[Features of the immune status of patients with infectious-allergic bronchial asthma before the onset of an exacerbation].

A study was made of the immune status in patients with infectious-allergic bronchial asthma in the phase of clinical manifestations before the onset of exacerbation 2 mos after examination, and in patients with a favorable course of disease without exacerbations during the same period of time. The assessment of the immune status was based on a study of the balance of interrelationships in a set of immunological parameters including the chief indices of cellular and humoral immunity (T- and B-lymphocytes, phagocytosing and rosette-forming neutrophils, indices of cell activity in exercise tests, the levels of serum and secretory immunoglobulins--a total of 33 indices). Sharp changes in values and direction of interrelationships in numerous combinations of parameters, especially in those which included the content of immunoglobulins in the sputum, indices of the activity of neutrophils and exercise tests were noted in the patients with exacerbation for 2 mos after examination as compared to those who developed no exacerbations. A special table for prediction of a course of infectious-allergic bronchial asthma was based on a study of the balance of interrelationships. Data obtained from the table corresponded to considerable changes revealed in the balance of interrelationships among components of the immune system 1-2 mos before the appearance of the clinical signs of exacerbation of the disease.
