Backgraund: Allergic rhinitis (AR) is a common IgE-mediated disease. Multiple mechanisms are involved in the regulation of IgE synthesis, and cytokines produced by immune cells play an important role in this process. In addition, the study of the features of immunological reactivity in seasonal AR (SAR) is of interest both getting of new data about pathogenesis of the disease and optimization of the treatment. Aims: To study the features of the cytokine status and hematological parameters in patients with SAR outside the period of exacerbation. Materials and methods: 43 adult patients with SAR (stage of remission) have been included in the study, and 47 conditionally healthy patients have formed the comparison group; perennial symptoms and/or sensitization to perennial allergens were considered as exclusion criteria. Complete blood cell count and serum IL-4, IL-5, IL-6, IL-8, IL-10, IL-18, MCP-1, total IgE, eosinophil cationic protein levels were measured. Results: The remission stage in patients with SAR is characterized by higher serum levels of total IgE and IL-8 compared with the group of healthy patients. Normal serum total IgE level in patients with SAR in remission is associated with activation of the monocyte-macrophage link (increased serum levels of MCP-1, IL-6, IL-8, absolute and relative numbers of monocytes). Increased serum total IgE level is associated with the predominant signs of the Th2-phenotype of the immune response (increased in the serum levels of IL-4, IL-5). Conclusions: Immune reactivity of patients with natural remission of SAR is characterized by Th1-phenotype features if serum level of IgE is normal and Th2-ones if IgE is increased.

Dynamics of serum proinflammatory cytokines such as interleukins (IL)-1, -2 and -6, tumor necrosis factor alpha (TNFα) was examined in patients of reproductive age suffering from acute inflammatory diseases of the pelvic organs. Our study was carried out with female patients at hospital admission prior to therapy applied with conventional methods of treatment and improved treatment by using vaginal low-frequency laser in a constant continuous magnetic field. The data obtained were compared with serum cytokine level from 20 healthy female volunteers of reproductive age consulted on better contraception methods. It was found that cytokine profile of in patients with acute inflammatory processes in pelvic organs was characterized by a high level of proinflammatory cytokines. It was shown that patients receiving conventional treatment contained decreased level of serum IL-1, IL-2, IL-6 and TNFα displaying slight dynamics, which did not reach it in control group. This may contribute to ongoing inflammatory process, despite the positive clinical dynamics. In turn, imbalance of immune responses leads to a persistently impaired fertility in women and need to perform subsequent comprehensive rehabilitation measures. Moreover, patients applied with intravaginal low-frequency laser radiation in a constant magnetic field were found to contain serum TNFα < 100 pg/ml observed in 59.7% of cases, IL-6 level was lower than 20 pg/ml (prevalent in control group) found in 54.2% of cases. Serum IL-2 level was decreased by 3.5-fold compared to baseline, whereas for IL-1β it was higher than 100 pg/ml in as few as 23.6% patients. Such temporal pattern of inflammatory markers with rapid significant decrease of serum proinflammatory cytokines in patients with preformed pathogenic factors can reduce probability of connective tissue formation and activate their own repair as well as regenerative events. The results obtained allow to wider use combined physical interventional factors for therapy of patients with acute inflammatory diseases of the pelvic organs.

BACKGROUND:Allergic diseases and gastrointestinal tract diseases can influence on the natural course of each other. AIM:To study the sensitization profile in patients with comorbidity of seasonal allergic rhinitis (SAR) and upper gastrointestinal tract inflammatory diseases (UGITID). MATERIALS AND METHODS:112 adult residents of Volgograd city suffering from SAR but without perennial symptoms and sensitization to indoor allergens have been included in the study. 31/112 patients hadH. pylori-negative and 38/112 H. pylori-positive UGITID. Control group consisted of 43/112 patients without gastrointestinal diseases. Skin prick-testing with 3 groups of pollen allergens have been carried out. RESULTS:75.9% of patients were sensitized to weed pollen; sensitization to grass pollen was in 1.53 times less, and 10.5% of patients (4/38) had positive tests with birch pollen. The sensitization to quinoa and ragweed in SAR and H. pylori-UGITID patients was comparable with control group but less common with wormwood, sumpfweed allergens. The sensitization in SAR patients andH. pylori+-UGITID was similar to the control group, but positive SPT with sunflower and corn allergens were rare then in control group. CONCLUSION:Weed pollen allergens prevail in sensitization spectrum of adult Volgograd residents with SAR. Sensitization to goose-foot and ragweed is common less in SAR patients andH. pylori-UGITID but to graminea grass and birch pollen is more often. It may be supposed that the UGITID are predisposing factors to the sensitization to cross-reacting plant food allergens. At the same time supposed immunomodulating action ofH. pylorimake the differences between AR patients withH. pylori+-UGITID orH. pylori-UGITID minor.
