• #1 Prevention of Drug Hypersensitivity Reactions: Prescreening and Premedication – PubMed

  https://pubmed.ncbi.nlm.nih.gov/34366094/

  Drug hypersensitivity reactions (DHR) are heterogeneous in their pathomechanisms, clinical presentation, severity, and outcomes. The key to prevention from further exposure to the culprit drugs involves correct identification of the putative drug through a combination of in vitro and/or in vivo tests, accurate drug allergy labeling and reporting, and electronic decision support systems within electronic medical records to prevent future accidental prescribing. Prescreening and premedication, the focus of this review, may be a useful adjunct to preventive measures in certain situations. […] After an index immediate drug hypersensitivity reaction, prescreening may be useful in perioperative anaphylaxis, and iodinated (ICM) and gadolinium-based contrast media (GCM) where the culprit and potential alternative agents are skin tested.

  Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions with varying mechanisms and clinical presentations. […] Therefore, referral to an allergist experienced in the identification, diagnosis and management of drug allergy is recommended if a drug-induced allergic reaction is suspected. […] The most effective strategy for the management of drug allergy is avoidance or discontinuation of the offending drug. […] When available, alternative medications with unrelated chemical structures should be substituted. […] Cross-reactivity among drugs should be taken into consideration when choosing alternative agents. […] If a particular drug to which the patient is allergic is indicated and there is no suitable alternative, induction of drug tolerance procedures may be considered to induce temporary tolerance to the drug.

  A drug allergy, then, is one type of unpredictable (Type B) ADR, and it accounts for approximately 5 to 10 percent of all ADRs. To put it another way, a drug allergy is an abnormal immune-system reaction to a drug, be it prescription, over the counter, or herbal. Drug-allergy reactions can happen the first time the medication is taken or only after repeated exposure. […] Your healthcare provider may recommend a plan that includes the following. Exposure Reduction: Avoid or discontinue the offending drug. Substitute alternative medications with unrelated chemical structures if possible. However, consider any cross-reactivity when choosing substitutions. Inform healthcare workers (including specialists and dentists) of your allergy and ensure its clearly noted in your medical records. Ask your doctor for a list of drugs (including over-the-counter medications) to avoid.

  https://www.bsaci.org/resources/allergy-management/drug-allergy/

  The investigation of drug allergy relies heavily on a detailed clinical history which must include a description of the rash, the onset of symptoms and the number of doses of each drug taken before the reaction starts. Therefore, documentation of an acute drug-allergic reaction is key to accurate identification of the culprit. The NICE drug allergy guideline (CG183 2014) provides guidance on documentation and recommends that the patient receives written communication detailing the nature of their drug allergy and a list of drugs to avoid. It is essential that all primary and secondary care organisations incorporate a template onto their electronic patient record systems in order to fulfil the requirements for documentation and communication of drug allergy.

  The implementation of DAAS has many benefits. Healthcare alert systems improve quality and patient safety by preventing errors and adverse events. […] Despite these advantages, however, the use of DAAS may present challenges. […] The usefulness of DAAS lies mainly on their capacity to function as automated security tools which guarantee patient safety, while partially reducing the burden of monitorization from individuals. […] The aspects mentioned make the usefulness of DAAS seem intuitive and logical. […] One of the main issues interrupting the usefulness of DAAS is the excess of incorrect reports, which leads doctors to ignore the alerts. […] Different proposals have been described with the aim of reducing the number of overrides. […] Like any initiative involving patient safety, DAAS are tools whose function depends on the organised use of data.

• #22 Desensitization for the prevention of drug hypersensitivity reactions

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8925949/

  Drug desensitization is the temporary induction of tolerance to a sensitized drug by administering slow increments of the drug, starting from a very small amount to a full therapeutic dose. It can be used as a therapeutic strategy for patients with drug hypersensitivity when no comparable alternatives are available. Desensitization has been recommended for immunoglobulin E (IgE)-mediated immediate hypersensitivity; however, its indications have recently been expanded to include non-IgE-mediated, non-immunological, or delayed T cell-mediated reactions. […] Once DHR is diagnosed, the culprit drug should be avoided and replaced with alternatives. However, alternative options are often less effective, more toxic, and sometimes unavailable. In this situation, drug desensitization allows the reintroduction of culprit drugs to highly sensitized patients in need of first-line therapies. Desensitization is performed by administration of extremely low doses of the culprit drug, below the threshold for induction of a hypersensitivity reaction, followed by a gradual increase in the dose at fixed time intervals, to allow adaptation to a given amount or concentration; this leads to the development of temporary tolerance to the drug, eventually at its full therapeutic dose.

