type i hypersensitivity การใช้

• The allergic reaction is a Type I hypersensitivity reaction.
• IgE is commonly involved in type I hypersensitivity, which manifests in the most common allergic diseases.
• In atopic individuals, non-parasitic antigens stimulate inappropriate IgE production, leading to type I hypersensitivity.
• It is not a true drug allergy, because allergies are type I hypersensitivity reactions, but repeated exposure to the offending agent can result in an anaphylactic reaction.
• With this new classification, the word " allergy " was restricted to type I hypersensitivities ( also called immediate hypersensitivity ), which are characterized as rapidly developing reactions.
• The drug itself can be targeted by the immune system, e . g . by IgE in a Type I hypersensitivity reaction to penicillin, rarely leading to anaphylaxis.
• A 2001 study at University of California at Davis showed improvements in multiple aspects of health in 25 individuals with a documented history of type I hypersensitivity to house dust.
• Although overlapping in many cases, hypersensitivity pneumonitis may be distinguished from occupational asthma in that it is not restricted to only occupational exposure, and that asthma generally is classified as a type I hypersensitivity.
• Foods that cause urticaria ( hives ) or anaphylaxis ( such as peanuts ) cause a type I hypersensitivity reaction whereby the part of the food molecule is directly recognized by cells close to the skin, called mast cells.
• IgE also has an essential role in type I hypersensitivity, which manifests in various allergic diseases, such as allergic asthma, most types of sinusitis, allergic rhinitis, food allergies, and specific types of chronic urticaria and atopic dermatitis.
• However, although overlapping in many cases, hypersensitivity pneumonitis may be distinguished from occupational asthma in that it isn't restricted to only occupational exposure, and involves type III hypersensitivity and type IV hypersensitivity rather than the type I hypersensitivity of asthma.
• Type I hypersensitivity reactions may also be involved, particularly to rosewood and ebony in the chinrest and tailpiece, as well as to varnish of the instrument body when chinrests are not used and to rosin deposits on the instrument and on chin cloths.
