The diagnostic utility of mean platelet volume in acute pancreatitis: insights and inconsistencies.

BACKGROUND: Acute pancreatitis (AP) is a rapid inflammatory disorder of the pancreas that can range from moderate to severe, frequently linked to considerable morbidity and death. The prompt recognition of severe acute pancreatitis (SAP) is essential for appropriate care; yet, forecasting the severity of AP continues to be difficult. Mean Platelet Volume (MPV), a metric of platelet activity, has surfaced as a prospective biomarker for the severity of AP. This study sought to evaluate the effectiveness of MPV in forecasting illness severity in AP. METHODOLOGY: A randomized controlled trial was conducted at Yenepoya Medical College Hospital, involving 279 participants, including both healthy volunteers and AP patients. MPV levels were measured and analyzed in relation to disease severity, specifically focusing on the presence of pancreatic necrosis. RESULTS: In comparison to healthy controls (8.88 ± 0.97 fL), the study's result showed that MPV levels were somewhat higher in AP patients (9.43 ± 6.78 fL), although there was not a significant statistical difference between the two groups (P > 0.05). Nevertheless, it was revealed that individuals who had pancreatic necrosis had a significantly higher level of MPV (13.17 ± 1.7 fL) in comparison to those who did not have pancreatic necrosis (9.19 ± 0.86 fL), with a p-value of less than 0.05. A sub-optimal diagnostic effectiveness was established by the ROC analysis for MPV in predicting pancreatic necrosis, with an Area Under the Curve (AUC) value of 0.609. CONCLUSION: This study concluded that, although MPV levels were higher in AP patients, particularly those with pancreatic necrosis, the overall diagnostic performance of MPV was sub-optimal. The study highlights the need for additional research to better understand the role of MPV in assessing AP severity and to explore other potential biomarkers that could improve early risk stratification in clinical practice.
