Validation of basophil CD164 upregulation for pollen allergy diagnosis.

The aim of the study was to evaluate the sensitivity and specificity of allergen-induced basophil CD164 upregulation in patients with seasonal allergic rhinitis caused by allergy to grass pollens. This study was performed in 24 patients with allergy to grass pollens, and in 25 healthy controls. The protocol for allergen-induced basophil CD164 upregulation consisted of whole blood samples processing and staining with anti-CCR3/anti-CD164 antibodies added to a buffer at the beginning of stimulation.

A new variant of the basophil activation test for allergen-induced basophil CD63 upregulation. The effect of cetirizine.

Objective: The aim of our study was to determine the diagnostic usefulness of a newly developed basophil activation test (BAT) in patients allergic to Dermatophagoides pteronyssinus and pollens. We also analyzed the influence of cetirizine on CD63 upregulation. This popular antihistamine strongly inhibits skin tests, but its impact on BAT sensitivity remains unknown and deserves at least preliminary determination.

Influence of hyperosmotic conditions on basophil CD203c upregulation in patients with food-dependent exercise-induced anaphylaxis.

Increased in vitro basophil activation in buffers of slightly elevated osmolarity in 2 cases of food-dependent exercise-induced anaphylaxis is presented. These data may suggest the importance of basophil activation degree in pathogenesis of this life threatening syndrome.

[Efficacy and safety of specific immunotherapy of upper airways allergic diseases caused by allergy to mites].

Aim Of The Study: The aim of this study was to evaluate the efficacy and safety of 3 years oral specific immunotherapy in patients with perannial allergic rhinitis and bronchial asthma caused by allergy to mites.

Material And Methods: Fifteen patients with allergic perannial rhinitis entered the study. Ten of them suffered also from bronchial asthma.

[Use of selected parameters of nasal lavage fluid in asthma severity monitoring].

Unlabelled: Allergic inflammation is a chronic disorder underlying asthma and allergic rhinitis. There is a theory "one system--one disease" connecting these two atopic diseases. Eosinophil is a major effector cell in both processes.

[Bronchial hyperreactivity to histamine and levels of serum eosinophil cationic protein in patients with non-atopic asthma].

Pathogenesis of non-atopic bronchial asthma remains still an open question. Until now there have been very few studies concerning relationship between eosinophil activation and nonspecific bronchial hyperreactivity to histamine in this form of asthma. Sixteen subjects with mild nonatopic bronchial asthma entered the study.

Membrane proteins at the interface of erythrocytes fused by treatment with polyethylene glycol.

Fusion of human red cells through the action of polyethylene glycol gives rise to pairs or higher clusters with a common membrane envelope, in which a barrier at the position of the original interface can be seen in phase contrast. At early times this septum contains lipids, as judged by labelling with a fluorescent lipophile, and transmembrane protein; this was shown by the presence of the preponderant component, band 3, detected by a fluorescent label, covalently attached before fusion at an extracellular site, or by immunofluorescence with anti-band 3 antibody. Ankyrin, which is bound to band 3, is also observed in the septum.

Comparative study between skin prick tests and TOP-CAST allergen leukocyte stimulation in diagnosis of allergic status.

A recently developed CAST-ELISA method was applied to determine allergen-induced leukocyte stimulation. This method is based on the measurement of sulfidoleukotriene secretion by peripheral blood leukocytes previously stimulated with specific allergen in the presence of interleukin 3. 24 patients allergic to different aeroallergens and some food allergens were included in this study.

CAST-ELISA test in diagnosis of mite allergy.

The recently developed CAST-ELISA method was applied to determine allergen-induced leukocyte stimulation. This method is based on the measurement of sulfidoleukotriene secretion by peripheral blood leukocytes stimulated with specific allergen in the presence of interleukin 3.23 patients allergic to Dermatophagoides pteronyssinus were included in this study.

CAST-ELISA test--a new diagnostic tool in pollen allergy.

We have applied a recently developed method called CAST-ELISA to evaluate the degree of leukocyte stimulation by specific allergen. This method is based on the measurement of sulfidoleukotriene levels in supernatants taken from previously stimulated peripheral blood leukocytes by specific allergen in the presence of interleukin 3.23 patients with pollinosis entered the study.

[Spontaneous histamine release by basophils and bronchial hyperreactivity in patients with hay fever].

Basophil spontaneous histamine release test was performed in seventeen patients suffered from seasonal allergic rhinitis before, 2 weeks after immunotherapy and during pollen season. During pollen season at the same day non-specific bronchial hyperreactivity to histamine was estimated. Values of spontaneous basophil histamine release before immunotherapy were not different from control group but significantly increased after immunotherapy and during pollen season.

Specific pollen allergen activates eosinophils of the patient with chronic allergic contact urticaria.

The aim of the study was to evaluate the activation of eosinophils in an unique case of a young man with atopy manifested as chronic pollen contact urticaria. In order to reveal the role of eosinophils in that case, the study was performed by means of monoclonal antibodies EG2 and chemiluminescence. In addition, comparative electron microscopic study of peripheral blood and skin infiltrating eosinophils were performed for which the name ultrastructural morphometric analysis of intracytoplasmic eosinophil granules has been proposed.

The behavior of T and B lymphocyte subpopulations in infectious and atopic bronchial asthma.

In 40 patients with infectious bronchial asthma and in 40 patients with atopic form of the disease, the behavior of T and B lymphocyte populations was studied by the E and EAC rosette tests. The control group consisted of 20 students unaffected by allergic diseases. A significant decrease in the percentage of E rosette forming T lymphocytes was found in the group of patients with atopic bronchial asthma, as compared with the control and infectious bronchial asthma groups (p less than 0.

T and B lymphocytes in patients with hay fever.

In 20 patients with hay fever and 19 control subjects the rosette formation test was carried out to determine T and B lymphocyte subpopulations. T and B lymphocyte subpopulations are expressed by the percentage of E, EA and EAC rosettes, respectively. Statistical analysis revealed a significant reduction in the number of E rosettes (p < 0.

Effect of histamine on the spontaneous E rosette formation after blockade of histamine H2 receptors with cimetidine.

Thirteen patients with clinical diagnosis of hay fever, were examined. T lymphocytes subpopulation was determined by the E rosette test. The present study is concerned with the effect of histamine on the ability of T lymphocytes for E rosette formation after blockade of the histamine H2 receptor with its inhibitor cimetidine.
