Clinical and Immunological Efficiency of Bacterial Vaccines at Adult Patients With Bronchopulmonary Pathology

Pathogenetic Justification and Clinical and Immunological Efficiency of Application Bacterial Vaccines at Adult Patients With Bronchopulmonary Pathology

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.

Methods: Immunoglobulin G (IgG)-antibodies against Streptococcus pneumoniae (S. pneumoniae) - solid-phase enzyme-linked immunoelectrodiffusion essay (ELISA). General levels of Immunoglobulin A (IgA), Immunoglobulin M (IgM), IgG, Immunoglobulin E (IgE) in sera - radial immunodiffusion.

Microbiological examination of sputum. Determining the clinical effectiveness of vaccination. the number of exacerbations of chronic bronchopulmonary pathology for the year prior to vaccination and during the first and fourth years after vaccination; the number of courses of antibiotic therapy a year prior to vaccination and during the first and fourth years after immunization; the number of hospitalizations for acute exacerbations of chronic bronchopulmonary disease during the year prior to vaccination and during the first and fourth years after immunization. Method of estimating quality of life associated with health in patients with chronic bronchopulmonary pathology (asthma control questionnaire (ACQ-5), COPD assessment test (CAT)). Characteristics of variables (arms 1-8). The age of patients (years): mean (standard deviation) [min; median; max] for normally distributed variables; median [Q25; Q75] - for variables with distribution different from normal.

Evaluation of early post-vaccination period The General condition (satisfactory/unsatisfactory) Local reactions: pain (n/%), redness (n/%, cm), consolidation (n/%, cm) General reactions: Temperature 37,0-37,5 (n/%) Temperature of 37.6-38,5 (n/%) A temperature of 38.6 and > (n/%) Headache (n/%) Malaise, fatigue (n/%) Joint pain (n/%) Muscle pain (n/%) Health related quality of life (HRQoL): CAT-test (for Chronic obstructive pulmonary disease (COPD) patients), ACQ-5 (for asthma patients).

32 patients with COPD. Standard therapy, vaccinated with pneumococcal polysaccharide vaccine/pneumococcal conjugate vaccine (PPV23/PCV13).

Number of Patients Without Exacerbations of the Underlying Disease, Antibiotic Use and Hospitalisation.

Number of patients without exacerbations of the underlying disease, antibiotic use and hospitalisation.

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.

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.

Phagocytic Activity in Patients With COPD at Baseline, 1, 2, and 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.

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)).

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.
