Mitochondrial dysfunction in patients with respiratory diseases

Abstract

The aim of this scientific literature review was to find new solutions to urgent problems of treating respiratory diseases and reducing the associated temporary loss of ability to work and disability. The article presents the results of the analysis of 62 scientific papers published over 23 years (2001 – 2023) on mitochondrial dysfunction (MD), new methods of its diagnosis, and ways of its correction in respiratory diseases. Disorder of the energy function of mitochondria has been identified as an urgent scientific problem of respiratory medicine. It is noted that new methods of pathogenetic therapy for common and currently difficult-to-treat diseases are being developed to solve this problem. The key section of the review is devoted to the results of studies of mitochondrial dysfunction in patients with asthma, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, and pulmonary hypertension.Conclusion. The article assesses MD diagnostic methods that are potentially applicable in real clinical practice. The results of studying the electric potential of the inner mitochondrial membrane, accumulation of active forms of oxygen, production of adenosine triphosphate in blood cells, alveocytes and epithelium of the respiratory tract, as well as bronchial smooth muscle cells, endothelium and vascular smooth muscle cells in the pulmonary artery system, determination of mitochondrial DNA in biological environments are compared. Proposed methods for the correction of MD syndrome in the clinical picture of respiratory diseases are briefly covered.
