Brief Report: Heplisav-B Seroprotection in People With HIV: A Single-Center Experience.

BACKGROUND: Heplisav-B, a hepatitis B virus (HBV) vaccine with an immunostimulatory adjuvant, was FDA approved in 2017 for adults ≥18 years. In randomized controlled trials, Heplisav-B demonstrated seroprotection rates (SPR) of 90%-95% versus 65%-80% for Engerix-B. No studies have included people with HIV (PWH), and the SPR and its predictors in this population are unknown. SETTING: Quaternary care center HIV clinic. METHODS: This retrospective cohort study evaluated PWH aged ≥18 years without current HBV seroprotection (anti-HBV surface antibody level [anti-HBs] <10 mIU/mL) who were administered Heplisav-B. Patients without post-immunization titers were excluded. The primary outcome was the SPR, the proportion of participants with HBV seroprotection at any point after the first vaccination. RESULTS: Among 64 PWH included, median time to anti-HBs measurement after vaccination was 13 weeks. The median age was 58 years, 81% were men, and 95% had a viral load <200. The SPR was 81% in the entire cohort (and 86% in those without significant non-HIV immunosuppression), 79% in those with no prior HBV vaccination and no anti-HBc positivity, and 84% in those with prior vaccine nonresponse. Lower current and nadir CD4+ counts were associated with progressively lower seroprotection. CONCLUSION: In the first single-center retrospective study of Heplisav-B in PWH, the SPR compared favorably with the SPR seen among PWH from prior HBV vaccines across key subgroups. Given these findings, Heplisav-B should be considered for expanded use for HBV vaccination in PWH. Further research on the effectiveness of a repeat vaccination series or higher dosing in nonresponders is needed.

Functional deficits and other psychiatric associations with abnormal scores on the Montreal Cognitive Assessment (MoCA) in older HIV-infected patients.

OBJECTIVE: The authors assessed the association of physical function, social variables, functional status, and psychiatric co-morbidity with cognitive function among older HIV-infected adults. DESIGN: From 2012-2014, a cross-sectional study was conducted among HIV-infected patients ages 50 or older who underwent comprehensive clinical geriatric assessment. SETTING: Two San Francisco HIV clinics. PARTICIPANTS: 359 HIV-infected patients age 50 years or older. MEASUREMENTS: Unadjusted and adjusted Poisson regression measured prevalence ratios and 95% confidence intervals for demographic, functional and psychiatric variables and their association with cognitive impairment using a Montreal Cognitive Assessment (MoCA) score < 26 as reflective of cognitive impairment. RESULTS: Thirty-four percent of participants had a MoCA score of < 26. In unadjusted analyses, the following variables were significantly associated with an abnormal MoCA score: born female, not identifying as homosexual, non-white race, high school or less educational attainment, annual income < $10,000, tobacco use, slower gait speed, reported problems with balance, and poor social support. In subsequent adjusted analysis, the following variables were significantly associated with an abnormal MoCA score: not identifying as homosexual, non-white race, longer 4-meter walk time, and poor social support. Psychiatric symptoms of depressive, anxiety, and post-traumatic stress disorders did not correlate with abnormal MoCA scores. CONCLUSIONS: Cognitive impairment remains common in older HIV-infected patients. Counter to expectations, co-morbid psychiatric symptoms were not associated with cognitive impairment, suggesting that cognitive impairment in this sample may be due to neurocognitive disorders, not due to other psychiatric illness. The other conditions associated with cognitive impairment in this sample may warrant separate clinical and social interventions to optimize patient outcomes.

Loneliness in Older Adults Living with HIV.

We conducted a cross-sectional study among HIV-positive adults age ≥ 50 in San Francisco to evaluate the frequency of loneliness, characteristics of those who reported loneliness, and the association of loneliness with functional impairment and health-related quality of life (HRQoL). Participants (N = 356) were predominately male (85%); 57% were white; median age was 56. 58% reported any loneliness symptoms with 24% reporting mild, 22% moderate and 12% severe loneliness. Lonely participants were more likely to report depression, alcohol and tobacco use, and have fewer relationships. In unadjusted models, loneliness was associated with functional impairment and poor HRQoL. In adjusted models, low income and depression remained associated with poor HRQoL, while low income, higher VACS index and depression were associated with functional impairment. A comprehensive care approach, incorporating mental health and psychosocial assessments with more traditional clinical assessments, will be needed to improve health outcomes for the aging HIV-positive population.