  The mainstay of treatment for drug allergy is avoidance of the offending drug. When available, alternative medications with unrelated chemical structures should be substituted. Cross-reactivity among drugs should be taken into consideration when choosing alternative medications. If a particular drug to which the patient is allergic is indicated and there is no suitable alternative, induction of drug tolerance procedures may be considered to induce temporary tolerance to the drug.

• #24 Desensitization for the prevention of drug hypersensitivity reactions

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8925949/

  Before performing drug desensitization, the diagnosis should be confirmed by thorough history taking and testing. Desensitization should be considered when no alternative options are available or the culprit drug has far superior efficacy, i.e., the benefits of the culprit drug outweigh the risk. It should be carefully applied in patients with significant risk factors for fatal BTRs, such as those with a history of severe hypersensitivity reactions, like anaphylaxis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, those with cardiovascular or respiratory diseases, and those using beta-blockers. […] The appropriate protocol should be selected based on the concentration, dosage, dosing interval, and route of administration (oral, intravenous, intramuscular, or subcutaneous). Oral and intravenous protocols are widely used because intramuscular and subcutaneous protocols involve frequent injections.

  The World Health Organization defines an adverse drug reaction (ADR) as a response to a drug which is noxious and unintended, and which occurs at doses usually used in man for the prophylaxis, diagnosis, or therapy of disease, or for the modification of physiological function. […] In patients with suspected drug allergies, a thorough history is essential and can help guide further evaluation, workup, and management. […] To confirm the diagnosis of drug allergy, discontinuation of the suspected culprit medication with resolution of the allergic reaction helps to support the hypothesis. […] Induction of drug tolerance or drug desensitization allows the patient to take a medication temporarily in a safe manner but does not modify the patients underlying immune response to the drug. […] Given the risk of anaphylaxis with introducing a suspected allergen, desensitization should be performed in a hospital (usually an intensive care unit) with appropriate resuscitation equipment available and in consultation with an allergy-immunology specialist.

• #26 Desensitization for the prevention of drug hypersensitivity reactions

  https://pmc.ncbi.nlm.nih.gov/articles/PMC8925949/

  BTRs should be promptly managed depending on their severity. For mild to moderate BTR, desensitization should be stopped, and appropriate medication, such as antihistamines and/or glucocorticoids, should be administered to the patient. After the symptoms have resolved, desensitization can be resumed at the same step or the step prior to that in which BTR occurred, and most patients succeed in completing the protocol without further BTRs. […] Immunological tolerance can be maintained with continued administration of the drug. For drugs that are administered intermittently, such as chemotherapeutic agents, desensitization should be performed at every cycle, as the tolerance fades during the drug-free interval.

  Xolair (omalizumab) injection for immunoglobulin E-mediated food allergy in certain adults and children 1 year or older for the reduction of allergic reactions (Type I), including reducing the risk of anaphylaxis, that may occur with accidental exposure to one or more foods. […] Xolair is intended for repeated use to reduce the risk of allergic reactions and is not approved for the immediate emergency treatment of allergic reactions, including anaphylaxis. […] While it will not eliminate food allergies or allow patients to consume food allergens freely, its repeated use will help reduce the health impact if accidental exposure occurs. […] Current treatment requires strict avoidance of the food(s) the patient is allergic to, and prompt administration of epinephrine to treat anaphylaxis should accidental exposures occur. […] As a result, continuation of strict allergen avoidance is still necessary, despite treatment with Xolair.

  Senior study author Dr. Sharon Chinthrajah, an associate professor of medicine and pediatrics at and acting director of the Sean Parker Center for Allergy and Asthma Research at Stanford University, noted that Xolair is not a cure, and patients still need to avoid the foods they are allergic to. But it is a tremendous layer of safety, she said. […] This therapy offers injections and offers an umbrella, a safety protection, to go out and live your lives normally to not be as afraid of accidental exposures and everyday living, Chinthrajah said. […] The drugs ability to do this is finite, however, Gupta said. For that reason, the drug is meant to prevent reactions to small accidental exposures to allergic foods rather than allowing a person to indulge in them.

  Patients and family members should be educated on the generic names of the drugs they are allergic to and other potentially cross-reacting drugs. In addition, the patient should be given a Medic Alert card or bracelet to avoid future accidental prescription/dispensing of any drugs to which he or she is allergic. Through the use of electronic medical records, pharmacovigilance in the form of adverse drug reaction reporting to drug regulatory agencies and accurate labelling to avoid future reactions should be constantly emphasized.
