Are immunological markers, social and personal resources, or a complaint-free state predictors of progression among HIV-infected patients?

Neuropsychiatric complications of aging with HIV

Persons over age 50 are not only aging with human immunodeficiency virus (HIV) infection but also represent a high proportion of new HIV infections. Neuropsychiatric symptoms, including depression, cognitive impairment, and substance abuse, are very common in individuals infected with HIV. However, there is little understanding of the relationship between these HIV-related comorbid conditions in newly infected elderly patients compared to uninfected elderly and those who have survived after 20 years of HIV/AIDS. We summarize the current theories and research that link aging and HIV with psychiatric illnesses and identify emerging areas for improved research, treatment, and patient care.

Do positive psychosocial factors predict disease progression in HIV-1? A review of the evidence

Adding to a traditional stress perspective, behavioral medicine has been focusing increasingly on investigating the potential impact of positive psychosocial factors on disease course in HIV. Dispositional optimism, active coping, and spirituality show the most evidence for predicting slower disease progression, although the data are not entirely consistent. Findings for the role of social support are mixed, although indications are that it may be particularly helpful at later stages of illness. Many of the other constructs (positive affect, finding meaning, emotional expression/processing, openness, extraversion, conscientiousness, altruism, and self-efficacy) have only been examined in one or two studies; results are preliminary but suggestive of protective effects. Plausible behavioral and biological mechanisms are discussed (including health behaviors, neurohormones, and immune measures) as well as suggestions for clinicians, limitations, future directions, and a discussion of whether these constructs can be changed. In conclusion, investigating the importance and usefulness of positive psychosocial factors in predicting disease progression in HIV is in its beginning scientific stages and shows good initial evidence and future promise.

Symptom management in HIV/AIDS: advancing the conceptualization

For people living with HIV, symptoms related to the disease, comorbidities, and treatment side effects make symptom management essential. Poorly managed symptoms result in reduced medication adherence, disease progression, and lower quality of life. The Self-regulatory HIV/AIDS Symptom Management Model is a conceptual model that describes how persons living with HIV/AIDS manage their symptoms. The model links symptom experience, symptom management, social support, adherence, and health-related quality of life. It can assist nurses, through a multidimensional approach to illness management, to enhance symptom assessment, better understand factors influencing symptom experience, and to improve symptom management among people living with HIV/AIDS.

HIV disease progression: depression, stress, and possible mechanisms

There is much interest in whether depression and stress may explain the wide variability in the disease course of patients infected with human immunodeficiency virus (HIV). This article summarizes the large body of evidence examining whether depression and stress may have an impact on immune- and disease-related parameters in HIV disease. Furthermore, we review what is known about the underlying biological mechanisms of HIV disease, such as alterations in glucocorticoids and catecholamines, which may help explain these psychoimmune relationships. Our review of the literature finds substantial evidence that chronic depression and stressful events may affect HIV disease progression. We know little, however, regarding the biological mechanisms that may account for these relationships. More research is warranted to investigate how depression and stress might impact HIV disease progression and what types of interventions might mitigate the negative impact of chronic depression and trauma.

The effects of depression, stressful life events, social support, and coping on the progression of HIV infection

This article reviews recent findings concerning the role of psychosocial factors on the progression of HIV. Specifically, we examine the role of depression, stressful life events, social support, and coping on changes in CD4 T-lymphocytes and other indicators of HIV disease progression. Studies have yielded important evidence that depression, stressful life events, low social support, and denial coping may have a detrimental impact on HIV disease course. Delineating the role of psychosocial factors on HIV disease progression may aid in the development of new interventions for this devastating disease.

Stress and coping: the psychoneuroimmunology of HIV/AIDS

A considerable body of evidence, reviewed in this chapter, suggests that psychosocial factors play an important role in progression of HIV infection, its morbidity and mortality. Psychosocial influences relating to faster disease progression include life-event stress, sustained depression, denial/avoidance coping, concealment of gay identity (unless one is rejection-sensitive), and negative expectancies. Conversely, protective psychosocial factors include active coping, finding new meaning, and stress management. In studying long survivors of HIV/AIDS, our group has found protective effects on health of life involvement, collaborative relationship with doctor, emotional expression, depression (conversely), and perceived stress (conversely). Reviewed and discussed are psychoneuroimmunological pathways by which immune and neuroendocrine mechanisms might link psychosocial factors with health and long survival. Finally, biological factors are also a major determinant of disease progression and include genetics and age of the host, viral strain and virulence, medication and several immune response factors on which psychosocial influences could impact.
