Evaluation of immediate vancomycin-induced hypersensitivity reaction to severe perioperative anaphylaxis.

The evaluation of vancomycin hypersensitivity reactions is challenging, as skin testing is not validated. Intradermal testing with vancomycin in human serum albumin-based sterile saline could be a new approach to the evaluation of IgE-independent hypersensitivity reactions.

Defining Optimal Basophil Passive Sensitisation Parameters.

Background: Detecting drug-specific IgE (sIgE) is crucial for diagnosing immediate drug-induced hypersensitivity reactions. Basophil activation tests serve as a method to determine the presence of drug-sIgE, highlighting the importance of optimising the assay. Optimisation involves considering multiple factors to ensure sensitisation helps detect an antigen sIgE.

Non-IgE-mediated drug-induced hypersensitivity reactions in pediatrics.

Purpose Of Review: Despite their prevalence and potential severity, non-IgE-mediated drug-induced hypersensitivity reactions (DHRs) are under-researched and poorly defined, particularly in children. Presentations range from mild cutaneous reactions to severe systemic diseases, with pathophysiological mechanisms and reliable diagnostic markers not well established. The lack of validated tests often leads to permanent drug restrictions, reliance on second-line drugs, and increased costs.

A Skin Testing Strategy for Non-IgE-Mediated Reactions Associated With Vancomycin.

Background: Vancomycin infusion reaction (VIR), reportedly mediated through Mas-Related G Protein-Coupled Receptor-X2, is the primary vancomycin-induced immediate drug reaction. Clinically, distinguishing the underlying drug-induced immediate drug reaction mechanisms is crucial for future treatment strategies, including drug restriction, re-administration, and pretreatment considerations. However, the lack of validated diagnostic tests makes this challenging, often leading to unnecessary drug restriction.

A case report and systematic literature review: insulin-induced type III hypersensitivity reaction.

Insulin-induced type III hypersensitivity reactions (HSRs) are exceedingly rare and pose complex diagnostic and management challenges. We describe a case of a 43-year-old woman with type 1 diabetes mellitus (DM), severe insulin resistance, and subcutaneous nodules at injection sites, accompanied by elevated anti-insulin IgG autoantibodies. Treatment involved therapeutic plasma exchange (TPE) and intravenous immunoglobulin (IVIg) as bridge therapy, followed by long-term immunosuppression, which reduced autoantibody levels and improved insulin tolerance.

Non-IgE-Mediated Immediate Drug-Induced Hypersensitivity Reactions.

Immediate drug-induced hypersensitivity reactions (IDHSRs) have conventionally been attributed to an immunoglobulin E (IgE)-mediated mechanism. Nevertheless, it has now been acknowledged that IDHSRs can also occur independently of IgE involvement. Non-IgE-mediated IDHSRs encompass the activation of effector cells, both mast cell-dependent and -independent and the initiation of inflammatory pathways through immunogenic and nonimmunogenic mechanisms.

Randomized Multicenter Trial for the Validation of an Easy-to-Administer Algorithm to Define Penicillin Allergy Status in Sexually Transmitted Infection Clinic Outpatients.

Background: Approximately 15% of patients in sexually transmitted infection (STI) clinics report penicillin allergies, complicating treatment for syphilis and gonorrhea. Nonetheless, >90% do not have a penicillin allergy when evaluated. We developed and validated an algorithm to define which patients reporting penicillin allergy can be safely treated at STI clinics with these drugs.

Examining cefazolin utilization and perioperative anaphylaxis in patients with and without a penicillin allergy label: A cross-sectional study.

Study Objective: To compare the occurrence of cefazolin perioperative anaphylaxis (POA) in patients with and without a penicillin allergy label (PAL) to determine whether the prevalence of cefazolin POA differs based on the presence of a PAL.

Design: Cross-sectional study.

Setting: A large U.

Pharmacogenetics to prevent hypersensitivity reactions to antiepileptic drugs: is testing performed when indicated?

Extensive scientific evidence consistently demonstrates the clinical validity and utility of HLA-B*15:02 pre-screening in averting severe cutaneous adverse reactions (SCARs), namely Stevens-Johnson syndrome and toxic epidermal necrolysis, associated with carbamazepine or oxcarbazepine usage. Current practice guidelines and drug labeling actively advocate for pharmacogenetic pre-screening before initiating these antiepileptic drugs (AED), with particular emphasis on patients of Asian descent. However, there is a potential need to strengthen compliance with these recommendations.

Use of the Electronic Health Record for Monitoring Adverse Drug Reactions.

Purpose Of Review: Adverse drug reactions (ADRs) are a significant cause of morbidity and mortality. The electronic health record (EHR) provides an opportunity to monitor ADRs, mainly through the utilization of drug allergy data and pharmacogenomics. This review article explores the current use of the EHR for ADR monitoring and highlights areas that require improvement.

Prevention of Recurrent Attacks of Hereditary Angioedema (HAE): Berotralstat and Its Oral Bioavailability.

Hereditary angioedema (HAE) is a condition characterized by episodes of cutaneous and submucosal edema. Angioedema of the extremities and abdominal attacks are the most common manifestations of the disease. It can also affect the upper airways with the potential of becoming life-threatening.

Juntos: A Model for Language Congruent Care to Better Serve Spanish-Speaking Patients with COVID-19.

Coronavirus disease 2019 (COVID-19) exacerbated pre-existing health disparities and disproportionately affected the Latino community. Clinicians identified communication barriers as a major challenge in care for COVID-19 Latino patients with limited English proficiency (LEP). To address these challenges, Juntos (Together) consult service was established to promote language-congruent care with cultural sensitivity, identify barriers to safe discharge, and facilitate referral to appropriate resources.

Vancomycin Hypersensitivity Reactions Documented in Electronic Health Records.

Background: Vancomycin, the most common antimicrobial used in US hospitals, can cause diverse adverse reactions, including hypersensitivity reactions (HSRs). Yet, little is known about vancomycin reactions documented in electronic health records.

Objective: To describe vancomycin HSR epidemiology from electronic health record allergy data.

Safety and Outcomes of Oral Graded Challenges to Amoxicillin without Prior Skin Testing.

Background: Unconfirmed penicillin allergy poses substantial public health consequences. The most widely accepted protocol to evaluate penicillin allergy is skin testing followed by an amoxicillin challenge.

Objective: To evaluate the safety of direct oral graded challenges to amoxicillin.
