Drug Hypersensitivity Reactions

The current development of the pharmaceutical industry in the synthesis of new chemical compounds, standardized treatment protocols, and disease prevention can lead to a progressive increase in drug hypersensitivity reactions, which often have serious consequences for human health. Increasing evidence of involvement of infections, including Herpesviridae viruses, in the development of drug hypersensitivity reactions is known.The method of flow cytometry can be used, in particular, the basophil activation test to diagnose drug hypersensitivity reactions. The anamnestic, clinical, andlaboratory data of 368 people were analyzed for the selection of patients at risk of drug hypersensitivity for the basophil degranulation test execution. It was found that among patients hypersensitivity reactions were most often detected to antibiotics (50.0%), radiopaque substances (27.7%), perioperative drugs, local anesthetics - 13.6% each. Clinical manifestations of these reactions were urticaria with angioneurotic edema (40.6%), urticaria (28.1%), anaphylaxis (21.9%), obstructive bronchitis chenges (9.37%). According to anamnestic and clinical-laboratory data, patients with a high risk of drug hypersensitivity reactions revealed frequent manifestations of herpesvirus infection HSV1 (34.4%), active chronic persistence of EBV (59.4%), accompanied by manifestations of EBV-associated secondary immune disorders and prevalence of chronic EBV infection in all patients.

Delayed Reactions

Drug hypersensitivity reactions (DHRs) are typically classified into immediate and delayed reactions based on the time interval between drug exposure and onset of symptoms. Clinical manifestations range from mild to severe and life-threatening reactions. The most severe clinical entities are anaphylaxis and anaphylactic shock for immediate reactions, and severe cutaneous adverse reactions such as Steven Johnson Syndrome and Toxic Epidermal Necrolysis for delayed reactions. The diagnosis is complex and challenging, as drug provocation tests and even skin tests can be very risky procedures, which makes them not recommended. Therefore, it is necessary to search for useful early biomarkers to manage the diagnosis of these reactions. These biomarkers could be useful to determine the clinical entity, but not to identify the culprit drug. Some of the currently available biomarkers are few genetic associations of drug allergy with polymorphisms of human leukocyte antigen (HLA), the detection of inflammatory and lipid mediators in serum, or the detection of cytokines, chemokines, and cytotoxic markers in skin biopsies. In this literature review, it has been summarize the immunological mechanisms involved in severe reactions, both immediate and delayed, and different early biomarkers: those currently used for the diagnosis of these reactions as well as possible early biomarkers that could be useful with further studies to standardize their clinical use.

Drug hypersensitivity reactions are among the most important problems that arise when using drugs. The occurrence of such reactions in the population is at least 7% and tends to a constant increase. The most frequent manifestations of drug hypersensitivity reactions are medically induced skin lesions.The aimof this research was to study and analyze the cases of development of skin drug reactions on the basis of the reports on the adverse reactions (ADRs) of the drugs, registered in the Republic of Crimea in the period from 2009 to 2016.Materials and methods.The objects of the research were report cards about the adverse reactions, registered in the regional base (registry) of spontaneous messages called ARCADe (Adverse Reactions in Crimea, Autonomic Database) for the period from 2009 to 2016. During the analysis of the report cards, 2,698 cases of the development of skin drug reactions arising in response to the use of drugs in patients were selected. The study of the frequency of occurrence of skin drug reactions in the application of various groups of drugs was carried out taking into account the codes of the Anatomical Therapeutic Chemical (ATC) Сlassification System of drugs of the World Health Organization (WHO).Results.Of the study showed that the development of skin drug reactions was most often associated with the use of antimicrobial agents for internal use, nonsteroidal anti-inflammatory drugs (NSAIDs), drugs for the treatment of diseases of the gastrointestinal tract and agents that affect the nervous system. Among the clinical manifestations of skin drug reactions, generalized and localized rashes prevailed, and itching and hyperemia of the skin were much less common in patients. The analysis of age categories showed that the most frequently medically induced reactions occurred in children from birth to 3 years, as well as in the age group of patients from 46 to 60 years. The risk factors identified in the course of the analysis, were female gender, early childhood and old age, as well as the presence of aggravated drug allergy history.Conclusion.Drug hypersensitivity reactions create certain difficulties in clinical practice related to the diagnosis, treatment and prophylaxis, and may also cause danger to health or life of patients. In this connection, the study of such adverse reactions is the most important task of practical health care and requires direct participation of doctors of all specialties.

