Gender and ethnic differences in survival in a cohort of HIV positive clients

Conspiracy beliefs about HIV are related to antiretroviral treatment nonadherence among african american men with HIV

BACKGROUND

Medical mistrust is prevalent among African Americans and may influence health care behaviors such as treatment adherence. We examined whether a specific form of medical mistrust-HIV conspiracy beliefs (eg, HIV is genocide against African Americans)-was associated with antiretroviral treatment nonadherence among African American men with HIV.

METHODS

On baseline surveys, 214 African American men with HIV reported their agreement with 9 conspiracy beliefs, sociodemographic characteristics, depression symptoms, substance use, disease characteristics, medical mistrust, and health care barriers. Antiretroviral medication adherence was monitored electronically for one month postbaseline among 177 men in the baseline sample.

RESULTS

Confirmatory factor analysis revealed 2 distinct conspiracy belief subscales: genocidal beliefs (eg, HIV is manmade) and treatment-related beliefs (eg, people who take antiretroviral treatments are human guinea pigs for the government). Both subscales were related to nonadherence in bivariate tests. In a multivariate logistic regression, only treatment-related conspiracies were associated with a lower likelihood of optimal adherence at one-month follow-up (odds ratio = 0.60, 95% confidence interval = 0.37 to 0.96, P < 0.05).

CONCLUSIONS

HIV conspiracy beliefs, especially those related to treatment mistrust, can contribute to health disparities by discouraging appropriate treatment behavior. Adherence-promoting interventions targeting African Americans should openly address such beliefs.

Disordered sleep, nocturnal cytokines, and immunity: interactions between alcohol dependence and African-American ethnicity

Sleep disturbance is one of the most prominent complaints of alcohol-dependent patients. In view of recent evidence that the immune system is integrated with other homeostatic processes ultimately regulated by the brain, the influence of sleep on host defense mechanisms and the expression of proinflammatory and T helper cell cytokines deserves attention in alcohol dependence. Although not all immune alterations found in alcohol-dependent persons are related to disordered sleep, it is exceedingly important to know whether sleep influences immunity in alcoholism because of the recognized impact of disordered sleep on infectious disease risk. Conversely, feedback systems are also operating between the brain and the immune system, and abnormalities in the expression of cytokines might contribute to sleep disturbances in alcohol-dependent persons. In this review, we identify the immune alterations found in association with alcohol dependence and discuss the implications of these findings for infectious disease risk, with particular attention to the interaction between African-American ethnicity and alcoholism in contributing to this risk. We provide evidence that sleep disruption occurs in association with alcohol dependence and that African-American alcohol-dependent persons show greater abnormalities in sleep and sleep regulatory processes than shown by Euro-American alcohol-dependent persons. The relations among alcoholism, sleep, and immunity are discussed, with an emphasis on understanding how the cytokine network is altered during sleep in the African-American alcohol-dependent populations. The potential is to use cytokine agonists or antagonists to determine whether physiologic changes in cytokines have a role in the homeostatic regulation of sleep in human beings, which has tremendous implications for the development of novel treatments of alcohol-related sleep disorders.

Low socioeconomic status is associated with a higher rate of death in the era of highly active antiretroviral therapy, San Francisco

Highly active antiretroviral therapy (HAART) has dramatically improved survival after AIDS. The benefits of HAART have not been equally realized for all communities, however. We characterize the association of socioeconomic status (SES) with survival after AIDS diagnosis in San Francisco in the period before (1980-1995) and after (1996 - 2001) the wider use of HAART. Using citywide surveillance data, we examined differences in survival after AIDS diagnosis by neighborhood household income using Kaplan-Meier survival analysis and Cox proportional hazards analysis to adjust for significant covariates. Residing in higher SES neighborhoods significantly predicted better survival after AIDS from 1996 to 2001 (hazard ratio = 0.92 per $10,000 increase in neighborhood household income, 95% CI: 0.85-0.99) after adjusting for CD4 count at diagnosis, age, and injection drug user status. Persons living in poorer neighborhoods were less likely to use HAART at any time in the past compared with persons in wealthier neighborhoods. Moreover, no association between survival and neighborhood SES was evident in the era prior to the wide use of HAART. Finally, the difference in survival by neighborhood income level disappeared after controlling for the use of HAART, suggesting that use of or access to treatment explained the association. From 1996 to 2001, survival with AIDS was worse for people living in poorer neighborhoods compared with those living in wealthier neighborhoods of San Francisco as a result of unequal access to or use of HAART.

Trends in non-Hodgkin lymphoma (NHL) and HIV-associated NHL deaths in the United States

Since a significant number of lymphomas have been associated with the human immunodeficiency virus (HIV), the purpose of this study was to describe the impact of HIV infection on non-Hodgkin's lymphoma (NHL) mortality trends and demographics. Multiple-cause-of-death data for the United States from 1979 through 1996 were obtained from the National Center for Health Statistics, Centers for Disease Control and Prevention. Annual NHL deaths rates for the United States were calculated as the number of NHL deaths per 100,000 persons, based on estimates of the U.S. resident population. The time periods 1979-1982, 1986-1989, and 1993-1996 were examined for changes over time. To describe NHL and HIV infection mortality, the characteristics of NHL deaths with HIV infection listed anywhere on the death records were examined beginning in 1987. This study found that despite reports of a lower incidence rate of NHL among blacks with HIV/AIDS, death rates from lymphomas associated with HIV/AIDS have markedly increased in black males and females over time. It was also noted that in agreement with other studies, this study documented a decrease in NHL/HIV mortality in 1996.

A holistic life view of human immunodeficiency virus-infected African American women

Minority women represent the fastest growing segment of the population to acquire HIV/AIDS in the United States. Although African American women are a large proportion of this group, no published study has concentrated solely on a holistic view of the experiences of HIV-infected African American women. The primary purpose of this phenomenological pilot study was to describe the lives of five HIV-infected African American women. Audiotaped interviews were conducted and subsequently were examined, using Giorgi's steps of analysis. Twelve themes emerged from the data: violence, addiction, it couldn't happen to me, shock and denial, education, time, uncertainty, cycles, secretive nature of their lives, someone, survival, and children. It is clear, even from this small pilot study, that these women have complex experiences that must be better understood before effective health care interventions can be designed and implemented.

Protease inhibitor use among a community sample of people with HIV disease

OBJECTIVES

Protease inhibitors have become integral to HIV disease management. This paper examines sociodemographic factors affecting patient use and perceived knowledge of protease inhibitors, and the relationship between protease inhibitor use and perceived health.

METHODS

1034 people with HIV disease from a large AIDS services organization completed a mailed self-administered survey that assessed sociodemographics, protease inhibitor use and perceived knowledge, and perceived change in health status over the previous year. Multiple logistic regression was used to determine sociodemographic factors independently associated with protease inhibitor use and perceived knowledge, and perceived overall health status.

RESULTS

Two thirds (66%) of correspondents included in the sample were currently taking protease inhibitors and 52% reported being very knowledgeable about these medications. Adjusting for sociodemographic factors, those who were currently not taking protease inhibitors were more likely to be African American, non-English speaking, earning <$9600 U.S. annually, or uninsured. Among protease inhibitor users, those who reported less knowledge about the drugs were more likely to be nonwhite, earning <$9600 U.S. annually, and not college educated. Protease inhibitor use was independently associated with perceived improved overall health and having been college educated.

CONCLUSIONS

Further efforts should be directed toward increasing use and knowledge of protease inhibitors among disadvantaged populations.
