AIDS Population

Abstract: This review focuses on the “real world” implications of infection with HIV/AIDS from a neuropsychological perspective. Relevant literature is reviewed which examines the relationships between HIV-associated neuropsychological impairment and employment, driving, medication adherence, mood, fatigue, and interpersonal functioning. Specifically, the relative contributions of medical, cognitive, psychosocial, and psychiatric issues on whether someone with HIV/AIDS will be able to return to work, adhere to a complicated medication regimen, or safely drive a vehicle will be discussed. Methodological issues that arise in the context of measuring medication adherence or driving capacity are also explored. Finally, the impact of HIV/AIDS on mood state, fatigue, and interpersonal relationships are addressed, with particular emphasis on how these variables interact with cognition and independent functioning. The purpose of this review is to integrate neuropsychological findings with their real world correlates of functional behavior in the HIV/AIDS population.

Abstract: The aim of this study was to describe smoking prevalence and smoking behavior in a multiethnic low-income HIV/AIDS population. A cross-sectional survey design was used. The study site was Thomas Street Clinic, an HIV/AIDS care facility serving a medically indigent and ethnically diverse population. Demographic, disease status, behavioral, and psychosocial variables were assessed by participant self-report. Surveys were collected from 348 study participants. Demographic composition of the sample was 78% male, 25% White, 44% Black, and 29% Hispanic. Study participants had a mean age of 40.2 years (SD=7.8). The HIV exposure profile of the sample was diverse: 46% men who have sex with men, 35% heterosexual contact, and 11% injection drug use. Prevalence of current cigarette smoking in the sample was 46.9%. Among participants with a lifetime history of smoking 100 or more cigarettes (62.8%), only 26.6% were currently abstinent, lower than the 48.8% rate seen in the general population. Multiple logistic regression analysis indicated that race/ethnicity, education level, age, and heavy drinking were significantly associated with smoking status. Hispanics were less likely than Whites were to smoke, younger participants were less likely than older participants were to be current smokers, and heavy drinkers were more likely to be current smokers than were those who were not heavy drinkers. As education level increased, the likelihood of smoking decreased and the likelihood of quitting increased. The high smoking prevalence in this HIV/AIDS population demonstrates the need for smoking cessation interventions targeted to the special needs of this patient group.

Abstract: BACKGROUND The authors sought to determine whether the availability of highly active antiretroviral therapy (HAART) coincided with changes in the epidemiology of acquired immunodeficiency syndrome (AIDS)-related non-Hodgkin lymphoma (NHL). METHODS Cancer registry data from 1988–2000 were linked with AIDS registry data from 1981 to July 2003 for San Diego County to identify 537 AIDS-NHL patients. By using the total number of patients with AIDS who were alive as of July 1 annually as the AIDS population denominator, the average annual incidence of NHL was estimated among patients with AIDS for the pre-HAART period (1988–1995) and post-HAART period (1996–2000). The chi-square test was used to compare proportions, and a Cox proportional hazards model was used to compare survival between the pre-HAART and post-HAART periods. RESULTS The incidence of NHL decreased from 29.6 per 1000 person-years pre-HAART to 6.5 per 1000 person-years post-HAART. The proportion of patients who had NHL of central nervous system (CNS) origin decreased from 28% pre-HAART to 17% post-HAART. Among patients with systemic NHL, 54% received chemotherapy pre-HAART, and 72% received chemotherapy post-HAART. The percentage of intermediate-grade NHL increased from 33% pre-HAART to 49% post-HAART, and the percentage of high-grade NHL decreased from 38% to 19%, respectively. A diagnosis of human immunodeficiency virus infection preceding the NHL diagnosis and Stage IV NHL were associated with worse survival, whereas a diagnosis of NHL in the post-HAART period and chemotherapy were associated with better survival. The median survival was 4 months pre-HAART and 9 months post-HAART. CONCLUSIONS Since the introduction of HAART, there has been a decrease in the incidence of systemic and CNS NHL among patients with AIDS. Among patients with systemic, AIDS-related NHL, there has been decreased high-grade histology, increased use of chemotherapy, and improved survival. Cancer 2006. © 2005 American Cancer Society.

Abstract: A number of studies have demonstrated that pain is dramatically undertreated among patients with AIDS and that opioids in particular are rarely prescribed. To date, however, there has been no systematic attempt to examine patient-related barriers to the management of pain in AIDS. This study examines potential patient-related barriers to pain management in patients with AIDS using the Barriers Questionnaire (Ward et al., Pain, 52 (1993) 319-324), and assesses gender, racial, and other demographic differences in the endorsement of these barriers. We surveyed 199 ambulatory patients with AIDS, recruited from numerous sites in New York City, as part of an ongoing study of pain and quality of life in ambulatory AIDS patients. In addition to obtaining demographic and medical data, we administered a number of self-report questionnaires including the Brief Pain Inventory (BPI), the Brief Symptom Index (BSI), the Beck Depression Inventory (BDI), and the Memorial Symptom Assessment Scale (MSAS). Barriers to pain management were assessed using a modified version of the Barriers Questionnaire (BQ), including the original 27 questions from this self-report instrument along with an additional 12 items developed for an AIDS population. Results indicated that the most frequently endorsed BQ items were those concerning the addiction potential of pain medications and physical discomfort associated with opioid administration (e.g. injections) or side effects (e.g. nausea, constipation). There were no associations between age, gender, or HIV transmission risk factor and total scores on the BQ; however, Caucasian patients endorsed significantly fewer BQ items than did non-Caucasian patients and years of education was negatively correlated with BQ scores. Scores on the BQ were also significantly correlated with number of physical symptoms (MSAS) and scores on several self-report measures of psychological distress (the BSI Global Distress Index, BDI total scores). Patient-related barriers (i.e. BQ total scores) were significantly associated with undertreatment of pain (as measured by the Pain Management Index), and added significantly to the prediction of undertreatment in a logistic regression analysis, even after controlling for the impact of gender, education and IDU transmission risk factor. These data suggest that patient-related barriers to pain management may add to the already considerable likelihood of undertreatment of AIDS-related pain.
