use is not dichotomous but follows a spectrum from non-use to modest, intermittent use, to use several times daily. We asked whether the Kreek-McHugh-Schluger-Kellogg (KMSK) scales for alcohol, cocaine, opiates and tobacco that quantify substance use during the time of a subject's maximal use might be more sensitive measures than dichotomous outcomes. We administered the KMSK scales and completed C17T genotyping on 1009 human immunodeficiency virus (HIV)-infected and 469 HIV-uninfected women in The Women's Interagency HIV Study, an ongoing study of HIV in women. Forty-two of the 697 African American, 1 of the 182 Hispanic and none of the 161 white women had the TT genotype. KMSK cocaine, alcohol and tobacco scores were significantly higher in the African American women with the TT genotype (P = 0.008, 0.0001, and 0.006, respectively), but opiate scores were not. Ordinal regression models controlling for HIV serostatus, age, education, and income had odds ratios for the TT genotype for predicting alcohol, tobacco, cocaine and opiates scores of 2.1 (P = 0.02), 2.4 (P = 0.0004), 2.0 (P = 0.03) and 1.9 (P = 0.07). We conclude that the TT genotype of OPRM1 may increase the risk of substance use and abuse.

RESUMO

CONTEXT: It is not yet understood whether people living with HIV infection have an increased risk of Alzheimers Disease and Related Dementias due to enhanced survivorship with highly effective antiretroviral therapies and/or increasing adiposity with aging. OBJECTIVE: This work aimed to determine whether body mass index (BMI) and leptin were longitudinally associated over 10 years with neuropsychological performance (NP) among middle-aged women with HIV (WWH) vs without HIV. METHODS: Women's Interagency HIV Study (WIHS) participants (301 WWH, 113 women without HIV from Brooklyn, New York City, and Chicago had baseline and 10-year BMI and fasting plasma leptin levels using commercial enzyme-linked immunosorbent assay (ng/mL); and demographically adjusted NP T scores (attention/working memory, executive function [EF], processing speed, memory, learning, verbal fluency, motor function, global) at 10-year follow-up. Multivariable linear regression analyses, stratified by HIV serostatus, examined associations between BMI, leptin, and NP. RESULTS: Over 10 years, women (baseline age 39.8 ±â€…9.2 years, 73% Black, 73% WWH) transitioned from average overweight (29.1 ±â€…7.9) to obese (30.5 ±â€…7.9) BMI. Leptin increased 11.4 ±â€…26.4 ng/mL (P < .001). Higher baseline BMI and leptin predicted poorer 10-year EF among all women (BMI ß = -6.97, 95% CI (-11.5 to -2.45) P = .003; leptin ß = -1.90, 95% CI (-3.03 to -0.76), P = .001); higher baseline BMI predicted better memory performance (ß = 6.35, 95% CI (1.96-10.7), P = .005). Greater 10-year leptin increase predicted poorer EF (P = .004), speed (P = .03), and verbal (P = .02) and global (P = 0.005) performance among all women, and WWH. Greater 10-year BMI increase predicted slower processing speed (P = .043) among all women; and among WWH, poorer EF (P = .01) and global (P = .04) performance. CONCLUSION: In middle-aged WIHS participants, 10-year increases in BMI and leptin were associated with poorer performance across multiple NP domains among all women and WWH. Trajectories of adiposity measures over time may provide insight into the role of adipose tissue in brain health with aging.

