BACKGROUND: Although standard skin prick test (SPT) panels are crucial for routine investigation of sensitization in daily clinical practice, it has limitations in terms of missing allergens.
OBJECTIVE: To find out sensitization rates (SR)s to additional panel of allergens and their relative contributions in allergic diseases.
METHODS: SPTs with a battery of aeroallergens [tree pollen (A.glutinosa, C.arizonica, J.communis, T.platyphyllos, R.pseudoacacia), weed pollen (R.acetosa, U.dioica, A.artemisifolia), smut mix, yeast mix, storage mites (SM) (B.tropicalis, L.destructor, T.putrescentiae, A.siro), mouse and budgerigar epithelia], were performed to 318 participants (6-18 years) who were previously identified to be sensitized to at least one of the aeroallergens found in standard battery.
RESULTS: Forty percent of participants were sensitized to at least one additional aerollergen. Three most frequent sensitizations were to B.tropicalis (11.3%), R.pseudoacacia (9.7%) and L.destructor (8.2%). SR for tree pollen increased from 6.9% to 19.8%, for mites increased from 26.3% to 31.6% and for moulds increased from 5.3% to 9.4% with addition of respective group of other allergens to battery. Furthermore, higher rates for additional tree pollen sensitization was found among patients with "only AR" (21%) compared to patients with "only asthma" (4.6%, p =0.006), contrarily higher rates for SM sensitization was found among patients with "only asthma" (20%) compared to patients with "only AR" (3.2%, p =0.003) CONCLUSIONS: Though some of sensitizations may occur due to cross-reactivity, almost 40% of sensitized children were also co-sensitized to the additional allergens tested. Physicians should consider further steps when a negative or inconsistent result is achieved through a standard skin test panel.
