In a prospective study of 72 human immunodeficiency virus (HIV) positive
patients presenting with fever and breathlessness, a non-invasive
management protocol, incorporating a scanning technique using
radioactively labelled diethylenetriamine penta acetate (DTPA) and
sputum induction, was found to be highly sensitive and specific in the
early detection of Pneumocystis carinii pneumonia (PCP). At
presentation, the DTPA scan was abnormal in 34 of 36 cases of PCP,
irrespective of smoking history, whilst the chest radiograph was
diffusely abnormal in 21 cases. Sputum induction identified 7 of 14
patients with PCP in the first six months of its use and 7 of 10
patients over the last six months. The DTPA lung scan and induced sputum
examination are non-invasive techniques which can be used to investigate
out-patients. In combination they detected all cases of PCP at
presentation, reduced the need for bronchoscopy, resulted in a low case
fatality (5.4%) and reduced the need for admission.
