• BACKGROUND: «The vicious circle» of associations of diabetes mellitus (DM) with pancreatic pathology, when pancreatic diseases can initiate DM, and type 2 DM — cause functional and organic pancreatic pathology, determines the search for possible associations. Some studies have established a relationship between TNF or TP53 polymorphisms with DM or with pancreatic diseases. AIMS: to determine and compare fasting plasma glucose and the frequency of hyperglycemia in patients with acute pancreatitis (APp), chronic pancreatitis (CPp), pancreatic cancer (PCp) depending on gender, etiology or stage of the disease, polymorphism -308G/A TNF gene in all patients, and polymorphism 72Arg/Pro gene TP53 in PCp.. MATERIALS AND METHODS: At the observational multicenter clinical cross-sectional uncontrolled case-study 44 APp, 97 CPp and 45 PCp were examined; the groups were comparable by sex/age. Informed consent form for participate in the study was obtained from all patients. The main outcome of the study: frequency of hyperglycemia in APp, CPp, PCp, considering the polymorphism TNF and TP53 genes.  RESULTS: The lowest age-standardized fasting plasma glucose (FPG) was found in CPp (6,2±0,2 mmol/l) than in APp (6,7±0,2 mmol/l, p=0,041). In PCp (6,6±0,2 mmol/l), the average levels of FPG did not differ substantially when compared with APp (p=0,749) or CPp (p=0,092). In APp, the norm of GP was detected less frequently (31,8%) than in CPp (54,6%, χ2 =6,3, p=0,012), and the frequency of the norm of GP in PCp (48,9%) did not differ with that in APp or CPp. The frequency of FPG≥6,1<7,0 mmol/l did not differ in APp (20,5%), CPp (9,3%) or PCp (17,8%). The frequency of FGP≥7.0 mmol/l did not differ in APp CPp and PCp: 47,7, 36,1, 33,3%. Logistic regression analysis revealed a tendency for an increased chance of having stage 3–4 PC with FPG≥7,0 mmol/l (Exp (B)=3,205 95%CI 0,866–11,855, p=0,081) in PCp, but not in patients with pancreatic necrosis or “definite» СP.The frequencies of G/G (71,4, 74,7, 76,2%), G/A (26,2, 24,1, 23,8%) of TNF genotypes did not differ in APp, CPp or PCp, p>0,05. In PCp genotypes Arg/Arg, Arg/Pro, Pro/Pro polymorphism gene 72Arg/Pro TP53 in 2,4, 35,7, 61,9% of cases. No associations of GP≥7,0 mmol/l with TNF polymorphism in APp, CPp, PCp and with TP53 polymorphism in PCp were obtained. CONCLUSIONS: The frequency of FGP≥7,0 mmol/l did not differ for various pancreatic disease and was not associated with the risk of pancreatic necrosis and “defined” CP. The -308G/A polymorphism TNF gene did not differ in APp, CPp or PCp and was not associated with impaired carbohydrate metabolism. The 72Arg/Pro polymorphism TP53 gene in PCp was not associated with impaired carbohydrate metabolism.
