Prevenar-13
BiologicalConjugate 13 serotype pneumococcal vaccine
Other names: PCV13
NCT Number: NCT02787863
Goal: to to examine the formation of postvaccination immunity and evaluate the therapeutic effect of bacterial vaccines in patients with inflammation diseases of bronchopulmonary system. Objectives of the study: assessment of microbiocenosis mucous membranes of the upper respiratory tract in patients with bronchopulmonary pathology before and after use of bacterial vaccines. Identification of mayor lymphocytes subpopulations in patients in the dynamics of the vaccination process. Study the profile of humoral immune response in patients under different schemes of vaccination. Assessment of the clinic and functional status bronchopulmonary system in the immunized patients.

Conjugate 13 serotype pneumococcal vaccine
Other names: PCV13
Polysaccharide 23-valent pneumococcal vaccine.
Other names: PPV23
Time frame: Baseline (1 year prior to vaccination), 1 year after vaccination, 4 years after vaccination
Number of patients without exacerbations of the underlying disease, antibiotic use and hospitalisation.
Time frame: Baseline (1 year prior to vaccination), 1 year after vaccination, 4 years after vaccination
The number of exacerbations of the underlying disease, antibiotic use and hospitalisation. The average number of exacerbations per 1 patient = total exacerbations in the group / number of patients in the group. This is not a mean value.
Time frame: Baseline, after 1 and 4 years after vaccination
Seeding frequency S. pneumoniae from sputum in patients with COPD
Time frame: Baseline, after 1 and 4 years after vaccination
CAT - COPD Assessment Test, min. = 0, max. = 40, higher scores mean a worse outcome.
ACQ-5 - Asthma control questionnaire, min. = 0, max. = 6, higher scores mean a worse outcome.
Time frame: Baseline, 1, 2, 6 weeks after PCV13 and PPV13 vaccination
Phagocytic index (granulocytes), phagocytic index (monocytes), activity of a spontaneous HCT test (neutrophils), activity of an induced HCT test (neutrophils), percentage of HCT-positive white blood cells in a spontaneous test. The phagocytic index was calculated according to the following formula: phagocytic index = (total number of engulfed cells/total number of counted macrophages) × (number of macrophages containing engulfed cells/total number of counted macrophages) × 100 (phagocytic index)
The phagocytic index was calculated by counting at least 100 bacteria phagocytized by certain number of phagocytic cells/macrophages and expressed following formula (Mamnur Rashid 1997):
Phagocytic index = Total no. of phagocytized bacteria /No of phagocytic cells phagocytizing bacteria.
Activation index = % formazan positive cells (FPC) in NBT stimulated / % formazan positive cells (FPC) in NBT Spontaneous.
Time frame: Baseline, 1, 2, 6 weeks after PCV13 and PPV13 vaccination
Immunophenotype of blood lymphocytes in patients with COPD at baseline, 1, 2 and 6 weeks after PCV13 and PPV23 vaccination. It was pre-specified to report data from only the "COPD - Prevenar-13" and the "COPD - Pneumo-23" Arms/Groups for this Outcome Measure". This is due to the fact that we tried to study the effect of PCV13 and PPV23 on immunity values. The study of the immunological effects of vaccination in the early post-vaccination period was carried out in 2 groups of patients: 20 patients with COPD vaccinated with PCV13; 20 patients with COPD vaccinated with PPV23. These patients were selected from patients of the main groups (COPD - Prevenar-13 (1), COPD - Pneumo-23 (3)).
Time frame: Baseline, 1, 2, 6 weeks after PCV13 and PPV13 vaccination in COPD
IgA, IgM, IgG, IgE, circulating immune complexes (CIC) in serum at baseline, 1, 2 and 6 weeks after vaccination. It was pre-specified to report data from only the "COPD - Prevenar-13" and the "COPD - Pneumo-23" Arms/Groups for this Outcome Measure". This is due to the fact that we tried to study the effect of PCV13 and PPV23 on immunity values. The study of the immunological effects of vaccination in the early post-vaccination period was carried out in 2 groups of patients: 20 patients with COPD vaccinated with PCV13; 20 patients with COPD vaccinated with PPV23. These patients were selected from patients of the main groups (COPD - Prevenar-13 (1), COPD - Pneumo-23 (3)).
Time frame: Baseline, 1 and 4 years after vaccination
CD45RO expression on lymphocytes in serum at baseline, 1 and 4 years after vaccination. These patients were selected from patients of the main groups.
Time frame: Baseline, 1 and 12 months after vaccination
Mean specific IgG levels in vaccinated patients with COPD to S. pneumoniae serotypes at baseline, 6 and 12 months after vaccination
