Brief Summary: To quantitate in an HIV-infected population the percentage of patients demonstrating the booster phenomenon attainment of a positive response to a second tuberculin purified protein derivative skin test when the first skin test was negative to determine the relationship between the booster phenomenon and CD4-positive lymphocyte cell counts to detect any relationship between the booster phenomenon and HIV exposure category

The accuracy of skin testing to detect Mycobacterium tuberculosis MTb infection is dependent upon the hosts ability to mount a delayed-type hypersensitivity DTH reaction however the DTH response may be impaired or absent in patients with impaired cell-mediated immunity a classic characteristic of HIV infection Patients in whom immunity is diminished but not absent may test negative the first time a purified protein derivative skin test for MTb is administered but if the same skin test is repeated a positive DTH response may then be elicited This occurrence is known as the booster phenomenon

Patients who have had a negative purified protein derivative PPD skin test for M tuberculosis within 7-28 days prior to study entry will receive a second PPD test by the Mantoux method 5 TU intradermally to the volar aspect of the forearm Skin tests will be read 48-72 hours after application Patients with a positive skin test defined as an induration or small hard knot of 5 mm or greater forming beneath the skin will be referred to their primary physicians for further evaluation
