allergy history. Methods: 42 patients with suspected beta-lactam hypersensitivity reactions were evaluated at a drug allergy clinic at a tertially allergy center. Skin prick tests (SPT) with major determinants (PPL), minor determinants (MDM), penicillin G, ampicillin, amoxicillin, intradermal tests (ID) and specific IgE determination were done. If all tests were negative, a drug challenge was p...

BACKGROUND Drug hypersensitivity is classically divided into IgE mediated and non-IgE mediated disease. We report a rare case of consequent IgE mediated and non-IgE mediated reactions within the beta lactam class of antibiotics. CASE SUMMARY An 84-year-old man developed toxic epidermal necrolysis (TEN) due to ceftriaxone, a third generation cephalosporin, involving 72% of the body surface are...

OBJECTIVE To study the diagnostic and treatment modalities used in drug allergy/hypersensitivity among members of the World Allergy Organization (WAO). METHODS A questionnaire comprising 39 questions was circulated electronically to member societies, associate member societies, and regional and affiliate organizations of WAO between June 29, 2009, and August 9, 2009. RESULTS Eighty-two resp...

BACKGROUND Penicillin allergy is the most commonly reported drug allergy and often presents with cutaneous symptoms. Other common diagnoses, such as chronic urticaria, may be falsely attributed to penicillin allergy. Because chronic urticaria is fairly common in the general population, evaluation of its prevalence in patients with self-reported penicillin allergy was of interest. Similarly, the...

The Food and Drug Administration (FDA) is proposing new warning labeling for all over-the-counter (OTC) drug products containing phenylpropanolamine preparations (phenylpropanolamine bitartrate, phenylpropanolamine hydrochloride, and phenylpropanolamine maleate). Phenylpropanolamine is a sympathomimetic drug that is used in OTC weight control, cough-cold, nasal decongestant, and allergy drug pr...

Drug eruptions are probably the most frequent of all manifestations of drug sensitivity. They occur in about 2% of treatment courses and are commoner in women, the elderly and in patients with the acquired immunodeficiency syndrome (AIDS), especially from sulphonamides such as in co-trimoxazole1. Drugs most often incriminated are listed in Table 1. The prevalence of a history of penicillin alle...

INTRODUCTION Recent data from literature have shown many difficulties in managing allergic diseases in primary care in most countries and a consequently clear need for standardized educational programmes. Drug allergies represent an important medical issue for general practitioners (GPs) in Romania, though no national data about incidence, severity and management exist.The aim of our study was ...
