Oral tolerance is a physiological immune mechanism, which controls the outcome of deleterious hypersensitivity reactions to environmental antigens absorbed through the gastrointestinal tract, and maintains homeostasis. Using a mouse model of oral tolerance of delayed type hypersensitivity to contact allergens, i.e. haptens, we have examined the mechanisms involved in the induction of oral toler...
Although formaldehyde is well known to cause type 4 hypersensitivity, immunoglobulin E (IgE)-mediated hypersensitivity to formaldehyde is rare. Here, we report a case of recurrent generalized urticaria after endodontic treatment using a para-formaldehyde (PFA)-containing root canal sealant and present a review of previous studies describing cases of immediate hypersensitivity reactions to forma...
antigens can also be applied on to the kin surface and skin prick testing (SPT) can be performed. Common allergens Intradermal tests are widely used to support the diagnosis of that are tested in skin prick tes are food, fungi, epthelia, dermatological and nondermatological diseases. They are pollens and mites. Intradermal tests can be done for similar mainly indicated for the detection of imme...
BACKGROUND The liver is the most commonly involved internal organ in drug-induced systemic hypersensitivity. However, data obtained from these patients have yet to be analyzed in depth with respect to liver injury. METHODS The medical records of 136 patients who developed delayed-type drug hypersensitivity were reviewed at a tertiary referral hospital. Culprit drugs, the pattern and degree of...
Clopidogrel is a new antiplatelet prescribed for the secondary prevention of atherosclerotic events. The literature shows that the clinical manifestations of clopidogrel hypersensitivity include urticaria1, skin rash2-4, and angioedema5. The precise immunological mechanism underlying clopidogrel hypersensitivity has not been established. We describe two cases of hypersensitivity reaction due to...
