Effect of rush immunotherapy (RIT) on Hymenoptera allergy
1999
: In our country approximately forty people die every year from anaphylaxis caused by hymenoptera stings. Between 1988 and 1996, 48 patients, who had experienced a systemic reaction to hymenoptera sting and were proved to have specific IgE antibodies to wasp, yellow or both (RAST score > or = 2), received rush immunotherapy (RIT) using venom extracts in our hospital. Fifteen patients had re-sting after RIT. Fourteen out of the 15 patients showed only local reaction to the hymenoptera re-sting and one patient had mild generalized symptoms. Although one patient showed mild generalized uriticaria during RIT, no adverse reaction occurred during and after RIT in the other subjects. Follow-up studies on the titers of serum total IgE antibodies and hymenoptera specific IgE and IgG4 antibodies revealed that total and specific IgE antibodies transiently increased one month after RIT and returned to their baseline values by 6 months after RIT, while specific IgG4 antibodies continued to gradually increase up to al least 3 years after RIT. These results demonstrates that RIT is effective in prevention of a systemic reaction to hymenoptera re-sting and an increase in the titer of hymenoptera specific IgG4 antibodies may at least partly explain the efficacy of RIT.
