CASQUERO C, José et al. Frecuencia de aspergiloma en pacientes con antecedentes de Tuberculosis, Hemoptisis, radiografía de tórax anormal y baciloscopía negativa. Rev. perú. med. exp. salud publica [online]. 2006, vol.23, n.2, pp.104-109. ISSN 1726-4634.

Objective: To determine the frequency of aspergilloma in patients with history of cured pulmonary tuberculosis, hemoptysis, abnormal chest X-ray films, and negative sputum smears for acid-fast bacilli. Materials and methods: 28 patients were enrolled between December 2002 and September 2004 in Hipolito Unanue National Hospital in Lima and Belen Hospital in Trujillo. Patients from Belen Hospital had three serial and consecutive sputum samples taken, while those patients from Hipolito Unanue Hospital who underwent thoracic surgery had a portion of the surgical specimen collected. Both biological samples were cultured in Sabouraud dextrose agar - 0,05% chloramphenicol, and they were incubated at room temperature and at 37° C for 15 days. All patients had a 5-mL blood sample taken in order to perform immunodifusion tests for Aspergillus sp. Results: The frequency of aspergilloma was 43%) (12/28). Aspergillus fumigatus was identified in cultures in five cases, Aspergillus sp. was identified in two cases, A. niger in one, A. flavus in one, and in two cases reported as positive for serological tests the fungus could not be isolated. In the two patients in whom A. niger was identified, no presence of antibodies against Aspergillus sp. was detected. In Belen Hospital the frequency of aspergilloma was 39% (7/18), and in Hipolito Unanue Hospital it was 50% (5/10). Conclusions: Aspergilloma frequency in 28 patients studied in both hospitals was 43%, and the main etiological agent was A. fumigatus.
