[Enhancement of nonsteroidal, anti-inflammatory drugs and preventive effect of antihistamines and disodium cromoglycate on wheat allergy].

Background: Aspirin has been known to be an enhancer to wheat allergy, including wheat-dependent, exercise-induced anaphylaxis.

Objective: To investigate whether nonsteroidal, anti-inflammatory drugs (NSAIDs) other than aspirin would enhance allergic reactions after wheat ingestion and whether antihistamines and disodium cromoglycate would prevent these reactions.

Methods: Seven cases, whose reactions after wheat ingestion were enhanced by aspirin on challenge tests, were enrolled.

Hyperproduction of IFN-gamma by CpG oligodeoxynucleotide-induced exacerbation of atopic dermatitis-like skin lesion in some NC/Nga mice.

Under conventional conditions, NC/Nga mice spontaneously develop an atopic dermatitis (AD)-like skin lesion accompanied by immunoglobulin E (IgE) hyperproduction and the expression of T helper 2 (Th2) cytokines. CpG DNA activates a strong interferon-gamma (IFN-gamma)-dominated T helper 1 (Th1) response, while inhibiting Th2-dependent allergies. In this study, we examined whether CpG oligodeoxynucleotide (ODN) could prevent the development of the skin lesions in NC/Nga mice.
