Omeprazole is a proton pump inhibition and ranitidine is an H2 histamine receptor antagonist widely used in the treatment of gastroesophageal reflex disease, peptic ulcer disease, Zollinger-Ellison syndrome and as a protector of the gastric mucosae. We report a case of occupational contact allergy to omeprazole and ranitidine. A 48-year-old man, with no pre-existing history of atopy or lifestyle factors. He neither had any medical history of consumption of drugs such as ranitidine and omeprazole. He worked for 19 months in the pharmaceutical company that manufactured ranitidine base...

Risk factors for intraoperative immediate-type hypersensitivity reactions may require allergological evaluation. We report the case of a hairdresser with a positive history of penicillin hypersensitivity and anaphylactic shock during previous general anesthesia, whose in vivo and in vitro allergy tests were positive for neuromuscular blocking agents, opioids, and midazolam. Immediate-type hypersensitivity reactions to antibiotics and professional exposure to hairdressing products might induce simultaneous cross-sensitization to multiple drugs that are commonly used during general anesthesia...

PURPOSE: Recently, generic drugs of paclitaxel have been commonly used mainly by economic reasons; however, predictive factors for toxicities are not fully determined. Hypersensitivity reaction (HSR) is one of the most important adverse events in the paclitaxel-based therapy, and sometimes leads to lethal condition. The aim of the study was to identify predictors for HSR in patients treated with paclitaxel-based regimens. METHODS: All the patients treated with chemotherapy including paclitaxel at our hospital between 1998 and 2013 were retrospectively evaluated...

BACKGROUND: Penicillins are the drug family most commonly associated with hypersensitivity reactions. Current guidelines recommend negative skin tests (ST) before re-administering penicillins to patients with previous nonimmediate reactions (NIR). OBJECTIVE: The objective of this study was to examine whether ST are necessary before re-administering penicillin to patients with NIR. METHODS: Patients with NIR to penicillins starting longer than 1 hour after last dose administration or starting any time after the first treatment day or patients with vague recollection of their reaction underwent penicillin ST...

Perioperative anaphylaxis is an iatrogenic clinical condition, most often after anesthetic induction. Several mechanisms are implicated, including IgE- and non-IgE-mediated mechanisms. Perioperative anaphylaxis tends to be severe and has a higher mortality rate than anaphylaxis in other settings. This is partly due to factors that impair early recognition of anaphylaxis. Neuromuscular blocking agents, latex containing products, and antibiotics are the most common etiology. Chlorhexidine and dyes are increasingly culprits...

Hypersensitivity reaction or allergy, initially perceived as a secondary disorder, is now believed to be a major public health. For instance, contact dermatitis is a type IV delayed-type hypersensitivity reaction to skin allergens. An estimated 15-20% of the general population has acquired contact allergy. To maintain immune tolerance our immune system need to differentiate between harmful non-self and innocuous non-self. Living organisms have developed during their evolution a set of biological mechanisms to protect them from the "outside": physical barrier, inflammation, cell-based mechanisms, metabolism and elimination and biochemical pathways such as glutathione...

Purpose: Carboplatin-based regimens have proven efficacy in children with cancer. However, the development of hypersensitivity reactions (HSRs) may have a negative impact on treatment intensity and patients' outcome. The aim of this review is to summarize the incidence and the clinical features of HSRs occurring in children with cancer treated with carboplatin and their impact on treatment efficacy. Methods: Data were collected by searching for relevant studies on the incidence, clinical features and management of possible side effects about the use of carboplatin in children, published from March 1987 to October 2016 in the PubMed database...

INTRODUCTION: Antiepileptic drugs are widely used and are associated with numerous side effects including skin eruptions. Epicutaneous tests have been used with variable success in skin drug reactions. The purpose of this study was to evaluate the profitability of epicutaneous tests in delayed hypersensitivity reactions induced by antiepileptic drugs. METHODS: We analyzed all cases of allergic skin reactions to antiepileptic drugs notified in regional pharmacovigilance center of Sfax (Tunisia) between June 1, 2014 and April 30, 2016...

Non-immediate cutaneous reactions (i.e., occurring at least 1 h after the initial drug administration), particularly maculopapular exanthemas and urticarial eruptions, are common during beta-lactam treatments. A T cell-mediated pathogenic mechanism has been demonstrated in some cutaneous reactions, such as maculopapular exanthema, fixed drug eruption, acute generalized exanthematous pustulosis, and drug-induced hypersensitivity syndrome. In the diagnostic work-up, patch testing is useful, together with delayed-reading intradermal testing...

