Abstract:
Previous studies explored multifactorial interactions and sirtuin expression in the aortic cells of laboratory rodents and humans. Human studies were limited due to the availability of biological material exclusively in the advanced stage of the disease. The role of sirtuins in aortic pathology has not been explained extensively therefore the aim of the study was to assess the plasma concentrations of human sirtuin 1 (SIRT1) and human sirtuin 2 (SIRT2) in patients with ascending aortic dissection and ascending aortic aneurysm. Material and methods The study group included 43 adults (34 males and 9 females) aged 44–92 years with ascending aortic dissection ( n = 10) or with ascending aortic aneurysm ( n = 33). The SIRT1 and SIRT2 plasma concentrations in patients’ blood samples were determined, and the differences between groups were observed ( p = 0.02 for SIRT1, p = 0.04 for SIRT2). Results Levels of both SIRT1 and SIRT2 were lower in patients with ascending aortic dissection (SIRT1: median = 6.5 ng/mL; SIRT2: median = 5.7 ng/mL) than in patients with ascending aortic aneurysm (SIRT1: median = 9.2 ng/mL; SIRT2: median = 7.8 ng/mL). The SIRT1 and SIRT2 cut-off levels differentiating both groups of patients were 6.7 ng/mL and 3.2 ng/mL, respectively. Conclusions The patients with ascending aortic dissection had lower plasma concentrations of SIRT1 and SIRT2 than the patients with ascending aortic aneurysm. Calculated cut-off values for both enzymes may be helpful in laboratory differentiation of ascending aortic dissection from ascending aortic aneurysm.
