The study of the combined course of chronic pancreatitis and diabetes mellitus present a particular interest. The purpose of the study was to determine the effectiveness of correction of exocrine pancreatic insufficiency of the pancreas in patients with chronic pancreatitis and diabetes mellitus types 1 and 2 with using of different forms and doses of polyenzyme drugs. Material and methods. 126 patients with diabetes mellitus and chronic pancreatitis were examined. The patients were divided into 2 groups: 1 group included 62 patients with type 1 diabetes mellitus, and 2 group comprised 64 patients with type 2 diabetes. All surveyed patients underwent general clinical, anthropometric, instrumental and laboratory methods of investigation. Patients of both groups were divided into subgroups depending on the method of correction of exocrine pancreatic insufficiency, namely 1.1 and 2.1 subgroups received tableted polyenzyme preparation with minimal lipase activity of 10000 IU as enzyme therapy, and 1.2 and 2.2 subgroups received mini-tableted polyenzyme preparation with minimal lipase activity of 25000 IU. Results and discussion. The use of mini-tableted polyenzyme preparation with minimal lipase activity of 25000 IU according to the results of C13-mixed triglyceride and C13-amylase breath tests was an effective method for the correction of exocrine insufficiency of the pancreas in patients with chronic pancreatitis and diabetes mellitus types 1 and 2. We detected a statistically significant increase of the maximally concentration of 13CO2 between 150 and 210 minutes of the study (up to 9.2±0.4% 1.2 subgroup and up to 9.7±0.5% in patients 2.2 subgroup), as well as the total concentration of 13CO2 in at the end of 360 minutes of the study (up to 19.7±0.6% and up to 27.3±1.1%) according to the results of C13-mixed triglyceride breath tests, p<0,05. Conclusion. The use of a mini-tableted polyenzyme preparation with a minimum lipase activity of 25000 IU was a more effective method for correction of exocrine pancreatic insufficiency in patients with chronic pancreatitis and type 1 and 2 diabetes mellitus, than using a tableted polyenzyme preparation in a dose of 20000 IU per main meal. The study results showed that using C13-mixed triglyceride and C13-amylase breath test were highly informative methods for evaluating the effectiveness of enzyme replacement therapy in exocrine pancreatic insufficiency in patients with chronic pancreatitis and type 1 and 2 diabetes. The use of a mini-tablet polyenzyme drug in patients with chronic pancreatitis and type 1 and 2 diabetes mellitus is an effective means to normalize the manifestations of malabsorption in terms of α1-antitrypsin clearance
