BACKGROUND: The rate of severe cutaneous adverse drug reactions is low, and these reactions can result in death or disability. An evidence-based epidemiological study of severe cutaneous adverse drug reactions in China has not been reported. OBJECTIVE: The aim of this study was to analyze epidemiology and characteristics of severe cutaneous adverse drug reactions of Chinese inpatients during the recent 15 years with meta-analysis. METHODS: We retrospectively reviewed Chinese literature reporting severe cutaneous adverse drug reactions and collecting data from 2000 to 2015, which were in accordance with our inclusion criteria...

BACKGROUND: The drug provocation test (DPT) is considered as the gold standard to diagnose drug allergy and is particularly important in the diagnosis of nonimmediate beta-lactam (BL) allergy in children. The natural history of BL allergy remains unknown. OBJECTIVE: Our main aim was to evaluate the natural history of nonimmediate BL hypersensitivity and the long-term tolerance acquisition, and our secondary objective was to determine the negative predictive value (NPV) of the DPT following a 2-day protocol...

REVIEW
Mariana Castells
Drug allergy is a rising problem in the twenty-first century which affects all populations and races, children, and adults, and for which the recognition, diagnosis, management, and treatment is still not well standardized. Classical and new chemotherapy drugs, monoclonal antibodies (MoAbs), and small molecules to treat cancer and chronic inflammatory diseases are aimed at improving quality of life and life expectancy of patients, but an increasing number of reactions including anaphylaxis precludes their use in targeted populations...

We evaluated the prevalence of and risk factors for hypersensitivity reactions related to carboplatin, which is commonly used to treat gynecological malignancies. All women with pathologically documented ovarian, fallopian tube, or primary peritoneal cancer treated with carboplatin alone or a carboplatin-based combination chemotherapy regimen at a single hospital between January 2006 and December 2013 were retrospectively recruited. We analyzed the incidence, characteristics, risk factors, management, and outcomes of carboplatin-related hypersensitivity reactions among these patients...

BACKGROUND: Rituximab (Rituxan) hypersensitivity (RITS) can be severe and limits the ability to further administer the treatment. Understanding its pattern and desensitization may permit administration in difficult cases. OBJECTIVE: Analyze RITS patient characteristics, hypersensitivity pattern, and desensitization outcomes to optimize management. METHODS: Twenty-five patients with RITS were referred to the Allergy/Immunology Unit at Massachusetts General Hospital over 5 1/2 years...

Drug hypersensitivity reactions (DHRs) represent growing health problem worldwide, affecting more than 7% of the general population and represent an important public health problem. However, knowledge in DHRs morbidity and mortality epidemiological data is still not optimal and international comparable standards remain poorly accessed. Institutional databases worldwide increasingly use the WHO International Classification of Diseases (ICD) system to classify diagnoses, health services utilization and death data...

G Lezmi, F Alrowaishdi, A Bados-Albiero, P Scheinmann, J de Blic, C Ponvert
BACKGROUND: A minority of children reporting non-immediate reactions to beta-lactams (BLs) are allergic. Allergy workup usually includes late-reading (48-72h) skin tests (ST) and short (1-3 days) drug provocation tests (DPT), regardless of the chronology of the index reaction. The sensitivity of hyper-late-reading (≥ 6-7 days) ST and of prolonged DPT for the diagnosis of non-immediate hypersensitiviy to BLs are yet to be determined. OBJECTIVES: To establish the diagnostic values of late- and hyper-late-reading ST and of prolonged DPT in children reporting non-immediate reactions to BLs...

Vocal cord dysfunction, also known as paradoxical vocal fold motion (PVFM), is a disorder characterized by abnormal vocal cord adduction during inspiration. PVFM is commonly misdiagnosed as asthma because of the similarity of symptoms: cough, wheezing, chest pain, and dyspnea. We present the clinical vignette of a 36-year-old woman with juvenile rheumatoid arthritis and multiple adverse drug reactions who presented with recurrent episodes of unrecognized PVFM during skin testing for drug allergy, omalizumab treatment, and tocilizumab desensitization...

β-Lactam drugs (penicillins, amoxicillin, and cephalosporins) account for 42.6% of all severe drug-induced anaphylaxis. In this review, we focus on clinically significant immunologic cross-reactivity in patients with confirmed penicillin allergy to cephalosporins, and the structural involvement of the R1 and R2 chemical side chains of the cephalosporins causing IgE-mediated cross-reactivity with penicillin and other cephalosporins. Skin tests predict IgE-mediated reactions and showed cross-reactivity between penicillins and early generation cephalosporins that shared side chains, but confirmatory challenge data are lacking...