RESUMO

OBJECTIVE: CXCR4 (X4)-tropic HIV-1 was found previously to herald CD4 + cell depletion and disease progression in individuals who were antiretroviral-naive or took combination antiretroviral therapy (cART) for less than 5 years. We updated this finding by investigating whether the deleterious effect of X4-tropic strains is mitigated by long-term cART. DESIGN: We examined morbidity and mortality in relation to HIV-1 tropism and cART in 529 participants followed up to 18 years in the Women's Interagency HIV Study; 91% were women of color. METHODS: Plasma-derived HIV-1 tropism was determined genotypically. RESULTS: We categorized participants according to the number of visits reported on cART after initiation. Group 1: three or less visits, 74% of these participants reporting no cART; group 2: at least four visits and less than 70% of visits on cART; group 3: at least 70% of visits on cART. AIDS mortality rates for participants in each group with X4 virus compared with those with R5 virus exclusively were, respectively: 62 vs. 40% ( P  = 0.0088); 23% vs. 22% [nonsignificant (NS)]; 7% vs. 14% (NS). Kaplan-Meier curves showed accelerated progression to AIDS death or AIDS-defining illness in participants with three or less cART visits and X4 viruses ( P  = 0.0028) but no difference in progression rates stratified by tropism in other groups. Logistic regression found that HIV-1 suppression for at least 10 semiannual visits (≥5 years total) mitigated X4 tropism's deleterious effect on mortality, controlling for maximal viral load, and CD4 + nadir. CONCLUSION: Long-term cART markedly mitigated the deleterious effect of X4 viruses on AIDS morbidity and mortality. Mitigation was correlated with duration of viral suppression, supporting HIV-1 suppression as a crucial goal.

RESUMO

BACKGROUND: Aging in people with HIV is associated with increased risk of developing synergistic conditions such as neurocognitive impairment, polypharmacy, and falls. We assessed associations between polypharmacy (use of 5 or more non-ART medications), use of neurocognitive adverse effects (NCAE) medications, and odds of falls in women with HIV (WWH) and without HIV (HIV-). METHODS: Self-reported falls and medication use data were contributed semiannually by 1872 (1315 WWH and 557 HIV-) Women's Interagency HIV Study participants between 2014 and 2016. Polypharmacy and NCAE medication use were evaluated separately and jointly in multivariable models to assess their independent contributions to single and multiple falls risk. RESULTS: The proportion of women who reported any fall was similar by HIV status (19%). WWH reported both greater polypharmacy (51% vs. 41%; P < 0.001) and NCAE medication use (44% vs. 37%; P = 0.01) than HIV- women. Polypharmacy conferred elevated odds of single fall [adjusted odds ratio (aOR) 1.67, 95% CI: 1.36 to 2.06; P < 0.001] and multiple falls (aOR 2.31, 95% CI: 1.83 to 2.93; P < 0.001); the results for NCAE medications and falls were similar. Both polypharmacy and number of NCAE medications remained strongly and independently associated with falls in multivariable models adjusted for HIV serostatus, study site, sociodemographics, clinical characteristics, and substance use. CONCLUSIONS: Polypharmacy and NCAE medication use were greater among WWH compared with HIV-, and both were independently and incrementally related to falls. Deprescribing and avoidance of medications with NCAEs may be an important consideration for reducing fall risk among WWH and sociodemographically similar women without HIV.

RESUMO

Despite the use of highly active anti-retroviral treatment (HAART), cognitive impairment remains prevalent in HIV. Indeed a recent study suggested that in certain instances, stopping HAART was associated with improved cognitive function (Robertson et al. Neurology 74(16):1260-1266 2010). HAART is occasionally associated with cardiovascular pathology and such pathology may be associated with cognitive impairment. To explore these associations, we assessed the relative contributions of cardiovascular variables such as hypertension and atherosclerosis, of HIV and HAART to cognition. The participants were members of the Women's Interagency HIV Study. In the analysis of cross-sectional data using general linear models, we assessed the relationship between each cardiovascular variable and Stroop interference time and symbol digit modalities test while adjusting for age, HIV, education, depression, and race/ethnicity. We also analyzed the association of summary measures of HAART use with cognition. In multivariate models, significance was limited to carotid lesions and carotid intima-medial thickness quintile (CIMT) with Stroop interference time (for carotid lesions, coefficient = 10.5, CI 3.5 to 17.5, p = 0.003, N = 1,130; for CIMT quintile, coefficient = 8.6, CI = 1.7 to 15.4, p = 0.025, N = 1,130). The summary measures of protease inhibitor use and other HAART measures were in most cases not associated with cognitive score in multivariate models. We conclude that in the HAART era among middle-aged women with HIV, carotid disease may be significantly associated with some measures of cognitive impairment. In this cross-sectional study, we could detect neither positive nor negative effects of HAART on cognition.

