Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE) is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI) tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions...

We describe a case of a woman who developed three separate episodes of urticaria and ana-phylaxis during exercise after consuming an apple, with immunological evidence that nonspecific lipid transfer proteins (LTP) may have been responsible for these reactions. LTP sensitivity can cause life-threatening allergies and anaphylaxis. Although LTP sensitization is common in Mediterranean countries, the frequency of knowledge and diagnoses is increasing in Europe. Despite the geographic differences, LTP allergy should be kept on sight when facing severe anaphylaxis after consuming LTP-included food...

Background. Follow-up data about the onset of novel food allergies in patients allergic to lipid transfer protein (LTP) are missing. We investigated the occurrence of novel allergies over time in LTP hypersensitive patients. Methods. Sixty-seven LTP-allergic patients recommended to avoid foods responsible for systemic reactions and encouraged to eat other sensitizing foods avoiding the association with known co-factors, were re-evaluated after ≥ 1 year to assess the occurrence of allergy to novel foods. IgE to rPru p 3, rBet v 1, and r Phl p 12 were measured...

In the past decade, new diabetes technologies, including continuous glucose monitoring (CGM) systems, support patients with diabetes in their daily struggle with achieving a good glucose control. However, shortly after the first CGM systems appeared on the market, also the first concerns about adverse skin reactions were raised. Most patients claimed to suffer from (sometimes severe) skin irritation, or even allergy, which they related to the (acrylate-based) adhesive part of the device. For a long time the actual substance that caused these skin reactions with, for example, the Flash Glucose Monitoring system (iscCGM; Freestyle® Libre) could not be identified; however, recently Belgian and Swedish dermatologists reported that the majority of their patients that have developed a contact-allergic while using iscCGM react sensitively to a specific acrylate, that is, isobornyl acrylate (IBOA)...

Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 32-year-old woman with triamcinolone-induced immediate hypersensitivity reaction, in which the patient had a positive prick test result with triamcinolone...

Wogonoside, the main effective constituent of traditional Chinese medicine Scutellaria , belongs to the glucuronide family, with various functions, including detoxification, anti-inflammation and nourishing gallbladder, lowering blood pressure, diuresis and anti-allergic reactions. However, the effects of wogonoside on human colon cancer cells remain unclear. The present study aimed to investigate the anticancer effect of wogonoside on human colon cancer cells in vitro and its anticancer mechanisms. The results demonstrated that wogonoside significantly inhibited cell growth, induced apoptosis and mitochondrial-mediated autophagy of colon cancer cells...

The prevalence of food allergy has risen dramatically in the last two decades. Primary care providers encounter food-allergic children on a daily basis. Although the standard of care has traditionally been strict avoidance of the allergen and advisement to carry an epinephrine autoinjector in case of an accidental exposure resulting in a severe reaction, food allergy research has progressed in the past decade concerning various immunotherapies that may provide an alternate treatment strategy. Oral immunotherapy (OIT), performed under the supervision of an allergist, is the most widely studied of these therapies...

Biosimilar insulins have expanded treatment options for diabetes. We compared clinical efficacy and safety between biosimilar and originator insulins by meta-analysis. Random effects meta-analysis was performed on randomized controlled trials comparing biosimilar and originator insulins in adults with diabetes from electronic databases up to December 2017. Ten trials (4,935 patients) were assessed (2 each for LY2963016, MK-1293, Mylan's insulin glargine, and SAR342434, and 1 each for FFP-112 and Basalog). Meta-analysis revealed no differences between long-acting biosimilar and originator insulins for reduction of hemoglobin A1c at 24 weeks (0...

BACKGROUND: Therapeutic plasma exchange (TPE) is an extracorporeal procedure which consists of removing the patient's plasma and replacing it with an appropriate replacement fluid. Plasma and blood cells are separated by a centrifugation process. Our department has used TPE for several years, and in 2013 we introduced an institutional apheresis protocol. The main objective of this report is to describe the TPE procedures performed between 2013 and 2016 in the Peruvian population. METHODS: We analyzed the technical and clinical aspects of 864 centrifugal TPE procedures as well as the associated complications...

