Abstract

Introduction: Aspergillosis is an opportunistic mycosis with significant impact on immunocompromised patients; available data in Paraguay are scarce.

Objectives: To characterize patients diagnosed with aspergillosis whose samples were sent to the Mycology section of the Central Public Health Laboratory during the period 2000-2019.

Methods: A descriptive, retrospective study of clinical records from patients with positive specimens for Aspergillus genus.

Results: Fifty-four patients were diagnosed with aspergillosis: Otomycosis 21 (38.9%), chronic pulmonary aspergillosis 17 (31.5%), acute and chronic sinusitis 5 (9.2%), invasive aspergillosis 4 (7.4%), onychomycosis 3 (5.6%), allergic bronchopulmonary aspergillosis 2 (3.7%), and keratitis 2 (3.7%). There were 56 isolates: Aspergillus section Fumigati 26 (46.4%), A. section Flavi 15 (26.8%), A. section Nigri 13 (23.2%), A. section Terrei 1 (1.8%), and Aspergillus glaucus 1 (1.8%). Microbiological diagnostic methods included fresh examination, staining, culture, and serology testing.

Conclusions: Multiple cases of aspergillosis were reported over a 20-year period. Otomycosis, predominantly in adults, was the most prevalent form of aspergillosis. In chronic rhinopulmonary forms, tuberculosis, tumors, chronic obstructive disease, cystic fibrosis, and asthma were the predisposing factors. Invasive aspergillosis was predominantly observed in pediatric patients, where autoimmune diseases and leukemias were the primary risk factors. Aspergillus section Fumigati was the predominant isolate, followed by Aspergillus section Flavi and Aspergillus section Nigri.
