The acquired immune deficiency syndrome (AIDS) has affected more than 2,600 persons since 1981, with the number of reported cases rising exponentially. The disease is characterized by a deficiency in the cell-mediated immune system, which allows entrance to a host of opportunistic infections as well as tumors. The most common infection associated with AIDS is Pneumocystis carinii pneumonia, a previously uncommon infection of immunocompromised hosts. The most common neoplasm associated with AIDS is an otherwise rare skin tumor, Kaposi's sarcoma. AIDS is most often seen in homosexuals and intravenous-drug abusers, but the spectrum of the disease is widening and now includes other high-risk groups. The pulmonary manifestations of AIDS range from a nonproductive cough to acute respiratory failure. Once hospitalized, the AIDS patient may require several diagnostic and therapeutic services from respiratory care personnel. We review the epidemiology of this new syndrome, provide the basic framework for an understanding of the immunologic dysfunction in AIDS victims, review the clinical manifestations, and discuss the implications of the communicability of AIDS for the respiratory care practitioner.
