Fig 1 Fungal recovery from sinus lavage is more likely in the context of TH2-associated airway disease. A-C, Percentage of patients yielding positive fungal cultures from sinus lavage comparing control patients to patients with CRSsNPs, patients with CRSwNPs, and patients with AFRS (Fig 1, A); control patients and nonasthmatic patients to patients with asthma (Fig 1, B); and patients with non–TH2-associated disease to patients with TH2-associated disease (Fig 1, C). *P < .05, **P < .01, and ***P < D and E, Representative Sabouraud's plate fungal cultures of sinus lavage fluid from 2 subjects. F, Photomicrograph of unstained sinus lavage mucus from a representative patient with AFRS showing extensive hyphal network (400×). §Control is a subset of all patients without asthma.

Fig 2 Fungus-specific IL-4 and IgE responses predict TH2-associated disease. Subjects with and without TH2-associated disease (TH2 and no TH2, respectively) were assessed for specific serum IgE (A) and IL-4 memory recall responses (B) from PBMCs against whole-cell antigens derived from the fungi A alternata, A fumigatus, and A niger, both individually and combined. For the combined analysis, the largest positive response obtained with any of the 3 fungal antigens was plotted. Values above dotted lines represent positive responses. C, ROC curve analyses for both IgE and IL-4 reactivity using optimal IgE and IL-4 cutoff values of 6 kIU/L and 50 cells/106 PBMCs, respectively. AUC, Area under the curve. *P < .05, **P < .01, and ***P < .001.

Fig 3 Fungus-specific PBMC IL-4 responses occur in the majority of patients with TH2-associated disease. A-C, PBMCs isolated from the indicated subject populations were cultured in media alone or supplemented with 5 mg of antigen derived from 9 fungi, and IL-4 secretion by ELISpot analysis was performed 24 hours later. A positive reaction to any antigen was more than 50 IL-4–secreting cells/106 PBMCs above media control. Patients with TH2-associated airway disease have either CRSwNPs or asthma or both. D, Maximal fungus-specific IL-4 ELISpot responses comparing subjects with TH2-associated and nonassociated disease. E, Distribution of the number of distinct fungi inducing positive IL-4 ELISpot responses in subjects with allergic airway disease. F, Percentage of patients with Th2–associated disease reacting to the indicated fungal allergens. **P < .01 and ***P < §Control is a subset of all patients without asthma.

Fig 4 Fungal-specific IL-4 responses are highly concordant with the species isolated. A-C, IL-4 ELISpot data were determined using antigens matched to fungi derived from the same patient and were otherwise collected as in Fig 3. *P < .05 and **P < .01. §Control is a subset of all patients without asthma.

Fig E1 Fungal-specific IgE responses to A niger, A fumigatus, or A alternata are elevated in patients with AFRS and highly concordant with the species isolated. A-C, IgE positivity data analyses based on various patient groupings. D-F, IgE ELISA data limited to patients who grew A niger, A fumigatus, or A alternata from their airways. *P < .05. §Control is a subset of all patients without asthma.
