Impact of asprosin, interleukin-6, and adiponectin on exocrine pancreatic insufficiency in patients with type 2 diabetes mellitus and chronic pancreatitis

Le résumé fourni par la source

Exocrine pancreatic insufficiency (EPI) is a clinical condition often associated with chronic pancreatitis (CP) and type 2 diabetes mellitus (T2DM) leads to malabsorption and nutritional deficiencies, severely impacting patients’ quality of life. It has been identified that asprosin, a glucogenic protein, is a key player in carbohydrate metabolism and chronic inflammation. Elevated levels of asprosin, along with changes in interleukin‑6 (IL‑6) and adiponectin, may contribute to the pathophysiology of EPI in patients with T2DM and CP. Objective — to investigate the levels of asprosin, IL‑6, and adiponectin and their correlation with exocrine pancreatic function in patients with T2DM and CP. Materials and methods. The study included 100 patients treated at Kharkiv Regional Clinical Hospital from 2020 to 2022. Patients were divided into two groups: Group 1 (n=70) with comorbid T2DM and CP, and Group 2 (n=30) with T2DM alone. The control group included 20 healthy individuals. Blood levels of asprosin, IL‑6, and adiponectin were measured using immunoassays. Fecal elastase‑1 (FE‑1) levels were used to assess exocrine pancreatic function. Pearson’s correlation coefficient was calculated to determine the relationships between these markers. Results. Asprosin levels were significantly higher in Group 1 compared to Group 2 and the control group, with the highest levels observed in patients with comorbid T2DM and CP (10.06±3.56 ng/ml). IL‑6 levels were also elevated in Group 1 (64.44±4.35 pg/ ml), indicating heightened inflammation. Adiponectin levels were lower in Group 1 (2.80±0.38 ng/ml), correlating with worse metabolic profiles. FE‑1 levels were markedly reduced in Group 1 (142.2±6.3 mg/ g), confirming severe EPI. Significant correlations were found between asprosin levels and IL‑6 (positive correlation, r=0.49, p<0.01), as well as between asprosin levels and FE‑1 (negative correlation, r=–0.52, p<0.01). In the group of patients with isolated T2DM, significant moderate negative correlations were found between asprosin levels and adiponectin (r=–0.47, p<0.05) and FE‑1 (r=–0.44, p<0.05). The study also demonstrated a strong negative correlation between adiponectin and IL‑6 (r=–0.61, p<0.01) in patients with comorbid T2DM and CP. Conclusions. Elevated asprosin levels in patients with T2DM and CP are associated with increased inflammation and reduced exocrine pancreatic function. The significant correlations between asprosin, IL‑6, and FE‑1 suggest that asprosin could serve as a clinically valuable biomarker for assessing metabolic and inflammatory status in these patients. The findings highlight the complex interaction between metabolic and inflammatory pathways in the development of EPI.
