Respiratory symptoms
The median cat, dog, and
cockroach allergen concentrations in the fall were medium to high
in homes (0.9-1.6 mg/g) and even higher in schools (0.8-2.0 mg/g).
Increased concentrations were observed in the winter, to levels
associated with asthma symptoms in sensitized individuals
The group of children with gastrointestinal illness had statistically significantly higher cat allergen level at home (P<.05) as well
as factor score 4 (loaded positively with cat and negatively with
mouse allergen).Furthermore, it was found that the group of children with fewer
asthma symptom free days trended with higher cockroach
allergen levels in homes (P<.10) and factor score 2 (positively loaded
with cockroach and several other allergens). In addition, the group of
children with lower asthma control test score trended with higher
factor score 3 (positively loaded with ATP and dog allergen).
