Abstract

34.2%), Cat (51.7%), Dog (50.8%) and cockroaches, Blatella germanica (48.3 8%) and Periplaneta Americana (53.3%). Overall, multiple sensitization (sensitization to >4 allergens) was significantly associated with increasing level of asthma severity (p<0.001). However, that association disappeared after adjustment for potential confounders like age, sex, exposure to smoking, pet and having family history of asthma or allergic rhinitis. It remained statistically significant only for the patients sensitized to HDM as the relationship was not modified by con founders. Moreover, mean SPT wheal size was not significantly associated with severity of asthma for all allergens tested. Conclusions HDM was the most common sensitizing aeroallergen. Although children with moderate to severe asthma had significantly higher proportion of SPT positive, this study could not establish any relationship between degree of wheal size and severity of asthma. Therefore, the association between degree of sensitivity to indoor allergen and childhood asthma severity is still uncertain.