RESUMEN: Realizamos un estudio transversal en adultos mayores de 50 años con VIH en San Francisco para evaluar la frecuencia de la soledad, características de aquellos que reportan soledad, y la asociación de la soledad con el deterioro funcional y la calidad de vida relacionada con la salud (HRQoL). Los participantes (N = 356) fueron principalmente hombres (85%); 57% de raza blanca, la mediana de edad fue 56 años. El 58% reportó cualquier síntoma de soledad con un 24% reportando soledad leve, 22% soledad moderada, y 12% soledad severa. En los participantes que refirieron soledad era más probable que reportaran depresión, consumo de tabaco o alcohol, y menos relaciones sociales. En modelos sin ajustar, la soledad estaba asociada con deterioro funcional y baja calidad de vida relacionada con la salud. En modelos ajustados, tener bajos ingresos y depresión continuaron teniendo asociación con una baja calidad de vida relacionada con la salud, mientras que tener bajos ingresos, un índice más alto de VACS y depresión estaban asociados con deterioro funcional. Un sistema de cuidado integral, incorporando la salud mental y valoraciones psicológicas y sociales con evaluaciones médicas tradicionales, serán necesarios para poder mejorar los índices de salud de las personas VIH positivas que envejecen.

Changes in Specific Substance Involvement Scores among SBIRT recipients in an HIV primary care setting.

BACKGROUND: Substance use is common among people living with HIV (PLHIV) and is associated with worse outcomes along the HIV care continuum. One potentially effective clinic-based approach to addressing unhealthy substance use is screening, brief intervention, and referral to treatment (SBIRT). METHODS: We conducted a two-arm randomized trial to examine the effects of a self-administered, computerized SBIRT intervention compared to a clinician-administered SBIRT intervention in an HIV primary clinic. Patients were surveyed before receiving the intervention and again at 1, 3, and 6 months. We administered the WHO Alcohol, Smoking and Substance Involvement Screening Test to determine Specific Substance Involvement Scores (SSIS) and to assign participants to categories of lower, moderate, or high risk to health and other problems for each substance. We collapsed moderate or severe risk responses into a single moderate-high risk category. Based on low rates of participation in the computerized arm, we conducted an "as treated" analysis to examine 6-month changes in mean SSIS among SBIRT intervention participants. RESULTS: For the overall sample (n = 208), baseline mean SSIS were in the moderate risk category for alcohol, tobacco, cannabis, cocaine, amphetamine, sedatives and opioids. Of those enrolled, 134 (64.4%) received the intervention, and 109 (52.4%) completed the 6-month follow up. There was a statistically significant decline in mean SSIS for all substances except tobacco and cannabis among participants who were at moderate-high risk at baseline. We also observed a statistically significant increase in mean SSIS for all substances except amphetamines and sedatives among participants who were at lower risk at baseline. CONCLUSIONS: Substance use among patients in this urban, safety-net, HIV primary care clinic was near universal, and moderate risk substance use was common. Among participants who received the SBIRT intervention, mean SSISs decreased among those at moderate-high risk at baseline, but increased among those at lower risk at baseline over the 6-month study period. Additional research should examine the clinical significance of SSIS changes for PLHIV, which SBIRT components drive changes in substance use scores, and what other interventions might support those patients at lower risk to maintain health and engagement along the HIV care continuum.

Food Insecurity and Aging Outcomes in Older Adults Living with HIV.

Little is known about food insecurity and its association with geriatric outcomes in older people living with HIV (PLWH). This was a cross-sectional study of 230 HIV-infected patients aged 50 and older recruited in December 2012 through June 2016. Poisson logistic regression models estimated the prevalence ratio (PR) and 95% confidence intervals (CI) for the association between food insecurity and the following geriatric outcomes: frailty, physical health and function, social support, mental health and cognition, and behavioral health. 157 (68%) participants were food secure, 35 (15%) had low food security, and 38 (17%) had very low food security. After adjusting the analyses for other significant covariates, at risk alcohol or drug use (PR = 3.14; 95% CI 1.75-5.64), being sedentary (PR = 3.30; 95% CI 1.09-10.00) depressive symptoms (PR = 1.77; 95% CI 1.13-2.76), and dependent instrumental activities of daily living (PR = 2.46; 95% CI 1.13-5.36) were significantly associated with very low food security. These results highlight a need for structural HIV interventions that incorporate targeted food assistance strategies for older PLWH.

Prevalence of Substance Use in an HIV Primary Care Safety Net Clinic: A Call for Screening.

