Abstract
Clinical evaluation was retrospectively made of the results of serological diagnostic methods using plasma and/or sera of patients for the diagnosis of aspergillosis, candidosis, and pneumocystosis. Specimens were drawn from 8 patients with invasive aspergillosis, 3 with aspergilloma, 9 with candidosis, 4 with pneumocystosis, and 15 with no fungal infections. In invasive aspergillosis, the sensitivities of the (1-3)-beta-D-glucan measurement test using chromogenic and turbidimetric methods were 78.6% and 82.1%, with specificities of 75% and 87.5%, respectively. The sensitivity of the Pastorex Aspergillus test for invasive aspergillosis was 16.7%, with a specificity of 92.3%. In candidosis, the sensitivities of the (1-3)-bata-D-glucan test using the above two methods were 84.2% and 100%, with specificities of 75% and 87.5%, respectively. The sensitivity of the CAND-TEC test and the Pastorex Candida test for candidosis were 68.8% and 16.7%, with specificities of 57.1% and 100%, respectively. These results indicate that the (1-3)-bata-D-glucan measurement methods are more reliable in clinical application than the other antigen detection methods, but they still lack efficiency in differentiating fungal infections such as aspergillosis, candidosis and pneumocystosis. For a more exact diagnosis of systemic fungal infections, detailed studies on the clinical symptoms are considered essential.
