Allergy - Late-phase response

An allergy or Type I hypersensitivity is an immune malfunction whereby a person's body is hypersensitised to react immunologically to typically nonimmunogenic substances. When a person is hypersensitised, these substances are known as allergens. The word allergy derives from the Greek words allos meaning "other" and ergon meaning "reaction" or "reactivity". Type I hypersensitivity is characterised by excessive activation of mast cells by immunoglobulin E resulting in a systemic inflammatory response that can resul ...

There are limited mainstream medical treatments for allergies. Probably the most important factor in rehabilitation is the removal of sources of allergens from the home environment, and avoiding environments in which contact with allergens is likely. The trouble with them is that they have not all been proven. Therefore it could be seen as a placebo; however, it has helped people. See also:

There are limited mainstream medical treatments for allergies, probably the most important factor in rehabilitation is the removal of sources of allergens from the home environment, and avoiding environments in which contact with allergens is likely. Allergy - Immunotherapy. Hyposensitization is a form of immunotherapy where the patient is gradually vaccinated against progressively larger doses of the allergen in question. This can either reduce the severity or eliminate hypersensitivity altogether. It rel ...

There has been a notable increase in the commonness of allergies in the past decades, and there are multiple hypotheses explaining this phenomenon. This is in part because we know what they are, in contrast to earlier humans who would think that it is a non-important illness. Allergy - The hygiene hypothesis. One theory that has been gaining strength is the "hygiene hypothesis". This theory maintains that since children in more affluent countries are leading a cleaner and cleaner life (less exposure to dir ...

Allergy - Genetic Basis. There is much evidence to support the genetic basis of allergy, as allergic parents are more likely to have allergic children, and their allergies are likely to be stronger than those from non-allergic parents. However some allergies are not consistent along genealogies with parents being allergic to peanuts, but having children allergic to ragweed, or siblings not sharing the same allergens. Ethnicity has also been shown to play a role in some allergies. Interestingly, in r ...

Allergy is characterised by a local or systemic inflammatory response to allergens. Local symptoms are: Nose: swelling of the nasal mucosa (allergic rhinitis) The distinctive behavior known as nasal salute, also known as allergy salute, is the habit of wiping of the nose in an upward direction due to itching. Eyes: redness and itching of the conjunctiva (allergic conjunctivitis) Airways: bronchoconstriction, wheezing and dyspnoea, sometimes outright attacks of asthma Skin: various rashes, such as eczema, hi ...

There are several methods for the diagnosis and assessment of allergies. Allergy - Skin test. The typical and most simple method of diagnosis and monitoring of Type I Hypersensitivity is by skin testing, also known as prick testing, due to the series of pricks made into the patient's skin. Small amounts of suspected allergens and/or their extracts (pollen, grass, mite proteins, peanut extract, etc.) are introduced to sites on the skin marked with pen or dye (the ink/dye should be carefully selected, lest i ...

All hypersensitivities result from an aberration somewhere in the normal immune process. The exact cause of such malfunctions is not always apparent, however, and several arguments from genetic-basis, environmental-basis and intermediate proponents exist with varying validity and acceptance. Allergy - Acute response. The difference between a type I hypersensitivity reaction against an allergen to the normal humoral response against a foreign body is that plasma cells secrete IgE as opposed to either IgM (a ...
