BACKGROUND/AIM: The diagnosis of bronchial asthma, a chronic inflammatory disease of the respiratory tract, is made on the basis of anamnesis, pathologic auscultatory findings of the lungs, lung function disturbances, skin tests, as well as the basic indices of immunologic condition in bronchial trunk. The aim of the study was to find out correlation of objective indices of the disease and than relation with the symptoms in the patients with bronchial asthma. METHODS: The study included 60 young male non smokers with long lasting symptoms of bronchial asthma including shortness of breath, wheezing, hard breathing, nonproductive or productive cough, weakness and night hard breathing. There were no symptoms of respiratory infection over the past two months and lung radiography and spirometry were normal Based on the results of nonspecific bronchoprovocative test two groups of the patients were formed, group I (n=30) with positive histamine test (average value of the inhaled histamine concentration with FEV1 drop by 20% in regard with the initial value (PC20) = 2.99 +/- 0.51 mg/ml of histamine) and group II (n=30) with negative histamine test (PC20(a) = 14.58 +/- 6.34 mg/ml of histamine). RESULTS: The obtained spirometry results revealed a statistically significant difference in values of FEV1 between groups: I group--FEV1 3.2%; II group--EV1 = 101.8%; (p .05, Wilcoxon test), although all the FEV1 values were normal Regarding the presence of the most common symptoms there was not statistically significant difference between the groups (p>0.05, chi-square test). Pathologic auscultatory lung findings were found in 73.4% of the patients in the group I and 27.5% of the patients in the group II. There was statistically significant difference (p<0.05, chi-squared test). A positive correlation between the degree of hypersensitivity and lung physical findings was confirmed (p<0.05 Spearman's rho), but there was no correlation with FEV1 values. CONCLUSION: There is a correlation with lung pathologic physical findings, lower values of FEV1 (in a range of normal values) and the degree of nonspecific bronchial sensitivity as objective indices of activity of bronchial asthma. There is no correlation of these parameters with patient's symptoms as subjective indices of bronchial asthma.
