PURPOSE OF REVIEW Sublingual immunotherapy is becoming a routine treatment for
respiratory allergy in several countries and it has been validated in
international documents. This article will review the available literature on
oral and sublingual immunotherapy, discussing the possible use of sublingual
immunotherapy in paediatric patients.RECENT FINDINGS As oral immunotherapy was
found to be poorly effective in clinical trials, its use has been discontinued.
In contrast, several controlled studies have shown the efficacy of sublingual
immunotherapy in children with allergic asthma and rhinitis, and a postmarketing
survey has confirmed its safety. Moreover, new data on the long-lasting efficacy
of this treatment and on the absence of local immunological effects have
recently been published.SUMMARY The clinical efficacy and the optimal safety
profile of sublingual immunotherapy make it a good candidate for treating
respiratory allergy in children. Some aspects, such as the dose-response
relationship and preventive effect, will be a research challenge for future
developments and better definition of indications in children.
