Role of some medically important arthropods in home environment and childhood urticaria

ABSTRACT

Home environment does not only affect morbidity but also chronicity of certain disease of the reared children. Several medically important arthropods are of special concern, as well as domestic anima and pets. Fifty patients with popular urinary, compared to 50 normal controls, were tested with 5 types of mite antigens acarus siro, dermatophagoides farinae, derratophagoides, pteronyssinus, clycophagus domesticus and tyrophaus putrescentiae. The skin reaction were recorded after 1/2 hours, 24 hours and 48 hours. This study revealed that popular urticaria is prevalent in children below 7 years. Both sexes were equally affected. Family history has no significant role in the disease. There was a significant relation between pets and the disease. Mites play an important role in the aetiology of popular urticaria. The most responsible mites are dermatophagiods farinae and yrophagus putrescentiae. Dermatophagoides pternoyssinus and glycophagus domesticus had no statistical significant relation to popular urticaria as tested by mite antigen skin reactions. However, there were actually more positive reaction in patients with popular utricaria than in the control groups. It is questionably advised that desensitization may be of real health for patients with popular urticaria which can be administered at an early phase of the disease. Also, environmerltal control of mites will be very helpful in suppressing and minimizing the attacks
