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.

[Ocular findings most frequently found in patients with allergic rhinoconjunctivitis].

Background: Allergic etiology is suspected whenever a patient with conjunctivitis presents the typical clinical features; however, in ophthalmic practice, confirmation of the immune disease is uncommon. Ocular involvement is common in allergic rhinitis, and the current name of this entity is allergic rhinoconjunctivitis (ARC). Conjunctivitis diagnosis in ARC is inferred by the symptoms, but the most common ocular findings in patients with a confirmed allergic disease are unknown.

[Lymphocytes B and NK in respiratory allergy].

Background: High affinity immunoglobulin E (IgE) receptors may activate the mast cell degradation; on the other hand, the ones of low affinity may activate B lymphocytes so they act as antigen-presenting cells and as producers of the same immunoglobulin. As allergic patients produce a great quantity of IgE they are prone to get an infection.

Objective: To quantify the IgE increase in 28 patients with allergic rhinitis or asthma, or both without having received a previous treatment.

[Th1 lymphocytes in patients with extrinsic asthma].

Background: Bronchial asthma is a multifactorial disease affecting the functionality of the bronchial tree and immunological changes.

Objective: To determine if lymphocytes Th-1 have a role in extrinsic asthma of Mexican patients.

Material And Methods: We included in the study 39 patients with extrinsic asthma, living in Mexico City, and 27 healthy subjects, without allergy antecedents, with nutritional and immunological characteristics similar.
