What causes paclitaxel hypersensitivity?

What causes paclitaxel hypersensitivity?

The aetiology of paclitaxel-associated HSR is multifactorial and several mechanisms have been postulated: (A) an IgE-mediated mast-cell degranulation induced by paclitaxel (Weiss et al, 1990) or Cremophor EL (Dye and Watkins, 1980; Weiss and Baker, 1987); (B) a non-IgE-mediated idiosyncratic mast-cell degranulation by …

How common is allergic reaction to paclitaxel?

Approximately 45% of patients treated with paclitaxel experience minor hypersensitivity reactions, and 2% of the patients have fatal reactions mostly within the first 2 courses of drug administration despite the use of premedication.

What is a delayed drug reaction?

The most common immune response to a drug is due to the expansion of T cells, a type of white blood cell that recognize the drug as foreign. These T cells orchestrate a delayed immune response that most often affects the skin, causing itchy rashes, and occurs days to weeks after exposure to the drug.

How do you treat a delayed reaction?

Topical corticosteroid preparations can be applied as needed. On rare occasions, the reaction to a delayed hypersensitivity skin test may be extreme and result in axillary lymphadenopathy and fever. Such reactions are self-limited and may be treated with an antipyretic medication such as aspirin or ibuprofen.

How do you manage a Taxol reaction?

When encountering a hypersensitivity reaction to paclitaxel, interrupt the infusion and administer protocol medicines—corticosteroids, diphenhydramine, and albuterol, she said. If the symptoms resolve, the infusion can then be restarted at a lower rate and titrated up.

Why do patients react to Taxol?

Taxol is an irritant. An irritant is a chemical that can cause inflammation of the vein through which it is given. If the medication escapes from the vein it can cause tissue damage.

How can I minimize my Taxol side effects?

Taxol causes little nausea. But if you should experience nausea, take anti-nausea medications as prescribed by your doctor, and eat small frequent meals.

How common are delayed allergic reactions?

That delayed reaction occurred, on average, 15 hours after people were first treated. Another study found that about 15 percent of children had a second severe allergic reaction hours after their first reaction. You’re more likely to have a delayed reaction if you: have a severe peanut allergy.

Why do I get delayed reactions?

Delayed hypersensitivity is a common immune response that occurs through direct action of sensitized T cells when stimulated by contact with antigen. It is referred to as a delayed response in that it will usually require 12–24 hours at a minimum for signs of inflammation to occur locally.

Do you titrate Taxol?

– Titrating Taxol introduces the drug slowly to the body and allows for early recognition and intervention in the event of a hypersensitivity reaction. – Standardizing administration practices not only decreases reactions but increases nursing and patient confidence with infusion.

Does Taxol cause hypersensitivity reactions?

Why does docetaxel cause hypersensitivity?

The reaction to docetaxel has been attributed to its vehicle, polysorbate 80, which is also used for etoposide29. However, data have shown that the drug itself might be the cause of hypersensitivity30,31. 3.3. Evaluation and Prevention of Hypersensitivity Reactions

Does prolonging the drug infusion of Taxol reduce the risk of HSRs?

Prolonging the drug infusion appears to have somewhat reduced, but not obviated, the risk of HSRs. The cause (taxol itself or its excipient Cremophor EL; Badische Anilin und Soda-Fabrik AG [BASF], Ludwigshafen, Federal Republic of Germany) and the mechanism of these reactions to taxol are unknown.
