The purpose of the study is to analyze the state of proteolytic and fibrinolytic activities of blood plasma in patients with chronic pancreatitis combined with hypothyroidism. Materials and methods. 105 people participated in our study, of which group 1 consisted of patients with chronic pancreatitis (n = 27), group 2 – patients with hypothyroidism (n = 30), group 3 – patients with chronic pancreatitis combined with hypothyroidism (n = 28), group 4 – almost healthy individuals (n = 20). The state of fibrinolytic activity of blood plasma was studied by lysis of azofibrin, followed by determination of total fibrinolytic activity, non-enzymatic fibrinolytic activity and enzymatic fibrinolytic activity. Assessment of the state of the proteolysis system was studied by lysis of azoalbumin (breakdown of low molecular weight proteins), azocasein (breakdown of high molecular weight proteins) and azocol (breakdown of collagen). Results. When analyzing the results of the study, we observe a probable increase in lysis of azoalbumin by 1.89, 1.96 and 2.16 times (p <0.05) in groups 1, 2, 3 compared with the group of almost healthy individuals. In patients with chronic pancreatitis and hypothyroidism, the most pronounced degradation of low molecular weight proteins was observed, which was 13.86% and 9.75% (p <0.05) higher than in the first and second groups. Indicators of azocasein lysis by 52.48%, 56.35% and 95.03% (p <0.05) were found in groups 1, 2, 3 compared with almost healthy individuals. Azocasein lysis was higher by 27.89% and 24.73% (p <0.05) in patients with chronic pancreatitis combined with hypothyroidism than in patients in groups 1 and 2. Azocol lysis was significantly higher by 10.85%, 12.05%, 16.87% (p <0.05) in groups 1, 2, 3 compared with almost healthy individuals. In addition, in patients with comorbid pathology there was an increase in lysis of azocol by 5.3% and 4.3% (p <0.05) compared with the first and second groups. The total fibrinolytic activity of blood plasma was 8.3%, 6.7%, 16.26% (p <0.05) lower in patients of groups 1, 2, 3 compared with almost healthy individuals. Non-enzymatic fibrinolytic activity of blood plasma was 44.89%, 49.64%, 66.27% higher in groups 1, 2 and 3 than in almost healthy individuals. Enzymatic fibrinolytic activity of blood plasma was 44.28%, 42.25%, 90.57% (p <0.05) lower in group 1, 2, 3 compared with the group of almost healthy individuals (p <0,05). There was a decrease in the level of enzymatic fibrinolytic activity of blood plasma by 32.07% and 33.96% (p <0.05) in patients with chronic pancreatitis associated with hypothyroidism compared with participants in groups 1 and 2 without comorbid pathology. Conclusion. The most pronounced changes in proteolytic (increased lysis of azoalbumin, azocasein, azocol) and fibrinolytic (decrease in total, non-enzymatic and enzymatic) activities of blood plasma in patients with chronic pancreatitis associated with hypothyroidism were determined
