Insights
The death of a partner can negatively impact immune function in men with HIV (human immunodeficiency virus). Bereavement is linked to immune changes that may worsen HIV progression.
Area of Science:
- Psychoneuroimmunology
- Immunology
- HIV/AIDS Research
Background:
- The death of an intimate partner is a significant stressor.
- The impact of bereavement on immune function in HIV-positive individuals is not fully understood.
Purpose of the Study:
- To investigate immune changes in HIV-seropositive men following the death of their partner.
- To explore the association between depressed mood and these immune alterations.
Main Methods:
- Comparison of immune parameters between bereaved and nonbereaved HIV-positive gay men.
- Assay of immunological markers (immune activation, T-cell proliferation) before and after bereavement.
- Control for lifestyle factors (substance use, AZT).
Main Results:
- HIV-positive bereaved men showed increased immune activation post-bereavement.
- A significant decrease in T-cell proliferative response was observed in bereaved men.
- These immune changes were independent of drug use, alcohol, smoking, or AZT.
Conclusions:
- Partner death is associated with detrimental immune changes in HIV-positive men.
- These changes are relevant to HIV disease progression.
- Bereavement represents a significant psychosocial stressor impacting immune health in this population.
Abstract:
The objectives of this study were to determine 1) whether immune changes relevant to HIV progression occurred in HIV-seropositive men after the death of their intimate partner, and 2) whether depressed mood was associated with these immune changes. The bereaved group consisted of 39 gay men whose intimate partners had died of AIDS over the past year; the nonbereaved group consisted of 39 age- and HIV serostatus-matched nonbereaved men. Immunological parameters were assayed from blood samples drawn before and within 1 year after the death of the partner (bereaved group) or over an equivalent time period (nonbereaved group). In the HIV-seropositive bereaved men only, a significant increase in immune activation and a significant decrease in the proliferative response to phytohemagglutinin occurred after the death of the partner. These immunological changes were not explained by the use of recreational drugs, alcohol, cigarettes, or AZT. These data indicate that the death of an intimate partner in HIV-positive men is associated with immune changes that are relevant to HIV progression.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
