Abstract:
Objective To study the effect of specific immunotherapy (SIT) with purified humulus pollen allergens for asthma patients. Methods The humulus pollen allergens were purified partially by gelatin filtration. A double-blinded study was carried out. Eight-six patients with seasonal humulus pollen allergic asthma were divided randomly into two groups: observation group (group A) and control group (group B), which were administered SIT with purified or crude humulus pollen allergens, respectively, before the allergic season for half a year. The clinical effect and side effects were observed. The laboratory observation norms included T lymphocyte subpopulation, the wheals’diameter of IT, the average index of HBDT and the specific IgE before and after SIT . Results The general effect of SIT with purified allergens in group A was 90.7% (39/43), and that with crude allergens in group B was 79.1% (34/43) (P
