Abstract:
Objective:To investigate the clinical value of Tyro3/Axl/Mertk (TAM) receptor tyrosine kinase and ligands in severity evaluation for acute pancreatitis (AP).Methods:The peripheral blood and clinical data of 27 patients with AP admitted in the Department of Gastroenterology of Shanghai General Hospital from February 2020 to July 2022 were prospectively selected. The patients were divided in to mild AP group (MAP, n=13), moderately severe AP (MSAP, n=10) and severe AP group (SAP, n=4) according to the 2012-revised Atlanta classification for AP. Another 10 healthy normal subjects were selected as the control group. The general information, biochemical indicators and blood cell analysis of the patients were recorded, and the levels of serum Gas6, protein S and soluble Axl (sAxl) were measured by ELISA. Linear regression equations were used to analyze the correlation of serum Gas6, protein S and sAxl levels with the white blood cell (WBC) counts, neutrophil percentages, lymphocyte percentages, and monocyte percentages of each group, and to assess the clinical value of Gas6, protein S and sAxl in predicting the severity of AP patients. Results:Compared with the control group, the serum Gas6 level [(31.3±13.0)ng/ml vs (21.2±2.6)ng/ml], protein S level [(24.4±11.3)μg/ml vs (17.7±3.4)μg/ml], and sAxl level [(9.0±4.4)ng/ml vs (6.6±1.3)ng/ml] were significantly higher in the AP group. The Gas6 level was significantly higher in the SAP group (54.1±13.7 ng/ml) than in the MAP group (31.0±9.4 ng/ml) and the MSAP group (25.2±8.9 ng/ml), and the differences were statistically significant (all P value <0.05). The Gas6 level was significantly positively correlated with the WBC count ( r=0.1733) and neutrophils percentage ( r=0.4424), and negatively correlated with lymphocyte percentage(r=-0.363), with statistically significant differences (all P value <0.05). The levels of protein S and sAXL were positively correlated WBC count and neutrophil percentage, and negatively correlated with monocyte percentage and lymphocyte percentage, but the differences were not statistically significant. Conclusions:The serum levels of Gas6 increase significantly with the severity grading of AP, which may serve as a relatively good predictor for the early severity assessment of AP.
