OBJECTIVES: To assess the efficacy of 67Gallium lung scan at the early detection of the Pneumocystis Carinii Pneumonia (PCP). METHODS: 10 patients have to be studied (9 males, 1 female; median age 28, 6IVDU, 2 homosexual men, 2 heterosexual transmission) without respiratory symptomatology, with CD4 less than 500 mm (ranged from 30-450 with a mean of 124) and with a normal chest radiography. All of them underwent a 67Gallium lung scan. RESULTS: 2 patients had a bilateral diffused imaging, for which reason they underwent a bronchoscopy, so it remained apart in the bronchoalveolar lavage pneumocystis carinii. One month ago the first patient showed an episode of cerebral toxoplasmosis with a quantity of CD4 77 and Pa O2 97. The second patient showed a Kaposi's Sarcoma with a quantity of CD4 60 and Pa O2 95. CONCLUSIONS: In accordance with these information, we believe that 67Gallium lung scan would be useful for patients without respiratory symptomatology with a normal chest radiography, for those who have a diagnosis of disease associated with infection because of the HIV and/or those who have the quantity of CD4 less than 200. There is another point to determine, that is the relation cost-benefits of the method 67Gallium lung scan at the early detection of PCP.
