Objective To find out the diagnostic power and correlation between platelet-related parameters and inflammatory indicators in acute pancreatitis patients with different severity.Methods A total of 88 patients with acute pancreatitis diagnosed in West China Hospital of Sichuan University from January 2019 to August 2019 were enrolled in the retrospective study, including 58 mild acute pancreatitis patients and 30 severe acute pancreatitis patients. The patients’ platelet-related parameters and inflammatory indicators were collected. The platelet parameters and inflammatory indicators in different severity acute pancreatitis groups were compared and the diagnostic power and correlation were analyzed.Results The platelet count and plateletcrit of the severe group were lower than those of the mild group, the difference was statistically significant (Z=–5.502, –3.673; P<0.001). The immature platelet fraction, platelet distribution width, mean platelet volume and platelet-large cell ratio levels of the severe group were higher than those of the mild group (Z=–4.217, –2.998, –3.754, –3.816; P<0.05). Platelet-related parameters platelet count, immature platelet fraction, platelet distribution width, mean platelet volume, platelet-large cell ratio, plateletcrit and inflammatory indicators procalcitonin, interleukin-6 showed good diagnostic power with areas under under receiver operating characteristic curves greater than 0.75 in differentiating the severity of acute pancreatitis. Correlation analysis showed that immature platelet fraction was positively correlated with procalcitonin and interleukin-6 levels in patients with acute pancreatitis (rs=0.457, 0.385; P<0.05).Conclusions Immature platelet fraction is correlated with the severity of acute pancreatitis, and positively correlated with the levels of inflammatory indicators procalcitonin and interleukin-6.
