Abstract
To determine whether populations with high cumulative incidence of acquired immunodeficiency syndrome (AIDS) experienced increased deaths from sepsis, central nervous system abscess, or endocarditis, New Jersey [USA] AIDS patients were grouped according to their age, sex, race, and residence-specific cumulative incidence of AIDS since the onset of the AIDS epidemic. Between 1980 and 1986, among 25-44 year olds in the highest cumulative incidence groups for AIDS, sepsis mortality increased from 3.3 to 15.2 deaths/100,000/year, an increase of 11.9 deaths/100,000/year (95% confidence interval (6.9, 17.0) deaths/100,000/year); mortality from central nervous system abscesses increased from zero to 1.7 (0.1, 3.2) deaths/100,000/year; and mortality from endocarditis increased from 0.8 deaths/100,000/year to 2.4 deaths/100,000/year an increase of 1.6 (-0.5, 3.7) deaths/100,000/year. Age-matched New Jersey patient populations with low cumulative incidence of AIDS did not sustain a similar increase. The HIV disease-associated increase in sepsis mortality among young populations represents a new component of the substantial increase in U.S. sepsis mortality that occurred over the last two decades, but was previously limited to older populations.
