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).
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: 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).
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.
分析慢性胰腺炎(CP)合并 2 型糖尿病(DM2)患者炎症、内毒素血症参数状态及其对胰腺功能的影响。
对 115 例处于轻度治疗加重期的 CP 患者和处于亚代偿期的合并 DM2 的 CP 患者进行检查。为了评估合并 DM2 对 CP 患者临床状况的影响,研究纳入了 25 例 CP 处于加重期的患者作为对照组。根据粪便α-弹性蛋白酶-1 的含量,采用酶联免疫吸附试验(ELISA)法检测,评估胰腺外分泌功能不全(PEI)的存在和严重程度,确定“金标准”。DM 的主要诊断和监测指标为糖化血红蛋白(HbA1c),采用离子交换层析法测定。采用比浊法测定 C 反应蛋白(CRP),根据人 CRP 抗体的抗原抗体反应进行光电比色测量;血清中 CRP 的参考值高达 3mg/L。根据在波长 254nm 和 280nm 处的中分子量物质(MMM)-MMM1 和 MMM2 的水平评估内毒素血症(EI)。采用 3.75%乙二醇选择性沉淀后比色法测定循环免疫复合物(CIC)水平。
在 CP 和 CP-DM2 合并症中,CRP 与粪便α-弹性蛋白酶之间建立了中度和中度负相关(r=-0.423 和 r=-0.565,p<0.05)。这证明了根据 CRP 含量评估的炎症深度对粪便α-弹性蛋白酶水平升高导致的 PEI 增加有可靠的影响,而 CP-DM2 合并症中的这种影响高于 CP。与单独 CP 相比,CP 合并 DM2 时胰腺分泌功能不全程度更深,CRP 水平升高时,这种情况会进一步加深:在 CP 合并 DM2 的患者中,HbA1c-CRP 相关关系的强度可靠地直接增强,与单独 CP 相关(分别为 r=0.313 和 r=0.410,p<0.05)。
我们证明了内毒素血症指标对粪便α-弹性蛋白酶水平的影响是可靠的,CP-DM2 合并症中的这种影响高于单独 CP:在 CP 和 CP-DM2 合并症患者中,建立了中度和中度强度的反向相关关系 IEI-粪便α-弹性蛋白酶(r=-0.471 和 r=-0.517,p<0.05)。在单独 CP 和 CP-DM2 合并症患者中,HbA1c 和内毒素血症指标之间可靠的直接、中度和中度相关关系的强度增加(r=0.337 和 r=0.552,p<0.05),这证明了 DM2 合并症时胰腺分泌功能不全程度更深,随着内毒素血症指标值的增加,情况会进一步恶化。
