AB The value of immunoscintigraphy with technetium-99m (99Tcm) labelled
anti-granulocyte monoclonal antibody (BW250/183) was studied
prospectively in human immunodeficiency virus (HIV-1) antibody-positive
patients presenting with fever without localizing symptoms or signs.
Twenty-three studies were performed in 23 patients and the results of
99Tcm-anti-granulocyte imaging were compared with the definitive
microbiological or cytological diagnosis. Twenty-one patients had an
infective cause of pyrexia, one patient had disseminated lymphoma and
one Kaposi sarcoma. 99Tcm-anti-granulocyte antibody imaging correctly
identified the sites of infection in only five (24%) patients, four of
whom had infective colitis (one also had bacterial pneumonia) and one of
whom had cellulitis. Sixteen foci of infection were not localized by
99Tcm-anti-granulocyte immunoscintigraphy (false-negative scans). Six of
these patients had Pneumocystis carinii pneumonia; other diagnoses in
this group included bacterial or fungal pneumonia and bacteraemia
secondary to line infections. 99Tcm-anti-granulocyte antibody did not
accumulate in the patients with disseminated lymphoma and Kaposi sarcoma
(true-negative scans). 99Tcm-anti-granulocyte imaging, therefore,
appears useful in identifying extrathoracic infection in HIV-1 positive
patients. Its lack of sensitivity for the identification of pulmonary
infection means that its role in the investigation of HIV-1
antibody-positive patients with fever without localizing symptoms or
signs is limited.