RESUMO

OBJECTIVE: To estimate the cumulative incidence of self-reported influenza vaccination ("vaccination coverage") and investigate predictors in HIV-infected women. METHODS: In an ongoing cohort study of HIV-infected women in five US cities, data from two influenza seasons (2006-2007 n=1209 and 2007-2008 n=1161) were used to estimate crude and adjusted prevalence ratios (aPR) and 95% confidence intervals ([,]) from Poisson regression with robust variance models using generalized estimating equations (GEE). RESULTS: In our study, 55% and 57% of HIV-infected women reported vaccination during the 2006-2007 and 2007-2008 seasons, respectively. Using data from both seasons, older age, non-smoking status, CD4 T-lymphocyte (CD4) count > or =200 cells/mm(3), and reporting at least one recent healthcare visit was associated with increased vaccination coverage. In the 2007-2008 season, a belief in the protection of the vaccine (aPR=1.38 [1.18, 1.61]) and influenza vaccination in the previous season (aPR=1.66 [1.44, 1.91]) most strongly predicted vaccination status. CONCLUSION: Interventions to reach unvaccinated HIV-infected women should focus on changing beliefs about the effectiveness of influenza vaccination and target younger women, current smokers, those without recent healthcare visits, or a CD4 count <200 cells/mm(3).

RESUMO

OBJECTIVE: To describe development of the Positive Affect, Promoting Positive Engagement, and Adherence for Life (APPEAL) program. METHOD: APPEAL is intended to increase HIV medication adherence through promotion of positive affect, and was developed through an iterative process involving 6 focus groups (N = 34) that elicited feedback on intervention content, followed by an individually administered prepilot of the entire intervention (N = 7). RESULTS: Participants provided feedback on important potential moderator variables, including depression, on mode of intervention administration, and on anticipated barriers and benefits to participation. Insights gained were used to finalize study procedures in preparation for a feasibility trial. For the feasibility trial, a total of 80 participants who, in the past 6 months have had at least one plasma HIV RNA >200 copies/mL, will be randomized to receive APPEAL or standard of care (N = 40 per group). Intervention group participants will receive 3 monthly, individually administered sessions, and all participants will have their medication adherence monitored and complete structured interviews at baseline and at 3 and 6 months. CONCLUSION: The APPEAL program is innovative in that it focuses on promoting self-regulation of positive emotions, an understudied approach to promoting chronic disease self-management behaviors such as HIV medication adherence. Findings from the feasibility trial will gauge suitability of the APPEAL intervention and evaluation methods for subsequent testing in a confirmatory trial and will examine changes in positive affect, the primary mechanism of change targeted in the intervention.

RESUMO

INTRODUCTION: Foreign-born persons comprise ~13% of the US population. Immigrants, especially women, often face a complex set of social and structural factors that negatively impact health outcomes including greater risk of HIV infection. We described socio-demographic, clinical and immunological characteristics and AIDs and non-AIDS death among foreign-born women living with HIV (FBWLWH) participating in the US Women's Interagency HIV Study (WIHS) in the US from 1994 to 2016. We hypothesized that FBW will experience higher AIDS-related mortality compared to US-born women (USBW). METHODS: The WIHS is a multicenter prospective observational cohort study of mostly women living with HIV (WLWH). The primary exposure in this analysis, which focused on 3626 WLWH, was self-reported country of birth collapsed into foreign-born and US born. We assessed the association of birthplace with categorized demographic, clinical and immunological characteristics, and AIDS/non-AIDS mortality of WLWH, using chi-squared tests. Proportional hazard models examined the association of birthplace with time from enrolment to AIDS and non-AIDS death. RESULTS: Of the 628 FBW, 13% were born in Africa, 29% in the Caribbean and 49% in Latin America. We observed significant differences by HIV status in socio-demographic, clinical and immunological characteristics and mortality. For both AIDS and non-AIDS caused deaths FBW WLWH had lower rates of death. Adjusting for year of study enrolment and other demographic/clinical characteristics mitigated FBW's statistical survival advantage in AIDS deaths Relative Hazard (RH = 0.91 p = 0.53), but did not substantively change the survival advantage in non-AIDS deaths RH = 0.33, p < 0.0001). CONCLUSION: Foreign-born WLWH exhibited demographic, clinical and immunological characteristics that are significantly different compared with women born in the US or US territory. After adjusting for these characteristics, the FB WLWH had a significantly lower hazard of non-AIDS but not AIDS mortality compared to women born in the US or a US territory. These findings of non-increased mortality can help inform models of care to optimize treatment outcomes among FBWLWH in the United States.

