The burden of allergic diseases worldwide is such that it represents a serious public health problem that attracts considerable efforts to identify effective and safe therapies. Antihistamines are an important part of the therapeutic options for allergic diseases. Levocetirizine is the R-enantiomer of cetirizine with pharmacokinetically and pharmacodynamically favourable characteristics. It is a potent inverse agonist of H 1-receptors with anti-inflammatory/anti-allergic properties. It appears to have grater in vivo H 1-receptor occupancy comparatively with other 2 nd generation H 1-antihistamines. This may confer an advantageous efficacy and safety profile. clinical trials indicate that it is safe and effective for the treatment of allergic rhinitis, chronic urticaria and some other allergic conditions in adults and children with a minimal number of untoward reactions. It is also becoming clearer that, in addition to its being a potent antihistamine, levocetirizine has several anti-inflammatory/anti-allergic effects that are observed at clinically relevant concentrations that may enhance its therapeutic benefit.

Background. The objective was to study the taxonomic diversity of the concentration of pollen, its changes and peculiarities of the course of seasonal allergic rhinitis in Samara city. Methods. Pollen was located with gravimetric method on the glass, covered with a special mixture. Clinical and allergological examination conducted among 775 children aged from 5 to 18 years and 692 adults with symptoms of rhinitis. Results. Registered three periods of increase of concentration of pollen: spring period, summer period and summer-autumn period. The major taxa in the spring was pollen Populus - 49% and Betula - 27% during this period. In the summer period dominated pollen was Pinus - 37%, Poaceae - 28% and Betula - 22%. In summer-autumn period prevailed pollen grains Ambrosia - 63% and Artemisia - 10%, of the total number of pollen grains for this period. Clinical and allergological studies have shown that the proportion of patients with seasonal allergic rhinitis is 78% among the total number of patients with allergic rhinitis. Isolated form of seasonal allergic rhinitis was diagnosed in 22% of children and in 20% of adults. Patients of this group are allergic to pollen, weeds and compositae revealed in 68%, trees - 20%, cereals - 12% of cases. Conclusion. Qualitative and quantitative composition of aeropalynologic spectrum was established and showed the peculiarities of the course of seasonal allergic rhinitis in Samara city.

The investigation concerned the diagnostic value of following inflammation markers in patients with mild or moderate bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), chronic bronchitis and pneumonia: expired air nitric oxide (Feno) and serum levels of α 1-antitripsin and neutrophilic elastase. 93 patients were included: 6 with mild BA, 11 - with moderate BA, 17 - with mild BA and chronic bronchitis, 25 - with moderate BA and COPD, 25 - with COPD, 9 - with pneumonia. The control group consisted of 21 healthy donors. We revealed that Feno, α 1-antitripsin and neutrophilic elasthase indicate the presence of the inflammation: Feno elevation mostly related to allelrgic one, α 1-antitripsin and neutrophilic elasthase - to infection-dependent inflammation. Treatmentinduced remission of the disease leads to the decrease of α 1-antitripsin and neutrophilic elasthase, but levels are not reaching the normal values. This confirms the presence of airways inflammation during clinical remission of the disease. Elevated levels of α 1-antitripsin and neutrophilic elasthase are associated with the decreased forced expiratory volume during the first second (FEV 1 - % to the predicted values).

Allergic rhinitis (AR) in children is one of the most widespread diseases. children suffering from AR have to be under allergist and otorhinolaryngologist observation as well. there is a variety of medicine groups for AR treatment, but not all of them are preparations of choice from a position of evidential medicine. the most effective are intranasal glucocorticosteroids, especially from the last generation, having clinical efficiency and higher profile of a safety.

The prevalence of adenoid hypertrophy and allergic rhinitis data based on the study of the overall medical examination of children in 2002 and the further monitoring of children in Russia in 2005-2009 (population study) are presented. The main principles of therapy are specified. Special attention has been paid to the use of Vibrocil combination drug among children, which contains antihistamine component Dimethindene, and decongestant Phenylephrine.
