BACKGROUND: Graded challenges are performed to exclude hypersensitivity reactions in patients with a low likelihood of drug allergy. Literature regarding optimal protocols with a defined number of steps and use of placebo is lacking. OBJECTIVE: To identify allergic drug reactions (ADRs) through a 3-step protocol composed of placebo followed by a 2-step graded drug challenge. METHODS: We performed a 5-year retrospective chart review of all patients with historical ADRs who underwent single-blind, placebo-controlled graded drug challenges between October 2010 and November 2015 at an outpatient drug allergy clinic...

Our knowledge of genetic predisposing factors of drug hypersensitivity reactions (DHRs) is still scarce. The analysis of the genetic basis of these reactions may contribute to dissect the underlying mechanisms. We will outline current knowledge of the genetic predictors of most common DHRs, including reactions to betalactam antibiotics (BLs), nonsteroidal anti-inflammatory drugs (NSAIDs) and biological agents. The predictors of DHRs to BLs are mostly linked to IgE-class switching, IgE pathway and atopy (IL4R, NOD2, LGALS3) in replicated candidate gene studies, and to antigen presentation (HLA-DRA) in the single replicated GWAS performed so far...

Adverse drug reactions (ADRs) are a relatively common cause of morbidity and mortality. Many factors can contribute to ADRs, including genetics. The degree to which genetics contributes to ADRs is not entirely clear and varies by drug, as well as the type of ADR. Pharmacogenetics and, more recently, pharmacogenomics have been applied to the field of ADRs for both predictable ADRs and hypersensitivity drug reactions. Evaluations for glucose-6-phosphate dehydrogenase and thiopurine S-methyltransferase are commonplace clinical tests to reduce hematologic problems associated with drugs, such as dapsone and azathioprine, respectively...

Hypersensitivity reactions to nonsteroidal anti-inflammatory drugs are common and five types of reactions have been defined. The prevalence of such reactions in patients with myocardial infarction is unclear, and so antiplatelet therapy in this population is a challenge. Various desensitization protocols have been developed but there are no specific guidelines for their use. The authors present the case of a patient with acute coronary syndrome and aspirin hypersensitivity referred for urgent coronary angiography...

Aspirin-exacerbated respiratory disease (AERD) is a distinct clinical condition characterized by chronic sinusitis with nasal polyps, asthma, and hypersensitivity reactions to nonsteroidal anti-inflammatory drugs (NSAIDs). Distinguishing AERD from other forms of chronic sinusitis, asthma, and NSAID reactivity has important clinical implications for management. The clinical history is helpful, but not adequate for confirming the diagnosis of AERD, in most cases. Diagnostic provocation challenge remains the only way to confirm or exclude the diagnosis of AERD...

Nonsteroidal antiinflammatory drugs (NSAIDs), including aspirin, are among the most commonly used drugs worldwide. They account for a large number of adverse drug reactions (ADRs). The prevalence of NSAID-induced reactions is increasing. Distinguishing between a predicted side effect of a drug and a potentially life-threatening hypersensitivity reaction is essential to manage the affected patient. However, most clinicians find it difficult to diagnose these types of reactions despite published classification schemes...

Suspicion for drug hypersensitivity (DH) is a common reason for children's referral to an allergy department, with β-lactam antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs) as the most frequently involved drugs. The prevalence of DH in children remains not well defined as epidemiologic studies in children are lacking, and the most of those take into account adverse drug reactions without a systematic allergy work-up to confirm or exclude hypersensitivity. The clinical history is mandatory in order to classify the reaction as being immediate or non-immediate and then to subsequently adapt the allergy work-up...

BACKGROUND: Patients with aspirin-exacerbated respiratory disease (AERD) also recently known as nonsteroidal anti-inflammatory drug (NSAID) exacerbated respiratory disease (NERD) must avoid aspirin and all other oral NSAIDs. The effect of topical NSAID (tNSAID), especially salicylates which are commonly present in topical medicated preparations, on asthma control of this phenotype is studied. METHODS: The study inclusion criteria were adults with: 1) NSAID hypersensitivity; 2) nasal polyposis/chronic rhinosinusitis; 3) not well-/poorly controlled asthma and 4) exposure to tNSAID...

INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAIDs) take first or second place as the cause of drug-induced hypersensitivity reactions. The oral provocation test (OPT) is a gold standard for the diagnosis of NSAID hypersensitivity. We investigated which analgesics patients took after a negative OPT and determined the proportion of patients that experienced a hypersensitivity reaction despite a negative OPT. METHODS: We selected 115 patients (67.8% female, age 54...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most frequent agents involved in hypersensitivity drug reactions, with NSAID-induced urticaria and/or angioedema (NIUA) being the most common entity. Mast cells are key players in NIUA and are activated by thymic stromal lymphopoietin (TSLP). This cytokine functions through recognition by its receptor, composed of IL7Rα (interleukin-7 receptor alpha) and TSLPR (TSLP receptor). These genes have been previously associated with other inflammatory diseases...

BACKGROUND: Pyrazolones are the most common causes of selective nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity. We studied a large group of patients with immediate and delayed selective responses to metamizole. METHODS: Patients with suspicion of hypersensitivity to metamizole were evaluated. We verified acetylsalicylic acid tolerance and classified patients as immediate or delayed responders if they showed symptoms less or more than 24 h after metamizole administration...

OBJECTIVES: Previously, different nonsteroidal anti-inflammatory drugs (NSAIDs) have been evaluated for their potential immunomodulatory activities. Mefenamic acid is a well-known NSAID and is used in the treatment of musculoskeletal disorders, inflammation, fever, and pain. To the best of our knowledge, promising data regarding the immunomodulatory activity of mefenamic acid is scarce. Current study investigates the immunomodulatory activity of mefenamic acid in different models of cell-mediated and humoral immunity...

Nonsteroidal anti-inf lammatory drugs (NSAIDs) are widely prescribed for the treatment of inflammatory diseases, but their use is frequently related to hypersensitivity reactions. This review outlines our current knowledge of NSAID hypersensitivity (NHS) with regard to its pathogenic, molecular, and genetic mechanisms, as well as diagnosis and treatment. The presentation of NHS varies from a local (skin and/or airways) reaction to systemic reactions, including anaphylaxis. At the molecular level, NHS reactions can be classified as cross-reactive (mediated by cyclooxygenase inhibition) or selective (specific activation of immunoglobulin E antibodies or T cells)...

Asthma and chronic rhinosinusitis are heterogeneous airway diseases of the lower and upper airways, respectively. Molecular and cellular studies indicate that these diseases can be categorized into unique endotypes, which have therapeutic implications. One such endotype is aspirin-exacerbated respiratory disease (AERD), which encompasses the triad of asthma, aspirin (or nonsteroidal anti-inflammatory drug) hypersensitivity, and nasal polyposis. AERD has unique pathophysiological features that distinguish it from aspirin-tolerant asthma and other forms of chronic rhinosinusitis...

History of drug allergy is of major concern during perioperative period. Medical records usually lack documents confirming the stated allergy. This study aimed to investigate the prevalence of self-reported drug allergies and their characteristics in adult Serbian surgical population, and to analyze their influence on drug prescription during perioperative period. The study enrolled patients scheduled for general surgery during a one-year period at a tertiary care hospital. They were questioned using a structured questionnaire about the existence of drug allergy and its nature...

Kounis syndrome is defined as an acute coronary syndrome triggered by allergic or hypersensitivity reactions resulting in mast cell and platelet activation. Numerous causes have been described, including various drugs, medical conditions, and environmental exposures. Samter's triad consists of nasal polyps, asthma, and aspirin (or nonsteroidal anti-inflammatory drug) sensitivity. We describe a case of Kounis type I in a young woman with Samter's triad who presented with cardiac arrest on 3 occasions. Ergonovine provocation testing established the diagnosis of coronary vasospasm...
