| Abstrakt: | Objective: Studying the proven and probable invasive pulmonary aspergillosis (IPA) cases of some hospitals in Shanghai to provide evidence for the improvement of IPA clinical diagnosis and therapy. Methods: Forty-nine IPA cases were retrospectively analyzed for demography data, host factors, underlying conditions, chest CT, microorganism and histopathology examination, as well as therapy and clinical outcome. Results: Of 49 subjects including 19 (38.8%) proven and 30 (61.2%) probable IPA, 3 patients (6.1%) had no host factors, 25 patients (51.0%) had IPA associated host factors and underlying conditions, while 21 patients (42.9%) had uncertain fundamental diseases. Chest CT evaluation demonstrated that radiological lesions include nodules in 29 patients, patching in 15, mass in 12, consolidation in 10, cavitation in 34, Halo sign in 19, air bronchogram in 18, crescentic sign in 6, bilateral in 33 and multifocal lesions in 38. The yielding rate of fungus culture in sputum was 26.5% (13/49), and in bronchoalveolar lavage fluid was 66.7% (10/15). Eleven of thirty-six patients (30.6%) had positive results of serum galactomannan antigen tests. Nineteen of twenty-one patients (90.5%) were proven as IPA by lung histologic examinations. Aspergillus fumigatus was the most common pathogen 81.0% (17/21). The responding rate to initial anti-fungus therapy was 50% (21/42). Conclusion: Our study suggests that in IPA patients, bilateral, multifocal and nodular lesion could be the most common radiological characteristic, while Halo and crescentic sign occur occasionally. Invasive technologies are more valuable to IPA diagnosis. |
