- BACKGROUND: We have recently reported that sensitisation to food allergens and sensitisation to airborne allergens had independent associations with increased fraction of exhaled nitric oxide (FeNO) and blood eosinophils in middle-aged adults and in young subjects with asthma.OBJECTIVE: To investigate the relation between IgE sensitisation and several type 2 inflammation biomarkers in adult asthmatics.METHODS: FeNO, urinary eosinophil-derived neurotoxin (U-EDN), serum eosinophil cationic protein (S-ECP) and periostin were measured in 396 asthmatics, aged 17-76 years, from the Swedish GA2LEN study. Sensitisation to airborne allergens was examined with skin prick tests (≥3 mm wheal) and sensitisation to food allergens with measurement of specific IgE (≥0.35kU/L).RESULTS: Asthmatics sensitised to food allergens had higher FeNO, 22.3 ppb (18.6, 26.7) vs. 16.1 ppb (14.2, 18.2) (p=0.005), S-ECP, 17.7 mg/L (14.8, 21.1) vs. 12.8 mg/L (10.9, 14.9) (p=0.01), and periostin, 73.7 (67.5, 80.3) ng/mL vs. 59.9 (55.8, 64.2) ng/mL (p=0.003), than non-sensitised subjects. Periostin levels in this group were also significantly higher than in the group sensitised only to airborne allergens (p=0.01). Sensitisation to food allergens related independently to FeNO (p=0.02), S-ECP (p=0.006) and periostin (p=0.004), whereas sensitisation only to airborne allergens related only to FeNO (p=0.02) after adjustments for age, sex, height, weight and smoking history. FeNO correlated weakly with S-ECP (r=0.17, p<0.001), periostin (r=0.19, p<0.001) and U-EDN (0.16, p<0.001). S-ECP also correlated weakly with U-EDN (r=0.12, p=0.02). None of the correlations between the remaining pairs of markers of type 2 inflammation were significant.CONCLUSIONS & CLINICAL RELEVANCE: Sensitisation to food allergens related to several local and systemic type 2 inflammation markers, such as FeNO, S-ECP and periostin. Assessing the profile of allergic sensitisation, including to food allergens, might improve the understanding and interpretation of inflammatory markers and potentially improve asthma management.
