Clinical Trial: Pulmonary Complications of HIV Infection Study (PACS)

Study Status: Completed
Recruit Status: Completed
Study Type: Observational

Official Title:

Brief Summary: To evaluate the types, incidence, course, and outcome of pulmonary disorders in newly diagnosed cases of Acquired Immune Deficiency Syndrome (AIDS), newly diagnosed cases of AIDS-related complex (ARC) and newly diagnosed asymptomatic human immunodeficiency virus (HIV) infection.

Detailed Summary:

BACKGROUND:

Pulmonary infections as a group are the most commonly recognized life threatening disorders in patients with the AIDS. Although Pneumocystis carinii was the predominant pulmonary pathogen found in these patients, other organisms were clearly of importance as well, not with early years of the HIV epidemic only in patients with AIDS and ARC but in individuals with asymptomatic HIV infection.

In the mid-1980s, physicians who examined many AIDS patients had the impression that a shift was occurring in the types and incidence of pulmonary complications associated with HIV infection. For example, there appeared to be an increased incidence of serious infections caused by pyogenic bacteria and pulmonary and extrapulmonary infection with M. tuberculosis had been noted with increased frequency. Furthermore, lymphoid interstitial pneumonitis (LIP), which is diagnostic of AIDS in children under 13 years old who are HIV antibody positive, was diagnosed with increased frequency in adults. Nonspecific interstitial pneumonitis also appeared to be on the rise. Legionella pneumonia, in contrast to its increased incidence during 1981-83, was now seldom encountered. However, apart from the increased incidence of tuberculosis, a reportable disease, these other shifts in the incidence of pulmonary complications had not been verified.

Because diagnostic strategies in the development of new treatment regimens and new approaches for clinical research were dependent upon knowledge of the incidence and natural history of pulmonary complications associated with HIV infection, the collection of such information was important.
