BACKGROUND: As in contact allergy, T cell-mediated hypersensitivity in non-immediate (NI) cutaneous adverse drug reactions (CADRs) to antibiotics is considered to be lifelong, but, in this setting, patch tests have rarely been repeated after long time intervals. OBJECTIVE: To evaluate the long-term reproducibility of positive patch test reactions to antibiotics in patients with NI CADRs. METHODS: Fifty-six patients with NI CADRs to antibiotics who had relevant positive reactions during patch testing were invited to repeat patch tests with a similar antibiotic series 2-15 years thereafter...

INTRODUCTION: Vernal keratoconjunctivis (VKC) is a severe form of pediatric ocular allergy, characterized by acute and chronic corneoconjunctival inflammation that may lead to visual sequelae. Although topical immunosuppressive drugs such as cyclosporine are usually effective, some severe forms may be refractory and require prolonged steroid therapy. Very few papers report the use of omalizumab in VKC in the literature. In the present study, we describe our clinical experience with omalizumab in severe VKC children...

BACKGROUND: It is considered that farm areas protect young patients from allergy and asthma due to high exposure to endotoxins. Allergen immunotherapy (AIT) is the only treatment of allergy modifying the immune response with the potential to change the natural history of allergic diseases. It seems that studies evaluating the efficacy of immunotherapy in large cohorts of allergic patients living in farm areas are needed to understand the influence of environment on immune response during AIT...

Despite using lots of progression in hypersensitivity, it is not yet a cure. Current treatment for allergy focuses on two approaches, including treats only the symptoms of allergy by utilizing drugs and the other is desensitization therapy (immunotherapy), which involves administration of specific allergens. The main obstacle to hypersensitivity permanent treatment is the IgE producing subclass of B-lymphocytes which is the source of IgE- producing in hypersensitive patients. Removal of these lymphocytes causes noticeable reduction in the levels of IgE and allergic responses significantly...

BACKGROUND: Intravenous (IV) iron preparations are widely used in the treatment of anemia in patients undergoing hemodialysis (HD). All IV iron preparations carry a risk of causing hypersensitivity reactions. However, the pathophysiological mechanism is poorly understood. We hypothesize that a relevant number of these reactions are mediated by complement activation, resulting in a pseudo-anaphylactic clinical picture known as complement activation-related pseudo allergy (CARPA). METHODS: First, the in-vitro complement-activating capacity was determined for 5 commonly used IV iron preparations using functional complement assays for the 3 pathways...

BACKGROUND: Graded challenges are performed to exclude hypersensitivity reactions in patients with a low likelihood of drug allergy. Literature regarding optimal protocols with a defined number of steps and use of placebo is lacking. OBJECTIVE: To identify allergic drug reactions (ADRs) through a 3-step protocol composed of placebo followed by a 2-step graded drug challenge. METHODS: We performed a 5-year retrospective chart review of all patients with historical ADRs who underwent single-blind, placebo-controlled graded drug challenges between October 2010 and November 2015 at an outpatient drug allergy clinic...

Drug hypersensitivity reactions may manifest with either organ-specific or systemic symptoms, but cutaneous eruptions are the most common manifestations. Different medications may cause identical skin symptoms, whereas hypersensitivity to a single drug may manifest with various patterns of symptoms depending on the pathomechanism of hypersensitivity. Drug reactions should be also taken into account in the differential diagnosis of numerous skin rashes. Analysis of morphology of drug-induced lesions, about potential immunologic or nonimmunological mechanisms, is important for the final diagnosis...

BACKGROUND: Allergic rhinitis (AR) is a common condition that can be treated with a number of different therapies. Treatments such as intranasal antihistamines (INAs) and intranasal steroids (INSs) are widely used by AR patients. For some allergy sufferers, a combination of therapies, specifically an INA and an INS, is required to address their symptoms. A new treatment, the formulation of azelastine hydrochloride and fluticasone pro-pionate used as a single spray (MP-AzeFlu), has become available for AR patients who need both types of treatment...

