SUMMARY

Background. We assessed differences in allergic sensitization and clinical characteristics in a foreign-born population. Methods. Prospective, observational, descriptive study of patients aged > 12 years who were seen at the Department of Allergy, La Paz Hospital (Madrid, Spain), between January 2017 and December 2018. Patients were classified by geographical origin and ethnicity. Results. We included 150 patients (110 female) with a mean age of 38.38 years. Mean time to onset of respiratory symptoms after immigration was 8.47 years. Significant differences were observed between ethnic groups (p = 0.007). The most frequent sensitization was to grass pollen (75.2%), which was more common in South American patients (p = 0.005). We found that 59% of patients were sensitized to Cupressus and Olea pollen (higher in Asian patients, p = 0.032 and p = 0.049). Conclusions. Allergic sensitization in the foreign-born population was similar to that of the autochthonous population although differences between the groups were identified.
