BACKGROUND AND OBJETIVE: To determine clinical variables to distinguish invasive pulmonary aspergillosis (IPA) from colonization in patients with chronic pneumopathies with positive culture of Aspergillus spp. in respiratory samples. PATIENTS AND METHODS: Retrospective cohort study including patients with respiratory isolations of Aspergillus spp. during a period of 10 years. IPA was evaluated according to the Bulpa criteria. Clinical variables were collected and a multiple logistic regression analysis was carried out. RESULTS: Eighty-three patients with isolation of Aspergillus spp. from respiratory samples were included; 68.7% (n=57) of the patients had chronic obstructive pulmonary disease, 18% (n=15) pulmonary fibrosis and 13.3% (n=11) bronchial asthma. Twenty-two patients (26.6%) had IPA. The use of fluconazole (OR 4.49; CI 95% 1.5-13.4; P=.007), severe respiratory failure (OR 4.64; CI 95% 1.46-14.72; P=.009) and hospitalization time (OR 1.05; CI 95% 1.01-1.1; P=.006) were associated with IPA. CONCLUSIONS: Prior use of fluconazole, severe respiratory failure and hospitalization time are associated with IPA in patients with chronic pneumopathies with respiratory isolation of Aspergillus spp.
