AimTo evaluate the efficacy of mechanical bacterial lysate on the prevention of infectious exacerbations of chronic obstructive pulmonary disease in patients with frequent exacerbations.Materials And MethodsThe study included patients (n=60) with frequent exacerbations of COPD (groups C and D according to the GOLD classification). All COPD patients were divided into two groups by blind method. The first group (n=30) received conventional therapy for COPD plus MBL (the course included 3 cycles of 10 days therapy with 20-day intervals between them). The second group of patients (control, n=30) received conventional therapy for COPD without MBL.We evaluated the severity of symptoms, frequency of recurrence of COPD exacerbations, readmissions, need for emergency care and changes in basic therapy of COPD. Evaluations were done on 10 days, 1, 3 and 6 months from the start of the study.ResultsAdding of MBL to the therapy list of COPD resulted in a significant decrease of biomarkers of systemic inflammation and sputum purulence during compared to the control group. After 6 months of observation MBL group demonstrated statistically significant improvement of respiratory function, decrease in frequency of COPD exacerbations, needs for emergency medical service, reduced changes in basic therapy and hospitalization for exacerbation of COPD. Therapy with MBL showed a high degree of safety and low incidence of adverse events.ConclusionThe results of the study indicate that MBL may be used for the prevention of severe infectious exacerbations of COPD.