OBJECTIVE: Self-reported penicillin allergy is common among patients attending the ED, but is a poor predictor of true immunoglobulin E-mediated hypersensitivity to penicillin. We hypothesise that with a combination of skin testing and drug provocation testing, selected patients can be safely de-labelled of their allergy. METHODS: This prospective study enrolled a sample of patients presenting to an urban academic ED between 2011 and 2016 with a self-reported allergy to penicillin...

Insulin allergy has been uncommon since the introduction of human recombinant insulin preparations; the prevalence is 2.4%. Insulin injection could elicit immediate reactions, which are usually induced by an IgE-mediated mechanism, within the first hour after drug administration. In the present study, we describe the case of a child who experienced immediate urticaria after long-acting insulin injection. A 9-year-old girl affected by type I diabetes mellitus referred a history of three episodes of urticaria 30 min after insulin subcutaneous injection...

Allergic contact dermatitis (ACD) is a delayed-type hypersensitivity (DTH) reaction induced by repeated contact with sensitizers. The ability of a chemical to act as a sensitizer has most frequently been tested in animals. As the use of animals for these purposes is gradually and globally being phased out, there is a need for reliable in vitro surrogate assays. Currently proposed in vitro assays are designed to test four key events of the adverse outcome pathway (AOP) involving covalent modification of self-proteins by sensitizers (haptenation) and presentation of new antigens (hapten/carrier complexes) to the immune system...

PURPOSE: To describe the patient's allergic response to anti-vascular endothelial growth factor drugs after receiving intravitreal bevacizumab for choroidal neovascularization. METHODS: Clinical case report. RESULTS: Formal allergy evaluation revealed hypersensitivity to bevacizumab and ranibizumab, but not to pegaptanib or aflibercept. CONCLUSION: Bevacizumab and ranibizumab are derivatives of murine monoclonal antibodies, whereas pegaptanib is an aptamer and aflibercept is a fusion protein of human origin...

BACKGROUND: For most physicians, quantification of drug-specific immunoglobulin E (drug-sIgE) antibodies constitutes the primary in vitro measure to document immediate drug hypersensitivity reactions (IDHR). Unfortunately, this is often insufficient to correctly identify patients with IgE-mediated IDHR and impossible for non-IgE-mediated IDHR that result from alternative routes of basophil and mast cell activation. In these difficult cases, diagnosis might benefit from cellular tests such as basophil activation tests (BAT)...

BACKGROUND: Chemotherapy induced nausea and vomiting (CINV) is a side effect, and has negative effect on quality of life and continuation of chemotherapy. Despite new regimen and drugs, the problems still remain and standard guidelines, effective treatment and supportive care for refractory CINV are still not yet established. Persian medicine, the old Iranian medical school, offer Persumac (prepared from Rhus Coriaria and Bunium Persicum Boiss). OBJECTIVE: The specific objectives were to assess the effect of Persumac on the number and severity of nausea and vomiting in refractory CINV in acute and delayed phase...

BACKGROUND AND OBJECTIVES: Individuals who develop drug hypersensitivity reactions (DHRs) to chemically unrelated nonsteroidal anti-inflammatory drugs (NSAIDs) are considered cross-hypersensitive. The hallmark for this classification is that the patient presents a reaction after intake of or challenge with acetylsalicylic acid (ASA). Whether patients react to 2 or more NSAIDs while tolerating ASA remains to be studied (selective reactions, SRs). Objective: To identify patients with SRs to 2 or more NSAIDs including strong COX-1 inhibitors...

We describe an observational survey of diagnostic pathways in 104 patients attending four specialist allergy clinics in the United Kingdom following perioperative hypersensitivity reactions to chlorhexidine reactions. The majority were life-threatening. Men undergoing urological or cardiothoracic surgery predominated. Skin prick testing and specific immunoglobulin (sIg)E testing were the most common tests used for diagnosis. Fifty-three per cent of diagnoses were made on the basis of a single positive test...

PURPOSE: An initiative to determine the effects of penicillin skin testing (PST) from an antimicrobial stewardship perspective is described. SUMMARY: Penicillin allergy is one of the most frequently reported allergies; however, only about 10% of self-reports of penicillin allergy are accurate. Incorrect penicillin allergies are therefore a significant barrier to antimicrobial stewardship, with important clinical and economic implications, including increased antimicrobial resistance, an increased overall cost of care, increased length of stay, and, ultimately, increased mortality...