Abstract Purpose To describe a series of non-immediate drug hypersensitivity reactions after intravitreal anti-vascular endothelial growth factors (anti-VEGFs). Patients and methods Retrospective report of 6 patients with cutaneous non-immediate drug hypersensitivity reactions following intravitreal anti-VEGF injections, 4 after ranibizumab, 1 after bevacizumab and 1 after aflibercept. Results Clinical manifestations ranged from mild maculopapular rash, purpura to severe generalized erythroderma, with or without systemic involvement such as microscopic hematuria and proteinuria or fever. In two out of the six patients, reintroduction of either the same or an alternative anti-VEGF drug did induce a recurrence of the drug hypersensitivity reaction, while 4 patients showed no recurrence. Conclusion Cutaneous non-immediate drug hypersensitivity reactions secondary to intravitreal anti-VEGF may occur. Continuation of the same drug or switch to another anti-VEGF may either induce recurrence or be well supported by the patient. The decision of drug discontinuation should be guided by the severity of the disease.

Non-steroidal anti-inflammatory drugs (NSAIDs) are the main triggers of drug hypersensitivity reactions in children. According to the EAACI latest classification NSAIDs hypersensitivity reactions are differentiated into cross-reactive reactions, with non-immunological mechanisms (based on COX-1 inhibition), and selective reactions, with immunological mechanisms. Paediatric clinical manifestations of NSAID hypersensitivity are typically cutaneous, but sometimes, similarly to anaphylaxis, can involve other systems, especially the respiratory one. Differentiating between NSAID intolerance and NSAID allergy through drug provocation tests is crucial for the patient because the two clinical entities require different management.

The disease caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ie, coronavirus disease 2019 (COVID-19), has become a global pandemic since it was first reported in Wuhan, China in December 2019. Its severe clinical manifestations, which often necessitate admission to intensive care units, and high mortality rate represent a therapeutic challenge for the medical community. To date, no drugs have been approved for its treatment, and various therapeutic options are being assayed to address the pathophysiological processes underlying the clinical manifestations experienced by patients. New and old drugs administered as monotherapy or in combination to immunologically compromised patients may favor the development of adverse drug reactions, including drug hypersensitivity reactions, which must be identified and managed accordingly. Given the lack of herd immunity and the high rate of viral contagion, new cases are expected to emerge in the coming months. Thus, the probability of more adverse reactions or even new clinical manifestations may increase in parallel. Allergists must receive updated information on these treatments, as well as on the management of possible drug hypersensitivity reactions.

Immediate hypersensitivity to drugs is characterized by symptoms such as hives, swelling, and wheezing. To prevent a negative impact on care, assessment by an allergist is important. Evaluation requires a clear clinical history, but it is often lacking or vague, which makes a diagnosis difficult. Allergists instead can use skin testing and drug challenge to evaluate drug hypersensitivity reactions, which help the patient and provider understand the causative drug(s) and, more importantly, enables the use of the exonerated drug(s). Although penicillin skin testing is standardized, well described, and widely used, skin testing for most other drugs requires the use of a nonirritating skin testing concentration that can have a low negative predictive value. Drug challenges are the criterion standard for confirming tolerance. The allergist must obtain an in-depth clinical history and then follow with skin testing and/or drug challenges when indicated to determine which drugs can be de-labelled and which should be avoided. In this review, we focused on the evaluation of drug hypersensitivity reactions to antibiotics, perioperative agents, biologics, and chemotherapeutics.

Drug Hypersensitivity Reactions

Drug hypersensitivity reactions are clinically heterogenous ranging from mild to severe. Most drug hypersensitivity reactions are accompanied by cutaneous manifestations. Fever, mucous membrane involvement, large blisters, facial oedema, pustulosis and visceral involvement are clinical features that lead to suspicion of severe adverse drug reactions. Severe cutaneous adverse drug reactions (SCARs) include Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash eosinophilia and systemic symptoms, acute generalized exanthematous pustulosis. Serum sickness like reactions, drug induced vasculitis and generalized bullous fixed drug eruptions are less severe clinical entities. SCARs are uncommon but associated with significant morbidity and mortality. Physician should be aware of specific red flags and danger signs to immediately identify these reactions. Immediate drug withdrawal is mandatory. Early diagnosis and appropriate treatment significantly affect the prognosis of the disease. The purpose of our review is to discuss clinical phenotypes of severe cutaneous drug hypersensitivity reactions.
