BACKGROUND: Dexamethasone premedication is required to prevent paclitaxel-related hypersensitivity reactions (HSRs). Oral dexamethasone (PO-D) has been considered the standard premedication regimen. However, whether intravenous dexamethasone (IV-D) is feasible for preventing paclitaxel-related HSRs is still unclear. We conducted a meta-analysis to compare these two regimens. METHODS: We performed a systematic search in the PubMed, China National Knowledge Infrastructure, and Web of Science databases for relevant articles published before June 2016...

André Pinho, Ana Marta, Inês Coutinho, Margarida Gonçalo
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...

L-asparaginase (EC 3.5.1.1), which catalyzes the deamidation of L-asparagine to L-aspartic acid and ammonia, has been widely used as a key therapeutic tool in the treatment of tumors. The current commercially available L-asparaginases, produced from bacteria, have signs of toxicity and hypersensitivity reactions during the course of tumor therapy. Therefore, searching for L-asparaginases with unique biochemical properties and fewer adverse effects was the objective of this work. In this study, cyanobacterial strain Synechococcus elongatus PCC6803 was found as a novel source of L-asparaginase...

Christine James, David I Bernstein
PURPOSE OF REVIEW: Allergen immunotherapy is the only modality that can modify the immune response upon exposure to aeroallergens and venom allergens. This review will update the allergist on recent studies evaluating safety of sublingual and subcutaneous allergen immunotherapy. RECENT FINDINGS: Multiple clinical trials and retrospective studies have been published evaluating overall safety of these therapies. The risk of systemic reactions with subcutaneous immunotherapy remains quite low, but near-fatal and fatal anaphylaxis does occur, requiring physicians to be aware of potential risks for such events...

Mycobacterium W (Mw) vaccine has been found to be effective in the treatment of leprosy and warts. Despite increasing use of Mw immunotherapy, data on its safety is limited. We report a series of eight patients who developed persisting injection site granulomatous reaction following Mw immunotherapy and were successfully treated with minocycline. Eight patients with persistent nodular swelling at the site of Mw injections were identified. Seven of them had received Mw immunotherapy for cutaneous warts and one for verrucous epidermal nevus...

Hypersensitivity reactions are commonly encountered with drugs such as beta lactams, sulphonamides, allopurinol etc., Corticosteroids are frequently employed in the treatment of drug induced allergic reactions. Therefore, it is highly unlikely that a corticosteroid itself may cause such a reaction as an adverse effect. We had encountered a rare case of hypersensitivity reaction with inhalational budesonide in an eight-year-old boy. The patient developed maculopapular rashes over the back, buttocks and legs accompanied with pruritus within four hours of administration of the first dose...

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...

There is evidence that gut commensal microbes affect the mucosal immune system via expansion of regulatory T cells (Treg) in the colon. This is mediated via short-chain fatty acids (SCFA), bacterial metabolites generated during fiber fermentation, which include butyrate, propionate and acetate. We postulated that SCFA produced by commensal skin bacteria may also activate resident skin Treg, the activity of which is diminished in certain inflammatory dermatoses. Sodium butyrate (SB) either injected s.c. or applied topically onto the ears of hapten-sensitized mice significantly reduced the contact hypersensitivity reaction...

REVIEW
Jonathan S Tam
Hypersensitivity reactions to foods can have diverse and highly variable manifestations. Cutaneous reactions, such as acute urticaria and angioedema, are among the most common manifestations of food allergy. However, cutaneous manifestations of food allergy encompass more than just IgE-mediated processes and include atopic dermatitis, contact dermatitis, and even dermatitis herpetiformis. These cutaneous manifestations provide an opportunity to better understand the diversity of adverse immunologic responses to food and the interconnected pathways that produce them...

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...

Allergic contact dermatitis is an immune-mediated antigen-specific skin reaction to an allergenic chemical that corresponds to a delayed-type hypersensitivity response (type IV reaction). Allergic contact dermatitis should be suspected when skin lesions are localized to the site of previous applications of the culprit drug. Lesions appear after re-exposure in susceptible persons, with delayed onset (more than 24 h after exposure). The gold standard for diagnosis is patch (epicutaneous) testing; identification and removal of any potential causal agents is crucial...

Allergic and hypersensitivity reactions to dental impression materials may occur throughout dental treatment, with diverse manifestations from slight redness to severe pain and a burning mouth with total stomatitis. Patients are often unaware of these allergic reactions, which makes early identification of the cause almost impossible. In addition, symptoms usually begin after 24 hours and mostly in patients with a preexisting history of allergic responses. This report describes a patient with a suspected allergic reaction to a polyether dental impression material during prosthetic rehabilitation associated with a mandibular telescopic denture...

BACKGROUND: All implant compounds undergo an electrochemical process when in contact with biological fluids, as well as mechanical corrosion due to abrasive wear, with production of metal debris that may inhibit repair processes. None of the commonly-used methods can diagnose implant allergies when used singly, therefore a panel of tests should be performed on allergic patients as pre-operative screening, or when a postoperative metal sensitisation is suspected. METHODS: We analysed patients with painful prostheses and subjects prone to allergies using the Patch Test in comparison with the Lymphocyte Transformation Test...

Drug-induced hypersensitivity reactions can significantly impact drug development and use. Studies to understand risk factors for drug-induced hypersensitivity reactions have identified genetic association with specific human leukocyte antigen (HLA) alleles. Interestingly, drug-induced hypersensitivity reactions can occur in nonhuman primates; however, association between drug-induced hypersensitivity reactions and major histocompatibility complex (MHC) alleles has not been described. In this study, tissue samples were collected from 62 cynomolgus monkeys from preclinical studies in which 9 animals had evidence of drug-induced hypersensitivity reactions...

Although formaldehyde is well known to cause type 4 hypersensitivity, immunoglobulin E (IgE)-mediated hypersensitivity to formaldehyde is rare. Here, we report a case of recurrent generalized urticaria after endodontic treatment using a para-formaldehyde (PFA)-containing root canal sealant and present a review of previous studies describing cases of immediate hypersensitivity reactions to formaldehyde. A 50-year-old man visited our allergy clinic for recurrent generalized urticaria several hours after endodontic treatment...

Fosaprepitant is a widely administered antiemetic used mainly for moderately to highly emetogenic chemotherapy. Local injection site reactions are the most common type of infusion reaction reported from fosaprepitant. At our institution, two separate patients have experienced systemic hypersensitivity reactions to their infusions of fosaprepitant. We report a review of the literature and the details of these reactions.
