The mortality rate associated with Staphylococcus aureus prosthetic valve endocarditis (PVE) remains high. To identify clinical events associated with an increased risk of death among patients with S. aureus PVE and to evaluate the role of valve replacement surgery in reducing mortality, we conducted a retrospective cohort study of patients who met strict criteria for definite S. aureus PVE. The primary endpoint for the study was survival at 3 months from the date of diagnosis. S. aureus PVE was diagnosed in 33 patients. Of these, 14 (42%) died within 90 days of the diagnosis. Cardiac complications were detected in 22 (67%), and central nervous system (CNS) complications were detected in 11 (33%). A stepwise logistic regression multivariate model demonstrated that cardiac complications, but not CNS complications, were associated with increased mortality and that performing valve replacement surgery during antibiotic therapy was associated with decreased mortality. These associations were confirmed by using a Cox proportional hazards model with time-dependent covariates to control for survival bias. Performing valve replacement surgery during antimicrobial therapy will reduce the mortality among patients with S. aureus PVE, even those without evidence of cardiac complications.
While numerous studies examine methamphetamine use and associated risky sexual behaviors in HIV-uninfected individuals, few studies have surveyed HIV-infected individuals in the health care setting. To assess the frequency and trends of methamphetamine use, sexual activity, injection drug use, patient-provider communication, and medication adherence among HIV-infected persons in care, we administered a one-page anonymous survey in 2004 and 2006. The survey was conducted at the two University of California, San Francisco outpatient HIV clinics: at Moffitt Hospital (Moffitt), serving primarily privately insured patients, and at San Francisco General Hospital (SFGH), a county hospital serving primarily patients who are uninsured or publicly insured. In 2006, 39% of men who have sex with men (MSM), 33% of heterosexual men, and 11% of women reported methamphetamine use in the prior 12 months. Methamphetamine use was significantly associated with an increased number of sex partners among MSM and heterosexual men, and poor anti-retroviral medication adherence. Among MSM, methamphetamine use was more common at the SFGH clinic. Between 2004 and 2006, reported methamphetamine use in the last 12 months decreased among MSM at Moffitt (38 to 20%, p<0.01), but increased at SFGH (40 to 50%, p<0.05). Among methamphetamine users we found a high frequency of injection of methamphetamine, which increased at SFGH from 38 to 55%, p<0.05. Patient-provider communication regarding methamphetamine use has increased from 2004 to 2006 but no significant change has been found for providers asking patients about sexual activity. Overall, we found methamphetamine use to be common among HIV-infected patients in care, and associated with an increased number of sex partners, a high frequency of injection drug use, and poor adherence to anti-retroviral medications. These findings support the need for improved screening and clinic-based interventions to reduce and treat methamphetamine abuse and associated high risk sexual behaviors.
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.
Antiretroviral nonadherence is a strong determinant of virologic failure and is negatively correlated with survival. HIV-positive African American youth have lower antiretroviral adherence and treatment engagement than other populations. We assessed the feasibility and acceptability of a telehealth (remote videoconferencing) medication counseling intervention as an innovative approach to address these disparities. HIV-positive African American youth (18-29 years old) on antiretrovirals were enrolled in a telehealth medication counseling session, followed by a semi-structured qualitative interview to explore likes/dislikes of the format, modality, and content; potential impact on adherence; privacy issues; and interaction quality. Fourteen participants with a mean age of 24 years, who were 86% male, and had a mean self-reported adherence in the past month of 89%, were interviewed. Participants stated that they liked telehealth, would use it if offered in clinic/research settings, and indicated that their privacy was maintained. Participants described telehealth as convenient and efficient, with positive impact on their knowledge. Telehealth provided a modality to interact with providers that participants described as less intimidating than in-person visits. Telehealth is feasible and acceptable for delivering medication counseling to HIV-positive African American youth when conducted in a controlled clinical setting and may improve quality of patient-provider dialogue. Use of telehealth may lead to more disclosure of treatment difficulties, increased patient comfort, and improved health education.
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 2012-2014 among HIV-infected patients ≥ 50 years at two San Francisco-based HIV clinics. We evaluated four health domains: 1) physical health and function (Activities of Daily Living [ADL], Instrumental ADL [IADL], falls, gait speed, 2) social support (physical and perceived support, loneliness), 3) mental health (depression, anxiety, post-traumatic 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 359 patients completed assessments (median age 57; 85% male; 57% Caucasian; 72% >high school education). On functional assessment, 39% reported dependence with ≥1 IADL, and 40% reported falls in the previous year. 58% experienced loneliness, 60% the lowest levels of perceived social support, 55% depression, and 12% PTSD. 40% had possible mild cognitive impairment. 30% 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.
