Allergic sensitization pattern of patients in Brazil

J. pediatr. (Rio J.); 97 (4), 2021
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 ...

Identification of a thaumatin-like protein as a new allergen in persimmon (Diospyros kaki) with cross-reactivity with banana (Musa acuminata)

Allergy to persimmon (Diospyros kaki ) has been only rarely reported. The antigenic composition of the fruit is not entirely known. Thaumatin-like proteins (TLPs) have been described as allergens in pollens and various fruits, such as kiwi and banana, but not in persimmon. We report the case of a 22-year...

Molecular diagnosis and immunotherapy selection in a Portuguese population sensitized to grass and olive pollens

Introduction: Phleum pratense (Phl p) and Olea europaea (Ole e) are common allergenic pollen. Objectives: To describe the sensitization patterns to Phl p and Ole e allergens in a subset of allergic rhinitis patients with positive skin prick tests (SPTs) to these pollens and compare the allergen immunothe...

Molecular sensitization profile of patients with lipid transfer protein syndrome and associated clinical characteristics

Introduction: Lipid transfer proteins (LTPs) can cause a diversity of food allergy phenotypes, broadly defined as LTP syndrome. Objective: The aims of this study were to characterize the molecular profile of patients with this syndrome and to evaluate any possible association with clinical phenotypes. Me...

Posicionamento da Associação Brasileira de Alergia e Imunologia sobre o manejo da imunoterapia específica com alérgenos (ITA) em pacientes vacinados contra COVID‑19

A pandemia de COVID-19 representa um grande desafio para todas as especialidades médicas. A imunoterapia com alérgenos (ITA) é considerada o único procedimento terapêutico capaz de modificar a história natural das doenças alérgicas, e caracteriza o estado da arte na área de Alergia e Imunologia....

Aerobiología de polen del olivo en las ciudades de Tacna y Arica y su relación con las enfermedades alérgicas respiratorias

Medir la concentración del polen en la atmósfera se ha convertido en objeto de interés a nivel mundial debido al aumento de las enfermedades alérgicas, ya que en muchas personas es causa de polinosis. Objetivos: se centró en la elaboración de un calendario de polen del olivo, basado en medir su con...

Allergens of the urushiol family promote mitochondrial dysfunction by inhibiting the electron transport at the level of cytochromes b and chemically modify cytochrome c1

Biol. Res; 54 (), 2021
BACKGROUND: Urushiols are pro-electrophilic haptens that cause severe contact dermatitis mediated by CD8+ effector T-cells and downregulated by CD4+ T-cells. However, the molecular mechanism by which urushiols stimulate innate immunity in the initial stages of this allergic reaction is poorly understood....

“Experimentando” a alergia à marijuana (Cannabis sativa), e os porquês de ficarmos “ligados”

O primeiro relato de reação alérgica à Cannabis sativa foi publicado em 1971, com a descrição de uma mulher de 29 anos que após fumar maconha pela primeira vez apresentou sintomas compatíveis com uma reação anafilática. A alergia à maconha pode manifestar-se por sintomas diversos, inclusive g...

Characterization of the sensitization profile of bee venom allergic patients – Association with the severity of reaction?

Introduction: Bee venom (BV) allergy, a common cause of anaphylaxis in adults, is often associated with severe reactions. The use of component-resolved diagnostics (CRD) increases diagnostic accuracy. Objectives: To characterize the sensitization profile of BV allergic patients and a possible correlation...
