The choice of drugs used to treat patients with chronic obstructive pulmonary disease (COPD) (inhaled β-agonists, M-anticholinergic drugs, inhaled corticosteroids (ICS)) in view of their interchangeability is reviewed in this article. This aspect is especially important for clinicians when choosing an effective and safe treatment for COPD and for increasing patient adherence to treatment.The aim of this study was to assess the ratio of the number of reference (original), interchangeable, and generic drugs used in COPD.Methods. In accordance with the Russian clinical guidelines 2018 and GOLD 2019, modern drugs for the treatment of COPD with bronchodilator and anti-inflammatory activity were selected. All trade names of the corresponding drugs for each international non-proprietary name (INN) In the State Register of Medicines website were considered. The information on the availability of reference (original) drugs and the corresponding interchangeable products, as well as their presence in the List of vital and essential drugs was analyzed.Results. A large number of generic prodcuts are registered in the State Register of Medicines, and only a few of them are interchangeable with the corresponding reference (original) drug.Conclusion. The analysis will help widen the doctors’ choice of interchangeable drugs in treatment of COPD with an equivalent effect and safety of reference drugs, as well as to increase the patients’ adherence to treatment.

Airway inflammation is a central feature of many airway diseases such as asthma, chronic bronchitis, bronchiectasis and chronic cough; therefore, it is only logical that it is measured to optimize its treatment. However, most treatment recommendations, including the use of anti-inflammatory therapies such as corticosteroids, are based on assessments of only airflow and symptoms. Over the past 10 years, methods have been developed to assess airway inflammation relatively noninvasively. Quantitative cell counts in sputum and the fraction of exhaled nitric oxide are the most validated tests. Judicious use of currently available drugs, such as corticosteroids, bronchodilators and antibiotics, and other anti-inflammatory therapies guided by sputum eosinophil and neutrophil counts, have been demonstrated to decrease exacerbations of asthma and chronic obstructive pulmonary disease, ameliorate cough, improve quality of life in patients with these diseases and is cost effective compared with treatment strategies based on guidelines that do not incorporate these measurements. Thus, it is unfortunate that this is not used more widely in the management of airway diseases, particularly in patients with severe asthma and chronic obstructive pulmonary disease who experience frequent exacerbations.

Abstract Background: Chronic obstructive pulmonary disease (COPD) is an incurable and debilitating chronic disease characterized by progressive airflow limitation associated with abnormal levels of tissue inflammation. Therefore, stem cell-based approaches to tackle the condition are currently a focus of regenerative therapies for COPD. Extracellular vesicles (EVs) released by all cell types are crucially involved in paracrine, extracellular communication. Recent advances in the field suggest that stem cell-derived EVs possess a therapeutic potential which is comparable to the cells of their origin.Methods: In this study, we assessed the potential anti-inflammatory effects of human umbilical cord mesenchymal stem cell (hUC-MSCs) derived EVs in a rat model of COPD. EVs were isolated from hUC-MSCs and characterized by the transmission electron microscope, western blotting, and nanoparticle tracking analysis. As a model of COPD, male Sprague Dawley rats were exposed to cigarette smoke for up to 12 weeks, followed by transplantation of hUC-MSCs or application of hUC-MSCs-derived EVs. Lung tissue was subjected to histological analysis using hematoxylin and eosin staining, alcian blue-periodic acid Schiff (AB-PAS) staining, and immunofluorescence staining. Gene expression in the lung tissue was assessed using microarray analysis. Statistical analyses were performed using GraphPad Prism 7 version 7.0 (GraphPad Software, USA). Student’s t-test was used to compare between 2 groups. Comparison among more than 2 groups was done using one-way analysis of variance (ANOVA). Data presented as median±standard deviation (SD).Results: Both, transplantation of hUC-MSCs and application of EVs resulted in a reduction of peribronchial and perivascular inflammation, alveolar septal thickening associated with mononuclear inflammation, as well as a decreased number of goblet cells. Moreover, hUC-MSCs and EVs ameliorated the loss of alveolar septa in the emphysematous lung of COPD rats and reduced the levels of NF-κB subunit p65 in the tissue. Subsequent microarray analysis revealed that both hUC-MSCs and EVs significantly regulate multiple pathways known to be associated with COPD. Conclusions: In conclusion, we show that hUC-MSCs-derived EVs effectively ameliorate by COPD-induced inflammation. Thus, EVs could serve as a new cell-free based therapy for the treatment of COPD.
