Abstract

The prevalence  of allergic  diseases  such as asthma  is high in general population  and aeroallergens - are the most common  allergens that  cause air way inflammation.

The aim  of this  study  is to identification   of the most  common  aeroallergens  by skin prick  tests  and the risk factors among asthmatic  patients.

A retrospective  study were conducted  on130  patients  with Bronchial  asthma   of these patients 68(52 %)were  male and 62 (48%)were  female  . Age of patients  was between  7 to75  years with a mean  of age: 31.62 yr.

The  patients  were  referred  to  allergic  clinic  of  Tikrit  Teaching  Hospital  and  skin  prick tests(SPT)response    to  aeroallergens   were  studied  which  shows115(88%)    of patients  were  sensitized   , but15(12   %)  had  negative   SPT  (unsensitized),  among  the   sensitized  patients17(13  %)  were monosensitized  against one allergen,39  (30%)  were sensitized  against 2 allergens   and 59(45%)  sensitized against 3 allergens.

In  regard  to  pollen   aeroallergens(61%)    were  considered   the  most  common   allergen   and  among pollen the bermuda (36%) had the highest rate of sensitization.   Also this study  shows the prevalence  of Asthma was higher  in a third decade  age  group while  less  in sixth decade  and according to the occupation,  positive  SPT  were higher  in house wives patient(38%)  .
