Analysis of the correlation between metabolic syndrome and recurrent acute pancreatitis / 中华消化杂志

ABSTRACT

Objective:To investigate the correlation between metabolic syndrome (MS)and recurrent acute pancreatitis (RAP).Methods:From June 1, 2012 to June 1, 2023, 463 patients with RAP (recurrent group) who visited the First Affiliated Hospital of Chongqing Medical University were retrospectively collected. The clinical data of 463 patients without RAP (non-recurrent group) during the same period were randomly selected. The patients in the recurrence group were treated at the First Affiliated Hospital of Chongqing Medical University for both initial acute pancreatitis and RAP. The differences in the proportion of patients combined with MS and its components (obesity (body mass index ≥25 kg/m 2), fasting blood triglyceride (TG) ≥1.7 mmol/L, hypertension, hyperglycemia, fasting blood high-density lipoprotein cholesterol (HDL-C) <1.04 mmol/L) between the two groups were analyzed by Chi-square test. Binary logistic regression analysis was used to identify the risk factors of acute pancreatitis recurrence. Results:Among the 463 patients in the recurrent group, there were 221 patients (47.7%) with MS, 276 patients (59.6%) with obesity, 223 patients (48.2%) with hypertension, 185 patients (40.0%) with hyperglycemia, and 365 patients (78.8%) with fasting blood TG ≥1.7 mmol/L. Among the 463 patients in the non-recurrence group, there were 95 patients (20.5%) with MS, 245 patients (52.9%) with obesity, 115 patients (24.8%) with hypertension, 92 patients (19.9%) with hyperglycemia, and 301 patients (65.0%) with fasting blood TG ≥ 1.7 mmol/L. The percentages of MS, obesity, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L of the recurrent group were all higher than those of the non-recurrent group, and the differences were statistically significant ( χ2=76.27, 4.22, 54.35, 44.55, 21.90; P<0.001, =0.040, <0.001, <0.001, <0.001). There was no statistically significant difference in the percentage of patients with fasting blood HDL-C <1.04 mmol/L between the recurrent group and the non-recurrent group (68.5%, 317/463 vs. 65.4%, 303/463, P>0.05). The results of binary logistic regression analysis showed that combined with MS ( OR=3.538, 95% confidence interval (95% CI) 2.647 to 4.728), hypertension ( OR=2.700, 95% CI 2.025 to 3.602), hyperglycemia ( OR=2.228, 95% CI 1.633 to 3.039), and fasting blood TG ≥1.7 mmol/L ( OR=1.757, 95% CI 1.276 to 2.421) all significantly increased the risk of acute pancreatitis recurrence ( P<0.001, <0.001, <0.001, =0.001). Obesity was not an independent risk factor for RAP ( OR=0.967, 95% CI 0.727 to 1.286, P=0.816). Conclusion:The combination of MS, hypertension, hyperglycemia, and fasting blood TG ≥1.7 mmol/L are independent risk factors for RAP.