BACKGROUND: Longitudinal, patient-centered care represents a challenge for general practitioners (GPs), and in this context, reminder systems can offer targeted support. This study aimed to identify details of such reminders: (1) contents of care addressed, (2) their mode of display in the electronic health record (EHR), (3) their visual appearance, (4) personnel responsibilities for editing and applying reminders, and (5) use of reminders for patient recall. METHODS: This mixed-methods study comprised (1) a cross-sectional survey among 185 GP practices from a German university network, and (2) structured observations of reminder utilization in six practices based on a clinical vignette describing a multimorbid senior with 26 care needs...

BACKGROUND: Local anaesthetics (LA) are often suspected as possible causes of allergic reactions. The Danish Anaesthesia Allergy Centre (DAAC) is the national reference centre for investigation of perioperative allergic reactions. The purpose of this study was to investigate the incidence of IgE-mediated immediate type perioperative allergic reactions to LA. METHODS: In the period 2004-2013, a total of 409 patients (244 women/165 men; median age 49 years, range 1-86 years) were investigated in DAAC on suspicion of allergy associated with anaesthesia and surgery...

INTRODUCTION: H1 antihistamines are used for the treatment of nausea and vomiting during pregnancy as well as the symptomatic relief of asthma, urticaria, allergy, and the common cold. Although they are overall felt to be safe during pregnancy, recently several studies have challenged this assumption, as millions of women are exposed to them in the first trimester. METHODS: Following the guidelines of PRISMA, a systematic review was performed to retrieve all published articles involving H1-antihistamine exposure during pregnancy...

INTRODUCTION: Allergies are a problem that greatly affects the population, and hence the use of antiallergic medications is fairly widespread. However, these drugs have many adverse effects. The use of medicinal plants could be an option, but they need to be evaluated. OBJECTIVE: This study was designed to evaluate the antiallergic effect of the atomized extract of rhizome of Curcuma longa, flowers of Cordia lutea, and leaves of Annona muricata. MATERIALS AND METHODS: Twenty-four New Zealand white albino rabbits were randomized into 2 groups...

Tranexamic acid (TXA) allergy is extremely rare. An 80-year-old woman without prior exposure to TXA underwent elective knee replacement. Shortly after induction of anaesthesia and intravenous TXA, she developed hypotension, tachycardia, and facial erythema accompanied by a raised serum tryptase. Later, skin prick and intradermal testing confirmed positive responses to TXA in high dilution and with negative results to the other drugs used. While neuromuscular blocking agents, opiates, and antibiotics remain the most frequent cause of anaphylaxis during anaesthesia, allergy to TXA should always be borne in mind and requires skin testing for confirmation as there are presently no blood tests available...

Allergic diseases are driven by activation of mast cells and release of mediators in response to IgE-directed antigens. However, there are no drugs currently available that can specifically down-regulate mast cell function in vivo when chronically administered. Here, we describe an innovative approach for targeting mast cells in vitro and in vivo using antisense oligonucleotide-mediated exon skipping of the β-subunit of the high-affinity IgE receptor (FcεRIβ) to eliminate surface high-affinity IgE receptor (FcεRI) expression and function, rendering mast cells unresponsive to IgE-mediated activation...

Gastroesophageal reflux is a common phenomenon in infants, but the differentiation between gastroesophageal reflux and gastroesophageal reflux disease can be difficult. Symptoms are non-specific and there is increasing evidence that the majority of symptoms may not be acid-related. Despite this, gastric acid inhibitors such as proton pump inhibitors are widely and increasingly used, often without objective evidence or investigations to guide treatment. Several studies have shown that these medications are ineffective at treating symptoms associated with reflux in the absence of endoscopically proven oesophagitis...

Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease...

Under homeostatic conditions, as well as in various diseases, leucocyte migration is a crucial issue for the immune system that is mainly organized through the activation of bone marrow-derived cells in various tissues. Immune cell trafficking is orchestrated by a family of small proteins called chemokines. Leucocytes express cell-surface receptors that bind to chemokines and trigger transendothelial migration. Most allergic diseases, such as asthma, rhinitis, food allergies and atopic dermatitis, are generally classified by the tissue rather than the type of inflammation; making the chemokine/chemokine receptor system a key point of the immune response...
