Abstract
BACKGROUND: Allergic bronchopulmonary mycosis (ABPM) occurs with fungi, other than Aspergillus fumigatus. However, the clinical characteristics of ABPM caused by non-Aspergillus species are unspecified. METHODS: We retrospectively reviewed all patients with ABPM who visited to our hospital between April 2005 and December 2020. The causative fungi and clinical characteristics were analyzed. Patients were divided into the Aspergillus group and the non-Aspergillus group. RESULTS: Fourteen patients and five patients were included in the Aspergillus group and the non-Aspergillus group, respectively. Compared to the Aspergillus group, the non-Aspergillus group had a significantly low serum immunoglobulin E level and low forced vital capacity. In addition, the non-Aspergillus group had a lower rate of the requirement for oral corticosteroid treatment and a low frequency of recurrence. CONCLUSION: Patients with non-Aspergillus ABPM had lower type 2 inflammation than did patients with allergic bronchopulmonary aspergillosis.
