Drug Challenges

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.

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.

Abstract Introduction As new coronavirus has spread globally, economic instability in healthcare systems has been significant. This reality is especially accentuated in Ecuador where, the shortage of healthcare workers combined with cultural and macroeconomic factors have led it to face the most aggressive outbreak in Latin America. In this context, the participation of medical students on the front line is indispensable. Appropriate training on COVID-19 is an urgent need that universities and health systems must guarantee. We aimed to describe the knowledge, attitudes and practices in Ecuadorian final year medical students in order to identify the knowledge gaps, perceptions and behavior patterns which could guide the desig3n of better medical education curricula regarding COVID-19. Methods This descriptive 33-item online survey conducted between April 6 to April 20 sent by email and by Facebook and WhatsApp. Results 309 students responded to the survey. 88% scored high (≥ 70% correct) for knowledge of the disease. The majority of students were pessimistic about possible government actions, which is reflected in the negative attitude towards the control of COVID19 in Ecuador and volunteering during the outbreak (77%, and 58% of the students, respectively). Moreover, 91% of students said they did not have adequate protective equipment or training in their health facilities. Conclusions Ecuador has a capable upcoming workforce that could benefit from an opportunity to strengthen, improve and advance their training in preparation for COVID-19. Creating a national curriculum may be one of the most effective ways for all students to be trained, while simultaneously focusing on the students’ most pressing concerns.
