简要总结

The composition of the intestinal microbiota, the level of lipopolysaccharides, TMAO in the blood, and other parameters of patients with COPD (n=50), asthma (n=50) and the control (n=40) will be assessed as factors associated with exacerbations and respiratory symptoms in the prospective study (12 months).

详细描述

The patients from "Biobank of blood and feces for the development of a clinical and biological platform as a basis for an innovative approach to the prevention of chronic non-infectious diseases based on the composition of the intestinal microbiota" study will be included (cross-sectional study). The protocol of the above study included the assessment of socio-demographic, anthropometric data, clinical blood pressure (BP), ECG, blood tests, fecal microbiota studies, spirometry data, diet questionnaire. ABPM, HBP, other questionnaires (mMRC, CAT, ACQ-5, GMBQ) will be added to initial data (=visit 1). Than the four visits (2-5th visits) in 3 each months will be performed to assess respiratory symptoms, exacerbations of COPD/asthma, respiratory infections, therapy, BP, and other parameters. The standard statistical methods will be used.