Substance use complicates HIV care and prevention. Primary care clinics are an ideal setting to screen for and offer interventions for unhealthy alcohol and drug use; however, few HIV clinics routinely screen for substance use. We enrolled 208 clinic patients at an urban underserved HIV primary care clinic. We screened the patients for substance use with the Alcohol, Smoking, and Substance Involvement Score Test and measured urine toxicology. Of the 168 participants who completed screening, the majority reported tobacco or nonprescribed substance use in the previous 3 months. More African American participants reported low or no risk amphetamine use compared to Hispanic, White, or Other race participants (p < .001). Implementing standard clinic practice for screening and assessing substance use in HIV primary care clinics is needed.

Critical Review: When the Party is Over: A Systematic Review of Behavioral Interventions for Substance-Using Men Who Have Sex with Men.

Because problematic patterns of alcohol and other substance use are prevalent drivers of the HIV/AIDS epidemic, comprehensive interventions are needed for substance-using men who have sex with men (SUMSM). We conducted a systematic review of 12 randomized controlled trials (RCTs) of behavioral interventions for reducing condomless anal intercourse (CAI) in SUMSM. Three RCTs observed that cognitive behavioral or motivational interviewing interventions achieved a 24% to 40% decrease in CAI. Interventions also tended to demonstrate greater efficacy for reducing CAI and substance use among those who had lower severity of substance use disorder symptoms. Although behavioral interventions for SUMSM are one potentially important component of biobehavioral HIV/AIDS prevention, further research is needed to examine whether integrative approaches that cultivate resilience and target co-occurring syndemic conditions demonstrate greater efficacy. Multilevel intervention approaches are also needed to optimize the effectiveness of pre-exposure prophylaxis and HIV treatment as prevention with SUMSM.

Geriatric Assessments and Association With VACS Index Among HIV-Infected Older Adults in San Francisco.

OBJECTIVES: To perform geriatric assessments in older HIV-infected adults in San Francisco and examine the association with age and the Veterans Aging Cohort Study (VACS) index scores. METHODS: A cross-sectional study was conducted from 2012 to 2014 among HIV-infected patients ≥50 years at 2 San Francisco-based HIV clinics. We evaluated 4 health domains: (1) physical health and function (activities of daily living), instrumental activities of daily living (IADL), falls, gait speed, (2) social support (physical and perceived support, loneliness), (3) mental health (depression, anxiety, posttraumatic stress disorder) and cognition, and (4) behavioral and general health (antiretroviral adherence and quality of life). Contingency table and rank-sum analyses examined associations between these domains with age and VACS index scores. RESULTS: Three hundred fifty-nine patients completed assessments (median age 57; 85% male; 57% white; 72% >high school education). On functional assessment, 39% reported dependence with ≥1 IADL, and 40% reported falls in the previous year. Fifty-eight percent experienced loneliness, 60% the lowest levels of perceived social support, 55% depression, and 12% posttraumatic stress disorder. Forty percent had possible mild cognitive impairment. Thirty percent reported poor or fair quality of life. Older age was associated with lower CD4 counts, balance problems, slower gait, lower anxiety, poorer general health, and higher antiretroviral adherence. VACS Index score was associated with dependence in ≥1 IADL and antiretroviral adherence. CONCLUSION: In a large sample of older HIV-infected adults, multiple significant aging-related conditions were identified. Integrating geriatric assessment tools into HIV/AIDS clinical care may help target interventions to optimize clinical care and quality of life for older HIV-infected individuals.

Using Interactive Web-Based Screening, Brief Intervention and Referral to Treatment in an Urban, Safety-Net HIV Clinic.

Substance use among people living with HIV is high, and screening, brief intervention, and referral to treatment (SBIRT) is an evidence-based approach to addressing the issue. We examined whether patients would participate in a technology-based SBIRT program in an urban HIV clinic. An SBIRT intervention was programmed into the clinic's web-based patient portal linked to their personal health record. We examined: demographic, health, HIV, and substance use characteristics of participants who completed the web-based intervention compared to those who did not. Fewer than half of the 96 participants assigned to the web-based SBIRT completed it (n = 39; 41 %). Participants who completed the web-based intervention had significantly higher amphetamine SSIS scores than those who did not complete the intervention. Participants whose substance use is more harmful may be more motivated to seek help from a variety of sources. In addition, it is important that technology-based approaches to behavioral interventions in clinics take into consideration feasibility, client knowledge, and comfort using technology.
