1. Allergic sensitization pattern of patients in Brazil
Abstract Objective Allergic sensitization is one of the key components for the development of allergies. Polysensitization seems to be related to the persistence and severity of allergic diseases. Furthermore, allergic sensitization has a predictive role in the development of allergies. The aim of this study was to characterize the pattern of sensitization

2. What can we learn from measuring IgE to allergens and allergen components in tropical and subtropical settings in Brazil?
Abstract Objective This narrative, non-systematic review provides an update on the genetic aspects of the SARS-CoV-2 virus and its interactions with the human genome within the context of COVID-19. Although the main focus is on the etiology of this new disease, the genetics of SARS-CoV-2 impacts prevention, diagnosis, prognosis, and the development of thera

3. Food allergen labeling: compliance with the mandatory legislation in Brazil
Abstract Food allergies are reproducible adverse reactions mediated by specific immunological mechanisms that occur in sensitive individuals after consumption of a certain food. It is recommended that the allergic person excludes from the diet the food that triggers the allergic reactions. In Brazil, the Collegiate Board Resolution nº 26 of July 2, 2015, es

4. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

5. Evaluation of the presence of allergens in children's products available for sale in a big city
Abstract: Children's products are considered safe by the general population and doctors. Labels with terms such as "hypoallergenic" or "dermatologically recommended and tested" denote trust and credibility with the idea that they can be used by any individual. Patients with allergic contact dermatitis may be sensitive to allergens present in any product, inc

6. Homology modeling and epitope prediction of Der f 33
Dermatophagoides farinae (Der f), one of the main species of house dust mites, produces more than 30 allergens. A recently identified allergen belonging to the alpha-tubulin protein family, Der f 33, has not been characterized in detail. In this study, we used bioinformatics tools to construct the secondary and tertiary structures and predict the B and T cel

7. Impact of Bacille Calmette-Guérin revaccination on serum IgE levels in a randomized controlled trial
Abstract INTRODUCTION: Bacille Calmette-Guérin (BCG) downmodulates allergen-specific IgE levels and prevents other atopic responses in experimental models but fails to protect against respiratory allergies. Human responsiveness to BCG is variable and may interfere with protection. METHODS: Multivariate models were evaluated to test the possible effect o

8. Sensitization to cat allergen and its association with respiratory allergies: cross-sectional study
ABSTRACT Cats are a significant source of allergens that contribute towards worsening of allergic diseases. The aim of this study was to investigate the association between sensitization to cat allergens and allergic respiratory diseases.This was an observational retrospective study based on the skin pricktests results of patients at a tertiary-level hospita

9. Allergy to hypoallergenic nail polish: does this exist?
Abstract The main allergen responsible for contact dermatitis to nail polish is tosylamide-formaldehyde resin. The so-called hypoallergenic nail polishes are suposedly free of agents that commonly trigger reactions. The commercially available products and their compositions were studied. It was observed that most brands present at least one component capable

10. Highlights in the knowledge of brown spider toxins
Abstract Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function. The signs and symptoms observed following a brown spider bite are called loxoscelism. Brown spi

11. Cloning, structural modelling and characterization of VesT2s, a wasp venom hyaluronidase (HAase) from Vespa tropica
Abstract Background: Wasp venom is a complex mixture containing proteins, enzymes and small molecules, including some of the most dangerous allergens. The greater banded wasp (Vespa tropica) is well-known for its lethal venom, whose one of the major components is a hyaluronidase (HAase). It is believed that the high protein proportion and activity of this e

12. Program for Contact Allergen Research (PPAC) - a new tool for dermatologists
Abstract: In Brazil there is no classification of dermatological products by the presence of vehicles with sensitizing potential. The objective of this study is to create a database to classify such products based on the absence of the selected allergens, aiming at making it available for medical consultation. We conducted an observational study, from the co