RESUMO

OBJECTIVE: To determine whether domain-specific neurocognitive (NC) impairments predict falls in HIV+ compared with HIV- women. DESIGN: Cross-sectional data analysis from 825 HIV+ and 392 HIV- women in the Women's Interagency HIV Study with NC testing within 2 years before falls surveys. METHODS: NC impairment (T score <40) was assessed in 7 domains: executive function, psychomotor speed, attention, learning, memory, fluency, and fine motor function. For domains associated with any fall within 6 months in simple logistic regression (P < 0.05), hierarchical regression models evaluated associations between NC impairment and odds of falling, adjusting for: (1) study site and HIV, (2) demographics, (3) comorbid conditions, (4) substance use/central nervous system active medications, and HIV-specific factors. RESULTS: Median age was higher in HIV+ than HIV- women (51 vs. 48 yrs); prevalence of falls was similar (19% HIV+, 16% HIV-). Overall, executive function [OR (odds ratio) = 1.82, 95% CI (confidence interval): 1.21 to 2.74; P = 0.004], psychomotor speed (OR = 1.59, 95% CI: 1.05 to 2.42, P = 0.03), and fine motor (OR 1.70, 95% CI: 1.11 to 2.61, P = 0.02) impairments were associated with greater odds of falls in fully adjusted models. In fully adjusted models, associations of executive function, psychomotor speed, and fine motor were nonsignificant among HIV+ women; conversely, among HIV- women, associations with impaired executive and fine motor functions were strengthened and remained significant. CONCLUSIONS: Cognitive impairment was associated with falls among middle-aged HIV- but not HIV+ women. Additional studies should elucidate mechanisms by which domain-specific NC impairment impacts fall risk among older HIV+ and HIV- women and how different factors modify relationships between cognition and falls.

RESUMO

Objectives: To identify factors associated with incarceration among women and examine the relationship between incarceration and human immunodeficiency virus (HIV)-related outcomes. Materials and Methods: We analyzed longitudinal data from 3324 women (2372 with HIV and 952 uninfected) from 2007 to 2016 in the Women's Interagency HIV Study, a U.S. cohort of women with and without HIV. Lifetime history of incarceration before first study visit was used as the outcome and then as a predictor for HIV outcomes and mortality. Using multivariable models, we assessed associations between socio-demographic, behavioral, and clinical characteristics and incarceration, and between incarceration and HIV outcomes, including mortality. Results: Overall, 1256 (38%) of women reported ever being incarcerated. Women who had a history of drug use had a 44% greater prevalence of incarceration compared with those who did not use drugs. Sexual minority women and women who experienced physical and sexual abuse had a 47% and 28%, respectively, greater prevalence of incarceration than heterosexual women and those not abused. For the 862 women with HIV and a history of incarceration, having an incarceration history was independently associated with less viral suppression (adjusted prevalence ratios = 0.95; confidence intervals [CI]:0.90-1.00 p = 0.04) and higher likelihood of death (adjusted hazard ratios = 1.39; CI:1.04-1.86 p = 0.03). Conclusions: Incarceration is common in this cohort and may put women with HIV at increased odds of worse HIV outcomes and mortality than those without a history of incarceration. Addressing the intersecting epidemics of HIV, substance use, and incarceration by providing needed treatment and resources and avoiding criminalization may improve health outcomes in vulnerable women with HIV.
