“…In addition, to elucidate mechanisms of SIT, we tested BGP-sensitive patients before and after standard immunotherapy using a tailored depot preparation containing 50% BGP and 50% 7-grass mix. This preparation was used since there is minimal cross-reactivity between pollen of grasses of the Pooideae subfamily and BGP [11, 12, 13, 14]. Therefore, the standard 7-grass mix extract (rye, cocksfoot, bent, Kentucky blue, sweet vernal, timothy and meadow fescue), frequently used for immunotherapy of grass pollen allergy, is unlikely to relieve symptoms due to BGP sensitisation.…”
