非甾体类药物与过敏反应Chapter1:Introduction
Nonsteroidalanti-inflammatorydrugs(NSAIDs)areawidelyusedclassofmedicationsthatproviderelieffrompain,inflammation,andfever.Theyareextensivelyprescribedforvariousconditions,includingarthritis,headache,andmenstrualcramps.However,despitetheirefficacy,NSAIDscanalsocauseallergicreactionsinsomeindividuals.ThispaperaimstodiscusstherelationshipbetweenNSAIDsandallergicreactions,includingthemechanismsinvolvedandthemanagementofsuchreactions.
Chapter2:MechanismsofNSAID-inducedallergicreactions
1.Immunologicalmechanisms:NSAIDscaninduceallergicreactionsthroughimmune-mediatedmechanisms.Oneofthecommonlyobservedmechanismsistheformationofdrug-specificantibodies,leadingtotheactivationoftheimmunesystem.Thiscanresultinthereleaseofinflammatorymediators,suchashistamine,whichleadstoallergicsymptoms.
2.Activationofmastcells:Mastcellsplayapivotalroleinallergicreactions.NSAIDscantriggerthereleaseofmastcellmediators,includinghistamineandleukotrienes.Thisactivationcancontributetothedevelopmentofsymptomssuchashives,itching,andswelling.
3.Involvementofprostaglandins:NSAIDsinhibittheproductionofprostaglandins,whichareinvolvedintheregulationofimmuneresponses.Reducedprostaglandinlevelscanleadtoanimbalanceintheimmunesystem,makingindividualsmorepronetoallergicreactions.

2.Respiratorysymptoms:NSAID-inducedreactionscanalsoaffecttherespiratorysystem,causingsymptomssuchaswheezing,shortnessofbreath,andbronchospasm.Individualswithpre-existingasthmamaybeatahigherriskofdevelopingthesesymptoms.
3.Diagnosis:ThediagnosisofNSAID-inducedallergicreactionsinvolvesathoroughmedicalhistory,physicalexamination,andspecificallergytesting.SkinpricktestsanddrugprovocationtestsarecommonlyusedtoidentifytheculpritNSAIDresponsiblefortheallergicreaction.
