Nuclear medicine and AIDS.
The human immunodeficiency virus (HIV) infection and its associated illnesses in a relatively young population of patients provides an expanding role for nuclear medicine. The disease enforces a review of each department's infection control procedures. It also necessitates a widening of the differential diagnosis in high risk patients. It has also resulted in an increase in the number of patients presenting with diseases such as Pneumocystis carinii pneumonia, Kaposi's sarcoma etc. which prior to the HIV epidemic were extremely rare. Thus in high risk patients the interpretation of abnormalities in nuclear medicine scans needs to include the spectrum of opportunistic infections and unusual tumours. The presence of opportunistic infections in the severely immunocompromised patient has lead to the development of techniques not normally used, i.e. lung 99Tcm-diethylenetriamine pentaacetate (DTPA) transfer/clearance, donor leukocyte scanning to allow rapid diagnosis of an abnormality. Radionuclide techniques are also used to monitor the effect of therapy directed at the HIV itself or against opportunistic infections. This review covers aspects of infection control as well as the use of radionuclides to investigate specific problems related to HIV infection and therapy of the associated disease processes.
