Background: Asthma is an inflammatory chronic illness, in which mastocyt cells, basophils, T lymphocytes, eosinophils and cytokines play a role. Its association with the production of TH2 cytokines is not well known, but it is considered an aberrant immune response, yielding the activation and recruitment of a number of effector cells (mastocyts/eosinophils) and the appearance of clinical symptoms.
Objective: To determine the serum values of the interleukins 2, 4, 5, 6 and 12 and gamma interferon in relation to the severity degree of asthma and the time of immunotherapy in patients with stable chronic allergic bronchial asthma.
Background: Chronic urticaria is characterized by erythematous wheals during more than 6 weeks. In 47% of the patients it is associated to Helicobacter pylori infection; in 50%, to antibodies (Abs) against the high affinity receptor of the IgE, and in 12 to 20% to antithyroid's antibodies (antithyroglobuline, mychrosomals) and, from these, 25% have alterations of the thyroid function.
Objective: To determine the presence of the anti-Helicobacter pylori and anttihyroids antibodies and the high affinity anti-receptor of the IgE in healthy subjects and patients with chronic urticaria.
Background: The introduction of the evaluation tools, such as the quality of life-questionnaires, allows to assess how functional alterations due to an illness affect the patient's life.
Objective: To know the emotional, social and occupational state of allergic rhinitis patients.
Material And Methods: Quality of life questionnaires were applied once to a group of 50 patients with allergic rhinitis diagnosis from the clinic immunology and allergy service, from May to August 2002.
Background: The allergic asthma is the reversible chronic inflammatory process at the airways, secondary to exaggerate reply to the allergens exposition, its treatment includes: avoiding the exposure to allergens, pharmacology therapy and the specific immunotherapy with allergens (ITA), which is based on the growing dosages of the extract allergenic; the objectives are to modify the immune response and to improve the allergic disease. The ITA can fail due to causes attributable to the patient, vaccine-inherent causes and/or factors related to the allergic disease.
Objective: To determine the main causes of specific immunotherapy with allergens' failure in our hospital.
Background: To know the alterations in the microcirculation of the placenta, umbilical cord, as well as the immune and hemorrheologic disorders in preeclampsia-eclampsia.
Material And Methods: Two groups were conformed, 30 patients each, all of them with pregnancy of more than 24-week gestation. Group A included patients with preeclampsia-eclampsia and group B (control group) included women with normal pregnancy.
