Background and Objective: The allergens in the closed environments and at home because of the constant contact can cause severe and permanent allergies. In this study, the frequency and the clinical findings were evaluated in patients who were allergic to domestic allergens.
Materials and Methods: In this study, all the patients with a positive skin test to at least one allergy were extracted, and during the face-to-face examination or phone call, the clinical findings and common problems with respiratory, skin or other disorders were evaluated. Then, the relationship between the above findings and the skin test was analyzed by the SPSS software.
Results: From 502 patients with a positive skin test, 406 individuals were included in the study. 195 people (48%) inside the house had a positive skin test to domestic allergens. In these patients 97 (23.9%) were allergic to mite, 82 (20.2%) to molds, 78 (19.2%) to beetles, 51 (12.6%) to domestic birds’ feather and 31 (7.6%) were allergic to cat allergens. In comparison, the dyspnea was significantly higher in the mold-sensitive patients (P = 0.01). The eyes involvement was significantly less in patients sensitive to mite and mold (P = 0.01 and P =0.02 respectively).
Conclusion: In this study, the skin test response to indoor allergens was relatively high. Therefore, attention to these allergens and training to avoid the occurrence of these factors and controlling them at home is recommended.
