One of the key pathogenetic aspects of chronic obstructive pulmonary disease (COPD) and chronic coronary syndrome (CCS) is endothelial dysfunction. Further study on this pathological process is relevant for a better understanding of the course and increasing the treatment effectiveness of these diseases. In this context, in recent years, there has been a growing body of evidence about sirtuins which, according to the latest research results, were capable of rebalancing vasoconstrictory and vasodilatory mediators, regulating the balance in the protease-antiprotease system, protecting endothelial cells from oxidative stress and may be useful in relation to the pathogenesis of COPD and CCS.

Aim. To study changes in the levels of serum endothelial nitric oxide synthase (NOS3/eNOS) and sirtuin 1 (SIRT1) in patients with a combined course of COPD and CCS and with COPD or CCS alone.

Materials and methods. In order to study endothelial dysfunction and the role of SIRT1 in the processes of its development, we examined 60 patients with combined course of COPD and with CCS or COPD alone. The control group included 10 apparently healthy individuals. Levels of SIRT1 and NOS3/eNOS were studied by enzyme-linked immunosorbent assay, and high-sensitivity C-reactive protein (hsCRP) – by immunoturbidimetric method; clinical data and medical records were analyzed. Commonplace statistical analyses were used.

Results. The results have shown that the serum level of SIRT1 in patients with COPD and CCS was lower than that in the control group. The level of hsCRP was significantly higher in patients with the studied pathology than that in apparently healthy individuals and was the highest in patients with combined COPD and CCS. The study on serum NOS3/eNOS has showed the highest concentration in COPD patients, and it was significantly higher in all groups of patients with the studied pathology than that in healthy individuals. A direct correlation has been found between the serum level of SIRT1 and hsCRP and an inverse correlation – with the level of NOS3/eNOS.

Conclusions. Thus, the pleiotropic effects and multifaceted molecular interactions of SIRT1 are a promising direction in the search for effective new therapeutic strategies in COPD and CCS.
