Aim. To determine the content of heat shock proteins with molecular weight 70 kDa (HSP 70) and antibo dies to them in blood and nasal secretion in patients with allergic rhinites and infectious rhinosinusites of different etiology. Materials and methods. The paper presents the results of examination of 10 patients with allergic rhinitis and 30 patients, infected with rhinosinusites(the age range 25–35 years). The patients with infectious rhinosinusites were divided into 3 groups according to nosologic form of disease. The control group included 10 practically healthy persons in the ratio, comparable by their gender and age with sick persons. Results. The analysis showed that in the nasal secretion of all patients, HSP 70 level significantly raised compared to the control. Maximum values were registered in patients with bacterial rhinosinusitis and were higher than in patients with viral and fungous ones by 1.9 times ( p = 0.015) and 2.9 times ( p = 0.001), respectively. In blood serum, HSP 70 concentration compared with the control increased in patients with allergic rhinitis and bacterial rhinosinusitis by 103.67 % ( p = 0.015) and 32.11 % ( p = 0.049), respectively; these values in the last two groups exceeded the latter in patients with fungous RS by 2.37 times ( p = 0.01) and by 1.54 times ( p = 0.035). Conclusions. It was detected that in the group of patients with allergic rhinitis and chronic bacterial rhinosinusitis in the nasal secretion and blood serum, HSP 70 values were the highest. In the nasal secretion, HSP 70 level was higher than in blood. The amount of autoantibodies to HSP 70 in blood grew in allergic rhinitis, fungous and viral forms of rhinosinusites that reflects the immunological effect of chaperone proteins.
