Doi10.23822/EurAnnACI.1764-1489.178SummaryObjectives. To describe the prevalence of allergic sensitization to Storage Dust Mites (SDM), access whether the place of living and occupational exposure were determinants for SDM sensitization and study association between
Lepidoglyphus destructor and other SDM sensitization.
Methods. Prospective analysis of patients evaluated for suspected allergic rhinitis and/or asthma that performed Skin Prick Tests (SPT) to SDM between January and December 2018 in our Department.
Results. Two hundred consecutive patients were evaluated for rhinitis and/or asthma in our outpatient consultation: 123 (61.5%) presented positivity for at least one SDM, 68.3% were female and the mean age was 33.1 ± 12.12.
Lepidoglyphus destructor (69.9%) was the most prevalent, followed by
Tyrophagus putrescentiae (50.4%),
Blomia tropicalis and
Glycyphagus domesticus (48.8%) and
Acarus siro (24.4%). Living in a rural place was not associated with a higher prevalence of sensitization to SDM, except for
Acarus siro (p = 0.032), and working in a place with storage areas was not associated with sensitization to any of SDM. Sensitization to
Lepidoglyphus destructor was associated with sensitization to
Blomia tropicalis,
Glycyphagus domesticus and
Tyrophagus putrescentiae (p less than 0.005), but not with
Acarus siro. Conclusions. Our study suggests that our population, independently of their occupational exposure and place of residency, are sensitized to SDM and that evaluation of sensitization to SDM should be considered as standard practice.