BACKGROUND: Hypersensitivity reactions to nonsteroidal anti-inflammatory drugs (NSAIDs) in children are becoming a great concern. Most studies have focused on adults, with noted discrepancies observed in the classification of hypersensitivity reactions to NSAIDs in children when compared with adults. OBJECTIVE: To phenotype a group of children with hypersensitivity reactions to NSAIDs, including paracetamol, and analyze the degree of agreement with the entities reported in adults and how they fit the proposed classifications...

REVIEW
Allison Eaddy Norton, Ana Dioun Broyles
Proper management of drug allergy in children is based on a thorough history, in vitro testing (if available), in vivo testing, and drug challenge. This approach has been well developed with beta-lactam drugs but not with non-beta-lactam drugs and monoclonal antibodies. Children commonly develop rashes during an antibiotic course, which can lead to misdiagnosis of drug allergy. Clinical reactions to monoclonal antibodies vary and are managed depending on the type. A better knowledge of drug reactions that can occur in antibiotic allergy and monoclonal allergy can aid a provider in better management of their drug-allergic pediatric patients...

BACKGROUND: Reports of selective reactions to clavulanic acid (CLV) have increased in recent decades because of its increased prescription in combination with amoxicillin (AX) as AX-CLV. Basophil activation test (BAT) is used for diagnosing beta-lactam immediate hypersensitivity and is the only available in vitro assay for diagnosing patients with immediate hypersensitivity to CLV. However, few studies, and with limited numbers of patients have been published. OBJECTIVE: The aim of this study was to establish the sensitivity, specificity, and negativization rates of BAT to AX and CLV...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequently involved in drug hypersensitivity reactions (DHR). NSAIDs are prescribed for different processes and some NSAIDs can be obtained over the counter. Areas covered: We analyse the practical approaches for managing and treating NSAID-DHR considering the five major groups of entities recognised, divided into two categories: those responding to strong COX-1 inhibitors and possibly weak COX-1 or selective COX-2 inhibitors named cross-intolerant (CI), and those induced by a single drug or drug group with good tolerance to strong COX-1 inhibitors, known as allergic reactions (SR)...

Incidence of allergic disorders in children has increased significantly over time due to environmental and life-style changes. These include allergic rhinitis, atopic dermatitis, allergic conjunctivitis, food allergies, bronchial asthma, drug allergies, insect bites and anaphylaxis; most being IgE-mediated type 1 hypersensitivity reactions to common environmental and food antigens. Although most of them are self-limiting, they may adversely affect the quality of life and sometimes become life-threatening as well...

Contrast-enhanced radiological examinations are important diagnostic tools in modern medicine. Currently, all approved and available iodinated and gadolinium-based contrast agents are safe and well-tolerated by most patients. However, approximately 2% of patients receiving iodinated contrast media exhibit hypersensitivity reactions. Patients with a history of such a reaction are at increased risk upon reexposure. Therefore, they are subjected to a prophylaxis such as injection of antiallergy drugs or general anaesthesia...

BACKGROUND: Identifying the cause of periprocedural hypersensitivity reactions (HSRs) remains challenging because of the multitude of medications involved. Antibiotics are the most common cause in the United States, whereas neuromuscular blocking agents are most common in Europe. OBJECTIVE: To identify causative agents for periprocedural HSRs. METHODS: This study was a 7-year retrospective medical record review of patients evaluated between December 2009 and January 2017 at a drug allergy center in Bronx, New York for periprocedural HSRs, defined as occurring soon before, during, or soon after a medical procedure or operation with or without general anesthesia...

BACKGROUND: Adverse reactions to local anesthetics (LAs), especially esters, are not uncommon, but true allergy is rarely diagnosed. To our knowledge, currently there is no reliable method of determining IgE-mediated hypersensitivity to LAs and cocaine. OBJECTIVE: To assess the clinical value of allergy tests (prick, IgE, challenges, and arrays) in people suffering hypersensitivity reactions (asthma and anaphylaxis) during local anesthesia with cocaine derivatives and drug abusers with allergic symptoms after cocaine inhalation...

BACKGROUND: Beta-lactam antibiotics (BLA) are the most commonly prescribed antibiotics and are responsible for the majority of immediate hypersensitivity reactions to drugs in children. Cross-reactivity is important in hypersensitivity to BLAs because these drugs all share a common beta-lactam structure and some share similar side chains. OBJECTIVE: The aim of this study was to evaluate the clinical characteristics of patients who are diagnosed with immediate-type BLA hypersensitivity and frequency of patients with side chain hypersensitivity, "selective responders...
