We first suspected allergic bronchopulmonary mycosis (ABPM) caused by Aspergillus based on published criteria [3] given that the patient exhibited i) bronchial asthma as a comorbidity; ii) an increase in eosinophils in both the serum and BAL fluid; iii) an increase in serum total IgE concentration (2,092 IU/mL); iv) positivity for specific IgE antibodies against fungi, including Aspergillus (Table 1), as well as specific IgG antibodies against Aspergillus in the serum; and v) filamentous fungi in the BAL fluid. Here, IGHE is linked to allergic bronchopulmonary aspergillosis.
