THE ROLE OF ENDOTOXICOSIS AND INFLAMMATION IN DEEPENING THE PANCREATIC FUNCTIONAL INSUFFICIENCY IN CHRONIC PANCREATITIS IN COMBINATION WITH TYPE 2 DIABETES.

Objective: Aim: To analyze the state of parameters of inflammation, endotoxicosis, and their influence on the functional capacity of the pancreas in the comorbid course of chronic pancreatitis and type 2 diabetes mellitus (DM2).

Patients and methods: Materials and methods: 115 patients with CP in the phase of mild therapeutic exacerbation in combination with DM2 in the stage of subcompensation were examined. To assess the impact of comorbid DM2 on the clinical condition of patients with CP, a comparison group of 25 patients with CP in the exacerbation phase was included in the study. The assessment of the presence and depth of pancreatic exocrine insufficiency (PEI) was carried out according to the "gold standard" - determination of the content of fecal α-elastase-1, which was determined by the method of enzyme immunoassay using standard kits. As the main criterion for diagnosis and monitoring of DM, the measurement of HbA1c was used, which was determined by the method of ion exchange chromatography. C-reactive protein (CRP) was determined by the immunoturbidometry method by photometric measurement of the antigen-antibody reaction to human CRP antibodies; reference values of CRP in blood serum are up to 3 mg/l. Endogenous intoxication (EI) was assessed based on the levels of medium-mass molecules (MMM) - MMM1 and MMM2 at wavelengths 254 and 280 nm. The level of circulating immune complexes (CIC) was determined by the method of selective precipitation in 3.75% ethylene glycol followed by photometry.

Results: Results: Moderate and moderate inverse correlations were established between CRP and fecal α-elastase in CP and CP-DM2 comorbidity (r=-0.423 and r=-0.565, p<0.05). This proved a reliable influence of the depth of inflammation according to the content of CRP on the increase in PEI according to the level of fecal α-elastase, which was higher in the CP-DM2 comorbidity compared to CP. A deeper level of secretory insufficiency of the pancreas was established in CP with concomitant DM2, which deepened when the CRP level increased, compared to that in isolated CP: an increase in the strength of reliable direct moderate HbA1c-CRP correlations in patients with CP in combination with DM2 was proved in relation to such cases isolated CP (respectively r=0.313 and r=0.410, p<0.05).

Conclusion: Conclusions: We proved a reliable influence of the index of endogenous intoxication on the level of PEI according to the level of fecal α-elastase, which was higher in the CP-DM2 comorbidity compared to isolated CP: moderate and medium-strength inverse correlations were established IEI-fecal α-elastase in patients with CP and CP-DM2 comorbidity (r=-0.471 and r=-0.517, p<0.05). An increase in the strength of reliable direct, moderate, and moderate correlations between the levels of HbA1c and the index of endogenous intoxication in patients with isolated CP and CP-DM2 comorbidity (r=0.337 and r=0.552, p<0.05), which proved a deeper level of secretory pancreas insufficiency with concomitant DM2, which worsened with increasing endotoxicosis according to the value of the index of endogenous intoxication.
