Identification of an allergenic calmodulin from Amaranthus palmeri pollen.

Introduction: Pollens are an important source of allergens that trigger rhinitis or asthma. The allergenic extracts of pollens used to diagnose and treat allergies contain different allergenic antigens. Isolated allergenic proteins are employed in in vitro assays, skin tests and allergenic-specific immunotherapy.

[Modified tests basophil degranulation and leukocyte migration inhibition factor in drug allergy. Study 2009-2014].

Background: Adverse reactions to drugs are increasing and there are few studies for the diagnosis.

Objective: To determine the utility of modified basophil degranulation (MBD) test and modified leukocyte migration inhibition factor (MLMIF) test to prove drug hypersensitivity.

Methods: 177 patients of both sexes were studied with the diagnosis of drug hypersensitivity, determining MBD, MLMIF, or both, between 2009 and 2014.

[Usefulness of studies looking for autoimmunity in patients with spontaneous chronic urticaria].

Background: Chronic spontaneous urticaria (CSU) is a common condition in adults, especially among women; this entity is frequently associated with autoimmune diseases. Our goal is to assess through laboratory studies whether patients with autoimmune CSU presented data.

Material And Method: A cross-sectional study of 35 patients was done in the area of Allergy and Immunology at Hospital Juarez de Mexico diagnosed with CSU.
