AIDS epidemiology and pathology. Implications for intensive care units

The acquired immunodeficiency syndrome (AIDS) evolves from infection with the human immunodeficiency virus (HIV). The HIV attacks the hosts' immune and neuroendocrine systems, rendering the host susceptible to a myriad of chronic and acute conditions requiring intensive care. This article reviews epidemiologic and pathologic trends associated with HIV infections that have the potential to increase demands for admission to intensive care units. Research describing potential predictors of survival among patients with HIV-related conditions is also described. In addition, possible implications for practice, education, and research are discussed.
