Section 4. Colombian consensus on the diagnosis and treatment of chronic, saprophytic and/or allergic syndromes associated with Aspergillus spp. in adult and pediatric patients*

Despite the ubiquity of Aspergillus species, and the fact that a person may inhale hundreds of conidia daily, only a small proportion of patients develop an infectious disease. Aspergillus spp. can cause a wide spectrum of diseases, depending on the patient’s underlying immune function; these range from an allergic syndrome, (which does not represent a true infection), a hypersensitivity reaction (ABPA), a chronic process (CPA) or invasive aspergillosis (IA). All diseases associated with Aspergillus spp. have the potential to be misdiagnosed because symptoms and/or clinical findings overlap with each other, or with other non-fungal conditions. Greater clinical recognition of the different pulmonary syndromes is needed to identify those patients who could benefit from an appropriate therapeutic approach. Multidisciplinary management is required, where the role of antifungal therapy is only established for symptomatic and/or progressive disease management, taking into account the potential for azole resistance, which adds to the complexity of treatment and, in some cases, limits therapeutic options.
