Clinical and laboratory studies the effect of chronic pneumonia on the state of the upper respiratory tract in children

Objective: to investigate the state of the upper respiratory tract (URT) in children suffering from nonspecific chronic pneumonia without clinical and medical history of the presence of associated chronic inflammatory processes on the part of the nasopharynx, and based on the results obtained, assess the nature of the effect of the chronic bronchopulmonary process on the condition URT. Material and methods. 45 children from 5 to 16 years old with chronic non-specific pneumonia were examined. We studied the endoscopic picture of the nasal cavity and bronchi, the motor activity of the ciliated epithelium of the nasal cavity, the pH of the nasal secretion, and the concentration of secretory immunoglobulins A and G class in the nasal secretion. The treatment consisted of sanitation bronchoscopy and the appointment of medications and physiotherapeutic agents in relation to the pathology of the bronchopulmonary apparatus. Results. Our studies and their interpretation showed that chronic pneumonia has an adverse effect on the state of the URT. This effect is realized through the reflex effect of the pathological process of the bronchopulmonary system on the initial section of the respiratory system. As a result of pathological reflection in the nasal cavity, paranasal sinuses, vasomotor and secretory disorders occur, which are clinically manifested in the form of edematous, stagnant phenomena, as well as increased secretion, a change in the color of the mucous membrane of the nasal cavity and a violation of a number of indicators of its functional state. Conclusion. Children with chronic nonspecific pneumonia registered at the pulmonary clinic should also be observed by URT specialists in order to timely detect the transition of the subclinical stage of the disease to the clinical and adequate treatment with the pulmonologist.