Atopic dermatitis (AD) is a common, highly pruritic, chronic inflammatory skin disease. Dysfunction of the epidermal barrier is witnessed by an increased transepidermal water loss in lesional and non-lesional AD skin. The inflammation in lesional AD skin is well characterized. Non-lesional skin of AD patients shows histological signs of a subclinical inflammation and a pro-inflammatory cytokine milieu. This microinflammation is present even in seemingly healed skin and must be taken into account regarding treatment of AD...

Rhododendron album Blume (RA) has traditionally been used as an herbal medicine and is considered to have anti‑inflammatory properties. It is a well‑known medicine for treatment of allergic or atopic diseases. In the present study, the biological effects of an RA methanol extract (RAME) on inflammation were investigated in tumor necrosis factor‑α (TNF‑α)/interferon‑γ (IFN‑γ)‑stimulated human keratinocytes. The present study aimed to investigate the potential mechanisms by which RAME inhibited TNF‑α/IFN‑γ‑induced expression of chemokines [thymus‑ and activation-regulated chemokine (TARC) and macrophage‑derived chemokine (MDC)] and cytokines [interleukin (IL)‑6 and IL‑8] through the nuclear factor‑κB (NF‑κB) pathway in human keratinocytes...

OBJECTIVES: Doripenem is a broad-spectrum parenteral carbapenem with enhanced activity against Pseudomonas aeruginosa and Enterobacteriaceae. Current dosing regimens recommend the administration of 0.25-0.5 g once daily in patients undergoing intermittent renal replacement therapy. As patients are usually dialyzed thrice weekly, we aimed to investigate a 1-g post-hemodialysis regimen, thus reducing treatment costs and enhancing patient compliance. A second objective of this trial was to describe the pharmacokinetics of intradialytic doripenem...

Allergic rhinitis (AR) is mediated by many proinflammatory and anti-inflammatory cytokines as interleuhin-17 (IL-17) and interleukin-35 (IL-35) respectively. We assessed the effect of allergen specific immunotherapy (IT) on the serum levels of IL-17 and IL-35 in patients with AR sensitive to house dust mites (HDMs). Twenty patients with AR sensitive to HDMs and ten healthy control subjects were included in the study. Sensitivity to HDMs was diagnosed by positive skin prick test. Patients were treated by cluster IT...

Precautionary allergen labeling (PAL) also known as "may contain" labeling has been applied to many packaged food products around the world. PAL is a voluntary form of labeling whose original intent was to help ensure that packaged foods were as safe as possible for allergic consumers by alerting them to the possible presence of allergen residues resulting from the use of shared processing equipment, shared processing facilities, or other industry practices. However, the proliferation of PAL and the myriad of various phrasing used as PAL statements are confusing to consumers and serve to diminish their quality of life...

Biodegradable polymer nanoparticles are an important class of materials used in several applications for their unique characteristics. In particular, the ones stabilized by zwitterionic materials are gaining increased interest in medicine as alternative to the more common ones based on poly(ethylene glycol) thanks to their superior stability and ability to avoid both the accelerated blood clearance and allergic reactions. In this work, a novel class of zwitterionic based NPs has been produced, and a method to independently control the nanoparticle size, degradation time, and polymer molecular weight has been developed and demonstrated...

The application of biologics such as monoclonal antibodies for targeted therapy may lead to immediate adverse drug reactions with different pathophysiological mechanisms. Some of them are due to the immunogenicity of these drugs and are truly allergic, some of them are non-allergic, some are on-target, and some are off-target. The main example of non-allergic reactions are infusion reactions, mainly induced by cytokine release. They generally occur already at the first application and symptoms may decrease in subsequent applications...

BACKGROUND: Food allergy is an increasing public health issue and the commonest cause of life-threatening anaphylactic reactions. Conventional allergy tests assess for the presence of allergen-specific IgE, significantly overestimating the rate of true clinical allergy resulting in over-diagnosis and adverse impact on health-related quality of life. OBJECTIVE: To undertake initial validation and assessment of a novel diagnostic tool, the mast cell activation test (MAT)...
