BACKGROUND: The aim of the present study was to investigate risk factors for developing more severe pancreatitis, including moderately severe (MSAP) and severe acute pancreatitis (SAP), in patients admitted with mild acute pancreatitis (MAP).
MATERIAL AND METHODS: Patients admitted with MAP to our hospital from March 2013 to May 2016 were included and prospectively evaluated. Possible risk factors for developing MSAP or SAP were age, blood glucose level on admission, etiology, sex, Ranson score, amylase level, Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores, C-reactive protein (CRP) level, serum calcium level, visceral fat area (VFA), body mass index (BMI), whether this was the first episode of AP, and method of administration of octreotide. The effects of variables for developing MSAP or SAP were evaluated using univariate and multivariate logistic regression models. Mortality, hospital duration, and rate of ICU transfer of patients were compared between patients who developed MSAP or SAP and patients who did not.
RESULTS: A total of 602 patients admitted with MAP were recruited into this study (256 men and 346 women). Seventy-four patients (12.3%) developed MSAP or SAP. According to univariate logistic regression analyses, the results indicated that there were 5 significant differences between patients who developed MSAP or SAP and those who did not: VFA (>100 cm²) (p=0.003), BMI (≥25 kg/m²) (p=0.001), Ranson score(p=0.004), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.040). Further multivariate logistic regression analyses revealed that BMI (≥25 kg/m²) (p=0.005), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.004) were independent risk factors for developing MSAP or SAP in patients admitted with MAP. Moreover, patients who developed MSAP or SAP had a mortality rate of 5.4%.
CONCLUSIONS: Significant risk factors for developing MSAP or SAP in patients admitted with MAP included BMI (≥25 kg/m²), APACHE-II (≥5), and blood glucose level on admission (>11.1 mmol/L). These factors should be used in the prediction of more severe pancreatitis in patients admitted with MAP.
