Analysis of risk factors for acute pancreatitis with thrombotic diseases / 中华胰腺病杂志

ABSTRACT

Objective:To investigate the risk factors of acute pancreatitis (AP) complicated with thrombotic diseases.Methods:Clinical data of 5 223 patients with AP admitted to the General Hospital of Ningxia Medical University from January 2015 to September 2020 were retrospectively analyzed. They were divided into thrombosis group and non-thrombosis group according to whether they were complicated with thrombotic diseases. The following data were recorded gender, age, past history, time of onset, etiology, severity grade of AP, BISAP score, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer(D-D), fibrinogen(FIB), white blood cell count(WBC), platelet count (PLT), lactate dehydrogenase (LDH), blood glucose level, with or without hypoalbuminemia, hypertriglyceridemia and hypercholesterolemia, date of diagnosis, location of thrombus, clinical manifestations and anticoagulant therapy. Univariate and Logistic multivariate regression analysis were used to analyze the risk factors of AP complicated with thrombotic diseases. The receiver operating characteristic (ROC) curve was drawn, the area under the curve (AUC) was calculated, and the efficacy of independent risk factors in predicting AP complicated with thrombotic diseases was evaluated.Results:46(0.88%) of 5 223 patients with AP were complicated with thrombosis, which occurred 8.50(2.00-15.00) days after the onset of AP; the age of onset was 66 (52-74) years; the patients with thrombotic diseases were mostly SAP patients (23/46, 50%); the most common type was deep venous thrombosis in lower extremity (19/46, 41.3%); 37 patients (80.4%) received regular anticoagulant treatment after finding thrombus, and no bleeding was found during hospitalization. Univariate analysis showed that the age of patients with thrombosis was higher than that of patients without thrombosis, APTT value was prolonged, D-D value was increased, WBC was decreased and SAP was more in AP severity, the number of patients with BISAP score ≥3 was increased significantly, and the differences were statistically significant ( P<0.05). Multivariate logistic regression analysis showed that AP severity ( OR=3.017, 95% CI 1.799-5.061, P<0.001) and age ( OR=1.029, 95% CI 1.000-1.059, P=0.049) were independent risk factors for AP patients complicated with thrombosis. The AUC of AP severity and age in predicting AP complicated with thrombotic diseases were 0.714 and 0.625, respectively. The sensitivity was 67.4% and 47.8%, and the specificity was 70.6% and 77.9%, respectively. Conclusions:The severity grade and age of AP were independent risk factors for AP complicated with thrombotic diseases. Early vigilance and clinical intervention should be given.
