HIV diagnosis in older adults

Area of Science:

• Gerontology
• Infectious Diseases
• Immunology

Background:

• Individuals over 50 diagnosed with HIV infection exhibit elevated morbidity and mortality rates.
• Limited understanding exists regarding clinical presentation variations in older HIV-diagnosed populations.

Purpose of the Study:

• To compare clinical presentation and outcome markers in individuals diagnosed with HIV aged 60 and over versus those aged 50-59.
• To identify specific health risks and outcomes associated with later-life HIV diagnosis.

Main Methods:

• Retrospective analysis of HIV-diagnosed individuals over a ten-year period.
• Comparison of demographic, clinical presentation, and outcome data between age groups (≥60 vs. 50-59).

Main Results:

• The ≥60 age group presented with significantly lower median CD4 cell counts (111 vs. 249) and a higher proportion with CD4 counts <50 (33% vs. 15%).
• AIDS-defining illnesses were more frequent at diagnosis in the ≥60 group (38% vs. 4%).
• Mortality rates were substantially higher in the ≥60 group (38% vs. 4% at follow-up).

Conclusions:

• Individuals aged 60 and over diagnosed with HIV show poorer clinical markers at presentation, including lower CD4 counts and more AIDS-defining illnesses.
• This age group faces a significantly increased risk of adverse outcomes and mortality.
• Further research is essential to understand and improve survival for older adults diagnosed with HIV, recognizing them as a distinct population needing specific attention.
